Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, specifically a highly compatible test tube rack. Background Technology

[0002] Biological laboratory equipment uses various test tubes, which are usually placed on test tube racks. Test tubes come in a variety of sizes, and even test tubes of the same size can have different dimensions. The current practice is to make test tube racks according to the size of the test tubes used, which results in a variety of test tube racks. Users then have to choose the appropriate rack according to their needs, which is very inconvenient.

[0003] In addition, gaps exist between test tubes and test tube racks. In some experimental scenarios, it is necessary for experimental equipment to contact test tubes, or even apply pressure (such as positive pressure filtration). When the equipment attempts to remove the test tubes, it may cause the test tubes to stick together and be lifted up, resulting in an accident. Due to the existence of gaps, the position of test tubes in the test tube rack is also inaccurate, and the equipment may collide with the test tubes, causing an accident.

[0004] Therefore, a highly compatible test tube rack is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a highly compatible test tube rack that can solve the problem of inaccurate positioning of test tubes in the rack, which could lead to accidents caused by equipment colliding with the test tubes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly compatible test tube rack, comprising a rack body, wherein at least two cylindrical placement slots are provided on the top of the rack body along the horizontal length direction of the rack body, and the placement slots penetrate the bottom of the rack body;

[0007] A first ring-shaped spring is provided at the bottom of the placement groove. The first spring is attached to the inner wall of the placement groove, and several second springs are installed at intervals along the upper inner wall of the first spring. The second springs are strip-shaped and their tops are inclined towards the axis of the first spring.

[0008] A third spring is connected to the top of the second spring via an arc-shaped fourth spring. The third spring is strip-shaped and its top is tilted away from the axis of the first spring.

[0009] Preferably, the surfaces of the second spring, the third spring, and the fourth spring are all smooth surfaces.

[0010] Preferably, a strip groove is provided on the side of the first spring piece, and the strip groove extends through the first spring piece.

[0011] Preferably, an annular limiting groove is provided along the bottom edge of the placement groove, and the limiting groove corresponds to the top of the first spring piece.

[0012] Preferably, a base is provided at the bottom of the frame, and several grooves are provided on the top of the base, with each groove corresponding to a placement slot.

[0013] Preferably, at least two spaced screw holes are provided at the bottom of the frame, and through holes corresponding to the screw holes are provided on the base, so that the base and the frame can be detachably fixed by bolts.

[0014] Preferably, the frame is a hollow shell, and arc-shaped cut surfaces are provided on all edges of the frame.

[0015] Compared with the prior art, this utility model provides a test tube rack with strong compatibility and has the following beneficial effects:

[0016] 1. This utility model, through the combination structure of the first spring, the second spring, the third spring and the fourth spring, can adapt to test tubes of different sizes; the elastic deformation design of the springs ensures that the test tubes are firmly clamped when inserted, and at the same time achieves concentric positioning, solving the problem of frequent replacement of traditional test tube racks due to the variety of test tube specifications.

[0017] 2. This utility model can prevent the test tube from being accidentally pulled out of the experimental equipment by the clamping force applied to the test tube by the spring sheet, thus avoiding accidents caused by the loosening or falling off of the test tube.

[0018] 3. This utility model ensures the stability of the spring piece installation by using the limiting groove at the bottom of the placement slot and the strip groove of the first spring piece, further enhancing the fixing effect of the test tube. Attached Figure Description

[0025] 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.

[0026] Example:

[0027] Please see Figure 1 - Figure 5 This embodiment provides a highly compatible test tube rack, comprising a rack body 1. At least two cylindrical placement slots 2 are formed on the top of the rack body 1 along its horizontal length. The placement slots 2 extend through the bottom of the rack body 1, and each slot 2 is used for test tubes (e.g.,...). Figure 1 The test tubes are placed one by one at the location indicated by the middle arrow A. The setting of at least two placement slots 2 also provides multiple sets of simultaneous operations for placing multiple test tubes at the same time and detecting the experimental objects in the test tubes.

[0028] The frame 1 is a hollow shell, and arc-shaped cut surfaces are provided on the edges of the frame 1 to make the edges of the frame 1 no longer sharp, so as to prevent the experimental personnel from being scratched by the edges or corners of the frame 1 when handling the frame 1.

[0029] like Figure 1 and Figure 5 As shown, a first annular spring piece 5 is provided at the bottom of the placement groove 2. The first spring piece 5 is attached to the inner wall of the placement groove 2. In use, the first spring piece 5 is inserted into the placement groove 2 from the bottom. In order to make the first spring piece 5 stable in the placement groove 2, an annular limiting groove 10 is provided along the bottom edge of the placement groove 2. The limiting groove 10 corresponds to the top of the first spring piece 5 and limits the position of the first spring piece 5 in the placement groove 2 to ensure that the first spring piece 5 will not accidentally slide in the placement groove 2.

[0030] Furthermore, to ensure that the first spring piece 5 can fully fit against the inner wall of the limiting groove 10 during installation, a strip groove 9 is provided on the side of the first spring piece 5. The strip groove 9 extends through the first spring piece 5, meaning that during the production of the first spring piece 5, its own diameter can be greater than the diameter of the limiting groove 10. Combined with the elasticity of the first spring piece 5, when the first spring piece 5 is placed in the limiting groove 10, the strip groove 9 allows the first spring piece 5 to bend and compress regularly from its end, thus placing the first spring piece 5 into the limiting groove 10. This also improves the ease of installation of the first spring piece 5. Subsequently, the first spring piece 5 can be released, at which point the first spring piece 5 will unfold outward under its own elasticity, thereby fully fitting against the inner wall of the limiting groove 10.

[0031] like Figure 1 and Figure 5 As shown, several second springs 6 are installed along the upper inner wall of the first spring 5 at intervals. The second springs 6 are strip-shaped and their tops are inclined towards the axis of the first spring 5.

[0032] A third spring 7 is connected to the top of the second spring 6 via an arc-shaped fourth spring 8. The third spring 7 is strip-shaped and its top is inclined away from the axis of the first spring 5. That is, multiple L-shaped thin sheets with arc-shaped bends are formed along the edge of the first spring 5 in the placement groove 2. The wide-mouth design at the top also facilitates the insertion of the test tube between the spring sheets. In actual use, the maximum distance between the fourth spring sheets in the same placement groove 2 is less than the diameter of the test tube. That is, when the test tube is placed between the spring sheets, the end of the second spring 6 away from the fourth spring 8 and the end of the third spring 7 away from the fourth spring 8 will contact the inner wall of the placement groove 2. Under the limitation of the inner wall of the placement groove 2, the second spring 6, the third spring 7 and the fourth spring 8 are deformed by the compression of the outer wall of the test tube, thereby applying a reverse elastic force to the test tube, so that the test tube placed between the spring sheets is secured.

[0033] Specifically, the elastic action of the spring can accommodate test tubes of various sizes. The simultaneous action of multiple springs of the same specification can not only hold the test tube tightly, but also achieve concentric positioning of the test tube in the placement slot. Furthermore, the spring has a certain clamping force on the test tube, which can prevent the test tube from being pulled out during equipment operation.

[0034] Furthermore, the surfaces of the second spring 6, the third spring 7, and the fourth spring 8 are all smooth, reducing the frictional resistance when the test tube is inserted between the springs, allowing the test tube to be inserted into the springs more easily.

[0035] It should be noted that, as Figure 3 and Figure 4 As shown, a base 3 is provided at the bottom of the frame 1, and several grooves 4 are provided on the top of the base 3. The grooves 4 correspond one-to-one with the placement slots 2. After the test tube is inserted between the spring pieces, the top of the test tube will be placed in the groove 4, thereby supporting the test tube.

[0036] Furthermore, at least two spaced screw holes 12 are provided at the bottom of the frame 1, and through holes 11 corresponding to the screw holes 12 are provided on the base 3, so that the base 3 and the frame 1 can be detachably fixed by bolts, making it convenient to remove the spring and replace it. That is, when the spring is not elastic enough or damaged, it can be replaced to ensure that the test tube is well fixed in the placement slot 2.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
