Detailed Description

The invention will be further elucidated with reference to the drawing.

As shown in fig. 1 and 2, a volumetric flask tray for placing volumetric flasks comprises a chassis 1 and two vertical rods 2 arranged on two side edges of the chassis 1, wherein a cross rod 3 is connected between the two vertical rods 2, so that volumetric flasks can be placed on two sides of the cross rod 3, a first chute 21 is arranged on each vertical rod 2, the end part of the cross rod 3 slides up and down in the first chute 21, and two ends of the cross rod 3 are connected with two butterfly nuts 5 through threads, so that the height of the cross rod 3 can be adjusted through sliding up and down in the first chute 21, and the butterfly nuts 5 are screwed after reaching a preset position, so that the cross rod 3 is fixed with the vertical rods 2 and further fixed on the adjusted height;

be connected with a plurality of bottleneck fixing device 4 on horizontal pole 3 (bottleneck fixing device's quantity sets up according to the quantity of the volumetric flask that is fixed), bottleneck fixing device 4 includes connecting rod 41 and bottle neck ring 42, bottle neck ring 42 is through pivot and connecting rod 41 swing joint (bottle neck ring 42 also can be connected with connecting rod 41 through current other modes, for example universal ball is connected or articulated), after the volumetric flask was placed on the tray predetermined position, downwards rotate bottle neck ring 42 and make its bottleneck of entangling the volumetric flask, the height of whole horizontal pole 3 is adjusted to rethread butterfly nut 5, make bottle neck ring 42 cover the suitable position at the bottleneck of volumetric flask, can adapt to the volumetric flask of different specifications and bottleneck length, thereby make the volumetric flask stabilize on the tray, can not knocked over easily.

As shown in fig. 2 and 3, in order to adapt to different placement positions of the volumetric flask, the position of the bottleneck fixing device 4 is set to move left and right, the second chute 31 is arranged on the cross rod 3, one end of the connecting rod 41 of the bottleneck fixing device 4 is movably connected with the second chute 31, so as to drive the bottle neck ring 42 to move left and right, the movable connection mode can be that the connecting rod 41 is directly sleeved on the cross rod 3, so as to slide left and right in the second chute 31, and also can be the same as the connecting mode that the cross rod 3 and the vertical rod 2 pass through the butterfly nut, the butterfly nut is arranged on the connecting rod 41, so that the connecting rod 41 is connected with the cross rod 3 to be more fastened after reaching a preset position.
