Description
Technical Field
[0001] The present invention relates to the technical field of sample transfer trays, and particularly to an anti-tipping tray for sample transfer in a laboratory department. Background Art
[0002] The anti-tipping tray for sample transfer in a laboratory department is a special equipment for safely transporting various test samples. It is mainly used in places such as hospitals and laboratories to transfer samples such as blood, body fluids, and tissues after collection from the collection point to the test department. Through an adjustable fixing structure, a dynamic balance device, and a buffer sealing design, this tray can adapt to sample containers of different specifications, effectively fix the samples during the transfer process, and prevent the containers from tipping over. At the same time, through an active protection design, a comprehensive sample protection system is constructed to ensure the stability and integrity of the samples during transportation, providing a reliable sample basis for subsequent test work.
[0003] Traditional sample transfer trays mostly adopt a static support structure and lack dynamic adjustment capabilities. They cannot actively cope with the bumps and tilts during the transfer process. When the operator walks and sways, the ground is uneven, or there is a handling collision, it is difficult for the tray to maintain balance, easily causing the sample containers to tip over, resulting in sample leakage and cross-contamination problems. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the present invention provides an anti-tipping tray for sample transfer in a laboratory department, which solves the problem that the existing transfer trays are difficult to actively cope with the bumps during the transfer process, resulting in leakage.
[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An anti-tipping tray for sample transfer in a laboratory department, including a fixed frame. Both the left and right sides of the fixed frame are fixedly connected with fixed blocks. The tops of both fixed blocks are fixedly connected with handles. The front side inside the fixed frame is fixedly connected with a first motor. The output end of the first motor is fixedly provided with a rotating frame. The rear side of the rotating frame is rotatably connected to the fixed frame. The right side of the rotating frame is fixedly connected with a second motor. The output end of the second motor is fixedly provided with a placing member. The left side of the placing member is rotatably connected to the rotating frame. A sealing assembly is arranged on the top of the placing member.
[0006] By adopting the above technical solutions, the active adjustment of the angle of the placing member during the transfer process of the tray is realized. It can adjust the posture of the placing member in real time according to the overall tilt situation, so that the sample containers inside the placing member always maintain a horizontal and stable state, thereby effectively avoiding the samples from spilling, tipping over, or colliding with each other due to tilting, and improving the safety and stability of sample transfer.
[0007] Preferably, the sealing assembly includes a fixing member, which is fixedly connected to the placing member. Covers are rotatably connected to both the front and rear sides of the fixing member. Two rotating rods are rotatably connected to the bottom of each cover. A connecting member is rotatably connected between the bottoms of two adjacent rotating rods in the front and rear. A counterweight is fixedly connected between the bottoms of the two connecting members.
[0008] Preferably, a knob is rotatably connected to the front side of the placing member. A threaded rod is fixedly connected to the rear end of the knob. A plurality of moving blocks are threadedly connected to the surface of the threaded rod. Connecting rods are rotatably connected to the bottoms of the plurality of moving blocks. Push rods are rotatably connected to both the left and right sides of the plurality of connecting rods.
[0009] Preferably, a plurality of pressing members are arranged inside the placing member. The plurality of pressing members are slidably connected to the placing member. First springs are fixedly connected between the plurality of pressing members and the placing member.
[0010] Preferably, a plurality of placing grooves are formed in the top of the placing member. A plurality of soft pads are fixedly connected to the bottoms of the two covers.
[0011] Preferably, a plurality of second springs are fixedly connected to the bottom of the inner wall of the placing member. Support members are fixedly connected to the tops of the plurality of second springs. Circular grooves are formed in the tops of the plurality of support members.
[0012] Preferably, a sliding rod is fixedly connected between the front and rear sides inside the placing member. The sliding rod is slidably connected to the two moving blocks.
[0013] Preferably, a horizontal detector is fixedly connected to the bottom of the counterweight. A controller is fixedly connected to the bottom of the counterweight. The horizontal detector is electrically connected to the controller. The controller is electrically connected to the first motor and the second motor.
[0014] Preferably, a rectangular groove is formed in the bottom of the placing member. The rectangular groove has the same size as the counterweight.
[0015] Preferably, one side of each of the plurality of pressing members close to the placing groove is arc-shaped, and one side of each of the plurality of pressing members close to the placing groove is made of silicone rubber.
[0016] Working principle: The user places the sample into the placing groove at the top of the placing member, and rotates the knob on the front side of the placing member to drive the threaded rod to rotate. Since the threads at both ends of the threaded rod are opposite, the plurality of moving blocks move relative to each other under the guidance of the sliding rod, driving the connecting rods and push rods at the bottom. The push rods push the plurality of pressing members, and the pressing members fit the contour of the sample container, realizing the adaptive fixation of sample test tubes of different models. At the same time, the second springs and support members at the bottom of the inner wall of the placing member provide elastic support and positioning for the sample through the circular grooves.
[0017] Then the user holds the handle on the top of the fixing block to lift the transfer tray. The counterweight block at the bottom of the placement piece moves downward due to its own weight, pulling the connecting piece and the rotating rod, so that the front and rear side covers of the fixing piece automatically cover the placement piece. The soft pad at the bottom of the cover contacts the sample container for buffering and enhancing fixation. During transportation, the horizontal detector at the bottom of the counterweight block monitors the horizontality of the placement piece in real time. Once tilt occurs, the signal is transmitted to the controller, and the controller starts the first motor and the second motor. The first motor drives the rotating frame to adjust the left and right angles, and the second motor drives the placement piece to adjust the front and rear angles to ensure that the placement piece is always horizontal. When transported to the designated location and the tray is placed on the desktop, the placement piece presses the counterweight block to move it into the bottom rectangular groove, and the counterweight block lifts the connecting piece and the rotating rod to automatically open the cover, making it convenient for users to take and place sample containers.
[0018] The present invention provides a sample transport anti-dumping tray for a laboratory, which has the following beneficial effects:
[0019] 1. The present invention detects the horizontality of the placement piece in real time through a horizontal detector at the bottom. When the whole piece is tilted, the controller starts the first motor and the second motor. The first motor drives the rotating frame to rotate and adjust the left and right angles, and the second motor drives the two sides to rotate and adjust the front and back angles, so as to ensure that the sample container inside the placement piece always maintains a horizontal and stable state, and avoids the samples from spilling, tipping over or colliding with each other due to tilting.
[0020] 2. The present invention lowers the center of gravity and increases stability by arranging a counterweight at the bottom of the placement piece. When the placement piece is disturbed by external force, the counterweight helps to reduce the shaking and tilting of the tray, making the tray less likely to tip over, further ensuring the stable placement of the sample container.
[0021] 3. The present invention allows the user to lift the entire device for transportation by lifting the handles on both sides. When lifting, the counterweight block at the bottom moves downward due to its own weight, and the counterweight block pulls the two connecting parts to move downward. The connecting parts pull the rotating rod to move, so that the two cover plates automatically cover the placement parts to complete the sealing protection of the samples and prevent the samples from being exposed to the external environment during transportation. At the same time, after the cover plates are closed, the sample container can be further compressed to reduce the shaking of the samples.
[0022] 4. The present invention drives the threaded rod to rotate by turning the knob on the front side. Since the threads at both ends of the threaded rod are opposite, the two moving blocks move relatively when the threaded rod rotates, driving the connecting rod and the push rod at the bottom to move, so that the push rod pushes the extrusion piece to move. At this time, the extrusion piece squeezes the sample in the placement groove, thereby realizing rapid fixation of sample tubes of different models. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0031] Next, in combination with the accompanying drawings of the present invention, the technical solutions of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] Please refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention provides a sample transfer anti-tipping tray for a clinical laboratory, including a fixed frame 1, fixed blocks 2 are fixedly connected to both the left and right sides of the fixed frame 1, handles 3 are fixedly connected to the tops of the two fixed blocks 2, a first motor 5 is fixedly connected to the front side inside the fixed frame 1, a rotating frame 4 is fixedly arranged at the output end of the first motor 5, the rear side of the rotating frame 4 is rotatably connected to the fixed frame 1, a second motor 6 is fixedly connected to the right side of the rotating frame 4, a placement member 8 is fixedly arranged at the output end of the second motor 6, the left side of the placement member 8 is rotatably connected to the rotating frame 4, and a sealing assembly is arranged on the top of the placement member 8.
[0033] Specifically, the user places the sample on top of the placement member 8 and holds the handle 3 at the top of the fixed block 2 to lift the transfer tray. During transportation, once the tray tilts, the horizontal detector 12 at the bottom of the placement member 8 monitors the level in real time and transmits a signal to the controller 27. The controller 27 activates the first motor 5 and the second motor 6. The first motor 5 drives the rotating frame 4 to rotate to adjust the left - right angle of the tray, and the second motor 6 drives the placement member 8 to rotate to adjust the front - back angle of the tray. The two work together to ensure that the placement member 8 is always in a horizontal state, enabling the internal sample containers to be stably placed, preventing the samples from spilling, toppling, or colliding with each other, and ensuring the safety and stability of the samples throughout the transportation process.
[0034] See the appendix Figure 3 and the appendix Figure 4 As shown in the figure, the sealing assembly includes a fixing member 7, which is fixedly connected to the placement member 8. Both the front and rear sides of the fixing member 7 are rotatably connected with cover plates 10. Both the bottom surfaces of the cover plates 10 are rotatably connected with two rotating rods 15. A connecting member 13 is rotatably connected between the bottoms of two adjacent front - rear rotating rods 15. A counterweight 11 is fixedly connected between the bottoms of the two connecting members 13.
[0035] Specifically, when the user holds the handle 3 at the top of the fixed block 2 and is about to lift the transfer tray, the counterweight 11 at the bottom of the placement member 8 starts to move downward due to its own gravity. The counterweight 11 drives the two connecting members 13 to move downward together. The connecting members 13 pull the rotating rods 15 to move. Under the pulling force of the connecting members 13, the cover plates 10 are driven to rotate around the fixing member 7, so that the two cover plates 10 automatically cover the placement member 8, completing the sealing protection of the sample placed on the placement member 8, avoiding the sample being exposed to the external environment during transportation, preventing the sample from spilling and being contaminated. At the same time, after the cover plates 10 are closed, they can further press the sample containers, cooperate with other fixing structures to reduce the shaking of the samples during transportation. When the whole is transported to the designated position and placed on the table, at this time, the counterweight 11 will move into the rectangular groove at the bottom of the placement member 8. At this time, the counterweight 11 jacks up the connecting member 13, driving the rotating rod 15 to move, thereby realizing the automatic opening of the top cover plate 10, facilitating the user to take and place the sample containers.
[0036] See the appendix Figure 5 and the appendix Figure 6 As shown in the figure, a knob 9 is rotatably connected to the front side of the placement member 8. The rear end of the knob 9 is fixedly connected to a threaded rod 22. A plurality of moving blocks 21 are threadedly connected to the surface of the threaded rod 22. The bottoms of the plurality of moving blocks 21 are rotatably connected with connecting rods 20. Both the left and right sides of the plurality of connecting rods 20 are rotatably connected with push rods 19.
[0037] Specifically, the user places the sample in the placement groove 16 and rotates the knob 9 to drive the threaded rod 22 to rotate. Since the surface of the threaded rod 22 is provided with threads and the threads at both ends are opposite, when the threaded rod 22 rotates, the moving block 21 will move relatively. The connecting rod 20 rotatably connected to the bottom of the moving block 21 will also change its position as the moving block 21 moves. The push rods 19 rotatably connected to the left and right sides of the connecting rod 20 move under the drive of the connecting rod 20. Finally, the push rods 19 push the pressing member 17 to press the sample in the placement groove 16, thereby realizing the rapid fixation of sample test tubes of different models, meeting the needs of diversified sample transportation in the inspection department, ensuring that sample test tubes of various specifications can be stably fixed during transportation, and avoiding sample shaking and tipping caused by insecure fixation.
[0038] Refer to the appendix Figure 5 and the appendix Figure 6 As shown in the figure, multiple pressing members 17 are arranged inside the placement member 8. The multiple pressing members 17 are all slidably connected to the placement member 8, and a first spring 18 is fixedly connected between the multiple pressing members 17 and the placement member 8.
[0039] Specifically, multiple independent pressing members 17 are arranged inside the placement member 8 and are connected by the first spring 18 at the same time. When samples of different specifications are placed on the placement member 8, rotating the knob 9 causes the push rod 19 to move towards the pressing member 17. Since the push rod 19 is rotatably connected to the connecting rod 20 and the connecting rod 20 is rotatably connected to the moving block 21, the push rod 19 can rotate freely when pushing the pressing member 17, so that the moving degree of the pressing member 17 can be adapted to the size of the sample test tube. The pressing member 17 can fit the shape of the sample during the sliding process, realizing the fixation of samples of different models.
[0040] Refer to the appendix Figure 3 and the appendix Figure 4 As shown in the figure, multiple placement grooves 16 are opened at the top of the placement member 8, and multiple soft pads 14 are fixedly connected to the bottom of both cover plates 10.
[0041] Specifically, the placement groove 16 provides a specific placement position for the sample container, enabling the samples to be placed neatly and orderly, facilitating classification and fixation, preventing the samples from rolling randomly or colliding with each other during transportation. When the cover plate 10 is closed, the soft pad 14 can contact the sample container, playing a buffering and protecting role, avoiding direct hard contact between the cover plate 10 and the sample container and causing damage. At the same time, the soft pad 14 can also increase the friction force, further fixing the sample container, reducing its shaking during transportation, and better protecting the sample.
[0042] Refer to the appendix Figure 7 As shown in the figure, multiple second springs 24 are fixedly connected to the bottom of the inner wall of the placement member 8. The top ends of the multiple second springs 24 are all fixedly connected with support members 25, and circular grooves 26 are opened at the tops of the multiple support members 25.
[0043] Specifically, the support member 25 provides elastic support and positioning for the samples placed on the placement member 8. When sample tubes of different lengths are placed in the placement groove 16, the second spring 24 presses against the support member 25 to make it fit against the bottom of the sample tube, buffering vibrations and impact forces during transportation, protecting the samples from jolts. The circular groove 26 can be adapted to the bottom of the sample container, playing a positioning role, making the placement of the samples more stable, preventing them from shaking or shifting within the placement member 8, and further improving the safety and stability of the samples during transportation.
[0044] Refer to the appendix Figure 5 and the appendix Figure 7 Refer to the appendix, a slide bar 23 is fixedly connected between the front and rear sides inside the placement member 8, and the slide bar 23 is slidably connected to two moving blocks 21.
[0045] Specifically, the slide bar 23 provides guidance and support for the moving block 21, enabling the moving block 21 to smoothly move left and right along the slide bar 23 under the drive of the threaded rod 22, preventing it from shifting or shaking during movement.
[0046] Refer to the appendix Figure 2 Refer to the appendix, a horizontal detector 12 is fixedly connected to the bottom of the counterweight 11, a controller 27 is fixedly connected to the bottom of the counterweight 11, the horizontal detector 12 is electrically connected to the controller 27, and the controller 27 is electrically connected to the first motor 5 and the second motor 6.
[0047] Specifically, the horizontal detector 12 can monitor the level of the placement member 8 in real time. When the placement member 8 is tilted, the horizontal detector 12 transmits the detected tilt signal to the controller 27. The controller 27 activates the first motor 5 and the second motor 6 according to the received signal. The first motor 5 drives the rotating frame 4 to rotate and adjust the left - right angle, and the second motor 6 drives the placement member 8 to rotate and adjust the front - rear angle, so that the sample containers inside the placement member 8 always maintain a horizontal and stable state, preventing the samples from spilling, toppling, or colliding with each other due to tilting, and improving the safety and reliability of sample transportation.
[0048] Refer to the appendix Figure 2 Refer to the appendix, a rectangular groove is formed at the bottom of the placement member 8, and the rectangular groove has the same size as the counterweight 11.
[0049] Specifically, the rectangular groove at the bottom of the placement member 8 enables the placement member 8 to press against the counterweight 11 due to its own weight when the whole is placed on the table. At this time, the counterweight 11 will move into the rectangular groove at the bottom of the placement member 8 for storage, thereby realizing that the counterweight 11 presses against the connecting member 13 and the rotating rod 15 to automatically open the cover plate 10.
[0050] Refer to the appendix Figure 5 and the appendix Figure 6, the sides of multiple pressing members 17 close to the placement groove 16 are all arc-shaped, and the sides of multiple pressing members 17 close to the placement groove 16 are all made of silicone rubber.
[0051] Specifically, the arc-shaped sides of multiple pressing members 17 close to the placement groove 16 can better fit the contour of the sample container, providing a more uniform pressing force to stably fix the sample container in the placement groove 16 and prevent it from shaking or shifting. The sides of multiple pressing members 17 close to the placement groove 16 are made of silicone rubber, which has good elasticity and flexibility. It can adapt to sample containers of different shapes and sizes during pressing, avoiding hard damage to the sample container. At the same time, the silicone rubber material also has a certain anti-slip property, which can further enhance the fixing effect on the sample container and ensure the safety of the sample during transportation.
[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
