Description

Technical Field

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

[0002] A test tube rack is an instrument used to support test tubes. It typically consists of two parts: a base and a frame. The base is used to fix and support the frame, while the frame holds the test tubes and keeps them in a stable position.

[0003] Test tube racks are a widely used instrument in laboratories, with common applications in fields such as chemistry, biology, and medicine.

[0004] Currently, test tube racks are divided into single-row and multi-row racks. Single-row test tube racks usually have only one row of test tubes, while multi-row test tube racks have multiple rows of test tubes.

[0005] Because a single-row test tube rack has only one row, it occupies relatively little space and is often used in laboratories or workspaces with limited space. However, in practical applications, it has been found that the small space occupied by the single-row test tube rack also results in a smaller area on the test bench, leading to insufficient stability and easy tipping over. If test tubes are placed inside the rack, they may slide out after tipping, posing a certain safety hazard. Therefore, improvements are proposed. Utility Model Content

[0006] This utility model is a test tube rack proposed to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a test tube rack, including a main frame, a mounting groove is provided at the bottom of the main frame, a plurality of suction cups are fixedly installed at the top of the mounting groove, and an air cavity is provided inside the main frame, and the suction cups are connected to the air cavity.

[0008] The three inner walls of the air chamber are fixedly connected to a partition, and a piston is sealed to the top of the partition. A manual telescopic rod is installed between the piston and the main frame.

[0009] The inner walls of both sides of the main frame are fixedly connected to two fixed perforated plates and one fixed base plate. Two movable perforated plates are provided below each of the two fixed perforated plates, and the movable perforated plates slide relative to the main frame. Two movable base plates are provided below the fixed base plate, and the movable base plates also slide relative to the main frame. Long rods are provided on both sides of the main frame, and the long rods are fixedly connected to two adjacent movable perforated plates and movable base plates.

[0010] Furthermore, multiple suction cup support seats are uniformly fixedly connected to the inner top of the mounting groove, and the suction cup support seats are matched with adjacent suction cups.

[0011] Furthermore, the manual telescopic rod includes a knob located on one side of the main frame. One end of the knob is fixedly connected to a screw, which penetrates the outer wall of the main frame and extends into the interior of the air chamber. The screw is rotatably connected to the main frame, and a movable sleeve is threaded onto the outer surface of the screw. The movable sleeve is fixedly connected to the piston.

[0012] Furthermore, six sliding grooves are provided on both inner walls of the main frame, and two adjacent sliding grooves extend to the outer walls of both sides of the main frame respectively. Limiting grooves are provided on one inner wall of each of the twelve sliding grooves.

[0013] Furthermore, each of the three movable perforated plates and the movable base plate is fixedly connected to a slide bar at both ends, and the slide bar is slidably connected to the adjacent slide groove. Each of the twelve slide bars is fixedly connected to a limit block at the end away from the adjacent long rod, and the limit block is located in the limit groove.

[0014] Furthermore, the outer wall of the piston is sealed and fitted to the inner wall of the air chamber.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model provides a test tube rack with mounting grooves, suction cups, air chambers, partitions, pistons, and manual telescopic rods. When using a single-row test tube rack, negative pressure can be used to fix the main frame to the test table, increasing its stability and making it less likely to be touched or tipped over, thus improving safety.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, a test tube rack is disclosed, including a main frame 1. The bottom of the main frame 1 has an installation groove 8. Multiple suction cups 7 are fixedly installed in the top inner part of the installation groove 8. An air cavity 11 is provided inside the main frame 1, and the suction cups 7 are connected to the air cavity 11. Multiple suction cup support seats 10 are evenly fixedly connected in the top inner part of the installation groove 8, and the suction cup support seats 10 are matched with adjacent suction cups 7. The suction cup support seats 10 have a supporting effect on the suction cups 7, ensuring the use effect of the suction cups 7.

[0027] A partition 19 is fixedly connected to the three inner walls of the air chamber 11. A piston 18 is sealed and fitted to the top of the partition 19. The outer wall of the piston 18 is sealed and fitted to the inner wall of the air chamber 11 to ensure the suction effect when the piston 18 moves. A manual telescopic rod is installed between the piston 18 and the main frame 1. The manual telescopic rod includes a knob 3, which is located on one side of the main frame 1. A screw 9 is fixedly connected to one end of the knob 3. The screw 9 passes through the outer wall of the main frame 1 and extends into the interior of the air chamber 11. The screw 9 is rotatably connected to the main frame 1. A movable sleeve 17 is threaded onto the outer surface of the screw 9. The movable sleeve 17 is fixedly connected to the piston 18. The screw 9 is connected to the main frame 1 by a bearing. The inner ring of the bearing is fixedly connected to the screw 9, and the outer ring of the bearing is fixedly connected to the main frame 1. An exhaust hole is opened on one inner wall of the air chamber 11 above the partition 19, extending to the outside of the main frame 1, to facilitate the movement of the piston 18.

[0028] The inner walls of both sides of the main frame 1 are fixedly connected to two fixed perforated plates 5 and one fixed base plate 2. Below each of the two fixed perforated plates 5 are two movable perforated plates 6, which slide relative to the main frame 1. Below the fixed base plate 2 are two movable base plates 12, which also slide relative to the main frame 1. Both sides of the main frame 1 are provided with long rods 4, which are fixedly connected to adjacent movable perforated plates 6 and movable base plates 12. The inner walls of both sides of the main frame 1 are provided with six sliding grooves 16, with adjacent sliding grooves 16 extending to the outer walls of both sides of the main frame 1. Each of the twelve sliding grooves 16 has a limiting groove 15 on one side of its inner wall. Each of the three movable perforated plates 6 and the movable base plate 12 is fixedly connected to a sliding strip 13 at both ends. The sliding strip 13 is slidably connected to the adjacent sliding groove 16. Each of the twelve sliding strips 13 is fixedly connected to a limiting block 14 at the end away from the adjacent long rod 4. The limiting block 14 is located in the limiting groove 15. The sliding groove 16 has a limiting function on the sliding strip 13, which can ensure the stability of the movement of the sliding strip 13, thereby ensuring the stability of the movement of the movable perforated plate 6 and the movable base plate 12. The limiting block 14 and the limiting groove 15 cooperate to prevent the sliding strip 13 from separating from the sliding groove 16.

[0029] Working principle: Place the main frame 1 on the test bench, then press down the main frame 1, and then turn the knob 3. The knob 3 drives the screw 9 to rotate, and the screw 9 drives the movable sleeve 17 to move to one side of the knob 3, thereby driving the piston 18 to move to one side of the knob 3, thereby generating a suction operation, reducing the gas pressure in the air chamber 11 at the bottom of the partition 19, increasing the negative pressure, and allowing the suction cup 7 to be firmly attached to the test bench. When it is necessary to temporarily increase the number of test tubes, pull the two long rods 4 on the left to move to the left, and pull the two long rods 4 on the right to move to the right. The two long rods 4 on the left drive the movable perforated plate 6 and the movable base plate 12 connected to them to move most of them out of the main frame 1 to form a new test tube rack. The same applies to the right side.
