Description

A kind of postposition mechanical puzzle lock

Technical field

The application that the utility model relates to mechanical code locks on door lock.

Background technique

In today that coded lock and smart lock are increasingly flourishing, the door of new house resident has generallyd use coded lock or intelligence Lock because coded lock and smart lock anti-theft performance are high, and prevent resident be locked in because key is left behind oneself outdoors this The generation of awkward deed, therefore coded lock and smart lock are more more and more universal in new house resident, but this phenomenon be frequently experienced in compared with To make the mechanical lock to turn the key in the lock still occupy main status in remote districts and small towns, but with people in flourishing area Living standard and antitheft consciousness raising, smart lock and coded lock can still popularize in remote districts and small towns, therefore right In still for the producer of production standard machinery lock, if marching coded lock and smart lock field will be awkward problem.

Summary of the invention

In order to solve the above technical problems, the purpose of the utility model is to provide a kind of postposition mechanical puzzle locks, should Postposition mechanical puzzle lock can not had to by carrying out the i.e. alternative conventional door lock key of certain transformation to original door lock assembly Carrying keys, turntable input password need to only be stirred by opening the door, and be offered convenience to people's life, safer, and key is avoided to lose Bring security risk is lost, simultaneously for still for the producer of production standard machinery lock, original production line is still given birth to as usual It produces, it is only necessary to increase certain structure, some small changes then are carried out to original lock core.

To achieve the above object, the utility model uses technical solution below:

A kind of postposition mechanical puzzle lock, including turntable with coded lock, cabinet, driving mechanism, follower and key cylinder, On the inside of Door lock, the turntable with coded lock is fixed on Door lock outer surface, the driving mechanism for the cabinet side It is located in the box body with follower, the key cylinder and follower are cooperatively connected；

The driving mechanism includes turntable input shaft, password locking plate and driving wheel, and the turntable input shaft is fixed on password It locks at center of turntable, and sequentially passes through key cylinder, cabinet, password locking plate and driving wheel, the driving wheel is equipped with groove；

The follower includes pull rod, rack gear, gear, transmission shaft, driving lever, output shaft and connecting rod, is consolidated on the rack gear Surely there is a screw, the pull rod A end cap is and free to rotate on screw, and the end the pull rod B is in hook-like, and the pull rod exists There is the pressure of perpendicular drive wheel surface to driving wheel, the rack gear is equipped with rectangular notch, and the rectangle lacks under the action of screw Mouthful side can with gear cooperate be driven, the transmission shaft A end cap in gear, the driving lever A end cap on the end transmission shaft B, Transmission shaft rotation can drive driving lever to rotate, and the output sleeve is fixed on box outer surface, and the output sleeve is at the end connecting rod A Interior, the end the connecting rod B is equipped with sliding slot, and the end the driving lever B is equipped with positioning pin, and the positioning pin passes through sliding slot, the driving lever rotation Link rotatable can be driven, so that output shaft be driven to rotate.

In the technical solution of the utility model, the turntable input shaft sequentially passes through key cylinder, cabinet, password locking plate And driving wheel, and since the length of key cylinder is less than the distance between turntable input shaft and transmission shaft, it is therefore necessary to it must be arranged The transmission mechanisms such as driving lever, output shaft and connecting rod enable rotational password lock turntable that key cylinder is driven to rotate, although if turntable is defeated Enter axis and be not passed through key cylinder, the installation of turntable with coded lock can be completed without using transmission mechanisms such as driving lever, connecting rods, but turns Disk input shaft passes through Door lock elsewhere, will certainly damage to the structure of Door lock, therefore turntable input shaft It is best selection across key cylinder.

Preferably, the box house is additionally provided with notch A and notch B, the notch A and notch B are located at rack gear The main function of two sides, the notch A and notch B are to limit the movement of rack gear in the other direction, so that rack gear is only specified Move back and forth on direction.

Preferably, there is gear teeth side parallel with the moving direction of rack gear in the rectangular notch of the rack gear.Work as password When inputting correct, in the groove that rotational password lock turntable may make the end drag hook B to be caught on driving wheel, turntable with coded lock is continued to rotate Pull rod just will be mobile with carry-over bar, when there is gear teeth side parallel with the moving direction of rack gear in the rectangular notch of the rack gear When, it may make the rotation distance of the gear of matched transmission to reach maximum.

Preferably, being additionally provided with key inserted sheet inside the key cylinder, the key inserted sheet is riveted on output shaft.

The utility model is mounted on door lock rear panel i.e. due to the technical solution more than using, using mechanical code lock In door inner panel, the output shaft of mechanical code lock is inserted directly into the key cylinder in conventional door lock, stirs door lock front panel i.e. Side panel top rotary table outdoors rotates clockwise coded lock output shaft and stirs key cylinder by a series of internal transmission mechanisms, It realizes and opens the door, the advantages of such mechanism is to be applicable to various types of door lock, only need to be to key lock on Door lock Core carries out small change；The utility model mainly substitutes conventional door lock key with mechanical code lock, can not have to take Band key, turntable input password need to only be stirred by opening the door, and be offered convenience to people's life, avoid key loss bring safe Risk, while the major part of mechanical code lock being embedded in door-plate, i.e., on the inside of main lock lock body, it can prevent criminal from passing through Tamper tool door lock becomes safer, and because of only more turntable with coded lock outside door lock, becomes simple and beautiful.
