The cover plate 1 is provided with a clamping groove 11. The buckle 3 and the elastic component 4 are arranged on the fixed support 2, and the buckle 3 can push the elastic component 4 to generate elastic deformation along the direction parallel to the cover plate, so that locking and separation with the clamping groove 11 are completed.
The locking device of the invention can be used for locking and fixing any two mechanical structures and can also be used for locking and fixing a structure to be fixed, wherein the cover plate can be a part of an external mechanical structure. The embodiment is particularly applicable to a dustproof assembly for a projection device, wherein the cover plate 1 may be a separate cover plate or a part of a housing of the projection device.
The present embodiment is described by way of example as applied to a dust-proof assembly, wherein the dust-proof assembly includes the locking device of the present invention and a dust-proof structure fixed by the locking device. Specifically, the dust screen 5 is used as the content in the accommodating space formed by the cover plate 1 and the fixing bracket 2. The dust screen 5 is arranged along the direction parallel to the cover plate 1, and plays a role of dust prevention on the wind receiving surface of the cover plate 1. Of course, in alternative embodiments, the locking device can be used in other applications, and the cover plate 1 and the fixing bracket 2 can also be used for fixing other objects to be fixed, and the function and the purpose of the fixing device are determined according to actual needs, for example, the fixing device can also be adsorption particles with adsorption effect or odor removal effect. Of course, it is also possible that the cover plate 1 and the fixing support 2 are respectively part of two objects to be locked, and the locking and fixing can also be realized by the structure of the locking device of the invention.
The buckle 3 comprises a main body 31 and a hook 32 arranged on one side of the main body 31 close to the card slot 11, wherein the hook 32 is formed by bending and extending from the main body 31 to the cover plate 1. In a normal working state, the hook 32 is matched with the clamping groove 11 together to fix the buckle 3 and the cover plate 1. In practical application, besides the movable hook 32 on the buckle 3, a fixed hook is arranged on one side far away from the buckle, so that the buckle 3 can drive the distance between the hooks to change in the moving process, and the assembly and the disassembly of the product are facilitated.
The fixing support 2 is provided with a fixing part for fixing the spring positioning rod 41, one end of the spring positioning rod 41, which is far away from the head part, is fixed on the fixing part, one end of the spring 42 is abutted against the fixing part, and the other end is abutted against the buckle 3. The buckle 3 can drive the spring to compress or stretch in the moving process. Specifically in this embodiment, when buckle 3 is in the normal operating condition, spring 42 is in slight compression state to guarantee that the assembly is firm between couple 32 and draw-in groove 11, when applying an axial thrust at buckle 3 right-hand member and promote buckle 3, the spring further compresses, and the distance between couple 32 and the fixed couple reduces, and after external force removed, promotes buckle 3 outwards to remove under the elastic action.
The fixing support 2 is connected with the cover plate 1 through a screw 6, furthermore, a fixing column 21 is arranged on the fixing support 2, a fixing hole matched with the fixing column 21 is formed in the cover plate, and the screw passes through the fixing hole and is fixed on the fixing column 21.
Further, in the dust-proof assembly of the present invention, the dust-proof net 5 is provided with an escape groove 51 for escaping the buckle 3 and an escape hole for escaping the screw 6.
The invention also provides projection equipment, which comprises the dustproof component, wherein the projection equipment is provided with the air inlet, the dustproof component is arranged on the air inlet, at the moment, the cover plate on the dustproof component is the shell of the projection equipment, and the clamping groove 1 on the cover plate can be one air inlet of the projection equipment
Specifically, as shown in fig. 3, when an axial thrust was applyed in the right-hand member department of buckle, the effect of application can compress the spring ingeniously for couple on the buckle removes to the left side, and dustproof subassembly both sides couple distance reduces, can pass the slot hole of dustproof subassembly couple from the projector air intake at this moment, loosens afterwards to exert force and makes the buckle restore original position under the effect of spring restoring force, tightly fixes dustproof subassembly on the foraminiferous panel beating of projector air intake. When the dustproof assembly is disassembled, the disassembly of the whole dustproof assembly can be easily realized only by applying axial force at the right end of the buckle. The whole structure realizes firm stability after assembly and has high and flexible disassembly and assembly operability.
Different from the prior art, the invention has the beneficial effects that:
1. the locking device realizes the consistency of the external force and the motion direction of the locking part, saves the thrust and effectively prevents the locking phenomenon.
2. The invention belongs to elastic locking, the elasticity is more than 50 times of the gravity of a locking part in a working state, the locking is firm and reliable, and the possibility of loosening of the locking in a vibration environment is avoided.
3. The buckle is fixed on the spring positioning rod in a semicircular ring positioning mode, independent assembly is achieved, the buckle does not need to be assembled in a limiting hole together with the spring positioning rod, and the assembly process is effectively simplified.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
