Description

Technical Field

[0001] The utility model relates to a coating device, in particular to a coating device. Background Art

[0002] Paint, traditionally known as paint in China, is a viscous liquid applied to the surface of an object to be protected or decorated, and can form a firmly adhered continuous film with the coated object. It is usually based on resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. The smear brush, also known as the paint film or coating paint brush, is composed of a handle and fine bristles or velvet. A paint smearing device is required when applying paint.

[0003] The patent for a paint application device for exterior walls of construction projects is published with the announcement number CN212534943U. The patent includes a support rod, a fixed housing fixed to the top of the support rod, and a connecting rod connected to the middle of the fixed housing via a disassembly device. The disassembly device includes a fixed plug, a protective cushion, a connecting plate, a handle, a slide, a connecting block, a fixed block, and a spring. The outer wall of the connecting rod is fixed with a coating device body. The utility model is provided with a coating device body, a fixed plug, a connecting plate, a handle, a hinged rod, a slider, a slide, a connecting block, and a spring, which allows for relatively convenient replacement of the coating device body, thereby ensuring the working efficiency of the device. At the same time, the support rod, the fixed housing, the coating device body, and the protective housing are provided, which allows for relatively stable coating of exterior walls, avoiding the situation in which traditional coating devices, which may cause low working efficiency due to paint dripping during use, ensures the practicality of the device.

[0004] However, since the protective shell is fixed on the support rod, this patent makes it inconvenient to disassemble and clean the protective shell. In addition, when painting the wall, it is usually necessary to tilt the painting brush at a certain angle and roll it on the wall. However, since the diameter of the protective shell is too large, the protective shell can easily scratch the wall during the painting process, causing damage to the wall, and the practicality is not high.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0024] like Figures 1 to 4 As shown, the utility model is a paint application device, comprising a support rod 1, a paint brush rod 2 detachably mounted on the support rod 1, a threaded groove being provided on the top of the support rod 1, and an external thread matching the threaded groove on the top of the support rod 1 on the bottom of the paint brush rod 2. The paint brush rod 2 is connected to the support rod 1 through a threaded connection, which facilitates the disassembly of the paint brush rod 2 from the support rod 1 and the replacement of the paint brush rod 2 when applying paints of different colors.

[0025] A material receiving box 3 mounted on the support rod 1 to prevent paint from dripping, and a positioning component 4 to facilitate quick disassembly and assembly of the material receiving box 3;

[0026] The positioning assembly 4 includes: a positioning sleeve 401 fixedly installed on the material receiving box 3, a mounting sleeve 402 fixedly installed on the top of the support rod 1, symmetrical limiting grooves 403 opened on both sides of the positioning sleeve 401, a limiting rod 404 passing through both sides of the mounting sleeve 402 and extending one end to the inside of the adjacent limiting groove 403, a spring 406 sleeved on the limiting groove 403, one end of the spring 406 is fixedly connected to the inner wall of the mounting sleeve 402, and the other end of the spring 406 is fixedly connected to the surface of the pressure block 405, and is fixedly connected to the pressure block 405 fixedly installed at the end of the limiting rod 404.

[0027] When installing between the smear brush rod 2 and the support rod 1, first, the material receiving box 3 is installed on the top of the support rod 1 through the middle positioning sleeve 401. At this time, when the smear brush rod 2 and the support rod 1 are threadedly installed, the smear brush rod 2 is convenient for squeezing the two symmetrical limit grooves 403 to move in opposite directions through the curved surface at the bottom, so that one end of the limit groove 403 extends to the inside of the corresponding installation sleeve 402, completing the locking of the position of the positioning sleeve 401, and realizing the installation and fixation of the material receiving box 3. When the smear brush rod 2 is removed, the spring 406 drives the pressure block 405 at the end of the limit rod 404 to reset and release the lock of the positioning sleeve 401, thereby facilitating the quick disassembly and assembly of the material receiving box 3, and further facilitating the cleaning of the smear brush rod 2 and the material receiving box 3.

[0028] The side of the pressure block 405 close to the smear brush rod 2 is set as an inclined surface, and the bottom of the smear brush rod 2 is set as an arc surface that matches the inclined surface of the pressure block 405. When the smear brush rod 2 is installed inside the support rod 1, the smear brush rod 2 passes through the arc surface at the bottom to facilitate the opposite movement of the two symmetrical limit grooves 403 by squeezing.

[0029] A guide component 301 is fixedly installed inside the material receiving box 3 to guide the dripping paint;

[0030] The guide component 301 includes: a connecting frame 3011 fixedly mounted on the material receiving box 3, a guide plate 3012 fixedly mounted on the top of the connecting frame 3011, the guide plate 3012 is arc-shaped, and the guide plate 3012 is located directly below the smear brush. Since the guide plate 3012 is located directly below the smear brush, when the smear brush rod 2 is slightly tilted at a certain angle to paint the wall, the guide plate 3012 is prevented from scratching the wall, thereby improving practicality. Moreover, the arc-shaped setting of the guide plate 3012 facilitates the paint dripping on the guide plate 3012 to move closer to the middle of the through groove 3013, thereby better collecting the paint and the through groove 3013 opened on the guide plate 3012. Since the guide plate 3012 is located directly below the paint brush, when the paint brush rod 2 is painting, the paint drips onto the guide plate 3012, and the through groove 3013 opened in the middle of the guide plate 3012 gathers and guides the dripping paint to the middle for better collection in the interior of the receiving box 3.

[0031] Working principle: When applying paint of different colors and needing to replace the installed smear brush rod 2, or disassembling and cleaning the smear brush rod 2 and the material receiving box 3, first put the material receiving box 3 on the top of the support rod 1 through the middle positioning sleeve 401. At this time, when the smear brush rod 2 and the support rod 1 are threadedly installed, the smear brush rod 2 is convenient for squeezing the two symmetrical limit grooves 403 to move in opposite directions through the curved surface at the bottom, so that one end of the limit groove 403 extends to the inside of the corresponding installation sleeve 402, completing the locking of the position of the positioning sleeve 401, and realizing the installation and fixation of the smear brush rod 2 and the material receiving box 3. When the smear brush rod 2 is removed, the spring 406 drives the pressure block 405 at the end of the limit rod 404 to reset and release the lock of the positioning sleeve 401, thereby facilitating the quick disassembly and assembly of the smear brush rod 2 and the material receiving box 3, and further facilitating the cleaning of the smear brush rod 2 and the material receiving box 3.
