The supporting plate 3 is rotatably connected with the test bed body 1, and the supporting plate 3 is used for supporting the vehicle-mounted charger 7.
A supporting block 31 is fixed on the upper side of the supporting plate 3, the limit screw 4 is in threaded connection with the supporting block 31, and a plurality of limit screws 4 are arranged; after the vehicle-mounted charger 7 is placed on the supporting plate 3, the limiting screws 4 are distributed along the circumferential direction of the vehicle-mounted charger 7, and the limiting screws 4 can be matched with each other to clamp and fix the vehicle-mounted charger 7.
When the vehicle-mounted charger 7 is used, after a worker places the vehicle-mounted charger 7 on the support plate 3, the air holes 71 on the vehicle-mounted charger 7 can face any direction (the front-back left-right direction shown in fig. 1), and the direction of the air holes 71 on the vehicle-mounted charger 7 can be adjusted only by rotating the support plate 3 in the follow-up process, so that the air hole connector 21 and the air holes 71 on the vehicle-mounted charger 7 can be conveniently butted together after the air hole connector 21 is moved; in the process of rotating the supporting disc 3, the bottom of the vehicle-mounted charger 7 does not need to move relative to the supporting disc 3, so that the bottom of the shell of the vehicle-mounted charger 7 is not easy to wear, and the labor intensity of workers is low.
It should be noted that, when there are two air holes 71 of the vehicle-mounted charger 7, for example, the air guide mechanism 2 may also include two air hole connectors 21, during the test, two air hole connectors 21 may be first connected to one air hole 71, then one air hole connector 21 is connected to the air tightness tester, and the other air hole connector 21 is blocked, and then the air tightness test may be performed by the air tightness tester.
The main components and the principle of action of the air-tight test stand of the vehicle-mounted charger 7 are described above in general, and the air-tight test stand of the vehicle-mounted charger 7 will be described in more detail below.
In order to avoid damage to the housing of the vehicle-mounted charger 7 caused by the end of the limit screw 4 when the limit screw 4 is screwed down, a rubber pad 41 may be fixed at one end of the limit screw 4 facing the vehicle-mounted charger 7.
In order to facilitate maintaining the support plate 3 in the current position after rotating the support plate 3, the in-vehicle charger 7 air-tight test stand may further include a rotation limiting mechanism 5 for limiting the rotation of the support plate 3.
Specifically, the rotation limiting mechanism 5 may mainly include: a first support plate 51, a compression lever 52 and a tension spring 53; the first support plate 51 is fixed on the test stand body 1; the compression bar 52 is hinged with the first support plate 51; one end of a tension spring 53 is connected to the compression rod 52, and the other end is connected to the first support plate 51, and the tension spring 53 is used to directly or indirectly press one end of the compression rod 52 down on the support plate 3. One end of the pressing lever 52 can be directly or indirectly pressed down on the support plate 3 by the tension spring 53, thereby restricting the rotation of the support plate 3 by friction force; when the support plate 3 is required to be rotated, a worker can separate the pressing lever 52 from the support plate 3 by pressing down the right end (left-right direction shown in fig. 3) of the pressing lever 52, so that the support plate 3 can be rotated.
In the present embodiment, preferably, one end of the pressing lever 52 is indirectly pressed down on the support plate 3, and specifically, the rotation limiting mechanism 5 may further include a pressing block 54 capable of contacting the support plate 3, the pressing block 54 being hinged at one end of the pressing lever 52. The base of the press block 54 and the support disc 3 may have a larger contact area, which helps to better restrict the rotation of the support disc 3 when the press block 54 and the support disc 3 are in contact.
The rotation limiting mechanism 5 is only a preferred embodiment, and the rotation limiting mechanism 5 may be other structures as long as the above purpose can be achieved, and this embodiment is not limited to the above one.

The screw 24 is rotated to move the air guide block 26 and the air hole joint 21 laterally so as to facilitate the butt joint or separation of the air hole joint 21 and the air hole 71.
Because the positions of the air holes 71 of the vehicle-mounted chargers 7 of different models are different, when the bracket 22 and the second support plate 23 are both fixedly arranged, the air hole connector 21 can only move transversely, so that the air hole connector 21 is inconvenient to be in butt joint with the air holes 71 of the vehicle-mounted chargers 7 of different models.
