Description

Technical Field

[0001] This utility model relates to the field of medical testing, specifically to a test tube holder for medical testing that prevents tipping. Background Technology

[0002] In the field of medical testing, test tubes are the core carriers for sample storage and reaction. Their placement stability directly affects the accuracy of test results and the safety of operation. Currently, most conventional medical testing test tube holders on the market are made of plastic or metal frames, and the test tubes are placed in batches by opening array-type through holes.

[0003] Most products rely solely on the weight of their base for stability, without any dedicated reinforcement structure. When testing personnel move other equipment on the lab bench or accidentally bump into the holder, it can cause the test tubes to shake, potentially spilling samples, or even cause the entire holder to tip over. This can damage the test tubes and samples, and may also pose safety hazards due to glass fragments or leakage of biological samples. Therefore, we have proposed a tipping-proof test tube holder for medical testing. Utility Model Content

The sliding groove is located on the side of the placement plate away from the bottom plate and is perpendicular to the placement plate. Each of the two side plates has a plurality of L-shaped slots that are equidistantly distributed along the sliding groove on its opposite side.

This avoids safety hazards such as test tube damage, sample spillage, and biological sample leakage. The adjustable stabilizing plate, together with the placement plate, can accommodate test tubes of different heights. The dual action of bottom support and middle limiting prevents test tubes from tilting, ensuring the stability of test sample storage and reaction processes, and improving the accuracy of test results. At the same time, the design of the ventilation component and the retractable auxiliary support structure balances stability and ease of operation, saving storage space when not in use, and meeting the efficient and safe use requirements of medical testing scenarios.

[0021] Furthermore, each of the two side plates 1 has a sliding groove 6 on its opposite side. The sliding groove 6 is on the side of the placement plate 4 away from the bottom plate 2 and is perpendicular to the placement plate 4. Each of the two side plates 1 has multiple L-shaped slots 7 that are equidistantly distributed along the sliding groove 6 on its opposite side.

The circular through holes of the stabilizing plate 3 are used to stabilize the middle of the test tube.

[0023] Furthermore, the base plate 2 is a hollow structure, and multiple equally spaced suction cups 5 are connected through the side of the two base plates 2 facing away from the side plate 1. The air tubes of the suction cups 5 are fixedly connected to the base plate 2, and the suction cups 5 are used to adhere to the placement platform of the fixed frame.

When the support rod 2 11 is needed for support, the support rod 18 is rotated to move out of the strip groove 13. The elastic force of the spring 12 causes the support rod 2 11 to extend out of the support rod 18 and support it on the placement platform of the fixed frame.

[0029] Structural Description: Side plate 1: It is plate-shaped and serves as the main support component of the fixed frame. It connects the base plate 2 and the placement plate 4. It also has a sliding groove 6 and an L-shaped slot 7 for installing the stabilizing plate 3, forming the two side frames of the fixed frame. Base plate 2: It is a hollow plate located at the bottom of the fixing frame, supporting the side plate 1. The bottom surface is connected to the suction cup 5. It can contain air and, together with the ventilation component, enables the suction cup to be adsorbed and fixed, providing a bottom support base for the fixing frame. Stabilizing plate 3: It is plate-shaped and has locking blocks 15 on both sides. The spacing between the plate 4 and the side plate 1 is adjusted by the locking blocks 15 cooperating with the sliding grooves 6 and L-shaped grooves 7 of the side plate 1. The circular through holes on the plate are used to stabilize the middle of the test tube and are suitable for test tubes of different heights. Placement plate 4: It is plate-shaped and fixed between two side plates 1 and close to the bottom plate 2. Multiple evenly distributed through holes are opened on the plate to support the bottom of the test tube and provide a bottom support point for the test tube. Suction cup 5: It has a bowl-shaped elastic structure and the air tube is connected to the base plate 2. It fits the table surface of the experimental table and discharges the internal air through deformation. It is adsorbed to the table surface by means of air pressure difference, which enhances the stability of the bottom of the fixing frame. Slide groove 6: A long strip groove opened on the opposite side of the side plate 1, which allows the locking block 15 of the stabilizing plate 3 to slide up and down, providing a sliding path for adjusting the height of the stabilizing plate 3, and cooperating with the L-shaped locking groove 7 to achieve the positioning of the stabilizing plate; L-shaped groove 7: It is an L-shaped groove opened on the opposite side of the side plate 1 and evenly distributed along the slide groove 6, with one end connected to the slide groove 6. The locking block 15 locks the stabilizing plate 3, fixes the stabilizing plate 3 at a specific height, and prevents the stabilizing plate from sliding. Support rod 18: It is a hollow rod with one end open and the two ends open near the bottom plate. Support rod 21 and spring 12 are installed to provide a basic frame for the auxiliary support structure. It can rotate around the pivot 14 to realize storage and unfolding. Internal threaded tube 9: It is a tube with internal threads, which is connected to the side of the base plate 2 away from the suction cup 5. It is equipped with screw 10 and provides a carrier for the rotation and sealing of screw 10. It works with screw 10 to control the air circulation inside and outside the base plate 2. Screw 10: It is cylindrical with limiting blocks at both ends, a vent groove 16 at one end, and a vent hole 17 on the cylindrical surface. A sealing cavity is provided at one end of the screw 10 outside the internal thread tube 9. A gasket is provided in the sealing cavity. It rotates inside the internal thread tube 9. The relative position change between the vent hole 17 and the internal thread tube 9 controls the communication or isolation of air inside and outside the base plate 2, so as to realize the adsorption and release of the suction cup 5. The limiting block prevents the screw from falling off the internal thread tube 9. Support rod 2 11: It is rod-shaped and can be inserted into support rod 1 8. Under the action of spring 12, it extends out from support rod 1 8, and its bottom contacts the experimental table surface. It cooperates with suction cup 5 to form multi-point support and enhance the anti-tipping ability of the fixed frame. Spring 12: It has a spiral elastic structure, with one end fixed inside the support rod 18 and the other end connected to the support rod 21. It provides elastic force to push the support rod 211 out of the support rod 18. When the support rod 211 is retracted, it can be compressed for easy storage. Strip groove 13: A long strip-shaped groove opened on the side of the side plate 1 that is not connected to the placement plate 4 and close to the bottom plate 2, to store the support rod 8, providing storage space for the auxiliary support structure and avoiding taking up extra space when not in use; Rotating shaft 14: It is cylindrical and fixed on both sides of the support rod 8 and the strip groove 13. It cooperates with the hinge hole 18 of the strip groove 13 to realize the rotation of the support rod 8, so that the support rod 8 can rotate out of the strip groove 13 or rotate back into the groove. Block 15: It is block-shaped and fixed on both sides of the stabilizing plate 3. It is embedded in the sliding groove 6 and L-shaped slot 7 of the side plate 1, which drives the stabilizing plate 3 to slide along the sliding groove 6. After being inserted into the L-shaped slot 7, the position of the stabilizing plate 3 is fixed. Ventilation slot 16: is a slot-shaped structure opened at one end of the screw 10 located inside the base plate 2, connecting the internal space of the base plate 2 with the ventilation hole 17 of the screw 10, providing a channel for air circulation inside and outside the base plate 2; Vent hole 17: It is a hole-like structure opened on the cylindrical surface of screw 10 and extending to vent groove 16. As screw 10 rotates, it forms an on / off connection with internal thread tube 9 to control the air discharge in base plate 2 or the air in outside, and adjust the air pressure inside and outside suction cup 5. Hinge hole 18: It is a hole-like structure opened on both sides of the strip groove 13 and the rotating shaft 14 to accommodate and cooperate with the rotation of the rotating shaft 14, providing a hinge point for the rotation of the support rod 8, and ensuring that the support rod 8 can be flexibly unfolded and stored.

[0030] Working principle: When using, first place the mounting bracket in the designated position on the experimental table, ensuring that the suction cup 5 on the bottom surface of the base plate 2 is completely in contact with the table surface. At this time, the base plate 2 is a hollow structure. Pressing the mounting bracket deforms the suction cup 5, allowing internal air to flow through the base plate 2 to the ventilation assembly. In the initial state of the ventilation assembly, the internal threaded tube 9 and the screw 10 have their ventilation holes 17 located inside the internal threaded tube 9, isolating the inside of the base plate 2 from the outside. After pressing, rotating the screw 10 causes the ventilation holes 17 to disengage from the internal threaded tube 9, allowing the air inside the base plate 2 to escape through the ventilation groove 16 and the ventilation holes 17. Once the air is completely expelled, the process continues... Rotate screw 10 to allow vent 17 to re-enter internal threaded tube 9. The washer inside the sealing cavity of screw 10 fits tightly with internal threaded tube 9, again isolating internal and external airflow. Suction cup 5 adheres tightly to the table surface under the action of internal and external air pressure difference, completing the initial stabilization of the fixing frame. Next, adapt the test tube specifications and adjust the stabilizing plate. Adjust the position of stabilizing plate 3 according to the height of the test tube to be placed. Slide the locking blocks 15 on both sides of stabilizing plate 3 up and down along the sliding groove 6 of side plate 1. When the locking blocks 15 move to the position matching the height of the test tube, rotate stabilizing plate 3 so that the locking blocks 15 are locked into the L-shaped locking groove 7 of the corresponding height. At this time, The stabilizing plate 3 and the placement plate 4 form a suitable spacing. The through hole of the placement plate 4 is used to support the bottom of the test tube, while the circular through hole of the stabilizing plate 3 limits the middle of the test tube to prevent it from tilting. This accommodates the stable placement needs of test tubes of different lengths. When the fixed rack is full of test tubes, causing the center of gravity to shift upwards, or when the experimental table surface is slightly tilted, the auxiliary support structure can be activated. Through the rotatable connection between the pivot 14 and the hinge hole 18, the support rod 8 is rotated out from the strip groove 13 of the side plate 1. The support rod 8 is a hollow structure, and the internal spring 12 is initially in a compressed state. After being rotated out, the spring 12 releases its elasticity, pushing the support rod 8 out of the slot 13 of the side plate 1. Support rod 2 11 extends from the open end of support rod 1 8 until its bottom contacts the table surface, forming multi-point support together with the suction cup stabilizing structure, further reducing the risk of the fixed frame tipping over. When the fixed frame needs to be moved, rotate screw 10 to disengage vent hole 17 from internal threaded tube 9, allowing outside air to enter the base plate 2 through vent hole 17 and vent groove 16, balancing the air pressure inside and outside the suction cup 5, and easily removing the fixed frame. At the same time, press support rod 2 11 to compress spring 12, retracting it into support rod 1 8, and then rotate support rod 1 8 back into strip groove 13 via pivot 14 to complete storage and save storage space.
