Description

Technical Field

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

[0002] A test tube rack is an instrument used to hold test tubes and is widely used in hospitals and laboratories. Most existing clinical medical test tube racks have a simple structure, consisting of a base plate, two upright plates on both sides, and two partitions between the upright plates. The two partitions have multiple corresponding holes for placing test tubes.

[0003] However, the aforementioned traditional test tube racks have the following drawbacks: First, because test tubes may vary in size, with different outer diameters and heights, the tubes may not fit the size of the insertion holes or the height of the partitions when placed in the rack. This can cause the tubes to shake frequently within the insertion holes during transfer or use, potentially leading to collisions between tubes or between the tubes and the rack, resulting in breakage and damage to the samples or environmental contamination. This compromises the safe and stable use of the test tube rack. Second, existing test tube racks are typically large. When only one type or a small number of tubes need to be transferred, a large rack occupies significant space in transfer tools such as infusion trays, wastes manpower, and lacks flexibility.

[0004] In summary, a test tube rack that overcomes the above-mentioned problems needs to be designed. Utility Model Content

Test tube racks 5 are movably embedded in each placement area. One or more test tube racks 5 can be removed for individual use according to usage needs, or the entire support frame and test tube racks 5 can be used as a whole, making it more flexible to use.

[0044] The test tube rack 5 includes a base plate 51, a top plate 52, and a partition 53 slidably disposed between the base plate 51 and the top plate 52. A sliding control mechanism 54 is provided between the base plate 51 and the partition 53 to drive the partition 53 to move up and down. The sliding control mechanism 54 can adjust the distance between the partition 53 and the top plate 52, thereby satisfying the purpose of placing test tubes 7 of different heights. The upper surface of the top plate 52 is evenly provided with a plurality of through holes 521 along its length direction. The upper surface of the partition 53 is evenly provided with a plurality of hemispherical grooves 531 corresponding to the through holes 521. The test tubes 7 can be placed by inserting them into the through holes 521 and the hemispherical grooves 531 at the lower end of the through holes 521.

[0045] The inside of the through hole 521 is provided with symmetrical arc-shaped clamping plates 55 on the left and right sides respectively. The top plate 52 is provided with a clamping drive mechanism 56 that drives the two arc-shaped clamping plates 55 in each through hole 521 to move relative to each other or away from each other, so that the two arc-shaped clamping plates 55 in the same through hole 521 can effectively and stably clamp test tubes with different outer diameters.

[0046] Preferably, the upper surface of the base plate 51 is fixedly provided with sliding pillars 511 at the four corners, and the top ends of the four sliding pillars 511 are fixedly connected to the lower surface of the top plate 52. The four corners of the partition plate 53 are respectively provided with sliding holes 532 that are slidably connected to the sliding pillars 511. The partition plate 53 is slidably disposed on the sliding pillars 511 through the sliding holes 532.

[0047] Preferably, the sliding control mechanism 54 includes a first groove 541 formed in the middle of the upper surface of the base plate 51, a first slider 542 slidably disposed in the first groove 541, a first lead screw 543 rotatably disposed along the length of the first groove 541, and a connecting rod 544 whose two ends are respectively hinged to the upper end of the first slider 542 and the lower end of the partition plate 53. The front end of the first lead screw 543 extends out of the front side of the base plate 51 and is fixedly connected to a first handle 545. The first slider 542 is threadedly connected to the first lead screw 543. (Reference) Figure 3 As shown, turning the first handle 545 can drive the first lead screw 543 to rotate, and the first slider 542 on it can slide forward or backward, thereby raising or lowering the partition 53 through the connecting rod 544, and realizing the adjustment of the distance between the partition 53 and the top plate 52.

[0048] Preferably, the left and right sidewalls of the through hole 521 are respectively provided with arc-shaped grooves 522 for accommodating the arc-shaped clamping plate 55. A cylindrical groove 523 is provided in the middle of the side of the arc-shaped groove 522 away from the through hole 521. Movable cavities 524 communicating with multiple cylindrical grooves 523 on the same side are respectively provided inside the two sides of the top plate 52. Connecting columns 525 are slidably provided in each cylindrical groove 523. Fixing plates 526 are slidably provided in each movable cavity 524. The two ends of the connecting columns 525 are fixedly connected to the arc-shaped clamping plate 55 and the fixing plate 526 respectively. The front sides of the fixing plates 526 on both sides are respectively connected to the clamping drive mechanism 56. By setting a fixing plate 526, multiple connecting posts 525 and arc-shaped clamps 55 on the same side are connected, which facilitates the movement of multiple sets of arc-shaped clamps 55 in multiple through holes 521 towards or away from each other through the two fixing plates 526 on both sides. This allows the test tubes on the same test tube rack 5 to be fixed with a single operation, provided that test tubes 7 of the same specification are placed on the same test tube rack 5. Therefore, this test tube rack can classify and use test tubes of different specifications, making them easy to retrieve and easy to see.

[0049] Preferably, the clamping drive mechanism 56 includes a second slide groove 561 formed inside the front side of the top plate 52, second sliders 562 respectively slidably disposed on both sides inside the second slide groove 561, a second lead screw 563 rotatably disposed along the length direction of the second slide groove 561, and a first bevel gear 564 fixedly sleeved in the middle of the outer wall of the second lead screw 563. The second sliders 562 are respectively threaded to both sides of the second lead screw 563, and the thread directions on both sides of the second lead screw 563 are opposite. The second sliders 562 on both sides are respectively fixedly connected to the corresponding fixing plates 526.

[0050] The front sidewall of the second slide groove 561 also has a mounting cavity 527. A drive shaft 565 is rotatably mounted on the front sidewall of the mounting cavity 527. A second bevel gear 566, which meshes with the first bevel gear 564, is fixedly sleeved on the drive shaft 565. The front end of the drive shaft 565 extends out of the front sidewall of the top plate 52 and is fixedly connected to the second handle 567. (Reference) Figure 4 As shown, by turning the second handle 567, the drive shaft 565 can be rotated, which in turn drives the second lead screw 563 to rotate through gear transmission. Since the threads on both sides of the second lead screw 563 are opposite, the second sliders 562 on both sides can slide towards or away from each other, thereby enabling multiple sets of arc-shaped clamps 55 to move towards or away from each other, thus clamping or releasing the test tube 7.

[0051] Preferably, both the arc-shaped clamp 55 and the inner wall of the hemispherical groove 531 are provided with silicone pads 551 to prevent the test tube 7 from being damaged by direct contact with hard objects.

[0052] Preferably, the front side of the vertical partition 4 is located inside the upright plate 2, and a front baffle 6 is hinged to the upper front side of the base 1. The upper end of the front baffle 6 is connected to the upright plate 2 via a locking assembly 61. The upper and lower sides of the front baffle 6 are respectively provided with clearance slots 62. The clearance slots 62 facilitate the operation of the first handle 545 and the second handle 567 by medical personnel when the front baffle 6 is closed. The front baffle 6 effectively secures the test tube holder 5 embedded in the placement area, preventing it from slipping out. Furthermore, when the test tube holder 5 needs to be used independently, the front baffle 6 can be easily opened to retrieve the required test tube holder 5, making it more flexible, stable, and safer to use.

[0053] Preferably, the locking assembly 61 includes L-shaped round rods 611 movably disposed on the upper ends of both sides of the front baffle 6 and slots 612 respectively opened on the front side of the upper end of the upright plate 2. The upper ends of both sides of the front baffle 6 are respectively provided with convex grooves 613. One end of the L-shaped round rod 611 is movably disposed on one side inside the convex groove 613 via a protruding post 614. The L-shaped round rod 611 and the protruding post 614 can slide and rotate within the convex groove 613. The upper surface of the front baffle 6 also has clearance grooves 615 communicating with the convex grooves 613 on both sides. When the front baffle 6 needs to be opened, first rotate the vertical rods of the L-shaped round rods 611 on both sides to vertically upward, and then... Push the front baffle 6 to one side until the left side of the L-shaped rod 611 is in the clearance groove 615. Then the front baffle 6 can be flipped forward to open. When the front baffle 6 needs to be closed, flip the front baffle 6 backward. When it is close to the upright plate 2, rotate the vertical rods of the L-shaped rods 611 on both sides upward to vertically upward and embed the front baffle 6 between the upright plate 2. Then pull the L-shaped rods 611 on both sides to both sides until the vertical rods of the L-shaped rods 611 are completely outside the upright plate 2. Then rotate the vertical rods of the L-shaped rods 611 downward to vertical. The horizontal rod of the L-shaped rod 611 is locked in the slot 612 on the upright plate 2, and its vertical rod is locked at the outer wall of the upright plate 2, thereby fixing the front baffle 6.

[0054] Preferably, a spring 616 is provided inside the convex groove 613, and the two ends of the spring 616 are respectively in contact with the inner wall of the convex groove 613 and the side wall of the protruding post 614. In the natural state, the horizontal bar of the L-shaped rod 611 is engaged in the slot 612 on the upright plate 2, and its vertical bar is engaged at the outer side wall of the upright plate 2, thereby fixing the front baffle 6 and improving the stability of the locking assembly 61.

[0055] Preferably, the front baffle 6 is provided with a plurality of top blocks 63 in the middle that contact the front sidewall of the partition 53 on the test tube rack 5. The top blocks 63 can contact the front sidewall of the partition 53 to prevent the test tube rack 5 from sliding freely in the placement area and improve the stability of the test tube rack during use.

[0056] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
