Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model discloses the connection that mentions divide into fixed connection and can dismantle the connection, fixed connection is for the conventional fixed connection mode such as undetachable connection including but not limited to hem connection, rivet connection, adhesive connection and welded connection, can dismantle the connection including but not limited to conventional dismantlement modes such as threaded connection, buckle connection, pin joint and hinged joint, when not clearly prescribing a limit to concrete connection mode, acquiesces to always can find at least one kind of connected mode in current connected mode and can realize this function, and the technical staff in the art can select by oneself as required. For example: the fixed connection selects welding connection, and the detachable connection selects hinge connection.

The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 6, and the folding chair of the embodiment comprises a door-shaped frame 1, an arc-shaped plate 2 and a rotating shaft 3, wherein two ends of the bottom of the door-shaped frame 1 are respectively rotatably connected with the left end and the right end of the arc-shaped plate 2 through the rotating shaft 3. The arc-shaped plates 2 are U-shaped arc thin plates, and the arc-shaped plates 2 are arranged inwards in sequence and attached to each other in a plurality of numbers. The arc-shaped plate 2 is a soft wood plate with toughness, and nuts are matched with the threads at the two ends of the rotating shaft 3 and used for locking the arc-shaped plate 2 and fixing the angle.

Door type frame 1 is bottom open-ended rectangle frame construction, and door type frame 1 length L is 750mm, and door type frame 1 width W is 730mm, and door type frame 1 height H1 is 50mm, and door type frame 1 thickness D1 is 10 mm.

The number of the arc-shaped plates 2 is 13, the thicknesses D2 are the same and are 10mm, and the height H2 is 80 mm.

One end of the rotating shaft 3 is provided with a baffle 31, and the other end of the rotating shaft is processed with threads and is in threaded fit with a nut 32.

The number of the gate frames 1 is two. When the folding chair is unfolded, the two door-shaped frames 1 form a triangle, and the structure is stable.

The arc 2 is provided with anti-skidding rubber pad 4 with 3 junctions of pivot, because the extrusion effect makes the contact of anti-skidding rubber pad 4 inseparabler between the arc 2, greatly reduced relative gliding risk, fixed effect is better.

The folding chair is in a storage state as shown in figures 4-6, and is more convenient to carry and store after being stored.

The unfolding state of the folding chair is shown in figures 1-3, when in use, all the arc-shaped plates 2 are sequentially rotated, the angle of each arc-shaped plate 2 is adjusted according to actual exhibition and use requirements, and the range of the rotation angle between the outermost arc-shaped plate 2 and the door-shaped frame 1 is limited between 90 degrees and 120 degrees. Wherein two door type frame 1 and ground contact do as two impetus, and one of them and ground contact of a plurality of arc 2 do as another impetus, wholly constitute a stable triangular structure, screw up pivot one end nut 32, and every arc 2 final formation angle is fixed, because the extruded effect of antiskid rubber pad 4, makes the people sit in the space that arc 2 formed simultaneously, can not take place to sink.

The folding chair of the embodiment is suitable for home use of bedrooms, balconies or bay windows, and is also suitable for display of various occasions such as various art exhibition halls, home exhibition halls and stage props.
