[0001] This utility model relates to the field of test chamber technology, specifically to a high and low temperature test chamber. Background Technology

[0002] High and low temperature test chambers are testing equipment used to simulate extreme temperature environments. They are widely used in electronics, automotive, aerospace, materials, and scientific research fields. Through a precise temperature control system, they can generate high or low temperature environments within the chamber and achieve rapid temperature changes and long-term constant temperature testing. This equipment is mainly used to evaluate the performance, reliability, and adaptability of products under temperature stress, such as aging tests of components and verification of the cold and heat resistance of products. It has high stability, uniform temperature distribution, and programmable control functions, making it an indispensable key instrument in product quality control and R&D processes.

[0003] However, most existing high and low temperature test chambers use trays to place test materials into the chamber for high and low temperature testing. However, due to the diversity of test materials, the types and sizes of test materials are different. When using trays to carry test materials into the test chamber, interference may occur between the test materials and the trays located above due to their large size, making it impossible to conduct multiple sets of tests simultaneously.

[0004] Therefore, there is an urgent need for a high and low temperature test chamber that can adjust the placement height according to the test materials. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this application provides a high and low temperature test chamber that uses a pallet to support the pallet. By adjusting the height of the pallet, the installation height of the pallet can be changed, increasing or decreasing the distance between two adjacent pallets, expanding or decreasing the accommodating groove between two adjacent pallets, preventing large-volume test materials from interfering with the upper pallet, satisfying the simultaneous testing of multiple sets of materials, and suitable for the use of test materials of different volumes, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high and low temperature test chamber includes: a chamber body, the inner wall of which is provided with several sets of symmetrically distributed convex plates, and an adjustment assembly is provided above the convex plates. The adjustment assembly includes a support plate, which is located above the convex plates.

The two ends of the support plate are respectively engaged with the upper end faces of two support plates located on both sides.

[0007] Preferably, a threaded hole is provided on the upper end face of the convex plate at the position corresponding to the threaded rod, and the threaded rod is threadedly installed inside the threaded hole.

[0009] Preferably, the inner cavity of the box is provided with a receiving groove between two adjacent trays.

[0010] Preferably, the outer wall of the threaded rod is provided with limit nuts at both the upper and lower ends of the convex plate. The two limit nuts are threaded onto the outer wall of the threaded rod and are respectively attached to the upper and lower end faces of the convex plate.

[0011] Preferably, the end of the threaded rod located below the convex plate is provided with a wheel for driving its rotation.

[0012] Preferably, an annular baffle is provided at one end of the positioning slide rod located below the convex plate, and the diameter of the annular baffle is larger than the inner diameter of the sliding hole.

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Combination Figures 1-4 As shown in this embodiment, a high and low temperature test chamber has several sets of symmetrically distributed protruding plates 11 on the inner wall of the chamber body 1. An adjustment component 2 is provided above the protruding plates 11. The adjustment component 2 includes a support plate 21, which is located above the protruding plates 11. The two ends of the tray carrying the test material can be respectively engaged with the upper surfaces of the two support plates 21 located on both sides, and the tray can be placed in the high and low temperature test chamber to realize the high and low temperature test of the test material.

[0018] In this embodiment, a threaded rod 23 is provided on the lower end face of the tray 21. The other end of the threaded rod 23 is threadedly installed inside the convex plate 11 and extends to its lower part. The tray 21 can move up and down above the convex plate 11 by rotating the threaded rod 23. By driving the threaded rod 23 upward in the threaded hole 112 on the convex plate 11, the threaded rod 23 in the displacement pushes the tray 21 to move upward on the convex plate 11, reducing the receiving groove between the tray and the upper tray that is engaged on the tray 21, reserving space for the test material in the lower tray, and meeting the use of test materials with larger volume.

[0019] In this embodiment, when testing a large volume of test material, the threaded rod 23 can be driven in the reverse direction to move downward in the threaded hole 112 on the convex plate 11. The threaded rod 23, in its displacement, pulls the tray 21 downward above the convex plate 11, expanding the receiving groove between it and the upper tray. This prevents the large volume of test material from interfering with the upper tray, allowing for simultaneous testing of multiple sets of materials. This method is suitable for the use of test materials of different volumes.

[0020] In this embodiment, the lower end face of the support plate 21 is provided with positioning slide rods 22 on both sides of the threaded rod 23. The upper end face of the convex plate 11 is provided with a sliding hole 111 at the position corresponding to the positioning slide rod 22. The positioning slide rod 22 is slidably installed inside the sliding hole 111. The support plate 21 moves up and down above the convex plate 11 through the cooperation of the positioning slide rod 22 and the sliding hole 111. At the same time, the positioning slide rod 22 limits the position of the support plate 21 to prevent the support plate 21 from rotating with the threaded rod 23. This avoids the situation where the position of the support plate 21 cannot be adjusted due to the rotation of the support plate 21 with the threaded rod 23, and ensures the position adjustment of the support plate 21.

[0021] In this embodiment, the outer wall of the threaded rod 23 is provided with limit nuts 24 at both the upper and lower ends of the convex plate 11. The two limit nuts 24 are threaded onto the outer wall of the threaded rod 23 and are respectively close to the upper and lower end faces of the convex plate 11. The two limit nuts 24 can be tightened on the upper and lower end faces of the convex plate 11 to limit the position of the threaded rod 23, prevent the threaded rod 23 from rotating, and avoid the situation where the position of the support plate 21 is offset due to the rotation of the threaded rod 23. This realizes the limiting of the threaded rod 23 after the position is adjusted and improves the stability of the support plate 21.

[0022] In this embodiment, an annular baffle 221 is provided at one end of the positioning slide rod 22 located below the convex plate 11. The diameter of the annular baffle 221 is larger than the inner diameter of the sliding hole 111. The annular baffle 221 can be threaded onto the outer wall of the positioning slide rod 22. The position of the positioning slide rod 22 is limited by the annular baffle 221 to prevent the positioning slide rod 22 from falling off the convex plate 11 and to ensure the use of the positioning slide rod 22.

[0023] In this embodiment, a rotating wheel 231 for driving the threaded rod 23 to rotate is provided at one end of the threaded rod 23 located below the convex plate 11. By threading the rotating wheel 231 onto the end of the threaded rod 23, the rotating wheel 231 drives the threaded rod 23 to rotate, allowing the threaded rod 23 to move up or down in the threaded hole 112, thereby driving the threaded rod 23.

[0024] The working principle of this utility model is as follows: The high and low temperature test chamber proposed in this application sets a convex plate 11 on the inner wall of the chamber body 1, and uses a rotating wheel 231 to drive the threaded rod 23 to move upward or downward in the threaded hole 112. Then, the threaded rod 23 pushes or pulls the pallet 21 to move upward or downward above the convex plate 11, thereby changing the installation height of the pallet, increasing or shortening the distance between two adjacent pallets, expanding or shrinking the accommodating groove between two adjacent pallets, preventing large-volume test materials from interfering with the upper pallet, satisfying the simultaneous testing of multiple sets of materials, and suitable for the use of test materials of different volumes.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
