Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example:

[0025] Reference Figures 1-4 This application discloses an anti-tipping rotating bar chair, comprising a base 1, a support rod 2, and a seat 3. The support rod 2 is vertically mounted on the base 1, and the seat 3 is rotatably connected to the end of the support rod 2 away from the base 1. This connection method can be achieved through bearings and is a common existing technology. The seat 3 is provided with a cushion 19 to increase the comfort of the person sitting on it. The side of the base 1 away from the support rod 2 is fixed to an anti-slip pad 20, which can be made of rubber to increase the friction between the base 1 and the supporting surface.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a number of supporting components are rotatably mounted on the base 1. These components include a rotating shaft 5, a support frame 6, and a support rod 7. A storage groove 8 is provided on the base 1. The rotating shaft 5 is rotatably positioned within the storage groove 8. The support frame 6 is fixed to the rotating shaft 5. The support rod 7 is fixed to the support frame 6 and located at the end of the support frame 6 opposite to the rotating shaft 5. A torsion spring 9 is sleeved on the rotating shaft 5. One end of the torsion spring 9 is fixed to the side wall of the storage groove 8, and the other end is fixed to the support frame 6. The torsion spring 9 is used to make the support rod 7 contact the ground outside the base 1. The torsion spring 9 causes the support frame 6 to drive the support rod 7 to contact the ground or other fixed objects outside the base 1 around the rotating shaft 5, increasing the support area of ​​the base 1 and improving the stability when people are riding on it. A limiting rod 10 is rotatably installed inside the storage slot 8, and a limiting block 11 is fixed on the limiting rod 10. The limiting block 11 is used to abut against the support rod 7 when it is located inside the storage slot 8. A bolt 13 is provided on the limiting rod 10, and the bolt 13 passes through the limiting rod 10 and is threadedly connected to the base 1. By rotating the limiting rod 10 and the limiting block 11, the supporting rod 7 can be effectively limited after it rotates along the pivot 5 into the storage slot 8. By screwing in the bolt 13, the limiting rod 10 is prevented from rotating. This makes it convenient for the bar stool to be used in situations where the space is small or the support rod 7 is not needed. A rubber sleeve 12 is fitted on the support rod 7 to improve friction.

[0027] like Figure 1 and Figure 4As shown, an adjustable foot support 4 is provided on the side wall of the support rod 2. Several vertically oriented limiting grooves 14 are provided on the side wall of the support rod 2. A fixing sleeve 15 is slidably fitted onto the support rod 2. The foot support 4 is fixed to one side of the fixing sleeve 15. A countersunk hole 16 corresponding to one of the limiting grooves 14 is provided on the fixing sleeve 15. A pin 17 passes through the countersunk hole 16. A spring 18 is fitted on a section of the pin 17 within the countersunk hole 16. One end of the spring 18 is fixedly connected to the pin 17, and the other end is fixedly connected to the side wall of the countersunk hole 16. This allows for effective height adjustment and fixation of the foot support 4 by the contact between the pin 17 and different limiting grooves 14.

[0028] Working principle:

[0029] When using the chair, first adjust the height of the footrest 4 on the support rod 2 according to the height of the person so that it can effectively support the person's feet when sitting. When it is necessary to increase the stability of the bar chair, turn the screw 13 and rotate the limit rod 10 so that the limit rod 10 drives the limit block 11 to release the limit on the support rod 7. At this time, the support frame 6 will rotate the support rod 7 outward from the storage groove 8 due to the torsion spring 9 and abut against the ground or fixed object outside the base 1, increasing the support stability of the base 1 and effectively preventing the bar chair from tipping over.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
