Abstract
The utility model relates to a chemical test table for middle schools, which belongs to the common equipment of chemical laboratories. The chemical test table comprises a reagent box body, wherein the top of the box body is processed with a reagent tube orifice. The utility model is characterized in that the middle section of the reagent box body is an opening structure, and an elastic tightening ring is arranged in the reagent tube orifice. The utility model satisfies the requirement for positioning a chemical experimental test tube for a student. The utility model has the advantages of simple structure, easy manufacture, strong adaptability of the specification of test tubes and firm test tube positioning.
Description
Technical field
The utility model belongs to general chemical laboratory equipment, specifically is a kind of middle school chemistry test operation platform.
Background technology
Chemical test is in the chemo study in middle school requisite one minute, chemical test generally all is to carry out under teacher's leading, but, because operating desk is hard material processing, add that operating desk that various test tubes use is subjected to the influence of factors such as machining accuracy and standard, test tube free gap in the test tube hole is bigger, easily because reasons such as collision are damaged test tube, particularly test tube is caused danger injury student's health easily when using the stronger reagent of corrosivity, therefore, just needs design a kind of good stability, and can adapt to the test operation platform that the plurality of specifications test tube is used, to satisfy modern student's learning demand.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of simple in structure, is easy to processing, and strong to test tube specification adaptability, test tube is laid firm middle school chemistry test operation platform.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of middle school chemistry test operation platform, comprise that the top is processed with the reagent box body of reagent pore, the stage casing that it is characterized in that the reagent box body is a hatch frame, and the elasticity tight loop is set in the reagent pore.
For the ease of chucking reagent box body, its outer end of vertical section of elasticity tight loop is the hierarchic structure of symmetry.
In addition, in order to satisfy the caliber requirement of plurality of specifications test tube, the upper/lower terminal of vertical its inner chamber of section of elasticity tight loop is processed the bail wire that inside spy is stretched respectively, and the center of bail wire is the reagent pore.
The requirement that student's chemical test test tube is laid has been satisfied in application of the present utility model, have simple in structure, be easy to processing, strong to test tube specification adaptability, test tube is laid firm advantage.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model structural representation.
Fig. 2: the cross-sectional view of elasticity tight loop.
The specific embodiment
As shown in Figure 1, this middle school chemistry test operation platform, comprise that the top is processed with the reagent box body 1 of reagent pore 2, improvement of the present utility model is that the stage casing of reagent box body 1 is a hatch frame 4, elasticity tight loop 3 is set in the reagent pore 2, the stage casing of reagent box body 1 is that hatch frame 4 is convenient to clean the dust in the reagent box body 1, and elasticity tight loop 3 is convenient to tighten the reagent pipe.Occupation mode of the present utility model is same as the prior art.
In addition, in order to be convenient to tighten the reagent box body, its outer end of vertical section of elasticity tight loop 3 is the hierarchic structure 6 of symmetry as shown in Figure 2, and for ease of clamping the position processing ramp 7 that links of steps at different levels.
In addition, in order to satisfy the caliber requirement of plurality of specifications test tube, the upper/lower terminal of vertical its inner chamber of section of elasticity tight loop 3 is processed the bail wire 5 that inside spy is stretched respectively, and the center of bail wire 5 is a reagent pore 2.
The requirement that student's chemical test tube is laid has been satisfied in application of the present utility model, have simple in structure, Be easy to processing, to test tube specification strong adaptability, test tube is laid firmly advantage.
Claims (3)
1, a kind of middle school chemistry test operation platform comprises that the top is processed with the reagent box body of reagent pore, and the stage casing that it is characterized in that the reagent box body is a hatch frame, and the elasticity tight loop is set in the reagent pore.
2, middle school chemistry test operation platform according to claim 1 is characterized in that the hierarchic structure of its outer end of vertical section of elasticity tight loop for symmetry.
3, middle school chemistry test operation platform according to claim 1 and 2 is characterized in that the upper/lower terminal of vertical its inner chamber of section of elasticity tight loop is processed the bail wire that inside spy is stretched respectively, and the center of bail wire is the reagent pore.
