[0019] Preferably, the arc surface of the clamping rod is rotatably connected to a rotating plate, and the arc surface of the fixing ring is fixedly connected to a blocking rod.

[0020] The effect achieved by the above components is that after the blocking rod is located between the rotating plate and the fixed frame, the blocking rod reaches a position to limit the rotating plate, thereby preventing the clamping rod from affecting the rotation of the rotating frame due to the tension of the spring.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] like Figure 1-4 As shown, the utility model provides an ultraviolet aging tester, including a test box 1, a controller 2 is installed on the upper surface of the test box 1, an ultraviolet lamp 3 is detachably installed on the inner wall of the test box 1, the ultraviolet lamp 3 is electrically connected to the controller 2, a limiting structure 4 is provided on the inner wall of the test box 1, and an auxiliary structure 5 is provided on the arc surface of the fixing ring 401.

[0032] The specific arrangement and function of the limiting structure 4 and the auxiliary structure 5 will be described in detail below.

[0033] like Figure 2 and Figure 3 As shown, the limiting structure 4 includes a fixing ring 401, which is fixedly connected to the test box 1, and the inner wall of the fixing ring 401 is rotatably connected to a rotating frame 402, and the surface of the rotating frame 402 is fixedly connected to a placing plate 403, and the surface of the placing plate 403 is slidably connected to a sliding frame 404, and the surface of the sliding frame 404 is fixedly connected to a metal wire 405, one end of the metal wire 405 passes through the sliding frame 404, and the surface of the sliding frame 404 is slidably connected to a sliding tube 406, and the sliding tube 406 is fixedly connected to one end of the metal wire 405, and the internal thread of the sliding tube 406 is connected to a bolt 407, and the placement plate 403 is fixedly connected to an anti-slip pad 408, so that the material It is placed on the anti-skid pad 408, and the anti-skid pad 408 increases the friction force on the surface of the placement plate 403. The sliding frame 404 is provided with an inclined groove 409 relative to the position of the bolt 407. The vertical section of the inclined groove 409 is triangular. The inclined groove 409 with a triangular vertical section can better limit the position of the bolt 407, thereby limiting the position of the sliding tube 406. The surface of the sliding frame 404 is rotatably connected with a rotating wheel 410, and the rotating wheel 410 is slidably connected to the metal wire 405. During the sliding of the metal wire 405, the rotating wheel 410 can adjust the sliding direction of the metal wire 405 to reduce the wear between the metal wire 405 and the sliding frame 404.

[0034] like Figure 1 and Figure 4As shown, the auxiliary structure 5 includes a fixed frame 51, which is fixedly connected to the fixed ring 401, and a clamping rod 52 is slidably connected in the fixed frame 51. A clamping hole 53 is opened on the surface of the rotating frame 402, and the size of the clamping hole 53 is adapted to the size of the clamping rod 52. The arc surface of the clamping rod 52 is sleeved with a spring 54, and the two ends of the spring 54 are respectively fixedly connected to the fixed frame 51 and the clamping rod 52. When the spring 54 contracts, the clamping rod 52 will be inserted into the inner wall of the clamping hole 53 with the help of the pulling force of the spring 54. At this time, the spring 54 achieves the effect of automatically resetting the clamping rod 52, and the arc surface of the clamping rod 52 is rotatably connected to a rotating plate 55, and the arc surface of the fixed ring 401 is fixedly connected to a blocking rod 56. After the blocking rod 56 is located between the rotating plate 55 and the fixed frame 51, the blocking rod 56 reaches the position of limiting the rotating plate 55, thereby preventing the clamping rod 52 from affecting the rotation of the rotating frame 402 due to the pulling force of the spring 54.

[0035] The overall working principle is that when the aging test is performed on the material, the rotating plate 55 is first pulled, and the rotating plate 55 will drive the clamping rod 52 to slide along the fixed frame 51. The sliding of the clamping rod 52 will stretch the spring 54. When the rotating plate 55 moves to a suitable position, the rotating plate 55 is rotated. At this time, the blocking rod 56 is located between the rotating plate 55 and the fixed frame 51. The blocking rod 56 reaches the position of limiting the rotating plate 55, thereby preventing the clamping rod 52 from affecting the rotation of the rotating frame 402 due to the tension of the spring 54. Then, the rotating frame 402 is rotated. The rotation of the rotating frame 402 will drive the placement plate 403 to move. When the clamping hole 53 is aligned with the clamping hole 53, the clamping hole 53 is aligned with the clamping hole 53. After the rod 52 is aligned, the rotating plate 55 is rotated in the opposite direction. When the rotating plate 55 is out of contact with the blocking rod 56, the clamping rod 52 will be inserted into the inner wall of the clamping hole 53 with the help of the pulling force of the spring 54. At this time, the spring 54 can automatically reset the clamping rod 52. The clamping rod 52 can limit the position of the rotating frame 402, thereby limiting the position of the placement plate 403, preventing the placement plate 403 from shaking and affecting the experimenter's operation during the process of placing materials. Then, the material is placed on the anti-skid pad 408, and the anti-skid pad 408 increases the friction force on the surface of the placement plate 403. Then, along the placement The sliding frame 404 is moved on the surface of the plate 403, and the movement of the sliding frame 404 drives the metal wire 405 to move. When the metal wire 405 moves to a suitable position, the metal wire 405 is pressed on the material, and then the sliding tube 406 is slid along the surface of the sliding frame 404. The sliding of the sliding tube 406 will tighten the metal wire 405. At this time, the metal wire 405 will be pressed tightly on the surface of the material, thereby limiting the position of the material. Then, the bolt 407 is rotated, and the bolt 407 will move with the help of the thread to abut against the inner wall of the inclined groove 409. At this time, the inclined groove 409 with a triangular vertical section can better limit the bolt 407 is positioned to limit the position of the slide tube 406. During the sliding of the metal wire 405, the rotating wheel 410 can adjust the sliding direction of the metal wire 405 to reduce the wear between the metal wire 405 and the slide frame 404. Then, the ultraviolet lamp tube 3 is turned on with the help of the controller 2. The ultraviolet light emitted by the ultraviolet lamp tube 3 will accelerate the aging speed of the material after irradiating the surface of the material. Since the ultraviolet lamp tube 3 is located between the two placement plates 403, the materials on the surfaces of the two placement plates 403 will not block each other, thereby ensuring the accuracy of the test results and improving the practicality of the aging tester.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
