[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 11The mounting structure 10 according to the embodiment of the present invention is described, comprising: a first bushing 11 and a second bushing 12. The mounting structure 10 has an axial direction A and a radial direction B.

[0036] Specifically, if Figure 1-Figure 11 As shown, one end of the first bushing 11 is open, and the second bushing 12 is fitted in the first bushing 11. The second bushing 12 has a first end 121 and a second end 122. The first end 121 is adjacent to one end of the first bushing 11, and the first end 121 is open. The second bushing 12 is configured such that when the second bushing 12 moves toward the other end of the first bushing 11, the first end 121 of the second bushing 12 is tightened radially inwardly along the first bushing 11.

[0037] Combination Figure 1-Figure 7 The first bushing 11 and the second bushing 12 extend along the axial direction A of the mounting structure 10. The first bushing 11 is open at one end along the axial direction A of the mounting structure 10. The first end 121 and the second end 122 of the second bushing 12 are respectively located at the two ends of the second bushing 12 along the axial direction A of the mounting structure 10. The second bushing 12 is inserted into the first bushing 11. The first end 121 of the second bushing 12 is arranged at the open end of the first bushing 11, and the second end 122 of the second bushing 12 is stopped against the inner wall of the other end of the first bushing 11 along the radial direction B of the mounting structure 10.

[0038] The first end 121 of the second bushing 12 can undergo a certain degree of elastic deformation along the radial direction B of the mounting structure 10. When the second bushing 12 moves in the first bushing 11 along the axial direction A of the mounting structure 10 toward the other end of the first bushing 11, the first end 121 is deformed along the radial direction B of the mounting structure 10 toward the central axis of the first bushing 11, forming an inwardly tightened state. The mounting structure 10 is suitable for cooperating with the handrail tube 20. In the prior art, the mounting structure 10 is fixed to the handrail tube 20 by rubber extrusion. When the handrail tube 20 shakes, the second bushing 12 is prone to friction with the handrail tube 20. Rubber is not wear-resistant and is easily damaged by extrusion, and its practicality is low. In this embodiment, the mounting structure 10 is fixed to the handrail tube 20 by tightening the second bushing 12 inward.

[0039] According to the mounting structure 10 of the embodiment of the utility model, the mounting structure 10 is suitable for cooperating with the handrail tube 20. The arrangement of the first bushing 11 and the second bushing 12 can enhance the structural strength of the mounting structure 10, reduce the assembly difficulty of the mounting structure 10, improve the firmness of the cooperation between the mounting structure 10 and the handrail tube 20, reduce the wear caused by friction between the mounting structure 10 and the handrail tube 20, enhance the practicability of the mounting structure 10, and extend the service life of the mounting structure 10.

[0040] According to some embodiments of the present invention, Figure 6 and Figure 7 As shown, at least one opening 123 is formed on the side wall of the second bushing 12, and the opening 123 extends along the axial direction of the first bushing 11, and the opening 123 penetrates the second bushing 12 along the thickness direction of the second bushing 12, and the opening 123 penetrates the end surface of the first end 121. The opening 123 penetrates the second bushing 12 along the radial direction B of the mounting structure 10, and the opening 123 extends along the axial direction A of the mounting structure 10. The opening 123 is formed by a part of the end surface of the first end 121 of the second bushing 12 being recessed along the axial direction A of the mounting structure 10 toward the second end 122. Therefore, the provision of the opening 123 facilitates the elastic deformation of the first end 121 of the second bushing 12. During the process of assembling the second bushing 12 into the first bushing 11, the first end 121 of the second bushing 12 can be tightened inwardly under the pressure of the inner circumferential wall of the first bushing 11, which facilitates the assembly of the first bushing 11 and the second bushing 12.

[0041] According to some embodiments of the present invention, Figure 6 and Figure 7 As shown, there are multiple openings 123, and the multiple openings 123 are arranged at intervals along the circumference of the second bushing 12. A first mounting portion 124 is formed between adjacent openings 123, and the multiple openings 123 are arranged at intervals along the circumference of the second bushing 12 to form multiple first mounting portions 124 arranged at intervals along the circumference of the second bushing 12. When the second bushing 12 moves in the first bushing 11 along the axial direction A of the mounting structure 10 toward the other end of the first bushing 11, the first mounting portion 124 is squeezed by the inner circumferential wall of the first bushing 11, so that the first mounting portion 124 is deformed to a certain extent along the radial direction B of the mounting structure 10 toward the direction close to the central axis of the second bushing 12. Therefore, the provision of multiple openings 123 facilitates the formation of multiple first mounting portions 124, leaving deformation space for the first mounting portions 124 when they are squeezed and tightened inward, and the multiple openings 123 are arranged at intervals along the circumference of the second bushing 12 so that the force on the multiple first mounting portions 124 can be more uniform, reducing the force on each first mounting portion 124, improving the fatigue resistance of the first mounting portions 124, and enhancing the durability of the second bushing 12.

[0042] According to some embodiments of the present invention, Figure 4 and Figure 5As shown, along the direction from one end of the first bushing 11 toward the other end of the first bushing 11, the inner wall surface of the first bushing 11 extends obliquely toward the direction close to the central axis of the first bushing 11. An accommodating cavity 111 is formed inside the first bushing 11, and the second bushing 12 is suitable for being assembled in the accommodating cavity 111. The accommodating cavity 111 extends along the axial direction A of the mounting structure 10, and the cross-sectional area of ​​the accommodating cavity 111 gradually decreases along the direction from one end of the first bushing 11 toward the other end of the first bushing 11. Along the axial direction A of the mounting structure 10, from the first end 121 of the second bushing 12 toward the second end 122, the outer peripheral wall surface of the second bushing 12 extends obliquely toward the direction close to the central axis of the second bushing 12, and the inner wall surface of the first bushing 11 is adapted to the outer peripheral wall surface of the second bushing 12. Therefore, the setting that the inner wall surface of the first bushing 11 extends obliquely toward the direction close to the central axis of the first bushing 11 facilitates the assembly of the second bushing 12. The inner wall surface of the first bushing 11 is adapted to the shape of the outer peripheral wall surface of the second bushing 12, which facilitates improving the assembly stability between the first bushing 11 and the second bushing 12 and improving the overall structural stability of the installation structure 10.

[0043] According to some embodiments of the utility model, the second bushing 12 is a polyvinyl chloride part. Polyvinyl chloride has excellent heat resistance, and the maximum operating temperature of polyvinyl chloride can reach 85°C. It has good resistance to thermal deformation. Polyvinyl chloride also has excellent oxidation resistance and good chemical stability. Polyvinyl chloride has good wear resistance and impact resistance, and the production cost of polyvinyl chloride is relatively low. Therefore, the second bushing 12 is a polyvinyl chloride part, which can effectively improve the structural stability of the second bushing 12, enhance the durability of the second bushing 12, improve the anti-deformation ability of the mounting structure 10, reduce the production cost of the mounting structure 10, extend the service life of the mounting structure 10, and improve the user experience.

[0044] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, it further includes: an end cover 13, which is arranged at one end of the first bushing 11, and the end cover 13 is configured to push the second bushing 12 to move toward the other end of the first bushing 11 when the end cover 13 moves toward the other end of the first bushing 11. The end cover 13 cooperates with one end of the first bushing 11, and the end of the end cover 13 adjacent to the first bushing 11 along the axial direction A of the mounting structure 10 is suitable for abutting against the end surface of the first end 121 of the second bushing 12. Thus, the end cover 13 can push the second bushing 12 to move toward the other end of the first bushing 11 so that the second bushing 12 is installed inside the first bushing 11. The end cover 13 also plays a role in limiting the second bushing 12 in the axial direction A of the mounting structure 10, fixes the second bushing 12 in the accommodating cavity 111 of the first bushing 11, prevents the second bushing 12 from falling off, and enhances the assembly stability of the internal structure of the mounting structure 10.

[0045] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the end cover 13 is threadedly connected to the first bushing 11. Threaded connection is a widely used detachable fixed connection with the advantages of simple structure, reliable connection, and convenient assembly and disassembly. The end cover 13 is formed with a thread at one end adjacent to the first bushing 11 along the radial direction B of the mounting structure 10, and the outer peripheral side wall of the first bushing 11 at one end along the radial direction B of the mounting structure 10 is formed with a thread suitable for matching with the end cover 13. In the process of tightening the end cover 13, the end cover 13 moves toward the direction of the other end close to the first bushing 11. Therefore, the threaded connection between the end cover 13 and the first bushing 11 can reduce the difficulty of assembly between the end cover 13 and the first bushing 11, simplify the connection method between the end cover 13 and the first bushing 11, and improve the stability and reliability of the matching between the end cover 13 and the first bushing 11, thereby enhancing the structural strength inside the mounting structure 10.

[0046] According to some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the end cover 13 includes: a first end cover segment 131 and a second end cover segment 132. The first end cover segment 131 is arranged on the outer peripheral side of the first bushing 11, and the first end cover segment 131 is connected to the first bushing 11. The second end cover segment 132 is arranged on the radial inner side of the first end cover segment 131, and one end of the second end cover segment 132 adjacent to the second bushing 12 abuts against the first end 121 of the second bushing 12. The first end cover segment 131 and the second end cover segment 132 extend along the circumference of the end cover 13. The first end cover segment 131 and the first bushing 11 can be threadedly connected. The first end cover segment 131 is formed with a thread on one side adjacent to the central axis of the mounting structure 10 along the radial direction B of the mounting structure 10, and a thread matching the first end cover segment 131 is formed on the outer peripheral side wall of one end of the first bushing 11 along the axial direction A of the mounting bracket. The second end cover segment 132 is connected to the first end cover segment 131, and the second end cover segment 132 is opposite to the first end cover segment 131 along the radial direction B of the mounting structure 10, and there is a certain distance between the first end cover segment 131 and the second end cover segment 132, which is suitable for accommodating one end of the first bushing 11 along the axial direction A of the mounting bracket.

[0047] Therefore, the first end cover section 131 is provided with a thread suitable for cooperating and connecting with the first bushing 11, and the second end cover section 132 is suitable for pushing the second bushing 12 to move along the axial direction A of the mounting structure 10 toward the other end of the first bushing 11, and fixing the second bushing 12 in the first bushing 11, so as to make the mounting structure 10 more secure, prevent the first bushing 11 and the second bushing 12 from shaking and loosening, and extend the service life of the mounting structure 10.

[0048] According to some embodiments of the present invention, Figure 8 and Fig. 9 As shown, a plurality of grooves 133 are formed on the outer circumferential surface of the first end cover segment 131, and the plurality of grooves 133 are arranged at intervals along the circumferential direction of the first bushing 11. The grooves 133 are formed by a portion of the outer circumferential surface of the first end cover segment 131 being recessed toward the inside of the end cover 13, and the grooves 133 can enhance the friction force on the surface of the first end cover segment 131, making the surface of the end cover 13 more non-slip and durable, thereby improving the practicality of the mounting structure 10, and at the same time making the appearance of the mounting structure 10 more beautiful, improving the user's perception.

[0050] The armrest 100 is suitable for being connected with the seat body 30, and the mounting structure 10 is connected between the seat body 30 and the armrest tube 20. The armrest tube 20 extends along the axial direction A of the mounting structure 10, and the armrest tube 20 is suitable for being fitted in the second bushing 12. The armrest tube 20 passes through the first end 121 opened by the second bushing 12 and is inserted in the second bushing 12, and the end cover 13 is passed through the armrest tube 20.
