[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 5 This utility model discloses an aluminum alloy grandstand frame. A support frame 3 is provided at the top of the upright column 2. An inclined beam 4 is installed inside the support frame 3. The top surface of the inclined beam 4 is connected to the bottom of the grandstand panel 1, providing solid support. Connecting columns 5 are equidistantly located on the side of the inclined beam 4 away from the grandstand panel 1. These are key support points for installing guardrails 7. Guardrails 7 are installed on the sides of the connecting columns 5 via a limiting component 6. The limiting component 6 includes a pad, a limiting rod 601, and a nut 602. The pad is located on the side of the connecting column 5 and is fixedly connected to the limiting rod 601 on one side. The side of the limiting rod 601 is connected to the nut 602. The upright column 2 is connected via the connecting... The connecting ring 8 is connected to the connecting ring 8 of the adjacent column 2. The connecting ring 8 and the connecting ring 8 of the adjacent column 2 on the same horizontal plane are horizontally fixed with a first connecting rod 9, a second connecting rod, a fourth connecting rod, and a fifth connecting rod. Through this simple but effective fixing method of the locking pin, multiple connecting rod components such as the first connecting rod 9, the second connecting rod, the fourth connecting rod, and the fifth connecting rod are horizontally installed. These connecting rods are evenly distributed and work together to provide strong support for the lateral stability of the entire grandstand frame. The front side of the first connecting rod 9 is connected to the connecting diagonal rod 10 by screws. The other end of the connecting diagonal rod 10 is fixed to the front side of the adjacent column 2 by screws.

[0024] In the first embodiment, two sets of connecting holes are provided on both sides of the guardrail 7, and two sets of limiting components 6 are provided. The two sets of limiting components 6 are located on the left and right sides of the connecting post 5. The limiting rod 601 passes through the connecting hole and has threads on the side. The nut 602 is connected to the thread and has one side in close contact with the inner side of the guardrail 7. The first connecting rod 9, the connecting diagonal rod 10 and the adjacent post 2 form a triangular support structure.

[0025] Specifically, the limiting rod 601 passes through the corresponding connecting holes on both sides of the guardrail 7, ensuring the horizontal positioning accuracy between the guardrail 7 and the connecting post 5. The nut 602 is tightly engaged with the thread of the limiting rod 601. When the operator slowly tightens the nut 602 along the limiting rod 601, the squeezing and fixing effect is achieved, and the guardrail 7 is installed on the connecting post 5. It will not easily loosen or shift. The front side of the first connecting rod 9 is connected to the connecting diagonal rod 10 with screws. The other end of the connecting diagonal rod 10 is fixed to the front side of the adjacent post 2. They form a triangular support structure, which can effectively disperse external forces, ensure the stability of the grandstand frame, and prevent it from shaking or deforming.

[0026] In embodiment 2, the bottom of the column 2 is fixedly connected with a support foot, the support frame 3 is connected to the installation inclined beam 4 by bolts, and the right side of the grandstand 1 is provided with a T-shaped connector;

[0027] Specifically, the support feet have a large bottom area and anti-slip texture, which increases friction and distributes pressure when placed on the ground. They also allow the grandstand frame to stand firmly on soft ground, preventing swaying and sinking. The T-shaped connectors are used to connect the seats and other components.

[0028] Working principle:

[0029] First, the grandstand 1 is connected to the top surface of the mounting beam 4 via its bottom. The mounting beam 4 is installed inside the support frame 3, which provides support for it, thus stably bearing the weight of the grandstand 1 and the audience standing on it. Connecting columns 5 are equidistantly positioned on the side of the top surface of the mounting beam 4 away from the grandstand 1. A limiting assembly 6 is used to install the guardrail 7. In the limiting assembly 6, a pad is fixed to the side of the connecting column 5 and connected to a limiting rod 601. The limiting rod 601 passes through the connecting holes on both sides of the guardrail 7 and is tightened using nuts 602, ensuring tight contact between the nuts 602 and the inner surface of the guardrail 7, achieving a stable installation and fixation of the guardrail 7. To ensure the surrounding protection, the columns 2 are connected and fixed to each other by connecting rings 8. Multiple connecting rods are installed horizontally on the connecting rings 8 on the same horizontal plane with the help of locking pins. The first connecting rod 9 is connected to the connecting diagonal rod 10 by screws and fixed to the front side of the adjacent column 2 to form a triangular support structure, which can effectively disperse external forces. Combined with the support feet at the bottom of the column 2 to enhance the stability of the contact with the ground, the whole process ensures that the entire grandstand frame structure is stable and not prone to shaking or deformation. At the same time, the T-shaped connectors on the side of the grandstand panel 1 facilitate its splicing with other components to form a whole. At this point, the entire process is completed.
