[0002] A swivel bar stool primarily consists of a base, gas rods, mounting tubes, a bottom plate, and a covering material. These chairs are typically used in front of a bar counter and lack a rolling mechanism. They are typically arranged in a relatively fixed row for orderly use. Furthermore, the chair's swivel function is typically achieved by connecting the gas rods and mounting tubes, providing vertical support and stability, without any retaining structure on the circumference.

[0003] The prior art bar chair, such as the utility model patent document with the authorization announcement number "CN220937398U" and the patent name "A bar chair easy to store", discloses a bar chair, including a bar chair base, a bar chair lifting rod, and a seat cushion.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figure 1 As shown, a bar chair that is easy to disassemble includes a support base 1, a lifting rod 2 and a seat cushion 3. The lifting rod 2 is fixed on the support base 1. A bracket 4 is provided at the bottom of the seat cushion 3. The telescopic end of the lifting rod 2 is rotatably connected to the bracket 4. A bearing is provided on the telescopic end of the lifting rod 2 and the outer ring of the bearing is fixed to the bracket 4.

[0021] like Figure 1 and Figure 2 and Figure 3 As shown, a support plate 6 is provided on the top of the support member 4, and first strip holes 7 are opened on both sides of the support plate 6. Two mounting cavities 8 are opened at the bottom of the seat cushion 3, and a clamping block 9 is fixed in the two mounting cavities 8. A second strip hole 10 is opened on the two clamping blocks 9, and the two second strip holes 10 are respectively opposite to the two first strip holes 7 up and down. Two clamping rods 11 are provided on the support plate 6, and the two clamping rods 11 slide through the first strip hole 7 and the second strip hole 10 in turn and extend into the mounting holes. In the loading cavity 8, a clamping groove 12 is provided on each of the two clamping blocks 9, and the notches of the clamping grooves 12 face the seat cushion 3. A fixing block 25 is fixed on each of the two clamping rods 11. The two fixing blocks 25 are respectively clamped with the two clamping grooves 12. The clamping of the fixing blocks 25 and the clamping grooves 12 and the restriction of the clamping rod 11 by the first strip hole 7 and the second strip hole 10 can prevent the seat cushion 3 from moving horizontally on the support plate 6. A fixing component for fixing the clamping rod 11 is provided on the support plate 6.

[0022] like Figure 1 and Figure 2 and Figure 3As shown, the fixing assembly includes a connecting column 13, a plug-in block 14, a pull rod 15 and an elastic member 16. The connecting column 13 is fixed to the bottom of the support plate 6, the plug-in block 14 is slidably arranged in the connecting column 13, the pull rod 15 is fixed on the plug-in block 14 and the pull rod 15 slides through the connecting column 13 and extends outward, a slot 17 is provided on the clamping rod 11, and the two ends of the elastic member 16 are respectively fixed on the plug-in block 14 and the inner wall of the connecting column 13, the elastic member 16 is used to push the plug-in block 14 to clamp with the slot 17. When the elastic member 16 is in a natural state, the plug-in block 14 is clamped with the clamping rod 11 to limit the up and down movement of the clamping rod 11. By pulling the pull rod 15, the plug-in block 14 can be moved away from the clamping rod 11, thereby releasing the clamping of the plug-in block 14 and the clamping rod 11.

[0023] like Figure 2 and Figure 3 As shown, two limiting columns 18 are fixed on each clamping block 9. The two limiting columns 18 facilitate the clamping rod 11 to be inserted into the clamping groove 12 after rotation. The limiting columns 18 can facilitate the user to rotate the clamping rod 11 so that the fixed block 25 on the clamping rod 11 collides with the limiting columns 18, making it convenient for the user to clamp the fixed block 25 into the clamping groove 12.

[0024] like Figure 4 As shown, an annular slide groove 19 is provided on the top of the bracket 4, and the bottom of the support plate 6 is slidably arranged in the slide groove 19. A plurality of first springs 20 are fixed between the bottom of the slide groove 19 and the bottom of the support plate 6, and a certain buffer can be provided by the first springs 20.

A footrest 22 is fixedly provided on the outer wall of the mounting column 21, and the footrest 22 can be used to facilitate the user to place his feet.

[0026] like Figure 1 As shown, a base 23 is provided at the bottom of the support seat 1, and a bolt 24 is slidably passed through the base 23 and the bolt 24 is threadedly connected to the support seat 1. The base 23 and the support seat 1 can be disassembled through the bolt 24.

[0027] Working principle:

[0028] When the user needs to disassemble the seat cushion 3, the user first pulls the pull rod 15. Pulling the pull rod 15 can move the plug-in block 14 on the pull rod 15 away from the clamping rod 11. Then the user moves the clamping rod 11 upward, and the fixing block 25 on the clamping rod 11 can be disengaged from the clamping groove 12. Then the operator rotates the clamping rod 11. When the fixing block 25 on the clamping rod 11 coincides with the first strip hole 7 and the second strip hole 10, the user can directly pull the clamping rod 11 to withdraw the clamping rod 11 from the first strip hole 7 and the second strip hole 10, and then the user can remove the seat cushion 3 from the support plate 6.
