Description
Technical field
The present invention relates to one kind to rotate door switch unit, more particularly to a kind of double hinge shaft lifting rotation door switch units.
Background technology
Large epoxy ethane sterilizer is the pass for being used to finally sterilize to medical device product in medical instrument production
Button apparatus.Ethylene oxide sterilizer is under certain temperature, pressure and damp condition, with certain density ethylene oxide gas pair
It is sealed in the equipment that indoor medical instrument carries out low temperature suffocating sterilization that sterilizes.The sterile medium ring that ethylene oxide sterilizer uses
Oxidative ethane gas is a kind of very effective low temperature sterilization agent, is at home and abroad widely used.But ethylene oxide is one again
Hypertoxic, inflammable, the explosive chemical substance of kind, it is desirable to cannot be leaked in sterilization process.Therefore it is required that ethylene oxide sterilizer must
There are enough intensity, good leakproofness, easy for operation and good security.
Large-scale sterilizing device refers to sterilizer sterilizing chamber volume more than 1 cubic metre, and the sterilizer of largest domestic has reached at present
100 cubic metres.Sterilizing chamber is generally made of the feeding gate and discharge door at babinet and both ends.The door body at both ends be it is switchable, when
When needing sterilizing, feeding gate is opened, it would be desirable to which the medical instrument of sterilizing incases in vivo, is then shut off feeding gate and goes out
Bacterium.After the completion of sterilizing works, discharge door is opened, again closes discharge door after sterilized medical instrument is released, is next
A sterilization cycle is prepared.Therefore door body is the important component of ethylene oxide sterilizer.Sterilizer mainly will to door body
Seeking Truth：Have enough strength and stiffness, the positive pressure and negative pressure of repeated action in babinet can be born caused by pressure, do not produce
Crackle and obvious plastic deformation.It cannot all be leaked by positive pressure and negative pressure in babinet, door body switching manipulation is convenient, safe and reliable.
The switching device of door body to meeting that functional requirement of the sterilizer to door body has a great impact, door body switching device

During with opening the door on the contrary, at closing time door body first around 23 opposite direction of door body door-hinge rotate a minute angle 2 α after spacer pin with
The side wall contact of limit hole, the relative rotation of door body and contiguous block stop, and door body drives contiguous block to cause around door when being rotated further
Frame door-hinge 21 rotates.When the one side of door body away from door-hinge touches doorframe, if firmly larger at closing time, plus the used of door body
Property, the opposite side of possible door body are also adjacent to doorframe, and at this moment cylinder exhaust, door body can be smoothly fallen on gate stop down.If close
Firmly smaller during door, the inertia of door body is also smaller, and behind the side of door body and door frame contact, the opposite side of door body is (close to door-hinge one
Side) may be with the gap c of doorframe formation, it is impossible to it is adjacent to doorframe.But due to having determined that spacer pin and limit hole during design
2 δ of gap, it is ensured that gap c is less than original door body and the maximum clearance of doorframe, this can guarantee that when door body declines not by gate stop card
Firmly.The effect of double hinge shafts is to ensure that the opposite doorframe of door body energy moves in parallel, and the effect of spacer pin is to limit door body translational movement not
More than prespecified numerical value.
