Description

A kind of novel dispute lock

Technical field

The utility model relates to a kind of novel dispute lock.

Background technology

The dispute lock is a kind of lockset that we often can meet, and realizes the effect of opening the door, closing the door through the dead bolt of an activity of lock core control.The dispute lock generally all is the revolving body of the terminal connection of movable part that adopts lock core; Described revolving body is provided with an eccentric shaft; Described eccentric shaft inserts on the chute of the horizontal single-ended opening on the dead bolt, and eccentric shaft rotating band moving lock tongue stretches out, and playback then drives the dead bolt playback.

Existing lock core generally all adopts leaf structure, usually can only carry out 180 degree rotations in a semicircle district, normally forwards a locking plate clockwise to and hides, and forwards a locking plate counterclockwise to and stretches out.And the locking plate that forwards to counterclockwise that some special occasions needs is hidden, and forwarding a locking plate clockwise to stretches out, and existing lock construction can't be provided with variation accordingly.

Summary of the invention

In order to overcome the single deficiency that turns to that existing turning-bolt lock unblanks, the utility model provides a kind of can adjust the novel dispute lock of selecting the flexible rule of dead bolt.

The technical scheme that the utility model solves its technical problem is: a kind of novel dispute lock; Comprise a lock and the lock core of being located in the lock; Described lock core is the blade lock construction, also is slidingly equipped with the dead bolt of an above-below direction in the said lock, and said dead bolt can stretch out or be hidden in the lock; The movable part of said lock core is controlled said dead bolt through a motion transformational structure, and described lock core movable part end is extruded with one and connects projection; The motion transformational structure of said dead bolt comprises a gyration block, and described gyration block rear end is provided with link slot and is socketed on the connection projection, and the gyration block front end convexes with bumping square; Also comprise a trimmer, be provided with square groove in the described trimmer and be enclosed within on the bumping square that described trimmer front end also is provided with a cam pin; The lower end of said dead bolt is provided with a horizontally set and single-ended chute at dead bolt one side opening, and described cam pin inserts in the chute.

When the movable part of said lock core drives the cam pin rotation, can in chute, slide accordingly and convert rotatablely moving of eccentric shaft into dead bolt move up and down.

The utility model is consistent with the dispute lock of prior art in use, repeats no more at this.When needs conversions dead bolt stretch out rule the time, as long as change a direction with dead bolt is positive and negative, trimmer changes a direction up and down, makes cam pin be positioned at opposite location, dead bolt stretch out with indentation just with original be provided with opposite.

The beneficial effect of the utility model is: can be arranged on the positive and negative effect of playing the flexible rule of adjustment dead bolt of trimmer and dead bolt on the utility model through replacing.
