Embodiment 1

[0037] Figure 1 to Figure 5 As shown, the present invention includes four uprights 3, two front extension rods 1-2, two rear extension rods 1-1 are set on the said uprights 3, as Figure 4 , Pic 4-1 As shown, the front extension rod 1-2 can be sleeved on the column 3 in the form of an inner sleeve or an outer cover, and the telescopic foot 6 is inserted below the column 3 . The lower ends of the columns 3 are each provided with a lower bracket 5, and the rear extension rod 1-1 is provided with two upper brackets 2, and the two upper brackets 2 can slide on the rear extension rod 1-1; The extension rod 1-2 is provided with two upper brackets 2, wherein one upper bracket 2 is fixed on the upper end of the front extension rod 1-2, and the other upper bracket 2 can slide on the front extension rod 1-2. The columns 3 are connected by X-shaped hinge rods 4, and the two upper brackets 2 are respectively connected to the lower brackets 5 of the columns 3 on the adjacent side throu...

Embodiment 2

[0045] On the basis of Embodiment 1, all rear extension rods 1-1 are provided with backrest connecting rods 11, Image 6 As shown, one of the upper brackets 2 is relatively fixed to the rear extension rod 1-1, and the backrest connecting rod 11 is provided on the relatively fixed upper bracket 2 . Backrest connecting rod 11 is provided with joint energy 180 degree of turning over, and two backrest connecting rods 11 are pulled up and set cloth piece as backrest. A joint 12 is provided between the backrest connecting rod 11 and the extension rod 1 , the joint 12 is an adjusting fastener 12 - 1 , and the adjusting fastener 12 - 1 is used to fix the turning angle of the backrest connecting rod 11 .

Embodiment 3

[0047] Figure 7 to Figure 10Among them, the present invention comprises four uprights 3, and described upright 3 is provided with an upper bracket 2 and a lower bracket 5, and lower bracket 5 is fixed on the bottom of upright 3, and upper bracket 2 can slide along upright 3. Each column 3 is connected with an X-shaped hinge rod 4, and the X-shaped hinge rod 4 is connected to the adjacent upper bracket 2 and the lower bracket 5. The X-shaped hinge bar 4 is divided into front side 8, rear side 10 and left and right sides 9, the X-shaped hinge bar 4 lengths of the left side and the right side are the same, and the X-shaped hinge bar 4 lengths of the front side 8 and the rear side 10 are different, when When the X-shaped hinge bar 4 is stretched, the angle between the adjacent surfaces of the X-shaped hinge bar 4 is limited by the length of the X-shaped hinge bar 4 on each surface, so that the four stool surfaces of the upper bracket 2 on each column 3 The support points form a ...

Abstract

The invention provides a folding chair frame structure with a trapezoidal stool surface, and belongs to the technical field of folding chairs. The folding chair frame structure comprises four upright columns. Upper supports and lower supports are arranged on the upright columns, every two adjacent upright columns are respectively connected with the corresponding upper supports and the corresponding lower supports on the corresponding upright columns by four ends of a corresponding X-shaped hinge rod, four side surfaces are formed by the X-shaped hinge rods and include a front side, a left side, a right side and a rear side, the adjacent side surfaces of the X-shaped hinge rods are connected with one another in a horizontal swinging manner, the sizes of the X-shaped hinge rods on the front side and the rear side are different from one another, the sizes of the X-shaped hinge rods on the left side and the right side are identical to one another, the upper supports are relatively slidably arranged on the upright columns, and angles between the adjacent surfaces of the X-shaped hinge rods can be changed under the constraint effects of the sizes of the X-shaped hinge rods on various surfaces of the folding chair frame structure when the X-shaped hinge rods are unfolded, so that a trapezoidal stool surface support structure can be formed by the upper supports on the four upright columns. The folding chair frame structure has the advantages that the stool surface is of a trapezoidal structure, and accordingly people can sit on the folding chair frame structure conveniently; the X-shaped hinge rods of a chair can be completely folded, and can be prevented from being affected by angles of a trapezoid even when unfolded.

Description

technical field [0001] The invention belongs to the technical field of folding chairs, in particular to a folding chair frame structure with a trapezoidal stool surface. Background technique [0002] With the development of the outdoor leisure industry, the requirements for the shape and ease of use of leisure products continue to increase. The beach folding chairs and fishing chairs that are more commonly used at present are relatively simple in product structure and shape, and most of the stool surfaces adopt rectangular and square structures. , rigid shape and other problems, for this reason, the folding chair frame structure of the present invention is based on the leisure sitting posture and action of the human body, and the characteristics such as wide front and narrow rear are presented as the basis, so as to realize the folding chair frame with compact folding and trapezoidal structure of the stool surface, Because the structure of the backrest is narrowed, the mater...
