Background technology
Move liquid rifle as a kind of pipettor, be all widely used in every field such as chemistry, biology, pharmacy, environment, in laboratory on a small quantity or the pipetting of micro liquid. But, there is certain problem with the connection moving liquid rifle in existing shifting liquid rifle head, such as: 1. stopping property is good not, leakage occurs, poor accuracy affects experimental result; 2. need to use certain dynamics could closely block jail with shifting liquid rifle, pin with hand and move liquid rifle head toward moving on liquid rifle with strength by maybe shifting liquid rifle being put into rifle head, all can cause the heavy wear of shifting liquid rifle, and the former also can cause crossed contamination; 3. when unloading shifting liquid rifle head, only relying on the thrust moving liquid rifle not unload, need to pull up by another hand, one is cumbersome, and two also can cause crossed contamination.
The problems referred to above have to be solved.
Chinese patent CN203108556 discloses a kind of bayonet socket formula and moves liquid rifle head, and head comprises shifting liquid rifle head body, is provided with at least one protruding in the upper end sidewall moving liquid rifle head, thick bottom the top thin of described projection. It is simple that this bayonet socket formula moves liquid rifle header structure, it may also be useful to convenient, to shifting liquid rifle without abrasion. Though but this kind moves liquid rifle head to be solved and move the difficulty insertion of liquid rifle, the problem pulled up of difficulty, but stopping property can be affected due to projection, still there will be leakage problem, and during imbibition, firmly too quickly, draws fluid can be moved in liquid rifle, cause crossed contamination.
A kind of shifting liquid rifle header structure with filter core disclosed in Chinese patent CN102921482, though can effectively prevent liquid from entering shifting sap cavity, but in actually operating, filter core is easy to be in liquid level contact position, and especially when drawing the liquid of maximum capacity, such filter core will touch liquid, thus absorbing fluid, decrease the original amount of liquid, make the liquid measured on the low side, affect experimental result.
Practical novel content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, and the utility model provides a kind of novel antifouling dye to move liquid rifle, by increasing sealing equipment, strengthens that the card between rifle head and rifle body is right and stopping property, preventing pollution; Add the film of strong sorption, many one layer of protections, it is easy to disassembly, cleaning and reusable.
The technical solution adopted in the utility model is: a kind of novel antifouling dye moves liquid rifle, comprise rifle body and it is arranged on the rifle head of the lower end of rifle body, also comprise the tightness system between rifle body and rifle head, described tightness system 2 comprises cutting ferrule, in the rubber inner wall of cutting ferrule inwall in compound, and it is positioned at cutting ferrule and the removable membrane that arranges in turn along cutting ferrule normal direction and bayonet socket from top to bottom, the bayonet socket place uniform multiple projection of circumference; The outside screw that the top of described cutting ferrule is provided with described rifle body is connected; The top of described rifle head is provided with a circle and described projection joins the boss of dress, when rifle head is connected with tightness system, and rubber inner wall and rifle head resilient seal.
Described boss and protruding contact surface are set to corresponding scarp, rotate rifle head and projection can be made to engage with boss.
Described removable membrane is the circular sponge with strong sorption.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantage: the utility model scheme, by increasing dye sealing equipment, strengthens that the card between rifle head and gun barrel is right and stopping property, preventing pollution; Add the film of strong sorption, many one layer of protections, it is easy to disassembly, cleaning and reusable, improve stopping property, accuracy and the work-ing life of moving liquid rifle on the whole.

Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in accompanying drawing 1 ~ accompanying drawing 3, a kind of novel antifouling dye moves liquid rifle, comprise rifle body 1 and it is arranged on the rifle head 3 of rifle body 1 time end, also comprise the tightness system 2 between rifle body 1 and rifle head 3, described tightness system 2 comprises cutting ferrule 21, in the rubber inner wall 22 of cutting ferrule 21 inwall in compound, and it is positioned at cutting ferrule 21 and the removable membrane 23 that arranges in turn along cutting ferrule 21 normal direction and bayonet socket 24 from top to bottom, bayonet socket 24 place circumference uniform multiple protruding 25; The outside screw that the top of described cutting ferrule 21 is provided with described rifle body 1 is connected; The top of described rifle head 3 is provided with the boss 31 that dress joined by a circle and described protruding 25, when rifle head 3 is connected with tightness system 2, and rubber inner wall 22 and rifle head 3 resilient seal.
The contact surface of described boss 31 and projection 25 is set to corresponding scarp, rotates rifle head 3 and convex 25 can be made to engage with boss 31.
Described removable membrane 23 is for having the circular sponge of strong sorption.
When moving liquid rifle and assembled, rifle head 3 top enters cutting ferrule 21 times ends, and in boss 31 card card inlet 24, owing to bayonet socket 24 arranges some protruding 25, can entering by the interval card between boss 31, now rotating gun head 3 just can make rifle head 3 and tightness system 2 link together. The contact surface of boss 31 with protruding 25 is arranged to inclined-plane, it is possible to making rifle head 3 and tightness system 2 compact siro spinning technology, rubber inner wall 22 is pressed on the outside surface of rifle head 3 to realize positiver sealing. When exiting rifle head 3, direct reverse rotation rifle head 3 both can exit.
