Description

The push-and-pull unlocking mechanism of electronic lock

Technical field

The utility model relates to a kind of unlocking mechanisms of electronic lock.

Background technique

Currently used electronic lock, including card lock, coded lock, Fingerprint Lock etc., door-opening mechanism is generally inside and outside all identical, It is all using press-down type, by pushing the handle of lock, to drive the square bar in handle middle shaft to rotate, to drive opening for lock body Latch mechanism rotation, final that lock tongue recycling is driven to enter in lock body, such door can open.Such lock handle is in order to hold It holds, typically strip, width is narrow, could be suitble to the grip of all size hand-type in this way.And if handle is wider, For example reach the width of credit card, then do not allow easy-to-hold, especially for the smaller people of hand, hand cannot just wrap up handle, Cannot hold with a firm grip lock handle, be not easy to have an effect, and can only press down.Wide lock handle is in addition to relatively more special in appearance, except unusual, There can also be biggish spatial position to place general electronic component, such as fingerprint inductor, password key on lock handle.Due to The wide lock handle of the above reason is more suitable for being made into push-and-pull opening door, convenient for having an effect.Since lock body is all canonical form, lock body is opened Lock square bar is perpendicular to door, as long as existing handle covers on square bar, lower door handle can make its rotation, and structure is simple. And pushing and pulling the handle to open the door is to move forward and backward, and the lock body needs of present canonical form will be moved forward and backward and change into rotary motion.

Summary of the invention

The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of push-and-pull unlocking machine of electronic lock is provided Structure is achieved through the following technical solutions:

A kind of push-and-pull unlocking mechanism of electronic lock, the mechanism for being installed in the panel of electronic lock vertically, the machine A structure generally rectangular box, including back box, cover the cover board in back box, main body is located in the box body and tail end reveals downwards Out the box body and tail end be provided with the square hole of bar piece and upper part be the catapult type connecting rod piece of U-shaped, upper layer be equipped with side tooth and Lower layer is equipped with the sleeve of the transmission tooth assembly of upper heel teeth, the intermediate square orifice for being provided with the sleeve for placing unlocking square bar；It is described Sleeve body is located in the box body and one end is stretched out by aperture corresponding on cover board, and the transmission tooth assembly is located at the box In vivo；The inner side edge of the connecting rod piece U shape mouth is equipped with tooth, and the outer ring of the sleeve is equipped with lower heel teeth；The connecting rod piece U-shaped mouth Tooth and the transmission tooth assembly upper layer side heel teeth it is ratcheting, in the lower layer of the transmission tooth assembly under heel teeth and the sleeve Heel teeth is ratcheting.The square hole of the bar piece of the connecting rod piece tail end is used to connect the dististyle of door handle tail end, in this way when on door handle When lower movement, then its dististyle drive link piece moves up and down, and the tooth of connecting rod piece U-shaped mouth then passes through the upper layer of transmission tooth assembly Tooth rotation is driven the lower heel teeth rotation of the corresponding rotate driving sleeve of lower layer's tooth of tooth assembly, thus the unlocking side in drive sleeve Bar rotation, i.e., be converted into rotary motion for the push-and-pull campaign of door handle.

Further, the tooth of the connecting rod piece, transmission tooth assembly and sleeve is straight-tooth.Processing and structure are simple, completely It can satisfy the demand of function.

Further, the transmission tooth assembly includes upper layer tooth and lower layer's tooth, the upper layer tooth and lower layer's tooth It is connected by connector.It is divided into that two pieces is easy to process and storage and transportation, manufacturing cost can be reduced.

Further, the number of teeth of the upper layer of the transmission tooth assembly, lower layer and sleeve is no more than five.

Further, two inner side edges of the connecting rod piece U-shaped mouth are respectively provided with three teeth.

The utility model has the beneficial effects that the unlocking mechanism of the utility model is generally box body, it may be convenient to be mounted on It locks in front and back panel, mechanism is especially suitable for using on the front panel of electronic lock, and side can still adopt in rear panel, that is, door Use traditional structure.Mechanism structure is simple, and part is few, easy to process, and reliability is high, realizes turning for the power of push-and-pull lock handle It changes, the advanced and high electric lockset of added value is especially suitable.
