Technical Field
[0001] This utility model relates to the field of ultraviolet light test chamber technology, and in particular to an ultraviolet light weather resistance test chamber with a protective device. Background Technology
[0002] In fields such as material performance testing and product quality inspection, ultraviolet (UV) weathering chambers are widely used to simulate UV irradiation in natural environments to evaluate the weather resistance of materials or products. However, existing UV weathering chambers still have many shortcomings in structural design and functional implementation. Regarding the installation and maintenance of UV lamps, traditional chambers have complex lamp installation structures, often requiring multiple tools for installation and disassembly, making the process cumbersome and time-consuming. When lamps malfunction or age, quick replacement is difficult, increasing both manpower and time costs for equipment maintenance. Furthermore, deterioration in lamp performance can lead to deviations in test results, compromising the accuracy of test data. In terms of environmental control, existing chambers lack effective measures to handle dust, debris, and other impurities generated during testing. Accumulation of these impurities inside the chamber not only contaminates test samples and interferes with test results but also adheres to the surface of the UV lamps, reducing their transmittance and lifespan. Meanwhile, the test chamber's poor sealing performance allows outside air and dust to easily enter, causing external environmental factors to interfere with the test conditions such as temperature, humidity, and light, making it difficult to maintain a stable test environment and meet the requirements of high-precision weather resistance testing. Furthermore, the air filter components of traditional test chambers are inconvenient to install and disassemble, and difficult to clean and maintain. With increasing usage time, the filtration effect gradually decreases, further weakening the test chamber's ability to control the test environment. Therefore, we propose a UV weather resistance test chamber with a protective device to solve this problem. Utility Model Content

[0010] In this utility model, an ultraviolet weathering test chamber with a protective device is provided. It is equipped with a mounting plate, a buckle assembly, and an ultraviolet lamp. By pulling the push plate horizontally left and right, the push plate drives the pull rod to move. The pull rod pulls the slide plate to slide within the slide frame, compressing the first spring, causing the insert plate to detach from the inside of the test chamber. At this time, by pulling the push plate horizontally up and down, the slide frame drives the connecting plate and the square plate to slide within the slide groove, compressing the second spring and the third spring, causing the insert to detach from the inside of the mounting plate. This facilitates the disassembly of the mounting plate and the lamp. This structure is simple and easy to operate, and facilitates the quick installation, disassembly, and double fixation of the mounting plate and the ultraviolet lamp. It allows the ultraviolet lamp to be replaced in time when it malfunctions or ages, avoiding the impact of lamp performance degradation on the accuracy of test results, reducing the cost of repeated tests due to inaccurate test data, and the double-fixed and stable installation of the ultraviolet lamp will not shift its position due to vibration or other factors during the test. It can continuously and stably emit ultraviolet light to the test sample, ensuring the consistency and stability of the test environment. This utility model describes a UV weathering test chamber with a protective device. It includes a dust extraction hood, a first connecting pipe, an air pump, a second connecting pipe, a filter plate, a filter box, and a disassembly assembly. After the air pump is started, air is drawn into the dust extraction hood through the first connecting pipe. The dust extraction hood collects dust, debris, and other impurities generated during the test. The air then enters the second connecting pipe after passing through the air pump and finally flows into the filter box. The filter plate inside the filter box filters the air, intercepting dust and impurities. The purified air is discharged through the exhaust pipe. Pulling the pull plate causes the connecting shaft and slider to slide upwards within the cylindrical groove, compressing the fourth spring and causing the insertion rod to be pulled out from inside the filter plate. At this point, the filter plate loses its fixing function from the insertion rod and can be removed from the filter box. This allows for efficient dust and debris removal and purification of impurities generated during the process, preventing their accumulation inside the test chamber, reducing dust accumulation on the lamp surface, and avoiding contamination or interference of impurities with the samples. This ensures the reliability of the test results. The sealing ring on the inner wall of the front side of the test chamber fits tightly with the door, effectively preventing external air and dust from entering the test chamber, avoiding interference from external environmental factors on the test conditions, and facilitating quick installation and removal of the filter plate, as well as easy cleaning of the filter plate.

[0015] In this embodiment, cylindrical grooves are provided inside both sides of the filter box 12. Disassembly components 6 are provided inside both sets of cylindrical grooves. Each disassembly component 6 includes a slider 603, with a connecting shaft 602 and a plug rod 604 fixedly installed at both ends of the slider 603. The plug rod 604 is movably inserted into the filter plate 11. A spring 605 is sleeved on the outer side of the connecting shaft 602, with both ends of the spring 605 fixedly connected to the slider 603 and the top inner wall of the cylindrical groove, respectively. A pull plate 601 is fixedly installed on the top of the connecting shaft 602. The filter plate 11 is installed inside the test chamber 1 to facilitate quick installation and removal. Four sets of sliding frames 501 are slidably installed inside the corresponding placement slots. Each of the four sets of sliding frames 501 is equipped with a spring 508. The two ends of the four sets of springs 508 are fixedly connected to the corresponding slide plate 503 and the inner wall of one side of the sliding frame 501. Four sets of pull rods 502 slide through to one side of the test chamber 1. Each of the four sets of pull rods 502 has a push plate fixedly installed on one side to facilitate quick reset of the insertion plate 504 and double fixation of the mounting plate 3.
[0016] In this embodiment, each of the four placement slots is equipped with a second spring 509. The two ends of each of the four springs 509 are fixedly connected to the corresponding sliding frame 501 and one inner wall of the placement slot, respectively, facilitating the quick reset of the insert block 507 and the quick installation of the mounting plate 3. The four square plates 506 are slidably installed inside the corresponding sliding grooves. Each of the four sliding grooves is equipped with a third spring 510. The two ends of each of the four third springs 510 are fixedly connected to the corresponding square plate 506 and one inner wall of the sliding groove, respectively, facilitating the quick reset of the sliding frame 501 and the quick installation of the mounting plate 3. For assembly and disassembly, a reflective prism plate 2 is fixedly installed on the inner wall of the top of the test chamber 1. The reflective prism plate 2 is located between two sets of ultraviolet lamps 4. A sealing ring 13 is provided on the inner wall of the front side of the test chamber 1. The inside of the sealing ring 13 is movably abutted against the chamber door 14. The chamber door 14 is rotatably connected to the test chamber 1. A cleaning door and an exhaust pipe are respectively rotatably and fixedly installed on the front and right sides of the filter box 12. A control button 15 is provided on the front top of the test chamber 1 to facilitate the reflection of the light emitted by the ultraviolet lamps 4, so that the light is more evenly distributed in the test chamber 1, which facilitates the discharge of purified air.
[0017] In this embodiment, during use, by pulling the push plate horizontally left and right, the push plate moves the pull rod 502, which in turn moves the slide plate 503 within the slide frame 501, compressing the first spring 508 and causing the insert plate 504 to disengage from the inside of the test chamber 1. Then, by pulling the push plate horizontally up and down, the slide frame 501 moves the connecting plate 505 and the square plate 506 within the slide groove, compressing the second spring 509 and the third spring 510, causing the insert block 507 to disengage from the inside of the mounting plate 3. This facilitates the disassembly of the mounting plate 3 and the lamp tube. During installation, this operation is repeated. Under the resetting action of springs 508, 509, and 510, the insert 507 is re-inserted into the mounting plate 3, and the insert 504 is re-inserted into the test chamber 1, thus installing and doubly securing the mounting plate 3 and the ultraviolet lamp tube 4. After the air pump 9 starts, it draws air from the dust suction hood 7 through the connecting pipe 8. The dust suction hood 7 collects dust, debris, and other impurities generated during the test within the test chamber 1. The air, after passing through the air pump 9, enters the connecting pipe 10 and finally flows into the filter box 12. The filter plate 11 inside the filter chamber 12 filters the air, intercepting dust and impurities. The purified air is discharged through the exhaust pipe, maintaining the cleanliness of the air inside the test chamber 1 and preventing impurities from affecting the irradiation effect of the test samples and the ultraviolet lamps 4, thus ensuring a stable test environment. The reflective prism 2 on the inner wall of the top of the test chamber 1 is located between the two sets of ultraviolet lamps 4, which can reflect the light emitted by the ultraviolet lamps 4, making the light distribution more uniform inside the test chamber 1, enhancing the irradiation effect on the test samples, and ensuring the accuracy and reliability of the test results. The sealing ring 13 on the inner wall of the front side of the test chamber 1 is tightly abutted against the door 14. When the door 14 is closed, a sealed space is formed to prevent outside air, dust, etc. from entering the test chamber 1, maintaining the stability of the environment inside the test chamber 1, and ensuring that the test conditions are not disturbed by the outside. When it is necessary to clean or replace the filter plate 11, pull the pull plate 601. The pull plate 601 drives the connecting shaft 602 and the slider 603 to slide upward in the cylindrical groove, compressing the spring 605, so that the insertion rod 604 is pulled out from inside the filter plate 11. At this point, the filter plate 11 loses its fixing effect from the insertion rod 604, and can be removed from the filter box 12 for convenient subsequent maintenance. After maintenance is completed, release the pull plate 601. Under the elastic force of the spring 605, the slider 603 drives the connecting shaft 602 and the insertion rod 604 to reset, and the insertion rod 604 is reinserted into the filter plate 11, thus fixing the filter plate 11 in place and ensuring that the filter box 12 continues to perform its air filtration function.
