Description

The padlock of water proof and dust proof

The utility model relates to padlock, belongs to the padlock of water proof and dust proof.

Padlock is common bright lock commonly used, and price is low, and is easy to use, can carry, and is used on door, the case more.The padlock that has is in the open-air atmosphere of extraneous wind and weather for a long time, and enter easily rainwater and dust of porose part adds the weathering and the oxidation that are subjected to nature on the lock body, gets rusty easily after permanent, makes lock malfunctioning, and open difficult pass; Even inject lubricated grease, because dust enters lock core and amasss into greasy filth, also easy-clear not; Especially be located in cold district, temperature is low can to make greasy filth solidify, and makes lock become " deadlock ".At present, enter in the padlock in order to prevent rainwater and dust, at the short pipe of lock nostril place weldering one band valve, lock body but influences outward appearance in pipe, and some is locked nose place and also is difficult for adding.

The purpose of this utility model is to overcome the shortcoming in the above-mentioned present technology, and a kind of padlock that self has water proof and dust proof is provided.

The purpose of this utility model can reach by the following technical programs: on the two ends of lock ring sealing ring pad is housed, can prevents that rainwater from entering lock body.The flat board that studs with corresponding shape on the lock body side of keyhole with screw is arranged, the sliding eye corresponding with keyhole arranged on the plate, boring is arranged in a side of sliding eye; Be equipped with the slide block of sealing keyhole in the sliding eye, the cylinder that stretches into above-mentioned boring is arranged on the slide block, be with spring on the cylinder.Stir slide block and can expose keyhole, after key takes out, the slide block capping keyhole that under spring action, can reset, thus can realize the design's purpose.

The utility model is compared with above-mentioned prior art can have following effect: owing at the two ends of lock ring sealing mat is housed; in that the office of on the lock body side of keyhole sealed key hole being housed is arranged, can prevent entering of rainwater and dust, lock there is protective effect; lock leaves flexibly, the convenient use.

Accompanying drawing 3,4th, Fig. 1,2 have the front view that studs with surface plate 8 sealed key hole states on the side of keyhole;

Accompanying drawing 5 is Fig. 3, and the axle of surface plate 8 is surveyed diagrammatic sketch on 4;

Accompanying drawing 6 is Fig. 3, the axonometric drawing of 4 top shoes 7;

Accompanying drawing 7 is Fig. 3, studs with the axonometric drawing of cover plate 6 on 4 again;

Accompanying drawing 8 is axonometric drawings that valve 4 can be housed on Fig. 7 slideway 5.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

In conjunction with shown in Figure 3, semicircle lock ring 3 and keyhole are arranged on the lock body by accompanying drawing 1.The joint ring (1,2) that lock back and lock body close proximity are touched is housed on the two ends of lock ring 3, helps the sealing at two places on the lock body.Have on the lock body side of keyhole to stud with surface plate 8, have the sliding eye 9 that exposes keyhole on the plate 8, boring 10 is arranged in a side of sliding eye 9 with screw.Sliding eye is equipped with the slide blocks 7 that dovetail groove assembles for 9 li, and the cylinder 12 of boring stretched into 10 is arranged on the slide block 7, is with spring 13 on the cylinder 12.

Can push away the convex body 11 of pulling on the above-mentioned slide block 7, make things convenient for sliding slider 7,, can make surface plate 8 be two parts, tumble in wherein a part of surface plate with screw earlier, load onto slide block 7, tumble in another facial planes plate 7 with screw again for making things convenient for being bumped into of slide block 7.If for facing the angle assembling directly, surface plate 8 can be an integral body to slide block 79 li of sliding eyes, but like this will be on the surface plate 8 that slide block 7 and spring 13 are housed insert cover clamp 6, in case the deviating from of limited slip block 7, and have the slideway 5 of convex body 11 on the plate 6, as shown in Figure 7; Valve 4 with the dovetail groove assembling can be housed on the slideway 5.Boring (groove) be 2,2 cylinders 12 are also arranged on the slide block 7, but in sliding process smooth sliding.There is the lock body side of keyhole to want level and smooth, helps the slip of slide block 7.Earlier valve is shifted onto one during use, push away the convex body 11 of pulling again with left hand and make cylinder 12 compression springs on the slide block 7, at this moment keyhole exposes on the lock body, and the right hand is held the key insertion and unblanked, and opens the back and takes out key, and slide block 7 resets and sealed key hole under the effect of spring 13.
