DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a UV aging test device, comprising a test box 1, and a control box 2 installed on one side of the test box 1, a controller is installed inside the control box 2, the test box 1 is a rectangular box with an opening 3 on one side, a sealing door 4 is hinged on the side of the opening 3 away from the control box 2, and the other side of the sealing door 4 is connected to the test box 1 through a lock.

[0024] A temperature sensor 20 connected to the controller is installed on the inner wall of the test box 1. A multi-layer irradiation mechanism is arranged in intervals from top to bottom. The test box 1 and the control box 2 together constitute the ultraviolet aging test device; in actual use, the temperature in the test box 1 is monitored by the temperature sensor 20 to prevent the temperature in the test box 1 from being too high due to long-term irradiation, thereby causing damage to the irradiation mechanism.

[0025] like Figure 2 As shown, each layer of the irradiation mechanism includes two symmetrically arranged strip plates 5, and at least two ultraviolet lamp tubes 6 are arranged in parallel on the relatively close sides of the two strip plates 5. Lamp holders 7 are installed at both ends of the ultraviolet lamp tubes 6, and a fixing plate 8 is installed at the other end of the lamp holder 7. The fixing plate 8 is vertically fixed on the end of the strip plate 5, and the lamp holder 7 is connected to the controller. The lamp holder 7 provides support and power transmission for the ultraviolet lamp tubes 6; each lamp holder 7 is independently connected to the controller, so that when in use, the operator can independently operate the ultraviolet lamp tubes 6 according to the use requirements of each layer of the irradiation mechanism.

[0026] Among them, an arc plate 13 is installed on one side of each strip plate 5 close to the ultraviolet lamp tube 6, the concave surface of the arc plate 13 is arranged toward the ultraviolet lamp tube 6, and the concave axis of the arc plate 13 is arranged in the same direction as the length direction of the ultraviolet lamp tube 6, and a reflector is installed on the concave surface of the arc plate 13; the top of the test box 1 and the bottom of the carrier plate 14 are respectively provided with a reflective layer. The irradiation light of the ultraviolet lamp tube 6 can be concentrated on the object to be tested, thereby improving the use efficiency of the ultraviolet lamp tube 6.

[0027] like Figure 2 and Figure 3 As shown, a movable seat 9 is connected to one end of the strip plate 5 close to the opening 3, and the movable seats 9 on the same side are mounted on the slide rail 10 through a slider, and the slide rail 10 is fixedly connected to the inner wall of the test box 1, and a fastener is installed on the movable seat 9 to fasten it to the slide rail 10. In actual use, the fastener is a locking bolt, and the locking bolt is threadedly mounted on the side of the movable seat 9. The screw head of the locking bolt is located on the side of the movable seat 9 close to the opening 3, and the screw end of the locking bolt corresponds to the side of the slide rail 10. The operator turns the locking bolt, and the screw end of the locking bolt will be against the slide rail 10, thereby realizing the fastening of the movable seat 9 on the slide rail 10. After the movable seat 9 is locked, the position of the strip plate 5 in the test box 1 is fixed, and the test of the object to be tested can be carried out. If it is necessary to adjust the irradiation position of the ultraviolet lamp tube 6, the locking bolt can be directly unscrewed, and the strip plate 5 can be held and moved up and down to adjust the irradiation position of the ultraviolet lamp tube 6.

[0028] Among them, Figure 3 As shown, the two strip plates 5 are respectively provided with a sliding sleeve 12 on one side relatively far from the opening 3, and the sliding sleeve 12 is slidably mounted on a guide rod 11, and the two ends of the guide rod 11 are respectively connected to the upper and lower end surfaces of the test box 1. It provides a guiding function for the lifting and lowering adjustment of the strip plates 5, and also provides a supporting function for the strip plates 5.

[0029] A carrying mechanism for placing the test object is provided below each set of irradiation mechanisms, and the end of the carrying mechanism is detachably mounted on the inner wall of the test box 1. The number of the carrying mechanisms to be installed can be selected according to the volume of the test object, and the spacing between two adjacent carrying mechanisms can be adjusted, thereby further improving the adaptability of the entire test device.

[0030] The bearing mechanism includes a plurality of support blocks 19 installed on both sides of the interior of the test box 1, and the support blocks 19 are distributed below the irradiation mechanism; a bearing plate 14 is also provided below the irradiation mechanism of each layer, and the middle position of the bearing plate 14 is a concave structure, and the bottom of the concave structure is horizontal. When the temperature in the test box 1 is too high, the paint and coating on the surface of the object to be tested are likely to liquefy. At this time, the concave structure of the bearing plate 14 will receive the liquefied paint to prevent the paint from flowing along the surface of the bearing plate 14 to the irradiation mechanism below and adhering to the irradiation mechanism, affecting the irradiation. Use of the radiation mechanism; an annular frame 15 is provided in the concave structure, and a metal mesh 17 is installed on the inner side of the annular frame 15 to elevate and carry the object to be tested, ensuring that the object to be tested is in full and uniform contact with the air in the test box 1, so that heat can be transferred to the object to be tested, and the test results are accurate. The annular frame 15 is installed with a plurality of support legs 16, and the support legs 16 are placed on the carrier plate 14 to facilitate the removal of the metal mesh 17 from the carrier plate 14. A support skirt 18 is installed along the edge of the carrier plate 14, and the two ends of the support skirt 18 are correspondingly placed on the support block 19. In actual use, a gap is left between the support skirt 18 and the inner wall of the test box 1. With the support skirt 18 placed on the support block 19, the operator can directly lift the carrier plate 14 to remove the carrier plate 14 from the test box 1, so as to clean the carrier plate 14 or maintain the ultraviolet lamp tube 6 in the test box 1.

[0031] Furthermore, in order to prevent the support block 19 from obstructing the lifting and lowering operation of the ultraviolet lamp tube 6, each support block 19 is located in the middle of the strip plate 5, the length of the support block 19 is smaller than the strip plate 5, and the width of the support block 19 is smaller than the shortest distance from the side of the strip plate 5 to the inner wall of the test chamber 1.

[0032] Further, such as Figure 1 As shown, a display screen 21, a control panel 22 and an indicator light 23 are respectively installed on one end of the control box 2 close to the opening 3, and the display screen 21, the control panel 22 and the indicator light 23 are respectively connected to the controller.

[0033] Specifically, when the ultraviolet aging test device is in use, the operator first places the carrier plate 14 according to the size of the object to be tested, then places the object to be tested on the metal mesh 17, and adjusts the height of the ultraviolet lamp tubes 6 on both sides to align the ultraviolet lamp tubes 6 with the required irradiation position of the object, and finally closes the sealing door 4 to start the test; among them, if the object to be tested is large in size and a single irradiation mechanism cannot fully act on the object to be tested, only one carrier plate 14 can be retained and placed at the bottom of the test box 1, and then the multiple groups of irradiation mechanisms on both sides can be adjusted to ensure that the test device fully acts on the object to be tested.
