AI Technical Summary

Technical Problem

In existing helmet painting fixing devices, the assembly of the synchronization groove and synchronization positioning block is difficult and easily damaged, resulting in poor quality of synchronization rotation and a high risk of fatigue fracture of the bolt assembly.

Method used

The top view cross-sectional shape of the synchronous groove and synchronous protrusion is gradually reduced from bottom to top. The inclined plane fits together to form a wedge-shaped locking effect, which increases the contact area and friction, disperses the contact stress, and reduces the risk of bolt assembly breakage.

Benefits of technology

It improves assembly efficiency and the reliability of synchronous rotation, reduces the risk of bolt assembly breakage, and enhances the stability and service life of the structure.

Abstract

A helmet paint fixing device, comprising a helmet placing device and a rotating shaft, the rotating shaft is provided with a matching base, the helmet placing device comprises a base structure and a helmet placing support, the lower fixing seat of the base structure is connected with the matching base by a bolt assembly; the bottom surface of the lower fixing seat is provided with a synchronous groove, the top of the matching base is provided with a synchronous convex part, the top view cross-sectional shape of the synchronous groove and the synchronous convex part gradually decreases from bottom to top, which can facilitate the synchronous convex part to be quickly inserted into the synchronous groove; the synchronous groove comprises a positioning inclined plane inclined towards the center direction of the top of the synchronous groove, and the synchronous convex part comprises a matching inclined plane inclined towards the center direction of the top of the synchronous convex part; when the synchronous convex part is inserted into the synchronous groove, each matching inclined plane is attached to one positioning inclined plane, which ensures that the synchronous convex part can stably drive the lower fixing seat to rotate synchronously when rotating, improves the reliability of synchronous rotation, and reduces the risk of bolt assembly fracture.
