[0002] POCT testing instruments are widely favored because of their advantages such as miniaturized experimental instruments, simple operation, and instant reporting of results, which eliminate the complicated processing procedures of specimens in laboratory tests.

[0003] A large number of reagent cards are required during the instant testing process. After the reagent card is inserted into the POCT testing instrument, the instrument will use a power device to drive the belt to move the reagent card into place for testing and automatically discard the card after the test. The installation and service life of the belt determine the accuracy and service life of the instrument's detection.

[0004] The conventional installation of the belt is to first put it into the driven wheel at one end, and then pull the belt hard to put it into the driven wheel at the other end. The action of external force will cause the belt to loosen and shake, affecting its service life. Since each person's operating strength and habits are different, the deformation of the belt cannot be unified due to each person's strength, causing the path set by the instrument to shift, affecting the product performance such as the reagent card injection detection and card ejection, and affecting the consistency of product performance.

When the second limiting component 3 contacts the first mounting portion 521 of the driven wheel accessory 5, the first limiting component 2 and the second limiting component 3 limit and fix the driven wheel accessory 5 to be installed in the horizontal direction.

[0032] In order to better limit the position of the driven wheel accessory 5, the base plate 1 also includes a limiting groove 11. In the thickness direction of the base plate 1, the limiting groove 11 is recessed in the upper surface of the base plate 1, but does not break through the lower surface of the base plate 1. The limiting groove 11 can carry and limit the driven wheel accessory 5. The limiting groove 11 is adapted to the mounting base 51. Preferably, the limiting groove 11 is adapted to the bottom surface shape of the mounting base 51, so that the bottom wall and the side wall of the limiting groove 11 are in contact with the mounting base 51 to limit the mounting base 51.

The length of the track 314 is the displacement of the sliding component 32.

[0043] The sliding component 32 includes a second main body 321 and a first avoidance portion 322 . The first avoidance portion 322 protrudes from the second main body 321 toward the first limiter 21 . The distance between the top wall of the second main body 321 and the substrate 1 is greater than the distance between the top wall of the first avoidance portion 322 and the substrate 1 .

[0044] The sliding component 32 includes a first side portion 323 and a second side portion 324, the first side portion 323 protrudes from the side wall of the second main body portion 321 facing the first limit member 21, and the first side portion 323 is opposite to the first limit member 21, and the second side portion 324 protrudes from the side wall of the second main body portion 321 facing the first limit member 21, and the first side portion 323 is opposite to the second side portion 324.

In the thickness direction of the first avoidance portion 322, two or more first avoidance holes 325 penetrate the first avoidance portion 322, or one first avoidance hole 325 penetrates the first avoidance portion 322, and the other first avoidance hole 325 penetrates part of the first avoidance portion 322 and part of the first side portion 323. Penetration refers to forming a through hole on an object.

[0047] The bottom surface of the sliding component 32 also includes a sliding seat 326. The second main body 321 and the sliding seat 326 can be fixedly connected or connected by existing technologies such as screws and nuts. The sliding seat 326 includes an inverted U-shaped sliding frame 3261 and a side claw 3262 extending from the edge of the sliding frame 3261 toward the first bending portion 312. The side claw 3262 extends into the space enclosed by the first bending portion 312, the second bending portion 322 and the base 311, so that the sliding component 32 is not easy to separate from the guide rail 31. During assembly, the sliding component 32 moves toward the first limiting member 21, and the first mounting portion 521 is clamped between the first side portion 323, the second side portion 324, the first avoidance portion 322 and the first main body portion 214 and the first protruding portion 215. The second mounting portion 522 is located between the sliding component 32 and the mounting base 51.

Specifically, the wall portion of the second side portion 324 facing the first side portion 323 is an arc-shaped wall portion. When the position of the connecting member 52 is slightly offset and the sliding member 32 moves toward the first limiting member 21, the end 3241 of the arcuate wall portion A of the second side portion 324 will contact the wall of the first mounting portion 521 and shift the wall of the first mounting portion 521 in the direction toward the first side portion 323, and the end 3242 of the arcuate wall portion B will abut the first mounting portion 521 against the fixed mounting position, that is, the end 3242 of the arcuate wall portion B contacts the wall of the first mounting portion 521; when the connecting member 52 is accurately placed and the sliding member 32 moves toward the first limiting member 21, the end 3242 of the arcuate wall portion B of the second side portion 324 will abut against the wall of the first mounting portion 521 to limit the first mounting portion 521.

[0048] The movement of the sliding component 32 can be operated by the push-pull quick clamp 6. One end of the push-pull quick clamp 6 is connected to one end of the second main body 321. Specifically, the connecting rod 61 is connected to the second main body 321. The push-pull handle 62 is operated upward or downward to move the second main body 321 connected to the connecting rod 61, so that the sliding component 32 can make reciprocating linear motion on the guide rail 31. It is defined that when the push-pull handle 62 is upward, the sliding component 32 moves to the end of the guide rail 31, and the second limit assembly moves to the position of fixing the driven wheel accessory 5. When the push-pull handle 62 is downward, the sliding component 32 moves to the initial end of the guide rail 31, and the second limit assembly moves to a position away from the driven wheel accessory 5.

[0049] A horizontal quick clamp 7 can also be provided on the base plate 1. By lifting or pressing the handle 71 upward or downward, the positioning ring 72 and the driven wheel accessory 5 can be loosened and squeezed to assist in positioning the mounting base 51. The number of horizontal quick clamps 7 is 1 or more, and the mounting base 51 can be positioned from all directions.

[0050] Steps for assembling the driven wheel accessory 5:

[0051] ① The mounting base 51 is placed into the limiting groove 11 and is clamped into the first wall portion 211 of the first limiting assembly 2;

[0052] ② Press the handle 71 downward to squeeze the positioning ring 72 of the horizontal quick clamp 7 onto the mounting base 51;

[0053] ③ First, assemble the belt to the driven wheel 53 fixedly connected to the mounting base 51, then insert the driven wheel 53 connected to the connecting member 52 into the belt at the other end, and move the connecting member 52 so that its second mounting hole 55 is aligned with the base clearance hole 13;

[0054] ④ By pressing down the push-pull handle 62, the sliding component 32 of the second limit assembly 3 moves to the end, against the first mounting portion 521, and then tighten the screw from the second mounting hole 55 of the second mounting portion 522.

[0055] By fixing and limiting the driven wheel accessory 5 with the auxiliary belt assembly tooling, the belt is installed on the driven wheel 53, and the connecting member 52 is installed on the mounting base 51, and the deformation of the belt is certain; the assembly position of the connecting member 52 is fixed, which reduces the impact on the belt during the assembly of the driven wheel accessory 5, increases the service life of the belt, and improves the performance consistency.
