Description

Technical Field

[0001] The utility model relates to the field of POE power supply, and more specifically, to a novel POE power supply. Background Art

[0002] POE power supply means that without making any changes to the existing Ethernet Cat.5 cabling infrastructure, it can provide DC power to some IP-based terminals such as IP phones, wireless LAN access points AP, network cameras, etc. while transmitting data signals for such devices.

[0003] When using existing POE power supplies, one type of POE power supply has no fixed structure for fixed installation, and the other type of POE power supply is fixed and installed with bolts or screws. The POE power supply without a fixed structure is often randomly placed around the device. When someone touches the POE power supply or power cord, the randomly placed POE power supply is easy to move and fall or collide with surrounding objects, thereby causing damage to the POE power supply. The POE power supply fixed and installed with bolts or screws avoids the POE power supply from moving and falling or colliding, but the user needs to screw multiple screws to fix the POE power supply. When the POE power supply needs to be moved, multiple screws also need to be screwed to remove the POE power supply, making it very cumbersome to disassemble and install the POE power supply.

[0021] The present utility model is implemented as follows Figures 1 to 5As shown in, a new type of POE power supply includes a base 1, which is a rectangular parallelepiped structure. A first cavity 10 is provided at the center of the base 1. The first cavity 10 is a rectangular parallelepiped structure. The top of the base 1 is provided with a base groove 11 located directly above the first cavity 10. A POE power supply body 2 is provided in the base groove 11. A rotating shaft 3 is rotatably provided in the first cavity 10. A blind hole for installing the rotating shaft 3 is provided in the middle position of the inner bottom surface of the first cavity 10. The rotating shaft 3 is rotatably connected in the blind hole. Preferably, a bearing is provided between the rotating shaft 3 and the blind hole. The outer ring of the bearing is fixedly connected in the blind hole, and the inner ring of the bearing is sleeved on the rotating shaft 3. The bearing allows the rotating shaft 3 to rotate more smoothly. The top of 3 passes through the bottom of the base groove 11 and is inserted into the POE power supply body 2. A horizontal cross bar 30 is provided on the side wall of the rotating shaft 3 at one end away from the first cavity 10, that is, the cross bar 30 is provided on the side wall of the rotating shaft 3 at a position adjacent to the top. The POE power supply body 2 is provided with an insertion hole 20 for inserting the rotating shaft 3 and the cross bar 30. The insertion hole 20 is provided at one end away from the first cavity 10 with a rotating cavity 23 for rotating the cross bar 30. The rotating cavity 23 is a cylindrical structure. The rotating shaft 3 is provided with a gear 4 located in the first cavity 10. The first cavity 10 is provided with a rack 5 meshing with the gear 4. The rack 5 is located on the right side of the gear 4. The front end of the rack 5 is provided with a pull rod 6 passing through the base 1.

[0022] After the base is fixed, the shaft 3 and the cross bar 30 are aligned with the insertion hole 20, and the POE power supply body 2 is placed in the base groove 11. At this time, the shaft 3 and the cross bar 30 are matched and inserted into the insertion hole 20. Then, the shaft 3 is rotated by pushing the pull rod 6 so that the cross bar 30 is rotated into the rotation cavity 23, and the cross bar 30 restricts the POE power supply body 2 from being pulled out of the base groove 11. The base groove 11 restricts the horizontal movement of the POE power supply body 2, thus completing the fixed installation of the POE power supply body 2, preventing the POE power supply body 2 from moving, falling or colliding and causing damage. When the POE power supply body 2 needs to be removed, the pull rod 6 is used to pull the rack 5, so that the cross bar 30 on the shaft 3 is rotated to a position where it can slide out of the insertion hole 20, and the POE power supply body 2 can be taken out of the base 1, thus completing the disassembly of the POE power supply body 2. When the POE power supply body 2 needs to be moved or the POE power supply body 2 needs to be repaired, the POE power supply body 2 can be quickly disassembled and assembled, which is very convenient.

[0023] Further improvements, such as Figure 2 As shown in the figure, a guide column 50 is provided at the end of the rack 5 away from the pull rod 6, that is, the guide column 50 is provided at the rear end of the rack 5, and the base 1 is provided with a guide hole 13 on the side wall of the first cavity 10. The guide column 50 is matched and inserted into the guide hole 13. The movement of the rack 5 is guided by the guide column 50 and the guide hole 13 to prevent the rack 5 and the gear 4 from being disengaged.

[0024] Further improvements, such as Figure 2 As shown in , a second cavity 12 is provided in the base 1 at a position opposite to the axis of the rack 5, and the second cavity 12 is located in front of the rack 5. The pull rod 6 passes through the second cavity 12, and a pull rod plate 60 is fixedly sleeved on the pull rod 6. The pull rod plate 60 is located in the second cavity 12 where the pull rod 6 is close to the rack 5, that is, the pull rod plate 60 is located in the second cavity 12 near the rear side. A reset spring 7 is provided between the end of the pull rod plate 60 away from the rack 5 and the side wall of the second cavity 12, and the reset spring 7 is sleeved on the pull rod 6. After the pull rod 6 is released, the pull rod 6 is reset under the action of the pull rod plate 60 and the reset spring 7. At this time, the pull rod 6 drives the rotating shaft 3 to reset through the rack 5 and the gear 4. At this time, the cross bar 30 on the rotating shaft 3 is located in the rotating cavity 23, thereby limiting the POE power supply body 2 from being pulled out of the base slot 11.

[0025] Further improvements, such as Figures 3 to 5 As shown in the figure, there are two cross bars 30, and the two cross bars 30 are correspondingly arranged on the opposite sides of the shaft 3. The shaft 3 is a cylindrical structure. The insertion hole 20 includes a shaft hole portion 21 and two cross bar hole portions 22. The two cross bar hole portions 22 are correspondingly located on the opposite sides of the shaft hole portion 21.
