[0026] In order to better understand the technical solutions provided by the embodiments of the present specification, the technical solutions of the embodiments of the present specification will be described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present specification and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification. In the case of no conflict, the technical features in the embodiments of the present specification and the embodiments can be combined with each other.

[0027] In this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that includes the recited element. The term "two or more" includes two or more than two.

[0028] At present, when carrying out medical experiments, it is usually necessary to prepare multiple reagents, the reagents are loaded in test tubes, and the test tubes are placed on a test tube rack through a test tube clamp. However, the test tube racks in medical laboratories are mostly rowed test tube racks. When it is necessary to temporarily store or take the test tubes, due to the long distance between the test tube rack and the experimental equipment, it is not convenient to take and place the test tubes.

[0029] To this end, the present application provides an adsorption type test tube clamp 100.

[0030] As Figure 1As shown, the adsorption type test tube clamp 100 according to the embodiment of the present application comprises a base 10 and a clamping assembly 20.

[0031] The clamping assembly 20 is connected with the base 10 and is used for clamping a test tube, such as Figure 2 and Figure 3 As shown, the base 10 is provided with an adsorption assembly 30, and the adsorption assembly 30 comprises a magnetic attraction piece 31 and a suction cup 32.

[0032] The magnetic attraction piece 31 is used for magnetic attraction cooperation with a metal surface of experimental equipment, and the suction cup 32 is used for vacuum adsorption with the metal surface of the experimental equipment.

[0033] It can be understood that the magnetic attraction piece 31 comprises but is not limited to a magnet or an electromagnet, and the metal surface of the experimental equipment is a metal material that can be magnetically attracted by the magnet or the electromagnet, so that when it is needed to fix the adsorption type test tube clamp 100 to the experimental equipment, the magnetic attraction piece 31 can be directly used to fix the base 10 to the metal surface of the experimental equipment, that is, to fix the adsorption type test tube clamp 100 to the experimental equipment.

[0034] The suction cup 32 can be a silica gel suction cup 32. When the suction cup 32 is squeezed, the air in the suction cup 32 is discharged, resulting in a decrease in the pressure inside the suction cup 32. Due to the existence of the external atmospheric pressure, the air pressure outside the suction cup 32 is much greater than the pressure inside the suction cup 32, which generates a strong adsorption force, so that the suction cup 32 is tightly adsorbed on the surface of an object. Therefore, the base 10 can be adsorbed on the metal surface of the experimental equipment by using the suction cup 32.

[0035] Therefore, when it is needed to temporarily place a test tube, the test tube can be clamped by the clamping assembly 20, and then the base 10 can be magnetically attracted to the metal surface of the experimental equipment by using the magnetic attraction piece 31, or the base 10 can be adsorbed on the surface of the experimental equipment by using the suction cup 32, or the base 10 can be fixed to the metal surface of the experimental equipment by simultaneously using the magnetic attraction piece 31 and the suction cup 32. In this way, when it is needed to temporarily store or take a test tube, the fixed position of the adsorption type test tube clamp 100 is not affected by the distance between the test tube rack and the experimental equipment, thereby facilitating the convenience of taking and placing a standby reagent in the experimental process.

[0036] It is worth noting that in the case of fixing the base 10 to the metal surface of the experimental equipment by simultaneously using the magnetic attraction piece 31 and the suction cup 32, the magnetic attraction piece 31 can play a certain positioning role, thereby avoiding the separation of the base 10 from the experimental equipment due to the operation error of squeezing the suction cup 32, or in the case that the magnetic adsorption cannot be realized on the surface of the experimental equipment, the suction cup 32 can be used alone to fix the base 10 to the experimental equipment, thereby facilitating the increase of the use scenarios of the adsorption type test tube clamp 100 and reducing the problem that the use scenarios of the adsorption type test tube clamp 100 are limited due to the material of the experimental equipment.

[0037] Further, one of the magnetic member 31 and the suction disc 32 is arranged around the other, for example, the suction disc 32 can be arranged on the side of the base 10 away from the clamping assembly 20, the magnetic member 31 can be sleeved on the base 10, or the suction disc 32 can be sleeved on the base 10, and the magnetic member 31 is arranged on the side of the base 10 away from the clamping assembly 20. In this way, the layout of the magnetic member 31 and the suction disc 32 is more reasonable, and interference between the two is avoided, thereby affecting the fixation of the suction type test tube clamp 100 and the experimental equipment.

[0038] When the magnetic member 31 is magnetically attracted to the metal surface of the experimental equipment, the end of the magnetic member 31 facing the metal surface of the experimental equipment and the end of the suction disc 32 facing the metal surface of the experimental equipment are located in the same plane parallel to the base 10. In this way, when the magnetic member 31 is magnetically attracted to the metal surface of the experimental equipment, the suction disc 32 can also be deformed to the extent of being adsorbed to the metal surface of the experimental equipment, thereby avoiding mutual influence between the two, and further enabling the magnetic member 31 to be adsorbed to the metal surface of the experimental equipment at the same time as the suction disc 32. In this way, the suction type test tube clamp 100 can be fixed on the experimental equipment, thereby improving the convenience of taking and placing the standby reagent during the experiment.

[0039] According to the suction type test tube clamp 100 of the embodiments of the present application, by arranging the adsorption assembly 30, the suction type test tube clamp 100 can be magnetically attracted to the metal surface of the experimental equipment by the magnetic member 31, or can be adsorbed to the metal surface of the experimental equipment by the suction disc 32, or can also be fixed to the metal surface of the experimental equipment by the magnetic member 31 and the suction disc 32 at the same time. In this way, the suction type test tube clamp 100 can be fixed on the experimental equipment, thereby improving the convenience of taking and placing the standby reagent during the experiment.

[0040] In some embodiments, as shown in FIG. 2, the suction disc 32 includes a bottom wall 321 and a side wall 322, the bottom wall 321 is connected with the base 10, the side wall 322 is connected with the bottom wall 321 and defines a cavity of the suction disc 32, and the magnetic member 31 is located in the cavity of the suction disc 32 and connected with the bottom wall 321. Figure 2 In this way, the arrangement of the magnetic member 31 can utilize the space in the cavity of the suction disc 32, thereby improving the space utilization rate, and at the same time, the magnetic member 31 is connected with the bottom wall 321, so that the arrangement of the magnetic member 31 will not interfere with the side wall 322 of the suction disc 32 when the side wall 322 is deformed, thereby ensuring the normal use of the suction disc 32.

[0041] In some embodiments, the magnetic member 31 is configured as a ring member.

[0042]

[0043] ​It can be understood that the sidewall 322 of the suction disc 32 is annular, and the magnetic member 31 is also annular, so that the magnetic member 31 can enhance the adsorption effect of the suction disc 32 on the metal surface of the experimental equipment in the circumferential direction of the suction disc 32 when the magnetic member 31 is adsorbed on the metal surface of the experimental equipment, thereby enhancing the connection stability of the adsorption type test tube clamp 100 and the experimental equipment.

[0044] In some embodiments, the plurality of magnetic members 31 are arranged around the center line of the bottom wall 321.

[0045] Therefore, the plurality of magnetic members 31 can realize the magnetic adsorption of the base 10 on the metal surface of the experimental equipment, and the arrangement of the plurality of magnetic members 31 can reduce the risk of failure of one of the magnetic members 31 to adsorb on the metal surface of the experimental equipment.

[0046] Meanwhile, the plurality of magnetic members 31 are arranged around the center line of the bottom wall 321, so that the magnetic member 31 can enhance the adsorption effect of the suction disc 32 on the metal surface of the experimental equipment in the circumferential direction of the suction disc 32 when the magnetic member 31 is adsorbed on the metal surface of the experimental equipment, thereby enhancing the connection stability of the adsorption type test tube clamp 100 and the experimental equipment.

[0047] In some embodiments, as shown in Figure 3 the magnetic member 31 is annular, the annular member is connected with the base 10 and defines an installation area 27 with the base 10, and the suction disc 32 is located in the installation area 27.

[0048] Therefore, the suction disc 32 can be located in the area radially inside the annular member, so that the layout of the suction disc 32 and the magnetic member 31 is more reasonable, and the difficulty of arranging the suction disc 32 is reduced, and the magnetic member 31 and the suction disc 32 are not interfered.

[0049] In some embodiments, the base 10 is provided with a mounting groove 11, and at least part of the magnetic member 31 is located in the mounting groove 11, so that the connection stability of the magnetic member 31 and the base 10 is enhanced, and the magnetic member 31 is arranged to be located in the same plane as the end of the suction disc 32 facing the metal surface of the experimental equipment when the magnetic member 31 is adsorbed on the metal surface of the experimental equipment.

[0050] In some embodiments, the clamping assembly 20 is rotatably connected with the base 10.

[0051] Therefore, the clamping assembly 20 can rotate relative to the base 10, so that the relative angle between the clamping assembly 20 and the base 10 is adjusted, so that the relative angle between the test tube and the base 10 is adjusted by the relative rotation between the clamping assembly 20 and the base 10 when the clamping assembly 20 clamps the test tube, thereby facilitating the taking and placing of reagents.

[0052] For example, the clamping assembly 20 can be rotatably connected with the base 10 through a connecting shaft, or the clamping assembly 20 can be hingedly connected with the base 10 to achieve rotatable connection of the two, and of course, the rotatable connection of the clamping assembly 20 and the base 10 can be achieved in other ways, which are not limited herein.

[0053] In some embodiments, as shown in Figure 1 The clamping assembly 20 includes a bottom plate 21 connected with the base 10 and two clamping arms 22 connected with opposite ends of the bottom plate 21 to define a clamping space 26 for clamping a test tube; and a resilient connecting piece 23 is arranged between the two clamping arms 22 to apply an elastic force for moving the two clamping arms 22 closer to each other.

[0054] It can be understood that the clamping space 26 is defined between the two clamping arms 22 and the bottom plate 21, and the resilient connecting piece 23 arranged between the two clamping arms 22 can apply an elastic force for moving the two clamping arms 22 closer to each other, so that the two clamping arms 22 have a tendency to move closer to each other, and thus the clamping of the test tube can be achieved by utilizing the tendency of the two clamping arms 22 to move closer to each other.

[0055] In some implementations, the resilient connecting piece 23 can be a spring, a torsion spring, or silica gel, which are not limited herein.

[0056] In some embodiments, as shown in Figure 1 An end of at least one clamping arm 22 away from the bottom plate 21 is provided with a rotating shaft 24, and a rotatable roller is sleeved on the rotating shaft 24 and adapted to abut against the test tube.

[0057] For example, an end of at least one clamping arm 22 away from the bottom plate 21 is provided with a rotating shaft 24, and a rotatable roller is sleeved on the rotating shaft 24 and adapted to abut against the test tube; or an end of each of the two clamping arms 22 away from the bottom plate 21 is provided with a rotating shaft 24, and a rotatable roller is sleeved on the rotating shaft 24 and adapted to abut against the test tube, which are not limited herein.

[0058] It can be understood that when the two clamping arms 22 clamp the test tube, the end of the clamping arm 22 away from the bottom plate 21 first contacts the test tube, at which time the test tube and the end of the clamping arm 22 away from the bottom plate 21 are in sliding friction, and the rotating shaft 24 is arranged at the end of the clamping arm 22 away from the bottom plate 21, and the rotatable roller is sleeved on the rotating shaft 24 and adapted to abut against the test tube, so that in the process of the test tube abutting against the roller and gradually moving to the clamping space 26 between the two clamping arms 22, the sliding friction between the test tube and the end of the clamping arm 22 away from the bottom plate 21 can be converted to rolling friction by the rotation of the roller relative to the rotating shaft 24, thereby reducing the friction and facilitating the clamping of the test tube by the clamping assembly 20.

[0059] Or in the process of the tube abutting against the roller and gradually moving away from the clamping arm 22 of the clamping space 26, the sliding friction between the tube and the end of the clamping arm 22 away from the bottom plate 21 can be converted into rolling friction by the rotation of the roller relative to the rotating shaft 24, so as to reduce the friction, and then facilitate the difficulty of clamping the tube by the clamping assembly 20.

[0060] In some embodiments, as shown in Figure 1 The outer peripheral wall of the roller is provided with elastic protrusions 25, and the plurality of elastic protrusions 25 are arranged around the axis of the rotating shaft 24.

[0061] Therefore, when the roller contacts the tube, the elastic protrusions 25 can be in flexible contact with the outer peripheral wall of the tube, so that rigid contact between the roller and the tube can be avoided, thereby facilitating the reduction of damage to the tube.

[0062] Meanwhile, the plurality of elastic protrusions 25 are arranged around the axis of the rotating shaft 24, so that at least one elastic protrusion 25 can be in flexible contact with the tube when the roller rotates around the rotating shaft 24, thereby avoiding rigid contact between the roller and the tube, and facilitating the reduction of damage to the tube.

[0063] In some embodiments, as shown in Figure 1 The elastic connecting piece 23 includes a silica gel strip, the silica gel strip is connected between the two clamping arms 22, and the side of the silica gel strip away from the bottom plate 21 and the two clamping arms 22 define the clamping space 26.

[0064] Therefore, the silica gel strip can exert an elastic force on the two clamping arms 22 to approach each other, so that the two clamping arms 22 can clamp the tube more stably. Meanwhile, the side of the silica gel strip away from the bottom plate 21 and the two clamping arms 22 define the clamping space 26, so that the clamping assembly 20 can clamp the tube by the two clamping arms 22 and the silica gel strip when clamping the tube. Since the silica gel strip has a certain flexibility, rigid contact between the tube and the bottom plate 21 can be avoided when clamping the tube, thereby facilitating the reduction of damage to the tube.

[0065] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0066] The above examples are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing examples, those ordinarily skilled in the art should understand: the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
