Abstract

The present utility discloses an improved design of a lock device, which comprises a lock shell (1), a lock core (2) which is arranged in the lock shell and a key (4) corresponding with the lock core. A seizing groove (8) is arranged in the lock shell and a lock pin (5), a lock column (3) and a spring (6) are arranged in the lock core. The top of the lock core is cooperated with the seizing groove in the lock shell. The utility model is characterized by arranging a roller (7) in the lock core (2), and arranging a groove on the lock column. The bottom of the lock pin is V shaped, and the lock column is arranged on the two side of the lock pin. The angle between the vertical of the lock pin section and the center line of the two side of the lock column is alpha. The roller is cooperated to the groove and the roller on the two side of the lock pin is cooperated to the two inclined planes formed by the V shaped section on the lock pin bottom. The utility model changes the vertical placed lock column into an inclined placed lock column, thus realizes the locking and unlocking by the up and down moving of the lock pin caused by the rolling of the cooperated roller. The utility model is provided with a simple structure and the anti-theft performance is also greatly improved.

Description

A kind of lockset

Technical field: what the utility model was related is a kind of improvement invention of lockset.

Background technology: in the prior art, the structure of lockset is multifarious, various, but its main composition still is the key of lock core, lock housing, lock, lock pin and unlatching, and the most general lockset of present use, its lock all is a straight column type, just lock all is vertically disposed, the ccontaining lock in bigger space must be arranged in its lock core of the lockset of this kind structure, so have the square body of projection on the lock core, not only make and go up quite trouble, and owing to be the structure that generally adopts, so also there is deficiency in the safe antitheft performance.

Summary of the invention: in view of the existing deficiency of known technology, the technical problem that the utility model solved is in order to provide a kind of reasonable in design, and is simple in structure, a kind of lockset that theftproof performance is high.To achieve these goals, the utility model adopts following technical scheme to realize: this kind lockset, include lock housing, the key that is installed in the lock core in the lock housing and is complementary with lock core, be provided with draw-in groove in the described lock housing, be provided with lock pin in the described lock core, lock and spring, described spring contacts with the lock afterbody, draw-in groove in the top of described lock pin and the lock housing matches, it is characterized in that also being provided with in the described lock core roller, described lock is provided with groove, the bottom section of described lock pin is V-shaped, described lock branch is located at the both sides of lock pin, have angle respectively between the vertical line in described lock pin cross section and the center line of both sides lock, described roller matches with the groove of lock, and the roller of lock pin both sides and inclined-plane, lock pin bottom corresponding matching.The angle that forms between the vertical line in described lock pin cross section and the center line of both sides lock is respectively the 8-15 degree; Groove on the described lock is an annular groove.

The utility model is because vertically disposed lock that will be in the past changes into is obliquely installed, and cooperates the rolling of roller to realize moving up and down of lock pin and reach the purpose of the locking of unblanking.Simple in structure, and theftproof performance also improves greatly.The utility model compared with prior art has substantive distinguishing features and progress.

Description of drawings: the utility model has following accompanying drawing:

Structural representation when Fig. 1 unblanks for the utility model.

Structural representation when Fig. 2 is the utility model locking

The specific embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, further describes each relevant details and operating principle of embodiment below more in conjunction with the accompanying drawings.This lockset includes lock housing 1, the key 4 that is installed in the lock core 2 in the lock housing 1 and is complementary with lock core 2, be provided with draw-in groove in the described lock housing 1, be provided with key pin 5 in the described lock core 2, lock 3 and spring 6, described spring 6 contacts with the afterbody of lock 3, be provided with the groove of taking lock 3 and spring 6 in the described lock core, draw-in groove in the top of described lock pin 5 and the lock housing 1 matches, also be provided with roller 7 in the described lock core 2, described lock 3 is provided with annular groove, the bottom section of described lock pin 5 is V-shaped, described lock was located at the both sides of lock pin 5 in 3 minutes, the angle that has the 8-15 degree between the vertical line in described lock pin 5 cross sections and the center line of both sides lock 3 respectively, described roller 7 matches with the groove of lock 3, and inclined-plane, the left and right sides corresponding matching of roller 7 and the formation of lock pin 5 bottom chevron shaped cross sections.

When the utility model is unblanked, insert key 4, key 4 has overcome the elastic force of lock 3 upper springs 6, spring is oppressed, and key 4 can move up the lock 3 in the lock core 2, and drive roller 7 moves up, make the distance between center line elongation between two rollers 7, at this moment, the V-arrangement cross section of lock pin 5 will not have the frictional force of roller 7 gradually and has moved down, and makes lock pin 5 break away from the purpose that the draw-in groove realization is unblanked.

And when extracting key 4, the spring return of lock 3 upper springs 6, lock 3 can be pushed away downwards, and lock 3 can drive roller 7 simultaneously and move down and shorten distance between center line between two rollers 7, this will make roller 7 along inclined-plane, lock pin 5 bottom lock pin 5 upwards be pushed away, and makes lock pin 5 fall into the purpose that reaches locking in the draw-in groove of lock housing 1.

Claims (3)
