Description of the new type: [Technical field to which the new type belongs] This creation relates to a mounting device for a cooling fan, especially a shock-absorbing structure for mounting a cooling fan. [Previous technology] With the rapid development of the electronics industry, the processing capacity of electronic components such as central processing units has been continuously upgraded, and a large amount of heat has been generated during operation. If the heat generated by it is not removed in time, it will cause heat accumulation and increase temperature. The electronic components are operating normally. Generally, the industry installs a cooling fan inside the computer to provide forced airflow to assist its cooling. When the fan is running, cold air from outside enters the inside of the case through the air inlet of the computer case to exchange heat with the central processor and other electronic components, and further exhausts the case through the exhaust hole to take away the heat emitted by the electronic components inside the system. However, if the fan is directly installed on the rack inside the chassis, the fan will generate vibration during operation, which will be transmitted to the rack and generate noise. Therefore, a buffer structure is generally installed between the fan and the rack to prevent the fan from generating. The vibration is transmitted to the rack, thereby reducing the vibration and noise in the system. U.S. Patent No. 5,208,73 discloses a buffer structure in which a frame is provided on the rack to accommodate the cooling fan, and two opposite sides of the frame do not each have a buffer frame, and the fan is mounted on the machine. When the rack is mounted, the pair of buffer 塾 is sandwiched between the fan frame and the frame, so that the frame does not directly contact the frame, and the vibration generated by the fan will not be further transmitted to the frame or even due to the cushion pad's blocking. On the rack, reduce the generation of noise. Although the above buffer structure can effectively prevent the transmission of vibration generated by the fan, thereby reducing the generation of noise ', the buffer junction has a larger volume and requires more materials for production, so the cost is higher. [New content] M269691 The technical problem to be solved in this creation is to provide a lower cost morning cooling structure for cooling fan installation. In order to solve the technical problem of the creation, the installation device of the cooling fan for the creation is used to install the fan on a supporting member, including a fan frame and a buffer device provided on the fan frame. The fan frame is provided with a flange facing the supporting member. The buffer device includes a plurality of buffer gaskets fixed on the flange, and each buffer ring includes an elastic buffer portion located on one side of the flange and extending from the buffer portion and abutting against the other side of the flange so as to The positioning portion of the elastic buffer portion is fixed, and the buffer portion is sandwiched between the flange and the support after assembly. Compared with the prior art, the present invention only has buffer gaskets at the four corners of the fan frame, so the material required for production is greatly Reduce, effectively reduce production costs. [Embodiment] The following further describes this creation with reference to the drawings and embodiments. As shown in the first figure, the cooling fan installation device with shock absorption structure of the present invention includes a fan frame 10 and four buffer rings 20 placed at four corners of the fan frame 10. The fan frame 10 includes a base plate 11, a ring-shaped outer frame 12 extending downward from the periphery of the base plate u, and upper and lower flanges 14 and 13 extending outwardly from both ends of the outer frame 12. The base plate u and the outer frame 12 form an accommodating space for accommodating the fan rotor and the stator. Four perforations 15 are provided on the upper flange 14 at symmetrical intervals, and two sides of each perforation 15 are provided respectively—a slot 16 communicating with the perforation 15. The connection line of the pair of slots 16 is the same as the axis of the perforation 15. on flat surface. The buffer washer 20 is made of an elastic material, such as plastic, rubber, etc. Each buffer washer corresponds to the perforation 15 of the upper flange 14. M269691 Each buffer ring 20 includes a ring portion 22 and two clamping blocks 26 extending downward from the ring portion 22. The round part 22 is provided with a through hole 24, and the diameter of the through hole 24 is larger than the diameter of the through hole 15. When installing the fan, the fixing members such as screws can easily pass through the through hole 24 after passing through the through hole 15, and will not pass through the ring. The portion 22 is in direct contact, thereby preventing the cushion washer 20 from being worn. The blocks 26 are all bar-shaped, and the bottom ends thereof are bent outward to form a horizontal end. The distance between the outer edges of the two ends of the two clamping blocks 26 of each buffer washer 20 is greater than the distance between the outer edges of the slot 16 corresponding to the two sides of the perforation 15 of the buffer washer 20. When the buffer washer 20 is mounted on the fan frame 10, the clamping blocks 26 of each buffer washer 20 are elastically deformed by force, and then slide into the corresponding slot 16 on the upper flange 14 and continue to slide down to make the ends of the clamping block 26 Pass the card slot 16, and then the card block 26 resumes elastic deformation. The card block is housed in the card slot 16, and the end of the card block 26 abuts against the lower surface of the upper flange 14. The through hole 24 of the buffer washer 20 and the corresponding through hole 15 in the upper flange 14 constitute a mounting hole communicating with each other. Since the distance between the outer edges of the two clamping blocks 26 of the buffer washer 20 is greater than the distance between the outer edges of the slot 16 and the outer diameter of the ring portion 22 is greater than the diameter of the perforation 15, the buffer ring 20 is fixed. On the upper flange 14. As shown in the first and second diagrams, the fan is assembled. When the fan is installed in a computer system, the fan can be fixed to the support 30 provided on the rack in various ways, such as a screw lock. . After the fixing members such as screws pass through the perforations 15 of the upper protrusion, the edge 14 and the through holes 24 of the buffer ring 20, they are finally screwed into the mounting holes of the support member 30 to fix the fan on the support member 30. After assembling, the ring portion 22 of the buffer cushion 20 is squeezed between the upper surface of the flange 14 above the fan frame 1C) and the support member 30, so that the fan frame 10 and the support member 30 are not in direct contact. The vibration of the fan will not be transmitted to the support member 30 due to the blocking of the buffer ring 20, thereby reducing the vibration of the M269691 in the system and the resulting noise. In addition, since the buffer washer 20 has a small volume, the material required for manufacturing is greatly reduced, and the manufacturing cost is reduced. In the above embodiment, the ring portion 22 is used as the elastic buffer portion, and the block 26 is used as the positioning portion for fixing the buffer portion. In the above embodiment, the two blocks 26 of the cushion washer 20 and the axis of the ring portion 22 are on the same plane, that is, the pair of the blocks 26 are disposed on the circumference of the ring portion 22 at 18 °. Understandably, the pair of clamping blocks 26 can also be disposed on the annular portion 22 at various angles. As shown in the fourth figure, another embodiment of the creative cushion washer. The cushion washer 22 includes a ring portion 222 and two retaining blocks 226 extending downward from the ring portion 222. The ring portion 222 is provided with a通 孔 224. The difference from the above embodiment is that the pair of blocks 226 form an angle of 90 ° on the circumference of the ring portion 222. Correspondingly, the slots on the fan frame receiving the blocks 226 are also distributed at 90 ° on the circumference of the perforation. The fifth figure shows another embodiment of the cooling fan mounting device having a shock-absorbing structure. The upper and lower flanges 314 and 313 of the fan frame 310 are substantially square. The four corners of the upper flange 314 are substantially right angles, and each corner is provided with a perforation 315 and a slot 316 adjacent to the perforation 315. Corresponding to a female perforation 315, there is no buffer ring 320. Each buffer ring 320 includes an upper ring portion 321, a wall portion 323 extending along the outer side of the upper ring portion 321, and a bend from the end of the wall portion 323. The lower annular portion 324, the upper and lower annular portions 321, 324 are respectively provided with a through hole 322, 3, and the diameter of both through holes 322, 325 is larger than the diameter of the through hole 315. The distance between the upper and lower ring portions 321 and 324 is approximately equal to or slightly smaller than the thickness of the upper flange 314. After assembly, the cushion washer 320 is elastically deformed to fix the cushion washer 32. On the upper flange 314. The ring portion 321 on the buffer washer 320 is further provided with a M269691 bump 326 extending in the direction of the downward ring portion 324. During assembly, the buffer ring 320 is elastically deformed to increase the distance between the upper and lower ring portions mi and 324. The upper flange 314 is sandwiched between the upper and lower ring portions 321 and 324 and raised. The block 326 is received in the slot 316, and finally the buffer washer 32 is deformed to install the buffer washer 32 on the fan frame 310. As shown in the sixth figure, after assembly, each buffer washer 32 ° is set at the corner of the upper flange 314, and the through holes 322 and 325 of the buffer washer 320 are communicated with the perforations 315. The upper ring portion 321 abuts the upper surface of the upper flange 314, and the lower ring portion 324 abuts the lower surface of the upper flange 314, so that the buffer washer 32 is restricted in the vertical direction. The bump 326 is accommodated in the slot 316 to restrict the buffer washer 32 from moving in the horizontal direction. When the fan frame 310 and the buffer washer 320 are mounted on a support, the ring portion 321 above the buffer washer 32 is pressed between the upper surface of the fan frame 31 and the support, so that the fan frame 31 It is not in direct contact with the support, and the vibration generated by the fan will not be transmitted to the support due to the blocking of the buffer 32 (), thereby reducing the vibration and the noise generated in the system. In this modified example, the δ upper ring portion 324 serves as the elastic buffer portion, and the wall portion 323 and the lower circle W321 serve as the positioning portions of the fixed buffer portion. In addition, the elastic buffering portion and the positioning portion on the other side of the flange 314 are not limited to the above-mentioned ring shape, and may have other shapes. When a fixing member such as a bolt is not used to fix the wind, the buffering portion and the positioning portion may not be included. Open through holes. In the above embodiment, the entire buffer ring is made of an elastic material, and it is understandable that only the elastic buffer portion to be pressed may be made of an elastic material. In summary, this creation complies with the requirements for new patents, and a patent application is filed in accordance with the law. However, the above is only a preferred embodiment of this case. For example, anyone who is familiar with the skills of this case will decorate her in Aiyiben M269691 = 神 _ 之 _, and cover the town of Shen_.
