Description

Technical Field

[0001] This utility model relates to a novel handheld double-roller steel pipe painting tool, belonging to the technical field of paint application tools. Background Technology

[0002] With the popularization of the concept of green construction sites and the increasing standardization requirements in the industry, standardized steel pipe protection is widely used in engineering projects for edge protection, safety passages, and other temporary facilities. To meet the requirements of green construction sites and standardized construction, protective steel pipes transferred from old projects to new projects for continued use are often required to be refurbished and repainted with red and white paint. However, existing single-roller painting tools are only efficient in planar applications. When facing three-dimensional objects like steel pipes, a single roller often requires the operator to hold the roller firmly against the pipe, roll it back and forth, and constantly adjust the painting direction to ensure the entire pipe wall is painted. Such tools require the user to focus on keeping the brush close to the pipe and constantly adjust the direction of force and hand position to meet different painting requirements, resulting in low efficiency and wasting a significant amount of time and manpower. Utility Model Content

[0003] The purpose of this utility model is to provide a handheld double-roller steel pipe painting tool to improve the work efficiency when repainting steel pipes, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handheld double-roller steel pipe painting tool, comprising a grip, a connecting rod, and a roller brush, wherein the two ends of the connecting rod are respectively connected to the grip and the roller brush; the roller brush consists of at least two parallel rollers, the surface of which has brush bristles for painting; one end of the connecting rod is connected to the grip in a contracted and closed structure, and the other end of the connecting rod is rotatably connected to the end of the rollers via a shaft; the shaft of the connecting rod provides a relatively tightening pressure to the parallel rollers.

[0005] A further technical solution of this utility model is that, in the aforementioned handheld double-roller steel pipe painting tool, the parallel rollers have the same external dimensions to ensure synchronous painting during rolling, equal rolling distances on both sides, and similar amounts of paint on the brush bristles of the rollers, so as to achieve consistent painting effect.

[0006] The aforementioned handheld double-roller steel pipe painting tool has a grip that is either a short handle or a long handle extension rod, with different grips selected depending on the construction scenario.

[0007] The aforementioned handheld double-roller steel pipe painting tool has a connecting rod made of a tough metal material to ensure the clamping pressure of the two rollers. To facilitate the rollers from dipping in paint, the connecting rod has an L-shaped structure, so that the end of the roller not connected to the connecting rod can be immersed in the paint bucket.

[0008] Furthermore, in order to ensure that the paint can be quickly reset after the roller brushing is applied, the handheld double-roller steel pipe painting tool is equipped with a reset mechanism at the body of the connecting rod; the reset mechanism is a spring or elastic band.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application provides two working surfaces by employing two rollers working simultaneously, thus improving work efficiency. Simultaneously, this solution allows the user to apply force back and forth in one direction, driving the rollers to achieve the painting purpose, greatly improving work efficiency. Because the two rollers are constrained by the connecting rod in this solution, they provide an inward force when compressing the steel pipe; therefore, the user only needs to provide a pushing and pulling force to complete the painting of a section of the steel pipe's outer wall. Furthermore, this application's solution can not only be applied to painting steel pipes of different sizes, but also to thinner plates, concrete columns, etc., by adjusting the length of the connecting rod and the size of the rollers, thus meeting usage requirements and improving work efficiency. The structure of this application does not involve any motors or gear components; it relies solely on material deformation to meet usage requirements, without incurring additional manufacturing costs.

[0011] Figure 2 This is a structural schematic diagram from the second perspective of this embodiment. Detailed Implementation

[0012] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0013] This embodiment discloses a handheld double-roller steel pipe painting tool, such as... Figure 1-2As shown, it includes a grip 3, a connecting rod 2, and a roller brush 1. The grip 3 is a short-handled handle. The connecting rod 2 is made of a tough metal material and has an L-shaped structure. The two ends of the connecting rod 2 are connected to the grip 3 and the roller brush 1, respectively. The roller brush consists of two parallel rollers with the same external dimensions and brush bristles on their surface. One end of the connecting rod is connected to the grip with a tapered and closed structure, and the other end of the connecting rod is rotatably connected to the end of the rollers through a shaft. The rod body provides relatively tightening pressure to the parallel roller structure.

[0014] In this embodiment, the rollers and brush bristles are immersed in paint, allowing the brush bristles to be thoroughly soaked. Holding the handle, the center of the two rollers is aligned with the steel pipe to be coated, and the rollers are pushed so that the steel pipe passes between the two rollers and the brush bristles on the rollers roll evenly over the outer wall of the steel pipe. The handle is then tightened and pulled back. At this time, the pull-back angle can be slightly adjusted to pull back in a comfortable direction of force, so that the steel pipe passes through the two rollers again. This ensures that the coating can better cover the steel pipe wall that needs to be coated.

[0015] The embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. For those skilled in the art, after learning the contents of the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
