Description

Technical Field

[0001] This utility model relates to the field of laboratory testing technology, specifically to a sample preservation device for laboratory testing. Background Technology

[0002] Laboratory testing samples refer to various materials used in laboratory experiments. These samples are usually extracted from a batch of goods for external display, product quality testing, or testing before mass production. To assist in the preservation of laboratory testing samples, a laboratory testing sample preservation device is needed.

[0003] Traditional laboratory sample preservation devices typically store samples inside the device during use. However, traditional devices are prone to shaking when the sample tubes are placed inside, affecting the stability of the sample storage. Furthermore, when retrieving samples of the same type, traditional devices require removing individual sample tubes one by one and placing the retrieved sample tubes into an external support, which reduces the efficiency of sample retrieval.

[0006] As a preferred embodiment of this utility model, an outer cylinder is fixedly mounted on the side of the inner wall of the storage box, a sliding cylinder is slidably sleeved on the inner wall of the outer cylinder, a sliding rod is fixedly sleeved on the inner wall of the sliding cylinder, and the sides of the sliding rod and the sliding cylinder overlap with the side of the placement frame.

[0007] As a preferred embodiment of this utility model, the outer edge of the slide rod is slidably sleeved with an inner cylinder, and the side of the inner cylinder is fixedly assembled with the side of the inner wall of the storage box. A magnet ring is fixedly assembled with the side of the slide rod, and a coil is fixedly sleeved on the inner wall of the outer cylinder, and the inner wall of the coil is slidably sleeved with the outer edge of the magnet ring.

[0008] As a preferred embodiment of this utility model, a magnet piece 1 is fixedly mounted at both ends of the inner wall of the arc-shaped groove, and a magnet piece 2 is fixedly mounted on both sides of the limiting plate, and the two magnet pieces 2 are attracted to the adjacent sides of the two magnet pieces 1.

[0009] As a preferred embodiment of this utility model, a fixing frame is fixedly mounted on the side of the side plate, a square plate is slidably connected to the inner wall of the fixing frame, a diagonal rod is fixedly mounted on the side of the square plate, and the outer edge of the diagonal rod passes through the inner wall of the side plate and is slidably connected to the inner wall of the storage box. A second spring is fixedly connected to the side of the square plate, and the end of the second spring away from the square plate is fixedly connected to the side of the inner wall of the fixing frame. A pull rod is fixedly mounted on the side of the square plate, and the outer edge of the pull rod is slidably sleeved with the inner wall of the fixing frame.

[0010] As a preferred embodiment of this utility model, the number of placement plates is three, and the inner walls of the three placement plates are each provided with three sample tubes. A rotating cylinder is provided on both sides of each placement plate, and the connection structure between the two rotating cylinders and the two sides of one placement plate is completely identical.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This laboratory sample preservation device uses a side plate and a placement frame in conjunction. The side plate moves the placement frame via a connecting rod, which in turn moves the inclined rod into the inner wall of the fixed frame. Then, a spring pushes a square plate within the inner wall of the fixed frame, which in turn moves the outer edge of the inclined rod against the inner wall of the preservation box. During the sliding of the placement frame, the side of the placement frame engages with the sides of the sliding rod and the sliding cylinder. The outer edge of the sliding rod slides within the inner wall of the inner cylinder, the outer edge of the sliding cylinder slides within the inner wall of the outer cylinder, and the inner wall of the sliding cylinder slides within the outer edge of the inner cylinder. This causes the magnetic ring to slide within the inner wall of the coil, and the coil generates electromagnetic damping on the magnetic ring, thus assisting the placement frame in shock absorption.

[0013] 2. This laboratory sample preservation device uses an arc-shaped groove and a limiting plate in combination. By rotating the round rod, the outer edge of the limiting plate rotates within the inner wall of the arc-shaped groove, which helps the adjacent sides of magnet one and magnet two separate. Then, the outer edge of the round rod slides within the inner wall of the cylinder, which in turn drives the outer edge of the limiting plate to slide within the inner wall of the slide groove, moving the placement plate away from the placement frame. This helps the placement plate separate the sample tube from the device. Attached Figure Description

A rotating cylinder 5 is rotatably connected to the side of the inner wall of the placement frame 4. A sliding groove 6 is formed on the side of the rotating cylinder 5. An arc-shaped groove 7 is formed on the side of the inner wall of the sliding groove 6, and a limiting plate 9 is rotatably connected to the inner wall of the arc-shaped groove 7. A round rod 11 is fixedly mounted on the side of the limiting plate 9. A rotating plate 14 is rotatably connected to the side of the round rod 11. A cylinder 12 is slidably sleeved on the outer edge of the rotating plate 14. A spring 13 is fixedly connected to the side of the rotating plate 14.

A rubber pad 17 is fixedly mounted on the inner wall of the placement plate 15. A sample tube 16 is slidably sleeved on the inner wall of the rubber pad 17. Through the cooperation of the spring 13 and the rotating plate 14, the spring 13 pushes the rotating plate 14 to move. The rotating plate 14 drives the outer edge of the limiting plate 9 to overlap with the side of the inner wall of the arc groove 7 through the round rod 11. Through the cooperation of the sample tube 16 and the rubber pad 17, the rubber pad 17 clamps and limits the sample tube 16 in the inner wall of the placement plate 15, thereby helping to fix the sample tube 16 in the inner wall of the placement plate 15.

[0024] In a preferred embodiment, an outer cylinder 23 is fixedly mounted on the side of the inner wall of the storage box 1. A slide cylinder 24 is slidably sleeved on the inner wall of the outer cylinder 23. A slide rod 25 is fixedly sleeved on the inner wall of the slide cylinder 24. The sides of both the slide rod 25 and the slide cylinder 24 overlap with the sides of the placement frame 4. Through the cooperation of the outer cylinder 23 and the slide cylinder 24, the outer edge of the slide cylinder 24 slides in the inner wall of the outer cylinder 23, and the slide cylinder 24 drives the slide rod 25 to move.

[0025] In a preferred embodiment, the outer edge of the slide rod 25 is slidably sleeved with the inner cylinder 26, and the side of the inner cylinder 26 is fixedly assembled with the side of the inner wall of the storage box 1. The side of the slide cylinder 24 is fixedly assembled with a magnet ring 27, and the inner wall of the outer cylinder 23 is fixedly sleeved with a coil 28, and the inner wall of the coil 28 is slidably sleeved with the outer edge of the magnet ring 27. Through the cooperation of the inner cylinder 26 and the slide rod 25, the outer edge of the slide rod 25 slides in the inner wall of the inner cylinder 26, and the slide cylinder 24 drives the magnet ring 27 to slide in the inner wall of the coil 28. Thus, the coil 28 generates electromagnetic damping on the magnet ring 27, thereby assisting in shock absorption of the placement frame 4.

[0026] In a preferred embodiment, a first magnet 8 is fixedly mounted at both ends of the inner wall of the arc-shaped groove 7, and a second magnet 10 is fixedly mounted on both sides of the limiting plate 9. The two second magnets 10 are attracted to the adjacent sides of the two first magnets 8. Through the cooperation of the first magnets 8 and the second magnets 10, the attraction between the first magnets 8 and the second magnets 10 helps to stably limit the limiting plate 9 in the inner wall of the arc-shaped groove 7.

[0027] In a preferred embodiment, a fixed frame 18 is fixedly mounted on the side of the side plate 2. A square plate 20 is slidably connected to the inner wall of the fixed frame 18. A diagonal rod 22 is fixedly mounted on the side of the square plate 20, and the outer edge of the diagonal rod 22 passes through the inner wall of the side plate 2 and is slidably connected to the inner wall of the storage box 1. A spring 21 is fixedly connected to the side of the square plate 20, and the end of the spring 21 away from the square plate 20 is fixedly connected to the side of the inner wall of the fixed frame 18. A pull rod 19 is fixedly mounted on the side of the square plate 20, and the outer edge of the pull rod 19 is slidably sleeved with the inner wall of the fixed frame 18. Through the cooperation of the spring 21 and the square plate 20, the spring 21 pushes the square plate 20 in the inner wall of the fixed frame 18, thereby using the square plate 20 to drive the outer edge of the diagonal rod 22 to assist the side plate 2 and the storage box 1 in limiting their positions. With the addition of the pull rod 19, the pull rod 19 assists the square plate 20 in driving the diagonal rod 22 for convenient position adjustment.

[0028] In a preferred embodiment, there are three placement plates 15, and each of the three placement plates 15 has three sample tubes 16 on its inner wall. Each of the two placement plates 15 has a rotating cylinder 5 on both sides, and the connection structure of the two rotating cylinders 5 is completely consistent with that of the two sides of one placement plate 15. By adding three placement plates 15, it is convenient to place the three sets of sample tubes 16 in the inner wall of the three placement plates 15 respectively. Then, by moving a single placement plate 15, the three sample tubes 16 can be easily taken out.

[0029] Working principle: When the device is in use, the side plate 2 moves the placement frame 4 via the connecting rod 3, thereby moving the inclined rod 22 into the inner wall of the fixed frame 18. Then, the spring 21 pushes the square plate 20 within the inner wall of the fixed frame 18, causing the outer edge of the inclined rod 22 to be positioned against the inner wall of the storage box 1. During the sliding of the placement frame 4, the side of the placement frame 4 engages with the sides of the sliding rod 25 and the sliding cylinder 24. The outer edge of the sliding rod 25 slides within the inner wall of the inner cylinder 26, the outer edge of the sliding cylinder 24 slides within the inner wall of the outer cylinder 23, and the inner wall of the sliding cylinder 24 slides within the outer edge of the inner cylinder 26. The sliding cylinder 24 drives the magnet ring 27 to slide within the inner wall of the coil 28, thereby generating electromagnetic damping on the magnet ring 27, which in turn helps the placement frame 4 to reduce vibration. The rotating rod 11 drives the outer edge of the limiting plate 9 to rotate within the inner wall of the arc groove 7, which in turn helps the adjacent sides of the magnet piece 1 8 and the magnet piece 2 10 to separate. Then, the outer edge of the rod 11 slides within the inner wall of the cylinder 12, which in turn drives the outer edge of the limiting plate 9 to slide within the inner wall of the sliding groove 6, thereby moving the placement plate 15 away from the placement frame 4, which in turn helps the placement plate 15 to separate the sample tube 16 from the device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
