Description

Rubber brush

Technical Field

The utility model belongs to the technical field of adhesive auxiliary tools, and relates to an adhesive brush.

Background

In the prior art, in order to ensure the connection stability between the pipe bodies, the pipe system connected by the socket joint mode generally smears an adhesive at the joint of the pipe bodies, so as to ensure the connection stability of the two pipe bodies which are connected by the socket joint mode and the tightness of the joint.

At present, the adhesive on the tube body is generally smeared by a rubber brush, for example, a brush with a bottle cap disclosed in China patent (issued publication number: CN 201525563U) comprises a tinplate bottle cap and a brush rod connected to the inner surface of the bottle cap, wherein a spherical brush head is fixed on the brush rod, and the spherical brush head is formed by binding a bundle of poly-acetate fiber by binding a bundle of wires.

In combination with the description of the reference document in paragraph 0022 and fig. 3, the brush head of the brush with the bottle cap is spherical, and is tightly tied at one end of the brush rod through the polyester fiber waist blocking, and the other end of the brush rod is welded and fixed with the middle part of the inner wall of the bottle cap through a spiral part formed by bending, and the brush with the bottle cap can be directly fixed on the glue bottle through the bottle cap after being used.

Although constructor can smear the adhesive through this take bottle lid brush to grafting department of body, but smear the in-process very easily and cause the adhesive on the body outer wall to smear unevenly, and then the seepage risk when causing follow-up pipe line system to use improves, and the brush-holder stud specifically is connected with the bottle lid through welded fastening's mode, the brush-holder stud can be continuous atress bending in the use, can appear very easily the rupture phenomenon after long-time continuous use, be used for the bottle of dress adhesive and bottle lid to be supporting the use in the real life, so both often sell together with the adhesive, in case the brush-holder stud appears the rupture, the user need communicate the bottle lid together to purchase and carry out the replacement installation, the practicality is relatively poor.

Disclosure of Invention

The utility model aims at solving the problems in the prior art, and provides a rubber brush, which aims at solving the technical problems that: and the adhesive smearing uniformity on the outer wall of the pipe body is improved while the practicability of the adhesive brush is ensured.

The aim of the utility model can be achieved by the following technical scheme: the utility model provides a glue brush, includes lid and brush-holder stud, its characterized in that has on the brush-holder stud one end lateral wall and is the column and have the brush head of hydroscopicity, the brush-holder stud other end with the lid can dismantle and be connected.

This glue brush specifically includes lid and brush-holder stud, through setting up the brush head that has hydroscopicity in the one end department of brush-holder stud, be the column through setting up the brush head, can carry out disposable rotatory brushing to the inner wall or the outer wall of pipe fitting, it is more even to guarantee to scribble the brush area wider, it is faster to scribble the brush speed, and can dismantle the connection on the other end and the lid of brush-holder stud, from this, make brush-holder stud and lid can be dismantled and replaced when keeping being connected stably relatively, and this glue brush can be connected through the lid with the bottle that holds the adhesive when accomodating, thereby realize gluing the brush and accomodate on the bottle, after last using this glue brush, if the brush-holder stud takes place the fracture time, the user can be with the brush-holder stud with the socket connection together again in the mode of pegging graft after tearing off from the lid, and the manufacturer also can make the lid and have the brush-holder stud separately and sell, the user can purchase and assemble the replacement according to own demand, from this practicality of guaranteeing glue brush is higher.

In the rubber brush, a socket is formed in the inner wall of the cover body, and one end, detachably connected with the cover body, of the brush rod is inserted into the socket.

The brush-holder stud is specifically connected with the cover body in an inserting manner through being matched with the inserting opening, so that the brush-holder stud and the cover body are detachably connected, and as an alternative scheme, an internal thread can be arranged on the inside of the inserting opening, an external thread is arranged on the outer wall of the brush-holder stud, and the brush-holder stud and the cover body are connected in a threaded manner.

In the rubber brush, the brush head is cylindrical and made of fiber cotton material, the length of the brush head is more than or equal to 4cm, and the diameter of the brush head is more than or equal to 2.5 cm.

The brush head is made of fiber cotton materials specifically so as to ensure that the brush head has the advantage of high water absorbability, ensure that the brush head can absorb enough adhesive when being used for gluing, ensure that the diameter of the brush head is more than or equal to 2.5 cm and the length of the brush head is more than or equal to 4 cm, and further ensure that the pipe fitting can be rotationally coated in place at one time when being used for gluing, and the brush is not required to be repeatedly coated, so that the brush is ensured to be coated uniformly and simultaneously more convenient.

In the rubber brush, the brush rod is formed by winding a plurality of steel wires, and the diameter of the brush rod is more than or equal to 0.2 cm.

The brush rod is formed by winding steel wires, and the diameter of the brush rod is more than or equal to 0.2 cm, so that the brush rod is ensured to maintain higher structural strength.

In the rubber brush, a connecting column protruding towards the direction of the cover opening is arranged at the center of the inner wall of the cover body, and the socket is arranged on the connecting column.

The inner wall center department of lid is provided with the spliced pole, and the socket is seted up on the spliced pole to ensure that the socket has certain degree of depth, insert the back at brush-holder stud one end, guarantee that the lid can be through the socket to effectively fix the brush-holder stud.

In the above-mentioned glue brush, the cover body inner wall is further provided with a ring-shaped protection edge, and the protection edge is arranged around the connecting column.

Through the setting of protection edge for the spliced pole can obtain effective protection, prevents to a certain extent that the spliced pole from receiving the foreign object collision to take place to fracture, improves the life of lid from this.

Compared with the prior art, the rubber brush has the following advantages:

Through setting up the brush head and being columnar and be fixed in brush-holder stud one end to peg graft fixedly brush-holder stud one end and the socket on the lid, in order to ensure that the brush-holder stud can carry out disposable rotatory brushing to the inner wall or the outer wall of pipe fitting in place, guarantee the rubber coating homogeneity, can take out the fracture part from the socket after again pegging graft both fixedly when the brush-holder stud breaks, perhaps correspond to change the lid or have the brush-holder stud structure of brush head, the practicality is higher.
