Abstract

The utility model relates to the lock field, in particular to a lock core with anti-prizing, anti-drilling and anti-pulling functions. The utility model comprises a lock core housing, a plurality of rows of bolt holes, two anti-drilling bolts in the bolt holes of the front first rows, i.e. a left row and a right row, springs on the two anti-drilling bolts and copper door-sealing balls on the springs; lower bolts in the other a plurality of bolt holes, anti-prizing I-shaped upper bolts and springs and copper door-sealing balls on the upper bolts are also provided; moreover, anti-drilling holes are opened at the top of the lock cores at the two sides, i.e. the left side and the right side at the middle of the bolt holes at the two rows, i.e. the left row and the right row, and the anti-drilling holes are internally provided with anti-drilling pins for the lock core top. The utility model is characterized in that the two ends of the lock core are provided with anti-drilling and anti-pulling iron pieces; based on the prior anti-prizing and anti-drilling structure of an I-shaped anti-prizing bolt, anti-drilling bolt and anti-drilling pin, the two ends of the lock core are provided with anti-drilling and anti-pulling iron pieces keeping the drilling and pulling tools of the thief out of the lock core key, thereby further enhancing the anti-drilling function and ensuring the realization of the anti-pulling effect, being a real three-resistance lock core.

Description

The anti-lock core that pulls out of a kind of Prying-resistant and drilling-resistant

Technical field

The utility model relates to field of lockset, and particularly a kind of have an anti-function lock core that pulls out of Prying-resistant and drilling-resistant.

Background technology

Existing lock core is generally in order to reach tamper-resistant function, and the last pellet shot from a slingshot of lock core adopts I shape pellet shot from a slingshot 6, increases the purpose of difficulty when reaching picking lock.Another kind of lock core is on the basis of last pellet shot from a slingshot with the I shape pellet shot from a slingshot, has adopted anti-drill pin 4,12 (Fig. 4) and anti-drilling pellet shot from a slingshot 7 (Fig. 4,6).Though this variation has reached the anti-drilling again function of pick-proof, prevent pulling out indifferent.Pulling out in face of the lock tool, traditional Prying-resistant and drilling-resistant lock core holds can't stand that this kind destructiveness unblanks, and this also is the weak link of traditional Prying-resistant and drilling-resistant lock core.Afterwards, the anti-tapered end that pulls out that on the basis of Anti-drilling lock, occurs, its function is to realize by segmentation, opens the wide groove of 1.0mm at common position, one pellet shot from a slingshot hole, Anti-drilling lock middle part, uses plastic sheet 11 (Fig. 4,5) to seal up a door then.

As suffer that destructiveness pulls out lock, and then forward part disconnects, and still can work in the rear section.Shortcoming be pull out after, tapered end is just scrapped, and can't utilize again.As pull out and carry out again pulling out for twice drawing after drawing once, equally also can extract, so also can only be anti-pulling out on the relative meaning.

Summary of the invention

The purpose of the utility model is to remedy above-mentioned deficiency, disclose to society a kind of simple in structure, really can the anti-lock core that pulls out of Prying-resistant and drilling-resistant, the particularly anti-strong lock core of function that pulls out.

The technical solution of the utility model is achieved in that

The anti-lock core that pulls out of a kind of Prying-resistant and drilling-resistant comprises lock core shell, the number row pellets shot from a slingshot holes on the lock core shell, the pearl of sealing up a door of spring, the copper on the spring on two the anti-drilling pellets shot from a slingshot up and down in last row's pellet shot from a slingshot hole, the left and right sides, the anti-drilling pellet shot from a slingshot; Following pellet shot from a slingshot in other several pellet shot from a slingshot holes, pick-proof I-shaped go up pellet shot from a slingshot, go up spring on the pellet shot from a slingshot and the copper pearl of sealing up a door; About lock core top, both sides up and down in the middle of the preceding two row pellet shot from a slingshot holes open anti-boring, establish lock core top anti-drill pin in the anti-boring; It is characterized in that head place, lock core two ends sets up defences and bores the anti-iron plate that pulls out.

Head place, described lock core two ends sets up defences and bores the anti-iron plate that pulls out is 55 degree-65 degree high rigidity steel discs.The thickness of described lock core two ends head 55 degree-65 degree high rigidity steel discs is 2.5mm-3.1mm.

The utility model has the advantages that:

On existing basis of establishing I-shaped pick-proof pellet shot from a slingshot and anti-drilling pellet shot from a slingshot, this Prying-resistant and drilling-resistant of anti-drill pin, set up defences and bore the anti-iron plate that pulls out at head place, lock core two ends.Anti-drilling anti-pull out iron plate with brill, the instrument of pulling out of stealer refuse outside lock core keyhole, further strengthened anti-drilling function, guaranteed anti-realization of pulling out function, really become a pick-proof, anti-drilling, the anti-Three-protecting lock core that pulls out.

The specific embodiment

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

The anti-lock core that pulls out of a kind of Prying-resistant and drilling-resistant of the utility model comprises lock core shell 1, the row of 12 on lock core shell pellet shot from a slingshot hole 2 (Fig. 1,2), spring 5, the copper on the spring on two the anti-drilling pellets shot from a slingshot 7 up and down in last row's pellet shot from a slingshot hole, the left and right sides, anti-drilling pellet shot from a slingshot pearl 3 of sealing up a door; Following pellet shot from a slingshot 9 in other 10 pellet shot from a slingshot holes, pick-proof I-shaped go up pellet shot from a slingshot 6, go up spring 5 on the pellet shot from a slingshot and the copper pearl 3 of sealing up a door; About lock core top, both sides up and down in the middle of the preceding two row pellet shot from a slingshot holes open anti-boring 10 (Fig. 2), establish lock core top anti-drill pin 4 in the anti-boring; It is characterized in that head place, lock core two ends sets up defences and bores the anti-iron plate 8 (Fig. 1) that pulls out.

Head place, described lock core two ends sets up defences and bores the anti-iron plate 8 that pulls out is 55 degree-65 degree high rigidity steel discs, and its thickness is 3.0mm.

The utility model has saved lock core drilling-preventing pin 12 (Fig. 6), has reduced cost.And process is heat treated, hardness is 56 degree, and thickness is that the high rigidity steel disc of 3.0mm is prevented pulling out iron plate 8 rivetings at head place, lock core two ends, has both further strengthened anti-drilling function, has guaranteed anti-realization of pulling out function again.
