Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, and in particular to an adjustable ultraviolet aging test chamber. Background Technology

[0002] Ultraviolet (UV) aging is a type of solar irradiation aging, typically used to assess the rate at which a product ages under ultraviolet light. Solar irradiation aging is the primary cause of aging damage to outdoor materials. Indoor materials are also subject to a certain degree of solar irradiation aging or aging caused by ultraviolet light from artificial light sources.

[0003] According to the ultraviolet aging test chamber disclosed in Chinese patent application number CN202121522139.4, the chamber includes a chamber body, a control panel is provided on the upper side of one side of the chamber body, a sealed door is installed below the control panel, and side mounting chambers are respectively provided on both sides of the interior of the chamber body. In this utility model, by setting the light irradiation mechanism to be rotatable, the UV lamp can be avoided from being constantly exposed during other experiments, thus extending the service life of the UV lamp. Furthermore, the rotatable setting can simulate the light irradiation angle at different times and in different regions, making the test results more accurate.

[0004] However, in existing technologies, the UV lamps are kept on for extended periods during testing, causing the UV lamp holders to heat up. Prolonged heating can lead to increased internal temperature within the test chamber, which can affect temperature control during testing. Traditional test chambers do not have a heat dissipation structure and cannot effectively cool the UV lamps, which can negatively impact test results. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0025] like Figure 1-5 As shown, this utility model provides an adjustable ultraviolet aging test chamber, including a test chamber body 1 and a door 2. Ultraviolet lamps 3 are symmetrically arranged inside the test chamber body 1. Air guide components 4 are arranged inside the test chamber body 1 on the outer side of the two ultraviolet lamps 3. Support components 5 are arranged inside the test chamber body 1 with the diameter of the two ultraviolet lamps 3.

[0026] The air guide assembly 4 includes an air guide plate 41. The outer side of the ultraviolet lamp 3 is fixed to the inner wall of the air guide plate 41. The outer surface of the air guide plate 41 is fixed to the inner wall of the test chamber 1. A fan box 43 is provided on the outer side of one side of the test chamber 1, and fans are symmetrically arranged inside the fan box 43. A ventilation window 44 is symmetrically opened on the side of the fan box 43 away from the test chamber 1. A protective filter plate 46 is detachably fixed on the other side of the test chamber 1. Air inlets and outlets that cooperate with the fan box 43 and the protective filter plate 46 are opened on both sides of the test chamber 1. The protective filter plate 46 is inserted into the fixed frame 45, and the fixed frame 45 is fixed to the side wall of the test chamber 1 at the air outlet.

[0027] The specific settings and functions of this embodiment are described below: The air guide plate 41 is set as a horizontally placed "U" shape. A temperature detector 47 is set inside the test chamber 1 inside the ultraviolet lamp 3. An air duct 42 is formed between the outer side of the air guide plate 41 and the inner wall of the test chamber 1. The air duct 42 is connected to the air inlet and outlet to facilitate the flow of air inside and generate heat. Example

[0028] like Figure 1-5 As shown, the support component 5 includes a servo motor 51. The servo motor 51 is located at the center of the test chamber 1. A rotating column 52 is rotatably connected inside the test chamber 1, and the top of the rotating column 52 is fixed to the output rod of the servo motor 51. An installation cylinder 54 is sleeved on the outside of the rotating column 52. The installation cylinder 54 is a hollow hexagonal prism. Each fixed pressure plate 56 is a rectangle that cooperates with the placement groove 55. A placement groove 55 is opened on the installation cylinder 54 inside each fixed pressure plate 56. Several connecting rods 53 are fixed at equal intervals between the inner wall of the installation cylinder 54 and the outer surface of the rotating column 52. A fixed pressure plate 56 is rotatably connected to the bottom of each side of the installation cylinder 54, and the top of the fixed pressure plate 56 is fixed to the side of the installation cylinder 54 by a fixing component 6.

[0029] The overall effect of the embodiment is that the fixing component 6 includes a fixing protrusion 61 and a fixing groove 62. Each fixing plate 56 is fixed with a fixing protrusion 61 at the end away from the rotating end. The top surface of the mounting cylinder 54 is provided with a fixing groove 62 that cooperates with the fixing protrusion 61. The mounting cylinder 54 on both sides of the fixing groove 62 is provided with a moving groove 64. Each moving groove 64 is slidably fitted with a limiting block 63.

The top surface of the outer end of each moving groove 64 is set as inclined.

[0030] The usage and working principle of this device are as follows: When the ultraviolet lamp 3 is running, turn on the fan inside the fan box 43. The fan will cause the external airflow to pass through the protective filter plate 46 and enter the air duct 42, and then be discharged through the vent 44, thus dissipating heat from the ultraviolet lamp 3. When materials need to be installed, turn on the servo motor 51 to drive the placement slots 55 one by one to face the door 2. Then push the limit blocks 63 on both sides, so that the limit blocks 63 compress the springs 65 and move them into the moving slots 64. This will pull the fixing protrusions 61 out of the fixing slots 62. Then rotate the mounting cylinder 5. 4. Open the placement slot 55, put the material into the placement slot 55, and rotate the fixed pressure plate 56 in the opposite direction to clamp the material. This causes the fixed protrusion 61 to press against the limiting blocks 63 on both sides, causing the limiting blocks 63 to compress the spring 65 and move into the moving slot 64. This engages the fixed protrusion 61 into the fixed slot 62. At this time, the limiting blocks 63 move to the top surface of the fixed protrusion 61 under the push of the spring 65, thus fixing the fixed protrusion 61. During the test, the servo motor 51 drives the mounting cylinder 54 to rotate continuously, so that the material inside the placement slot 55 can receive the light source more comprehensively.

[0031] 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.
