Most of these simulation devices are test chambers.
[0003] At present, in order to better simulate the natural environment, lighting is often installed inside the test chamber to simulate sunlight, so as to test the service life of parts under sunlight.
[0004] However, this type of lighting is directly installed inside the test chamber through mounting brackets or bolts, and it does not have an adjustment mechanism. As a result, after the position is fixed, the lighting position cannot be adjusted according to later needs to obtain the effect of lighting tests in different positions. For this reason, we propose a sunlight simulation test device for a climate test chamber. Utility Model Content

[0026] A fixed track 2, the fixed track 2 is fixedly connected to the top of the experimental box body 1;
[0027] A sliding sleeve 3, the sliding sleeve 3 is slidably arranged on the outer surface of the fixed rail 2;
[0028] The special-shaped extrusion block 5 is rotatably arranged on the sliding sleeve 3, and the special-shaped extrusion block 5 is used to lock the position of the fixed track 2. The special-shaped extrusion block 5 is composed of a positioning block 501 and an arc block 502 located on one side of the positioning block 501;
[0029] The rod body assembly 9 is arranged at the bottom of the special-shaped extrusion block 5, and the rod body assembly 9 can drive the special-shaped extrusion block 5 to rotate. The bottom end of the sliding sleeve 3 is symmetrically fixedly connected with two limiting arc pieces 10, and the limiting arc pieces 10 can hinder the rotation of the rod body assembly 9; when the sunlight lighting lamp 8 needs to be adjusted, the sliding sleeve 3 is moved along the fixed track 2, so that the sliding sleeve 3 drives the sunlight lighting lamp 8 to move together, and then the rod body assembly 9 is used to drive the special-shaped extrusion block 5 to rotate, so that the arc block 502 rotates along the bottom of the fixed track 2, until the positioning block 501 squeezes the bottom end of the fixed track 2, thereby fixing the sliding sleeve 3 on the fixed track 2, and then the rod body assembly 9 is clamped on the limiting arc piece 10, thereby avoiding abnormal rotation of the rod body assembly 9 due to accidental contact, so that the positioning block 501 no longer squeezes the fixed track 2, so that the sunlight lighting lamp 8 cannot be fixed.
[0030] It should be further explained that a through slot 4 is provided at the bottom end of the sliding sleeve 3, a rotating block 7 is rotatably connected inside the through slot 4, the special-shaped extrusion block 5 is rotatably connected to the through slot 4 via the rotating block 7, and the rod assembly 9 includes a fixed rod 901 fixedly connected to the bottom end of the rotating block 7, a fixed round block 902 fixedly connected to the bottom end of the fixed rod 901, a return spring 903 sleeved on the outer surface of the fixed rod 901 and a movable sleeve 904 located outside the return spring 903; when the rod assembly 9 is required to drive the special-shaped extrusion block 5 to rotate, the movable sleeve 904 is pulled down so that the movable sleeve 904 squeezes the return spring 903 until the movable sleeve 904 is separated from the limiting arc piece 10, and then the rod assembly 9 is rotated so that the rod The component 9 drives the rotating block 7 and its special-shaped extrusion block 5 to rotate, so that the positioning block 501 rotates along the fixed track 2, and until the positioning block 501 is no longer in contact with the fixed track 2, at which time the arc block 502 is located directly below the fixed track 2, and then the sliding sleeve 3 can be moved to change the position of the sunlight lighting lamp 8, and then the rod body component 9 is reversed to rotate the arc block 502 until the positioning block 501 squeezes the fixed track 2 again, thereby fixing the position of the sliding sleeve 3. At this time, the rod body component 9 is in a vertical state, and then the movable sleeve 904 is released, and the reset spring 903 resets and drives the movable sleeve 904 to be inserted between the two limiting arc pieces 10, so that the limiting arc piece 10 limits the rod body component 9.
[0031] Furthermore, the outer contour of the positioning block 501 is set to a smooth arc, the outer contour of the arc block 502 is set to a non-smooth arc, and the radius of the arc block 502 decreases from close to the positioning block 501 to far away from the positioning block 501; a rubber pad 6 is fixedly set on the outer side of the positioning block 501, and the outer surface of the rubber pad 6 is provided with anti-slip texture, and the special-shaped extrusion block 5 is vertically arranged below the fixed track 2; the radius size of the arc block 502 decreases from close to the positioning block 501 to far away from the positioning block 501, so as to facilitate the positioning block 501 to be able to smoothly extrude the bottom of the fixed track 2, and also to facilitate the arc block 502 to contact with the bottom of the fixed track 2, and the positioning block 501 has the same radius everywhere, and combined with the rubber pad 6, it can better extrude the fixed track 2.
[0032] Furthermore, the fixed track 2 is composed of a plurality of connecting rods 201 fixedly connected to the inner wall surface of the experimental box body 1 and a transverse track 202 fixedly connected to the bottom ends of the plurality of connecting rods 201; the sliding sleeve 3 is composed of a fixed sleeve 301 slidably connected to the transverse track 202 and an arc sleeve 302 fixedly connected to the bottom end of the fixed sleeve 301, and the through groove 4 is opened at the bottom end of the arc sleeve 302, and the mounting bracket of the sunlight lighting lamp 8 is fixedly connected to the bottom of the arc sleeve 302; when the sliding sleeve 3 moves along the fixed track 2, it is actually the fixed sleeve 301 that moves along the transverse track 202, and the setting of the arc sleeve 302 is to facilitate the normal rotation of the rod body assembly 9, and the through groove 4 will not hinder the movement trajectory of the special-shaped extrusion block 5.
[0033] The sunlight lighting lamp 8 adopts a high-spectrum bulb and is controlled by the control center of the experimental box body 1. It can control the on and off of the sunlight lighting lamp 8 and the changes in its spectrum, and can also control the degree of lighting of the sunlight lighting lamp 8, thereby simulating the light intensity.
