Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, in particular to a high and low temperature continuous change test box. Background Art

[0002] The high and low temperature continuous change test chamber is an environmental testing equipment 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] At present, when conducting high and low temperature continuous change tests on large equipment, the large equipment to be tested is usually fixed to a transport rack, and then the transport rack is pushed into the interior of the test chamber body to move the large equipment into the test chamber body, so as to test the large equipment. However, the current transport rack is not easy to position after entering the interior of the test chamber body. During the test, the transport rack may move left and right and may collide with the inner wall of the test chamber body, thereby damaging structures such as sensors arranged on the inner wall of the test chamber body, affecting the test effect. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a high and low temperature continuously changing test chamber in response to the above-mentioned defects, which not only facilitates the movement of the transport rack equipped with large equipment into the test chamber body and positions it, but also can adapt to transport racks of different widths.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a high and low temperature continuously changing test chamber, including a test chamber body, a chamber door is provided on one side of the test chamber body, and a support part for supporting and limiting the transport rack is provided inside the test chamber body. The support part includes two support plates arranged at intervals along the width direction of the test chamber body, and each support plate is provided with a receiving groove for accommodating a slider along its length direction. An adjustment component for adjusting the distance between the two support plates is provided inside the test chamber body.

[0006] Explanation: Sliders are arranged in parallel on both sides of the bottom of the transport rack.

[0007] Compared with the existing technology, the beneficial effects of this solution are: in the initial state, the box door on one side of the test box body is opened, the large equipment is placed on the transport rack, and then the transport rack is moved to the support part located inside the test box body, so that the sliders at the bottom of the transport rack are respectively located in the accommodating grooves on the two support plates and slide with them. The large equipment is moved and positioned into the test box body through the cooperation of the accommodating grooves and the sliders. The structure is reasonable and can prevent the transport rack from moving inside the test box body and colliding with the inner wall of the test box body during the test, causing damage to structures such as the temperature sensor located on the inner wall of the test box body, thereby avoiding affecting the test results; according to the different width sizes of different transport racks, the distance between the two support plates is adjusted by adjusting the assembly, so that the support part can adapt to transport racks of different width sizes, and the adaptability range is large.

[0008] As a preferred embodiment of the present invention, an auxiliary part is obliquely provided on one side of the test box body close to the box door, the auxiliary part is used to assist the transport rack to enter the test box body, and the adjustment component is provided on the auxiliary part.

[0009] The beneficial effect of this solution is that when the transport rack is moved into the test chamber body, the transport rack first passes through the inclined auxiliary part and then moves to the support part, which facilitates the movement of the transport rack equipped with large equipment into the test chamber body and saves manpower.

[0010] As a preferred embodiment of the present invention, the auxiliary part includes an auxiliary plate arranged at an angle and a horizontally arranged mounting block, the mounting block is provided with a first slide groove for slidingly cooperating with the support plate, and a second slide groove corresponding to the position of the first slide groove is provided on the inner wall of the test box body away from the box door, the side of the support plate away from the adjustment component is slidably cooperating with the second slide groove, and the adjustment component is arranged on the mounting block.

[0011] The beneficial effects of this solution are as follows: both sides of the support plate are respectively located in the first slide groove and the second slide groove and slideably cooperate with them, and the movement of the support plate is guided by the first slide groove and the second slide groove.

[0012] As a preferred embodiment of the present invention, the mounting block is provided with a first connecting hole connected to the first slide groove, and each support plate is provided with a second connecting hole on one side located in the first slide groove. The adjustment assembly includes a bidirectional screw rod threadedly connected to the first connecting hole and the second connecting hole, and the two second connecting holes are respectively located on threads of different rotation directions on the bidirectional screw rod.

[0013] The beneficial effect of this solution is that the two support plates are moved toward or away from each other by rotating the bidirectional screw rod, thereby adjusting the distance between the two support plates to adapt to transport racks of different widths.

[0014] As a preferred embodiment of the present invention, the upper side of each support plate is higher than the upper side of the mounting block, and the bottom wall of the accommodating groove is flush with the upper side of the mounting block.

[0015] The beneficial effects of this solution are as follows: in the process of moving the transport rack into the interior of the test chamber body, the transport rack is first moved along the auxiliary plate to the mounting block. If the bottom wall of the accommodating groove is higher than the upper side of the mounting block, it is inconvenient to move the slider at the bottom of the transport rack into the accommodating groove. The bottom wall of the accommodating groove is flush with the upper side of the mounting block, which facilitates the direct movement of the slider into the accommodating groove. Since the upper side of the support plate is higher than the upper side of the mounting block, that is, the two side walls of the accommodating groove are higher than the upper side of the mounting block, after the slider moves to the accommodating groove, the two side walls of the accommodating groove can be used to limit the slider to prevent the transport rack from moving along the width direction of the test chamber body.

[0016] As a preferred embodiment of the present invention, the support portion further comprises a plurality of support frames spaced apart on the lower side of the support plate, and a plurality of third sliding grooves for slidingly cooperating with the support frames are provided on the inner bottom side of the test box body.

[0017] The beneficial effects of this solution are: by providing multiple support frames on the lower side of the support plate, further supporting the transport frame located above the support plate is provided. Compared with directly contacting the support frame with the bottom side of the interior of the test box body, the support plate is connected to the bottom side of the interior of the test box body by slidingly cooperating with the support frame and the third slide groove, which not only reduces the contact area and thus reduces friction, but also makes the connection between the support plate and the test box body more stable.
