Abstract
The utility model relates to a straight-chain starch volumetric flask heating auxiliary device which is characterized by comprising a straight-chain starch volumetric flask clamping plate and a holding rack for holding the straight-chain starch volumetric flask clamping plate, wherein the clamping plate consists of a plurality of clamping strips, two clamping frames and wedged blocks; two types of clamping strips are provided; a plurality of arched concave holes in match with necks of straight-chain starch volumetric flasks are formed in inner sides of the clamping strips at two ends; a plurality of arched concave holes in match with the necks of the straight-chain starch volumetric flasks are formed in two sides of the clamping strips in the middle; grooves in match with the total width of the plurality of claming strips are formed in the middles of the clamping frames; the heights of the wedged blocks are accordant with the heights of the grooves of the clamping frames; and the holding rack is hollowed and the height of the holding rack is matched with the heights of the straight-chain starch volumetric flasks. When the device is adopted for heating, the straight-chain starch volumetric flasks can be well fixed in water inside a heating container, the uniformity in straight-chain starch heating is improved.
Description
Technical field
The utility model relates to a kind of experimental facilities, relates in particular to a kind of amylose volumetric flask heating servicing unit.
Background technology
When using volumetric flask to heat amylose, usually need that some volumetric flasks are placed in to water and heat simultaneously, in this case, because buoyancy of water volumetric flask is easily punch-drunk, affect the uniformity of amylose heating.The way adopting is now that volumetric flask is fixed with elastic rubber band, but effect is still very poor.
Utility model content
The purpose of this utility model is to provide a kind of amylose volumetric flask heating servicing unit, and fixing amylose volumetric flask while being convenient to heat, improves the uniformity that amylose heats.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
An amylose volumetric flask heating servicing unit, is characterized in that: comprise amylose volumetric flask grip block and for placing the holder of amylose volumetric flask grip block; Described grip block is comprised of some clamping strips, two gripper frames and voussoir, described clamping strip has two kinds, the clamping strip inner side edge that is positioned at two ends is provided with some and arc-shaped notch amylose volumetric flask bottleneck matching, the clamping strip dual-side that is positioned at middle part is provided with some and arc-shaped notch amylose volumetric flask bottleneck matching, in the middle of described gripper frame, be provided with the fluting matching with some clamping strip overall widths, the height of described voussoir is consistent with the height of gripper frame fluting; Described holder hollow and height and amylose volumetric flask matched.
First clamping strip is placed on holder, then the neck of amylose volumetric flask is stuck in the recess between clamping strip one by one, then the clamping strip assembling is put into the fluting of gripper frame, then the fluting that voussoir is also put into gripper frame is fixed, heating preparation accused.During heating, the hand-held gripper frame of operating personnel is put into heating container by grip block, and amylose volumetric flask is well fixed in the water in heating container, has avoided dilapidated, has improved the uniformity of amylose heating.
Further, the clamping strip inner side that is positioned at two ends is provided with some pins or pin-and-hole, and a side that is positioned at the clamping strip at middle part is provided with some pin-and-holes, and opposite side is provided with some pins that mate with pin-and-hole.
Volumetric flask neck is stuck in the recess between clamping strip one by one, and pin-and-hole coordinates with pin, and clamping strip assembling is more firm, prevents that in operating process, clamping strip gets loose and smashes volumetric flask.
Further, described holder one end is provided with baffle plate, and other end opening is convenient to amylose volumetric flask and is vertically passed through.
Baffle plate is used for preventing clamping strip landing from holder, opening be arranged so that the operation that volumetric flask neck is stuck in the recess between clamping strip is one by one more convenient.
The beneficial effects of the utility model are as follows:
During heating, amylose volumetric flask is well fixed in the water in heating container, has avoided east to western askew, has improved the uniformity of amylose heating.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the schematic diagram of disassembling of the utility model clamping strip;
Fig. 3 is the structural representation of the utility model gripper frame;
Fig. 4 is the structural representation of the utility model holder;
Wherein 1 is that gripper frame, 2 is for clamping strip, 3 is for recess, 4 is for holder, 5 is for voussoir, 6 is for pin, 7 is for fluting, 8 is for baffle plate.
The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of amylose volumetric flask heating servicing unit, comprises amylose volumetric flask grip block and for placing the holder 4 of amylose volumetric flask grip block; Described grip block is comprised of three clamping strips 2, two gripper frames 1 and voussoir 5.
As shown in Figure 2, clamping strip has two kinds, the clamping strip inner side edge that is positioned at two ends be provided with three with the arc-shaped notch 3 of amylose volumetric flask bottleneck matching and two pin-and-hole (not shown)s or pin 6, the clamping strip dual-side that is positioned at middle part be provided with three with the arc-shaped notch 3 of amylose volumetric flask bottleneck matching and two pin-and-hole (not shown)s or pin 6.
As shown in Figure 3, in the middle of gripper frame, be provided with the fluting 7 matching with three clamping strip overall widths.
As shown in Figure 4, described holder hollow and height and amylose volumetric flask matched, one end is provided with baffle plate 8, and other end opening is convenient to amylose volumetric flask and is vertically passed through.
First clamping strip is placed on holder by baffle plate one side, then from holder opening one side, the neck of amylose volumetric flask is stuck in the recess between clamping strip one by one, pin coordinates with pin-and-hole makes assembling more firm, then the clamping strip assembling is put into the fluting of gripper frame, the fluting of voussoir also being put into gripper frame is again fixed, and heating preparation accused.During heating, the hand-held gripper frame of operating personnel is put into heating container by grip block, and amylose volumetric flask is well fixed in the water in heating container, has avoided dilapidated, has improved the uniformity of amylose heating.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
