Description

Technical Field

[0001] This utility model pertains to daily necessities, specifically a folding chair. Background Technology

[0002] Outdoor activities often require carrying chairs for rest, making outdoor folding chairs an essential item for people engaging in outdoor activities. However, existing folding chairs are cumbersome to fold and have low stability when unfolded. Utility Model Content

[0003] This utility model provides a folding chair.

[0004] The purpose of this invention is to solve the problems of some existing folding chairs being troublesome to fold and having low stability after unfolding.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A folding chair according to this utility model includes a chair frame and armrests provided on the chair frame. The chair frame includes a U-shaped back tube, a U-shaped seat tube, a U-shaped rear tube, two front tubes, two fixing plates, and a U-shaped reinforcing tube. The ends of the two arms of the U-shaped rear tube are pivotally connected to the middle of the corresponding fixing plates. The arms of the two arms of the U-shaped back tube are pivotally connected to the rear of the corresponding fixing plates. The upper parts of the two front tubes are pivotally connected to the corresponding fixing plates. The front part of the fixed plate is pivotally connected; a U-shaped reinforcing tube is connected between the legs of the two front tubes; the two arm ends of the U-shaped back tube are respectively pivotally connected to U-shaped connectors via long pivots; the two arms of the U-shaped seat tube extend into the U-shaped grooves of the corresponding U-shaped connectors and are pivotally connected to the U-shaped connectors; the front parts of the two arms of the U-shaped seat tube are respectively pivotally connected to the upper middle part of the corresponding front tube; a pair of connecting pieces are respectively pivotally connected to the middle part of the two arms of the U-shaped rear tube, and the other end of the pair of connecting pieces is pivotally connected to the long pivot.

[0006] Preferably, the long pivot passes through the U-shaped connector, the end of the U-shaped back tube arm, and a pair of connecting plates.

[0007] The beneficial effects of this utility model are: the folding chair of this utility model is convenient to open for outdoor use and has good stability after unfolding. Folding it is also very simple. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0010] As shown in the figure, the folding chair of this utility model includes a chair frame and armrests 2 and 9 mounted on the chair frame. The chair frame includes a U-shaped back tube 1, a U-shaped seat tube 8, a U-shaped rear tube 3, a front tube 5, a front tube 7, a fixing plate 10, a fixing plate 14, and a U-shaped reinforcing tube 6. The ends of the two arms of the U-shaped rear tube 3 are pivotally connected to the middle of the fixing plates 10 and 14; the arms of the two arms of the U-shaped back tube 1 are pivotally connected to the rear of the fixing plates 10 and 14; the upper part of the front tube 5 is pivotally connected to the front of the fixing plate 14, and the upper part of the front tube 7 is pivotally connected to the front of the fixing plate 10; a U-shaped reinforcing tube 6 connects the legs of the front tubes 5 and 7; one arm of the U-shaped back tube 1 is pivotally connected to a U-shaped connector 13 via a long pivot 12, and the other arm is pivotally connected to another U-shaped connector 16 via another long pivot 15.

[0011] One arm of the U-shaped seat tube 8 extends into the U-shaped groove of the U-shaped connector 13 and is pivotally connected to the U-shaped connector 13. The other arm of the U-shaped seat tube 8 extends into the U-shaped groove of another U-shaped connector 16 and is pivotally connected to the U-shaped connector 16. The front parts of the two arms of the U-shaped seat tube 8 are pivotally connected to the upper middle parts of the front tube 5 and the front tube 7, respectively.
