Vacuum system component mechanism
View Patent ↗A door lock structure is disclosed. The door lock structure is used to mount a fire door and includes a base, a pressing component, a pressing shell and a locking component. The base is disposed on the fire door and has an accommodation groove, and a groove bottom of the accommodation groove has a first locking hole. The pressing component includes a pressing base, a roller column, a fixing plate, an elastic part and a locking part.
1 . A vacuum system component mechanism, comprising:
a pump support base;
an upper support part, wherein one end of the upper support part is fixed to a bottom surface of the pump support base; and
a joint bearing connected to an other end of the upper support part in an angle-adjustable manner, wherein the joint bearing comprises:
a plate;
a bearing base horizontally disposed on one surface of the plate, wherein a through hole is formed through a center of the bearing base; and
a universal ball bearing rotatably disposed in the through hole.
2 . The vacuum system component mechanism as claimed in claim 1 , wherein the bearing base is screwed on one surface of the plate.
3 . The vacuum system component mechanism as claimed in claim 2 , further comprising:
a pump support adjustment base disposed parallel to the plate, wherein the pump support adjustment base and the plate are separated by a distance.
4 . The vacuum system component mechanism as claimed in claim 3 , further comprising:
a plurality of first screw components, each of the first screw component screws the plate and the pump support adjustment base, respectively.
5 . The vacuum system component mechanism as claimed in claim 4 , wherein the distance is increased or decreased through adjusting the plurality of first screw components.
6 . The vacuum system component mechanism as claimed in claim 5 , further comprising:
a connecting device, and one end of the connecting device is adjacently connected to the upper support part and an other end of which is fixed to the joint bearing.
7 . The vacuum system component mechanism as claimed in claim 6 , wherein the connecting device comprises:
a connecting plate, and one surface of the connecting plate is orthogonally connected to the upper support part;
a guiding rod disposed on and orthogonally connected to the other surface of the connecting plate,
wherein the guiding rod is connected with a shaft hole of the universal ball bearing at the center of the bearing base.
