Embodiments of the self-locking mechanism and the case assembly provided by the invention are described below with reference to the accompanying drawings.
In one embodiment of the self-locking mechanism of the present invention, as shown in fig. 1 and 2, the self-locking mechanism 10 comprises a lock base 11, a lock tongue 12, an elastic member 13 and a control part 14, wherein the lock tongue 12 and the control part 14 are arranged on the lock base 11, the lock tongue 12 is movable along a first direction relative to the lock base 11, the control part 14 is slidable along a second direction relative to the lock base 11, the control part 14 is connected with the lock tongue 12, the contact part of the control part 14 connected with the lock tongue 12 is an inclined surface and/or the contact part of the lock tongue 12 connected with the control part 14 is an inclined surface, the inclined surface (the inclined surface of the control part 14 and/or the inclined surface of the lock tongue 12) is inclined relative to the first direction, when the control part 14 slides along the second direction, the contact part of the control part 14 connected with the lock tongue 12 acts on the lock tongue 12 to enable the lock tongue 12 to move inwards along the first direction, and the elastic member 13 is connected between the lock tongue 12 and the lock tongue 12 to reset the lock tongue 12.
In the following detailed description and illustration, the contact portion of the control portion 14 with the lock tongue 12 and the contact portion of the lock tongue 12 with the control portion 14 are both inclined surfaces. The case where only the contact portion of the control portion 14 that is in contact with the lock tongue 12 is an inclined surface, or the case where only the contact portion of the lock tongue 12 that is in contact with the control portion 14 is an inclined surface is similar to the case where both are inclined surfaces, and detailed description thereof is omitted.
In this embodiment, as shown in fig. 3 to 7, the self-locking mechanism 10 may, for example, lock and unlock in a box assembly formed by a first box 20 and a second box 30 stacked in a vertical direction, and the self-locking mechanism 10 may specifically be disposed on the first box 20, and the second box 30 is disposed with a corresponding lock hole.
In this embodiment, the locking tongue 12 is used to lock or unlock the second case 30. The locking bolt 12 is provided on the lock base 11, which is movable in a first direction with respect to the lock base 11, and when the locking bolt 12 is extended, the locking bolt 12 is inserted into a locking hole on the second casing 30, thereby locking the second casing 30, and when the locking bolt 12 is retracted, the locking bolt 12 is separated from the locking hole 31 of the second casing 30, thereby unlocking the second casing 30.
In this embodiment, the control portion 14 is used to control the state of the locking bolt 12, mainly to control the retraction of the locking bolt 12. The control part 14 is arranged on the lock seat 11 and can slide along the second direction relative to the lock seat 11, and meanwhile, the control part 14 and the lock tongue 12 are in inclined surface connection. When the control portion 14 slides in the second direction, interaction occurs between the control portion 14 and the locking bolt 12 at the inclined plane where the control portion 14 and the locking bolt 12 meet, specifically, the inclined plane where the control portion 14 meets the locking bolt 12 applies a force to the locking bolt 12, so that the locking bolt 12 moves in the first direction, that is, the locking bolt 12 stretches in the first direction. In this embodiment, the inclined surface of the control portion 14 contacting the locking bolt 12 applies a force to the locking bolt 12 in a direction of the rear end (i.e., a retracting direction) of the locking bolt 12, and the locking bolt 12 is retracted backward by the force, and at this time, the locking bolt 12 is separated from the locking hole 31 of the second casing 30, and the second casing 30 is unlocked. In the above-described process, when the control unit 14 controls the expansion and contraction of the tongue 12 by sliding itself, the direction in which the tongue 12 expands and contracts and the sliding direction of the control unit 14 are in different directions.
Specifically, the inclination angle α of the inclined planes of the lock tongue 12 and the control portion 14, which are mutually connected, may be 30 to 45 ° with respect to the first direction.
In this embodiment, an elastic member 13 is provided between the lock base 11 and the lock tongue 12, which serves to control the extension of the lock tongue 12 (in the case where the control portion 14 applies no force to the lock tongue 12). In the process that the control part 14 applies the acting force to the lock tongue 12 to enable the lock tongue 12 to retract backwards, the elastic force of the elastic member 13 is overcome, the elastic member 13 receives the acting force and deforms in the process, and elastic potential energy is accumulated. When the control unit 14 stops applying the force to the latch 12, the elastic potential energy accumulated in the elastic member 13 is released, the elastic force of the elastic member 13 itself is applied to the latch 12, and the latch 12 is extended outward by this action, and at this time, the latch 12 is inserted into the lock hole 31 of the second casing 30, and the second casing 30 is locked.
In the self-locking mechanism of this embodiment, the control portion 14 for controlling the movement of the lock tongue 12 slides along the second direction, when the control portion 14 moves along the second direction, the contact portion of the control portion 14, which is in contact with the lock tongue 12, acts on the lock tongue 12 to retract the lock tongue 12 from the lock hole in the first direction, and when the control portion 14 does not apply a force to the lock tongue 12, the lock tongue 12 is protruded into the lock hole under the action of the elastic member 13. The above-mentioned self-locking mechanism has the extension direction of the lock tongue 12 and the sliding direction of the control part 14 in different directions, which facilitates the arrangement of the self-locking mechanism 10 on the side of the box assembly. Specifically, with the first casing 20 and the second casing 30 in the casing assembly, in the case where the self-locking mechanism 10 is provided on the side face of the first casing 20, the lock tongue 12 of the self-locking mechanism 10 can be inserted into the lock hole 31 provided on the side face of the second casing 30, and with the second casing 30, it is fixed by the lock tongue 12 of the self-locking mechanism 10 in a plurality of directions, so that a good locking effect can be achieved between the first casing 20 and the second casing 30.
In one embodiment of the self-locking mechanism, the lock tongue 12 comprises a head end 121, a tail end 122 and a connecting part 123 for connecting the head end 121 and the tail end 122 together, a mounting hole 111 penetrating in a first direction is formed in the lock seat 11, the connecting part 123 is inserted into the mounting hole 111, the head end 121 and the tail end 122 are respectively located on two sides of the mounting hole 111, a protruding step surface 1211 is formed at the joint of the head end 121 and the connecting part 123, the elastic piece 13 is a spring, the spring is sleeved on the outer side of the connecting part 123, one end of the spring abuts against the first step surface 1211, the other end of the spring abuts against the lock seat 11, and the inclined surface abutting against the control part 14 is formed on the tail end 122.
In this embodiment, the head end portion 121 is located at the front end of the lock tongue 12, and when the lock tongue 12 is extended, at least a part of the head end portion 121 is inserted into the lock hole 31 of the second casing 30, and when the lock tongue 12 is retracted, the head end portion 121 is completely separated from the lock hole 31 of the second casing 30. The distal end 122 is configured to be connected to the control portion 14, and has a slope connected to the control portion 14, and is configured to drive the latch bolt 12 to retract toward the rear end under the action of the control portion 14. The connection portion 123 is inserted into the mounting hole 111 for achieving fixation of the lock tongue 12 to the lock base 11, and for providing a spring at the outer side in the circumferential direction thereof.
In one embodiment of the self-locking mechanism, the distal end 122 of the locking bolt 12 and the connecting portion 123 are in a split structure and are fixedly connected.
In this embodiment, the connecting portion 123 and the head end portion 121 may be of a unitary structure, or may be of a split structure. When the connecting portion 123 and the head portion 121 are of a separate structure, they are fixedly connected, and when the head portion 121 and the connecting portion 123 of the latch bolt 12 are of a separate structure, the terminal portion 122 and the connecting portion 123 may be of an integral structure.
Specifically, the connection portion 123 and the head end portion 121 may be fixedly connected, or the connection portion 123 and the tail end portion 122 may be fixedly connected by a bolt.
In practical implementation, it is preferable to provide the connection portion 123 and the head end portion 121 as a single body, or to provide the connection portion 123 and the tail end portion 122 as a single body, and this is only necessary to connect the connection portion 123 to the head end portion 121 or the tail end portion 122, which are separate members, once, without connecting the connection portion 123 to the head end portion 121 and the tail end portion 122 twice, respectively.
In one embodiment of the self-locking mechanism, one of the control part 14 and the lock base 11 is provided with a sliding groove along the second direction, and the other is provided with a sliding rail corresponding to the sliding groove.
In the structure shown in fig. 2, the sliding groove is provided on the control portion 14 and is a sliding groove 141, and the sliding rail is provided on the lock base 11 and is a sliding rail 112.
In this embodiment, by providing the slide groove 141 and the slide rail 112, the control portion 14 can slide with respect to the lock base 11 in the longitudinal direction of the slide groove 141. In the case that the control portion 14 and the lock base 11 have the relative sliding, the lock tongue 12 can be driven to stretch in the first direction by the inclined surfaces of the control portion 14 and the lock tongue 12 connected with each other during the sliding.
In one embodiment of the self-locking mechanism, the slope of the interface between the control portion 14 and the locking tongue 12 is a conical slope or a truncated cone slope. In the structure shown in fig. 2, the inclined surface of the control portion 14 contacting the locking tongue 12 is a truncated cone-shaped inclined surface.
When the inclined surface in contact between the control portion 14 and the lock tongue 12 is a truncated cone-shaped inclined surface, as shown in fig. 2 to 7, when the control portion 14 continuously slides relative to the lock tongue 12, the truncated cone-shaped inclined surface on the lock tongue 12 is separated from contact with the inclined surface on the control portion 14, and the plane on the inner side of the truncated cone-shaped inclined surface of the lock tongue 12 can be abutted against the plane on the outer side of the inclined surface on the control portion 14, and at this time, the lock tongue 12 is locked and fixed in this state, and even if the control portion 14 is not pulled any more, the lock tongue 12 is not reset under the elastic force of the elastic member 13.
In a further embodiment, the control portion 14 is rotatably connected to the lock base 11, and the control portion 14 is perpendicular to the first direction with respect to the rotation surface of the lock base 11, on the basis that the slope that is connected between the control portion 14 and the lock tongue 12 is a conical slope or a truncated cone slope.
In this embodiment, the control portion 14 is rotatable to any direction in the radial direction about the lock tongue 12 in a plane perpendicular to the first direction, and in any direction, the control portion 14 is slidable relative to the lock base 11. That is, when the control tongue 12 is controlled to expand and contract in the first direction, the sliding of the control part 14 with respect to the lock base 11 may be in any direction without limitation. In comparison with the aforementioned embodiment in which the slide grooves and the slide rails are provided, the direction in which the control portion 14 slides with respect to the lock base 11 is specific, but in this embodiment, there is no such limitation, and the direction in which the control portion 14 slides with respect to the lock base 11 is arbitrary.
