Abstract
Description
Technical Field
[0001] This utility model relates to the field of cell culture technology, specifically a cell culture dish shelf. Background Technology
[0002] In cell culture experiments, racks are commonly used equipment for storing test tubes.
[0003] Currently, when the shelf is shaken by external force, the test tubes placed inside are very easy to shake, causing the liquid inside the test tubes to leak out. This not only causes sample loss but may also contaminate the experimental environment and affect the accuracy of experimental results. In addition, the test tubes are mostly made of glass, which is fragile. When placed on the shelf, there is a lack of effective cushioning and fixing measures, making them easy to break due to impact.
[0004] To address this issue, a cell culture dish shelf is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a cell culture dish shelf that effectively fixes test tubes and buffers against impacts, solving the problems of test tubes easily shaking and leaking when subjected to external force and easily breaking due to impacts during placement in traditional shelves.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cell culture dish holder, comprising an outer frame, an inner frame installed inside the outer frame, the inner frame being used for holding test tubes, the inner frame including an inner support frame, the inner support frame being rotatably installed with the outer frame via a connecting shaft, the inner support frame having a reserved hole, a sleeve being installed below the reserved hole, and a positioning sleeve being installed at the bottom of the sleeve, the positioning sleeve being used for positioning and inserting test tubes.
[0007] Preferably, the outer frame includes an outer support frame, with holes on the upper sides of the outer support frame for inserting bearings, mounting holes at the bottom of the outer support frame, and anti-slip pads installed at the bottom of the outer support frame.
[0008] In the design, holes are opened on the upper sides of the outer support frame in the outer frame and bearings are embedded therein. There are mounting holes at the bottom and anti-slip pads are installed at the bottom. This design realizes the functional basis of stable support and flexible connection of the outer frame.
[0009] The outer support frame, as the main structure of the outer frame, has the ability to support the inner frame and test tubes;
[0010] The embedded installation of the bearing provides the conditions for the rotational connection between the inner support frame and the outer support frame;
[0011] The mounting holes are specifically designed for the installation and fixing of the anti-slip pad. The anti-slip pad is made of soft rubber and has a diamond-shaped anti-slip texture on the bottom, which can significantly enhance the friction between the shelf and the surface on which it is placed, effectively preventing the shelf from shaking or shifting.
[0012] Preferably, the bearing is used in conjunction with the connecting shaft to connect the inner support frame and the outer support frame.
[0013] In the design, the bearings and connecting shafts work together to connect the inner support frame and the outer support frame, enabling the inner frame to rotate relative to the outer frame.
[0014] This connection method offers excellent rotational flexibility and stability, effectively reducing frictional losses during rotation and ensuring that the inner support frame rotates smoothly around the bearing under the action of the connecting shaft, making it convenient for operators to access test tubes.
[0015] Preferably, the mounting hole is used for installing the anti-slip mat, which is made of soft rubber and has a diamond-shaped anti-slip pattern on the bottom.
[0016] In the design, the mounting holes at the bottom of the outer support frame are used for the installation of anti-slip pads, achieving a stable connection between the anti-slip pads and the outer frame.
[0017] The outer support frame secures the anti-slip pad to the bottom through mounting holes. The anti-slip pad is made of soft rubber and features a unique diamond-shaped anti-slip pattern on its bottom, which increases the contact resistance with the table or other flat surfaces, providing excellent anti-slip performance. This effectively prevents the shelf from shifting unnecessarily due to external forces during experimental operations, ensuring experimental safety.
[0018] Preferably, a counterweight rod is fixedly installed on the bottom inner side of the inner support frame, and the counterweight rod is used to counterweight the inner support frame.
[0019] In the design, a counterweight rod is fixedly installed at the bottom of the inner side of the inner support frame, which realizes the adjustment and balance of the center of gravity of the inner support frame.
[0020] The counterweight plays an important role in adjusting the center of gravity of the inner support frame. When the test tube is placed in the inner frame or the inner support frame and rotated, the counterweight can effectively maintain the balance and stability of the inner support frame by properly distributing the weight, preventing the inner frame from tipping over due to the shift in the center of gravity, and improving the safety of the shelf.
[0021] Preferably, the positioning sleeve adopts a funnel-shaped structure design, the positioning sleeve is made of soft rubber material, and the inner wall of the positioning sleeve is provided with horizontal anti-slip texture.
[0022] In the design, the positioning sleeve adopts a funnel-shaped structure, is made of soft rubber, and has horizontal anti-slip texture on the inner wall, which realizes the precise positioning and stable fixation of the test tube.
[0023] The funnel-shaped positioning sleeve guides the test tube to be inserted quickly and accurately, helping operators to place the test tube in the designated position quickly; the soft rubber positioning sleeve provides cushioning protection when fixing the test tube, preventing the glass test tube from breaking due to rigid contact.
[0024] The horizontal anti-slip texture on the inner wall increases the friction between the positioning sleeve and the outer wall of the test tube, further preventing the test tube from shaking or slipping during placement, and ensuring the stability and safety of the test tube placement.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0026] This invention achieves the effect of effectively fixing the test tube and buffering impacts by setting a positioning sleeve, a sleeve and a reserved hole.
[0027] The positioning sleeve is used for positioning and inserting test tubes. Its structure can accurately limit the bottom of the test tube, effectively preventing the test tube from shaking when the shelf is subjected to external force, thereby avoiding liquid leakage.
[0028] Meanwhile, the positioning sleeve, together with the sleeve, forms a wrapping and buffering structure during the insertion of the test tube. The design of the sleeve connecting with the reserved hole disperses the force when the test tube is inserted. In addition, the sleeve and positioning sleeve can be made of materials with cushioning properties, which can effectively buffer the impact when the test tube is placed, solving the problems of test tubes easily shaking and leaking when subjected to external force and easily breaking due to impact during the placement process in traditional racks.
[0029] The inner and outer frames are rotatably installed, allowing the inner frame to be rotated flexibly when test tubes need to be retrieved, reducing the risk of bumps and knocks caused by frequent handling of test tubes. At the same time, under the action of gravity, the problem of leakage caused by shaking of test tubes is avoided, further ensuring the safety of test tube placement and use.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Example 1
[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a cell culture dish holder, including an outer frame 1, an inner frame 2 installed inside the outer frame 1, the inner frame 2 being used to hold test tubes, the inner frame 2 including an inner support frame 21, the inner support frame 21 being rotatably installed with the outer frame 1 via a connecting shaft 22, the inner support frame 21 having a reserved hole 23, a sleeve 24 being installed below the reserved hole 23, and a positioning sleeve 25 being installed at the bottom of the sleeve 24, the positioning sleeve 25 being used for positioning and inserting test tubes.
[0038] Specifically, by setting the positioning sleeve 25, the sleeve 24 and the reserved hole 23, the test tube is effectively fixed and the impact is buffered.
[0039] The positioning sleeve 25 is used for positioning and inserting test tubes. Its structure can accurately limit the bottom of the test tube, effectively preventing the test tube from shaking when the shelf is subjected to external force, thereby avoiding liquid leakage.
[0040] Meanwhile, the positioning sleeve 25, together with the sleeve 24, forms a wrapping and buffering structure during the insertion of the test tube. The design of the sleeve 24 being connected to the reserved hole 23 makes the force distributed when the test tube is inserted. In addition, the sleeve 24 and the positioning sleeve 25 can be made of materials with buffering properties, which can effectively buffer the impact when the test tube is placed, and solve the problems of test tubes easily shaking and leaking when subjected to external force and easily breaking due to impact during the placement process in traditional racks.
[0041] The inner frame 2 and the outer frame 1 are rotatably installed. When it is necessary to take out the test tube, the inner frame 2 can be rotated flexibly to reduce the risk of bumps caused by frequent handling of test tubes. At the same time, under the action of gravity, the problem of leakage caused by shaking of test tubes is avoided, and the safety of test tube placement and use is further guaranteed.
[0042] Example 2
[0043] To achieve the function of stable support from the outer frame and flexible rotation from the inner frame, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the outer frame 1 includes an outer support frame 11. The upper sides of the outer support frame 11 have holes and bearings 12 are embedded therein. The bottom of the outer support frame 11 has a mounting hole 13 and an anti-slip pad 14 is installed at the bottom of the outer support frame 11.
[0044] Specifically, the outer support frame 11 in the outer frame 1 has holes on the upper sides of both sides and inserts bearings 12. The bottom has mounting holes 13 and anti-slip pads 14 are installed at the bottom. This design realizes the functional basis of stable support and flexible connection of the outer frame 1.
[0045] The outer support frame 11 serves as the main structure of the outer frame 1 and is capable of supporting the inner frame 2 and the test tubes.
[0046] The embedded installation of bearing 12 provides the conditions for the rotational connection between inner support frame 21 and outer support frame 11;
[0047] Mounting hole 13 is specifically used for mounting and fixing anti-slip pad 14. Anti-slip pad 14 is made of soft rubber material and has diamond anti-slip texture on the bottom, which can significantly enhance the friction between the shelf and the placement surface and effectively prevent the shelf from shaking or shifting.
[0048] Furthermore, the bearing 12, in conjunction with the connecting shaft 22, is used to connect the inner support frame 21 and the outer support frame 11.
[0049] Specifically, the bearing 12 and the connecting shaft 22 cooperate with each other to connect the inner support frame 21 and the outer support frame 11, thereby realizing the rotation function of the inner frame 2 relative to the outer frame 1.
[0050] This connection method has good rotational flexibility and stability, which can effectively reduce frictional loss during rotation and ensure that the inner support frame 21 rotates smoothly around the bearing 12 under the action of the connecting shaft 22, making it convenient for operators to pick up test tubes.
[0051] Furthermore, the mounting hole 13 is used for the installation of the anti-slip pad 14, which is made of soft rubber material and has a diamond-shaped anti-slip texture on the bottom.
[0052] Specifically, the mounting holes 13 at the bottom of the outer support frame 11 are used for the installation of the anti-slip pad 14, thus achieving a stable connection between the anti-slip pad 14 and the outer frame 1.
[0053] The outer support frame 11 fixes the anti-slip pad 14 to the bottom through the mounting hole 13. The anti-slip pad 14 is made of soft rubber material. Its unique diamond anti-slip texture on the bottom increases the contact resistance with the table or other flat surfaces, and has excellent anti-slip effect. It can effectively prevent the shelf from being displaced due to external force during the experimental operation, thus ensuring experimental safety.
[0054] Example 3
[0055] To further improve the stability of the inner frame during rotation and the safety of test tube placement, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a counterweight rod 26 is fixedly installed on the bottom inner side of the inner support frame 21. The counterweight rod 26 is used to counterweight the inner support frame 21.
[0056] Specifically, a counterweight rod 26 is fixedly installed on the bottom inner side of the inner support frame 21, which realizes the adjustment and balance of the center of gravity of the inner support frame 21.
[0057] The counterweight 26 plays an important role in adjusting the center of gravity of the inner support frame 21. When the test tube is placed on the inner frame 2 or the inner support frame 21 and rotated, the counterweight 26 can effectively maintain the balance and stability of the inner support frame 21 by properly distributing the weight, preventing the inner frame 2 from tipping over due to the shift of the center of gravity, and improving the safety of the shelf.
[0058] Furthermore, the positioning sleeve 25 adopts a funnel-shaped structure design, the positioning sleeve 25 is made of soft rubber material, and the inner wall of the positioning sleeve 25 is provided with horizontal anti-slip texture.
[0059] Specifically, the positioning sleeve 25 adopts a funnel-shaped structure design, is made of soft rubber, and has horizontal anti-slip texture on the inner wall, which realizes precise positioning and stable fixation of the test tube.
[0060] The funnel-shaped positioning sleeve 25 has the function of guiding the test tube to be inserted quickly and accurately, which can help operators quickly place the test tube in the designated position; the soft rubber positioning sleeve 25 can provide cushioning protection when fixing the test tube, preventing the glass test tube from breaking due to rigid contact;
[0061] The horizontal anti-slip texture on the inner wall increases the friction between the positioning sleeve 25 and the outer wall of the test tube, further preventing the test tube from shaking or slipping during placement, and ensuring the stability and safety of the test tube placement.
[0062] When using this utility model, place the shelf on a stable experimental table and ensure that the anti-slip pad 14 at the bottom of the outer frame 1 is in close contact with the table surface. The friction provided by the diamond-shaped anti-slip texture prevents the shelf from shifting during operation.
[0063] Align the test tube with the pre-drilled hole 23 on the inner support frame 21, and slowly insert it along the pre-drilled hole 23. The test tube will pass through the pre-drilled hole 23 and the sleeve 24 in sequence, and finally be inserted into the positioning sleeve 25. The funnel-shaped structure of the positioning sleeve 25 will guide the test tube to be inserted accurately. Its soft rubber material and the horizontal anti-slip texture on the inner wall will fit tightly against the test tube, playing a role in positioning and fixing, while also cushioning the impact during placement.
[0064] If the shelf is subjected to external force, the counterweight rod 26 at the bottom of the inner side of the inner support frame 21 will maintain the balance and stability of the inner frame 2 during rotation, preventing it from tipping over. The stable structure of the outer frame 1, the anti-slip pad 14, and the positioning sleeve 25 can effectively reduce the shaking of the test tubes and prevent leakage and breakage.
[0065] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
