Abstract

A complex test tube clamp is disclosed by the utility model and belongs to a test tool, which comprises a clamp body with a handle and a spring on the clamp body and additional two identical symmetrical lined clamps. On opposite sides of the two lined clamps, more than two clamping gaps that are arranged parallel with each other lengthways. By using such a utility model, two or more test tubes can be clamped, the utility model is usable and efficient, and is in particular applicable for contrast tests.

Description

Compound test tube clamp

Technical field

The utility model relates to a kind of test tools made, is specifically related to a kind of test tube clamp.

Background technology

Test tube clamp is laboratory, analysis room a kind of test tools made very commonly used of universities an middle schools' physics, chemistry, biology laboratory and industrial or agricultural scientific research department.When doing contrast test, need use simultaneously with the test tube clamp more than two or two usually, but common test tube clamp generally can only press from both sides a test tube, such test tube clamp is just very inconvenient, but also influences experiment effect.

The utility model content

The purpose of this utility model is: a kind of compound test tube clamp that can press from both sides two or two above test tubes simultaneously is provided.

The technical solution of the utility model is: a kind of compound test tube clamp, comprise the clamp of being with handle and the spring on the clamp, it is characterized in that: also have two identical symmetries to be installed in row folding on the clamp, two row foldings are the side folder mouth that has two above parallel longitudinals to arrange in opposite directions.

In the described row folding one is fixedlyed connected with clamp, and another piece is connected with clamp by bearing pin and can rotates around this bearing pin.So that many test tubes are clamped and guarantee test tube is stressed evenly.

The cross section of described folder mouth is an arc.Be convenient to clamp test tube.

The shape size of each the folder mouth on the described row folding is all identical.

Have at least a shape to vary in size in the folder mouth on the described row folding with other.

It is to be noted: the folder mouth size on the row folding can be made different or identical as required.

The beneficial effects of the utility model are: because the folder mouth on the row folding is more than two, can press from both sides two or two above test tubes simultaneously, and easy to use, high efficiency.

Below in conjunction with the drawings and specific embodiments the utility model is further specified.

The specific embodiment

Embodiment 1

As shown in Figure 1 to Figure 3, a kind of compound test tube clamp, comprise the clamp 1 of being with handle, spring 2 is arranged on the clamp 1, also have two identical and symmetrical row foldings 5 that are installed on the clamp 1, two row foldings 5 are the side folder mouth 3 that has three parallel longitudinals to arrange in opposite directions, the cross section of folder mouth 3 is an arc, the shape size of each folder mouth is all identical, in the row folding 5 one is fixedlyed connected with clamp 1, another piece is connected with clamp 1 by bearing pin 4 and can rotates around this bearing pin, so that many test tubes are clamped and guarantee that test tube is stressed evenly.

This compound test tube accompanies following several usage:

First kind is test tube of folder on this compound test tube clamp, and its using method is identical with common test tube clamp.

Second kind is to press from both sides two test tubes on this compound test tube clamp simultaneously, two identical test tubes of diameter is placed on two folder mouths of test tube clamp, and the handle of holding test tube clamp can use; Can also be with two diameter differences but the little test tube of diameter difference be placed on two folders mouthful of test tube clamp, when test tube clamp stepped up test tube, the handle of holding test tube clamp can use; When only pressing from both sides two test tubes, preferably two test tubes are placed on two folders on the two ends of test tube clamp and mouthful go up and to use, with guarantee two test tubes stressed evenly.

The third is to press from both sides three test tubes on this compound test tube clamp simultaneously, three identical test tubes of diameter is placed on three folder mouths of test tube clamp, and the handle of holding test tube clamp can use; Can also three the different but test tube that the diameter difference is little of diameter be placed on three folders mouthful of test tube clamp, when test tube clamp stepped up test tube, the handle of holding test tube clamp can use.

Embodiment 2

Extremely shown in Figure 6 as Fig. 4, a kind of compound test tube clamp, comprise the clamp 1 of being with handle and the spring 2 on the clamp 1, also have two identical and symmetrical row foldings 6 that are installed on the clamp 1, two row foldings 6 are the side folder mouth 3 that has two parallel longitudinals to arrange in opposite directions, and the cross section of folder mouthfuls 3 is an arc, but the shapes of two folders mouthful vary in size, in the row folding 6 one is fixedlyed connected with clamp 1, and another piece is connected with clamp 1 by bearing pin 4 and can rotates around this bearing pin.

This compound test tube accompanies following several usage:

Second kind is to press from both sides two test tubes on this compound test tube clamp simultaneously, and two diameters and the folder mouthful test tube that size is complementary are placed on corresponding two folder mouths of test tube clamp, and the handle of holding test tube clamp can use.
