Description

Technical Field

[0001] This utility model belongs to the field of testing technology and relates to a protective cover for test strips. Background Technology

[0002] Test strip detection is a common biochemical analysis method that involves a chemical reaction between a specific test strip and the analyte, producing a visible color change. It is often used for the rapid detection of the presence or concentration of a target substance. Due to its convenience, speed, and cost-effectiveness, test strip detection is widely used in fields such as medicine, environmental monitoring, and food safety.

[0003] Test strips are typically used to detect gaseous or liquid target substances. The test strips used in the testing process are called test strips. When using test strips to detect gaseous target substances, the test strips are exposed to the environment and are greatly affected by environmental factors. For example, in copper smelting, arsine gas is generated at the work site. Arsine gas has a certain degree of toxicity, and workers working continuously in an environment with arsine gas will have their health affected. To facilitate timely monitoring of the concentration of arsine gas at the work site, test strips are usually used to detect arsine gas. However, if there is electrolyte at the work site, operations such as spraying water are also required. During the testing process, since tests need to be conducted at multiple locations at the work site, splashes of electrolyte or water during the spraying operations may cause electrolyte or water to splash onto the test strips, significantly affecting the test results and causing large errors. This can lead to significant deviations in the judgment and subsequent planning of the workers based on the test results. At the same time, test strips are also prone to damage when placed in an exposed environment, affecting the testing work.

[0004] Therefore, it is necessary to provide a protective cover for the test strip to protect it during the test process, reduce the impact of the external environment on the test results, and reduce the probability of test strip damage. Utility Model Content

[0005] To overcome the problems in the background art, this utility model uses a protective cover to protect the test strip. On the one hand, it can reduce the impact of external substances such as splashed liquids on the accuracy of the test, and on the other hand, it can reduce the probability of test strip damage, which helps the test work to proceed normally.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] The test strip protective cover includes a cover body 1, a push handle 2, a connecting rod 3, a return spring 4, and a test strip clip 5. The push handle 2 is slidably connected to the top plate of the cover body 1 and slides vertically. The connecting rod 3 is located inside the cover body 1, and one end of the connecting rod 3 is fixedly connected to the bottom of the push handle 2, while the other end of the connecting rod 3 is fixedly connected to the test strip clip 5. The return spring 4 is sleeved on the connecting rod 3, with one end of the return spring 4 fixedly connected to the top plate of the cover body 1 and the other end of the return spring 4 fixedly connected to the test strip clip 5. An air vent 6 is opened at the bottom of the side wall of the cover body 1.

[0008] Preferably, a transparent observation window 7 is provided on the side wall of the cover 1.

[0009] Preferably, the cover 1 is composed of a cover 101 and a cylinder 102, wherein the cover 101 and the cylinder 102 cover each other.

[0010] Preferably, the cover 101 is composed of a soft rubber sleeve 1001 and a support frame 1002, with the soft rubber sleeve 1001 covering the outer wall of the support frame 1002.

[0011] Preferably, the cover 101 has a conical structure.

[0012] Preferably, a sealing plug 104 is provided at the bottom of the cover 101, and the cover 101 is sealed to the cylinder 102 through the sealing plug 104 to seal the cover 101 and the cylinder 102 together.

[0013] Preferably, the top plate of the cover 1 is a sealing connector 103, which is slidably connected to the push handle 2.

[0014] Preferably, the test strip protective cover also includes a soft rubber sleeve 8, which is sleeved on the reset spring 4.

[0015] Preferably, a reinforcing hoop 9 is fitted onto the cover 1.

[0016] Preferably, there are several gas inlets 6, which are evenly distributed along the circumferential direction of the side wall of the cover 1.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model provides a passage for the gaseous target substance to flow inside and outside the protective cover by opening a gas vent at the bottom of the side wall of the cover. The target substance can flow from the outside of the protective cover into the inside of the protective cover and come into contact with the test strip to achieve the detection purpose, or it can flow from the inside of the protective cover to the outside, reducing the accumulation of gaseous target substance inside the protective cover and more closely resembling the situation of the test strip being exposed for detection. Thus, while achieving the detection function of the test strip, it also protects the test strip and prevents splashing liquids and other substances from splashing onto the test strip and affecting the test results, thereby making the test results more accurate and providing a more reliable basis for staff to make more accurate judgments.

[0019] 2. This utility model has a simple structure, is easy to carry, and is suitable for use in the workplace. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the contents described herein.

[0026] like Figure 1-4 As shown, the test strip protective cover includes a cover body 1, a push handle 2, a connecting rod 3, a return spring 4, and a test strip clip 5. The push handle 2 is slidably connected to the top plate of the cover body 1 and slides vertically. The connecting rod 3 is located inside the cover body 1, and one end of the connecting rod 3 is fixedly connected to the bottom of the push handle 2, while the other end of the connecting rod 3 is fixedly connected to the test strip clip 5. The return spring 4 is sleeved on the connecting rod 3, with one end of the return spring 4 fixedly connected to the top plate of the cover body 1 and the other end of the return spring 4 fixedly connected to the test strip clip 5. An air vent 6 is opened at the bottom of the side wall of the cover body 1.

[0027] When test strip testing is required, the operator first presses and pushes the sliding handle 2, causing it to slide downwards. This moves the connecting rod 3, which is fixedly connected to it, downwards as well. The connecting rod 3 then moves the test strip clip 5, which is fixedly connected to it, downwards. During this process, the return spring 4 is stretched and extended. As the test strip clip 5 moves downwards, since the bottom of the cover 1 has an open structure, the test strip clip 5 can move through the opening of the cover 1 to the outside of the cover 1. The operator clips the test strip onto the test strip clip 5, releases the sliding handle 2, and after the pressure is released, the return spring 4 shortens, causing the connecting rod 3 and the sliding handle 2 to move upwards. The test strip clip 5 then retracts into the cover 1. The cover 1 is then placed in the predetermined testing position to begin testing. The target substance can enter the cover 1 through the gas vent 6 at the bottom of the cover 1 and come into contact with the test strip. After the testing is completed, the operator removes the test strip from the test strip clip 5 using the aforementioned operation and observes the test results. During the testing process, any splashed liquid will be blocked by the cover 1, thus preventing it from coming into contact with the test strip. The test strip protective cover provides good protection. Furthermore, during the testing process, the test strip is located inside the cover 1 and is unlikely to be damaged by external forces, which facilitates the normal progress of the testing work.

[0028] A transparent observation window 7 is provided on the side wall of the enclosure 1. Staff can observe the color change of the test paper inside the enclosure 1 through the transparent observation window 7, which facilitates the observation of the test results.

[0029] The cover 1 is composed of a cover 101 and a cylinder 102, and the cover 101 and the cylinder 102 cover each other.

[0030] Since the work site environment that requires on-site testing is usually in a complex state, there may be high temperature, corrosion and other conditions. For example, in the copper smelting work site, acidic gases will be generated. High temperature and corrosion will affect the protective cover and cause damage to the protective cover. The cover 1 is designed as a separable structure of cover 101 and cylinder 102 to facilitate the replacement or repair of damaged parts.

[0031] The cover 101 is composed of a soft rubber sleeve 1001 and a support frame 1002, with the soft rubber sleeve 1001 covering the outer wall of the support frame 1002.

[0032] The soft rubber sleeve 1001 can provide a certain degree of protection for the support frame 1002, reducing the impact of complex environments such as high external temperatures or corrosive gases on the support frame 1002, and reducing the probability of damage (deformation, corrosion, etc.) to the support frame 1002.

[0033] The cover 101 has a conical structure.

[0034] A sealing plug 104 is provided at the bottom of the cover 101, and the cover 101 is sealed to the cylinder 102 through the sealing plug 104 to seal the cover 101 and the cylinder 102.

[0035] By using the sealing plug 104, the sealing effect after the cover 101 and the cylinder 102 are closed can be enhanced. Thus, when liquid splashes onto the outer wall of the cover 101 or the cylinder 102, the liquid is less likely to flow into the cover 1 from the connection gap between the cover 101 and the cylinder 102, thereby enhancing the protective function of the cover 1.

[0036] The top plate of the cover 1 is a sealing connector 103, which is slidably connected to the push handle 2.

[0037] When the top plate of the cover 1 is a sealing connector 103, the sealing connector 103 can be detachably connected to the side wall of the cover 1, which facilitates the replacement or maintenance of the components.

[0038] The test strip protective cover also includes a soft rubber sleeve 8, which is sleeved on the reset spring 4.

[0039] The soft rubber sleeve 8 provides a certain degree of protection for the return spring 4, reducing the probability of the return spring 4 being damaged by high temperature, corrosion, etc.

[0040] A reinforcing hoop 9 is fitted onto the cover 1. The environment in which the cover 1 is used is also relatively complex, and it is easily damaged by corrosion and other factors, resulting in cracks and other damage. The reinforcing hoop 9 can, to a certain extent, allow the cover 1 to maintain its original shape after deformation or cracking, reducing the probability of the defect continuing to expand and reducing the possibility of the cover 1 suffering significant damage during use, which could lead to interruption of testing.

[0041] The gas inlets 6 are numerous and evenly distributed along the circumference of the side wall of the cover 1. This increases the channels for gas flow between the inside and outside of the cover 1, making the test strip detection process closer to the exposed testing situation and reducing the impact of the cover 1 on the test strip detection.

[0042] The working process of this utility model is as follows: When it is necessary to use test strips to detect gaseous target substances at the work site, the staff first presses and pushes the sliding handle to push the test strip clip out of the cover, then clips the test strip onto the test strip clip. After that, the sliding handle is released, and the test strip clip holding the test strip retracts into the cover under the action of the return spring. Then the test strip protective cover is placed at the predetermined detection position, and the detection work begins. The staff can observe the detection status of the test strip inside the cover through the transparent observation window, or they can take the test strip out of the cover to observe the detection status.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
