DETAILED DESCRIPTION
[0026] The present application is further described in detail below with reference to the accompanying drawings.
[0027] Example 1: Reference Figure 1 、 Figure 2 A split chair leg structure includes an intermediate body 100 and a single leg body 110. The intermediate body 100 is a metal part in the shape of a circular ring. A plurality of connecting rods 111 are arranged along the circumferential direction on the outer side of the intermediate body 100. The single leg body 110 is inserted into and fixed on the connecting rod 111.
[0028] Reference Figure 2 、 Figure 3 The monopod 110 is an injection-molded plastic part that can be modified to suit different chair legs. The monopod 110 has a receiving slot 112 along its length for inserting the connecting rod 111. In this embodiment, the connecting rod 111 is a rectangular structure with a hollow interior, and the corresponding receiving slot 112 is also of an adaptive shape. The monopod 110 has a limiting body that is inserted into the connecting rod 111 to secure the connecting rod 111 to the monopod 110. The limiting body is a limiting stud 113 and a screw block 114. The limiting stud 113 is threadedly connected to the connecting rod 111, and the screw block 114 is embedded in and presses against the monopod 110.
[0029] After insertion, to limit the insertion depth of the connecting rod 111 so that the limiting stud 113 can align with the connecting hole, in this embodiment, a positioning protrusion 115 is provided at the end of the connecting rod 111 near the intermediate body 100, and the single-leg body 110 has a positioning groove 116 for the positioning protrusion 115 to engage. When the positioning protrusion 115 is engaged and blocked by the inner wall of the positioning groove 116, a positioning effect is achieved.
[0030] It is worth noting that after the monopod 110 is fixed, there is a certain gap between the end of the monopod 110 and the edge of the intermediate body 100. In this way, when the chair legs are used, the gap between the two is a deformation space, which avoids the monopod 110 and the intermediate body 100 from being squeezed.
[0031] Example 2: The difference from Example 1 is that, referring to Figure 4During installation, the connecting rod 111 contains a filler body 120 with a threaded hole 121 for the retaining stud 113 to connect to. To facilitate insertion, the filler body 120 is positioned parallel to the bottom of the receiving groove 112 and is integrally injection-molded with the monopod 110. During installation, it is inserted into the connecting rod 111, which not only increases the strength of the connecting rod 111 but also increases the threaded connection length of the retaining stud 113, thereby enhancing the connection security.
[0032] Example 3: The difference from Example 1 is that, referring to Figure 5 、 Figure 6 、 Figure 7 The limiting body is a limiting pin 130, and the end of the limiting pin 130 has a horizontal bar 131. The single leg body 110 and the connecting rod 111 both have an avoidance groove 132 for the horizontal bar 131 to pass through. When inserted, the horizontal bar 131 will pass through the avoidance groove 132. In this embodiment, the limiting pin 130 and the connecting rod 111 are not threadedly connected, and the two can rotate. When the horizontal bar 131 rotates, it will be limited inside to fix the connecting rod 111 to the single leg body 110.
[0033] To limit the position of the horizontal bar 131 after rotation, a pressure block is provided inside the connecting rod 111 for pressing the horizontal bar 131 against the inner wall of the connecting rod 111. The pressure block comprises a base tube 133 fixed to the inner wall of the connecting rod 111, a sleeve 134 slidably connected to the base tube 133, and a pressure spring 135 disposed inside the base tube 133 and connected at one end to the inner wall of the sleeve 134. The pressure spring 135 is always kept compressed.
[0034] When the horizontal bar 131 is inserted, the pressure spring 135 will be further compressed. Then, after the horizontal bar 131 is rotated, the force applied to the limit pin 130 is released, and the pressure spring 135 will act on the sleeve 134. The top of the sleeve 134 will press the horizontal bar 131 against the inner wall of the connecting rod 111, thereby fixing the single-leg body 110 and the intermediate body 100.
[0035] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
