Description

Technical Field

[0001] The utility model relates to the technical field of electric fans, and more specifically, the utility model relates to a combined electric fan bracket. Background Art

[0002] Electric fans are necessities in family life and work. Compared with air conditioners, electric fans still occupy a large market share due to their economy and natural ventilation function during use. For electric fans, low price and simplicity and practicality are the first considerations of consumers. Usually, in the field of household appliances, the base brackets of electric fans usually adopt longer profiles or pipes, and are fixed and positioned with connecting parts such as screws to form a base, so as to ensure the stability of the electric fan.

[0003] When the existing floor-standing electric fan is not in use, it is difficult to disassemble the base in sections, which is inconvenient for storage.

[0004] After retrieval, the combined electric fan bracket disclosed in the Chinese patent with the publication number of CN220470308U. At the top of each group of support legs of this utility model, a support pipe is fixedly connected. The use of the base body and the support legs reduces the overall center of gravity, making the fan connecting pipe more supportive of the electric fan. The support legs and the connecting rod can be disassembled, which is more conducive to storage than the previous integrated design when not in use usually.

[0005] However, when the above electric fan bracket is actually used, due to different actual use sites, the situation that the placement ground is uneven may occur, which may cause the electric fan to be prone to tipping after being placed, affecting the use safety of the electric fan.

By pushing the push plate 10, the two clamping blocks 14 are squeezed, so that the clamping blocks 14 enter the inside of the chassis 1. Then, the spring 6 pushes the lower support plate 5 and the suction cup 4 to move downward, so that the suction cup 4 can adsorb on the ground. Then, by pulling the push plate 10 again to rotate through the guiding frame 12, the push frame 9 drives the push ring 8 and the lower support plate 5 to move upward, so that the suction cup 4 can be separated from the ground, facilitating the movement of the position of the chassis 1.

Then the spring 6 pushes the lower support plate 5 to move downward, and the lower support plate 5 drives the suction cup 4 to squeeze the ground, so that the suction cup 4 can adsorb to the ground, so that the chassis 1 can be stably fixed on the ground;

[0031] After that, fix the fan on the top of the connecting seat 26. First, pull the secondary support rod 25 upward along the main support rod 20, and then rotate the anti-slip strip 22 to be threadedly connected to the outside of the plurality of threaded pieces 21, so that the plurality of anti-slip strips 22 inside the threaded piece 21 squeeze the outside of the secondary support rod 25, so that the secondary support rod 25 can extend different lengths and then be fixed, so that the height of the fan can be adjusted to a more suitable height according to its own use.
