[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Referring to Figures 1-4, this utility model provides a portable glucose electrochemical detection device, including a device body 1, a limiting mechanism 3 is provided inside the device body 1, a stop block 6 is provided on one side of the surface of the device body 1, and a locking mechanism 2 is provided on one side of the stop block 6.

[0025] In use, the locking mechanism 2 works in conjunction with the limiting mechanism 3 to achieve instrument positioning through the meshing transmission between the threads. The return spring then provides sealing protection for the device, making it more convenient and easier to carry.

[0026] The limiting mechanism 3 includes a knob 31 and a drive gear 32. The drive gear 32 is located at the bottom of the knob 31. The drive gear 33 is symmetrically arranged on both sides of the drive gear 32. A rotating rod is provided at the connection of the drive gear 33. An auxiliary gear 34 is provided on the other side of the drive gear 33. A threaded rod 35 is provided at the center of the auxiliary gear 34. A slider 36 is provided on the outside of the threaded rod 35. A sliding groove 37 is provided on the outside of the slider 36.

[0027] The locking mechanism 2 includes a bottom cover 21 and a test port cover plate 22. The test port cover plate 22 is provided on one side of the surface of the bottom cover 21. Limiting rods 23 are symmetrically provided on both sides of the test port cover plate 22. Limiting grooves 24 are provided on the outer side of the limiting rods 23. Locking rods 25 are provided at the bottom of the limiting rods 23. Grooves 26 are provided at the bottom of the locking rods 25. Spring protrusions 27 are provided on one side of the grooves 26. Pull rings are provided on the bottom surface of the spring protrusions 27.

[0028] The main body 1 of the device has symmetrical cover plate grooves 7 on both sides. The inside of the cover plate groove 7 is an auxiliary sliding block. The outside of the auxiliary sliding block is a cover plate 4. The surface of the cover plate 4 is provided with an observation window 5. The inside of the main body 1 of the device is a placement groove 8, and the detector is placed inside the placement groove 8. The display panel of the detector inside the device can be viewed directly through the observation window, so that the instrument reading can be viewed without taking the instrument out of the placement groove 8.

[0029] The stop block 6 is U-shaped, and the shape of the notch in the stop block 6 matches the size of the test port cover plate 22. The limiting groove 24 and the spring protrusion 27 are both located inside the stop block 6. The limiting rod 23, the spring protrusion 27 and the locking rod 25 all pass through the stop block 6. The shape of the spring protrusion 27 matches the shape of the groove 26. A return spring is provided on the opposite surfaces of the limiting rod 23 and the limiting groove 24. The return spring causes the limiting rod 23 to move along the limiting groove 24, thereby pulling the bottom cover 21 closer to the device body 1 for sealing protection.

[0030] The driving gear 32, transmission gear 33 and auxiliary gear 34 are all bevel gears. The connection between the slider 36 and the threaded rod 35 is provided with matching threads. The auxiliary sliding block and the cover plate groove 7 are both dovetail-shaped. The dovetail-shaped protrusions prevent the cover plate 4 from slipping and limit its sliding range.

[0031] Working principle: Before use, move the cover plate 4 along the auxiliary sliding block 7 to open the placement slot 8. Align the test port of the testing instrument with the notch of the stop block 6 and place it into the placement slot 8. Then, rotate the knob 31 to engage the drive gear 32 with the transmission gear 33, which in turn engages the auxiliary gear 34. This causes the threaded rod 35 to rotate in the same direction as the auxiliary gear 34, and simultaneously allows the threaded rod 35 to slide along the sliding groove 37, thus adjusting the size of the testing instrument that the placement slot 8 can accommodate and positioning it to prevent displacement and collision due to shaking during transport. This increases the adaptability of the device. During use, pulling the bottom cover 21 outward causes the test port cover 22 and the limiting rod 23 to move, compressing the reset spring and causing the locking rod 25 to move in the same direction. This allows the spring protrusion 27 to engage with the groove 26 for positioning, facilitating the use of the test port by the tester. After use, the spring protrusion 27 is pulled outward using the pull ring on the bottom surface of the spring protrusion 27, thereby releasing the locking and fixing of the groove 26. The return of the reset spring causes the bottom cover 21 to reset and seal the device, thus achieving comprehensive protection for the device while also facilitating its portability and quick use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
