Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, 2 and 4, a computer power supply box convenient to dismantle, include box 1, be used for closing box 1's case lid 2 and all set up at the inside PCB board 3 and dwang 4 of box 1, the one end of dwang 4 is rotated with the diapire of box 1 and is connected, dwang 4 is formed with first fixture block 41 and second fixture block 42 along its radial protrusion, PCB board 3 is equipped with the first through-hole 31 that is used for supplying dwang 4 to pass and is used for supplying the first groove 32 of stepping down that first fixture block 41 passed, when first fixture block 41 misplaces with first groove 32 of stepping down, first fixture block 41 with PCB board 3 joint, case lid 2 is equipped with the second through-hole 21 that supplies dwang 4 to pass and is used for the second groove 22 of stepping down that second fixture block 42 passed, when second fixture block 42 misplaces with second groove 22, second fixture block 42 with case lid 2 joint.

When the computer power supply box is assembled, the PCB 3 is placed into the box body 1, the rotating rod 4 and the first clamping block 41 respectively penetrate through the first through hole 31 and the first abdicating groove 32, the box body 1 is sealed by the box cover 2, the rotating rod 4 and the second clamping block 42 respectively penetrate through the second through hole 21 and the second abdicating groove 22, then the rotating rod 4 is rotated to enable the first clamping block 41 to be dislocated with the first abdicating groove 32, the second clamping block 42 to be dislocated with the second abdicating groove 22, so that the first clamping block 41 is clamped with the PCB 3, the second clamping block 42 is clamped with the box cover 2, and relative fixation between the PCB 3 and the box body 1 and between the box cover 2 and the box body 1 is realized. When the computer power box needs to be disassembled, the box cover 2 and the PCB board 3 can be disassembled quickly by rotating the rotating rod 4 to align the first latch 41 with the first receding groove 32 and align the second latch 42 with the second receding groove 22.

As shown in fig. 3 and 4, the first latch 41 is provided with a first elastic pad 43 for abutting against the PCB 3, and the second latch 42 is provided with a second elastic pad 44 for abutting against the cover 2. Because of the precision problem, when the first fixture block 41 is dislocated from the first receding groove 32, there is a gap between the first fixture block 41 and the PCB 3, and when the computer power box vibrates, the first fixture block 41 and the PCB 3 may collide with each other to cause abnormal sound and abrasion, so in some embodiments, the first elastic pad 43 is disposed to fill the gap between the first fixture block 41 and the PCB 3, thereby reducing the abnormal sound and abrasion.

As shown in fig. 1 to 4, one end of the rotating lever 4 is provided with a flat portion 5, and the cross section of the flat portion 5 is rectangular. In the conventional design, the rotating rod 4 is mostly cylindrical, and when the user twists the rotating rod 4, the user slips easily along the circumferential direction of the rotating rod 4. In some embodiments, therefore, the flat portion 5 is provided for grasping by the user to reduce the occurrence of slippage.

When the length of the flat portion 5 is too short, the user cannot easily grip the flat portion, but when the length of the flat portion 5 is too long, the user occupies a large space. Therefore, in some embodiments, as shown in fig. 1 and 2, the rotating rod 4 is provided with a sliding slot 45, and the flat part 5 is slidably connected with the sliding slot 45 so as to enable the flat part 5 to be stretched.

After the flat part 5 is retracted into the sliding groove 45, it is difficult for the user to take out the flat part 5, so in some embodiments, as shown in fig. 3 and 4, one end of the flat part 5 close to the box body 1 is slidably connected with the sliding groove 45, and a lifting groove 51 is arranged on the periphery of one end of the flat part 5 far from the box body 1, so that the user can stretch the finger tip into the lifting groove 51 and pull out the flat part 5.

As shown in fig. 4, the cross-sectional area of the case cover 2 is larger than the cross-sectional area of the opening of the case body 1, and the opening can limit the case cover 2, so that the case cover 2 does not fall into the inside of the case body 1.

As shown in fig. 1, the corners of the case cover 2 are provided with rounded corners 23, which effectively prevent the corners of the case cover 2 from scratching a user.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
