DETAILED DESCRIPTION OF THE INVENTION

(11) With reference to FIGS. 1 to 9 of a retractable structure for an air-conditioning vent in accordance with the present invention, the vent includes a main body 1 mounted onto a wall, and the main body 1 has an installing hole 11, and the vane 2 corresponding to the installing hole 11 is installed onto the main body 1 through the retractable mechanism 3.

(12) The retractable mechanism 3 comprises: a bottom plate 31, riveted on the main body 1; a connecting base 32, being perpendicular to the bottom plate 31, and having two latch plates 321 installed at a middle portion of the connecting base 32, and a spread-open surface (not numbered) of the connecting base 32 being in a T-shape, and the middle portion of the connecting base 32 being a flat structure, and the cross-section of the remaining portion of the connecting base 32 is in an arc shape (not shown).

(13) The bottom plate 31 and the connecting base 32 constitute a connecting plate of this preferred embodiment.

(14) The bracket 33 includes a flat middle portion 331, and a first bracket portion 332 and a second bracket portion 333 disposed on both sides of the middle portion 331 respectively. Both first bracket portion 332 and second bracket portion 333 are protruded outwardly and bent inwardly to form an external protruding corner structure. In addition, both first bracket portion 332 and second bracket portion 333 have a latch hole 334. The two latch plates 321 are passed through the corresponding latch holes 334 and then latched to the middle portion 331 of the bracket 33, so that the bracket 33 can be connected to the connecting base 32. In this preferred embodiment, the middle portion 331 of the bracket 33 further includes two cutouts 335 disposed symmetrically with each other, and the connecting base has two limit bumps 322 corresponding to the two cutouts 335. With a combination of the bumps 322 and the cutouts 335, the bracket 33 can be fixed onto the connecting base more securely.

(15) In this preferred embodiment, there are three retractable mechanisms 3 distributed uniformly along the periphery defining the installing hole 11. Correspondingly, the vane has four corresponding plug holes 21.

(16) The operating principle of the retractable structure is described as follows:

(17) During transportation, the vane 2 is pressed inwardly, so that the plug hole 21 is situated at the middle portion 331 of the bracket 33. With the position limited by first bracket portion 332 and the second bracket portion 333, the vane 2 can be limited securely between the first bracket portion 332 and the second bracket portion 333 to prevent damages caused by vibrations occurred in the transportation process.

(18) During use, the vane 2 is pulled and stretched outward, such that the first bracket portion 332 is compressed and squeezed by an edge of the plug hole 21 during the pulling and stretching process, and the external protruding corner is deformed, such that the plug hole 21 is disposed across the external side of the corner of the first bracket portion 332. Now, the protrusions on both edges of the connecting base 32 can be abutted and stopped by the edge of the plug hole 21, and the plug hole 21 is stopped at the corner of the first bracket portion 332.

(19) After the vent is installed, users can repeat the aforementioned operation to retract the vane 2 into the installing hole 11 of the main body 1 or stretch the vane 2 from the interior of the main body 1 to the outside. The retracting or stretching operation is very convenient and has a good hand feel.

(20) In summation of the description above, the present invention improves over the prior art and complies with the patent application requirements, and thus is duly filed for patent application.
