Description

Technical Field

[0001] This utility model relates to the field of precision equipment cleaning and maintenance technology, specifically to a disposable cleaning grinding head. Background Technology

[0002] Currently, the cleaning and maintenance of switch machines and contact point assemblies requires eliminating dust, lint, and other contaminants, and is generally done manually using non-woven fabric for wiping. This method has inherent drawbacks: inconvenience and potential for omissions; uneven wiping force and angle, easily missing corners, and difficulty in guaranteeing cleaning effectiveness. Furthermore, while some simple fixed cleaning heads exist on the market, their structural design has significant shortcomings: non-woven fabric wiping heads are usually fixed using simple splicing or binding methods, which can easily slip or rotate relative to the head body during rotational wiping, severely affecting cleaning efficiency and effectiveness. Non-woven fabric wiping heads are typically made of sewn fabric, and the seams create raised ridges on the wiping surface. When these raised areas contact the contact surface, they not only fail to clean effectively but may also cause lint, stringing, or damage to the contact surface due to high-speed friction. Existing integrated grinding heads typically require the entire grinding head to be scrapped after the wiping head becomes dirty, as the wiping head cannot be replaced separately, resulting in material waste and increased operating costs. Therefore, there is an urgent need for a cleaning head that can be firmly fixed, has a flat wiping surface, and allows for quick replacement of the wiping head to reduce costs. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a disposable cleaning grinding head. Through a unique structural design, it solves the problems of unstable wiping head, raised wiping surface, and non-reusability.

[0004] To achieve the above and other objectives, this utility model provides a disposable cleaning grinding head, which includes:

[0005] A grinding head base, the grinding head base including a clamping shank and a tapered mounting portion connected together;

[0006] A wiping head, wherein the wiping head is sleeved around the conical mounting portion;

[0007] And a locking collar, which is sleeved on the outside of the wiping head and locks the wiping head onto the conical mounting part.

[0008] In one embodiment, the front surface of the clamping handle is provided with an anti-slip structure.

[0009] In one embodiment, the anti-slip structure is knurled, axially knurled, or threaded.

[0010] In one embodiment, the wiping head is a hollow frustum-shaped structure made of non-woven fabric, and the wiping head includes a proximal end and a distal end, both of which are open structures.

[0011] In one embodiment, a slit is formed on the cylindrical body of the wiping head that runs through its length and bends inward.

[0012] In one embodiment, a first groove is provided on the conical wall of the conical mounting portion near the proximal end, the first groove being used to accommodate the locking collar.

[0013] In one embodiment, a second groove extending through the length of the tapered mounting portion is provided on the tapered wall, and the slit of the wiping head is embedded in the second groove.

[0014] In one embodiment, the cross-section of the second groove is arc-shaped.

[0015] In one embodiment, the locking collar is made of an elastic material.

[0016] In one embodiment, the conical mounting portion and the wiping head are integrally injection molded.

[0017] The disposable cleaning grinding head used in this invention has the following beneficial effects:

[0018] (1) The surface of the conical mounting part is provided with an arc groove to accommodate the seam of the non-woven conical wiping head. After assembly, the seam will be embedded in the arc groove of the grinding head. This not only prevents the wiping surface from bulging due to the seam of the wiping head, but also prevents slippage between the non-woven wiping head and the grinding head from affecting the wiping effect.

[0019] (2) After the non-woven cloth wiping head is aligned with the arc groove of the grinding head and assembled, the locking ring is put on to prevent it from falling off. When the wiping head gets dirty or loses its wiping effect, you only need to remove the locking ring, replace the non-woven cloth wiping head, and then put the locking ring on again. There is no need to scrap the grinding head. Attached Figure Description

[0026] Please see Figures 1 to 5 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] like Figure 1 As shown, the disposable cleaning grinding head includes a grinding head base 1, which includes a clamping handle 12 and a conical mounting part 11 connected together. A wiping head 2 is provided around the conical mounting part 11, and a locking ring 3 is sleeved on the outside of the wiping head 2. The locking ring 3 locks the wiping head 2 onto the grinding head base 1.

[0028] Specifically, one end of the grinding head base 1 is a clamping handle 12 for connecting with the driving tool, and the other end is a tapered mounting part 11 for mounting the wiping head 2.

[0029] The front end surface of the clamping handle 12 is provided with an anti-slip structure 121. The anti-slip structure 121 can be knurled, axially knurled, or threaded. Its function is to increase friction and ensure that the output torque of the drive tool can be effectively and without loss transmitted to the grinding head base 1, preventing relative slippage between it and the chuck of the drive tool.

[0030] like Figure 2 As shown, the wiping head 2 can be a hollow frustum-shaped structure made of non-woven fabric through a sewing process. The wiping head 2 includes a proximal end 211 and a distal end 212. The proximal end 211 is the end with a larger diameter, and the distal end 212 is the end with a smaller diameter. Both the proximal end 211 and the distal end 212 are open structures. The shape of the wiping head 2 matches the conical mounting part 11 of the grinding head base 1.

[0031] like Figure 3As shown, a first groove 111 is formed on the conical wall of the conical mounting portion 11 along its circumferential direction near the proximal end 211. The first groove 111 is an annular groove, which can accommodate the locking collar 3.

[0032] The tapered mounting part 11 has a second groove 112 extending through the length direction on its tapered wall. The cross-section of the second groove 112 is preferably arc-shaped, i.e., an arc groove. Its depth and width can be designed to accommodate the opening 22 of the wiping head 2.

[0033] like Figure 5 As shown, the second groove 112 and the first groove 111 are connected.

[0034] The wiping head 2 includes a cylindrical body 21, on which a slit 22 is formed, running through the length direction and bending inward. The slit 22 is a longitudinal structure naturally formed by rolling and sewing the wiping head 2 from a fan-shaped sheet of non-woven fabric. In the assembled state, the slit 22 is aligned with and embedded in the second groove 112 on the grinding head base 1.

[0035] After assembly, the slot 22 will be inserted into the second groove 112 of the grinding head. This not only prevents the wiping surface from protruding due to the slot 22 in the wiping head 2, but also prevents slippage between the non-woven wiping head 2 and the grinding head from affecting the wiping effect.

[0036] By matching the second groove 112 and the seam opening 22, the protrusion of the seam can be hidden in the second groove 112, ensuring the absolute flatness of the wiping surface. The two side walls of the second groove 112 form an axial limit on the seam opening 22, which greatly enhances the anti-torsion ability.

[0037] The conical mounting part 11 and the wiping head 2 can be integrally injection molded.

[0038] The disposable cleaning head includes a locking collar 3, which can be made of an elastic material, such as silicone or rubber. The locking collar 3 is circular, and its inner diameter is slightly smaller than the outer diameter of the tapered mounting portion 1 on the proximal end 211 side after the wiping head 2 is assembled. It generates a clamping force by relying on its elastic deformation.

[0039] After the wiping head 2 is assembled with the slit 22 aligned with the semi-circular groove of the grinding head, the locking ring 3 is put on to prevent it from falling off. When the wiping head 2 becomes dirty or loses its wiping effect, the non-woven wiping head 2 can be quickly replaced without scrapping the grinding head.

[0040] like Figure 5 As shown, the second groove 112 intersects and passes through the first groove 111 on the extension path.

[0041] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
