Abstract

The utility model relates to a laboratory test tube rack, belonging to the laboratory equipment field of general chemistry and physics and including a test tube rack body with the holding hole of the test tube. The technical point is that an elastic locating ring is embedded in the holding hole of the test tube which is one test tube rack body. The inside evenly divided radial direction of the locating ring is provided with more than one group of elastic blocking sheet. After being improved, because the holding hole of the test tube rack is embedded with the elastic locating ring which has the elastic blocking sheet, the aperture of the test tube holding hole on the test tube rack can be enlarged properly. Regardless of whether the aperture is large or small, under the action of the elastic blocking sheet on the elastic locating ring, the test tube can be placed tightly. In this way, the application sphere of the prior test tube rack can be enlarged and the operation is very convenient.

Description

Laboratory's rack for test tube

Technical field

The utility model belongs to general chemistry or physics laboratory's apparatus field, specifically is a kind of laboratory rack for test tube.

Background technology

Rack for test tube is one of must obligato instrument in school or the enterprise's chemical test; conventional rack for test tube only is to be processed with a row or the test tube placed hole more than the row on the test tube support body; the aperture of each placed hole is unified; since in chemical test at different reagent; adopt the caliber specification of test tube also slightly different; like this when test tube is laid; just occur because of caliber easily and lay the aperture not matching; test tube can't normally be placed; the special-purpose rack for test tube that need mate at the test tube of different tube diameters; or the free gap is big after placement; influence normally carrying out of chemical test, therefore, need the rack for test tube of prior art be improved; can being applicable to the different tube diameters test tube, and test tube all can firmly be laid.

The utility model content

The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and the rack for test tube of prior art is improved, and provide a kind of and can be applicable to multiple caliber, and test tube is laid firm laboratory's rack for test tube.

For achieving the above object, the utility model is achieved through the following technical solutions:

Be a kind of laboratory rack for test tube, comprise the test tube support body that is processed with the test tube placed hole, the present technique main points are embedded the shooting property centring ring of the test tube placed hole on the test tube support body, and the inboard Equal round of this centring ring radially is processed with 1 group of above elastic card.

For more firm after test tube is laid, elastic card is made of two groups of upper and lower arrangement successively, and the inner face of elastic card axially is processed with the fastening groove that connects upper/lower terminal successively, and the section of fastening groove is a triangular structure.

In addition, lay easily in order to make test tube, the inner face of elastic card is a circular arc, and each elastic card inner face constitutes circular configuration.

The utility model is after above-mentioned improvement, since in the placed hole of rack for test tube setting-in have an elasticity centring ring of elastic card, therefore the aperture of test tube placed hole on the rack for test tube is suitably strengthened, no matter caliber is big or little, under elastic card effect on the elasticity centring ring, all can normally firmly place, so just enlarge the scope of application of existing rack for test tube, and pick and place conveniently.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1: the utility model example structure schematic diagram.

Fig. 2: elasticity centring ring A is to structural representation among Fig. 1.

Fig. 3: the fastening groove structure schematic diagram of elastic card.

The specific embodiment

As shown in Figure 1, this laboratory rack for test tube, comprise the test tube support body 1 that is processed with test tube placed hole 4, the present technique main points are test tube placed hole 4 embedded the shooting property centring rings 2 on the test tube support body 1, and the inboard Equal round of this centring ring 2 radially is processed with 1 group of above elastic card 3.

When test tube is placed, because elastic card 3 is separate, can be along with the difference in test tube footpath instant variation opening width, each elastic card 3 just along with the placement of test tube tightly the outer wall that blocks test tube all the time, makes rack for test tube be applicable to the test tube of plurality of specifications caliber.

For more firm after test tube is laid, elastic card 3 is made of two groups of upper and lower arrangement successively, and the inner face of elastic card 3 axially is processed with the fastening groove 5 that connects upper/lower terminal as shown in Figure 3 successively, and the section of fastening groove 5 is a triangular structure.

In addition, lay easily in order to make test tube, the inner face of elastic card 3 is a circular arc as shown in Figure 2, and each elastic card inner face constitutes circular configuration jointly.

Occupation mode of the present utility model is same as the prior art, is not described in detail at this.

The utility model is after above-mentioned improvement, since in the placed hole of rack for test tube setting-in have an elasticity centring ring of elastic card, therefore the aperture of test tube placed hole on the rack for test tube is suitably strengthened, no matter caliber is big or little, under elastic card effect on the elasticity centring ring, all can normally place, so just enlarge the scope of application of existing rack for test tube, and pick and place conveniently.

Claims

1. laboratory's rack for test tube comprises the test tube support body that is processed with the test tube placed hole, it is characterized in that embedded the shooting property centring ring of test tube placed hole on the test tube support body, and the inboard Equal round of this centring ring radially is processed with 1 group of above elastic card.

2. laboratory according to claim 1 rack for test tube is characterized in that elastic card is made of two groups of upper and lower arrangement successively.

3. laboratory according to claim 1 and 2 rack for test tube, the inner face that it is characterized in that elastic card is a circular arc, each elastic card inner face constitutes circular configuration.

4. laboratory according to claim 1 rack for test tube is characterized in that the inner face of elastic card axially is processed with the fastening groove that connects upper/lower terminal successively.

5. laboratory according to claim 4 rack for test tube is characterized in that the fastening trench section on the elastic card is a triangular structure.
