[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] This embodiment discloses a pneumatic lifting table, such as Figures 1 to 6 As shown, the utility model has the effect of facilitating the adjustment of the height of the table, including a desktop; the bottom of the desktop is fixedly connected to a lifting bracket and a support frame; the support frame includes a plurality of movable frames that cooperate with each other, and the lifting bracket drives the desktop to rise and fall or drives the movable frame of the support frame to open and close by setting a control mechanism.

[0022] The bottom of the desktop is fixedly connected to the lifting bracket, and the lifting bracket is fixedly connected to the support frame. The lifting bracket drives the desktop to rise and fall and open and close the movable frame of the support frame by setting a control mechanism.

[0023] The bottom of the desktop is fixedly connected to the support frame, and the support frame is fixedly connected to the lifting bracket. The lifting bracket drives the support frame movable frame to open and close by setting a control mechanism.

[0024] By adopting the above technical solution: the control mechanism facilitates controlling the lifting bracket and the support frame to rise, thereby raising the table top; when the lifting bracket rises, the support frame moves upward, thereby raising the movable frame inside the support frame; when the required height is adjusted, the control mechanism can be closed, thereby facilitating adjustment of the height of the table to meet usage requirements.

[0025] The top and one side of the bottom movable frame of the support frame and the upper and lower sides of several movable frames in the middle are respectively provided with notches, and the notches are movably connected to each other by setting a positioning plate.

[0026] A cross bar is fixedly provided on the other side of the movable frame at the top of the support frame, and the cross bar is fixedly connected to the bottom of the desktop and the lifting mechanism.

[0027] The clamping plate is an "I"-shaped structure.

[0028] By adopting the above technical solution: the positioning plate is located between the slots so that the support frames are stretched when the lifting bracket is raised or lowered, and the positioning plate enables the top and bottom movable frames of the support frame and several middle movable frames to stretch and contract as the lifting bracket is raised or lowered; the positioning plate has an "I"-shaped structure so that the top and bottom movable frames of the support frame and several middle movable frames are firmly connected; the cross bar is located above the lifting bracket so that the lifting bracket is easy to connect to the desktop; the cross bar makes the connection between the lifting bracket, the support frame and the desktop more stable.

[0029] The control mechanism includes a gas rod, a fixing part, a connecting part, a pipe, and a switch; the pipe and the switch are connected to the gas rod; the connecting part is located on the lifting bracket; one end of the gas rod is connected to the fixing part; the telescopic shaft on the gas rod is connected to the connecting part; and the switch is located at the bottom of the desktop.

[0030] By adopting the above technical solution: when raising the table, a switch can be toggled to extend the telescopic shaft of the gas rod so that the lifting bracket can be unfolded. After the lifting bracket is unfolded, the height can be increased to raise the table top; gas enters and exits through the pipe.

[0031] The lifting bracket is provided with a slide groove; a bearing wheel is provided in the slide groove; the bearing wheel is connected to the lifting bracket; and the bearing wheel rotates in the slide groove.

[0032] By adopting the above technical solution: there are four bearing wheels and four slide grooves respectively; the bearing wheels and the slide grooves are located on the same side of the lifting bracket and at the edge of the lifting bracket; the bearing wheels slide in the slide grooves to facilitate the lifting of the lifting bracket; the bearing wheels are always located in the slide grooves when the lifting bracket is expanded or retracted.

[0033] To sum up, the utility model has the following beneficial effects: when raising the table, the switch can be toggled so that the telescopic shaft of the gas rod extends from the gas rod, thereby driving the lifting bracket to rise; while the lifting bracket rises, the bearing wheel slides in the slide groove, thereby facilitating the lifting bracket to rise; when the lifting bracket rises, it drives the support frame and the table top to move upward; when it is adjusted to the required height, the switch can be turned off, thereby facilitating the adjustment of the table height to meet usage requirements.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
