[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] This embodiment provides a technical solution:

[0031] Please see Figures 1-5 As shown, the portable, modular seat structure includes a seat plate 1, support parts 2 on the left and right sides of the seat plate 1, and a backrest assembly 3 at the top rear side of the seat plate 1. Slots 10 are provided at both ends of the seat plate 1, and two fixing slots 11 are provided at the top rear side of the seat plate 1. Two connecting bolts 12 are threaded to the rear end of the seat plate 1, with the ends of the connecting bolts 12 penetrating into the fixing slots 11. The support parts 2 include brackets 20, with the seat plate 1 resting above the two brackets 20. Insert plates 21 are fixed to the openings of the brackets 20, and the insert plates 21 engage with the corresponding slots 10. Two support legs 22 are fixed to the bottom of the brackets 20. The outer wall of the backrest assembly 2 has a groove 220, and the bottom of the groove 220 has a sliding hole 221. A slider 23 is slidably installed in the groove 220. A slider rod 25 is fixed at the bottom of the slider 23. The slider rod 25 is slidably connected to the sliding hole 221. A spring 26 is sleeved on the outside of the slider rod 25. A limit rod 24 is fixed at the top of the slider 23. The top of the limit rod 24 passes through the top of the support leg 22, the bracket 20 and the insert plate 21 in sequence. The backrest assembly 3 includes two symmetrical diagonal braces 30. A fixing block 31 that is inserted into the fixing groove 11 is fixed at the bottom of the diagonal brace 30. A connecting hole 310 is opened on the fixing block 31, and a connecting bolt 12 passes through the connecting hole 310.

[0032] In this embodiment, a handrail 4 is provided above the support 2, and two support rods 40 are bolted to the handrail 4 and the bracket 20. The handrail 4 and the bracket 20 are bolted to two support rods 40. This design enhances the stability and load-bearing capacity of the handrail 4, ensuring that the user can feel sufficient support when leaning on the handrail 4.

[0033] In this embodiment, the bracket 20 and the insert plate 21 are integrally formed, and the overall shape of the bracket 20 is L-shaped. The integrally formed structure improves the overall structural strength, thereby ensuring the reliable connection between the support part 2 and the seat plate 1.

[0034] In this embodiment, multiple crossbars 32 are bolted together between the two diagonal braces 30, and the diagonal braces 30 are inclined. The inclined design of the diagonal braces 30 increases the stability and load-bearing capacity of the structure, while the design of the crossbars 32 effectively enhances the lateral stability of the seat.

[0035] In this embodiment, the diagonal brace 30 and the fixing block 31 are integrally formed structures, and both the diagonal brace 30 and the fixing block 31 are hollow structures. The integrally formed diagonal brace 30 and the fixing block 31 have better connection strength, ensuring the service life and safety of the diagonal brace 30 and the fixing block 31.

[0036] In this embodiment, a dial hole 230 is provided on the outer wall of the slider 23, and the cross-sectional shape of the dial hole 230 is circular. The height of the slider 23 can be easily adjusted through the dial hole 230, which in turn facilitates the adjustment of the limiting rod 24.

[0037] In this embodiment, the slider 23 and the limiting rod 24 are integrally formed, and the size of the slider 23 is adapted to the size of the groove 220. This design reduces the overall weight while maintaining sufficient strength and rigidity, so that the seat is lightweight while also having good load-bearing capacity.

[0038] It should be added that, in this embodiment, a pull plate 27 is fixedly connected between two adjacent support legs 22 by bolts. The setting of the pull plate 27 increases the reliability and stability of the connection between the two support legs 22, thereby increasing the overall stability of the seat.

[0039] In practical use, the user first inserts their finger into the dial hole 230 and moves the slider 23 downward. The slider 23 drives the limiting rod 24 and the sliding rod 25 downward, and the spring 26 is compressed by the slider 23. Then, the user inserts the insert plate 21 into the slot 10. When the insert plate 21 is fully inserted into the slot 10, the user releases the slider 23. Under the elastic force of the spring 26, the limiting rod 24 passes through the bracket 20 and the insert plate 21, and the bracket 20 is fixed to the seat plate 1. Repeat the above steps and install the support part 2 on the other side. Next, the user inserts the fixing block 31 into the fixing groove 11 and tightens the connecting bolt 12. The end of the connecting bolt 12 passes through the connecting hole 310, and the fixing block 31 is fixed to the fixing groove 11. The backrest assembly 3 is then installed, and the seat is assembled.
