The power adapter pin protection device is a device designed to protect the power adapter pins from damage and contamination. This device not only enhances the safety of the power adapter pins, but also improves the convenience of use.

[0003] For example, the Chinese patent "CN219041612U" discloses a power adapter using a pin protection component, which proposes that: the right side of the adapter body is fixedly connected with a pin, the left side of the adapter body is fixedly connected with a power cord, the four walls of the adapter body are provided with a protection component, and the protection component includes a protection sleeve and a spring provided inside the protection sleeve. The utility model relates to the technical field of power adapters. The power adapter using the pin protection component is provided with a corrugated sleeve on the outside of the adapter body, and the protection component is provided so that the corrugated sleeve can be moved and retracted left and right. When the adapter is plugged in, the corrugated sleeve can be moved to the left to expose the pin, and when not in use, the corrugated sleeve can cover the pin to achieve a protective effect. By providing a rotatable L-shaped clip, the elastic force of the arc-shaped spring sheet is used to drive the rotating shaft to rotate, which can play a fixing effect after the telescopic rod enters the protective sleeve, and prevent the corrugated sleeve from popping out and affecting the plug-in stability.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-3 A power adapter pin protection device includes a power adapter 1, a power cord 11 is arranged on the outer wall of the power adapter 1, the power cord 11 connects the power adapter with an external power supply to ensure a stable power supply, a groove is opened on the outer wall of the power adapter 1, a pin assembly 2 is arranged inside the groove of the power adapter 1, and a protection assembly 3 is arranged outside the groove of the power adapter 1.

[0034] See also Figure 4-5The pin assembly 2 includes a pin slide 21, and the two pin slides 21 are arranged on both sides of the inner groove of the power adapter 1, providing a moving space and track for the pin plate 26 and the bevel slider 25. The bevel slider 25 is movably installed inside the pin slide 21. The design of the pin slide 21 ensures the stability and smoothness of the pin plate 26 when moving. The outer walls of the two bevel sliders 25 are fixedly connected with the pin plate 26, and the outer wall of the pin plate 26 is provided with a limiting groove 27. The outer wall of the pin slide 21 is provided with a card ball base 22, and a support spring 23 is arranged inside the card ball base 22. The outer wall of the support spring 23 is fixedly connected with a card ball 24, and the support spring 23 and the inner wall of the pin slide 21 are secured. Hold a distance of a beveled slider 25, the outer wall of the beveled slider 25 and the contact surface of the locking ball 24 are inclined surfaces, when the pin plate 26 slides downward to the bottom, the beveled slider 25 will compress the support spring 23 and push the locking ball 24 to move inward, thereby allowing the pin plate 26 to continue to move downward, when the pin plate 26 moves to the shortest point of the pin slide groove 21, the beveled slider 25 will release the support spring 23, and the locking ball 24 will pop outward under the action of the spring force, interact with the surface of the beveled slider 25, and realize the locking of the pin plate 26. The outer wall of the pin plate 26 is provided with a pin 28, and when the pin plate 26 moves to the bottom of the pin slide groove 21, the pin 28 is completely retracted into the power adapter 1.

[0035] See also Figure 3 , Figure 4 , Figure 6 The protection component 3 includes a protection plate slide 31 and a pull plate 32. The outer wall of the pull plate 32 is fixedly connected to a pull rod 33. The user can operate the movement of the pull rod 33 by pulling the pull plate 32. A fixing plate 35 is fixedly installed on the outer wall of the pull rod 33. The fixing plate 35 can be engaged and installed inside the limiting groove 27. When the fixing plate 35 is engaged with the limiting groove 27, it can fix the position of the pin plate 26 to prevent the pin plate 26 from sliding. The two protection plate slides 31 are fixedly installed on both sides of the outer wall of the groove of the power adapter 1. Slide plates 36 are movably installed inside the protection plate slides 31 on both sides. The design of the protection plate slide 31 ensures the stability and smoothness of the slide plate 36 when moving. The outer wall of the slide plate 36 is fixed A protective panel 37 is fixedly installed, and the size of the protective panel 37 is consistent with the size of the groove of the power adapter 1. When the slide plate 36 moves, the protective panel 37 can cover or expose the groove of the power adapter 1. The design of the protective panel 37 can effectively prevent the pins from being damaged or contaminated by the outside world when not in use. The fixed plate 35 is made of elastic rubber material, which has a certain strength and durability, and can provide the necessary elasticity and buffer when needed, while increasing friction to prevent loosening or falling off when limiting. The outer wall of the pull rod 33 is sleeved with a tension spring 34, and the tension spring 34 is arranged between the fixed plate 35 and the protective plate slide groove 31, and the pull rod 33 is movably installed on the inner surface of the slide groove 31.

[0036] See also Figure 2-4 A pressing plate 4 is arranged above the pin plate 26. This design enables the user to easily control the expansion of the pins without directly touching the pins. The pressing plate 4 is movably installed in the slide groove opened on the outer wall of the power adapter 1. The upper and lower ends of the pressing plate 4 are provided with limit plates larger than the slide groove. The function of these limit plates is to prevent the pressing plate 4 from excessively moving in the slide groove or escaping from the slide groove.

[0037] Working principle: First, when the power adapter is not in use and needs to be carried, the user can first pull the pull plates 32 on both sides to make the pull rod 33 drive the fixing plate 35 to fall off from the limit grooves 27 on both sides of the pin plate 26. After the fixing plate 35 falls off, the user presses the pin 28 to push the pin 28 into the power adapter 1. The pin 28 slides into the pin slide groove 21 through the beveled sliders 25 on both sides of the pin plate 26. After the pin plate 26 slides inward, the inclined edges of the beveled sliders 25 on both sides push the card ball 24 to move inward to keep the pin plate 26 from continuing to move. When the beveled slider 25 moves past the card ball 24, the card ball 24 is supported by the support spring 2 3, the supporting force of the bevel slider 25 is used to limit the movement of the bevel slider 25, so that the pin plate 26 and the pin 28 are always kept inside the power adapter 1. After the ball 24 clamps the bevel slider 25, the user can push the protection panel 37 to move in the protection plate slide groove 31, so that the protection panel 37 completely covers the groove of the power adapter 1. When it is completely covered, it is necessary to pull the pull plates 32 on both sides to make the slide plate 36 move normally. After covering, the fixed plates 35 on both sides are pushed to fit the outer wall of the protection panel 37 through the elastic support of the tension spring 34, and close to the outer side of the slide plate 36 to limit the movement of the protection panel 37 to prevent the protection panel 37 from sliding.

[0038] Secondly, after the pin plate 26 is moved to the inside of the power adapter 1 for fixation, the pin plate 26 pushes the upper pressing plate 4 to move upward. At this time, the pressing plate 4 protrudes from the surface of the power adapter 1. When the user needs to use the power adapter 1, the protection panel 37 is first opened, and then the pressing plate 4 is pressed to apply external force to make the fixing of the bevel slider 25 by the balls 24 on both sides fall off. The pin plate 26 drives the pin 28 to pop out of the power adapter 1, and then the pull plate 32 is pulled to insert the fixing plate 35 into the limit grooves 27 on both sides of the pin plate 26.
