Description

Technical Field

[0001] The utility model belongs to the technical field of use of test tube racks, in particular to a multi-specification sample transfer test tube rack. Background Art

[0002] A test tube rack is a type of chemical experimental instrument, mainly used to place and dry test tubes. Sometimes test tubes can also be placed on the test tube rack to observe the phenomena of an experiment. Some test tube racks also have an adjustable height function to accommodate test tubes of different sizes and the needs of different operators.

[0003] In the Chinese patent publication number CN220657630U, a test tube rack is mentioned, including a first supporting mechanism, a second supporting mechanism, a first frame body and a second frame body, the first end of the first frame body is rotatably engaged with the first supporting mechanism, the first end of the second frame body is rotatably engaged with the second supporting mechanism, the second end of the first frame body is hinged to the second end of the second frame body, and is used to slide with the bottom wall of the groove, so that the first cross bar moves in the first direction and the first vertical bar moves in the second direction. The first cross bar and the first vertical bar can adjust the size of the socket during the movement, so that the test tube rack can place test tubes of different diameters, thereby improving the flexibility of the test tube rack.

[0004] However, the size of the insertion hole can be adjusted by the first horizontal rod and the first vertical rod during the movement, which only adjusts the size of the test tube rack, but cannot adjust the height of the test tube rack. As a result, the height of the test tube rack cannot be changed during use, which limits the use of test tubes.

[0005] Therefore, those skilled in the art have proposed a multi-specification sample transfer test tube rack to solve the problems raised in the background art. Utility Model Content

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] Embodiment 1: The present invention provides a multi-specification sample transfer test tube rack, comprising a support plate 1, a universal wheel 2 being provided at the bottom of the support plate 1, a support frame 3 being provided at the top of the support plate 1, a connecting seat 5 being provided on the side wall of the support frame 3, and a limit frame 6 being provided at the top of the connecting seat 5;

[0027] The side wall of the support frame 3 is provided with an adjustment mechanism 4, and the adjustment mechanism 4 includes a fixed plate 401, and the side wall of the fixed plate 401 is provided with an arc rod 405, and the top of the arc rod 405 is provided with a movable seat 406, and the side wall of the movable seat 406 is provided with a support seat 402, and the side wall of the support seat 402 is provided with a handle 407, and a spring 404 is provided in the support seat 402, and the side wall of the support seat 402 is provided with a clamping seat 403.

[0028] Furthermore, there are two of the arc rods 405 and the movable seat 406, the two arc rods 405 are hinged on the side wall of the support seat 402, the movable seat 406 is rotatably connected to the side wall of the support seat 402, the handle 407 is fixed to the side wall of the support seat 402, and there are multiple springs 404 and clamping seats 403, the spring 404 is fixed to the inside of the support seat 402, and the clamping seat 403 is slidably connected to the inside of the support seat 402 through the spring 404.

[0029] Furthermore, a connecting rod 9 is provided inside the connecting seat 5 , and a sleeve 10 is provided inside the connecting rod 9 . The connecting seat 5 is rotatably connected to the inner wall of the supporting frame 3 through the connecting rod 9 .

[0030] Furthermore, a rotating plate 8 is provided on the side wall of the support frame 3 , and a movable rod 7 is provided on the side wall of the rotating plate 8 . The rotating plate 8 is slidably connected to the inside of the sleeve 10 , and the movable rod 7 is slidably connected to the inside of the rotating plate 8 .

[0031] Furthermore, the limiting frame 6 is rotatably connected to the inner wall of the connecting seat 5 , and the fixing plate 401 is hinged to the bottom of the connecting seat 5 .

[0032] Furthermore, a plurality of universal wheels 2 are provided, and the universal wheels 2 are rotatably connected to the bottom of the support plate 1 .

[0033] Furthermore, the present invention is designed and applied in a test tube rack primarily for storing, drying, and observing test tubes in the laboratory. During chemical experiments, the test tube rack conveniently supports the test tubes, allowing the experimenter to continue observing the reaction without interrupting the experiment. Simultaneously, the test tube rack keeps the test tubes neat and orderly, improving experimental efficiency and accuracy. The test tube rack has the characteristics of simple structure, ease of use, and good durability. Wooden and bamboo test tube racks are lightweight and portable, making them suitable for various laboratory environments.

[0034] As can be seen from the above, by placing the test tube on the top of the limiting frame 6, the limiting frame 6 fixes the test tube to prevent the test tube from being broken. When the test tube is large in size, the handle 407 is pulled to drive the support seat 402 to move, and the support seat 402 drives the arc rod 405 to move. It is worth noting that the side wall of the arc rod 405 is provided with a roller, so that the arc rod 405 and the roller move in the fixed plate 401, and at the same time the movable seat 406 on the side wall of the support seat 402 moves in the fixed plate 401. When the support seat 402 and the arc rod 405 move to one side of the fixed plate 401, the movable seat 406 contacts the inside of the fixed plate 401, and the bottom of the test tube contacts the top of the clamping seat 403, and the clamping seat 403 is pushed to move by the test tube. At the same time, the clamping seat 403 forms a compression effect on the spring 404, and the spring 404 acts in the reverse direction to push the clamping seat 403 to move. When the test tube is clamped in the support seat 402, the support seat 402 is pushed to move, so that the support seat 402 is moved on the arc rod. Under the action of 405, the support seat 402 drives the test tube into the interior of the support frame 3, achieving the clamping effect of the test tube and protecting the test tube. When the technician needs to use the test tube for a long time to conduct experiments, the rotating plate 8 is rotated to drive the sleeve 10 to rotate, and the sleeve 10 and the connecting rod 9 are connected by rotation. The sleeve 10 drives the connecting rod 9 to rotate, and the connecting rod 9 drives the connecting seat 5 to rotate. The hinge between the connecting seat 5 and the fixed seat 401 is used to make the connecting seat 5 drive the fixed seat 401 to rotate. When the fixed seat 401 is rotated to the appropriate position, it is necessary to pull the handle 407 to move the support seat 402 inside the fixed plate 401. At the same time, the support seat 402 moves to the appropriate position, and the side wall of the rotating plate 8 is pushed to contact the side wall of the support frame 3. The movable rod 7 is pushed to move the movable rod 7 inside the rotating plate 8. At the same time, one end of the movable rod 7 is embedded in the interior of the connecting seat 5. Through the cooperation of the movable rod 7 and the rotating plate 8, the position of the connecting seat 5 is fixed, thereby ensuring the convenience of technicians in using different test tubes.

[0035] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the limiting frame 6 is rotatably connected to the inner wall of the connecting seat 5 , and the fixing plate 401 is hinged to the bottom of the connecting seat 5 .

[0036] As can be seen from the above, by utilizing the fixed rotation connection between the limit frame 6 and the connecting seat 5, the limit frame 6 is rotated under the action of the connecting seat 5, so that the limit frame 6 and the connecting seat 5 are in a horizontal plane, ensuring the use of technicians.
