DETAILED DESCRIPTION

[0030] The present application will be further described below in conjunction with the accompanying Figures 1-9 drawings.

[0031] Referring to Figures 1-9 The embodiment of the application discloses a kind of ultraviolet lamp irradiation intensity test device, including bottom plate 1, top plate 2 and ultraviolet lamp 4, top plate 2 is provided at the place of bottom plate 1 directly above, top plate 2 is fixedly connected with bottom plate 1 by two support plates 3, ultraviolet lamp 4 is installed on the position close to top end of the two support plates 3 by mounting structure, the position close to top end of the side of the two support plates 3 is fastened with fixed plate 18 by screw, the two fixed plates 18 are provided with lifting plate 6 by intermittent lifting structure, and the lifting plate 6 is provided with placing structure for placing multiple instruction cards;

[0032] The intermittent lifting structure includes a vertical plate 17 fixedly connected to the bottom of the fixed plate 18. A sleeve frame 19 is movably fitted on the vertical plate 17. The lifting plate 6 is connected to the bottom of the two sleeve frames 19. Limiting structures are provided on the vertical plate 17 and the sleeve frames 19. A U-shaped plate 8 is fastened to the front of the support plate 3 near the middle by screws. A first electric telescopic rod 9 is installed in the middle of the front of the U-shaped plate 8. A switching frame 10 is provided at one end of the output shaft of the first electric telescopic rod 9 passing through the U-shaped plate 8. An automatic switching structure is provided on the switching frame 10. The switching frame 10 is U-shaped. A first insert rod 11 is fixedly passed through one end of the switching frame 10. The other end of the switching frame 10... A second insert rod 26 is fixedly inserted through the frame. A fixed frame 12 is installed on one side of the sleeve frame 19. A first horizontal groove 14 is opened on the horizontal section of the fixed frame 12, and a vertical groove 13 is opened on the vertical section of the fixed frame 12. Adjacent first horizontal grooves 14 and vertical grooves 13 are interconnected. An embedded plate 15 is fixedly embedded at the top and bottom of the fixed frame 12. A first inclined groove 16 is opened on the embedded plate 15, which is connected to the lowest first horizontal groove 14 and vertical groove 13. Multiple sets of second horizontal grooves 28 and second inclined grooves 27 are opened on the other side of the sleeve frame 19. The second horizontal grooves 28 and second inclined grooves 27 are spaced apart from each other. 27 are distributed vertically on the sleeve frame 19. A sealing structure is provided at the left end of the second horizontal groove 28 and the lower end of the second inclined groove 27. One end of the first insertion rod 11 is movably inserted into the first horizontal groove 14. When detecting the intensity of the ultraviolet lamp 4 at different height positions, firstly, the first electric telescopic rod 9 is activated, causing one end of the first insertion rod 11 on the switching frame 10 to slide in the lowest first horizontal groove 14 on the fixed frame 12. When one end of the first insertion rod 11 slides in the first inclined groove 16, it pulls the sleeve frame 19 up and down on the vertical plate 17. And when one end of the first insertion rod 11 slides to the vertical groove 13 at one end of the first inclined groove 16... Under the weight of the frame 19 and the lifting plate 6, the frame 19 and the lifting plate 6 move up and down on the vertical plate 17. At this time, one end of the first insertion rod 11 slides into the adjacent first horizontal groove 14. When it is necessary to continue to move the lifting plate 6 to adjust the height, the first electric telescopic rod 9 drives one end of the first insertion rod 11 to slide in the opposite direction in the corresponding first horizontal groove 14. When one end of the first insertion rod 11 slides to the adjacent vertical groove 13, under the weight of the frame 19 and the lifting plate 6, the frame 19 continues to move down on the vertical plate 17, thereby automatically driving the lifting plate 6 to move down intermittently to detect the intensity of the ultraviolet lamp 4 at different height positions.

[0033] See Figures 1-6The installation structure includes a fixed tube 20 that passes through the support plate 3 near the top. A pull rod 21 moves through the fixed tube 20. A pull plate 22 is installed on one end of the pull rod 21, and a first handle 23 is installed on the pull plate 22. A clamping cylinder 24 is installed on the other end of the pull rod 21. A spring 25 is sleeved on the pull rod 21. The two ends of the spring 25 are respectively connected to the clamping cylinder 24 and the fixed tube 20. The first handle 23 is used to pull open the two clamping cylinders 24 on the two support plates 3, and the spring 25 is compressed. When the ultraviolet lamp 4 is placed between the two clamping cylinders 24, the first handle 23 is released. Under the elastic force of the spring 25, the two clamping cylinders 24 are clamped to both ends of the ultraviolet lamp 4, thereby installing the ultraviolet lamp 4. This makes the installation or removal of the ultraviolet lamp 4 simpler and more convenient.

[0034] The automatic switching structure includes a second electric telescopic rod 30 installed on one side of the U-shaped plate 8. One end of the output shaft of the second electric telescopic rod 30 is fixedly connected to the switching frame 10. A sliding groove 31 is provided on the side of the switching frame 10 near the first electric telescopic rod 9. A T-shaped block 29 is connected to one end of the output shaft of the first electric telescopic rod 9. The T-shaped block 29 is slidably disposed in the sliding groove 31. When the second electric telescopic rod 30 is activated to move the switching frame 10, one end of the first insertion rod 11 can be pulled out from the fixed frame 12. At the same time, one end of the second insertion rod 26 is inserted into the uppermost second inclined groove 27 on the sleeve frame 19. In this way, when the first electric telescopic rod 9 is activated to move the switching frame 10 and the second insertion rod 26 back and forth as a whole, the sleeve frame 19 can be automatically moved intermittently upward on the vertical plate 17 to detect the light intensity of the ultraviolet lamp 4 at different height positions. This eliminates the need for the tester to manually reset the sleeve frame 19 on the vertical plate 17, further improving the efficiency of the test work.

[0035] The blocking structure comprises a first rotating shaft rotatably connected at the left end in the second transverse groove 28, a first stopper 32 fixedly sleeved on the first rotating shaft, a torsion spring connected between the first stopper 32 and the groove wall of the second transverse groove 28, a second rotating shaft rotatably connected at the lower end groove wall in the second inclined groove 27, a second stopper 33 fixedly sleeved on the second rotating shaft, and a torsion spring connected between the second stopper 33 and the groove wall of the second inclined groove 27. When one end of the second insertion rod 26 slides to the second stopper 33 at one end of the second inclined groove 27, the second stopper 33 is pushed away in the second inclined groove 27 with the continuous movement of the second insertion rod 26, and the second stopper 33 is reset by the elastic force of the torsion spring when the one end of the second insertion rod 26 moves away from the second stopper 33. Thus, the second insertion rod 26 can be reversely moved in the second transverse groove 28, and the second insertion rod 26 can be smoothly moved in the next second inclined groove 27 to automatically move the sleeve frame 19 on the first vertical plate 17. When the second insertion rod 26 moves to push away the first stopper 32 in the second transverse groove 28, the first stopper 32 is reset by the elastic force of the torsion spring, and the second insertion rod 26 is shielded by the first stopper 32 to be smoothly moved in the corresponding second inclined groove 27.

[0036] The limiting structure comprises a limiting plate fixedly connected at the bottom end of the vertical plate 17, a square plate with an outer diameter of 1.2 times the outer diameter of the vertical plate 17, and the limiting plate is movably attached to the inner wall of the sleeve frame 19. A magnetic block 35 is installed on the upper surface of the sleeve frame 19, and an iron block 34 is arranged on the vertical plate 17 and is fixedly attracted to the magnetic block 35. When the sleeve frame 19 is moved to the uppermost position on the vertical plate 17, the magnetic block 35 is attracted to the iron block 34, thereby limiting the sleeve frame 19 on the vertical plate 17. When the sleeve frame 19 is moved to the lowermost position on the vertical plate 17, the limiting plate limits the sleeve frame 19 on the vertical plate 17. Thus, during the switching process, the first insertion rod 11 can be smoothly inserted into the fixed frame 12, or the second insertion rod 26 can be smoothly inserted into the second inclined groove 27, so that the switching work can be smoothly performed. When the one end of the first insertion rod 11 slides in the first inclined groove 16, the one end of the first insertion rod 11 can pull away the magnetic block 35 from the iron block 34 by extruding the groove wall of the first inclined groove 16, so that the sleeve frame 19 on the vertical plate 17 can be intermittently moved.

[0037] Referring to Figure 1 , Figure 7 , Figure 8 and Figure 9The placing structure comprises an inner groove 37 formed in the lifting plate 6, the inner groove 37 is provided with a placing plate 38, the upper surface of the placing plate 38 is provided with a placing groove 39, a plurality of indication cards are arranged in the placing groove 39, the lifting plate 6 is hingedly provided with a flip plate 7 at the position of the inner groove 37, the flip plate 7 is provided with a test hole 43 at the middle position, the second handle 36 is arranged on the upper surface of the flip plate 7 and close to the two corners of the front side, the placing plate 38 and the bottom plate are provided with a transmission structure, the ultraviolet lamp 4 is turned on, the light intensity of the ultraviolet lamp 4 can be detected through the test hole 43.

[0038] The transmission structure comprises a U-shaped rod 40 fixedly connected to the left end of the placing plate 38, the U-shaped rod 40 is movably arranged through the lifting plate 6, the middle position of the left end surface of the bottom plate 1 is fixedly provided with a transmission plate 41, the transmission plate 41 is provided with a transmission groove 42, the transmission groove 42 is in a stepped shape, the U-shaped rod 40 is movably arranged through the transmission groove 42, the U-shaped rod 40 is arranged through the rectangular groove 5 formed in the supporting plate 3, when the lifting plate 6 is moved up or down and the intensity of the ultraviolet lamp is detected at different height positions, the transmission groove 42 can drive the U-shaped rod 40 to move, so that the placing plate 38 is moved during the intermittent movement of the lifting plate 6 in the vertical direction, thereby the indication cards are automatically switched to the position below the test hole 43 for testing work at different heights.

[0039] The implementation principle of the ultraviolet lamp irradiation intensity testing device is as follows: first, the flip cover plate 7 is opened by using the second handle 36 on the lifting plate 6, a plurality of indication cards are placed into the placing slots 39 on the placing plate 38, and then the flip cover plate 7 is re-closed. Then, the ultraviolet lamp 4 is started, and the ultraviolet intensity is detected on the indication cards through the test holes 43. When the intensity detection work needs to be performed at different positions, first, the first electric telescopic rod 9 is started, and the one end of the first plug rod 11 on the switching frame 10 slides in the lowermost first horizontal slot 14 on the fixed frame 12. When the one end of the first plug rod 11 slides in the first inclined slot 16, the sleeve frame 19 is moved up and down on the vertical plate 17, so that the magnetic block 35 is separated from the iron block 34. When the one end of the first plug rod 11 slides to the vertical slot 13 at one end of the first inclined slot 16, the sleeve frame 19 and the lifting plate 6 are moved up and down on the vertical plate 17 as a whole under the action of the gravity of the sleeve frame 19 and the lifting plate 6. At this time, the one end of the first plug rod 11 slides into the adjacent first horizontal slot 14. When it is needed to continue to move the lifting plate 6 to adjust the height, the first electric telescopic rod 9 drives the one end of the first plug rod 11 to slide reversely in the corresponding first horizontal slot 14. When the one end of the first plug rod 11 slides to the adjacent vertical slot 13, the sleeve frame 19 continues to move down on the vertical plate 17 under the action of the gravity of the sleeve frame 19 and the lifting plate 6, so as to automatically drive the intermittent downward movement of the lifting plate 6, and the intensity of the ultraviolet lamp 4 is detected at different height positions. In the process of the downward movement of the lifting plate 6, the U-shaped rod 40 is moved down in the transmission slot 42, so as to drive the movement of the placing plate 38. Thus, the indication cards are automatically switched to move to the position below the test holes 43 for testing work at different heights. After testing, the indication cards can be taken out for comparison, so that the illumination intensity tested on the indication cards at different height positions is compared, and the intensity detection work of the ultraviolet light at different heights is realized. When the next group of data is detected, a plurality of indication cards can be placed in the placing slots 39, the second electric telescopic rod 30 is started to drive the movement of the switching frame 10, the one end of the first plug rod 11 is pulled out of the fixed frame 12, and at the same time, the one end of the second plug rod 26 is inserted into the uppermost second inclined slot 27 of the sleeve frame 19. Thus, when the first electric telescopic rod 9 drives the switching frame 10 and the second plug rod 26 to move back and forth, the sleeve frame 19 is automatically moved up and down intermittently on the vertical plate 17, and the illumination intensity of the ultraviolet lamp 4 is detected at different height positions. Thus, the test personnel need not manually reset the sleeve frame 19 on the vertical plate 17, and the test work efficiency is further improved, and the operation is more labor-saving and convenient.

[0040] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application.
