CN201447953U - Improved cylinder body - Google Patents

Abstract

The utility model discloses an improved cylinder body, comprising a lock sleeve and a lock cylinder, wherein the lock cylinder is positioned in the lock sleeve; and the lock cylinder and the lock sleeve are provided with marble holes which have corresponding positions, are distributed in rows and are internally provided with marbles. The lock cylinder and the lock sleeve in the cylinder body are internally provided with four rows of marble holes; the marbles are positioned in the marble holes; and key holes on the lock cylinder are double S type. The effective marbles on the lock cylinder with the structure are up to eight, the quantity thereof also can be added according to the needs. As the quantity of the effective marbles is increased, the difficulty of unlocking for a thief is greatly increased, the anti-theft performance of a lock is improved, and anti-theft performance of the cylinder body is distinctive. In addition, the improved cylinder body has exquisite design, reasonable structure, advanced technique and excellent manufacture and increases the competitiveness of the product.

Description

A kind of modified tapered end

Technical field

The utility model relates to a kind of tapered end, specifically existing tapered end is carried out improved technology.

Background technology

Traditional lock, the lock core front end is the key inlet port, is provided with key groove hole in the lock core, and the slotted eye upper end is provided with the pellet shot from a slingshot hole, lock core is positioned at lock tube, the corresponding lock core marble hole of lock tube also is provided with the pellet shot from a slingshot hole, is provided with one deck pellet shot from a slingshot in the pellet shot from a slingshot hole in the lock core, and the corresponding one deck pellet shot from a slingshot in the pellet shot from a slingshot hole of lock tube correspondence is provided with two layers of pellet shot from a slingshot, two layers of pellet shot from a slingshot rear end are provided with one or two layers of pellet shot from a slingshot of spring roof pressure, the spring outer end is enclosed on the lock body, and the lock core rear end is provided with opening pin, opens lock in order to stir dead bolt.When on the key tooth makes gap between one deck pellet shot from a slingshot and the two layers of pellet shot from a slingshot just in time when lock core is parallel with the gap between the lock tube, key drives lock core and rotates and drive lock and open, on the contrary one or two layers of pellet shot from a slingshot interlace, lock core can not be rotated.Existing S type lock core is a single-row billiard, and effectively pellet shot from a slingshot is generally below five or five, and the lock core theftproof of this structure is bad, can not play good anti-theft effect.

Summary of the invention

The purpose of this utility model provides the good tapered end of a kind of theftproof.

The purpose of this utility model is achieved through the following technical solutions.

The utility model compared with prior art has the following advantages.

A kind of modified tapered end comprises lock tube and lock core, and lock core is positioned at lock tube, lock core and lock tube are provided with the pellet shot from a slingshot hole that the corresponding shape in a row in position distributes, pellet shot from a slingshot is provided with pellet shot from a slingshot in the hole, it is characterized in that: be provided with four row's pellet shot from a slingshot holes in described lock core and the lock tube, pellet shot from a slingshot is positioned at the pellet shot from a slingshot hole.

Keyhole on the described lock core is two S types.

Be provided with four row's pellet shot from a slingshot holes in lock core in the tapered end described in the utility model and the lock tube, pellet shot from a slingshot is positioned at the pellet shot from a slingshot hole, and the keyhole on the lock core is two S types.Nearly eight of effective pellets shot from a slingshot on the lock core of this structure, its quantity can also increase as required.Because effectively the quantity of pellet shot from a slingshot increases, thereby has increased the difficulty that robber person unblanks greatly, improved the theftproof performance of lock, make the utility model unusual on theftproof performance.In addition, the utility model design is exquisite, rational in infrastructure, technology is advanced, perfect in workmanship, has strengthened competitiveness of product.

Description of drawings

Fig. 1 is the structural representation () of the utility model modified tapered end lock tube;

Fig. 2 is the structural representation (two) of the utility model modified tapered end lock tube;

Fig. 3 is the structural representation of the utility model modified tapered end lock core.

The specific embodiment

Below in conjunction with accompanying drawing the utility model modified tapered end is described in further detail.

As Fig. 1, Fig. 2 and shown in Figure 3, modified tapered end described in the utility model mainly is made up of lock tube 1 and lock core 2, lock core is positioned at lock tube. and lock tube is a cylinder, in be provided with cylindrical hole, on the cylindrical wall of lock tube, be provided with four row's pellet shot from a slingshot holes 3, the orthogonal setting in adjacent row's pellet shot from a slingshot hole. lock core is a cylinder, be provided with two S type keyholes 4 in it, be provided with equally on the cylindrical wall with lock tube on four row corresponding pellet shot from a slingshot holes, pellet shot from a slingshot hole site, be provided with some pellets shot from a slingshot in the pellet shot from a slingshot hole. because the utility model has increased by two row's pellet shot from a slingshot holes on the basis in existing single-row billiard hole, in the lock core two S type keyholes, thereby effective pellet shot from a slingshot is reached more than eight, thereby has increased the anti-theft feature of lock.

Claims (2)

1. a modified tapered end comprises lock tube and lock core, and lock core is positioned at lock tube, lock core and lock tube are provided with the pellet shot from a slingshot hole that the corresponding shape in a row in position distributes, pellet shot from a slingshot is provided with pellet shot from a slingshot in the hole, it is characterized in that: be provided with four row's pellet shot from a slingshot holes in described lock core and the lock tube, pellet shot from a slingshot is positioned at the pellet shot from a slingshot hole.

2. modified tapered end according to claim 1 is characterized in that: the keyhole on the described lock core is two S types.
