Description

Technical Field

[0001] This utility model relates to the field of fans, specifically a fan structure that can be quickly installed. Background Technology

[0002] A fan is a common mechanical device, usually used for air circulation, heat dissipation, and cooling. Its basic working principle is to drive airflow through rotating blades to generate wind, improve air circulation or lower the temperature. Fans are often used in some electrical appliances to dissipate heat from them.

[0003] Existing fans typically consist of a fan blade assembly and a base. When connecting the fan blade assembly and the base, a T-shaped cap is required. The T-shaped cap is inserted into the inside of the fan blade assembly, and then the T-shaped cap is rotated. The T-shaped cap secures the fan blade assembly to the base through threads. However, the threaded connection method is relatively cumbersome and has poor stability. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a fan structure that can be installed quickly, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fan structure capable of rapid installation, comprising a base and a fan blade assembly. The fan blade assembly is mounted on top of the base, and a fixing plate is movably mounted on the top of the fan blade assembly. A limiting post is fixed to the bottom of the fixing plate, and a slot is provided at the bottom of the limiting post. A first limiting ring is fixed to the top of the base, and a limiting hole is provided inside the base. A second limiting ring is fitted onto the bottom of the limiting post. A wire buckle is provided at the bottom of the base, and a baffle plate is provided above the base, located below the fan blade assembly. A rotor is provided inside the fan blade assembly, and a bearing is provided inside the rotor.

[0006] By adopting the above technical solution, the traditional threaded connection method is replaced by a wire buckle and a second limiting ring. When it is necessary to connect the fan blade assembly and the base, the limiting post at the bottom of the fixing plate is inserted into the inside of the fan blade assembly, and the end of the limiting post enters the inside of the second limiting ring. Then, the wire buckle is inserted into the slot, and the wire buckle enters the inner wall of the limiting groove and the slot, thereby limiting the limiting post and preventing the limiting post from rotating. At the same time, the lower baffle is engaged at the bottom of the base to limit the wire buckle and prevent the wire buckle from falling off.

[0007] The present invention is further configured such that a through hole is provided on the top of the fixing plate, and an avoidance groove is provided on the outer wall of the limiting post, and the avoidance groove is connected to the through hole.

[0008] Preferably, the through holes and clearance slots allow the power cord to pass through easily, facilitating connection and preventing the power cord from being exposed and easily damaged.

[0009] The present invention is further configured such that an upper cover is fitted on the outer wall of the fixing plate, and an installation groove is provided inside the upper cover, and a cover plate is installed on the inner wall of the installation groove.

[0010] Preferably, the top cover and cover plate can easily protect the fixing plate, preventing it from being easily damaged, and also protect the power cord inside the fixing plate.

[0011] The present invention is further configured such that an insertion hole is provided in the middle of the second limiting ring, and a rectangular groove is provided on one side of the outer wall of the second limiting ring.

[0012] Preferably, the opening allows the second limiting ring to be easily fitted onto the outer wall of the limiting post, and the rectangular groove allows the power cord to pass through easily.

[0013] The present invention is further configured such that the outer wall of the second limiting ring is fixed with a first fixing piece and a second fixing piece.

[0014] Preferably, the first and second fixing pieces are located on both sides of the base, thereby limiting the second limiting ring.

[0015] The present invention is further provided that the bottom of the base has a slot.

[0016] Preferably, the slot allows for easy insertion of the clasp.

[0017] The present invention is further configured such that a limiting groove is provided at the bottom of the limiting ring.

[0018] Preferably, the limiting groove allows the wire buckle to be easily inserted into its inner wall, thereby limiting the positioning of the limiting ring.

[0019] The present invention is further provided with a lower baffle at the bottom of the base and an upper baffle at the top of the cover plate.

[0020] Preferably, the upper baffle can easily cover the cover plate, preventing the cover plate from affecting the aesthetics, while the lower baffle can easily block the wire buckle, preventing the wire buckle from separating from the base.

[0021] In summary, the present invention has the following main advantages:

[0022] This utility model features a fixed plate, a limiting post, a slot, a second limiting ring, and a wire buckle. The wire buckle and second limiting ring replace the traditional threaded connection. When connecting the fan blade assembly and the base, the limiting post at the bottom of the fixed plate is inserted into the fan blade assembly, with its end entering the second limiting ring. The wire buckle is then inserted into the slot, fitting into the inner wall of the limiting groove and slot, thus limiting the limiting post and preventing it from rotating. Simultaneously, a lower baffle is engaged at the bottom of the base to further limit the wire buckle and prevent it from falling off. Attached Figure Description
