Description

Technical Field

[0001] This utility model relates to the technical field of laboratory instruments, specifically an adjustable heating clamping device for laboratories. Background Technology

[0002] In laboratories, especially in experiments in chemistry, physics, and biology, test tubes are among the most common experimental instruments. Due to the diversity of test tube models and sizes, and the requirement for precise temperature control in experiments, higher demands are placed on the heating methods and effects of the test tubes. Uneven heating or inconsistent temperatures often lead to errors in experimental results, especially in experiments requiring precise temperature control, where temperature differences can directly affect the accuracy and repeatability of experimental data.

[0003] Most existing laboratory heating clamps are designed with a fixed height, which cannot accommodate height adjustments for test tubes of different sizes, making it difficult to guarantee consistent heating effects for different test tube models. Furthermore, the height adjustment function of traditional heating clamps is often complex or lacks effective control methods, making operation inconvenient and increasing the workload and time required for experiments.

[0004] Therefore, there is an urgent need for an adjustable heating clamping device that can be flexibly adjusted according to the height, length, and other characteristics of different test tubes to ensure that the test tubes maintain the same heating distance from the heat source, thereby guaranteeing that each test tube receives uniform heating conditions. This device not only improves the consistency of heating effects but also effectively reduces experimental errors caused by uneven heating, thus improving the reliability and repeatability of the experiment.

[0009] Furthermore, the inner wall of the threaded cylinder is provided with a buffer pad, and both the buffer pad and the inner side of the clamping tile are made of heat-resistant flexible material, including heat-resistant plastic and heat-resistant rubber.

[0010] Furthermore, four telescopic rods and corresponding support blocks are evenly arranged around the circumference.

[0011] Furthermore, the threaded cylinder is provided with a threaded groove corresponding to the threaded rod.

[0012] Furthermore, the support block is an inverted L-shaped structure with its face facing the axis, and the inner sidewall of the support block is arc-shaped and distributed in a circular pattern with the same center.

[0018] 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.

[0019] Combination Figures 1 to 3 Shown:

[0020] An adjustable heating clamping device for laboratory use includes a support plate 1 with an annular groove 2. An annular frame 3 is provided inside the annular groove 2. Several telescopic rods 4 are provided outward on the annular frame 3 to accommodate oil bath pots of different diameters. Support blocks 5 are provided on the top and bottom sides of the telescopic rods 4. Four telescopic rods 4 and corresponding support blocks 5 are evenly arranged around the circumference. The support blocks 5 have an inverted L-shaped structure facing the axis. The inner sidewall of the support blocks 5 is arc-shaped and distributed in a circumferential manner. This distribution effectively fixes the device to the edge of the oil bath heating pot, providing corresponding support while conforming to the circumferential structure of the pot edge.

[0021] The support plate 1 has several mounting holes 6 around the axis. A threaded cylinder 7 is installed in the mounting hole 6. The outer side of the threaded cylinder 7 is connected to the inner wall of the mounting hole 6 with corresponding internal and external threads. When the threaded cylinder 7 is rotated, it can move up and down.

[0022] A threaded fixing device 8 is provided on one side of the top of the threaded cylinder 7. The threaded cylinder 7 is provided with a threaded groove corresponding to the threaded rod 9. The threaded fixing device 8 includes the threaded rod 9. A clamping plate 10 is provided at the top of the inner side of the threaded rod 9. An adjusting knob 11 is provided at the top of the outer side of the threaded rod 9. The clamping plate 10 is controlled to clamp the test tube by rotating the adjusting knob 11, which makes it easy to adjust the clamping position of the test tube.

[0023] The inner wall of the threaded cylinder 7 is provided with a buffer pad 12. Both the buffer pad 12 and the inner side of the clamping tile 10 are made of heat-resistant flexible material, including heat-resistant plastic and heat-resistant rubber, which can clamp the test tube while preventing hard objects from scratching the test tube.

[0024] Working principle: The length of the telescopic rod is adjusted to fit the diameter of the oil bath. The support block fits into the edge of the oil bath for support. The test tube is placed inside the threaded cylinder. The position of the test tube is controlled by adjusting the knob to ensure that the test tubes are at the same height. After all the test tubes are installed, the height of the test tubes can be adjusted by rotating the threaded cylinder to ensure that the heating depth is corresponding and to ensure the consistency and stability of the heating conditions.
