Description

Technical Field

[0001] This utility model relates to the field of material testing equipment technology, and in particular to a portable ultraviolet composite test chamber. Background Technology

[0002] The UV composite test chamber simulates ultraviolet radiation, temperature and humidity changes, condensation, and spraying conditions in the natural environment to conduct accelerated aging tests on materials. It uses fluorescent ultraviolet lamps as a light source to simulate the ultraviolet part of sunlight. Combined with temperature and humidity control systems, it can reproduce the aging effects that occur outdoors over months or years within a few days or weeks.

[0003] However, most existing UV composite test chambers are designed to be in a fixed position, which is inconvenient for transportation and movement. Although a few have wheels installed at the bottom to facilitate movement, it is not easy to directly locate the position of the UV composite test chamber after it is moved to a fixed position. This may result in the UV composite test chamber moving during use, affecting the test results. Moreover, the UV composite test chamber is prone to collisions due to blind spots during movement, which may damage the internal structure and prevent effective testing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a portable ultraviolet composite test chamber.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable ultraviolet composite test chamber, comprising: a test chamber body, two base frames fixedly installed at the bottom of the test chamber body, two movable wheels rotatably installed at the bottom of each of the two base frames, a limiting structure provided at the bottom of the test chamber body, the limiting structure including a connecting plate, the connecting plate fixedly installed between the two base frames, a threaded rod rotatably installed between the connecting plate and the test chamber body, a movable plate threadedly connected to the outer side of the threaded rod, four support frames fixedly installed at the bottom of the movable plate, protective pads fixedly installed at the bottom of each of the four support frames, and protective structures provided on all four sides of the movable plate.

[0006] In a preferred embodiment, two guide columns are fixedly installed between the connecting plate and the test chamber, and both guide columns penetrate the moving plate and slide in contact with the moving plate.

[0007] In a preferred embodiment, a motor is fixedly installed inside the test chamber, and the output end of the motor inside the test chamber passes through the bottom of the test chamber and is fixedly connected to a threaded rod.

[0008] In a preferred embodiment, the protective structure includes a U-shaped frame, and storage slots are provided on all four sides of the movable plate. The U-shaped frame is disposed inside the storage slots and slides in contact with the movable plate. A protective plate is rotatably mounted on the inner side of the U-shaped frame.

[0009] In a preferred embodiment, a first magnetic block is fixedly installed on both sides of the U-shaped frame, and sliding grooves are formed on both sides of the storage slot. The two first magnetic blocks are respectively disposed inside the two sliding grooves and slide in contact with the moving plate.

[0010] In a preferred embodiment, two magnetic blocks are fixedly installed on both the front and rear sides of the slide, and the first magnetic block and the two second magnetic blocks are designed to attract each other with opposite magnetic properties.

[0011] In a preferred embodiment, two return springs are fixedly installed on one side of the U-shaped frame, a movable block is fixedly installed on one end of the two return springs, a square insert is fixedly installed on one side of the movable block, and a lever is fixedly installed on both the upper and lower sides of the movable block.

[0012] In a preferred embodiment, the square insert extends through one side of the U-shaped frame and slides in contact with the U-shaped frame, and a slot is provided on one side of the protective plate, with the square insert and the slot being of matching size.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. This utility model uses a motor to drive a threaded rod to rotate, which in turn moves the movable plate on the outside of the threaded rod downward, causing the four support frames and their bottom protective pads to move downward as well. The four protective pads will come into contact with the ground, thus subjecting the test chamber to adhesive and frictional forces for limiting its position. This prevents the test chamber from moving after transportation and affecting the test, thereby improving the performance of the UV composite test chamber.

[0015] 2. Through the designed protective structure, the test chamber can effectively prevent direct impact from other objects during movement. The four protective plates will contact other objects first, thus preventing the test chamber from being directly damaged by collisions due to blind spots. This improves the protective effect of the UV composite test chamber. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1-4As shown, this utility model provides a technical solution: a portable ultraviolet composite test chamber, comprising: a test chamber body 11, two base frames 12 fixedly installed at the bottom of the test chamber body 11, two casters 13 rotatably installed at the bottom of each of the two base frames 12, a limiting structure 2 provided at the bottom of the test chamber body 11, the limiting structure 2 including a connecting plate 21, the connecting plate 21 being fixedly installed between the two base frames 12, a threaded rod 22 rotatably installed between the connecting plate 21 and the test chamber body 11, and the outer side of the threaded rod 22 being threadedly connected to... The movable plate 23 has four support frames 24 fixedly installed at its bottom, and protective pads 25 are fixedly installed at the bottom of each of the four support frames 24. Protective structures 3 are provided on all four sides of the movable plate 23. Two guide columns 26 are fixedly installed between the connecting plate 21 and the test chamber 11. Both guide columns 26 penetrate the movable plate 23 and slide in contact with it. A motor is fixedly installed inside the test chamber 11. The output end of the motor inside the test chamber 11 penetrates the bottom of the test chamber 11 and is fixedly connected to the threaded rod 22.

[0029] In this embodiment, the threaded rod 22 can drive the moving plate 23 to move up and down when it rotates, thereby adjusting the position of the four support frames 24. This ensures that the protective pads 25 at the bottom of the four support frames 24 are suspended during movement. After moving to the desired position, the four protective pads 25 will fall to the ground. The anti-slip design of the protective pads 25 effectively limits the movement of the test chamber 11, preventing it from moving during testing. The two guide pillars 26 effectively limit the movement of the moving plate 23, ensuring that the threaded rod 22 can stably drive the moving plate 23 to move when it rotates, and that the moving plate 23 does not rotate with the threaded rod 22, thus ensuring the stability of the structure.

[0030] Example 2

[0031] like Figure 1-6As shown, the protective structure 3 includes a U-shaped frame 31. The movable plate 23 has storage slots 32 on all four sides. The U-shaped frame 31 is located inside the storage slots 32 and slides in contact with the movable plate 23. A protective plate 33 is rotatably mounted inside the U-shaped frame 31. First-order magnetic blocks 34 are fixedly installed on both sides of the U-shaped frame 31. Slide grooves 35 are formed on both sides of the storage slots 32. Two first-order magnetic blocks 34 are respectively located inside the two slide grooves 35 and slide in contact with the movable plate 23. Second-order magnetic blocks 36 are fixedly installed on both the front and rear sides of the slide grooves 35. The first magnetic block 34 and the two second magnetic blocks 36 are designed to attract each other with opposite magnetic properties. Two return springs 37 are fixedly installed on one side of the U-shaped frame 31. A moving block 38 is fixedly installed on one end of the two return springs 37. A square insert 39 is fixedly installed on one side of the moving block 38. A lever 310 is fixedly installed on both the upper and lower sides of the moving block 38. The square insert 39 passes through one side of the U-shaped frame 31 and slides in contact with the U-shaped frame 31. A slot 311 is opened on one side of the protective plate 33. The square insert 39 and the slot 311 are matched in size.

[0032] In this embodiment, the storage slot 32 and the U-shaped frame 31 work together to effectively store the U-shaped frame 31 and the protective plate 33 between them after the UV composite test chamber is transported and fixed. This prevents the protective plate 33 from obstructing the operation of the UV composite test chamber and facilitates its use by staff. The first magnetic block 34 can limit the position of the U-shaped frame 31 through the magnetic attraction between the first magnetic block 34 and the second magnetic block 36. On the other hand, the cooperation between the first magnetic block 34 and the sliding groove 35 can ensure that the first magnetic block 34 can only slide inside the sliding groove 35, thereby limiting the movement of the U-shaped frame 31 and preventing it from moving too much and coming off the inside of the storage slot 32. The square insert 39 and the slot 311 work together to limit the protective plate 33 when the square insert 39 is inserted into the slot 311, thereby preventing the protective plate 33 from rotating after adjustment and affecting the use of the structure.

[0033] Working principle:

[0034] like Figure 1-6As shown, when the test chamber 11 needs to be moved, pull the four U-shaped frames 31 to move them from inside the storage slot 32 to the outside. Then, the first magnetic block 34 and the second magnetic block 36 on the outside are attracted to each other to fix the position of the U-shaped frames 31. Then, move the lever 310 to move the square insert 39 out of the slot 311 through the moving block 38, releasing the rotation limit on the protective plate 33. At this time, the protective plate 33 can be rotated ninety degrees and placed vertically. Then, through the elastic action of the return spring 37, the moving block 38 and the square insert 39 are moved out of the slot 311. The square insert 39 on one side passes through the U-shaped frame 31 and is inserted into the slot 311 to limit and fix the protective plate 33, thereby completing the four-sided protection effect of the test chamber 11. When the test chamber 11 moves, the design of the four protective plates 33 can effectively prevent the test chamber 11 from being directly hit by other objects when it collides with them. This effectively avoids the situation where the test chamber 11 is directly damaged by collisions due to the influence of blind spots, and improves the protection effect of the UV composite test chamber.

[0035] After the movement is completed, the motor inside the test chamber 11 is started. The specific model of the motor is not described, but is based on the compatible equipment. The motor will drive the threaded rod 22 to rotate, thereby driving the moving plate 23 on the outside of the threaded rod 22 to move downward. This causes the four support frames 24 and the protective pads 25 at the bottom to move downward as well. The four protective pads 25 will come into contact with the ground, thereby subjecting the test chamber 11 to adhesive and frictional forces to limit its movement. This prevents the test chamber 11 from moving after transportation and affecting the test, thus improving the performance of the UV composite test chamber.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
