The technical scheme that its technical problem that solves the utility model adopts is: a kind of the folding seat of lying mainly comprises pillow, flexible seat surface, front foot pipe, stull pipe, hinged seat, rear foot tube, transition joint, telescoping tube, the pipe of transferring the files, end cover, end envelope, hoodle; It is characterized in that described front foot pipe is a U-shaped pipe, the two ends of front foot pipe are respectively equipped with hinged seat, are provided with the stull pipe between the hinged seat; Rear foot tube is a U-shaped pipe, and the two ends of rear foot tube are installed with respectively hinged seat, is provided with the stull pipe between the hinged seat; Pillow is arranged on the flexible seat surface, and the flexible mount surface cover is connected on the stull pipe on front foot pipe and the rear foot tube; The middle part of front foot pipe and rear foot tube is provided with transition joint, and transition joint is hinged together; The end of pipe of transferring the files is provided with the end envelope, and is hinged with rear foot tube, and the other end is provided with the end cover; One end of telescoping tube is provided with the end envelope, and is hinged with front foot pipe, and the other end is provided with hoodle, and is installed in the pipe of transferring the files.

In the utility model, described stull Guan Weiyi root straight tube, flexible seat surface is arranged on the stull pipe, makes flexible seat surface in the situation that stressed energy keeps the cross-brace power of the equilibrium of flexible seat surface, and can the distortion of two side direction centers.

In the utility model, described front foot pipe and stull pipe form rigid frame by footmuff.

In the utility model, described rear foot tube and stull pipe form rigid frame by footmuff.

In the utility model, the described pipe of transferring the files is provided with locating hole I, locating hole II, locating hole III, and the hoodle on the telescoping tube can match with locating hole I, locating hole II, angle hole III, realizes being located by connecting.

In the utility model, described front foot pipe, the pipe of transferring the files, telescoping tube have formed variable triangle mechanism, cooperate triangle rigid support between realization front foot pipe and the rear foot tube by what regulate hoodle and locating hole I, locating hole II, locating hole III on the telescoping tube.

The utility model has the advantages that: arranged in a crossed manner and hinged between front foot pipe and the rear foot tube, by the pipe of transferring the files is set between front foot pipe and rear foot tube, telescoping tube, thereby realize the angle orientation between front foot pipe and the rear foot tube, and then by the adjusting pipe of transferring the files, the length of telescoping tube is controlled by front foot pipe, rear foot tube, the pipe of transferring the files, the triangle mechanism that telescoping tube forms, control again the angle between front foot pipe and the rear foot tube, namely realize being arranged on the adjusting of the flexible seat on front foot pipe and the rear foot tube, the final adjusting that realizes the backrest of folding chair angle, therefore the utlity model has simple in structure, easy to operate, be fit to the sandy beach, camp, the characteristics such as the various occasion uses such as garden.

The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of seat folding seat of lying mainly comprises pillow 1, flexible seat surface 2, front foot pipe 3, stull pipe 4, hinged seat 5, rear foot tube 6, transition joint 7, telescoping tube 8, the pipe 9 of transferring the files, end cover 10, end envelope 11, hoodle 12; It is characterized in that described front foot pipe 3 is a U-shaped pipe, the two ends of front foot pipe 3 are respectively equipped with hinged seat 5 and stull pipe 4; Rear foot tube 6 is a U-shaped pipe, and the two ends of rear foot tube 6 are installed with respectively hinged seat 5 and stull pipe 4; Pillow 1 is arranged on the flexible seat surface 2, and flexible seat surface 2 is socketed on the stull pipe 4; The middle part of front foot pipe 3 and rear foot tube 6 is provided with the transition joint 7 that is hinged; Pipe 9 the end of transferring the files is provided with end envelope 11, and is hinged with rear foot tube 6, and the other end is provided with end cover 10; One end of telescoping tube 8 is provided with end envelope 11, and is hinged with front foot pipe 3, and the other end is provided with hoodle 12, and is installed in the pipe 9 of transferring the files.During use, when flexible seat surface 1 bears when taking a seat power, front foot pipe 3 and rear foot tube 6 bear pressure and torsional forces by stull pipe 4, and pressure direct transfers and passs ground by front foot pipe 3 and rear foot tube 6, torsional forces is by the mutual balance of rigid pressure institute of telescoping tube 8 and the pipe 9 of transferring the files, and chair is in the use state.

With reference to Fig. 2, hoodle 12 cooperates with locating hole I91, has been made of the triangular support framework of rigidity front foot pipe 3, rear foot tube 6, telescoping tube 8 and the pipe 9 of transferring the files, and the angle between front foot pipe 5 and the rear foot tube 4 is realized positioning supports, at this moment, folding seat is in the first use state.

With reference to Fig. 3, hoodle 12 separately with locating hole I91, locating hole II92, when locating hole III93 cooperates, in front foot pipe 3, rear foot tube 6, telescoping tube 8 and pipe 9 triangle mechanisms that form of transferring the files, the variation of the length of side is supported at telescoping tube 8 and pipe 9 places of transferring the files, thereby cause the variable angle between front foot pipe 3 and the rear foot tube 6, and then can realize the variation of three kinds of backrest angles, it is available that namely folding seat has three kinds of use states.

With reference to Fig. 4, when folding, after hoodle 12 breaks away from locating hole I91, locating hole II92, locating hole III93, in front foot pipe 3, rear foot tube 6, telescoping tube 8 and pipe 9 triangle mechanisms that form of transferring the files, one side length of side at telescoping tube 8 and pipe 9 places of transferring the files can be freely elongated, unfettered, therefore the angle between front foot pipe 3 and the rear foot tube 6 changes arbitrarily, when the angle adjustment between front foot pipe 3 and the rear foot tube 6 when spending near 180, be that front foot pipe 5 and rear foot tube 4 approach when overlapping, folding seat is in flat form, and smaller volume is conveniently transported and carried.

Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
