Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a pressure plate. Background Technology

[0002] Currently, ceiling fan blades are typically fixed using a plug-in structure, where the blade slots are inserted into the blade core and then secured with bolts. While this structure is simple to install, it presents problems during operation: the periodic centrifugal force and vibration generated by the high-speed rotation of the fan blades cause the bolts to bear significant stress, leading to gradual loosening of the bolt fit. Loose blades will oscillate radially during rotation, not only producing loud noise but also causing additional off-center loads on the motor bearings, thus affecting the motor's lifespan. Utility Model Content

[0003] In response to the problem that existing ceiling fans tend to loosen between the fan blades and the blade core after prolonged use, resulting in noise when the fan blades rotate, this utility model provides a fan with a pressure plate.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fan with pressure plates includes a fan motor, a plurality of fan blade cores, and a plurality of fan blades. Each fan blade core is fixed to the fan motor, and each fan blade is correspondingly inserted into a fan blade core. The fan includes a plurality of pressure plates connected to the top of the fan blades, and includes a first connecting section and a second connecting section. It also includes a plurality of hub plate rings located between the pressure plates and the fan blade cores, and connected to the pressure plates, fan blade cores, and fan motor.

[0006] Furthermore, a Z-shaped structure is formed between the first connecting segment and the second connecting segment, the first connecting segment is fixedly connected to the hub plate ring, and the fan blade is located between the second connecting segment and the fan blade core.

[0007] Furthermore, the hub plate ring is annular and is sleeved on the motor shaft of the fan motor.

[0008] Furthermore, the height of the first connecting segment relative to the fan blade core is less than the height of the second connecting segment relative to the fan blade core.

[0009] Furthermore, the hub plate ring includes an upper plate ring and a lower plate ring, both of which are polygonal and are fitted onto the motor shaft of the fan motor through mounting holes.

[0010] Furthermore, the upper plate ring is located between the pressure plate and the fan blade core, and the lower plate ring is located between the fan blade core and the fan motor.

[0011] Furthermore, the upper plate ring has notches at the corner positions that are adapted to the fan blades.

[0012] Furthermore, the height of the first connecting segment relative to the fan blade core is greater than the height of the second connecting segment relative to the fan blade core.

[0013] Furthermore, an L-shaped structure is formed between the first connecting segment and the second connecting segment, and the first connecting segment is arc-shaped.

[0014] Furthermore, the second connecting segment is fixedly connected to the fan blade, and the first connecting segment is fixedly connected to the second connecting segment located on the adjacent fan blade.

[0015] The beneficial effects of this utility model are: This utility model increases the contact area between the pressure plate and the fan blade, and uses the hub plate ring to enhance the connection strength between the fan blade core and the fan motor, avoiding loosening between the fan blade and the fan blade core and between the fan blade core and the fan motor, and effectively preventing noise problems after the fan blade has been used for a long time.

Each fan blade core 2 is evenly arranged along the circumference of the fan motor 1 and is fixedly connected to the fan motor 1. One end of each fan blade has a slot adapted to fit the fan blade core 2, allowing it to be inserted into the fan blade core 2 through the slot. The hub plate rings 4 are annular and are fitted onto the motor shaft of the fan motor 1. The hub plate rings 4 are located between the pressure plates 3 and the fan blade cores 2, and are fixedly connected to the pressure plates 3, fan blade cores 2, and fan motor 1 by several bolts. The pressure plates 3 include a first connecting section 301 and a second connecting section 302, forming a Z-shaped structure. The height of the first connecting section 301 relative to the fan blade core 2 is less than the height of the second connecting section 302 relative to the fan blade core 2. The first connecting section 301 is fixedly connected to the hub plate ring 4 by several bolts. The second connecting section 302 is spaced from the fan blade core 2. The upper side of the fan blade end is arranged in the space. The second connecting section 302 is fixedly connected to the fan blade and the fan blade core 2 by several bolts.

Mounting holes are provided at the center of both the upper and lower plate rings 401 and 402, and both are fitted onto the motor shaft of the fan motor 1 through these holes. The upper plate ring 401 is located above the lower plate ring 402, between the pressure plate 3 and the fan blade core 2, while the lower plate ring 402 is located between the fan blade core 2 and the fan motor 1. The corners of the upper plate ring 401 have notches adapted to the end face of the fan blade to increase the depth of insertion of the fan blade into the fan blade core 2. The height of the first connecting section 301 relative to the fan blade core 2 is greater than the height of the second connecting section 302 relative to the fan blade core 2.

[0034] The third embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In this embodiment, the structure of the pressure plate 3 is the same as that of the first and second embodiments.
