Abstract

The utility model relates to a universal connector of a reagent bottle. The shoulder face of a bottle plug head is sheathed with a bottle cover, and the small end of the bottle plug head is tightly matched with a bottle joint. The bottle is provided with ladder-shaped holes which are communicated with each other. One ladder-shaped hole is communicated with the central through hole of the bottle plug head. The utility model can match with the general reagent bottle and has the advantages of good sealing, convenient operation, no need for transferring the reagent; the old reagent bottle is screwed off and the new reagent bottle needs to be changed. The penetration of toxic gas and the moisture inside the reagent can be reduced. The utility model can influence the health of operators and the quality of the reagent.

Description

A kind of common reagent bottle connector

The utility model relates to a kind of connector of reagent bottle.

Using the volumetric method karl Fischer moisture determination instrument, potentiometric titrimeter, the amperometric titration instrument, during instrument such as photometric titrator and solution dispenser, generally all reagent to be moved in the reagent bottle that instrument disposes, in this process, poisonous or have flavor or harmful escaping gas to overflow in the reagent, health to operating personnel has certain influence, and airborne all gases and moisture content etc. also can enter reagent, influence the quality of reagent.

The purpose of this utility model is: design a kind of good airproof performance, the common reagent bottle connector that can be complementary with the common reagent bottle can overcome the problem that exists in the background technology.

For achieving the above object, the technical solution adopted in the utility model is: it is included on the circular bead surface of bottle stopper head and is with bottle cap, the small end of bottle stopper head and bottle graft head closely cooperate, have two stepped bore in the bottle graft head and be interconnected, one of them stepped bore directly is communicated with bottle stopper head central through hole.Also can be with the O RunddichtringO respectively on the roundlet cylinder on bottle stopper head circular bead surface and on the great circle cylinder below the circular bead surface, keep certain clearance between O RunddichtringO above the bottle stopper head circular bead surface and bottle cap hole, formation is rotatably assorted.Perhaps on the bottle stopper head roundlet cylinder of bottle cap upper surface and on the great circle cylinder below the circular bead surface, be with the O RunddichtringO respectively.

The utility model is compared with background technology, and the useful effect that is had is:

1. it can be complementary with general reagent bottle, need not special-purpose reagent bottle;

2. adopt this common reagent bottle connector, when trial-production in the bottle uses up, as long as screw off old reagent bottle, change the novel agent bottle and get final product, need not transfering reagent, easy to use, and can reduce the intrusion of the effusion of toxic gas in the reagent and moisture content etc., influence operating personnel's the health and the quality of reagent;

3. it and reagent bottle, conduit, the connection of drying tube, all with the sealing of O RunddichtringO, the whole system sealing is good.

Description of drawings:

Fig. 1, structural representation of the present utility model;

Fig. 2, another kind of structural representation of the present utility model;

Fig. 3, first kind of embodiment of the present utility model;

Fig. 4, second kind of embodiment of the present utility model;

Fig. 5, the third embodiment of the present utility model.

As shown in Figure 1 and Figure 2, be with bottle cap 3 on the circular bead surface of bottle stopper head 1, bolt on bottle stopper head 1 small end and the screw on the bottle graft head 4 closely cooperate, and have two stepped bore a, b in the bottle graft head 1 and are interconnected, and stepped bore a directly is communicated with bottle stopper head 1 central through hole c.In order to make the coupling part more airtight, can on the roundlet cylinder above bottle stopper head 1 circular bead surface and on the great circle cylinder below the circular bead surface, be with O RunddichtringO 5,2 respectively, O RunddichtringO 5 keeps certain clearance with bottle cap 3, rotate bottle cap 3, the screw on the bottle cap 3 can be complementary with general reagent bottle.Perhaps on the bottle stopper head roundlet cylinder of bottle cap 3 upper surfaces and on the great circle cylinder below the circular bead surface, be with O RunddichtringO 5,2 respectively, after bolt on bottle stopper head 1 small end and the screw on the bottle graft head 4 closely cooperate, bottle cap 3 can be pressed on the circular bead surface of bottle stopper head 1, become as a whole, rotate bottle, the screw on the bottle cap 3 can be complementary with general reagent bottle.

As Fig. 3 is to first kind of embodiment of karl Fischer reagent bottle in the volumetric method karl Fischer moisture determination instrument, connector of the present utility model is screwed on the bottleneck of dress karl Fischer reagent, conduit 7 is inserted into reagent bottle 6 bottoms by a hole of bottle graft head 4, the c hole of bottle stopper head 1, and making sealing and fixing between conduit 7 and the bottle graft head 4 with pipe joint 8 and O RunddichtringO 9, another hole b of bottle graft head goes up fixedly drying tube 10.With 11 sealings of O RunddichtringO, reagent bottle 6 must communicate with atmosphere by drying tube 10, prevent the effusion of toxic gas and the intrusion of moisture content, the other end of conduit 7 is connected with gauge line through the plane valve, during the gauge line descent of piston, karl Fischer reagent is inhaled in the gauge line, when karl Fischer reagent uses up,, change new karl Fischer reagent bottle 6 and get final product as long as unload empty karl Fischer reagent bottle 6, need not to shift karl Fischer reagent, reduced the effusion of toxic gas and the intrusion of moisture content.

Fig. 4 be in the volumetric method karl Fischer moisture determination instrument to second kind of embodiment of solvent bottle, reagent bottle connector and solvent bottle, conduit, the connection of drying tube is same as shown in Figure 3.Electronic barrier film inflator pump is joined through the upper end of conduit 12 with drying tube 10, and with pipe joint cap 13 and O type circle 14 sealing and fixing, when starting electronic barrier film inflator pump, through conduit 12, drying tube 10, the hole of bottle graft head 4b, bottle stopper head 1 central through hole c inflates in solvent bottle 15, solvent is extruded from the conduit 7 that inserts solvent bottle 15 bottoms, inject reaction cup.

Fig. 5 is to the third embodiment of waste liquid bottle in the volumetric method karl Fischer moisture determination instrument, reagent bottle connector and solvent bottle, conduit, the connection of drying tube is also same as shown in Figure 3, electronic barrier film aspiration pump is joined through the upper end of conduit 12 with drying tube 10, and with pipe joint cap 13 and O type circle 14 sealing and fixing, when starting electronic barrier film aspiration pump, through conduit 12, drying tube 10, the b hole of bottle graft head 4, bottle stopper head 1 central through hole c bleeds in waste liquid bottle 18, with extracting out in the conduit 7 of waste liquid through inserting reaction cup 16 bottoms, enter in the waste liquid bottle.
