Abstract

A chain key and a bend lock cylinder belong to locks, and particularly relate to novel design for a chain key and a bend lock cylinder. The chain key comprises a chain key handle (3), a chain key sleeve (2) and a chain key body (1); the chain key body (1) is arranged in the chain key sleeve (2); a through slot is arranged in the middle of a lateral surface of the chain key sleeve (2); and the chain key handle (3) is sleeved on the chain key sleeve (2) and connected with the chain key body (1) by the aid of a pin (23) arranged in the through slot of the chain key sleeve. The lock cylinder has a bend; bend traps (57 and 58) are arranged in the bend; drilling-resistant columns (55 and 56) and drilling-resistant sheets (51 and 52) are arranged on two sides of the bend; and a lower spring ball (41) of a lock spring is in a cross shape or cap shape (42). By the aid of the design, the chain key and the bend lock cylinder thoroughly solve the problem that existing lock design is easy for technical unlocking, eliminate worry of users, improve safety and benefit social safety and harmony.

Description

Chain spoon and bend lock core

Technical field

The utility model belongs to a kind of lockset, specifically is the new design of a kind of chain type key and bend lock core.

Background technology

Existing lockset kind is a lot, and the cooperation of key and lock generally is that straight plate key cooperates straight lock core road.The shortcoming and defect that exists is: the one, and the lock core straight way inserts the strong destructive lock of opening in back by hard thing easily; The 2nd, existing lock core pearl is that up and down pearl is straight-through, can by collude, choose, pneumatic gun is inflated or lock is opened in the technical back of backing down such as the glue that expands.Safe coefficient is firm inadequately, to the thief opportunity is arranged.

Summary of the invention

The purpose of this utility model is a kind of safer theftproof lock of design, be chain spoon and bend lock core, the chain spoon comprises chain the shank of the key, chain spoon cover and chain spoon body, chain spoon body is arranged in the chain spoon cover, chain spoon cover stage casing, side has groove, the chain the shank of the key is enclosed within above the chain spoon cover and by pin and is connected with chain spoon body, and pin is in the groove of chain spoon cover; Chain spoon body comprises more piece standard grain, a section header grain and one section tail grain, forms hinge by connection grain axle between each sections and connects.

Chain spoon cover front end is provided with 2 retainer spring sheets, and its effect is to play fixation after chain spoon cover inserts chain spoon trepanning.

Chain spoon and bend lock core, lock core is a bend, is provided with the bend trap in the bend, the both sides of bend are provided with anti-drill string.

The both sides of lock core bend are provided with anti-drilling sheet.

The lock core bend, wherein the lower pellet of snap is a cross, perhaps is covering cap shape, the operating range of hoodle in the snap road is limited.

With promoting the chain the shank of the key forward behind the chain spoon cover insertion lock core hole.The chain spoon promotes down to front slide, and pearl makes progress Zhu Ding and unblanks.Bullet can not prevent the technical unlocking lock fully by the position of lock core to last pearl under cross lock core lower pellet and the covering cap shape lock core pearl because of following pearl has.When chain lock enters by the bend lock core, other objects can not be entered smoothly because of the bend lock core is provided with 2 bend traps.When taking out the chain spoon,, make the chain spoon withdraw from lock core, finish the work by slide fastener the shank of the key backward.

The utility model is owing to taked above-mentioned design, the effect that has: by invention cross lower pellet or covering cap shape lower pellet, prevent with fixedly, skilled unlockings such as pneumatic gun, expansion glue.Trap in the bend is the trap of setting when preventing to enter bend and unblank with other objects outside the chain spoon, makes it to enter smoothly and can't open lock.Chain spoon cover front end is provided with 2 retainer spring sheets, and its effect is to play fixation after chain spoon cover inserts chain spoon trepanning.Thoroughly solve the problem of the easy skilled unlocking of existing lock design, eliminate user's worry, improve safety, help the social safety harmony.
