DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Please refer to FIGS. 1 and 2. FIG. 1 is a perspective view of a first embodiment of the fan engagement structure of the present invention. FIG. 2 is a perspective view of the first embodiment of the fan engagement structure of the present invention. The fan engagement structure of the present invention is for the fan to quickly and securely plug into or extract out of another structure. The fan engagement structure of the present invention includes a frame main body 1.

[0018] The frame main body 1 has a first end 11 and a second end 12 respectively positioned at a front end and a rear end of the frame main body 1. The frame main body 1 has an internal hollow passage 13 in communication with the first and second ends 11, 12. The first end 11 is mated with a fan 2. (In this embodiment, the fan is, but not limited to, a series fan for illustration purposes.) The outer periphery of the frame main body 1 has a first side 14 and a second side 15. An engagement elastic plate 141 extends from the first side 14. The surface of the engagement elastic plate 141 has a latch section 142 raised from the surface of the engagement elastic plate 141. The second side 15 has a finger latch section 151. Accordingly, the fan 2 can be quickly and securely plugged into or extracted out of another structure. Each of four corners of the frame main body 1 is formed with a through hole 16.

[0019] Only one end of the engagement elastic plate 141 is connected with the first side 14 of the frame main body 1. The left and right sides of the engagement elastic plate 141 respectively have a first gap 143 and a second gap 144.

[0020] The finger latch section 151 extends from the edge of the second side 15 and has a perpendicularly extending section 1511 and a U-shaped extending section 1512. The perpendicularly extending section 1511 and the U-shaped extending section 1512 are connected with each other.

[0021] Please now refer to FIG. 3, which is a perspective view of a second embodiment of the fan engagement structure of the present invention. The second embodiment is partially identical to the first embodiment in structure and thus will not be redundantly described hereinafter. The second embodiment is different from the first embodiment in that the first end 11 is mated with the wind outlet side of the fan 2 and a mesh body 3 is disposed between the fan 2 and the first end 11.

[0022] Please now refer to FIG. 4, which is a perspective view of a third embodiment of the fan engagement structure of the present invention. The third embodiment is partially identical to the first embodiment in structure and thus will not be redundantly described hereinafter. The third embodiment is different from the first embodiment in that the third embodiment further has a connection port end 4 mated with one end of the fan 2 opposite to the frame main body 1.

[0023] Please now refer to FIG. 5, which is a perspective view of a fourth embodiment of the fan engagement structure of the present invention. The fourth embodiment is partially identical to the first embodiment in structure and thus will not be redundantly described hereinafter. The fourth embodiment is different from the first embodiment in that the second side 15 also has an engagement elastic plate 152. The surface of the engagement elastic plate 152 has a latch section 153. A third gap 154 and a fourth gap 155 are formed between the left and right sides of the engagement elastic plate 152 and the second side 15.

[0024] Please now refer to FIG. 6, which is a perspective view showing the operation of the fan engagement structure of the present invention. As shown in the drawing, the way how the fan engagement structure is connected with the fan 2 and together secured to a server chassis 5 for quick plugging and extraction. First, one end of the fan 2 is mated with the connection port end 4. The other end of the fan 2 is mated with the frame main body 1. The connection port end 4 is plugged into a terminal (not shown) on the server chassis 5 to electrically connect therewith. The latch section 142 raised from the surface of the engagement elastic plate 141 of the frame main body 1 is securely engaged with a small dent or a small pit on a sidewall of the server chassis 5 to connect the fan 2 with the server chassis 5. When detaching the fan 2, a finger hooks the finger latch section 151 of the second side 15 of the frame main body 1 and another finger pries the movable engagement elastic plate 141. Accordingly, the latch section 142 of the surface of the engagement elastic plate 141 is separated from the small dent or small pit of the sidewall of the server chassis 5. Therefore, the fan 2 can be drawn and extracted out of the server chassis 5.

[0025] The present invention is mainly for a series fan or a parallel fan to quickly plug into or extract out of a server chassis and replaced. In addition, the components of the frame main body 1 are simplified and integrated to greatly lower the manufacturing cost.

[0026] The present invention has been described with the above embodiments thereof and it is understood that many changes and modifications in such as the form or layout pattern or practicing step of the above embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
