Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 8, a folding back formula chair structure, including the seat support 1 and the back of the chair 2, the 2 left and right sides of the back of the chair are equipped with the portion of bending forward, the seat support 1 includes the base body 3 and the seat face body 4, the 3 left and right sides of the base body are equipped with the portion of bending upward, the back of the chair 2 the portion of bending forward with the base body 3 corresponds the portion of bending upward rotates to be connected.

The forward bending part is positioned below the left side and the right side of the chair back 2, and the connection part of the forward bending part and the chair back body is in arc transition. The upward bending part is positioned at the rear position of the left side and the right side of the base body 3, and the connecting part of the upward bending part and the chair seat body is in arc transition. The portion of bending upwards is equipped with roating seat 31, the portion of bending forward be equipped with rotatory through-hole 21 that roating seat 31 cooperation was used, the portion of bending forward opposite side be located rotatory through-hole 21 avris is equipped with rotatory stopper 22, roating seat 31 avris be equipped with rotatory stopper 22 cooperation is used spacing arch 32.

The seat support 1 is connected with the chair back 2 in a rotating mode, when the chair is needed to be normally used, the chair back 2 only needs to be rotated to enable the chair back 2 to be vertically connected with the seat support 1, and at the moment, the rotating limiting block 22 is abutted to the limiting protrusion 32. When needs transport chair, only need rotate back of the chair 2 and make it overlap with seat support 1, at this moment, rotatory stopper 22 separates with spacing arch 32, consequently, the chair structure of this application just can reduce the transportation volume of chair under the prerequisite that does not need the dismouting chair, reduces the cost of transportation of chair, has improved user's use and has experienced the sense.
