Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to an adaptive test tube rack. Background Art

[0002] During experiments, researchers often need to use a variety of different test tubes or centrifuge tubes. However, most commonly used test tube racks on the market can only accommodate a single type of test tube or centrifuge tube, forcing researchers to prepare multiple test tube racks of different sizes to meet their needs. This practice not only takes up a large amount of laboratory space, reducing space utilization, but also increases the complexity of experimental preparation.

[0003] Chinese patent CN 211886969 U discloses a new test tube rack that claims to accommodate different types of test tubes. However, this design still presents some problems in practical application. In particular, the design of its concave elastic member, while intended to secure the test tubes, may not be able to effectively secure all types of test tubes due to the large differences in diameters of different test tube models. If the elasticity of the concave elastic member is insufficient or excessive, the test tube may wobble or even fall in the test tube rack, which not only affects the accuracy of the experiment but also may damage the test tube and the sample inside. Utility Model Content

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes an adaptive test tube rack.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An adaptable test tube rack includes a base plate, a back plate provided on the base plate, a test tube socket connected to the back plate, the test tube socket including an outer shell and an inner shell, a hollow cavity formed between the outer shell and the inner shell, a plurality of mounting notches arranged in an annular array on the inner shell, and rubber protrusions installed in the mounting notches.

[0007] Furthermore, when a test tube is inserted into the inner shell, the test tube squeezes the rubber protrusion to cause elastic deformation, causing the rubber protrusion to move toward the outer shell.

[0008] Furthermore, a plurality of support rods are provided between the outer shell and the inner shell.

[0009] Furthermore, the back plate is provided with a plurality of back plate inserting blocks, and the test tube plug sleeve is provided with a back plate slot that matches the back plate inserting blocks.

[0010] Furthermore, a left plug block is provided on the left side of the test tube plug sleeve, and a right slot is provided on the right side of the test tube plug sleeve, and adjacent test tube plug sleeves are plugged together through the left plug block and the right slot.

[0011] Furthermore, a connecting block is provided at the bottom of the test tube socket, a control valve is installed on the connecting block, a positioning groove for accommodating the insertion of the connecting block is provided on the bottom plate, and a positioning through hole for accommodating the installation of the control valve is provided in the middle of the positioning groove.

[0012] Furthermore, a locking mechanism is provided on one side of the positioning groove, and the locking mechanism can limit the relative movement between the connecting block and the base plate.

[0013] Furthermore, the locking mechanism includes a flexible spring and a positioning pin. A mounting hole is provided on the side wall of the positioning groove. A positioning pin is slidably fitted in the mounting hole. A flexible spring is provided between the positioning pin and the bottom of the mounting hole. A positioning pin hole is provided on the side wall of the connecting block. When the connecting block is in the positioning groove, the flexible spring can enable the directional pin to be inserted into the positioning pin hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the design of the backplate plug and the test tube plug-in sleeve of the present invention not only ensures the overall stability of the test tube rack, but also makes it easy to access and store the test tubes. The hollow cavity design between the inner and outer shells of the test tube plug-in sleeve effectively isolates the influence of external temperature on the sample in the test tube, providing a strong guarantee for the accuracy of experimental results. The use of rubber protrusions and support rods not only increases the friction between the test tube and the plug-in sleeve, preventing the test tube from slipping, but also greatly enhances the structural strength of the test tube rack, enabling it to carry test tubes of more specifications and meet the diverse needs of users during experiments. The design of the locking mechanism further enhances the stability and safety of the test tube rack, effectively preventing the test tube plug-in sleeve from moving or falling off.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0021] like Figure 1-Figure 4 As shown, an adaptable test tube rack comprises a base plate 1, a back plate 2 mounted on the base plate, and a test tube socket 3 mounted on the back plate. The test tube socket 3 comprises an outer shell 31 and an inner shell 32, with a hollow cavity 33 formed between the outer and inner shells. The inner shell has a plurality of mounting notches arranged in an annular array, each of which is equipped with rubber protrusions 37. The rubber protrusions increase friction between the test tubes and the socket, preventing them from slipping. The elasticity of the rubber allows them to accommodate test tubes of varying diameters, enhancing the versatility and flexibility of the test tube rack.

[0022] In a more detailed solution, when a test tube 100 is inserted into the inner shell, the test tube squeezes the rubber protrusion to cause elastic deformation, causing the rubber protrusion to move toward the outer shell.

[0023] Furthermore, a plurality of support rods are provided between the outer shell and the inner shell, which can enhance the structural strength of the test tube connector, prevent deformation or damage thereof, and increase its service life.

[0024] In at least one embodiment, the back panel is provided with a plurality of back panel inserts 21, and the test tube connector is provided with back panel slots 35 that cooperate with the back panel inserts. This plug-in method allows the test tube connector to be firmly fixed to the back panel and is convenient for removal and replacement.

[0025] Furthermore, a left insert block 34 is provided on the left side of the test tube socket, and a right slot 36 is provided on the right side of the test tube socket. The left insert block and the right slot cooperate, and adjacent test tube sockets are plugged together through the left insert block and the right slot. This design allows multiple test tube sockets to be tightly connected together to form a whole, improving the stability and load-bearing capacity of the test tube rack.

[0026] In at least one embodiment, a connection block 38 is provided at the bottom of the test tube connector, on which a control valve 39 is mounted. In conjunction with this, a positioning slot 11 is provided on the bottom plate to accommodate the connection block, and a positioning through-hole 12 is provided in the middle of the positioning slot to accommodate the installation of the control valve. The provision of the control valve can conveniently control the airflow within the hollow cavity, thereby facilitating the replenishment or degassing of the hollow cavity.

[0027] Furthermore, a locking mechanism is provided on one side of the positioning groove, and the locking mechanism can limit the relative movement between the connecting block and the base plate.

[0028] The solution is refined. The locking mechanism includes a flexible spring 14 and a positioning pin 15. A mounting hole 13 is provided on the side wall of the positioning groove. A positioning pin is slidably fitted in the mounting hole. A flexible spring is provided between the positioning pin and the bottom of the mounting hole. A positioning pin hole 381 is provided on the side wall of the connecting block. When the connecting block is in the positioning groove, the flexible spring can enable the directional pin to be inserted into the positioning pin hole.

[0029] In operation, the test tube adapter is plugged into the back panel through the back panel slot 35 and the back panel plug block 21. Adjacent test tube adapters can be plugged into each other through the left plug block 34 and the right slot 36, thereby stably connecting together to form an integrated test tube rack structure.

[0030] The test tube 100 is inserted into the inner housing 32 of the test tube socket. When the test tube is inserted, it squeezes the rubber protrusion 37, causing it to elastically deform and move toward the outer housing 31. This design ensures that the test tube is firmly placed in the test tube socket and can accommodate test tubes of different diameters.

[0031] A control valve 39 is mounted on the connection block 38 at the bottom of the test tube connector. This control valve can be used to control certain operations within the hollow cavity 33, such as allowing or blocking airflow. Insert the connection block 38 into the positioning slot 11 on the base plate 1, ensuring that the control valve 39 is aligned with the positioning hole 12 so that the control valve can function properly. When the connection block 38 is inserted into the positioning slot 11, a locking mechanism on one side of the positioning slot comes into play. The flexible spring 14 in the locking mechanism pushes the positioning pin 15 into the positioning pin hole 381 on the side wall of the connection block, thereby limiting the relative movement between the connection block and the base plate and ensuring the stability of the test tube connector.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
