Abstract

The utility model relates to a padlock protector which solves the technical problem of being capable of making a stand-alone protecting lock sleeve without changing any part of the padlock. A padlock-shaped front cap iron with a narrow upper part as well as a wide lower part and the lock body portion of a back cap iron with a front in a shape like the Chinese character 'tu' are welded into a hollow lock sleeve. The upper part of the back cap iron passes through between two holes of the lock posts and is welded on the front cap iron after being bent into ninety degrees. The support piece of a lock beam is welded at both sides of the upper part of the back cap iron. Block irons and shoulder protectors are welded at both sides of the lock beam portion of front cap iron and both sides of the upper part of the lock body portion respectively. When a padlock is sheathed with the padlock protector, the upper part of the lock body is naturally hung on the lock body, and the padlock can be prevented from destroying, such as prying, smashing and filing, etc.

Description

Padlock protector

The utility model relates to a kind of padlock protector that is placed in the padlock outside.

It is more extensive that present all kinds of padlock uses, and easily pried open but also exist the space that utilizes between lock bridge and lock body, and easy-to-use file is filed the deadly defect that the lock pellet shot from a slingshot destroys lock.People have found out and have much protected the lock way for this reason, be called " Safety padlock " as name, application number is a locking mechanism of having loaded onto the fixedly pick-proof sliding sleeve of being made up of lock pin and spring after holing respectively from the both sides of lock body in the utility model application of CN85200679V, when the pick-proof sliding sleeve is sleeved on the lock body outside, during the padlock locking, under the promotion of lock bridge column Dou face, two lock pins stretch out the lock body outside, inserting respectively in the lock hole of pick-proof sliding sleeve both sides makes sliding sleeve be fixed on the lock body outside, reach with sliding sleeve and encase lock bridge and lock body, thereby prevent to lock the purpose that son is prized.This protector is good; played positive effect; simultaneously; this protector adds some additional mechanism providing additional operations on lock body and lock bridge bottom processing Dou face is finished; on the manufacturing process of lock body and lock bridge, increase new operation so undoubtedly and increased lock pin and spring, finally improved the manufacturing cost of padlock.

The purpose of this utility model is, any position of not changing the lock body lock bridge is provided, and can cover the space that lock bridge and lock body form, and can directly be sleeved on a kind of padlock protector of the outside pick-proof of lock body, anti-file.

The technical solution of the utility model is, the padlock protector is by the hollow lock tube that protects that is welded with the steel plate or the high-strength steel sheet of 2 millimeters thick of part in addition such as preceding break iron 2, back break iron 1, lock body shoulder protector 3, buting iron 4, lock bridge rest pad 5, stifled iron plate 6.Preceding break iron 2 is up-narrow and down-wide padlock shape integral plate, its lock body part both sides curve garden arc or squarely and therebetween the position be drilled with keyhole, top, both sides is welded with two lock body shoulder protectors 3 respectively or strikes out garden arc shoulder protector, its root and lock bridge contact site are the garden arc, the top edge of lock bridge part is that garden arc, both sides curve the garden arc or weld two buting iron 4 and are the garden arc, and its underpart links to each other with lock body shoulder protector 3, dug padlock beam usefulness breach 7 on the medial side of top edge.The front of back break iron 1 is a convex shape, its top and lock body corresponding height place curve after 90 ° and are welded into one with it through the inside that extends to preceding break iron 2 between two lock cylinder aperture, leave with positive both sides at an upper portion thereof and wear the lock bridge neutral gear, the both sides, bottom are welded into one with the both sides of preceding break iron 2 respectively.Between two lockholes in both sides,, just in time live lock bridge at an upper portion thereof from bottom supporting Yi Bian break iron 2 is welded with two lock bridge rest pads 5 that top has the garden arc respectively before leaning against.The extending part, top of two grooves between two buting iron 4 and two lock bridge rest pads 5 has welded two stifled iron plates 6, its rear end and lock bridge contact site have one with the corresponding garden of lock bridge diameter arc.

Advantage of the present utility model is that therefore any position that does not change padlock does not increase the manufacturing cost of padlock with regard to fertile stand-alone product.Be sleeved on during use on the padlock to pin with padlock and get, prevent from effectively to be prized, pound, destruction such as file, the time spent does not unblank just can take off or hang on lock.The utility model is simple in structure, be skillfully constructed, in light weight, intensity is high, easy to use.

The implementation detail of padlock protector is described in detail in detail below in conjunction with Fig. 1.The padlock protector comprises preceding break iron 2, and parts such as back break iron 1, buting iron 4, lock bridge supporting 5, lock body shoulder protector 3, stifled iron plate 6 are hollow lock tubes that the steel plate by 2 millimeters thick is welded.The up-narrow and down-wide padlock shape integral plate that preceding break iron 2 partly is made up of lock body part and lock bridge, for curving garden arc or square with the match both sides of its lock body part of lock body, top is welded with two lock body shoulder protectors 3 respectively, or strike out garden arc shoulder protector, its root and lock bridge contact site have one with the corresponding garden of lock bridge diameter arc.When padlock is laterally opened, bore a keyhole in one side and padlock corresponding height place, the top edge of lock bridge part is the garden arc, dug padlock beam breach 7 therebetween on the limit, be the space that produces between the lock bridge part of blocking lock bridge and preceding break iron 1, the both sides of lock bridge part curve the garden arc or weld two buting iron 4 and are the garden arc, and its underpart is connected with lock body shoulder protector 3.The front of back break iron 1 is a convex shape, its top and lock body corresponding height place curve after 90 ° and are welded into one with it through the inside that extends to preceding break iron 2 between two lock cylinder aperture, leave with the both sides in front at an upper portion thereof and pass the lock bridge neutral gear, the both sides, bottom are welded into one with the both sides of preceding break iron 2 respectively.At an upper portion thereof between two lock cylinder aperture in both sides, on one side the inside of forward break iron 2 be welded with two lock bridge rest pads 5 that top has the arc of corresponding garden with lock bridge respectively, just in time live lock bridge from bottom supporting.Form two sulculuses respectively between two buting iron 4 and two lock bridge rest pads 5, the extending part has welded two stifled iron plates 6 respectively at an upper portion thereof, and its rear end and lock bridge contact site are made and the corresponding garden of lock bridge radius arc.

When padlock protector cover 7 is contained in padlock; the top of back break iron 1 surrounds lock body from vertical centre; hanging on the lock body of nature; two lock body shoulder protector 3 upper shields are at lock body two upper lateral parts simultaneously; from the neutral gear of both sides, break iron 1 top, back, can see the corresponding site of lock body; one side of lock bridge is close to and has covered buting iron 4 on the buting iron 4, does not stay any space.

During lock body protector suit padlock, earlier the bottom neutral gear of lock bridge from the padlock protector pierced into, wear out from any neutral gear of both sides, break iron 1 top, back, lock body is just put thereupon.

Be the minimizing welding times when manufacturing, back break iron 1 except that lock bridge supporting 5, before break iron 2 the two break iron welding in front and back are got final product after comprising its two sides and lock body shoulder protector 3, the whole steel plate special drawing of buting iron 4 usefulness, also can separately and exclusively make welding forming afterwards according to condition lock body shoulder protector 3 and buting iron 4.
