[0004] The above-mentioned equipment can reduce the distortion of plastic products and affect the effect of ultraviolet test by abutting the two opposite end faces of the plastic product through the pressure plate and the bottom of the supporting cavity. When testing the test object, it is necessary to determine the specific intensity of the anti-ultraviolet lamp of the test object based on the distance between the ultraviolet light and the test object, and this requires multiple groups of comparisons to reduce the deviation of the test results. The test structure of the equipment and the irradiation structure of the ultraviolet lamp are both fixed, so it is inevitable to adjust the distance between the two for testing, and this requires staff to improve their equipment.

DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] Reference Figure 1 , Figure 3 and Figure 4As shown, a UV weathering test box comprises: a working box 1, electric telescopic rods 2 are fixedly connected to the four sides of the top of the working box 1, the bottom end of the electric telescopic rod 2 is fixedly connected to a mounting frame 3, an inner wall of the mounting frame 3 is provided with an ultraviolet lamp assembly 4, hoses 5 are fixedly connected to both sides of the top of the mounting frame 3, a connecting rod 6 is fixedly connected to the surface of the top of the electric telescopic rod 2, and the top of the hose 5 is fixedly connected to the bottom of the connecting rod 6;

[0029] When it is necessary to adjust the distance between the irradiation structure and the test object, the electric telescopic rod 2 drives the installation frame 3 at the bottom to descend. After the installation frame 3 descends, the internal ultraviolet lamp assembly 4 is driven to descend. After the ultraviolet lamp assembly 4 descends, the distance between the ultraviolet lamp assembly 4 and the test object is shortened. After the ultraviolet lamp assembly 4 approaches the test object, the irradiation intensity of the ultraviolet lamp assembly 4 on the test object is increased, so that different test results are obtained. The cables of the ultraviolet lamp assembly 4 are arranged in the hose 5 and the connecting rod 6, and the two sets of electric telescopic rods 2 can be adjusted separately, so that the equipment can test the same test object with different ultraviolet irradiation intensities at the same time, and the baffle 15 and the adjustment plate 19 are located at the bottom of the two sets of ultraviolet lamp assemblies 4, which can block the light of the two sets of ultraviolet lamp assemblies 4 to avoid mutual influence of light.

[0030] Reference Figures 1 to 3 As shown, the inner wall of the working box 1 is provided with a heat insulation layer 7, and support columns 8 are fixedly connected to both sides of the bottom of the working box 1;

[0031] The heat insulation layer 7 is arranged in the partition inside the working box 1, so as to keep the temperature inside the working box 1 warm, slow down the heat loss, and prevent the external temperature from affecting the temperature inside the working box 1. The support column 8 can support the bottom of the working box 1.

[0032] Reference Figure 1 , Figure 5 and Figure 6 As shown, both sides of the front of the working box 1 are rotatably connected to the box door 9, one side of the front of the box door 9 is rotatably connected to the handle 10, one side of the handle 10 is rotatably connected to the gear rod 11, and both ends of the gear rod 11 are rotatably connected to the inner wall of the box door 9, and the bottom of the gear rod 11 is meshed with a rack 12;

[0033] When it is necessary to open the box door 9, first turn the handle 10. The rotation of the handle 10 drives the gear rod 11 on one side to rotate. The rotation and engagement of the gear rod 11 drives the rack 12 at the bottom to slide in the box door 9, thereby putting the rack 12 into the box door 9, and then turn the box door 9 to open it. After closing the box door 9, turn the handle 10 to drive the gear rod 11 to engage and drive the rack 12 to move, so that the rack 12 is stuck in the other set of box doors 9, thereby fixing the two sets of box doors 9.

[0034] Reference Figure 2 and Figure 7 As shown, the inner bottom wall of the working box 1 is fixedly connected with a connecting frame 13, the inner wall of the connecting frame 13 is fixedly connected with a supporting rod 14, the surface of the supporting rod 14 is slidably connected with a baffle 15, one side of the supporting rod 14 is provided with a movable groove 16, and the bottom of the baffle 15 is slidably connected to the inner bottom wall of the working box 1, a threaded groove 17 is provided at the bottom of one side of the baffle 15, the inner wall of the threaded groove 17 is threadedly connected with a hand wheel 18, and the surface of the hand wheel 18 is slidably connected to the inner wall of the movable groove 16, the inner wall of the baffle 15 is slidably connected with an adjusting plate 19, one side of the adjusting plate 19 is provided with a card slot 20, one side of the inner wall of the baffle 15 is penetrated and plugged with a latch 21, and the surface of the latch 21 is plugged with the inner wall of the card slot 20;

[0035] Before the test, the test object is placed on the surface of the support rod 14. When multiple groups of different test objects need to be tested, the test objects are placed on the surface of the support rod 14, and the two groups of test objects are separated by the baffle 15. When the space size on both sides of the baffle 15 needs to be adjusted, the hand wheel 18 is first removed from the threaded groove 17, and then the baffle 15 is slid to make the baffle 15 slide on the surface of the support rod 14. After the baffle 15 is adjusted to a suitable position, one side of the hand wheel 18 is passed through the movable groove 16 and fixed to the threaded groove 17, so as to fix the position of the baffle 15. During the test, the adjustment plate 19 can be pulled out of the baffle 15, and then the latch 21 is inserted into the card slot 20 to fix the adjustment plate 19, so as to match the height of the two groups of ultraviolet lamp assemblies 4, and isolate the two groups of ultraviolet lamp assemblies 4 to avoid the two groups of ultraviolet lamp assemblies 4 with different heights from affecting each other, and the interior of the working box 1 is divided into two groups.

[0036] Working principle: first turn the box door 9 to open it, then place the test object on the surface of the support rod 14, and then close the box door 9. By turning the handle 10, the gear rod 11 is engaged to drive the rack 12 to move, so that the rack 12 is stuck in another set of box doors 9, thereby fixing the two sets of box doors 9. The ultraviolet lamp assembly 4 performs irradiation test on the test object. When it is necessary to adjust the distance between the irradiation structure and the test object, the electric telescopic rod 2 drives the bottom ultraviolet lamp assembly 4 to descend. After the ultraviolet lamp assembly 4 descends, the distance between it and the test object is shortened, so that different test results are obtained.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the utility model creation.
