Abstract

The utility model relates to a trap type theft-proof lock with magnetic spring ball structures. The utility model has the structure that a key of a mechanical lock is inlaid with a fixed magnetic spring ball A (13), and a lock core (10) is provided with a blind hole which is opposite to the fixed magnetic spring ball (13) on the key, wherein, a movable magnetic spring ball (12) which can slide is arranged inside the hole; a lock (3) in a direction which is perpendicular to the axial direction of a blind hole of the movable magnetic spring ball is provided with a hole of which corresponds to the fixed magnetic spring ball A (13), wherein, the hole is provided with a fixed magnetic spring ball B (15) which has opposite magnetic poles with the movable magnetic spring ball (12). The utility model has high cipher value and prevents drilling, and is also hard for technical opening, so that even if the lock core is rotated by other foreign matters or methods, the lock can not be opened.

Description

Trap type magnetic pin structure anti-theft lock end

The utility model relates to the tapered end of the tapered end of theft-preventing mechanical lock tool, particularly mechanical door lock.

At present, commercially available all kinds of Mechanical theft-proof door locks are a lot, also extensively are that society accepts.Existing ball lock head though improve constantly the size of key and the theft preventing method such as anti-drilling of lockset, is difficult to prevent technical unlocking, and as long as lock core has been rotated just and lock can have been opened.

The purpose of this utility model provides a kind of trap type magnetic pin structure anti-theft lock end, not only can have high number of password, anti-drilling, also is difficult to technical unlocking, promptly uses other foreign matter or method that the lock core rotation also can't be opened lock.

Technical solution of the present utility model is the driver blade at existing machinery formula door lock, collar, tapered end, the corresponding pellet shot from a slingshot of tapered end and lock core hole, the decorative pearl on top of an official cap, flat pearl, spring, sealing bead, big envelope, decoration ring, on the basis of mechanical lock key, the utility model studs with on the key at mechanical lock decides magnetic pin A, on lock core, have with on the key decide the relative blind hole in magnetic pin position, slidably moving magnetic pin is arranged in the hole, with the tapered end in the axially perpendicular orientation of moving magnetic pin blind hole on, have and decide corresponding hole, magnetic pin A position, Kong Zhongyou is opposite with moving magnetic pin magnetic pole decides magnetic pin B.

The above moving magnetic pin also can change iron core into.

Described in the utility modelly decide magnetic pin B and fix by the screw in the same hole.

Operating principle of the present utility model is, when key that insertion matches, moving magnetic pin is held by the magnetic pin A that decides on the key, when going to the orientation of deciding magnetic pin B, will move magnetic pin and hold owing to decide magnetic pin A, and lock core still can rotate, and therefore locks to be unlocked.If open tapered end,, go to 90 when spending though this pass of common spring is cracked and lock core has been rotated with foreign matter or other method, moving magnetic pin is just held by the magnetic pin of deciding on the tapered end, make magnetic pin have half to be drawn onto in the tapered end, limited the rotation of lock core, lock is lockable.

The utility model has the advantages that both have high number of password, anti-drilling, be difficult to technical unlocking again, promptly use other foreign matter or method that lock core has been rotated also and lock can't have been opened.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 organigram of the present utility model;

Fig. 2 A-A profile construction of the present utility model schematic diagram.

According to Fig. 1, shown in 2, the utlity model has the driver blade 1 of common mechanical door lock, collar 2, tapered end 3, sealing bead 4, spring 5, flat pearl 6, the decorative pearl on top of an official cap 7, big envelope 8, decoration ring 9, lock core 10, key 11, the utility model particularly stud with on the key at mechanical lock decides magnetic pin A13, on lock core 10, be drilled with key and decide the relative blind hole in magnetic pin position, moving magnetic pin 12 is housed in the hole, with the tapered end 3 in the orientation of 12 one-tenths 90 degree of moving magnetic pin on be drilled with and decide corresponding hole, magnetic pin position, Kong Zhongyou decides magnetic pin B15 and screw 14, decide magnetic pin B15 and moving magnetic pin 12 for N extremely to the S utmost point, or S is extremely to the N utmost point.

Claims

1. trap type magnetic pin structure anti-theft lock end, comprise driver blade (1), collar (2), tapered end (3), tapered end (3) and the corresponding pellet shot from a slingshot hole of lock core (10), the decorative pearl on top of an official cap (7), flat pearl (6), spring (5), sealing bead (4), big envelope (8), decoration ring (9), mechanical lock key (11), it is characterized in that studding with on the key and decide magnetic pin A (13) at mechanical lock, on lock core (10), have with on the key decide the relative blind hole in magnetic pin (13) position, slidably moving magnetic pin (12) is arranged in the hole, with the tapered end (3) in the axially perpendicular orientation of moving magnetic pin blind hole on, have and decide corresponding hole, magnetic pin A (13) position, Kong Zhongyou is opposite with moving magnetic pin (12) magnetic pole decides magnetic pin B (15).

2. trap type magnetic pin structure anti-theft lock end according to claim 1 is characterized in that moving magnetic pin (12) also can change iron core into.
