Description

Technical Field

[0001] This utility model relates to the technical field of handheld painting devices, specifically to a painting device. Background Technology

[0002] Deep foundation pit cushion layer is a structural layer placed below the base layer to improve the working conditions of the soil foundation. In construction projects, the deep foundation pit cushion layer is in direct contact with the soil and is easily eroded by groundwater, chemicals, etc. Applying anti-corrosion coating can effectively isolate these harmful substances, protect the cushion layer material from corrosion, and thus extend the service life of the cushion layer.

[0003] Currently, the painting of deep foundation pit bedding layers is still in the stage of manual painting. That is, after the anti-corrosion coating is evenly applied to the roller brush, the person holds the handle of the roller brush and moves it back and forth. By continuously brushing the roller brush on the deep foundation pit bedding layer, the painting work is completed.

[0004] However, since the paint is poured directly onto the roller brush, controlling the coating thickness becomes very difficult, often resulting in uneven coating, affecting aesthetics and anti-corrosion performance; moreover, the lack of a paint flow rate control mechanism means that the flow rate and velocity of the paint cannot be precisely controlled during the coating process, leading to low coating efficiency and unsatisfactory coating results.

[0005] Therefore, existing technologies need further development. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a coating device to solve the technical problem that roller brushes are difficult to control the flow rate and coating thickness of paint.

[0007] To achieve the above technical objectives, the present invention adopts the following technical solution: A coating device is provided, comprising: a storage tank with a discharge port; a coating assembly including a support rod and a roller, one end of the support rod being connected to the storage tank and the other end of the support rod being connected to the roller, the roller being rotatably disposed below the discharge port; and a material control assembly including a first gripping rod and a moving component, the moving component being movably connected to the support rod. By manipulating the first gripping rod, the moving component pushes the support rod to move, thereby causing the roller to move relative to the discharge port, thus adjusting the distance between the roller and the discharge port to control the flow rate of the coating.

[0008] Furthermore, the material control assembly also includes two fixing rings, which are respectively set on both sides of the storage box. The support rods on both sides of the roller are respectively sleeved on each fixing ring, so that the support rods can move telescopically relative to the storage box, thereby adjusting the distance between the roller and the discharge port.

[0009] Furthermore, the material control assembly also includes two return springs. The support rod is sleeved on the return springs, one end of the return spring is connected to the fixed ring, and the other end of the return spring is connected to the end of the support rod. When the roller moves away from the discharge port, the return spring is compressed. After the first grip is released, the return spring returns to its original position, driving the roller to move closer to the discharge port, thereby blocking the discharge port.

[0010] Furthermore, an anti-detachment block is provided at the end of the support rod, and a return spring is sleeved on the support rod between the anti-detachment block and the fixing ring. The diameter of the anti-detachment block is larger than the diameter of the support rod to provide support and limit the support rod and prevent the support rod from falling off.

[0011] Furthermore, the moving component is a gear, and a rack that meshes with the gear is provided on the support rod. Pulling the first grip rod drives the gear to rotate, causing the material control component to move along the rack, thereby driving the support rod to extend and retract relative to the storage box.

[0012] Furthermore, there are two gears and two racks, with each rack mounted on its own support rod; the first grip rod is connected to the two gears via a bracket, with the two gears mounted at both ends of the bracket, and the first grip rod positioned at the center of the bracket, on the side of the bracket furthest from the two gears.

[0013] Furthermore, the first grip bar includes a first sleeve bar and a first telescopic bar. The first sleeve bar is fixed on the bracket, and the first telescopic bar is telescopically disposed within the first sleeve bar to adjust the length of the first grip bar. A first bolt is provided on the first sleeve bar, and the length of the first telescopic bar is adjusted by rotating the first bolt to release or fix the first telescopic bar.

[0014] Furthermore, a second gripping rod is also provided on the storage box. The second gripping rod includes a second sleeve rod and a second telescopic rod. The second sleeve rod is fixed to the box wall of the storage box, and the second telescopic rod is telescopically installed inside the second sleeve rod to adjust the length of the second gripping rod. A second bolt is provided on the second sleeve rod. The length of the second telescopic rod is adjusted by rotating the second bolt to release or fix the second telescopic rod.

[0015] Furthermore, the bottom of the second telescopic rod is provided with multiple anti-slip grooves at intervals along its length. The anti-slip grooves are used to prevent the hand from slipping when gripping the second handle during operation.

[0016] Furthermore, the storage bin is also equipped with a feed inlet, which is positioned opposite to the discharge outlet. The feed inlet is covered with a sealing cover, which is detachably installed and used to seal the feed inlet.

[0017] Beneficial effects:

[0018] 1. This utility model achieves adjustment of the distance between the roller and the discharge port through a material control component, enabling users to precisely control the flow rate of the paint. This flow rate control mechanism avoids the phenomenon of too much or too little paint, solves the problem of difficulty in controlling the paint flow rate and coating thickness in traditional painting devices, and improves the uniformity of the coating effect.

[0019] 2. This utility model uses a reset spring design in the material control component to enable the roller to automatically return to a position close to the discharge port after the operation stops, preventing paint from flowing out, thereby ensuring the cleanliness of the painting device and the convenience of operation.

[0020] 3. The grip of this coating device features an anti-slip groove design, effectively preventing hand slippage and enhancing stability, making operation more comfortable and safer. Furthermore, the adjustable grip length adapts to different scenarios, further improving the device's flexibility. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] According to an embodiment of this utility model, a coating device is provided. Please refer to [link / reference]. Figures 1 to 3 The system includes: a storage tank 1 with a discharge port 11; a coating assembly 2, comprising a support rod 21 and a roller 22, one end of the support rod 21 being connected to the storage tank 1 and the other end being connected to the roller 22, the roller 22 being rotatably positioned below the discharge port 11; and a material control assembly 3, comprising a first gripping rod 31 and a moving component 32, the moving component 32 being movably connected to the support rod 21. By manipulating the first gripping rod 31, the moving component 32 pushes the support rod 21 to move, thereby moving the roller 22 relative to the discharge port 11, thus adjusting the distance between the roller 22 and the discharge port 11 to control the flow rate of the coating. When the storage tank 1 is filled with coating and not in use, the roller 22 is positioned below the discharge port 11 and blocks the discharge port 11 to prevent coating from flowing out. The roller 22 is connected to the support rod 21 via an adjusting shaft 211, and the roller 22 rotates on the adjusting shaft 211. When starting to apply the paint, lift the painting device. At this time, the roller 22 moves downwards under gravity. Pull up the first grip 31, and the moving component 32 pulls the roller 22. Adjust the distance between the roller 22 and the outlet 11 by raising the first grip 31 according to the required paint thickness. This causes the moving component 32 to move the support rod 21, which in turn moves the roller 22, thus adjusting the distance between the roller 22 and the outlet 11. To increase the paint flow rate, extend the first grip 31 further away from the outlet 11; to decrease the paint flow rate, pull back the first grip 31, bringing the roller 22 closer to the outlet 11. After adjusting the distance between the roller 22 and the outlet 11, the painting operation can begin. During the painting process, the distance between the roller 22 and the outlet 11 should be adjusted as needed. Through the design of the material control component 3, the distance between the roller 22 and the outlet 11 can be flexibly adjusted, effectively controlling the paint flow rate. This control method avoids the problem of difficult paint flow control in traditional painting methods. The distance between the roller 22 and the discharge port 11 is adjustable, allowing users to adjust the paint thickness according to actual needs. This avoids the uneven coating thickness caused by traditional direct pouring of paint, ensuring a uniform coating thickness. The coating device of this embodiment solves the technical problem in related technologies where roller brushes are difficult to control the paint flow rate and coating thickness.

[0028] See Figure 1 and Figure 2In this embodiment, the coating device, the material control assembly 3 further includes two fixing rings 33, which are respectively disposed on both sides of the material storage tank 1. Support rods 21 on both sides of the roller 22 are respectively sleeved on each fixing ring 33, allowing the support rods 21 to extend and retract relative to the material storage tank 1, thereby adjusting the distance between the roller 22 and the discharge port 11. Through the guiding action of the fixing rings 33, the support rods 21 can move smoothly and steadily, avoiding uneven coating caused by shaking or displacement. With the support of the fixing rings 33, when adjusting the distance between the roller 22 and the discharge port 11, the user only needs to pull the first grip 31 and push the support rods 21 through the moving component 32, without worrying about the support rods 21 falling off or deviating from their position.

[0029] See Figure 2 In this embodiment of the coating device, the material control assembly 3 further includes two return springs 34. A support rod 21 is sleeved on the return springs 34. One end of each return spring 34 is connected to a fixing ring 33, and the other end is connected to the end of the support rod 21. When the roller 22 moves away from the discharge port 11, the return spring 34 is compressed. After the first grip 31 is released, the return spring 34 returns to its original position, causing the roller 22 to move closer to the discharge port 11, thereby blocking the discharge port 11. When the roller 22 is operated to move away from the discharge port 11, the return spring 34 is compressed and stores energy. Once the first grip 31 is released, the return spring 34 releases its stored energy, pushing the support rod 21 and the roller 22 to automatically move closer to the discharge port 11 until the roller 22 blocks the discharge port 11 again. This function greatly simplifies the operation process and improves work efficiency.

[0030] See Figure 2 In this embodiment of the coating device, an anti-detachment block 23 is provided at the end of the support rod 21. A return spring 34 is sleeved on the support rod 21 between the anti-detachment block 23 and the fixing ring 33. The diameter of the anti-detachment block 23 is larger than the diameter of the support rod 21 to provide support and limit the support rod 21 and prevent the support rod 21 from falling off. The anti-detachment block 23 prevents the support rod 21 from falling off the fixing ring 33 during telescopic movement.

[0031] See Figure 2In this embodiment of the coating device, the moving component 32 is a gear 321, and a rack 24 meshing with the gear 321 is provided on the support rod 21. Pulling the first grip 31 drives the gear 321 to rotate, causing the material control component 3 to move along the rack 24, thereby causing the support rod 21 to extend and retract relative to the storage box 1. The cooperation between the gear 321 and the rack 24 enables precise movement control. Since the number of teeth on the gear 321 and the tooth pitch on the rack 24 are fixed, each time the first grip 31 is pulled, the rotation of the gear 321 will cause the support rod 21 to extend and retract a certain distance. This precise control capability allows the user to accurately adjust the distance between the roller 22 and the discharge port 11 as needed, thereby obtaining a uniform coating effect.

[0032] See Figure 2 In this embodiment of the coating device, there are two gears 321 and two racks 24, each rack 24 is respectively mounted on its own support rod 21; the first grip rod 31 is connected to the two gears 321 through the bracket 35, the two gears 321 are respectively mounted at both ends of the bracket 35, and the first grip rod 31 is located at the center of the bracket 35, on the side of the bracket 35 away from the two gears 321. This arrangement makes the operation more comfortable and convenient for the user, and the force on both sides of the gears 321 is balanced. Adjusting rods 36 are provided on both sides of the bracket 35, and the gears 321 are mounted on the adjusting rods 36, and the position of the gears 321 on the adjusting rods 36 is adjustable; the position of the support rod 21 on the adjusting shaft 211 is also adjustable, thereby adjusting the distance between the two support rods 21 and the two gears 321 according to the length of the roller 22.

[0033] See Figure 2 In this embodiment of the painting device, the first grip 31 includes a first sleeve 311 and a first telescopic rod 312. The first sleeve 311 is fixed to the bracket 35, and the first telescopic rod 312 is telescopically disposed within the first sleeve 311 to adjust the length of the first grip 31. A first bolt 313 is provided on the first sleeve 311. By rotating the first bolt 313, the first telescopic rod 312 can be released or fixed, thereby adjusting the length of the first telescopic rod 312. Adjusting the length of the first grip 31 can also help the user better adapt to different painting environments. For example, when painting higher or harder-to-reach areas, the user can increase the length of the first grip 31 to get closer to the painting area, improving work efficiency.

[0034] See Figure 3In this embodiment of the coating device, the storage tank 1 is further provided with a second gripping rod 12. The second gripping rod 12 includes a second sleeve rod 121 and a second telescopic rod 122. The second sleeve rod 121 is fixed to the wall of the storage tank 1, and the second telescopic rod 122 is telescopically disposed within the second sleeve rod 121 to adjust the length of the second gripping rod 122. A second bolt 123 is provided on the second sleeve rod 121. By rotating the second bolt 123, the second telescopic rod 122 can be released or fixed, thereby adjusting the length of the second telescopic rod 122. By adjusting the length of the second gripping rod 12, the user can more easily control the overall height and tilt angle of the coating device, thereby more accurately positioning the coating area. The second gripping rod 12 and the first gripping rod 31 are located in different parts of the coating device, respectively, and together provide the user with better balance and stability, making the coating process more stable and uniform.

[0035] See Figure 1 In this embodiment of the coating device, the bottom of the second telescopic rod 122 is provided with a plurality of anti-slip grooves 13 at intervals along its length. The anti-slip grooves 13 are used to prevent the hand from slipping when gripping the second handle 122 during operation. The anti-slip grooves 13 can increase the friction between the hand and the second telescopic rod 122, thereby preventing slippage due to sweaty, wet, or excessive force during operation.

[0036] See Figure 1 and Figure 3 In this embodiment of the coating apparatus, the storage tank 1 is further provided with a feed inlet 14, which is arranged opposite to the discharge outlet 11. A sealing cover 15 is provided on the feed inlet 14, which is detachably provided and is used to seal the feed inlet 14. The detachable sealing cover 15 allows the user to easily open the feed inlet 14 to perform necessary maintenance when cleaning or changing the coating material.
