Bottom is provided with liquid sucting port.Traditional liquid transfer gun head uses plastic material, is directly seated by the connector of rifle head body during use
It is sleeved in the adapter of liquid-transfering gun.In the detection project may disturbed by plastics leachable, the shifting liquid of plastic material
The use of rifle head will be the most limited, such as in the detection of plasticiser, bisphenol-A, perfluorochemical etc..
Utility model content
This utility model technical issues that need to address: provide a kind of and can be applied to be disturbed by plastics leachable
Liquid transfer gun head in detection project.
For solving the problems referred to above, the technical solution adopted in the utility model is: liquid transfer gun head, including: rifle head body, rifle head
The top of body is connector, and the lower end of rifle head body is fluid suction head, and fluid suction head is the taper that caliber tapers into from top to bottom
Pipe, the bottom of fluid suction head is provided with liquid sucting port, and rifle head body and fluid suction head all use glass material, the connector of rifle head body
Middle sealing is plugged with the transfer tube that plastic material is made, and transfer tube is from top to bottom divided into construction section, body section, lower guiding
Section, the body section of transfer tube stretches in the connector of rifle head body under the guiding of lower guide section, outside transfer tube body section
Wall and the inwall card tightening seal of rifle head body connector, transfer tube is sleeved on outside the adapter of liquid-transfering gun by upper construction section.
Further, aforesaid liquid transfer gun head, wherein, the lower guide section of transfer tube includes being interconnected the most successively
Conical section and flat segments, the caliber of conical section is from top to bottom progressively smaller until identical with flat segments caliber.
Further, aforesaid liquid transfer gun head, wherein, the upper construction section of transfer tube gradually becomes in by body section upwards caliber
Big conical pipe.
Further, aforesaid liquid transfer gun head, wherein, the outer wall of transfer tube body section is additionally provided with installation groove, peace
Being provided with sealing ring in dress groove, sealing ring seals against each other for the inwall with rifle head body connector.
The utility model has the advantages that: the rifle head body of glass material is connected with liquid-transfering gun adapter by transfer tube, and
And all connected by plug in construction between rifle head body, transfer tube and liquid-transfering gun adapter, such structure is the most simply, just
In changing and cleaning, it is often more important that the liquid transfer gun head of this structure can be applied to the detection may disturbed by plastics leachable
In project, as plasticiser, bisphenol-A, perfluoro-compound etc. detect project, thus it is greatly improved the accuracy of testing result with reliable
Property.
Accompanying drawing explanation
Fig. 1 is the structural representation of liquid transfer gun head described in the utility model.
Detailed description of the invention
The utility model is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, liquid transfer gun head, including: rifle head body 1, the top of rifle head body 1 is connector 11, rifle head body
The lower end of 11 is fluid suction head 12.Fluid suction head 12 is the conical pipe that caliber tapers into from top to bottom, and the bottom of fluid suction head 12 is arranged
There is liquid sucting port 13.Rifle head body 1 and fluid suction head 12 all use glass material, use the rifle head body 1 of glass material to answer
In the detection project disturbed by plastics leachable.The connector 11 of rifle head body 1 seals and is plugged with plastic material and makes
Transfer tube 2, transfer tube 2 is from top to bottom divided into construction section 21, body section 22, lower guide section 23.The basis of transfer tube 2
Body section 22 stretches in the connector 11 of rifle head body 1 under the guiding of lower guide section 23, the outer wall of transfer tube 2 body section 22 with
The inwall card tightening seal of rifle head body 1 connector 11, transfer tube 2 is sleeved on outside the adapter of liquid-transfering gun by upper construction section 21.This
In embodiment, the lower guide section 23 of transfer tube 2 includes conical section 231 and the flat segments 232 being interconnected the most successively, cone
The caliber of shape section 231 is from top to bottom progressively smaller until identical with flat segments 232 caliber, and lower guide section 23 uses conical section 231
The structure combined with flat segments 232, serves preferably guide effect, it is simple to transfer tube 2 and the connector 11 of rifle head body 1
Between be tightly connected.Meanwhile, in the present embodiment, the upper construction section 21 of transfer tube 2 becomes larger in by body section 22 upwards diameter
Conical pipe, such structure can significantly facilitate transfer tube 2 and liquid-transfering gun adapter between connection.Additionally, transfer tube 2 body
