Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.

[0023] like Figure 1 and Figure 2 As shown, this embodiment discloses an aging test device, which includes a layer assembly 10 and a main frame 20, specifically as follows:

[0024] like Figure 2 and Figure 3 As shown, the layer plate assembly 10 includes a plurality of layer plates 11 arranged on the main frame 20 along the height direction, and the plurality of layer plates 11 are arranged at intervals up and down, and the external workpiece to be tested (not shown) is set on the layer plate 11, wherein the layer plate 11 is formed by bending and welding steel plates, and a plurality of screw slots are provided on the layer plate 11, and the tooling fixture for installing the workpiece can be fixed on the layer plate 11 by the cooperation of screws and screw slots.

[0025] like Figure 2 As shown, the main frame 20 is welded with stainless steel profiles; along the length direction of the layer plate 11 (that is, the second horizontal direction), groove structures are provided on both sides of the main frame 20, and each layer plate 11 has a groove structure on both sides to cooperate with it, which can facilitate the adjustment of the position of the layer plate 11.

[0026] like Figure 4 and Figure 5As shown, the groove structure includes a first slide groove 21, a second slide groove 22, a roller 23 and a limit pin 24. The first slide groove 21 is opened along the first horizontal direction, and the first horizontal direction and the second horizontal direction intersect vertically in the horizontal plane; the second slide groove 22 includes a first sub-slot segment 22a and a second sub-slot segment 22b that are connected to each other. The length direction of the first sub-slot segment 22a is configured as the height direction, and the depth direction (that is, the length direction) of the second sub-slot segment 22b forms an angle θ with the length direction of the first sub-slot segment 22a. The angle θ is less than 90 degrees, for example, 40 degrees to 80 degrees, and preferably 60 degrees. or 70 degrees; the roller 23 is rotatably arranged on the side of the layer plate 11, and the outer circumferential surface of the roller 23 can roll in contact with the inner wall surface of the first slide groove 21, so that the roller 23 can roll in the first slide groove 21, wherein the axial configuration of the roller 23 is the second horizontal direction; the limit pin 24 is arranged on the side of the layer plate 11, wherein the limit pin 24 and the roller 23 are respectively located at the two ends of the side of the layer plate 11, the axial configuration of the limit pin 24 is the second horizontal direction, and the limit pin 24 is arranged in the first sub-groove segment 22a or the second sub-groove segment 22b of the second slide groove 22 along the second horizontal direction.

[0027] like Figure 4 and Figure 5 As shown, when the posture of the layer plate 11 needs to be adjusted to an inclined state, the layer plate 11 slides in the first slide groove 21 with the help of the roller 23, so that the end of the layer plate 11 provided with the limit pin 24 is lifted upward, and the limit pin 24 first slides upward in the first sub-groove section 22a. When it reaches the predetermined position, the limit pin 24 is pushed into the second sub-groove section 22b. The position of the limit pin 24 is limited by the second sub-groove section 22b, and the layer plate 11 can be maintained in an inclined posture.

[0028] It is understandable that if Figure 4 and Figure 5 As shown, the inclination angle of the layer plate 11 relative to the horizontal plane is related to the height position of the second sub-groove segment 22b. In order to be able to meet the needs of the layer plate 11 to achieve multiple angles of inclination, the number of the second sub-groove segments 22b is set to multiple, and the multiple second sub-groove segments 22b are distributed along the height direction, and each second sub-groove segment 22b is connected to the first sub-groove segment 22a. In this way, the limit pin 24 can be selectively pushed into different second sub-groove segments 22b according to actual needs, thereby adjusting the inclination angle of the layer plate 11.

[0029] like Figure 4 and Figure 5As shown, the inner width of the first chute 21 is equal to the outer diameter of the roller 23, which ensures the stability of the roller 23 in the first chute 21 and allows the roller 23 to roll only in the length direction of the first chute 21. A channel steel 25 is provided on the main frame 20, and the length direction of the channel steel 25 is configured as a first horizontal direction. The inner recessed space of the channel steel 25 is configured as the first chute 21. By selecting the channel steel 25 as the forming component of the first chute 21, the structural material is easily available.

[0030] like Figure 4 and Figure 5 As shown, the bottom end of the first sub-groove segment 22a is at the same horizontal height as the channel steel 25, that is, the lowest position of the limit pin 24 in the first sub-groove segment 22a is the same as the height position of the channel steel 25. In this way, the limit pin 24 on the layer plate 11 can automatically fall back to the lowest end of the first sub-groove segment 22a after being pushed out of the second sub-groove segment 22b, and the layer plate 11 can be flipped back to a horizontal state.

[0031] In some preferred embodiments, Figure 6 As shown, the aging test device further includes a moving component 30 ; the moving component 30 is disposed at the lower end of the main frame 20 and is used to enable the main frame 20 to move on the ground.

[0032] The moving assembly 30 includes two fixed wheels 31 and two universal wheels 32. The two fixed wheels 31 and the two universal wheels 32 are respectively arranged at four corner positions below the main frame 20 to enable the main frame 20 to roll on the ground.

[0033] In some preferred embodiments, Figure 6 As shown, the aging test device further includes a guide assembly 40 , which is disposed on the lower surface of the main frame 20 and is used to guide the movement of the main frame 20 .

[0034] The guide assembly 40 includes two guide plates 41, which are arranged relative to each other along a first horizontal direction on the lower surface of the main frame 20. A guide channel 40a is formed between the two guide plates 41. The guide channel 40a extends along a second horizontal direction and can cooperate with a track or guide bearing within the aging chamber to guide the movement of the main frame 20, thereby defining the movement direction of the main frame 20. One end of the guide channel 40a is configured as a bell mouth 40b, which facilitates the insertion of the track or guide bearing into the guide channel 40a.

[0035] In some preferred embodiments, Figure 6As shown, the aging test device also includes a positioning component 50; the positioning component 50 includes a positioning plate 51 and a docking copper plate 52. Along the second horizontal direction, the positioning plate 51 is arranged on one side of the main frame 20, and the positioning plate 51 is located at the front end of the forward direction of the main frame 20. A positioning hole 511 is provided on the positioning plate 51, and the docking copper plate 52 is arranged on the main frame 20, and the docking copper plate 52 and the positioning plate 51 are located on the same side of the main frame 20. The docking copper plate 52 is used to electrically connect with the external structure.

[0036] When the main frame 20 is pushed forward, the positioning holes 511 on the positioning plate 51 are precisely positioned with the positioning pins of the aging room. The main frame 20 continues to be pushed forward to complete the docking of the probe and the docking copper plate 52. Then, the main frame 20 is limited by the limiting mechanism in the aging room to carry out the test.
