Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube rack technology, and in particular to a centrifuge tube rack. Background Technology

[0002] Centrifuge tube racks are equipment used to hold centrifuge tubes.

[0003] A search revealed that patent CN220573539U discloses a porous centrifuge tube rack, but this centrifuge tube rack has the following shortcomings in use:

[0004] While centrifuge tube racks can hold centrifuge tubes, their length is fixed. When the centrifuge tube racks are not in use and need to be stored together, they take up a large storage space, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing centrifuge tube racks, which, although capable of holding centrifuge tubes, have fixed lengths and occupy a large storage area when not in use and require centralized storage, thus causing inconvenience. Therefore, this invention proposes a centrifuge tube rack.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A centrifuge tube rack includes a main body for placing centrifuge tubes. The main body is composed of a first frame and a second frame. The first frame consists of a first fixed plate, a U-shaped frame, and a concave plate. One side of the concave plate is fixedly connected to one side of the first fixed plate, and one side of the U-shaped frame is slidably connected to one side of the first fixed plate. The second frame consists of a second fixed plate, a first movable plate, and a second movable plate. A T-shaped slider is fixedly provided on one side of the first movable plate, and a T-shaped groove is formed on one side of the second fixed plate. One side of the T-shaped slider is slidably connected to the inner wall of the T-shaped groove. One side of the second movable plate is fixedly connected to one side of the second fixed plate. The concave plate is concave, and the outer side of the second movable plate is slidably connected to the inner wall of the concave plate. The top and bottom of the first movable plate are slidably connected to the top inner wall and bottom inner wall of the U-shaped frame, respectively. Placement holes for placing centrifuge tubes are provided on both the U-shaped frame and the first movable plate. An identification card for marking the dimensions of the main body of the centrifuge tube rack is attached to one side of the first fixed plate.

[0008] A fixing mechanism is installed on the first frame to fix the second frame;

[0009] An adjustment mechanism is installed on the first frame to adjust the height of the U-shaped frame and the first movable plate.

[0010] In one possible design, the fixing mechanism includes a threaded rod and a torsion bar that facilitates the rotation of the threaded rod. A threaded hole is provided on the concave plate, and the threaded rod is threadedly connected to the threaded hole. One side of the torsion bar is fixedly connected to one end of the threaded rod. An insertion hole is provided on one side of the second movable plate, and the other end of the threaded rod is inserted into the insertion hole.

[0011] In one possible design, the adjustment mechanism includes a second threaded rod, a movable block, and a knob for rotating the second threaded rod. A groove is provided on one side of the first fixed plate. The bottom end of the second threaded rod is rotatably connected to the inner wall of the bottom of the groove. One side of the movable block is slidably connected to the inner wall of one side of the groove. A second threaded hole is provided on the movable block. The second threaded rod is threadedly connected to the second threaded hole of the movable block. The top end of the second threaded rod passes through the top of the first fixed plate and is fixedly connected to the bottom of the knob. One side of the movable block is fixedly connected to one side of the U-shaped frame.

[0012] In one possible design, the bottom of the first fixing plate and the bottom of the second fixing plate are flush.

[0013] In one possible design, the bottom inner wall of the concave plate is provided with a limiting groove for limiting the second movable plate when it is pulled out, and a limiting block is fixedly provided at the bottom of the second movable plate, with the bottom of the limiting block slidably connected to the inner wall of the limiting groove.

[0014] In one possible design, the bottom of both the first fixing plate and the bottom of the second fixing plate are fixedly provided with rubber pads for anti-slip when the centrifuge tube rack is placed.

[0015] In one possible design, both the top of the concave plate and the top of the second movable plate are provided with placement slots for placing the bottom end of the centrifuge tube.

[0016] In this application, during use, the first and second frames are held with both hands and pulled in opposite directions to unfold the centrifuge tube rack body. Through the set limiting groove, when the second movable plate in the second frame moves to a certain position within the concave plate, it will be limited to prevent detachment. When it cannot be pulled any further, the insertion hole and threaded rod of the second movable plate are aligned. Then, the toggle bar is rotated, which drives the rotation of the threaded rod, causing one end of the threaded rod to insert into the insertion hole, thereby fixing the first and second frames and preventing them from sliding against each other. The centrifuge tube rack body is then placed on a table. When the height of the U-shaped frame and the first movable plate needs to be adjusted according to the length of the centrifuge tubes, the knob is rotated. The rotation of the knob drives the rotation of the second threaded rod, which in turn drives the movement of the movable block. The movement of the movable block drives the movement of the U-shaped frame and the first movable plate, thus allowing for height adjustment. Finally, the centrifuge tubes are inserted into the placement holes of the U-shaped frame and the first movable plate, and the bottom end of the centrifuge tubes is placed in the placement groove for placement.

[0017] When the centrifuge tube rack is not in use and needs to be centrally stored, turn the knob. The rotation of the knob will cause the threaded rod to rotate, so that one end of the threaded rod leaves the insertion hole of the second moving plate. Then push the second frame into the first frame. Since the first and second frames slide against each other, the length of the centrifuge tube rack can be adjusted and reduced, thereby reducing the area occupied by the centrifuge tube rack. After the second frame is pushed into the first frame, the knob can be turned again to make one end of the threaded rod fit tightly against one side of the second moving plate, effectively preventing slippage. The placement hole on the U-shaped frame can be larger than the placement hole on the first moving plate, so that two centrifuge tubes of different thicknesses can be placed. The placement hole on the U-shaped frame and the placement hole on the first moving plate can also be the same size, which can be designed according to actual needs.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this utility model, the centrifuge tube rack can be adjusted and reduced in length by sliding between the first frame and the second frame, thereby reducing the area occupied by the centrifuge tube rack.

[0020] In this utility model, the centrifuge tube rack, through an adjustment mechanism, rotates a knob, which in turn rotates a second threaded rod, which in turn moves a moving block, which in turn moves a U-shaped frame and a first moving plate, thereby allowing the height of the U-shaped frame and the first moving plate to be adjusted.

[0021] In this utility model, the centrifuge tube rack, through a fixing mechanism, the rotation of the knob drives the rotation of the threaded rod, so that one end of the threaded rod is inserted into the insertion hole, thereby fixing the first rack and the second rack and preventing them from sliding against each other;

[0022] In this invention, the length of the centrifuge tube rack can be adjusted and reduced by sliding between the first frame and the second frame, thereby reducing the area occupied by the centrifuge tube rack. The first frame and the second frame can be fixed by the fixing mechanism to prevent them from sliding against each other. The height of the U-shaped frame and the first movable plate can be adjusted by the adjustment mechanism. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figure 1-4 A centrifuge tube rack, used in the field of centrifuge tube racks, includes: a centrifuge tube rack body, a first frame 1, and a second frame 2. The first frame 1 is composed of a first fixing plate 3, a U-shaped frame 4, and a concave plate 5. One side of the concave plate 5 is connected to one side of the first fixing plate 3 by welding or other fixing methods. One side of the U-shaped frame 4 is slidably connected to one side of the first fixing plate 3, so that the U-shaped frame 4 can slide up and down on the first fixing plate 3.

[0031] The second frame 2 consists of a second fixed plate 7, a first movable plate 6, and a second movable plate 8. A T-shaped slider is fixedly installed on one side of the first movable plate 6, and a T-shaped groove is formed on one side of the second fixed plate 7. The T-shaped slider is slidably connected to the inner wall of the T-shaped groove, allowing the first movable plate 6 to slide up and down on the second fixed plate 7. One side of the second movable plate 8 is connected to one side of the second fixed plate 7 by welding or other fixing methods.

[0032] The concave plate 5 has a concave structure, and the outer side of the second movable plate 8 is slidably connected to the inner wall of the concave plate 5, so that the second frame 2 can slide relative to the first frame 1. The top and bottom of the first movable plate 6 are slidably connected to the top inner wall and bottom inner wall of the U-shaped frame 4, respectively (the first movable plate 6 can slide left and right), so that the U-shaped frame 4 can drive the first movable plate 6 to move together when it slides up and down.

[0033] Both the U-shaped frame 4 and the first movable plate 6 have placement holes for placing centrifuge tubes. An identification card 17 is attached to one side of the first fixed plate 3 to mark the dimensions of the centrifuge tube rack body, making it convenient for users to understand and use.

[0034] To fix the position of the second frame 2, a fixing mechanism is also provided. This fixing mechanism includes a threaded rod 12 and a torsion bar 10. A threaded hole is provided on the concave plate 5, and the threaded rod 12 is threadedly connected to the threaded hole. One side of the torsion bar 10 is fixedly connected to one end of the threaded rod 12, facilitating rotation of the threaded rod 12 by the user. An insertion hole 11 is provided on one side of the second movable plate 8. After the position of the second frame 2 is adjusted, the threaded rod 12 can be rotated by rotating the torsion bar 10, causing the other end of the threaded rod 12 to be inserted into the insertion hole 11, thereby fixing the position of the second frame 2.

[0035] To adjust the height of the U-shaped frame 4 and the first movable plate 6, an adjustment mechanism is provided on the first frame 1. The adjustment mechanism includes a second threaded rod 16, a movable block, and a knob 15. A groove is formed on one side of the first fixed plate 3. The bottom end of the second threaded rod 16 is rotatably connected to the inner wall of the bottom of the groove via a bearing, allowing the second threaded rod 16 to rotate within the groove. One side of the movable block is slidably connected to the inner wall of one side of the groove. A second threaded hole is formed on the movable block, and the second threaded rod 16 is threadedly connected to the second threaded hole of the movable block. Rotating the knob 15 rotates the second threaded rod 16, thereby causing the movable block to move up and down. One side of the movable block is fixedly connected to one side of the U-shaped frame 4, so when the movable block moves up and down, it can move the U-shaped frame 4 together. Simultaneously, since the first movable plate 6 is slidably connected to the U-shaped frame 4, the movement of the U-shaped frame 4 will also cause the first movable plate 6 to move together.

[0036] Example 2

[0037] refer to Figure 1-4An improvement based on Example 1:

[0038] Both the top of the concave plate 5 and the top of the second movable plate 8 are provided with placement grooves 9 for placing the bottom ends of the centrifuge tubes, increasing the stability of the centrifuge tubes. The bottom of the first fixed plate 3 and the bottom of the second fixed plate 7 are flush to ensure the stability of the centrifuge tube rack during placement. At the same time, a limiting groove 13 is also provided on the inner wall of the bottom of the concave plate 5, and a limiting block is fixedly provided on the bottom of the second movable plate 8. The bottom of the limiting block is slidably connected to the inner wall of the limiting groove 13 to limit the pull-out position of the second movable plate 8 and prevent it from sliding out excessively.

[0039] To facilitate the placement and movement of centrifuge tube racks, rubber pads 14 are fixedly installed at the bottom of the first fixing plate 3 and the bottom of the second fixing plate 7. The rubber pads 14 can increase the friction between the centrifuge tube rack and the placement surface, preventing the centrifuge tube rack from sliding on the plane.
