Folding chair

Technical Field

The utility model relates to the technical field of daily necessities, concretely relates to folding chair.

Background

The folding chair is a portable chair with a folding function, is convenient to move and saves space. Originally for military use. The device is commonly used in various training institutions, schools at all levels, public places, hospitals, restaurants, hotels, companies, families and other places.

Current folding chairs generally come in two categories: firstly, the foldable frame and a soft material are used for manufacturing, and secondly, the foldable frame is used for manufacturing the whole body; the two types of the foldable chair have the defect of instability, so that people sit on the foldable chair like a rocking chair or a hammock, the foldable chair does not have a firm feeling, and the foldable chair still occupies a large space after being folded.

Many people go out and want the chair to have the same firm and stable feeling as the chair at home, which is not available in the existing folding chairs that provide the convenience of folding and carrying but sacrifice the firm and stable.

Disclosure of Invention

The utility model aims at solving the problems that people in the prior art sit like a rocking chair or a hammock without firm feeling and still occupy a large space after folding, and providing a novel folding chair.

The utility model relates to a folding chair, the scheme does not adopt any soft material for whole, makes whole not have like the uneven sensation of rocking chair or hammock, adopts inseparable locating hole and the bellied combination in location simultaneously, makes whole firm, and the size after folding in addition is extravagant unnecessary space yet.

In order to solve the technical problem, the utility model relates to a folding chair, which comprises a folding top plate, two first supporting rods and two second supporting rods, and comprises a first folding rod and a second folding rod which are respectively and movably connected between the first supporting rod and the second supporting rod, wherein the first folding rod is hinged with the first supporting rod, the second folding rod is hinged with the second supporting rod, the side surface between the first folding rod and the second folding rod is hinged,

the top of the second supporting rod is provided with a positioning hole,

the folding top plate is arranged above the two first supporting rods and the two second supporting rods, the rear end of the folding top plate is hinged to the two first supporting rods, and positioning protrusions matched with the positioning holes are arranged at the bottoms of the two sides of the front end of the folding top plate.

As an optimized implementation scheme of the folding chair of the utility model, the rotation radius of the folding top plate taking the hinge as the axis is equal to the length from the first supporting rod to the second supporting rod.

The utility model relates to a folding chair, which comprises a folding top plate, two first supporting rods and two second supporting rods, wherein a first folding rod and a second folding rod are hinged between each first supporting rod and each second supporting rod,

the folding top plate is hinged above the first supporting rods, the rear end of the folding top plate is hinged with the two first supporting rods, the folding top plate takes the hinges as a folding axis, the front end of the folding top plate is provided with a positioning bulge,

the top of the second supporting rod is provided with a positioning hole matched with the positioning bulge,

the total length of the first supporting rod, the second supporting rod, the first folding rod and the second folding rod is equal to that of the folding top plate, and the positioning hole of the second supporting rod and the positioning bulge of the folding top plate are located in the same axis.

The utility model relates to a folding chair, side hinged joint between first folding rod and the second folding rod.

Technical effects

The utility model discloses the technique has following innovation advantage:

1. the whole body does not adopt any soft material, so that the whole body does not have the uneven feeling like a rocking chair or a hammock;

2. the tight combination of the positioning hole and the positioning bulge is adopted, so that the whole body is stable;

3. the whole body is folded tightly, and no redundant space exists between the folded parts, so that the occupied space is reduced.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 8, the folding chair of the present invention comprises a folding top plate, two first struts 1 and two second struts 2 at the rear end of the whole chair, wherein the two first struts 1 and the two second struts 2 form a longitudinal square main frame, a first folding bar 3 and a second folding bar 4 are movably connected between each first strut 1 and the second strut 2, the first folding bar 3 and the second folding bar 4 are connected by a hinge 5, the first folding bar 3 and the second folding bar 4 are horizontally folded inward or outward, the hinge 5 is connected to the inner side or the outer side of the first folding bar 3 and the second folding bar (the first folding bar 3 and the second folding bar 4 are horizontally folded outward when connected to the inner side, and the first folding bar 3 and the second folding bar 4 are folded inward when connected to the outer side), the other end of the first folding bar 3 is connected to the hinge 5 of the first strut 1, the other end of the second folding rod 4 is hinged with the second support rod 2, so that each of the first support rod 1, the second support rod 2, the first folding rod 3 and the second folding rod 4 is of a 'door' -shaped frame structure when viewed from the side; the structure is a straight-line structure when being stretched from the overlooking angle, and is a letter V-shaped structure when being folded.

The two first supporting rods 1 are hinged through a folding top plate 7, the two first supporting rods 1 are connected to two sides of the rear end of the folding top plate 7, and the width between the two first supporting rods 1 is determined through the folding top plate 7; meanwhile, the folding top plate 7 takes the hinge 5 movably connected with the first supporting rod 1 as the axis of a folding rotating shaft, and the folding top plate is folded forwards to just cover the two first supporting rods 1 and the two second supporting rods 2; the total length of the first support rod 1 and the second support rod 2 connected with the hinge 5 after stretching is equal to the length of the folding top plate 7;

in order to make the whole frame more stable, a positioning hole 6 is further arranged above the second supporting rod 2, positioning protrusions 8 are arranged on two sides of the front end portion of the folding top plate 7, the positioning protrusions 8 are matched with the positioning hole 6, and when the folding top plate 7 covers the first supporting rod 1 and the second supporting rod 2 through the rotating and folding center of the hinge 5, the positioning protrusions 8 and the positioning holes 6 are just positioned on the same axis and are matched and fixed.

The using method comprises the following steps: when folding chair is opened to needs, two first branches 1 are fixed motionless, with two second branches 2 outwards extensions, first folding rod 3 and the second folding rod 4 that will be in fold condition are stretched out, again will fold roof 7 and use hinge 5 to fold forward as rotation center, make it cover in

first branch

1 and 2 tops of second branch, form a complete chair structure, the protruding 8 interior fixed connection of locating hole that just blocks into 2 tops of second branch simultaneously with the location of 7 tip of folding roof, make whole frame more firm. When the folding device needs to be folded, the folding top plate 7 is pulled upwards, the clamping buckles of the positioning protrusions 8 and the positioning holes 6 are separated, the folding top plate 7 is folded backwards by taking the hinge 5 as an axis, the folding top plate is rotated for 270 degrees and is positioned at the rear parts of the two first supporting rods 1, and meanwhile, the two second supporting rods 2 are pushed backwards, so that the first folding rod 3 and the second folding rod 4 are folded from a straight-line structure to a V-shaped structure.

The embodiments of the present invention have been described with reference to the accompanying drawings, but these descriptions should not be construed as limiting the scope of the present invention, which is defined by the appended claims, and any modification based on the claims is the scope of the present invention.
