Description

A kind of padlock

Technical field

The utility model relates to a kind of lockset, relates in particular to a kind of padlock.

Background technology

Padlock is the antitheft articles for use that people use always, is made of lock body and lock bridge, and the U-shaped lock bridge is contained on the lock body, and keyhole is arranged on the bottom of lock body.In order to prevent that padlock from getting rusty, can be in lock body outside parcel plastics lock housing, parcel U-shaped plastic sheath on the U-shaped lock bridge.Existing plastics lock housing constitutes by upper shell and lower house, and the lower house bottom also is provided with through hole with the keyhole corresponding position, and key inserts keyhole from the through hole when unblanking.The deficiency that the padlock of existing shell with lock exists is: 1 padlock when using often falls to cause on the ground lock housing to break, and the rent junction of upper shell and lower house often; Though 2 plastics lock housings can prevent that the lock body external surface from getting rusty, but rainwater also can enter in the keyhole of lock body by the through hole of plastics lock housing bottom when being to use, perhaps in lock bridge enters the lock beam hole of lock body, permanent use back padlock inner body also can corrosion, damage, cause padlock malfunctioning.

Summary of the invention

Goal of the invention of the present utility model is to have overcome above-mentioned technological deficiency, and a kind of novel structure is provided, and the plastics lock housing is difficult for breaking, and rainwater can not enter lock body by the through hole of plastics lock housing bottom can be along the padlock in lock bridge enters the lock beam hole of lock body yet.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of padlock, comprise lock body, plastics lock housing and U-shaped lock bridge, the U-shaped lock bridge is contained on the lock body, keyhole is arranged on the lock body bottom, the plastics lock housing is wrapped on the lock body, and the plastics lock housing is made of upper shell and lower house, and the lower house bottom is provided with through hole with the keyhole corresponding position, the plastics lock housing is provided with the soft plastic bump protection ring, and the soft plastic bump protection ring is socketed in the junction of upper shell and lower house; The lower house bottom is provided with chute corresponding with lead to the hole site and that connect mutually, and slide block is set in the chute; Be enclosed with the U-shaped plastic sheath on the U-shaped lock bridge, be socketed with the hollow ring sealing ring on the U-shaped lock bridge between U-shaped plastic sheath free end and the lock body.

As preferably, the U-shaped lock bridge between described U-shaped plastic sheath free end and the lock body is provided with cannelure, and the hollow ring sealing ring is socketed on the cannelure, and sealing is better.

As preferably, described hollow ring sealing ring inner ring sidewall and lock bridge junction are provided with annular opening, and sealing is better.

As preferably, described slider bottom is provided with the shifting block that is connected as a single entity with it, and stretch out outside the through hole shifting block bottom, by the shifting block moving slider, uses convenient.

As preferably, described chute is on the bottom surface of lower house inboard, and slide block is between the bottom surface and lock body bottom surface of lower house inboard, and is simple in structure, convenient for production.

Adopt a kind of padlock of technique scheme, in the junction of upper shell and lower house the soft plastic bump protection ring is set, padlock falls on the ground can effectively prevent breaking of plastics lock housing by the damping of soft plastic bump protection ring; In the chute of lower house bottom slide block is installed, by opening or closure of the mobile realization through hole of slide block in chute, the situation sliding block that does not promptly insert key can prevent effectively that with the through hole closure rainwater from entering in the lock body from the through hole; Be enclosed with the U-shaped plastic sheath on the U-shaped lock bridge, can prevent that lock bridge from getting rusty, be socketed with the hollow ring sealing ring on the U-shaped lock bridge between U-shaped plastic sheath free end and the lock body, can prevent that rainwater is in lock bridge enters the lock beam hole of lock body.The advantage of this padlock is a novel structure, and is easy to use, not only can prevent that rainwater from entering lock body by the through hole of plastics lock housing bottom, and can prevent that rainwater is in lock bridge enters the lock beam hole of lock body.
