FIXING MECHANISM

摘要

A fixing mechanism disclosed in the present invention includes a body, a contact portion and an airtight sealing component. The body has a hollow structure and a first end and a second end. The first end is opposite to the second end. The first end passes through an open hole formed on a first object to insert into a positioning portion disposed on a second object, and an outer surface of the body is engaged with an inner surface of the positioning portion in a linear contacting manner. The contact portion is disposed on the second end. The contact portion contacts against a side of the first object opposite to the second object when the body passes through the first object and the second object. The airtight sealing component is disposed on the second end to seal the hollow structure, to prevent external gas from flowing into the hollow structure.

主权项

1. A fixing mechanism for fixing a first object on a second object, an open hole being formed on the first object, a positioning portion being disposed on the second object, the fixing mechanism comprising:
a body with a hollow structure, the body comprising a first end and a second end opposite to each other, the first end passing through the open hole to insert into the positioning portion, and an outer surface of the body being engaged with an inner surface of the positioning portion in a linear contacting manner; a contact portion disposed on the second end, the contact portion contacting against a side of the first object opposite to the second object when the body passes through the first object and the second object; and an airtight sealing component disposed on the second end to seal the hollow structure, so as to prevent external gas from flowing into the hollow structure.
