## Title
Fixing structure for the faceplate ventilation screen of a power source supplier

## Abstract

A fixing structure for the faceplate ventilation screen of a power source supplier includes a faceplate body and at least one ventilation screen. The faceplate body has an inner side formed with at least two first extension portions protruding out vertically in the same direction, and the two first extension portions have their opposite inner sides respectively provided with a first position-limiting member extending oppositely at a location adjacent to the faceplate body. The first position-limiting members are parallel to the faceplate body, and a first gap is formed between the first position-limiting members and the faceplate body for receiving two ends of the ventilation screen. The first position-limiting members can be deformed by external force toward the faceplate body for firmly fixing the ventilation screen on the faceplate body.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a fixing structure, particularly to one for the faceplate ventilation screen of a power source supplier.
2. Description of the Prior Art
In general, when a power source supplier carries out AC and DC power source conversion, operation of the electronic parts in the power source supplier will produce high temperature. To prevent the electronic parts of a power source supplier from damaged by excessively high temperature produced in the power source supplier, the power source supplier has its interior installed with cooling fins and heat-dissipating fans and its peripheral side bored with at least one opening assembled thereon with a ventilation screen for exhausting high temperature out of the power source supplier through circulation, able to enhance effect of heat dissipation for the power source supplier. The ventilation screen of a conventional power source supplier is threadably locked on the casing or on the faceplate of the power source supplier; therefore, the casing and the ventilation screen of the power source supplier must be bored with a plurality of locking holes so that the ventilation screen can be firmly fixed on the casing of the power source supplier by means of locking members, thus spoiling esthetic appearance of a power source supplier and complicated in installation of the ventilation screen.
SUMMARY OF THE INVENTION
The objective of this invention is to offer a fixing structure for the faceplate ventilation screen of a power source supplier, facilitating a user to simplify a process of installing a ventilation screen and having effect of beautifying the external looks of a power source supplier.
The fixing structure for the faceplate ventilation screen of a power source supplier includes a faceplate body and at least one ventilation screen. The faceplate has an inner side formed with at least two first extension portions protruding out vertically in the same direction, and the first extension portions have their opposite inner sides respectively provided with a first position-limiting member extending oppositely at a location adjacent to the faceplate body. The first position-limiting members are parallel to the faceplate body, and a reserved first gap is formed between the position-limiting members and the faceplate body for receiving two ends of the ventilation screen.
Thus, the first position-limiting members can be deformed by external force toward the faceplate body for firmly fixing the ventilation screen on the faceplate body, enabling a user to simplify the process of installing the ventilation screen and attaining effect of beautifying the external looks of a power source supplier.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
A first preferred embodiment of a fixing structure for the faceplate ventilation screen of a power source supplier in the present invention, as shown in FIGS. 1-3, includes a faceplate body 10 and at least one ventilation screen 20 as main components combined together.
The faceplate body 10 rectangular-shaped is bored with two rectangular ventilation openings, having two ends respectively defined to be an upper end 12 and a lower end 13. The upper end 12 and the lower end 13 of the faceplate body 10 are respectively formed with a first extension portion 14 protruding out vertically in the same direction and located at the inner side of the faceplate body 10, and the two first extension portions 14 have their opposite inner sides respectively provided with a first position-limiting member 15 extending oppositely at a location adjacent to the faceplate body 10. The two first position-limiting members 15 are parallel to the faceplate body 10, and a reserved first gap 16 is formed between the first position-limiting members 15 and the faceplate body 10. In this preferred embodiment, the faceplate body 10, the first extension portions 14 and the first position-limiting members 15 are integrally made of aluminum squeezed in shape. The first position-limiting member 15 is a first elongated rib 151 that has a thickness less than the faceplate body 10 and can be pressed by external force to be deformed toward the faceplate body 10.
In this preferred embodiment, the faceplate body 10 of the power source supplier is provided with two ventilation screens 20 rectangular-shaped, and two ends of each ventilation screen 20 can be received in the opposite first gaps 16 to have the ventilation screen 20 correspondingly positioned at one of the rectangular ventilation openings 11.
In assembling, referring to FIG. 4, after the two ventilation screens 20 respectively have their opposite ends received in the first gaps 16 of the faceplate body 10, and the two ventilation screens 20 are respectively adjusted to be positioned at each of the rectangular ventilation openings 11, apply an external force to the first elongated ribs 151, which is then deformed toward the faceplate body 10 and pressed on the ventilation screens 20, thus firmly fixing the ventilation screens 20 on the faceplate body 10.
A second preferred embodiment of a fixing structure for the faceplate ventilating screen of a power source supplier in the present invention, as shown in FIGS. 5-8, has almost the same structure as that of the first preferred embodiment, except that the faceplate body 10 is a comparatively large-sized faceplate (a 2UH-specification faceplate) and formed additionally with a second extension portion 17 protruding out vertically between the two first extension portions 14 and located at an intermediate portion of the faceplate body 10. The second extension portion 17 has two opposite sides respectively provided with a second position-limiting member 18 protruding upward and parallel to the faceplate 10, with a reserved second gap 19 formed between the second position-limiting members 18 and the faceplate 10 for receiving two ends of a ventilation screen 20, as shown in FIG. 8. In this preferred embodiment, the second position-limiting member 18 is a second elongated rib 181 made of aluminum. After two ends of the ventilation screen 20 are respectively received in the first gap 16 and the second gap 19, the first elongated rib 151 and the second elongated rib 181 are pushed by external force to be deformed toward the faceplate body 10 and pressed on the ventilation screens 20, thus securing stably the ventilation screens 20 on the faceplate body 10.
To sum up, the fixing structure for the faceplate ventilation screen of a power source supplier of this invention is to have two ends of the ventilation screen received in the gaps formed between the faceplate body and the position-limiting members. Then, the position-limiting members are pressed by external force to be deformed toward the faceplate body and pushed on the ventilation screen to firmly fix the ventilation screen on the faceplate body, simplifying a process of assembling the ventilation screen and attaining effect of beautifying the external appearance of the power source supplier.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
