Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment：A kind of acid buret, as shown in figure 1, including interconnected body 3 and cock set 4, body 3 wraps
Include hot melt and be fixed on the feed tube 32 that cock covers 4 upper ends, graduated scale 31 is stained with feed tube 32.
After titrating solution enters feed tube 32, the capacity of titrating solution in feed tube 32 can be measured by graduated scale 31,
Avoid the amount of titrating solution inaccurate and influence experimental result.
Connecting tube 1 is threaded with the lower end of cock set 4, the lower end of connecting tube 1 is threaded with sharp nozzle tube 2.
, can be by sharp nozzle tube 2 from connecting tube 1 after the vaseline smeared on cock set 4 is flowed into connecting tube 1 and sharp nozzle tube 2
Turn and remove, then connecting tube 1 is turned from cock set 4 and removed, body 3, which is split into after three sections, to be respectively washed will easily manage
The vaseline of the inwall of body 3 washes.
As shown in Fig. 2 cock set 4 includes fixing pipe 42, fixing pipe 42 heats the lower end for being fixed on cock set 4, in fixation
The first external screw thread 41 is offered on pipe 42 and on outer wall, is opened in connecting tube 1 close to one end of cock set 4 and on inwall
Provided with the first internal thread 11, the first external screw thread 41 be threadedly coupled with the first internal thread 11 so that connecting tube 1 and fixing pipe 42 each other
It is fixed.
Connecting tube 1 is threadedly coupled with fixing pipe 42 can pull down connecting tube 1 cleaning, simple to operate.
In the upper end of connecting tube 1, hot melt has the first elastic seal ring 14, and the first elastic seal ring 14 uses rubber；
The outer diameter of fixing pipe 42 is more than the external diameter of the first external screw thread 41, therefore therefore both junctions form step surface
43, the step surface 43 is contradicted on the first elastic seal ring 14, the first elastic seal ring 14 be clamped in the upper end of connecting tube 1 with
Between step surface 43 so that fixing pipe 42 has good dense water energy with the junction of connecting tube 1.
When connecting tube 1 is threadedly coupled with fixing pipe 42, connecting tube 1 is stabilized under the effect of the elastic force of the first elastic seal ring 14
In fixing pipe 42, reduce connecting tube 1 and rotate and come off automatically when being acted on by external force.
As shown in Figure 3 and Figure 4, the lower end of connecting tube 1 includes integrally formed slip ring 12；The inside and outside wall of slip ring 12 is put
Between inside and outside the connecting tube 1, slip ring 12 and the junction of connecting tube 1 form step end；
The second external screw thread 13 is offered on the outer wall of slip ring 12.
Towards one end of connecting tube 1 and at outer wall, hot melt is fixed with the first annulus 21, the heat at inwall to sharp nozzle tube 2
Molten to be fixed with the second annulus 22, the first annulus 21 and the second annulus 22 are highly identical.
The second internal thread 23 is offered on the inwall of first annulus 21, is provided with and supplies between the first annulus 21 and the second annulus 22
The chute 24 that slip ring 12 screws in, chute 24 are annular shape.
The upper surface of second annulus 22 is the second cambered surface 26, and the second cambered surface 26 is arcwall face, and the second cambered surface 26 is inside from outer ring
Circle is obliquely installed.
The lower inclination of second cambered surface 26 so that have gap between the second annulus 22 and two ends of connecting tube 1, reduce
Second annulus 22 and the probability of the end of connecting tube 1 collision.
Second cambered surface 26 is obliquely installed, and is easy to the landing of liquid, is easy to cleaning of the later stage to the second annulus 22.
The upper end hot melt of first annulus 21 has the second elastic seal ring 27, when connecting tube 1 is threadedly coupled with sharp nozzle tube 2,
Sharp nozzle tube 2 is stabilized in connecting tube 1 under the effect of the elastic force of the second elastic seal ring 27.Second elastic seal ring 27 is by rubber system
Into, that is to say, that due to the presence of the second elastic seal ring 27, connecting tube 1 and the extruding of 2 two ends of sharp nozzle tube are squeezed for elasticity
Pressure, reduce connecting tube 1 and sharp nozzle tube 2 because screw power it is excessive and caused by it is damaged.
Sharp nozzle tube 2 is avoided to rotate and come off automatically when being acted on by external force.
The brake pad 25 of multiple outwardly convexs is provided with the circumferencial direction of the outer wall of sharp nozzle tube 2, the lug boss of brake pad 25 is
Sphere, brake pad 25 divide for two rows.
When turning the sharp nozzle tube 2 of small volume, brake pad 25 can increase the frictional force of sharp nozzle tube 2 and hand, conveniently turn point
Mouth pipe 2.
After debris enters connecting tube 1 with sharp nozzle tube 2, sharp nozzle tube 2 can be turned from connecting tube 1 and removed, then will even
Adapter 1 is turned from cock set 4 and removed, and is respectively washed after body 3 is split into three sections.
Embodiment 2, its difference with embodiment 1, as shown in figs. 5 and 6, the bottom of chute 24 is placed with draw ring
51, the annulus 22 of draw ring 51 and second, the first annulus 21 are that gap coordinates；It is not perishable and pull bar is made up of rigid plastics.Draw
The circumferencial direction hot melt of ring 51 has four drawstrings being equally spaced 52, and the upper end heat of drawstring 52 is placed on the hole of the second annulus 22
In.
The outer wall of second annulus 22 offers axial metallic channel 53, and guide groove is embedded in for drawstring 52, revolved to slip ring 12
When entering chute 24, slip ring 12 is difficult to contact with metallic channel 53.
When needing cleaning, draw ring 51 is taken out from chute 24 by four drawstrings 52 of drawing, during draw ring 51 pulls out,
By the foreign body between the bottom of chute 24 and side wall, cleaning efficiency is improved.
Draw ring 51 can hold draw ring 51 so that draw ring 51 slowly slips into when placing in chute 24 by an outer bar
The bottom of chute 24.
