[0002] Axial flow fan, axial flow fan is mainly composed of impeller, casing, motor and other parts, and has a wide range of uses. It is called "axial flow" because the gas flows parallel to the fan shaft. Axial flow fans are usually used in places with high flow requirements and low pressure requirements. Ordinary axial flow fans can be used for ventilation in general factories, warehouses, offices, residences and other places. They can also be used for air coolers, evaporators, condensers, spray drops, etc. There are also axial flow fans for mining. Anti-corrosion and explosion-proof axial flow fans use anti-corrosion materials and explosion-proof measures, and are matched with explosion-proof motors. They can be used to transport explosive, volatile and corrosive gases.

[0003] The existing axial flow fan has some shortcomings: the existing axial flow fan is composed of a fan box and a base, the base is provided with a universal wheel, which can drive the device to move, when the device moves to a fixed position, the first hydraulic rod is provided to support the device, and multiple first hydraulic rods are operated synchronously to improve the stability of the device and avoid the device from tilting, and an adjustment mechanism is provided in the device to adjust the height of the axial flow fan;

[0004] When positioning the mobile component, it is necessary to control multiple groups of hydraulic rods to operate synchronously, but each group of hydraulic rods is set separately. Although the hydraulic rods are synchronously controlled by the hydraulic components, the hydraulic rods will age in different states during operation, which will cause the hydraulic rods to be able to rise and fall to different degrees, resulting in an uneven base of the fan, causing the fan to be tilted when lifted, affecting the stability of use. Utility Model Content

[0005] The utility model aims to provide a mobile axial flow fan, which is used to solve the problem that when positioning a mobile component, it is necessary to control multiple groups of hydraulic rods to operate synchronously, but each group of hydraulic rods is set separately. Although the hydraulic rods are synchronously controlled by the hydraulic components, the hydraulic rods will age in different states during operation, which will cause the hydraulic rods to be able to rise and fall to different degrees, resulting in an uneven base of the fan, causing the fan to be tilted when lifted, affecting the stability of use.

[0006] Therefore, the utility model provides a mobile axial flow fan, including a base plate, a fan, a moving mechanism and a lifting mechanism, wherein a vertical plate is installed at the lower end of the base plate, and the side wall of the vertical plate is provided with a moving mechanism for individual positioning, vertical plates are symmetrically installed at the upper end of the base plate, and a lifting mechanism for adjusting the height of the fan is installed between the vertical plates, a horizontal plate is installed at the upper end of the lifting mechanism, and a fan is installed at the upper end of the horizontal plate, a support rod is installed inside the fan, and a motor is installed on the rear side of the support rod.

[0007] Preferably: the moving mechanism includes a groove, a panel is slidably installed in the groove, shock absorbers are installed on the upper and lower sides of the panel, a spring is sleeved on the outer wall of the shock absorber, a bottom wheel is installed on the outer wall of the panel, a first slot is opened inside the edge of the bottom wheel, a second slot is opened on the side wall of the vertical plate at the upper side of the groove, and rods are inserted in the second slot and the first slot.

[0008] Preferably: the lifting mechanism includes a bottom groove, a first bevel gear is installed inside the front end of the bottom groove, a knob is connected to the front end of the first bevel gear, a second bevel gear is installed on the inner wall of the upper end of the bottom groove, a telescopic groove is opened on the outer side of the upper side of the bottom groove, a screw is installed in the telescopic groove, and a telescopic plate is mounted on the outer wall of the screw.

[0009] Preferably, the panel is connected to one end of the spring, and the other end of the spring is connected to the side wall of the shock absorber.

[0010] Preferably, at least twelve groups of the first slots are provided.

[0011] Preferably, the first bevel gear and the second bevel gear are meshed with each other.

[0012] Preferably: the second bevel gear is connected to the screw.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model discloses that when the fan needs to be moved for use, the insertion rod is pulled outwards to disengage it from the rough first slot and the second slot, and the bottom plate is directly pushed to move the fan under the rotation of the bottom wheel. During the movement, when passing through a bumpy road section, the bottom wheel fluctuates up and down, driving the panel to move up and down in the panel slot. Under the contraction of the shock absorber and the spring, the vibration is buffered to achieve the effect of reducing the bump, thereby improving the stability of the movement. After moving to the position where it needs to be used, the insertion rod is aligned with the first slot and the second slot and positioned under the static friction effect of the rough surface. The timely moving and positioning effect can be achieved, thereby improving the convenience of moving and positioning. The knob is twisted to drive the first bevel gear to rotate and mesh to drive the second bevel gear to rotate, thereby driving the connected screw to rotate. The meshing drives the telescopic plate to move vertically and stably up and down in the telescopic slot to adjust the height of the fan, so that air can be extracted or supplied according to the required height, thereby improving the convenience of using the fan.
