The advantage that the utility model has and good effect are: because the utility model structure is simple, the materials such as useable glass are made, with low cost; By the unlatching of single fixture, closed, the installation of sample can be completed quickly and easily, pull down, processing ease, time saving and energy saving; Seal groove, O-ring seal set on cup end face suitable for reading, have good sealing effectiveness.During off-test, device need not be waited to cool, rapidly device can be inverted, stop the contact of transport materials and food analogies, ensure that the duration of contact of each sample is as far as possible consistent, thus ensure that accuracy and the repeatability of experiment.
Accompanying drawing explanation
Fig. 1 is the detecting migration quantity of chemical substance in food packaging material structural representation that the utility model embodiment provides.
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows: the utility model does not exist the innovation of software or method.
Refer to Fig. 1:
As shown in Figure 1: the cup 1 that useful glass is made, the end face suitable for reading of cup 1 is provided with seal groove 2, seal groove 2 is built-in with full bag fluorine plastic cement first O-ring seal 3, first O-ring seal 3 is placed with glass capsulation lid 4, stationary fixture 5 is had, to be fixed in cup 1 upper end and gland bonnet 4 in the outer surface cover of cup 1 upper end and gland bonnet 4.Described fixture 5 is provided with broken ring 6, inside the upper end of broken ring 6, have pickup groove 7, places the second O-ring seal 11, be provided with opening adjusting device at the opening part of broken ring 6 in pickup groove 7.Described opening adjusting device is provided with the spanner 8 being movably connected on broken ring 6 opening side, and spanner 8 is fixed with screw rod 9; The opposite side of broken ring 6 opening is fixed with the setting nut 10 matched with screw rod 9, and the termination of described screw rod 9 is placed between broken ring 6 and setting nut 10.
