Embodiment Construction

[0015] A rectangular block with a cuboid through groove protrudes from the left and right sides of the lower surface of the stool respectively. Use two U-shaped steels 3 as stool legs. The top of the U-shaped steels passes through the channel of the rectangular block. There is a small difference in the distance between the U-shaped steels, and a hinge is used to fix the U-shaped steels on both sides of the equal height. Together, they form an active X-shaped installation. Slide the U-shaped steel in the front part backwards in the through groove, you can fold the two U-shaped steels in a plane, and then fold the U-shaped steels to the plane where the stool surface is located

[0016] Backrest 2 both sides middle part is connected telescopic hollow bar 6,7 with hinge, and the hollow bar other end is connected with a bar 4 usefulness that can rotate around the front end of stool face. Use one end of a bar 5 of the two-bar linkage as a support at the hinge to stabilize its mecha...

Abstract

The invention relates to a folding chair, belonging to a mechanical device realizing complete folding of a chair through a mechanical structure. According to the multi-function folding chair, a rectangular block with a through groove is arranged on the lower surface of a seat board, two pieces of U-shaped steel are placed into the through groove, the two side faces of each piece of U-shaped steel are connected into an X shape, the X-shaped device is rotated to drive the two pieces of U-shaped steel to the plane close to the seat board, and then chair legs can be completely folded into the plane close to the seat board. Telescopic hollow rods are connected to the middles of two sides of a backrest by hinges, and the other ends of the hollow rods are connected with rods capable of rotating around the front end of the seat board by hinges. One end of one rod of a two-link mechanism is taken as support at the hinging position for stabilizing the mechanism, and the other rod of the two-link mechanism is fixed in a sliding long hole above the two sides of the seat board. A control device is used for controlling the angle incline and folding of the backrest. The multi-function folding chair is simple in design mechanism, after complete folding, the multi-function folding chair is small in size and convenient to carry, in addition, the multi-function folding chair is suitable for various places, and low in price, and with the adoption of the control device, the flexibility in regulation and folding is good.

Description

Technical field: [0001] The newly invented folding chair is a mechanical device that realizes the complete folding of the chair through a mechanical structure. Background technique: [0002] At present, people's life is fast-paced and under great pressure. They all hope to have a comfortable and easy-to-carry chair and get more rest. However, the chairs on the market are either very large and inconvenient to move; or they are suitable in size but not easy to carry. Even if it is a foldable chair, most of them can only be partially folded, and the volume is still too large to be used in multiple occasions, and the price is expensive. Invention content: [0003] Compared with the current existing folding chairs, the new invention has the advantages of high cost performance, simple device structure and convenient use. A chair that folds completely into a flat surface and can be used in multiple settings. [0004] The technical solutions adopted to solve technical problems ...
