Preferably, the top outer wall welding of spacing post has the spring, and the top outer wall of spring and the top inner wall welding of mounting groove set up.

The utility model has the advantages that:

1. the utility model provides a pair of sealed effectual welding double-screw bolt, be provided with the support chassis through the bottom at the threaded rod, and set up the arc recess that annular array distributes at the circumference outer wall that supports the chassis, set up the welding hole that annular array distributes at the circumference outer wall that supports the chassis top, the area that can effectual improvement welding department of setting up of arc recess and welding hole, and then improve welding area, and then welded stability has been guaranteed, this kind of mode that all carries out the welding at edge and middle part simultaneously can effectual improvement welded seal effect, further guarantee the stability of device.

2. The utility model provides a pair of sealed effectual welding stud is provided with the lug that annular array distributes through the circumference outer wall that supports the chassis bottom, can set up the recess with lug equidimension on the installing component, makes the lug card in the recess, further assurance fixed stable and sealed effect.

3. The utility model provides a pair of sealed effectual welding double-screw bolt through being provided with spring, spacing post and stopper, can set up spacing hole on the installation component to make spacing post insert in spacing hole, the setting of stopper can effectually avoid the device to produce the rotation, and the setting of spring can effectually guarantee that spacing post pushes up the deepest of going into spacing hole, guarantees area of contact, improves the stability of installation.
