Abstract

The utility model discloses a rotary number lock, which comprises an outer shell and an inner shell that are connected together, and a lock hook. The inner and the outer shells are internally provided with slide blocks which contact the spring and are excavated with numeral wheel axle holes. The numeral wheel axle holes are connected with the inner shell through the numeral wheel holes and are opened with notches; while the edges of the numeral wheel holes are provided with lock opening bolts. The end surface of the outer shell is opened with hole and the numeral wheel passes through the hole on the end surface of the outer shell; the end of the slide block is provided with a handle which passes through the handle slide hole on the end surface of the outer shell; besides, the slide block is provided with a bolt that is connected with the lock hook. The lock, by rotating the numeral wheel passing through the outer shell, opens the coded lock with password; compared with the prior pull-type coded lock, the utility model cancels a group of pulling wheels, providing comparatively simple and compact structure, so that the utility model is applicable for the diaries, albums and stamp alums, which are in different thickness.

Description

The rotation combination padlock

Technical field

The utility model belongs to coded lock, is specifically related to a kind of rotation combination padlock.

Technical background

Mostly lock on the A Diary with a Lock is the lock of band key at present, easily key is lost when the student uses, and has digital coded lock password number in sales process and also loses easily, makes troubles to use.Various coded locks are arranged on the market, be mostly that thumb wheel realizes unblanking by being stirred, it comprises number theory and two groups of wheels of thumb wheel, on the structure more than one group of wheel.

Summary of the invention

The purpose of this utility model is to provide a kind of rotation combination padlock of twisting with hand, to overcome above-mentioned defective of stirring combination padlock.

The utility model is achieved in that the rotation combination padlock comprises continuous shell and inner casing, latch hook, and shell is connected with lock side contiguous block.Be provided with slide block in the inside and outside shell, slide block contacts with spring.Open several axle holes on the slide block, the number wheel shaft passes number wheel hole and is connected with inner casing, offers notch on the number wheel shaft, and the bolt of unblanking is established at number axle hole edge.The perforate of shell end face, number wheel pass the shell end face, and the slider end limit is established handle and passed handle sliding eye on the shell end face, establishes dead bolt on the slide block and is connected with latch hook.This lock is taken turns by the number that rotation passes shell, and password is opened coded lock, the few one group of thumb wheel of structurally existing dial type coded lock, and structure is relatively simply compact.The diary, photograph album, the stamp album that can be used for different-thickness.
