Abstract

A lock shaft separating plate type double row pin tumbler lock cylinder is used for match and development of door industry locks and other various locks, and is provided with function of preventing technical unlocking, in an implementing technical scheme: an arc separating plate is designed and manufactured on a lock shaft, a hole groove is characterized in that, the machining external diameter is 45 degrees, the length is 32.6mm, the width is 8mm, and the thickness is 2.6mm; functions are that, firstly, spring pins in a lock liner are prevented from falling off and being exposed, secondly, spring pins opposite to straight plate key teeth are separated to form an obstacle layer, thereby preventing a technical unlocking tool from touching spring pins in the lock liner to perform unlocking, and realizing a matched stereo transverse tooth type key specially manufactured for need of unlocking, a rectangular hole is designed and manufactured below key transverse teeth, in unlocking, the lock shaft separating plate goes through the hole, and obstacles are instantly eliminated, thereby making the stereo transverse tooth key bit in contact with and matched with the spring pins in the lock liner to perform unlocking.

Description

Lock shaft partition board type double-row pin tumbler lock cylinder

Technical field

The utility model relates to a kind of lock shaft partition board type double-row pin tumbler lock cylinder, is mainly used in the supporting and exploitation of an industry lockset and other type lockset, has the function of anti-skilled unlocking.

Background technology

All kinds of locksets are various on the market, and performance is different, and the lock that has resembles common spring lock and is easy to be opened by the skilled unlocking instrument can't satisfy security needs, and prevention ability is poor.The utility model adopts lock shaft dividing plate technology, at lock core secret tunnel office is set, and guarantees lockset safety.

Summary of the invention

The utility model is mainly solved by following technical proposals for defects, adopts lock shaft dividing plate technology, is to be equipped with arc-shaped partition at lock shaft, and hole slot processing external diameter is 45 °, long 32.6mm, wide 8mm, thick 2.6mm.The function of lock shaft dividing plate: the one, block lock gall inner spring pellet and do not come off, do not expose; The 2nd, the isolation of spring marble that straight plate key bit is relative makes the skilled unlocking instrument can't touch in the lock gall pellet and can not unblank.Realization unblanks to surmount the obstacle of lock shaft dividing plate, and special a kind of three-dimensional contrate key just can be unblanked.

Its technical scheme is: key bit is transverse teeth, and contrate below designs and produces a rectangular hole, and the lock shaft dividing plate passes from the hole when unblanking, and the interior spring marble of the contrate of three-dimensional key and lock gall contacts and matches and unblank.

The beneficial effect that the utility model brings: simple in structure, easy to operate, have reliability and safety.

The specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is further described in detail.Basic structure mainly is comprised of lock housing 9,

lock gall

5,4 three members of lock shaft, and lock shaft 4 is maincenters of lock, uses special three-dimensional contrate key unlocking.Design and produce lock shaft dividing plate 3 formula double rows spring lock cores, need to use the 45# steel material, fineness 8-9 does not need heat treatment.

The utility model adopts lock shaft dividing plate 3 technologies, function is that one is to block lock gall 5 inner spring pellets not come off, do not expose, the 2nd, lock core is set takes precautions against office, the spring marble isolation that straight plate key bit is relative forms barrier layer, prevent that the skilled unlocking instrument from touching the spring marble in the lock gall 5 and can not unblank, optimal way is to design and produce arc-shaped partition at lock shaft 4, and hole slot processing external diameter is 45 °, long 32.6mm, wide 8mm, thick 2.6mm.

[0014] the utility model technical scheme of unblanking is, special a kind of three-dimensional contrate type key, key contrate below designs and produces a slot, and lock shaft dividing plate 4 passes from the hole when unblanking, and three-dimensional contrate key bit and lock gall 5 interior spring marbles contact and match just can unblank.
