Small fan for preventing automatic rotation during working

Abstract

The invention provides a small fan for preventing automatic rotation during working. The small fan comprises a base, nuts are movably mounted at the left side and the right side of the base, grooves are formed at the bottoms of the nuts, telescopic springs are fixedly mounted in inner cavities of the grooves, and buttons are fixedly mounted at the bottoms of the telescopic springs. According to the small fan for preventing automatic rotation during working, by arranging a movable rod and a fixing hole, the movable rod and the fixing hole are matched in shape and size, after the fan is installed, the angle of the fan is frequently adjusted due to various reasons during working, but the nuts are prone to loosening after being used for a long time, and therefore the fan body automatically slides down; and at the moment, the buttons are pressed, a threaded pipe is used for driving a first mounting block to rotate, a movable rod is controlled to extend out of the nuts and be movably mounted in the fixing hole in cooperation with the state that the first mounting block and a second mounting block are combined after rotating, and therefore the effect of preventing the fan from automatically rotating by an angle in the using process is achieved.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a small fan used to prevent automatic rotation during operation. Background technique [0002] As the global greenhouse effect continues to intensify, the temperature in various regions at the same time is higher than before, so that the temperature in summer is getting higher and higher, and fans and air conditioners are almost inseparable in life. Therefore, every summer, various fans 1. The orders of air conditioner manufacturers are increasing wildly, because air conditioners are difficult to carry and carry, and due to space factors, the ambient temperature in different places in the same place is not the same, and everyone's heat resistance experience is also different. [0003] Therefore, in many office places, various small fans can be seen everywhere. However, due to reasons such as volume and gravity of the central axis, such small fans often rotate and collapse after a pe...

Problems solved by technology

[0003] Therefore, in many office places, various small fans can be seen everywhere. However, due to the size and the gravity of the central axis, these small fans often rotate and collapse after a period of use, which affects the comfort of users. Due to environmental and other reasons, after a small fan is used for a period of time, various types of dust are attached to the top surface of the fan blades. If it is not cleaned for a long time, it will easily affect the wind power of the fan.
