[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high-temperature accelerated aging temperature test chamber of the utility model comprises a temperature test chamber 1, a plurality of shells 2 are installed inside the test chamber of the temperature test chamber 1, one end of the shell 2 forms an operation port 7 connected to the test chamber, a plurality of base plates 3 for placing the products to be tested are arranged inside the shell 2, one end of the base plates 3 protrudes to form a moving part 8, the moving parts 8 extend into the operation port 7, and are vertically provided with fixing holes 11, pull rods 4 are installed in the vertically opposite fixing holes 11, and a driving mechanism for driving the base plates 3 to move up and down is installed on the upper end of the pull rods 4.

[0022] In this embodiment, the driving mechanism includes a plurality of longitudinal plates 5 and a plurality of cylinders 6. A plurality of fixed blocks 9 are installed on the top surface of each pull rod 4, and an extension rod 12 is installed on the top surface of the remaining pull rods 4. One longitudinal plate 5 is longitudinally installed on the plurality of fixed blocks 9, and another longitudinal plate 5 is longitudinally installed on the plurality of extension rods 12. The longitudinal plates 5 are staggered one above and one below, and the piston rods of the cylinders 6 are all installed on the top surface of the longitudinal plates 5, and the cylinder bodies of the cylinders 6 are all installed on the top surface of the test cavity.

[0023] In this embodiment, a plurality of positioning holes are provided on the bottom surface of the bottom plate 3 , and positioning rods 13 are provided in each of the positioning holes. The lower ends of the positioning rods 13 are installed on the bottom surface inside the housing 2 .

[0024] In this embodiment, the top surface of the bottom plate 3 is arranged to protrude from the top surface of the housing 2, thereby preventing the product to be tested from contacting the housing.

[0025] In this embodiment, a space for placing the product to be tested is formed between the shells 2, wherein the number of the shells can be adjusted according to the height of the product to be tested, so that the product to be tested can be smoothly placed inside the shells.

[0026] In this embodiment, the bottom plates 3 are arranged without contact with each other, so that the high-temperature gas can contact the bottom surface of the product to be tested along the gaps between the bottom plates.

[0027] When in use, the product to be tested can be placed directly on the bottom plate. When testing, the cylinder can be started. The two cylinders are started one after the other, and the piston rods of the cylinders are reciprocated. The movement of the piston rod drives the longitudinal plate, and the movement of the longitudinal plate drives the fixed block. The movement of the fixed block drives the pull rod and the corresponding bottom plate, so that the bottom plate moves downward along the positioning rod, so that this part of the bottom plate is moved away from the bottom of the product to be tested, and the external high-temperature gas can contact the bottom surface of the product to be tested after the movement. After starting another cylinder, the piston rod of the previous cylinder will retract, so that the bottom plate that was previously moved downward moves upward and contacts the bottom surface of the product to be tested, and the start of the other cylinder can drive the remaining bottom plate to move downward, so that another part of the bottom surface of the product to be tested is exposed, so that the internal high-temperature gas can contact it, and the bottom surface of the product to be tested is continuously exposed through the continuously moving bottom plate to ensure that the internal high-temperature gas contacts the bottom surface of the product to be tested, thereby increasing the heating efficiency and uniformity to ensure the quality of the test.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
