Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, and more specifically, to test tube racks used in hospital laboratories. Background Technology

[0002] Test tube racks are one of the most basic laboratory equipment in hospital laboratories. They are mainly used to support various test tubes (such as blood collection tubes, centrifuge tubes, reaction tubes, etc.), keep the test tubes upright, store different samples in categories, and facilitate batch operations and movement.

[0003] When hospital laboratories use test tube racks to store blood collection tubes, centrifuge tubes, reaction tubes, and other instruments, they need to select test tube racks with matching apertures based on the diameter of the test tubes. Different diameter test tubes require different test tube racks, which increases costs and makes the process of selecting test tube racks quite cumbersome. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a test tube rack for hospital laboratory departments, which aims to improve the stability and practicality of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution; A test tube rack for a hospital laboratory includes a base plate with two support plates fixedly connected to its top. A top plate is positioned above the base plate, and its bottom is fixedly connected to both support plates. The bottom of the top plate has two sets of equidistant recesses, each with a through hole in its inner wall. A cylinder is fixedly connected to the inner wall of each recess, and the cylinder has annularly distributed square grooves. A square rod is slidably connected to the inner wall of each groove. An adjusting plate is fixedly connected to one end of the square rod, and a spring is fixedly connected to the other end of the square rod. The other end of the spring is fixedly connected to the cylinder. A drive ring threadedly connected to the cylinder is fitted onto the cylinder, and an inclined surface is formed at the end of the square rod furthest from the cylinder.

[0006] As a further description of the above technical solution: A buffer block, which is an airbag layer, is fixedly connected to one side of the adjustment plate.

[0007] As a further description of the above technical solution: A buffer pad, which is a rubber layer, is fixedly connected to the top of the base plate.

[0008] As a further description of the above technical solution: The top plate has two sets of equally spaced annular cavities inside, the annular cavities being arranged in a ring shape and concentric with the through hole. The top plate also has a square cavity inside, the inner wall of which is rotatably connected to a lead screw. The top end of the lead screw passes through and extends to the top of the top plate. A piston plate is threaded onto the lead screw, and the outer side of the piston plate contacts the inner wall of the square cavity. The inner wall of the annular cavity is connected to annularly distributed flexible tubes, one end of which passes through the top plate and the adjusting plate and is connected to the buffer block. The inner wall of the square cavity is also connected to two sets of equally spaced conduits, one end of which passes through the top plate and is connected to the annular cavity.

[0009] As a further description of the above technical solution: Two square plates are fixedly connected to the top of the top plate, and each of the two square plates has a square hole.

[0010] Compared with existing technologies, the advantages of this utility model are: This solution can be used with test tubes of different diameters, thus effectively improving the practicality of the device. When carrying test tubes, they can be clamped to effectively prevent them from slipping off the test tube rack during transport, thereby improving the stability of the test tubes.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] To address the issue of non-adjustable test tube rack apertures, which necessitates time-consuming selection of racks with suitable apertures when placing test tubes of different diameters, and requires the preparation of multiple racks to accommodate various diameters, thus increasing costs, this solution provides Example 1: Please see Figures 1-6 In this utility model: a test tube rack for a hospital laboratory includes a base plate 1, with two support plates 2 fixedly connected to the top of the base plate 1. A top plate 3 is provided above the base plate 1, and the bottom of the top plate 3 is fixedly connected to the two support plates 2 respectively. Two sets of equally spaced recessed holes 4 are provided at the bottom of the top plate 3. Through holes 5 are provided on the inner wall of the recessed holes 4. A cylinder 6 is fixedly connected to the inner wall of the recessed holes 4. A square groove 7 distributed in annularly is provided on the cylinder 6. A square rod 8 is slidably connected to the inner wall of the square groove 7. An adjusting plate 9 is fixedly connected to one end of the square rod 8 located on the cylinder 6. A spring 10 is fixedly connected to the other end of the square rod 8. The other end of the spring 10 is fixedly connected to the cylinder 6. A drive ring 11 threadedly connected to the cylinder 6 is sleeved on the cylinder 6. An inclined surface 12 is provided at the end of the square rod 8 away from the cylinder 6.

[0015] In this invention, when in use, the test tube is inserted through the through hole 5, and the bottom end of the test tube passes through the cylinder 6 and contacts the base plate 1. At this time, multiple adjusting plates 9 will form an annular limiting ring. The test tube is located in the limiting ring and will be limited by the multiple adjusting plates 9, thereby realizing the placement of the test tube.

[0016] When placing test tubes of different diameters, the user rotates the drive ring 11, which rises along the cylinder 6. After rising, the cylinder 6 contacts the inclined surface 12 on the square rod 8. As the drive ring 11 presses against the inclined surface 12, the square rod 8 slides along the inner wall of the square groove 7 and compresses the spring 10. During the movement of the square rod 8, the adjusting plate 9 moves, and multiple adjusting plates 9 converge toward the center of the through hole 5, thereby achieving the effect of adjusting the diameter of the limiting ring hole. This allows it to be used for placing test tubes of different diameters.

[0017] Please see Figures 1-6 Among them, a buffer block 13 is fixedly connected to one side of the adjustment plate 9, and the buffer block 13 is an airbag layer.

[0018] In this invention, during the movement of the test tube rack, the test tubes are prone to collisions with the adjustment plate 9. After prolonged use, the adjustment plate 9 is prone to damage, which may also damage the test tubes. To avoid this problem, a buffer block 13 made of airbag is placed on the side of the adjustment plate 9 that contacts the test tubes. This buffering effect effectively extends the service life of the adjustment plate 9 and reduces the risk of damage to the test tubes.

[0019] Please see Figures 1-3 Among them, a buffer pad 14 is fixedly connected to the top of the base plate 1, and the buffer pad 14 is a rubber layer.

[0020] In this invention, the bottom of the test tube is in contact with the base plate 1, and the bottom of the test tube is prone to breakage. By setting the buffer pad 14, the bottom of the test tube can be cushioned, thereby effectively improving the stability of the test tube.

[0021] When transporting test tube racks and moving test tubes into the laboratory, if there is any bumpiness, the test tubes may easily slip out of the through hole 5, causing them to fall and break. To avoid this problem, this solution provides Embodiment Two: Please see Figures 1-6 The top plate 3 has two sets of equally spaced annular cavities 15 inside. The annular cavities 15 are arranged in a ring shape and are concentric with the through hole 5. The top plate 3 has a square cavity 16 inside. The inner wall of the square cavity 16 is rotatably connected to a lead screw 17. The top end of the lead screw 17 passes through and extends to the top of the top plate 3. A piston plate 18 is threadedly connected to the lead screw 17. The outer side of the piston plate 18 is in contact with the inner wall of the square cavity 16. The inner wall of the annular cavity 15 is connected to annularly distributed flexible hoses 19. One end of the flexible hoses 19 passes through the top plate 3 and the adjusting plate 9 in sequence and is connected to the buffer block 13. The inner wall of the square cavity 16 is connected to two sets of equally spaced conduits 22. One end of the conduits 22 passes through the top plate 3 and is connected to the annular cavity 15.

[0022] In this invention, after all the test tubes have been placed, the user rotates the lead screw 17. Since the lead screw 17 is threadedly connected to the piston plate 18, the rotation of the lead screw 17 will cause the piston plate 18 to descend along the inner wall of the square cavity 16. During this process, the piston plate 18 will squeeze the control in the square cavity 16 into each annular cavity 15 through the conduit 22. After the air enters the annular cavity 15, it will enter the buffer block 13 through the hose 19. The buffer block 13 will then expand. After the buffer block 13 expands, it will contact the outer wall of the test tube, thereby clamping the test tube. After the test tube is clamped, when the test tube rack is bumped, the test tube will not slip off the test tube rack, thereby improving the stability of the test tube placement.

[0023] Please see Figure 1 and 2 Among them, the top of the top plate 3 is fixedly connected to two square plates 20, and each of the two square plates 20 has a square hole 21.

[0024] In this invention, the square plate 20 and the square hole 21 can be combined to form a handle. The handle makes it convenient for users to carry the test tube rack, thereby improving the practicality of the device.

[0025] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
