Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a folding chair, includes handle 1 of convenient transport, and handle 1 is made up at the top of back 2, and the both sides of back 2 are cup jointed and are installed side strutting arrangement: the middle part of the outer pipe device 3 is hinged with a seat board 4, and the hinged purpose is to enable the seat board to be folded upwards. The surface lid of bedplate 4 connects installation canvas 5, and the articulated front end strutting arrangement of front end bottom of bedplate 4: the support pipe 6 is connected and fixed with the outer pipe device 5 through a slash 7, the slash aims to ensure the stability of the device, and the connection part is fixed by a bolt group 8.

The outer tube device 3 comprises a movable sleeve 31 sleeved outside, a hole 311 is formed in the surface of the sleeve 31, an insertion tube 32 is inserted into the sleeve 31 and can slide in the sleeve at will, a spring pin 321 is formed in the position, corresponding to the sleeve 31, on the surface of the insertion tube 32, and the spring pin can be clamped when moving to the corresponding hole; if the moving length of the insertion tube needs to be changed again, the spring pin is pressed down to be separated from the hole position.

The outer tube means 3 is hinged to the seat plate 4 in order to allow the seat plate to be flipped up during retraction. The hinge portion includes: the stud 9 of welding at outer tube device 3 middle part surface, the shafting of stud 9 is cup jointed the device of guaranteeing to screw: the washer 10 and the top of the stud 9 are screwed and fixed by a bolt 11.

A pair of mounting holes 41 are formed in the bottom symmetrical position of the front end of the seat plate 4, mounting bolts 61 are inserted into the mounting holes 41, and the hole positions of the bolts correspond to the hole positions of the mounting holes and are of mounting sizes. The bolt 61 is inserted with a mounting pin 62 at the position where the hole site of the mounting hole 41 penetrates, and two end faces of the pin 62 are provided with a limiting plate 63 to prevent the middle pin from falling. The spacing between the stop plates 63 corresponds to the diameter of the pipe of the seat plate 4, which is the fitting size here.

In order to ensure that the seat board and the bracket pipe cannot be poked outwards in the process of being folded upwards. The length of the longitudinal pipe fitting of the seat plate 4 is consistent with that of the support pipe 6, and is one half of the length of the main pipe fitting of the outer pipe device 3.

The working principle is as follows: the utility model discloses a following two technical advantages: the utility model adds a handle device which is convenient to carry, so that the device can be carried more simply and conveniently after being folded; the utility model discloses a folding mode can be so that whole central part fifty percent discount along the device, has reduced the volume of device greatly, and the size of each pipe fitting corresponds each other, can not outwards stab out for the process of transport is lighter.

The specific operation is as follows: when the device needs to be retracted and folded, the bolt group 8 is screwed down firstly, so that the oblique lever 7 is separated from the bracket pipe 6 at the front end and the outer pipe device 3 at the rear end, and the two pipe fittings are released; the bolt group 8 is screwed in the oblique rod 7 to prevent the bolt group 8 from falling off, and the oblique rod 7 screwed with the bolt group 8 is placed in the seat plate 4;

loosening the gasket 10-bolt 11 device, and turning up the seat plate 4 device to enable the canvas 5 and the backrest at the top to be mutually covered;

the support tube 6 is pulled to be mutually attached to the bottom of the seat plate 4, so that the support tube 6 is retracted;

the spring pin 321 is pressed down, so that the insertion tube 32 is completely retracted into the sleeve 31, and the spring pin 321 and the hole position 311 at the top are correspondingly clamped to realize the contraction and fixation of the main keel;

the handle 1 is lifted by hand, so that the portable carrying can be realized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
