Power supply chassis having guiding and fixing effect

Abstract

A power supply chassis has at least one accommodating slot therein. Two side walls of the accommodating slot of the power supply chassis are provided with a first left guiding and fixing block and a first right guiding and fixing block. The guiding and fixing blocks have a first left guiding bevel and a first right guiding bevel facing a front side of the accommodating slot, a first left fixing plane and a first right fixing plane corresponding in position to the middle of the accommodating slot. When a power supply is placed into the accommodating slot, the first left guiding bevel and the first right guiding bevel guide the power supply to a middle position of the accommodating slot, and the power supply is clamped by the first left fixing plane and the first right fixing plane to enhance the stability of the power supply.

The first right fixing plane 22 is provided with two screw holes 23 for fixing the first right guiding and fixing block 20 to the right side wall of the accommodating slot 101 by means of screws. When the power supply 200 is disposed in the accommodating slot 101, the first right fixing plane 22 is located at a position where the back plate 203 and the bottom plate 204 of the power supply 200 are connected to each other.

(10) The second left guiding and fixing block 30 is disposed on the left side wall of the accommodating slot 101 and located at a front position of the accommodating slot 101. The second left guiding and fixing block 30 is made of rubber having an insulating function. The second left guiding and fixing block 30 has a second left guiding bevel 31 facing the front side of the accommodating slot 101. The second left guiding bevel 31 extends toward the front side of the accommodating slot 101. The second left guiding bevel 31 is inclined from right to left. The second left guiding and fixing block 30 has a second left fixing plane 32 corresponding to the middle position of the accommodating slot 101. The second left fixing plane 32 is provided with two screw holes 33 for fixing the second left guiding and fixing block 30 to the left side wall of the accommodating slot 101 by means of screws. When the power supply 200 is disposed in the accommodating slot 101, the second left fixing plane 32 is located at a position corresponding to the bottom plate 204 of the power supply 200.

(11) The second right guiding and fixing block 40 is disposed on the right side wall of the accommodating slot 101 and corresponds to the second left guiding and fixing block 30. The second right guiding and fixing block 40 is made of rubber having an insulating function. The second right guiding and fixing block 40 has a second right guiding bevel 41 facing the front side of the accommodating slot 101. The second right guiding bevel 41 extends toward the front side of the accommodating slot 101. The second right guiding bevel 41 is inclined from left to right. The second right guiding and fixing block 40 has a second right fixing plane 42 corresponding to the second left fixing plane 32. The second right fixing plane 42 is provided with two screw holes 43 for fixing the second right guiding and fixing block 40 to the right side wall of the accommodating slot 101 by means of screws. When the power supply 200 is disposed in the accommodating slot 101, the second right fixing plane 42 is located at a position corresponding to the bottom plate 204 of the power supply 200.

(12) Please refer to FIG. 4 and FIG. 5 again. First, when the power supply 200 is placed into the accommodating slot 101 of the power supply chassis 100, the user only needs to push the power supply 200 toward the accommodating slot 101. The corners of the back plate 203 of the power supply 200 are moved along the second left guiding bevel 31 and the second right guiding bevel 41 in the front position of the accommodating slot 101, and the power supply 200 is guided to the middle position of the accommodating slot 101. The left side plate 201 and the right side plate 202 at both sides of the power supply 200 abut against the second left fixing plane 32 and the second right fixing plane 42, and the second left fixing plane 32 and the second right fixing plane 42 are located a position corresponding to the bottom plate 204. Then, the power supply 200 is continuously pushed into the accommodating slot 101. The corners of the back plate 203 of the power supply 200 are moved along the first left guiding bevel 11 and the first right guiding bevel 21 in the rear position of the accommodating slot 101, and the power supply 200 is guided to the middle position of the accommodating slot 101. The left side plate 201 and the right side plate 202 at both sides of the power supply 200 abut against the first left fixing plane 12 and the first right fixing plane 22, and the first left fixing plane 12 and the first right fixing plane 22 are located a position where the back plate 203 and the bottom plate 204 of the power supply 200 are connected to each other. Therefore, the left side plate 201 and the right side plate 202 at both sides of the power supply 200 are clamped by the first left fixing plane 12, the first right fixing plane 22, the second left fixing plane 32 and the second right fixing plane 42 by a simple structure, so that the power supply 200 does not move left and right in the accommodating slot 101 to enhance the stability of the power supply 200 in the accommodating slot 101.

(13) It is to be noted that the back plate 203 and the bottom plate 204 are supported by the abutting function between the left side plate 201 and the right side plate 202 respectively, so that the back plate 203 can abut against the first left fixing plane 12 and the first right fixing plane 22 to clamp the power supply 200. Besides, the bottom plate 204 is supported by the abutting function between the left side plate 201 and the right side plate 202 respectively, so that the bottom plate 204 can abut against the second left fixing plane 32 and the second right fixing plane 42 to clamp the power supply 200. The damage of the power supply 200 caused by the sway of the power supply chassis 100 can be avoided, and the stability of the power supply 200 in the accommodating slot 101 is further enhanced.

(14) It is worth mentioning that the second left guiding and fixing block 30 and the second right guiding and fixing block 40 in the front position of the accommodating slot 101 are made of a rubber material; the first left guiding and fixing block 10 and the first right guiding and position block 20 in the rear position of the accommodating slot 101 are made of an engineering plastic material. The rubber material is soft and elastic, and the engineering plastic material is relatively hard. Therefore, when the power supply 200 is placed into the accommodating slot 101, because the second left guiding and fixing block 30 and the second right guiding and fixing block 40 are softer in material and less resistant, the power supply 200 can be easily pushed into the accommodating slot 101. The material of the first left guiding and fixing block 10 and the first right guiding and fixing block 20 is relatively hard. Therefore, after the power supply 200 is positioned in the accommodating slot 101, the power supply 200 can be held by the first left guiding and fixing block 10 and the first right guiding and fixing block 20, so that the power supply 200 can be stably disposed in the accommodating slot 101 to improve convenience and stability.

(15) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
