Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an easily adjustable test tube rack partition. Background Technology

[0002] A test tube rack is a standard laboratory device used to support and secure test tubes. It typically has multiple grooves or holes to hold and secure the test tubes. Some test tube racks also come with small wooden posts for inverting washed test tubes to dry. The main purpose of a test tube rack is to provide stable support for the test tubes, prevent them from rolling or tipping over, ensure their safety during experiments or storage, and facilitate sampling, reaction, and testing operations by laboratory personnel.

[0003] A search of Chinese patent publication number "CN209565019U" reveals a "test tube rack" that adds an elastic body to the existing test tube rack. The diameter of the elastic body is slightly smaller than that of the test tube. When the test tube is in use, it serves to fix the test tube. When the test tube is not in use or needs to drain water, the test tube is passed through the elastic body and then the test tube rack is inverted, which can drain water and avoid contact contamination of the test tube opening.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. However, when conducting experiments, due to different process requirements, the test tubes used in the same experiment also vary in size, so the types are often uncertain. The test tube rack cannot be clearly and intuitively classified and separated, which is not conducive to subsequent use and lacks convenience, and needs to be improved. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides an easily adjustable test tube rack partition, which solves the technical problem of insufficient convenience of the existing device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An adjustable test tube rack partition, comprising a test tube rack body;

[0010] The test tube rack body has symmetrical adjustment structures on its side wall;

[0011] The adjustment structure includes a bracket, and a fixing screw is threaded between the two brackets and the test tube rack body. The two brackets are symmetrically provided with stepped grooves, and damping bearings are provided inside the two stepped grooves. The outer ring of each damping bearing is fixedly installed with the stepped groove.

[0012] Preferably, each of the inner rings of the stepped grooves is fixedly installed with a rotating shaft between each pair, and a plastic gear is fixedly installed on the circumferential surface of each of the two rotating shafts. The rotation of the rotating shafts can be maintained by the plastic gears at any current rotation angle through the damping bearings, and a limiting plate is provided inside the test tube rack body.

[0013] Preferably, the test tube rack body and the limiting plate are both provided with through grooves, and a partition body is slidably installed between the two grooves. The partition body is located inside the support and is made of smooth plastic material. The partition body is provided with symmetrical grooves inside, and a plastic rack assembly is fixedly installed inside each of the two grooves. Both plastic rack assemblies are parallel to the plastic gears.

[0014] Preferably, both of the plastic rack assemblies are meshed with plastic gears, limit baffles are symmetrically fixedly installed on the surface of the partition body, and rotating handles are symmetrically fixedly installed on the side walls of the two rotating shafts, with both rotating handles partially exposed outside the bracket.

[0015] Preferably, both rotating handles are located inside the stepped groove and are rotatably installed. The test tube rack body has a base plate inside, which is located below the limiting plate. The lower end of the partition body is attached to the base plate.

[0016] (III) Beneficial Effects

[0017] Firstly, by setting up an adjustment structure, the operator can rotate the shaft by turning the handle, which in turn drives the plastic gear to rotate and mesh with the plastic rack assembly. At this time, the plastic rack assembly will generate an upward radial force, which will drive the entire partition body to move upward. This allows the entire partition body to move upward within the sliding groove inside the test tube rack body and the limiting plate, thereby completing the adjustment. This allows the test tube rack to accommodate test tubes of different sizes for classification, improving the efficiency and convenience of the test tube rack body and reducing laboratory costs.

[0018] Secondly, by utilizing the meshing transmission of plastic rack and pinion gears to adjust the partition body, it is possible to avoid the normal operation of the adjustment structure being affected when some sand or debris is blown into the adjustment structure during public environment sampling, thus improving reliability.

[0025] This application provides an easily adjustable test tube rack partition, effectively solving the technical problem of insufficient convenience in existing devices. By setting an adjustment structure, the operator can rotate the shaft by turning the handle, which in turn drives the plastic gear to rotate and mesh with the plastic rack assembly. At this time, the plastic rack assembly will generate an upward radial force, causing the partition body to move upward as a whole. This allows the partition body to move upward within the sliding groove inside the test tube rack body and the limiting plate, thereby completing the adjustment. This allows the test tube rack to accommodate test tubes of different sizes for classification, improving the efficiency and convenience of the test tube rack body, reducing laboratory costs, and using the meshing transmission of the plastic rack assembly and plastic gear to adjust the partition body. This avoids the problem of sand or debris being blown into the adjustment structure during collection in public environments, ensuring that the normal operation of the adjustment structure is not affected, thus improving reliability.

[0026] Example

[0027] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient convenience of existing devices. The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the present invention provides an easily adjustable test tube rack partition, including a test tube rack body 11;

[0029] The test tube rack body 11 has symmetrical adjustment structures on its side walls;

[0030] The adjustment structure includes a bracket 12. A fixing screw 13 is threaded between the two brackets 12 and the test tube rack body 11. The two brackets 12 are symmetrically provided with stepped grooves 14. The two stepped grooves 14 are provided with damping bearings 15. The outer ring of each damping bearing 15 is fixedly installed with the stepped groove 14. The inner rings of each stepped groove 14 are fixedly installed with two rotating shafts 16. Plastic gears 17 are fixedly installed on the circumferential surface of the two rotating shafts 16. The rotation of the rotating shafts 16 can maintain the plastic gears 17 at any current rotation angle through the damping bearings 15. The test tube rack body 11 is provided with a limiting plate 18.

[0031] By setting an adjustment structure, the operator can rotate the handle 25 to rotate the shaft 16, which in turn drives the plastic gear 17 to rotate and mesh with the plastic rack assembly 23. At this time, the plastic rack assembly 23 will generate an upward radial force to drive the partition body 21 to move upward as a whole. This causes the partition body 21 to move upward within the sliding groove 19 inside the test tube rack body 11 and the limiting plate 18, thereby completing the adjustment. This allows the test tube rack to accommodate test tubes of different sizes for classification, improving the efficiency and convenience of the test tube rack body 11 and reducing laboratory costs.

[0032] A damping bearing is a type of bearing that generates damping force during motion. When the shaft 16 rotates, the damping bearing 15 will generate a certain resistance to its rotation. This resistance does not prevent the shaft 16 from rotating, but rather makes the rotation of the shaft 16 smooth and controllable. Therefore, the rotation of the shaft 16 can be maintained at any current rotation angle by the plastic gear 17 through the damping bearing 15.

[0033] Both the test tube rack body 11 and the limiting plate 18 have through grooves 19. A partition body 21 is slidably installed between the two grooves 19. The partition body 21 is made of smooth plastic material and is located inside the bracket 12.

[0034] By opening a groove 19 inside the test tube rack body 11 and the limiting plate 18, when the plastic gear 17 rotates and meshes with the plastic rack assembly 23, the partition body 21 moves upward inside the groove 19 inside the test tube rack body 11 and the limiting plate 18, thereby providing a limit and increasing stability.

[0035] The partition body 21 has symmetrically provided grooves 22 inside. Plastic rack assemblies 23 are fixedly installed inside each of the two grooves 22. Both plastic rack assemblies 23 are parallel to the plastic gear 17 and are meshed with the plastic gear 17. Limiting baffles 24 are symmetrically fixedly installed on the surface of the partition body 21. Rotating handles 25 are symmetrically fixedly installed on the side walls of the two rotating shafts 16. Both rotating handles 25 are partially exposed outside the bracket 12.

[0036] By utilizing the meshing transmission of the plastic rack and pinion assembly 23 and the plastic gear 17 to adjust the partition body 21, it is possible to avoid the normal driving of the adjustment structure when some sand or debris is blown into the adjustment structure during collection in a public environment, thus improving reliability.

[0037] Both rotating handles 25 are located inside the stepped groove 14 and are rotatably installed. The test tube rack body 11 has a base plate 26 inside, which is located below the limiting plate 18. The lower end of the partition body 21 is attached to the base plate 26.

[0038] By setting the rotating handle 25, it is convenient for staff to drive the adjustment structure using the rotating handle 25.

[0039] Working principle:

[0040] When the height of the partition body 21 needs to be adjusted, the operator can first rotate the rotating handles 25 on the two supports 12 simultaneously. At this time, the rotation of the rotating handles 25 will generate a radial force to drive the rotating shaft 16 connected to the rotating handles 25 to rotate, which in turn drives the plastic gear 17 to rotate and mesh with the plastic rack assembly 23. At this time, the plastic rack assembly 23 will generate an upward radial force to drive the partition body 21 to move upward as a whole, so that the partition body 21 moves upward within the sliding groove 19 inside the test tube rack body 11 and the limiting plate 18, thereby completing the adjustment. At the same time, the setting of the damping bearing 15 can prevent the partition body 21 from falling automatically, which would cause inaccurate adjustment.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
