Abstract
The utility model relates to the technical field of resetting devices and particularly relates to a resetting device for a door lock. The resetting device comprises a resetting bolt and a winding spring, wherein the resetting bolt is connected with a door handle and provided with a protruding block, the winding spring is wound on the protruding block, and the winding spring 2 is provided with two resetting pins 4 which are clamped by the inner portion of a lock case. When the door handle is rotated, the resetting bolt 1 drives the winding spring 2 to rotate, the two resetting pins 4 squeeze a clamping device in the lock case to generate elastic force, and when the door handle is released, the winding spring 2 enables the resetting bolt 1 to reset. The winding spring directly acts on the resetting bolt, so that the resetting device for the door lock reduces production cost and is simple in structure and convenient to manufacture.
Description
Technical field
The utility model relates to the resetting means technical field, particularly a kind of resetting means for door lock.
Background technology
The resetting means that is used for door lock links to each other with door handle, played the effect of switch door, traditional resetting means comprises the bolt that resets, the reset anchoring bit slice corresponding with the bolt that resets, reset and be provided with back-moving spring between anchoring bit slice and the lock housing, when turning the handle, the bolt that resets drives the anchoring bit slice motion that resets, and the described anchoring bit slice that resets can make back-moving spring stretch or compression, when unclamping door handle, back-moving spring sets back the bolt that resets by elastic force.But the manufacturing process complexity, the cost of production height.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, provides a kind of simple in structure, the resetting means of being convenient to produce.
For achieving the above object, the utility model is by the following technical solutions:
