Description

Technical Field

[0001] This utility model belongs to the field of bar stool technology, specifically relating to a folding portable bar stool. Background Technology

[0002] There are many types of bar stools, but their basic structure consists of an upper seat, middle legs, and a lower base. Heating is typically pneumatically driven, with the lifting mechanism using piston movement to adjust the stool's height. This mechanism generally uses an outer tube and a cylinder. For example, the bar stool in patent publication number CN2857645Y has a footrest located at the bottom of the lifting tube. When the user adjusts the seat height, the footrest rises or falls along with the seat, and the distance between the seat and footrest remains constant. This prevents the user's feet from dangling due to the seat being raised too high. However, this type of bar stool has a fixed shape, making it inconvenient to fold and store. Furthermore, frequent height adjustments via the lifting mechanism can cause gas in the cylinder to escape from a weak friction point, potentially leading to an explosion and reducing the safety of the bar stool.

[0057] Example 1:

[0058] The following is combined with Figures 1-3 This utility model will be described in detail.

[0059] A folding portable bar stool includes a seat 1, an adjustment rod 2, a cylinder 3, an outer tube 4, a base 5, and a support frame 6, and also includes a mounting sleeve 7, which is threaded to the outside of the outer tube 4; a plurality of ball bearings 8 are rotatably disposed on the inner wall of the mounting sleeve 7; wherein, the cylinder 3 is movably disposed inside the outer tube 4 and rolls against the ball bearings 8.

[0060] Furthermore, it also includes a pneumatic switch 11, which is movably located inside the top of the cylinder 3 and works in conjunction with the adjusting rod 2; a piston 12, which is movably located inside the cylinder 3; and a movable rod 13, whose top end is fixed to the piston 12 and whose bottom end movably passes through the cylinder 3 and is fixed to the outer sleeve 4.

[0061] Furthermore, it also includes a threaded cylinder 22, which is fixed to the bottom outer side of the outer sleeve 4; wherein the threaded cylinder 22 is threadedly connected to the base 5 through an externally provided thread; and an elastic sheet 23, which is fixed to the bottom surface of the outer sleeve 4 and abuts against the inner wall of the base 5.

[0062] Furthermore, it also includes a mounting hole 24, which is located at the center of the mounting sleeve 7; wherein the ball bearing 8 is rotatably mounted on the inner wall of the mounting hole 24; a mounting groove 25, which is located at the bottom center of the mounting sleeve 7 and communicates with the mounting hole 24; and an internal thread 26, which is located on the inner wall of the mounting groove 25; wherein the mounting sleeve 7 is threadedly fixedly connected to the outer sleeve 4 through the internal thread 26.

[0063] A support frame 6 is fixedly installed on the outer periphery of the base 5, which provides stable support for the bar stool.

[0064] The base 5 has a threaded hole at the top, and a threaded cylinder 22 is fixedly installed at the bottom of the outer sleeve 4. The outer sleeve 4 and the base 5 are fixedly connected by the engagement of the thread on the outer wall of the threaded cylinder 22 with the threaded hole.

[0065] An elastic sheet 23 is fixedly installed on the bottom surface of the outer tube 4. When the outer tube 4 is fixedly connected to the base 5, the elastic sheet 23 is squeezed and deformed. At the same time, the elastic deformation of the spring 184 pushes the outer tube 4 to a tight contact with the base 5, further improving the stability of the connection between the outer tube and the base 5.

[0066] The bottom of cylinder 3 is movably installed inside the outer sleeve 4, and piston 12 is movably installed inside cylinder 3. A movable rod 13 is fixedly connected to the bottom surface of piston 12. The bottom end of movable rod 13 movably passes through cylinder 3 and is fixedly installed on outer sleeve 4. The top of cylinder 3 is fixedly connected to the bottom surface of seat 1. An adjusting rod 2 is movably installed at the bottom of seat 1. At the same time, a pneumatic switch 11 is movably installed inside the top of cylinder 3. The pneumatic switch 11 can be activated by adjusting rod 2.

[0067] The outer top of the outer sleeve 4 is provided with an external thread; the center of the mounting sleeve 7 is provided with a mounting hole 24, through which the cylinder 3 is movably installed; at the same time, the center of the bottom of the mounting sleeve 7 is provided with a mounting groove 25, through which the bottom of the mounting groove 25 is movably fitted onto the top of the outer sleeve 4; and since the inner wall of the mounting groove 25 is provided with an internal thread 26, the mounting sleeve 7 is fixedly installed on the outside of the outer sleeve 4 through the meshing connection between the internal thread 26 and the external thread.

[0068] Several balls 8 are rotatably mounted on the inner wall of the mounting hole 24. When the cylinder 3 is installed, the balls 8 roll into contact with the outer wall of the cylinder 3, thereby replacing the original sliding friction with the rolling friction of the balls 8. This reduces the friction experienced by the cylinder 3 during operation and prevents the outer wall of the cylinder 3 from becoming thin after repeated friction, which could lead to an explosion of gas inside the cylinder 3 and cause injury to the user.

[0069] Example 2:

[0070] The following is combined with Figures 1-6 This utility model will be described in detail.

[0071] A folding portable bar stool also includes a support frame 6 comprising a connecting rod 61 and a leg 62, the connecting rod 61 and the leg 62 being rotatably connected; a chuck 9, which is fixedly sleeved on the bottom of the base 5; and a snap-fit ​​10, which is retractably disposed in the chuck 9 and used to limit the leg 62.

[0074] Furthermore, it also includes a rotating groove 19, which is located within the movable end of the connecting rod 61; wherein the rotating groove 19 has openings on the side facing the bracket and the lower side; a rotating rod 20, which is fixedly mounted within the rotating groove 19; and a fixing block 21, which is fixedly mounted on the end face of the support leg 62 and rotatably mounted outside the rotating rod 20.

[0075] The support frame 6 includes connecting rods 61 and legs 62. There are several connecting rods 61 and legs 62, and the number of them is equal.

[0076] The top end of the connecting rod 61 is fixedly installed on the outer periphery of the base 5. At the same time, a rotating groove 19 is provided in the top of the connecting rod 61. A mounting block is fixedly installed on the top of the support leg 62, and a rotating rod 20 is fixedly installed in the rotating groove 19. The mounting block is rotatably installed outside the rotating rod 20. The rotating groove 19 has openings on the side facing the support leg 62 and the side facing the ground, which allows the support leg 62 to rotate 90° around the rotating rod 20. The top of the rotating groove 19 can limit the rotation of the support leg 62 to prevent the support leg 62 from failing to support the bar stool when it is in use.

[0077] A chuck 9 is fixedly installed on the bottom of the base 5. The periphery of the chuck is provided with a number of equal slots 14 for the support legs 62. Sliding grooves 15 are provided on both sides of the inner wall of the slots 14. Limiting grooves 181 are provided on both sides of the inner wall of the sliding grooves 15. A fixed rod 182 is fixedly installed in the limiting groove 181. The two ends of the sliding rod 183 are slidably installed on the fixed rods 182 on both sides. A spring 184 is sleeved on the fixed rod 182. The two ends of the spring 184 are fixedly connected to the inner wall of the limiting groove 181 and the sliding rod 183, which can realize the reset of the sliding rod 183. A locking rod 16 is fixedly sleeved on the outside of the sliding rod 183. The bottom end of the locking rod 16 extends into the slot 14.

[0078] The support leg 62 has locking holes 17 on both sides. When the support frame 6 is folded and stored, the support leg 62 can be rotated 90° to place it in the locking slot 14. At the same time, during the rotation of the support frame, the locking rods 16 on both sides are pushed to slide into the sliding groove 15. At the same time, the spring 184 deforms and then returns to its original shape, pushing the locking rods 16 to engage with the locking holes 17 to fix the support leg 62. When using the support leg 62, the locking rods 16 can be pushed out of the locking holes 17, thereby enabling the rotation of the support leg 62 and supporting the bar stool.
