Abstract

For existing test tube clamp problem such as underaction when using that test tube varies in size, number is different, the utility model provides a kind of student experimenting Combined type test tube clamp and box thereof.Described test tube clamp is made up of handle, clamp, and its structure is: handle front end arranges nut, and the rear end of clamp is provided with stud, and coordinate and be combined into test tube clamp, and the clip quantity of described clamp can be N number of, is connected by crossbeam, wherein, N is natural number, 1≤N≤5.The utility model is easy to operate and reduce use cost.

Description

A kind of student experimenting Combined type test tube clamp and box thereof

Technical field

The utility model relates to the apparatus of the experiments such as Students in Teaching chemistry, biology, specifically, relates to a kind of student experimenting Combined type test tube clamp and box thereof.

Background technology

Test tube clamp is the apparatus of the experiment such as a kind of chemistry, biology, its be mainly used for holding test tubes so as invisible spectro material to be heated, the operation such as colorimetric.

The long handle be now mainly connected together by spring hinge by the structure of test tube clamp and short handle are formed, and the leading inside of described long handle and short handle is equipped with groove, and two grooves form the retaining part of test tube clamp relatively.In the practical application of student experimenting class, now use the deficiency of test tube clamp: 1. the test tube thickness that laboratory uses differs, and as time larger with the most frequently used test tube different diameters, just need to change different test tube clamp, even needs to use iron stand, complex operation.

2. laboratory heating water bath is carried out to the test tube of more than 2 or 2 simultaneously or to its color comparison time, now with test tube clamp can not a folder multiplex.

3. now with the structure of test tube clamp be one, if some positions damage, whole test tube clamp is just scrapped, and use cost is higher.

4. the white liner plate used during the colorimetric of laboratory, generally needing to buy separately, is more often allow student use blank sheet of paper to replace, with after throw away, cause and waste and manufacture rubbish.

Summary of the invention

For existing test tube clamp in use when test tube vary in size, number different time the problem such as underaction, the utility model provides a kind of student experimenting Combined type test tube clamp, not only structural design advantages of simple, and easy to operate, a folder is flexible multi-purpose, reduce the test tube clamp of use cost.

Described student experimenting Combined type test tube clamp, is made up of handle, clamp, and its structure is: handle front end arranges nut, and the rear end of clamp is provided with stud, coordinate and be combined into test tube clamp, and the clip quantity of described clamp can be N number of, is connected by crossbeam, wherein, N is natural number, 1≤N≤5; Described handle is the telescopic handle that can mutually slide that two sections of sockets are formed; Interior interval in described two sections of sockets is inlaid with timer.

One is convenient to place box of the present utility model, is made of plastics, and its structure is: lid and box body fasten, and inside is provided with dividing plate, and inner space and handle, clamp are corresponding; Simultaneously lid is opaque pure white, double white liner plate when doing colorimetric.

The compared with prior art obvious advantage of the utility model:

1. handle described in and clamp are splits, and different according to test tube diameter used during experiment, test tube number difference, selects applicable clamp kind and handle to combine, reach a folder flexible multi-purpose, easy to operate;

2. test tube clamp described in due to one folder flexible multi-purpose, reduce student experimenting room buy different types of test tube clamp, the space of placement of economizing on the use of funds, save.

3. the some positions of test tube clamp described in are damaged, and only need change broken parts, reduce use cost;

4. box described in can arrange number, the size of grid in box as required flexibly, handle and all kinds of clamp is placed in order, and doublely can puts the experimental article such as tweezers, lighter, make student experimenting platform laying for goods neat;

5. described in, the lid of box is set to opaque pure white, the double white liner plate doing colorimetric during experiment;

6. test tube clamp described in is combination, and described clamp kind can select one or more flexible combination to be different suits; Double fastener clamp also can select the different clip of size bore to combine with three folder clamps; The clamp that utilization rate is the highest can configure 2 or multiple in a set of, changes in order to damaging.

Accompanying drawing explanation

Fig. 1 is the utility model handle and single structural representation pressing from both sides clamp and combine; Fig. 2 is the schematic top plan view of the utility model three clamp.Fig. 3 is the front schematic view of the utility model box; Fig. 4 is the top view after the utility model box opens the lid.

Wherein, 1. handle; 2. clamp; 3. nut; 4. stud; 5. crossbeam; 6. clip 1; 7. clip 2; 8 clips 3; 9. box body; 10. lid; 11. dividing plates; 12. timers; 13. sliding extension structures.

Detailed description of the invention

As shown in Figure 1, described student experimenting Combined type test tube clamp, be made up of handle 1, clamp 2, its structure is: handle 1 front end arranges nut 3, and the rear end of clamp 2 is provided with stud 4, coordinates and is combined into test tube clamp.The clip quantity of described clamp 2 can be N number of, is connected by crossbeam 5, and wherein, N is natural number, 1≤N≤5; Described handle 1 is the telescopic structure 13 formula handle that can mutually slide that two sections of sockets are formed; Interior interval in described two sections of sockets is inlaid with timer 12.Detailed description of the invention 1: as shown in Figure 2, clip 1, clip 2, clip 3 are connected by crossbeam 5, form clamp 2, corresponding with handle 1 by the stud of its rear end.

As shown in figs. 34, one is convenient to place box of the present utility model, is made of plastics, its structure is: lid 10 and box body 9 fasten, and inside is provided with dividing plate 11, and inner space and handle 1, clamp 2 are corresponding, simultaneously lid 10 is opaque pure white, double white liner plate when doing colorimetric.

Meanwhile, box can also place other indispensable article of experiment, as tweezers, lighter etc.

The utility model is structural design advantages of simple not only, and can choose suitable clamp as required and combine, easy to operate, a folder is flexible multi-purpose, the test tube clamp that reduces use cost.
