Description

Technical Field

[0001] This utility model relates to the technical field of spray painting devices, specifically a spray painting device for building wall decoration. Background Technology

[0002] In home decoration work, painting work on surfaces such as walls and ceilings has always been a part with a large workload and requires a lot of skill. Therefore, the paint spraying equipment is the core component for carrying out paint spraying. Traditional spraying equipment generally uses a spray gun to spray paint onto the wall surface, but there are still some problems.

[0003] For example, patent document CN208161881U discloses: "A spray painting device. This spray painting device is used for paint spraying in home decoration, including: a nozzle, a pumping mechanism capable of conveying and pressurizing fluid, an overflow valve, a motor, a battery pack, and a liquid storage tank; when the spraying area is small, the user can hold the entire device for spraying; when the spraying area is large, the nozzle can be connected to the pumping mechanism via a high-pressure pipe, in which case the user only needs to hold the nozzle part for spraying. According to the embodiments of this disclosure, on the one hand, it overcomes the limitation of AC power supply." On the other hand, it satisfies the ease of use of the painting device under different spraying area requirements. By adapting the painting device to the applicable working conditions, when the area to be sprayed is small, each of the nozzle, pumping mechanism, transmission mechanism, motor, battery pack and liquid tank can be directly installed into the housing to form an integrated handheld device. When the spraying area is large and multiple paint additions are required, the nozzle can be separated from the housing and connected to the housing and liquid tank via a high-pressure pipe. On the one hand, it overcomes the limitation of AC power supply, and on the other hand, it satisfies the ease of use of the painting device under different spraying area requirements.

[0004] However, when the nozzles of the above-mentioned devices spray paint, the amount of paint sprayed is difficult to control because the paint spraying is manually controlled. This can easily lead to excessive paint being sprayed out, causing excess paint to drip onto the ground, resulting in poor cleanliness and paint waste. Therefore, a paint-recycling spraying device is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a spray painting device for building wall decoration, so as to solve the problem mentioned in the background art that excess paint easily drips onto the ground and causes waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spray painting device for architectural wall decoration, comprising: a spray gun, a fixed frame fixedly connected to the front end of the spray gun, a first fixed ring overlapping the top of the fixed frame, a second fixed ring rotatably connected to the bottom of the first fixed ring, a first baffle fixedly connected to the top of the first fixed ring, a scraper fixedly connected to the front of the first baffle, rollers rotatably connected to both sides of the inner wall of the scraper, a second baffle fixedly connected to the bottom of the second fixed ring, a rotating rod rotatably connected to the inner wall of the front of the second baffle, a roller fixedly connected to one end of the rotating rod, and a storage box slidably connected to the front end of the bottom of the second baffle.

[0007] As a preferred technical solution of this utility model, a connecting shell is fixedly connected to the middle of the back of the storage box, and a bolt is threadedly connected to the inner wall of the connecting shell, with the top of the bolt inserted into the inner wall of the second baffle.

[0008] As a preferred embodiment of this utility model, a first connecting box is fixedly connected to one side of the first fixing ring, and a second connecting box is fixedly connected to one side of the second fixing ring.

[0009] As a preferred embodiment of the present invention, a sliding block is slidably connected to the inner wall of the first connecting box, and the surface of the sliding block is slidably connected to the inner wall of the first connecting box. A push-pull block is fixedly connected to the front of the sliding block.

[0010] As a preferred embodiment of this utility model, a connecting block is fixedly connected to the bottom of the sliding block, and a plug-in block is fixedly connected to one side of the bottom of the connecting block, and the plug-in block is made of steel.

[0011] As a preferred embodiment of this utility model, a magnet is fixedly connected to the inner wall of the second connecting box, and the surface of the plug block is magnetically connected to the surface of the magnet.

[0012] As a preferred embodiment of this utility model, the material of the roller surface is cotton, and the front of the roller and the roller wheel are on the same vertical line.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 A spray painting device for building wall decoration:

[0025] Includes: a spray gun 1, a fixed frame 2 fixedly connected to the front end of the spray gun 1, a first fixed ring 3 overlapping the top of the fixed frame 2, a second fixed ring 4 rotatably connected to the bottom of the first fixed ring 3, a first baffle 5 fixedly connected to the top of the first fixed ring 3, a scraper 6 fixedly connected to the front of the first baffle 5, rollers 7 rotatably connected to both sides of the inner wall of the scraper 6, a second baffle 8 fixedly connected to the bottom of the second fixed ring 4, a rotating rod 9 rotatably connected to the inner wall of the front of the second baffle 8, a roller 10 fixedly connected to one end of the rotating rod 9, and a storage box 11 slidably connected to the front end of the bottom of the second baffle 8.

[0026] When using this device to recycle excess paint, the worker holds the spray gun 1, points it towards the wall, and makes the roller 7 and the cylinder 10 fit against the wall. Then, the paint is sprayed out through the spray gun 1 and lands on the wall. The spray gun 1 is then moved vertically, causing the roller 7 and the cylinder 10 to roll on the wall surface. At this time, the scraper 6 scrapes off the excess paint from the wall, causing the excess paint to fall into the cylinder 10. After the cylinder 10 is wetted, the paint inside the cylinder 10 drips down. The opening at the top of the collection box 11 is located at the bottom of the cylinder 10, allowing the paint to drip down through the bottom of the cylinder 10 into the collection box 11, thus completing the collection and recycling of excess paint and reducing the probability of paint falling on the ground.

[0027] Please see Figure 3 , Figure 4 A connecting shell 12 is fixedly connected to the middle of the back of the storage box 11. A bolt 13 is threadedly connected to the inner wall of the connecting shell 12, and the top of the bolt 13 is inserted into the inner wall of the second baffle 8.

[0028] When installing the storage box 11 using this device, place the storage box 11 on one side of the bottom of the second baffle 8, then slide the T-shaped sliding rod at the bottom of the second baffle 8 into the T-shaped sliding groove at the top of the storage box 11, and then rotate the bolt 13 so that the bolt 13 rotates and is inserted into the inner wall of the second baffle 8, thereby completing the installation and fixing of the storage box 11.

[0029] Please see Figure 1 , Figure 5 and Figure 6 A first connecting box 14 is fixedly connected to one side of the first fixing ring 3, and a second connecting box 15 is fixedly connected to one side of the second fixing ring 4. A sliding block 16 is slidably connected to the inner wall of the first connecting box 14, and the surface of the sliding block 16 is slidably connected to the inner wall of the first connecting box 14. A push-pull block 17 is fixedly connected to the front of the sliding block 16, and a connecting block 18 is fixedly connected to the bottom of the sliding block 16. A plug-in block 19 is fixedly connected to one side of the bottom of the connecting block 18, and the plug-in block 19 is made of steel. A magnet 20 is fixedly connected to the inner wall of the second connecting box 15, and the surface of the plug-in block 19 is magnetically connected to the surface of the magnet 20.

[0030] When fixing the fixing ring using this device, the second fixing ring 4 is attached to the bottom of the fixing frame 2, and then the first fixing ring 3 is rotated to the top of the fixing frame 2. At this time, the push-pull block 17 is pushed, causing the push-pull block 17 to move the sliding block 16 on one side. The sliding block 16 moves the connecting block 18 at the bottom, and the connecting block 18 moves the plug-in block 19 on one side. Then the first connecting box 14 and the second connecting box 15 are attached together. Then the push-pull block 17 is pushed in the opposite direction, so that the plug-in block 19 is inserted into the inner wall of the second connecting box 15 and magnetically fixed with the magnet 20, thereby completing the connection and fixing of the first connecting box 14 and the second connecting box 15.

[0031] The working principle is as follows: the second fixing ring 4 is attached to the bottom of the fixing frame 2, the first fixing ring 3 is rotated, and the plug block 19 is moved to one side. Then, the first connecting box 14 and the second connecting box 15 are attached together, and the plug block 19 is pushed in the opposite direction so that the plug block 19 is magnetically attracted and fixed to the magnet 20, thus completing the installation of the device. Then, the roller 7 and the roller 10 are attached to the ground, and the paint is sprayed out through the spray gun 1. When a lot of paint is sprayed out, the scraper 6 scrapes the paint downwards to scrape the excess paint downwards. At this time, the excess paint slides into the roller 10 and drips into the inside of the collection box 11, thus completing the recycling of the paint and preventing excess paint from falling to the ground, which would result in poor ground cleanliness. Then, the bolt 13 is rotated so that the bolt 13 extends out of the second baffle 8. At this time, the collection box 11 is detached from the fixing. Then, the collection box 11 is slid to both sides so that the paint inside can be recycled and reused.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
