Buckling cap type assembly tool for anti-theft lock cam mechanism

Abstract

The invention discloses a buckling cap type assembly tool for an anti-theft lock cam mechanism, relates to the field of manual tools, and mainly aims to solve the problem that manual assembly for an overload protective device of the anti-theft lock cam mechanism is difficult. The tool is used for assembling a circular table shaft, collision bead springs which are uniformly distributed in a radialdirection, and steel balls into a cam body. The circular table shaft is placed into a step hole of a slide tube, and one group of collision bead springs and steel balls is assembled into a pushing-extruding slide path of a sleeve disc and a collision bead slide path of the circular table shaft from four directions separately; in a process of moving a rotary-pushing handle plate to a left side endpoint, a rotary-pushing slide path of a rotary pushing disc simultaneously presses four groups of collision bead springs and steel beads into the circular table shaft through slide blocks, the cam body is buckled at the top end of the circular table shaft and the cam body is downwards pressed and pushed, the slide tube, the sleeve disc and the like synchronously return to keep the circular table shaft immovable until the circular table shaft enters the cam body to accomplish assembly. Upper and lower parts of the tool can freely rotate, and are limited by a using direction. Moreover, the buckling cap type assembly tool is easy in operation, is high in production efficiency, is simple in structure and is low in manufacturing cost.

Description

technical field [0001] The invention relates to a hand tool, in particular to a snap-on assembly tool for an anti-theft lock cam mechanism. Background technique [0002] At present, the core technology of the patent "a cross mechanical anti-theft lock with a fixed lock cylinder" (ZL201410020215.X) is being developed and applied. Its main features are: the technology cannot open the lock; The core is located in the door leaf, and is protected by anti-prying plate and anti-drilling sheet, and has the function of preventing damage by forced opening tools that ordinary anti-theft locks do not have. [0003] Accompanied by technology development, a number of patented products developed in the later period, including "Cylinder fixed cross mechanical anti-theft lock matched with fingerprint lock" (ZL201610990489.0), "A cam mechanism for fingerprint lock" (ZL201611045195.7), " Double plug-in anti-theft door and external hanging locking device" (ZL201610129609.8), "A forced reset de...

AI Technical Summary

Problems solved by technology

But the second method also has certain problems, that is, it is more difficult to assemble the circular table shaft and the cam body, because the circular table shaft needs to be loaded with ball springs and steel balls from four directions, and the four steel balls are compressed into the circular table shaft at the same time , to insert the round table shaft into the cam body as a whole, it is difficult to complete by manual operation without special tools or equipment, especially when the spring force of the bead spring is strong, manual assembly is more difficult
