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 heat of the system cabinet, personal computer 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.

A plurality of series or parallel fans are installed 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 work of replacing the fan is more complicated and time-consuming. Therefore, those skilled in the art design a series assembly 6 that combines the series with the fan, which can be provided to users. For the convenience of quick fan replacement, the series assembly 6 has a main body 61, and the main 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 main 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 member 64 to hook or release is used as a quick-release assembly method, but the quick-release structure of the series assembly 6 has a plurality of small metal components (pressing member 63 and hook member 64 ) Are composed of each other and must be fixed to the kit by riveting As a fix, not only the assembly of the kit is inconvenient, but also the manufacturing cost of the fan. Therefore, how to solve the problems derived from the prior art is the primary goal of the industry.

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 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, and the first end is connected to a fan. The frame body has a first side and a second side. The first side extends a snap-fit elastic piece, the surface of the snap-fit elastic piece has a snap portion, and the second side has a finger snap portion, thereby providing the fan and other structures to achieve the effect of fast plugging and fixing.

Through the integrated structure of the present invention, the manufacturing cost can be greatly reduced and the fans connected to each other can be fast-plugged and fixedly combined.

The above-mentioned objects and structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings.

Please refer to Figures 1 and 2, which are a perspective view of the first embodiment of the fan fastening structure of the present invention. As shown in the figure, the fan fastening structure of the present invention is used to provide fast plugging and fixing of fans and other structures. The fan fixing structure includes: a frame body 1; the frame body 1 has a first end 11 and a second end 12, and the first and second ends 11, 12 are separately arranged at the front and rear of the frame body 1. The frame body 1 has a hollow passage 13 connected to the first and second ends 11 and 12, and the first end 11 is connected to a fan 2 (in the embodiment of this case, a series fan is selected for illustration. But not limited to) butt joint, the outer edge of the frame body 1 has a first side 14 and a second side 15, the first side 14 extends a snap-fitting elastic piece 141, the surface of the locking-elastic piece 141 has a buckle part 142. The buckle portion 142 is protruded from the surface of the buckling elastic piece 141, and the second side 15 has a finger buckle portion 151, thereby providing the fan 2 and other structures to achieve a fast plug-in fixing effect. The frame body 1 The four corners each have a through hole 16.

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.
