Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] See also Figure 1-5 The utility model provides a lunch break chair with a height adjustment mechanism, including a base frame 1, a rear support frame 2 is installed at the bottom rear end of the base frame 1, a front support rod 4 is installed at the bottom front end of the base frame 1, the rear support frame 2 is rotatably connected to the bottom end of the backrest movable frame 3, a backrest adjustment mechanism 6 is installed at the left end of the front bottom of the backrest movable frame 3, and an auxiliary function mechanism 7 is installed at the front middle of the rear support frame 2;

[0024] The backrest adjustment mechanism 6 includes a fixing frame 1 601 and a fixing frame 2 603. The fixing frame 1 601 is installed at the middle left end of the front bottom of the backrest movable frame 3, and the fixing frame 2 603 is installed at the middle left end of the rear side of the front support rod 4. The middle part of the fixing frame 1 601 is rotatably connected to the bottom end of the cylinder body of the pneumatic telescopic rod 602, and the top end of the rod body of the pneumatic telescopic rod 602 is rotatably connected to the middle part of the fixing frame 2 603. When sitting on the seat plate 12, the back leans against the backrest 9 and the backrest movable frame 3, and the back leans back, and the output end of the pneumatic telescopic rod 602 is extended to stretch the pneumatic telescopic rod 602 as a whole. The output end of the pneumatic telescopic rod 602 is higher than the bottom of the cylinder body. When the output end of the pneumatic telescopic rod 602 is extended, the backrest movable frame 3 is rotated backward on the rear support frame 2 to pull the distance between the backrest 9 and the seat plate 12 apart, so as to change the tendency from sitting to lying. The angle is adjusted according to needs, and the adjustment angle is 92 degrees to 135 degrees.

[0025] The auxiliary function mechanism 7 includes a vertical support column 701, the rear end of the vertical support column 701 is installed in the middle of the front side of the rear support frame 2, the interior of the vertical support column 701 is slidably connected to the rear of the movable lever 702, the rear of the movable lever 702 is located at the front end of the vertical support column 701 and is sleeved with a fastening sleeve 703, the front end of the movable lever 702 is installed with a horizontal lever 704, the left and right sides of the horizontal lever 704 are rotatably connected with movable footrests 705, when the movable footrests 705 need to be used, the movable lever 702 is pulled out from the interior of the vertical support column 701, and then the movable footrests 705 on both sides are flipped into a plane so that the feet can be placed on it, thereby increasing the comfort of the feet and legs.

[0026] The movable foot pedal 705 on the right side is engaged with the foot pedal buckle 13, and the foot pedal buckle 13 is installed at the middle and rear end of the bottom right side of the base frame 1. When the movable foot pedal 705 is not needed, the movable foot pedal 705 is retracted into the vertical support column 701, and then the movable foot pedal 705 is engaged with the foot pedal buckle 13, and the movable foot pedal 705 is fixed at the bottom of the base frame 1.

[0027] Movable leg rods 5 are installed at the rear ends of the left and right sides of the bottom of the base frame 1. The bottoms of the two movable leg rods 5 are respectively installed on the left and right sides of the supporting legs 8. The movable leg rods 5 are inserted into the supporting legs 8. There is an automatic telescopic rod inside the supporting legs 8, which can drive the movable leg rods 5 to adjust the lifting and lowering.

[0028] A backrest 9 is installed on the front side of the backrest movable frame 3, and a seat plate 12 is installed on the top of the base frame 1. Air holes 11 are equidistantly distributed on the backrest 9 and the seat plate 12. The air holes 11 increase the air permeability of the backrest 9 and the seat plate 12 when in use, which facilitates heat dissipation needs under long-term use.

[0030] The angle between the upper part of the movable backrest frame 3 and the rear side of the base frame 1 is 92 degrees to 135 degrees. If it is too straight, it becomes a backrest chair, lacking the beauty of lines. If it is too oblique, it becomes a reclining chair. The curvature should be such that the protruding part of the upper end of the backrest should coincide with the curved part of the back of the head and the neck of the person. The seat panel 12 is less than 10 cm higher than the movable footrest 705. When sitting on the lunch break chair, the feet are placed on the movable footrest 705, and the height of the feet is lower than the seat panel 12 to increase comfort. If the position of the footrest is too low when sitting on the chair, the legs are prone to swelling, and if it is too high, the leg muscles are easily pulled.

[0031] In the utility model, the lunch break chair can adjust the angle quickly and conveniently. Specifically, when sitting on the seat plate 12, the back rests on the backrest 9 and the backrest movable frame 3, the back leans back, the output end of the pneumatic telescopic rod 602 is extended, the pneumatic telescopic rod 602 is completely stretched, the output end of the pneumatic telescopic rod 602 is higher than the bottom of the cylinder body, and when the output end of the pneumatic telescopic rod 602 is extended, the backrest movable frame 3 is turned backward on the rear support frame 2 to open the distance between the backrest 9 and the seat plate 12, and the tendency of lying down from sitting is formed. The angle is adjusted according to needs, and the adjustment angle is 92 degrees to 135 degrees;

[0032] The nap chair can increase the comfort of the legs and feet when in use. Specifically, when the movable footrest 705 is needed, the movable lever 702 is pulled out from the inside of the vertical support column 701, and then the movable footrests 705 on both sides are flipped into a flat surface so that the feet can be placed on it, thereby increasing the comfort of the feet and legs.
