Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and specifically relates to a device for improving the painting speed of fire-fighting pipes. Background Technology
[0002] In the construction industry, pipes are painted from multiple perspectives, including corrosion protection, oxidation resistance, friction reduction, visibility of markings, temperature control, aesthetics, and quality. In actual construction, most painting is done on-site rather than by the manufacturer directly spraying paint onto the pipes. In practice, fire-fighting pipes are placed in open areas and their surfaces are painted to maintain pipe performance, extend lifespan, improve safety, and enhance appearance.
[0003] Existing technologies mainly use straight rollers for painting, which is slow for painting curved surfaces, thus reducing the painting process. This phenomenon has become a problem that urgently needs to be solved by those skilled in the art. Therefore, there is an urgent need for a device to improve the painting speed of fire pipes to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a device for improving the painting speed of fire pipes, in order to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for improving the painting speed of fire-fighting pipes, including a pin shaft, two handles on the outer wall of the pin shaft, a support rod crosswise at one end of the two handles, and a roller on the outer wall of the support rod. By providing the pin shaft, handles, support rod, and roller, it is convenient to adjust according to the size of the pipe, thereby improving the applicability range. Moreover, the painting range is larger than that of a straight roller, thereby improving the efficiency of pipe painting and meeting people's work needs.
[0006] Furthermore, the support rods are distributed in an arc shape, and the support rods are rotatably connected to the handle and the pin, which facilitates adjustment after unfolding or folding.
[0007] Furthermore, several rollers are distributed on the outer wall of the support rod, and the rollers are arranged in an arc shape, which facilitates the effective coating work of the rollers.
[0008] Furthermore, the roller and the support rod are rotatably connected, which facilitates the rotation of the roller.
[0009] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,
[0010] (1) By setting pins, handles, support rods and rollers, it is easy to adjust according to the size of the pipe, thereby improving the applicability. Moreover, the brushing range is larger than that of straight rollers, thereby improving the efficiency of pipe painting and meeting people's work needs. Attached Figure Description
[0011] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:

[0015] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0016] Please see Figure 1-2 This utility model provides a technical solution: a device for improving the painting speed of fire pipes, including a pin 1, two handles 2 on the outer wall of the pin 1, a support rod 3 crosswise at one end of the two handles 2, and a roller 4 on the outer wall of the support rod 3. By setting the pin 1, handles 2, support rod 3 and roller 4, it is convenient to adjust according to the size of the pipe, thereby improving the applicability range. Moreover, the painting range is larger than that of a straight roller, thereby improving the efficiency of pipe painting and meeting people's work needs.
[0017] Furthermore, the support rods 3 are distributed in an arc shape, and the support rods 3 are rotatably connected to the pin 1 via the handle 2, which facilitates adjustment after unfolding or merging.
[0018] Furthermore, there are several rollers 4 distributed on the outer wall of the support rod 3, and the rollers 4 are distributed in an arc shape, which facilitates the effective painting work of the rollers 4.
[0019] Furthermore, the roller 4 and the support rod 3 are rotatably connected, which facilitates the rotation of the roller 4.
[0020] In use, first turn handle 2, causing it to rotate support rod 3 in a scissor-like motion on the outer wall of pin 1, thereby adjusting the paint size. This is beneficial for painting pipes of different sizes. After adjustment, slide support rod 3 by turning handle 2, causing support rod 3 to slide and rotate roller 4, which then paints the outer wall of the pipe. The arc shape of roller 4 greatly increases the contact area compared to a straight roller, thus effectively improving painting efficiency and solving the problem of slow painting speed.
