Problems solved by technology
Most of the existing chromatographic column hangers only have suspension arms or only fixed arms. For example, the hanger of a gas chromatograph produced by a certain company is composed of four fixed arms, but without suspension arms, the chromatographic column cannot be temporarily fixed, which is very unfavorable for operation. For another example, the hanger of a gas chromatograph produced by a certain company has two suspension arms without a fixed arm. Facilitates column movement during operation
These are not conducive to the operation or the chromatographic column is not firmly fixed, which affects the convenience of the daily use of the gas chromatograph

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0010] Such as figure 1 As shown, the chromatographic column hanger in the gas chromatograph column box of the present invention includes a suspension arm 8 and two fixed arms 5 .
[0011] Suspension arm 8 is made of spring 1, movable inner rod 2, overcoat 3, cap 4 four parts of interior. The inner rod 2 of the suspension arm is connected with the hat 4 of the suspension arm, and when the hat 4 is pulled, the inner rod can move forward and backward. Thus, the column rack can be clamped between the cap 4 and the jacket 3 of the suspension arm. After completing the disassembly and assembly of the chromatographic column, the final fixation of the chromatographic column is carried out with the two fixed arms.
[0012] One suspension arm 8 can temporarily fix the chromatographic column to facilitate operation; two fixed arms 5 can firmly fix the chromatog...

Abstract
The invention relates to a chromatographic column hanging rack in a gas chromatograph column box, wherein a suspension arm and two fixed arms are distributed in an isosceles triangle; the suspension arm is arranged at the vertex angle of the triangle and is embedded on a baffle of a fan; the two fixed arms are respectively arranged at the two waist angles at the bottom of the triangle; the suspension arm consists of a spring, a movable inner rod, an outer sleeve and a cap; the movable inner rod is arranged in the fixed outer sleeve; one end of the movable inner rod is connected with the cap used for blocking a chromatographic column frame by the spring; each fixed arm is formed by a thin and long metal strip; one side of each fixed arm connected with a chromatographic column is bended to form a hook, and the other side of the fixed arm is fixed by a screw. The chromatographic column hanging rack has the characteristics that the structure is simple, the chromatographic column can be assembled and disassembled by a chromatograph operator, the chromatographic column is firmly fixed, etc.
Description
technical field [0001] The invention relates to a gas chromatograph column box, in particular to a chromatographic column hanger. Background technique [0002] The chromatographic column rack is an important component in the gas chromatograph column box, which is responsible for the mounting and fixing of the chromatographic column. Most of the existing chromatographic column hangers only have suspension arms or only fixed arms. For example, the hanger of a gas chromatograph produced by a certain company is composed of four fixed arms, but without suspension arms, the chromatographic column cannot be temporarily fixed, which is very unfavorable for operation. For another example, the hanger of a gas chromatograph produced by a certain company has two suspension arms without a fixed arm. Facilitate the movement of the chromatographic column during operation. These are all unfavorable for operation or are not firmly fixed to chromatographic column, have influenced the conven...
