Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to a clamping device for a fan. Background Art

[0002] Fans are common electrical appliances that are widely used in homes, offices, factories, and other scenarios to provide ventilation, heat dissipation, and air circulation. There are many types of fans, including desktop fans, floor fans, ceiling fans, etc. Among them, clip-on fans are favored by more and more users due to their portability and flexibility. Clip-on fans can be easily installed on the side of a table, bed, or other supports to provide fixed-point cooling or ventilation functions.

[0003] For example, the utility model with publication number CN219953760U discloses a small fan that is easy to adjust. The fan is inserted with a torsion spring between the base and the clamping plate. When the clamping plate is pressed, the torsion spring is compressed, causing the clamping plate to open, and the user can clamp the fan in the desired position. After the clamping plate is released, the torsion spring returns to its original state, causing the clamping arm to close again, thereby firmly clamping the clamped object. This clamping method allows the fan to be fixed in various positions and the angle of the fan can be adjusted as needed.

[0004] However, the above-mentioned fan does not provide a sufficient adjustment range due to the fixed structure of the clamping piece, and cannot ensure that the clamping piece can be in close contact with the clamped object. For example, when clamping a thick desktop, the clamping plate may not be completely closed, resulting in the clamping piece and the desktop not being in close contact, which in turn causes the fan to be unstable and easy to fall off. This not only affects the stability and safety of the fan, but also reduces the applicability of the fan, and cannot fully meet diverse needs. Utility Model Content

[0005] In order to improve the problem that the supporting member on the fan cannot ensure close contact between the clamping member and the clamped object due to the fixed structure of the clamping member, thereby affecting the stability and safety of the fan, the present application provides a clamping device for the fan.

[0006] The fan clamping device provided in the present application adopts the following technical solution:

[0007] A fan clamping device, comprising:

[0008] Base;

[0009] A clamping assembly, the clamping assembly comprising a clamping arm, a clamping block and a torsion spring, the clamping arm being arranged on the base and rotatably connected to the base, a hinged portion being fixedly arranged at one end of the clamping arm, a rotating portion being arranged at the end of the clamping block, and the clamping block being rotatably connected to the hinged portion via the rotating portion;

[0010] The torsion spring is arranged between the clamping arm and the base, one end of the torsion spring is connected to the base, and the other end of the torsion spring is connected to the clamping arm.

[0011] By adopting the above technical solution, by rotating the clamping block connected to the clamping arm, the clamping block can be in close contact with the clamped object during the clamping process, ensuring that the fan can be firmly clamped on the clamped object, which can effectively improve the stability and safety of the fan.

[0012] Optionally, the clamping block is configured as a rectangular block, and the clamping block is covered with a first elastic pad, and the first elastic pad is fixedly connected to the clamping block.

[0013] By adopting the above technical solution, the first elastic pads provided on the rectangular blocks can firstly increase the friction force to ensure that the object is firmly clamped and will not slip. Secondly, they reduce the direct contact between the rectangular blocks and the clamped object to prevent damage or scratches, thereby protecting the appearance of the clamped object. At the same time, the first elastic pads provide a certain degree of elasticity, which can adapt to objects of different shapes and thicknesses, thereby improving the flexibility of the clamping assembly.

[0014] Optionally, a first anti-slip groove is provided on one surface of the first elastic pad, and a first clamping groove is provided on a surface of the first elastic pad facing away from the first anti-slip groove, and the first clamping groove is configured as an arc-shaped groove.

[0015] By adopting the above technical solution, the first anti-slip groove and the arc groove provided on the first elastic pad can effectively adapt to clamped objects of different shapes, thereby ensuring the clamping and fixing effect of the clamping assembly, making it difficult for the fan to fall off.

[0016] Optionally, the rotating part is configured as a rotating shaft, one end of the rotating shaft is fixedly connected to one end of the clamping block, the other end of the rotating shaft is rotatably connected to one end of the hinged part, and the clamping block is rotatably connected to the hinged part via the rotating shaft.

[0017] By adopting the above technical solution, the clamping block can rotate freely, and the clamping block can ensure that the clamping assembly and the clamped object can be in close contact, thereby effectively improving the stability and safety of the fan.

[0018] Optionally, a locking block is provided on the rotating shaft, and an external thread is provided at one end of the rotating shaft away from the rectangular block, and the end of the rotating shaft provided with the external thread passes through the hinge part and is threadedly connected to the locking block, and the locking block abuts against the hinge part.

[0019] By adopting the above technical solution and providing the locking member, it is possible to avoid poor clamping and fixing effects caused by shaking or oscillating of the fan during operation, thereby ensuring the overall stability of the fan.

[0020] Optionally, the clamping block is configured to be in the shape of a triangular prism, and the three side surfaces of the clamping block are respectively a first clamping surface, a second clamping surface and a third clamping surface, a plurality of wedge blocks are fixed on the first clamping surface, a second anti-slip groove is provided on the second clamping surface, a second clamping groove is provided on the third clamping surface, and the second clamping groove is configured to be an arc groove.

[0021] By adopting the above technical solution, by setting the clamping block into a triangular prism shape, during the clamping process, the external force required to rotate the triangular prism is much greater than the external force required to rotate clamping blocks of other shapes, so that it is not easy to flip when clamping with the triangular prism-shaped clamping block, thereby ensuring that the clamping assembly can clamp stably.

[0022] Optionally, the rotating part is configured as a bolt, the bolt comprising a screw portion and a bolt head, the screw portion passes through the hinge portion and is threadedly connected to the clamping block, the screw portion is rotationally connected to the hinge portion, and the bolt head abuts against the hinge portion.

[0023] By adopting the above technical solution, the provided bolts can serve as both the rotating shaft of the clamping block and the locking member, which not only reduces the use cost, but also avoids the poor clamping and fixing effect caused by the shaking or swinging caused by the operation of the fan, thereby ensuring the overall stability of the fan.

[0024] Optionally, the base includes a clamping portion, which is fixedly arranged at one end of the base, and the clamping portion can abut against the clamping block. A second elastic pad is arranged on the clamping portion, and the second elastic pad is fixedly connected to the clamping portion.

[0025] By adopting the above technical solution, the elastic pad can be provided to improve the clamping effect, increase adaptability, and provide protection for the clamped object. At the same time, the friction force can also be increased to ensure that the clamped object can be firmly clamped and will not slip.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By rotating the clamping block connected to the clamping arm, the clamping block can be in close contact with the clamped object during the clamping process, ensuring that the fan can be firmly clamped on the clamped object, which can effectively improve the stability and safety of the fan;

[0028] 2. The first elastic pads provided on the rectangular blocks can firstly increase the friction force to ensure that the object is firmly clamped and will not slip. Secondly, they reduce the direct contact between the rectangular blocks and the clamped object to prevent damage or scratches, thereby protecting the appearance of the clamped object. At the same time, the first elastic pads provide a certain degree of elasticity, which can adapt to objects of different shapes and thicknesses, thereby improving the flexibility of the clamping assembly;

[0029] 3. The provided bolts can serve as both the rotating shaft of the clamping block and the locking member, which not only reduces the use cost, but also avoids the poor clamping and fixing effect caused by the shaking or swinging of the fan during operation, thereby ensuring the overall stability of the fan.
