Description

Anti-theft lock and associated key
Technical field
The utility model relates to a kind of anti-theft lock and associated key.
Background technology
The lock cylinder of Shi Yonging all is single pellet shot from a slingshot up and down of branch or the above billiards structure up and down of two rows in the market, and the lock core of this structure all is to push up to corresponding position from the outside spindle direction of pellet shot from a slingshot in the lock core rotor, reaches the purpose that lock core is opened.The lock core of these structures also has bigger space at the place, tip of lock keyhole pellet shot from a slingshot, easily enter the unlatching lock core with unlocking tool, this in addition lock core spindle front end is provided with step, illegal opener is with drawing tool easily the lock core assembly can be pulled out, stir lockset and illegal the unlatching, use very dangerous.
Summary of the invention
The purpose of this utility model is to provide a kind of can overcome the defective that exists with upper lock core, and safe and convenient to use, a kind of anti-theft lock simple in structure and associated key.
The technical solution of the utility model is achieved in that a kind of anti-theft lock and associated key, it comprises column type lock core spindle, rotor, decoration ring, drive link, fixed head, adjust screw, hold-down screw, snap ring and associated key, in lock core, be provided with the A pellet shot from a slingshot that two rows are corresponding and misplace, the B pellet shot from a slingshot, end at the A pellet shot from a slingshot is provided with big spring, end at the B pellet shot from a slingshot is provided with little spring, end in addition at big spring and little spring is provided with jam, in column type lock core spindle, be provided with positioning ball, end at column type lock core spindle is provided with decoration ring, and end is provided with fixed head in addition.The center line in the front of the key that matches with lock core is provided with key bit, is provided with the pellet shot from a slingshot hole on the center line at the key back side, and keyhole is mountain type or selenodont.
The utility model has the advantages that: design is unique, and simple in structure, cost of production is low, can produce on traditional production technology basis, and is safe in utilization.

The specific embodiment
Shown in Fig. 1-7, a kind of anti-theft lock and associated key, it comprises column type lock core spindle 2, rotor 3, decoration ring 1, drive link 4, fixed head 5, adjust screw 6, hold-down screw 7, snap ring 9 and associated key 15, in lock core, be provided with the A pellet shot from a slingshot 10 that two rows are corresponding and misplace, B pellet shot from a slingshot 11, end at A pellet shot from a slingshot 10 is provided with big spring 12, end at B pellet shot from a slingshot 11 is provided with little spring 13, end in addition at big spring 12 and little spring 13 is provided with jam 8, in column type lock core spindle 2, be provided with positioning ball 14, end at column type lock core spindle 2 is provided with decoration ring 1, and end is provided with fixed head 5 in addition.Shown in Fig. 2,3,6,7, the center line in the front of the key 15 that matches with lock core is provided with key bit 16, is provided with pellet shot from a slingshot hole 17 on the center line at key 15 back sides, and keyhole 18 is mountain type or selenodont.
The utility model lock core spindle 2 external Design become column type, can prevent that illegal opener is with drawing tool that lock core is pulled out.As Fig. 1, shown in 5, because of being located at the A pellet shot from a slingshot 10 in the lock core rotor 3,11 their dislocation of B pellet shot from a slingshot are corresponding, because it is bigger than the tensile strength of little spring 13 to be installed in the big spring 12 of A pellet shot from a slingshot 10 and B pellet shot from a slingshot 11 rear ends, make a little less than elastic force the last one one of two springs, when lock core in when locking, be subjected to the influence of spring power, the last pellet shot from a slingshot of A pellet shot from a slingshot 10 is gone into rotor 3 in the length of setting by the different depth bolt, and B pellet shot from a slingshot 11 is by 10 pairs of pressures of A pellet shot from a slingshot, also different depth ground presses bolt to go into lock core spindle 2, row's pellet shot from a slingshot head dislocation this moments two is harmonious, head is positioned at back, key hole and forms a coaxial curve, gap between the keyhole 18 is minimum, constitutes the lock core inside and outside locking of pellet shot from a slingshot up and down, thereby can avoid special tool to stir pellet shot from a slingshot and open lockset.
When key 15 insertion keyholes 18 put in place, as shown in Figure 5, the key bit 16 of key 15 positive setting heights, A pellet shot from a slingshot 10 is pushed up to the line of demarcation of lock core spindle 2 and rotor 3, at this moment, be subjected to the effect of little spring 13, B pellet shot from a slingshot 11 will be got back to respectively in the hole in pellet shot from a slingshot hole, key 15 back side 17 simultaneously, thereby A pellet shot from a slingshot 10 and B pellet shot from a slingshot 11 are in respectively in lock core spindle 2 and the rotor 3 separately together with pellet shot from a slingshot up and down, constitute opening.
