[0015] The present disclosure is described in further detail below with reference to the drawings.

[0016] Embodiments provide a pneumatic lift table. Referring to FIG. 1 to FIG. 6, the present disclosure has effect of adjusting a height of the table. The pneumatic lift table includes a table top. A bottom of the table top is fixedly connected to a lifting support and a support frame. The support frame includes a plurality of movable frames that are mutually movably fitted with each other. The lifting support drives, by setting a control mechanism, the table top to ascend or descend or drives the movable frame of the support frame to be opened or closed.

[0017] The bottom of the table top is fixedly connected to the lifting support, the lifting support is fixedly connected to the support frame, and the lifting support drives, by setting the control mechanism, the table top to ascend or descend and drives the movable frame of the support frame to be opened or closed.

[0018] The bottom of the table top is fixedly connected to the support frame, the support frame is fixedly connected to the lifting support, and the lifting support drives, by setting the control mechanism, the movable frame of the support frame to be opened or closed.

[0019] In the above technical solution, the lifting support and the support frame may be ascended due to the control mechanism, to enable the table top to be ascended. While the lifting support is ascended, the support frame moves upward, to enable the movable frame in the support frame to be ascended. When the height is adjusted to a required height, the control mechanism may be turned off, to adjust the height of the table, thereby meeting the usage requirements.

[0020] A lateral surface of a top movable frame, a lateral surface of a bottom movable frame, and upper lateral surfaces and lower lateral surfaces of a plurality of middle movable frames of the support frame are all provided with notches; and the notches are movably connected to each other in a fitting manner by setting a clamping plate.

[0021] A cross rod is fixedly disposed on another lateral surface of the top movable frame of the support frame, and the cross rod is fixedly connected to the bottom of the table top and a lifting mechanism.

[0022] The clamping plate has an I-shaped structure.

[0023] In the above technical solution, the clamping plate is located between the notches. Therefore, the support frames are stretched when the lifting support is ascended and descended. Due to the clamping plate, the top movable frame, the bottom movable frame, and the plurality of middle movable frames of the support frame are stretched and contracted when the lifting support is ascended and descended. Because the clamping plate has an I-shaped structure, the top movable frame, the bottom movable frame, and the plurality of middle movable frames of the support frame are connected firmly. The cross rod is located above the lifting support, to enable the lifting support to be conveniently connected to the table top. Due to the cross rod, a connection among the lifting support, the support frame, and the table top is more stable.

[0024] The control mechanism includes a pneumatic rod, a fixing portion, a connection portion, a pipeline, and a switch; the pipeline and the switch are connected to the pneumatic rod; the connection portion is located on the lifting support; one end of the pneumatic rod is connected to the fixing portion; a telescopic shaft on the pneumatic rod is connected to the connection portion; and the switch is located at the bottom of the table top.

[0025] In the above technical solution, when the table is ascended, the switch may be toggled, to enable the telescopic shaft of the pneumatic rod to extend outside, thereby enabling the lifting support to be stretched. After the lifting support is stretched, the height is increased, thereby enabling the table top to be ascended. The pneumatic rod extends inward or outward through the pipeline.

[0026] The lifting support is provided with a sliding groove; a bearing wheel is disposed in the sliding groove; the bearing wheel is connected to the lifting support; and the bearing wheel rotates inside the sliding groove.

[0027] In the above technical solution, there are four bearing wheels and four sliding grooves. The bearing wheels and the sliding grooves are located on a same side of the lifting support and at an edge of the lifting support. The bearing wheels slide in the sliding grooves, to facilitate the lifting support to be raised. When the lifting support is stretched or contracted, the bearing wheels are always located in the sliding grooves.

[0028] To sum up, the present disclosure has the following beneficial effect: When the table is ascended, the switch may be toggled, to enable the telescopic shaft of the pneumatic rod to extend from the pneumatic rod, thereby driving the lifting support to be ascended. While the lifting support is ascended, the bearing wheel slides inside the sliding groove, to facilitate the lifting support to be ascended. When the lifting support is ascended, the support frame and the table top are driven to move upward. When the height is adjusted to a required height, the switch may be turned off, to adjust the height of the table, thereby meeting the usage requirements.

[0029] The above descriptions are merely preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modification, equivalent substitute and improvement without departing from the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.

[0030] 6. The pneumatic lift table according to claim 4, wherein a cross rod is disposed on the lifting support, and the cross rod is fixedly connected to the bottom of the table top and the support frame.
