Abstract

The utility model relates to a functional improvement of a padlock. The utility model is characterized in that the outer surface of a lock body of the padlock is provided with a sealing layer sleeve, the root of a lock button is provided with a metal lining and a sealing ring, and a sealing cover and a seal plug are arranged on the bottom of a lock hole. The remarkable sealing effect of the padlock can efficiently prevent rainwater along the lock button from permeating a lock core of the padlock, and prevent the dust from going into the lock core from the bottom of the lock hole; therefore, the utility model prevents the lock body from rusting, and keeps unlocking convenient, and prolongs the service life of the padlock.

Description

Water and dust-proof padlock

The utility model relates to the improvement of padlock function, and its architectural feature is to be added with the sealant cover in the lock body outside of padlock, and the snap close root has metal lining and sealing ring, and there are seal cover and sealing-plug in lockhole place in bottom.

Seen in the market padlock, various in style, structure is different, but common defective be can not water proof and dust proof, only be adapted to indoor use, as using, then be subjected to dirt, water infiltration very soon and corrosion damages at outdoor open-air place.

The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of can waterproof, again can the dustproof padlock, can prevent corrosion effectively, increase the service life.

The purpose of this utility model can reach by following measure: the lock body outside at padlock is added with the sealant cover, and the snap close root has metal lining and sealing ring, and there are seal cover and sealing-plug in lockhole place in bottom.

The purpose of this utility model can also reach by following measure: the sealant cover of lock body outside is divided into and overlaps and two parts of trapping, and with concavo-convex interface close adhesion, interface also can be flat or oblique.The cover end face of going up of sealant cover has two holes that cooperate with the metal lining external diameter that can pass through snap close, and the bottom center that traps has one can be by the hole that cooperates with sealing-plug of key.Metal lining is to adopt for example circle of the short cylindrical shape made of copper or aluminium alloys of antifriction metal (AFM).Sealing ring on the snap close is with the rubber-like material elastic tape made of rubber for example, also can make with plastics.Seal cover one end of bottom links to each other with a side base of sealant cover, and there is handle at the back side of seal cover, and there is the chock plug of sealing-plug in the front.

The utility model compared with prior art has following advantage: because whole lock body makes the metal material of lock body not be exposed to the space with the sealing of sealant cover, the sticking infiltration of the unlikely dirt that is subjected to drenching with rain is got rusty.The snap close root has metal lining and sealing ring, closely wales around the snap close, and rainwater can not immerse lock core along snap close.There are seal cover and sealing-plug in lockhole place in the lock body bottom, lockhole can be sealed closely unlikely dust and the water droplet of entering.Therefore, dirt is not intake, do not advanced to the utility model in can guaranteeing that padlock uses for a long time in the open, keeps normally using, and solved because of corrosion causes the difficult problem of unblanking, and prolongs the application life of padlock greatly.

The drawing of the utility model accompanying drawing is described as follows:

Fig. 1 is the lateral view of water proof and dust proof padlock;

Fig. 2 is just (A-A) face sectional view of padlock;

Fig. 3 is seal cover (B-B) and sealing-plug sectional drawing;

Fig. 4 is that the metal lining structure reaches (C-C) sectional view;

The utility model is described in further detail to enumerate embodiment below in conjunction with accompanying drawing.

Water proof and dust proof padlock illustrated in figures 1 and 2, sealant cover (5) in lock body (1) coated outside, sealant cover (5) is divided into cover (5-1) and (5-2) two parts of trapping, last cover (5-1) is as a lid, trap (5-2) as base, middle with concavo-convex interface close adhesion, interface also can be flat or oblique.Last cover (5-1) end face has two can be by the hole that cooperates with metal lining (3) external diameter of snap close, and (5-2) bottom center that traps has one can be by the hole that cooperates with sealing-plug (7) of key.Root respectively is with a metal lining (3) and sealing ring (4) in snap close (2) both sides, metal lining (3) is short cylindrical shape as shown in Figure 4, can be with for example copper or the aluminium alloys manufacturing of wear-resisting and rustless metal, sealing ring (4) as shown in Figure 5, make an elastic tape with rubber, also can use plastic processing, closely be enclosed within snap close (2) root, prevent that rainwater and dust from infiltrating lock core.Be connected with a seal cover (6) on sealant cover (5) one side bases, a sealing-plug (7) is arranged on the seal cover (6), sealing-plug (7) is made of handle (7-1) and chock plug (7-2), handle (7-1) is at the back side of seal cover (6), handle (7-1) can be a ball, also can be circle, chock plug (7-2) cooperates jam-pack in the front of seal cover (6) with the lockhole that lock body (1) is gone up sealant cover (5), prevents the dust intrusion.

Claims

1, a kind of water proof and dust proof padlock that is made of lock body and snap close is characterized in that lock body (1) outside of padlock is added with sealant cover (5), and snap close (2) root has metal lining (3) and sealing ring (4), and there are seal cover (6) and sealing-plug (7) in lockhole place in bottom.
