Description

Technical Field

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

[0002] A high and low temperature test chamber is a device used to test the performance and reliability of products and materials under high and low temperature environments. It is widely used in electronics, electrical engineering, automotive, aerospace, shipbuilding, weaponry, scientific research institutions, and universities to test the performance indicators of various product components and materials under high and low temperature (alternating) cyclic changes.

[0003] Existing high and low temperature test chambers often require comprehensive testing of components of varying shapes and materials. However, due to the differences in component size and material, their heating conditions also vary significantly, often leading to deviations in test results and compromising accuracy. Furthermore, the constantly changing internal temperature of the test chamber makes it difficult for personnel to reach inside and retrieve components, undoubtedly reducing testing efficiency and impacting the work process. Therefore, we propose a high and low temperature test chamber to address the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high and low temperature test chamber to address the problem mentioned in the background art: existing high and low temperature test chambers often require comprehensive testing of components of various shapes and materials during the testing process. However, due to the different sizes and materials of the components, their heating conditions vary greatly, which often leads to deviations in the test results and makes it difficult to guarantee accuracy. Furthermore, the constantly changing internal temperature of the test chamber makes it difficult for personnel to reach inside and remove components, which undoubtedly reduces testing efficiency and affects the work process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high and low temperature test chamber includes a test chamber, a cover is provided on one side of the test chamber, a movable plate is provided inside the test chamber, a motor rotating component is provided at the bottom of the test chamber, a movable buckle is provided on the top of the cover, two pull rods are symmetrically provided at both ends of the cover near the test chamber, and a rotating disk component is provided on the upper surface of the movable plate.

[0007] The rotating disk component includes a mounting disk, the bottom of which is fixedly connected to a triangular locking pin through a movable plate. The vertical projection of the triangular locking pin is an isosceles triangle.

[0008] Furthermore, the lid includes a cover body, a handle is fixedly connected to one side of the cover body, the bottom of the cover body is rotatably connected to the test chamber, and the movable plate is slidably connected to both ends of the inner side of the test chamber.

[0009] Furthermore, one end of the movable buckle is rotatably connected to the cover and is movably engaged with the test chamber; one end of each of the two pull rods is rotatably connected to both ends of the cover, and the other end of each pull rod is rotatably connected to both ends of the upper surface of the movable plate.

[0010] Furthermore, the bottom of the mounting plate is rotatably connected to the movable plate.

[0011] Furthermore, the motor rotating component includes a motor, and the output end of the motor is fixedly connected to a locking pin and a locking block through the test chamber. The motor is fixedly connected to the test chamber, and the locking pin and the locking block are movably engaged with a triangular locking pin.

[0012] Furthermore, multiple heating tubes are fixedly connected at uniform intervals around the center inside the test chamber, and multiple cooling tubes are spaced apart between the multiple heating tubes, with the multiple cooling tubes fixedly connected to the test chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a motor to rotate a top rotating disk, which in turn rotates the high and low temperature test components. This allows components of different sizes and materials to be heated more effectively, avoiding uneven heating that could lead to inaccurate test results.

[0015] This invention allows the cover to rotate by pulling the handle, which in turn drives two levers to pull out the movable plate, thereby removing the rotating disk component, facilitating the removal of parts and improving testing efficiency. Attached Figure Description
