Description

A kind of new liquid transfer gun head
Technical field
The utility model is related to a kind of new liquid transfer gun head.
Background technology
In bio-pharmaceuticals experiment, the medicine that can be usually related to transfer liquid is tested, the process shifted in decoction In often use some relatively simple liquid-transfering devices such as glue head dropper, can be also applied in advanced scientific experiment The quantitative liquid-transfering gun of some specialty liquids, during decoction is drawn, liquid-transfering gun is pressed into using the principle of draught head by decoction In head, and during pipette tips are pressed into, liquid-transfering gun control is bad, and the phenomenon of liquid backflow often occurs, so as to cause to move The accuracy of the failure of liquid, indirectly influence experimental data.Sealing is there is also during conventional liquid transfer gun head liquid relief not It is good, cause the phenomenon of leakage to occur, be also easy to cause body and other objects in various degree after mordant decoction drippage Destruction, so the design of liquid transfer gun head is most important.
Utility model content
The utility model device is a kind of new liquid transfer gun head, is carried out also with the principle of pressure differential during liquid relief Liquid relief, pipette tips are sealed by way of sealing ring, it is ensured that good sealing and anti-return is devised in pipette tips Device, can effectively prevent liquid from flowing back and damage is caused to liquid-transfering gun.
The technical solution adopted in the utility model is:A kind of new liquid transfer gun head, including:Fluid suction head, liquid storage pipe, anti-return Room, female connector, spin locking card, liquid-transfering gun connector and sealing ring, the lower end of liquid storage pipe are connected with fluid suction head, the upper end of liquid storage pipe It is connected with above anti-return room, anti-return room and is connected to female connector, female connector links installation, female connector and liquid relief with liquid-transfering gun connector Rifle connector is by each going up the fluid suction head on the spin locking card progress locking fastening in pipette tips, liquid transfer gun head, liquid storage pipe, preventing Return passage, female connector, spin locking card are integral structure, and the inside of described female connector is equipped with sealing ring, ensure that in peace Whole device has certain sealing during liquid relief after dress.
The beneficial effects of the utility model:1. the product of the utility model height meter, the conical design of fluid suction head can be in depth It is more prone to when entering container, is virtually improving operating efficiency, the overstriking design of liquid storage pipe can be in the same of quantitative liquid relief When, additionally it is possible to increase the size of liquid relief amount, strong applicability.2. the product of the utility model height meter, the design of anti-return, Neng Gou When also there is negative pressure in liquid storage pipe when needing not continue to imbibition, space compensation is carried out using air, liquid can temporarily flow to anti- Stored in return passage, after compensated with air, pressure differential is not present, the operation of liquid relief discharge opeing can be normally carried out.3. a practicality Being designed to of sealing ring design and spin locking card in the product of new high meter, female connector ensures sealing in use Property, the phenomenon of leakage and dropping liquid will not occur during liquid relief.4. the product of the utility model height meter, from overall structure On optimize liquid transfer gun head various deficiencies in use.
Brief description of the drawings
Fig. 1 is the utility model product overall structure diagram.
Fig. 2 is the utility model product front view.
Embodiment
Present embodiment is described further according to Fig. 1, Fig. 2.
A kind of new liquid transfer gun head, including:Fluid suction head 1, liquid storage pipe 2, anti-return room 3, female connector 4, spin locking card 5, shifting Liquid rifle connector 6 and sealing ring 7, the lower end of liquid storage pipe 2 are connected with fluid suction head 1, and the upper end of liquid storage pipe 2 is connected with anti-return room 3, The top of anti-return room 3 is connected to female connector 4, and female connector 4 links installation, female connector 4 and liquid-transfering gun connector 6 with liquid-transfering gun connector 6 By each going up the fluid suction head 1 on the progress locking fastening of spin locking card 5 in pipette tips, liquid transfer gun head, liquid storage pipe 2, anti-return Room 3, female connector 4, spin locking card 5 are integral structure, and the inside of described female connector 4 is equipped with sealing ring 7, ensure that in peace Whole device has certain sealing during liquid relief after dress.
Operation principle:
When installing and using, whole pipette tips part is aligned to the head of liquid-transfering gun, female connector 4 is enclosed on liquid-transfering gun connector 6 On, until being enclosed on root, liquid-transfering gun connector 6 is contacted with the sealing ring 7 inside female connector 4, be rotated further by whole pipette tips structure, make Spin locking card 5 is placed in lock-out state.Complete the operation of installation.In liquid relief, first with liquid-transfering gun by inside pipette tips Space is in negative pressure state, and fluid suction head 1 is placed in below liquid level, starts imbibition, internal when liquid absorption is enough to go back When there is negative pressure, now pipette tips can be departed from liquid level, be compensated using air, the liquid now drawn can flow into anti-return room In 3, after pressure is balanced, you can start liquid relief, fluid suction head 1 is placed in container, high pressure is produced using liquid-transfering gun, by pipette tips Liquid is discharged, that is, completes the process and principle of whole pipetting.
The above of the present apparatus describes embodiment of the present utility model, this area by reference to Fig. 1, Fig. 2 Technical staff is it will be appreciated that the utility model product is not limited to embodiment described above, without departing from essence of the present utility model Various modifications may be made in the case of god, and the modification should be also included within the scope of the utility model.The utility model Scope should be limited by appended claims and its equivalent.
