Specific embodiment
For the purpose and effect for the technical characteristics of the utility model being described in detail He being realized, do below in conjunction with attached drawing into one
The description of step:
As shown in Figure 1, cold plate floating installation on a kind of contact blood plasma quick freezer, including rack 1, lower cold plate 15 are fixed on
1 top of rack；A guide sleeve 13 is respectively mounted in the quadrangle of rack 1；The quadrangle of upper cold plate 14 is respectively mounted with that one is led
To bar 12, guide rod 12 is inserted in guide sleeve 13, and can be slided up and down, the lower end difference of 2 guide rods 13 of the left and right sides
It is connected and fixed with the floating connection block 6 of the left and right sides, a spring cushion block is respectively set above the floating connection plate 6 of the left and right sides
7, the outside of each spring lock block 7 is cased with a compressed spring 8, and each 8 lower end of compressed spring is attached to each floating connection
On plate 6, one piece of spring lock block 10 is respectively placed in each 8 upper end of compressed spring；It respectively places the lower section of the floating connection block 6 of the left and right sides
One pusher bar support 5；Pusher bar support 5, floating connection plate 6, spring cushion block 7, compressed spring 8 and the spring lock block 9 of the left and right sides
It is respectively sequentially passed through by a screw rod 9, and passes through a nut 11 in the upper end of every screw rod 9 and connect, forming one has bullet
The relocation mechanism of property；The pusher bar support 5 of the left and right sides is respectively connect by a shaft 4 with one end of an electric pushrod 3, and left
The other end of the electric pushrod 3 of right two sides respectively passes through a shaft 4 and connect with a motor supporting base 2, the left and right sides it is electronic
The both ends of push rod 3 can be rotated around respective shaft 4, so that entire floating installation be enable to accommodate manufacture and assembly bring
Various errors, it is ensured that upper cold plate 14 moves up and down more efficient；Motor supporting base 2 is fixed in rack 1.
As shown in Fig. 2, guide support plate 16 is fixed in rack 1, guide sleeve mounting base 17 is fixed on guide support plate 16
On, in the insertion guiding installation set 17 of guide sleeve 13, both ends are blocked with big circlip 18；Lock screw is used respectively in the both ends of guide rod 13
19 are connected and fixed with upper cold plate 14 and floating connection plate 6；The shaft 4 at the both ends of electric pushrod 3 is blocked with small circlip 20 respectively, is prevented
The axial movement of rotation stop axis 4；When upper cold plate 14 will move downward, the electric pushrod 3 of two sides moves at the same time contracting, upper 14 edge of cold plate
Guide sleeve 13 move downward, the stopping when electric pushrod 3 returns to designated position, pusher bar support 5 and floating connection plate 6 divide at this time
From compressed spring 8 is compressed, and upper cold plate 14 keeps coming into full contact with blood bag under the drop-down effect of left and right sides compressed spring 8；
When needing to rise upper cold plate 14, the simultaneously operation of electric pushrod 3 of the left and right sides, which is stretched out, jacks up respective pusher bar support 5, left and right two
Power is transmitted to respective floating connection plate 6 after sticking by side pusher bar support 5 and respective floating connection plate 6, in promotion cold plate 14 to
Upper movement, upper cold plate 14 leave blood bag, any active force will not be generated to blood bag, securely and reliably, additionally, due to the left and right sides
3 both ends of electric pushrod can be rotated around respective axis, there is certain freedom degree, and cold plate 14 is swimmingly transported up and down
It is dynamic.
As shown in figure 3, the above cold plate 14 is that object is analyzed, when squeezing blood bag, the power being subject to has: self gravity
G, the pulling force 2F of two compressed springs 81, the support force F of blood bag2, frictional force F between guide rod 12 and guide sleeve 13f, upper cold
Reaction force F of the heat-preservation cotton on 14 periphery of plate by lower cold plate 153, due to FfAnd F3It is smaller, it ignores, according to the balance of power
Condition can be calculated: F2=2F1+G；According to the relationship of power and reaction force, the pressure size that blood bag is subject to is equal to F2；And it is upper cold
The self gravity G of plate 14 is definite value, according to Hooke's law, the active force of every compressed spring 8: F1=kx, k are constant, and x is bullet
The deformation quantity of spring selectes compressed spring 8, then the power F that blood bag is subject to according to the actual situation2Size be known, and due to pressure
The flexible deformation of contracting spring 8 can float with the difference of blood bag thickness and change, avoid blood bag by rigid extruding, it is ensured that upper cold
It is effective face contact between plate 14 and blood bag, improves refrigerating efficiency；The pressure size F that another aspect blood bag is subject to2It can be uniform
Ground is assigned in each blood bag, to guarantee that blood bag stress is safe and reliable and uniform, meets the purpose of this utility model and effect
Fruit.
