A kind of flask for preventing that bottle stopper from coming off
The utility model is related to a kind of chemical experiment apparatus, and in particular to a kind of flask for preventing that bottle stopper from coming off.
Flask is to be used in laboratory contain liquid substance and one kind available for heating has neck glassware.At present, burn
Sealed more than bottle bottleneck using ground bottle stopper, due to ground bottle stopper with flask bottle without anti-drop structure, ground bottle stopper is easy to
Come off, particularly when the liquid heating contained in flask, its steam pressure produced is easy to rush de- bottle stopper.When there is a large amount of burnings
When bottle has the same space, bottle stopper is easy to obscure after coming off, and causes solution to pollute, and each flask is to correspond with bottle stopper
, bottle stopper is easy to make flask sealing bad after obscuring, and the phenomenon of leakage occurs.Therefore, in order to avoid bottle stopper is obscured, existing skill
Ground bottle stopper and bottle are often attached by art using rubber band or cotton rope, and the easy aging of rubber band, and bottle stopper is still easy to
Come off, need to carry out the operation such as knot with cotton rope connection, complex operation efficiency is low, influence experimental work, and due to connecting rope
Certain length is still left in order to the opening and shutoff operation of bottle stopper, these connection methods in the centre of connection bottle stopper and bottle
It can only play a part of preventing bottle stopper from losing or obscuring after coming off, it is impossible to preventing the de- bottle stopper of steam pressure punching from playing a role.
Utility model content

Topic, its is simple in construction, easy to operate, quick.
To solve above technical problem, the technical solution of the utility model provides a kind of flask for preventing that bottle stopper from coming off,
It includes bottle stopper and bottle, it is characterised in that：It is horizontally disposed on the bottleneck inwall of the bottle to have annular recess, bottle stopper
Inclined hole and half-via are internally provided with, inclined hole is connected with half-via, inclined hole is located at bottle stopper outer wall and the oblique connection of bottle stopper axis
On line, half-via is located on the axis of bottle stopper, and its bottom is located in bottle stopper, and inclined hole outlet port is higher than half-via bottom, tiltedly
Hole aperture position is corresponding with the annular recess position on bottleneck inwall, and the opening of half-via is located at bottle stopper top surface；The half-via
Inside is fixed with spring, and spring connection support bar, support bar top is provided with fixed buckle and is fixed in half-via opening；
Support bar is provided with the inclined hole, support bar is connected with support bar.
Further, the number of above-mentioned inclined hole is no less than two.
Above-mentioned inclined hole is more preferably selected as in the both sides that half-via is symmetricly set in same level.
Further, the bottle stopper is ground bottle stopper, and bottleneck is had the ground supporting with bottle stopper, connected with ground.
Further, above-mentioned supporting bar top is connected with covering, and covering is made up of the material of flexible deformation nature, plus
Strong outside aesthetic property and the comfort level of operation, while further limit motion of the support bar in half-via, make whole
Motion, which is sealed in inside bottle stopper, not to be released and attractive in appearance.
Further, the spring, support bar and support bar are made up of corrosion resistant inert material, and the selection of its material can
It is changed with the purposes according to flask, prevents the liquid in flask from corroding to it, improves the service life of bottle stopper.
The operation that covers of the utility model bottle stopper is：Pressing down on support bar drives support bar motion support bar is withdrawn tiltedly
Hole, bottle stopper is slowly filled in along bottleneck, unclamps support bar, and under the elastic force effect of spring, support bar stretches out inclined hole and is caught in groove
It is interior, complete covering for bottle stopper；Also support bar can not be pressed down on and rely on the extruding support bar motion of bottleneck inwall to receive support bar
Inclined hole is returned, until support bar is caught in groove, bottle stopper plays sealing function with bottleneck precision-fit, be provided simultaneously with preventing bottle stopper from taking off
The function of falling.
The unlatching of the utility model bottle stopper is operated：Pressing down on support bar drives support bar motion to make support bar from groove
Interior withdrawal inclined hole, bottle stopper is taken out along bottleneck.
Compared with prior art, the utility model is fixed to bottle stopper, can prevent the de- bottle stopper of steam pressure punching, solution
Determined the problem of flask bottle stopper easily comes off in the prior art, thus play the bottle stopper for avoiding bottle stopper from being caused after coming off obscure, it is molten
The problems such as liquid pollution or leakage；Prior art is solved using rubber band or cotton rope connection bottle stopper and bottle, the easy aging of rubber band,
It is low that cotton rope ties up knotting efficiency, opens and stopper the problem of bottle stopper is inconvenient；The utility model fixes the groove of bottle stopper in flask
Set on bottleneck inwall along level orientation, when making the operation of lid plug, bottle stopper can cover tightly bottleneck downwards in any direction, with screw lid plug
Operation is compared, and the operation of the utility model lid plug more facilitates, fast.
Therefore, the utility model is simple in construction, and bottle stopper fixes reliable, difficult for drop-off, and lid plug is easy to operate, quick.

In order that those skilled in the art more fully understands the technical solution of the utility model, with reference to specific implementation
The utility model is described in further detail for mode.
Referring to Fig. 1 to Fig. 3, the utility model provides a kind of flask for preventing that bottle stopper from coming off, and it includes bottle stopper 1 and bottle
2, horizontally disposed on the inwall of bottleneck 3 of the bottle to have annular recess 4, bottle stopper 1 is internally provided with two inclined holes 5 and one
Individual half-via 6, inclined hole 5 is connected with half-via 6, and inclined hole 5 is located at the both sides that half-via 6 is symmetricly set in same level；Tiltedly
Hole 5 is located at bottle stopper outer wall and on the oblique connecting line of bottle stopper axis, half-via 6 is located on the axis of bottle stopper, and its bottom is located at
In bottle stopper, the outlet port of inclined hole 5 is higher than the bottom of half-via 6, the aperture position of inclined hole 5 and the position of annular recess 4 on bottleneck inwall
