Description

Technical Field

[0001] The utility model belongs to the technical field of reagent pens, in particular to a testing device for reagent pens. Background Art

[0002] A reagent pen is a pen-type item used to store reagents. The reagent pen is mainly composed of three parts: a pen barrel, a push rod and a pen tip. The push rod is inserted into the inside of the pen barrel and contacts the inner wall of the pen barrel through the rubber head to ensure that the reagent stored in the pen barrel can be pushed out of the pen tip when the push rod is subjected to force. During the production process, the reagent pen also needs to be tested for its performance to ensure that the reagent pen can be used for storing and pushing reagents.

[0003] After the existing reagent pen is produced, it uses the method of manually pushing the push rod back and forth to test the reagent pen, that is, the tester uses the feel of pushing the push rod to judge whether the reagent pen meets the production requirements. This test method is not accurate and will cause the problem of result error due to different testers; and when performing performance testing on the test pen, it can only push and pull test one test pen at a time, and cannot test in batches, so it cannot meet the production speed requirements. To this end, we provide a test device for a reagent pen to solve the above problems. Utility Model Content

[0007] The utility model is further configured such that a test slot is provided in the test box, and the inner side wall of the test slot cooperates with the outer peripheral side wall of the pad, and three groups of positioning columns are provided on the pad, and each group of positioning columns corresponds to one of the bottom plates.

[0008] The utility model is further configured such that positioning holes are provided at both ends of the base plate, and the base plate is plugged into the positioning columns through the positioning holes. A through hole is also provided on the base plate, and three through holes are arranged on the base plate at equal intervals, and a test component is arranged corresponding to each through hole.

[0009] The utility model is further configured such that side grooves are provided at four quadrant points of the inner side wall of the penetration hole, the base plate is connected to the clamp in the test assembly through the side grooves, the tail of the spring in the clamp is adhesively connected to the connecting ring, and the connecting ring is threadedly connected to the inner wall of the side groove.

[0010] The utility model is further configured that the clamping plate in the clamping member is configured in an arc-shaped structure, and an anti-slip pad is bonded to the outer wall of the clamping plate, and the outer peripheral side wall of the clamping plate is also matched with the inner wall of the side groove.

[0011] The utility model is further configured such that a circular groove is provided on the upper outer side of the through hole of the bottom plate, and the bottom plate is threadedly connected to the bottom ring in the lifting member through the circular groove, the bottom ring has the same caliber as the top ring, and the top ring and the bottom ring are arranged parallel to each other.

[0012] The utility model is further configured such that there are four pneumatic rods on the bottom ring, the four pneumatic rods are arranged in a ring array structure, and the latex pad on the pad is arranged in a flat structure directly below the test component.

[0013] The utility model has the following beneficial effects:

[0014] The utility model has nine test components in total, and each three form a group. The nine test components are all arranged inside the test box and can work simultaneously. When in use, it is only necessary to insert the pen tips of nine reagent pens downwards into the pad, and then close the cover of the test box to carry out unified testing, thereby realizing batch unified testing.

[0015] The utility model is provided with a bottom plate, a test assembly and a pad, wherein the bottom plate is used for installing the test assembly, and one bottom plate can be used for installing three test assemblies, and a pad is also provided at the bottom of the bottom plate, and a latex pad for contacting with the pen tip of the test pen is bonded to the side wall of the pad, so that when the pen tip of the test pen contacts it, the latex pad can be better wrapped with the latex pad due to its soft texture, and the hole of the pen tip can also be sealed and blocked. When in use, the pen tip of the reagent pen to be tested is inserted downward into the test assembly, and the clamping piece in the test assembly will clamp the pen barrel of the reagent pen, and then after the cover plate is closed, the lifting piece in the test assembly will gradually rise and gradually contact with the reagent pen The hand-held wing plate at the tail of the push rod contacts the bottom of the hand-held wing plate, and then continues to move upward. When the rubber pad at the head of the push rod of the reagent pen is well sealed with the pen barrel, the pen tip is blocked by the latex pad, and it is difficult to intake air from the pen tip. Therefore, the outward extension length of the push rod lifted by the pneumatic rod is limited. When the pressure sensor just above the corresponding test component senses the pressure brought by the hand-held wing plate at the tail of the push rod, that is, the hand-held wing plate at the tail of the push rod contacts it, the feedback light on its top flashes. At that time, it is judged that the reagent pen in the test component has poor sealing, otherwise the reagent pen is judged to be qualified. The whole process only requires the input and removal of the reagent pen and does not require too much manual participation.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
