Example 1

Referring to fig. 1-6, a sealing device for an inverter comprises a first fixing member 1, a second fixing member 2, a first connecting member 6 and a second connecting member 7, wherein the bottom of the first fixing member 1 is movably sleeved with the bottom of the second fixing member 2, the first connecting member 6 is movably sleeved with the first fixing member 1, the second connecting member 7 is movably sleeved with the second fixing member 2, the first connecting member 6 is movably connected with the second connecting member 7, the first fixing member 1 and the second fixing member 2 are both provided with a female hole 11, the first connecting member 6 and the second connecting member 7 are both provided with a male hole 61, and the female hole 11 is matched with the male hole 61.

The utility model discloses in, the both sides of first mounting 1 are equipped with bail 4, and are connected with shell fragment 5 between bail 4 and the 1 surface of first mounting.

The utility model discloses in, behind the staple 4 compression shell fragment 5, and the whole body radius of staple 4 is not more than the radius of first mounting 1.

The utility model discloses in, install spring 3 between first mounting 1 and the 2 junctions of second mounting.

The utility model discloses in, second connecting piece 7 through connection has threaded rod 8, and second connecting piece 7 passes through threaded rod 8 and the bottom threaded connection of first connecting piece 6.

In the utility model, the top of the threaded rod 8 is provided with a cross hole 81 for rotation.

The working principle is as follows: during the use, select suitable mounting according to the trompil size on the dc-to-ac converter, the mounting forms for first mounting 1 and the combination of second mounting 2, twist the trompil hard and withhold the mounting, after bail 4 on first mounting 1 passes the trompil, outside flick under the effect of shell fragment 5 for first mounting 1 blocks the inside border of trompil firmly, later reuse power outside pulling second mounting 2, spring 3 compresses under the effect of pulling force, the border of trompil is blocked to bail 4 on the second mounting 2 until, thereby reach the fixed purpose of connection. And then, inserting the first connecting piece 6 and the second connecting piece 7 into the first fixing piece 1 and the second fixing piece 2 respectively, connecting the first fixing piece 1 and the second fixing piece 2 by rotating the threaded rod 8, adjusting the threaded rod 8 to ensure that the female hole 11 on the first fixing piece 1 is not superposed with the female hole 61 on the first connecting piece 6 when the female hole 11 on the second fixing piece 2 is superposed with the female hole 61 on the second connecting piece 7, namely, the female hole 61 on one side is communicated with the female hole 11, and the female hole 11 on the other side is not communicated with the female hole 61. When the internal pressure of the inverter is slightly greater than the external environment pressure, under the action of the pressure difference, the first connecting piece 6 moves outwards, so that the sub-hole 61 on the first connecting piece 6 is communicated with the female hole 11 on the first fixing piece 1, and the internal space of the inverter is communicated with the inside of the connecting piece, on one hand, the effective space in the inverter is increased because the first connecting piece 6 moves outwards, and on the other hand, the internal space of the inverter is communicated with the inside of the connecting piece, so that the internal pressure of the inverter is reduced.
