Abstract

The utility model belongs to the technical field of locksets, in particular to a prying prevention lock cylinder which consists of a shell, a gear lock cylinder, a lock cylinder seat, limiting devices and a prying prevention fixed disc, and is characterized in that the lock cylinder seat is arranged in the upper end of the shell, the gear lock cylinder is positioned on the lock cylinder seat and fixed by the limiting devices at two sides, the prying prevention disc is positioned at the front end of the gear lock cylinder and on the shell, and two sides of the prying prevention disc are fixed by rivets. In the prying prevention lock cylinder, an original circular lock cylinder is improved to be the gear lock cylinder, and the prying prevention fixed disc is added, so that the prying prevention lock cylinder is simple in structure and convenient to use, and has a prying prevention function.

Description

The pick-proof lock core

Technical field

The utility model belongs to lock technology field, is specially the pick-proof lock core.

Background technology

Lock core is divided into European lock core, American screw thread core and Fire-proof lock lock core, and wherein European lock core is very universal, is widely used in lock series products such as various door locks, Fire-proof lock.The lock core size can be tailor-made according to the thickness of door, has 40mm-160mm long.But this lock core owing to be circular lock core, when unblanking, needs screw key 360 degree at every turn, can open lockset, uses inconvenient; And lock core and lock body only are connected and fixed by lock core below screw hole, when unblanking, and the application life that the easy double swerve of lock core reduces lock core; Moreover, there is not shelter between lock core and the lockhole slit, tamper-resistant function is not good.

Summary of the invention

The purpose of this utility model is in order to overcome the existing the problems referred to above of existing lock core, original circular lock core to be improved to the gear lock core, and increases the pick-proof fixed disk, with provide a kind of simple in structure, easy to use, have tamper-resistant function lock core.Its technical scheme is as follows:

The pick-proof lock core, form by shell, gear lock core, lock core base, stopping means, pick-proof fixed disk, it is characterized in that: it is inner that lock core base is positioned at the shell upper end, the gear lock core is positioned on the lock core base, stopping means by both sides is fixed it, the pick-proof fixed disk is positioned on gear lock core front end, the shell, and both sides are fixed by rivet.

Compared with prior art the utlity model has following beneficial effect:

1, by improving the gear lock core, only needing to rotate 135 degree can unblank, easy to use.

2, increased the pick-proof fixed disk, the gap between gear lock core and the lockhole has been filled up, gear lock core retaining in lockset, has been increased tamper-resistant function.

3, increased the pick-proof fixed disk, the gear by the outer end is fixed together lock core and lockset, and lock core can double swerve when unblanking, and increases the application life of lock core.

Description of drawings

Fig. 1 is a structural representation of the present utility model

1---shell, 2---lock core base, 3---stopping means, 4---the gear lock core, 5---the pick-proof fixed disk.

The specific embodiment

Below in conjunction with Figure of description the utility model is further described.

The pick-proof lock core, form by shell 1, gear lock core 4, lock core base 2, stopping means 3, pick-proof fixed disk 5, it is characterized in that: lock core base 2 is positioned at inside, shell 1 upper end, gear lock core 4 is positioned on the lock core base 2, stopping means 3 by both sides is fixed it, pick-proof fixed disk 5 is positioned on gear lock core 4 front ends, the shell 1, and both sides are fixed by rivet.

Lock core is put into lock body, screw is connected and fixed lock core and lock body by silk hole, below.

When opening the door or locking a door, key is inserted in the lockhole, only need ROT13 5 degree, can open or lock the door.Simultaneously, because the pick-proof fixed disk just fills up in the gap between gear lock core and the lockhole, gear lock core retaining in lockset, is increased tamper-resistant function.The pick-proof fixed disk, the gear by the outer end is fixed together lock core and lockset, and lock core can double swerve when unblanking, and increases the application life of lock core.

The utility model is simple in structure, easy to use, have tamper-resistant function, is fit to produce in batches.
