In the figure:

the anti-skid screw comprises a non-sealing end 1, a sealing end 2, a screw hole 3, a linear protrusion 4, a cylindrical hole 5, an inverted conical hole 6, an anti-skid screw protrusion 7, an annular groove 8, an external thread 9 and a central hole 10.

Detailed Description

The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.

As shown in fig. 1 to 3, the cryopreservation tube cap comprises a tube cap body, wherein the tube cap body comprises a sealing end 2 and a non-sealing end 1, the sealing end 2 is a part inserted into the cryopreservation tube and matched with the cryopreservation tube, and the non-sealing end 1 is a part exposed out of the cryopreservation tube.

As shown in fig. 6, the center of the top of the non-sealing end 1 is provided with a screwed hole 3, and the screwed hole 3 comprises an upper cylindrical hole 5 part and an inverted conical hole 6 which is connected with the bottom of the cylindrical hole 5 and is used for fixing and positioning the automatic equipment.

The inner wall of the screwing hole 3 is provided with at least two linear bulges 4 which radially protrude towards the center of the screwing hole 3. The linear protrusions 4 are uniformly arranged along the circumferential direction of the inner wall of the screwing hole 3. The linear protrusion 4 is semi-cylindrical, and the diameter of the semi-cylindrical shape is far smaller than the diameter of the screw hole 3 relative to the screw hole 3. When the automatic screwing equipment is screwed, the automatic screwing equipment firstly extends into the screwing hole 3 and is spread, and the linear protrusion 4 is semi-cylindrical and has a small diameter, so that the screwing equipment does not need to be adjusted in position or slightly rotated. The supporting claw of the screwing equipment is matched with the linear protrusion 4 to be tensioned so as to realize automatic screwing operation on the cover body. The universal matching performance of the screwing equipment is improved, namely the design form of the cover body of the same pipe cover is adopted to adapt to the screwing of various screwing equipment, and the selectivity of enterprises is improved.
