Description

Rolling brush

Technical Field

The utility model belongs to the technical field of building decoration instrument, concretely relates to paint balanced roller coating brush.

Background

The roller brush is composed of a handle and a roller, the roller is fixed on the handle through a mounting shaft, bristles are distributed on the outer surface of the roller, and the roller brush can be frequently used in the process of rolling and coating large-area paint in daily architectural decoration engineering. When the paint bucket is used, the roller is placed on a wall surface or a ceiling or the surface of an object by holding the handle to roll to realize painting after the outer surface of the roller fully absorbs paint when the roller is immersed into the paint bucket by holding the handle. This kind of traditional manual immersion fluid then carries out the roll-coating, need not take off the cylinder from scribbling the wall then place in the coating bucket dip in the coating in the use, then put again and carry out the roll-coating on the wall, constructor need constantly turn round or adjust the health angle, and intensity of labour is big, consumes time. In addition, the thickness of the paint dipped at different parts of the roller is different, so that the thickness of the paint which is smeared on the wall surface by using the outer surface of the roller at the back is not uniform enough. And the user can only roll and paint the wall surface within the limited height, and for the wall surface which is too much higher than the user, the height of the user per se needs to be improved by means of a ladder and the like.

Research and improvement are needed to solve the problems of the existing rolling brush.

Disclosure of Invention

The utility model aims at providing a roll and apply paint with a brush to the problem that traditional cylinder brush manual operation consumeed consuming time, reduce intensity of labour, paint more quick equilibrium.

In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: the utility model provides a rolling brush, includes rolling brush, handle, connecting axle and L type support frame, the rolling brush is installed on the connecting axle, L type support frame both ends are connected with connecting axle one end, handle one end respectively, still include feed pipe and drain board, the drain board internal surface touches with the rolling brush outer peripheral face mutually, the drain groove and the feed pipe intercommunication of drain board internal surface.

The mode of supplying liquid at the round brush surface is adopted, and when the round brush takes place to roll for the drain board, the coating in the drain groove is evenly coated on the surface, and the surface is the roller coating wall contact surface, therefore the coating distributes more evenly, utilizes the infusion of feed pipe to reduce manual operation's intensity, has reduced the process that need turn over to go to dip in the coating bucket and get the coating after the coating is scribbled on the round brush at every turn. Make a section of thick bamboo inside, outside all dip in full coating in the whole direct dip coating bucket of traditional cylinder, on the wall can't be paintd to inside coating, it is inconvenient also to wash causes the coating extravagant simultaneously, adopts the design that the drain board directly supplied liquid from the round brush outside, only coats full coating on the face is scribbled in the roll of round brush, is convenient for wash and has also saved the coating cost.

Furthermore, the liquid guide groove comprises a main flow channel and an auxiliary flow channel, wherein the main flow channel is arranged in the middle and at the periphery of the liquid guide plate and is communicated with the auxiliary flow channels extending towards two sides; the middle part of the main runner is communicated with the liquid supply pipe. The main runner is matched with the auxiliary runner, so that complete liquid supply is realized on the inner surface of the liquid guide plate, and the coating can be uniformly adhered to the rolling brush.

Furthermore, the width of the main flow channel is larger than that of the auxiliary flow channel; or the depth of the liquid guide groove gradually becomes shallow from the middle part to the periphery. The width and the degree of depth of sprue and vice runner are not uniform for coating flow transmission speed in earlier stage is accelerated, and later stage flow transmission face is wider.

Furthermore, the liquid guide plate has elasticity, and the cross section of the liquid guide plate is an elliptic arc; or the liquid guide plate is arranged below the side of the rolling brush. The liquid guide plate is made of elastic materials and designed to be an elliptical arc, so that the liquid guide plate can wrap the rolling brush, and the upper edge and the lower edge of the liquid guide plate have a certain limiting and pressing effect on the rolling brush. Because the user lifts the roller brush to carry out roller coating on the wall body when using, the liquid guide plate is arranged below the side of the roller brush, and the dripping can be effectively prevented.

Furthermore, the liquid guide groove is connected with the liquid supply pipe through a quick joint, so that the liquid guide groove is convenient to disassemble and assemble.

Furthermore, the handle is hollow, and the liquid supply pipe passes through the handle and is communicated with the liquid guide groove. The liquid supply pipe is arranged inside, so that adverse effects on the wall surface of a user caused by rolling and coating by the user due to exposed shaking are avoided.

Further, still include inside hollow telescopic link, round brush, telescopic link, handle connect gradually, the feed pipe passes in proper order handle, telescopic link. The utility model discloses a telescopic link structure makes the user can operate the wall of not too high, has avoided traditional roller coating to brush the handle short can only carry out the defect that the roller brush can't paint higher position at the wall of user's height certain limit.

Further, the paint spraying device also comprises a liquid storage bag used for storing paint, and the liquid storage bag is connected with the liquid supply pipe; an air pump and an exhaust valve which are inflated inwards are arranged on the liquid storage bag. The coating output that utilizes the air pump to supply liquid atmospheric pressure to the drain pipe is stable is also more balanced, can follow discharge valve and get rid of the gas in the stock solution bag after using.

Further, the liquid supply pipe is a hose. Is convenient to be arranged in the handle and the telescopic rod, and is also convenient to be stored and disassembled.

Furthermore, the lower end of the handle is provided with a flow regulating valve for regulating the flow of the feeding material.

Compared with the prior art, the utility model, beneficial effect is:

1. the roller coating can realize uniform liquid supply, is more balanced, and prevents the phenomena of liquid dropping and liquid leakage;

2. due to the design of the telescopic rod, a user can adapt to coating areas with different heights without additionally arranging other auxiliary tools such as ladders;

3. the pneumatic liquid storage bag is used as a liquid supply source, so that the continuity of paint conveying is ensured;

4. the rolling brush is easy to clean, the labor intensity of rolling coating is reduced, and the working efficiency and the rolling coating effect are improved.
