For solving the technical problem, the utility model discloses a chair frame main part, frame main part rear is equipped with first arch, and this first protruding both sides are equipped with the connecting plate with first protruding fixed connection, and wherein first bellied rear side is equipped with the locating plate with first protruding fixed connection, the connecting plate of first protruding both sides forms one with the locating plate fixed connection of rear side and overlooks the angle and be "concave" font structure, the position that the connecting plate middle part is close to the below is equipped with a first connecting hole that runs through two connecting plates, has a folding frame through this first connecting hole swing joint.

The two first bulges are respectively arranged at two sides of the rear part of the frame main body.

Wherein, a second bulge is arranged below the main body of the folding frame, the size of the structure of the second bulge is fixedly connected with the top of the first bulge by the connecting plates at two sides and the positioning plate at the rear side to form a structure with a concave top view angle and the inner part is matched, and a second connecting hole which penetrates through the second bulge is arranged at the intersection of the second connecting hole and the connecting hole,

the first connecting hole is movably connected with the second connecting hole through a shaft piece.

Wherein the thickness of the folding leg is overlapped with the surface of the chair frame main body when the folding leg is folded forwards by 90 degrees.

Wherein the thickness of the folding leg is equal to or similar to the height of the first protrusion and the second protrusion.

Advantageous effects

The utility model discloses the technique has following innovation advantage:

1. the folding is more stable.

2. Can be heightened, and is stable and not easy to shake after being heightened.

3. The function is rich.

Detailed Description

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

As shown in figures 1 to 7, the utility model relates to a folding chair capable of increasing height, which comprises a chair frame body 1, wherein two sides of the rear end of the frame body 1 are respectively provided with a first bulge 2, the structure of the first bulge 2 can be square or round, the first bulge 2 is fixedly connected with the frame body 1, the top of the first bulge 2 is provided with a connecting plate 3 which is fixedly connected and respectively connected with two sides of the first bulge 2, the connecting plate 3 is a thin plate, a positioning plate 4 which is fixedly connected is arranged in the middle of the two connecting plates 3 and at the rear of the top of the first bulge 2, the two connecting plates 3 are fixedly connected with the positioning plate 4, so that the two connecting plates 3 and the positioning plate 4 form a structure which is in a concave shape from the overlooking angle, the opening of the structure in the concave shape is in the forward direction, a first connecting hole 5 which transversely penetrates through the two connecting plates 3 is arranged at the position below the connecting plate 3 and close to the top of the first bulge 2, the first connecting hole 5 is used for connecting other parts and plays a role of movable connection, and the first connecting hole 5 plays a role of a rotating shaft center;

the folding chair further comprises a folding frame 6, the thickness of the folding frame 6 is close to the height of the first bulges 2, two first bulges 7 are arranged on two sides below the folding frame 6, the size of the second bulges 7 is matched with the concave structure formed by the chair frame body 1, the two connecting plates 3 at the tops of the first bulges 2 and the positioning plate 4, in order to facilitate the folding and the rotation of the folding frame 6, the second bulges 7 and the end parts are provided with arc transitions, the second bulges 7 are positioned in grooves formed by the two connecting plates 3 and the positioning plate 4, and simultaneously, the positions which are matched with the first connecting holes 5 in the same axis are provided with second connecting holes 8;

the folding frame comprises a frame body 1 of the chair and a shaft member 9, wherein the folding frame 6 is integrally and movably connected with the frame body 1 of the chair through the shaft member 9.

When the folding chair is used, the folding frame 6 can use the second connecting hole 9 of the second protrusion 7 and the shaft part 9 movably connected with the first connecting hole of the second connecting plate 3 as a rotating axis, an opening in front of the groove formed by the two connecting plates 3 and the positioning plate 4 as a rotating direction, the positioning plate 4 at the rear of the folding frame is a fixing plate, when the folding chair is folded, the folding frame 6 is folded forwards, the shaft part 9 is used as the axis, the folding chair is folded forwards for about 90 degrees, and the folding chair is just overlapped with the surface of the frame body 1 of the chair, so that the folding chair can be folded to reduce the occupied space, and meanwhile, the height of the chair is increased. When unfolded, the folding leg 6 is folded back by rotation so that when it reaches an approximately vertical angle, the folding leg 6 ends at the positioning plate 4 due to the positioning plate 4.

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.
