Fig. 1 shows a cryopreservation pipe cap provided by an embodiment of the utility model, which comprises a cap body 1, wherein the top surface of the cap body 1 is provided with an inner hole 2, the upper part of the inner circumferential surface of the inner hole 2 is provided with a clamping structure matched with a cap opening bit in a clamping manner, the lower part of the inner circumferential surface is provided with a plurality of convex ribs 4 distributed at intervals in the circumferential direction, and the upper ends of the convex ribs 4 are provided with guide surfaces 5, so that the tops of the convex ribs 4 are of a structure with a small top and a large bottom; the clamping structure is a bulge or a groove.

The convex rib 4 is used for matching with the screwdriver head to stop rotating, namely, the screwdriver head stops rotating in the pipe cover through the convex rib 4 and drives the pipe cover to rotate together through the convex rib 4 to complete the opening and closing of the cover. The guide surface 5 at the top of the convex rib 4 guides when the screwdriver bit enters the cover body 1, and the guide surface 5 is a conical surface, so that the screwdriver bit can enter conveniently. The convex rib 4 is vertically arranged in a strip shape, and the surface facing the center of the cover body 1 is an arc surface.

The inner hole is a step hole, the clamping structure and the convex ribs are arranged on the inner peripheral surface of the large hole of the step hole, and the small-diameter hole of the step hole can be used for centering with the screwdriver head. The radial dimension of the convex rib 4 is smaller than the width of the step surface of the inner hole 2, so that the screw driver can be conveniently prevented from entering the screw driver when the screw driver is stressed to rotate, and the two side surfaces of the convex rib 4 are stress surfaces matched with the screw driver to screw the cap.

The clamping structure is a groove or a protrusion, the corresponding part on the screwdriver head can be a protrusion or a groove, the embodiment takes the case that the cover body is provided with a groove as an example, the screwdriver head is provided with a protrusion 9, the groove can be a ring groove 3, the ring groove 3 is a continuous ring groove or a segmented ring groove along the inner peripheral surface of the large hole, namely, the ring groove 3 can be a continuous complete ring groove or an incomplete ring groove segmented in the circumferential direction, and the clamping of the protrusion 9 can be realized.

Fig. 2 to 4 show that this embodiment provides a structure of uncapping, including uncapping batch head and as above the cryopreserved pipe cap, uncap batch head includes the body of rod 6, the outer peripheral face circumference interval distribution of the body of rod 6 lower extreme has a plurality of beads 11, bead 11 corresponds and is located between two adjacent protruding muscle 4, the outer peripheral face of the body of rod 6 lower extreme has and corresponds the complex to the block structure with the joint structure in the lid 1, the body of rod 6 to the block structure with the joint structure of lid 1 in the two, one is the recess, another is the arch with the recess joint.

The clamping structure is used as a groove, specifically can be a ring groove and the like, the opposite clamping structure is used as a bulge, the upper and lower clamping point positions of the batch head and the frozen pipe cap are determined through the bulge 9 on the batch head, namely, the axial positioning is realized, the bulge 9 is clamped into the ring groove 3, and meanwhile, the fixing effect with the pipe cap is also realized.

The lower extreme of bead 11 extends to body of rod 6 lower extreme terminal surface, and the lower extreme off-plate edge of the body of rod 6 is provided with chamfer 10, plays and leads positive effect, makes 11 lower extreme terminal surfaces of bead form the guide face, has the direction to keep away the sky effect, avoids the collision with protruding muscle 4, can get into between the adjacent protruding muscle 4 along guide face automatic correction when simultaneously again contacting with protruding muscle 4. The chamfers 10 may be rounded corners.

The lower extreme of the body of rod 6 has the section of uncapping 7, and the section of uncapping 7 is coaxial with the body of rod 6, bead 11 sets up at the outer peripheral face of the section of uncapping 7, and highly the same with section of uncapping 7, the diameter of the section of uncapping 7 is not more than the body of rod 6 diameter. The distance from the outer surface of the convex edge 11 to the central axis of the rod body 6 is less than the radius of the rod body 6. The cover opening section 7 can be set to be a polygon prism, a convex edge 11 is formed at each edge and used for screwing the cover, and each edge is arc-shaped.

The lower end of the uncapping section 7 is also provided with a centering section 8, the centering section 8 is coaxial with the uncapping section 7, the diameter of the centering section 8 is smaller than that of the uncapping section 7, a chamfer 10 is also arranged on the outer edge of the lower end face of the centering section 8, and the centering section 8 plays a centering role when the bit enters the pipe cover 7. The height of the centering section 8 is higher than that of the convex rib 4.

Protruding 9 is the bump, and when can the chucking fixed with carrying the pipe, the friction suitably reduces, and the card is gone into and is broken away from all more convenient smooth and easy, and protruding 9 also can adopt other structures certainly, and when adopting the bump, the bump specifically can be a cone, and its central line is for following body of rod 6 radially. All the bulges 9 are on the same circumference and are matched with the pipe cover to be clamped and fixed. The groove 3 can be slightly larger than the protrusion 9 to provide a hanging force and reduce friction when the protrusion 9 rotates in the groove 3.

The quantity of the convex ribs 11 can be the same as that of the convex ribs 4, when the screwdriver bit enters the cover body 1 downwards, the chamfer angle 10 of the centering section 8 is guided to be aligned, the screwdriver bit enters the small-diameter hole of the inner hole 2 of the cover body 1, and centering is conducted on the centering section 8. Highly being higher than protruding muscle 4 height to heart section 8, beginning to get into the back in the minor diameter hole to heart section 8, accomplishing the heart, opening lid section 7 this moment and beginning to get into the major diameter hole in, the chamfer 10 of opening lid section 7 plays the effect that the guide got into in the major diameter hole protruding muscle 4, dodges protruding muscle 4, and opening lid section 7 gets into the major diameter hole through protruding muscle 4 top guide surface 5, and chamfer 10 all can be the arc angle. If the convex rib 11 just supports to the convex rib 4 when the batch head descends, the guide surface 5 can guide the convex rib 11 to enter between two adjacent convex ribs 4, so that collision is avoided, and correction is guided.

No matter freeze and deposit the pipe size, the pore structure of 1 top surface of lid with criticize first adaptation can, so different specifications freeze and deposit the pore structure on the pipe lid of pipe all the same, criticize the head and can share completely. And can effectively avoid dropping, this structure is through thousands of tests, and the tube cap all does not drop.

The utility model is not limited to the above alternative embodiments, and any other various forms of products can be obtained by anyone in the light of the present invention, but any changes in shape or structure thereof, which fall within the scope of the present invention as defined in the claims, fall within the scope of the present invention.
