Description

Technical Field

[0001] This utility model relates to the field of steel pipe painting tools, specifically a steel pipe painting tool. Background Technology

[0002] In the construction process, steel pipes are a common building material and are widely used in various stages such as scaffolding erection and edge protection. However, painting is an essential task in the use and maintenance of steel pipes. It can not only protect steel pipes from environmental corrosion and extend their service life, but also improve the safety and overall aesthetics of the construction site.

[0003] However, painting steel pipes mainly relies on manual brushes. This method results in low painting efficiency because the contact area between the brush and the steel pipe is relatively small due to the line contact. Multiple brushing operations on multiple surfaces are required to achieve the desired coverage. This not only increases the labor intensity of construction workers but also prolongs the construction period and affects the project progress. Furthermore, during the painting process, the friction and pressure between the brush bristles and the surface of the steel pipe can easily cause paint to splatter and drip, leading to paint waste and pollution of the construction site environment. This not only increases construction costs but may also have adverse effects on the surrounding environment. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a steel pipe painting tool to solve the technical problems of traditional manual brush painting methods, such as small contact area, low painting efficiency, high labor intensity, long construction period, paint waste and serious environmental pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe painting tool, comprising a painting tool, the painting tool including a main brush cylinder, a movable brush cylinder mounted on the back of the main brush cylinder via a rotating shaft, both the main brush cylinder and the movable brush cylinder being provided with bristles, the main brush cylinder and the movable brush cylinder being arranged in a ring structure, and the main brush cylinder and the movable brush cylinder being closed to encircle the steel pipe, the back of the movable brush cylinder being provided with a groove, and a locking hole being provided in the groove;

[0006] A handle is provided above the outer surface of the main brush cylinder, and a movable groove is provided inside the main brush cylinder, with a locking mechanism provided in the movable groove.

[0007] By adopting the above technical solution, the main brush cylinder and the movable brush cylinder form an openable and closable ring structure through the rotating shaft, which can completely wrap the surface of the steel pipe, significantly increase the paint contact area, make the paint evenly cover the surface and reduce the number of brushings, effectively improve the painting efficiency, reduce labor intensity and shorten the construction cycle.

[0008] Furthermore, the locking mechanism includes a movable rod that engages and slides with a movable slot.

[0009] By adopting the above technical solution, the movable rod achieves stable displacement through the snap-fit ​​sliding design, providing precise guidance for the extension and retraction of the locking pin, ensuring precise matching between the locking mechanism and the locking hole of the movable brush tube, and avoiding uneven paint film caused by brush tube displacement during the painting process.

[0010] Furthermore, one end of the movable rod passes through the handle and is provided with a locking pin, while the other end of the movable rod abuts against a spring, and the spring is used to cause the movable rod to return to its original position.

[0011] By adopting the above technical solution, the spring and the locking pin form a self-locking structure. When the locking pin is aligned with the lock hole, the spring automatically pushes the movable rod to reset, so that the locking pin is embedded in the lock hole to achieve quick locking. The operation can be completed with one hand, which significantly improves the convenience and safety of tool use.

[0012] Furthermore, a push block groove is provided at the top of the handle, and a push block is provided at the top of the movable rod, wherein the push block engages and slides with the push block groove.

[0013] By adopting the above technical solution, the locking and sliding design of the push block and the push block slot is ergonomic. Operators can push the push block to unlock it with their thumb without the need for additional tools. It can still maintain efficient operation in confined spaces or high-altitude operation scenarios, while avoiding the risk of accidental contact.

[0014] Furthermore, a mounting surface is provided on the lower outer surface of the main brush cylinder, and a leak-receiving mechanism is detachably connected to the mounting surface.

[0015] By adopting the above technical solution, the mounting surface provides a standardized connection interface for the leak-connecting mechanism, which facilitates quick disassembly and maintenance, while ensuring the sealing between the leak-connecting mechanism and the main brush cylinder to prevent paint from leaking to the outside of the tool.

[0016] Furthermore, the leak-catching mechanism includes a leak-catching seat, which is fixedly connected to the mounting surface by mounting bolts. The leak-catching seat has a hollow groove inside and is arranged in a "V" shape. The leak-catching seat is used to catch dripping paint.

[0017] By adopting the above technical solution, the "V"-shaped drain seat utilizes gravity guidance to allow dripping paint to quickly converge into the empty groove along the slope, reducing paint residue. Combined with the detachable design, it facilitates centralized cleaning, reduces paint waste and pollution at the construction site, and meets green construction standards.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model includes a painting tool, a main brush cylinder, a rotating shaft, a movable brush cylinder, brush bristles, a groove, a locking hole, a handle, a movable groove, a mounting surface, a locking mechanism, a movable rod, a locking pin, a push block, and a spring. The main brush cylinder and the movable brush cylinder are arranged in a ring structure and connected by the rotating shaft, which can close and hug the steel pipe. Compared with the traditional manual brush painting method, this ring-shaped painting method significantly increases the paint contact area, thereby improving painting efficiency and reducing the need for multiple painting operations on multiple surfaces to achieve the ideal coverage effect. Moreover, the design of the locking mechanism can fix the position of the movable brush cylinder, ensuring the stability of the tool during the painting process, further improving the painting quality and efficiency. The ingenious combination of the push block and the spring allows the operator to easily and quickly operate the locking mechanism to achieve rapid opening and closing of the brush head, reducing the labor intensity of the construction workers.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1:

[0028] A steel pipe painting tool, such as Figure 1-4 As shown, the painting tool 1 includes a main brush cylinder 101. A movable brush cylinder 103 is mounted on the back of the main brush cylinder 101 via a pivot 102. Both the main brush cylinder 101 and the movable brush cylinder 103 are provided with brush bristles 104. The main brush cylinder 101 and the movable brush cylinder 103 are arranged in a ring structure. When the main brush cylinder 101 and the movable brush cylinder 103 are closed, they encircle the steel pipe. A groove 105 is provided on the back of the movable brush cylinder 103, and a locking hole 106 is provided in the groove 105.

[0029] A handle 107 is provided above the outer surface of the main brush cylinder 101. An active groove 108 is provided inside the main brush cylinder 101, and a locking mechanism 2 is installed within the active groove 108. This design, through the hinged connection between the main brush cylinder 101 and the active brush cylinder 103, encircles the steel pipe for painting, improving painting efficiency and uniformity. Simultaneously, the cooperation between the active groove 108 and the locking mechanism 2 enables quick locking and unlocking of the brush cylinder, enhancing operational convenience and safety. The ring-shaped structure design allows the painting tool to better conform to the surface of the steel pipe, reducing blind spots and improving painting quality.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The locking mechanism 2 includes a movable rod 201, which engages and slides with the movable groove 108. The engaging and sliding design of the movable rod 201 and the movable groove 108 enables the locking mechanism 2 to move flexibly, making it easy to quickly lock or unlock the movable brush tube 103 as needed during the painting process, thus improving the flexibility and practicality of the painting tool.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 One end of the movable rod 201 passes through the handle 107 and is equipped with a locking pin 202. The other end of the movable rod 201 abuts against a spring 204, which is used to cause the movable rod 201 to return to its original position. Through the cooperation of the locking pin 202 and the lock hole 106, the movable brush cylinder 103 is securely locked. The design of the spring 204 allows the movable rod 201 to automatically return to its original position after unlocking, improving the automation level and ease of operation of the painting tool. This design not only ensures the stability of the painting process but also simplifies the operation process and improves work efficiency.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4The top of the handle 107 has a push block groove, and the top of the movable rod 201 has a push block 203. The push block 203 engages and slides with the push block groove. This engaging and sliding design allows the operator to control the movement of the movable rod 201 by pushing the push block 203, thereby locking and unlocking the brush tube. This design not only facilitates the operator's operation but also improves the ease of use and comfort of the painting tool.

[0033] Example 2:

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A mounting surface 109 is provided on the lower outer surface of the main brush cylinder 101. A drip collection mechanism 3 is detachably connected to the mounting surface 109. By providing a detachable drip collection mechanism 3 on the main brush cylinder 101, the paint dripping during the painting process can be effectively collected, preventing paint from polluting the working environment or causing waste. This design improves the environmental friendliness of the painting tool and reduces the cost of use.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The leak-catching mechanism 3 includes a leak-catching seat 301, which is fixedly connected to the mounting surface 109 by mounting bolts 303. The leak-catching seat 301 has a hollow groove 302 and is arranged in a "V" shape to catch dripping paint. The "V" shape design allows the paint to flow along the inclined surface of the leak-catching seat 301 into the hollow groove 302, preventing paint accumulation and overflow on the leak-catching seat 301. The fixing method of the mounting bolts 303 ensures the stable installation of the leak-catching seat 301, improving the overall stability and reliability of the painting tool. This design not only improves the leak-catching effect but also facilitates the cleaning and maintenance of the leak-catching mechanism.

[0036] The implementation principle of this embodiment is as follows: First, the operator takes out the painting tool 1. At this time, the main brush tube 101 and the movable brush tube 103 are in a rotating state and can be opened and closed relative to each other. When adding paint, the operator needs to open the movable brush tube 103 relative to the main brush tube 101 so that the brush bristles 104 can be fully immersed in the paint.

[0037] When adding paint, the operator immerses the entire open painting tool into the paint bucket to ensure that the brush bristles 104 can be evenly and fully dipped in paint. After the brush is dipped in paint, the operator removes the painting tool from the paint bucket and adjusts it to a suitable angle for operation.

[0038] Subsequently, the operator places the main brush cylinder 101 under the steel pipe and flips the movable brush cylinder 103 over from above so that it closes relative to the main brush cylinder 101, thereby encircling the steel pipe. During this process, the bristles 104 inside the main brush cylinder 101 and the movable brush cylinder 103 are in close contact with the surface of the steel pipe, forming a ring-shaped painting surface.

[0039] To ensure that the movable brush cylinder 103 does not move arbitrarily during the painting process, the operator needs to fix it by using the locking mechanism 2. Specifically, the operator operates the push block 203 through the push block groove at the top of the handle 107, which drives the movable rod 201 to slide in the movable groove 108, thereby controlling the extension and retraction of the locking pin 202. When the movable brush cylinder 103 flips over and closes with the main brush cylinder 101 to hug the steel pipe, the operator pushes the push block 203 to make the locking pin 202 extend and insert into the locking hole 106 on the back of the movable brush cylinder 103, thereby locking the movable brush cylinder 103 in a fixed position.

[0040] Once locked, the operator can begin painting the steel pipe. Because the bristles 104 are in close contact with the surface of the steel pipe and form a ring-shaped painting surface, a large area of ​​painting can be completed in one go, greatly improving painting efficiency.

[0041] In addition, in order to catch dripping paint and reduce paint waste and environmental pollution, this utility model is also equipped with a drip collection mechanism 3. During the painting process, if paint drips, it will be caught by the drip collection seat 301 and flow into the empty groove 302 inside it. The "V" shaped structure design of the drip collection seat 301 helps to collect dripping paint more effectively. When the paint in the drip collection seat 301 accumulates to a certain extent, the operator can easily disassemble it for cleaning.
