Description
Technical field
The utility model relates to surveying instrument field, furtherly, relates to a kind of glass density meter clamping device.
Background technology
Adopt hydrostatic weighing method to examine and determine/calibrate glass density timing, need to control densitometer scale mark and arrive the position of specifying, in whole process, needing to keep this position motionless.Due to need to obtain densitometer in air with liquid-working-medium in mass value, also need to make to grip the very little measuring process that do not affect of densitometer device mass change, its mass change is negligible.
Because glass density meter belongs to thin-walled breakaway glass instrument, especially main part, general wall thickness, all much smaller than 1mm, is subject to the impact that external force is inhomogeneous or little all can make the damaged fracture of main cause densitometer to damage.Adopted bungee to be wound around in the time that friction force is enough large and then densitometer to be hung below balance with messenger wire connection bungee in densitometer main top (without scale mark part) part multi-turn in the past, this method is difficult to guarantee that densitometer position does not change in weighing, and in the time that actuating medium is volatile organic liquid, aging, fracture that bungee can occur, cannot guarantee measured densitometer safety thereby cause densitometer to come off; In the time being wound around densitometer and unclamping, cannot guarantee that the quality of this part bungee remains unchanged simultaneously.
Utility model content
For solving the problem occurring in prior art, the utility model provides a kind of glass density meter clamping device.Simple in structure, easy operating, and firmly guarantee safety and in measuring process, keep oeverall quality constant in measuring process clamping.
The purpose of this utility model is to provide a kind of glass density meter clamping device.
Comprise:
Hanging part, sleeve pipe and nut;
Described hanging portion is divided into barrel-like structure, and outer wall is provided with screw thread, and hanging part top is provided with suspension hook, and the inwall of tubbiness opening one end is the groove that has tapering; Tapering does not have angle requirement, conventionally between 30-50 degree.
One end opening of described sleeve pipe is taper, and the external diameter of sleeve pipe matches with the tubbiness internal diameter of hanging part, and the internal diameter of sleeve pipe matches with the main external diameter of glass density meter;
An end opening is sealed in nut one end, and opening one end is provided with internal thread, and sealing one end is provided with through hole, and through hole internal diameter is greater than the main external diameter of glass density meter;
Sleeve pipe is inserted in hanging part, and cap nut, by screw thread and hanging partial fixing.
The internal diameter of sleeve pipe is larger than the glass density meter dry tube diameter of required clamping, and be mainly main can be stretched in sleeve pipe, and gapped can movement, but cannot be fastening can not cross ambassador and screw nut time.Therefore general preferred large 0.1mm～0.8mm, sleeve pipe evenly arranges 4-6 bar vertical slot with the top of tapering.
The through-hole diameter size of nut one end is to be mainly convenient to densitometer main insert, as long as can enter.So the large 0.3mm of diameter arrives 1mm above can.Crossing conference location is not easy.
The material of hanging part and nut is metal, and the material of sleeve pipe is teflon.
The utility model specifically can be by the following technical solutions:
The suspension hook of hanging part is for being connected clamping device to be convenient to weigh with the connecting link of balance below together with densitometer, the lower end external thread of hanging part is connected with the internal thread of nut when stretch in the hole of hanging part appropriate location when sleeve pipe and densitometer, hangs diameter of bore partly and equates with the external diameter of sleeve pipe.
The internal diameter of sleeve pipe is than the large 0.2mm of densitometer dry tube diameter of required clamping, and sleeve pipe evenly has 4-6 bar vertical slot with the operative tip of tapering, can make like this cannula tip produce certain gap, is convenient to glass density meter main and enters; Can play the effect of clamping glass densitometer main simultaneously.One end of nut, with internal thread, can be connected with the lower end external thread of hanging part, and the opening diameter of one end, than the large 1mm of dry tube diameter, is convenient to densitometer main and is passed through.
When use, glass density meter main is stretched into the Kong Zhonghou of nut, again by casing pipe sleeve on glass density meter main, when required glass density meter main part stretches into after sleeve pipe, sleeve pipe and densitometer are inserted in hanging part, and then screwing nut will be connected with hanging, constantly rotate by screw thread, sleeve pipe lower end produces enough large friction force to glass density meter, when densitometer the is stable nut that can stop the rotation while not being subjected to displacement.
This apparatus structure is simple, and hanging part and nut are metal manufacture, and sleeve pipe is teflon manufacture, corrosion-resistant, and therefore erecting by overhang total quality can not change in measuring process.
