Technical Field
[0001] This utility model relates to the field of temperature test chamber technology, specifically to a liftable temperature test chamber sample rack structure. Background Technology
[0002] Temperature testing is an essential part of various material testing and electronic component performance evaluation processes. To ensure the accuracy and reliability of test results, temperature test chambers are typically used to conduct experiments under high and low temperature environments. The sample holder, as a key component of the temperature test chamber, primarily serves to support the samples under test and adjust their position according to experimental requirements.
[0003] Most existing temperature test chamber sample racks adopt a fixed design. While this design can meet basic experimental needs, it is not flexible enough when faced with situations requiring frequent adjustments to sample height. Other solutions rely on complex mechanical structures or electric drive systems to achieve the lifting function of the sample rack. However, these methods not only increase the manufacturing cost of the equipment but also make the system maintenance complex and time-consuming. Therefore, it is particularly important to design a sample rack structure that can achieve rapid and stable height adjustment through simple manual operation. Utility Model Content

[0016] 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.
[0017] Please see Figure 1-3This utility model provides a technical solution: a height-adjustable temperature test chamber sample rack structure, including a test chamber body 1. The test chamber body 1 has several vertically distributed support plates 2 inside its experimental cavity. A sealed door is hinged to the outside of the experimental cavity of the test chamber body 1. Vertically distributed guide frames 3 are welded and fixed to the inner walls of the four corners of the experimental cavity of the test chamber body 1. Horizontally distributed positioning frames 4 are provided between groups of guide frames 3 on the same side. A guide sleeve 5 is welded and fixed to the middle of the outer side of the positioning frame 4. Guide rods 6 are provided on both sides of the bottom of the support plates 2, inserted inside the guide sleeves 5. The connection between the guide rods 6 and the support plates 2 is fixed by welding. Furthermore, a manual quick-adjustment mechanism consisting of a fixed block 7, an adjusting stud 8, and an elastic support 9 is provided on the outer side of the guide sleeve 5. This structure... When in use, the operator can adjust the position of the main body 1 of the test chamber by rotating the adjusting stud 8 within the fixed block 7, thereby pushing or pulling the top of the elastic support 9 relative to the support point of the bearing plate 2. The bearing plate 2 can then move up and down within the guide sleeve 5 via the guide rod 6, achieving rapid height adjustment. Furthermore, the elastic support 9 provides additional support and cushioning for the bearing plate 2 after adjustment, ensuring the sample rack remains stable at any height. This design simplifies traditional complex mechanical or electric drive systems, allowing users to easily adjust the height of the sample rack manually, greatly improving operational convenience and experimental efficiency. It solves the problems of high equipment cost and complex maintenance in existing technologies, while also ensuring stability even with frequent sample height adjustments. Even under extreme conditions, it maintains high efficiency and stable performance, making it ideal for experimental scenarios requiring flexible adjustment of sample height. The solid block 7 is horizontally welded and fixed to the outside of the guide sleeve 5. The adjusting stud 8 is vertically inserted into the solid block 7 via a threaded structure. The lower part of the elastic support 9 is welded and fixed to the top of the solid block 7. The top of the adjusting stud 8 is connected to the bottom inner wall of the upper part of the elastic support 9 via a bearing. The elastic support 9 has a U-shaped structure, and its top is in abutting contact with the bottom of the bearing plate 2. By rotating the adjusting stud 8, the operator can move it up and down along the solid block 7, thereby adjusting the height of the elastic support 9 connected to it via a bearing. The elastic support 9 provides necessary support while... It can also adapt to slight height changes, thus ensuring stable support for the bearing plate 2 at different heights. Both ends of the positioning frame 4 are welded and fixed with sliders, and the inner side of the guide frame 3 is provided with guide grooves that cooperate with the slider structure at the end of the positioning frame 4. Positioning cylinders 10 are welded and fixed to the bottom of both sides of the positioning frame 4, and positioning pins 11 are horizontally inserted inside the positioning cylinders 10. Furthermore, several positioning holes that match the structure of the positioning pins 11 are evenly provided on the inner wall of the guide groove on the inner side of the guide frame 3. With this structure, the operator first moves the positioning frame 4 up and down along the guide frame 3 using the cooperation of the sliders and guide grooves to quickly pre-position the height of the positioning frame 4. Once the positioning frame 4 reaches the required height, the positioning pins 11 are horizontally inserted through the positioning cylinders 10 and into the corresponding positioning holes on the inner wall of the guide groove.This locks the position of the positioning frame 4, ensuring its stability and greatly improving the convenience and efficiency of experimental operations. A rectangular groove 12 is provided at the bottom of the support plate 2, and several strip-shaped balance blocks 13 are located inside the rectangular groove 12. Both ends of the balance blocks 13 are connected to the inner walls of the rectangular groove 12 via limiting guide blocks. This structure allows the operator to adjust the position of the balance blocks 13 within the rectangular groove 12 according to the specifications of the sample placed on the support plate 2. That is, by moving the balance blocks 13, their distribution within the rectangular groove 12 can be adjusted, effectively distributing and optimizing the load distribution on the support plate 2, thereby improving the stability and safety of the entire sample holder.
[0018] Working Principle: When using this adjustable temperature test chamber sample rack structure, the height positions of the two positioning frames 4 are first pre-determined according to experimental requirements. That is, the operator moves the positioning frame 4 up and down along the guide frame 3 by using the sliders at both ends of the positioning frame 4 and the guide groove in the guide frame 3. After quickly adjusting to the required height, the positioning pin 11 is inserted horizontally through the positioning cylinder 10 and into the corresponding positioning hole on the inner wall of the guide groove. This initially locks the position of the positioning frame 4. Next, the operator can adjust the position of the balance block 13 in the rectangular groove 12 according to the specifications of the sample placed on the support plate 2. That is, the load distribution on the support plate 2 is optimized by moving the balance block 13. After completing the above steps, the operator can adjust the position of the adjusting stud 8 in the fixed block 7 by rotating the adjusting stud 8, thereby pushing or pulling the position of the top of the elastic support member 9 relative to the support point of the support plate 2. This allows the support plate 2 to move up and down through the guide rod 6 inside the guide sleeve 5, achieving rapid height adjustment. When the support plate 2 is adjusted to the ideal height, the elastic support member 9 provides additional support for the support plate 2, ensuring that the sample rack remains stable at any height, thus completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
