Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the preferred embodiment of the laboratory filtration bottle interface device of the present invention comprises a connecting pipe 100 and a flaring mechanism 200, wherein the flaring mechanism 200 is used to enlarge the opening of one end of the connecting pipe 100 connected to the filtration port, so as to fix the connecting pipe 100 on the filtration port of the filtration bottle.

Referring to fig. 3, the connection tube 100 includes a tube mouth 1 and a tube body 2, the flaring mechanism 200 is disposed on the tube mouth 1, and the flaring mechanism 200 is used for locking the tube mouth 1 on a filtration mouth of a filtration bottle; the tube body 2 is used for connecting a vacuum tube. The pipe orifice 1 is made of materials with elastic stretching, such as rubber, and the like, so that the flexibility of the pipe orifice 1 can be used for adapting to the filtering ports of filtering bottles with different sizes. The inner wall of the pipe orifice 1 is provided with anti-skidding teeth 11 for increasing friction force, so that the pipe orifice 1 can be better fixed on a suction filtration port.

The pipe body 2 comprises a plurality of connecting bodies 21 which are spliced one by one, and each pipe body 2 is provided with a sealing ring 22 to ensure good sealing with the vacuum pipe; the upper end of each connecting body 21 has a splicing ring 23, the lower end of the connection has a splicing step 24, and the splicing ring 23 is inserted into the splicing step 24 on the adjacent connecting body 21, thereby connecting the adjacent two connecting bodies 21. Be equipped with protruding 26 on the concatenation ring 23, be equipped with recess 25 on the concatenation step 24, protruding 26 and recess 25 cooperation can effectually be consolidated adjacent two connectors 21 and be connected, avoid droing. The diameter of the upper end of the connecting body 21 is larger than that of the lower end of the connecting body 21, so that the connecting body 21 can adapt to vacuum tubes of different sizes.

The flaring mechanism 200 comprises a shell 3 and a fixing cap 4, wherein the fixing cap 4 is screwed on the shell 3, and the fixing cap 4 presses the pipe orifice 1 on the shell 3. Be equipped with the recess on the shell 3, the recess is used for cooperating with mouth of pipe 1, increases mouth of pipe 1's stability. The fixing cap 4 is provided with an anti-drop ring 41, and the anti-drop ring 41 is abutted against the end face of the shell 3, so that the stability of fixing the pipe orifice 1 is improved. The pipe orifice 1 is pressed on the shell 3 by the fixing cap 4, the front end of the pipe orifice 1 is trumpet-shaped, so that a suction filtration port can be conveniently inserted into the pipe orifice 1, and the use is convenient.

As shown in fig. 4, in use, the nozzle 1 is fitted over a filtration port (not shown) of a filtration bottle, and the nozzle 1 is fixed to the filtration port by the elasticity of the nozzle 1. The pipe orifice 1 is made of elastic materials and can deform to the diameter suitable for the filtering orifices with different sizes so as to adapt to the filtering orifices with different sizes.
