Description

Technical Field

[0001] The utility model relates to the field of test assistance, in particular to a dry chemical test card device with a retreat strip and a light reflection method. Background Art

[0002] At present, many samples often need to use a clamping device to clamp the test paper when using the photochemical reflectance method for detection. The commonly used device for clamping the test paper is the clamping device shown in the patent announcement document CN215263341U to clamp the test paper. However, there is a problem in the use of this clamping device, that is, the clamping device of this structure pops off the test paper after use, and needs to be pulled out manually or with the help of tools. Utility Model Content

[0003] In view of the above problems, the utility model proposes a light reflection method dry chemical test card device with a withdrawal strip, which can be used to clamp a test paper with relatively large hardness, and after the test is completed, there is no need to manually remove the test paper or use a contact tool.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A dry chemical test card device with a light reflection method with a retreat strip comprises a first plate body, a spring and a slider, wherein a bearing plane is arranged on the first plate body, the slider is slidably arranged on the first plate body, one end of the spring abuts against the slider, and the other end of the spring abuts against the first plate body, a clamping protrusion is arranged on the first plate body, and there are two clamping protrusions, the two clamping protrusions are distributed in an eight-shaped shape, the bearing plane is located in front of the two clamping protrusions, a detection through hole is opened on the first plate body, a dustproof plate is arranged on the first plate body, the dustproof plate is closely attached to the opening of the detection through hole, and the dustproof plate is partially transparent or completely transparent.

[0006] The method of using this testing device is as follows: first, place the hard test strip to be tested on the load-bearing plane, and make the test strip card stuck between the two clamping protrusions. The part of the dustproof plate located at the opening of the detection through hole must be transparent (so the dustproof plate can be completely transparent or partially transparent), so that it is convenient to optically detect the test strip through the detection through hole. After the detection is completed, the slider can be pushed, and the slider slides toward the test strip and contacts the test strip. The test strip slides out from between the two clamping protrusions and detaches from the load-bearing plane under the pushing action of the slider. The operation is convenient and quick. When the test strip slips off the load-bearing plane, stop pushing the slider, and the slider will return to its original position under the action of the spring.

[0007] In summary, the device can make the test strip clamped between the two clamping protrusions slide out by pushing the slider, and is easy to use and operate.

[0008] Specifically, in this device, the two clamping protrusions are distributed in an eight-shaped shape, so as to better clamp the test strip.

[0009] At the same time, in this device, the dustproof plate can be fixed on the first plate body by gluing, and the bearing plane and the dustproof plate are respectively located on both sides of the first plate body.

[0010] Optionally, a plate sleeve column is provided on the first plate body, a block sleeve column is provided on the sliding block, and both ends of the spring are respectively sleeved and matched with the plate sleeve column and the block sleeve column.

[0011] The two ends of the spring are respectively sleeved and matched with the plate sleeve column and the block sleeve column to improve the installation stability of the spring.

[0012] Optionally, there are two springs, and the two springs are in a parallel and non-contact state.

[0013] Optionally, a guide opening is provided on the first plate body, and a guide block is provided on the sliding block, and the guide block is slidably matched with the guide opening.

[0014] The guide block and the guide opening sliding fit together can ensure that the slider slides more stably on the first plate and avoid the slider from being offset during the sliding process. Specifically, the two springs are located on both sides of the guide block, which can ensure that the extrusion force borne by the two springs during the movement of the slider is roughly the same.

[0015] Optionally, a contact portion is provided on the plate body, and the contact portion is an L-shaped contact portion, and the contact portion is used to contact the spring.

[0016] The abutting portion has two sections that contact the corresponding spring, which facilitates the spring to be biased when the spring is assembled to the plate body.

[0017] Optionally, an anti-deflection blocking portion is provided on the first plate body, and there are two anti-deflection blocking portions. The bearing plane is located between the two anti-deflection blocking portions, and the two anti-deflection blocking portions are on a straight line.

[0018] The function of the two anti-deflection blocking parts is to limit the test strip located on the load-bearing plane. Therefore, when the test strip is placed on the load-bearing plane, one end of the test strip is clamped by the two clamping protrusions, and the other end of the test strip is limited by the two anti-deflection blocking parts, thereby ensuring that the test strip is stably placed on the load-bearing plane.

[0019] Optionally, it also includes a second plate body, which is plugged into the first plate body, the dustproof plate is located between the first plate body and the second plate body, and the second plate body is provided with a light-transmitting hole, and the light-transmitting hole and the detection through hole are respectively located on both sides of the dustproof plate.

[0020] The function of the light-transmitting hole is to transmit light, and the function of the second plate body is to be connected with other equipment. At the same time, the second plate body can protect the dustproof plate.

[0021] Optionally, a receiving groove is provided on the second plate body, and the dustproof plate is located in the receiving groove.

[0022] Specifically, the dustproof plate is completely inserted into the receiving groove, and the light transmission hole is also located at the receiving groove.

[0023] The utility model has the beneficial effect that the test paper strip clamped between the two clamping protrusions can be made to slide off by pushing the slider, and the use and operation are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As attached Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, a dry chemical test card device with a light reflection method with a retreat strip includes a first plate body 2, a spring 3 and a slider 1. A bearing plane 203 is provided on the first plate body 2. The slider 1 is slidably arranged on the first plate body 2. One end of the spring 3 abuts against the slider 1, and the other end of the spring 3 abuts against the first plate body 2. A clamping protrusion 202 is provided on the first plate body 2, and there are two clamping protrusions 202. The two clamping protrusions 202 are distributed in an eight-shaped shape. The bearing plane 203 is located before the two clamping protrusions 202. A detection through hole 205 is opened on the first plate body 2. A dustproof plate 4 is provided on the first plate body 2. The dustproof plate 4 is close to the opening of the detection through hole 205, and the dustproof plate 4 is partially transparent or completely transparent.

[0030] The method of using this testing device is as follows: first, place the hard test strip to be tested on the bearing plane 203, and make the test strip card clamped between the two clamping protrusions 202. The part of the dustproof plate 4 located at the opening of the detection through hole 205 must be transparent (so the dustproof plate 4 can be completely transparent or partially transparent), so that it is convenient to optically detect the test strip through the detection through hole 205. After the detection is completed, the slider 1 can be pushed, and the slider 1 slides toward the test strip and contacts the test strip. Under the pushing action of the slider 1, the test strip slides out from between the two clamping protrusions 202 and detaches from the bearing plane 203. The operation is convenient and quick. After the test strip slips off the bearing plane 203, stop pushing the slider 1, and the slider 1 will return to its original position under the action of the spring 3.

[0031] In summary, the device can make the test strip clamped between the two clamping protrusions 202 slide out by pushing the slider 1, and is easy to use and operate.

[0032] Specifically, the two clamping protrusions 202 in this device are distributed in an eight-shaped shape, so as to better clamp the test strip. At the same time, it should be noted that this device is not suitable for clamping soft test strips.

[0038] The guide block 101 and the guide opening 201 slide together to ensure that the slider 1 slides more stably on the first plate 2 and avoids the slider 1 from being offset during the sliding process. Specifically, the two springs 3 are respectively located on both sides of the guide block 101, so that the extrusion force borne by the two springs 3 during the movement of the slider 1 is roughly the same.

[0042] The function of the two anti-deflection blocks 204 is to limit the test strip located on the load-bearing plane 203. Therefore, when the test strip is placed on the load-bearing plane 203, one end of the test strip is clamped by the two clamping protrusions 202, and the other end of the test strip is limited by the two anti-deflection blocks 204, thereby ensuring that the test strip is stably placed on the load-bearing plane 203.
