Technical Field

[0001] The invention relates to the technical field of PoE extenders, and in particular to a waterproof PoE extender for outdoor wall mounting. Background Art

[0002] A waterproof PoE extender is a network device designed for outdoor or humid environments. It is used to extend Ethernet signals and power remote devices via PoE (Power over Ethernet). It is usually waterproof and dustproof, and is suitable for use in harsh environments. The waterproof PoE extender is equipped with multiple waterproof connectors to protect the power and data connections from short circuits or corrosion caused by moisture or dust. In the PoE system, the waterproof connectors ensure the stability of power and data transmission and avoid signal interruptions caused by environmental interference. Therefore, the waterproof connectors are usually threaded or snap-on, which are easy to install and can be firmly fixed to prevent loosening. However, there are usually the following problems:

[0003] First of all, most of the waterproof PoE extenders are installed outdoors, so the threaded or snap-on waterproof connectors need to adopt waterproof structures. However, over time, especially in outdoor environments, this part of the waterproof structure, such as the rubber ring, will loosen and lose its function of adhering to water, that is, the rubber ring can no longer resist the waterproof connector, so it is necessary to check this part of the waterproof structure in a timely manner;

[0004] Secondly, waterproof PoE extenders are all wall-mounted. This wall-mounted installation method is more susceptible to water seepage outdoors, especially rainwater that seeps into the connection between the waterproof connector and the waterproof PoE extender. Therefore, this part of the remaining water needs to be discharged in time.

[0005] To this end, we designed a waterproof PoE extender for outdoor wall mounting. Summary of the invention

[0036] Embodiment 1

[0037] Reference Figure 1-Figure 9A waterproof PoE extender for outdoor wall mounting includes a waterproof PoE extender body 1. Waterproof connectors 2 are arranged on both sides of the waterproof PoE extender body 1. The waterproof connectors 2 are connected to the waterproof PoE extender body 1 through a jack 5. In the PoE system, the waterproof connectors ensure the stability of power supply and data transmission. The waterproof PoE extender body 1 and the waterproof connectors 2 are prior art and will not be elaborated on herein.

[0038] Reference Figure 2 In this state, a ring-shaped waterproof rubber belt 7 is provided on the socket 5, wherein the waterproof rubber belt 7 slightly protrudes from the inner wall of the socket 5. This arrangement ensures that when the waterproof connector 2 is inserted into the waterproof PoE extender body 1, the waterproof rubber belt 7 abuts against the outer wall of the waterproof connector 2, thereby achieving the waterproof effect of the waterproof rubber belt 7 on the waterproof connector 2 in the socket 5.

[0039] Reference Figure 5-Figure 6 In the state, the inner wall of the jack 5 is provided with a side wall cavity 11, the water-proof rubber belt 7 is arranged in the side wall cavity 11, and the side wall cavity 11 is provided with an elastic toggle plate 13 for intercepting the water-proof rubber belt 7. It should be noted that after the water-proof rubber belt 7 is rolled up and wrapped with the expanded polystyrene, the elastic toggle plate 13 is opened, and then the water-proof rubber belt 7 is arranged according to Figure 3 When the waterproof rubber belt 7 is placed in the state, the elastic toggle plate 13 will press against the waterproof rubber belt 7 in the side wall cavity 11 to complete the preliminary fixing and limiting of the waterproof rubber belt 7.

[0040] During use, the gap originally formed due to the loose sealing of the waterproof connector 2 and the waterproof rubber belt 7 will allow rainwater to seep through the gap and reach the waterproof PoE extender body 1 after raining, and then this part of rainwater will reach the water storage ring 8.

[0041] A water storage ring 8 is arranged coaxially with the jack 5 in the waterproof PoE extender body 1, and a plurality of first water inlet holes 16 are arranged on the water storage ring 8. A water-absorbing sponge 15 is arranged in the water storage ring 8. Rainwater passing through the waterproof connector 2 and the waterproof rubber belt 7 will gather at the water storage ring 8 and enter from the first water inlet holes 16. The setting of the water-absorbing sponge 15 can effectively prevent rainwater from passing over the water storage ring 8, thereby allowing the rainwater to remain in the water storage ring 8.

[0042] A water absorption line 14 is also provided in the socket 5 for guiding rainwater that penetrates into the waterproof PoE extender body 1 into the waterproof rubber belt 7. One end of the water absorption line 14 is inserted into the water absorption sponge 15, and the other end is inserted into the waterproof rubber belt 7. Therefore, after the water absorption sponge 15 absorbs the rainwater, the rainwater therein will be guided into the temporary storage cavity through the water absorption line 14. Therefore, when the rainwater passes over the waterproof connector 2 and the waterproof rubber belt 7, the rainwater will be guided into the waterproof rubber belt 7 through the water absorption line 14.

[0043] Reference Figure 3-Figure 4 As shown, the two sides of the water-proof rubber belt 7 are rolled up and connected to form a temporary storage cavity, wherein the water-proof rubber belt 7 is coated with expanded polystyrene, wherein the expanded polystyrene is filled in the temporary storage cavity. It should be noted that the two sides of the water-proof rubber belt 7 are rolled up and connected. Compared with the traditional sealing setting, the water-proof rubber belt 7 absorbs water and expands and squeezes the waterproof connector 2 to block water. This setting method not only avoids the temporary storage cavity from bursting the water-proof rubber belt 7 due to the expansion of the expanded polystyrene due to water absorption, but also does not hinder the expansion of the expanded polystyrene due to water absorption, and pushes the water-proof rubber belt 7 to protrude further from the side wall cavity 11;

[0044] Therefore, when water seepage occurs, the expanded polystyrene in the water-proof rubber belt 7 will absorb the seeped rainwater and expand, driving the water-proof rubber belt 7 to protrude from the side wall cavity 11, and allowing the water-proof rubber belt 7 to press against the waterproof connector 2 again, so that the original gap is filled by the expansion of the water-proof rubber belt 7, and the generated gap is squeezed, thereby achieving the water-proof effect again, which can play an emergency sealing role in rainy weather for subsequent replacement.

[0045] The working principle of the present invention is as follows:

[0046] First, the waterproof connector 2 is inserted into the waterproof PoE extender body 1 through the jack 5 and fixed, wherein the waterproof rubber tape 7 wrapped with expanded polystyrene and placed in the side wall cavity 11 is used to seal the jack 5, wherein the waterproof rubber tape 7 is against the outer wall of the waterproof connector 2.

[0047] During use, the gap originally formed due to the loose sealing of the waterproof connector 2 and the waterproof rubber belt 7 will allow rainwater to seep through the gap and reach the waterproof PoE extender body 1 after raining, and then this part of rainwater will reach the water storage ring 8.

[0048] Rainwater passing through the waterproof connector 2 and the water-proof rubber belt 7 will gather at the water storage ring 8 and enter from the first water inlet hole 16. The rainwater will be guided into the temporary storage cavity through the water absorption line 14. Therefore, when the rainwater passes over the waterproof connector 2 and the water-proof rubber belt 7, the rainwater will be guided into the water-proof rubber belt 7 through the water absorption line 14.

[0049] The expanded polystyrene in the temporary storage cavity expands due to water absorption and breaks the water-proof rubber belt 7 , while it does not hinder the expanded polystyrene from expanding due to water absorption and pushes the water-proof rubber belt 7 to further protrude from the side wall cavity 11 .

[0050] When the water-proof rubber belt 7 protrudes out of the side wall cavity 11 and is pressed against the waterproof connector 2 again, the original gap is filled by the expansion of the water-proof rubber belt 7, and the generated gap is squeezed, thereby achieving the water-proof effect again, which can play an emergency sealing role in rainy weather for subsequent replacement.

[0051] Embodiment 2

[0052] It should be noted that, refer to Figure 2 In this state, the thread groove 4 is located behind the thread groove 3. Therefore, when the waterproof connector 2 is inserted into the socket 5, the thread groove 3 first passes over the socket 5, and then the thread groove 4 passes over the socket 5. Therefore, when a threaded connection is adopted, the thread groove 3 is installed in the socket 5, and when a snap connection is adopted, the thread groove 4 is installed in the socket 5.

[0053] Reference Figure 2 State, a plurality of threaded blocks 6 are provided on the inner wall of the jack 5, and the plurality of threaded blocks 6 are arranged in a circle, a first active cavity 17 is provided on the inner wall of the waterproof PoE extender body 1, and a threaded rod 9 is threadedly rotated on the first active cavity 17, a first piston 10 movable in the first active cavity 17 is provided at the end of the threaded rod 9, the threaded blocks 6 are extended and retracted on the inner wall of the jack 5 through the threaded cavity 20, wherein the first active cavity 17 is filled with oil, so that after the threaded rod 9 is rotated, the first piston 10 at the end of the threaded rod 9 will be pushed to extend and retract in the first active cavity 17, thereby promoting the pushing flow of the oil in the first active cavity 17.

[0054] The threaded chamber 20 is connected to the first active chamber 17 through the first connecting chamber 18, and multiple first connecting chambers 18 are connected through the second connecting chamber 19, wherein the first connecting chamber 18, the second connecting chamber 19 and the threaded chamber 20 are all filled with oil, so the pushing flow of the oil in the first active chamber 17 will flow into the threaded chamber 20 and push the threaded block 6 out of the threaded chamber 20, so the threaded block 6 is driven to extend and retract in the socket 5 by rotating the threaded rod 9 to push the oil.

[0055] The waterproof connector 2 is threadedly connected to the waterproof PoE extender body 1. A thread groove 3 is provided on the waterproof connector 2. The thread groove 3 has the same pitch as the thread block 6. Therefore, the waterproof connector 2 is inserted into the socket 5 in a threaded connection manner:

[0056] During the insertion process, it is necessary to first rotate the threaded rod 9 to drive the threaded block 6 in the jack 5 to extend, and then rotate the waterproof connector 2 to allow the threaded groove 3 to fit with the threaded block 6, so that the waterproof connector 2 can be screwed into the waterproof PoE extender body 1.

[0057] Embodiment 3

[0058] The waterproof connector 2 is connected to the waterproof PoE extender body 1 by a buckle. The waterproof connector 2 is provided with a plurality of threaded slots 4, which are arranged in a circle. The threaded slots 4 are adapted to the thread block 6. The waterproof connector 2 is inserted into the jack 5 by a buckle connection method:

[0059] First, insert the waterproof connector 2 into the socket 5, and then rotate the threaded rod 9. If the threaded slot 4 is not set relative to the threaded block 6 at this time, the threaded rod 9 cannot be rotated. At this time, it is necessary to rotate the waterproof connector 2, and then continue to rotate the threaded rod 9. When the threaded slot 4 on the waterproof connector 2 is rotated to the relative position of the threaded block 6, the threaded rod 9 will rotate, and then the threaded block 6 will extend and press against the threaded slot 4, thereby completing the buckle limit of the threaded block 6 and the threaded slot 4.

[0060] Embodiment 4

[0061] Reference Figure 5-Figure 9 In this state, the waterproof PoE extender body 1 is also provided with a negative pressure water absorption mechanism for absorbing and storing the infiltrated rainwater. The negative pressure water absorption mechanism is used to absorb the rainwater that penetrates through the gaps and reaches the waterproof PoE extender body 1, thereby avoiding the inflow of rainwater into the waterproof PoE extender body 1 and preventing the continuous inflow of rainwater.

[0062] The negative pressure water absorption mechanism includes a water storage chamber 24 and a second movable chamber 25. The water storage chamber 24 and the second movable chamber 25 are both opened on the inner wall of the waterproof PoE extender body 1. The water storage chamber 24 is connected with the water storage ring 8 through the second water inlet hole 23. The water storage chamber 24 is connected with the second movable chamber 25 through the lifting hole. It should be noted that when the rainwater absorbed in the water storage ring 8 flows into the water storage chamber 24 along the second water inlet hole 23, the preliminary collection of rainwater is completed.

[0063] The negative pressure water absorption mechanism also includes a lifting rod 28, which is lifted and lowered in the lifting hole. A floating plate 31 is provided on the top of the lifting rod 28. A first water hole 29 is coaxially opened on the lifting rod 28, and a plurality of second water holes 30 connected with the first water holes 29 are opened on the side wall of the lifting rod 28. Therefore, when there is no water in the water storage chamber 24, the lifting rod 28 descends under the action of gravity, wherein the second water holes 30 on the side wall of the lifting rod 28 are blocked by the lifting hole, thereby blocking the connection between the water storage chamber 24 and the second active chamber 25;

[0064] When water begins to accumulate in the water storage chamber 24, due to the float plate 31 on the top of the lifting rod 28, the liquid level in the water storage chamber 24 rises, and the buoyancy of the float plate 31 becomes increasingly greater, so that the float plate 31 will be lifted together with the lifting rod 28, and the second water hole 30 that was originally blocked by the lifting hole will be exposed to the outside. Since the first water hole 29 is connected to the second water hole 30, the rainwater in the water storage chamber 24 will pass through the second water hole 30 and the first water hole 29 and reach the second active chamber 25, thereby completing the transfer of rainwater to the second active chamber 25.

[0065] The negative pressure water absorption mechanism also includes a lifting plate 26, which is lifted and lowered in the second active chamber 25. The lifting plate 26 is reset and slid by the first reset spring 27. Therefore, the descent of the lifting plate 26 will form a negative pressure in the second active chamber 25 above the lifting plate 26, which is convenient for the transfer of rainwater in the water storage chamber 24.

[0066] The negative pressure water absorption mechanism also includes a third active chamber 32, in which a second piston 33 and a third piston 34 slide, and a second return spring 35 is connected between the second piston 33 and the third piston 34, and a pressing rod 36 is provided at the bottom of the third piston 34 to abut against the lifting plate 26, and the negative pressure water absorption mechanism also includes a push plate 12, which abuts against the water-proof rubber belt 7, and a piston rod 37 is provided on the push plate 12. The waterproof PoE extender body 1 is also provided with a third connecting chamber 21 and a fourth connecting chamber 22 that are interconnected, and the fourth connecting chamber 22 is connected to the third active chamber 32. The piston rod 37 moves in the third connecting chamber 21, so after the expanded polystyrene in the temporary storage chamber absorbs water and expands, it can not only drive the water-proof rubber belt 7 to squeeze the outer wall of the waterproof connector 2 to close the generated gap to avoid water, but also push the push plate 12 and move the piston rod 37;

[0067] The third connecting chamber 21, the fourth connecting chamber 22 and the third active chamber 32 are filled with oil. Therefore, as the push plate 12 moves with the piston rod 37, the oil is squeezed to push the second piston 33 downward, thereby squeezing the third piston 34 with the second return spring 35, and then squeezing the lifting plate 26 downward through the pressing rod 36, thereby forming a negative pressure in the second active chamber 25 above the lifting plate 26.

[0068] It should be noted that the pressing rod 36 presses down on the lifting plate 26, and the negative pressure formed is a constant value. The lifting rod 28 is affected by the buoyancy. As the amount of rainwater in the water storage chamber 24 increases, the buoyancy will become greater and greater. When the buoyancy is greater than the negative pressure suction and gravity exerted on the lifting rod 28, the lifting rod 28 is lifted. Therefore, the rainwater in the water storage chamber 24 will pass through the second water hole 30 and the first water hole 29 and reach the second active chamber 25. Therefore, the rainwater is transferred to the second active chamber 25, and then the rainwater in the second active chamber 25 is guided out through the external guiding device to complete the drainage operation. The external guiding device uses a micro water suction pump and a water pipe to guide the rainwater in the second active chamber 25. The external guiding device is a prior art and will not be elaborated on here.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
