Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, in particular to a load-bearing frame for a temperature change test box. Background Art

[0002] A temperature change test chamber is an environmental testing device used to simulate the temperature change conditions that a product may encounter during actual use. This test chamber can provide continuous temperature changes, from low temperature to high temperature or from high temperature to low temperature, to evaluate the temperature resistance and reliability of the product.

[0003] When conducting a temperature change test, the sample is first placed on a carrier located inside the test chamber body, and then the chamber door is closed for testing. However, existing carriers are usually fixed inside the test chamber body and the spacing cannot be adjusted according to the specific size of the sample, thereby failing to effectively utilize the space. Moreover, since the carriers are fixed, the sample may be unevenly heated during the test, affecting the test results. Utility Model Content

[0004] The technical problem to be solved by the present invention is that, in view of the above-mentioned defects, a carrier rack for a temperature change test chamber is provided, which can not only adjust the spacing of the placement plates according to the specific size of the sample and make rational use of the space, but also drive the rotating rack to rotate during the test, so that the sample is heated evenly and the test effect is better.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a carrier frame for a temperature change test chamber, including a rotating frame located inside the test chamber body, the rotating frame including a top plate, a bottom plate and a plurality of connecting plates located between the top plate and the bottom plate, a plurality of position-adjustable placement plates are arranged at intervals along the vertical direction on the connecting plates, the placement plates are used to place samples, and a driving mechanism for driving the rotating frame to rotate is provided in the test chamber body.

[0006] Compared with the existing technology, the beneficial effects of this solution are: when testing the sample, the driving mechanism drives the rotating frame to rotate, thereby driving the sample placed on the rotating frame to rotate, so that the sample is heated evenly, obtaining better test results, and it is convenient to observe from the observation window; when placing the sample on the placement plate, the distance between the two adjacent placement plates can be adjusted according to the specific size of the sample. After the distance is adjusted to the appropriate position, the box door is closed and the test is carried out. The distance between the placement plates is adjustable, which can not only adapt to samples of different sizes, but also limit the sample by adjusting the spacing between the two adjacent placement plates to contact the sample or have a small gap, thereby preventing the sample from falling during rotation.

[0007] As a preferred embodiment of the present invention, the top plate, bottom plate and placement plate are all disc-shaped, and the inner side of each connecting plate is arc-shaped, and its curvature is the same as the curvature of the outer circular surface of the placement plate.

[0008] The beneficial effects of this solution are as follows: compared to setting the top plate, bottom plate and placement plate in a square shape, setting the top plate, bottom plate and placement plate in a disc shape makes it easier for the driving mechanism to drive the rotating frame to rotate, avoiding interference during rotation, and the inner side of the connecting plate is an arc with the same curvature as the outer circular surface of the placement plate, which makes it easier to install the placement plate on the connecting plate.

[0009] As a preferred embodiment of the present invention, a guide bar is provided on the inner side of each connecting plate, a through groove is provided on the outer circular surface of the placement plate for slidingly cooperating with the guide bar, and a receiving groove is provided on the two opposite side walls of the through groove, and a positioning component is provided in the receiving groove for positioning the placement plate after sliding.

[0010] The beneficial effects of this solution are as follows: the position of the placement plate is adjusted by cooperating with the through groove and the guide bar; the guide bar guides the movement of the placement plate; the placement plate is positioned after movement by the positioning assembly arranged in the accommodating groove to prevent it from moving up and down along the guide bar during the rotation of the first rotating frame or the second rotating frame, causing the sample to fall from the placement plate.

[0011] As a preferred embodiment of the present invention, the positioning assembly includes a compression spring located in a receiving groove on one side and connected to its side wall, and a slider located at the other end of the compression spring. The slider can slide with both receiving grooves. A plurality of connecting holes are evenly spaced along the vertical direction on the guide bar, and the size of the slider matches the size of the connecting hole.

[0012] The beneficial effects of this solution are as follows: in the initial state, the slider passes through the connecting hole and extends into the receiving groove on the other side. When the position of the placement plate needs to be adjusted, the slider is withdrawn from the connecting hole and returned to the receiving groove provided with a compression spring, and then the placement plate is moved along the guide bar. After the position is determined, the slider is driven by the compression spring to slide along the receiving groove and pass through the connecting hole at another position again, and enter the receiving groove without a compression spring, thereby completing the adjustment and positioning of the placement plate.

[0013] As a preferred embodiment of the present invention, an arc-shaped hole communicating with the side receiving groove is opened on the upper side of the placement plate, and a pull rod extending out of the arc-shaped hole and slidable along the upper side of the slider is provided.

[0014] The beneficial effects of this solution are as follows: before adjusting the position of the placement plate, pull the pull rod with your hand to drive the slider to withdraw from the connecting hole and return to the accommodating groove provided with a compression spring, and then move the placement plate along the guide bar. After determining the position, no longer pull the pull rod. Driven by the compression spring, the slider slides along the accommodating groove and passes through the connecting hole at another position again. Compared with directly pulling the slider, it is more convenient to operate by pulling the pull rod to move the slider.

[0015] As a preferred embodiment of the present invention, support parts are respectively provided on both sides of the interior of the test box body, and two support frames are provided in each support part. The support frames include a connecting column arranged on the inner side of the test box body and an arc-shaped connecting block located in front of the connecting column. The curvature of the inner side of the connecting block is the same as the curvature of the outer circular surface of the top plate and the bottom plate, and the two fit together.

[0016] The beneficial effects of this solution are as follows: the inner side of the arc-shaped connecting block fits with the outer sides of the top plate and the bottom plate, and supports the rotating frame through the support part, avoiding connecting the rotating frame to the test box body only by the driving mechanism, and also avoiding affecting the rotation of the rotating frame.
