Description

Technical Field

[0001] This utility model relates to the technical field of tools, and in particular to a tool brush head and a tool brush. Background Technology

[0002] As a commonly used tool, the scrubbing brush is widely used in fields such as architectural decoration and home cleaning.

[0003] The existing brushes are mainly divided into two types: one is a simple brush that can be used independently, and the other is a combination brush that can be connected to an operating lever.

[0004] Simple scrubbing brushes typically consist of a brush plate and a handle that are directly fixed together. While the structure is simple, it cannot be adapted to an operating lever, which means that workers need to climb or use ladders when working at heights. This results in low work efficiency and safety hazards.

[0005] The modular brush consists of a brush plate and a base plate. The base plate is used to connect to the operating lever. The brush plate is usually assembled by inserting the edge of the base plate into a pre-set slot on the base plate. However, this structure is prone to lateral slippage of the brush plate due to insufficient friction during the application of force, which affects the quality of the work. In addition, the brush plate needs to be completely manually pulled out and separated when it is replaced, which is cumbersome and easily damages the slot structure of the base plate.

[0006] In addition, the working angles of the two existing types of brushes are mostly fixed or only support angle adjustment within a limited range, making it difficult to adapt to the operational needs of different inclined surfaces and affecting construction quality and efficiency. Utility Model Content

[0007] The purpose of this utility model is to provide a tool brush head and a tool brush, which can ensure a reliable connection between the brush plate and the base plate of the tool brush head while enabling quick and convenient replacement of the brush plate, thus significantly improving work efficiency.

[0008] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: In a first aspect, this utility model embodiment provides a tool brush head, comprising: The base plate extends horizontally and has inclined side edges. A brush plate is located at the bottom of the base plate, with its surface extending horizontally and its edge having an upwardly folded brush plate flange. The brush plate flange overlaps the side of the base plate in the horizontal direction, with one of the overlapping surfaces having an arc-shaped protrusion and the other having a positioning groove. In the locked state, the arc-shaped protrusion is embedded in the positioning groove. The pusher includes a pusher body disposed between the brush plate and the base plate and a push rod connected to the pusher body; the push rod passes through a mounting hole on the base plate; The control component includes a push rod control part, which is connected to the push rod for driving the push rod to slide along the mounting hole, thereby causing the push frame body to push the brush plate downward and separate it from the base plate; A handle connector, located on the base plate or the control assembly, is used to connect to the tool handle.

[0009] In an optional embodiment, the brush plate flange is located on the outer side of the base plate side, the positioning groove is provided on the outer side wall of the base plate side, the arc-shaped protrusion is provided on the brush plate flange, and the brush plate flange is a curved plate structure with uniform wall thickness everywhere.

[0010] In an optional embodiment, the push rod control component includes a sleeve structure, a pusher button, and a spring; The sleeve structure is connected to the base plate and extends upward toward the base plate. The inner cavity of the sleeve structure communicates with the mounting hole of the base plate. The push rod passes through the sleeve structure. The push frame button is connected to the upper end of the push rod. The spring is sleeved on the outside of the push rod, and its upper and lower ends respectively abut against the push frame button and the sleeve structure. The spring is configured to: provide an upward elastic force to the pusher button in the locked state so that the pusher body is positioned above the brush plate; and, in the unlocked state, be elastically deformed by being pressed down by the pusher button so that the pusher button drives the push rod to push the brush plate downward away from the base plate.

[0011] In an optional embodiment, the handle connector is installed on the sleeve structure, with one end fitted onto the outside of the sleeve structure and the radially opposite side walls respectively hinged to the outer side wall of the sleeve structure via hinges, and the other end provided with a rod connection part for connecting to the tool operating lever.

[0012] In an optional embodiment, the control component further includes a positioning lock button, one end of which is provided with a limiting locking part; The sleeve structure is circumferentially rotatably mounted on the base plate, and the lower outer wall of the sleeve structure is provided with a limiting locking part two; The positioning lock button is slidably disposed on the base plate so that the first limiting lock part engages with the second limiting lock part in a concave-convex manner or so that the first limiting lock part disengages from the second limiting lock part.

[0013] In an optional embodiment, the base plate is provided with a slide rail groove, and the positioning lock button is inserted into and slidably installed in the slide rail groove.

[0014] In an optional embodiment, the sliding path of the positioning lock button relative to the base plate extends radially along the mounting hole, and the limiting locking part is provided at one end of the positioning lock button facing the mounting hole.

[0015] In an optional embodiment, the base plate is provided with a surrounding plate around the mounting hole. The surrounding plate is provided with a side through hole. An elastic buckle is also provided at the end of the positioning lock button facing the mounting hole. The upper end of the elastic buckle is provided with a locking protrusion. In the locked state, the limiting locking part and the elastic buckle both pass through the side through hole and extend into the interior of the mounting hole. Furthermore, the locking protrusion is engaged with the circumferential inner surface of the surrounding plate.

[0016] In an optional embodiment, the pusher button is fitted onto the outside of the upper end of the push rod. One of the inner circumferential surface of the pusher button and the outer circumferential surface of the upper end of the push rod is provided with an anti-detachment protrusion, and the other is provided with a circumferential groove. The anti-detachment protrusion is embedded in the circumferential groove.

[0017] Secondly, this utility model provides a tool brush, which includes an operating lever and a tool brush head provided in any of the optional embodiments of the first aspect, wherein one end of the operating lever is connected to the handle connector.

[0018] The tool brush head and tool brush provided in this embodiment can achieve at least the following beneficial effects: (1) The connection is reliable and the unlocking is controllable by using the inner and outer overlapping and the flange guiding structure: the brush plate and the base plate are connected in the horizontal direction by the inner and outer overlapping of the brush plate flange and the side of the base plate. The locking structure is achieved by the matching structure of the arc protrusion embedded in the positioning groove. The brush plate flange is folded upward and forms an inner and outer overlapping structure with the side of the base plate in the horizontal direction. This not only enhances the structural strength of the connection area, but also plays a guiding role when replacing the brush plate: when the new brush plate is inserted into the bottom of the base plate, the inclined structure of the brush plate flange and the side of the base plate can naturally guide it into place, reducing the difficulty of installation; while the matching of the arc protrusion and the positioning groove automatically completes the final positioning, ensuring that the installation position is consistent each time, improving the consistency and reliability of assembly. This structure has good resistance to lateral vibration and resistance to falling off. During normal use, it can effectively prevent the brush plate from accidentally falling off and ensure the safety of operation. (2) Enables quick and convenient brush plate replacement, significantly improving efficiency: By setting up a pusher (including the pusher body and push rod) driven by a control component, the user only needs to operate the push rod control component to drive the push rod to slide downward along the mounting hole, thereby driving the pusher body to push the brush plate downward relative to the base plate. During the pushing process, the arc-shaped protrusion disengages from the positioning groove, causing the brush plate to detach from the base plate downward. The entire unlocking process does not require disassembling other parts or using auxiliary tools, making it simple to operate and responsive, greatly improving the efficiency of brush plate replacement, and is particularly suitable for cleaning tool scenarios that require frequent brush head replacement.

[0019] In summary, this utility model embodiment can ensure a reliable connection between the brush plate and the base plate of the tool brush head while enabling quick and convenient replacement of the brush plate, significantly improving work efficiency. Attached Figure Description

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] First aspect This embodiment provides a tool brush head, see reference. Figures 1 to 15 The tool brush head includes at least a base plate 1, a brush plate 2, a pusher 3, a control assembly 5, and a handle connector 4.

[0031] Both the surface of base plate 1 and the surface of brush plate 2 are defined to extend horizontally: The brush plate 2 is located at the bottom of the base plate 1. An inclined side edge 11 is provided at the edge of the base plate 1, and an upwardly folded brush plate flange 21 is provided at the edge of the brush plate 2. The brush plate flange 21 and the side edge 11 overlap horizontally, with one overlapping surface having an arc-shaped protrusion 211 and the other a positioning groove 111. In the locked state, the arc-shaped protrusion 211 is embedded in the positioning groove 111. The pusher 3 includes a pusher body 31 located between the brush plate 2 and the base plate 1, and a push rod 32 connected to the pusher body 31. The push rod 32 passes through a mounting hole 101 on the base plate 1. The control assembly 5 includes a push rod control component 51, which is kinetically connected to the push rod 32 and used to drive the push rod 32 to slide along the mounting hole 101, thereby causing the pusher body 31 to push the brush plate 2 downwards away from the base plate 1. A handle connector 4 is located on the base plate 1 or the control assembly 5 and is used to connect to a tool handle.

[0032] The tool brush head provided in this embodiment allows for quick replacement of the brush plate 2. Specifically, refer to... Figures 1 to 8 In the locked state, the brush plate flange 21 overlaps with the side edge 11 of the base plate in the horizontal direction, and the arc-shaped protrusion 211 is embedded in the positioning groove 111 to ensure that the brush plate flange 21 and the side edge 11 of the base plate are firmly engaged, and the brush plate 2 is locked to the base plate 1; when unlocking, refer to Figures 8 to 15 The push rod 32 is driven to slide downward along the mounting hole 101 by the push rod control component 51, thereby driving the push frame body 31 to push the brush plate 2 downward relative to the base plate 1. During the pushing process, the arc-shaped protrusion 211 disengages from the positioning groove 111, and the brush plate 2 disengages downward from the base plate 1. After the push rod control component 51 is reset, a new brush plate 2 can be reinstalled at the bottom of the base plate 1.

[0033] The tool brush head provided in this embodiment can achieve at least the following beneficial effects: (1) The connection is reliable and the unlocking is controllable by using the inner and outer overlapping and flange guiding structure: the brush plate 2 and the base plate 1 are connected in the horizontal direction by the brush plate flange 21 and the base plate side 11. The arc protrusion 211 is embedded in the positioning groove 111 to lock the connection. The brush plate flange 21 is folded upward and forms an inner and outer overlapping structure with the base plate side 11 in the horizontal direction. This not only enhances the structural strength of the connection area, but also plays a guiding role when replacing the brush plate 2. When the new brush plate 2 is inserted into the bottom of the base plate 1, the inclined structure of the brush plate flange 21 and the base plate side 11 can naturally guide it into place, reducing the difficulty of installation. The cooperation between the arc protrusion 211 and the positioning groove 111 automatically completes the final positioning, ensuring that the installation position is consistent each time, improving the consistency and reliability of assembly. This structure has good resistance to lateral vibration and anti-detachment ability. During normal use, it can effectively prevent the brush plate 2 from being accidentally loosened and ensure the safety of operation. (2) Enables quick and convenient brush plate replacement, significantly improving efficiency: By setting up a pusher 3 (including pusher body 31 and push rod 32) driven by control component 5, the user only needs to operate push rod control component 51 to drive push rod 32 to slide down along mounting hole 101, thereby driving pusher body 31 to push brush plate 2 down relative to base plate 1. During the pushing process, arc protrusion 211 disengages from positioning groove 111, causing brush plate 2 to disengage from base plate 1. The entire unlocking process does not require disassembling other parts or using auxiliary tools, making operation simple and responsive, greatly improving brush plate replacement efficiency, and is especially suitable for cleaning tool scenarios that require frequent brush head replacement; In summary, this embodiment can ensure a reliable connection between the brush plate of the tool brush head and the base plate while enabling quick and convenient replacement of the brush plate, significantly improving work efficiency.

[0034] In this embodiment, the brush plate flange 21 can be continuously arranged around the circumference of the brush plate 2, or at least two can be arranged at intervals along the circumference of the brush plate 2. The same number of bottom plate side edges 11 are designed at corresponding positions on the bottom plate 1. Preferably, as shown... Figures 1 to 15 As shown, brush plate flanges 21 are provided on at least one set of opposite sides of the brush plate 2, and bottom plate sides 11 are provided on at least one set of opposite sides of the bottom plate 1, thereby further enhancing the locking effect.

[0035] In an optional embodiment of this example, the brush plate flange 21 is located on the outer side of the base plate side 11, the positioning groove 111 is provided on the outer wall of the base plate side 11, the arc-shaped protrusion 211 is provided on the brush plate flange 21, and the brush plate flange 21 is a curved plate structure with uniform wall thickness everywhere.

[0036] In this embodiment, the brush plate flange 21 adopts a curved plate structure with uniform wall thickness throughout, and is located entirely outside the base plate side 11. This design not only improves the structural strength of the brush plate flange 21 itself, avoiding stress concentration or local deformation caused by uneven wall thickness, but also enhances the connection stability and torsional and bending resistance between the brush plate and the base plate, preventing loosening or detachment during use. At the same time, the location of the brush plate flange 21 outside the base plate side 11 helps to achieve a neat and beautiful external outline of the product, improving the overall industrial design quality. It can also protect the structure of the base plate side 11 through the brush plate flange 21, preventing damage to the base plate side 11 during construction and ensuring effective cooperation between the base plate side 11 and the brush plate flange 21 of the new brush plate 2 after the replacement of the new brush plate 2.

[0037] Continue to refer to Figures 1 to 15In an optional embodiment of this example, the push rod control component 51 includes a sleeve structure 511, a push rod button 512, and a spring 513. The sleeve structure 511 is connected to the base plate 1 and extends upward toward the base plate 1. The inner cavity of the sleeve structure 511 communicates with the mounting hole 101 of the base plate 1. The push rod 32 passes through the sleeve structure 511. The push rod button 512 is connected to the upper end of the push rod 32. The spring 513 is sleeved on the outside of the push rod 32, and its upper and lower ends respectively abut against the push rod button 512 and the sleeve structure 511. The spring 513 is configured to: provide an upward elastic force to the push rod button 512 in the locked state so that the push rod body 31 is positioned above the brush plate 2; and, in the unlocked state, be pressed down by the push rod button 512 to generate elastic deformation so that the push rod button 512 drives the push rod body 31 to push the brush plate 2 downward away from the base plate 1.

[0038] In this embodiment, the push rod control component 51 includes a sleeve structure 511, a push rod button 512, and a spring 513. These components are closely fitted together to form a compact whole. When it is necessary to remove the brush plate 2 from the base plate 1, the user can press down the push rod button 512 to compress the spring 513. After being compressed, the spring 513 undergoes elastic deformation. The push rod button 512 drives the push rod 32 to move downward, thereby driving the push rod body 31 to push the brush plate 2 downward to detach from the base plate 1. This design provides a simple and reliable unlocking mechanism, allowing the brush plate 2 to be easily separated from the base plate 1. The design of the spring 513 ensures that the brush plate 2 can be stably positioned on the base plate 1 when not in operation. At the same time, the elastic recovery characteristics of the spring 513 ensure that the push rod button 512, the push rod 32, and the push rod body 31 automatically reset after each operation, further simplifying the operation process when replacing the brush plate. To further improve the assembly reliability between the spring 513 and the push rod 32, the transverse cross section of the push rod 32 can be designed as a cross shape or other polygonal or irregular cross section. In addition, to prevent the push rod 32 from moving downward when the push button 512 drives the push rod 32 to move downward, thereby causing the push rod body 31 to push the brush plate 2 downward to separate from the base plate 1, a limiting beam can be provided on the side of the push rod body 31. The limiting beam can slide up and down along the limiting hole provided on the base plate 1, but the limiting hole restricts the limiting beam from rotating circumferentially along the push rod 32, thereby improving the stability and reliability of the entire action process of the push button 512 driving the push rod 32 to move downward, thereby causing the push rod body 31 to push the brush plate 2 downward to separate from the base plate 1.

[0039] In an optional embodiment of this example, the handle connector 4 is installed on the sleeve structure 511. One end of the handle connector 4 is fitted onto the outside of the sleeve structure 511, and the two radially opposite side walls are respectively hinged to the outer side walls of the sleeve structure 511 by pins, screws, rivets or other hinges 42. The other end of the handle connector 4 is provided with a rod connection part 41 for connecting with the tool operating lever. The rod connection part 41 may be a threaded or snap-fit ​​structure or other docking structure provided on the outer surface of the other end of the handle connector 4 or the inner surface of the end mating cavity.

[0040] In this embodiment, one end of the handle connector 4 is fitted onto the outside of the sleeve structure 511, and is hinged to the radially opposite side walls of the outer side wall of the sleeve structure 511 via the hinge 42, allowing the handle connector 4 to swing relative to the sleeve structure 511 in the up-down and back-forward directions. More specifically, in this structure, one end of the handle connector 4 is fitted onto the outside of the sleeve structure 511, and there is a gap between the fitted parts. This gap allows the handle connector 4 to tilt upward or return to its original position relative to the sleeve structure 511 like a "wrench handle," so that the tool brush head can adapt to different angles of the wall surface, providing greater operational flexibility and adaptability for the tool brush head.

[0041] Furthermore, the control component 5 also includes a positioning lock button 52, one end of which is provided with a limiting lock part 521; the sleeve structure 511 is circumferentially rotatably mounted on the base plate 1, and the lower outer wall of the sleeve structure 511 is provided with a limiting lock part 5111; one of the limiting lock part 521 and the limiting lock part 5111 is a protrusion and the other is a groove. The positioning lock button 52 is slidably disposed on the base plate 1 so that the limiting lock part 521 and the limiting lock part 5111 are in concave-convex cooperation or the limiting lock part 521 is disengaged from the limiting lock part 5111. When the positioning lock button 52 slides relative to the base plate 1 to the position where the first limiting lock part 521 and the second limiting lock part 5111 are in a concave-convex fit, the positioning lock button 52 locks the sleeve structure 511 to the base plate 1. At this time, the sleeve structure 511 cannot rotate circumferentially relative to the base plate 1, and the working angle is fixed. When the positioning lock button 52 slides relative to the base plate 1 to the position where the first limiting lock part 521 is disengaged from the second limiting lock part 5111, the positioning lock button 52 unlocks the sleeve structure 511 to the base plate 1. At this time, the sleeve structure 511 can rotate circumferentially relative to the base plate 1. The user can adjust the working angle of the sleeve structure 511 according to actual needs, and thus adjust the circumferential angle between the handle connector 4 and the base plate 1.

[0042] In this embodiment, the sleeve structure 511 is circumferentially rotatably mounted on the base plate 1. The user can flexibly adjust the angle of the sleeve structure 511 according to actual needs, so that the tool brush head can adapt to any working angle within 360° circumferentially, thereby further improving the angle applicability of the tool brush head and improving the ease of operation. In addition, by setting a positioning lock button 52, the sleeve structure 511 can be locked at a preset angle by using the concave-convex cooperation of the first limiting lock part 521 and the second limiting lock part 5111, preventing it from rotating when it is not needed, thus ensuring work quality and work efficiency.

[0043] In an optional embodiment of this example, the base plate 1 is provided with a slide rail groove 12, and the positioning lock button 52 is inserted into and slidably installed in the slide rail groove 12. In this embodiment, guided by the slide rail groove 12, the positioning lock button 52 can slide on a specific path to ensure precise control of its position. This helps to accurately engage or disengage the first limiting lock part 521 and the second limiting lock part 5111 when needed, thereby improving the accuracy and reliability of the operation.

[0044] In an optional embodiment of this example, the sliding path of the positioning lock button 52 relative to the base plate 1 extends radially along the mounting hole 101, and the limiting locking part 521 is provided at the end of the positioning lock button 52 facing the mounting hole 101. In this embodiment, the limiting locking part 521 is provided at the end of the positioning lock button 52 facing the mounting hole 101. By sliding radially, the positioning lock button 52 can accurately engage or disengage the limiting locking part 521 with the limiting locking part 5111 on the sleeve structure 511, ensuring the accuracy of locking and unlocking.

[0045] In an optional embodiment of this example, the base plate 1 is provided with a surrounding plate 13 surrounding the mounting hole 101. The surrounding plate 13 is provided with a side through hole 131. At the end of the positioning lock button 52 facing the mounting hole 101, an elastic buckle 522 is also provided. The upper end of the elastic buckle 522 is provided with a locking protrusion 5221. In the locked state, the limiting locking part 521 and the elastic buckle 522 both pass through the side through hole 131 and extend into the mounting hole 101. Furthermore, the locking protrusion 5221 is engaged with the circumferential inner surface of the surrounding plate 13. In this embodiment, thanks to the design of the elastic buckle 522 and the locking protrusion 5221, the user can complete the locking and unlocking operation simply by pushing the positioning lock button 52. Both the limiting locking part 521 and the elastic buckle 522 extend into the mounting hole 101 through the side through hole 131, and the locking protrusion 5221 is engaged with the circumferential inner surface of the enclosure 13. This design further ensures the precise control of the position of the positioning lock button 52 in the locked state, preventing accidental loosening or disengagement.

[0046] In an optional embodiment of this invention, the push button 512 is fitted onto the outer upper end of the push rod 32. One of the inner circumferential surface of the push button 512 and the outer circumferential surface of the upper end of the push rod 32 has an anti-detachment protrusion 5121, and the other has a circumferential groove 321. The anti-detachment protrusion 5121 is embedded inside the circumferential groove 321. This embodiment ensures a stable connection between the push button 512 and the push rod 32 through the design of the anti-detachment protrusion 5121 embedded inside the circumferential groove 321. This connection method prevents the push button 512 from accidentally loosening or falling off during use, enhancing the user experience.

[0047] Second aspect This embodiment provides a tool brush, which includes an operating lever and a tool brush head provided in any optional embodiment of the first aspect. The operating lever can be a rod of a fixed length or a telescopic rod. One end of the operating lever is connected to the handle connector 4. The specific connection method includes, but is not limited to, the one end of the operating lever being snapped, threaded, interference-fitted, or converted through an adapter to the handle connector 4. Alternatively, the handle connector 4 can be fixedly connected to the operating lever by a pin or screw.
