Description

Technical Field

[0001] The utility model relates to the technical field of biological sample storage, in particular to a plate frame structure. Background Art

[0002] The plate rack is a box structure. The plate holder is provided with a plurality of holes for inserting cryotubes.

[0003] For example, in the patent with the publication number CN207029855U, a "freezing box" is disclosed. Fig.11 and Fig.12 As shown, the patent includes a box cover 2 and a box body 1, and the box body 1 is provided with a plurality of bearing holes 11 distributed in a rectangular array, the cross-section of the bearing holes 11 is a regular polygon, and the bearing holes 11 are provided with a limiting portion 111 for fixing the bottom of the cryopreservation tube at a preset height; the box cover 2 is connected to the box body 1 through an opening and closing buckle; the opening and closing buckle includes buckle holes 31 arranged on the left and right sides of the upper part of the box body 1, and the buckle holes 31 can be gourd-shaped holes, and the box cover 2 is provided with slide grooves (not shown in the figure) on the left and right sides of the lower part, and a slide rod (not shown in the figure) is slidably connected in the slide groove, and a shift block 32 is provided at one end of the slide rod, and a slider 33 is provided at the other end of the slide rod; when closing the cover, the slider 33 is inserted from the wider part of the buckle hole 31, and then the shift block 32 is slid to make the slider 33 stuck in the narrower part of the buckle hole 31, so that the cover can be closed.

[0004] From the above introduction, it can be seen that in the existing plate rack (i.e., the box body), the bearing holes are closely arranged together, and the freezing tubes inserted in the bearing holes are also closely arranged together, making the insertion and removal space small and inconvenient for experimenters to insert and remove the freezing tubes. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a plate frame structure. The utility model can increase the plugging and unplugging space, making it convenient for experimenters to perform the operations of plugging and unplugging cryopreservation tubes.

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

[0007] A plate frame structure includes a plate frame body, which includes a plurality of monomers arranged along the left-right direction, the leftmost monomer and the rightmost monomer are both provided with buckle holes, each monomer is provided with a row of bearing holes, two adjacent monomers are slidably connected along the vertical direction, and a single groove is provided on the front and rear sides of the bottom of the plurality of monomers, the single grooves on the front sides of the bottoms of all monomers and the single grooves on the rear sides of the bottoms of all monomers are connected to form a receiving groove, a support rod is provided in the receiving groove, and the left end of the support rod is rotatably connected to the left end of the receiving groove.

[0008] Furthermore, in two adjacent monomers, the front and rear side walls of the monomer located on the right are provided with guide holes, the left side wall of the monomer located on the right is provided with an insertion hole, the insertion hole is connected to the guide hole, and the right side wall of the monomer located on the left is provided with a guide block, the guide block is inserted into the insertion hole and the guide hole in sequence, and the insertion hole and the guide hole are both vertically slidably matched with the guide block.

[0009] Furthermore, a stop convex portion and a first deformation hole are provided at the right end of the guide block, and the stop convex portion abuts against the hole wall of the guide hole.

[0010] Furthermore, mounting holes are provided on both the front and rear sides of the leftmost unit, and the mounting holes are connected to the left end of the accommodating groove. A rotating shaft is provided on the groove wall at the left end of the accommodating groove, and a limiting cone is provided on the outer periphery of the end of the rotating shaft. The limiting cone is provided with a plurality of second deformation holes along the circumferential direction, and a rotating hole is provided on the left end of the support rod, and the rotating hole cooperates with the rotating shaft.

[0011] Furthermore, a blocking protrusion is provided on the right end groove wall of the accommodating groove, and the right end of the supporting rod cooperates with the blocking protrusion.

[0012] Furthermore, an expansion groove is provided at the right end of the accommodating groove, and a lever protrusion is provided at the right end of the supporting rod, and the lever protrusion is arranged in the expansion groove.

[0013] The utility model has the beneficial effects:

There is no interference from other freezing tubes on the right side of each row of freezing tubes, which increases the insertion and removal space of each row of freezing tubes, making it convenient for experimenters to insert and remove freezing tubes.

[0015] 2. Because two adjacent rows of bearing holes can be staggered in the vertical direction, a height difference occurs between two adjacent rows of freezing tubes, so that the vertical space can be fully utilized, avoiding excessive occupation of horizontal space, thereby improving space utilization.

[0016] 3. By setting an insertion hole and a guide hole on the right monomer, setting a guide block on the left monomer, and setting a first deformation hole and a stop convex portion on the guide block, a detachable connection between two adjacent monomers on the left and right can be achieved, which is convenient for partial replacement of a monomer and replacement and maintenance.

[0017] 4. By setting a mounting hole on the leftmost unit and setting a limiting cone and a second deformation hole at the end of the rotating shaft, it is easy to assemble the support rod into the accommodating groove, which is conducive to improving assembly efficiency.

[0018] 5. By arranging a blocking convex portion on the groove wall at the right end of the accommodating groove, when the support rod is completely accommodated in the accommodating groove, the right end of the support rod can be blocked by the blocking convex portion to prevent the right end of the support rod from falling out of the accommodating groove, thereby improving the stability of the support rod accommodated in the accommodating groove.

[0019] 6. By setting an expansion groove at the right end of the accommodating groove and a lever protrusion at the right end of the support rod, employees can insert their fingers into the expansion groove to hold the lever protrusion.

[0038] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] Example:

[0040] like Figure 1-Figure 10 As shown, a frame structure includes a frame body, the frame body includes a plurality of monomers 4 arranged along the left-right direction, the leftmost monomer 4 and the rightmost monomer 4 are both provided with buckle holes 31, and each monomer 4 is provided with a row of bearing holes 11.

[0041] like Figure 7 and 9 As shown, in two adjacent monomers 4, the front and rear side walls of the monomer 4 located on the right are provided with guide holes 41, and the left side wall of the monomer 4 located on the right is provided with an insertion hole 42, and the insertion hole 42 is connected with the guide hole 41; the right side wall of the monomer 4 located on the left is provided with a guide block 43, and the right end of the guide block 43 is provided with a stop protrusion 431 and a first deformation hole 432, and the stop protrusion 431 and the guide block 43 are an integral structure.

[0042] like Figure 7 and 9As shown, when assembling two adjacent monomers 4: (1) align the guide block 43 on the left monomer 4 with the insertion hole 42 on the right monomer 4. (2) push the left monomer 4 with force, so that the guide block 43 on the left monomer 4 is squeezed into the insertion hole 42 and the guide hole 41 in turn; when the stop convex portion 431 at the right end of the guide block 43 is squeezed into the insertion hole 42, the first deformation hole 432 is adaptively deformed (i.e., becomes smaller); when the stop convex portion 431 enters the guide hole 41, the first deformation hole 432 is restored, and at this time the stop convex portion 431 abuts against the left hole wall of the guide hole 41, so that the two adjacent monomers 4 on the left and right cannot be easily separated, and the assembly of the two adjacent monomers 4 is completed.

[0043] like Figure 7 and 9 As shown, when separating two adjacent monomers 4: (1) Press the stop convex portion 431 from the guide hole 41 to allow the stop convex portion 431 to squeeze the first deformation hole 432, so that the first deformation hole 432 becomes smaller. (2) Push the stop convex portion 431 to the left to allow the stop convex portion 431 to exit the insertion hole 42, and the two adjacent monomers 4 can be separated.

[0044] like Figure 7 As shown, when two adjacent monomers 4 slide relative to each other in the vertical direction, the guide block 43 on the left monomer 4 slides in the vertical direction in the insertion hole 42 and the guide hole 41 of the right monomer 4, and the length of the guide hole 41 in the vertical direction limits the sliding distance of the guide block 43 in the vertical direction.

[0045] like Figure 2 As shown, a plurality of monomers 4 have single grooves 44 on both the front and rear sides of the bottom, all the single grooves 44 located at the front side of the bottom of the monomer 4 are connected to form a receiving groove, and all the single grooves 44 located at the rear side of the bottom of the monomer 4 are also connected to form a receiving groove.

[0046] like Figure 2 and Figure 3 As shown, the front and rear sides of the leftmost unit 4 are provided with mounting holes 45, and the mounting hole 45 is connected to the left end of the accommodating groove. A rotating shaft 46 is provided on the groove wall at the left end of the accommodating groove, and a limiting cone 461 is provided on the outer periphery of the end of the rotating shaft 46. The limiting cone 461 and the rotating shaft 46 are an integral structure, and the limiting cone 461 is provided with a plurality of second deformation holes 462 along the circumferential direction.

[0047] like Figure 4 and Figure 5 As shown, a blocking protrusion 47 is provided on the groove wall at the right end of the accommodating groove, and an expansion groove 48 is also provided at the right end of the accommodating groove.

[0048] like Figure 2 As shown, a support rod 5 is provided in the receiving groove. Figure 3 As shown, the left end of the support rod 5 is provided with a rotation hole 51. The rotation hole 51 is used to cooperate with the rotating shaft 46. Figure 4 and Figure 5 As shown, the right end of the support rod 5 is provided with a lever protrusion 52 , and the lever protrusion 52 and the support rod 5 are an integral structure.

[0049] like Figure 3 As shown, when installing the support rod 5 into the receiving groove: (1) align the rotating hole 51 at the left end of the support rod 5 with the limiting cone 461. (2) Push the support rod 5 with force to fit the rotating hole 51 onto the limiting cone 461. When the limiting cone 461 is squeezed into the rotating hole 51, the limiting cone 461 is retracted and gathered, and the adaptability of the second deformation hole 462 becomes smaller, until the limiting cone 461 completely passes through the rotating hole 51. The limiting cone 461 and the second deformation hole 462 are restored, and the rotating hole 51 is fitted on the rotating shaft 46. The limiting cone 461 can prevent the rotating shaft 46 from escaping from the rotating hole 51.

[0050] like Figure 4 and Figure 5 As shown, when the support rod 5 is completely accommodated in the accommodating groove, the right end of the support rod 5 is blocked by the blocking protrusion 47. The blocking protrusion 47 can prevent the right end of the support rod 5 from falling out of the accommodating groove, thereby improving the stability of the support rod 5 accommodated in the accommodating groove.

[0051] like Figure 2 and Figure 6 As shown, when the support rod 5 is completely received in the receiving groove, all the monomers 4 are at the same level.

[0052] like Figure 4 and Figure 5 As shown, when the right end of the support rod 5 needs to be taken out from the receiving groove: the employee can insert a finger into the expansion groove 48, grab the lever protrusion 52 located in the expansion groove 48, overcome the blocking force of the blocking protrusion 47 on the support rod 5, and forcefully pull the lever protrusion 52 out of the expansion groove 48, so that the right end of the support rod 5 can be taken out from the receiving groove.

[0053] In addition, the rotating hole 51 and the rotating shaft 46 are interference fit. When the support rod 5 is rotated around the rotating shaft 46, the support rod 5 needs to be pulled forcefully. When the support rod 5 stops rotating, the friction between the rotating hole 51 and the rotating shaft 46 can be used to stabilize the state of the support rod 5 after rotation.

[0054] like Fig.10 As shown, when the insertion and extraction space needs to be increased, the following operations are performed: (1) In each of two adjacent monomers 4, the left monomer 4 is slid upward relative to the right monomer 4, so that there is a height difference between the two adjacent rows of bearing holes 11, and there is a height difference between the two adjacent rows of freezing tubes inserted in the bearing holes 11. (2) The support rod 5 is rotated out of the receiving groove, and the right end of the support rod 5 is abutted against the table surface of the workbench to keep the entire rack structure balanced.

[0055] Because there is a height difference between two adjacent rows of cryogenic tubes, there is no interference from other cryogenic tubes on the right side of each row of cryogenic tubes, which increases the plugging and unplugging space of each row of cryogenic tubes and facilitates the experimenters to insert and unplug the cryogenic tubes.

[0056] Because two adjacent rows of bearing holes 11 can be staggered in the vertical direction, a height difference appears between two adjacent rows of freezing tubes, so that the vertical space can be fully utilized, avoiding excessive occupation of horizontal space, thereby improving space utilization.

[0057] By setting an insertion hole 42 and a guide hole 41 on the right monomer 4, setting a guide block 43 on the left monomer 4, and setting a first deformation hole 432 and a stop protrusion 431 on the guide block 43, a detachable connection between two adjacent monomers 4 on the left and right can be achieved, which is convenient for partial replacement of a monomer 4 and replacement and maintenance.

[0058] By providing a mounting hole 45 on the leftmost unit 4 and providing a limiting cone 461 and a second deformation hole 462 at the end of the rotating shaft 46, it is possible to facilitate assembly of the support rod 5 into the accommodating groove, which is beneficial to improving assembly efficiency.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
