Description

The burglary insurance lock cylinder

The utility model relates to a kind of burglary insurance lock cylinder.

In the background technology, the lock core that existing lockset adopts mostly is axial single-row billiard lock core, the unreasonable structure of this plug keyway and pellet shot from a slingshot, certain distance is arranged between key and the pellet shot from a slingshot, pellet shot from a slingshot does not seal key, makes master key can enter key, is easy to open lock, the lock core of this structure also makes other method for unlocking achieve the goal easily, and the theftproof and the reliability of lockset are relatively poor.

The purpose of this utility model has been to overcome the weak point of above-mentioned background technology, and a kind of burglary insurance lock cylinder is provided, and it is simple in structure, and is safe, can't open with the general mode of unblanking.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of burglary insurance lock cylinder, comprise lock core marble hole, pellet shot from a slingshot and pellet shot from a slingshot spring are housed in the pellet shot from a slingshot hole, and its special character is: the pellet shot from a slingshot aperture of described lock core is communicated with key to the key that is arranged in parallel side by side and penetrate lock core, and described key one end is provided with the key turns hole;

Above-mentioned key can be square or the rectangle key;

Above-mentioned pellet shot from a slingshot hole can be two rows, and coordination is arranged in axial plane both sides, lock core center;

Above-mentioned pellet shot from a slingshot hole can be two rows, and dislocation is arranged in axial plane both sides, lock core center;

But above-mentioned key turns hole straight line penetrates the key other end, is circular hole when key is anticaustic.

Fig. 1 is the cut-away view of the utility model burglary insurance lock cylinder;

Fig. 2 is the front view of the utility model burglary insurance lock cylinder plug body.

Number in the figure is described as follows:

The 1-plug body, 2-pellet shot from a slingshot hole, 3-dial axis, 4-key, 5-key turns hole.

Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, Fig. 2, comprise plug body 1, the double radially pellet shot from a slingshot hole 2 of lock core is parallel to the axial plane both sides, center of lock core side by side, every row has five pellet shot from a slingshot holes 2, equidistant between the two pellet shot from a slingshot holes 2, dislocation is arranged between two row's pellet shot from a slingshot holes 2, and key 4 one sides that pellet shot from a slingshot hole 2 penetrates lock core are communicated with key 4, make key 4 and bullet groove be all one.Key 4 is square or rectangle, and an end is provided with key turns hole 5, also is provided with dial axis 3 on the lock core and is used to reclaim dead bolt.Pellet shot from a slingshot and pellet shot from a slingshot spring are housed in the pellet shot from a slingshot hole 2, and lock core is packed in the lock body, interconnects by location eye on the lock core and the alignment pin between lock core and the lock body.When unblanking, key is inserted key 4, under the effect of pellet shot from a slingshot spring, the contact surface of lock core marble and tapered end pellet shot from a slingshot flushes with the bonding surface of lock core and tapered end, and key rotation hole 5 drives the lock core rotation, by the dial axis on the lock core 3 dead bolt is reclaimed, and lock is unlocked.When key is not inserted key, the bonding surface injustice of pellet shot from a slingshot and lock core and tapered end, key turns hole 5 just can not be rotated, and corresponding lock core can not rotate, and lock just can't be opened.When anticaustic, the key turns hole can be got through, like this, getting through the back, not have key turns hole, key when anticaustic be circle hole shape, but the lock core reversible kill two birds with one stone, very convenient.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, because plug keyway is circular hole, in the situation of not destroying lock body, uses existing any unblanking Method can not be rotated because of lock core, thus all can't open, security insurance, it is good to prevent opening theftproof performance.

2, owing to the totally-enclosed key slot of pellet, key slot and bullet groove open various no keys with being integrated The lock side formula can't achieve the goal, and is simple in structure, easy to use, and easily production and processing can be applicable to padlock, car On the various locksets such as lock, latch.
