Abstract
The utility model belongs to the technical field of the tool to lock. It completely contains the lock body, and is tightly fixed with the lock body into a whole body by means of its radial screw or rivet hole, and its rear end portion is equipped with screw thread or other connecting structure directly connected with lock body. The utility model discloses simple structure, the appearance is pleasing to the eye. The safety protection performance of the mortise lock head can be comprehensively improved by using the mortise lock.
Description
The utility model belongs to lock technology field.
General inserting-core lock is all used the metallic copper manufacturing, and its shortcoming is that anti-pounding resists the security performance of boring anti-sled relatively poor.For this reason, Chinese patent ZL94238786.4 has designed a kind of tapered end cover, and promptly at the protective jacket of a steel of tapered end leading section suit, so just having strengthened the tapered end leading section greatly is the outside survivability of lock pin lock.Yet the copper screw thread at tapered end rear portion is fragile, and relatively poor with joint efforts with the johning knot of steel lock body screw thread, thereby the defective of its anti-sled poor performance is also unresolved.
The purpose of this utility model is for the lock pin lock provides a kind of novel safety protection jacket, thereby improves its anti-capability and performance of pounding, resisting brill, anti-sled comprehensively.
The technical solution that realizes above-mentioned purpose is: former tapered end cover is carried out technological improvement, promptly prolong its pipe box part, make pipe box all contain to live tapered end, and closely being fixed into one by its radial screw or rivet hole and tapered end, portion offers screw thread or other syndeton that is connected with lock body in its back-end.
Accompanying drawing is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
This tapered end cover adopts high-quality steel one to shape, and handles through heat treatment and chromium plating, and intensity is good, and the hardness height is specious.Circle headgear (4) is gone up and is offered key hole (5) according to the position of lock core, and pipe box (2) is gone up uniform three radial screw holes or the rivet hole (3) offered, and rearward end car system connects the screw thread (1) of lock body.This steel screw thread (1) intensity height is strong with the adhesion that is threaded on the steel lock body.But, can between lock body and tapered end cover, set up dog screw, so on the outer wall of pipe box (2), offer dog screw pivot slot (6) in order further to strengthen lock body and being connected that tapered end overlaps.
The utility model is simple in structure, good looking appearance.Use that anti-that it can improve inserting-core lock comprehensively pounded, anti-ly bored, anti-sled performance.
Claims (2)
1, a kind of safety lock headgear, constitute one by circle headgear (4) that offers key hole (5) and the pipe box (2) that offers radial screw or rivet hole (3), it is characterized in that pipe box (2) all contains to live tapered end, be fixed into one by radial screw or rivet hole (3) with tapered end, portion offers screw thread (1) or other syndeton that is connected with lock body in its back-end.
2,, it is characterized in that also being provided with on pipe box (2) outer tube wall dog screw pivot slot (6) of lock body and tapered end cover by the described safety lock headgear of claim 1.
