Abstract
The utility model relates to a combined test tube clamp which mainly comprises a plurality of test tube clamps, a metal fixing ring and a handle, wherein the test tube clamps are fixed in fixing holes in a rotating manner through threads on the test tube clamps. A pressure plate is extruded, and test tubes are fixed in shrinkage holes on the test tube clamps under the action of elastic force of a spring leaf. The handle is held by the hand, and the metal mixing ring is transferred to the upper part of a water bath pot so as to enable the test tubes to extend into hot water for heating. Then, the metal fixing ring is naturally erected on a pot mouth of the water bath pot without being supported by a laboratory assistant; as the test tubes are stably fixed on the test tube clamps, the test tubes can be prevented from falling. After the heating is completed, the handle is held by the hand, all the test tubes can be taken out once, the efficiency is high, and experimental errors caused by difference in heating time can be reduced or eliminated. The combined test tube clamp has the advantages of simple structure, low cost, strong practicality and easiness in popularization.
Description
Technical field
The utility model relates to and a kind ofly is used for the Combined test-tube folder that a plurality of test tubes heat simultaneously at chemistry and biology laboratory, especially can be used for the water-baths simultaneously of a plurality of test tubes and heat.
Background technology
At present, what chemistry and biology laboratory were used all is very simple single test tube clamp, heats in alcolhol burner or water-bath by hand-held test tube clamp.Often running into a plurality of test tubes in experiment needs the situation of heating simultaneously, can occur the laboratory technician once in a while and be scalded, and test tube falls into water-bath, or test tube take-off time difference causes the situation of experimental error, and each test needs a plurality of test tubes of heating, the number of repetition height, and efficient is low.So have design a kind of safe, efficient, and can heat necessity of the Combined test-tube folder of a plurality of test tubes simultaneously.
Summary of the invention
Heat a plurality of test tubes in order to solve the water-bath simultaneously of existing test tube clamp, can not solve the laboratory technician and be scalded when water-bath is heated, test tube clamp is easily fallen into problems such as water-bath.The utility model provides a kind of Combined test-tube folder, can not only heat a plurality of test tubes simultaneously, and need not the hand-held test tube clamp of laboratory technician when heating, can prevent effectively that test tube from falling into water-bath.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of combined type test tube clamp mainly is made up of several test tube clamps, metal retainer ring and handle.Be threaded on the major axis of test tube clamp, pressing plate links to each other with major axis by shell fragment, and shrinkage hole is positioned at the front end of test tube clamp.Several fixing holes are arranged around the metal retainer ring, and the screw thread of test tube clamp and fixing hole coincide.Handle is connected in metal retainer ring side.
Test tube clamp is by the screw thread on it, and rotation is fixed in the fixing hole.The extruding pressing plate, test tube will be under the effect of shell fragment elastic force, is fixed in the shrinkage hole on the test tube clamp by pressing plate.Hold handle, the metal retainer ring is moved to water-bath top, allow test tube stretch in the hot water and heat.The natural frame of metal retainer ring this moment is on water-bath pot mouth, and the laboratory technician needn't help, because test tube is stably fixed on the test tube clamp, can not drop.Behind to be heated the finishing, hand-held handle can all test tubes of disposable taking-up, and the efficient height reduces or eliminated the experimental error that heat time heating time, difference was brought.
The beneficial effects of the utility model are: utilize the combination of a plurality of test tube clamps, can be disposable carry out the water-bath heating to a plurality of test tubes, need not the hand-held test tube clamp of laboratory technician, reached safety, experiment effect efficiently.
Description of drawings
Below in conjunction with drawings and Examples the design is further specified.
Fig. 1 is a plan structure schematic diagram of the present utility model.
Fig. 2 is a side structure schematic diagram of the present utility model.
Among the figure: 1. metal retainer ring, 2. test tube clamp, 3. shell fragment, 4. pressing plate, 5. shrinkage hole, 6. screw thread, 7. handle, 8. fixing hole.
The specific embodiment
A kind of combined type test tube clamp mainly is made up of several test tube clamps 2, metal retainer ring 1 and handle 7.Test tube clamp 2 is by the screw thread 6 on it, and rotation is fixed in the fixing hole 8.Extruding pressing plate 4, test tube will be under the effect of shell fragment 3 elastic force, is fixed in the shrinkage hole 5 on the test tube clamp 2 by pressing plate 4.Hold handle 7, metal retainer ring 1 is moved to water-bath top, allow test tube stretch in the hot water and heat.Metal retainer ring 1 natural frame is on water-bath pot mouth at this moment, and the laboratory technician needn't help, because test tube is stably fixed on the test tube clamp 2, can not drop.Behind to be heated the finishing, hand-held handle 7 can all test tubes of disposable taking-up, and the efficient height reduces or eliminated the experimental error that heat time heating time, difference was brought.The utility model is simple in structure, cost is low, practical, be easy to promote.
