Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are used in a broad sense, and for example, "connected," may be fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements.

Referring to fig. 1-2, a seal-capping device for a PCR tube includes: a rolled portion 1 and a grip portion 2;

the rolling part 1 is arranged at the lower end of the holding part 2, and one end, far away from the holding part 2, of the rolling part 1 is an arc-shaped surface 11; the arc-shaped surface 11 is provided with a plurality of grooves 12 along the width direction, and the grooves 12 are sunken along the direction close to the holding part 2 and extend along the arc length direction of the arc-shaped surface 11; the two sides of the arc-shaped surface 11 in the width direction are respectively provided with a baffle 13, and the lower end surface of the baffle 13 protrudes outwards from the arc-shaped surface 11 and is parallel to the arc-shaped surface 11. In this embodiment, the number of the grooves 12 is four.

The sealing and capping device for the PCR tube adopts the principle that the arc surface is tangent to the straight line, the pressure generated when the 8-connection tube is rolled by the arc surface and used for sealing the cap strip is concentrated on one cap, the pressure is 5-10 times higher than that generated when the cap strip is pressed by a single finger, and meanwhile, the arc surface is rolled back and forth, and the force is uniform and controllable. Moreover, the cambered surface of the rolling part 1 is designed with 4 small grooves 12, so that the inosculation of the pressing contact surface can be improved. Convex edges are designed on two sides of the cambered surface of the rolling part 1 so as to ensure that the moving track during rolling is consistent with the central axis and drive the packaging cover strip not to deviate.

In order to roll a plurality of lids simultaneously, the rolled sections 1 are provided with coupling means along both sides of the width direction of the arc-shaped face 11, respectively, for coupling the sub-rolled sections 3 to form two or more rolled sections 1 in parallel. Therefore, 1-3 rolling parts 1 can be formed in a combined mode according to the requirements of operators, and a plurality of pressing covers can be packaged at the same time.

In order to realize the quick connection and disassembly of the sub-rolling parts 3, the connecting parts are screw holes, and the sub-rolling parts 3 are connected with the screw holes through bolts. In this embodiment, the number of the screw holes is three, and the screw holes are arranged at intervals along the length direction of the side surface.

Further, the arc-shaped faces 11 of the sub-rolled portions 3 are provided with a baffle 13 on one side in the width direction, respectively. Thus, after the installation of the sub-rolling parts 3 is completed, one side close to the other rolling part 1 can share one baffle 13, and one baffle 13 is reduced.

Finally, the section of the holding part 2 along the height direction comprises an arc surface and two vertical surfaces; the lower end of the arc surface is provided with an opening, and the vertical surfaces are connected to two ends of the opening.

The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
