Description

Technical Field

[0001] This utility model relates to the field of test reagent card technology, specifically to an auxiliary opening mechanism for test reagent card cases. Background Technology

[0002] Test strips are portable testing tools used for the rapid detection of specific target substances in biological samples. They are widely used in medical diagnostics, food safety, environmental monitoring, and other fields. Their core features are ease of operation, rapid results, and no need for complex instruments, making them suitable for on-site, real-time testing. Test strips mainly consist of an upper cover and a lower casing. Due to errors in transportation, storage, and processing, the test strips may become misaligned within the casing. In such cases, the casing needs to be reopened using an opening mechanism to readjust the test strips.

[0003] Currently, there is a lack of rapid shell-opening mechanisms in the use of shell-opening devices. Most of them are operated manually, that is, by inserting fingernails or tweezers into the opening and closing gap of the shell and prying it open. However, uneven force applied manually can easily cause the shell to crack or deform. Tweezers and other tools can easily scratch the test strip, causing contamination or damage. Moreover, the operation efficiency is low, especially when processing in batches, which is time-consuming and labor-intensive. Therefore, an auxiliary shell-opening mechanism for test reagent shells is proposed to add a rapid shell-opening mechanism. It uses sliding, guiding, and supporting methods to quickly complete the shell-opening action, improve the convenience and flexibility of the shell-opening operation, and thus improve the use effect.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To facilitate quick opening of the casing using sliding, guiding, and supporting methods, thereby improving usability, such as... Figure 1-3 As shown, the present invention provides an auxiliary shell-opening mechanism for testing reagent cartridges, comprising a base 1, a shell-opening assembly 3, and an adjustment assembly 4. A support platform 2 is bolted to the top of the base 1, and the shell-opening assembly 3 is slidably connected to the top of the support platform 2. The adjustment assembly 4 is located on the back of the shell-opening assembly 3 at the top of the support platform 2.

[0024] The shell opening assembly 3 includes a sliding frame 301, a support frame 302 is provided on one side of the sliding frame 301, a pin 303 is bolted to one side of the sliding frame 301, and a clamping plate 304 is bolted to one side of the sliding frame 301 located on the side of the pin 303.

[0025] In use, a quick shell-opening mechanism is added through the sliding frame 301, support frame 302, ejector pin 303 and card plate 304. By using sliding, guiding and supporting methods, the test reagent card is opened and widened in sequence, which improves the continuity and convenience of the shell-opening operation.

[0026] The 304 stainless steel plate has a triangular cross-section.

[0027] To improve the safety of adjustment operations, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes the following: the adjustment component 4 includes a fixed frame 401, a mounting frame 402 is slidably connected to the top of the fixed frame 401, a slide block 403 is slidably connected to the bottom of the mounting frame 402, an adjustment bracket 404 is mounted on the bottom of the slide block 403 via a bearing, a miniature vacuum pump 5 is bolted to the back of the fixed frame 401, and the air inlet of the miniature vacuum pump 5 is connected to the adjustment bracket 404 via a hose.

[0028] In use, an auxiliary adjustment mechanism is added through the fixing frame 401, mounting frame 402, slide 403, adjusting bracket 404, and micro vacuum pump 5. The position of the test strip is adjusted by means of vacuum negative pressure, rotation, and sliding.

[0029] For example, such as Figure 2 As shown, the present invention also includes a spring 305 installed between the sliding frame 301 and the support frame 302 via a spring seat, a limiting plate 306 connected to one side of the top of the support frame 302 via bolts, a ball bearing 307 being rolledly connected to the bottom of the limiting plate 306 and the surface of the support frame 302 via a reserved ball groove, and an opening 308 corresponding to the ejector pin 303 and the clamping plate 304 being provided inside the support frame 302.

[0030] In use, the spring 305, the limiting plate 306, the ball 307 and the opening 308 facilitate the opening and widening action of the ejector pin 303 and the clamping plate 304 to quickly open the shell.

[0031] For example, such as Figure 4 As shown, the present invention also includes a perforated plate 405 bolted to the bottom of the adjusting bracket 404, a stepper motor 406 bolted to the slide block 403, and the stepper motor 406 connected to the adjusting bracket 404 via a drive shaft. The bottom of the mounting bracket 402 is provided with a slide rail 407, and the slide block 403 is slidably connected to the slide rail 407 via a top slider.

[0032] In use, the test strip position can be easily controlled and adjusted by the perforated plate 405, stepper motor 406, and slide rail 407. Both sides of the mounting bracket 402 are equipped with slide rods through reserved openings, and one end of the slide rod passes through the slide rail 407 and is fixedly connected to the top slider of the slide block 403.

[0033] For example, such as Figure 3As shown, this utility model also includes a double threaded rod 201 installed in the support platform 2 via a bearing, a threaded seat 202 sleeved around the double threaded rod 201, and the threaded seat 202 connected to the sliding frame 301 by bolts. A limit groove 203 is opened at the top of the support platform 2, and the sliding frame 301 is slidably connected to the limit groove 203 via a bottom slider. A rotating rod 6 is connected to one side of the support platform 2 by bolts, and one end of the rotating rod 6 is connected to the double threaded rod 201 by bolts.

[0034] In use, the position and spacing of the shell opening assembly 3 can be adjusted by means of the double threaded rod 201, threaded seat 202, limiting groove 203, and rotating rod 6. The double threaded rod 201 includes a telescopic protective cover, and the operator can apply grease to the surface of the double threaded rod 201 for regular maintenance.

[0035] For example, such as Figure 4 As shown, the present invention also includes an electric push rod 7 bolted to the top of the fixing frame 401, and the output end of the electric push rod 7 bolted to the mounting frame 402.

[0036] In use, the electric push rod 7 facilitates the lifting and lowering of the mounting bracket 402 to assist in adjusting the test strip. The base 1 includes a controller, and the electric push rod 7 is electrically connected to the controller via a wire.

[0037] When using this utility model, the operator first places one end of the test reagent card on the support frame 302, rotates the rotating rod 6 to drive the double threaded rod 201 to rotate, and the threaded seat 202 drives the sliding frame 301 to slide towards the middle. Under the pushing force of the spring 305, the support frame 302 gradually clamps the test reagent card. At the same time, the sliding frame 301 pushes the ejector pin 303 through the opening 308 and inserts it between the upper and lower shells of the test reagent card, so that a gap appears in the test reagent card. Then, the operator manually pushes the test reagent card to the side of the fixed frame 401 so that the card plate 304 can be inserted into the gap. During the sliding process, the card plate 304, which gradually increases in thickness, can widen the gap and play an auxiliary role in widening the opening until the upper and lower shells are finally separated.

[0038] When the operator adjusts the position of the test strip inside the casing, the electric push rod 7 can be activated in advance to drive the mounting bracket 402 to slide down to the top of the test strip. The negative pressure generated by the micro vacuum pump 5 will cause the orifice plate 405 to lift the test strip. According to the actual placement position of the test strip inside the casing, the operator can activate the stepper motor 406 to drive the adjustment bracket 404 and the test strip to rotate, and then push the slide rod to drive the slide base 403 to slide and adjust the placement position of the test strip. This can replace the traditional manual contact adjustment method, avoid contaminating the test strip and affecting the actual use effect and quality, and make it more convenient and stable to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
