Description
Technical field
The utility model is related to a kind of flask clamping device, more particularly to a kind of flask holder beneficial to flask sealing joint.
Background technology
Flask and condenser pipe are conventional glass apparatus in laboratory, although flask and condenser pipe are respectively provided with ground, can be played
Sealedly effect, but following drawback occurs in laboratory technician in routine use:Experiment needs to keep closed environment, what interface was twisted
It is too loose that gas leakage occurs, it is impossible to ensure the seal of reaction；Stubborn is too tight, and reaction can cause condenser pipe difficult and flask point after terminating
Open, so as to cause the damage of instrument.Traditional flask fixture only serves the effect of fixed support, does not there is sealing function.
The content of the invention
To solve the above problems, the utility model provides a kind of convenient, simple in construction, while being conducive to flask sealing joint
Flask holder.
To achieve these goals, the technical solution of the utility model is as follows：A kind of flask beneficial to flask sealing joint
Folder, including clamping bar 1, the firm connecting clip 2 in the front end of clamping bar 1 constitutes two parts circular arc of chuck 2 in center by being hinged
Axle 7 is hinged, and has spiral through hole 5 in the terminal position of chuck, is closed chuck 2 by rotary screw 3, has recessed in the chuck 2
Rubber sleave 4, the width laminating flask frosted mouthful concave portion of groove are cased with groove 6, groove 6.
As further technical scheme, the width for the rubber sleave 4 being cased with the groove 6 covers flask and its just
His glass apparatus interface section, the simply and easily sealing of glass apparatus interface from the inside ensuring of chuck 2.
The beneficial effects of the utility model are：The utility model is provided with the totally enclosed type chuck 2 of the built-in structure of groove 6,
Simultaneously with the further seal glass tool interface system of rubber sleave 4 of laminating groove 6, fulcrum is provided for flask simultaneously at groove 6,
Play a part of clamping flask.Convenient and simple, multi-use is also beneficial to sealing joint while fixing glass apparatus, tool
There is certain practicality.
Brief description of the drawings
Fig. 1 is the schematic diagram that flask holder chuck wide-angle is opened.
Fig. 2 is the schematic diagram of chuck semi arch section.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, rubber sleave 4 is enclosed on into flask and other glass apparatus interfaces when using, using built in chuck 2
Groove 6 fixes the stability of rubber sleave 4 and glass apparatus, and a whole set of glass is locked using rotary screw 3 and spiral through hole 5
Apparatus, it is ensured that the stability of glass apparatus ensures the seal inside glass apparatus simultaneously.
