[0002] There are many different building materials used in building construction. These materials include wood, bamboo, stone, cement, concrete, metal, bricks and tiles, engineering plastics, and composite materials. When materials are directly exposed to the atmosphere, they are subject to various corrosive factors, mechanical impacts, scratches, and wind and sand corrosion. Therefore, they need to be coated for protection.

[0003] According to the search, a building waterproofing spraying machine with announcement number CN219411682U has a connecting pipe installed at the bottom of the material tank. The connecting pipe is connected to the input end of the material pump. The material pump is fixedly connected to the surface of the base plate. The output end of the material pump is connected to the spraying pipe. A spray gun is installed at one end of the spraying pipe. The spring and scraper are designed to keep the scraper in contact with the inner wall of the mixing tank, so as to scrape off the paint adhering to the inner wall of the mixing tank.

[0004] To improve the ease of spraying operations, the spray hose connected to the spray gun is usually selected as a flexible hose with high bending capacity, which is convenient for working in confined spaces or when the spraying distance needs to be changed. However, in actual storage or use of spraying equipment, the hose is easily placed messily on the ground, which is easily stepped on, affecting the delivery of paint and the life of the hose. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a building decoration spraying device that solves the problem that in actual storage or use of spraying devices, the hoses are easily placed messily on the ground, which are easily stepped on, affecting the delivery of paint and the life of the hoses.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A building decoration spraying device includes a trolley, a liquid storage container placed on the top of the trolley, a liquid pump fixedly installed on the top of the trolley and located on one side of the liquid storage container, the input end of the liquid pump being connected to the inner cavity of the liquid storage container through a bend pipe, the output end of the liquid pump being connected to a spray gun through a hose, and a retraction assembly for adjusting the length of the hose being installed on the top of the trolley.

[0009] The gathering assembly includes a gathering box disposed on one side of the liquid pump, and the gathering box has a rectangular hollow structure. A through hole is opened in the wall of the gathering box for the hose to pass through. A drive motor is installed on the top of the gathering box. A threaded rod is fixedly installed on the output end of the drive motor, and the bottom end of the threaded rod is rotatably connected to the inner bottom wall of the gathering box through a bearing. A lifting plate is threadedly connected to the threaded rod. A C-shaped clamping block is integrally formed and connected to the outer wall of the lifting plate. The middle section of the hose passes through the C-shaped clamping block.

[0010] Preferably, the inner cavity of the collection box is symmetrically provided with limit rods, and the limit rods move through the wall of the lifting plate.

[0011] Preferably, the liquid storage container includes a cylinder placed on a trolley, a sealing cap is installed at the top opening of the cylinder, a snap-fit ​​groove is provided on the wall of the cylinder, and a locking rod is fixedly installed on the outer wall of the sealing cap.

[0012] Preferably, the top of the cylinder is connected to an elastic element, and multiple elastic elements are arranged in a ring array.

[0013] Furthermore, the snap-fit ​​groove includes an arc segment and a vertical segment connected to the end of the arc segment. When the sealing cap is installed on the cylinder, the locking rod is located within the vertical segment of the snap-fit ​​groove.

[0014] Preferably, a protective frame is fixedly installed on the trolley, and a placement seat is fixedly installed on the outer wall of the protective frame, and the shape of the placement seat is adapted to the shape of the spray gun.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. In this utility model, during spraying, the drive motor is controlled to rotate the threaded rod according to the actual length of the hose required. The lifting plate moves the middle section of the hose up or down, thereby shortening or lengthening the retractable part of the hose. This allows for hose length adjustment, preventing the hose from being placed haphazardly on the ground and trampled on, which would affect the delivery of paint and the lifespan of the hose.

[0017] 2. In this utility model, during installation, the sealing cover is placed on the cylinder using the handle on the top of the sealing cover, and the locking rod is aligned with the arc segment of the snap-fit ​​groove. Pressure is applied downward to the sealing cover, causing the locking rod to move along the outer wall of the snap-fit ​​groove to the end of the arc segment and compress the elastic element. At this time, the pressure on the sealing cover is released, and under the reset action of the elastic element, the sealing cover is pushed upward, causing the locking rod to move to the top of the vertical segment, thereby locking the sealing cover onto the cylinder as a whole, further improving the sealing performance of the paint storage.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a building decoration spraying device.

[0027] This utility model provides, for example Figure 1-4 The architectural decoration spraying device shown includes a trolley 1, a liquid storage container 2 placed on the top of the trolley 1, a liquid pump 3 fixedly installed on the top of the trolley 1, and the liquid pump 3 located on one side of the liquid storage container 2. The input end of the liquid pump 3 is connected to the inner cavity of the liquid storage container 2 through a bend 4, and the output end of the liquid pump 3 is connected to a spray gun 6 through a hose 5. A retracting assembly 7 for adjusting the length of the hose 5 is installed on the top of the trolley 1.

[0028] The gathering assembly 7 includes a gathering box 701 disposed on one side of the liquid pump 3. The gathering box 701 has a rectangular hollow structure. A through hole 702 is provided in the wall of the gathering box 701 for the hose 5 to pass through. A drive motor 703 is installed on the top of the gathering box 701. A threaded rod 704 is fixedly installed at the output end of the drive motor 703. The bottom end of the threaded rod 704 is rotatably connected to the inner bottom wall of the gathering box 701 through a bearing. A lifting plate 705 is threadedly connected to the threaded rod 704. A C-shaped clamping block 706 is integrally formed on the outer wall of the lifting plate 705. The middle section of the hose 5 passes through the C-shaped clamping block 706. The two ends of the C-shaped clamping block 706 are set as arc surfaces to avoid excessive bending of the hose 5.

[0029] Specifically, the spray gun 6 and the drive motor 703 are electrically connected to an external power supply via wires and a control switch. During spraying, the drive motor 703 drives the threaded rod 704 to rotate according to the required length of the hose 5. The lifting plate 705 moves the middle section of the hose 5 up or down, thereby shortening or lengthening the retractable part of the hose 5. This allows for length adjustment of the hose 5, preventing it from being placed haphazardly on the ground and trampled on, which would affect the delivery of the paint and the lifespan of the hose 5.

[0030] like Figure 2 As shown, the inner cavity of the gathering box 701 is symmetrically provided with limiting rods 707, and the limiting rods 707 are movably inserted through the wall of the lifting plate 705, so that the lifting plate 705 can only slide up or down along the axis of the limiting rods 707, thus preventing the lifting plate 705 from deflecting during movement.

[0031] For the practicality of this device, such as Figure 1 As shown, a protective frame 8 is fixedly installed on the upper part of the trolley 1. A door frame is hinged to one side of the protective frame 8, which makes it easy to remove the liquid storage container 2 when cleaning is required later. A placement seat 9 is fixedly installed on the outer wall of the protective frame 8, and the shape of the placement seat 9 is adapted to the shape of the spray gun 6. The placement seat 9 makes it easy to place the spray gun 6 when not in use, so as to avoid the spray gun 6 being damaged by being stepped on.

[0032] In order to improve the functionality of this device, such as Figure 4 As shown, the liquid storage container 2 includes a cylindrical body 201 placed on a trolley 1. A sealing cap 202 is installed at the top opening of the cylindrical body 201. A snap-fit ​​groove 203 is provided on the wall of the cylindrical body 201. A locking rod 204 is fixedly installed on the outer wall of the sealing cap 202. The snap-fit ​​groove 203 includes an arc segment and a vertical segment connected to the end of the arc segment. When the sealing cap 202 is installed on the cylindrical body 201, the locking rod 204 is located in the vertical segment of the snap-fit ​​groove 203. An elastic element 205 is connected to the top of the cylindrical body 201, and multiple elastic elements 205 are arranged in a ring array.

[0033] Specifically, to meet practical requirements, the elastic element 205 is preferably a spring; the sealing cap 202 is installed on the top of the cylinder 201 to prevent the components in the coating from gradually evaporating over time, thus causing changes in the concentration and performance of the coating; during installation, the sealing cap 202 is placed on the cylinder 201 using the handle on the top of the sealing cap 202, and the locking rod 204 is aligned with the arc segment of the snap-fit ​​groove 203. Pressure is applied downward to the sealing cap 202, causing the locking rod 204 to move along the outer wall of the snap-fit ​​groove 203 to the end of the arc segment and compress the elastic element 205. At this time, the pressure on the sealing cap 202 is released, and under the reset action of the elastic element 205, the sealing cap 202 is pushed upward, causing the locking rod 204 to move to the top of the vertical segment, thereby locking the sealing cap 202 onto the cylinder 201 as a whole, further improving the sealing performance of the coating storage.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
