Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to an anti-pinch folding chair. Background Art

[0002] Folding chairs are already common items on the market, such as Figure 1 As shown, a Chinese patent with announcement number CN220631606U discloses a folding chair. In the prior art, a folding chair realizes the folding function by using a structure such as a chain link or a hinge. Therefore, there are some gaps A at the chain links or hinge joints of the chair legs and at the chain links or hinge joints in the middle of both sides of the seat board. After a user sits on the chair, the flesh of the feet and buttocks may fall into the gaps. Once trapped, it is very easy to cause the flesh to be pinched, resulting in a poor user experience for all users. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-pinch folding chair to solve the problems of pinching flesh and poor user experience raised by the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the utility model provides an anti-pinch folding chair, comprising chair legs, the chair legs comprising two front and rear panels and two groups of side panel assemblies, the side panel assemblies comprising two hinged side panels, the front and rear sides of the side panel assemblies are respectively hinged to one side of the two front and rear panels, a plurality of chain links are arranged on the side portions of the side panels, the chain links are located on the inner side of the side panels, flat stoppers extending toward the direction of the side panel assemblies are arranged on the left and right side portions of the front and rear panels, the flat stoppers are matched with the side portions of the side panels, and a matching portion matched with the chain links is arranged on the inner side of the flat stoppers.

[0005] In the above solution, the four sides of the chair legs are designed with edging treatment, which can prevent the user from being pinched by the folded parts of the side panels and the front and rear panels when sitting on the chair, thereby improving the comfort of use. Among them, when the chair is fully opened from the folded state to form a normal use state, the flat block and the side of the side panel are aligned to form a plane structure, thus forming an edging form with an anti-pinch function. After avoiding pinching, it is naturally more comfortable to use.

[0006] In one embodiment, a plurality of mounting grooves adapted to the chain links are arranged on the inner side of the flat stopper, the matching portion includes the mounting grooves, and the chain links are rotatably arranged in the mounting grooves.

[0007] In one embodiment, the chain link includes a cylindrical body and spherical rotating blocks arranged on the upper and lower sides of the cylindrical body. The cylindrical body and the side plate are connected by a connecting block, and the upper and lower surfaces of the connecting block and the cylindrical body are flush.

[0008] In one embodiment, the mounting groove includes a first groove body for mounting the columnar body and a second groove body adapted to the spherical rotating block, and the shape of the second groove body is a half-waist groove shape.

[0009] In one embodiment, the anti-pinch folding chair includes a seat plate, the upper parts of the two front and rear plates are hinged to the front and rear sides of the seat plate respectively, the side surfaces and the top in the middle of the left and right sides of the seat plate are both flat surfaces, and the seat plate is divided into two hinged sub-plates along the middle of the left and right sides.

[0010] In the above scheme, the outer corners of the left and right sides of the seat board are flat surfaces. When the seat board is split into two sub-boards, the two sub-boards can rotate relative to each other to adapt to the folding function of the folding chair. However, when the two sub-boards are unfolded and laid flat, the middle of the side of the two sub-boards presents a flat surface structure as a whole, which is different from the above scheme. Figure 1 After the dividing board of the prior art is laid flat, there is a notch structure on the side of the dividing board, so that when the user sits on the chair, the buttocks of the user sink into the notch of the two dividing boards, and then the flesh is pinched.
