Description

Technical Field

[0001] This utility model relates to the field of brush accessories, and more particularly to brush baffles. Background Technology

[0002] Traditional brush baffles typically use a fixed clamping structure, which can only hold brush handles of a single width and thickness. This results in different sizes of brushes requiring dedicated baffles, leading to poor versatility. Utility Model Content

[0003] In view of this, the present invention provides a brush baffle to solve the problems of brush baffles in the prior art.

[0004] To achieve one, some, or all of the above objectives, or other objectives, this utility model proposes:

[0005] A brush baffle, used in conjunction with a brush, includes:

[0006] baffle body;

[0007] A first clamping arm, the first clamping arm including a first connecting end and a first clamping end, the first connecting end being used to connect to the baffle body;

[0008] The second clamping arm includes a second connecting end and a second clamping end. The second connecting end is used to connect to the baffle body. The second clamping arm and the first clamping arm are spaced apart to form a clamping cavity, and the first clamping end and the second clamping end can be far away from or close to each other.

[0009] When the clamping cavity clamps the brush, the distance between the first clamping end and the second clamping end increases, and after the clamping cavity releases the brush, the distance between the first clamping end and the second clamping end decreases, and becomes less than the distance between the first connecting end and the second connecting end.

[0010] In some embodiments, the distance between the first clamping arm and the second clamping arm gradually decreases from the first connecting end to the first clamping end.

[0011] In some embodiments, the first clamping arm and / or the second clamping arm are made of an elastic material.

[0012] In some embodiments, two anti-slip pads are further included, which are installed on the first clamping arm and the second clamping arm in a one-to-one correspondence, and both anti-slip pads are located inside the clamping cavity.

[0034] The second link has one end connected to the external part and the other end connected to the hinge part. The first link and the second link are spaced apart to form a clamping space. When the bracket is in the clamping position, the first clamping arm and the second clamping arm are clamped in the clamping space, and the first link is in contact with the first clamping arm and the second link is in contact with the second clamping arm.

[0035] In some embodiments, it further includes two first limiting slots and two second limiting slots.

Detailed Implementation

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0082] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0083] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0084] See appendix Figure 1 - Appendix Figure 24 This utility model provides a brush baffle, which includes a baffle body 1, a first clamping arm 21 and a second clamping arm 22. The first clamping arm 21 includes a first connecting end 211 and a first clamping end 210, and the first connecting end 211 is used to connect to the baffle body 1. The second clamping arm 22 includes a second connecting end 221 and a second clamping end 220, and the second connecting end 221 is used to connect to the baffle body 1. The second clamping arm 22 and the first clamping arm 21 are spaced apart to form a clamping cavity 200, and the first clamping end 210 and the second clamping end 220 can move away from or close to each other. When the clamping cavity 200 clamps the brush 9, the distance D1 between the first clamping end 210 and the second clamping end 220 increases, and after the clamping cavity 200 releases the brush 9, the distance D1 between the first clamping end 210 and the second clamping end 220 decreases and is less than the distance D2 between the first connecting end 211 and the second connecting end 221.

[0085] like Figures 4-9As shown, this brush baffle is mainly used in conjunction with paintbrushes. These brushes typically include a handle 90, a brush head 91 connected to the end of the handle 90, and bristles 92 on the brush head 91. The brush baffle is used by clamping onto the brush head 91 of the brush 9. Its application scenario is that the brush 9 is used to paint the wall at a corner, which includes the wall surface M1 to be painted and the adjacent protective wall surface M2 (in special cases, the protective wall surface M2 can also be door / window frames, tile surfaces, or other items that do not need painting). The brush baffle, clamped onto the brush head 91, has a plate-like body 1 that isolates the bristles 92 from the protective wall surface M2. This ensures that when the user uses the brush 9 to paint the wall surface M1, paint splattering from the bristles 92 is blocked by the baffle body 1, preventing paint splattering onto the adjacent protective wall surface M2 and avoiding contamination. To allow the brush baffle to fit the brush head 91 of brushes 9 with different thicknesses, the first clamping arm 21 and the second clamping arm 22 are spaced apart on the baffle body 1 to form a clamping cavity 200. Specifically, the clamping cavity 200 is a cavity that extends through both ends, with cavity entrances formed at the first clamping end 210 and the second clamping end 220, facilitating quick installation of the brush baffle onto the brush head 91 of the brush 9. The open clamping cavity 200 also allows the brush baffle to fit brushes of different widths, thus improving its versatility. Both the first clamping arm 21 and the second clamping arm 22 are made of elastic material, allowing the first clamping end 210 and the second clamping end 220 to move away from or close to each other. When the brush baffle is not clamped onto the brush 9, the distance D1 between the first clamping end 210 and the second clamping end 220 is smaller than the distance D2 between the first connecting end 211 and the second connecting end 221. The smaller distance D1 between the first connecting end 210 and the second clamping end 220 allows for clamping of brushes 9 with a smaller thickness. The larger distance D2 between the first connecting end 211 and the second connecting end 221 accommodates brushes with a larger thickness. By applying a force outward from the clamping cavity 200 to the first clamping end 210 and the second clamping end 220, the first clamping end 210 and the second clamping end 220 move away from each other, allowing the brush head 91 of the brush 9 to be inserted into the clamping cavity 200. After the applied force is released, the first clamping end 210 and the second clamping end 220 move closer to each other, allowing the first clamping arm 21 and the second clamping arm 22 to simultaneously and stably clamp the brush head 91 of the brush 9. By setting the interval between the first clamping arm 21 and the second clamping arm 22, the distance between the first clamping end 210 and the second clamping end 220 increases when force is applied and decreases when the force is released, in order to adapt to brushes 9 of different thicknesses and improve the versatility of the brush baffle.In addition, the connection between the brush baffle and the brush 9 is simple. Just place the brush head 91 between the first clamping end 210 and the second clamping end 220, and push the brush baffle and the brush head 91 with force so that the brush head 91 is inserted into the clamping cavity 200, and the brush baffle can be stably clamped on the brush head 91.

[0086] It should also be noted that both the first clamping arm 21 and the second clamping arm 22 adopt a plate-like structure, thereby increasing the contact area with the brush head 91 and improving the stability during clamping. Furthermore, the plate-like structure of the first clamping arm 21 and the second clamping arm 22 makes the overall structure of the brush baffle more robust and less prone to breakage under stress. In other embodiments, one of the first clamping arm 21 and the second clamping arm 22 may be made of an elastic material. A single elastic clamping arm can also change the distance D1 between the first clamping end 210 and the second clamping end 220, allowing the first clamping end 210 or the second clamping end 220 to elastically expand when the brush head 91 is inserted.

[0087] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 12 , Figure 13 and Figure 14 In some embodiments, the distance between the first clamping arm 21 and the second clamping arm 22 gradually decreases from the first connecting end 211 to the first clamping end 210. Specifically, the first clamping arm 21 and the second clamping arm 22 are symmetrically arranged, and the clamping cavity 200 formed by them is a symmetrical chamber. The cross-section of the clamping cavity 200 is U-shaped or conical. In other words, the distance between the first clamping arm 21 and the second clamping arm 22 gradually decreases from the first connecting end 211 to the first clamping end 210. That is, the distance D1 between the first clamping end 210 and the second clamping end 220 constitutes the minimum distance between the first clamping arm 21 and the second clamping arm 22, so that the first clamping arm 21 and the second clamping arm 22 apply the maximum clamping force to the brush 9. The distance D2 between the first clamping arm 21 and the second clamping arm 22 forms the maximum distance between the first clamping arm 21 and the second clamping arm 22, reducing the material stress of the first clamping arm 21 and the second clamping arm 22 at this point and avoiding plastic deformation. The gradually changing distance facilitates the insertion of the brush head 91 into the clamping cavity 200, and allows the inner sides of the first clamping arm 21 and the second clamping arm 22 to have a larger contact area with the surface of the brush head 91 of the brush 9, thereby improving clamping stability. In addition, the clamping cavity 200 with gradually changing inner cavity size further increases the adaptability of the brush baffle to brushes 9 of different widths. When installed on brushes 9 of different widths, the inner sides of the first clamping arm 21 and the second clamping arm 22 can fully contact the brush head 91 to achieve stable clamping.

[0088] Reference Figure 12In some embodiments, the brush baffle also includes two anti-slip pads 3, which are installed one-to-one on the inner sides of the first clamping arm 21 and the second clamping arm 22, and both anti-slip pads 3 are located within the clamping cavity 200. The anti-slip pads 3 are specifically made of materials with a high coefficient of friction, such as silicone rubber, thermoplastic elastomer, or nitrile rubber, to increase the frictional force and improve the clamping stability of the brush baffle on the brush 9. It should also be noted that in other embodiments, a micro-protrusion structure can be provided on the inner surface of the anti-slip pads 3 or the first clamping arm 21 (second clamping arm 22) to increase the frictional force between the first clamping arm 21 (second clamping arm 22) and the brush head 92.

[0089] Reference Figure 24 In some embodiments, the first clamping arm 21 and the second clamping arm 22 are integrally formed with the baffle body 1. The integral forming method is conducive to improving production efficiency and eliminating the risk of loosening caused by the connection between the first clamping arm 21 or the second clamping arm 22 and the baffle body 1.

[0090] Reference Figure 3 , Figure 12 , Figure 13 and Figure 14 In some embodiments, the brush baffle further includes a connecting component 4, which is mounted on the baffle body 1 and is connected to the first connecting end 211 and the second connecting end 221 respectively. Specifically, the first clamping arm 21 and the second clamping arm 22 are connected to the baffle body 1 through the connecting component 4. This split connection method allows the first clamping arm 21, the second clamping arm 22 and the baffle body 1 to be manufactured independently during the production process, taking into account both the elasticity requirements of the first clamping arm 21 and the second clamping arm 22 and the rigidity requirements of the baffle body 1.

[0091] Reference Figure 3 and Figure 10In some embodiments, the baffle body 1 is provided with a mounting hole 101; the connecting component 4 includes a first connecting member 41 and a second connecting member 42. The first connecting member 41 includes a first connecting plate 410 and a first insert plate 411. The first connecting plate 410 is connected to the first connecting end 211, and the first insert plate 411 can be inserted into the mounting hole 101; the second connecting member 42 includes a second connecting plate 420 and a second insert plate 421. The second connecting plate 420 is connected to the second connecting end 221, and the second insert plate 421 can be inserted into the mounting hole 101. Specifically, the baffle body 1 is provided with a mounting boss 100, and a mounting hole 101 is provided at the mounting boss 100 and penetrates the mounting boss 100 along the thickness direction, so that the mounting hole 101 has a deeper hole depth, thereby improving the stability of the first insert plate 411 and the second insert plate 421 after insertion. Specifically, the outer contour formed by the first insert plate 411 and the second insert plate 421 is matched with the inner contour of the mounting hole 101, so that when the first insert plate 411 and the second insert plate 421 are inserted into the mounting hole 101, the first insert plate 411 and the second insert plate 421 are in contact, and the first insert plate 411 is in contact with the inner wall of the mounting hole 101, and the second insert plate 421 is in contact with the inner wall of the mounting hole 101, so that the first insert plate 411 and the second insert plate 421 are embedded and locked in the mounting hole 101; the first connecting plate 41 The first connecting end 211 of the first clamping arm 21 is integrally formed with the first clamping arm 21, and the second connecting plate 420 is integrally formed with the second connecting end 221 of the second clamping arm 22. It can be understood that the first connecting piece 41 is an extension structure of the first clamping arm 21, and the second connecting piece 42 is an extension structure of the second clamping arm 22. Specifically, the first clamping arm 21 and the first connecting piece 41, the second clamping arm 22 and the second connecting piece 42 can be integrally injection molded on the same set of molds, thereby reducing the number of parts produced. At the same time, the separate first clamping arm 21, the second clamping arm 22 and the baffle body 1 are conducive to the transportation of the brush baffle, reducing transportation costs and avoiding the situation where the width of the baffle body 1 is too large due to the connection of the first clamping arm 21 and the second clamping arm 22, which would increase transportation costs. To ensure better fit between the first insert plate 411 and the second insert plate 421, a fitting groove 4110 is provided on the first insert plate 411, and a fitting protrusion 4210 is provided on the second insert plate 421. In use, the first insert plate 411 and the second insert plate 421 are fitted together, and the fitting protrusion 4210 is engaged in the fitting groove 4110, so that the first insert plate 411 and the second insert plate 421 are kept in a mutually fitted position. At this time, the first clamping arm 21 and the second clamping arm 22 form a clamping cavity 200. Finally, the mutually fitted first insert plate 411 and the second insert plate 421 are simultaneously inserted into the mounting hole 101.

[0092] To further improve the stability of the first insert plate 411 and the second insert plate 421 on the baffle body 1, in some embodiments, at least one of the first insert plate 411 and the second insert plate 421 is provided with a buckle 423, and the inner wall of the mounting hole 101 is provided with a locking groove 1010 that can engage with the buckle 423. When both the first insert plate 411 and the second insert plate 421 are inserted into the mounting hole 101, the buckle 423 engages with the locking groove 1010, so that the first insert plate 411 and the second insert plate 421 cannot be disengaged from the mounting hole 1. The mounting hole 101 can be specifically provided with a buckle 423 at the end of the second insert plate 421 and a locking groove 1010 on the inner wall opposite to the mounting hole 101. After the first insert plate 411 and the second insert plate 421 are both inserted into the mounting hole 101, the buckle 423 is fastened to the locking groove 1010. Since the first insert plate 411 and the second insert plate 421 are tightly inserted into the mounting hole 101, the first insert plate 411 and the second insert plate 421 cannot be disengaged from the mounting hole 101, thus avoiding accidental disengagement during use.

[0093] Reference Figure 1 , Figure 3 , Figure 7 , Figure 9 In some embodiments, the baffle body 1 includes a fixed baffle 10 and a movable baffle 11. The fixed baffle 10 is used to connect the first clamping arm 21 and the second clamping arm 22. Specifically, a mounting hole 101 is formed on the fixed baffle 10, and the first clamping arm 21 and the second clamping arm 22 are fixed to the mounting hole 101 of the fixed baffle 10 by a connecting assembly 4. The movable baffle 11 includes a hinged end 110 and a free end 111. The hinged end 110 is hinged to the fixed baffle 10, and the free end 111 can rotate around the hinged end 110 to give the movable baffle 11 a first position (e.g., Figure 1 or Figure 7 The position shown) and the second position (as shown) Figure 9(As shown in the diagram), when the movable baffle 11 rotates to the first position, the movable baffle 11 and the fixed baffle 10 are approximately on the same plane to cover the bristles 92 of the brush 9. Specifically, the movable baffle 11 and the fixed baffle 10 are on the same plane and form an isolation surface 1100. The movable baffle 11 and the fixed baffle 10 do not form a through gap at the hinge to prevent paint from passing through the isolation surface 1100. That is, the movable baffle 11 and the fixed baffle 10 cover the bristles 92 of the brush 9, so that the isolation surface 1100 isolates the bristles 92 from the protective wall surface M2. When the movable baffle 11 rotates to the second position, the movable baffle 11 and the fixed baffle 10 form an angle β to expose the bristles 92 of the brush 9. The movable baffle 11 can be positioned in the second position by rotating it away from the bristles 92. Specifically, the angle β ranges from 60°. The angle β is 120 degrees, which limits the movable baffle 11 and the fixed baffle 10 to be in the same plane and form a 180-degree angle. When the free end 111 of the movable baffle 11 swings away from the end of the bristles 92, the movable baffle 11 and the fixed baffle 10 form an angle of less than 180 degrees. Continuing to rotate the movable baffle 11 can make the angle between the movable baffle 11 and the fixed baffle 10 smaller. When the movable baffle 11 and the fixed baffle 10 are perpendicular to each other, that is, the angle β is equal to 90 degrees, the movable baffle 11 is in the position furthest from the end of the bristles 92 in the width direction. The bristles 92 are fully exposed in the length direction, so that when the bristles 92 are dipped in paint, the movable baffle 11 will not interfere with the dipping operation of the bristles 92, and the paint is not easy to come into contact with the movable baffle 11, thus avoiding paint contamination on the movable baffle 11. To reduce the width of the brush baffle, allowing the brush bristles 92 to enter the smaller-diameter paint bucket T for paint picking, the movable baffle 11 can be further rotated so that the included angle β is approximately 60 degrees (e.g., ...). Figure 9 In the second position shown, the free end 111 is at its furthest point from the end of the bristles 92 along the length of the brush 9, and the distance between the free end 111 and the fixed baffle 10 is reduced, thus decreasing the overall width of the brush baffle. In short, when the movable baffle 11 is in the second position, the user can take the bristles 92 of the brush 9 and dip them into the paint bucket T. After dipping, the user can rotate the movable baffle 11 to the first position, achieving the effect of isolating the bristles 92 from the wall surface M2.

[0094] Reference Figure 3 and Figure 9In some embodiments, the movable baffle 11 further includes a limiting structure 112, which is disposed at the hinge end 110. The fixed baffle 10 is provided with a limiting groove 104. When the movable baffle 11 is in the first position, the limiting structure 112 abuts against the limiting groove 104 to restrict the movable baffle 11 from continuing to rotate in the direction of the brush bristles 92 of the brush 9. Specifically, the limiting structure 112 is a protrusion protruding from the hinge end 110, and the limiting structure 112 and the free end 111 are distributed on the axis of the hinge end 110. The two sides are arranged so that the rotation direction of the free end 111 is opposite to the rotation direction of the limiting structure 112, and the opening of the limiting groove 104 is set to face the bristles 92. When the movable baffle 11 switches from the second position to the first position, the free end 111 swings towards the bristles 92, while the limiting structure 112 swings away from the bristles 92 and finally abuts against the limiting groove 104, so that the movable baffle 11 is kept in the first position and the movable baffle 11 and its free end 111 are prevented from contacting the bristles 92.

[0095] Reference Figure 3 , Figure 7 , Figure 9 and Figure 10In some embodiments, the brush baffle further includes an adjusting rod 5. The fixed baffle 10 includes a first mounting platform 102 and a second mounting platform 103 spaced apart. The hinge end 110 is located between the first mounting platform 102 and the second mounting platform 103. One end of the adjusting rod 5 passes through the first mounting platform 102 and the hinge end 110 and is threadedly connected to the second mounting platform 103. The distance between the first mounting platform 102 and the second mounting platform 103 can be changed by rotating the adjusting rod 5. Specifically, a stepped countersunk hole is provided on the first mounting platform 102, and a threaded hole is provided on the second mounting platform 103. One end of the adjusting rod 5 is provided with an external thread that connects to the threaded hole, and the other end is provided with a nut. The middle area of ​​the adjusting thread is rotatably connected to the hinge end 110. The adjusting rod 5 is the hinge axis between the movable baffle 11 and the fixed baffle 10, and the hinge end 110 is the hinge shaft from the movable baffle 11. The structure with protruding edges has a hinge end 110 whose length is approximately the same as the distance between the first mounting platform 102 and the second mounting platform 103. The fixed baffle 10 is made of plastic, which allows it to deform under stress. The first mounting platform 102 and the second mounting platform 103, which protrude from the end of the fixed baffle 10, can also deform slightly under stress, allowing them to press the hinge end 110 together. Specifically, by rotating the adjusting rod 5, the first mounting platform 102 and the second mounting platform 103 are forced to move closer to each other, increasing the friction between the first mounting platform 102 and the hinge end 110, and between the second mounting platform 103 and the hinge end 110. This creates damping between the hinge end 110 and the fixed baffle 10, increasing the resistance when the movable baffle 11 rotates, allowing the movable baffle 11 to be rotated to a designated position and held there, thus enhancing the stability of the movable baffle 11 during use. It should also be noted that both the first mounting platform 102 and the second mounting platform 103 are cylindrical structures. The movable baffle 11 is also provided with flow-cutting surfaces 114 at both ends of the hinge end 110. The flow-cutting surfaces 114 are designed as arc surfaces corresponding to the outer contours of the first mounting platform 102 and the second mounting platform 103, and the flow-cutting surfaces 114 face away from the bristles 92. When the hinge end 110 is installed between the first mounting platform 102 and the second mounting platform 103 through the adjusting rod 5, the flow-cutting surfaces 114 are coaxial with the first mounting platform 102 and the second mounting platform 103, and the flow-cutting surfaces 114 are also coaxial with the first mounting platform 102 and the second mounting platform 103. The outer surface of 02 (second mounting platform 103) has a gap, and the intercepting surface 114 ensures that there is no gap penetrating from the thickness direction between the fixed baffle 10 and the movable baffle 11, so that the paint splashed from the brush bristles 92 cannot pass through the connection gap between the fixed baffle 10 and the movable baffle 11, thus preventing the protective wall surface M2 from being contaminated. The gap between the intercepting surface 114 and the outer surface of the first mounting platform 102 (second mounting platform 103) provides rotation space for the movable baffle 11 to rotate, so that the movable baffle 11 can switch between the first position and the second position.

[0096] Reference Figure 3 and Figure 4In some embodiments, the movable baffle 11 is provided with a guide channel 113, which is open to the free end 111. When the movable baffle 11 is in the first position, the guide channel 113 is close to the bristles 92 of the brush 9. The guide channel 113 can collect the paint splashed by the bristles 92 and does not contaminate the protective wall surface M2.

[0097] Reference Figure 1 , Figure 7 , Figure 10 and Figure 11 In some embodiments, the brush baffle also includes a support assembly 6, which includes a mounting base 60 and a support member 61. The mounting base 60 is fixed on the side of the baffle body 1 away from the brush 9, and the support member 61 is disposed on the mounting base 60. Specifically, the mounting base 60 is disposed on the fixed baffle 10. When the movable baffle 11 is in the first position, the support member 61 is the highest protruding structure on the fixed baffle 10. The support is achieved by contacting the protective wall surface M2 through the support member 61, so that the brush 9 keeps a distance from the protective wall surface M2 and avoids the brush bristles 92 getting too close to the protective wall surface M2 and causing contamination to the protective wall surface M2.

[0098] Reference Figure 10 and Figure 11 In some embodiments, the support member 61 is a roller or includes a roller. The roller is rotatably mounted on the mounting base 60, and the outer wall of the roller is provided with multiple friction-reducing grooves 6100. The rotatable roller is used to contact the protective wall surface M2. The rotation direction of the roller is the same as the direction in which the user picks up the brush 9 to paint. The multiple friction-reducing grooves 6100 can effectively reduce the friction between the roller and the protective wall surface M2 and improve the smoothness of the brush 9 when painting.

[0099] Reference Figure 15 In other embodiments, the support assembly 6' of the brush baffle includes a mounting base 60' and a support member 61'. The support member 61' includes an arc-shaped contact surface. Specifically, the arc-shaped contact surface can be a smooth surface with an outward convex curvature, such as a spherical surface or an arc surface. For example, a spherical support member 61' is integrally formed on the mounting base 60', and its surface forms an arc-shaped contact surface, so that the vertex of the arc-shaped contact surface is tangent to the protective wall surface M2, thereby reducing the contact area between the brush baffle and the protective wall surface M2 and effectively reducing the friction between the support member 61 and the protective wall surface M2.

[0100] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figures 16-24 In some embodiments, the brush baffle further includes a bracket 7, which includes a hinge portion 70 and an outer portion 73. The outer portion 73 is rotatable about the hinge portion 70, allowing the bracket 7 to rotate to a clamping position (e.g., Figure 7 , Figure 19 , Figure 23 (as shown in the image) Mounting location (e.g.) Figure 6 , Figure 17 , Figure 21 (as shown in the image) or support location (e.g.) Figure 8 , Figure 18 , Figure 22 (as shown in the image) at least one of the following positions; when the bracket 7 rotates to the clamping position, it clamps the first clamping arm 21 and the second clamping arm 22 so that the first clamping arm 21 and the second clamping arm 22 can clamp the brush 9 more firmly; when the bracket 7 is in the hanging position, the outer part 73 can hang the brush 9 upside down by hanging, for example, the outer part 73 hangs upside down on the side of the paint bucket so that the bristles 92 of the brush 9 face down, and the paint remaining on the bristles 92 drips into the paint bucket; when the bracket 7 rotates to the supporting position, it can support or lift the brush 9 along the length direction of the brush 9.

[0101] Specifically, depending on assembly requirements, the hinge portion 70 can be selected to hinge with different parts. For example, the hinge portion 70 can hinge with the baffle body 1; or the hinge portion 70 can hinge with the connecting assembly 4; or the hinge portion 70 can hinge with the first clamping arm 21 and / or the second clamping arm 22; the bracket 7 can be connected to the baffle body 1 (e.g., through its hinge portion 70) via the hinge portion 70. Figure 1 The fixed baffle 10 shown or the connecting component 4 (such as...) Figure 16 (as shown in the first connecting plate 410 and the second connecting plate 420) or as... Figure 20 The first clamping arm 21 and the second clamping arm 22 shown can rotate around the hinge 70 regardless of which part the hinge 70 is connected to, so that the bracket 7 can be rotated to the clamping position, the hooking position and the supporting position.

[0102] When the bracket 7 is in the clamping position, the external part 73 is connected to the end of the brush 9 away from the bristles 92, and the brush 9 is used for work; specifically, the external part 73 can adopt a hollow structure, so that the external part 73 fits on the brush head 91 of the brush 9, so that the external part 73 does not protrude from the brush baffle, and prevents the bracket 7 from interfering with the brush 9's painting operation during work.

[0103] When the bracket 7 is in the hanging position, the outer part 73 hangs the brush bristles 92 vertically downwards. Specifically, the outer part 73 can adopt a barbed structure. The bracket 7 swings to a position parallel to the fixed baffle 10, which is the hanging position. At this time, the brush baffle and brush 9 can be hung on the paint bucket T or other positions through the outer part 73, so that the brush bristles 92 of the brush 9 hang down. The residual paint on the brush bristles 92 can drip naturally into the paint bucket T, preventing paint waste and dripping to other places and causing pollution.

[0104] When the bracket 7 is in the supported position, the outer part 73 is close to the bristles 92 of the brush 9. The support is achieved through the outer part 73 and the end of the brush 9 away from the bristles 92, so that the bristles 92 are tilted upward. Specifically, when the bracket 7 is in the hanging position, the outer part 73 is in the position away from the end of the bristles 92. If the bracket 7 needs to be in the supported position, the bracket 7 is rotated so that the outer part 73 moves closer to the end of the bristles 92. When the outer part 73 is rotated to abut against the movable baffle 11, the bracket 7 is in the supported position. It can be understood that when the bracket 7 is rotated from the hanging position to the supported position, the outer part 73 changes from being away from the movable baffle 11 to being close to or in contact with the movable baffle 11. When the bracket 7 is in the supported position, the outer part 73 and the end of the handle 90 of the brush 9 away from the bristles 92 form a two-point support, so that the brush 9 can be placed on any flat surface without the bristles 92 coming into contact with the surface. This prevents the paint on the bristles 92 from being contaminated and also prevents the surface from being stained with paint.

[0105] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figures 16-24In some embodiments, the bracket 7 further includes a first connecting rod 71 and a second connecting rod 72. One end of the first connecting rod 71 is connected to the external connection portion 73, and the other end is connected to the hinge portion 70. One end of the second connecting rod 72 is connected to the external connection portion 73, and the other end is connected to the hinge portion 70. The first connecting rod 71 and the second connecting rod 72 are spaced apart to form a clamping space 720. When the bracket 7 is in the clamping position, a portion of the first clamping arm 21 and the second clamping arm 22 are clamped in the clamping space 720. The first connecting rod 71 is in contact with the first clamping arm 21, and the second connecting rod 72 is in contact with the second clamping arm 22. Specifically, the bracket 7 is formed by bending a thin metal rod, so that its two ends form a hollow external connection portion 73 and a hinge portion 70, and a first connecting rod 71 and a second connecting rod 72 connecting the external connection portion 73 and the hinge portion 70. A single thin metal rod is bent to form a rectangular ring, and the two ends of the single thin metal rod are made coaxial and close together to form a hinge 70. The other end is bent multiple times to form a hook-shaped outer part 73. A first connecting rod 71 and a second connecting rod 72 are formed between the two. The first connecting rod 71 and the second connecting rod 72 are spaced apart to form a clamping space 720. Since the bracket 7 itself is made of thin metal rod, the first connecting rod 71 and the second connecting rod 72 have elastic deformation capabilities, so that the clamping space 720 can strengthen the clamping effect on the first clamping arm 21 and the second clamping arm 22. That is, when the bracket 7 rotates to the clamping position, the first connecting rod 71 presses on the first clamping arm 21 and the second connecting rod 72 presses on the second clamping arm 22, so that the first clamping arm 21 and the second clamping arm 22 are pressed tightly towards the brush head 91. It should also be noted that, in order to improve the clamping effect of the hollowed-out outer part 73 on the brush 9, symmetrical clamping inner protrusions 730 can also be provided on the outer part 73. The distance between the two clamping inner protrusions 730 is less than the thickness of the brush 9, so that when the bracket 7 is in the clamping position, the two clamping inner protrusions 730 expand elastically and further clamp the brush 9, ensuring the stability of the bracket 7 in the clamping position.

[0106] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figures 16-24The hinge portion 70 includes a first hinge rod 701 and a second hinge rod 702. The first hinge rod 701 is connected to a first connecting rod 71, and the second hinge rod 702 is connected to a second connecting rod 72. The first hinge rod 701 and the second hinge rod 702 are coaxially spaced apart. Specifically, the bracket 7 is formed by repeatedly bending a single thin metal rod. By making the two ends of the single thin metal rod coaxial and close together, the first hinge rod 701 and the second hinge rod 702 are formed. When no external force is applied, the first hinge rod 701 and the second hinge rod 702 are brought together by their own elastic properties. By applying a force, the first hinge rod 701 and the second hinge rod 702 can elastically expand, so as to facilitate stable installation in the corresponding holes. (Refer to...) Figure 10 , Figure 16 , Figure 20 The brush baffle also includes a first hinge hole 81 and a second hinge hole 82. The first hinge hole 81 is rotatably connected to the first hinge rod 701, and the second hinge hole 82 is rotatably connected to the second hinge rod 702. The first hinge hole 81 and the second hinge hole 82 are coaxially arranged. The first hinge hole 81 and the second hinge hole 82 can be opened in different positions as needed.

[0107] like Figure 10 As shown, the first hinge hole 81 and the second hinge hole 82 are respectively provided on both sides of the baffle body 1. Specifically, the first hinge hole 81 and the second hinge hole 82 are opened on both sides of the mounting boss 100 of the fixed baffle 10. The first hinge hole 81 and the second hinge hole 82 are both connected to the mounting hole 101. Through holes can also be opened on the first insert plate 411 and the second insert plate 421. When the first insert plate 411 and the second insert plate 421 are both inserted into the mounting hole 101, the first hinge rod 701 is inserted into the first insert plate 411 after passing through the first hinge hole 81, and the second hinge rod 702 is inserted into the second insert plate 421 after passing through the second hinge hole 82, making the overall structure of the brush baffle more compact.

[0108] like Figure 16 As shown, the first hinge hole 81 and the second hinge hole 82 can also be provided on both sides of the connecting component 4. Specifically, the first hinge hole 81 is provided on the first connecting plate 410, and the second hinge hole 82 is provided on the second connecting plate 420.

[0109] like Figure 20 As shown, the first hinge hole 81 and the second hinge hole 82 may also be provided on the first clamping arm 21 and the second clamping arm 22, respectively.

[0110] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figures 16-24In some embodiments, the brush baffle further includes two first limiting slots 83, two second limiting slots 84, and two third limiting slots 85. When the bracket 7 is in the hanging position, the first connecting rod 71 and the second connecting rod 72 are respectively engaged in the two first limiting slots 83; when the bracket 7 is in the supporting position, the first connecting rod 71 and the second connecting rod 72 are respectively engaged in the two second limiting slots 84; when the bracket 7 is in the clamping position, the first connecting rod 71 and the second connecting rod 72 are respectively engaged in the two third limiting slots 85.

[0111] Specifically, two first limiting slots 83 are symmetrically arranged, two second limiting slots 84 are symmetrically arranged, and two third limiting slots 85 are symmetrically arranged to stably engage the first connecting rod 71 and the second connecting rod 72 on both sides of the bracket 7, thereby improving the stability of the bracket 7 in different positions. In addition, the positions and forms of the first limiting slots 83, the second limiting slots 84, and the third limiting slots 85 vary depending on the hinge of the hinge part 70 with different parts.

[0112] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, when the hinge part 70 is hinged to the baffle body 1, the first limiting groove 83 and the second limiting groove 84 are both provided on the outer wall of the mounting boss 100, and the first limiting groove 83 and the second limiting groove 84 are distributed on both sides of the first hinge hole 81 (second hinge hole 82). The first limiting groove 83 extends towards the handle 90 of the brush 9, and the second limiting groove 84 extends towards the bristles 92. Two third limiting grooves 85 are opened on the outside of the first clamping arm 21 and the second clamping arm 22, and the third limiting grooves 85 are inclined towards the brush head 91 of the brush 9. Through the engagement of the first connecting rod 71 (second connecting rod 72) with the first limiting groove 83, the first connecting rod 71 (second connecting rod 72) is kept in place. The brush 9 is held in a position approximately parallel to the handle 90, with the outer part 73 far from the bristles 92, so that when the outer part 73 is hung on an item such as a paint bucket T, the bristles 92 can hang vertically downwards. Conversely, rotating the bracket 7 causes the first connecting rod 71 (second connecting rod 72) to deform against the groove wall of the first limiting groove 83. When rotated to the position of the second limiting groove 84, the first connecting rod 71 (second connecting rod 72) elastically engages in the second limiting groove 84, keeping the bracket 7 in the support position. Similarly, rotating the bracket 7 causes the first connecting rod 71 (second connecting rod 72) to elastically deform, and when in the position of the third limiting groove 85, it elastically engages in the third limiting groove 85, keeping the bracket 7 in the clamping position.

[0113] like Figures 16-19As shown, when the hinge part 70 is hinged to the connecting assembly 4, two first limiting slots 83 are respectively provided on the first connecting plate 410 and the second connecting plate 420. Specifically, the first hinge hole 81 (second hinge hole 82) is provided at the end of the first connecting plate 410 (second connecting plate 420) near the bristles 92, and the first limiting slots 83 are distributed at the end of the first connecting plate 410 (second connecting plate 420) away from the bristles 92, and the first limiting slots 83 extend along the length direction of the brush 9. Two second limiting slots 84 are respectively provided on the first connecting plate 410 and the second connecting plate 420. The second limiting slots 84 are provided on the end wall of the first hinge hole 81 (second hinge hole 82). The second limiting slots 84 are distributed in the first hinge hole 81 (second hinge hole 82) compared to the first limiting slots 83. The hole 82) is located near the bristles 92. By rotating the bracket 7, the first connecting rod 71 (second connecting rod 72) can be elastically engaged into the first limiting slot 83, keeping the bracket 7 in the hanging position. Correspondingly, by rotating the bracket 7, the first connecting rod 71 (second connecting rod 72) can be elastically engaged into the second limiting slot 84, keeping the bracket 7 in the supporting position. It should be noted that when the hinge part 70 is hinged to the connecting assembly 4, the third limiting slot 85 may not be provided. The distance between the first connecting rod 71 and the second connecting rod 72 is less than the minimum distance between the first clamping arm 21 and the second clamping arm 22. The first connecting rod 71 and the second connecting rod 72 are clamped to the outside of the first clamping arm 21 and the second clamping arm 22 by their elastic properties, pressing the first clamping arm 21 and the second clamping arm 22 onto the brush head 91 of the brush 9.

[0114] like Figures 20-23As shown, when the hinge part 70 is hinged to the first clamping arm 21 and the second clamping arm 22, the first hinge hole 81 and the second hinge hole 82 are respectively provided on the first clamping arm 21 and the second clamping arm 22. Two first limiting slots 83, two second limiting slots 84 and two third limiting slots 85 are also respectively provided on the first clamping arm 21 and the second clamping arm 22. Among them, the length direction of the first limiting slot 83 is approximately parallel to the length direction of the brush 9, one end of which is connected to the end of the first hinge hole 81 (second hinge hole 82), and the other end extends toward the handle 90 of the brush 9. The length direction of the second limiting slot 84 is set at an angle to the length direction of the brush 9, and one end of which is connected to the first limiting slot 81 (second hinge hole 82). One end of the hinge hole 81 (second hinge hole 82) extends towards the fixed baffle 10. The length direction of the third limiting groove 85 is set at an angle to the length direction of the brush 9. One end of the third limiting groove 85 is connected to the end of the first hinge hole 81 (second hinge hole 82), and the other end extends away from the fixed baffle 10. By rotating the bracket 7, the first connecting rod 71 (second connecting rod 72) undergoes elastic deformation and passes through the groove wall of the first limiting groove 83 (second limiting groove 84 or third limiting groove 85) and is respectively inserted into the third limiting groove 85 (first limiting groove 83 or second limiting groove 84), so that the bracket 7 is kept in the clamping position, the hanging position or the supporting position.

[0115] It can be seen that by engaging the first link 71 (second link 72) with the first limiting slot 83, the second limiting slot 84 or the third limiting slot 85, the bracket 7 can be held in different positions, thereby improving the stability of the bracket 7 in different positions.

[0116] The following are further examples combining the above content:

[0117] Example 1:

[0118] The overall structure of the brush baffle is as follows: Figures 1-14As shown, the baffle body 1 includes a fixed baffle 10 and a movable baffle 11. The movable baffle 11 is hinged to the fixed baffle 10 through a hinge end 110. Its free end 111 can rotate around the hinge end 110 to make the movable baffle 11 be in a first position or a second position. When the movable baffle 11 is in the first position, the movable baffle 11 and the fixed baffle 10 together form an isolation surface 1100, so that when the brush bristles 92 are painting the wall surface M1, the wall surface M2 is protected from being contaminated by the paint splashed by the brush bristles 92. When the movable baffle 11 is in the second position, the tail of the brush bristles 92 is exposed. At this time, the brush bristles 92 can be immersed in the paint bucket T to pick up the paint. An adjusting rod 5 is set between the hinge end 110 and the fixed baffle 10 to change the tightness of the rotation of the movable baffle 11 and improve the stability of the movable baffle 11 when rotating. The brush baffle also includes a first clamping arm 21 and a second clamping arm 22. The first clamping arm 21 and the second clamping arm 22 are connected to the mounting holes 101 on the fixed baffle 10 via a connecting assembly 4. Specifically, a first connecting member 41 is integrally formed at the first connecting end 211 of the first clamping arm 21, and a second connecting member 42 is integrally formed at the second connecting end 221 of the second clamping arm 22. The brush baffle is connected by a first insert plate 411 on the first connecting member 41 and a second insert plate 421 on the second connecting member 42. Within the mounting hole 101, and constrained by the snap fastener 423 and the locking slot 1010, the first clamping arm 21 and the second clamping arm 22 cannot detach from the fixed baffle 10 after installation, ensuring stability during operation. The first clamping arm 21 and the second clamping arm 22 are spaced apart and form a clamping cavity 200 that extends through both ends. The open clamping cavity 200 allows the brush baffle to accommodate brushes 9 of different widths and sizes. Furthermore, since both the first clamping arm 21 and the second clamping arm 22 are... Made of an elastic material, and with the distance D1 between the first clamping end 210 and the second clamping end 220 being smaller than the distance D2 between the first connecting end 211 and the second connecting end 221, the first clamping arm 21 and the second clamping arm 22 can elastically expand under force to accommodate brushes 9 of different thicknesses. Specifically, by placing the brush head 91 of the brush 9 between the first clamping end 210 and the second clamping end 220, applying force can cause the first clamping end 210 and the second clamping end 220 to elastically expand, ultimately holding the brush... The baffle is fastened to the brush head 91 of the brush 9; the brush baffle also includes a support component 6, which includes a mounting base 60 and a support member 61. The mounting base 60 is integrally formed on the fixed baffle 10, and the support member 61 is specifically a roller. The roller is rotatably mounted on the mounting base 60. The roller can keep the brush 9 at a certain distance from the protective wall surface M2, and the friction-reducing groove 6100 on the roller can reduce the friction between the roller and the protective wall surface M2, thereby improving the smoothness of the brush 9 when painting.The brush baffle also includes a bracket 7, which includes a hinge 70, an outer part 73, a first connecting rod 71 and a second connecting rod 72 for connecting the hinge 70 and the outer part 73. The hinge 70 is specifically hinged to the fixed baffle 10, and a first limiting groove 83 and a second limiting groove 84 are provided on the outer wall of the mounting boss 100 of the fixed baffle 10, so that the bracket 7 is kept in the hanging position and the support position, so that the brush 9 with the brush baffle installed can be properly placed. A third limiting groove 85 can also be provided on the first clamping arm 21 and the second clamping arm 22, so that the bracket 7 is kept in the clamping position, so that the bracket 7 does not protrude outward and affect the normal operation of the brush 9, and can further enhance the clamping effect of the first clamping arm 21 and the second clamping arm 22 on the brush head 91.
