As shown in fig. 1 to 4, the anti-impact lock provided in this embodiment is configured such that the lock plate and the lock tongue are not locked by using a conventional hook, but are changed into a straight bayonet pin and a lock tongue through-fit, so as to achieve the function of locking. The anti-impact lock comprises a lock bottom plate 1, a first pressing plate 11, a second pressing plate 12, a third pressing plate 13, a rotating piece 2, a clamping pin hole 21, a rotating shaft 22, a torsion spring 23, a straight clamping pin 3, a spring 31, a baffle plate 32, a motor 4, a cam 41, a protruding part 42, a microswitch 5 and a microswitch 6.
The rotary piece 2 is provided with a locking pin hole 21. The straight chucking pin 3 is coupled to the bottom lock plate 1 and is maintained perpendicular to the chucking pin hole 21, and the head of the straight chucking pin 3 can be inserted into the chucking pin hole 21. The card pin hole 21 is a circular hole, and the cross section of the head of the straight card pin 3 is circular. Or the card pin hole 21 is a square hole, and the cross section of the head of the straight card pin 3 is square. The card pin hole 21 and the head of the straight card pin 3 can be in other shapes matching each other.
The lock bottom plate 1 is provided with a rotating shaft bearing hole, and the rotating sheet 2 is provided with a rotating shaft mounting hole. The rotating shaft 22 sequentially passes through the torsion spring 23 and the rotating shaft mounting hole, and is finally fixed to the rotating shaft bearing hole on the lock base plate 1, as shown in fig. 4, so that the rotating piece 2 is connected to the lock base plate 1 by the rotating shaft 22. The side of the lock bottom plate 1 is provided with a convex part for being hung on the torsion spring 23, one end of the torsion spring 23 is hooked on the convex part, and the other end of the torsion spring 23 is hooked on the side surface of the rotating piece 2. In the free state, the rotary piece 2 is subjected to the torsion force of the torsion spring 23, and tends to rotate counterclockwise, and the rotary piece 2 tends to be opened automatically.
One end of the first pressing plate 11 is fixed on the lock bottom plate 1 through a screw, and the other end of the first pressing plate 11 is provided with a mounting hole through which the head of the straight clamping pin 3 passes and faces the rotating piece 2. One end of the second pressing plate 12 is fixed on the lock bottom plate 1 through a screw, the other end of the second pressing plate 12 is provided with a mounting hole, and the tail part of the straight clamping pin 3 passes through the mounting hole. More specifically, the first pressing plate 11, the second pressing plate 12 and the bottom lock plate 1 form a receiving space, and the straight locking pin 3 is received in the receiving space, and the head of the straight locking pin 3 is vertically arranged on the rotating piece 2. The straight bayonet pin 3 can perform telescopic movement in the accommodating space so as to lock and unlock the bayonet pin hole 21 of the rotary piece 2.
The motor 4 is installed on the lock bottom plate 1, and the third pressing plate 13 covers the motor 4. The third pressure plate 13 is fixed to the lock base plate 1, thus fixing the motor 4 at the same time. The motor 4 is connected to a cam 41, the cam 41 having a cam lobe 42. The cam 41 is configured to: the motor 4 can rotate and the cam lobe 42 contacts the baffle 32. Further, the cam boss 42 can rotate in the first direction, and after contacting the first surface of the stopper 32, it continues to rotate, offsetting the elastic force of the spring 31 and pushing away the linear click 3. The cam lobe 42 is also rotatable in a second direction, opposite the first direction, the cam lobe 42 contacting a second surface of the baffle 32 and limiting movement of the baffle 32.
The lock bottom plate 1 is provided with a microswitch 5 and a microswitch 6. The microswitch 5 is configured to: the rotary plate 2 rotates and activates the microswitch 5. The microswitch 6 is configured to: the cam 41 rotates and triggers the microswitch 6.
The working flow of the anti-impact lock in the embodiment is as follows:
when the lock bottom plate 1 is in a closed state, the straight clamping pin 3 clamps the position of the clamping pin hole 21, the straight clamping pin 3 is pressed by the supporting force provided by the spring 31 on the straight clamping pin 3, and the straight clamping pin penetrates through the rotating piece 2 to be in a locking state.
The lock base plate 1 is normally in a closed state, and when the lock base plate 1 receives a code scanning or other opening signal, the motor 4 rotates counterclockwise, and the cam boss 42 drives the straight bayonet pin 3. When the straight bayonet pin 3 is disengaged from the bayonet pin hole 21, the rotary piece 2 is opened by the torsion spring 23 and stays in the opened position under the blocking of the bent edge of the bottom lock plate 1, as shown in fig. 2. At this time, the motor 4 will continue to rotate, and when the cam 41 disengages from the straight latch 3, the straight latch 3 will return downward and abut against the rotary piece 2 under the action of the spring 31. After the straight bayonet lock 3 is reset, the micro switch 6 is switched off, and at the moment, the motor 4 stops rotating. At this point, the unlocking action is completed.
When the lock is closed, the opening of the lock tongue is vertically pressed, the rotating piece 2 can rotate around the rotating shaft 22 due to the eccentric design of the pressed point and the fixed shaft, and when the pressed point and the fixed shaft are pressed to a certain degree, the depth of the opening of the lock bottom plate 1 can play a role in stopping. At this time, the straight locking pin 3 falls into the locking pin hole 21 to lock the rotary piece 2. While the straight locking pin 3 presses the micro switch 5 again (simultaneously unlocking) when the action is completed. When the straight clamping pin 3 presses the microswitch 5, the switch sends out a signal, and at the moment, the motor 4 rotates anticlockwise for 15 degrees to finish locking. At this point, the lock is closed.
The utility model uses the straight bayonet lock to penetrate and lock the rotating piece; the opening on the rotating piece is used for inserting the lock tongue, the lock tongue exits, the torsion spring drives the rotating piece to rotate, and the lock is opened; and after the locking plate is locked, the straight bayonet lock can be locked by the reverse rotation of the motor, so that the aim of double insurance is fulfilled.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
