[0028] refer to Figure 2 and Figure 3 The left and right sides of the limiting post 6 are fixedly connected to the splicing plate 3 and the limiting plate 7 respectively, and the limiting plate 7 is sleeved on the surface of the support rod 1.

[0029] The above scheme is adopted: by setting splicing plate 3 and splicing groove 4, the fixed plate 2 can be limited; by setting limiting post 6, the moving plate 802 can be limited; and by setting limiting plate 7, the control gear ring 901 can be supported.

[0030] refer to Figure 4 The fixing device 8 includes a screw 801, a movable plate 802 is sleeved on the surface of the screw 801, a transmission gear 803 is provided on the right side of the screw 801, and a fixing post 804 is provided on the left side of the movable plate 802.

[0031] The above solution is adopted: by setting the fixing device 8, the fixing plate 2 can be fixed, which makes it convenient for users to assemble the support rod 1.

[0032] refer to Figure 4 The control device 9 includes a control gear ring 901, a support column 902 is provided on the right side of the control gear ring 901, a control ring 903 is provided on the right side of the support column 902, and a control groove 904 is provided on the surface of the control ring 903.

[0033] By adopting the above solution, the control device 9 can control the fixing device 8, making it convenient for users to use the fixing device 8.

[0034] refer to Figure 2 , Figure 3 and Figure 4There are four screws 801, which are evenly distributed on the right side of the splicing plate 3 and rotatably connected to the splicing plate 3. The right side of the screws 801 passes through the limiting plate 7 and extends to the outside of the limiting plate 7 and is fixedly connected to the transmission gear 803. The moving plate 802 is threadedly connected to the screws 801 and is sleeved on the surface of the limiting post 6 and the support rod 1. The transmission gear 803 meshes with the control gear ring 901 on the side near the control gear ring 901. There are multiple fixed posts 804, which are evenly distributed on the surface of the moving plate 802 and are fixedly connected to the moving plate 802. The side of the fixed posts 804 away from the moving plate 802 passes through the splicing plate 3 and extends into the inner cavity of the splicing groove 4.

[0035] The above scheme is adopted as follows: by setting screw 801, the movable plate 802 can be moved; by setting movable plate 802, the fixed column 804 can be moved; by setting transmission gear 803, the screw 801 can be rotated; and by setting fixed column 804, the fixed plate 2 can be limited.

[0036] refer to Figure 2 , Figure 3 and Figure 4 Both the control gear ring 901 and the control ring 903 are sleeved on the surface of the support rod 1. The side of the control gear ring 901 closest to the limit plate 7 is rotatably connected to the limit plate 7. There are four support columns 902, which are evenly distributed on the surface of the control gear ring 901 and fixedly connected to the control gear ring 901. The side of the support column 902 away from the control gear ring 901 is fixedly connected to the control ring 903. There are multiple control grooves 904, which are evenly distributed on the curved surface of the control ring 903.

[0037] The above scheme is adopted as follows: by setting the control gear ring 901, the transmission gear 803 can be driven to rotate; by setting the support column 902, the control ring 903 can be supported; by setting the control ring 903, the support column 902 and the control gear ring 901 can be driven to rotate; by setting the control groove 904, the user can easily rotate the control ring 903.

[0038] When two support rods 1 need to be spliced ​​together, first place one support rod 1 at a suitable position on top of the other support rod 1, aligning the fixing plate 2 on one side with the splicing groove 4 of the splicing plate 3 on the other side. Then, place one support rod 1 downwards, allowing the fixing plate 2 to enter the inner cavity of the splicing groove 4. After the fixing plate 2 on one side enters the splicing groove 4 of the splicing plate 3 on the other side, rotate the control ring 903 on the surface of the other support rod 1. During the rotation of the control ring 903, it will drive the control gear ring 901 to rotate synchronously through the support column 902. As the control gear ring 901 rotates, it will drive... The transmission gear 803 rotates, which drives the screw 801 to rotate synchronously. During the rotation of the screw 801, the moving plate 802 moves on the surface of the support rod 1 and the limiting post 6 and moves closer to the splicing plate 3. At the same time as the moving plate 802 moves, it drives the fixing post 804 to move synchronously, so that the fixing post 804 enters the inner cavity of the fixing through hole 5 on the surface of the fixing plate 2 on one side. When the fixing post 804 enters the inner cavity of the fixing through hole 5, the rotation control ring 903 stops rotating, and the moving plate 802 and the fixing post 804 no longer move, thus completing the splicing.

[0039] In summary, this narrow foundation pit steel support assembly structure, through the coordinated use of support rod 1, fixing plate 2, splicing plate 3, splicing groove 4, fixing through hole 5, limiting column 6, limiting plate 7, fixing device 8, and control device 9, solves the problem that in existing foundation pit steel supports, the connection between two support rods is mostly fixed with bolts. During splicing, multiple bolts usually need to be tightened manually with tools, which is a cumbersome process and affects the efficiency of splicing.
