(1) lock core is with three layer construction, and it is main organizing shell fragment more, causes loosely organizedly, and part is thin, can not bear the test of destruction.
(2) the insertion key makes the lock core unlatching and extracts key Lock cylinder idling all will be gone back to lock core on same point, no matter be technical unlocking or open with former key, all have tangible power poor when lock core forwards this to, this point is easy to be cracked by the lawless person or whole lock core is destroyed and unblanks.
Summary of the invention
The purpose of this utility model provides a kind of firm in structure, and the lawless person is difficult to find and cracks a little, prevents to rotate lock gall by force and whole lock core also can not be destroyed, and has the anti-theft security tapered end that anti-omnipotent key and special tool are opened.
The utility model is realized by following technical proposals:
A kind of anti-theft security tapered end, comprise shell, lock core, Lock Lee, be provided with rotary-type cavity in the shell, lock core is installed in the rotary-type cavity of shell, described lock core comprises lock gall, the lock pearl, spring, lock pin, axis along lock gall in lock gall is provided with the key slotted eye to direction, the lock pearl, spring is installed on the lock gall, it is characterized in that: the axis along lock gall is provided with the lock pin groove of placing lock pin on lock gall to direction, lock pin is elongated and be installed in the lock pin groove, tail end-side at lock gall is provided with the fully moving device that coaxial line is installed, on fully moving device, be provided with and the corresponding recess of lock pin, be provided with at interval between the tail end of lock gall and the fully moving device, fix in the lock pin groove by latch lock when lock pin is static, Lock Lee is connected and is equipped with on the moving device.
The both sides of described lock pin are provided with some paired slotted eyes along the length direction of lock pin, be provided with the spaced lock hole of bead and be arranged on the both sides of lock pin groove to direction at the axis of lock gall upper edge lock gall, the lock hole of bead is through to the key slotted eye by the lock pin groove, the lock pearl all is installed in the lock hole of bead, lock gall becomes one group along the axis of lock gall to spring groove and adjacent two spring grooves that direction is provided with ring-type, in each spring groove spring is installed, wherein the two ends of the wherein spring of each group in spring groove all are connected with a corresponding top of locking pearl, and each spring all in the form of a ring and be provided with opening.
The afterbody of described lock gall is provided with lever, and the top of lever is connected on the lock pin, and the lever both sides are equipped with hoodle, and wherein the hoodle of a side is arranged on the bottom of key slotted eye, and the hoodle of opposite side is fixed on the lock gall by a back-moving spring.
The gate inhibition that the front end of described key slotted eye is provided with a shielding lock key trough hole locks pearl.
The utility model compared with prior art has the following advantages:
The utility model is owing to be provided with the lock pin groove of placement lock pin on lock gall to direction along the axis of lock gall, lock pin is elongated and be installed in the lock pin groove, tail end-side at lock gall is provided with the fully moving device that coaxial line is installed, on fully moving device, be provided with and the corresponding recess of lock pin, be provided with at interval between the tail end of lock gall and the fully moving device, fix in the lock pin groove by latch lock when lock pin is static, Lock Lee is connected and is equipped with on the moving device, that is to say that lock core is when normality, lock gall separates with fully moving device, therefore external force rotational lock core by force, lock core also is idle running, but does not destroy lock core, also can't open lock.
In a word, the utility model (1) lock core is provided with double-layer structure, so firm in structure. can bear stronger destruction test; (2) inserting key makes the lock core unlatching make lock core all need not lock gall is forwarded on the same point with transfering to key, can make arbitrarily angled group of spoon, the lawless person is difficult for cracking, and when lock core becomes idle running when key is transferred at once, rotates lock gall by force and whole lock core also can not be destroyed; (3) during technical unlocking, because key troughed belt gate inhibition when locking pearl, just can not look at key groove inner case straight, difficulty strengthens, special tool enters key groove inherence when not triggering the gate inhibition and locking pearl, just can not move in the key groove, can reach anti-omnipotent key and special tool and open.
