[0003] The temperature shock test equipment in the prior art generally has only one high-temperature box and one low-temperature box. During the temperature shock test, after the test rack carrying the test product moves from the low-temperature box to the high-temperature box (or from the high-temperature box to the low-temperature box), the low-temperature box is idle, and only one test product can be tested at a time, resulting in energy waste. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem that the temperature shock test equipment in the prior art generally has only one high-temperature box and one low-temperature box. During the temperature shock test, after the test rack carrying the test product moves from the low-temperature box to the high-temperature box (or from the high-temperature box to the low-temperature box), the low-temperature box is in an idle state, and only one test product can be tested at a time, resulting in a waste of energy. A high and low temperature shock test chamber is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high and low temperature impact test box, comprising an installation box and a storage box, wherein the top of the front side of the installation box is rotatably connected to a side sealing door via a hinge, an auxiliary handle is fixedly provided at the middle position of the outer side of the side sealing door, a partition plate is fixedly provided at the middle position of the inner cavity of the installation box, the partition plates are movably inserted with storage boxes along the vertical direction, a top-moving screw is threaded into the side surface of the storage box located at the top of the side surface of the partition plate, and a bottom-moving screw is threaded into the side surface of the storage box located at the bottom of the side surface of the partition plate, and a driving component is provided on the outer side surface of the installation box for driving the two storage boxes to alternately enter the cooling cavity of the installation box.

[0007] Optionally, one end of the top-moving screw away from the side of the partition plate is rotatably connected to the side of the installation box, and one end of the bottom-moving screw away from the side of the partition plate is rotatably connected to the side of the installation box.

[0008] Optionally, the partition plate divides the inner cavity of the storage box into a cooling cavity and a heating cavity, the installation box is fixedly connected to a cooling installation pipe at the top of the cooling cavity, and the installation box is fixedly connected to a heating installation pipe at the top of the heating cavity.

[0009] Optionally, the driving assembly includes a top drive gear, a bottom drive gear, and a switching gear rod, the top drive gear is fixedly connected to the end of the top-moving screw rod, and the bottom drive gear is fixedly connected to the end of the bottom-moving screw rod.

[0010] Optionally, the installation box is fixedly provided with a side protection box on one side of the top drive gear and the bottom drive gear, a vertical plate is fixedly provided on the side of the side protection box, and an electric push rod is fixedly provided on the side of the vertical plate.

[0011] Optionally, the output end of the electric push rod extends from the top of the side guard box, and a switching gear rod is fixedly provided on the output end of the electric push rod, and the switching gear rod is stably engaged with the top drive gear.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. A cooling chamber and a heating chamber are formed in the middle of the installation box of the utility model through a partition plate. The partition plate is movably inserted into two storage boxes for storing experimental products in the vertical direction, and a driving assembly is provided on the sides of the two storage boxes. The driving assembly can make one storage box be in the cooling chamber and the other storage box in the heating chamber at the same time, so as to avoid the cooling chamber or the heating chamber of the installation box being idle. It can effectively solve the problem of temperature shock test equipment in the prior art, which generally has only one high-temperature box and one low-temperature box. During the temperature shock test, after the test rack carrying the test product moves from the low-temperature box to the high-temperature box (or from the high-temperature box to the low-temperature box), the low-temperature box is idle, and only one test product can be tested at a time, resulting in energy waste.
