The lifting pneumatic rod 3 includes an upper cylinder housing 36. A high-pressure air chamber A and a communication air chamber B are provided in the inner cavity of the upper cylinder housing 36, and the high-pressure air chamber A and the communication air chamber B are interconnected. A upper plug column 31 is slidably connected at the through hole of the high-pressure air chamber A. A locking bolt 32 is fixedly connected below the upper plug column 31. A lower plug column 33 is slidably connected at the lower through hole of the high-pressure air chamber A. A piston plate 35 is fixedly connected to the upper end of the lower plug column 33. The upper cylinder housing 36 is sleeved in the inner cavity of the lower cylinder housing 34.

[0007] Further, one side of the control button 1 is provided with a button inclined surface 1A with a certain inclination, and the upper end of the upper plug column 31 is matched with the button inclined surface 1A.

[0008] Further, a connection bolt hole 201 for connecting the electric fan head is opened on the electric fan connection end 2.

[0009] After adopting the above technical solutions, the beneficial effects of the utility model are as follows: The electric fan support rod of the utility model adopts a lifting pneumatic rod, so that it has a certain boosting effect. When the user needs to adjust the height of the support rod, the user only needs to press the control button and apply a certain pressure or lifting force to the electric fan head to complete the height adjustment of the support rod, which can facilitate the user to more quickly adjust the height of the support rod and is more practical and convenient.

Detailed implementation manners

[0016] Refer to Figures 1-4 As shown, the technical solution adopted in this detailed implementation manner is as follows: It includes a lifting pneumatic rod 3. The upper end of the lifting pneumatic rod 3 is installed with a fan connection end 2. A control button 1 is provided on the fan connection end 2. The control button 1 is mechanically connected to the lifting pneumatic rod 3, and a support bottom plate 4 is installed at the bottom of the lifting pneumatic rod 3. The lifting pneumatic rod 3 includes an upper cylinder housing 36. The inner cavity of the upper cylinder housing 36 is provided with a high-pressure air chamber A and a connecting air chamber B, and the high-pressure air chamber A and the connecting air chamber B are interconnected. A upper plug column 31 is slidably connected at the through hole of the high-pressure air chamber A. A clamping bolt 32 is fixedly connected below the upper plug column 31. A lower plug column 33 is slidably connected at the lower through hole of the high-pressure air chamber A. A piston plate 35 is fixedly connected to the upper end of the lower plug column 33. The upper cylinder housing 36 is sleeved in the inner cavity of the lower cylinder housing 34.

[0017] More specifically, one side of the control button 1 is provided with a button inclined surface 1A with a certain inclination, and the upper end of the upper plug column 31 is matched with the button inclined surface 1A.

[0018] More specifically, a connecting bolt hole 201 for connecting the fan head is provided on the fan connection end 2.

[0019] Working principle of the utility model: When in use, the staff only needs to install the electric fan head on the fan head connection end 2 and fix it with bolts. After installation, it can be used normally. When the height of this support rod needs to be adjusted, the user only needs to press the control button 1. At this time, the control button 1 will cooperate with the top of the upper plug column 31 through the button inclined surface 1A, so that the upper plug column 31 moves downward. At this time, the upper and lower parts of the high-pressure air chamber A will be connected under the action of the connecting air chamber B. And the user only needs to apply a certain additional pressure or lifting force to quickly adjust the relative height of the lower cylinder housing 34 and the upper cylinder housing 36. After the adjustment is completed, release the control button 1, and the upper plug column 31 and the clamping bolt 32 will return to their original states, making the upper and lower parts of the high-pressure air chamber A become independent air chambers, thereby fixing the relative height of the lower cylinder housing 34 and the upper cylinder housing 36.

[0020] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent substitutions made by those of ordinary skill in the art to the technical solution of the present utility model shall be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
