Locking device and dustproof components and projection equipment

Abstract

The present invention provides a locking device, a dust-proof assembly and a projection device. The locking device includes a fixed bracket, a cover plate covered on the fixed bracket, a buckle and an elastic component arranged on the fixed bracket. An accommodating space is formed between the cover plate and the fixed bracket, the cover plate is provided with a slot matching the buckle, and the buckle can push the elastic member to produce elastic deformation along the direction of the cover plate, Thus, locking and separating from the card slot are completed. When an axial thrust is applied to the right end of the buckle, the elastic part can be skillfully compressed, so that the hook on the buckle moves to the left, and the hook can pass through the slot on the cover plate at this time. Then the applied force is released so that the buckle returns to its original position under the action of the elastic restoring force, thus realizing the assembly of the locking device. When disassembling, it can be easily disassembled only by applying axial force on the buckle. The whole structure not only realizes the firm stability after assembly, but also has highly flexible disassembly and assembly operability.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and in particular relates to a locking device for disassembling and assembling dustproof components. Background technique [0002] At present, locking devices are widely used to connect and fix at least two parts detachably, so as to replace the contents in the space formed by the at least two parts, such as the locks used for disassembly in the dustproof assembly of cinema projectors on the market Most of the locking devices are disassembled by pushing the locking parts sideways, so that the direction of the external force is perpendicular to the moving direction of the locking parts, which makes it more difficult to disassemble, which also determines that the locking force will not be too large , otherwise the locking parts are easy to be stuck and difficult to push, and the small locking force will directly lead to the weak locking. If the locked components are vibrated to a cert...
