Abstract

The invention discloses a multifunctional solid-phase low-temperature electrochemical nuclear magnetic resonance combination system experiment support frame. The frame comprises a main frame, a low-temperature vacuum supporting and shock absorbing frame module, a low-temperature tank positioning and protecting frame module, a displaying frame module and a low-temperature chamber lifting module, wherein the main frame comprises longitudinal stand columns, transverse support rods, layer rods and a grounded wire; the longitudinal stand columns are used for dividing the main frame into a left magnet area and a right low-temperature area; the layer rods are used for dividing the main frame into an upper layer and a lower layer; the low-temperature vacuum supporting and shock absorbing frame module comprises positioning rods and shock elimination sheets; the low-temperature tank positioning and protecting frame module comprises positioning transverse rods, positioning vertical rods and a longitudinal stand column of the main frame; the displaying frame module is located on the lower layer of the right side wall of the main frame; the low-temperature chamber lifting module comprises positioning vertical rods, positioning transverse rods, a clamping hoop lifting disc set, a pulley block and a hand cranking device. Through the adoption of a non-magnetic splicing material, all the function modules are spliced on the main frame; the function expandability of the frame is improved; the vibration interference of a vacuum pump is reduced; the speeds in processes of assembling and disassembling the low-temperature chamber can be effectively controlled.
