[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0026] This utility model embodiment provides a brush 100, such as Figure 1 As shown in Figure 2, the brush 100 includes a brush handle 110, a brush head 120, and two mounting structures 130. The brush head 120 is connected to one end of the brush handle 110, and the two mounting structures 130 are respectively mounted on opposite sides of the brush handle 110. The two mounting structures 130 are used to mount the two ends of the polishing strip 200. The first direction is perpendicular to the second direction.
[0027] By implementing this embodiment, when applying liquid, the brush handle 110 can be held and the brush head 120 can be used to apply the liquid. When polishing solids, the polishing strip 200 can be installed using the two mounting structures 130 on opposite sides of the brush handle 110, so that the polishing strip 200 surrounds the brush head 120. In this way, the brush handle 110 can be held and the brush head 120 can support the polishing strip 200 to polish solids. As can be seen, this embodiment expands the functionality of the brush 100, allowing the brush 100 to be used with the polishing strip 200 in more application scenarios, reducing the number of tools that construction workers need to purchase and carry.
[0028] It is worth mentioning that there are many implementations of the mounting structure 130, and this embodiment does not limit it. Two embodiments are listed below for illustration:
[0029] refer to Figure 1 In Embodiment 1, the mounting structure 130 is a clamping assembly, which is used to apply clamping force to the grinding strip.
[0030] In the second embodiment, the mounting structure 130 includes a barb. As long as a hole is provided on the grinding strip 200 to cooperate with the barb, the grinding strip 200 can be mounted using the barb.
[0031] In some embodiments, the clamping assembly includes a first magnetic member and a second magnetic member. The first magnetic member is fixed to the brush handle 110, and the second magnetic member can attract the first magnetic member. In use, the polishing strip 200 is first placed next to the first magnetic member, and then the second magnetic member is placed on the side of the polishing strip 200 away from the first magnetic member. In this way, the polishing strip 200 can be clamped by the force generated when the first magnetic member and the second magnetic member attract each other.
[0032] Specifically, the first magnetic component and the second magnetic component can be magnets that can attract each other, or one of them can be a magnet and the other can be iron or other metal that can be attracted by a magnet. As long as the first magnetic component can attract the second magnetic component and thus clamp the grinding strip, this embodiment does not limit it.
[0033] refer to Figure 1 , Figure 3 In some embodiments, the clamping assembly includes a clamping plate 131 and an elastic member 132. The clamping plate 131 includes a clamping portion 1311 and a connecting portion 1312. The clamping portion 1311 is located on the side of the clamping plate 131 closer to the brush head 120. The clamping portion 1311 and the brush handle 110 together define a clamping space. The connecting portion 1312 is located on the side of the clamping plate 131 away from the brush head 120. The connecting portion 1312 is rotatably connected to the clamping plate 131 to adjust the size of the clamping space. The elastic member 132 is connected to the clamping plate 131 and is used to deform and store energy when the clamping space expands.
[0034] In this embodiment, by applying force to the clamping plate 131 to rotate it, the clamping space between the clamping part 1311 and the brush handle 110 is expanded, and the polishing strip 200 can be placed into the clamping space. Since the elastic element 132 deforms and stores energy when the clamping space expands, the elastic element 132 will release energy and drive the clamping plate 131 to reset after the force is stopped. At this time, the clamping part 1311 will move towards the brush handle 110 until it cooperates with the brush handle 110 to clamp the polishing strip 200.
[0035] refer to Figure 3 In a specific embodiment, the elastic element 132 is a torsion spring, with its two ends abutting against the brush handle 110 and the clamping plate 131, respectively. With this configuration, when the brush handle 110 rotates relative to the clamping plate 131 to expand the clamping space, it can apply a force to the torsion spring, causing it to deform and store energy. Then, when the user stops applying force to the clamping plate 131, the torsion spring can release the energy and drive the clamping plate 131 to return to its original position.
[0036] In some embodiments, the elastic element 132 is a compression spring, which is disposed between the side of the clamping plate 131 away from the connecting portion 1312 and the brush handle 110.
[0037] Specifically, when the clamping plate 131 rotates relative to the brush handle 110, causing the clamping space between the clamping part 1311 and the brush handle 110 to expand, the side of the clamping plate 131 away from the connecting part 1312 will move towards the brush handle 110. Therefore, by placing the compression spring between the side of the clamping plate 131 away from the connecting part 1312 and the brush handle 110, the compression spring can be deformed and stored. This allows the compression spring to deform and store energy when the clamping space expands, so that when the user stops applying force to the clamping plate 131, the compression spring can release energy and drive the clamping plate 131 to reset.
[0038] refer to Figure 3 In some embodiments, the clamping assembly further includes a pivot 133, the connecting portion 1312 has two spaced-apart first connecting ears 13121 on the side facing the brush handle 110, the brush handle 110 has two spaced-apart second connecting ears 111 on the side facing the connecting portion 1312, the pivot 133 passes through the two first connecting ears 13121 and the two second connecting ears 111, and a torsion spring is sleeved on the pivot 133, the torsion spring being located between the two first connecting ears 13121 and the two second connecting ears 111.
[0039] Specifically, compared to an embodiment that only has one first connecting ear 13121 and one second connecting ear 111, with both ends of the rotating shaft 133 respectively mounted on the first connecting ear 13121 and the second connecting ear 111, this embodiment provides a more stable constraint on the rotating shaft 133. Therefore, even with long-term use, the clamping plate 131 remains stable and does not wobble when rotating relative to the brush handle 110. By mounting the torsion spring on the rotating shaft 133, a separate mounting structure 130 is not required to install the torsion spring, reducing structural complexity and facilitating the production of the brush 100.
[0040] refer to Figure 4 , Figure 5 In some embodiments, the clamping part 1311 is provided with a clamping flange 13111 on the side near the brush head 120, and the clamping flange 13111 extends toward the brush handle 110.
[0041] Specifically, the clamping protrusion 13111 can increase the clamping force applied to the polishing strip 200, thereby improving the connection stability between the polishing strip 200 and the brush 100, reducing the possibility of the polishing strip 200 being dislodged from the clamping space by external forces, resulting in an excellent user experience.
[0042] In a specific embodiment, the clamping convex edge 13111 is provided with a plurality of protruding teeth (not shown in the figure) on the side near the brush handle 110, and the plurality of protruding teeth are evenly distributed in the length direction of the clamping convex edge 13111.
[0043] Specifically, setting several protruding teeth can generate higher local pressure at the contact point with the grinding strip 200, which helps to clamp the grinding strip 200.
[0044] refer to Figure 4 , Figure 5 In a specific embodiment, the brush handle 110 is provided with clamping grooves 112 on both sides in the second direction. The clamping grooves 112 are used to cooperate with the protruding edge to clamp the polishing strip 200.
[0045] Specifically, the clamping groove 112 will cause a bend in the position where the polishing strip 200 is clamped, so that the polishing strip 200 is subjected to a direction away from the brush handle 110 ( Figure 1 When an external force is applied in the Y direction, the bent part can work together with the clamping protrusion 13111 to restrict the grinding strip from detaching from the clamping assembly, which helps to increase the clamping stability of the clamping protrusion 13111 on the grinding strip 200.
[0046] refer to Figure 4 , Figure 5 In a specific embodiment, when the elastic element 132 releases energy, the clamping protrusion 13111 is inclined toward the end of the brush handle 110 away from the brush head 120.
[0047] With this setting, the abrasive bar is applied in a direction away from the brush handle by 110 degrees. Figure 1 The external force (in the Y direction) and the clamping force applied by the clamping protrusion 13111 to the grinding strip 200 are set at an obtuse angle, which helps to increase the clamping stability of the clamping protrusion 13111 to the grinding strip 200.
[0048] This utility model embodiment also provides a multi-functional tool 1000, such as... Figure 1 , Figure 2 As shown, the multi-functional tool 1000 includes a brush 100 and a polishing strip 200. The brush 100 is the brush 100 shown in the above embodiment. The two ends of the polishing strip 200 are respectively mounted on the brush 100 through two mounting structures 130 of the brush 100. The polishing strip 200 is arranged to surround the brush head 120 of the brush 100 so that the brush head 120 can provide support for the polishing strip 200.
[0049] By implementing this embodiment, when applying liquid, the abrasive strip 200 can be left unattached; the brush handle 110 can be held and the brush head 120 used to apply the liquid. When abrading solids is required, the abrasive strip 200 can be installed using the two mounting structures 130 located on opposite sides of the brush handle 110, allowing the abrasive strip 200 to surround the brush head 120. This allows the brush handle 110 to be held, with the brush head 120 supporting the abrasive strip 200 for abrading solids. Therefore, the multi-functional tool 1000 of this embodiment is applicable to multiple usage scenarios, reducing the number of tools that construction workers need to purchase and carry.
[0050] In this specific embodiment, the sanding strip 200 is a sandpaper strip with various grit sizes, allowing the worker to select the appropriate strip based on the desired sanding precision. The sandpaper strip can be purchased and cut by the worker, or it can be provided by the brush manufacturer; this embodiment does not impose any limitations on this.
[0051] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
