Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are implemented on the premise of the technical solution of the present invention, and the detailed embodiments and the specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, the multifunctional low-temperature balancing device of the present invention comprises a horizontal base 1; a support part is fixed on the horizontal base 1, and the support part is a support rod 2 vertically fixed at the center of the upper surface of the horizontal base 1; an equal-arm lever 3 is hinged on the support rod 2, namely the center of the equal-arm lever 3 is hinged on the support rod 2 through a rotating shaft.
An indicating part for displaying whether the equiarm lever 3 is balanced is arranged on the equiarm lever 3, the indicating part is a pointer 4 which is vertically and upwards fixed at the center of the equiarm lever 3, the pointer 4 can rotate along with the equiarm lever 3, when the pointer 4 deviates to the right, the right end of the equiarm lever 3 is heavier, and when the pointer 4 deviates to the left, the left end of the equiarm lever 3 is heavier.
In addition, the equi-armed lever 3 is also provided with a sample bearing part for bearing a sample to be leveled and providing a low-temperature environment for the sample to be leveled, and the sample bearing parts are two groups with the same structure and are symmetrically arranged at two ends of the equi-armed lever 3. Specific two sets of sample bearing parts are all including being fixed in the horizontal tray 5 on the equal armed lever 3 to and set up in 5 upper surface centers department of horizontal tray and be used for splendid attire refrigeration medium and wait to balance the cold-storage box 6 of sample, and the refrigeration medium can adopt isopropanol or ice water mixture, for the refrigeration medium that makes hold in cold-storage box 6 can continuously provide low temperature for waiting to balance the sample, still the cladding has thermal-insulated heat preservation skin 7 on the outer wall of cold-storage box 6.
In order to clearly display the temperature of the inner cavity of the cold storage box 6, the cold storage box 6 is made of a material (such as metal) with good thermal conductivity, and a thermometer 8 tightly attached to the side wall of the cold storage box 6 is longitudinally embedded on the side wall of the heat insulation and preservation outer layer 7, so that the refrigeration medium contained in the cold storage box 6 can transmit the temperature to the thermometer 8 through thermal conduction, and the temperature of the inner cavity of the cold storage box 6 is displayed by the thermometer 8. In addition, because it comes the splendid attire to wait to match the flat sample to adopt centrifuging tube or centrifuge cup, and centrifuging tube or centrifuge cup have multiple specification (if the centrifuging tube commonly used has 15ml and 50ml, the centrifuge cup commonly used has 400 ml), consequently in order to can adapt the centrifuging tube or centrifuge cup of different specifications, it has three opening annular slot 9 up to be arranged along the center form of dispersing on the inner chamber bottom surface of cold-storage box 6, equal vertical cartridge has annular baffle 10 in each annular slot 9, annular baffle 10 is the same with cold-storage box 6, adopt the better material of thermal conductivity to make, the equal adaptation of the internal diameter of each annular baffle 10 corresponds the centrifuging tube or centrifuge cup of a specification.
Further, in order to adjust the arm lever 3 to be horizontal before the sample to be leveled is not loaded, a leveling nut 11 is provided at one end of the arm lever 3. In order to make the horizontal base 1 stably placed on any rugged table, leveling support legs 12 are further arranged at four corners of the bottom surface of the horizontal base 1. In order to observe the weight difference at two ends of the equal-arm lever 3 in real time in the balancing process, a graduated scale 13 matched with the pointer is arranged on the support rod 2 above the equal-arm lever 3, a weight difference value mark 14 is marked on the graduated scale 13, and a reference position '0' of the weight difference value mark 14 is positioned at the center of the graduated scale 13 and is opposite to the pointer 4 when the equal-arm lever 3 is in the horizontal state, so that the adding and balancing of a sample to be leveled can be completed better and faster. In addition, in order to ensure the safety of the sample to be leveled and prevent the sample to be leveled from being scattered due to the excessive inclination of the equal-armed lever 3, the equal-armed lever 3 which is positioned right below the two horizontal trays 5 is provided with a vertically downward anti-falling supporting leg 15, the lower ends of the two anti-falling supporting legs 15 are a certain distance away from the upper surface of the horizontal base 1, the lower ends of the two anti-falling supporting legs 15 are positioned at the inner side of the horizontal base 1, when one end of the equal-armed lever 3 is inclined downwards to a certain angle, the lower end of the anti-falling supporting leg 15 can be jacked on the horizontal base 1, and therefore the excessive inclination of the equal-armed lever 3 is.
When the cold storage box is used, firstly, a proper annular partition plate 10 is selected and inserted into an annular slot 9 on the bottom surface of the inner cavity of the cold storage box 6, then a refrigerating medium is filled into a cavity formed between the annular partition plate 10 and the inner wall of the cold storage box 6, and leveling is carried out through a leveling nut 11; after leveling, a to-be-processed sample contained in a centrifuge tube or a centrifuge cup is directly placed into a cavity on the inner side of the annular partition plate 10, whether the equal-arm lever 3 is leveled or not is judged according to the direction of the pointer 4, and if the equal-arm lever is not balanced, the to-be-processed sample can be increased or decreased according to specific conditions until the leveling is completed.
