Description

Technical Field

[0001] The utility model belongs to the field of experimental instruments, relates to the field of test tube racks, and specifically relates to a pharmaceutical test tube rack. Background Art

[0002] Pharmacy involves drug research and development, quality control, and clinical application. During pharmaceutical research, test tubes are often used to hold and mix reagents, and they are widely used in various experimental procedures. After the test tubes are filled and mixed, they are placed in a test tube rack to facilitate observation of the experimental phenomena within the tubes. After use and cleaning, the test tube rack provides a place to store the test tubes, facilitating their neat placement and ease of management and use.

[0003] The structure of a commonly used test tube rack is mainly based on a frame structure with holes for placing test tubes. To facilitate the insertion and removal of test tubes and to accommodate test tubes of different diameters within a certain range, the holes are usually slightly larger than the test tubes themselves. Therefore, when a test tube is placed in the hole, the test tube will shake inside the hole. The hard material of the test tube rack can easily cause the test tube to collide and wear with the hole, which increases the risk of damage to the test tube. In addition, when the test tube is placed in the hole, the bottom frame of the test tube rack is needed to support the test tube. To avoid the test tube from impacting the bottom of the test tube rack, the test tube needs to be placed gently so that the test tube is in contact with the bottom of the frame to prevent damage. At the same time, the frame structure of the commonly used test tube rack is not stable enough. When placing a heavy test tube, the test tube rack may tilt or shake, increasing the risk of test tube breakage. Therefore, the commonly used test tube rack has certain disadvantages. Utility Model Content

[0004] To address the technical problem of unstable use and the resulting wear and tear on test tubes in currently used test tube racks, this utility model provides a pharmaceutical test tube rack. A counterweight is added to the bottom of the rack to increase the support area while lowering the center of gravity, ensuring stability. Furthermore, a rubber pad connected to a storage bag is placed in the through hole to isolate and support the test tubes, preventing wear and tear between the test tubes and the rack, thereby ensuring the safety of the test tube support.

[0005] The technical solution adopted by the utility model is: to provide a pharmaceutical test tube rack, including a frame with a "mouth"-shaped cross-section, through holes uniformly opened on the top of the frame along the length direction, annular rubber pads are inserted in the through holes, both ends of the rubber pads protrude from the through holes, and the top of the rubber pads is provided with outwardly convex edges, the edges are in contact with the top surface of the frame, the bottom of the rubber pads is connected to a transparent storage bag, and a gap is provided between the bottom of the storage bag and the bottom of the frame; a counterweight block is detachably installed on the bottom of the frame, blind holes are opened on the bottom surface of the counterweight block along the circumferential direction, suction cups are provided in the blind holes, screws are rotatably provided on the top of the suction cups, the tops of the screws pass through the top surface of the counterweight block upwards, and the screws are threadedly connected to the counterweight block.

[0006] A counterweight is installed at the bottom of the frame, and the counterweight is placed on the supporting surface to support the frame. The counterweight lowers the center of gravity of the test tube rack, and the suction cup arranged in the blind hole on the bottom of the counterweight pushes the suction cup downward and adsorbed on the supporting surface through the screw thread engagement with the counterweight, thereby enhancing the firmness of the test tube rack support. After the rubber pad connected to the storage bag is inserted into the through hole on the frame, the protruding edge of the top of the rubber pad abuts against the top surface of the frame, supporting the rubber pad in the through hole, and the test tube is placed in the storage bag by the rubber pad, and the storage bag supports the test tube. A gap is provided between the bottom of the storage bag and the bottom of the frame to prevent the test tube from colliding with the bottom of the frame. At the same time, the rubber pad prevents the test tube from contacting and colliding with the top of the frame, thereby ensuring the safety of the test tube placement. The transparent material of the storage bag does not interfere with the observation of the test tube.

[0007] To further optimize the technical solution, the frame includes a top beam and a bottom beam arranged upper and lower, the top beam and the bottom beam are arranged in parallel, and vertical beams are provided on both sides of the length direction between the top beam and the bottom beam; the two ends of the vertical beam are respectively connected to the top beam and the bottom beam; the through holes are evenly distributed on the top beam, and the bottom beam and the counterweight block can be detachably installed.

[0008] The through holes are distributed on the top beam of the frame, the bottom beam of the frame is assembled with the counterweight, and the vertical beams of the frame support the top beam and the bottom beam, so that the frame structure is stable, the frame structure is simple, and the production cost is low.

[0009] To further optimize this technical solution, a material storage trough is provided in the center of the top surface of the counterweight block, and a cover plate is sealed on the top of the material storage trough. The cover plate is flush with the top surface of the counterweight block, and the counterweight block can be detachably installed with the help of a connecting piece and the bottom beam.

[0010] By adding materials into the storage trough on the counterweight block, the weight of the counterweight block is increased, and the center of gravity of the frame is lowered to ensure stability in use. The storage trough is sealed with a cover to prevent material leakage. After the bottom beam and the counterweight block are installed, the cover plate is restricted to ensure reliability in use.

[0011] To further optimize this technical solution, the connecting part includes a screw groove arranged on the top surface of the counterweight block and a mounting hole arranged on the bottom beam. The screw grooves are distributed around the cover plate. The mounting holes correspond to the position and number of the screw grooves, and bolts are inserted into the mounting holes, which are respectively threadedly connected to the screw grooves.

[0012] The screw grooves are distributed around the cover plate and do not interfere with the use of the cover plate. After the mounting holes on the frame bottom beam coincide with the screw grooves, they are tightened and fixed with bolts. The operation is easy, the assembly structure is simple, and the use is stable and reliable.

[0013] To further optimize the technical solution, the bag opening of the storage bag is sleeved on the bottom of the rubber pad and is fixed to the rubber pad with the help of a locking piece.

[0014] By putting the bag opening of the storage bag on the bottom of the rubber pad and locking it on the rubber pad, the rubber pad and the storage bag are connected, and the test tubes can be placed smoothly, the operation is simple, and the storage bag can be easily disassembled and assembled, making it flexible to use.

[0015] To further optimize the technical solution, an annular groove is provided at the bottom of the outer wall of the rubber pad, the opening of the storage bag covers the groove, and the locking piece is engaged with the groove.

[0016] The storage bag is constrained by assembling the locking piece in the groove, and the groove constrains the position of the locking piece to prevent it from falling off the rubber pad, thereby ensuring the firmness of the storage bag connection.

[0017] To further optimize the technical solution, the locking member includes a hoop, which is arranged on the outer wall of the storage bag and is engaged with the groove, and the hoop protrudes from the groove.

[0018] After the clamp is put on the outer wall of the storage bag and placed in the groove, it is stuck in the groove as the clamp is tightened, and the storage bag is tightened and fixed on the rubber pad, thereby enhancing the reliability of the connection between the storage bag and the rubber pad. The clamp has a simple structure, is easy to use, and has low cost.

[0019] To further optimize the technical solution, the bottom surface of the counterweight block is provided with an anti-slip pad, and the anti-slip pad matches the shape of the bottom surface of the counterweight block.

[0020] The anti-slip pad increases the contact friction between the counterweight and the supporting surface, so that the counterweight supports the test tube rack stably.

[0021] To further optimize this technical solution, a polygonal butt joint is provided on the top of the screw, a handle is connected to the screw via the butt joint, and a butt joint groove matching the butt joint is provided on the handle, and the butt joint groove is connected to the butt joint.

[0022] After the docking groove on the handle is plugged into the docking joint on the screw, the screw is rotated by the handle to engage with the thread of the counterweight block to adjust the position of the suction cup, making the operation more labor-saving and simple.

[0023] The beneficial effects of the present invention are:

[0024] 1. Fill the material storage tank on the counterweight block with materials to increase its own weight. After the cover plate seals the storage tank to prevent material leakage, the bottom beam of the frame is placed on the counterweight block and tightened with bolts to constrain and fix the cover plate to ensure reliability. The counterweight block lowers the center of gravity of the test tube rack to ensure stability.

[0025] 2. After the counterweight is placed on the support surface, the anti-slip pad on the bottom of the counterweight increases the contact friction with the support surface, making the placement more stable. After the screw is rotated by the handle, the suction cup in the blind hole on the bottom of the counterweight moves downward and contacts the support surface. After the air in the suction cup is emptied, the suction cup is adsorbed on the support surface, thereby enhancing the firmness of the counterweight on the support surface and ensuring the firmness of the test tube rack support.

[0026] 3. After the rubber pad connected to the storage bag is placed in the through hole of the top beam, the convex edge of the top of the rubber pad abuts against the top beam, supporting the rubber pad in the through hole. After the test tube is placed in the storage bag through the rubber pad, there is a gap between the bottom of the storage bag and the bottom beam to prevent the test tube from colliding with the bottom beam. At the same time, the rubber pad prevents the test tube from contacting and wearing the top beam. In addition, the storage bag shields and protects the test tube, ensuring the safety of the test tube support. The transparent material of the storage bag does not interfere with the observation of the test tube, and it is flexible to use.

[0027] 4. Put the opening of the storage bag on the bottom of the rubber pad and cover the groove on the rubber pad, then place the clamp in the groove. As the clamp is tightened, the clamp is stuck in the groove and the storage bag is tightened and fixed on the rubber pad. The protruding edges of the clamp and the rubber pad prevent the rubber pad from falling off from the through hole. The clamp is convenient for disassembly and replacement of the storage bag, and it is flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS
