Embodiment
Below in conjunction with the accompanying drawings with embodiment, the utility model is further illustrated.
As shown in Figures 1 to 5, a kind of closely sealed device of exposure machine vacuum of the utility model, including upper framework 1 and underframe 2,
The end of the upper framework 1 and underframe 2 is provided with the upper connector 3 and lower connector 4 of activity pivot joint, in the underframe 2
End in the middle part of be additionally provided with a spherical joint 5, provided with the company being connected with the spherical joint 5 in the middle part of the end of the upper framework 1
Connect cover body 6, wherein it is in "L" shaped that the upper connector 3 is overall, the end of the upper connector 3 forms top-joining part 7, it is described on
The inside portion of connector 3 is provided with link slot 8, and the rear end of the lower connector 4 is provided with the turn hole for assembling rotating shaft, described
Upper connector 3 by provided with rotating shaft mating connection groove 8 be pivotally connected with the activity of lower connector 4, the front end of the lower connector 4
Transition face 9 is formed between portion and top ends, cylinder startup can be offset in an instant by coordinating by top-joining part 7 and lower connector 4
Impulse force, can be toward being raised with the jack-up top-joining part 7 of upper framework 1 so as to play a part of protecting rotating shaft, transition face 9 is set
Squarely face or arc surface can avoid top-joining part 7 from being collided with lower connector 4, and realization is preferably rotated, and spherical joint 5 and company
The rotation agility of upper framework 1 can be increased by connecing the cooperation of cover body 6, while playing middle part firm effect.
The middle-end of framework 1 and underframe 2 is connected with a driving member 10 on described, and the driving member 10 is connected with
Cylinder 11 is opened, it is described to open the side edge that cylinder 11 is arranged at the underframe 2, the side for opening cylinder 11 and underframe 2
Along being flexibly connected by rotating shaft, the junction of the output shaft and driving member 10 that open cylinder 11 is placed in the front end of driving member 10, such as
This opens the upper framework 1 of the jack-up of cylinder 11 and curved can then opened, and the upper framework 1 and underframe 2 are respectively provided with glass
12 and lower glass 13, the periphery of the lower glass 13 is provided with the air-tight rubber strip 14 of annular, and the inside of air-tight rubber strip 14 is hollow
Adhesive tape and fixed material sealed by fluid sealant etc. be fixed on underframe 2, be provided with air-filled pore 15 on the underframe 2
And aspirating hole 16, the air-tight rubber strip 14 is provided with the through hole that is connected with air-filled pore 15, and the aspirating hole 16 is arranged at gastight adhesive
