Abstract

The utility model discloses a door plug-in lock with key conveyor which consists of a key conveyor and a door plug-in lock. A locating steel ball in the key conveyor is used to locate and guide the key, a worm and a handwheel are also coordinated to realize the opening and closing to the door. The utility model has rational design, breaks the tradition that the key hole of the door plug-in lock is visible and the direct insert unlocking of the key is used, improves the anti-theft performance of the door plug-in lock due to the protection of the key conveyor to the door plug-in lock, and is suitable for popularization and application.

Description

The door mortise lock of band key conveyer

Technical field

The utility model belongs to door lock, particularly a kind of door mortise lock with the key conveyer.

Background technology

At present, the keyhole of conventional door lock singly is not that exposed and key is that straight cutting is gone into keyhole after twisting or rotation outside, lock core be easy to regard to destroyed property opened, also pried open easily, theftproof performance is relatively poor, safety should not be promoted the use of inadequately.

Summary of the invention

The purpose of this utility model provides a kind of door mortise lock with the key conveyer, and the positioning ball in the key conveyer positions the guiding of holding concurrently to key, cooperates worm screw, handwheel to carry out the folding of opposite house again.

The utility model is made up of a key conveyer and a door mortise lock, and the key conveyer is contained in above the mortise lock, and the round pin of key conveyer cooperates with recess on the mortise lock, and the keyhole of key conveyer communicates with the keyhole of a mortise lock.

Described key conveyer is by runner, round pin, handwheel, installing plate, the pot bar is formed, runner 2 is installed in installing plate 12 by round pin 8, between 13, round pin 8 one headband Ka Tai are pressed on the installing plate 13, another headband jump ring groove 9 cooperates with the lock body 20 of door mortise lock, the runner 2 of surface band annular knurl is provided with opening key 1 and cooperates with key 3, installing plate 13 is provided with positioning ball 4, positioning ball 4 cooperates with spring, installing plate 12 be provided with key pass hole 11 with the door mortise lock keyhole 19 cooperate, at installing plate 12, the pot bar 5 of band handwheel 6 also is installed between 13, between pot bar 5 and installing plate 7, positioning ball 7 is housed.

Described door mortise lock is made up of handwheel, eccentric wheel, compression spring, dead bolt, lock pellet shot from a slingshot, magnet, dead bolt 14 is contained in the lock body 20, be provided with 4 lock pellet shot from a slingshot holes 15 in the dead bolt 14, in lock pellet shot from a slingshot hole 15 lock pellet shot from a slingshot 16 is housed, lock pellet shot from a slingshot 16 cooperates with compression spring 17 and keyhole 19, and an end of dead bolt 14 is embedded with magnet 21, magnet 21 cooperates with eccentric wheel 22, have handwheel 23 on the eccentric wheel 22, friction top 26 is pressed on the lock body 20, and compression spring 25 is housed between dead bolt 14 and the friction top 26.

The utility model is reasonable in design, and it is exposed outside with the direct insertion tradition of unblanking of key to have broken key hole of door lock, and the protection of key conveyer opposite house mortise lock is arranged, and has improved the theftproof performance of a mortise lock, should promote the use of.

The specific embodiment

Shown in Fig. 1-4, the utility model is to have installed a key conveyer additional on former door mortise lock, and key will could cooperate with the keyhole of door mortise lock through the key conveyer, door could be opened like this.

The surface is provided with opening key 1 with the runner 2 of annular knurl rotates to the top, key 3 is inserted in this hole fully, Rotate 180 is ° to the bottom again, limited by the hold concurrently positioning ball 4 of guiding of location.The ring joint at key 3 tops is gone to the bottom by runner 2 through 180 °, with pot bar 5 engagement, forms similar activity like this and dials hand-screw and change hands wheel 6, and key 3 just is admitted to key and passes hole 11.Key passes hole 11 and communicates with the keyhole 19 of door mortise lock, so just can open and lock.Because positioning ball 7, pot bar 5 always are parked in the ring joint engagement at key 3 tops of certain position and runner 2.

When locking, under the effect of handwheel 23, eccentric wheel 22 overcomes the active force of compression spring 25, drives dead bolt 14 to left movement, until the peak of eccentric wheel 22.At this moment, 4 lock pellet shot from a slingshot hole 15 alignment, lock pellet shot from a slingshot 16 moves under the effect of compression spring 17, and dead bolt 14 is pinned.

When unblanking, key 3 is inserted keyhole 19, dead bolt 14 moves right under the effect of compression spring 25, and lock is opened.Magnet 21 has three effects, and the one, in the time of a little less than compression spring 25, auxiliary unlock deadbolt 14; The 2nd, under the effect of eccentric wheel 22 eccentric weights, leave dead bolt 14, the impact of 14 pairs of eccentric wheels 22 of dead bolt when just unblanking in the stop place of not having inspection eccentric wheel 22; The 3rd, dead bolt 14 produces shearing force under the effect of compression spring 25, make the abrasion aggravation of lock pellet shot from a slingshot 16, the sliding friction power that suction that magnet 21 and eccentric wheel made of iron are 22 and magnet 21 eccentric wheels are 22 is under the effect of compression spring 25, make eccentric wheel 22 by the power of peak to the minimum point rotation, shearing force is zero, and the abrasion of lock pellet shot from a slingshot 16 also are zero.Deviate from for anti-dead bolt 14, push down with friction top 26.
