Abstract

The utility model discloses a keyhole dustproof device for a U-shaped padlock. The keyhole dustproof device comprises a shell, a keyhole, a slide groove of a convex clamping position of a push plate, a guide groove of the push plate, positioning convex points, the push plate, the convex clamping position and positioning convex point holes. The shell is provided with the keyhole connected with the slide groove of the convex clamping position of the push plate, an inner cavity of the shell is provided with the guide groove of the push plate and the positioning convex points, the push plate is provided with the convex clamping position and the positioning convex point holes and mounted in the inner cavity of the shell, and the convex clamping position of the push plate is matched with the lock hole of the shell, the slide groove of the convex clamping position of the push plate, the guide groove of the push plate, the positioning convex points and the positioning convex point holes. The keyhole dustproof device for the U-shaped padlock has the advantages that due to the facts that the push plate and the convex clamping position are arranged in the inner cavity of the shell and the keyhole is connected with the slide groove of the convex clamping position of the push plate and the guide groove of the push plate, the technical defect that the push plate of the shell is prone to shed is thoroughly overcome, dustproof effect of the push plate is improved, the push plate can slide freely for covering and uncovering when the keyhole dustproof device is used, and accuracy in positioning, convenience in use and simple structure are achieved.

Description

U-shaped padlock lockhole dust guard

Technical field

The utility model relates to a kind of U-shaped padlock lockhole dust guard, relates in particular to a kind of dustproof push pedal protective device of U-shaped padlock lockhole of metal padlock.

Background technology

At present; known U-shaped padlock lockhole protective device structure is made up of housing, push pedal, stopper slot, grab, positioning convex point, location shrinkage pool; push pedal is allocated in housing stopper slot; push pedal is arranged on above housing; utilize push pedal to slide and open, cover operation; but this lockhole protective device disadvantage that cover plate is arranged on above housing is that push pedal easily comes off, do not have the effect of protection lockhole, and application life is short.

summary of the invention

For caducous technical deficiency is held in the push pedal that overcomes existing U-shaped padlock lockhole dust guard, the utility model provides a kind of U-shaped padlock lockhole dust guard, this U-shaped padlock lockhole dust guard can not only come off by anti-thrust plate, and it is extremely simple to make structure become.

The purpose of this utility model is to provide a kind of U-shaped padlock lockhole dust guard, it is by housing, mortise lock hole, push pedal convex clip position chute, push pedal direction recess, positioning convex point, push pedal, convex clip position, positioning convex point hole composition, on housing, be provided with mortise lock hole and connect push pedal convex clip position chute, be provided with push pedal direction recess at housing inner chamber, positioning convex point, in push pedal, be provided with convex clip position, positioning convex point hole, described push pedal is assemblied in housing inner chamber, mortise lock hole on push pedal convex clip position and housing, push pedal convex clip position chute, push pedal direction recess, positioning convex point, match in positioning convex point hole, expose higher than housing convex clip position, when it uses, push pedal is opened, cover the accurate positioning freely of sliding, the U-shaped padlock lockhole dust guard of this set, push pedal on housing forever can not be come off, improve push pedal dust-proof effect, greatly improve application life, and safety system causes also greatly raising, reach long service life, the object that safety factor is high.

The beneficial effects of the utility model are that push pedal, convex clip position are arranged and be fitted in connection push pedal convex clip position, housing inner chamber mortise lock hole chute, push pedal direction recess, thoroughly like this solve push pedal on housing and held caducous technical deficiency, improve push pedal dust-proof effect, when use, push pedal is opened, is covered the accurate positioning freely, easy to use of sliding, simple in structure.
