DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 A switching power supply automatic aging test device includes a base plate 1, a testing mechanism 2, an adjusting mechanism 3 and a sealing mechanism 4. The testing mechanism 2 is arranged on the top of the base plate 1, the adjusting mechanism 3 is arranged on the top of the base plate 1, and the sealing mechanism 4 is arranged on the top of the testing mechanism 2.

[0021] The testing mechanism 2 includes a fixed shell 21 and a rolling bearing 22. The fixed shell 21 is installed on the top of the shell 1. The top of the inner wall of the fixed shell 21 is fixedly connected to the tester body 23. The rolling bearing 22 is installed in the groove on the top of the base plate 1 and is located inside the fixed shell 21. A fixed shaft 24 is movably connected to the inner wall of the rolling bearing 22. The top of the fixed shaft 24 is fixedly connected to a workbench 25. A placement groove 26 is provided on the top of the workbench 25. There are four placement grooves 26 and they are equidistantly arranged on the top of the workbench 25. Through the mutual cooperation of the rolling bearing 22, the fixed shaft 24, the workbench 25 and the placement grooves 26, multiple switching power supplies can be placed, thereby greatly improving the efficiency of the test.

[0022] The adjusting mechanism 3 includes a supporting shell 31. There are four supporting shells 31 and they are respectively installed at the four corners of the bottom of the base plate 1. A threaded rod 32 is threadedly connected to the inner wall of the supporting shell 31. The bottom end of the threaded rod 32 passes through the supporting shell 31 and extends to the outside thereof. The bottom end of the threaded rod 32 is fixedly connected to a supporting block 33. When adjustment is required, the supporting block 33 is rotated, and the supporting block 33 drives the threaded rod 32 to rotate in the supporting shell 31 to adjust the height. Through the mutual cooperation of the supporting shell 31, the threaded rod 32 and the supporting block 33, the height of the test device can be easily adjusted, thereby ensuring that the test device is in a horizontal state.

[0023] The sealing mechanism 4 includes a fixed plate 41, which is arranged at the top of the fixed shell 21. A fixed groove 42 is opened on the front of the fixed plate 41. The rear side of the inner wall of the fixed groove 42 is fixedly connected with a buffer spring 43. The front end of the buffer spring 43 is fixedly connected with a movable plate 44. As shown in the figure, the buffer spring 43 at this time has the force to drive the movable plate 44 to move backward. The side of the movable plate 44 close to the inner wall of the fixed groove 42 is slidably connected to the inner wall of the fixed groove 42. The front side of the movable plate 44 is fixedly connected with a connecting block 45. The front side of the connecting block 45 passes through the fixed groove 42 and extends to the outside thereof. The front side of the connecting block 45 is fixedly connected with a movable plate 46. The side of the movable plate 46 close to the fixed plate 41 contacts the fixed plate 41. The front side of the movable plate 46 is fixedly connected with a pull ring 47. A sealing plate 48 is provided at the top of the fixed plate 41 and located on the front side of the fixed shell 21. The bottom of the sealing plate 48 passes through the fixed plate 41 and extends to the outside thereof. The sealing plate 48 is in contact with the fixed shell 21 on one side thereof, and the sealing plate 48 is made of rubber. The top of the back of the movable plate 46 is fixedly connected to the limiting plate 49. The limiting plate 49 passes through the sealing plate 48 on one side thereof and extends to its inside and contacts the inner wall of the sealing plate 48. The size of the sealing plate 48 matches the size of the fixed shell 21. Because the length of the sealing plate 48 is long, when the sealing plate 48 completes the sealing of the fixed shell 21, the limiting plate 49 can also maintain the state of contact with the sealing plate 48. Through the cooperation of the fixed plate 41, the fixing groove 42, the buffer spring 43, the movable plate 44, the connecting block 45, the movable plate 46, the pull ring 47, the sealing plate 48 and the limiting plate 49, the test device can be sealed when it is not needed, thereby preventing external dust from covering the test device, thereby avoiding affecting the next use of the test device, and bringing great convenience to the user.

[0024] During use, the switching power supply is placed in the placement slot 26. When the test of one switching power supply is completed, the workbench 25 can be rotated to move the next switching power supply to the position to be tested. When the later test device is not needed, the pull ring 47 is pulled forward. The pull ring 47 drives the connecting block 45 to move forward through the movable plate 46. The connecting block 45 moves by stretching the buffer spring 43 through the movable plate 44. The movable plate 46 drives the limit plate 49 and the sealing plate 48 to separate. When the limit plate 49 and the sealing plate 48 are separated, the sealing plate 48 moves downward due to the gravity of the sealing plate 48 itself, thereby sealing the fixed shell 21.

[0025] To sum up: the automatic aging test device for the switching power supply solves the problems raised in the above-mentioned background technology through the mutual cooperation of the rolling bearing 22, the fixed shaft 24, the workbench 25 and the placement groove 26, and the mutual cooperation of the fixed plate 41, the fixed groove 42, the buffer spring 43, the movable plate 44, the connecting block 45, the movable plate 46, the pull ring 47, the sealing plate 48 and the limit plate 49.
