[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-6 As shown, a PD power supply protection device includes a housing 1 for accommodating a PD power supply 7 and a waterproof connector 2 arranged on an inner wall of one side of the housing 1 .

[0033] The waterproof joint 2 includes a shell 3, a fixed plate 8 and a slide plate 10. A slide groove 11 and an avoidance groove 6 interconnected with the slide groove 11 are opened in the shell 3. The fixed plate 8 is fixed to the side wall of the shell 3. The slide plate 10 is movably fitted in the slide groove 11. Slots 13 are opened on both sides of the inner wall of the fixed plate 8. A slot 2 14 is opened on the inner wall of the slide plate 10, and the slots 13 and 14 are staggered.

[0034] When the device is not in use, slot one 13 and slot two 14 are offset from each other, so that the device is in a closed state as a whole. When the device is in use, the slide plate 10 is adjusted so that slot one 13 and slot two 14 overlap each other, so that the device can be used normally for fast charging.

[0035] The device is provided with slot one 13 and slot two 14. When slot one 13 and slot two 14 overlap each other, the device can be used normally to provide the user with a fast charging function. When slot one 13 and slot two 14 are misaligned with each other, the device is in a closed state as a whole, thereby preventing water and dust from entering the interior of the device and causing damage to the internal and electronic components, thereby protecting the performance of the PD power supply 7 and extending its service life.

[0036] In this embodiment, the side wall of the slide plate 10 is fixedly connected with a connecting rod 9, and a thread groove 15 is formed on the outer wall of the connecting rod 9. The avoidance groove 6 is limited and matched with the thread groove 15 through a limiting column 16 provided on the side wall.

[0037] The side wall of the slide groove 11 is buckled with a spring 12 , and the other end of the spring 12 contacts and fits with the side wall of the slide plate 10 .

[0038] The inner wall of the shell 3 is also provided with a receiving groove 5 , and the number of the receiving groove 5 , the slot 1 13 and the slot 2 14 is the same, and the power connection limit assembly 4 is arranged in the receiving groove 5 .

[0039] After inserting the plug of the electronic device that needs to be powered into slot 13, the plug contacts the surface of the slide plate 10, and then the plug is continued to be pushed, and the slide plate 10 is used to drive the connecting rod 9 to move in the avoidance groove 6. The spring 12 is compressed by the force, and due to the limitation of the threaded groove 15 and the limiting column 16, the connecting rod 9 moves and drives the slide plate 10 to rotate, until the slot 2 14 rotates to coincide with the receiving groove 1 5 and the slot 1 13. At this time, the plug is located in the receiving groove 1 5, and the device can conduct electricity. After use, the plug is pulled out, and the spring 12 uses its own elasticity to push the slide plate 10 to reset. The threaded groove 15 and the limiting column 16 guide the connecting rod 9 to rotate again, so that the connecting rod 9 drives the slide plate 10 to rotate, thereby misaligning the slot 2 14 and the slot 1 13.

[0040] Embodiment 2:

[0041] A PD power supply protection device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-4 As shown:

[0042] The power-on limiting assembly 4 includes a terminal 18 fixed to the inner wall of the accommodating groove 1 5 and two symmetrically arranged metal springs 17 , and the terminal 1 18 is electrically connected to the PD power supply 7 .

[0043] Insert the plug of the electronic device that needs to be powered into the receiving slot 1 5. The plug first passes between the two metal springs 17. The metal springs 17 are used to clamp the plug. When the plug contacts the terminal 18, the device can conduct electricity.

[0044] The device is provided with two symmetrically arranged metal springs 17, and utilizes the characteristics of the metal springs 17 so that when the electronic device plug is inserted between the two metal springs 17, the metal springs 17 exert pressure on the plug, thereby clamping and fixing the plug to prevent it from shifting during use, thereby ensuring the continuous and stable output of current and the normal operation of the device.

[0045] Embodiment 3:

[0046] A PD power supply protection device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 5 and Figure 6 As shown:

[0047] The power-on limiting assembly 4 includes a fixed block 19 and two symmetrically arranged limiting plates 20 . The fixed block 19 is fixedly connected to the inner wall of the accommodating groove 1 5 , and the inner wall of the connecting rod 9 is provided with two symmetrically arranged sliding grooves 21 .

[0048] The side walls of the two limit plates 20 are fixedly connected with a slider 23 , and the slider 23 is slidably fitted in the second slide groove 21 , and the second spring 22 is buckled on the opposite side of the second slide groove 21 and the slider 23 .

[0049] The side wall of the fixing block 19 located at the limiting plate 20 is provided with a second terminal 24 , and the second terminal 24 has a second receiving groove 25 therein, and the second receiving groove 25 is electrically connected to the PD power supply 7 .

[0050] Insert the plug of the electronic device that needs to be powered into the receiving slot 1 5. The plug first passes between the two limit plates 20, and the two limit plates 20 are pushed to both sides. At this time, the two springs 22 are both elastically deformed under force and provide pressure to the two limit plates 20 respectively, so that the two springs 22 clamp the plug. When the plug contacts the terminal 2 24, the device can conduct electricity.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
