Description
Technical field
The present invention relates to a kind of pressure equalisers, especially a kind of pressure equaliser for low-temp. refrigerator.
Background technology
Low-temp. refrigerator, especially super low-temperature refrigerator（-86℃）, being picked and placeed in enabling can not be again in the short time after article is closed the door
It opens the door, generally requiring half an hour or more can just open the door again.Main cause is that the pressure inside and outside cabinet is not in equilibrium state, cabinet
Interior pressure is less than cabinet external pressure.
Invention content
The object of the present invention is to provide it is a kind of it is simple in structure, refrigerator internal and external pressure balance, easy to operate, body can be adjusted at any time
The product pressure equaliser for low-temp. refrigerator that is small, being not take up space, needs to fall into a long wait after overcoming low-temp. refrigerator to open the door
The drawbacks of could opening the door again.
The pressure equaliser for low-temp. refrigerator of the present invention, including shell, fixed in shell finite place piece with can
The knob of axial movement is equipped with spring between locating part and knob, is equipped with rear cover in an end of shell, the end face of knob is certainly
Another end of shell is exposed, and gasket is equipped between the end face periphery and the inner side end of shell of knob, in locating part, knob
It is covered with after and is respectively equipped with locating part hole, knob hole and back cover hole.
It is the connection that is screwed between the locating part and shell, the end face of locating part acts against the step of case inside
On；The slideway for facilitating knob to move axially is equipped between the knob periphery and the inside of shell；The rear cover and shell
Between for be threadedly coupled；Being fastened in the end point of shell has the buckle closure for preventing condensing under hot and humid environment.
The pressure equaliser for low-temp. refrigerator of the present invention, can be fixedly mounted on refrigerator door or cabinet by foam pattern
On body side surface, rear cover one end is located on the inside of cabinet, and knob end face is located on the outside of cabinet.After enabling, which picks and places article, closes the door again,
Knob can be pressed, spring is made to be pressurized, at this point, cabinet inner cavity is connected to on the outside of cabinet by back cover hole, locating part hole, knob hole,
Cabinet external pressure dynamic balance in cabinet is realized, cabinet is inside and outside in partition state after release button, without waiting for the long period after shutdown
Can open the door again, have it is simple in structure, refrigerator internal and external pressure balance can be adjusted at any time, is easy to operate, small, be not take up sky
Between the advantages of.
Description of the drawings
Fig. 1 is the structural schematic diagram of the specific embodiment of the invention；
Fig. 2 is that specific embodiment of the invention middle casing end fastens the structural schematic diagram for having buckle closure.
Specific implementation mode
As shown in Figure 1, 2：The pressure equaliser for low-temp. refrigerator of the present invention, including tubular shell 2, in shell 2
Interior fixed finite place piece 5 and the knob 1 being axially movable.
Spring 3 is equipped between locating part 5 and knob 1.It is fixed with rear cover 4, the end of knob 1 in an end of shell 2
Face is exposed from another end of shell 2, and gasket 6 is equipped between the end face periphery and the inner side end of shell 2 of knob 1.It is limiting
It is respectively equipped with locating part hole 9, knob hole 8 and back cover hole 10 on position part 5, knob 1 and rear cover 4.
It is the connection that is screwed between locating part 5 and shell 2, the end face of locating part 5 acts against the step of 2 inside of shell
On.
The slideway for facilitating knob 1 to move axially is equipped between 1 periphery of knob and the inside of shell 2.Rear cover 4 and shell 2 it
Between for be threadedly coupled.Being fastened in the end point of shell 2 has the buckle closure 7 for preventing from condensing under hot and humid environment, while to knob 1
Play protective effect.
The pressure equaliser for low-temp. refrigerator of the present invention, can be fixedly mounted on refrigerator door or cabinet by foam pattern
On body side surface, 4 one end of rear cover is located on the inside of cabinet, and 1 end face of knob is located on the outside of cabinet.It closes the door again when enabling picks and places article
Afterwards, knob 1 can be pressed, spring 3 is made to be pressurized, at this point, passing through back cover hole 10, locating part hole 9, knob on the outside of cabinet inner cavity and cabinet
Hole 8 is connected to, and realizes cabinet external pressure dynamic balance in cabinet, and cabinet is inside and outside in partition state after release button 1, after shutdown without waiting
Long period can open the door again, have it is simple in structure, refrigerator internal and external pressure balance can be adjusted at any time, is easy to operate, small,
The advantages of being not take up space.
