Description

Technical Field

[0001] The utility model relates to the technical field of electric fans, and particularly relates to a floor fan base with good stability. Background Art

[0002] A fan is a tool used to generate wind and cool off in hot weather. An electric fan is a device that uses electricity to drive the generation of air flow. The fan inside is rotated after being powered on to form natural wind to achieve the effect of cooling off.

[0003] A floor fan is a type of electric fan, named because its bottom angle touches the ground. A floor fan can be adjusted in height and has two types: oscillating and swing-out louver. The wind speed of a floor fan can be divided into three gears: high, medium, and low. The trendy detachable chassis design of a floor fan is suitable for household use and is a must-have item in summer. A base is usually installed at the bottom end of a floor fan, but the existing floor fan base has the problems of simple structure and poor stability.

[0004] Therefore, we propose a floor fan base with good stability. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a floor fan base with good stability. Through the threaded fit of the lead screw with the top plate and the cylinder, the lead screw can push the limiting plate downward until the suction cup on the lower end surface of the limiting plate tightly adheres to the ground, thereby improving the stability of the support plate and further improving the stability of the floor fan, and effectively solving the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A floor fan base with good stability includes a fan head, a mounting bracket, and a base mechanism. The upper part of the mounting bracket is assembled with the fan head, and the bottom end of the mounting bracket is connected to the base mechanism. The base mechanism includes a mounting plate, a support plate, balls, a cylinder, a limiting component, a fixing bolt, a bearing, a top plate, and a socket. The support plate is a horizontally arranged circular plate structure, the mounting plate is an annular structure, the mounting plate is located directly above the support plate, and balls are provided between the mounting plate and the support plate;

[0008] A cylinder is fixedly connected to the center of the upper end surface of the support plate, and sockets for assembling the mounting bracket are also fixedly connected to both ends of the upper end surface of the support plate. The mounting plate is sleeved on the cylinder through a bearing. A circular plate-shaped top plate is fixedly connected to the top of the cylinder, the top plate is fixedly connected to the mounting plate through a fixing bolt, and a cavity for installing a limiting component is provided at the center of the lower end surface of the support plate.

[0009] By adopting the above technical solution, the mounting plate can rotate through the bearing and the ball, and the mounting plate drives the mounting frame and the fan head to rotate, so that the orientation of the fan head can be adjusted, enabling the floor fan to be used flexibly, and thus improving the practicality of the floor fan.

[0010] Specifically, two groups of sockets are arranged in parallel, and the bottom end of the mounting frame is inserted into the socket.

[0011] Specifically, a plurality of balls are provided, and sliding grooves adapted to the balls are provided on the lower end surface of the mounting plate and the upper end surface of the support plate. The sliding groove is of an annular structure.
