Inspection test piece device

Abstract

A test piece device includes a pivot unit and a locking unit installed between a base unit and a top cover unit. The top cover unit is rotatable relative to the base unit through the pivot unit, the base unit includes a base and a first inspection part arranged on the base, the top cover unit includes a cover and The perforation and the first observation window are arranged on the cover body, the locking unit includes a clip seat, a movable seat and a fixed seat, the clip seat is arranged on the cover body and is located on both sides of the perforation hole, the The movable seat has a clamped block sandwiched by the clamping seat, a locking block disposed on the clamped block and an operating block located in the through hole, the fixed seat is disposed on the seat body and With lock slot. When the top cover unit is in the closed position, the locking block can be inserted into the locking slot to lock the top cover unit and the base unit to each other. In this way, the present invention can reduce the chance of sample contamination and improve test accuracy.

Description

technical field [0001] The invention relates to a device for inspecting a sample, in particular to a device for inspecting a test piece. Background technique [0002] refer to figure 1 , an existing test strip device 10 includes a lower cover 11 , an upper cover 12 , and a test strip set 13 . The lower cover 11 is roughly rectangular and has several insertion cylinders 111 located on two long sides, and a fixing group 112 located in the middle. The upper cover 12 has several insertion posts 121 for inserting the insertion cylinders 111, and a sample injection hole 122 and an inspection window 123 located in the middle and aligned with the fixed group 112, the inspection test piece group 13 has a supporting block 131 detachably mounted on the fixed group 112, and a support block 131 fixed on the fixed group 112. Test strip 132 on support block 131 . [0003] When in use, the inspector first puts the test piece set 13 into the fixed set 112, then inserts the insertion post ...

AI Technical Summary

Problems solved by technology

[0004] Although the test piece device 10 has the above-mentioned functions, there are still the following problems: because the test piece set 13 is designed to be replaceable, in order to facilitate the assembly or detachment of the upper cover 12 and the lower cover 11, the insertion column 121 and the insertion cylinder 111 are generally in an intermediate fit or clearance fit, and after being used for a period of time, the insertion cylinder 111 will be stretched to produce hole expansion, resulting in the upper cover 12 and the lower cover 11 The bonding strength between them is not good, so, in the process of moving the test piece device 10, the upper cover 12 and the lower cover 11 are easily separated, which not only makes the sample easily contaminated and reduces the test accuracy, but also Occurrence of sample leakage and contamination of the tester
