[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Embodiment 1

[0047] See also Figure 1-6 , a leisure chair with backrest angle adjustment, including a main body component 1, the main body component 1 includes: a bracket 11, a base 12 is arranged on the top of the bracket; a rotating rod 13, which is rotatably connected to the top of the base 12 through a frame; a backrest 14, which is fixedly connected to the rotating rod 13, and an adjustment component 2 is arranged on the base 12 and the rotating rod 13, and the adjustment component 2 includes: a frame 21, which is symmetrically arranged on both sides of the base 12; a plate 22, which is arranged inside the frame 21; a slider 23, which is slidably connected to the plate 22; a limiting mechanism 24, which is arranged inside the frame 21; a disc 25, which is symmetrically fixedly connected to both ends of the rotating rod 13; a rotating shaft 251, which is arranged on the opposite side of the disc 25; a limiting frame 252, which is arranged outside the disc 25; a connecting rod 26, one end of which is rotatably connected to the outside of the rotating shaft 251, and the other end is rotatably connected to the outer wall of the slider 23 through the rotating shaft 251. The limiting mechanism 24 includes: a baffle 241, symmetrically arranged between the frame 21 and the plate 22; a spring 242, symmetrically arranged between the baffles 241; a limiting block 243, arranged at one end of the spring 242 close to the plate 22, the plate 22 is provided with a through hole for the limiting block 243 to move, and the limiting block 243 has two inclined surfaces. A telescopic rod 244 is arranged at one end of the limiting block 243, and the spring 242 is sleeved outside the telescopic rod 244.

[0048] When in use, the user moves the chair to a suitable position, sits on the base 12, and uses the adjustment component 2 to adjust the inclination angle of the backrest 14. The user bends the backrest 14 to the right, and the backrest 14 drives the rotating rod 13 to rotate clockwise. The disk 25 fixedly connected to the rotating rod 13 rotates immediately, and the connecting rod 26 connected to the disk 25 through the rotating shaft 251 moves to the right. The connecting rod 26 pushes the slider 23, whose right end rotates through another rotating shaft 251, to slide on the plate body 22. The side of the limit block 243 in the through hole of the plate body 22 close to the connecting rod 26 is an inclined surface. When the slider 23 moves to the right The slider 23 contacts the inclined surface on the limit block 243, compressing the limit block 243 into the through hole of the plate body 22. When the slider 23 slides out of the range of the limit block 243, the limit block 243 is ejected by the elastic force of the spring 242. The limit block 243 limits the slider 23 from moving to the left, and the limit block 243 does not limit the slider 23 from moving to the right. When the slider 23 moves to the right, the angle between the backrest 14 and the base 12 becomes smaller. The limit blocks 243 are provided in multiple places, and the number of times the slider 23 is restricted by the limit blocks 243 increases. The user can swing the backrest 14 to the right for multiple times, so as to achieve multi-angle adjustment of the backrest 14. At the same time, the reset mechanism 27 is used to push the limit block 243 back into the plate body 22 at the same time, so that the slider 23 can return to the leftmost end and achieve another adjustment of the backrest 14. When the limit block 243 compresses the spring 242, the telescopic rod 244 and the baffle 241 prevent the spring 242 and the limit block 243 from being skewed, so that the limit block 243 cannot quickly achieve the limiting effect on the slider 23. The limit frame 252 limits the rotation angle of the disk 25 and partially blocks the rotation position of the disk 25, thereby reducing the probability of debris entering the disk 25.

[0049] Embodiment 2

[0050] On the basis of the first embodiment, an auxiliary function is added.

[0051] See also Figure 1-6 , the limit blocks 243 are symmetrically arranged in multiple groups. The frame 21 is provided with a reset mechanism 27, which includes: an electric push rod 271, which is arranged at the bottom of the frame 21, and the output shaft of the electric push rod 271 passes through and extends into the frame 21; a push plate 272, which is arranged at the top output shaft of the electric push rod 271; a push rod 273, which is symmetrically arranged at the top of the push plate 272; a switch 274, which is arranged on the right side wall of the frame 21, and the switch 274 is electrically connected to the electric push rod 271. The top of the push rod 273 has an arc surface.

[0052] There are multiple groups of limit blocks 243, which facilitates the multi-angle adjustment of the backrest 14. The principle of the reset mechanism 27 is as follows: the user presses the switch 274, and the switch 274 generates an opening signal to the two groups of electric push rods 271. The electric push rods 271 drive the push plate 272 and the push rods 273 to push into the frame 21. One end of the push rod 273 slides on the inclined surface at the top of the limit block 243. The multiple groups of limit blocks 243 are driven by the push rods 273 to retract back into the plate body 22 at the same time. At this time, the slider 23 is not limited by the limit block 243 and can slide directly to the left side of the plate body 22 to achieve the tilting of the backrest 14 to the left. The push rod 273 has an arc surface, so that the push rod 273 can better contact the inclined surface at the top of the limit block 243, avoiding the push rod 273 from failing to push the limit block 243 in time.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
