Abstract
It is the hollow symmetrical structure for arc surface of cuboid based on the pedestal the utility model discloses a kind of clamping device prevented small-sized volumetric flask and toppled over, including fixed pedestal；There is one layer of coating on the arc surface, the material of the coating is high intensity rubber-plastic sponge；The pedestal is connected by the identical connecting rod of four sizes, and the connecting rod is slightly longer than Base body, and both ends carry nut and screw thread.It is simple in structure the utility model discloses a kind of clamping device prevented small-sized volumetric flask and toppled over, it is of low cost, it is easy to operate, and be not easy to topple over during use, it can be used in chemical laboratory.
Description
Technical field
The utility model is related to laboratory auxiliary device technical field, specially a kind of clamping prevented small-sized volumetric flask and toppled over
Device.
Background technology
In the research and experiment in laboratory, some small volumetric flasks are often used when preparing solution.Due to volumetric flask
For the flat shape structure of thin neck pyriform, while the constant volume stage for configuring using volumetric flask solution often uses pipette, and liquid relief
Manage long, careless manipulation may fall volumetric flask band, to cause safety accident.
Invention content
The utility model aim is：It designs and a kind of preventing that the clamping device toppled over of small-sized volumetric flask with fixed capacity bottle, prevents
Topple over phenomenon in preparing solution processes.
The utility model provide it is a kind of preventing the clamping device toppled over of small-sized volumetric flask, specifically include two symmetrical pedestals with
For connecting the identical connecting rod of four sizes of pedestal.
Preferably, Base body is cuboid, and the contact surface part of two pedestals is hollow arc surface, and one is covered on arc surface
Floor height intensity rubber-plastic sponge.
Preferably, a height of 4cm of pedestal, a length of 14cm, width 5cm.
Preferably, contact surface is respectively the plane of 2cm and the circle that radius of curvature is 10cm, fan-shaped angle is 60 ° by both ends
Cambered surface forms.
Preferably, the thickness of the high intensity rubber-plastic sponge layer on arc surface is 0.8cm.
Preferably, the length of connecting rod is 16cm, a diameter of 0.8cm；There are nut and the screw thread of 4cm in connecting rod both ends；
Connecting rod is respectively across pedestal at away from pedestal front-back 0.8cm.
The utility model provides a kind of clamping device prevented small-sized volumetric flask and toppled over, simple in structure, of low cost, behaviour
Facilitate, and be not easy to topple over during use, can be used in chemical laboratory.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is pedestal vertical view.
Attached drawing table and explanation：1,2- pedestals, 3,4,5,6- connecting rods, 7- high intensity rubber-plastic sponge layers
Specific implementation mode
As shown in Figs. 1-2, the utility model is a kind of clamping device prevented small-sized volumetric flask and toppled over, including two symmetrical pedestals
1,2, Base body is rectangular-shape, and the middle section of two base contact faces is hollow, and hollow space is two symmetrical arc surfaces.
Pedestal avoids toppling over phenomenon during volumetric flask use to fixed and clamping volumetric flask the flat place's structure of pyriform.
Described device further includes the identical band screw connection bar of four sizes 3,4,5,6.Connecting rod to connect two pedestals,
Two pedestals are made to be linked to be an entirety in use to play fixed function.
Further, a height of 4cm of pedestal, a length of 14cm, width 5cm, contact surface by both ends be respectively 2cm plane and
The arc surface composition that radius of curvature is 10cm, fan-shaped angle is 60 °.In this way, described device can match in more specification low capacity bottles
It is used when solution processed.
Further, the high intensity rubber-plastic sponge layer that a layer thickness is 0.8cm is covered on the hollow arc surface of two pedestals, is used
With the wall surface of Protection capacity bottle in use, base part is avoided to scrape volumetric flask.
Further, the length of connecting rod is 16cm, a diameter of 0.8cm；There are nut and the spiral shell of 4cm in connecting rod both ends
Line；Connecting rod is respectively across pedestal at away from pedestal front-back 0.8cm.In this way, connecting rod can not destroy high intensity rubber and plastic
Connection function is played while sponge coating；Meanwhile both ends are provided with nut that whole device can be fixed into an entirety,
Prevent volumetric flask from thering is described device when toppling over trend not fallen to fix in volumetric flask by band.
First the same side whole screw is removed when use, two pedestals are opened, volumetric flask are put into the hollow structure of pedestal
In, so that two pedestals is drawn close to centre to clamp volumetric flask bottom, then will be in the screw means to connecting rod that removed, you can steady
Surely volumetric flask is lived, prevents it from toppling in use.
The utility model provides a kind of clamping device prevented small-sized volumetric flask and toppled over, simple in structure, of low cost, behaviour
Facilitate, and be not easy to topple over during use, can be used in chemical laboratory.
Specific implementation mode described in the utility model does not constitute the limitation to the application range, all in the utility model
Within the spirit and principle of design, all any modification, equivalent and improvement etc. that one of skill in the art can make should all
It is included within the scope of protection of this utility model.
