[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It should be understood that the implementation methods described herein are only used to explain this application and are not used to limit this application.
[0020] The utility model provides the following Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A new type of office chair shown in the figure comprises a seat 1 and a seat back 2 fixedly connected to the seat 1, a chair leg 3 is fixedly connected to the bottom of the seat 1, a fixing plate 4 is fixedly connected to the top of the seat back 2, a headrest 5 is provided on the front side of the fixing plate 4, a threaded rod 6 rotatably connected to the headrest 5 and a guide rod 7 fixedly connected to the headrest 5 are passed through the fixing plate 4, a knob 9 is fixedly connected to the end of the threaded rod 6 away from the headrest 5, columns 10 are fixedly connected to both sides of the seat 1, a limiting sleeve 11 is sleeved on the outer side of the column 10, fixing grooves are provided on both sides of the column 10 and a spring 12 is provided in the fixing groove, a limiting block 13 passing through the side wall of the limiting sleeve 11 is provided at one end of the spring 12, and an armrest plate 14 is fixedly connected to the top of the limiting sleeve 11.
[0021] like Figure 1 and Figure 3 As shown, in the utility model, an opening is provided on the chair back 2 and a plurality of fixing rods 15 fixedly connected to the chair back 2 are provided at the opening, and a rotating roller 16 is rotatably connected to the outer side of the fixing rod 15 to massage the user's back.
[0022] like Figure 4 As shown, in the present invention, one end of the threaded rod 6 is rotatably connected to the headrest 5 via a bearing 8, thereby improving the stability of the threaded rod 6 during rotation.
[0023] like Figure 4 As shown, in the utility model, the threaded rod 6 is threadedly connected with the fixing plate 4, and the fixing plate 4 is provided with a thread groove for the threaded rod 6 to pass through and a guide groove for the guide rod 7 to pass through.
[0024] like Figure 1 , Figure 2 , Figure 3 As shown, in the utility model, a plurality of limiting holes matched with the limiting blocks 13 are provided on both side walls of the limiting sleeve 11 , so that the height of the limiting sleeve 11 can be changed, thereby facilitating the adjustment of the height of the armrest board 14 .
[0025] like Figure 1 and Figure 3As shown, in the utility model, two openings 2 are provided on the armrest board 14 and a plurality of fixing rods 2 17 fixedly connected to the armrest board 14 are provided at the openings 2. The outer side of the fixing rods 2 17 is rotatably connected to a rotating roller 2 18 to massage the user's hands.
[0026] Working principle: In the specific implementation of the utility model, since the rotating roller 16 is rotatably connected to the fixed rod 15, and the rotating roller 2 18 is rotatably connected to the fixed rod 2 17, the user can sit on the seat 1, and the rotating roller 16 rotates around the fixed rod 15, and the rotating roller 2 18 rotates around the fixed rod 2 17, which can massage the back and hands of the user and improve the user's comfort; at the same time, the limit block 13 can be pressed to move it into the fixed groove. At this time, the spring 12 is in a compressed state, so the limit sleeve 11 can be changed. The height is adjusted, and then the limit block 13 is released. The elastic potential energy of the spring 12 restores it to its original state, so that the limit block 13 moves into the limit groove, and the limit sleeve 11 is limited and fixed, thereby adjusting the height of the armrest board 14; the knob 9 can be rotated to drive the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the fixing plate 4, and the threaded rod 6 is rotatably connected to the headrest 5 through the bearing 8, the threaded rod 6 can slide when it rotates, thereby driving the headrest 5 to move, and adjusting the position of the headrest 5, which is suitable for different users and improves comfort.
[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design a structure and implementation method similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
