Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary tools and equipment for coating application, and in particular to a coating roller brush. Background Technology
[0002] In painting applications, roller brushes are common painting tools. They achieve even coating by rolling the brush body to pick up paint and then rolling it across the wall. However, existing roller brushes often have a large gap between the roller body and the support frame, allowing paint to easily seep into this gap. This not only wastes paint but also affects the evenness of the coating due to paint accumulation during rolling, and can even cause the roller to jam or rotate poorly, reducing work efficiency. Furthermore, the seeped paint may dry and adhere to the support frame, further increasing rolling resistance. This often means that roller brushes can only be used once and cannot be reused, increasing work costs. Utility Model Content

[0027] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0028] Example 1
[0029] Reference Figure 1 and Figure 2 This embodiment provides a paint roller brush, including a Y-shaped bracket 1, a handle 2 and a brush body 3. The bracket 1 has two ends that are arranged opposite to each other. The brush body 3 is rotatably connected between the two ends of the bracket 1, and the handle 2 is fixedly connected to the third end of the bracket 1.
[0030] The brush body 3 has connectors 7 at both ends, and the bracket 1 has mounting seats 4 at both ends. The mounting seats 4 mate with the connectors 7 to form a rotatable connection between the bracket 1 and the brush body 3. For details, refer to [reference needed]. Figures 2-6 The connector 7 includes a connecting rod 72, and the mounting base 4 is provided with a connecting groove 41 for matching the connecting rod 72. The connecting rod 72 is located inside the connecting groove 41 to form a rotational connection between the mounting base 4 and the connector 7.
[0031] One end of the bracket 1 has a mounting base 4 fixedly connected to it, and the other end has a mounting base 4 connected to it via a movable component 5. The movable component 5 allows the mounting base 4 to move relative to the bracket 1, adjusting the distance between the two mounting bases 4 to facilitate the installation of the brush body 3 between them. (Refer to...) Figure 6 The movable component 5 includes a pull rod 51, an elastic element 52, a limiting plate 53, and a connecting seat 54. One end of the connecting seat 54 is fixedly connected to the mounting base 4, and the other end of the connecting seat 54 is fixedly connected to the pull rod 51. One end of the pull rod 51 passes through the bracket 1 and is fixedly connected to the starting block 6. The starting block 6 and the mounting base 4 are located on opposite sides of the end of the bracket 1. An elastic element 52 is sleeved on the outside of the pull rod 51. The elastic element 52 is located between the bracket 1 and the connecting seat 54. The extension tendency of the elastic element 52 brings the two mounting bases 4 closer together. A sliding groove is provided on the bracket 1. A limiting plate 53 is fixedly connected to the side of the connecting seat 54. Both the pull rod 51 and the limiting plate 53 are located inside the sliding groove. The sliding groove limits the positioning of the limiting plate 53, and the limiting plate 53 forms a sliding connection with the bracket 1. The pull rod 51 and the limiting plate 53 can move relative to the bracket 1, forming a sliding connection between the connecting seat 54 and the bracket 1.
[0032] When it is necessary to remove the brush body 3, pull the starting block 6 away from the mounting base 4 to increase the distance between the two mounting bases 4. The connecting rods 72 at both ends of the brush body 3 can then disengage from the connecting grooves 41 of the mounting base 4, thus removing the brush body 3. When it is necessary to install the brush body 3, pull the starting block 6 away from the mounting base 4 to increase the distance between the two mounting bases 4. Place the two ends of the brush body 3 between the two mounting bases 4, release the starting block 6, and the elastic element 52 will bring the two mounting bases 4 closer together. The connecting rods 72 at both ends of the brush body 3 can then be inserted into the connecting grooves 41 of the mounting base 4, thus installing the brush body 3.
[0033] refer to Figures 3-7The connector 7 also includes a first sealing sleeve 71 located outside the connecting rod 72, and the first sealing sleeve 71 is coaxially arranged with the connecting rod 72. One end face of the first sealing sleeve 71 is fixedly connected to the brush body 3, and the other end face of the first sealing sleeve 71 is the connecting end face. A limiting sleeve 42 is provided on the mounting base 4, and the limiting sleeve 42 is located outside the mounting base 4. The end face of the limiting sleeve 42 matches the connecting end face of the first sealing sleeve 71. When the mounting base 4 is engaged with the connector 7, the connecting end face of the first sealing sleeve 71 is in contact with the end face of the limiting sleeve 42 to achieve a seal on the outside of the joint surface between the mounting base 4 and the connector 7, reducing the probability of paint entering the joint surface between the connecting rod 72 and the connecting groove 41.
[0034] Furthermore, the end face of the first sealing sleeve 71 and the end face of the limiting sleeve 42 can be corresponding planes or stepped surfaces. In this embodiment, the mating end face of the first sealing sleeve 71 is provided with an annular stepped surface, which includes an outer first end face 711 and an inner second end face 712, with the second end face 712 being recessed relative to the first end face 711. The limiting sleeve 42 is provided with a corresponding annular double stepped surface to match the annular stepped surface of the first sealing sleeve 71. The stepped mating surface can effectively improve the sealing effect between the first sealing sleeve 71 and the limiting sleeve 42.
[0035] refer to Figure 7 A material storage groove 43 is provided between the annular double-stepped surfaces of the limiting sleeve 42. When paint enters between the limiting sleeve 42 and the first sealing sleeve 71, the material storage groove 43 can be used to store a small amount of paint, relieving the pressure and flow tendency of paint entering the mating surface of the connecting rod 72 and the connecting groove 41. When replacing the brush body 3, the material storage groove 43 can be cleaned to maintain its storage capacity.
[0036] refer to Figure 4 and Figure 5 In this embodiment, a second protruding ring 713 is provided on the first end face 711, and a third protruding ring 714 is provided on the second end face 712. The end face of the limiting sleeve 42 is provided with annular grooves corresponding to the second protruding ring 713 and the third protruding ring 714, which can further improve the sealing effect between the first sealing sleeve 71 and the limiting sleeve 42.
[0037] Example 2
[0038] Compared with Embodiment 1, in this embodiment, the reference Figures 2-6 A second sealing sleeve 73 is also provided outside the first sealing sleeve 71. The second sealing sleeve 73 is coaxially arranged with the first sealing sleeve 71 and is located between the two ends of the first sealing sleeve 71. The limiting sleeve 42 is provided with a corresponding annular three-step surface to match the end faces of the first sealing sleeve 71 and the second sealing sleeve 73.
[0039] Furthermore, a first protruding ring 731 is provided on the end face of the second sealing sleeve 73. An annular groove corresponding to the first protruding ring 731 is provided on the end face of the limiting sleeve 42. The first protruding ring 731, the second protruding ring 713, and the third protruding ring 714 are arranged sequentially from the outside to the inside to enhance the sealing effect between the first sealing sleeve 71 and the limiting sleeve 42.
[0040] Therefore, the working principle of this utility model embodiment is as follows:
[0041] (1) The brush body 3 of the paint roller brush is rotatably connected between two mounting seats 4. The two connectors 7 of the brush body 3 are provided with first sealing sleeves 71. When the connecting rod 72 is engaged with the connecting groove 41 of the mounting seat 4, the brush body 3 and the mounting seat 4 are rotatably connected. The end face of the first sealing sleeve 71 is in contact with the end face of the limiting sleeve 42 on the mounting seat 4, forming a seal on the outside of the mounting seat 4, which can reduce the probability of paint entering the joint surface between the connecting rod 72 and the connecting groove 41. A stepped joint surface is provided between the first sealing sleeve 71 and the limiting sleeve 42, and a raised ring is also provided on the stepped joint surface, thereby improving the sealing effect between the first sealing sleeve 71 and the limiting sleeve 42.
[0042] (2) In addition, by adding a coaxial second sealing sleeve 73 outside the first sealing sleeve 71, and using the convex ring design to cooperate with the three-step surface of the limiting sleeve 42 to form an additional sealing layer, the sealing effect can be further enhanced.
[0043] In summary, this utility model improves the connection design between the brush body and the bracket, and forms a multi-level sealing structure through the cooperation of the sealing sleeve and the limiting sleeve. This effectively solves the problems of paint seeping into the connection between the bracket and the brush body during the coating process of existing roller brushes, which leads to paint waste, uneven coating and roller jamming.
