Abstract

The utility model is an office furniture lock with ball bead type lock cylinder, comprising a key 1, a lock core 2, an inner lock cover 3, an upper outer cover 4, and a lower outer cover 5, a lock bolt 6. The utility model is characterized in that a solid cylinder 8 is arranged at the center of the lock core 2, and key positioning grooves 7 are provided at the edge of the lock core, and a zinc cover 9 with balls and a spring are installed surrounding the lock core; the key 1 is a hollow cylinder with teeth on, the teeth correspond to the alignment of the balls in the lock core 2. The balls of the office furniture lock with ball bead type lock cylinder can be aligned in many ways, and the probability of same-opening is only 0.0001 percent, and the utility model is of good safety performance; the solid lock core gives the furniture lock strong force-resistance and longer service time; meanwhile, the key of hollow cylinder type nests and rotates the balls to solve the problem of that the common lock core rotates inflexibly and the keys can not plugged or pulled smoothly.

Description

Ball bead type lock core office furniture lock

Technical field:

The utility model belongs to office furniture with locking.

Background technology:

Widely used office furniture is locked on the market now, be the lock core structure that adopts blade inserting mostly, because inserted sheet upper raised teeth quantity is insufficient, thereby cause shaped as key bit few, higher with opening rate, in addition because inserted sheet and lock core are on the point of numerous friction, thereby application life is not long, also have several ball bead type lock core office furniture locks in addition, as the cross key lock, the in-line key lock, their operating principles are basic identical, mainly by lock body, lock gall, spring, parts such as hoodle are formed, and hoodle is through to lock gall from lock body, and hoodle one end is exposed in the keyhole in the lock gall, in double wedge on the key outwards is pressed out to the hoodle of correspondence, the handing-over mouth of hoodle be in lock body and lock gall interface with in the one side, make hoodle lose control action to lock gall, key just can drive lock gall rotation lock gall and drive lock drawback lock mechanism action again, thereby a lock is opened; Under spring action, hoodle is stuck between lock body and lock gall during locking, and lock gall can not be rotated, and more than unblanking all is to drive lock gall by key to rotate, and lock gall drives unlocking mechanism again, and this mode of unblanking is complicated, and lock gall and unlocking mechanism rapid wear, and descend to application life.

Summary of the invention:

The purpose of this utility model provides a kind of theftproof performance ball bead type lock core office furniture lock strong, simple in structure, comprise key, lock core, inner lock shell, outward go up lock housing, descend lock housing, dead bolt outward, it is characterized in that: the lock core center is provided with solid lock core column, have the key positioner groove on the edge, periphery is equipped with the zinc cover of band pellet shot from a slingshot and spring, and dead bolt and solid lock core column are connected; Key is a hollow cylindrical, on be carved with tartar, the arrangement of pellet shot from a slingshot in the corresponding lock core of this tartar.

During use, by shown in Figure 2, pressing under the key insertion keyhole, pellet shot from a slingshot is embedded in the zinc cover that spring is housed, key turns clockwise, drive lock core column and rotate, dead bolt is rotation (referring to Fig. 1) synchronously thereupon also, reaches and opens lock, loose one's grip this moment, push up on the spring, the key that has locating slot just in time is stuck on the inner lock shell, reach the effect of location; Be rotated counterclockwise key, can realize closing locking, promptly key tooth flower is arranged with pellet shot from a slingshot, unblanks clockwise, shut counterclockwise,

Beneficial effect is: the spread pattern of pellet shot from a slingshot is many in this ball bead type lock core office furniture lock core lock core, with the rate of opening only be ten thousand/, it is much lower that this opens rate more than blade inserting lock core 3/1000ths same, increased antitheft coefficient, theftproof performance is strong; Solid lock core, the external force resistance ability is stronger, longer service life; The nested pellet shot from a slingshot of hollow cylindrical key makes it to rotate, and has solved common lock core and has rotated dumb, the slotting problem that has some setbacks of getting of key.

Description of drawings:

Fig. 1 is a kind of ball bead type lock core of the utility model office furniture lock and key side view.
