Description
The technical field is as follows:
the utility model belongs to the detection area, concretely relates to allies oneself with formula and detects test paper card.
Background art:
test paper refers to a paper impregnated with chemicals that can be used to test for the presence of certain substances in liquids or gases by a color change. At present, in order to facilitate detection, a detection test paper is usually prevented from exposing a sample adding hole and an observation hole in a small box, and a test paper card is detected through sample adding of the sample adding hole and observation of the observation hole. However, in actual tests or experiments, different test paper is usually used for detecting one sample, and conventional test paper can only be impregnated one by one, which is very inefficient, and the test is caused by time difference, and the sample changes, which results in inaccurate test result of test paper for later detection. For this patent 201710476192.7 discloses a test strip, realizes the connection of test strip card through first block portion and the mutual interference fit of second block portion to can dip-dye a plurality of test strips once, carry out many times inspection. However, the above connection method is not stable, and the test strip can be clamped into the sample or cannot be clamped with each other due to the small clamping force caused by insufficient manufacturing precision during detection.
The utility model has the following contents:
the utility model discloses a ally oneself with formula and detect test paper card. The utility model discloses simple structure, convenient to use can be fast with the quick fastening connection of more than two detection test paper cards, is difficult for droing, has solved current detection test paper card and has connected not fastening, the problem that drops easily.
In order to achieve the above object, the utility model provides a technical scheme as follows:
a combined test paper card comprises a box body, wherein a pressing frame is fixed in the box body, test paper is fixed between the pressing frame and the top surface of the box body, a test opening is formed in one side of the top of the box body, and an observation opening is formed in the inner side of the test opening in a matched mode; the clamping connecting piece comprises a middle rod body, one end of the middle rod body is connected with a clamping cylinder, the other end of the middle rod body is connected with a vertical rod through a connecting rod, and a clamping block is fixed on the inner side of the vertical rod; the bottom of the clamping cylinder is connected with a push plate through an elastic supporting piece; two L-shaped clamping plates are fixed on the inner side of the top of the clamping cylinder, the two L-shaped clamping plates are arranged symmetrically, and a gap for inserting a vertical rod is formed between the two L-shaped clamping plates.
In a further improvement, the elastic support is a spring.
In a further improvement, the pressing frame is a rectangular pressing frame.
In a further improvement, the box body comprises an upper shell and a lower shell; the pressing frame and the clamping connecting piece are both fixed on the lower shell.
In a further improvement, a threaded column is fixed on the lower shell, and a screw penetrates through the upper shell to be connected with the threaded column so as to fix the lower shell and the upper shell.
Description of the drawings:
fig. 1 is a schematic top view of the present invention;
FIG. 2 is a schematic view of the cross-sectional structure of the A-A plane of the present invention;
fig. 3 is a schematic view of the cross-sectional structure of the plane B-B of the present invention.
The specific implementation mode is as follows:
in order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
Example 1
The combined detection test paper card shown in fig. 1-3 comprises a box body 1, wherein a pressing frame 2 is fixed in the box body 1, detection test paper 3 is fixed between the pressing frame 2 and the top surface of the box body 1, a detection port 4 is formed on one side of the top of the box body 1, an observation port 5 is formed on the inner side of the detection port 4 in a matched manner, and a clamping connecting piece is fixed in the middle of the box body 1; the clamping connecting piece comprises a middle rod body 51, one end of the middle rod body 51 is connected with a clamping cylinder 52, the other end of the middle rod body 51 is connected with a vertical rod 54 through a connecting rod 53, and a clamping block 55 is fixed on the inner side of the vertical rod 54; the bottom of the clamping cylinder 52 is connected with a push plate 57 through an elastic supporting piece 56; two L-shaped clamping plates 58 are fixed on the inner side of the top of the clamping cylinder 52, the two L-shaped clamping plates 58 are symmetrically arranged oppositely, and a gap 59 for inserting the vertical rod 54 is formed between the two L-shaped clamping plates 58.
The resilient support 56 is a spring.
