Abstract

The utility model relates to a waterproof dustproof padlock which is composed of a lock body, a lock core and a hanger, wherein the lock body is provided with a keyhole and two hanger insert holes. The utility model is characterized in that both ends of the hanger are provided with annular inner pits corresponding to the maximum stroke points of the insert holes of the lock body, and the annular inner pits are sheathed with sealing rings. When the padlock is locked, the sealing rings sheathed on the annular inner pits on both ends of the hanger just shield the insert holes on the lock body so as to play the waterproof dustproof functions. The padlock has the advantages of simple structure, convenient operation and prolonged service life.

Description

The water proof and dust proof padlock

Technical field

The utility model relates to a kind of padlock, particularly a kind of water proof and dust proof padlock.

Background technology

Padlock is a kind of traditional, scope of application lockset widely, generally is made up of lock body, lock core, hangers, has a keyhole and two hangers patchholes on the lock body.Because the center of gravity of padlock is on lock body, therefore in use always lock body is following, and hangers is last, and hangers inserts two holes of lock body with regard to always up.Its shortcoming is: be used for outdoor padlock and very easily lived by rainwater, dust etch, rust, can't normally use.In order to prevent the padlock water inlet, there is the people outside padlock, to install protector additional, increase cost, and must open the state that protector could be checked lock, use inconvenience, poor stability.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of water proof and dust proof padlock simple in structure is provided.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of water proof and dust proof padlock, form by lock body, lock core, hangers, have a keyhole and two hangers patchholes on the lock body, the range place that it is characterized in that the corresponding lock body jack at the hangers two ends has the ring-type indent, and recess is with sealing ring in the ring-type.

The beneficial effects of the utility model are as follows: when this padlock pins, the sealing ring that is enclosed within recess in the ring-type of hangers two ends tightly shelters from its jack on lock body just, plays the effect of water proof and dust proof, and is simple in structure, easy to use, the application life of prolongation padlock.

Description of drawings

Fig. 1 is the utility model water proof and dust proof padlock overall structure schematic diagram (partial cutaway is shown).

Fig. 2 is the A-A schematic diagram of keyhole seal closure among Fig. 1.

The specific embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.

As shown in Figure 1, the utility model water proof and dust proof padlock, form by lock body 1, lock core (not drawing among the figure), hangers 2, have a keyhole 3 and two hangers patchholes 4 on the lock body 1, the range place that it is characterized in that the corresponding lock body jack at hangers 2 two ends has ring-type indent 21, and recess is with sealing ring 22 in the ring-type.

In embodiment as depicted in figs. 1 and 2, further feature is: 1, sealing ring 22 is made for elastomeric material, because hangers has a resilience by a small margin when locking, resilient sealing ring can guarantee the sealing after the resilience; 2, has one with soft material such as rubber, the keyhole seal closure 5 that plastics are made, seal closure 5 end faces have annular bead 51, has corresponding annular groove 31 on the lock body 1 of keyhole 3 peripheries, sealing cover 5 annular groove 31 by the annular bead 51 on it and keyhole 3 peripheries is joggle mutually, reach the purpose of tightly blocking keyhole, prevent that water droplet and dust from entering lock body by keyhole, also has the chain rope 6 that connects seal closure 5 and lock body 1, when opening seal closure and unblanking, seal closure is difficult for losing, after extracting key, again seal closure is covered on the keyhole, easy to use.

Claims
