The table board assembly comprises a hollow table board, the inner wall of the hollow table board is sleeved with an inner core table board, and the hollow table board is connected to a hose.

The rack is connected to the bottom of the hollow table top, a sliding groove is provided on one side of the rack, the rack is clamped with the sliding sleeve through the sliding groove, and one side of the gear is meshed with the rack. The meshing of the gear and the rack improves the stability of the lifting of the table top assembly, and the clamping of the sliding sleeve and the rack ensures the meshing transmission of the gear and the rack.

A groove is provided on the inner wall of the ferrule away from the rotating shaft, a block is provided on the end of the rotating shaft close to the ferrule, and one end of the rotating shaft is fixedly connected to the sliding sleeve. When adjusting the extension length of the hollow table board, the hollow table board is quickly pulled out to reduce the air pressure on the inner wall of the ferrule, so that the ferrule moves toward the rotating shaft, so that the block on the rotating shaft engages with the groove, restricting the rotation of the gear on one side of the ferrule, fixing the position of the hollow table board for safety protection.

The center of the gear is provided with a through hole, one side of the ferrule is clamped with the sleeve through a bearing, the side of the ferrule away from the sleeve is connected with an electric valve, the through hole in the center of the gear is clamped with the rotating shaft through a sealing ring, and a first air chamber is formed between the inner wall of the ferrule and the rotating shaft. The air pressure of the first air chamber is controlled by the electric valve, and when the air pressure inside the first air chamber is too high, the pressure is released through the electric valve, and when the air pressure in the first air chamber suddenly increases, the electric valve is controlled to open, and the air pressure in the first air chamber is slowly released, so as to ensure that the hollow table top is slowly retracted after being compressed, thereby reducing damage to the user.

A scraper is provided on one side of the hollow table board close to the inner core table board, and the scraper fits the inner core table board. A second air chamber is formed between the hollow table board and the inner core table board, and the hose connects the first air chamber to the second air chamber.

Compared with the prior art, the beneficial effects achieved by the utility model are:

1. The safety of the device is improved by setting the positioning module and the table top assembly, and the life safety of the user is guaranteed. When the hollow table top is hit, the air pressure inside the hollow table top increases, and the air pressure is transmitted to the ferrule through the hose, and then the pressure is slowly released through the electric air valve. At the same time, the air pressure pushes the ferrule to move laterally, driving the gear to disengage from the meshing with the rack, so that the device can quickly buffer the impact and avoid the hollow table top from causing a hard collision to the user.

2. Through the positioning module, supporting table legs and table board components, the user can adjust the horizontal position of the hollow table board according to needs. The engagement of the gear and the rack ensures the stable withdrawal of the hollow table board. At the same time, by controlling the internal air pressure of the hollow table board, the sudden retraction of the hollow table board is avoided, thereby improving the user's comfort and the applicability of the device.

3. Through the arrangement of the footboard assembly, supporting table legs, positioning module and table top assembly, the user can quickly adjust the height of the device. At the same time, through the electrical connection between the positioning module and the footboard assembly, the electric air valve in the positioning module detects whether the table top assembly is hit during the rising process.

By starting the motor, the motor drives the screw rod 103 to rotate inside the slide rail 102, and the screw rod 103 drives the slider 104 to slide along the upper surface of the slide rail 102 to adjust the height of the table board assembly 4, thereby improving the degree of automation of the device.

There are two groups of support legs 2, which are symmetrically distributed on both sides of the table board assembly 4. There are two support legs 2, which are hinged to each other at the center point, and a frame rod is horizontally arranged at the hinge position of the support legs 2. This frees up the user's foot space, facilitates the user's use and activities, and at the same time improves the stability of the device, reduces the shaking of the device, and further improves the safety of the device.

The rack 302 is connected to the bottom of the hollow table top 401, and a sliding groove is provided on one side of the rack 302. The rack 302 is engaged with the sliding sleeve 301 through the sliding groove, and one side of the gear 303 is meshed with the rack 302. The meshing of the gear 303 and the rack 302 improves the stability of the lifting of the table top assembly 4, and the engagement of the sliding sleeve 301 and the rack 302 ensures the meshing transmission of the gear 303 and the rack 302.

A groove is provided on the inner wall of the sleeve 305 away from the rotating shaft 306, and a block 307 is provided on the end of the rotating shaft 306 close to the sleeve 305. One end of the rotating shaft 306 is fixedly connected to the sliding sleeve. When adjusting the extension length of the hollow table board 401, the hollow table board 401 is quickly pulled out, so that the air pressure on the inner wall of the sleeve 305 is reduced, so that the sleeve 305 moves toward the rotating shaft 306, so that the block 307 on the rotating shaft 306 is engaged with the groove, limiting the rotation of the gear 303 on one side of the sleeve 305, fixing the position of the hollow table board 401, and performing safety protection.

When the air pressure in the first air chamber suddenly increases, the electric valve is controlled to open, and the air pressure in the first air chamber is slowly released, so as to ensure that the hollow table top 401 is slowly retracted after being compressed, thereby reducing damage to the user.

A scraper 403 is provided on one side of the hollow table board 401 close to the inner core table board 402. The scraper 403 fits the inner core table board 402. A second air chamber is formed between the hollow table board 401 and the inner core table board 402. The hose 304 connects the first air chamber with the second air chamber. When the user accidentally hits the hollow table board 401, the hollow table board 401 moves horizontally toward the inner core table board 402, causing the air pressure in the second air chamber to increase, and then the air pressure is transmitted to the first air chamber through the hose 304, and then the pressure is released through the electric air valve. At the same time, the air pressure pushes the ferrule 305 to move horizontally, driving the gear 303 to disengage from the meshing with the rack 302, so as to quickly buffer the impact and avoid hard collisions to the user.

There are two hollow table boards 401, which are symmetrically distributed on both sides of the inner core table board 402. Limit blocks are set on both sides of the inner core table board 402, and the limit blocks are clamped with the scraper 403. There are two scrapers 403. By pulling out the hollow table board 401, the hollow table board 401 is adjusted to a size suitable for the user's operation, which improves the user's comfort. The limit blocks prevent the hollow table board 401 from falling. When pulling out, the scraper 403 cleans the surface of the inner core table board 402, which improves the airtightness inside the hollow table board 401 and improves the safety of the device.

The working principle of this utility model:

First, by starting the motor, the motor drives the screw rod 103 to rotate inside the slide rail 102, and the screw rod 103 drives the slider 104 to slide along the upper surface of the slide rail 102, and the distance between the two sliders 104 on the screw rod 103 is adjusted to drive the support leg 2 to deflect and adjust the height of the table board assembly 4;

Then, at the top of the supporting table leg 2, the hollow table top 401 is pulled out to adjust the hollow table top 401 to a size suitable for the user to operate, thereby improving the user's comfort. The hollow table top 401 is prevented from falling off by the limit block. The surface of the inner core table top 402 is cleaned by the scraper 403 while being pulled out, thereby improving the air tightness inside the hollow table top 401 and preventing the hollow table top 401 from being suddenly retracted.

While the hollow table top 401 is being pulled out, the electric air valve on one side of the ferrule 305 is opened to control the air pressure balance inside the hollow table top 401;

When adjusting the extension length of the hollow table top 401, the hollow table top 401 is quickly pulled out, so that the air pressure on the inner wall of the ferrule 305 is reduced, so that the ferrule 305 moves toward the rotating shaft 306, so that the block 307 on the rotating shaft 306 is engaged with the groove, limiting the rotation of the gear 303 on one side of the ferrule 305, fixing the position of the hollow table top 401 for safety protection;

When the hollow table top 401 is hit, a first air chamber is formed between the inner wall of the sleeve 305 and the rotating shaft 306, and a second air chamber is formed between the hollow table top 401 and the inner core table top 402. The hose 304 connects the first air chamber with the second air chamber, and the hollow table top 401 moves horizontally toward the inner core table top 402, so that the air pressure in the second air chamber increases, and then the air pressure is transmitted to the first air chamber through the hose 304, and then the pressure is released through the electric air valve. At the same time, the air pressure pushes the sleeve 305 to move horizontally, driving the gear 303 to disengage from the meshing with the rack 302, reducing the obstruction of the gear 303 to the movement of the hollow table top 401, facilitating rapid buffering of the impact, avoiding the hard collision of the hollow table top 401 on the user, and improving the safety of the device;

When raising or lowering the height of the table top assembly, through the electrical connection between the positioning module 3 and the foot board assembly 1, the electric air valve in the positioning module 3 detects whether the table top assembly 4 is hit during the rising process. When the air pressure changes rapidly during the process of raising or lowering the table top assembly 4, the motor at one end of the control screw 103 is controlled to rotate in the opposite direction for adjustment, thereby improving the degree of automation of the device and further improving the safety of the device.
