Detailed Description

With reference to fig. 1, fig. 4 to fig. 6 and fig. 7, the carrier structure of the liquid chromatograph includes a base 10 fixedly disposed, and a pull-out assembly movably fitted on the base, wherein a latch mechanism is disposed at an outer end of the pull-out assembly, and the latch mechanism includes a button 21 hinged to a top of the pull-out assembly, a stopper 22 disposed at a bottom of the pull-out assembly, and a connecting rod 23 connecting the button and the stopper; the outer end of the base is provided with a limit edge 11 which can be abutted against the limit block.

As shown in fig. 5, the limiting block 22 is disposed on the base block 220 and is triangular, and the base block is disposed at the bottom of the outer end of the pull assembly through the elastic metal sheet 221, so that when the pull assembly is pushed into the base to be reset, the limiting block can cross the limiting edge 11 and then abut against the inner side of the limiting edge. The button 21 is installed in the outer end of pull combination body through hinge pin 210, and the operator is pressing the outer end of button 21, and the inner perk of button, pulling connecting rod 23 rise, and connecting rod pulling base block 220 rises, and then the stopper rises, and the stopper breaks away from with spacing edge.

With reference to fig. 2, 3, 4 and 8, the drawing assembly includes a sliding table 30 and a drawer 20, the base 10 is provided with a first sliding groove 12, and the bottom of the sliding table is provided with a first sliding block 31 engaged with the first sliding groove; the two sides of the drawer are provided with second sliding blocks 24, the upper surface of the sliding table is provided with a drawer groove 32, the two sides of the drawer groove are provided with second sliding grooves 33, and the second sliding blocks are matched in the second sliding grooves. Through the first sliding chute and the first sliding block, the sliding table can be pulled and pulled along the base; through second spout and second slider, the slip table pull can be followed to the drawer. The combination of the sliding table and the drawer is beneficial to the miniaturization design of the liquid chromatograph carrying table, and further beneficial to the miniaturization of the liquid chromatograph.

The latching mechanism is specifically mounted at the outer end of the drawer 20.

Two sides of the upper surface of the sliding table 30 are provided with positioning edges 34, the inner end of the drawer 20 is provided with a positioning block 25, a second sliding groove 33 is internally provided with a limiting sheet 35, and a second sliding block 24 is provided with a limiting recess 26 which can be matched with the limiting sheet; when the limiting piece is matched with the limiting recess, the positioning block is positioned at the inner side of the positioning edge as shown in figure 2.
