The utility model is characterized in that the dialing lock shaft is arranged in the center of the lock body; a dialing spring, a compression spring and a spring cover are orderly arranged in an oblong hole at one side of the lock body; the spring cover is pressed by a fixing sheet; spiral dialing teeth and resetting keys corresponding to the spiral dialing teeth are arranged on the dialing lock shaft; a dial disc surface with digital is arranged at one end of the lock body; the dialing lock shaft is fixed on the lock body through the fixing plate and the fixing screws. The built-in lock can change number by turning the direction of the spring; a key is rotated for driving the spiral dialing teeth on the lock shaft to push the dialing spring to align to the number.

Description

Numerical ciphers built-in lock tapered end

The utility model relates to a kind of lock, specifically numerical ciphers built-in lock tapered end.

At present, the built-in lock of selling on the market, because the built-in lock spring adds the function that is provided with check mark less, who has the key of this lock to unblank, safety factor is poor.

The purpose of this utility model is, develop a kind of reasonable in design, increase snap, numerical ciphers dish, have check mark function, numerical ciphers built-in lock tapered end that safety factor is big.

Major technique content of the present utility model is, numerical ciphers built-in lock tapered end, by tapered end, the dialing lock shaft, the compression spring, the dialing spring, the axle spring, spring cup, stator, back-up ring, brace, retainer plate, fixed head, fixed screw constitutes, it is characterized in that, at the tapered end center, the dialing lock shaft is set, side at tapered end is provided with some oblong aperture, in each oblong aperture, put into the dialing spring successively, the compression spring, spring cup, with stator spring cup is pushed down then, be provided with spirality dialing tooth and playback key corresponding with it on the dialing lock shaft, the dialing spring is an isosceles trapezoid, it is corresponding with it that the axle spring is stairstepping, at tapered end one end, be provided with a band number scale disc surface, in disc face, establish a ring washer, rear end at the dialing lock shaft, brace is inserted gap, overlap a retainer plate, by fixed screw the dialing lock shaft is fixed on the tapered end with fixed head.When unblanking, key is inserted the dialing lock shaft clockwise rotate to 228 ° of angles.At this moment, each dialing spring is at the left end of spirality dialing tooth, and then, the spirality dialing tooth that rotates counterclockwise the dialing lock shaft is allocated to right-hand member to each dialing spring, at this moment, need not check the number and can unblank.When closing locking, do not clockwise rotate and must check the number.

The utility model is compared the advanced part that is had and is with prior art, numerical ciphers built-in lock tapered end has characteristics such as strengthening lockset safety and confidentiality, thereby has overcome weak point such as existing lockset safety factor difference.
