DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Reference Figure 1-Figure 5 The UV aging test chamber includes a test chamber 1, a hinge 3 is provided on the side wall of the test chamber 1, an upper cover 2 is rotatably mounted on the hinge 3, a handle is provided on the top wall of the upper cover 2, and a detection component is also included, including a detection table 4 installed in the test chamber 1, a lamp 5 is provided on the top wall of the detection table 4, and a plurality of partitions 6 are provided on the lamp 5. The clamping assembly includes a movable plate 7 slidably mounted on the top wall of the testing table 4, two fixed plates 8 are fixedly mounted on the top wall of the movable plate 7, two clamping plates 9 are slidably mounted on the fixed plate 8, and the two clamping plates 9 jointly clamp a plate to be tested 10, a first connecting plate 11 is connected to the clamping plate 9, the first connecting plate 11 movably passes through the outer wall of the fixed plate 8, a piston tube 12 is provided on the fixed plate 8, a piston rod 13 is movably inserted into the piston tube 12, the piston rod 13 and the first connecting plate 11 are fixedly connected, a receiving groove is provided on the top wall of the movable plate 7, a driving plate is movably mounted in the receiving groove, an auxiliary air bag is provided between the bottom wall of the driving plate and the bottom wall of the receiving groove, and a connecting tube 14 is connected between the auxiliary air bag and the piston tube 12.

[0027] In order to facilitate detection and improve the efficiency of the test, it is necessary to quickly clamp the plate to be detected 10. After opening the upper cover 2, the plate to be detected 10 is directly placed on the movable plate 7, and the plate to be detected 10 is located between the two fixed plates 8. The plate to be detected 10 squeezes the driving plate by its own gravity, and the driving plate squeezes the auxiliary airbag. The air in the auxiliary airbag enters the piston tube 12 through the connecting tube 14. The air pressure in the piston tube 12 increases, squeezing the piston rod 13 out of the piston tube 12. The two piston rods 13 drive the two first connecting plates 11 close to each other, thereby driving the two clamping plates 9 close to each other, so as to clamp the plate to be detected 10. After fixing, close the upper cover 2, start the lamp 5, and perform a light test on the plate to be detected, thereby improving the detection efficiency.

[0028] refer to Figure 1-Figure 5 The transmission assembly includes a knocking plate 15 slidably mounted on the detection table 4, and a plurality of knocking blocks 16 are provided on the knocking plate 15. A driving member is provided at the bottom of the detection table 4, and the driving member is used to drive the knocking blocks 16 to reciprocate and strike the detection table 4. The driving member includes a motor 17 arranged on the bottom wall of the test box 1, and a cam 18 is fixedly mounted on the output shaft of the motor 17. A transmission plate 19 is slidably mounted on the bottom wall of the detection table 4, and the transmission plate 19 and the cam 18 are slidably connected. The transmission plate 19 and the knocking plate 15 move synchronously. A second connecting plate 20 is fixedly mounted on the bottom wall of the knocking plate 15, and the second connecting plate 20 slides through the outer wall of the detection table 4, and a connecting rod 21 is connected between the knocking plate 15 and the transmission plate 19.

[0029] Start the motor 17, which drives the cam 18 to rotate. Due to the wavy sidewall of the cam 18, the cam 18 drives the transmission plate 19 to slide back and forth during the rotation. During the sliding process, the second connecting plate 20 is driven to slide back and forth by the connecting rod 21, thereby achieving the reciprocating impact of the knocking plate 15 and the knocking block 16 on the back side of the plate to be tested 10 (the illuminated side is the front), thereby simulating the impact in real life. The quality of the test is improved. There are multiple knocking blocks 16, and different positions can display different test results.

[0030] refer to Figure 1-Figure 5 A cleaning air bag 22 is provided on the bottom wall of the testing platform 4, a cleaning tube is provided on one side of the movable plate 7, and a plurality of air outlet holes are provided on the cleaning tube. An air outlet pipe is connected between the cleaning tube and the cleaning air bag 22, an air inlet hole is provided on the cleaning air bag 22, and a one-way valve is provided on both the air inlet pipe and the air outlet pipe.

[0031] During the reciprocating sliding of the transmission plate 19, the cleaning airbag 22 will be squeezed back and forth. The air in the cleaning airbag 22 enters the cleaning tube and blows toward the front of the plate to be tested 10, which can blow away the aging and falling materials, thereby simulating the wind blowing conditions in real situations.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
