Description

A quick disassembly and assembly locking device for lamp parts

Technical field

The present invention relates to the technical field of lamps, and more specifically, to a quick disassembly and assembly locking device for lamp parts.

Background technique

The various components of stage, film and television, and theater lighting fixtures can be detached from the lamp body at any time for the convenience of installation, packaging and transportation, or for use. However, in many existing designs, power supplies and other components are mounted on the lamp body through screws. Packing them together will increase the size of the package. If they are packaged separately, it will be inconvenient and time-consuming to use tools to assemble the lamp body, power supply and other components for on-site application. In the same way, when the installation site requires components such as the power supply and the lamp body to be installed separately or combined due to various reasons, tools must be used to fold and install the screws, which is time-consuming and labor-intensive. Therefore, a space between the components such as the power supply and the lamp body is designed. The quick locking device is very necessary.

Contents of the invention

In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a quick disassembly, assembly and locking device for lamp parts, which can realize quick disassembly, assembly and locking of multiple lamp parts.

In order to solve the above technical problems, the technical solution of the present invention is as follows: a quick disassembly and assembly locking device for lamp parts. The quick disassembly and assembly locking device is used to quickly assemble the separated first lamp part and the second lamp part into A whole, including a linear groove arranged in parallel on the first lamp component, a locking mechanism arranged on the second lamp component, the width of the groove opening is smaller than the maximum width inside the groove, and the locking mechanism The locking mechanism includes a locking block and a locking handle mechanism. The locking block includes a slide bar and two long strips arranged in parallel. Its thickness is smaller than the width of the groove opening, and its position is consistent with the recess on the first lamp component. The positions of the grooves correspond to each other and can extend into the groove. One end of the groove is fixed to the second component, and the other end is fixed with a slide bar. The slide bar includes a protruding portion in the direction opposite to the corresponding long plate. The protrusion ensures that the slider does not come out of the groove, and the slider can slide inside the groove. The locking handle mechanism can rotate the handle after the slider slides into the groove. And press the two long strips on the locking block against the groove wall. The groove can be provided on the lamp, or can be provided on an independent block structure, and the block structure is then fixed to the first lamp through bolts or other fixed connections. Preferably, the threaded pull rod also passes through a distance sleeve. The distance sleeve is arranged on the inside of the two long strips. The distance sleeve can ensure that the parts locked by the locking handle mechanism are not excessively deformed. The long strips are made of materials that can undergo elastic deformation, such as metal materials or high-strength polymer materials or composite materials. Metal materials are preferably used, among which aluminum materials are more preferred. The locking mechanism can be a simple screw locking structure or a simple clamping structure.

Further, the locking handle mechanism may specifically include a self-locking nut, a flat washer, a threaded pull rod, a locking block, a rotating shaft, and a handle. One end of the threaded pull rod is combined with the handle through the rotating shaft, and the other end passes through the lock. Tightly, two long strips and flat pads are fixedly connected to the self-locking nut. The parallel and opposite side of the two long strips is the inside, and the opposite side is the outside. The locking block and the locking handle are in the thread. The pull rod passes through the outside of the strip first. The flat washer and the self-locking nut pass through the outside of the strip after the threaded pull rod and can restrict the threaded pull rod from breaking away from the strip. One end of the handle is An eccentric mechanism. The eccentric rotates along the rotating shaft. The maximum and minimum distances between the eccentric edge and the center of the rotating shaft are G and H respectively. When the handle rotates to a certain position, the eccentric edge of the handle pushes the locking block. The long strip moves downward by a distance less than or equal to H-G, causing the linear groove walls on the first lamp component inside the two strip plates of the locking block to compress, thereby locking the first lamp component and the second lamp component.

Further, a side wall is fixed at one end of the two strips close to the second lamp component, and an arc-shaped structure is provided on the side of the side wall close to a certain strip. The wall thickness of the shaped structure is thinner than the wall thickness of other parts of the side wall. This is to facilitate the elastic deformation of the slider when it is stressed in the direction of the arrow.

Further, the width of the protrusion is greater than the width of the groove opening and less than the maximum width of the groove. In this way, the slide bar can slide into the groove from the entrance on the side of the groove. After matching, it can be initially fixed and then locked, which can make the connection more stable.

Furthermore, the cross section of the groove is C-shaped, and the cross section of the protruding part is circular or oval. Such a design can make the contact between the protrusion and the inner wall of the groove be an arc surface, which can prevent the edges and corners from damaging the groove, thereby reducing wear and extending the service life of the disassembly and assembly locking device.

Compared with the existing technology, the beneficial effects are: the device can realize rapid assembly and locking of multiple lamp parts; the locking effect of the device is better under the action of the locking device.

The protrusion ensures that the slider does not come out of the groove, and the slider is fixed to the second component. The slide bar can slide inside the groove, and the locking handle mechanism can rotate the handle after the slide bar slides into the groove and make the two long plates on the locking block press against the groove wall. tight.

The locking handle mechanism may specifically include a self-locking nut 1, a flat washer 2, a threaded pull rod 4, a locking block 5, a rotating shaft 6, and a handle 7. One end of the threaded pull rod 4 is combined with the handle 7 through the rotating shaft 6. , the other end passes through the locking block 5, the two upper long strips and the flat washer 2 and is fixedly connected to the self-locking nut 1. The parallel and opposite side of the two long strips on the locking block 5 is the inner side, and the opposite side The side is the outside, the locking limit block 5 and the handle 7 are on the outside of the long strip on the locking block 5 that the threaded pull rod 4 passes through first, and the flat washer 2 and the self-locking nut 1 are on the threaded pull rod 4 It passes through the outside of the long strip and can prevent the threaded pull rod 4 from breaking away from the long strip on the locking block 5. One end of the handle 7 is an eccentric mechanism, and the eccentric rotates along the rotating shaft 6, and the eccentric The maximum and minimum dimensions between the wheel edge and the center of the rotating shaft 6 are G and H respectively. When the handle 7 rotates to a certain position, the edge of the eccentric wheel of the handle 7 pushes the long plate on the limit block 5 to move downward by a distance less than or equal to H-G. The distance is such that the inner sides of the two long strips on the locking block 5 and the linear groove wall on the first lamp component are locked, thereby locking the first lamp component and the second lamp component.

A side wall is fixed at one end of the two strips close to the second lamp component, and an arc-shaped structure is provided on the side of the side wall close to a certain strip. The arc-shaped structural wall Thinner than the rest of the side wall.

The threaded tie rod 4 can also pass through a distance sleeve 3, and the distance sleeve 3 is arranged on the inside of the two long strips.

Preferably, the width of the protrusion is greater than the width of the groove opening and less than the maximum width of the groove.

The cross-section of the groove is C-shaped or other arc-shaped form, and the cross-section of the protruding part is circular or elliptical.

The materials used for the two long strips and side walls may be aluminum.

As shown in Figure 2, the first lamp component is provided with two grooves as shown in A, and the cross section of the groove tool portion is as shown in Figure 3. Figure 4 shows the second lamp component, which is equipped with a locking block shown in B and a locking handle mechanism shown in C. The locking block has two slide bars as shown in D in Figure 5. The head of the slide bar matches the two grooves shown as A on the first lamp component and can slide in either groove. The locking block is made of metal such as aluminum. The locking block is designed with an arc structure as shown in E in Figure 5. The corresponding wall thickness at the top of the arc is relatively thinner than other parts to facilitate the slider when it is stressed in the direction of the arrow. Easy to elastically deform. The locking handle mechanism is shown in Figure 6. It consists of a self-locking nut 1, a flat washer 2, a distance sleeve 3 (indicated by a dotted line), a threaded tie rod 4, a locking limit block 5, a rotating shaft 6, and a handle 7. The threaded tie rod 4 is combined with the handle 7 through the rotating shaft 6. The handle 7 has an eccentric structure. As shown in Figure 6, the G and H dimensions are the maximum and minimum dimensions of the eccentric from the central rotating axis. As shown in Figure 6, when the handle 7 rotates around the rotating axis 6 in the direction of the arrow to the position shown in Figure 7, the eccentric wheel on the handle pushes the locking limiter 5 downward to move the distance H-G, that is, the size F in Figure 6 is reduced. H-G, thereby achieving the locking effect of the parts between the lower plane of the locking limit block 5 and the upper plane of the flat pad 2. The distance sleeve shown in Figure 6 is to ensure that the parts locked by the locking handle mechanism are not excessively deformed. As shown in Figure 4, when the handle is turned in the locking direction, the eccentric wheel on the handle pushes the locking limit block, causing the upper slide bar of the locking block to deform in the locking direction so that the distance between the two slide bars becomes smaller.

During assembly, as shown in F in Figure 8, loosen the handle 7 of the locking handle mechanism in the second lamp component, align the two slide bars of the second lamp component with the two grooves on the first lamp component, and slide it in the direction of the arrow to the appropriate position. As shown in Figure 9, turn the locking handle in the direction of the arrow to the locking position. As shown in Figure 10, the eccentric structure on the lock handle causes the limit block to push the upper slide of the locking block to deform and move downward. The two grooves on the first lamp part and the two sliding bars on the locking block on the second lamp part (shown at G in Figure 10) are locked together through friction, so as to reach the first lamp part and the second lamp part. The purpose of assembling two lamp parts together is, on the contrary, as shown in Figure 10. When folding the second lamp part from the first lamp part, unscrew the handle in the direction of loosening and lock the second lamp part. The slide bar on the upper part of the block rebounds and loosens, so the two slide bars on the locking block on the second lamp part and the two groove matching parts on the first lamp part (shown at H in Figure 11) are loosened, so if As shown in Figure 12, the second lamp component can be slid out and detached through the two grooves on the first lamp component in the direction of the arrow.
