Slide handle automatic returning and idling device

Abstract

The invention discloses a slide handle automatic returning and idling device, and relates to the field of anti-theft locks. Two slide blocks connected with return tension springs are used for respectively contacting with convex edges of driving wheels assembled on a handle rotating shaft in two directions; when a handle is rotated forwards and reversely within a certain angle, the slide blocks can push the handle to automatically return; when the handle is rotated beyond a certain angle, the convex edges of the driving wheels can cross over end angles of the slide blocks, and the handle idles; and when the opposite slide block is met, the opposite slide block can be deflected for avoidance. When the handle is rotated by one lap, the convex edges of two driving wheels are returned to an initial position again, and are tightly contacted with the end surfaces of the slide blocks, and the handle recovers an automatic return function. The device is suitable for a load provided with an overload protecting device in a lock body; and the handle can be automatically returned to achieve operation, and also can be idled for preventing damage and stolen opening of the lock.

Description

technical field [0001] The invention relates to the field of anti-theft locks, in particular to a sliding handle automatic reset and idling device. Background technique [0002] In the prior art, "lock cylinder fixed cross mechanical anti-theft lock" (patent number ZL201410020215.X), "a double-insert anti-theft door" (patent number ZL201610068454.1), "double-insert anti-theft door and external lock" "Closing device" (Patent No. ZL201610129609.8), "A digital code, a single key combination kit" (Patent No. ZL201610067763.7), "A model device with a key machine" (Patent No. ZL201610068057.4), "Cylinder-fixed cross mechanical anti-theft lock matched with fingerprint lock" (application number 201610990489.0), "cam mechanism for fingerprint lock" (application number 201611045195.7) and "reset mechanism of lock cylinder-fixed cross mechanical anti-theft lock" ( Eight invention patent applications, including application number 201710193748.1), all have special structure and performa...

AI Technical Summary

Problems solved by technology

Among them, all the above-mentioned patent applications do not mention the automatic reset of the handle. The actual operation method and existing problems are: after the handle is pressed down to unlock, the handle needs to be manually rotated to reset to a near-horizontal position, otherwise the key cannot be pulled out; After the anti-lift handle is locked, it is necessary to manually rotate the handle to reset. Although it is very light, if it is not reset, the handle will stop in an upward direction, which will affect the appearance

In this case, if only the automatic reset technology in the forward and reverse directions of the ordinary handle is used, the automatic reset device will fail after the handle is idling.

In addition, there are also patented products in the prior art that provide idling handles, such as "Overload Protector for New Intelligent Anti-theft Lock" (Patent No. 2015206788831). An overload protector is installed outside the lock body, but it is only limited to handles that can be idling. The automatic reset feature of the handle is not described at the same time, so the above-mentioned eight patent applications and other prior art do not address and solve the problem that the handle can be automatically reset in both forward and reverse directions and can also idle
