Description

Technical Field

[0001] The utility model relates to the technical field of fan covers, in particular to a fan cover of a table fan. Background Art

[0002] A table fan is a household appliance that uses an electric motor to drive the fan blades to rotate to accelerate air circulation. It is mainly used to cool down and circulate air. It is widely used in homes, classrooms, offices, shops, hospitals, hotels and other places. In order to avoid exposing the fan blades, it is usually necessary to install a fan cover on the table fan to prevent the rotating fan blades from injuring people.

[0003] The fan cover of the existing table fan is usually an integrated structure when it is installed. After the fan cover is installed on the table fan, dust easily falls on the surface of the fan blades after long-term use, affecting the rotation of the fan blades. Therefore, the fan blades need to be disassembled and cleaned regularly. The existing integrated structure of the fan cover is not convenient for personnel to disassemble. For this reason, we propose a fan cover for the table fan to facilitate the disassembly of the fan cover and the cleaning of the fan blades. Utility Model Content

The connecting mechanism is composed of a connecting plate A, a locking bolt, an arc groove, a connecting plate B, a clamping hoop B and an internal threaded tube. The two ends of the clamping hoop A are welded with connecting plates A, and the locking bolt is threadedly connected to the plate wall of the connecting plate A. The two ends of the clamping hoop B are welded with connecting plates B, and the plate wall of the connecting plate B is connected and welded with an internal threaded tube, and the internal threaded tube is threadedly connected to the locking bolt. A group of symmetrical arc grooves are provided on the inner wall of the clamping hoop A and the inner wall of the clamping hoop B.

[0006] By adopting the above technical solution, when installing the fan cover, since the two ends of the tight clamp A are equipped with connecting mechanisms, the connecting mechanism is composed of a connecting plate A, a locking bolt, an arc groove, a connecting plate B, a tight clamp B and an internal threaded tube. After the personnel pass the external threaded bolt through the through hole, the external bolt is connected to the shell wall of the table fan. Since a group of symmetrical arc grooves are opened on the inner wall of the tight clamp A and the inner wall of the tight clamp B, the personnel insert the steel ring A and the steel ring B into the arc grooves respectively. Since the two ends of the tight clamp A are welded with connecting plates A, and the two ends of the tight clamp B are welded with connecting plates B, the locking bolt and the internal threaded tube are connected. After the threaded connection, the connecting plate A is connected to the connecting plate B. Since a group of symmetrical arc grooves are opened on the inner wall of the tight clamp A and the inner wall of the tight clamp B, the steel ring A and the steel ring B are respectively located in a group of arc grooves. After the steel ring A and the steel ring B are connected, the fan blades of the table fan are located between the steel ring A and the steel ring B. The outer wall of the steel ring A and the outer wall of the circle are welded together through several groups of symmetrical protective rods A, and the outer wall of the steel ring B and the outer wall of the disc are welded together through several groups of symmetrical protective rods B. The blades of the table fan are protected by the protective rods A and the protective rods B, which makes it convenient for personnel to disassemble the steel ring B and thus facilitate the cleaning of the fan blades.

[0007] Specifically, the inner wall of the tight clamp A and the inner wall of the tight clamp B are sleeved and connected with a steel ring A.

[0008] By adopting the above technical solution, it is convenient to fix the steel ring A.

[0009] Specifically, the outer wall of the steel ring A is welded to the outer wall of the circle through several groups of symmetrical protective rods A, and the outer wall of the circle is provided with several groups of through holes connected with external bolts.

[0010] By adopting the above technical solution, the circle can be conveniently connected to the wall of the table fan shell by passing the external bolts through the through hole.

[0011] Specifically, the inner wall of the clamp A and the inner wall of the clamp B are sleeved with a steel ring B, and the outer wall of the steel ring B is welded to the outer wall of the disc through several groups of symmetrical protective rods B.

[0012] By adopting the above technical solution, it is convenient to fix the steel ring B.
