Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, and particularly relates to a POE power adapter. Background Art

[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. Generally, it consists of components such as a housing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. POE, known as Power over Ethernet, and a POE power adapter is the most commonly used device for Power over Ethernet.

[0003] A power cord is usually paired with a power adapter. It is found that the existing POE power adapter cannot wind the power cord into the interior of the power adapter when not in use, and does not have the function of protecting the power cord. In this way, the power cord is always exposed outside when the power adapter is not in use, which easily causes the power cord to be damaged and cracked, thus reducing the service life of the power cord and causing unnecessary economic losses. Therefore, improvement is needed.

[0004] Therefore, it is necessary to invent a POE power adapter. Summary of the Invention

[0029] The following will describe the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Referring to the attached Figure 1 - attached Figure 5 , a POE power adapter provided by the present invention includes:

[0031] A housing 1, and a voltage conversion component 2 is fixedly connected inside the housing 1;

[0032] A support rod 3, which is fixedly connected to the inner wall of the bottom of the housing 1. A rotating rod 4 is embedded inside the support rod 3 and on one side of the housing 1. A winding drum 5 is fixedly sleeved outside the rotating rod 4. A power cord 6 is fixedly embedded inside the rotating rod 4. The power cord 6 penetrates through the bottom of the winding drum 5 and the bottom of the housing 1;

[0033] A conductive slip ring 7, which is connected to the power supply port of the voltage transformation component 2. The power input end of the conductive slip ring 7 is fixedly embedded inside the rotating rod 4 and fixedly connected to the end of the power cord 6;

[0034] A knob 8, which is fixedly connected to one end of the rotating rod 4;

[0035] Two connection ports 9 are provided. Both connection ports 9 are fixedly embedded in the top of the housing 1. Both connection ports 9 are fixedly connected to the power output ports of the voltage transformation component 2;

[0036] The power cord 6 is fixedly connected to the winding drum 5. A rubber ring 10 is fixedly connected and embedded at the bottom of the housing 1. The rubber ring 10 is sleeved outside the power cord 6 and is slidably connected to it;

[0037] In this implementation scheme, by rotating the knob 8, the rotating rod 4 can be rotated, so that the winding drum 5 can be rotated, and thus the power cord 6 can be wound around the winding drum 5. In this way, when not in use, the power cord 6 can be wound and stored inside the power adapter housing 1. In this way, the device has the function of protecting the power cord 6. The voltage transformation component 2 includes an inductor, a capacitor, a control IC, a PCB board, a transformer, etc.;

[0038] Among them, in order to achieve the purpose of preventing the rotating rod 4 from rotating randomly, the present device is implemented by the following technical solution: One side of the outer shell 1 is fixedly connected with a housing 11. One side of the housing 11 is open. The rotating rod 4 passes through the other side of the housing 11. A plurality of convex strips 12 evenly distributed in a circular shape are fixedly connected to the outside of the rotating rod 4. Two moving blocks 13 are arranged inside the housing 11. The two moving blocks 13 are respectively located at the top and bottom of the rotating rod 4. Through grooves one are opened inside the two moving blocks 13. Fixing rods 14 are slidably arranged inside the two through grooves one. The outer ends of the two fixing rods 14 are respectively fixedly connected to the inner wall of the top and the inner wall of the bottom of the housing 11. Rubber pads 15 are fixedly connected to the inner ends of the two moving blocks 13. The two rubber pads 15 are both in contact with the convex strips 12 on the outside of the rotating rod 4. Through grooves two are opened inside the two rubber pads 15. Springs 16 are fixedly connected to the outer ends of the two moving blocks 13. The outer ends of the two springs 16 are respectively fixedly connected to the inner wall of the top and the inner wall of the bottom of the housing 11. The two springs 16 are respectively sleeved on the outside of the two fixing rods 14. Push blocks 17 are slidably embedded on the front and rear sides of the housing 11. Baffles one 18 are fixedly connected to the inner sides of the two push blocks 17. The two baffles one 18 are respectively in contact with the inner walls of the front and rear sides of the housing 11. Two push rods 19 connected to the two baffles one 18 through movable hinge seats are arranged inside the two baffles one 18. The two push rods 19 located at the top of the rotating rod 4 are both connected to one of the moving blocks 13 through a movable hinge seat. The two push rods 19 located at the bottom of the rotating rod 4 are both connected to the other moving block 13 through a movable hinge seat. Baffles two 20 are fixedly connected to the outer ends of the two push blocks 17. The design of components such as the moving blocks 13, the springs 16, and the rubber pads 15 can restrict the rotating rod 4 to prevent the rotating rod 4 from rotating randomly and can prevent the power cord 6 from becoming loose;

[0039] Among them, in order to achieve the purpose of reducing wear, the present device is implemented by the following technical solution: The rotating rod 4 is connected to the outer shell 1, the support rod 3, and the housing 11 through bearings. Connecting through bearings can reduce wear.

[0040] The usage process of the present utility model is as follows: After the power adapter is used up, the two push plates two at the front and back can be pushed, so that the two push blocks 17 and the two push plates one move towards the middle. Since the push rod 19 is movably connected to the push plate one and the moving block 13 through a movable hinge seat, when the two push plates two are pushed, the two moving blocks 13 can move outward under the action of the four push rods 19, so that the two rubber pads 15 are not in contact with the ridges 12 on the rotating rod 4, thus releasing the restriction on the rotating rod 4. At the same time, the spring 16 is compressed. Subsequently, turning the knob 8 can make the rotating rod 4 rotate, and the rotation of the rotating rod 4 drives the winding drum 5 to rotate, so that the power cord 6 can be wound around the winding drum 5. In this way, when not in use, the power cord 6 can be wound and stored inside the power adapter housing 1, so that the device has the function of protecting the power cord 6. In this way, when the power adapter is not in use, the power cord 6 will not be exposed outside all the time, so that the power cord 6 is damaged and cracked, and thus the service life of the power cord 6 is increased;

[0041] After the winding is completed, slowly release the push plate two, and then under the action of the spring 16 rebounding, the two rubber pads 15 can restrict the rotating rod 4 again to prevent the rotating rod 4 from rotating randomly and avoid the power cord 6 from becoming loose.

[0042] The above is only a preferred embodiment of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
