[0002] Chinese patent document CN218251644U discloses a technical solution entitled "A Processing Gun for a Weld Bead Cleaning Machine," which includes the following technical features: a gun body, a connecting tube, a brush head, a positioner, an insulating layer, a connecting section, a first external thread, a second internal thread, a connecting seat, brush bristles, a second external thread, a first internal thread, a groove, and a through hole. Because the brush head is a consumable item in actual use (the bristles on the brush head will shorten due to friction, corrosion, etc.), it is frequently disassembled and reassembled. However, in this technical solution, the brush head and the connecting tube are connected by a screw connection between the second external thread and the second internal thread. Therefore, disassembling the brush head requires a cumbersome rotation operation. Since the number of turns of the second external thread and the second internal thread is generally designed to be large in actual production, disassembly is time-consuming and laborious, causing significant inconvenience to related production processes. Therefore, it is essential to design an adapter for use in weld bead cleaning guns to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and shortcomings, and to provide a brush connector structure for use on a weld cleaning gun. This brush connector structure not only facilitates the quick connection of the brush bristles to the liquid supply line of the weld cleaning gun, but also meets the needs of quick disassembly and replacement. It makes the disassembly and assembly of the brush bristles very time-saving and labor-saving, which can effectively reduce the inconvenience to production.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A brush connector structure for use on a weld cleaning gun is characterized by including a sleeve tube and a connecting tube that can be disassembled and connected to the liquid supply line of the weld cleaning gun, wherein the sleeve tube and the connecting tube are connected and communicate with each other.

[0006] Preferably, the inner wall of the connecting pipe is provided with a locking ring groove.

[0007] Preferably, the brush connector structure applied to the weld cleaning gun further includes a liquid supply pipe body, wherein a positioning ring groove is formed on the outer circumferential surface of the liquid supply pipe body, and a positioning snap ring is embedded in the positioning ring groove; the connecting pipe is fitted onto the liquid supply pipe body, and the snap ring groove is snapped onto the positioning snap ring.

[0008] Preferably, an inner convex ring and an outer convex portion are arranged side by side along the axial direction on the inner wall of the connecting pipe, and the outer convex portion is closer to the pipe opening of the connecting pipe than the inner convex ring, and the locking ring groove is formed between the outer convex portion and the inner convex ring.

[0009] Preferably, the external protrusion includes at least two arc-shaped protrusions arranged around the inner hole of the connector, and each arc-shaped protrusion is arranged around the inner hole of the connector.

[0010] Preferably, the radial cross-section of the arc-shaped protrusion is trapezoidal.

[0011] Preferably, the inner hole of the inner convex ring is a non-circular hole.

[0012] Preferably, an abutting protrusion is provided on the inner circumferential surface of the inner protrusion ring.

[0013] Preferably, a clamping piece is formed by a recess in the tube wall at one end of the sleeve, and a liquid outlet hole is formed on the side wall of the clamping piece, which extends into the sleeve.

[0022] like Figure 1 and Figure 2 As shown, the present invention provides a brush connector structure for use on a weld cleaning gun, comprising a sleeve tube 1 and a connecting tube 2 that can be disassembled and connected to the liquid supply line of the weld cleaning gun. The sleeve tube 1 and the connecting tube 2 are connected and aligned.

[0023] In this brush connector structure, the sleeve tube 1 can be used to mount the brush bristles, and the connecting tube 2 can be detachably connected to the liquid supply line of the weld cleaning gun. This eliminates the need for cumbersome rotation operations for disassembly; a simple plug-and-play operation allows for quick installation and removal of the brush bristles. This not only facilitates rapid connection of the brush bristles to the liquid supply line of the weld cleaning gun but also meets the need for quick disassembly and replacement. It makes the installation and removal of the brush bristles very time-saving and labor-saving, effectively reducing inconvenience to production. Furthermore, the overall structure of this brush connector is relatively simple. Therefore, this brush connector structure has strong applicability.

[0024] The connecting pipe 2 can be detachably coupled to the liquid supply line of the weld cleaning gun. This can be either the liquid supply line being detachably coupled to the connecting pipe 2, or the connecting pipe 2 being detachably coupled to the liquid supply line. Both of these are within the scope of protection of this utility model.

[0025] like Figure 1 and Figure 2 As shown, the inner wall of the connecting pipe 2 is provided with a locking ring groove 21. This locking ring groove 21 can be used to achieve locking and positioning, which helps to achieve accurate and stable locking effect, thereby helping to further improve the reliability and applicability of the brush connector structure.

[0026] like Figures 3 to 5As shown, the brush connector structure applied to the weld cleaning gun also includes a liquid supply tube 3. A positioning ring groove 31 is formed on the outer circumferential surface of the liquid supply tube 3, and a positioning spring 32 is embedded in the positioning ring groove 31. When not under pressure, the outer wall of the positioning spring 32 protrudes outside the positioning ring groove 31; when under pressure, the positioning spring 32 retracts towards the bottom of the positioning ring groove 31. The connecting tube 2 is fitted onto the liquid supply tube 3, and the locking ring groove 21 is engaged with the positioning spring 32. This not only facilitates manufacturing but also facilitates assembly and disassembly, and ensures that the installation and positioning of the connecting tube 2 are very stable and reliable, thereby ensuring that the installation and positioning of the brush bristles are very stable and reliable, and thus giving the brush connector structure higher reliability and applicability.

[0027] like Figure 1 and Figure 2 As shown, an inner convex ring 22 and an outer convex portion 23 are arranged side-by-side along the axial direction on the inner wall of the connecting pipe 2, with the outer convex portion 23 positioned closer to the opening of the connecting pipe 2 than the inner convex ring 22. A locking groove 21 is formed between the outer convex portion 23 and the inner convex ring 22. This not only strengthens the connecting pipe 2 using the inner convex ring 22 and the outer convex portion 23, but also facilitates a more stable and reliable locking effect in the locking groove 21, thereby further improving the reliability and applicability of the brush connector structure. In actual assembly, the inner convex ring 22 can be used to position the brush bristles, which facilitates accurate installation of the bristles.

[0028] like Figure 2 As shown, the external protrusion 23 includes at least two arc-shaped protrusions 231 arranged around the inner hole of the connector 2, with each arc-shaped protrusion 231 surrounding the inner hole of the connector 2. This not only controls the amount of material used, but also provides a certain amount of retraction space for the positioning spring 32 by utilizing the gap between adjacent arc-shaped protrusions 231, thereby making disassembly and assembly smoother and ensuring very stable positioning, which in turn helps to further improve the reliability and applicability of the brush connector structure.

[0029] like Figure 2 As shown, the radial cross-section of the arc-shaped protrusion 231 is trapezoidal. This ensures that the mounting ring groove 21 has a good mounting effect, while allowing the two side walls of the arc-shaped protrusion 231 to have a guiding function, thereby enabling smoother assembly and disassembly, and further improving the applicability of the brush connector structure.

[0030] like Figure 1 and Figure 2 As shown, the inner hole of the inner convex ring 22 is a non-circular hole. This non-circular hole allows for fitting together, which prevents rotation and thus helps to further improve the reliability of the brush connector structure.

[0031] like Figures 3 to 5 As shown, in the actual manufacturing process, the liquid supply pipe body 3 can be made into an adapter so that the connecting pipe 2 can be connected to the liquid supply pipe 10 on the weld cleaning gun through this adapter. The adapter has a non-circular part that matches the non-circular hole, which can effectively meet the anti-rotation requirement and thus effectively meet the needs of actual use.

[0032] like Figure 2 As shown, an abutting protrusion 221 is provided on the inner circumferential surface of the inner protrusion ring 22. The abutting protrusion 221 can be used to abut against the liquid supply pipe body 3. This not only enhances the structural strength by using the abutting protrusion 221, but also facilitates accurate and stable assembly, thereby helping to further improve the reliability and applicability of the brush connector structure.

[0033] like Figure 2 As shown, the abutting protrusion 221 is located on the edge of one end of the inner protrusion 22 near the sleeve tube 1. The abutting protrusion 221 and the side wall of the inner protrusion 22 facing the sleeve tube 1 together form a flared opening 20 that gradually increases in size from the connecting tube 2 to the sleeve tube 1. This facilitates the diffusion of cleaning fluid onto the bristles and prevents backflow of cleaning fluid, thereby helping to further improve the reliability and applicability of the brush connector structure.

[0034] like Figure 3 , Figure 4 and Figure 6 As shown, a clamping piece 11 is recessed at one end of the sleeve tube 1. A liquid outlet hole 12, penetrating into the sleeve tube 1, is formed on the side wall of the clamping piece 11. Brush bristles 13 are embedded in the inner hole of the sleeve tube 1, and the ends of the brush bristles 13 are clamped by the clamping piece 11 and the inner wall of the sleeve tube 1. This not only facilitates stable positioning of the brush bristles 13 but also allows for sufficient and accurate liquid supply to the brush bristles 13 via the liquid outlet hole 12, thereby further improving the reliability and applicability of the brush connector structure.

[0035] like Figure 1 and Figure 2 As shown, the sleeve tube 1 and the connecting tube 2 are an integral structure. This not only facilitates manufacturing but also makes the brush connector structure more reliable, thus better meeting the needs of practical use.

[0036] The sleeve tube 1 and the connecting tube 2 are integral copper tube structures, which not only provide good electrical conductivity but also facilitate the compression processing of the sleeve tube 1 to form the clamping piece 11. Figure 1 and Figure 2 Before the sleeve tube 1 is compressed to form the clamping piece 11, an outlet hole 12 is first opened on the sleeve tube 1, and then the brush bristles 13 are placed behind the sleeve tube 1, so that the sleeve tube 1 forms the clamping piece 11. This can well meet the actual assembly requirements.

[0037] like Figure 1 and Figure 2 As shown, the opening of the connecting pipe 2 is a flared opening, which makes it easier to fit the connecting pipe 2 onto the liquid supply pipe body 3, thereby helping to further improve the convenience of installation and positioning.

[0038] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
