[0033] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0034] like Figures 1 to 4 The lifting table includes a plurality of lifting wheels 3, a plurality of lifting wheels 3 and a plurality of lifting wheels 3, 4 and a plurality of lifting wheels 3. The lifting wheel 3 is rotatably installed in the mounting groove, and the lower side protrudes from the lower side of the base 4; the lower end of the air column 5 is installed on the upper side of one end of the base 4, and the upper end of the air column 5 is provided with a pressing head 51, and is installed on the lower side of one end of the desktop plate 6, and the base 4 and the desktop plate 6 have the same direction as the free end; the release switch includes a rotating shaft 7 and a rotating rod 8, the rotating shaft 7 is connected to the lower side of the desktop plate 6 in parallel and rotationally, one end of the rotating rod 8 is fixedly connected to the rotating shaft 7, and the other end of the rotating rod 8 is horizontally against the upper side of the pressing head 51 at the upper end of the air column 5, and the rotating rod 8 rotates downward around the rotating shaft 7 to press the pressing head 51 to control the extension and retraction of the air column 5; the lifting table also includes an elastic gasket 9 installed on the lower side of the desktop plate 6, and the upper side of the rotating rod 8 is against the elastic gasket 9.

[0035] Through the above arrangement, first, the roller 3 facilitates the movement of the lifting table and facilitates the insertion of the base 4 under the bed; second, the upper side of the roller 3 is hidden in the installation groove to lower the height of the base 4, making it convenient to insert the base 4 under the bed with a small gap; third, the upper and lower sides of the rotating rod 8 are respectively against the elastic gasket 9 and the pressing head 51, reducing the shaking of the rotating rod 8, and the lifting table makes less noise when moving.

[0036] The upper and lower surfaces of the base 4 of the present application are both horizontal. Specifically, the thickness of the base 4 is less than or equal to 3 cm, and the height of the lower side of the roller 3 protruding from the base 4 is less than or equal to 5 mm. The height difference from the upper side of the base 4 to the ground is minimized as much as possible so that the base 4 can be inserted under the bed; the release switch and the air column 5 can refer to the existing lifting table. By releasing the switch and pressing the pressing head 51, the length of the air column 5 can be adjusted, and then the height of the desktop panel 6 can be adjusted; specifically, the rotating shaft 7 rotates, driving the rotating rod 8 to rotate downward around the axis of the rotating shaft 7, the rotating rod 8 disengages from the elastic gasket 9, and presses down the pressing head 51 to adjust the height of the desktop panel 6; after releasing the pressing head 51, the pressing head 51 rebounds, and the rotating rod 8 rotates upward around the axis of the rotating shaft 7 and re-aligns with the elastic gasket 9.

[0037] As an implementation method, the base 4 includes two support beams 41 and a connecting rod 42. The two support beams 41 are arranged parallel to each other, and the connecting rod 42 is vertically fixedly connected between the support beams 41. The base 4 has an I-shaped structure, and mounting grooves are provided on the lower sides of both ends of the support beams 41. The lower end of the air column 5 is installed on the upper side of one end of the connecting rod 42.

[0038] Through the above arrangement, the base 4 has a simple structure and is light in weight, which further facilitates the movement of the lifting table.

[0039] The length of the support beam 41 of the present application is basically consistent with the width of the desktop panel 6, and the length of the connecting rod 42 is basically consistent with the length of the desktop panel 6. The two ends of the connecting rod 42 can be fixed together by welding or fasteners, so that the entire desktop panel 6 has better stability.

[0040] As an implementation method, rounded corners 43 are provided on the upper sides of both ends of the support beam 41 .

[0041] With the above arrangement, the support beam 41 is less likely to scratch the bed.

[0042] As an implementation method, the lifting table also includes a telescopic component, which includes an outer tube 10 and an inner tube 11. The lower end of the outer tube 10 is fixedly connected to the upper side of the base 4, the upper end of the inner tube 11 is fixedly connected to the lower side of the desktop panel 6, and the lower end of the inner tube 11 is slidably connected to the upper end of the outer tube 10. The air column 5 is arranged in the telescopic component.

[0043] Through the above arrangement, the stability of the table top 6 and the air column 5 is increased.

[0044] The telescopic assembly of the present application can only be extended and retracted axially, and the upper and lower ends can withstand bending moments to reduce the force on the gas column 5 and improve the stability of the gas column 5.

[0045] As an implementation method, the telescopic assembly also includes two reinforcing beams 12 parallel to the connecting rod 42, and a reinforcing plate 13 fixedly connected between the reinforcing beams 12. The reinforcing beams 12 are fixedly connected to the lower side of the desktop panel 6. The rotating shaft 7 is arranged between the two reinforcing beams 12. The air column 5 passes through the reinforcing plate 13, and the pressing head 51 of the air column 5 is arranged on the upper side of the reinforcing plate 13.

[0046] Through the above configuration, the stability of the desktop panel 6 is further improved.

[0047] As an implementation method, the outer tube 10, the inner tube 11 and the reinforcement beam 12 are all configured as square steel tubes.

[0048] Through the above arrangement, the weight of the lifting table is reduced while ensuring the stability of the lifting table.

[0049] As an implementation method, the release switch further includes a dial plate 14 , and one end of the rotating shaft 7 away from the rotating rod 8 extends to the lower side of the edge of the desktop panel 6 and is installed with the dial plate 14 .

[0050] With the above arrangement, the height of the desktop panel 6 can be adjusted by manually turning the dial plate 14 to rotate the shaft 7 .

[0051] In another embodiment, Figures 5 to 9 As shown, the lifting table also includes a pressure plate 15 arranged parallel to the base 4. One end of the pressure plate 15 is fixedly connected to a sliding sleeve 16. The other end of the pressure plate 15 is oriented in the same direction as the free end of the base 4. The sliding sleeve 16 is slidably connected to the outer tube 10. The outer tube 10 and the sliding sleeve 16 are connected by an elastic member 17.

[0052] Through the above arrangement, the sliding of the base 4 under the bed can be reduced, and the lifting table is not prone to displacement during use.

[0053] The pressing plate 15 of the present application is slidably connected to the outer cylinder 10 through the sliding sleeve 16. In the initial state, the pressing plate 15 is located at the lower end of the outer cylinder 10, and there is a gap of 5-10 cm between the lower side of the pressing plate 15 and the base 4, and the elastic force of the elastic member 17 is basically zero; when the base 4 needs to be inserted under the bed, the pressing plate 15 is manually pressed down first, and the pressing plate 15 is pressed downwardly on the upper side of the base 4. The elastic member 17 is deformed to generate elastic force. When both the pressing plate 15 and the base 4 are inserted under the bed, release your hand, and the elastic member 17 drives the pressing plate 15 to move upward and press it tightly on the lower side of the bed. Under the action of the friction between the pressing plate 15 and the bed, the base 4 is not easy to slide. When the user on the bed uses the desktop panel 6, the base 4 is not easy to slide.

[0054] As an implementation method, a guide groove 18 extending vertically is provided on the outer tube 10, and the sliding sleeve 16 is fixedly connected to a fixed key 19. The fixed key 19 passes through the guide groove 18 and extends into the outer tube 10. The elastic member 17 is configured as a tension spring, the upper end of the tension spring is connected to the outer tube 10, and the lower end of the tension spring is connected to the fixed key 19.

[0055] When the sliding sleeve 16 of the present application slides along the outer cylinder 10, the fixed key 19 moves in the guide groove 18, and the sliding sleeve 16 stretches the tension spring through the fixed key 19. When the sliding sleeve 16 slides downward, the tension spring stretches. After releasing the hand, the tension spring rebounds, causing the pressure plate 15 to reset.

[0056] As an implementation method, a foot pedal 20 is fixedly connected to a side of the sliding sleeve 16 away from the pressing plate 15 .

[0057] Through the above arrangement, it is convenient to step on the foot pedal 20 to control the up and down movement of the pressing plate 15.

[0058] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
