[0025] Reference Figure 1-4A snap-fit ​​chair seat mounting structure includes a chair seat 1 and a chair frame 2. The chair frame 2 includes a leg 21 and a connecting seat 22 welded and fixed to the upper part of the leg 21. The connecting seat 22 has a front snap groove 221 with a front opening at its front end and a top snap groove 222 with a top opening at its rear end. The top snap groove 222 has an inner snap groove 223. The chair seat 1 is provided with a snap-fit ​​structure for snap-fitting the chair seat 1 onto the chair frame 2. The snap-fit ​​structure includes a front snap part 11 and a top snap part 12 connected to the bottom of the chair seat 1. The front snap part 11 snaps into the front snap groove 221 from the front opening of the front snap groove 221. The top snap part 12 snaps into the top snap groove 222 from the top opening of the top snap groove 222. The top snap part 12 has an inner snap part 13 that snaps into the inner snap groove 223.

[0026] After the front buckle 11 is fastened into the front buckle groove 221 and in place, the seat 1 cannot move backward, up, down, left, or right relative to the chair frame 2. When the top buckle 12 is fastened into the top buckle groove 222 and the inner buckle 13 is fastened into the inner buckle groove 223, the seat 1 cannot move forward, backward, up, down, left, or right relative to the chair frame 2. In this way, the seat 1 is fastened onto the chair frame 2 through the cooperation of the buckle structure and the connecting seat 22. The structure is simple and easy to install, and it can connect the seat 1 and the chair frame 2 without bolts, eliminating the disadvantage of needing tools to install the seat and effectively improving the ease of installation of the seat 1.

[0027] In this embodiment, there are at least two connecting seats 22 arranged from left to right on the upper part of the leg frame 21, and each connecting seat 22 corresponds to a buckle structure, thereby improving the structural stability of the seat 1 being buckled onto the chair frame 2.

[0028] In this embodiment, the connecting seat 22 is a square tube welded and fixed to the leg frame 21. The front opening of the square tube and the front section of the inner cavity of the square tube form the front buckle groove 221. A buckle inlet is provided on the rear end of the top surface of the square tube. The buckle inlet and the rear section of the inner cavity of the square tube form the top buckle groove 222. The inner buckle groove 223 is located in the rear section of the inner cavity of the square tube. The inner buckle groove 223 penetrates the outside of the square tube, so as to facilitate the inner buckle part 13 to exit the inner buckle groove 223 from the outside of the square tube when the seat 1 needs to be disassembled later.

[0029] In this embodiment, the front buckle 11 includes an insertion body 111 connected to the bottom of the seat 1 and an insertion part 112 fixedly connected to the rear side of the insertion body 111. The insertion body 111 is integrally formed and connected to the seat 1, and the insertion part 112 is integrally formed and connected to the insertion body 111, thereby ensuring the structural stability of the front buckle 11. The rear side of the insertion body 111 abuts against the front end of the connecting seat 22, thereby restricting the seat 1 from moving further backward. The insertion part 112 is inserted into the front buckle groove 221, thereby preventing the seat 1 from moving up, down, left, or right.

[0030] Furthermore, the front side of the insertion body 111 is provided with multiple reinforcing ribs 113. The rear end of the reinforcing ribs 113 is integrally formed and connected to the insertion body 111, and the upper part is integrally formed and connected to the bottom of the seat 1. The reinforcing ribs 113 are used to improve the structural stability of the insertion body 111.

[0031] Furthermore, the insertion part 112 includes an insertion body 1121 integrally formed and connected to the rear side of the insertion body 111, and a plurality of mating protrusions 1122 integrally formed on the outer peripheral surface of the insertion body 1121. The mating protrusions 1122 are used to contact the groove surface of the front snap-fit ​​groove 221. By having the mating protrusions 1122 contact the groove surface of the front snap-fit ​​groove 221, the contact area between the insertion part 112 and the groove surface of the front snap-fit ​​groove 221 can be reduced, thereby reducing friction and facilitating the insertion part 112 to be inserted into the front snap-fit ​​groove 221 to form a snap-fit.

[0032] In this embodiment, the top surface of the connecting seat 22 is an inclined support surface 220. The inclined support surface 220 extends inclinedly backward and downward from the front end. The buckle structure also includes a support part 14 integrally formed with the seat 1. When the front buckle part 11 is fastened into the front buckle groove 221 and the top buckle part 12 is fastened into the top buckle groove 222, the support part 14 presses against the inclined support surface 220, thereby allowing the connecting seat 22 to support the seat 1.

[0033] Furthermore, each top buckle 12 is connected to at least two support parts 14 distributed from left to right on both the front and rear sides. The front end of the support part 14 located at the front end of the top buckle 12 has a clearance gap with the front buckle 11, which facilitates the demolding of the front buckle 11 during the injection molding process with the seat 1, and also facilitates the front buckle 11 to be fastened into the front buckle groove 221.

[0034] In this embodiment, each top buckle 12 has two inner buckle parts 13 arranged opposite to each other, and each inner buckle part 13 is matched with an inner buckle groove 223, thereby improving the stability of the top buckle part 12 in the top buckle groove 222.

[0035] In this embodiment, the inner buckle 13 includes a buckle strip 131 and a buckle part 132. The upper part of the buckle strip 131 is integrally formed and connected to the top buckle part 12, and the lower part is integrally formed and connected to the buckle part 132. The cross-section of the buckle part 132 is trapezoidal, and the width of the cross-section of the buckle part 132 gradually decreases from top to bottom, so as to facilitate the buckle part 132 to be fastened into the top buckle groove 222 and to cooperate with the inner buckle groove 223.

[0036] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
