Technical Field
[0001] This utility model relates to the field of abrasive brush technology, specifically a horseshoe-shaped nano abrasive brush that can be used in a limited position. Background Technology
[0002] A nano-abrasive brush is a tool used for surface treatment, primarily for polishing and grinding various material surfaces to achieve a smooth, flat finish. The bristles of a nano-abrasive brush are typically extremely fine, reaching the nanometer level, allowing it to penetrate into tiny crevices and surface details for fine processing. A horseshoe-shaped nano-abrasive brush is a type of nano-abrasive brush with a horseshoe-shaped handle.
[0003] However, existing horseshoe-shaped nano-abrasive brushes lack a limiting structure during use. When the user applies excessive force, the workpiece may come into contact with the bottom of the horseshoe-shaped handle, causing equipment damage and hindering practical application. In addition, existing horseshoe-shaped nano-abrasive brushes lack a drainage structure, making it impossible to quickly discharge the grinding debris from the gaps between the nano-bristles, thus affecting the grinding effect.
[0004] Therefore, those skilled in the art provide a horseshoe-shaped nano-abrasive brush that can be used in a limited position to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a horseshoe-shaped nano-grinding brush with a limiting function, which solves the problems mentioned in the background art. These problems include: the lack of a limiting structure in existing horseshoe-shaped nano-grinding brushes, which can easily cause the workpiece to contact the bottom of the horseshoe-shaped handle when the user applies excessive force, resulting in equipment damage; and the lack of a drainage structure in existing horseshoe-shaped nano-grinding brushes, which cannot quickly discharge the grinding debris from the gaps between the nano-bristles, thus affecting the grinding effect.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a horseshoe-shaped nano-abrasive brush that can be used with a limiting position, including a horseshoe-shaped handle, a nano-bristle bundle detachably connected to the bottom of the horseshoe-shaped handle, a horseshoe-shaped groove provided at the bottom of the horseshoe-shaped handle and on the outside of the nano-bristle bundle, a limiting baffle detachably connected inside the horseshoe-shaped groove, and ball bearings rotatably connected at equal intervals at the bottom of the limiting baffle;
[0007] The horseshoe-shaped handle is equipped with a drainage component for expelling debris between the nanobristle bundles.
[0008] The above technical solution involves setting detachable limiting baffles around the bottom of the horseshoe-shaped handle. These baffles provide limiting protection during equipment use. When the user applies excessive force, the ball bearings at the bottom of the limiting baffles contact the workpiece, preventing direct contact between the horseshoe-shaped handle and the workpiece, thus protecting the handle. Furthermore, by incorporating a drainage component inside the horseshoe-shaped handle, debris between the nanobristles can be quickly discharged, ensuring grinding effectiveness and facilitating practical applications.
[0009] Preferably, both ends of the horseshoe-shaped handle are provided with first threaded holes, and both ends of the limiting baffle are provided with second threaded holes that cooperate with the first threaded holes. The first threaded holes are threaded with fastening screws, and one end of each fastening screw is threaded with the second threaded hole.
[0010] By using the above technical solution, the limiting baffle can be stably installed inside the horseshoe-shaped groove by using the connection between the fastening screw and the second threaded hole. At the same time, the limiting baffle can be easily replaced after the ball bearings at the bottom of the limiting baffle wear out.

[0012] The above technical solution utilizes the operation of a blower to direct air through the air inlet slot into the guide slot, thereby blowing the air through the chip removal hole onto the surface of the workpiece and discharging the grinding debris.
[0013] Preferably, the bottom of the horseshoe-shaped handle has a third threaded hole, and the interior of the third threaded hole is threaded with a connector, and the nano-bristle bundle is installed on the connector.
[0014] With the above technical solution, when it is necessary to disassemble and replace the nanobristle bundles, the connector can be removed from the inside of the third threaded hole, which is convenient and quick.
[0015] Preferably, the horseshoe-shaped handle has anti-slip textures evenly spaced on both sides.
[0016] The above technical solution utilizes anti-slip textures to increase the friction between the user's hand and the object, thereby improving the user experience.
[0017] Preferably, the limiting baffle has handle grooves on both sides, and the top of the inner wall of the handle groove is at the same level as the bottom of the horseshoe-shaped handle.
[0018] The above technical solution utilizes a handle groove, allowing the user's fingers to extend into the groove when holding the horseshoe-shaped handle, thereby increasing grip stability.
[0019] Preferably, a first filter screen is installed inside each of the blow holes, and a second filter screen is installed inside each of the air inlet slots.
[0020] Through the above technical solution, the first filter screen can prevent external dust and debris from entering the interior of the guide channel through the dust blowing hole, while the second filter screen can prevent dust from entering the interior of the guide channel through the air inlet channel.
[0021] Preferably, a power source is embedded at one end of the horseshoe-shaped handle, and a charging interface is provided on the outside of the power source. The power source is used to supply power to the fan. A switch is installed on the outside of the horseshoe-shaped handle, and the switch is electrically connected to the power source.
[0022] The above technical solution utilizes a switch-controlled power supply to power the blower fan, thereby controlling the blower fan's operation.
[0023] This invention provides a horseshoe-shaped nano-abrasive brush that can be used in a limited position, and has the following beneficial effects:
[0024] This horseshoe-shaped nano-abrasive brush with adjustable positioning baffles around the bottom of the horseshoe-shaped handle provides protection during use. When excessive force is applied, the ball bearings at the bottom of the baffles prevent direct contact between the handle and the workpiece, thus protecting the handle. Furthermore, a drainage component inside the handle quickly removes debris from between the nano-bristles, ensuring optimal grinding performance and facilitating practical applications.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0034] Reference Figures 1-7 This utility model provides a horseshoe-shaped nano-abrasive brush with a limited positioning function, including a horseshoe-shaped handle 1. Anti-slip textures 15 are equidistantly arranged on both sides of the horseshoe-shaped handle 1, increasing the friction for the user's grip and thus improving the performance. A nano-bristle bundle 2 is detachably connected to the bottom of the horseshoe-shaped handle 1, enabling abrasive operations. A third threaded hole 13 is provided at the bottom of the horseshoe-shaped handle 1, and a connector 14 is threaded into the interior of the third threaded hole 13. The nano-bristle bundle 2 is mounted on the connector 14. When it is necessary to disassemble and replace the nano-bristle bundle 2, the connector 14 can be easily and quickly removed from the interior of the third threaded hole 13.
[0035] A horseshoe-shaped groove 3 is provided at the bottom of the horseshoe-shaped handle 1 and on the outside of the nano-bristle bundle 2. A limiting baffle 4 is detachably connected inside the horseshoe-shaped groove 3. A ball bearing 5 is rotatably connected at an equal distance at the bottom of the limiting baffle 4. The limiting baffle 4 can limit and protect the equipment when it is in use. When the user applies excessive force, the ball bearing 5 at the bottom of the limiting baffle 4 can contact the workpiece, thus preventing the horseshoe-shaped handle 1 from directly contacting the workpiece, thereby achieving the purpose of protecting the horseshoe-shaped handle 1. Both ends of the horseshoe-shaped handle 1 have first threaded holes 6, and both ends of the limiting baffle 4 have second threaded holes 7 that mate with the first threaded holes 6. Each of the first threaded holes 6 has a fastening screw 8 threaded inside, with one end of each fastening screw 8 threaded into the second threaded hole 7. This connection between the fastening screw 8 and the second threaded hole 7 allows the limiting baffle 4 to be stably installed inside the horseshoe-shaped groove 3. Furthermore, it facilitates the replacement of the limiting baffle 4 after the ball bearing 5 at the bottom of the limiting baffle 4 wears out. Both sides of the limiting baffle 4 have handle grooves 16. These handle grooves 16 allow the user's fingers to fit inside the handle grooves 16 when holding the horseshoe-shaped handle 1, increasing grip stability. Figure 2 As shown, the top of the inner wall of the handle groove 16 is at the same level as the bottom of the horseshoe-shaped grip 1, which can increase the comfort of holding.
[0036] In one aspect of this embodiment, a discharge assembly is provided inside the horseshoe-shaped handle 1 to discharge debris between the nanobristle bundles 2. The discharge assembly includes a guide channel 9, a chip removal hole 10, an air inlet channel 11, and a blower 12. The guide channel 9 is located inside the horseshoe-shaped handle 1. The chip removal hole 10 is located at the bottom of the horseshoe-shaped handle 1 and communicates with the inside of the guide channel 9. A first filter screen 17 is installed inside each chip removal hole 10 to prevent external dust and debris from entering the inside of the guide channel 9 through the chip removal hole 10. The air inlet channel 11 is located at the top of the horseshoe-shaped handle 1, and the blower 12 is installed inside the air inlet channel 11. By operating the blower 12, air can be blown through the air inlet channel 11 into the inside of the guide channel 9, thereby blowing it through the chip removal hole 10 onto the surface of the workpiece, and thus discharging the grinding debris. Each air inlet slot 11 is equipped with a second filter screen 18, which can prevent dust from entering the interior of the guide slot 9 through the air inlet slot 11.
[0037] In one aspect of this embodiment, a power supply 19 is embedded at one end of a horseshoe-shaped handle 1, and a charging interface 20 is provided on the outside of the power supply 19, which can be used to charge the power supply 19. The power supply 19 is used to supply power to the blower fan 12, and a switch 21 is installed on the outside of the horseshoe-shaped handle 1, which is electrically connected to the power supply 19. In use, the switch 21 is used to control the power supply 19 to supply power to the blower fan 12, thereby controlling the operation of the blower fan 12.
[0038] Working principle:
[0039] When in use, the user holds the horseshoe-shaped handle 1 and inserts their fingers into the handle groove 16 to increase the stability of the grip. At the same time, the anti-slip texture 15 can further increase the stability of the grip.
[0040] Then, the workpiece is ground by the nano-bristle bundle 2 at the bottom of the horseshoe-shaped handle 1. During the grinding process, if the user applies excessive force, the nano-bristle bundle 2 will bend and the ball bearing 5 at the bottom of the limiting baffle 4 will contact the surface of the workpiece, thereby limiting and protecting the bottom of the horseshoe-shaped handle 1. This can prevent the horseshoe-shaped handle 1 from directly contacting the workpiece, thus achieving the purpose of protecting the horseshoe-shaped handle 1.
[0041] At the same time, the power supply 19 can be controlled by switch 21 to supply power to the blower 12, thereby controlling the operation of the blower 12. Through the operation of the blower 12, the air is blown through the air inlet groove 11 into the guide groove 9, so that it is blown through the chip blowing hole 10 onto the surface of the workpiece, thereby discharging the grinding debris and ensuring the grinding effect.
[0042] Furthermore, when the nanobrush bristle bundle 2 is damaged, the connector 14 can be removed from the inside of the third threaded hole 13 to replace the corresponding nanobrush bristle bundle 2 without replacing all the nanobrush bristle bundles 2, thus saving maintenance costs. At the same time, after the ball 5 at the bottom of the limit baffle 4 is worn, the limit baffle 4 can be easily replaced by removing the fastening screw 8.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
