Description

Technical Field

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

[0002] In laboratory settings, test tube holders are commonly used to store and secure test tubes. These holders primarily consist of a base and a support plate. The support plate has through-holes that mate with the test tubes. When storing, the test tubes are inserted into these holes, allowing the bottom of the tube to contact the base for support, ensuring stable storage and preventing them from easily falling off. However, existing test tube holders have relatively fixed hole diameters and heights, lacking adjustability, resulting in poor applicability and inadequate securing effect. During movement or transportation, test tubes are easily detached or damaged by collisions.

[0003] The patent titled "A Test Tube Holder for a Laboratory" (publication number "CN215429192U") addresses the aforementioned problem. However, due to mechanical limitations, this device can only hold two rows of test tubes, resulting in a limited number of tubes that can be stored, thus affecting its effectiveness in storing larger quantities of test tubes. Therefore, this invention designs a test tube holder for a laboratory to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A preferred embodiment of the laboratory tube rack provided by this utility model is as follows: Figures 1 to 5As shown: A test tube rack for a laboratory includes a frame 1; positioning nets 2 fixed at the upper and lower ends inside the frame 1; mounting plates 3 fixed between each pair of positioning nets 2, with several mounting plates 3; and a linkage assembly 4 assembled inside the mounting plates 3, which can fix the position of the test tubes inside the positioning nets 2. The linkage assembly 4 includes a rotating rod 401 rotatably disposed inside the mounting plates 3, with the right side of the rotating rod 401 penetrating through the frame 1; and a top block 402 rotatably sleeved outside the rotating rod 401, with several top blocks 402. The mounting plates 3 and the positioning nets 2 are designed to be perpendicular to each other, and the width of the cross-section of the top block 402 is equal to the width of the cross-section of the mounting plate 3.

[0029] It should be noted that the existing test tube racks in the laboratory still have certain shortcomings in actual use. They can only fix the position of two rows of test tubes, and cannot fix the position of multiple rows of test tubes, which affects the effectiveness of the test tube racks in holding a large number of test tubes.

[0030] In this embodiment, the user first passes a number of test tubes through the positioning net 2 from top to bottom, so that the frame 1 supports the bottom of the test tubes and the positioning net 2 positions the test tubes placed inside the frame 1. The user then rotates the rotating rod 401 in sequence, which drives the top block 402 to rotate along the direction of the test tubes, thereby causing the top block 402 to exert a clamping force on the outer wall of the test tubes, thus fixing the position of the positioned test tubes.

[0031] In a further preferred embodiment of this utility model, a drive assembly 5 is disposed on the outer wall of the frame 1. The drive assembly 5 can control a plurality of rotating rods 401 to operate synchronously. The drive assembly 5 includes a mounting bracket 501 fixedly disposed on the right side of the outer side of the frame 1, the mounting bracket 501 being rotatably sleeved on the outside of the rotating rods 401; a worm 502 rotatably disposed inside the mounting bracket 501; and a worm wheel 503 fixedly sleeved on the right side of the outer side of the rotating rods 401. The worm wheel 503 and the worm 502 are designed to mesh with each other. The mounting bracket 501 has a U-shaped cross-section when viewed from above. The front end of the worm 502 passes through the mounting bracket 501, and the length of the worm 502 is greater than the length of the mounting bracket 501.

[0032] In this embodiment, the user can rotate the worm gear 502, which drives the worm wheel 503 and the rotating rod 401 to rotate, thereby enabling the worm gear 502 to simultaneously control multiple top blocks 402 to clamp multiple test tubes. In addition, the self-locking force of the worm gear 502 and the worm wheel 503 locks the test tubes in their fixed positions.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the laboratory tube rack provided by this utility model is as follows: Figures 1 to 5As shown: The mounting plate 3 has a number of clearance holes 6 integrated inside. The clearance holes 6 are through holes and correspond one-to-one with the top block 402. The mounting bracket 501 has a limit component inside. The limit component can lock the rotated worm gear 502. The limit component includes a pin 7 threaded inside the mounting bracket 501 and a number of insertion holes 8 integrated inside the worm gear 502. The insertion holes 8 are blind holes. The axis of the insertion hole 8 and the axis of the pin 7 are designed to be on the same plane. The pin 7 and the insertion hole 8 are connected by plugging and unplugging.

[0035] In this embodiment, the clearance hole 6 provides rotation space for the top block 402. After the clamping force of the top block 402 on the test tube meets the user's needs, the user screws the pin 7 into the insertion hole 8, thereby locking the state of the worm gear 502 after rotation, preventing the worm gear 502 from being accidentally touched, which would cause the clamping force of the top block 402 on the test tube to fail.

[0036] In a further preferred embodiment of this utility model, mounting pins 9 are fixedly inserted through the upper left and right sides of the frame 1. A handle 10 is rotatably sleeved on the outside of the mounting pin 9. The handle 10 has a U-shaped design. Guide holes 11 are integrally provided on the left and right sides inside the handle 10. The guide holes 11 are through holes. A shaped rod 13 is slidably provided inside the guide holes 11. A limiting hole 12 is integrally provided inside the mounting pin 9. The limiting hole 12 is through holes. The axis of the limiting hole 12 is parallel to the mounting plate 3. The limiting hole 12, the handle 10, and the frame 1 are misaligned. The limiting hole 12 and the shaped rod 13 are disassembled and assembled by plugging.

[0037] In this embodiment, when the user needs to transfer the test tube, first rotate the handle 10 so that the handle 10 is perpendicular to the positioning net 2, then hold the shaped rod 13 and the handle 10. The shaped rod 13 moves upward along the direction of the guide hole 11, that is, the shaped rod 13 is inserted into the limiting hole 12. The purpose is to lock the rotation state of the handle 10 and the mounting pin 9, to prevent the frame 1 from shaking when the handle 10 drives the frame 1 to transfer, and to ensure the stability of the test tube placed inside the frame 1.

[0038] In summary, this application can synchronously fix the positions of test tubes in multiple rows, thereby enabling the device to be used with a large number of test tubes. The locking function design can lock the state of the test tubes after clamping. In addition, the positioning function design can prevent the frame from shaking when the handle, frame and test tubes are transported, ensuring the stability of the test tubes placed inside the frame.
