Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, specifically a shower chair that is easy to adjust in height. Background Technology

[0002] Existing shower chairs are typically of a fixed height and cannot be adjusted to suit user needs, causing inconvenience for users of different heights. Furthermore, the height adjustment mechanisms on some shower chairs are complex and not intuitive, making the adjustment process time-consuming and laborious, thus impacting the user experience.

[0003] Therefore, providing a shower chair that is simple in structure, easy to operate, and has a flexibly adjustable height to meet the different height needs of users is of great practical significance. Summary of the Invention

[0004] The purpose of this invention is to provide a shower chair with an easily adjustable height, which improves ease of use and comfort by optimizing the adjustment mechanism.

[0005] To achieve the above objectives, the present invention provides a height-adjustable shower chair, comprising a seat, a backrest, a support assembly, and an adjustment mechanism. The support assembly is fixedly connected to the seat, and the adjustment mechanism is located within the support assembly, allowing for rapid raising and lowering of the support assembly's height by rotating an adjustment rod or pressing a button.

[0006] Preferably, the support assembly includes an inner tube and an outer tube, the inner tube being connected to the seat and the outer tube being in contact with the ground, and the inner tube sliding within the outer tube via an adjustment mechanism.

[0007] Preferably, the adjusting mechanism includes a threaded connection assembly or a spring-locking structure for quick height adjustment and fixation. The threaded connection assembly includes unidirectional and bidirectional threads with a thread pitch of 1mm to 2mm and a triangular thread profile. The threaded assembly is made of high-strength stainless steel, possessing excellent wear resistance and fatigue resistance, and maintaining stable performance during long-term use. The spring-locking structure has a spring stiffness ranging from 20N / m to 50N / m, a lock length ranging from 10mm to 20mm, and a width ranging from 5mm to 10mm. The spring and lock materials can be selected from high-strength spring steel or wear-resistant engineering plastics to ensure durability and reliability. Experimental test results show that the torque required for rotating the adjusting rod ranges from 0.5Nm to 2Nm, with a height adjustment of 1mm per revolution. Fatigue testing verifies that the adjusting mechanism can be repeatedly adjusted 50,000 times without failure. The rotating adjusting rod is made of high-strength aluminum alloy or stainless steel, with a length ranging from 100mm to 150mm and a diameter ranging from 10mm to 20mm. Experiments show that the rotary adjustment lever can withstand 50,000 rotations without failure. The torque required for user operation is between 1 Nm and 2 Nm, and the height adjustment is 1 mm per rotation, ensuring convenience and accuracy during use.

[0008] Preferably, the rotating adjustment rod cooperates with the threaded connection assembly to precisely adjust the height of the chair seat.

[0009] Preferably, the push button engages with a spring-loaded locking mechanism for quickly releasing or locking the seat height. The push button is made of corrosion-resistant engineering plastic or stainless steel, with a diameter ranging from 20mm to 30mm to ensure easy operation. The operating force range of the push button is 10N to 20N, ergonomically designed for easy one-handed operation. Tested, the push button can withstand 50,000 presses and maintains stability during long-term use.

[0010] Preferably, the seat and backrest are made of antibacterial material to improve hygiene. The antibacterial material may include ABS plastic with added antibacterial agents, a silver ion antibacterial coating, or an antibacterial material certified by ISO 22196. Experimental data shows that this antibacterial material achieves an inhibition rate of over 99.9% against Escherichia coli and Staphylococcus aureus, ensuring a hygienic environment for long-term use. Further experimental verification shows that under high humidity conditions, this antibacterial performance can be stably maintained for more than 2 years, providing a reliable long-term antibacterial effect.

[0011] Preferably, the support assembly is made of aluminum alloy or corrosion-resistant engineering plastic to improve durability and water resistance.

[0012] Preferably, the chair back is provided with ventilation holes to improve comfort during long-term use.

[0013] Preferably, the chair seat has a non-slip surface to improve safety during use.

[0014] Through the above technical solution, the shower chair provided by the present invention achieves rapid and stable adjustment of seat height through structural optimization, thereby improving the user experience. Attached Figure Description
