Detailed Description
The present application is described in further detail below in conjunction with figures 1-4.
The embodiment of the application discloses a breather valve mounting structure for an inverter box.
Referring to fig. 1 and 2, the mounting structure of the breather valve 3 for the inverter case 1 includes a reducing ring 2 disposed on the inverter case 1, a mounting hole having the same size as the neck 22 of the reducing ring 2 is formed in the inverter case 1, the neck 22 of the reducing ring 2 passes through the mounting hole, the neck 22 of the reducing ring 2 is screwed with a nut 7, the nut 7 abuts against the inner wall of the inverter case 1, the breather valve 3 is located outside the inverter case 1 and screwed on the inner edge of the reducing ring 2, and the end 21 of the reducing ring 2 abuts against the outer wall of the inverter case 1.
Thus, the neck 22 of the reducing ring 2 is screwed with the nut 7 to fix the reducing ring 2 by the inverter case 1, and then the breather valve 3 is installed into the inner edge of the reducing ring 2 by rotating the breather valve 3. When the air tightness of the inverter box body 1 needs to be verified, a user rotates the air ventilation valve 3 to detach the air ventilation valve 3 from the diameter reduction ring 2, then the interface of the air tightness detection instrument is rotatably installed into the inner edge of the diameter reduction ring 2, air tightness detection is carried out after the air tightness detection instrument is installed, the interface of the air tightness detection instrument is rotated again after the detection is finished to detach the air tightness detection instrument from the diameter reduction ring 2, and the air ventilation valve 3 is rotated to reinstall the air ventilation valve 3 into the diameter reduction ring 2. The operation flow is simplified, the air tightness verification is carried out without the mode of disassembling the whole machine upper cover of the inverter by disassembling the ventilation valve 3, the interface of the air tightness detection instrument is directly rotated and connected into the diameter reduction ring 2, the air tightness can be verified, and the possibility that the air tightness error of the inverter is caused by the fact that the whole machine upper cover of the inverter is disassembled and assembled possibly has inconsistent installation is reduced. Because the inverter box 1 is thin wall, all can't join in marriage and beat the screw thread for the unable direct threaded connection of breather valve 3 is on inverter box 1, this application mode is through inserting reducing ring 2, has indirectly realized the threaded connection between box and the breather valve 3, has simplified the operation flow, has reduced when dismouting inverter complete machine upper cover probably has the inconsistent possibility that leads to the inverter gas tightness error of installation.
Referring to fig. 2, the end surface of the nut 7 facing the inner wall of the case is provided with a plurality of anti-slip ribs 71, and the anti-slip ribs 71 may be serrated, and the serrations may be angled, so that the nut 7 does not rotate in the direction of loosening the nut 7, and the plurality of anti-slip ribs 71 abut against the inner wall of the case. Therefore, the anti-slip rib 71 increases the frictional resistance between the nut 7 and the inner wall of the inverter case 1, thereby providing a better tightening effect for the nut 7, and reducing the possibility of loosening.
