Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The embodiment of the invention provides a test tube flip device, and a suitable plug cap 1 consists of a plug head 2, a lantern ring 3 and a connecting part 4 for connecting the plug head and the lantern ring, and can refer to fig. 3. The whole elastic material that all adopts of gag 1, if rubber makes, establish the 5 mouthful outsides of test tube with lantern ring 3 cover during sealed earlier, rely on the elastic force of material self fixed, insert 5 mouths of test tube after making the upset of chock plug 2 through this device again, form to block up sealedly.

Test tube flip device is as shown in fig. 1, fig. 3, including base 6 and the revolving cylinder 7 of setting on base 6, be provided with a roll-over table 8 on revolving cylinder 7's the output shaft, be provided with a fixture on roll-over table 8, by fixture with the lateral wall centre gripping back of chock plug 2, roll-over table 8 drive fixture is rotatory to be predetermine the angle, make chock plug 2 aim at test tube 5 mouth in rotatory back bottom, insert test tube 5 mouth with chock plug 2 through tamponade mechanism at last, form encapsulated situation by the elastic force of chock plug 2.

Since the plug 2 and the collar 3 are horizontal when the plug cap 1 is loaded, the plug 2 needs to be rotated 180 degrees and displaced a distance right above the collar 3 and the mouth of the test tube 5. On this basis, the centre of rotation of the gripping means in this embodiment is not arranged coaxially with the centre of rotation of the flipping table 8, i.e. the gripping means is arranged eccentrically with respect to the flipping table 8. When the overturning platform 8 rotates 180 degrees, the clamping mechanism for clamping the plug head 2 synchronously overturns 180 degrees and simultaneously generates displacement with a certain distance, so that the plug head 2 is just positioned right above the opening of the lantern ring 3 and the test tube 5. When the device is actually debugged, the clamping mechanism can be adaptively adjusted to be arranged at the position of the overturning platform 8 so as to ensure the alignment condition of the plug head 2 after overturning.
