Abstract
This utility model provides a table with adjustable height, easy activation, and rigid locking. It includes a tabletop and a table frame. The tabletop is supported and locked onto the table frame by a rigid lockable gas spring. The rigid lockable gas spring has a movable end for supporting and connecting the tabletop and a fixed part for supporting and connecting to the table frame. The rigid lockable gas spring is also connected to an adjustment device for positioning and lifting the movable end. By pressing the adjustment device, the rigid lockable gas spring can lower the tabletop with a light press on the activation rod, and by lifting the tabletop lightly by hand, it can stop at the desired position. The special rigid lockable gas spring allows the tabletop to perform stepless vertical adjustments with the guiding tube, easily operated by one person, avoiding the hassle of using pins.

Description
A Table with Adjustable Height, Easy Activation, and Rigid Locking

Technical Field This utility model relates to the field of tables, specifically to a table with adjustable height, easy activation, and rigid locking using a rigid lockable gas spring.

Background Technology Tables are indispensable items in everyday life. Traditional tables consist of four wooden legs supporting a tabletop, a style that has been commonly used for generations. However, the height of the table should match the height of the user to avoid spinal health issues, especially for growing students. Incorrect table height can lead to problems such as myopia and hunchback. To address this, height-adjustable study desks have been developed, typically using iron frames with adjustable upper and lower sections that align holes for height adjustment using pins. However, this method is cumbersome, often requires two people to adjust, and can be impractical if pins are lost.

Summary of the Invention The main objective of this utility model is to provide a table that allows for easy single-handed height adjustment, with an aesthetically pleasing design suitable for users to freely adjust the tabletop height.

This utility model includes a tabletop and a table frame. The tabletop is supported and locked onto the frame by a rigid lockable gas spring, which has a movable end for supporting and connecting the tabletop and a fixed part for supporting and connecting to the frame. The rigid lockable gas spring is also connected to an adjustment device for positioning and lifting the movable end vertically.

The tabletop is equipped with a fixed frame connecting to the movable end, which includes a bracket and a guiding tube. The bracket is disk-shaped for contacting and fixing the tabletop. Inside the guiding tube, a positioning block is provided for the movable end to interlock. The movable end is fixed to the positioning block with a nut.

The table frame includes a positioning sleeve for mounting the fixed part, a computer case stand, a sliding keyboard tray, and a tabletop with pen and cup holders.

Advantages of the Utility Model The rigid lockable gas spring allows for vertical height adjustments with minimal effort by pressing the adjustment device, enabling the user to raise or lower the tabletop easily. The elastic principle of the gas spring facilitates stepless height adjustment, simplifying single-person operation and avoiding the complications of using pins.

Detailed Implementation As shown in Figures 1 and 2, the utility model includes a tabletop 2 and a table frame 3. The tabletop 2 is supported by a rigid lockable gas spring 1, powered by nitrogen and using liquid oil as a locking medium. The rigid lockable gas spring 1 has a movable end 11 for the tabletop and a fixed part 12 for the frame. It is also connected to an adjustment device 13 for positioning the movable end 11. The tabletop 2 may include additional features like a sliding keyboard tray 21, pen holders 22, and cup holders 23.

Detailed connections of the rigid lockable gas spring 1 and other components are shown in Figures 2 and 3. The movable end 11 is connected to the fixed frame 14, which includes a disk-shaped bracket 144 for tabletop contact and a guiding tube 145. The guiding tube 145 is mounted on the gas spring 1, and the movable end 11 is fixed in place using a positioning block 142 and a nut 143.

As shown in Figures 1 and 4, the table frame 3 has a positioning sleeve 31 for fixing the gas spring 1, a stand 32 for a computer case, a sliding keyboard tray 21, and storage compartments 24. The adjustment device 13 can be a button or lever, placed conveniently on the table.

The model can be scaled for different users, with larger sizes for adults and smaller sizes for children. Adjusting the tabletop 2 is easy with minimal force using the adjustment device 13 for lowering, and lifting the tabletop by hand for raising. The elastic principle of the gas spring allows for smooth height adjustments, making single-person operation straightforward and eliminating the need for pins.

The movable end 11 is not limited to connecting the tabletop 2. It can also refer to other components, such as extending rods 111 fixed to the positioning sleeve 31 on the table frame 3, within the protection scope of this utility model.
