[0003] The existing chromatography test card still has the following problems:

[0004] (1) The shell of the chromatographic test card and the test strip placement slot are usually integrated, which makes it inconvenient to disassemble the test strip placement slot for thorough disinfection and reuse, resulting in a waste of materials.

[0005] (2) The dripping port is exposed to the outside, which makes it difficult to block dust and affects the test results.

[0006] (3) There is no test paper storage box. When using, the test paper needs to be carried extra, which is easy to lose and inconvenient to use. Therefore, it is necessary to propose a detachable chromatography test card. Utility Model Content

[0007] The purpose of the utility model is to provide a detachable chromatography test card, which has the characteristics of being able to separate the shell and the test paper placement slot so as to disinfect the test paper placement slot, conveniently shield the dripping port to prevent dust from entering the dripping port, and conveniently store the test paper, making it easy to carry.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a detachable chromatography test card, comprising a bottom layer, the upper end of the bottom layer being fixedly connected to a support shaft, the outer side wall of the support shaft being sleeved with a middle layer and a top cover in sequence from bottom to top, the left ends of the front ends of the middle layer and the top cover being mounted with a first magnet, the front end of the bottom layer being fixedly connected to a riser, the rear end of the riser being mounted with two second magnets distributed vertically and engaging with the first magnet;

[0009] The upper end of the bottom layer is provided with a test paper placement slot adapted for the test paper;

[0010] A rectangular groove is formed through the front end of the bottom layer, and a drawer is slidably connected to the inside of the rectangular groove.

[0011] In order to facilitate observation of the test status of the test paper, as a preferred detachable chromatography test card of the present invention, the upper end surface of the middle layer is penetrated by a drip groove and an observation port.

[0012] In order to prevent the middle layer and the top cover from being separated from the support shaft, as a preferred embodiment of the detachable chromatography detection card of the present invention, the upper end of the support shaft is threadedly connected to a limit block.

[0013] In order to increase the sealing between the drawer and the rectangular groove, as a preferred embodiment of the detachable chromatography detection card of the present invention, a sealing gasket is fixedly installed on the outer wall of the drawer and is in close contact with the inner wall of the rectangular groove.

[0014] In order to limit the slider inside the limiting groove, as a preferred detachable chromatography detection card of the present invention, the left and right ends of the drawer are fixedly connected with sliders, and the left and right sides of the rectangular groove are provided with limiting grooves respectively connected to the two sliders in a sliding manner.

[0015] In order to keep the test strips inside the drawer dry, as a preferred embodiment of the detachable chromatography test card of the present invention, a breathable net is installed in the middle of the inner wall of the drawer.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] When the test paper placement slot needs to be cleaned, the top cover and the middle layer are pushed and rotated clockwise at the same time to separate the second magnet from the first magnet, thereby exposing the test paper placement slot to the outside and taking out the test paper inside the test paper placement slot, making it convenient for the staff to disinfect and clean the inside of the test paper placement slot so that a new test paper can be placed later.

[0018] When not testing, the first magnet on the middle layer and the outer wall of the top cover is attracted to the matching second magnet, and the drip groove can be shielded through the top cover to prevent dust from entering the drip groove;

[0019] The drawer can be used to store multiple test strips, which is convenient for carrying. The test strips can be easily taken out and placed by sliding the drawer inside the rectangular slot;

[0020] In summary, the shell and the test paper placement slot can be separated to disinfect the test paper placement slot, conveniently cover the dripping port to prevent dust from entering the dripping port, and conveniently store the test paper for easy carrying.
