Abstract
The invention discloses a three shaft sleeve blocking type lock, which comprises a shell and a lock cylinder inside the shell. The lock cylinder comprises a circular fixed shaft sleeve, an inner shaft sleeve and an outer shaft sleeve. A key is inserted from front ends of central holes of the circular fixed shaft sleeve, the inner shaft sleeve and the outer shaft sleeve sleeved together. A square chamber is arranged inside the shell. More than one blocking sheet grooves are vertically arranged on chamber walls on both sides at intervals. A hook-shaped locking plate which controls a circular outer shaft sleeve to rotate and a corresponding spring are respectively arranged in each blocking sheet groove. The lock with a structure and a key structure are simple in structure and low in cost. Repeatability of keys is greatly reduced due to match of a key rod and the circular inner shaft sleeve, match of a positioning frame and tooth width and opening grooves of the lock cylinder and the key, match of a key positioning block and the positioning frame on the key, as well as match of number of teeth and height of the key teeth and hook-shaped locking plates and an arc-shaped edge. The lock cylinder is mutually locked with a blocking groove through blocking heads of the hook-shaped locking plates, so that an anti-twisting capacity is strong. The three shaft sleeve blocking lock is suitable for cabinet locks, door locks and vehicle locks and the like.
Description
Technical field
The present invention relates to a kind of lock, especially anti-theft cylinder lock.
Background technology
Cylinder lock is traditional theftproof lock, and it is simple with structural principle, cost is low, easy to use and anti-theft effect is arranged and be widely used, and positive effect has been played in the country and people's property antitheft and protection.Cylinder lock mainly is through the cylindricality pellet shot from a slingshot but the twist lock core to be blocked, and reaches the purpose of lock; And each cylindricality pellet shot from a slingshot whether block be to be controlled and unblanked by the key tooth corresponding with pellet shot from a slingshot.Along with the development of society, the theftproof performance of existing this anti-theft cylinder lock descends greatly, is easy to twisted off by force the cylindricality pellet shot from a slingshot, but rotates the twist lock core and unblank.And the control of cylindricality pellet shot from a slingshot has only through the length of the key tooth of correspondence and controls, and the repeatability of key is big, is easy to copy, and causes burglary to increase, and shape is rung the stable of society.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, cost is low and theftproof good, and the repeated little three axle sleeve cassettes of key lock.
For reaching above-mentioned purpose, technical scheme of the present invention is:
