Description

Technical Field

[0001] This invention belongs to the field of reagent kit technology, and more specifically, relates to a fixation structure for a thrombin assay reagent kit. Background Technology

[0002] When thrombin is measured, test tubes are used for storage, and batches of test tubes are then packed in test tube boxes. In order to ensure the stability of the test tubes during transportation, test tube boxes with a fixed structure are needed to store the test tubes.

[0003] Based on the above, the current test tube boxes use a simple slot structure for fixing, in which test tubes are inserted into the slots for fixation. However, there may be gaps between the test tubes and the slots, and the size of the holes in the existing test tube boxes cannot be adjusted, making it inconvenient to use different types of test tubes for fixing and installation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a fixing structure for a thrombin assay kit, which solves the problem mentioned in the background art that the fixing structure used in existing test tube boxes is a simple slot structure, in which test tubes are inserted into the slots for fixing. However, there may be gaps between the test tubes and the slots, and the size of the holes in existing test tube boxes cannot be adjusted, making it inconvenient to use different types of test tubes for fixing and installation.

[0005] The purpose and effect of the fixed structure of the thrombin assay kit of this utility model are achieved by the following specific technical means:

[0006] A fixation structure for a thrombin assay kit includes a main box body. A magnetic block is fixedly installed at the center of the front top of the main box body. A rotating cover is hinged to the top of the main box body, and a trapezoidal iron block is fixedly installed at the center of the lower front side of the rotating cover. Four sets of threaded posts are integrally installed at the lower corners of the interior of the main box body, and each threaded post is connected to an assembly screw via a threaded connection. A positioning plate is slidably installed inside the main box body, and an annular screw hole is arrayed in the center of the positioning plate. Four sets of through holes are opened at the corners of the positioning plate, and the assembly screw is located outside the through holes and does not contact the through holes. A T-shaped threaded annular seat is installed in the annular screw hole via a threaded connection.

[0007] Furthermore, a rubber top pad is fixedly installed inside the rotating cover; a rubber bottom pad is fixedly installed inside the lower part of the main box.

[0008] Furthermore, spring ring grooves for installing springs are provided on the upper and lower sides of the positioning plate at positions outside the through-hole. Springs are provided in the upper and lower spring ring grooves, as well as in the lowermost spring ring groove and outside the threaded post.

[0009] Furthermore, a transverse groove is provided on the top of the threaded ring seat.

[0010] Furthermore, an air bladder is fixedly provided on the inner wall of the threaded ring seat; a circular hole is provided on the threaded part of the threaded ring seat, and a valve core is fixedly provided in the circular hole, the valve core not exceeding the inner diameter of the threaded ring seat.

[0011] Furthermore, a hand-rolled nut is provided on the outside of the assembly screw via a threaded connection, and the outer periphery of the hand-rolled nut is corrugated; the hand-rolled nut can contact the surface of the positioning plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention employs a double buffer structure to enhance safety protection. The airbag wraps around the test tube, providing elastic fixation and cushioning. Combined with the bottom rubber pad, it can absorb vibration and impact from all directions during loading and transportation, and can also prevent gaps between the test tube and the slot, thus improving stability. The top rubber pad ensures that the test tube is sealed, preventing liquid leakage and maximizing the safety of the test tube.
