Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and in particular relates to a fan blade and a heat dissipation fan. Background Art

[0002] A cooling fan is a device that can help lower the temperature of electronic equipment. It circulates air to expel the heat inside the equipment, keeping the equipment within the normal operating temperature range, thereby avoiding overheating and extending the service life of the equipment. Therefore, cooling fans are widely used in computers, communication products, optoelectronic products, consumer electronics, automotive electronic equipment, switches and other equipment.

[0003] The cooling fan is generally composed of a motor, internal components (including circuit boards, IC components, LED lights, etc.), bearings, blades, outer frames and other components. The number of blades of a cooling fan is usually between 6 and 12, and is generally an integrated structure. When one of the blades is damaged, the user cannot remove the damaged blade alone, but needs to remove and replace all the blades. This not only easily increases the maintenance cost of the cooling fan, but also easily causes inconvenience in removing the blades, which is not conducive to the rapid maintenance of the cooling fan.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a fan blade and a heat dissipation fan.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, a fan blade in an embodiment of the utility model includes a rotating disk 1 and a plurality of fan blade assemblies 2.

[0034] Among them, a number of evenly distributed protrusions 101 are connected to the outer side of the circumference of the turntable 1, and mounting grooves 102 are opened in the protrusions 101. The mounting grooves 102 are used to install the mounting plate 201 so as to achieve the fixation of the fan blade assembly 2 and the turntable 1.

[0035] Preferably, the cross-sectional shape of the mounting groove 102 is T-shaped, and the mounting plate 201 is adapted to the mounting groove 102, which can ensure the snap-fitting effect between the mounting plate 201 and the mounting groove 102, so that the fan blade assembly 2 is not easy to separate from the turntable 1, thereby ensuring the installation firmness of the fan blade assembly 2.

[0036] like Figures 1 to 6 As shown, a plurality of fasteners 103 are installed on the protrusion 101, and the plurality of fasteners 103 are staggeredly installed on both sides of the installation slot 102. The fasteners 103 can be used to further fix the turntable 1 and the fan blade assembly 2, so that the fan blade assembly 2 can be firmly installed in the installation slot 102, and it is not easy to affect the overall use of the turntable 1 and the fan blade assembly 2.

[0037] The fastener 103 includes a pin 1031, which is movably disposed in the protrusion 101. A plurality of fixing grooves 203 are formed on the mounting plate 201, and the fixing grooves 203 correspond to the pin 1031. One end of the pin 1031 is inserted into the fixing groove 203. By inserting the pin 1031 into the fixing groove 203, the mounting plate 201 can be fixed in the mounting groove 102, so that the mounting plate 201 is not easy to slide relatively in the mounting groove 102, thereby ensuring the installation firmness of the fan blade assembly 2.

[0038] In addition, a plurality of cavities 105 are formed in the protruding portion 101 , and the cavities 105 correspond to the pins 1031 . The cavities 105 are used to accommodate the springs 1033 , and the side walls of the pins 1031 located in the cavities 105 are connected to the limit rings 1032 .

[0039] Specifically, a spring 1033 is provided in the cavity 105, and the spring 1033 is provided on the outside of the pin 1031 and on the side of the stop ring 1032 away from the mounting plate 201. Through the cooperation between the stop ring 1032 and the spring 1033, the pin 1031 can be inserted into the fixing groove 203 in a natural state, thereby ensuring the fixing effect of the fastener 103 on the turntable 1 and the fan blade assembly 2, so that the fan blade assembly 2 is not easy to be separated from the turntable 1.

[0040] In addition, one end of the pin 1031 close to the mounting plate 201 is rotatably connected to a ball 1034 to facilitate removal of the fan blade assembly 2.

[0041] like Figures 1 to 6 As shown, a pair of side walls of the mounting groove 102 are connected with a slide bar 104, a pair of side walls of the mounting plate 201 are provided with a slide groove 204, and the slide bar 104 is arranged in the slide groove 204. By engaging the slide bar 104 in the slide groove 204, the connection firmness between the fan blade assembly 2 and the rotating disk 1 can be further increased.

[0042] like Figures 1 to 6 As shown, several fan blade assemblies 2 are connected to the turntable 1, and the fan blade assembly 2 includes a mounting plate 201, which is slidably arranged in the mounting groove 102, and the blade 202 is fixedly connected to the mounting plate 201 to ensure the connection strength between the mounting plate 201 and the blade 202. The mounting plate 201 is engaged with the fastener 103, and the mounting plate 201 can slide in the mounting groove 102 to realize the disassembly of the fan blade assembly 2, thereby facilitating the user to separately disassemble the damaged fan blades of the cooling fan, which can not only reduce the maintenance cost of the cooling fan, but also reduce the maintenance difficulty of the cooling fan and improve the maintenance efficiency of the cooling fan.

[0043] Among them, the mounting plate 201 is provided with a plurality of slideways 205, and the plurality of slideways 205 are respectively connected with the plurality of fixing grooves 203. When the fan blade assembly 2 needs to be removed, the pin 1031 is first pulled to disengage the pin 1031 from the fixing groove 203, and then the mounting plate 201 is moved to allow the ball 1034 to enter the slideway 205. At this time, the pin 1031 is released, and the ball 1034 can contact the side wall of the slideway 205. The mounting plate 201 is continuously moved, and the ball 1034 will roll, so that the user does not need to keep pulling the pin 1031, and the fan blade assembly 2 can be removed conveniently.

[0044] In specific use, when the user needs to replace the damaged fan blade assembly 2, first pull the pin 1031 to make one end of the pin 1031 disengage from the fixing groove 203. Move the mounting plate 201 so that the ball 1034 can move to the upper side of the slideway 205. At this time, release the pin 1031 so that the ball 1034 can contact the side wall of the slideway 205. Continue to move the mounting plate 201, and the ball 1034 will roll in the slideway 205 until the mounting plate 201 completely slides out of the mounting groove 102. Through the arrangement of the ball 1034 and the slideway 205, the user does not need to keep pulling the pin 1031, and it is convenient to remove the fan blade assembly 2.

[0045] When the fan assembly 2 needs to be installed, the pin 1031 is pulled first, and then the mounting plate 201 is aligned with the mounting groove 102 and inserted so that the ball 1034 on the pin 1031 is in the slideway 205. The mounting plate 201 is pushed continuously until one end of the pin 1031 can be inserted into the fixing groove 203 under the action of the stop ring 1032 and the spring 1033, and the fan assembly 2 and the turntable 1 can be installed and fixed.

[0046] The turntable 1 and the fan blade assembly 2 in the present application adopt a split design, which can facilitate users to separately remove damaged fan blades of the cooling fan, which can not only reduce the maintenance cost of the cooling fan, but also reduce the maintenance difficulty of the cooling fan and improve the maintenance efficiency of the cooling fan.
