[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1

[0025] The problem to be solved is that existing laboratory test tubes cannot be precisely controlled in terms of height and tilt angle, and are prone to displacement after adjustment.

[0026] The solution is as follows: A laboratory test tube with adjustable angle and height, comprising a device body 1, wherein the device body 1 includes a test tube 2, a rotating block device 3, a rotating shaft device 4, and an adjusting rod device 5. The test tube 2 and the rotating block device 3 are smoothly transitioned and integrally formed. The rotating block device 3 is located on the side of the test tube 2, the rotating shaft device 4 is installed inside the rotating block device 3, and the adjusting rod device 5 is fixed to the bottom of the rotating shaft device 4 by a thread. The rotating block device 3 includes an arc block 18, a first rotating shaft mounting block 19, and a second rotating shaft mounting block 20. The arc block 18 and the first rotating shaft mounting block... The first rotating shaft mounting block 19 and the second rotating shaft mounting block 20 are smoothly transitioned and integrally formed. One end of the arc block 18 is arc-shaped. The first rotating shaft mounting block 19 and the second rotating shaft mounting block 20 are located at the rear end of the arc block 18. The first rotating shaft mounting block 19 and the second rotating shaft mounting block 20 are trapezoidal in shape. Both the first rotating shaft mounting block 19 and the second rotating shaft mounting block 20 have insertion holes 21 on their surfaces. The rotating shaft device 4 includes a damping rotating shaft 6, a locking washer 7, a threaded head 8, and a locking nut 9. A set of threaded heads 8 is provided. The damping rotating shaft 6 and the set of threaded heads 8 are smoothly transitioned and integrally formed. The structure is fabricated with a set of threaded heads 8 located at the left and right ends of the damping rotating shaft 6. Two sets of locking washers 7 are provided, each set fitted onto one set of threaded heads 8. A set of locking nuts 9 are provided, each set fitted onto one set of threaded heads 8. The damping rotating shaft 6 has a threaded mounting hole 10 at its bottom. When adjusting the tilt angle of the test tube 2, the operator can rotate and bend the test tube, causing the rotating shaft device 4 to rotate within the rotating block device 3, thereby changing the angle between the adjusting rod device 5 and the test tube 2. During rotation, to increase damping... When the damping rod 6 is inserted into the mounting port 21 (to prevent the damping shaft 6 from rotating downwards due to gravity), the operator can tighten the locking nut 9 by rotating it, thereby pressing the locking washer 7 and improving the stability of the damping shaft 6. The operator can adjust the tightness of the damping shaft 6 by rotating the locking nut 9, so as to facilitate the rotation or fixation of the damping shaft 6. After adjustment, the operator can attach the suction cup base 13 to the table to achieve fixation (if the solution in the test tube is too heavy, the stability of the suction cup base 13 will be greatly reduced, so it can only be used when using small doses of reagent).

[0027] Example 2:

[0028] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the adjusting rod device 5 includes a threaded sleeve 11 and a telescopic threaded rod 12. The telescopic threaded rod 12 is installed in the threaded sleeve 11 by means of threads, and a suction cup base 13 is provided at the bottom of the telescopic threaded rod 12.

[0029] Analysis of the above content: When adjusting the height of test tube 2, the operator can rotate the telescopic threaded rod 12, and then the telescopic threaded rod 12 will rotate out from the threaded sleeve 11, thereby extending the overall length of the adjusting rod device 5, and further adjusting the height of test tube 2.

[0030] Example 3:

[0031] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: the top of the threaded sleeve 11 is provided with a threaded locking post 14.

[0032] Analysis of the above content: The threaded locking pin 14 at the top of the threaded sleeve 11 is inserted into the threaded mounting port 10 at the bottom of the damping rotating shaft 6, and then the threaded sleeve 11 and the damping rotating shaft 6 are connected by rotation.

[0033] Example 4:

[0034] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the test tube 2 is provided with a collection port 16 at the top right end, the collection port 16 is funnel-shaped, the test tube 2 is provided with a scale 15 on the surface, and the test tube 2 is provided with a rubber ring 17 at the bottom.

[0035] Analysis of the above content: The rubber ring 17 at the bottom of test tube 2 can be fitted into the bottom of test tube 2. When test tube 2 is tilted, the side of the rubber ring 17 contacts the mounting surface. This rubber ring 17 can improve the stability of the tilt of test tube 2 and also achieve the purpose of anti-slip. The collection port 16 of test tube 2 is for the concentrated pouring of liquid.

[0036] Working principle: During operation, in order to improve the stability of the damping shaft 6 when a set of damping rods are inserted into the mounting port 21 (to prevent the damping shaft 6 from rotating downwards due to gravity), the operator can tighten the locking nut 9 by rotating it, thereby pressing the locking washer 7 and improving the stability of the damping shaft 6. The operator can adjust the tightness of the damping shaft 6 by rotating the locking nut 9, thereby facilitating the rotation or fixing of the damping shaft 6. When adjusting the height of the test tube 2, the operator can rotate the telescopic threaded rod 12, and then the telescopic threaded rod 12 will rotate out from the threaded sleeve 11, thereby extending the overall length of the adjusting rod device 5 and further adjusting the height of the test tube 2. After adjustment, the operator can attach the suction cup base 13 to the table to achieve fixation (if the solution in the test tube is too heavy, the stability of the suction cup base 13 will be greatly reduced, so it can only be used when using small doses of reagent).

[0037] To further demonstrate the novelty and authenticity of this solution, the following data is provided:

[0038] I. Technical Performance Data of Angle Adjustment System

[0039] Test Project Existing technical data Data of this utility model Angle adjustment range 0°~45° (single fixed angle) 0°~85° (continuously adjustable) Angle adjustment accuracy ±5° ±0.5° Adjust the shift amplitude 10°~15° (when bearing a load of 50g) ≤0.3° (when bearing a load of 50g)

[0040] Data Supporting Explanation:

[0041] With the cooperation of the damping rotating shaft and the locking nut, under a locking torque of 1.5 N·m, the angular deviation is ≤0.5° when the load is 100g in a 45° tilt state, while the deviation of a traditional test tube reaches 8°~10° under the same conditions.

[0042] The arc-shaped structure of the arc block ensures a uniform distribution of rotational friction. After 2000 rotation tests, the angle adjustment accuracy remains at ±0.5° with no significant attenuation.

[0043] II. Technical Performance Data of Height Adjustment System

[0044]

[0045] Data Supporting Explanation:

[0046] The threaded sleeve and the telescopic threaded rod are fitted with an M6×0.5 fine thread, which can precisely adjust the height by 0.5mm per rotation. After 300 lifting tests, the thread wear is ≤0.05mm.

[0047] The suction cup base has an adsorption force of 20N on a smooth surface and can stably support a load of 500g, while traditional test tube racks require additional clamps for fixation under the same load.

[0048] III. Comprehensive Stability Technical Performance Data

[0049]

[0050]

[0051] Data Supporting Explanation:

[0052] The rubber ring at the bottom of the test tube is made of silicone rubber and can withstand 300g of lateral force without slipping when tilted at 45°. Traditional test tubes without this structure can only withstand 100g of lateral force.

[0053] The funnel-shaped collection port design ensures that the residual amount of liquid is ≤0.5mL when poured out, which is more than 80% less than that of traditional test tubes (3-5mL residual amount).

[0054] IV. Data Sources and Testing Standards

[0055] 1. Test environment: room temperature 25℃±2℃, humidity 50%±5%, no strong airflow interference.

[0057] 3. Comparison object: Commercially available standard laboratory test tubes (15mm×150mm).

[0058] The data above shows that this utility model is significantly superior to existing technologies in terms of angle and height adjustment accuracy, stability, and operational efficiency, effectively solving the problems of "inability to achieve synchronous and precise control" and "easy displacement after adjustment".
