[0002] The UV aging test chamber is a light aging test equipment used for non-metallic materials. It is mainly used to test the aging of non-metallic materials under sunlight and artificial light. The current test chamber installs a UV lamp as a light source in the cavity. The test object is irradiated with this light source, and the aging data is obtained based on the changes of the test object under light.

[0003] At present, the light sources in the test chamber are basically fixed on the inner wall of the test chamber, mainly installed on both sides of the test chamber to provide sufficient ultraviolet light for the test object. However, this also results in the fixation of the labor light source. The angle and range of the fixed light source are limited, and the test object cannot be fully illuminated. In addition, the natural light source, including artificial light sources, is not static. In order to better detect, an adjustable ultraviolet aging test chamber is established.

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-5 The utility model is an adjustable ultraviolet aging test box. Figure 1 As shown, the adjustable UV aging test box of this embodiment includes a box body 1, an inner cavity 3 is set inside the box body 1, and mounting plates 4 are set on the opposite side walls of the inner cavity 3, and UV lamps are evenly inlaid and connected on the opposite side walls of the two mounting plates 4, and side grooves 8 are opened on the opposite side walls of the inner cavity 3, and screws 9 are rotatably connected in the side grooves 8. Two follower blocks 10 are threadedly connected on the screws 9, and the mounting plate 4 is rotatably connected to the following block 10 below through the bottom edge, and the side wall of the inner cavity 3 near the top is rotatably connected with a telescopic rod 11, and the telescopic rod 11 is detachably connected to the following block 10 located above through one end;

[0016] A No. 1 motor 6 is inlaid and connected in the middle of the top side wall of the box body 1. A heat dissipation net 2 is fixedly connected to the top side wall of the box body 1. The heat dissipation net 2 is communicated with the installation area of ​​the No. 1 motor 6. A connecting groove 7 is opened on the top of the box body 1 and on both sides of the No. 1 motor 6. A linkage shaft 5 is rotatably connected in the connecting groove 7. The output end of the No. 1 motor 6 extends into the connecting groove 7 and is fixedly connected to one end of the linkage shaft 5. One end of the side groove 8 extends into the connecting groove 7 and is fixedly connected to a driven gear 13. A driving gear 12 is meshed and connected to one side of the driven gear 13. The driving gear 12 is fixedly connected to one end of the linkage shaft 5 away from the No. 1 motor 6 through the middle of one side wall thereof.

[0017] The technical effect of this scheme is that the test object is placed in the inner cavity 3, the hatch is closed, and the ultraviolet lamp on the mounting plate 4 is started to irradiate the test object. As time goes by, the No. 1 motor 6 is started to drive the two linkage shafts 5 to rotate, and the two screws 9 are driven to rotate through the rotation of the driving gear 12 and the driven gear 13. Through the characteristics of the threaded connection, the mounting plate 4 can be driven to rise and fall synchronously through the follower block 10, and then the telescopic rod 11 is started to expand the upper part of the mounting plate 4 outward, so that it rotates and tilts along the connection with the follower block 10 below, so as to realize lifting and lowering and angle adjustment, simulate the changes in light in real situations, and make the output data more in line with the real situation.

[0018] A side plate 14 is set up on both sides of the mounting plate 4, and the opposite side walls of the two mounting plates 4 are evenly connected to the follower shaft 18 for rotation. A storage groove 19 is opened on the side wall of the mounting plate 4 close to the ultraviolet lamp, and the side wall of the ultraviolet lamp away from the storage groove 19 is fixedly connected to the arc-shaped docking plate 22, and a mask curtain 20 is inserted in the storage groove 19. The storage groove 19 and the mask curtain 20 are corresponding arc-shaped structures, and the mask curtain 20 is fixedly connected to the bottom side wall of the follower shaft 18 through one end. A No. 2 motor 21 is inlaid and connected in the middle of the bottom side wall of the mounting plate 4, and the output end of the No. 2 motor 21 is fixedly connected to the rotating rod 17, one end of the rotating rod 17 passes through the side walls of the mounting plate 4 on both sides and is fixedly connected to the connecting column 16, and the end of the connecting column 16 away from the rotating rod 17 is fixedly connected to the rotating shaft 15, and the rotating shaft 15 is rotatably connected to the middle of the side wall of the side plate 14 away from the follower shaft 18 through one end.

[0019] The technical effect of this solution is that, because in reality, light may not be able to directly shine on the detection object, but there will be a certain degree of obstruction. In order to simulate this situation, a storage slot 19 is opened on the mounting plate 4 and a mask curtain 20 is set in the storage slot 19. The mask curtain 20 is connected to the two side plates 14 through the follower shaft 18, and then the No. 2 motor 21 installed in the mounting plate 4 is started to drive the rotating rod 17 to rotate, and the rotating shaft 15 is driven to make a circular motion through the connecting column 16, so as to bring the mask curtain 20 out of the storage slot 19, and finally fit with one end of the docking plate 22 to shield the ultraviolet lamp, simulating the situation where the real light source is blocked, thereby improving the variability of the detection scene.

[0020] Specifically, when the utility model is used, starting the No. 1 motor 6 can simultaneously drive the two screw rods 9 to rotate, and drive the lifting and lowering of the mounting plate 4 through the threaded connection. At the same time, the telescopic activity of the telescopic rod 11 can adjust the mounting plate 4 to different heights and inclination angles as needed, thereby increasing the adjustment range and the flexibility of the adjustment, and simulating the variable light source in reality. Of course, the accuracy of the mounting plate 4 can also be maintained as needed, so that the detected data is more in line with the actual situation, thereby increasing the practicality of the equipment. The drive of the No. 2 motor 21 can control the mask curtain 20 to block the corresponding ultraviolet lamp tube. The mask curtain 20 is made of a translucent gauze structure, which blocks the light while ensuring the irradiation of the detected object, thereby simulating the situation that the light source is shielded in the real environment, and increasing the variability of the detection by coordinating with the adjustment of the mounting plate 4, and increasing the adjustability of the detection equipment. In addition, the No. 1 motor 6 and the No. 2 motor 21 both use double-headed motors, which can drive the activities of two components at the same time to reduce energy consumption.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
