Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, specifically a positioning screw fixture for assembling a speaker outer decorative cover. Background Technology

[0002] A speaker enclosure, also commonly known as a speaker grille or speaker cloth, is a layer of material installed on the outside of a speaker enclosure. During installation, because speakers are cylindrical, the enclosure needs to be wrapped around the curved exterior of the speaker before being secured with screws.

[0003] However, bending the speaker grille requires both hands. A common solution is to use tape to stick it on, then screw it in and remove the tape. However, this method leaves glue residue that is difficult to remove, and the stability of the grille is affected by the adhesive strength. Therefore, a positioning and screw-locking fixture for assembling speaker grilles is proposed. Utility Model Content

The pressure sensor 7 detects the force exerted by the first fixing plate 10, ensuring there is no gap between the mesh cover and the upper cover. The up-and-down moving guide cylinder 16 controls the top plate 17 to descend. The inner platform 24 moves towards the center via the inner tensioning inclined pusher 27 and the cam follower 37. The inner tensioning boss 20 pulls the mesh cover inward. The two middle screws are locked first, and then the mounting block 5 is removed in sequence, causing the positioning posts 14 to move out. The four screws are then locked to complete the mesh cover fixing. Subsequently, the pressure head mechanism and the rear push mechanism are reset sequentially, and the product can be removed.
