Detailed implementation manners

[0028] In order to further explain the technical solution of the present invention, the following will be elaborated in detail through specific embodiments.

[0029] Please refer to Figure 1 , the present invention provides a test device for detecting the ultraviolet aging resistance of a coating, including a base 1. A test chamber 2 is fixedly connected to the top end of the base 1. A set of placement mechanisms 3 are installed at both the left and right ends inside the test chamber 2, and a set of adjustment mechanisms 4 are provided between the two sets of placement mechanisms 3.

[0031] Please refer to Figures 1 - 3 , a test cavity 21 is provided inside the test chamber 2. At least two sets of ultraviolet lamps 22 are installed at the front end inside the test cavity 21, which can irradiate the coating on the surface of the test plates. Openings 23 are provided at both the left and right ends of the test cavity 21. A set of cover plates 24 are hinged to the rear ends outside the two sets of openings 23. The cover plates 24 can cover the openings 23 by rotation to close the test cavity 21 and prevent external factors from affecting the test results.

[0032] Specifically, two sets of test plates can be placed into the test chamber 2 through the two sets of openings 23, and the ultraviolet aging resistance test can be carried out by the ultraviolet lamps 22 at the front end inside the test cavity 21. A control test under the same environment can be carried out to expand the test effect on different coatings.

[0033] Please refer to Figures 2 - 3, the components of the two placement mechanisms 3 are the same. The placement mechanism 3 includes a back plate 31, a rotating groove 32, a turntable 33, and a first driving motor 34. A set of back plates 31 are slidably connected to the left and right ends in the test chamber 21, and a set of back grooves 311 are opened at positions where the rear ends of the two back plates 31 are close to each other. A set of circular rotating grooves 32 are opened at positions corresponding to the two back plates 31 at the rear end in the test chamber 21. A set of turntables 33 are rotatably connected in the rotating grooves 32. A set of first driving motors 34 are installed at the left and right rear ends of the test box 2 corresponding to the two turntables 33. The front ends of the driving shafts of the first driving motors 34 penetrate and extend to be fixedly connected to the middle rear ends of the turntables 33. The rotation of the driving shafts of the first driving motors 34 can drive the turntables 33 to rotate. Among them, a set of convex rods 331 are fixedly connected to the front ends of the two turntables 33. The front ends of the convex rods 331 can extend into the back grooves 311. The rotation of the turntables 33 can push the back grooves 311 and the back plates 31 to move left and right in the test chamber 21 through the convex rods 331.

[0034] Specifically, the first driving motor 34 can drive the turntable 33 to rotate, and then through the cooperation of the convex rod 331 and the back groove 311, drive the back plate 31 to move left and right, and the back plate 31 can be moved to the outer end of the test box 2 or retracted into the test box 2, which is convenient for placing or taking out test plates.

[0035] Please refer to Figures 3 - 4 , the adjusting mechanism 4 includes a rotating shaft 41, a first gear 42, a second driving motor 43, and a linkage mechanism 44. A set of rotating shafts 41 are rotatably connected to the middle end in the test chamber 21. A set of first gears 42 are fixedly connected to the outer top ends of the rotating shafts 41. A set of second driving motors 43 are installed at the positions corresponding to the rotating shafts 41 at the top of the test box 2. The bottom ends of the driving shafts of the second driving motors 43 penetrate and extend into the test chamber 21 to be fixedly connected to the top ends of the rotating shafts 41, which can drive the rotating shafts 41 to rotate. And a linkage mechanism 44 is installed in both of the two back plates 31. Among them, the frontmost end of the first gear 42 is located at the rear of the front end face of the back plate 31, which is convenient for putting large test plates into the test box 2 and avoiding the influence on large test plates when the first gear 42 moves.

[0036] Specifically, the second driving motor 43 can drive the rotating shaft 41 and the first gear 42 to rotate, and drive the linkage mechanism 44 to move through the linkage of the first gear 42.

[0037] Please refer to Figures 4 - 6, the components of the two sets of linkage mechanisms 44 are all the same. The linkage mechanism 44 includes a support base plate 441, a connecting piece 442, a linkage chamber 443, a screw rod 444, a second gear 445, a third gear 446 and a guide rod 447. A set of support base plates 441 are provided at the front ends of the back plates 31. There are no less than two sets of card slots on the top surface of the support base plate 441, and a triangular support plate is fixedly connected to the bottom end. The card slots on the top surface of the support base plate 441 can be used to support the test plate and can adjust the inclination angle of the test plate on the support base plate 441. The rear end of the triangular support plate can contact the front end of the back plate 31 to realize the support and reinforcement of the support base plate 441. A set of connecting pieces 442 are fixedly connected to the rear left and right ends of the support base plate 441, and the rear ends of the connecting pieces 442 are all circular rings. Linkage chambers 443 corresponding to the connecting pieces 442 are provided at the front ends of the two back plates 31. A set of screw rods 444 are rotatably connected in the two linkage chambers 443 close to the rotating shaft 41. A set of second gears 445 are fixedly connected to the outer tops of the two rotating shafts 41, and one ends of the two second gears 445 close to each other are engaged with a set of third gears 446. Further, one ends of the two second gears 445 close to each other penetrate through the linkage chamber 443 and extend into the test chamber 21 to be engaged with the first gear 42. After the two back plates 31 are completely retracted into the test box 2, the first gear 42 and the third gear 446 are in contact and engaged with each other. The rotation of the first gear 42 can drive the screw rod 444 and the second gear 445 to rotate through the third gear 446, and a set of guide rods 447 are fixedly connected in the other two linkage chambers 443.

[0038] Specifically, the rotation of the first gear 42 drives the screw rod 444 and the second gear 445 to rotate through the third gear 446, and drives the support base plate 441 to move up and down through the connecting piece 442. Among them, internal threads are processed on the inner sides of the circular rings at the rear ends of the two connecting pieces 442 corresponding to the screw rod 444. The rotation of the screw rod 444 can drive the connecting piece 442 to move up and down. The thread directions on the outer sides of the left and right screw rods 444 are opposite, so that the connecting pieces 442 on the outer sides of the left and right screw rods 444 can move up and down synchronously, ensuring the synchronous movement of the two support base plates 441. The other set of connecting pieces 442 can move along the guide rod 447 to improve the movement stability of the support base plate 441.

With their mutual cooperation, two groups of test plates can be placed simultaneously to conduct batch or control tests, which can expand the test effect. Through an adjustment mechanism 4 provided between the two back plates 31, the adjustment mechanism 4 includes components such as a rotating shaft 41, a first gear 42, a second driving motor 43, and a linkage mechanism 44. With their mutual cooperation, the two linkage mechanisms 44 can be driven to move simultaneously through the first gear 42, ensuring the stability of the test and avoiding deviations.
