Description

Technical Field

[0001] This utility model relates to the field of medical equipment accessories technology, specifically to a test tube holder. Background Technology

[0002] In current clinical practice, test tubes are typically transferred using test tube racks. Increasing the number of test tube mounting positions per unit area of ​​the rack can improve its load-bearing capacity and test tube transport efficiency. However, setting more mounting positions within the limited area of ​​the test tube rack not only increases the complexity of the mold but also raises the manufacturing cost of the test tube rack.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a test tube holder to solve the technical problem of high manufacturing cost of high-density test tube holders in related technologies.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a test tube holder is provided, comprising: a holder body, a support frame provided on the holder body, and a placement hole provided on the support frame; a test tube holder for loading test tubes, the test tube holder being assembled in the placement hole and detachably connected to the placement hole; and a limiting device, comprising a limiting component disposed in the placement hole and a limiting hole corresponding to the limiting component disposed on the test tube holder, the limiting hole extending along the length direction of the test tube holder, and the limiting component being slidably connected to the limiting hole.

[0006] Furthermore, the support frame is provided with a support body corresponding to the placement hole. The support body extends along the length direction of the test tube holder. The support body is hollow and contains at least part of the test tube holder. A limiting component is formed on the inner wall of the support body.

[0007] Furthermore, the limiting component includes a first buckle, which is formed by extending from the inner wall of the support towards the test tube holder. The first buckle includes a first limiting surface and a second limiting surface. The first limiting surface can abut against the upper end surface of the limiting hole, and the second limiting surface can abut against the lower end surface of the limiting hole.

[0008] Furthermore, the test tube holder includes a cylindrical part for loading test tubes and a cylindrical top connected to the cylindrical part. A limiting hole is formed on the cylindrical part, and a boss is provided on the cylindrical top. The boss protrudes from the outer surface of the cylindrical part, and a positioning groove is opened on the support frame corresponding to the placement hole. The boss is fitted into the positioning groove.

[0009] Furthermore, the cylindrical body includes: a clearance window extending along the length of the test tube holder; an elastic support inclinedly disposed within the clearance window, the end of the elastic support extending toward the test tube, the end of the elastic support having an abutment portion that can abut against the outer wall of the test tube; wherein, the elastic support includes at least two, the at least two elastic supports being spaced apart around the axis of the cylindrical body, and the clearance window includes at least two, the two clearance windows being disposed one-to-one with the elastic supports.

[0010] Furthermore, the test tube holder includes a mounting groove formed on the outer surface of the holder body, the mounting groove extending along the height direction of the holder body, the mounting groove being used to accommodate a positioning rod of an external device for positioning the test tube holder.

[0011] Furthermore, the mounting slots include multiple slots, with at least one mounting slot formed on a first side of the bracket body and at least two mounting slots formed on a second side opposite to the first side, wherein the number of mounting slots on the first side is different from the number of mounting slots on the second side.

[0012] Furthermore, the main body of the bracket is hollow, and the interior of the main body of the bracket contains at least part of the test tube holder.

[0013] Furthermore, the test tube holder includes a stop block, which protrudes from the support frame and extends along the height direction of the holder body. The shape of the stop block is adapted to the shape of the inner wall of the holder body. There are multiple stop blocks, which are spaced apart circumferentially along the holder body.

[0014] Furthermore, there are multiple placement holes arranged in a rectangular array on the main body of the bracket, and multiple test tube holders are provided with corresponding placement holes.

[0015] Beneficial effects:

[0016] 1. The test tube holder adopts a split structure. After the test tube holders are molded in batches, they are assembled with the main body of the holder, thus forming a test tube holder with high-density test tube mounting positions. This increases the test tube load per unit area, reduces the complexity of the high-density test tube holder mold, and reduces the mold opening cost and manufacturing cost of the test tube holder. It solves the technical problem of high manufacturing cost of high-density test tube holders in related technologies.

[0017] 2. By setting a limiting device, on the one hand, the split test tube holder can be limited to prevent it from tilting or falling during use, such as when transferring the test tube holder or when taking test tubes out of the holder. This makes it easier to assemble or unassemble the test tube holder. On the other hand, the limiting component is slidably connected to the limiting hole, allowing the test tube holder to float up and down. When a test tube needs to be removed from the test tube holder, the holder can float up and down slightly. When the test tube is thick, has many barcodes on it causing high friction between the test tube holder and the test tube, or when the surrounding test tube holders are full and the available area for the test tube is small, the floating design can lift the test tube to a certain height with less force, thereby obtaining a larger gripping area for easier and smoother removal of the test tube. At the same time, during the lifting process of the floating section, the momentum of the test tube increases, thereby overcoming some of the friction and allowing the test tube to enter and exit the test tube holder more smoothly.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] According to an embodiment of this utility model, a test tube holder is provided. Please refer to [link / reference]. Figures 1 to 9 The device includes: a bracket body 10, on which a support frame 1 is provided, and a placement hole 11 is provided on the support frame 1; a test tube holder 2, which is used to hold test tubes, and is assembled in the placement hole 11, and is detachably connected to the placement hole 11; and a limiting device, which includes a limiting component 31 provided in the placement hole 11 and a limiting hole 32 corresponding to the limiting component 31 provided in the test tube holder 2, the limiting hole 32 extending along the length direction of the test tube holder 2, and the limiting component 31 slidingly connected to the limiting hole 32.

[0031] Understandably, the number and layout of test tube holders 2 can be flexibly increased or decreased as needed without redesigning the entire holder structure or mold, thus reducing manufacturing complexity and cost.

[0032] It is understandable that by adopting the split test tube holder in this embodiment, keeping the main body 10 of the holder unchanged, only the test tube holder 2 needs to be replaced to meet different test tube installation requirements, further reducing the cost and time of mold development.

[0033] In this way, the test tube holder adopts a split structure. After the test tube holders 2 are molded separately in large batches, they are assembled with the holder body 10, thereby forming a test tube holder with high-density test tube mounting positions. This reduces the complexity of the high-density test tube holder mold, and reduces the mold opening cost and manufacturing cost of the test tube holder, thus solving the technical problem of high manufacturing cost of high-density test tube holders in related technologies.

[0034] In addition, by setting a limiting device, on the one hand, the split test tube holder 2 can be limited to prevent it from tilting or falling during the transfer of the test tube holder or when taking out or putting out test tubes in the test tube holder. This makes it easier to assemble or unassemble the test tube holder 2. On the other hand, when taking out a test tube, the test tube holder 2 can float up and down slightly. When the test tube itself is thick or has many barcodes on it, resulting in high friction between the test tube holder 2 and the test tube, or when the surrounding test tube holders 2 are full, resulting in a small area for taking out the test tube, the up and down floating design can lift the test tube to a certain height with less force, thereby obtaining a larger gripping area for easier and smoother removal of the test tube. At the same time, during the lifting process of the floating section, the momentum of the test tube increases, thereby overcoming some of the friction, allowing the test tube to enter and exit the test tube holder 2 more smoothly.

[0035] In practical use, various identification labels are often attached to test tubes, which increases the diameter of the test tubes and the surface friction. This makes the test tubes easier to remove and increases the convenience of test tube transportation.

[0036] In the test tube holder of this embodiment, see Figure 3 The support frame 1 is provided with a support body 12 corresponding to the placement hole 11. The support body 12 extends along the length direction of the test tube holder 2. The support body 12 is hollow and houses at least part of the test tube holder 2. A limiting component 31 is formed on the inner wall of the support body 12. In this way, the support body 12 extends along the length direction of the test tube holder 2 to support the test tube holder 2, preventing the test tube holder 2 from accidentally falling off or shifting during use. The test tube holder 2 can be directly inserted into or removed from the support body 12, making the operation simple and quick. In addition, by setting the limiting component 31, the test tube holder 2 can be positioned during the assembly process, allowing the support body 12 to quickly complete the positioning and assembly, further simplifying the assembly process.

[0037] Preferably, the support 12 is a cylindrical structure, located below the support frame 1, and perpendicular to the support frame 1.

[0038] In addition, the hollow support body 12 not only saves space, but also makes the entire test tube holder structure more compact and efficient, and reduces the overall weight of the holder body 10.

[0039] In the test tube holder of this embodiment, see Figure 3 and Figure 9The limiting component 31 includes a first buckle, which extends from the inner wall of the support body 12 toward the test tube holder 2. The first buckle includes a first limiting surface 311 and a second limiting surface 312. The first limiting surface 311 can abut against the upper end surface of the limiting hole 32, and the second limiting surface 312 can abut against the lower end surface of the limiting hole 32. In this way, during the up-and-down movement of the test tube holder, an upper limit and a lower limit can be formed on the test tube holder 2, respectively, preventing the test tube holder 2 from falling out of the placement hole 11.

[0040] Specifically, the first limiting surface 311 is located above the second limiting surface 312. The first limiting surface 311 is an inclined surface, which facilitates the first buckle to enter the limiting hole 32. The second limiting surface 312 is a plane to increase the limiting effect and further prevent the test tube holder 2 from falling out.

[0041] In some embodiments, the first buckle is located at the bottom of the support body 12, and the second limiting surface 312 is flush with the bottom surface of the support body 12, so as to facilitate the removal of the test tube holder 2 from the support body 12.

[0042] In some embodiments, see Figure 4 The test tube holder 2 is provided with a guide groove. The extension direction of the guide groove is collinear with the extension direction of the limiting hole 32. The guide groove is located below the limiting hole 32, so that it cooperates with the limiting component 31 during the assembly process of the test tube holder 2 to guide the movement direction of the test tube holder 2 and enable the test tube holder 2 to complete the assembly smoothly.

[0043] Preferably, a single test tube holder 2 is provided with two limiting holes 32, which are arranged opposite to each other, and a single support body 12 is provided with two first buckles, which are respectively arranged corresponding to the two limiting holes 32.

[0044] In the test tube holder of this embodiment, see Figure 4 The test tube holder 2 includes a cylindrical body 21 for loading test tubes and a cylindrical top 22 connected to the cylindrical body 21. A limiting hole 32 is formed on the cylindrical body 21, and a boss 221 is provided on the cylindrical top 22, protruding from the outer surface of the cylindrical body 21. A positioning groove 14 is provided on the support frame 1 corresponding to the placement hole 11, and the boss 221 is fitted into the positioning groove 14. This fitting design of the boss 221 and the positioning groove 14 ensures the stability of the test tube holder 2 on the support frame 1. The design of the boss 221 and the positioning groove 14 allows the test tube holder 2 to be flexibly inserted and removed, facilitating the assembly and removal of the test tube holder 2 and simplifying the installation and disassembly process.

[0045] In some embodiments, a first anti-rotation surface is provided at the edge of the boss 221, the first anti-rotation surface is perpendicular to the support frame 1, and a second anti-rotation surface is provided on the positioning groove 14 corresponding to the first anti-rotation surface. The first anti-rotation surface and the second anti-rotation surface fit together, which can further prevent the test tube holder 2 from rotating during use, thereby increasing the stability of the test tube holder 2.

[0046] It should be noted that the number of the first anti-rotation surface and the second anti-rotation surface can be one or more. Preferably, the number of the first anti-rotation surface and the second anti-rotation surface is four.

[0047] In the test tube holder of this embodiment, see Figure 4-6 The cylindrical portion 21 includes: a clearance window 211 extending along the length of the test tube holder 2; an elastic support 212 inclinedly disposed within the clearance window 211, the end of the elastic support 212 extending toward the test tube, and the end of the elastic support 212 having an abutment portion 213 that can abut against the outer wall of the test tube; wherein, at least two elastic supports 212 are included, and the at least two elastic supports 212 are distributed at intervals around the axis of the cylindrical portion 21, and at least two clearance windows 211 are included, with each clearance window 211 corresponding to one of the elastic supports 212.

[0048] In some embodiments, the abutment portion 213 is a second latch.

[0049] Specifically, the elastic support 212 is inclinedly positioned within the clearance window 211, and its end has an abutment portion 213 that can form flexible contact with the outer wall of the test tube. Utilizing the elastic characteristics of the elastic support, it provides a uniform clamping or supporting force for the test tube, ensuring that the test tube is firmly fixed within the cylindrical part 21 and preventing loosening or tipping due to vibration or movement. Simultaneously, the flexible clamping of the elastic support 212 and the open design of the clearance window 211 allow users to easily insert or remove test tubes without additional tools or complex operating procedures, significantly improving work efficiency. Furthermore, because the elastic support 212 has a certain elastic deformation capability, its abutment portion 213 can automatically adjust the clamping force according to the diameter of the test tube, allowing the same test tube holder 2 to accommodate test tubes of various sizes without the need to change equipment or make additional adjustments, thus improving the versatility and flexibility of the equipment.

[0050] In some embodiments, the elastic support 212 includes four elastic supports 212 evenly distributed around the axis of the test tube holder 2, and the clearance window 211 includes four.

[0051] Understandably, at least two elastic supports 212 are spaced apart around the axis of the cylindrical body 21, forming a multi-point support structure. This symmetrical clamping method further enhances the stability of the test tube.

[0052] Understandably, the clearance window 211 extends along the length of the test tube holder 2, providing installation space for the elastic support 212 and reducing the amount of material used in the cylinder 21, thereby reducing the overall weight. Furthermore, the clearance window 211 facilitates user observation of the test tubes' condition, making operation and maintenance easier.

[0053] In the test tube holder of this embodiment, see Figure 1 The test tube holder includes a mounting groove 13 formed on the outer surface of the holder body 10. The mounting groove 13 extends along the height direction of the holder body 10 and is used to accommodate the positioning rod of an external device for positioning the test tube holder. This design of the mounting groove 13 allows the positioning rod of the external device to be accurately embedded within it, ensuring that the test tube holder can be precisely fixed in the predetermined position of the external device during use. This improves the positioning accuracy of the test tube holder itself and also ensures its coordination with other experimental equipment. It allows the test tube holder to be quickly and easily connected or disconnected from external equipment without complicated tools or steps, greatly simplifying the installation and disassembly process. Furthermore, through precise positioning and stable support, it reduces the possibility of shaking during use.

[0054] In the test tube holder of this embodiment, see Figure 1 The mounting slots 13 include multiple slots, with at least one mounting slot 13 formed on the first side 23 of the bracket body 10, and at least two mounting slots 13 formed on the second side 24 opposite to the first side 23. The number of mounting slots 13 on the first side 23 is different from the number of mounting slots 13 on the second side 24. This arrangement of different numbers of mounting slots 13 on the first side 23 and the second side 24 of the test tube holder 2 makes the mounting slots easier to identify and distinguish, reducing the possibility of misoperation and acting as a foolproof mechanism. Users can find the correct installation position more quickly, improving work efficiency.

[0055] In some embodiments, mounting slots 13 may also be provided on the sides other than the first side 23 and the second side 24, as needed.

[0056] In some embodiments, the support frame 1 is provided with arrows arranged in a certain direction, the direction of the arrows corresponding to the arrangement pattern of the mounting slots 13. For example, a mounting slot 13 is opened on the first side 23, and two mounting slots 13 are opened on the second side 24, and the arrows point to the first side 23, thus forming a double directional pointing effect, which makes it convenient for users to transfer and install the test tube holder.

[0057] In the test tube holder of this embodiment, see Figure 3The main body 10 of the test tube holder is hollow inside, and at least part of the test tube holder 2 is accommodated inside the main body 10. In this way, the overall weight of the test tube holder is reduced, and the manufacturing cost of the test tube holder is lowered.

[0058] In the test tube holder of this embodiment, see Figure 1 The test tube holder includes a stop block 4, which protrudes from the support frame 1 and extends along the height of the holder body 10. The shape of the stop block 4 is adapted to the shape of the inner wall of the holder body 10. Multiple stop blocks 4 are spaced apart circumferentially along the holder body 10. When multiple test tube holders are stacked, a tight fit between the stop block 4 and the upper holder body 10 is ensured, effectively limiting the movement of the upper test tube holder and preventing it from shifting or tipping due to vibration or external force. This increases the stability of the stacked test tube holders and optimizes space utilization.

[0059] Preferably, the stop block 4 includes four blocks, which are respectively disposed at the four corners of the bracket body 10. The four stop blocks 4 are all arc-shaped or L-shaped, corresponding to the shape of the corners of the bracket body 10.

[0060] In the test tube holder of this embodiment, see Figure 1 The device includes multiple placement holes 11 arranged in a rectangular array on the main body 10 of the holder. Multiple test tube holders 2 are also arranged corresponding to multiple placement holes 11, with each holder corresponding to one of the holes 11. This rectangular array of placement holes 11 maximizes the use of space on the test tube holder, allowing for more efficient accommodation of more test tube holders 2, thus increasing the test tube capacity per unit area.
