Description

Fan clamping structure

A fan clamping structure, in particular, a fan clamping structure that provides a fan and other structures to achieve a fast plugging and fixing effect.

The cooling fan is the most common and effective cooling unit that forcibly guides the airflow to dissipate the system cabinets, personal computers or electronic products. However, the cooling fan cannot be directly locked on each unit, usually through a fastener or on the fan itself. Four corners fix the fan by screw lock by threading screws. There are multiple fans in series or in parallel in the system cabinet, and because the fans run continuously for 24 hours to provide the cooling effect of the system cabinet, the phenomenon of failure will occur relatively, and the fan must be replaced. If The fan is fixed to the system cabinet by a screw lock, and the replacement of the fan is more complicated and time-consuming. Therefore, those skilled in the art design a series assembly 6 combined with the fan in series, which can be provided to the user. For the convenience of quick fan replacement, the tandem assembly 6 has a body 61, and the body 61 is provided with a hand buckle 62, the hand buckle 62 is provided with a pressing member 63, and the side of the body 61 is pressable and riveted A hook 64 with a hook 641 at one end, and one end of the pressing member 63 is connected to the end of the hook 64 without the hook 641, and is pressed by fingers through the series assembly 61 , The down-and-down operation of the hook portion 641 of the hook fastener 64 to hook or release is used as a quick-release assembly method, but the quick-release structure of the tandem assembly 6 has a plurality of small metal components (pressing piece 63 and hooking piece 64 ) Is composed of each other and must be fixed to the kit by riveting, which not only is inconvenient to assemble the kit, but also increases the manufacturing cost of the fan. Therefore, how to solve the problems derived from the prior art is the first priority for the industry. The purpose.

Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide an integrated quick-release structure, which effectively provides a structure in which series or parallel fans can be quickly inserted and removed in the system chassis or cabinet. In order to achieve the above-mentioned objective, the present invention provides a fan clamping structure, which is used in series and parallel connection with the fan to provide the fan and other structures for fast plugging and fixing. The fan clamping structure includes: a frame body; The frame body has a first end and a second end, the frame body has a hollow channel, the first end is connected to a fan, the frame body has a first side and a second side, so The first side extends a snap-fit elastic sheet, the surface of the snap-fit spring sheet has a snap portion, and the second side has a finger snap portion, thereby providing a fan and other structures to achieve a fast plug-in fixing effect. Through the integrated structure of the present invention, the manufacturing cost can be greatly reduced and the fans connected to each other can be quickly plugged in and fixedly combined.

The outer edge of the frame body 1 It has a first side 14 and a second side 15. The first side 14 extends a locking elastic piece 141. The surface of the locking elastic piece 141 has a locking portion 142 formed by the locking elastic piece 141 The surface is convex, and the second side 15 has a finger buckle 151, so as to provide the fan 2 and other structures to achieve a fast plug-in fixing effect. The frame body 1 has a through hole 16 in each of the four corners. Only one end of the locking elastic piece 141 is connected to the first side 14 of the frame body 1, and the left and right sides of the locking elastic piece 141 have a first gap 143 and a second gap 144. The finger buckle portion 151 is formed by extending the edge of the second side 15 and has a vertical extension section 1511 and a U-shaped extension section 1512. The vertical extension section 1511 and the U-shaped extension section 1512 are connected to each other. Please refer to Figure 3, which is a three-dimensional schematic diagram of the second embodiment of the fan fixing structure of the present invention. The difference between this embodiment and the aforementioned first embodiment is that the first end of this embodiment is connected to the air inlet side of the fan 2, and a grid body 3 is provided between the fan 2 and the first end 11. Please refer to Figure 4, which is a three-dimensional schematic diagram of the third embodiment of the fan clamping structure of the present invention. As shown in the figure, part of the structure of this embodiment is the same as that of the aforementioned first embodiment. The difference between this embodiment and the aforementioned first embodiment is that there is a connection port 4 which is connected to the opposite end of the fan 2 and the frame body 1. Please refer to Figure 5, which is a three-dimensional schematic diagram of the fourth embodiment of the fan fixing structure of the present invention. The difference between this embodiment and the aforementioned first embodiment is that the second side 15 also has a locking elastic piece 152, and the surface of the locking elastic piece 152 has a buckle portion 153. The left and right sides of the locking elastic piece 152 There is a third gap 154 and a fourth gap 155 between the second side 15. Please refer to Figure 6, which is a schematic diagram of the action of the fan clamping structure of the present invention. As shown in the figure, this embodiment mainly discloses how the fan clamping structure is combined with the fan 2 and fixed together on a server chassis 5 for quick insertion. To pull out, first, one end of the fan 2 is first connected to the port 4, and the other end of the fan 2 is connected to the frame body 1. The port 4 is connected to a terminal on the server chassis 5 (not shown in the figure). Show) is plugged for electrical connection, and the fan 2 is engaged with the side wall of the server chassis 5 through the surface protrusion of the buckle portion 142 on the surface of the clamping spring 141 of the frame body 1, and when the fan 2 When disassembling, use one finger to hook on the finger buckle 151 of the second side 15 of the frame body 1, and the other finger to pull the movable snap spring 141 to make the snap on the surface 142 is separated from the small recessed hole or small pit on the side wall of the server chassis 5 that engages with it, so that the fan 2 can be pulled out of the server chassis 5 for unplugging operation. The invention mainly provides the work that the series or parallel fan and the server case can be quickly swapped and plugged, and the frame body component is simply integrated and designed to greatly reduce the manufacturing cost.
