The technological scheme that the utility model solves the problems of the technologies described above is as follows: a kind of liquid nitrogen match equipment of getting, comprise successively from the bottom to top chassis, cradle portion, and placing part; Below, described chassis is provided with roller; Described cradle portion comprises strut and pressing lever, and described strut is hollow structure, open-topped, and the sidewall of described strut is also provided with long strip opening, and the bottom of described strut is connected with described chassis, and the inside of described strut is provided with spring; Described pressing lever bottom is inserted in described strut inside via the opening of described supporting bar top, and described pressing lever is provided with convex button near the sidewall of bottom, and described convex button protrudes from described strut via aforementioned long strip opening; Described placing part comprises glove bar, horizontal stripe and tray, and described glove bar is flexibly connected with the top of described pressing lever; Described glove bar is fixedly connected with described tray by horizontal stripe.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the height of described strut inner spring is higher than the bottom of described long strip opening, lower than the top of described strut.
Further, the quantity of described horizontal stripe is two, and one end of described two horizontal stripes is connected with described glove bar respectively, and the other end of described two horizontal stripes is connected with described tray after connecting; Described two horizontal stripes and described glove bar besieged city triangle, the plane at described triangle place is vertical with horizontal plane.
Adopt the beneficial effect of above-mentioned further scheme to be, utilize the stability of triangular structure, can on tray, place the liquid nitrogen container of getting of larger volume, even and the liquid nitrogen of taking more weight can not damage device by pressure, extension fixture service time yet.
Further, described tray comprises bottom plane and around the fence of described bottom plane.
Adopt the beneficial effect of above-mentioned further scheme to be, the design of fence can make the placement of liquid nitrogen collecting container more firm.
Using method of getting liquid nitrogen match equipment of the present utility model is, installs after liquid nitrogen pump on liquid nitrogen container, liquid nitrogen container is placed on the chassis of apparatus of the present invention, and the container of collecting liquid nitrogen is placed on the tray of placing part; Because glove bar is flexibly connected with described pressing lever, therefore rotatable glove bar makes the liquid nitrogen collecting container on tray close with the device mouth that goes out liquid nitrogen, last press device top, the device mouth that goes out liquid nitrogen is inserted to vessel port, after loosing one's grip under the effect of spring liquid nitrogen collecting container with go out the device mouth close contact of liquid nitrogen, prevent that liquid nitrogen from leaking outside.After collection finishes, liquid nitrogen collecting container is taken out on press device top again.While not using for a long time, also placing part can be taken off, reduce the present invention and get taking up room of liquid nitrogen match equipment.
Of the present utility model to get liquid nitrogen match equipment easy to use, gets in liquid nitrogen process and do not need staff hand-held, saved manpower, also avoided the danger that may occur in working procedure.
