CN2436612Y - Drilling-resistant structure for lock core - Google Patents

Abstract

The utility model relates to a drilling-resistant structure for a lock core, which can avoid breakage from an exposed part of a lock core. The utility model is characterized in that a drilling-resistant shield which is made of hard steel is arranged at an exposed end face 11 of a lock core 1, the shield is sheathed at the outer margin of the end part of the lock core, and the shield is fixed by a pin 7. The drilling-resistant shield is fixed with a lock body 2 in an inlay way, and a key inlet 61 which corresponds to a key inlet arranged on the lock core is arranged on the drilling-resistant shield. The utility model can effectively prevent stealers from drilling the lock at any exposed part of the lock core, and therefore, the theftproof performance and the safe use performance of the lock can be improved. The service life of the lock can be prolonged.

Description

Lock core drilling-preventing structure

The utility model relates to a kind of theft-prevention structure of lock, particularly relates to a kind of lock core drilling-preventing structure of destroying from the exposed parts of lock core of preventing.

Lock is the article commonly used during people live, although the structure of lock is different, various informative, but most lock all has a lock core, we can say that it is the brain or the heart of lock, because the end face and the spoon inlet of the lock core of various locks all are exposed to the outside, and lock core is mostly made by the softer copper material of material, thereby become the primary destruction target of thief, also be the place that people should consider emphatically when designing theftproof lock certainly.Yet traditional lock core drilling-preventing structure just adds one to multiple anti-drilling steel nail in the cipher code set outside of lock core body, to play anti-drilling effect.But in fact because the lock core area that anti-drilling nail protected is limited, so anti-drilling effect also can only be local, especially exposed parts can not reuse owing to unshielded structure is difficult to avoid being damaged.

The utility model improves at the problems referred to above exactly, and its purpose is to provide a kind of whole exposed face that makes lock core all to obtain the lock core drilling-preventing structure that protects, and improving the theftproof performance of lock, and prolongs its application life.

For achieving the above object, the utility model provides a kind of lock core drilling-preventing structure, it is characterized in that being provided with an anti-drilling guard shield at the end face that exposes of lock core, have on this guard shield with lock core on the corresponding spoon inlet of spoon inlet.

Described anti-drilling guard shield is placed in lock core end outer rim, and by dowel fixes, and anti-drilling guard shield and lock body are inlayed fixing.

Described anti-drilling guard shield is made by the hard steel.

Drilling-preventing structure of the present utility model is applicable to various types of padlocks.

The utility model has been broken the anti-drilling pattern of traditional lock; by having added anti-drilling guard shield on the end face exposing of lock core; make anti-drilling area by the lock core of making than softwood matter by local expansion to the whole end face that exposes; thereby any exsertion part brill lock of person that do not avoid theft effectively from lock core; therefore can improve the theftproof performance and the safety in utilization of lock greatly; prolong the application life of lock, protection the people's lives and property safety.Characteristics such as the utility model also has simple in structure, implements easily, and is practical.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model three-dimensional exploded view.

Fig. 2 is a sectional view of the present utility model.

Consult Fig. 1, Fig. 2, padlock as shown in the figure comprises lock core 1, lock body 2, lock bridge 3, and wherein lock core 1 is made by copper material, and it is contained in the lock body 2, and fixing by stop screw 4, and one end-face 11 exposes.The lock core other end is connected with lock bridge 3 by pin 5.Main points of the present utility model are, be provided with an anti-drilling guard shield 6 outside the end face 11 exposing of lock core 1, this guard shield is shell-like, its shape is identical with the end surface shape of lock core, for both are connected firmly, process a ring-shaped step 12 in the lock core end face edge, the edge of guard shield is enclosed within this step place, and fixing by pin 7.The lock core that guard shield 6 is housed adopts stationary fit to be inlaid in the lock body again.On this guard shield with lock core on the spoon inlet corresponding section also have corresponding spoon inlet 61, can insert key through this spoon inlet.For making drill bit be difficult to pierce, above-mentioned guard shield adopts the hard steel, makes as mild steel.

Claims (3)

1, a kind of lock core drilling-preventing structure is characterized in that, is provided with an anti-drilling guard shield (6) outside the end face (11) exposing of lock core (1), have on this guard shield with lock core on the corresponding spoon inlet of spoon inlet (61).

2, lock core drilling-preventing structure according to claim 1 is characterized in that, described anti-drilling guard shield (6) is placed in lock core end outer rim, and fixing by pin (7), and anti-drilling guard shield and lock body (2) are inlayed fixing.
