Among them, chairs made by injection molding process have higher precision and strength, and are widely used in restaurants, outdoor playgrounds and other places, and have good sales both on e-commerce platforms and in physical stores.

[0003] A new type of antibacterial plastic chair described in the publication number CN216723853U includes a support seat, a backrest is fixedly installed on the top of the support seat, a support rod is fixedly installed on the top of the backrest, and a sterilization mechanism is fixedly installed on the rear side of the backrest; the sterilization mechanism includes a water tank, a medicine box, a water delivery pipe, a spray head, an ultraviolet disinfection lamp and a fan. A water tank is fixedly installed on the rear side of the chair back, a medicine box is fixedly installed on the top of the support rod, a water delivery pipe is fixedly installed on the left side of the water tank, and a spray head is movably installed at the bottom of the medicine box. For this new type of antibacterial plastic chair, first, the water in the water tank enters the medicine box through the water inlet pipe and is sprayed out through the spray head to disinfect the support seat. Then the fan is started, and the air dries the support seat through the ventilation holes. The ultraviolet disinfection lamp is started to disinfect the support seat for the second time. Finally, the electric push rod pushes the activated carbon plate to adsorb and clean the surface of the support seat again, which is convenient for the user to sit down quickly.

[0004] Although the above-mentioned plastic chair solves certain problems, it still has the following disadvantages:

[0005] (1) The plastic chair is a whole, which occupies a large space during online shopping transportation, is not convenient for packing, and is easy to be knocked during transportation, affecting the stability between the chair connectors.

[0042] Embodiment 1:

[0043] As Figures 1 to 5 shown, this embodiment provides a spliced outdoor plastic chair, which includes a seat board 1, support side plates 2, a backrest 3, connecting columns 4, a first clamping mechanism 5, and a second clamping mechanism 6.

[0044] Among them, the seat board 1 with a downward rounded corner at the front end of the rectangle serves as the connection basis of the plastic seat. A number of uniformly distributed first ventilation holes 16 are opened on the upper side of the seat board 1 to increase the breathability of the buttocks when sitting on the chair and avoid stuffiness. A first clamping block 7 is fixedly connected to both sides of the seat board 1 at a position slightly behind. On both sides of the seat board 1 at a position behind, a first clamping internal threaded tube 8 is fixedly connected respectively before and after the first clamping block 7. Support side plates 2 are arranged on both sides of the seat board 1. First connection holes 11 for cooperating with the first clamping internal threaded tube 8 are opened at the front and back of the mutually close sides of the support side plates 2. And between the first connection holes 11, first clamping grooves 10 for cooperating with the first clamping block 7 are opened on the mutually close sides of the support side plates 2. The distance between the front and back inside the first clamping groove 10 is larger than the front and back length of the first clamping block 7. A first auxiliary clamping buckle 504 with a right-angled triangle cross-section is fixedly connected to both the front and back inside the first clamping groove 10. The inclined surfaces of the first auxiliary clamping buckles 504 face the side of the seat board 1 relatively. A first moving groove 501 is opened at both the front and back of the first clamping block 7. At the side far from the seat board 1 inside the first moving groove 501, a first elastic sheet 502 is fixedly connected to both the front and back ends that are mutually far away inside the first moving groove 501. A first main clamping buckle 503 with a triangular cross-section is fixedly connected to the side of the first elastic sheet 502 that is mutually far away and close to the seat board 1.

[0045] When the supporting side plate 2 is pressed and installed on the seat plate 1, the two first secondary buckles 504 press the two first primary buckles 503 through the inclined surfaces between the buckles, causing one end of the first elastic piece 502 connecting the first primary buckle 503 to be pressed into the interior of the first movable slot 501. After the buckles are aligned, the connection between the supporting side plate 2 and the seat plate 1 is assisted by the buckles. First bolt connection slots 19 are provided at the front and back of the mutually remote sides of the supporting side plate 2. The first bolt connection slots 19 are respectively connected in communication with the interiors of the first connection holes 11. The first bolts 20 pass through the interiors of the first bolt connection slots 19 and are threadedly connected to the interiors of the first clamping internal threaded pipes 8 to connect the supporting side plate 2 and the seat plate 1 together. Moreover, a stool leg 9 is fixedly connected to the front and back of the lower end of the supporting side plate 2, and an anti-slip cushion block 18 is fixedly connected to the lower end of each stool leg 9.

[0046] An inclined connecting column 4 is fixedly connected to the rear side of the upper end of the supporting side plate 2. The connecting column 4 inclines backward and forms an angle of 110° with the upper side plane of the supporting side plate 2, making it more comfortable when the backrest 3 is in use. The backrest 3 is located between the two connecting columns 4, and a second clamping block 12 is fixedly connected to the positions near the lower ends on both sides of the backrest 3. Second card slots 14 are provided on the mutually close sides of the connecting columns 4. Second secondary buckles 604 with a right-angled triangle cross-section are fixedly connected to the upper and lower parts inside the second card slots 14. Second movable slots 601 are provided in the upper and lower parts of the second clamping block 12, and the upper and lower parts inside the second movable slots 601 are mutually remote. A second elastic piece 602 is fixedly connected to the side remote from the backrest 3. One end of the mutually remote sides of the second elastic pieces 602 on the same side near the backrest 3 is fixedly connected to a second primary buckle 603, and the cross-section of the second primary buckle 603 is also a right-angled triangle. The connecting column 4 and the backrest 3 are connected by the second secondary buckle 604 and the second primary buckle 603 in the same way as the connection method between the supporting side plate 2 and the seat plate 1. Second bolt connection slots 21 that can communicate with the second connection holes 15 are provided in the upper and lower parts of the mutually remote sides of the connecting columns 4. The second connection holes 15 are provided in the upper and lower parts of the mutually close sides of the connecting columns 4, and the second card slots 14 are located between the second connection holes 15.

[0047] A second clamping internal threaded pipe 13 is fixedly connected to the positions near the lower parts on both sides of the backrest 3. The backrest 3 and the connecting column 4 can be connected by passing the second clamping internal threaded pipe 13 into the interior of the second connection hole 15 and using the second bolt 22 to splice the chair. A number of uniformly distributed second ventilation holes 17 are provided on the front side of the backrest 3 to avoid stuffiness on the back and increase the air permeability of the chair. During assembly, first install one side of the supporting side plate 2 with an internal hexagonal wrench, then install the backrest 3, and then install the other side of the supporting side plate 2.

[0048] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
