One mandril (or top plate), mandril (or top plate) jack up target plate, move up and down target plate from below, complete disengaging sample.But fly
The depth of the vacuum cavity of row time mass spectrum instrument disengaging sample is limited, and space is smaller, and the prior art uses more complicated connecting rod machine more
Structure realizes lifting target operation by the external force of horizontal direction in the cavity, and being completely independent for lifting target assembly is not implemented, and is moving
Interim card easily occurs during dynamic, or even causes vacuum leak.
Utility model content
The utility model provides a kind of lifting target assembly of Matrix-assisted laser desorption ionization instrument, solves
The easy interim card of existing lifting target assembly, the problem of leakproofness is insufficient.
A kind of lifting target assembly of Matrix-assisted laser desorption ionization instrument, including base, the base
Driver, conduction mechanism and vertically extending mandril are equipped with, the conduction mechanism is connected with mandril and driver respectively,
Under the driving of driver, the mandril vertically moves up and down；Fixed plate is further included, the fixed plate is equipped with sleeve, described
Fixed plate and sleeve are equipped with perforative via, and the mandril is formed through the via in fixed plate and sleeve and on the top of mandril
Tray, is further fixed on telescoping tube, the telescoping tube and tray are used to extend into mass spectrograph, and stretch between the tray and sleeve
Space in the space and mass spectrograph that the draw and sleeve are coated is independent.
The radius of the tray is more than the radius of mandril, and the lower face of the telescoping tube and tray is fixedly linked.
The top of the base is equipped with the groove that is recessed inwardly, and the lower end of the conduction mechanism and mandril is arranged at described
In groove, the driver is fixed on the lateral wall of base, and the output terminal of driver extend into institute from the lateral wall of base
State in groove.
The lateral wall of the base is further fixed on the transverse slat extended laterally, and the transverse slat, which is equipped with, to be used to install firm banking
Mounting hole.
The telescoping tube is bellows.
In the utility model, telescoping tube and tray will be extend into mass spectrograph, and sleeve and telescoping tube envelope mandril, and
The space of cladding is independent with mass spectrograph inner space, then in mandril moving process, telescoping tube is elongated or shortened with tray, but its
The space of cladding is still independent with mass spectrograph inner space, thus it has very strong leakproofness, ensure that during passing in and out sample
Security.Meanwhile the mandril of the utility model is to be extend into outside mass spectrograph in mass spectrograph, and there is dedicated driving dress
Put, realize being completely independent for lifting target assembly, be not in interim card in moving process so as to add stability.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the lifting target assembly of embodiment of the utility model；
Fig. 2 is that a kind of lifting target assembly of embodiment of the utility model is installed on the structure diagram on mass spectrograph.
