[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-3The elevator weighing frame longitudinal rod assembly shown includes a longitudinal rod body 100. Each end of the longitudinal rod body 100 is provided with an installation structure 200. The installation structure 200 includes an installation plate 201, an installation rod 202, and an installation groove 203. A limiting structure 300 is symmetrically arranged on the installation plate 201. A crossbar is provided between the installation plate 201 and the longitudinal rod body 100. The installation plate 201 is movably disposed at the end of the longitudinal rod body 100. The installation rod 202 is movably disposed between the installation plate 201 and the longitudinal rod body 100. Both ends of the installation rod 202 penetrate opposite end faces of the installation plate 201 and extend to the outside. The installation groove 203 is formed on the longitudinal rod body 100. The installation groove 203, through its connection with the installation rod 202, causes the installation plate 201 to be connected and limited to the longitudinal rod body 100. The installation plate 201 is U-shaped, and the installation rod 202 is T-shaped. The outer wall of the installation rod 202 is provided with external threads.

[0022] For details, please refer to the following: Figure 1 and Figure 2 In use, both ends of the longitudinal bar body 100 are connected to the crossbar via the mounting structure 200. The combination of the crossbar and the longitudinal bar body 100 forms an elevator load-bearing frame. The U-shaped design of the mounting plate 201 allows both ends of the mounting plate 201 to pass through the upper and lower end faces of the crossbar and extend to the upper and lower end faces of the longitudinal bar body 100. In actual use, the inner wall of the mounting plate 201 can be glued with elastic structures such as rubber pads or sponge pads to reduce frictional wear between the mounting plate 201 and the crossbar and longitudinal bar body 100, and to fill the gaps between the mounting plate 201 and the crossbar and longitudinal bar body 100, ensuring the stability of the mounting plate 201 in restricting the position of the crossbar and longitudinal bar body 100. After the mounting plate 201 is placed on the crossbar and longitudinal bar body 100, the mounting plate... Holes corresponding to the vertical positions of the mounting slots 203 are provided on mounting plate 201, allowing mounting rod 202 to pass through mounting plate 201 and longitudinal rod body 100 from top to bottom. Thus, with the connection between mounting rod 202 and mounting slots 203, the position of mounting plate 201 on longitudinal rod body 100 can be fixed, and the position between longitudinal rod body 100 and crossbar can also be fixed, providing effective support for the installation of longitudinal rod body 100 and crossbar. Therefore, only the mounting slots 203 at the corresponding positions need to be provided on longitudinal rod body 100 to complete the installation with crossbar in conjunction with mounting structure 200. While ensuring effective installation of longitudinal rod body 100, it is also convenient to disassemble and replace longitudinal rod body 100 individually, with low replacement cost. Moreover, mounting structure 200 can be reused, has a wide range of applications, and high use value.

[0023] The mounting structure 200 also includes a fastening ring 204 and a positioning element. The fastening ring 204 is sleeved on the mounting rod 202 and is used to limit the position of the mounting rod 202. The positioning element is disposed between the fastening ring 204 and the mounting rod 202.

[0024] For details, please refer to the following: Figure 2 and Figure 3 The inner wall of the fastening ring 204 is threaded, and the fastening ring 204 is threadedly connected to the mounting rod 202. After the mounting rod 202 is movably inserted into the mounting groove 203, the fastening ring 204 rotates along the bottom end of the mounting rod 202, thus allowing it to move along the mounting rod 202. The compression of the mounting ring 204 against the outer wall of the mounting plate 201 reinforces the position of the mounting rod 202, thereby preventing arbitrary vertical movement of the mounting rod 202. This strengthens the connection between the mounting rod 202 and the mounting groove 203, improving the connection between the mounting rod 202 and the mounting groove. Regarding the tightness of the connection 203, the mounting groove 203 on the longitudinal rod body 100 and the mounting rod 202 are directly interlocked, ensuring the efficiency of the longitudinal rod body 100 installation and reducing the cumbersome drilling process of the longitudinal rod body 100. The mounting rod 202 is also directly interlocked with the mounting plate 201, and the mounting rod 202 is only threaded to the fastening ring 204, ensuring the smoothness and efficiency of the mounting rod 202 passing through the mounting plate 201 and the longitudinal rod body 100, while also enhancing the stability and effectiveness of the longitudinal rod body 100 installation.

[0025] The positioning component includes a positioning rod 205 and a positioning groove 206. The positioning groove 206 is formed on the outer wall of the mounting rod 202. The positioning rod 205 is movably mounted on the fastening ring 204. The positioning rod 205 and the inner cavity of the positioning groove 206 are movably connected. The positioning component also includes a spring 207. The spring 207 is sleeved on the positioning rod 205. One end of the spring 207 is fixedly mounted to the inner wall of the fastening ring 204.

[0026] For details, please refer to the following: Figure 3The positioning rod 205 is movably mounted on the fastening ring 204 via a spring 207. The connection between the positioning rod 205 and the positioning groove 206 is used to reinforce the connection between the fastening ring 204 and the mounting rod 202, preventing stripping of the threads on the fastening ring 204 and the mounting rod 202 under prolonged heavy friction. This provides a safe support for the connection between the mounting rod 202 and the mounting groove 203, enhancing the safety of the connection. Simultaneously, the positioning rod 205 is mounted on the fastening ring 204 via the spring 207, facilitating operation. The end of the positioning rod 205 facing the positioning groove 206 is rounded. The positioning rod 205 is arc-shaped and can be directly separated from the positioning groove 206 under the action of external force. When the fastening ring 204 rotates along the mounting rod 202, the positioning rod 205 will also take advantage of the compression performance of the spring 207 to avoid affecting the rotation of the fastening ring 204. When the positioning rod 205 moves to the position of the positioning groove 206, the positioning rod 205 will automatically insert and connect with the positioning groove 206 using the elastic performance of the spring 207. Thus, while ensuring the effective connection between the fastening ring 204 and the mounting rod 202, the connection between the mounting rod 202 and the fastening ring 204 is further reinforced with safety.

[0027] In summary, the structural principle of the limiting structure 300 is the same as that of the positioning component. The setting of the limiting structure 300 facilitates the connection and positioning between the mounting plate 201 and the crossbar, ensures the stability of the mounting plate 201 on the crossbar, and thus enhances the firmness and effectiveness of the mounting plate 201 in installing the longitudinal bar body 100.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
