Abstract
The utility model relates to a fixing frame for a volumetric flask for determining the content of amylose in rice and belongs to an agricultural product detection instrument. In the fixing frame, support frame screw rods are assembled at four corners of a bottom plate with volumetric flask seat holes and water supply holes; an upper plate for fixedly arranging a frame type elastic sealing gasket and a frame type clamping plate is configured on the support frame screw rods; elastic sealing sleeves and the volumetric flask seat holes on the bottom plate are vertically and coaxially assembled on the upper plate; height adjusting nuts and elastic locking clips are installed on the support frame screw rods; the height adjusting nuts are positioned below the frame type clamping plate; and the elastic locking clips are positioned above the upper plate. With the adoption of the fixing frame, a plurality of volumetric flasks are orderly, reliably and fixedly configured in an electric heating thermostatic water bath kettle to finish the determination operation of the content of the amylose; and the fixing frame has the characteristics of simple structure, low cost, convenience and reliability in use, strong applicability, good detection quality and high work efficiency.
Description
Technical field
The invention belongs to the agricultural product quality detecting instrument, relates generally to a kind of and the matching used detection part of electric-heated thermostatic water bath.
Background technology
According to the GB7648 of Ministry of Agriculture method improvement method for simplifying, need the 100ml volumetric flask be put during content of amylose in rice is measured and boil 10min in the boiling water bath, be cooled to adding distil water constant volume after the room temperature then.In the process that volumetric flask places water-bath to boil, volumetric flask can run-off the straight, even if with rubber band be, high temperature also can be caused danger, and serious meeting is toppled over, and then causes the water in the water-bath to flow in the volumetric flask, can have a strong impact on result of experiment like this.In addition, it also is very inconvenient boiling the volumetric flask that takes out high temperature in the back, and operability is very poor.
Summary of the invention
The purpose of the invention is exactly the problem that exists to above-mentioned prior art; Design provides a kind of content of amylose in rice to measure the volumetric flask fixed mount; This fixed mount and volumetric flask, electric-heated thermostatic water bath are used, and reach the purpose that realizes stationary positioned, raising accuracy of measurement and the detection efficiency of content of amylose in rice mensuration volumetric flask in electric-heated thermostatic water bath.
The basic design of the invention is; The corresponding respectively equipped support screw at base plate four corners position place; On base plate, be provided with volumetric flask seat hole and last water hole, on the bottom side of upper plate, dispose frame elastic sealing gasket and frame clamping plate from top to bottom successively, through securing member elastic sealing gasket and frame clamping plate are packed on the upper plate bottom surface and are integral; Four support screws are inserted in successively in frame clamping plate, frame elastic sealing gasket and the upper plate upper plate are configured in the base plate top; Volumetric flask seat hole on elastic seal cartridge and the base plate is being fitted on the upper plate of concentric up and down, equipped height adjusting nut and elastic locking folder on support screw, and described height adjusting nut is positioned at frame clamping plate below; And with frame clamping plate contact matching; Described elastic locking folder is positioned at the upper plate top, and with the upper plate contact matching, so far constitute content of amylose in rice and measure the volumetric flask fixed mount.
The invention can be a plurality of volumetric flasks in order and the configuration of secure fixation is placed in the mensuration operation of accomplishing content of amylose in rice in the electric-heated thermostatic water bath, has the advantages that novel structure is simple, cheap for manufacturing cost, easy to use and reliable, the ability that is suitable for is strong, detect that quality is good, operating efficiency is high.

The specific embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.A kind of content of amylose in rice is measured the volumetric flask fixed mount; The corresponding respectively equipped support screw 7 at base plate 1 four corners position place; On base plate 1, be provided with volumetric flask seat hole 9 and last water hole 10; On the bottom side of upper plate 5, dispose frame elastic sealing gasket 4 and frame clamping plate 2 from top to bottom successively, through securing member elastic sealing gasket 4 and frame clamping plate 2 are packed on upper plate 5 bottom surfaces and are integral, four support screws 7 are inserted in successively in frame clamping plate 2, frame elastic sealing gasket 4 and the upper plate 5 upper plate 5 are configured in base plate 1 top; Volumetric flask seat hole on elastic seal cartridge 8 and the base plate 1 being fitted on the upper plate 5 of concentric about in the of 9; Equipped height adjusting nut 3 and elastic locking folder 6 on support screw 7, described height adjusting nut 3 is positioned at frame clamping plate 2 belows, and with frame clamping plate 2 contact matching; Described elastic locking folder 6 is positioned at upper plate 5 tops, and with upper plate 5 contact matching.
When measuring the operation use; The volumetric flask neck part that paddy rice ground rice and reactant liquor are housed upwards inserted from downside be fitted in the trepanning of elastic seal cartridge 8, the bottom of volumetric flask is seated on the volumetric flask seat hole 9, rotates height adjusting nut 3; Change its high and low position on support screw 7; Upper plate 5 is pressed against volumetric flask through elastic seal cartridge 8 on the volumetric flask seat hole 9 of base plate 1 locatees overall fixed,, this fixed mount integral body is placed in the electric-heated thermostatic water bath gets final product with the fixing position of upper plate 5 on pole screw rod 7 of elastic locking folder 6 restrictions; Hot water in the pot floods heating from last water hole 10 with the volumetric flask bottom side; Hot water can also directly heat through 9 pairs of volumetric flask bottoms, volumetric flask seat hole in the pot simultaneously, improves the efficiency of heating surface, accomplishes testing.
