Abstract

The novel plastic lock seal solves the problem of that the lock seal before locking is easy to be regulated by a person to change its property, which comprises a plastic housing and a insertion piece inserted in the housing in which a core body is provided, at two sides of the housing interior is provided respectively with an elastic hook, on the insertion piece are provided in parallel with a bayonet I and a bayonet II both of them can clasp the said elastic hook, the housing is provided with two threading holes thoroughly through up to down, and the insertion piece is provided with through holes corresponding to the threading holes. Advantage: it can not be regulated before it is locked, and it can not be opened once it is locked, so it is safety and reliable.

Description

technical field [0001] The invention relates to a lock used for sealing off electric metering facilities or other facilities, in particular to a new type of self-locking plastic seal. Background technique [0002] At present, in the field of sealing of electrical metering equipment, the one-time self-locking sealing has better anti-counterfeiting effect than the original lead seal, and thus has been widely used. The generally used disposable self-locking seal includes a plastic shell and an insert inserted into the shell. The insert is provided with elastic barbs, and the inner wall of the plastic shell has steps for the elastic barbs to be stuck. cannot be pulled out backwards due to the obstruction. However, the elastic barbs arranged on the plug-in are artificially adjusted by using the gap between the plug-in and the casing before the lock is completely closed, which reduces the safety performance of the lock. Contents of the invention [0003] In order to overcome t...
