Abstract

The invention provides a grade-B lock cylinder provided with two shifting heads. The grade-B lock cylinder comprises two lock cylinder bodies, and the two lock cylinder bodies are mounted in a hole of a lock cylinder shell form the two ends correspondingly. A check ring groove is formed in each lock cylinder body. Two axial check rings are clamped into the check ring grooves in the lock cylinder bodies correspondingly. The lock cylinder bodies can rotate in the lock cylinder shell and cannot rotate in the axial direction. Shifting blocks are supported on the outer circles of the ends of the two lock cylinder bodies. Grooves are formed in the middle portions of the shifting blocks. A key stretches into a key hole to reach the grooves shown in FIG. 6, the key rotates to drive the lock cylinder bodies to rotate in the lock cylinder shell and to drive the shifting blocks to rotate at the same time, corresponding mechanisms are driven to act, and thus an unlocking function is achieved. The grade-B lock cylinder is composed of the key, the lock cylinder shell, the lock cylinder bodies, the two check rings and the shifting blocks, and characterized in that the two lock cylinder bodies are mounted in the lock cylinder shell, the check rings for shafts are used for limiting axial movement of the lock cylinder bodies, and the shifting heads are provided with the two shifting blocks which are supported on the outer circles of the lock cylinder bodies; and when the key is inserted into the key hole to drive the lock cylinder bodies to rotate, the shifting heads rotate at the same time, the two shifting blocks on the shifting heads rotate around the lock cylinder bodies at the same time, the corresponding mechanisms are driven to act, and thus unlocking or locking of a lock tongue is achieved.

Description

The B level lock core of 2 shifting blocks

Technical field

Patent of the present invention relates to prison safety-security area, refers more particularly to prison Zhong Jian room security protection door lock.

Background technology

The B level lock core only one of which shifting block that prison security protection door the most typically uses, limits B level lock core and uses The expansion on way.

Summary of the invention

It is an object of the invention to provide a kind of new lock core, this new lock core has 2 shifting blocks, makes lock Purposes is more extensive.

The present invention is made up of key, lock core shell, core, 2 back-up rings and shifting block, it is characterised in that 2 Individual core is contained in lock core shell, limits core with shaft block ring and moves axially, and shifting block has 2 shifting blocks, Being bearing on the cylindrical of core, when key inserts keyhole drive core rotation, shifting block rotates simultaneously, 2 shifting blocks on shifting block rotate around core simultaneously, drive associated mechanisms action, it is achieved dead bolt is opened or closed Close.

Accompanying drawing explanation

Fig. 1 is the front view of former lock core

Fig. 2 is the side view of former lock core

Fig. 3 is the A-A sectional view of former lock core

In Fig. 1 and Fig. 2,1-1 is lock core shell, and 1-2 is core, and core has circlip groove, and core is permissible Rotating in lock core shell, 1-3 is keyhole, and 1-4 is shifting block, and 1-5 is axial back-up ring, 2 cores Respectively after two ends are filled in lock core housing hole, axial back-up ring is snapped in the circlip groove on core, core Can only rotate in core shell and can not move axially；Shifting block is bearing on the cylindrical of core end, uses key Spoon stretches into keyhole in the groove of accompanying drawing 3, and key turns drives core rotate in lock core shell and carry Dynamic shifting block rotates simultaneously, drives associated mechanisms action, it is achieved kinetic energy of unblanking.

Fig. 5 is the side view of patent of the present invention

Fig. 6 is the A-A sectional view of patent of the present invention

The basic structure of patent of the present invention is essentially identical with original structure, only by 1 shifting block on original shifting block Change 2 shifting blocks into.In Fig. 4 and Fig. 5,1-1 is lock core shell, and 1-2 is core, and core has back-up ring Groove, 1-3 is keyhole, and 2-4 is shifting block, and having groove, 1-5 in the middle of shifting block is axial back-up ring.

Detailed description of the invention

2 cores load the hole of lock core shell from two ends respectively, core have circlip groove, respectively by 2 Axially back-up ring snaps in the circlip groove on core, core can in lock core shell inward turning then can not axially move Dynamic, shifting block is bearing on 2 core end cylindricals, has groove, stretch into keyhole with key in the middle of shifting block To the groove of accompanying drawing 6, key turns, drive core rotate in lock core shell and drive shifting block to revolve simultaneously Turn, drive associated mechanisms action, it is achieved kinetic energy of unblanking.

Patent of the present invention is made up of key, lock core shell, core, 2 back-up rings and shifting block, and its feature exists In, 2 cores are contained in lock core shell, limit core with shaft block ring and move axially, and shifting block has 2 Shifting block, is bearing on the cylindrical of core, and when key inserts keyhole drive core rotation, shifting block is simultaneously Rotating, 2 shifting blocks on shifting block rotate around core simultaneously, drive associated mechanisms action, it is achieved dead bolt is opened Open or close.

Claims

The B level lock core of 2 shifting blocks of patent the most of the present invention is by key, lock core shell, core, 2 back-up rings and shifting block Formed, it is characterised in that 2 cores are contained in lock core shell, limited core with shaft block ring axial Mobile, shifting block has 2 shifting blocks, is bearing on the cylindrical of core, and key inserts keyhole and drives core During rotation, shifting block rotates simultaneously, and 2 shifting blocks on shifting block rotate around core simultaneously, drive associated mechanisms Action, it is achieved dead bolt is turned on and off.
