Abstract

The utility model relates to a spray gun for maintaining cylinder lock, which is composed of a plastic gun tube and a gun body. The small head end of the gun tube is inserted into the inner hole of the gun body, and the gun handle of the gun body has good elasticity. An inner structure is a hollow cavity, and the hollow cavity is provided with solid lubricant (such as graphite powder or lead powder). The gun bore is communicated with the inner hollow cavity of the gun body. During use, the projecting thin isosceles triangle of the gun opening aims at a key hole. The gun handle of the gun body is pressed, and the solid lubricant entering the gun bore is sprayed into the inside of the key hole. The utility model has the advantages of convenient fabrication, convenient operation, small size, and low cost.

Description

Spray gun for maintaining cylinder lock

The utility model relates to a kind of spray gun that maintains used for spring lock.

The way of existing maintenance cylinder lock is that the pencil-lead powder is poured in the keyhole, inserts the movable core of key, and movable parts such as core and pellet shot from a slingshot are lubricated.This way is very convenient for the padlock maintenance, but is not easy very much the pencil-lead powder is poured in the keyhole for the cylinder lock that is fixedly mounted on the door.

The purpose of this utility model is to design a kind of above-mentioned deficiency that overcomes, and sliding agent is sprayed into the spray gun in the keyhole easily.

The purpose of this utility model is achieved in that its structure is the plastics pocket pistol, form by gun barrel and body of a gun two parts, one end of gun barrel inserts in the body of a gun endoporus and can rotate mutually, the small of the stock of the body of a gun is a hollow-core construction, flexible, sliding agent (as powdered graphite or pencil-lead powder) is housed in the cavity of the small of the stock, when extruder firmly the time, the sliding agent in the cavity can be sprayed in the keyhole.

The utlity model has simple for productionly, easy to use, volume is little, the advantage that cost is low.

Describe the utility model feature in detail below in conjunction with accompanying drawing:

Fig. 1 is the constructed profile of the utility model design.

Fig. 2 is the left view of the utility model muzzle.

By shown in Figure 1, the spray gun of maintenance used for spring lock is made of the plastics gun barrel 1 and the body of a gun 2, and gun barrel 1 has diameter bigger major part 4 and the less microcephaly 3 of diameter.Gun barrel microcephaly 3 diameter is identical with the diameter of bore of the body of a gun 2, when gun barrel microcephaly 3 inserts the endoporus of the body of a guies 2, can rotate mutually, and be in contact with one another the position must not the gap.The small of the stock of the body of a gun 2 is inner to be cavity structure, flexible.The bore 5 of gun barrel 2 is connected with the cavity 8 of the body of a gun 2.About 30mm～the 40mm of the body of a gun 1 length, the about 1.5～2mm of bore 5 diameters.As illustrated in fig. 1 and 2, the feature of muzzle is a tall and thin isosceles triangle 6 that protrudes forward, isosceles triangle 6 bottom side lengths 2～2.5mm, and high about 7mm, the muzzle of bore 5 is positioned at second position of isosceles triangle 6.Gun barrel 1 microcephaly's tail end structure is a flared structure 7.

Before the work, extract gun barrel 1 earlier, solid lubricant (as powdered graphite or pencil-lead powder) is packed in the cavity 8 of the small of the stock by the endoporus of the body of a gun, the dosage of packing into accounts for cavity 8 volumes 1/4～1/3 of the body of a gun 2.Can use in the endoporus with the gun barrel microcephaly 3 insertion body of a guies 2 again.During work, twist gun barrel earlier, the small of the stock that makes the body of a gun 2 is down the time, and the direction of the tall and thin isosceles triangle 6 of muzzle is consistent with the direction of keyhole.Then, temporarily block muzzle, make muzzle down, reduce the gun barrel position, solid lubricant is poured in the bore 5 with finger.Then, the gun barrel 1 that maintains an equal level is aimed at keyholes with the isosceles triangle 6 that muzzle protrudes forward, and is pushed the small of the stock of the body of a gun 2, and the air pressure that makes cavity 8 sprays into the solid lubricant of bore 5 in the keyhole, inserts the movable core of key at last and gets final product.

Claims

1, the spray gun of maintenance used for spring lock is made of the gun barrel and the body of a gun of plastics, it is characterized in that microcephaly's one end of gun barrel is inserted in the body of a gun endoporus, can rotate mutually, and the contact site must not be gapped, and the small of the stock of the body of a gun is cavity structure, and is flexible; The bore of gun barrel is connected with the cavity of the body of a gun; Solid lubricant (as powdered graphite or pencil-lead powder) is housed in the cavity.

2, the spray gun of maintenance used for spring lock according to claim 1 is characterized in that the about 30～40mm of barrel length, the about 1.5～2mm of the bore diameter of gun barrel.

3, the spray gun of maintenance used for spring lock according to claim 1, the muzzle end that it is characterized in that gun barrel are a tall and thin isosceles triangle that protrudes forward, and its base is about 2～2.5mm, high about 7mm; The another port of gun barrel is a flared structure.
