Abstract
The utility model discloses a thick and big chromatographic column bracket device. The thick and big chromatographic column bracket device comprises bottom leg leveling bolts (1), three stainless steel pipe supporting rods (phi 25 mm) (2), supporting plates (3), fixing plates (4 and 5), fixing screws (6), fastening bolts (61), fixing nuts (62), buffer gaskets (63) and nut gaskets (64), wherein round holes with certain hole diameters are formed in the fixing plates, so that chromatographic columns can conveniently penetrate through the fixing plates until the chromatographic columns fall on the supporting plates (3); the fastening bolts on the fixing plates (4 and 5) are used for fixing the chromatographic column; the buffer gaskets are fixed at the upper ends of the fastening bolts to achieve the buffer effect; the four to five supporting plates with different hole diameters are configured to support the chromatographic columns with different thicknesses; and the bottom leg leveling bolts (1) are favorable for leveling the chromatographic column bracket. The chromatographic column bracket is simple in structure, good in stability and convenient to use, and is suitable for the chromatographic columns with different specifications, so that the commonality is good. The phenomenons of high possibility of titling and loosing, poor stability and the like of the chromatographic columns fixed by using an iron support are avoided.
Description
Technical field:
The utility model belongs to a kind of thick chromatographic column holder device, belongs to the chemical experimental instrument technical field.
Background technology:
At present, the fixing of laboratory chromatographic column normally is fixed with two agrafes of cover on the iron stand, and there is more drawback in this method, and the fixedly difficulty for long or thicker chromatographic column can be larger especially.In general fixedly be not easy to make chromatographic column vertical with iron stand, time-consuming for the student, effort, very inconvenient; Easily become flexible with the tight of iron clamp sub-folder, the tension of folder can make the pillar unbalance stress again, above-mentioned situation more easily occurs for thicker pillar especially.Thereby these phenomenons can affect the separating effect that the filling of filler affects component.
Summary of the invention:
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and steadiness is good, and versatility is good, saves time, laborsaving, easy to use chromatographic column holder device.
The technical solution of the utility model is: a kind of chromatographic column support, by three stainless steel tubes (Ф 25mm) support bar, two fixed heads and a gripper shoe, on the fixed head by fastening bolt, hold-down nut, fixed screw, fixedly buffering spacer and footing leveling bolt form.Gripper shoe can be that a plurality of triangle plank quantity with different pore size are 4-5.It is characterized in that this device comprises three stainless steel tubes (Ф 25mm) support bars (2), the lower end of support bar (2) is equipped with footing leveling bolt (1) and is convenient to bracing frame adjustment level, three support bars are made bracing frame, characterized by further comprising and support fixed head (4,5) and a gripper shoe (3).Chromatographic column can pass through fixed head (4,5) arrive gripper shoe (3), the chromatographic column upper end is by fixed head (4,5) fastening bolt on (61), be fixed on fixed head (4,5) on the edge, the angle that fastening bolt becomes with circle center line connecting is 120 ℃, is used for fixing chromatographic column.A plurality of triangle plank quantity with different pore size are 4-5, can be placed on the chromatographic column of gripper shoe (3) upper support different thicknesses, are applicable to the rest of the chromatographic column lower end part of different thicknesses.
The utility model has the advantages that: on the fastening bolt buffering spacer is housed in this experimental provision, is convenient to the locking of chromatographic column and avoids pillar is damaged.Be provided with triangle plank gripper shoe and the fastening bolt of different pore size in this equipment, be adapted to the chromatographic column of different thicknesses, versatility is good, and equipment is simple, and is time saving and energy saving, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is the partial view of nut of the present utility model.
Number in the figure
1, footing leveling bolt 2, support bar 3, gripper shoe 4,5, fixed head 6, fixed screw 61, fastening bolt 62, hold-down nut 63, buffering spacer 64, nut shim
The specific embodiment:
See also Fig. 1-3, a kind of thick chromatographic column holder device is by support bar, gripper shoe, leveling bolt, 2 fixed heads, fastening bolt, hold-down nuts, fixedly buffering spacer, nut shim form.Fixed head (4,5) is provided with fixing fitting (comprising fastening bolt, hold-down nut, buffering spacer, nut shim), is conducive to chromatographic column vertically fixing, good stability.The fixed head lower end is provided with gripper shoe 3, and gripper shoe 3 comprises the gripper shoe of different pore size, is suitable for the rest to the chromatographic column of different thicknesses.
Using method
At first fetch the chromatographic column support, adjusting bottom leveling bolt (1) makes it be in level, chromatographic column is deeply passed through the circular hole of fixed head (4) downwards from the circular hole of fixed head (5), arrive the position of gripper shoe (3) (gripper shoe that matches with the pillar lower end), then by the fastening bolt (61) on fixed head (4) and (5) is adjusted, locking makes pillar be in plumbness to make its buffering spacer (63) contact gradually with pillar.Then carry out the interpolation of filler, the operations such as upper sample.
Claims (2)
1. chromatographic column holder device, it is characterized in that: this device comprises three stainless steel tubes (Ф 25mm) support bars (2), the lower end of support bar (2) is equipped with footing leveling bolt (1) and is convenient to bracing frame adjustment level, three support bars are made bracing frame, the diverse location of bracing frame is provided with two fixed heads (4,5) and a gripper shoe (3), fastening bolt (61) is fixed on (4,5).
