The two sliders are fixed by a linkage tube. The linkage tube is threadedly sleeved on the outer surface of the power screw shaft. Both ends of the slider are elastically connected to the detection placement plate. One end of the power screw shaft located outside the detection placement plate is rotatably connected to the detection outer box.

[0006] On one side of the detection placement board, there is a detection lamp that can move back and forth. On the other side of the detection placement board, there is a power supply block that can move back and forth. The detection lamp and the power supply block are arranged inside the detection outer box. The detection outer box is provided with an observation port, and a rotatable and openable glass sealing plate is installed at the observation port on the outer side of the detection outer box.

[0007] Optionally, placement grooves are formed on the upper surface of the detection placement board. The placement grooves are distributed in two groups with equal quantity and equal distance on the inner and outer sides of the detection outer box. Notches that cooperate with the detection lamp and the power supply block are respectively formed at the front and rear ends of the placement grooves. Elastic clamping plates A that can be deformed are installed on the inner walls of the left and right sides of the placement grooves, and elastic clamping plates B that can be deformed are installed on the inner walls of the front and rear sides of the placement grooves and on both sides of the notches.

[0008] Optionally, through grooves are respectively formed on the left and right side surfaces of the detection outer box at the penetration position of the detection placement board. The detection placement board is located inside the through grooves. Both ends of the detection placement board are plate-shaped structures, and the cross-section of the plate-shaped structure of the detection placement board is larger than the cross-section of the through grooves.

[0009] Optionally, balance springs are fixed at both ends of the slider. The other ends of the balance springs are fixed to the detection placement board. The power threaded shaft and the linkage tube are both located inside the balance springs.

[0010] Optionally, a dial plate is fixed to the bottom surface of the slider. The lower end of the dial plate is located above the inner bottom wall of the through groove. A bidirectional threaded rod is arranged below the detection placement board. Both ends of the bidirectional threaded rod are rotatably connected to the inner wall of the detection outer box. Torsion springs are installed at both the front and rear ends of the bidirectional threaded rod, and the torsion springs are fixed to the inner wall of the detection outer box. Two meshing structures are threadedly sleeved on the outer surface of the bidirectional threaded rod. The detection lamp and the power supply block are respectively connected to the two meshing structures. A winding wheel is fixedly sleeved between the two meshing structures on the bidirectional threaded rod. A pull rope is wound and connected to the outer surface of the winding wheel. The upper end of the pull rope is fixed to a horizontal force-bearing rod, and the horizontal force-bearing rod is arranged inside the detection outer box and can slide left and right.

[0011] Optionally, horizontal sleeve frames are slidably sleeved at both ends of the horizontal force-bearing rod. The horizontal sleeve frames are fixedly inserted inside the detection outer box. The upper end of the horizontal force-bearing rod is located above the lower end of the dial plate.

[0012] Optionally, the meshing structure includes a meshing ring, a strip plate, and a connecting spring. The bidirectional threaded rod is located inside the inner ring side of the connecting spring. Both ends of the connecting spring are respectively fixed to the meshing ring and the strip plate. The meshing ring is threadedly sleeved on the outer surface of the bidirectional threaded rod. The detection lamp and the power supply block are respectively fixed to the adjacent strip plates.

[0013] Optionally, two steering wheels are arranged above the winding wheel. Both ends of the steering wheels are rotatably connected to the inner wall of the detection outer box. The pull rope is located between the two steering wheels, and the steering wheels are located below the horizontal force-bearing rod.

[0014] Optionally, an exhaust fan that can communicate inside and outside is installed on the surface of the detection outer box, and a smoke detection controller is installed through the surface of the detection outer box.

[0015] A power adapter detection method includes the following steps:

[0016] S1. Place the power adapter to be detected in the placement slot of the detection placement board. When the power threaded shaft rotates, it drives two sliders to move by meshing with the linkage tube.

[0017] S2. When the slider moves, it drives the detection placement board to move through elastic connection, and moves the end with the power adapter placed into the detection outer box.

[0018] S3. Control the detection lamp and the power supply block to be connected to the power adapter. The power supply block supplies power to the power adapter. After the detection lamp is connected to the power adapter, observe whether it is bright to detect whether the power adapter is qualified.

[0019] S4. When detecting the power adapter, a new power adapter to be detected can be placed on the detection placement board outside the detection outer box, and a new power adapter to be detected can be placed while detecting.

[0020] S5. Then after the detection is completed, control the detection placement board to move, move the end of the detection placement board with the new power adapter into the detection outer box, and at the same time move the power adapter after detection to the outside of the detection outer box.

[0021] In summary, the present invention includes the following beneficial technical effects:

[0022] 1. By setting components such as the detection placement board, sliders, linkage tube, and power threaded shaft, the power threaded shaft can drive the sliders to reciprocate left and right by meshing with the linkage tube during forward and reverse rotation. The detection placement board moves left and right following the sliders. When detecting the power adapter placed at one end of the detection placement board inside the detection outer box, the power adapter to be detected can be placed above the end of the detection placement board outside the detection outer box. Then, during the movement of the detection placement board, the power adapter located outside can be moved into the detection outer box, and at the same time, the power adapter inside the detection outer box can be moved to the outside of the detection outer box, reducing the time wasted when placing the power adapter.

[0023] 2. The present invention is provided with components such as a bidirectional threaded rod, a torsion spring, a pull rope, a dial plate, and a horizontal force-bearing rod. After the plate-like structure at one end of the detection placement plate contacts the outer surface of the detection outer box, the detection prevention plate stops moving in the same direction. Then, when the slider continues to move, the horizontal force-bearing rod is pushed by the dial plate, the pull rope is pulled out from the winding wheel, driving the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it meshes with two engagement rings, pulling two strip plates closer to each other, driving the power supply block and the detection lamp closer to the power adapter in the placement groove. The power supply block and the detection lamp are connected to the power adapter inside the detection outer box. Then, when the slider moves in the reverse direction, it drives the dial plate to move in the reverse direction. The bidirectional threaded rod drives the winding wheel to rewind the pull rope under the action of the torsion spring, and at the same time pulls the power supply block and the detection lamp away from the detected power adapter.

[0024] 3. The present invention is provided with a placement groove, elastic clamping plate A, and elastic clamping plate B. The power adapter to be detected is placed in the placement groove, and at the same time, the power adapter is placed between two elastic clamping plate As and four elastic clamping plate As in the placement groove, limiting the position of the power adapter in the placement groove, so that the power supply block and the detection lamp can be accurately connected to the power adapter when moving.

Detailed implementation mode

[0034] The following will Figures 1 - 8 further elaborate on the present invention in conjunction with the attached drawings.

[0035] An embodiment of the present invention discloses a power adapter detection device. As Figures 1 - 8 shown, it includes a detection outer box 1. An exhaust fan 12 that can communicate inside and outside is installed on the surface of the detection outer box 1. A smoke detection controller 13 is installed through the surface of the detection outer box 1. When a short circuit occurs during the detection of the power adapter and the power adapter smokes, when the smoke detection controller 13 detects the smoke, it controls the exhaust fan 12 to rotate, and at the same time reduces the temperature inside the detection outer box 1 to prevent danger caused by excessive smoke and high temperature inside the detection outer box 1 when a short circuit occurs in the power adapter.

[0036] A slidable detection placement plate 2 penetrates through the side surface of the detection outer box 1. A placement groove 9 is opened on the upper surface of the detection placement plate 2. The placement grooves 9 are distributed in two groups with equal quantity and equal distance on the inner and outer sides of the detection outer box 1. Elastic clamping plates A91 that can deform are installed on the inner walls of the left and right sides of the placement groove 9. Elastic clamping plates B92 that can deform are installed on the inner walls of the front and back sides of the placement groove 9 and on both sides of the notch. The power adapter to be detected is placed in the placement groove 9, so that the power adapter is located between the elastic clamping plates A91 and the elastic clamping plates B92, and the position of the power adapter in the placement groove 9 is limited.

[0037] Through slots 11 are opened on the left and right side surfaces of the detection outer box 1 at the penetration position of the detection placement plate 2. The detection placement plate 2 is located inside the through slots 11. Both ends of the detection placement plate 2 are plate-shaped structures, and the cross-section of the plate-shaped structure of the detection placement plate 2 is larger than the cross-section of the through slots 11. When the plate-shaped structure of the detection placement plate 2 contacts the surface of the detection outer box 1, the detection placement plate 2 can no longer move in the same direction, and the moving distance of the detection placement plate 2 relative to the detection outer box 1 is limited.

[0038] Inside the detection placement plate 2, there is a power threaded shaft 3 that can rotate relatively. The outer end of the power threaded shaft 3 is connected to a motor to output power to the power threaded shaft 3. A slidable slider 4 is inserted into the bottom surface of the detection placement plate 2. Two sliders 4 are fixed by a linkage pipe 5. The linkage pipe 5 is threadedly sleeved on the outer surface of the power threaded shaft 3. The two ends of the slider 4 are elastically connected to the detection placement plate 2. Balance springs 41 are fixed at both ends of the slider 4. The other ends of the balance springs 41 are fixed to the detection placement plate 2. The power threaded shaft 3 and the linkage pipe 5 are both located inside the balance springs 41. The outer end of the power threaded shaft 3 located outside the detection placement plate 2 is rotatably connected to the detection outer box 1. The power threaded shaft 3 that rotates forward and backward can drive the slider 4 to move left and right by meshing with the linkage pipe 5.

[0039] On one side of the detection placement plate 2, there is a detection lamp 10 that can move back and forth. On the other side of the detection placement plate 2, there is a power supply block 6 that can move back and forth. Notches that match the detection lamp 10 and the power supply block 6 are respectively opened at the front and rear ends of the placement groove 9, so that the detection lamp 10 and the power supply block 6 can be inserted into the placement groove 9 from the notches when moving.

[0040] A dial plate 42 is fixed to the bottom surface of the slider 4. The lower end of the dial plate 42 is located above the inner bottom wall of the through groove 11. A bidirectional threaded rod 43 is arranged below the detection placement plate 2. Both ends of the bidirectional threaded rod 43 are rotatably connected to the inner wall of the detection outer box 1. Torsion springs 44 are installed at both the front and rear ends of the bidirectional threaded rod 43. The torsion springs 44 are fixed to the inner wall of the detection outer box 1. Two meshing structures 45 are threadedly sleeved on the outer surface of the bidirectional threaded rod 43. The detection lamp 10 and the power supply block 6 are respectively connected to the two meshing structures 45.

[0041] The meshing structure 45 includes a meshing ring 451, a strip plate 452, and a connecting spring 453. The bidirectional threaded rod 43 is located inside the inner ring side of the connecting spring 453. Both ends of the connecting spring 453 are respectively fixed to the meshing ring 451 and the strip plate 452. The meshing ring 451 is threadedly sleeved on the outer surface of the bidirectional threaded rod 43. The bidirectional threaded rod 43 rotating forward and backward can respectively drive the two meshing rings 451 to approach or move away from each other. The detection lamp 10 and the power supply block 6 are respectively fixed to the adjacent strip plates 452.

[0042] A bidirectional threaded rod 43 is fixedly sleeved with a winding wheel 46 between two meshing structures 45. A pull rope 47 is wound and connected to the outer surface of the winding wheel 46. The upper end of the pull rope 47 is fixed with a horizontal force-bearing rod 48. The horizontal force-bearing rod 48 is arranged inside the detection outer box 1 and can slide left and right. When the slider 4 moves and drives the plate-like structure of the detection placement plate 2 to contact the detection outer box 1, and then when the slider 4 continues to move in the same direction, the slider 4 compresses the balance spring 41. The slider 4 pushes the horizontal force-bearing rod 48 through the dial plate 42, pulls out the pull rope 47 from the surface of the winding wheel 46, drives the bidirectional threaded rod 43 to rotate, and drives the torsion spring 44 to twist and store energy. When the bidirectional threaded rod 43 rotates, it can drive the two meshing rings 451 to approach each other by meshing with the two meshing rings 451. Through the strip plate 452, the detection lamp 10 can be driven to be connected to the power supply block 6 and the power adapter for detection. For a normal power adapter, when the power supply block 6 is connected to the power adapter, the power adapter makes the detection lamp 10 emit light. Then, when the slider 4 drives in the reverse direction, the torsion spring 44 has a tendency to wind the pull rope 47 through the bidirectional threaded rod 43. During the gradual movement of the slider 4, the winding wheel 46 gradually winds the pull rope 47.

[0043] There are two turning wheels 461 arranged above the winding wheel 46. Both ends of the turning wheels 461 are rotatably connected to the inner wall of the detection outer box 1. The pull rope 47 is located between the two turning wheels 461. The turning wheels 461 are located below the horizontal force-bearing rod 48, and the turning wheels 461 limit the turning position of the pull rope 47.

[0044] Both ends of the horizontal force-bearing rod 48 are slidably sleeved with horizontal sleeve frames 481. The horizontal sleeve frames 481 are fixedly inserted inside the detection outer box 1. The upper end of the horizontal force-bearing rod 48 is above the lower end of the dial plate 42. The horizontal sleeve frames 481 enable the horizontal force-bearing rod 48 to only have a horizontal tendency.

[0045] The detection lamp 10 and the power supply block 6 are arranged inside the detection outer box 1. The detection outer box 1 is provided with an observation port 7. A rotatable and openable glass cover plate 8 is installed at the position of the observation port 7 on the outside of the detection outer box 1. The glass cover plate 8 is transparent, and the internal situation of the detection outer box 1 can be observed through the glass cover plate 8 and the observation port 7.

[0046] The power adapter detection method includes the following steps:

[0047] S1. Place the power adapter to be detected in the placement groove 9 of the detection placement plate 2. When the power threaded shaft 3 rotates, it drives the two sliders 4 to move by meshing with the linkage tube 5.

[0048] S2. When the slider 4 moves, it drives the detection placement plate 2 to move through elastic connection, and moves the end with the power adapter into the detection outer box 1.

[0049] S3. Control the detection lamp 10 and the power supply block 6 to be connected to the power adapter. The power supply block 6 supplies power to the power adapter. After the detection lamp 10 is connected to the power adapter, check whether the power adapter is qualified by observing whether it is bright.

[0050] S4. When detecting the power adapter, the new power adapter to be detected can be placed on the detection placement board 2 outside the detection outer box 1, and a new power adapter to be detected can be placed while detecting.

[0051] S5. Then, after the detection is completed, control the detection placement board 2 to move, move one end of the detection placement board 2 with the new power adapter into the detection outer box 1, and at the same time move the power adapter after the detection to the outside of the detection outer box 1.

[0052] The working principle is as follows: The linkage pipe 5 moves left and right by meshing with the power screw shaft 3 that rotates forward and backward. The linkage pipe 5 drives the two sliders 4 to move synchronously. The sliders 4 drive the detection placement board 2 to move synchronously through elastic connection. The power adapter to be detected is located on the detection placement board 2. When detecting the power adapter placed at one end of the detection placement board 2 inside the detection outer box 1, a new power adapter to be detected can be placed above the outer end of the detection placement board 2 outside the detection outer box 1. Then, during the movement of the detection placement board 2, the power adapter located outside can be moved into the detection outer box 1, and at the same time, the power adapter inside the detection outer box 1 can be moved to the outside of the detection outer box 1. When the detected adapter can be removed and a new power adapter can be put in, the power adapter inside the detection outer box is detected.

[0053] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
