Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a singly organize output power supply ware, including supplier casing 1, heat dissipation fan 13 is installed at the top of supplier casing 1, both sides of supplier casing 1 all are equipped with bleeder vent 14 and go on the apron 2 that covers to bleeder vent 14, bleeder vent 14 is seted up on the outer wall of supplier casing 1, apron 2 rotates through the pivot with supplier casing 1 and is connected, the spacing groove 12 has on the apron 2, have on the supplier casing 1 and act on spacing groove 12, carry out spacing locating part to apron 2.

Specifically, as shown in fig. 1, fig. 2 and fig. 3, the limiting member includes a protruding block 6 fixed on the top of the supplier housing 1, an L-shaped limiting arm 10 penetrates through the protruding block 6, the limiting arm 10 is in clearance fit with the protruding block 6, a limiting pin 11 adapted to a limiting groove 12 is provided on the limiting arm 10, a flange 4 is fixed at the end of the limiting arm 10, a spring 5 is provided between the flange 4 and the protruding block 6, the spring 5 is sleeved outside the limiting arm 10, two ends of the spring 5 are respectively abutted against the flange 4 and the protruding block 6, the limiting pin 11 is engaged with the limiting groove 12 under the action of the spring 5, the cover plate 2 can be positioned, and the cover plate 2 is prevented from rotating.
