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. 1-2, the present invention provides a technical solution: a conveniently-installed isolation AC-DC power module comprises a power module 1 and an installation platform 5, wherein two symmetrically-arranged support plates 4 are welded on the installation platform 5, fixing grooves 401 are formed in the support plates 4, a fixing block 6 is fixedly connected to the bottom of the power module 1, a rotating rod 10 is rotatably installed between the fixing blocks 6 through a bearing, an elliptic cylinder 3 is sleeved on the outer side of the rotating rod 10 and is driven to rotate through rotation of the rotating rod 10, the elliptic cylinder 3 is located between fixing plates 8 on two sides, springs 7 are connected to two sides of the fixing block 6, a fixing plate 8 with an L-shaped vertical cross section is elastically connected to the free end of each spring 7, the horizontal end of each fixing plate 8 is inserted into the corresponding fixing groove 401, the horizontal end of each fixing plate 8 is extruded through the long shaft end of the elliptic cylinder 3 and is inserted into the corresponding fixing groove 401, each spring 7 is stretched, and the connection between the fixing plate 8, the major axis end through cylindroid 3 rotates vertical end, and fixed plate 8 loses the restriction, and under spring 7's answer effect, the horizontal end of fixed plate 8 breaks away from fixed slot 401 automatically to just, accomplish power module 1 and mounting platform 5's separation, simple structure, convenient operation, and current bolted connection's screw thread problem of inefficacy can not appear.

Specifically, as shown in fig. 1, the distance between the power module 1 and the mounting platform 5 is greater than the length of the major axis of the section ellipse of the elliptic cylinder 3, so as to ensure that the elliptic cylinder 3 does not interfere with the rotation.

Specifically, as shown in fig. 1-2, a rubber pad 9 is bonded to the outer side of the horizontal end of the fixing plate 8, so as to improve the friction between the horizontal end of the fixing plate 8 and the fixing groove 401, thereby improving the connection tightness between the fixing plate 8 and the supporting plate 4 and improving the installation stability of the power module 1 on the installation platform 5.

Specifically, as shown in fig. 1, the two sides of the supporting plate 4 are provided with a limiting groove 701, and when the long axis of the cross section of the elliptic cylinder 3 is horizontal, the rotation of the elliptic cylinder 3 is limited by the clamping connection between the two sides of the elliptic cylinder 3 and the limiting groove 701, so that the connection stability between the fixing plate 8 and the fixing groove 401 is ensured.
