[0028] Please refer to Figure 1 The present embodiment provides a plug for a drying rod, comprising a plug body 1 with an expansion hole 11 and an expansion piece 2, the plug body 1 comprises a plurality of elastic portions 12 and a connecting portion 13, the elastic portions 12 are arranged around the expansion hole 11, the connecting portion 13 connects the same end of the plurality of elastic portions 12, the outer wall of the elastic portion 12 is provided with a clamping structure for clamping with the drying rod 3, the expansion piece 2 is inserted into the expansion hole 11 and presses the elastic portion 12, and the elastic portion 12 is subjected to pressure away from the axis direction of the expansion hole 11. Since the end of the elastic portion 12 away from the connecting portion 13 is independent of each other, it is easier to elastically deform, after the elastic portion 12 is inserted into the drying rod 3, the outer diameter surrounded by the elastic portion 12 is easily deformed and expanded radially under the extrusion action of the expansion piece 2, and is in interference fit with the inner wall of the drying rod 3, and then is clamped with the drying rod 3 through the clamping structure, which is simple in structure and convenient to operate.

[0029] Among them, please refer to Figure 2 The elastic portion 12 is a long strip structure, and its cross section is a fan-shaped cross section. The fan-shaped cross section not only has strong stability, but also can closely fit the inner wall of the drying rod 3 when cooperating with the drying rod 3 due to the arc-shaped outer wall, thereby improving the connection stability. In another embodiment, the cross section of the elastic portion 12 can also be triangular, square or other shapes. The number of the elastic portion 12 is 4, and the expansion hole 11 is symmetrically arranged and surrounds an oval outer contour through the connecting portion 13, which is convenient for cooperating with the oval drying rod 3. In another embodiment, the number of the elastic portion 12 can also be 3, 5 or other numbers. In another embodiment, the elastic portion 12 can also be enclosed into a circular, square or other shaped outer contour according to the shape of the drying rod 3.

[0030] The elastic part 12 has a hollow interior. This hollow structure allows the elastic part 12 to have better elastic deformation capability, enabling it to deform more easily and form a tighter contact with the inner wall of the drying rod 3, thus enhancing the stability of the connection. Furthermore, the hollow interior of the elastic part 12 significantly reduces the overall weight of the end cap, making the clothes rack lighter and easier for users to move and carry, while also reducing material usage and lowering manufacturing costs.

[0031] Please refer to the following: Figure 3 The elastic part 12 has a through-hole groove 121 on its outer wall. An elastic arm 14 extends from one end of the groove 121 near the connecting part 13, and the end of the elastic arm 14 is provided with the snap-fit ​​structure. As an extension of the groove 121, the snap-fit ​​structure at the end of the elastic arm 14 allows it to contact the inner wall of the drying rod 3 more directly and form a snap-fit. Because the elastic arm 14 has a certain degree of elasticity and deformation capability, it can automatically adjust the contact angle and force with the inner wall of the drying rod 3 during installation, thereby ensuring the tightness and stability of the snap-fit. Specifically, the groove 121 extends along the length of the elastic part 12, allowing the elastic arm 14 to bend and extend more smoothly during installation. In another embodiment, the groove 121 can also extend perpendicular to the length of the elastic part 12. In another embodiment, the groove 121 can also be replaced with a circular groove, a square groove, or a groove of other shapes.

[0032] The snap-fit ​​structure is a snap-fit ​​protrusion 15, and the end of the snap-fit ​​protrusion 15 away from the connecting part 13 is provided with a first guide slope 151. The first guide slope 151 can reduce the resistance during installation, improve the installation efficiency, and facilitate the insertion of the snap-fit ​​protrusion 15 into the drying rod 3, where it engages with the slot 31 on the drying rod 3, thus improving the ease of installation. In another embodiment, the snap-fit ​​structure can also be a bayonet, which engages with the snap-fit ​​part protruding from the inner wall of the drying rod 3.

[0033] Please refer to the following: Figure 4The plug body 1 further comprises a limiting boss 16, which is arranged at one end of the connecting part 13 away from the elastic part 12, and has an outer diameter greater than that of the connecting part 13. The limiting boss 16 plays a role of physical blocking, preventing the plug from being excessively inserted into the drying rod 3 during installation, facilitating the installation of the plug in the correct position, avoiding the failure of the clamping structure or the damage to the inner wall of the drying rod 3 due to excessive insertion. In addition, the limiting boss 16 can also prevent the clothes hanger from sliding off from both ends of the drying rod 3, improving the convenience of use. The outer contour of the limiting boss 16 is oval, and the edge is smooth without protruding sharp corners. During installation and use, the user is less likely to have a safety accident when contacting the limiting boss 16. In another embodiment, the outer contour of the limiting boss 16 can also be circular, rounded square or other shapes. The limiting boss 16 extends a limiting ring 161 around the connecting part 13. After the plug is inserted into the drying rod 3, the limiting ring 161 wraps one end of the drying rod 3, playing a role of limiting the horizontal movement of the plug in the drying rod 3, further improving the installation convenience. In addition, the limiting ring 161 can also enhance the sealing performance of the plug and the drying rod 3, preventing water vapor, dust and the like from entering the drying rod 3, further prolonging the service life of the drying rod 3.

[0034] The limiting boss 16 is provided with a plug-in seat 17 at one end away from the connecting part 13, and the expansion hole 11 penetrates the middle part of the plug-in seat 17. The plug-in seat 17 prolongs the insertion stroke of the expansion piece 2, increases the contact area between the plug body 1 and the expansion piece 2, so that the expansion piece 2 can be more firmly fixed in the plug body 1 after insertion, thereby enhancing the connection stability of the plug and the drying rod 3. The plug-in seat 17 comprises an inner ring part 171, an outer ring part 172 and a plurality of reinforcing ribs 173, the inner ring part 171 and the outer ring part 172 are connected through the reinforcing ribs 173, and the expansion hole 11 penetrates the inner ring part 171. The outer ring part 172 is connected with the inner ring part 171 through the reinforcing ribs 173, thereby enhancing the radial strength of the inner ring part 171 and improving its torsional resistance, so that the stability of the plug-in seat 17 is further improved. In addition, the reinforcing ribs 173 can reduce unnecessary material use while maintaining the strength of the plug-in seat 17, thereby reducing the cost and achieving lightweight.

[0035] The connecting part 13 includes an inner connecting part 131 and an outer connecting part 132. The inner connecting part 131 connects the inner side part of the elastic part 12 close to the expansion hole 11, ensures that the elastic part 12 can maintain a stable form and structure when being pressed by the expansion piece 2, realizes effective expansion fixation, and enhances the stability of the elastic part 12 when being stressed, preventing damage caused by stress concentration. The outer connecting part 132 connects the outer side part of the elastic part 12 away from the expansion hole 11, cooperates with the inner connecting part 131 to ensure the stability of the elastic part 12 when being expanded, and further improves the structural strength of the elastic part 12.

[0036] The outer connecting part 132 is provided with a processing fixed groove 133 extending in the direction away from the insertion direction of the expansion piece 2 and penetrating the limiting boss 16 to form a processing fixed hole 162. The processing fixed groove 133 and the processing fixed hole 162 are symmetrically arranged about the expansion hole 11. The clamping device of the processing mechanism can clamp the processing fixed groove 133 through the processing fixed hole 162 to process the blank of the plug body 1. In the embodiment, the number of the processing fixed groove 133 and the processing fixed hole 162 is two, which is set according to the number of clamping jaws of the clamping device of the processing mechanism. In another embodiment, the number of the processing fixed groove 133 and the processing fixed hole 162 can also be three, four or other numbers to further improve the clamping stability.

[0037] The elastic part 12, the connecting part 13, the limiting boss 16 and the plug-in seat 17 are integrally formed. Integrally forming eliminates the joints or connecting points between the elastic part 12, the connecting part 13, the limiting boss 16 and the plug-in seat 17, thereby enhancing the strength and stability of the overall structure. This enables the plug body 1 to more evenly distribute stress when being stressed, reducing the risk of damage caused by excessive local stress. In another embodiment, the elastic part 12, the connecting part 13, the limiting boss 16 and the plug-in seat 17 can also be connected together by assembly, including but not limited to threaded connection, clamping block connection and the like.

[0038] The outer wall of the elastic part 12 is provided with a guide rib 18 extending along the length direction of the elastic part 12, and the end of the guide rib 18 away from the connecting part 13 is provided with a second guide inclined surface 181. The guide rib 18 can guide the elastic part 12 to move smoothly along the direction of the guide rib 18, improving the assembly precision between the drying rod 3 and the plug body 1.

[0039] Please refer to Figure 5The inner diameter of the expansion hole 11 gradually decreases along the insertion direction of the expansion member 2. The expansion member 2 can be gradually and uniformly extruded during the insertion process, thereby improving the reliability and stability of the connection and reducing the failure and accidents caused by loose or invalid connection.

[0040] The plug body 1 is an elastic body made of plastic material. Since the inner diameter of the expansion hole 11 gradually decreases along the insertion direction of the expansion member 2, the expansion member 2 can be a common self-tapping screw, which has a cutting edge at the end and can cut threads by itself when screwed into the material. When the self-tapping screw is screwed into the expansion hole 11, the screw will advance along the direction of the gradually decreasing inner diameter due to the action of the cutting edge, and force the plastic material of the plug body 1 to elastically deform. As the self-tapping screw penetrates deeper, the plastic material will gradually fill the gaps between the threads of the screw, thereby forming a tight and fixed connection. In other embodiments, the expansion member 2 can also be an expansion screw, an expansion plug or other expansion member 2.

[0041] Please refer to Figure 6 The present application also provides a drying rod, which comprises the plug of the drying rod described above. The drying rod 3 is a tubular structure with through holes at both ends, and is provided with a clamping groove 31 at the end. The inner diameter of the drying rod 3 is greater than the outer diameter of the elastic part 12, the elastic part 12 is inserted into the drying rod 3, the expansion member 2 is inserted into the expansion hole 11 to make the elastic part 12 deform radially, and the clamping structure is clamped in the clamping groove 31. By using the plug of the present application, the assembly between the drying rod 3 and the plug is more convenient, fast and reliable, and the limiting boss 16 of the plug can well isolate the inner cylinder of the drying rod 3 from the outside, thereby prolonging the service life.

[0042] The process of installing the plug of the drying rod of the present application on the drying rod is as follows: the elastic part 12 is inserted into the drying rod 3 in advance until the limiting boss 16 abuts against the end face of the drying rod 3, at which time there is a gap between the elastic part 12 and the drying rod 3, and the clamping block 15 is arranged opposite to the clamping groove 31, then the self-tapping screw is inserted into the expansion hole 11 and screwed into the deep part, the elastic part 12 deforms outwardly under the gradual extrusion of the self-tapping screw, and finally fits with the inner wall of the drying rod 3 in interference, at which time the clamping block 15 is clamped in the clamping groove 31, so that the plug body 1 is clamped on the drying rod 3.

[0043] The present application also provides a clothes drying machine, which comprises the drying rod 3 mentioned above. Since the drying rod 3 is adopted, the overall installation steps of the clothes drying machine are more convenient and fast, the structure is more stable, and the service life is further prolonged.

[0044] The above specific examples further detail the purposes, technical solutions and beneficial effects of the present application, and it should be understood that the above only serves as specific embodiments of the present application and is not intended to limit the present application, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
