DETAILED DESCRIPTION
[0020] In this specification, the orientation terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or possibly mentioned are defined with respect to its structure, and they are relative concepts. Therefore, it is possible to change accordingly according to its different positions, different use states; therefore, these or other orientation terms should not be interpreted as restrictive terms.
[0021] As used in this specification and claims, the singular forms“a,”“an” and“the” include plural referents unless the context clearly dictates otherwise. It should also be understood that the term“and / or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
[0022] In order to make the technical problems, technical schemes and beneficial effects to be solved in the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present application and not used to limit the present application.
[0023] The utility model provides a kind of adjustable bar chair as shown in the accompanying drawings Figures 1-4 As shown in the accompanying drawings, the adjustable bar chair includes a seat cushion 1 and an adjusting support mechanism located at the bottom of the seat cushion 1. The seat cushion 1 is integrally connected with a backrest 12. The adjusting support mechanism includes an upper fixed block 2 and a lower fixed block 3. A plurality of support legs 4 are fixedly connected to the outer sides of the upper fixed block 2 and the lower fixed block 3. In the utility model, the number of support legs 4 is three and they are evenly distributed on the outer sides of the upper fixed block 2 and the lower fixed block 3. The support legs 4 are connected to the upper fixed block 2 and the lower fixed block 3 through first bolts 13. The upper fixed block 2 and the lower fixed block 3 are fixedly connected with an outer shell 5 on one side. The outer shell 5 is rotatably connected with a worm 6 and a spur gear 7 that is engaged with the worm 6. One end of the worm 6 is fixedly connected with a crank 8. The spur gear 7 is engaged with a support rack 9 on one side, and the support rack 9 penetrates through the upper fixed block 2 and the lower fixed block 3. A circular plate 10 is fixedly connected to the bottom of the seat cushion 1. The circular plate 10 is connected to the seat cushion 1 through a plurality of screws 19. The top of the support rack 9 is rotatably connected to the circular plate 10 through a first bearing 11.
[0024] As shown in the accompanying drawings Figure 2 and Figure 4 In the utility model, the outer shell 5 is connected to the upper fixed block 2 and the lower fixed block 3 through a second bolt 14. The worm 6 is rotatably connected to the outer shell 5 through a second bearing 15. A rotating shaft 16 is fixedly arranged on the spur gear 7, and the two ends of the rotating shaft 16 are rotatably connected to the outer shell 5 through third bearings 17, which improves the stability during transmission. A rubber sleeve 18 is sleeved on the crank 8, which improves the comfort and hand feeling of operation.
[0025] Working principle: in the specific implementation of the utility model, the user rotates the crank 8, and the worm 6 rotates accordingly. Since the worm 6 is engaged with the spur gear 7, the spur gear 7 will also rotate correspondingly. The rotation of the spur gear 7 drives the support rack 9 to move along its length direction. Since the support rack 9 is connected to the circular plate 10 through the first bearing 11, the circular plate 10 and the seat cushion 1 can slide up and down along the support legs 4, thereby realizing the adjustment of the height of the bar chair.
