Stealing-opening-preventing buckle

Abstract

The invention discloses a stealing-opening-preventing. The stealing-opening-preventing is provided with a handle part, a limiting part and a positioning part; the handle part is provided with an inserting structure, the limiting part is provided with a limiting hole, a tearing structure and a limiting body, and the positioning part is provided with a through hole and a positioning body; and the stealing-opening-preventing is set to be under a locked state, the positioning part is folded relative to the limiting part, the positioning body is inserted into the limiting hole to limit the limitingbody to act, the handle part is folded relative to the limiting part to enable the positioning part to be located between the limiting part and the handle part, and the inserting structure is inserted into the tearing structure through the through hole. The stealing-opening-preventing cannot be recovered after being destroyed, and visual inspection finding can be facilitated.

Description

technical field [0001] The invention relates to a lock buckle, in particular to an anti-tampering lock buckle. Background technique [0002] There are various types of disposable locks currently on the market, and the general purpose is to connect two or more parts (products) through locks to achieve effects such as fixing and locking. [0003] Some of these locks also play an anti-theft effect. For example, the Chinese utility model patent ZL99237860 is used as a lock for a box cover. The lock is inserted into the box, and the box and the cover are connected together through the lock. It is necessary to destroy the lock during operation to open the cover, so it has an anti-theft effect. However, after the lock is broken, the torn material will fall into the box, which is not environmentally friendly and difficult to recycle, and its application range is limited. [0004] Chinese invention patent ZL200910042099 discloses another buckle, the structure of which is to snap in...

Problems solved by technology

And after unlocking, it can be assembled back again, which makes it difficult to find out whether the anti-theft buckle has been unlocked by visual inspection.

[0006] Therefore, there is a need for a novel one-time tamper-proof lock, which can not only meet the functions of fixing and locking, but also be damaged irreversibly when the box (boxed content) is opened, and its outer surface (Structural form) has obvious changes, and the friction force (other resistance) after assembly cannot be used to restore it
