[0020] 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.

[0021] 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.

[0022] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses an aluminum alloy grandstand seat, including a fixed base 1 and a support leg 2. The fixed base 1 plays an important role in the overall structure by providing basic support and connecting the grandstand. An installation plate 6 is provided on its front side. At the connection between the fixed base 1 and the installation plate 6, installation grooves 11 are precisely chiseled on the upper and lower sides. These installation grooves 11 are consistent with the fixing devices 21 on the support leg 2. The support leg 2, as a vertical support component of the overall structure of the seat 5, has fixing devices 21 accurately installed on its upper and lower sides corresponding to the installation grooves 11, which can form a tight and stable connection after being embedded in the installation grooves 11. An installation frame 3 is installed above the support leg 2. The mounting frame 42 is installed above the mounting frame 3 through A clamp 4 and B clamp 41. A clamp 4 and B clamp 41 are tightly connected to the mounting frame 3 by a precise screw fixing method, thus providing a solid and reliable installation foundation for the mounting frame 42. The seat 5 and backrest 51 are installed in the middle position of the two mounting frames 42.

[0023] In embodiment 1, a fixing hole is provided above the support leg 2. The fixing devices 21 on the upper and lower sides of the support leg 2 are installed in the mounting groove 11 and then fixed through the fixing hole. Three support legs 2 are installed in the mounting groove 11 through the fixing devices 21. A V-shaped groove is provided above the support leg 2. A mounting bracket 3 is installed in the V-shaped groove. A clamp plate 4 and a clamp plate 41 are installed on the mounting bracket 3 by screws. Eight sets of clamp plates 4 and clamp plates 41 are installed above the mounting bracket 3. A rotating shaft is installed on the inner side of the fixing bracket 42. The other side of the rotating shaft is connected to the seat 5. A connector 4201 is installed on the outer side of the fixing bracket 42. A backrest 51 is installed above the connector 4201.

[0024] Specifically, fixing holes are made above the support legs 2. After ensuring that the fixing devices 21 on both sides of the support legs 2 are accurately installed in the mounting slots 11, the fixing devices are used to fix them through the fixing holes. The three support legs 2 are stably installed by the fixing devices 21. The three support legs 2 are arranged in a specific spatial distribution to achieve the most balanced and efficient support effect for the entire seat 5 structure. The unique V-shaped groove structure above the support legs 2, with its V-shaped angle, allows the mounting bracket 3 to be accurately embedded in it, so that it will not shift or shake during use. The A clamp 4 and the B clamp 41 are connected by a matching plate. The screws are installed on the mounting bracket 3. Eight sets of A-plates 4 and B-plates 41 are neatly and orderly installed on the top of the mounting bracket 3 according to specific layout and spacing requirements. A rotating shaft is cleverly installed on the inner side of the fixing bracket 42, and its other side is firmly connected to the seat 5, so that the seat 5 can be freely adjusted around the rotating shaft within a certain angle range to meet the diverse needs of different users for sitting angle. A connector 4201 is precisely installed on the outer side of the fixing bracket 42, and its top is tightly connected to the backrest 51. While ensuring that the backrest 51 is firmly installed, it can also provide users with a comfortable and safe backrest 51.

[0025] In embodiment 2, a mounting hole 61 is provided in the middle of the fixed base 1 and the mounting plate 6. The mounting hole 61 passes through the fixed base 1 and the mounting plate 6, and the fixed base 1 and the mounting plate 6 are firmly installed above the grandstand through the mounting hole 61. The three support legs 2 are connected in the middle by a connecting rod 7.

[0026] Specifically, a mounting hole 61 is provided in the middle of the fixed base 1 and the mounting plate 6. The mounting hole 61 passes through the fixed base 1 and the mounting plate 6. Through the mounting hole 61, the fixed base 1 and the mounting plate 6 can be installed firmly and accurately above the grandstand. The middle of the support legs 2 is connected by a connecting rod 7. This design of connecting the three support legs 2 by the connecting rod 7 significantly enhances the integrity and stability of the entire seat 5 support structure. It can effectively prevent individual support legs 2 from tilting, deforming or being damaged due to uneven force, and further improves the safety and reliability of the aluminum alloy grandstand seat 5 in long-term use, providing users with a more solid and reliable support guarantee.

[0027] Working principle:

[0028] First, align the retainers 21 on both the upper and lower sides of the support leg 2 with the mounting grooves 11 at the connection between the fixed base 1 and the mounting plate 6, so that the retainers 21 are embedded in the mounting grooves 11. Then, through the fixing holes on the upper part of the support leg 2, use the fasteners to firmly connect the support leg 2 to the fixed base 1, completing the installation of the support leg 2. The three support legs 2 are arranged in a specific distribution and connected to each other by the connecting rod 7, which enhances the overall stability and prevents problems caused by uneven force on the support legs 2. Next, embed the mounting bracket 3 into the V-shaped groove on the upper part of the support leg 2 to make it installed securely. Next, the A-clamp 4 and B-clamp 41 are installed at specific positions above the mounting bracket 3 using screws. The fixing bracket 42 is then fixed to the mounting bracket 3 using the A-clamp 4 and B-clamp 41. Since the rotating shaft inside the fixing bracket 42 is connected to the seat 5, the user can push the seat 5 according to their own needs to rotate it around the rotating shaft and adjust it to a suitable angle to obtain a comfortable sitting posture. At the same time, the connector 4201 on the outside of the fixing bracket 42 is connected to the backrest 51, which provides stable back support for the user. At this point, the entire workflow is complete.
