Technical Field

[0001] The utility model relates to the technical field of office chairs, and particularly relates to a new type of office chair. Background Art

[0002] Office chairs are a common type of furniture in office environments. Office chairs usually consist of a seat body, a backrest, armrests, a base, and feet. Office chairs play an important role in modern office environments. They not only provide a comfortable sitting posture but also help improve work efficiency and create a good working environment.

[0003] In modern office environments, sitting still for long periods has become the norm for many office workers. However, maintaining the same sitting posture for a long time can lead to slow blood circulation in the lower limbs, fatigue and stiffness of the lower limb muscles, and neck and cervical spine problems.

[0004] To solve the above problems, a new type of office chair is proposed in this application. Summary of the Utility Model

[0005] Based on the technical problems existing in the background art, the utility model proposes a new type of office chair.

[0006] A new type of office chair proposed by the utility model includes a seat body.

[0007] The seat body includes a seat base, a seat backrest, and seat feet. The seat backrest is installed on the seat base, and the seat feet are installed at the bottom of the seat base.

[0008] A reset rolling member is rotatably installed at the top of the seat backrest, and an elastic stretching member is installed at the center position of the bottom of the seat feet. A pull rope is connected between the reset rolling member and the elastic stretching member, and the pull rope is used to drive the reset rolling member to rotate when the elastic stretching member is stretched.

[0009] Preferably, the reset rolling member includes a rotating rod, a rolling massage part, a torsion spring, and a rope winding disc. An assembly groove is opened at the top of the seat backrest. The rotating rod is horizontally rotatably installed in the assembly groove, and one end of the rotating rod rotatably passes through the side surface of the seat backrest. The rolling massage part is fixedly sleeved on the rotating rod and is located in the assembly groove. The torsion spring is sleeved on the rotating rod and is located between the rolling massage part and the inner wall of the assembly groove, and both ends of the torsion spring are respectively connected to the rolling massage part and the inner wall of the assembly groove. The rope winding disc is installed at one end of the rotating rod. The pull rope is wound on the rope winding disc, and one end of the pull rope is connected to the outer circumference of the rope winding disc, and the other end of the pull rope is connected to the elastic stretching member.

[0010] Preferably, the rolling massage part includes a roller, which is fixedly sleeved on the rotating rod and located in the assembly groove. A plurality of circumferentially arranged rolling grooves are formed in the roller, and a plurality of balls are rotatably connected in the rolling grooves.

[0011] Preferably, the elastic stretching member includes an assembly cylinder, which is installed at the center of the bottom of the seat leg. An insertion cavity is formed in the assembly cylinder, and a spring is installed in the insertion cavity. A pull rod is arranged on the assembly cylinder and inserted into the insertion cavity and connected to the spring. One end of the pull rod away from the spring is installed with a foot pedal rod. A sliding port communicating with the insertion cavity is formed at the top of the assembly cylinder. A sliding block slidably connected to the sliding port is installed on the pull rod, and the other end of the pull rope is connected to the sliding block.

[0012] Preferably, rollers are installed on the outer side of the seat back, and the pull rope is attached to the outer circumference of the rollers.

[0013] The above technical solution of the present invention has the following beneficial technical effects:

[0014] By setting the reset rolling member, the elastic stretching member and the pull rope, an office worker can sit on the seat base, lean the back against the seat back, rest the neck against the reset rolling member, then step on the elastic stretching member with both feet and push forward forcefully. Under the elastic action of the elastic stretching member, a reciprocating motion is carried out. When the elastic stretching member makes a reciprocating motion, the reset rolling member is driven to rotate reciprocally through the pull rope, so as to perform rolling massage on the neck of the office worker. This structure is convenient for office workers to exercise the lower limbs, and can massage the neck during exercise, relieve neck fatigue, and accelerate blood circulation in the lower limbs, thereby improving the use effect of the office chair.

[0020] As Figures 1 - 3 shown, a novel office chair proposed by the present utility model includes a chair body 1;

[0021] In this embodiment, the chair body 1 includes a chair base 101, a chair backrest 102, and chair feet 103. The chair backrest 102 is installed on the chair base 101, and the chair feet 103 are installed at the bottom of the chair base 101.

[0022] In this embodiment, a reset rolling member 2 is rotatably installed at the top of the chair backrest 102, and an elastic stretching member 3 is installed at the central position of the bottom of the chair feet 103. A pull rope 4 is connected between the reset rolling member 2 and the elastic stretching member 3, and the pull rope 4 is used to drive the reset rolling member 2 to rotate when the elastic stretching member 3 is stretched.

[0023] In this embodiment, the reset rolling member 2 includes a rotating rod 21, a rolling massage part 22, a torsion spring 23, and a rope winding disc 24. An assembly groove is formed at the top of the chair backrest 102. The rotating rod 21 is horizontally rotatably installed in the assembly groove, and one end of the rotating rod 21 rotatably passes through the side surface of the chair backrest 102. The rolling massage part 22 is fixedly sleeved on the rotating rod 21 and is located in the assembly groove. The torsion spring 23 is sleeved on the rotating rod 21 and is located between the rolling massage part 22 and the inner wall of the assembly groove, and both ends of the torsion spring 23 are respectively connected to the rolling massage part 22 and the inner wall of the assembly groove. The rope winding disc 24 is installed at one end of the rotating rod 21. The pull rope 4 is wound around the rope winding disc 24, and one end of the pull rope 4 is connected to the outer circumference of the rope winding disc 24, and the other end of the pull rope 4 is connected to the elastic stretching member 3. The rolling massage part 22 includes a roller 221. The roller 221 is fixedly sleeved on the rotating rod 21 and is located in the assembly groove. A plurality of circumferentially arranged rolling grooves are formed in the roller 221, and a plurality of balls 222 are rotatably connected in the plurality of rolling grooves.

[0024] In this embodiment, the elastic stretching member 3 includes an assembly cylinder 31. The assembly cylinder 31 is installed at the central position of the bottom of the chair feet 103.
