Technical Field

[0001] This utility model relates to the field of latex paint roller brush technology, specifically a latex paint flat coating device. Background Technology

[0002] Latex paint is a common name for latex coatings, which are widely used for interior and exterior wall decoration of buildings. A roller is a professional tool for decoration and renovation, and its materials are mostly engineering plastics and fibers, but some are made of natural wool fabric. Flat coating is a technique for beautifying walls. Workers usually use latex paint rollers to apply a flat coating to walls. Existing rollers come in different sizes for painting different areas of the wall. For example, a large roller is needed for large living room walls, while a small roller is needed for corners such as light switches to avoid incomplete painting. Therefore, people usually buy rollers of various sizes to deal with different areas. Once a roller of a certain size has finished painting one area, it is usually discarded because it is not suitable for painting other areas, which is very troublesome and wasteful of resources. Therefore, a latex paint flat coating device is proposed. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a latex paint flat coating device.

[0023] Example:

[0024] Combination Figure 1-6 As shown, this utility model provides a latex paint flat coating device, including a connector 1. A mounting groove 2 is provided on one side of the connector 1, and an adjusting rod 3 is threadedly connected inside the mounting groove 2. The adjusting rod 3 can be adjusted in length according to the on-site construction conditions. This is an existing structure that facilitates the overall device to flat coat the wall surface, avoiding incomplete coating. A clearance hole 21 is provided at one end of the connector 1, and a first support frame 4 is sleeved inside the clearance hole 21. A first threaded rod 5 is provided at one end of the first support frame 4, and a first limiting ring 6 is fixedly installed on the surface of the first support frame 4. Under the action of the first limiting ring 6, the first support frame 4 is limited to the connecting part. In component 1, the first support frame 4 is fixed in the connector 1 in conjunction with the first handle 7 to prevent loosening and falling off, which would prevent painting. One end of the first support frame 4 is threadedly connected to the first handle 7, and a second limiting ring 8 is fixedly installed on one end of the first support frame 4. During installation, it can be snapped on according to the position of the second limiting ring 8. A small roller brush 9 is movably sleeved on one end of the first support frame 4. The small roller brush 9 is used to be fully coated with latex paint and used to paint the wall. The small roller brush 9 is suitable for areas that are difficult to paint, such as power switches or corners, to avoid incomplete painting. A threaded groove 10 is opened on one end of the small roller brush 9.

[0025] The connector 1 has a U-shaped groove 11 on its surface. A fastener 13 is slidably connected to the top of the U-shaped groove 11. A spring 12 is fixedly connected to the top of the fastener 13. The top of the spring 12 is fixedly connected to the connector 1. Slide rails 14 are provided on both sides of the fastener 13. A clearance groove is provided at the top of the U-shaped groove 11. The clearance groove is slidably connected to the slide rails 14. That is, when the fastener 13 is squeezed, it will slide upward into the clearance groove under the action of the slide rails 14. Then, it will rebound and reset under the pressure of the spring 12, locking the part in the U-shaped groove 11 for initial positioning.

[0026] Furthermore, a second support frame 15 is fitted inside the U-shaped groove 11. One end of the second support frame 15 is provided with a second threaded rod 16. The structure and function of the second threaded rod 16 are identical to those of the first threaded rod 5, so they will not be described in detail. A third limiting ring 17 is fixedly installed on the surface of the second support frame 15. The first limiting ring 6 and the third limiting ring 17 have the same structure and are used to limit the second support frame 15 within the connecting member 1. One end of the second threaded rod 16 is threadedly connected to a second handle 18. The third limiting ring 17 then cooperates with the second handle 18 to fix the second support frame 15 in the connecting member 1, preventing the second support frame 15 from falling off and causing the device to malfunction. The second support frame 15 has a medium-sized roller brush 19 movably sleeved at one end. The medium-sized roller brush 19 is of normal specifications and has the same purpose as the small roller brush 9. It is used to coat the wall with latex paint. Workers can hold it for close-range painting and make fine-tuning of some details to avoid unqualified painting. One end of the medium-sized roller brush 19 is equipped with a bolt 20, one end of which is threaded into the threaded groove 10. The small roller brush 9 and the medium-sized roller brush 19 fit tightly together. When the device is not separated, the small roller brush 9 and the medium-sized roller brush 19 form a whole, namely a large roller brush. With the help of the adjusting rod 3, a large area of ​​the wall can be painted, improving efficiency.

[0027] The working principle and usage process of this utility model are as follows: First, when assembly is required, the first handle 7 is unscrewed from the first threaded rod 5. At this time, the first support frame 4 is fitted into the clearance hole 21, and then the first handle 7 is screwed into the first threaded rod 5. The first handle 7 and the first limiting ring 6 cooperate to fix the first support frame 4 in the connector 1. At this time, the second handle 18 is unscrewed, and the second support frame 15 is fitted into the U-shaped groove 11. Under the action of the fastening part 13, the initial limiting is completed. Then, the second handle 18 is rotated again, so that under the action of the second handle 18 and the third limiting ring 17, the second support frame 15 is fixed in the connector 1. At this time, the medium-sized roller brush cylinder 19 is rotated, and the bolt 20 at one end of the medium-sized roller brush cylinder 19 is connected to the threaded groove 10 at one end of the small roller brush cylinder 9. At this time, the fixing is completed.
