The pre-assembled locking pin 30 is also blocked by the double crimp port 704 abutted by the inclined surface 106 and cannot be removed.

The hinge sleeve 90 preassembled on the chassis door panel 80 is sequentially clamped into the first gap 1013 of the hinge base 10, so that the through hole of the hinge sleeve 90 is aligned with the through hole 1015 of the hinge base 10, then the hinge pin 20 is inserted into the through hole 1015, the stop surface 204 of the first pin head 201 is abutted with the outer side surface 107, the pin head of the lock pin 30 falls into the arc groove 203 of the hinge pin 20, the above steps are repeated, the chassis door panel 80 is connected with the box body 70 into a whole through the hinge base assembly, the locking chassis door panel 80 is closed, and the inner surface 801 is provided with the closed adhesive tape 802, is matched with the double-folded edge opening 704 of the box body 70 in size and is in elastic contact in position, so that the integral IP grade of the finished chassis in the final assembly is finished.
