DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The following references are made Figures 1-4 The present application is described as follows:

[0027] Embodiment: The mounting firm and adjustable support provided by the present application has a structure design focusing on improving mounting stability and adaptability. The core components of the support include a circular fixed disc 1, a fixed rod 2, a threaded hole 3, a connecting rod 4, an operation hole 5, a fixed hole 7, and a bolt 8. Each component cooperates with each other to realize a specific function.

[0028] A mounting firm and adjustable support includes a circular fixed disc 1. The fixed disc 1 serves as the main connecting component of the support and the square tube 20. The center of the front side of the fixed disc 1 is coaxially connected with a fixed rod 2. The fixed rod 2 serves as a structure for bearing other components.

[0029] The fixed disc 1 is provided with three fixed holes 7 which are circumferentially spaced apart on the fixed disc 1. A bolt 8 is connected in the fixed hole 7. The square tube 20 is provided with a threaded hole corresponding to the fixed hole 7. The fixed disc 1 is fixedly connected with the square tube 20 through the bolt 8. However, only relying on the bolt 8 connection, when the fixed rod 2 bears a heavy object and is subjected to a radial force, the connection between the fixed disc 1 and the square tube 20 is prone to looseness and fracture due to excessive load.

[0030] To solve this problem, the support is provided with a special reinforcing structure. The fixed rod 2 is provided with a threaded hole 3 which extends rearwardly through the fixed disc 1. A connecting rod 4 is threadedly connected in the threaded hole 3. The rear end surface of the connecting rod 4 is provided with an operation hole 5.

[0031] When the square tube 20 is vertically arranged and a through hole is formed on the square tube 20, the connecting rod 4 can be inserted through the through hole and abut against the two side walls of the square tube 20. When the fixed rod 2 bears a radial force, the force not only acts on the bolt connection between the fixed disc 1 and the square tube 20, but also is transmitted to the connecting rod 4 through the threaded hole 3, and is shared by the abutting surface between the connecting rod 4 and the two side walls of the square tube 20, thereby significantly reducing the load of the connection part of the fixed disc 1 and enhancing the connection firmness.

[0032] In terms of adjusting the function, the connecting rod 4 is screwed by operating the hole 5 by utilizing the threaded connection characteristics of the connecting rod 4 and the fixed rod 2. Due to the transmission characteristics of the threaded connection, when the connecting rod 4 is screwed, it moves in the axial direction in the threaded hole 3, thereby realizing length adjustment. This design enables the bracket to flexibly adjust the length of the connecting rod 4 extending out of the fixed disc 1 according to the actual size of the square tube 20, and ensures that the connecting rod 4 can always effectively penetrate the square tube 20 and abut against the two side walls, thereby adapting to the installation requirements of square tubes 20 of different sizes and improving the versatility and application range of the bracket.

[0033] The connecting rod 4 penetrates the through hole on the square tube 20, thereby forming a connection to share the load of the connection part of the fixed disc 1.

[0039] On the basis of the original bracket penetrating the two side walls of the square tube 20 through the connecting rod 4 to share the load, a new structure of the nut 1 6 threaded with the connecting rod 4 is added to further optimize the connection stability of the bracket and the square tube 20. In this structure, the nut 1 6 is screwed on the connecting rod 4, the square tube 20 is clamped between the fixed disc 1 and the nut 1 6, and the fastening connection is realized by tightening the nut 1 6.

[0035] When the fixed rod 2 bears a load generated by a heavy object, the force is originally mainly borne by the bolt 8 connection between the fixed disc 1 and the square tube 20 and the abutment of the connecting rod 4 and the side walls of the square tube 20. After the nut 1 6 is added, the axial pressure generated by the tightening of the nut 1 6 directly acts on the square tube 20, so that the square tube 20 forms a stable stress state under the clamping of the fixed disc 1 and the nut 1 6. This clamping force can effectively limit the displacement tendency of the square tube 20 under stress, especially when subjected to a radial force or torque, the nut 1 6 and the fixed disc 1 jointly constitute a constraint for the square tube 20, reduce the local stress concentration of the connection part of the fixed disc 1 and the square tube 20, and further share the load of the connection part of the fixed disc 1.

[0036] In the design of the front end connection structure of the fixed rod 2 of the bracket, through the cooperative action of the connecting hole 9, the bolt 10, the nut 1 1, the positioning tube 1 2, the connecting groove 1 3, the positioning groove 1 4 and the accommodating groove 1 5, stable connection and accurate positioning of the round tube 21 are realized.

[0037] The front end of the fixed rod 2 is provided with a connecting hole 9 penetrating through the two sides in the radial direction, providing a mounting channel for the second bolt 10.

[0038] The second bolt 10 is connected with the second nut 11 in a threaded manner.

[0039] The inner diameter of the positioning tube 12 is greater than the diameter of the screw rod of the second bolt 10, so that the second bolt 10 can be freely sleeved on the second bolt 10, avoiding interference with the second bolt 10 and ensuring normal installation and fastening of the second bolt 10.

[0040] The fixed rod 2 is provided with a connecting groove 13 connected with the positioning tube 12, achieving installation and fixation of the positioning tube 12 on the fixed rod 2.

[0041] One end of the positioning tube 12 is provided with an arc-shaped positioning groove 14, and the radius of the positioning groove 14 is equal to the radius of the circular tube 21.

[0042] The fixed rod 2 is provided with a containing groove 15 containing the head part of the second bolt 10.

[0043] In the actual assembly process, the positioning tube 12 can be installed in the connecting groove 13 of the fixed rod 2 first, then the second bolt 10 is passed through the connecting hole 9 and the positioning tube 12, then the corresponding hole position of the circular tube 21 is aligned with the second bolt 10, the circular tube 21 is embedded in the positioning groove 14 of the positioning tube 12, and finally the second nut 11 is tightened to complete the connection of the circular tube 21 and the fixed rod 2.

[0044] The above only describes the preferred embodiments of the present application, and does not limit the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
