Description

Technical Field

[0001] This utility model belongs to the technical field of fitness equipment and relates to an adjustable stool with an anti-shaking cushion. Background Technology

[0002] Adjustable benches typically feature a soft, upholstered surface for a comfortable reclining experience. The seat and back cushions are also ergonomically designed to ensure user comfort even during extended use. These benches usually offer multiple adjustment functions, allowing users to customize the angle and height for targeted muscle training. Currently, the seat cushions of adjustable stools can move back and forth during adjustment, but they all use linear bearing structures. When the linear bearing structure is under load, it will produce elastic deformation due to insufficient rigidity, resulting in poor movement accuracy and obvious shaking, which affects the accuracy of adjustment.

The linear guide rail is fitted with a linear slider. The linear slider is connected to a seat cushion mounting plate by a third fastening screw. The seat cushion mounting plate is connected to the seat cushion by a second fastening screw. A backrest is connected to the top of the backrest mounting bracket. A cross plate is hinged between the front and rear adjustment plate and the backrest mounting bracket. A support tube is connected to the left side of the cross plate and a support tube is connected to the right side of the cross plate.

[0005] In a preferred embodiment of this utility model: the edge of the seat cushion mounting steel plate is connected to a positioning plate, and the positioning plate is equipped with a positioning pin by means of a threaded fitting. The positioning pin is inserted into the positioning hole opened in the front and rear adjustment plate, and the slide rail mounting base is installed on the front and rear adjustment plate by means of a washer and a fastening screw.

[0006] In a preferred embodiment of this utility model: the bottom of the front and rear adjustment plates is connected to a seat angle adjustment plate, and multiple through holes in the seat angle adjustment plate are fitted with pull pins, which are installed on the support tube.

[0007] In a preferred embodiment of this utility model: the second support tube is connected to a multi-toothed plate, and the multi-toothed plate has multiple toothed grooves for mounting pins. The pins are installed on the rear support, and the rear support is hinged to the bottom of the cushion mounting frame.

[0008] In a preferred embodiment of this utility model, a support pipe three is connected to the bottom of the support pipe two, and casters are installed on the support pipe three.

[0009] As a preferred embodiment of this utility model: a handle seat is installed at the bottom of the support tube.

[0010] The beneficial effects of this utility model are: This utility model discloses an adjustable stool with an anti-shaking cushion. A linear guide rail is equipped with a linear slider. The linear slider is connected to the seat mounting plate via three fastening screws. The seat mounting plate is connected to the seat via two fastening screws, allowing the seat and the linear slider to move smoothly on the linear guide rail. The frictional resistance is low, and the difference between dynamic and static frictional resistance is small, enabling high-precision positioning. It can withstand forces and torque loads in different directions, eliminating swaying. It is suitable for stable operation under high load conditions and facilitates the forward and backward movement of the adjustable stool's cushion, making it convenient and reliable.
