[0019] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a free folding outdoor armchair, comprising two brackets 1 arranged at the front and rear and a chair back 3 arranged between the two brackets 1, the bracket 1 plays the role of a corresponding component of the support, the chair back 3 is convenient for the user to lie down, a support plate 2 is fixedly arranged on the top of the bracket 1, the support plate 2 is used to support the user's arm, and a connecting shaft 4 is fixedly arranged at the bottom position of the front and rear surfaces of the chair back 3, and the connecting shaft 4 is used to connect the chair back 3, and a through groove 5 is opened on the opposite side of the two brackets 1, and the through groove 5 is used to set the corresponding components, and a limiting groove 6 is surrounded by the side away from the chair back 3 in the through groove 5, and the limiting groove 6 is used to cooperate with the pin rod 7, and the opposite sides of the front and rear connecting shafts 4 extend to the inside of the through groove 5 and the inside of the connecting shaft 4 is provided with a cavity, and the opposite sides of the two connecting shafts 4 are fixedly provided with an arc block 11 by a spring, and the arc block 11 can drive the pin rod 7 to perform telescopic activities, and four pin rods 7 are arranged around the top of the connecting shaft 4 by a spring, and the pin rod 7 plays the role of limiting.

[0021] Furthermore, a seat plate 8 is fixedly provided on one side opposite to the two brackets 1, wherein the seat plate 8 is convenient for the user to lie down.

[0022] Furthermore, an auxiliary support rod 9 is movably provided at one side of the bottom of the seat plate 8 through a hinge, wherein the auxiliary support rod 9 plays a role of auxiliary support.

[0023] Furthermore, the through slot 5 adopts a front-to-back through-type design, and one side of the through slot 5 close to the connecting shaft 4 is movably connected to the connecting shaft 4 via a bearing, wherein the through slot 5 is used to set corresponding components.

[0024] Furthermore, the opposite sides of the two connecting shafts 4 are both threadedly connected with adjusting screws 10, and the opposite sides of the two adjusting screws 10 both penetrate the connecting shafts 4 and contact the arc stop blocks 11, and the outer surface of the arc stop blocks 11 contact the pin rod 7, wherein the adjusting screws 10 can drive the arc stop blocks 11 to move.

[0025] Furthermore, the opposite sides of the two pins 7 penetrate the connecting shaft 4 and extend to the inside of the limiting groove 6, and the pins 7 are clamped with the limiting groove 6, wherein the pins 7 are used to play a limiting role.

[0026] Furthermore, there are a plurality of limiting grooves 6 , and every two limiting grooves 6 are designed to be equidistant from each other, wherein the limiting grooves 6 are used to cooperate with the pin rod 7 .

[0027] Working principle: When it is necessary to adjust the device, the user first twists the adjusting screw 10 outward to release the limit on the arc stop block 11, so that the arc stop block 11 moves outward at the high arc position, and when the arc stop block 11 moves, due to the setting of the height difference, the pin rod 7 moves slowly and releases the limit on the limit groove 6. Then the user adjusts the chair back 3. When the chair back 3 is adjusted to a suitable angle, the user twists the adjusting screw 10 inward to move the arc stop block 11, so that the arc stop block 11 pushes the pin rod 7 up to engage with the limit groove 6, thereby limiting the chair back 3.

[0028] According to the above working process, we can know:

[0029] The free-folding outdoor armchair, by providing a limit groove 6, a pin rod 7, an adjustment screw 10 and an arc stop block 11, allows the user of the device to conveniently adjust the angle of the chair back 3, and the angle adjustment has a high degree of freedom, which can facilitate the user to adjust to a suitable position, bringing a good user experience to the user, bringing convenience to the user, improving the practicality of the device, and meeting the user's usage needs.
