Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a sealing nut for fixing an explosion-proof valve. Background Art

[0002] Installing an explosion-proof valve on the battery pack of new energy vehicles can prevent it from exploding due to excessive internal pressure during combustion. However, when installing, the explosion-proof valve is mostly directly plugged into the stud of the battery pack and fixed with a nut. However, traditional nuts do not have an additional locking function, which makes it difficult to seal the connection between the explosion-proof valve and the battery pack during operation, thereby reducing the reliability of the explosion-proof valve. In response to the above situation, technical innovation is carried out based on the existing sealing nuts for fixing the explosion-proof valve. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model uses a cross screwdriver to be inserted into the cross groove of the screw and rotated, thereby driving the anti-slip pad to move backward through the screw to fit tightly with the stud on the battery pack, thereby increasing the friction between the nut and the stud on the battery pack, thereby improving the installation stability of the nut, and effectively ensuring the connection strength and sealing between the explosion-proof valve and the battery pack;

A cross block 15 is fixed on the rear side of the disk 11, and a positioning rod 16 is evenly fixed on the rear side of the connecting disk 11. The positioning rods 16 are evenly distributed on the outer ring of the cross block 15 in a ring array. A magnetic block 17 is embedded on the rear side of the positioning rod 16. An avoidance groove is opened on the front side of the connecting disk 11, and a pull rod 12 is fixed in the avoidance groove. The connecting disk 11 is inserted into the groove of the nut 1, and the positioning rod 16 is inserted into the positioning hole of the connecting disk 11. The magnetic block 17 and the iron block 18 are magnetically attracted to each other. The cross block 15 is inserted into the cross groove of the screw 13. When the explosion-proof valve is in contact with the battery pack, After the studs are docked, tighten the nut 1 onto the studs of the battery pack to fix the explosion-proof valve on the battery pack, thereby connecting the explosion-proof valve to the pressure relief port of the battery pack. At this time, the connecting plate 11 can be easily pulled forward and separated from the nut 1 through the pull rod 12. Then use a cross screwdriver to insert it into the cross groove of the screw 13 and rotate it, so that the anti-slip pad 14 is driven by the screw 13 to move backward and fit closely with the studs on the battery pack, thereby increasing the friction between the nut 1 and the studs on the battery pack, thereby improving the installation stability of the nut 1, and effectively ensuring the connection between the explosion-proof valve and the battery.

The mutual magnetic attraction between the magnetic block 17 and the iron block 18 can stabilize the positioning rod 16 in the positioning hole of the nut 1, and then the connecting plate 11 prevents the screw 13 from rotating through the cross block 15, thereby improving the contact stability between the anti-slip pad 14 and the stud on the battery pack, thereby improving the reliability of the device. The front side of the connecting plate 11 is flush with the front side of the nut 1.

[0020] Working principle: After the explosion-proof valve is docked with the stud on the battery pack, tighten the nut 1 on the stud of the battery pack to fix the explosion-proof valve on the battery pack, thereby connecting the explosion-proof valve to the pressure relief port of the battery pack. At this time, the connecting plate 11 can be easily pulled forward and separated from the nut 1 through the pull rod 12, and then a cross screwdriver is inserted into the cross groove of the screw 13 and rotated, thereby driving the anti-slip pad 14 to move backward through the screw 13 to fit tightly with the stud on the battery pack, thereby increasing the friction between the nut 1 and the stud on the battery pack, thereby improving the safety of the nut 1. The stability of the installation is improved, thereby effectively ensuring the connection strength and sealing between the explosion-proof valve and the battery pack. The connecting plate 11 is inserted into the groove of the nut 1, and the cross block 15 is inserted into the cross groove of the screw 13. At the same time, the positioning rod 16 is inserted into the positioning hole of the nut 1. The mutual magnetic attraction between the magnetic block 17 and the iron block 18 can stabilize the positioning rod 16 in the positioning hole of the nut 1, and then the connecting plate 11 prevents the screw 13 from rotating through the cross block 15, thereby improving the contact stability between the anti-slip pad 14 and the stud on the battery pack, thereby improving the reliability of the device.
