Abstract

The utility model relates to a lock core. A lock bladder in the lock core is sheathed in a lock sleeve. A cylinder and a spring are arranged inside a cylinder hole whose direction is vertical to the direction of a key groove and is on the lock bladder. The end surface of the cylinder adjacent to the key groove is in an arc shape, and another end of the key slot is a small cylinder. A groove is formed on the circumference of the small cylinder on the cylinder inside the cylinder hole. A horizontal pin groove is arranged on the vertical direction of the groove, the position of the horizontal pin groove adjacent to the lock sleeve is a large cylinder, and the large cylinder is matched with the V-shaped groove of the lock sleeve. A locking horizontal pin and a spring are arranged inside the large cylinder. The part of the locking horizontal pin adjacent to the lock sleeve is a large cylinder, and the outer end surface of the large cylinder is a circular arc. The key groove is arranged on the lock bladder in the lock core. The horizontal pin groove which controls the lock bladder to rotate inside the lock sleeve is arranged on the vertical direction of the groove inside each cylinder hole. The key groove of the lock core is in a square, a rectangle, a reverse trapezium, and a trapezium. The lock core has small processing working capacity, simple processing craft, and lower cost; meanwhile, the erroneous opening ratio of a lock is obviously enhanced.

Description

Lock core

Technical field

The utility model relates to a kind of lock, is meant a kind of lock core especially.Key inserts in the lock gall of lock core, and the pellet shot from a slingshot of the key of key control lock gall makes it key and can drive lock gall rotation, the unlatching of control lock.

Background technology

At present, lock mostly is cylinder lock, please refer to the elevation of lock gall in the existing lock core of Fig. 1, and twice key 30,31 is arranged on the lock gall of lock core, vertically has a plurality of pellets shot from a slingshot hole 13 on the per pass key 30,31, has transverse pin slot 12 on one of them pellet shot from a slingshot hole 13.Please refer to the profile of lock gall in Fig. 2 lock core again, the skiagraph of lock gall in Fig. 3 lock core, lock gall 4 is inserted in the lock tube 3 in its lock core, on lock gall 4 with in the pellet shot from a slingshot hole 13 of key vertical direction, pellet shot from a slingshot 2 and spring 5 are housed, its pellet shot from a slingshot 2 is an arc near the end face of key, the other end of its pellet shot from a slingshot 2 is a small cylinder, when key 1 inserts lock gall 4, in pellet shot from a slingshot hole 13 pellet shot from a slingshot 2 small cylinders around form one the circle groove 8, in groove 8 vertical direction transverse pin slot 12 is arranged, its transverse pin slot 12 is a large cylinder near lock tube 3 places, the V-type groove 9 of its large cylinder and lock tube 3 coincide, in locking lateral pin 6 and spring 7 are housed, its locking lateral pin 6 is a large cylinder near lock tube 3 parts, the outer face of its large cylinder is a circular arc.Its weak point is that twice key 30,31 is arranged on the lock gall of lock core, causes labor content big like this, the processing technology complexity, and cost improves.Vertically have a plurality of pellets shot from a slingshot hole 13 on the per pass key 30,31, one of groove 8 vertical direction have transverse pin slot 12 therein, and the wrong-unlocking rate of lock is not high.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of lock core is provided, and its lock core labor content is little, and processing technology is simple, improves the wrong-unlocking rate of lock simultaneously.

The purpose of this utility model can reach by following measure:

A kind of lock core, lock gall is inserted in the lock tube in its lock core, on lock gall with in the pellet shot from a slingshot hole of key vertical direction, pellet shot from a slingshot and spring are housed, its pellet shot from a slingshot is an arc near the end face of key, the other end of its pellet shot from a slingshot is a small cylinder, in the pellet shot from a slingshot hole on the pellet shot from a slingshot small cylinder around form one the circle groove, in the groove vertical direction transverse pin slot is arranged, its transverse pin slot is a large cylinder near the lock tube place, the V-type groove of its large cylinder and lock tube coincide, in locking lateral pin and spring are housed, its locking lateral pin partly is a large cylinder near lock tube, the outer face of its large cylinder is a circular arc, has one key in the lock core on the lock gall.The transverse pin slot that each groove vertical direction has the control lock gall to rotate in lock tube.

The key of lock core is square, rectangle, trapezoidal, trapezoid.

The utility model has following advantage compared to existing technology: change key into one owing to have two key on the lock gall in the lock core, its lock core labor content is little, and processing technology is simple, and cost is lower.Vertically have a plurality of pellets shot from a slingshot hole on the per pass key, the transverse pin slot that each groove vertical direction has the control lock gall to rotate in lock tube is so obviously improve the wrong-unlocking rate of lock.

The specific embodiment

Please refer to the elevation of lock gall in Fig. 4 the utility model lock core, have two key in the lock core on the lock gall and change key into one.Please refer to the skiagraph of Fig. 3 lock core again, vertically have a plurality of pellets shot from a slingshot hole on the per pass key, the transverse pin slot that each groove vertical direction has the control lock gall to rotate in lock tube.

When unblanking, key is inserted in the lock gall, all on a horizon, locking lateral pin 6 is under spring 7 effects for the groove 8 in each pellet shot from a slingshot hole 13, and locking lateral pin 6 inserts in the groove 8, and then lock gall 4 can rotate in lock tube 3, and lock is unlocked.

When key was transferred to from lock gall, not on a horizon, locking lateral pin 6 can not insert in the groove 8 groove 8 in each pellet shot from a slingshot hole 13, and then lock gall 4 can not rotate in lock tube 3, and lock is by the lock jail.

This lock core labor content is little, and processing technology is simple, and cost is lower.Obviously improve the wrong-unlocking rate of lock simultaneously.
