Description

Technical Field

[0001] This utility model relates to a construction tool, specifically a wall painting tool. Background Technology

[0002] In the field of interior decoration, wall painting is a crucial task, as its quality directly affects the final decoration effect and living experience. Traditional wall painting methods mainly rely on hand-held rollers, where workers dip the rollers into paint buckets to pick up paint paste before applying it to the wall. However, this method has many shortcomings.

[0003] First, traditional roller brushes can only pick up a limited amount of paint each time, forcing workers to frequently dip the brush into the paint bucket to re-grab paint. This not only increases the workload for workers but also severely impacts work efficiency. Furthermore, the frequent dipping and rolling motions can easily lead to uneven paint thickness at the joints, thus affecting the overall decorative effect of the wall.

[0004] Secondly, when using traditional roller brushes to pick up paint, excess paint often drips around the paint bucket or onto the wall, which not only wastes paint but also increases the difficulty of cleaning. Furthermore, the dripping paint can also stain the wall surface, further affecting the quality of the finish. Utility Model Content

[0005] The purpose of this invention is to provide a wall painting tool to solve the problems of low painting efficiency and poor painting quality of existing roller brushes.

[0006] This utility model is implemented as follows: a wall painting tool, the structure of which includes a brush rod, a connecting rod disposed on the brush rod, and a roller brush head disposed on the connecting rod;

[0007] The brush rod includes a slurry pushing rod, a slurry storage pipe sleeved on the slurry pushing rod, and a piston head disposed at the upper end of the slurry pushing rod;

[0008] The connecting rod includes a connecting pipe and a shaft tube connected to the connecting pipe. The shaft tube is used to cooperate with the roller brush head, and the connecting pipe is connected to the slurry storage pipe. A through hole for the paint to pass through is provided on the shaft tube.

[0009] Furthermore, the roller brush head includes an inner sleeve, a bristle layer disposed on the sleeve, and a bearing disposed on the sleeve.

[0010] Furthermore, an inlet pipe and an outlet pipe are provided at the upper end of the slurry storage pipe, and the connecting rod is connected to the outlet pipe.

[0011] Furthermore, a discharge check device is provided in the discharge pipe, and a feed check device is provided in the feed pipe.

[0012] Furthermore, check valves are provided on both the discharge pipe and the feed pipe.

[0013] Furthermore, the discharge anti-reverse device includes a discharge anti-reverse plate and a discharge limiting block. One end of the discharge anti-reverse plate is hinged to the inner wall of the discharge pipe, and the discharge limiting block is fixedly connected to the inner wall of the discharge pipe.

[0014] Furthermore, connectors are provided on both the discharge pipe and the feed pipe.

[0015] Furthermore, an anti-detachment handle is provided at the lower part of the slurry push rod, and an anti-detachment thread is provided on the anti-detachment handle.

[0016] This invention allows a sufficient amount of paint slurry to be drawn into the storage pipe in one go, significantly reducing the number of times the roller needs to be dipped in slurry, thus accelerating the construction progress. Because the storage pipe contains a large amount of paint, construction workers can continuously complete painting of large areas without frequently interrupting the work to dip the paint, saving time spent traveling between the paint bucket and the wall and improving overall construction efficiency.

[0017] This invention utilizes the propulsion action of a slurry pusher to continuously and evenly deliver paint to the roller brush head, ensuring a consistently sufficient amount of paint on the roller brush cylinder. This avoids the uneven thickness of wall paint caused by uneven paint application in traditional methods, thus improving the quality and effect of wall painting. The use of overflow holes on the roller brush head shaft for paint application reduces the problem of excess slurry dripping.

[0018] This invention utilizes through holes in the sleeve of the shaft tube and the roller brush head to allow the slurry to adhere evenly and in appropriate amounts to the roller brush head, reducing dripping and waste. This not only reduces the amount of paint used and saves on construction costs, but also simplifies subsequent cleaning.

[0019] This invention can be adapted to different types of roller brush heads, suitable for both short and long bristles, thus improving the applicability and flexibility of the tool and meeting different painting needs. Attached Figure Description

[0024] Example 1

[0025] like Figure 1 As shown, this utility model includes a brush rod 1, a connecting rod 2 attached to the brush rod 1, and a roller brush head 3 attached to the connecting rod 2. The brush rod 1 includes a lower slurry pusher rod 1-1, a slurry storage tube 1-2 sleeved on the slurry pusher rod 1-1, and a piston head 1-3 attached to the upper end of the slurry pusher rod 1-1. The piston head 1-3 is press-fitted with the inner wall of the slurry storage tube 1-2, and this tight fit ensures the stability and sealing of the coating in the container. The slurry storage tube 1-2 serves as a slurry storage tube for the coating. The piston head 1-3 is pushed or pulled by the slurry pusher rod 1-1 to move within the slurry storage tube 1-2, squeezing out or drawing the coating into the slurry storage tube 1-2. The slurry storage tube 1-2 is made of fiberglass, the slurry pusher rod 1-1 is made of stainless steel, and the piston head 1-3 is made of rubber.

[0026] The connecting rod 2 is a hollow tube to facilitate the delivery of paint from the storage tube 1-2 to the roller brush head 3. The connecting rod 2 includes a shaft tube 2-1 and a connecting tube 2-2. The shaft tube 2-1 mates with the roller brush head 3, and the connecting tube 2-2 connects the shaft tube 2-1 and the brush rod 1, allowing paint from the brush rod to be guided into the shaft tube 2-1. The roller brush head 3 is fitted onto the shaft tube 2-1, which has several through holes connecting the inside and outside of the shaft tube 2-1, allowing paint from the shaft tube 2-1 to flow out and into the roller brush head 3.

[0027] like Figure 2 As shown, the roller brush head 3 includes an inner sleeve (not shown), a bristle layer 3-1 fitted onto the sleeve, and two bearings 3-2 respectively installed at both ends of the sleeve. Several through holes are formed in the sleeve connecting the interior of the sleeve and the bristle layer 3-1. The sleeve is fitted onto the shaft tube 2-1. Paint enters the bristle layer 3-1 through the through holes in the sleeve, and the rotation of the roller brush head 3 applies the paint from the bristle layer 3-1 onto the wall. The type of roller brush head can be flexibly changed; it is suitable for both short and long bristles. This design allows the tool to adapt to different wall materials and painting needs, increasing its applicability and flexibility.

[0028] Two connecting pipes are provided at the upper end of the slurry storage pipe 1-2: one is the inlet pipe 1-5 for paint entry, and the other is the outlet pipe 1-4 for connection with the connecting rod 2. The outlet pipe 1-4 and the inlet pipe 1-5 are arranged in a Y-shape, and a connector 1-6 is installed on both the outlet pipe 1-4 and the inlet pipe 1-5. The connecting rod 2 is connected to the outlet pipe 1-4 through the connector 1-6. Specifically, the connecting pipe 2-2 of the connecting rod 2 is connected to the outlet pipe 1-4 through the connector 1-6. A sealing rubber gasket is provided in the connector 1-6 to ensure a firm seal at the connection. Before the paint is drawn out with the brush rod 1, a conduit is connected to the connector 1-6 of the inlet pipe 1-5, and the other end of the conduit is inserted into the paint container. By pulling down the slurry push rod 1-1, the paint is drawn into the slurry storage pipe 1-2.

[0029] A discharge check valve 4 is installed in the discharge pipe 1-4, and a feed check valve 5 is installed in the feed pipe 1-5. The discharge check valve 4 ensures that during paint extraction and application, paint can only flow from the storage pipe 1-2 to the connecting rod 2, preventing paint from flowing back from the connecting rod 2 to the storage pipe 1-2. The feed check valve 5 ensures that during paint extraction and application, paint can only enter the storage pipe 1-2 from the outside, preventing paint from flowing out from the feed pipe 1-5.

[0030] The discharge check device 4 includes a discharge check plate 4-1 and a discharge limiting block 4-2. One end of the discharge check plate 4-1 is hinged to the inner wall of the discharge pipe 1-4, and the discharge limiting block 4-2 is fixedly connected to the inner wall of the discharge pipe 1-4. The discharge limiting block 4-2 is arranged opposite to the hinged end of the discharge check plate 4-1, and the discharge limiting block 4-2 is located at the inner end of the discharge check plate 4-1.

[0031] The feed check device 5 includes a feed check plate 5-1 and a feed limiting block 5-2. One end of the feed check plate 5-1 is hinged to the inner wall of the feed pipe 1-5, and the feed limiting block 5-2 is fixedly connected to the inner wall of the feed pipe 1-5. The feed limiting block 5-2 is arranged opposite to the feed check plate 5-1, and the feed limiting block 5-2 is located at the outer end of the feed check plate 5-1.

[0032] An anti-detachment handle 6 is provided near the lower end of the slurry push rod 1-1. The anti-detachment handle 6 is provided with anti-detachment threads to ensure that the user can hold it firmly.

[0033] Example 2

[0034] like Figure 3 As shown, the structure of this embodiment is basically the same as that in Embodiment 1, except that the discharge check valve 4 installed in the discharge pipe 1-4 and the feed check valve 5 installed in the feed pipe 1-5 are both replaced by check valve 7. Check valve 7 is a valve that only allows fluid to flow in one direction. When the fluid attempts to flow in the opposite direction, the valve will automatically close, thereby preventing fluid backflow.
