Description

Technical Field

[0001] The invention relates to the technical field of test tube racks, in particular to a transparent rotating test tube rack capable of adjusting light intensity. Background Art

[0002] A test tube rack is a common laboratory device used to support and secure test tubes for various experimental procedures. In SOD enzyme experiments, a test tube rack is required to support and secure the test tubes. The rack is then placed in a light incubator, allowing light to illuminate the test tubes, triggering a reaction within the tubes.

[0003] However, the light lamps in the light incubator are usually set at a corresponding position and left stationary, which can easily lead to the test tubes close to the light lamps receiving more light intensity, while the test tubes far from the light lamps receiving less light intensity, which in turn leads to inconsistent light intensity received by the test tubes on the test tube rack, thus causing experimental errors.

[0004] Therefore, a transparent rotating test tube rack with adjustable light intensity is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a transparent rotating test tube rack with adjustable light intensity in order to solve the above problems, thereby improving the problem that the test tubes on the test tube rack receive inconsistent light intensity in the light incubator.

[0006] The present invention achieves the above-mentioned object through the following technical solutions: a transparent rotating test tube rack with adjustable light intensity, comprising: an illumination incubator, the front end of which is hinged with a cabinet door; a driving mechanism, the driving mechanism comprising a servo motor disposed inside the illumination incubator, the output shaft of the servo motor being fixedly connected to a first gear, the surface of the first gear being meshedly connected to a second gear, the top end of the second gear being fixedly connected to a mounting tube, the inner wall of the mounting tube being slidably connected to a positioning frame, the end of the positioning frame being fixedly connected to a movable sleeve, and the bottom end of the movable sleeve being fixedly connected to a cushion. The mounting tube, positioning frame, movable sleeve, and cushion are used to flexibly press and limit the transparent test tubes and seal the ports of the transparent test tubes, thereby preventing the liquid inside the transparent test tubes from shaking out during rotation. The servo motor, the first gear, and the second gear are used to enable the mounting tube, positioning frame, and transparent test tube rack to slowly rotate within the illumination incubator, thereby uniformly illuminating the test tubes on the test tube rack with light within the illumination incubator, ensuring the accuracy of the experiment.

[0007] Preferably, a lever is slidably connected to the lower end of the inner wall of the positioning frame, the surface of which is engaged with the inner wall of the mounting tube, and a spring is fixedly connected to the end of the lever, the other end of which is fixedly connected to the lower end of the surface of the positioning frame. The spring and the lever lock the positioning frame within the mounting tube, ensuring stable compression of the transparent test tube, thereby ensuring that the transparent test tube rack is stably mounted at the top end of the mounting tube.

[0008] Preferably, a limiting block is fixedly connected to the lower end of the surface of the cabinet door.

[0009] Preferably, a connecting ring is fixedly connected to the lower end of the surface of the positioning frame. The cabinet door is ensured to stably close the front end of the light incubator through the limit block and the cabinet door, so that the bottom end of the limit block stably contacts the end of the connecting ring, thereby ensuring that the positioning frame stably contacts the top end of the transparent test tube, thereby stably blocking the end of the transparent test tube.

[0010] Preferably, a mounting seat is fixedly connected to the inner bottom wall of the light incubator, and the lower end of the surface of the mounting tube is slidably connected to the inner wall of the mounting seat.

[0011] Preferably, the top end of the mounting tube is fixedly connected with an annular placement rod, which can be used to center the placement position of the test tube rack and ensure that the cushion can fully contact the test tube port on the test tube rack.

[0012] Preferably, the top end of the mounting seat is fixedly connected to a mounting frame, and the surface of the servo motor is fixedly connected to the inner wall of the mounting frame.

[0013] The beneficial effects of the present invention are:

[0014] 1. By installing the cylinder, positioning frame, movable sleeve and soft cushion, the transparent test tube is flexibly pressed and limited, and the port of the transparent test tube is blocked to prevent the liquid inside the transparent test tube from shaking out during rotation. The servo motor, first gear and second gear are used to achieve the slow rotation of the installation cylinder, positioning frame and transparent test tube rack in the light incubator. Compared with the existing light incubator that provides inconsistent light intensity to the test tubes on the test tube rack, this method rotates the test tube rack in the light incubator, so that the light intensity inside the test tube rack is consistent with the light intensity of the test tubes on the test tube rack, ensuring the accuracy of the experiment;

[0015] 2. The positioning frame is locked in the installation tube through the spring and the push rod. The cabinet door is stably closed to the front end of the light incubator through the limit block and the cabinet door. The bottom end of the limit block is stably in contact with the end of the connecting ring, ensuring stable compression of the transparent test tube, thereby ensuring that the transparent test tube rack is stably installed at the top of the installation tube.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, a transparent rotating test tube rack with adjustable light intensity includes: an illumination incubator 1, a cabinet door 2 is hinged at the front end of the illumination incubator 1; a driving mechanism 3, the driving mechanism 3 includes a servo motor 31 arranged inside the illumination incubator 1, the output shaft of the servo motor 31 is fixedly connected to a first gear 32, the surface of the first gear 32 is meshedly connected to a second gear 33, the top end of the second gear 33 is fixedly connected to a mounting cylinder 34, the inner wall of the mounting cylinder 34 is slidably connected to a positioning frame 35, the end of the positioning frame 35 is fixedly connected to a movable sleeve 36, and the bottom end of the movable sleeve 36 is fixedly connected to a soft pad 37.

[0023] The positioning frame 35 is made of polycarbonate, while the movable cover 36 and cushion 37 are both made of transparent silicone. A first magnetic strip is embedded in the front of the illuminated incubator 1, and a second magnetic strip is embedded in one side of the cabinet door 2. The first and second magnetic strips attract each other due to their opposite polarities. Lights are installed on both sides of the inner wall of the illuminated incubator 1, and a control panel is located on the upper surface of the illuminated incubator 1. The light intensity of the lights can be adjusted by manually adjusting the corresponding data on the control panel.

[0024] When SOD enzyme experiment is needed, the sample containing SOD enzyme is placed in a transparent test tube and the sample is mixed with the corresponding substrate, and then the reaction buffer is added. A plurality of transparent test tubes containing sample reagents are placed on the transparent test tube rack, and the cabinet door 2 is opened to place the transparent test tube rack on the top of the installation cylinder 34. The positioning frame 35 is pulled down, and the positioning frame 35 moves down to drive the movable sleeve 36 and the soft pad 37 to move down, so that the soft pad 37 flexibly contacts the port of the transparent test tube and blocks the port. At this time, the cabinet door 2 is pushed to close the front end of the light incubator 1, and the control panel on the light incubator 1 is operated. The board is used to adjust the light intensity of the lighting lamp on the transparent test tube and the servo motor 31 is turned on. The output shaft of the servo motor 31 rotates to drive the first gear 32 to rotate. Since the diameter of the first gear 32 is smaller than the diameter of the second gear 33, the specific gear diameter ratio can be selected according to actual needs. The rotation of the first gear 32 drives the second gear 33 to rotate slowly. The slow rotation of the second gear 33 drives the mounting cylinder 34, the positioning frame 35 and the transparent test tube rack to rotate slowly, so that the test tubes on the transparent test tube rack in the light incubator 1 are illuminated with the same light intensity. At this time, the activity change of the SOD enzyme under the light conditions is observed.

[0025] like Figure 3 As shown, the lower end of the inner wall of the positioning frame 35 is slidably connected to a push rod 38, the surface of the push rod 38 is clamped on the inner wall of the mounting tube 34, the end of the push rod 38 is fixedly connected to a spring 39, the other end of the spring 39 is fixedly connected to the lower end of the surface of the positioning frame 35, the lower end of the surface of the cabinet door 2 is fixedly connected to a limiting block 312, the lower end of the surface of the positioning frame 35 is fixedly connected to a connecting ring 311, and the top of the mounting tube 34 is fixedly connected to a ring-distributed placement rod 310.

[0026] Push the positioning frame 35 down to the appropriate position, and the elastic force of the spring 39 pushes the push rod 38 to move in the positioning frame 35, so that the push rod 38 is clamped in the installation tube 34. At this time, push the cabinet door 2 so that the bottom end of the limit block 312 contacts the top end of the connecting ring 311, so that the positioning frame 35 is stably installed in the installation tube 34.

[0027] like Figure 3 As shown, the bottom wall of the light incubator 1 is fixedly connected to a mounting seat 313, the lower end of the surface of the mounting tube 34 is slidably connected to the inner wall of the mounting seat 313, the top of the mounting seat 313 is fixedly connected to a mounting frame 314, and the surface of the servo motor 31 is fixedly connected to the inner wall of the mounting frame 314.

[0028] The cam 35 is then pulled down to lock the cam 36 and the cam 37. The cam 35 is then pulled down to lock the cam 36 and the cam 37. The cam 35 is then pulled down to lock the cam 36 and the cam 37.

[0029] It should be noted that the illumination incubator 1, the first magnetic strip, the second magnetic strip, the lighting lamp, the control panel and the servo motor 31 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the illumination incubator 1 and the servo motor 31 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
