Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Assembling: screw four positioning nuts 10 on the bottom of four connecting rods 12 upward by about 1cm, pass through four connecting holes 9 of the positioning bottom plate 4 downward, screw cover-shaped nuts 13, then screw the four positioning nuts 10 on the four connecting rods 12 upward, install the middle opening plate 2, then screw the four positioning nuts 10 on the four connecting rods 12 upward, fix the middle opening plate 2, then screw the four positioning nuts 10 on the four connecting rods 12 upward by about 1cm, put the catheter handle 1, screw the cover-shaped nuts 13, and finally adjust the positioning nuts 10 to make the plates flat.

[0032] Eight flushing capillary tubes 25 are bundled and passed through the double-head tower joint 24, the inside gap of the double-head tower joint 24 is filled with epoxy resin, after the epoxy resin solidifies, the flushing capillary tube 25 is left with a length suitable for the length of the Gerber butter meter A at one end, and the other end is cut to be flush with the other end of the double-head tower joint 24.

[0033] When testing, the assembled Gerber fat tester is fixed and washed, and the pipe handle 1 is upwardly and horizontally placed on the test table. The A mouth of the Gerber fat tester is upwardly inserted through the bottle body fixing hole 6 of the middle opening plate 2. The side opening movable plate 3 is lifted by hand. The thin neck of the Gerber fat tester A is inserted from the bottle neck side opening fixing hole 7 of the side opening movable plate 3. The heart bubble top end of the Gerber fat tester A is inserted into the heart bubble top fixing hole 8 of the positioning bottom plate 4. The side opening movable plate 3 is lowered. Under the action of the spring force, the heart bubble of the Gerber fat tester A is clamped by the side opening movable plate 3 and the positioning bottom plate 4. The required other Gerber fat testers A are sequentially inserted. The sample and the test solution are injected according to the operation regulation. The bottle plug is tightly plugged. The whole Gerber fat tester fixing and washing frame is reversed. The pipe handle 1 is downwardly placed. The water bath is tested. At this time, under the clamping of the Gerber fat tester fixing and washing frame, the Gerber fat tester is always stable whether it is placed vertically or horizontally.

[0034] It is well known that the peristaltic pump has the functions of setting forward rotation and reverse rotation. Water is introduced when the peristaltic pump is forward rotated, and water is discharged when the peristaltic pump is reverse rotated. The corrosive waste liquid or chromic acid washing liquid only runs in the pipe, and has corrosion resistance.

[0035] The flushing pump pipeline is connected. The eight flushing capillary tubes 25 are respectively inserted through the corresponding flushing pipe fixing holes 5 to fix the flushing capillary tubes 25, so that the flushing capillary tubes 25 are prevented from being separated from the Gerber fat tester during flushing. The other ends of the flushing capillary tubes 25 are bundled and inserted into the double-head tower joint 24 and sealed. The single-end of the double-head tower joint 24 is connected to the flushing pump water outlet pipe 23. The other end of the flushing pump water outlet pipe 23 is connected to the flushing pump water outlet pipe joint 27 of the flushing pump 21. One end of the flushing pump water inlet pipe 22 is connected to the flushing pump water inlet pipe joint 26 of the flushing pump 21.

[0036] When washing, the Gerber fat tester fixing and washing frame is placed with the mouth of the Gerber fat tester upward. The bottle plug is removed. The flushing capillary tubes 25 are sequentially inserted into the heart bubble bottom of the Gerber fat tester A. The flushing pump 21 is opened and reversed. The sample and the reagent mixture in the Gerber fat tester A are drawn into the waste liquid bottle. If there is waste liquid in the pipe and cannot be emptied, the joint of the double-head tower joint 24 and the flushing pump water outlet pipe 23 is pulled off. One end of the flushing pump water outlet pipe 23 is inserted into clean water to clean the pipeline. Then, the joint of the double-head tower joint 24 and the flushing pump water outlet pipe 23 is connected. The flushing pump 21 is closed. The Gerber fat tester fixing and washing frame is placed horizontally in the washing basin. The flushing pump water inlet pipe 22 is inserted into the water bath equipment. The flushing pump 21 is opened and forward rotated. The inner wall of the Gerber fat tester A is flushed with water with high temperature in the water bath. Then, the flushing pump water inlet pipe 22 is inserted into the detergent liquid, clean water and tertiary water respectively to flush the inner wall of the Gerber fat tester A until it is clean.

[0037] When the above flushing cannot achieve the cleaning requirement, only need to reverse the flushing pump 21, the inside liquid of gurley A is emptied, the flushing pump 21 is rotated to the chrome acid washing liquid into gurley to full, place 24 hours, use the flushing pump 21 to draw the chrome acid washing liquid and carry out recovery, then use three-stage water to clean to clean.

[0038] The above only is the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation, or only material change, directly or indirectly used in other related technical fields under the inventive concept of the utility model, the contents of the specification and the drawings of the utility model are included in the patent protection range of the utility model.
