[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, a dining chair includes a seat plate 1, a backrest 2 and a plurality of supporting legs. The backrest 2 is detachably arranged on one side of the top of the seat plate 1. A mounting cavity 3 is provided in the seat plate 1. Two opposing mounting blocks 4 are slidably provided in the mounting cavity 3. A socket 5 communicating with the mounting cavity 3 is provided at the bottom of the seat plate 1. A clamping block 6 slidingly extending into the mounting cavity 3 is inserted into the socket 5. The two mounting blocks 4 can slide relatively out of the mounting cavity 3 and be clamped in the clamping block 6. A mounting plate 7 is rotatably provided at the bottom of the clamping block 6, and a plurality of supporting legs are arranged at the bottom of the mounting plate 7.

[0017] During the use of the utility model, the cooperation between the installation block 4 and the clamping block 6 makes it easy to disassemble and install the support legs and the seat plate 1. The structure is simple and easy to operate. The backrest 2 and the seat plate 1 can also be disassembled, which is convenient for disassembly and transportation of the dining chair, avoiding the integrated dining chair from taking up more space during transportation and having to be transported multiple times, wasting time and transportation efficiency.

[0018] like Figure 1 As shown, a rotating rod 8 arranged in the installation cavity 3 is rotatably provided in the seat plate 1. The rod section of the rotating rod 8 located in the installation cavity 3 is provided with two sections of threaded structures with opposite threads. Two shaft sleeves 9 are correspondingly threadedly sleeved on the two sections of the rod sections with opposite threads. Each shaft sleeve 9 is fixed with a bent connecting piece 10. The two installation blocks 4 are fixedly connected to the two connecting pieces 10 one by one, and two limiting grooves 11 are provided at the top of the installation cavity 3. A limiting block 12 is fixed on each shaft sleeve 9. The two limiting blocks 12 are correspondingly slidably provided in the two limiting grooves 11. An annular ring groove 13 is provided on the installation plate 7, and two first bolts 14 are threadedly passed through the clamping block 6. The two first bolts 14 are correspondingly threadedly connected to the two installation blocks 4, and the ring groove 13 is conductively opposed to the two first bolts 14. As shown Figure 1 As shown, a bearing 15 is provided at the bottom of the clamping block 6, and a positioning rod 16 is fixed on the mounting plate 7 at the center of the annular groove 13. The positioning rod 16 is vertically inserted into the center hole of the bearing 15 and the two are fixedly connected. Figure 1 As shown, a slider 21 is fixed on each side of the top of the mounting plate 7, and a circle of slide grooves 22 are opened at the bottom of the seat plate 1. Both sliders 21 are slidably arranged in the slide grooves 22. When it is necessary to position and install the seat plate 1 and the support leg, the operator makes the clamping block 6 pass through the socket 5 and is arranged in the mounting cavity 3, so that the two sliders 21 are arranged in the slide grooves 22. Then, the rotating rod 8 is rotated to make the two sleeves 9 relatively close to each other, thereby driving the mounting block 4 to clamp with the clamping block 6 through the connecting rod. During this process, the limit block 12 is slidably arranged in the limit groove 11. Afterwards, the operator makes the first bolt 14 pass through the annular groove 13, and makes the first bolt 14 threaded through the clamping block 6 and threadedly connected with the mounting block 4. This design method facilitates the positioning and installation between the seat plate 1 and the support leg, and has a simple structure and is easy to operate. The bearing 15 and the positioning rod 16 facilitate the rotation of the seat plate 1 relative to the support leg, making it convenient for the user to adjust the angle of the seat plate 1. The slider 21 and the slide groove 22 also facilitate the smooth rotation of the seat plate 1 to prevent the user from tipping over.

[0019] like Figure 1As shown, the support leg includes a sleeve 17 and a penetration rod 18. The sleeve 17 is fixed to the bottom of the mounting plate 7 and has an opening at the bottom of the sleeve 17. The penetration rod 18 slides vertically through the bottom of the sleeve 17. Two rows of opposing penetration holes 19 are vertically distributed on the penetration rod 18. Two opposing second bolts 20 are threadedly connected to the sleeve 17. The two second bolts 20 are threaded into the penetration rod 18 and are respectively threadedly connected to any one of the two opposing penetration holes 19. When the height of the support leg needs to be adjusted, the penetration rod 18 can be slid vertically, and then the two second bolts 20 can be threaded through. The two second bolts 20 are respectively threaded through the two penetration holes 19 and are threadedly connected to the penetration rod 18. This design method facilitates adjustment of the support leg height and has a simple structure and is easy to operate.

[0020] like Figure 2 As shown, the back of the backrest 2 is provided with a placement slot 23, and a sealing plate 24 is clamped at the slot of the placement slot 23. A hinge is provided between the sealing plate 24 and the bottom of the placement slot 23. A first magnetic strip 25 is provided on the sealing plate 24. A second magnetic strip 26 is provided on the backrest 2 above the placement slot 23. The first magnetic strip 25 and the second magnetic strip 26 are magnetically attracted to each other. Figure 2 As shown, the backrest 2 is provided with a slot 27 located above the second magnetic strip 26. A block 28 is slidably inserted into the slot 27. A placement rod 29 is fixed to the block 28 and slides horizontally through the backrest 2. The placement rod 29 is provided with multiple rubber bumps 30. A first magnet 31 is fixed to the block 28. The first magnet 31 is opposite the placement rod 29. A second magnet 32 ​​is fixed to the slot 27, opposite the first magnet 31. The first magnet 31 and the second magnet 32 ​​are magnetically attracted to each other. When the user feels hot while dining and wants to take off clothes or place small items, they can open the sealing plate 24 to separate the first magnetic strip 25 from the second magnetic strip 26. At this time, the small items to be placed are placed in the placement slot 23. Then, the placement rod 29 is slid out to separate the first magnet 31 from the second magnet 32. At this time, the clothes are hung on the placement rod 29. This design has a simple structure and is easy to operate. It prevents clothes from hanging on the backrest 2 during dining and causing them to fall off. It can also store objects and has a good effect.

[0021] like Figure 1 As shown, a connecting plate 33 with an opening at the top is fixed to one side of the top of the seat plate 1. The bottom of the backrest 2 is inserted into the opening of the connecting plate 33. A plurality of third bolts 34 are threaded through the connecting plate 33 and are threadedly connected to the backrest 2. This design facilitates the positioning, installation, and removal of the backrest 2, and its simple structure makes it easy to operate.

[0022] Working principle:

[0023] When the backrest 2 needs to be installed, the bottom of the backrest 2 is placed in the connecting plate 33 and a plurality of third bolts 34 are screwed in.

[0024] When the height of the support leg needs to be adjusted, the through-rod 18 can be slid vertically, and then two second bolts 20 can be threaded through the two through-holes 19 respectively and threadedly connected to the through-rod 18.

[0025] To position and install the seat plate 1 and support leg, the operator inserts the clamping block 6 through the insertion hole 5 and into the mounting cavity 3, positioning the two sliders 21 within the slide grooves 22. Next, the rotating rod 8 is rotated to bring the two bushings 9 closer together, thereby engaging the mounting block 4 with the clamping block 6 via the connecting rod. During this process, the stop block 12 slides into the stop groove 11. The operator then inserts the first bolt 14 through the annular groove 13 and threads it through the clamping block 6, threading it into the mounting block 4.

[0026] When the user uses the dining chair to dine and wants to place small items or take off a coat, the user can open the sealing plate 24 to separate the first magnetic strip 25 from the second magnetic strip 26, and then place the small items to be placed in the placement slot 23. Then, the placement rod 29 is slid out to separate the first magnet 31 from the second magnet 32, and then the coat is hung on the placement rod 29.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
