Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic pipe durability testing technology, specifically to a plastic pipe durability testing device. Background Technology
[0002] In the durability testing of plastic pipes, ultraviolet (UV) aging test chambers are used to simulate UV irradiation in the natural environment to test the aging resistance of plastic pipes. The UV aging test chamber simulates a UV irradiation environment to test the UV aging resistance of plastic pipes. UV lamps inside the equipment emit UV light of a specific wavelength, irradiating the plastic pipes. After a certain period, the color change, surface cracking, and degree of degradation of mechanical properties of the plastic pipes are observed to assess their aging resistance in outdoor environments.
[0003] However, existing UV aging test chambers generally lack convenient sample rotation devices, making it difficult to achieve multi-angle irradiation of the sample. During the test, only a portion of the sample surface can receive UV irradiation, failing to simultaneously cover the entire sample surface. This results in insufficient aging testing, further reducing the reliability and validity of the test results, and failing to meet the need for accurate evaluation of the durability of plastic pipes.
[0004] Therefore, a durability testing device for plastic pipes is proposed. Utility Model Content

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a plastic pipe durability testing device includes an aging test chamber 1. The surface of the aging test chamber 1 is provided with auxiliary components 2. Multiple reflectors 3, each arc-shaped, are provided on the top surface of the inner wall of the aging test chamber 1. The inner wall of the reflectors 3 is provided with a high-reflectivity mirror coating 4. An ultraviolet lamp 5 is provided on the inner wall of the reflectors 3. A driving component 6 and a driven component 7 are provided inside the aging test chamber 1. A turntable 8 is fixedly connected to the surface of the driven component 7. A fixing component 9 for fixing plastic pipe samples is provided on the surface of the turntable 8. The surface of the fixed component 9 is provided with rubber toothed blocks 10, and the surface of the aging test chamber 1 is provided with a control panel 11. Specifically, in this plastic tube durability testing equipment, the reflector 3 is set up so that while the high reflectivity mirror coating 4 is installed, the arc shape has unique optical characteristics, which can efficiently focus the light emitted by the ultraviolet lamp 5. The arc-shaped reflector 3, together with the high reflectivity mirror coating 4, can make the light more evenly distributed inside the chamber. The high reflectivity mirror coating 4 has extremely high reflectivity, which can reflect as much light as possible to all corners inside the chamber, reducing light loss. The drive component 6 and the driven component 7 are set up so that the drive component 6 can drive the turntable 8 to rotate synchronously through the drive component 7. The fixed component 9 and the rubber toothed blocks 10 on the turntable 8 can clamp and install the plastic tube sample, so that the plastic tube sample can be rotated and adjusted when irradiated, so that the surface of the plastic tube sample can receive more uniform ultraviolet irradiation.
[0026] like Figure 1 As shown, the auxiliary component 2 includes a door 201. The surface of the aging test chamber 1 is provided with a door 201, and the surface of the door 201 is provided with an observation window 202. A heat dissipation vent 203 is provided on the side of the aging test chamber 1. Specifically, the auxiliary component 2 is configured such that the door 201 is hinged to the aging test chamber 1 for easy opening and closing; the observation window 202 is provided on the door 201, allowing the operator to observe the test situation without opening the door 201; and the heat dissipation vent 203 is provided on the side of the aging test chamber 1 for heat dissipation of the internal structure during equipment operation.
[0027] like Figure 2 As shown, the drive assembly 6 includes a mounting slot 601. The mounting slot 601 is provided inside the aging test chamber 1, and a motor 602 is fixedly connected to the inner wall of the mounting slot 601. Specifically, the drive assembly 6 is configured such that the mounting slot 601 is located on the side of the aging test chamber 1, the motor 602 is installed in the mounting slot 601, and its output shaft is connected to the driven assembly 7 to provide power for the rotation of the driven assembly 7.
[0028] like Figure 2 , Figure 3As shown, the driven component 7 includes a rotating spindle 701, which is rotatably connected inside the aging test chamber 1. The output end of the motor 602 is fixedly connected to the rotating spindle 701, and the turntable 8 is fixedly connected to the rotating spindle 701. A driven rod 702 is rotatably connected inside the aging test chamber 1, and the turntable 8 is fixedly connected to the driven rod 702. A synchronous belt structure 703 is provided on the surface of the rotating spindle 701 and the surface of the driven rod 702. Specifically, one end of the rotating spindle 701 is connected to the output shaft of the motor 602, and the surface of the rotating spindle 701 and the driven rod 702 are connected by the synchronous belt structure 703. Turntables 8 are fixed on both the rotating main shaft 701 and the driven rod 702. When the motor 602 runs, it can drive the rotating main shaft 701 and the driven rod 702 to rotate synchronously, thereby driving the turntables 8 to rotate. The turntables 8 can fix the plastic tube sample through the fixing component 9 and the rubber tooth block 10, that is, drive the plastic tube sample to adjust the angle.
[0029] like Figure 2 , Figure 3 As shown, the fixing component 9 includes a connecting block 901. The connecting block 901 is fixedly connected to the surface of the turntable 8. A threaded moving rod 902 is threadedly connected to the connecting block 901. An upper clamping block 903 is rotatably connected to the bottom end of the threaded moving rod 902. A lower clamping block 904 is fixedly connected to the surface of the turntable 8, and a rubber toothed block 10 is disposed on the surface of the lower clamping block 904. Specifically, the fixing component 9 is configured such that the connecting block 901 is fixed to the turntable 8, the threaded moving rod 902 is threadedly connected to the connecting block 901, the upper clamping block 903 is rotatably connected to the threaded moving rod 902, and the lower clamping block 904 is fixed to the connecting block 901. By rotating the threaded moving rod 902, the upper clamping block 903 can be moved closer to or away from the lower clamping block 904, thereby achieving the clamping and loosening of the sample, adapting to samples of different specifications. With the setting of the rubber toothed block 10, the plastic tube sample can be clamped and fixed more stably.
[0030] like Figure 1 , Figure 2 As shown, motor 602 is a servo motor that can rotate in both directions. Its rotation speed and rotation angle can be precisely controlled through control panel 11. Specifically, the ability to rotate in both directions allows the sample to rotate in both directions. Combined with the function of precisely controlling the rotation angle, the sample can be uniformly irradiated with ultraviolet light at all angles within a 360° range.
[0031] In summary: Test operation: Open the chamber door 201, place the plastic product sample to be tested on the lower clamping block 904, and rotate the threaded moving rod 902 to firmly clamp the sample with the upper clamping block 903. Close the chamber door 201, set the rotation speed of the motor 602 through the control panel 11 (e.g., set it to 5 revolutions per minute), and turn on the ultraviolet lamp 5. The ultraviolet rays emitted by the ultraviolet lamp 5 are reflected by the high reflectivity mirror coating 4 inside the reflector 3, and evenly irradiate the sample inside the chamber. The motor 602 drives the rotating spindle 701 to rotate, and the rotating spindle 701 drives the driven rod 702 to rotate through the synchronous belt structure 703, thereby causing the turntable 8 and the sample fixed on it to rotate, so that the sample receives ultraviolet irradiation evenly at different angles. During the test, the operator can observe the changes in the sample through the observation window 202. After the test, turn off the ultraviolet lamp 5 and the motor 602, open the chamber door 201, rotate the threaded moving rod 902 to release the upper clamping block 903, and take out the sample for subsequent performance testing and analysis.
