Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan with an adjustable base. Background Art

[0002] The function of industrial fans is to achieve ventilation, cooling, exhaust and other functions by generating airflow. They are often used in industrial production processes to control temperature, humidity, air quality, etc.

[0003] However, the existing industrial fans are installed on the bracket through the base during use. When there is a vertical height difference between the air ducts, the base of the fan needs to be disassembled and reassembled to adapt to the corresponding air ducts. The inability to adjust the fan base vertically and rotationally means that it cannot be adjusted according to specific needs, which will cause the fan to fail to fully cover the required area or angle, thereby affecting the ventilation effect. To this end, we propose a fan with an adjustable base to solve the existing problem. Utility Model Content

[0004] The utility model aims to solve the problems existing in the background technology and proposes a fan with an adjustable base.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fan with an adjustable base, comprising a fan, a mounting plate, a bottom plate, a shear arm, a motor, a base and a threaded block, wherein a motor is arranged at the upper end of the base, a bottom plate is arranged above the base, a mounting plate is arranged above the bottom plate, a fan is arranged at the upper end of the mounting plate, a mounting shaft is arranged at the lower end of the fan, a latch is slidably inserted inside one end of the mounting plate, a symmetrically distributed mounting seat 2 and a mounting seat 1 are respectively arranged at the upper and lower ends of the shear arm, a threaded block is arranged at the lower end of the mounting seat, a screw is arranged at one end of the motor, a slider is arranged at the lower end of the threaded block and the upper end of the mounting seat 2, a slide groove is opened inside the lower end of the bottom plate and the upper end of the base, and the slider is slidably installed inside the slide groove.

[0006] When using a fan with an adjustable base in the present solution, the motor drives the screw to rotate, and the screw pushes the threaded raceway inside the threaded block. The lower end of the threaded block is guided by the slider to achieve relative or opposite movement. The shear arm is rotatably installed between the mounting seat one and the mounting seat two. When squeezed, the shear arm connection rotates. When rotating, the shear arm at the connection unfolds and pushes the bottom plate at the upper end. During the process on the bottom plate, the mounting plate is longitudinally guided by the guide rod, so that the fan can move longitudinally stably. The fan is adjusted in height, and the fan rotates inside the damping roller through the mounting shaft. During the rotation process, the pin is fixed to the positioning hole at the corresponding position by the elastic force of the spring to fix the bottom plate.

[0007] Preferably, a damping roller is embedded in the upper end of the bottom plate, the lower end of the installation shaft is rotatably inserted into the damping roller, and the threads on the outer wall of the screw are relatively distributed. A damping element is arranged inside the damping roller to apply a certain friction force to the rotating installation shaft.

[0008] Preferably, the shear arm is located between the bottom plate and the base, and the lower end side of the mounting plate is provided with equally spaced pulleys, and the lower end of the pulley is rollingly mounted on the upper end of the bottom plate. When the mounting plate rotates, the pulley provides rolling support for the bottom of the mounting plate.

[0009] Preferably, a through hole is provided inside the mounting plate, a guide rod is slidably inserted inside the through hole, and the lower end of the guide rod is connected to the base. The guide rod slides inside the through hole, and when the mounting plate is lifted, the mounting plate slides relatively because of the bottom plate slidably mounted with the slider, thereby ensuring the stability of the longitudinal movement of the mounting plate when it is pushed by the slider.

[0010] Preferably, a spring connected to the inner wall of the upper end of the bolt and the upper end of the mounting plate is sleeved on the outer side of the bolt, and the upper end of the bottom plate is provided with equidistantly distributed positioning holes, which correspond to the bolt. The bolt is elastically supported by the spring, and one end located inside the positioning hole is elastically pressed and held to maintain stability.

[0011] Preferably, the first and second mounting seats are rotatably mounted on both ends of the shear arm, the shear arm is a shear rod distributed longitudinally, the shear rods are cross-distributed, the cross-corresponding positions are rotatably mounted, and the shear rods at the upper and lower corresponding positions are rotatably mounted. The shear rods inside the shear arm and between the shear rods and the first and second mounting seats are rotatably mounted, and the rotation is realized when the extrusion force acts.

[0012] Preferably, a bearing seat is provided on one side of the upper end of the base, and one end of the screw is rotatably mounted inside the bearing seat. One end of the screw is supported by the bearing seat for rotation, and the rotation is more stable.

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

[0014] 1. The utility model sets a shear arm on the base of the fan. The shear arm is a transmission part of the screw force. By pushing the threaded block, the extrusion force and outward pulling force applied by the threaded block act on the shear arm according to the rotation direction of the screw, so that the shear arm can be expanded and stored, and the fan can be adjusted to adjust the longitudinal height. At the same time, the fan is adjusted in the corresponding direction through the installation shaft, which provides better adaptation flexibility during installation. The machine can accurately aim at the target area and provide the best ventilation effect. BRIEF DESCRIPTION OF THE DRAWINGS
