Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, the present embodiment provides an elastic base of a chair, which includes an upper horizontal tube 1, a lower horizontal tube 2 and a connecting plate 3, wherein the upper horizontal tube 1 is suspended to form a cantilever, and the lower horizontal tube 3 is used for supporting on the ground; the connecting plate 3 at least comprises an upper connecting piece 31, a lower connecting piece 32 and an elastic piece 33 formed between the upper connecting piece 31 and the lower connecting piece 32, the upper connecting piece 31 is connected with the upper transverse tube 1, the lower connecting piece 32 is connected with the lower transverse tube 2, the elastic piece 33 can deform under the action of pressure, the shaking function is realized by utilizing the lever principle and the elasticity of the elastic piece, so that the back is relaxed and comfortable; compared with the bundle type folding chair with the same shaking function in the market, the elastic chair base has the advantages of simple structure, low cost, low weight, low installation difficulty and low noise.

Install the elastic base that this embodiment provided in the chair body bottom side of rocking chair, the rocking chair can supply the people to take, because the chair body is installed in cantilever structure's last horizontal pipe to go up horizontal pipe and be supported by the elastic component, consequently folding chair body can produce elasticity and rock, provides leisure use and experiences.

In this embodiment, the whole elastic steel plate that is of connecting plate 3, the connecting plate be the C template, the C template is connected in elastic base's front side, just the C template is open towards the rear side.

Compared with the existing elastic base, the elastic base provided by the embodiment has the advantages that the upper support frame and the lower support frame are omitted, so that the elastic base is simple in structure, convenient to install, low in cost and low in noise.

Specifically, the C-shaped plate is fixed on the upper transverse pipe and the lower transverse pipe through bolts and

nuts

5,6.

Optionally, the front and rear sides of the upper cross tube are respectively provided with a front mounting seat 71 and a rear mounting seat 72, and the front mounting seat 71 and the rear mounting seat 72 are used for connecting the chair body.
