[0003] A Chinese patent discloses an ultraviolet accelerated aging test chamber (authorization announcement number CN215066035U) that is easy to disassemble and assemble ultraviolet lamps. The patented technology is mainly used to fix the ultraviolet lamps by setting a fixed structure, so as to realize the rapid installation and disassembly of the ultraviolet lamps. The ultraviolet lamps are effectively fixed by the clamping connection between the clamping shaft and the mounting block. Compared with the traditional fixing method of multiple screws, only the two clamping shafts can be driven to move by the rotating parts. The operation is simple and convenient, which makes the disassembly faster, greatly saves the disassembly time, and provides convenience for people.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: since the existing aging test devices use fixed installation of ultraviolet lamps, the irradiation distance and angle between the ultraviolet rays and the test object cannot be adjusted, which reduces the efficiency of the ultraviolet aging test and the accuracy of the test results.

[0008] Preferably, the bottom of the round shell is fixedly connected to a first threaded block, the internal thread of the first threaded block is connected to a first bolt, the surface of the first bolt is slidably connected to a connecting block, and the bottom of the connecting block is fixedly connected to the ultraviolet irradiation device.

[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a UV aging test box, comprising a shell 1, a cabinet door 2 is connected to the front end of the shell 1 through a hinge, a heat insulation board 3 is fixedly connected to the inside of both sides of the shell 1, and an adjustment component 4 for adjustment is installed on the top of the shell 1;

[0024] The adjustment component 4 includes a threaded rod 401 and an extension block 402. The threaded rod 401 is rotatably connected to the top of the outer shell 1. The surface of the extension block 402 is rotatably connected to a round shell 403. An ultraviolet irradiation device 404 is installed at the bottom of the round shell 403. The staff screws the threaded rod 401 downward, and the threaded connection between the threaded rod 401 and the top of the outer shell 1 makes the threaded rod 401 push the ultraviolet irradiation device 404 installed at the bottom of the round shell 403 downward, so that the staff can adjust the distance between the ultraviolet irradiation device 404 and the test object according to the test requirements to perform ultraviolet aging tests, thereby improving the accuracy of the test.

[0025] Reference Figure 3 As shown, in this embodiment: the bottom of the round shell 403 is fixedly connected with the first threaded block 5, the internal thread of the first threaded block 5 is connected with the first bolt 6, the surface of the first bolt 6 is slidably connected with the connecting block 7, the bottom of the connecting block 7 is fixedly connected with the ultraviolet irradiation device 404, and the first bolt 6 is rotatably connected with the connecting block 7, so that the staff can rotate the ultraviolet irradiation device 404 to the specified position, and then tighten the first bolt 6 into the first threaded block 5 to fix the position of the ultraviolet irradiation device 404, so as to adjust the irradiation angle of the ultraviolet irradiation device 404 to the test object, so that the ultraviolet irradiation device 404 can irradiate the corners of the test object, and prevent the ultraviolet irradiation device 404 from having an irradiation dead angle to reduce the accuracy of the test structure.

[0026] Reference Figure 3 As shown, in this embodiment: the surface of the connecting block 7 is slidably connected with an anti-skid pad 8, and the material of the anti-skid pad 8 is rubber. By sleeved on the surface of the connecting block 7 with the material of rubber, the friction between the first bolt 6 and the connecting block 7 is increased to prevent the first bolt 6 from slipping and loosening after being tightened, so that the first bolt 6 and the connecting block 7 fix the ultraviolet irradiation device 404 more firmly.

[0027] Reference Figure 3As shown, in this embodiment: the right side of the extension block 402 is fixedly connected with a second threaded block 9, and the inner wall of the second threaded block 9 is threadedly connected with a second bolt 10, and the staff rotates the round shell 403 to adjust the horizontal irradiation angle of the ultraviolet irradiation device 404 to cooperate with the first bolt 6 and the connecting block 7, and the staff screws down the second bolt 10 to abut against the bottom of the round shell 403 to fix the rotation angle of the ultraviolet irradiation device 404, thereby increasing the flexibility of the adjustment device and increasing the irradiation angle of the ultraviolet irradiation device 404.

[0028] Reference Figure 3 As shown, in this embodiment: a plurality of raised blocks 11 are fixedly connected to the top of the circular shell 403. By arranging a plurality of raised blocks 11 on the top of the circular shell 403, the friction between the bottom of the second bolt 10 and the circular shell 403 is increased, so that the rotation angle of the circular shell 403 by the second bolt 10 is fixed more firmly.

[0029] Reference Figure 3 As shown, in this embodiment: a slide groove 12 is provided on the surface of the extension block 402, and a round ball 13 is slidably connected to the inner wall of the slide groove 12. Through the sliding connection between the round ball 13 and the slide groove 12, the round ball 13 can contact the inner wall of the round shell 403 for rotation, thereby reducing the friction generated by the rotation of the round shell 403 and the extension block 402 and causing wear, thereby increasing the service life of the device.

[0030] Reference Figure 2 As shown, in this embodiment: the material of the heat insulation board 3 is asbestos cast in one piece, and the heat insulation board 3 arranged on both sides of the shell 1 makes the shell 1 have good heat insulation and insulation effect, which prevents the heat generated by the ultraviolet irradiation device 404 from being transferred to the shell 1, causing the shell 1 to be too high in temperature and cause burns to the staff, and at the same time prevents the temperature loss inside the shell 1 from reducing the test efficiency.

[0031] The practical working principle of the present invention is as follows: the staff screws the threaded rod 401 downwards, and the threaded connection between the threaded rod 401 and the top of the shell 1 is used to make the threaded rod 401 push the ultraviolet irradiation device 404 installed at the bottom of the round shell 403 downwards, so that the staff can adjust the distance between the ultraviolet irradiation device 404 and the test object according to the test requirements to conduct ultraviolet aging tests, thereby improving the accuracy of the test; the rotational connection between the first bolt 6 and the connecting block 7 allows the staff to rotate the ultraviolet irradiation device 404 to a specified position, and then screw the first bolt 6 into the first threaded block 5 to tighten it, fixing the position of the ultraviolet irradiation device 404, thereby adjusting the irradiation angle of the ultraviolet irradiation device 404 to the test object, so that the ultraviolet irradiation device 404 can irradiate the corners of the test object, preventing the ultraviolet irradiation device 404 from having an irradiation dead angle that reduces the accuracy of the test structure; the anti-slip pad 8 is made of rubber and is sleeved on the surface of the connecting block 7, thereby increasing the friction between the first bolt 6 and the connecting block 7, thereby preventing the first bolt 6 from being tightened After the thread is loosened, the first bolt 6 and the connecting block 7 fix the ultraviolet irradiation device 404 more firmly. The staff rotates the round shell 403 to adjust the horizontal irradiation angle of the ultraviolet irradiation device 404 for use with the first bolt 6 and the connecting block 7, and the staff screws down the second bolt 10 to abut the bottom of the round shell 403 to fix the rotation angle of the ultraviolet irradiation device 404, thereby increasing the flexibility of the adjustment device and the irradiation angle of the ultraviolet irradiation device 404. The ball 13 is slidably connected with the slide groove 12 so that the ball 13 can contact the inner wall of the round shell 403 for rotation, thereby reducing the friction caused by the rotation of the round shell 403 and the extension block 402 and causing wear, thereby increasing the service life of the device. The heat insulation plates 3 are arranged on both sides of the outer shell 1, so that the outer shell 1 has a good heat insulation effect, thereby preventing the heat generated by the ultraviolet irradiation device 404 from being transferred to the outer shell 1, causing the outer shell 1 to be too high in temperature and cause burns to the staff, and at the same time preventing the temperature loss inside the outer shell 1 from reducing the test efficiency.
