End, supporting box outer end face top are connected by hinge with hollow cage plate, and the hollow sleeve intralamellar part is provided with flexible
Plate, the expansion plate lower end are fixed with connection stick, and the connection stick lower end is connected by bolt with movable pulley, in described
Empty set plate rear and front end is each equipped with fixed column, and threaded rod is equipped in the fixed column, and the threaded rod lower end setting is being propped up
Box house is supportted, the support plate is mounted on inside household freezer.
6. a kind of experiment freezing equipment according to claim 5, it is characterised in that：The support plate lower end is machined with cunning
Dynamic slot, and sliding groove is internally provided with sliding shoe, and sliding shoe is connected by bolt with sliding bar upper end, the supporting box
Lower end is inlaid with inflator, and inflator upper end is connected by tracheae with cavity, the sliding bar annular side and hollow tube
Road contact position is provided with ring type seal, and the hollow sleeve upper end is fixed with top plate, and the household freezer lower end offers card
Household freezer is placed on supporting box upper end by slot, and card slot is internally provided with top plate, in actual use, user of service, and to
Lower mobile household freezer, is in contact so as to cause card slot with top plate, and then user of service is pulled along support plate, and support plate is to Forward
It moves to be stretched out from household freezer front end, then user of service will test object and place on the supporting plate, and then user of service pushes away again
Dynamic support plate is moved backward along sliding shoe, when support plate moves backward to suitable position, is stopped pushing support plate, then be opened
Dynamic inflator, inflator work drives air flowing, and then outside air is caused to enter cavity inside, as air continues into
Cavity inside leaves cavity so as to cause air, and enters inside hollow sleeve, so drive sliding bar along hollow sleeve to
Upper movement, sliding bar, which moves up, drives support plate to move up, and support plate moves up drive experiment object and moves up, and is propping up
When fagging is moved upwards up to suitable position, stops inflator, realize the function of support, and can be lifted.
7. a kind of experiment freezing equipment according to claim 5, it is characterised in that：The threaded rod upper end is fixed with hand
Handle, there are two slot corresponding with handle, hollow sleeve intralamellar part tops for supporting box upper surface rear portion symmetrical machining
End is fixed with electric pushrod, and electric pushrod lower end is provided with expansion plate, and electric pushrod is connected by conducting wire with external power supply
It connects, the threaded rod is connected by screw thread with fixed column, and the supporting box lower end is machined with circular hole, and setting inside circular hole
There is threaded rod lower end, in actual use, user of service starts electric pushrod, and electric pushrod work drives expansion plate to moving down
Dynamic, expansion plate moves down drive connection stick and moves down, and connection stick, which moves down, drives movable pulley to move down, in turn
It drives movable pulley to be touched with ground, and then supporting box is lifted, when needing to protect household freezer, user
Member holds handle, and is rotated, and handle rotation drives threaded rod rotation, because threaded rod is connected by screw thread with fixed column
It connects, so threaded rod is rotated and moved up, and then causes threaded rod lower end to be separated with circular hole, during then user of service holds
Empty set plate is simultaneously rotated around hinge, the rotation of hollow cage plate drive simultaneously expansion plate, connect stick, movable pulley, fixed column with
And threaded rod is rotated, when hollow cage plate turns to suitable position, stop operating hollow cage plate, then rotates screw thread again
Bar, threaded rod rotate to move down, and threaded rod moves down band fixed handle and moves down, and then handle is caused to enter slot
Inside, and then limited to hollow sleeve plate, is then again started up electric pushrod, and electric pushrod work drives expansion plate to moving up
Dynamic, expansion plate moves up drive connection stick and moves up, and then movable pulley is driven to move up, and is moved up in expansion plate
When to suitable position, stops electric pushrod, realize mobile function, and can be protected.
