Description
Technical Field
The utility model relates to a tool to lock especially relates to a sheath lock.
Background
Referring to fig. 1-2, a prior art sheath lock has a lock case 10 'with a jacket installation hole 12' formed on one end surface of the lock case 10 ', a jacket 22' inserted into the jacket installation hole 12 'from the outside of the lock case 10', a lock cylinder 24 'inserted into the jacket 22', and a cover 26 'fitted over the lock cylinder 24'. The lock casing 22 ' is fixed in the lock case 10 ' by means of screws by providing through holes in the inner wall 14 ', and the cover 26 ' is fixed in the lock case 10 ' by means of screws by providing through holes in the outer wall of the lock case 10 ' opposite to the inner wall 14 '. A bolt hole (not shown) is transversely formed in the rear wall 16 ', and when the key 36' is inserted into the lock cylinder 24 'and rotated by a certain angle, the lock rod 40' and the bolt located in the bolt hole are mutually clamped, thereby achieving the purpose of locking. Meanwhile, the edge sealing cover 26' is provided with a drilling hole (not numbered) for preventing illegal persons from directly damaging the lock cylinder by means of tools such as an electric drill and the like, so that violent unlocking is realized.
Meanwhile, after the edge sealing cover 26 'is fixed on the lock shell 10' by penetrating the outer wall through a screw, a manufacturer welds and blocks a through hole for the screw to penetrate through on the outer wall, polishes the outer wall, thereby eliminating welding marks as much as possible, preventing an illegal person from drilling the blocked through hole through a tool, then detaches the screw through a screwdriver, and then easily detaches the edge sealing cover from the lock sleeve mounting hole, finally destroys the lock core through a tool such as an electric drill, and achieves the purpose of forced unlocking.
However, the above sheath lock has the following problems:
firstly, because the edge sealing cover is directly installed in the lock sleeve installation hole from the outside of the lock shell and is fixed on the lock shell by penetrating through one outer wall of the lock shell through a screw, even if a manufacturer polishes the outer wall, the color of the polished part is always slightly different from the rest colors, even if electroplating and painting are carried out on the whole outside of the lock shell, illegal personnel can still easily find the polished part and drill the through hole to realize violent unlocking, and therefore the safety of the traditional jacket lock is poor.
Secondly, the prior sheath lock is provided with a through hole on the inner wall, and the lock sleeve is fixed on the lock shell by a screw. The screw is screwed from the inner wall of the lock shell, so the operation space is very narrow, and the operation process can be only manually operated by means of tools. This greatly reduces the assembly efficiency of the sheath lock, resulting in a significant increase in production costs.
Therefore, there is a need for an improved sheath lock that overcomes the above-mentioned drawbacks, increases safety, reduces production costs, and improves assembly efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a sheath lock, its greatly increased the degree of difficulty that violence unblanked, strengthened the security to the packaging efficiency is high.
In order to achieve the above object, the present invention provides the following technical solutions:
