Description

Technical Field

[0001] The utility model relates to the technical field of tube covers for cryopreservation tubes, in particular to a tube cover for cryopreservation tubes adapted to a capping device. Background Art

[0002] The caps are threaded onto the ends of cryogenic tubes. To remove the caps from a batch of cryogenic tubes, several tubes are placed in a matrix in a cryobox and the caps are removed using a capping tool. To ensure the caps fit the capping tool, they are fitted with a suitable adapter.

[0003] For example, in the patent with the publication number CN207566100U, a "cryogenic tube cover for automated operation" is disclosed. Figure 1 The tube cap comprises a tube cap body 1, the upper end of which is provided with at least two radially inwardly concave arcuate grooves 2 and at least two radially outwardly convex linear grooves 3. All the arcuate grooves 2 are evenly distributed circumferentially, and all the linear grooves 3 are evenly distributed circumferentially. The radially inwardly concave arcuate grooves 2 are suitable for outward-facing capping tools with retracting gripping teeth, while the radially outwardly convex linear grooves 3 are suitable for inward-facing capping tools with outward-facing gripping teeth.

[0004] While the tube caps disclosed in the prior art are compatible with both types of capping tools, the densely packed cryotubes within the cryobox create a small distance between the tops of adjacent tube caps. This reduces the operating space for the outward-facing capping tool with its retractable gripping teeth when used, creating a risk of the capping tool accidentally hitting adjacent tube caps, hindering operational accuracy. Furthermore, the existing caps make it difficult to distinguish between different samples within cryotubes. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a cryotube cap adapted for a capping tool. The present invention can not only increase the operating space of the capping tool and improve the operating accuracy, but also facilitate differentiation.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cryotube cap adapted for a cap screwing device comprises a cap body, a step ring being provided at the upper end of the cap body, a plurality of first grooves distributed circumferentially on the inner side of the step ring, a plurality of partition plates distributed circumferentially on the outer side of the step ring, a second groove being provided between two adjacent partition plates, an avoidance surface being provided on the upper part of the partition plate on the side facing away from the step ring, the avoidance surface being an arcuate surface or an inclined surface, and a color identification ring being detachably connected to the outer side wall of the cap body.

[0008] Furthermore, a center groove is provided on the top surface of the tube cover body, and the center groove is communicated with the inner ring of the step ring.

[0009] Furthermore, a buckle is provided on the outer wall of the head end of the color identification ring, a clamping hole is provided on the tail end of the color identification ring, a deformation hole is provided on the hole wall of the clamping hole, and the buckle cooperates with the clamping hole.

[0010] Furthermore, the outer wall of the head end of the color identification ring is provided with a groove, and the tail end of the color identification ring is provided with a convex edge, which extends into the groove.

[0011] Furthermore, an annular groove is provided on the outer side wall of the tube cover body, and the color identification ring is provided in the annular groove.

[0012] Furthermore, the outer wall of the tube cover body is provided with a first anti-slip pattern, and the outer wall of the color identification ring is provided with a second anti-slip pattern.

[0013] Furthermore, a limiting block is provided on the groove wall of the annular groove, and a limiting groove is provided on the inner wall of the color identification ring, and the limiting block cooperates with the limiting groove.

[0014] The utility model has the beneficial effects:

[0015] 1. Because the partition plate used to separate and form the second groove is provided with a relief surface, which is a curved or inclined surface, the relief surface can increase the distance between the tops of two adjacent tube caps. When using an outward-facing capping tool with retractable gripping teeth, the operating space of the outward-facing capping tool is increased, reducing the risk of the capping tool accidentally hitting other adjacent tube caps, thereby improving operational accuracy.

[0016] Furthermore, when different samples are contained in the cryotubes, color identification rings of different colors can be installed on the outside of the tube cover body to distinguish them, which makes it easy to distinguish the tube covers and improves the flexibility of use.

[0017] 2. By setting a buckle at the head end of the color identification ring, setting a clamping hole at the tail end of the color identification ring, and setting a deformation hole on the hole wall of the clamping hole, the head and tail ends of the color identification ring can be easily connected and separated, which is conducive to improving the disassembly and assembly efficiency of the color identification ring on the tube cover body.

[0018] 3. By setting a groove at the head end of the color identification ring and a convex edge at the tail end of the color identification ring, a position for the worker to separate the head and tail ends of the color identification ring can be provided. The worker can hold the convex edge from the groove and pry it outward, which further facilitates the separation of the head and tail ends of the color identification ring and is conducive to further improving the efficiency of separating the color identification ring and the tube cover body.

[0019] 4. By providing an annular groove on the outer side of the tube cover body and arranging the color identification ring in the annular groove, the color identification ring can be prevented from protruding from the outer side of the tube cover body, making the structure more compact and thus reducing space occupation.

[0020] 5. By providing a first anti-slip pattern on the outside of the pipe cover body and a second anti-slip pattern on the outside of the color identification ring, workers can prevent slipping when manually screwing the pipe cover body, thereby improving operational reliability.

[0021] 6. By providing a limit block on the groove wall of the annular groove and a limit groove on the inner wall of the color identification ring, the color identification ring can be prevented from rotating around the annular groove, further improving the reliability when workers manually screw the pipe cover body.

Therefore, they should not be construed as limiting the present invention.

[0037] Example:

[0038] See also Figures 2 to 8 A cryotube cap adapted for a cap screwing device comprises a cap body 1.

[0039] See also Figure 2 A step ring 4 is provided at the upper end of the pipe cover body 1 , and the step ring 4 and the pipe cover body 1 are an integral structure.

[0040] See also Figure 2 The inner side of the step ring 4 is provided with a plurality of first grooves 5 distributed along the circumferential direction.

[0041] See also Figure 2 Multiple circumferentially distributed partition plates 6 are provided on the outside of the step ring 4. The partition plates 6 are integrally formed with the step ring 4 and the pipe cover body 1. A second groove 7 is provided between two adjacent partition plates 6. A relief surface 8 is provided on the upper portion of the partition plate 6, facing away from the step ring 4. The relief surface 8 is an arcuate or inclined surface.

[0042] See also Figure 8 The top surface of the pipe cover body 1 is provided with a central groove 9 , and the central groove 9 is connected to the inner circle of the step ring 4 .

[0043] See also Figure 2 and Figure 3 The outer side wall of the tube cover body 1 is detachably connected with a color identification ring 10.

[0044] See also Figures 9 to 12The outer wall of the head end of the color identification ring 10 is provided with a buckle 11, which is an integral structure with the color identification ring 10. The tail end of the color identification ring 10 is provided with a clamping hole 12, and the hole wall of the clamping hole 12 is provided with a deformation hole 13, and the buckle 11 cooperates with the clamping hole 12.

[0045] See also Figure 9 and Figure 11 The outer wall of the head end of the color identification ring 10 is further provided with a groove 14 , and the tail end of the color identification ring 10 is provided with a convex edge 15 , which extends into the groove 14 .

[0046] See also Figure 4 , the outer wall of the tube cover body 1 is provided with an annular groove 16, see Figure 2 A color identification ring 10 is provided in the annular groove 16 .

[0047] The outer wall of the tube cover body 1 is provided with a first anti-slip pattern, and the outer wall of the color identification ring 10 is provided with a second anti-slip pattern.

[0048] See also Figure 4 A stopper 17 is provided on the wall of the annular groove 16. The stopper 17 and the pipe cover body 1 are an integral structure. Figure 9 The inner wall of the color identification ring 10 is provided with a limiting groove 18 , and the limiting block 17 cooperates with the limiting groove 18 .

[0049] In this embodiment, the assembly of the color identification ring 10 and the tube cover body 1 works as follows: First, the worker encloses the color identification ring 10 in the annular groove 16 on the outside of the tube cover body 1, making sure that the stop groove 18 is correspondingly buckled onto the stop block 17; then, the worker presses the rear end of the color identification ring 10 toward the front end, so that the buckle 11 is squeezed into the locking hole 12. At this point, the end of the color identification ring 10 is connected, and the color identification ring 10 and the tube cover body 1 are assembled. During the process of the buckle 11 squeezing into the locking hole 12, the hole wall of the locking hole 12 is adaptively deformed because the deformation hole 13 is provided on the hole wall of the locking hole 12.

[0050] In this embodiment, the detachment of the color identification ring 10 from the pipe cap body 1 works as follows: a worker grasps the protruding edge 15 at the groove 14 and forcefully bends the protruding edge 15 outward, causing the tail end of the color identification ring 10 to bend outward away from the leading end, thereby allowing the buckle 11 to exit the locking hole 12, thus separating the color identification ring 10 from its leading and trailing ends. The worker then removes the color identification ring 10 from the pipe cap body 1. During the process of the buckle 11 exiting the locking hole 12, the wall of the locking hole 12 is adaptively deformed because the deformation hole 13 is provided in the wall of the locking hole 12.

[0051] The adaptation principle of the tube cap and the cap screwing tool of this embodiment is as follows: the first groove 5 can be adapted to an inward-facing cap screwing tool with outward-facing grabbing teeth, and the second groove 7 can be adapted to an outward-facing cap screwing tool with retracted grabbing teeth.

[0052] In the tube cap of this embodiment, because the partition plate 6 used to separate and form the second groove 7 is provided with a clearance surface 8, which is a curved or inclined surface, the clearance surface 8 can increase the distance between the tops of two adjacent tube caps. When using an outward-facing capping tool with retractable gripping teeth, the operating space of the outward-facing capping tool is increased, reducing the risk of the capping tool accidentally hitting other adjacent tube caps, thereby improving operational accuracy.

[0053] Furthermore, when different samples are contained in the cryotubes, color identification rings 10 of different colors can be installed on the outer side of the tube cover body 1 to distinguish them, which makes it easier to distinguish the tube covers and improves the flexibility of use.

[0054] By setting a buckle 11 at the head end of the color identification ring 10, setting a clamping hole 12 at the tail end of the color identification ring 10, and setting a deformation hole 13 on the hole wall of the clamping hole 12, the head and tail ends of the color identification ring 10 can be easily connected and separated, which is beneficial to improving the disassembly and assembly efficiency of the color identification ring 10 on the tube cover body 1.

[0055] By providing a groove 14 at the head end of the color identification ring 10 and a convex edge 15 at the tail end of the color identification ring 10, a position for bending can be provided for workers to separate the head and tail ends of the color identification ring 10. The worker can just hold the edge 15 at the groove 14 and bend it outward, which further facilitates the separation of the head and tail ends of the color identification ring 10 and is conducive to further improving the efficiency of separating the color identification ring 10 and the tube cover body 1.

[0056] By providing an annular groove 16 on the outer side of the tube cover body 1 and arranging the color identification ring 10 in the annular groove 16, the color identification ring 10 can be prevented from protruding from the outer side of the tube cover body 1, making the structure more compact and thus reducing space occupation.

[0057] By providing a first anti-slip groove on the outer side of the pipe cover body 1 and a second anti-slip groove on the outer side of the color identification ring 10 , workers can prevent slipping when manually screwing the pipe cover body 1 , thereby improving operational reliability.

[0058] By providing a limit block 17 on the groove wall of the annular groove 16 and a limit groove 18 on the inner wall of the color identification ring 10, the color identification ring 10 can be prevented from rotating around the annular groove 16, further improving the reliability when workers manually screw on the pipe cover body 1.

[0059] In addition, the presence of the central groove 9 enables the capping tool to quickly position the grabbing teeth through the rapid positioning of the central positioning pin, thereby making the capping operation more accurate.

[0060] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
