One end of the lighting lamp socket 6 is electrically connected to a conductive sheet 7, and the conductive sheet 7 and the electric plug 4 are electrically connected to the LED lighting control board 8. It is characterized in that it further includes: A switch sealing mechanism, which penetrates through the end cap 5 and contacts the touch switch 9 to press and trigger the touch switch 9 and provide sealing; A detection and replacement mechanism, which penetrates through the end cap 5 and is located outside the switch sealing mechanism to detect moisture and prompt to replace the switch sealing mechanism; A power-off protection mechanism, which is rotatably penetrated through the electric plug 4 and is connected to the detection and replacement mechanism to cut off the power supply of the drive power supply when maintaining the detection and replacement mechanism; A maintenance structure, which penetrates through one side of the end cap 5 and the LED lamp drive housing 1, is located outside the conductive sheet 7, and is connected to the power-off protection mechanism to maintain the conductive sheet 7.

[0018] Specifically, a conductive seat 10 is electrically connected to the LED lighting control board 8. A conductive rod 11 is fixedly penetrated through the inside of the conductive seat 10, and the conductive rod 11 is electrically connected to the electric plug 4. The LED lamp drive housing 1 can provide stable support for the retaining plate 2 and the end cap 5. The retaining plate 2 can provide support for the plug 3. The plug 3 can stably support the electric plug 4. The plug 3 can play a role of positioning and guiding, so that the electric plug 4 can be inserted into the hole position for electrical connection. At the same time, the plug 3 will provide support for the LED lamp drive housing 1 under the support of the hole position for electrical connection. The staff can separate the end cap 5 from the LED lamp drive housing 1 and remove the end cap 5 to replace the switch sealing mechanism, and the end cap 5 can provide stable support for the lighting lamp socket 6.

[0019] In the actual application process of this embodiment: The lighting lamp socket 6 can provide an installation space for the LED lamp. The LED lighting electric control board 8 can stably support the touch switch 9 and the conductive seat 10 under the support of the LED lamp driving housing 1. The touch switch 9 can be pressed and triggered to control the on / off of the circuit through the LED lighting electric control board 8, so as to control the lighting and extinguishing of the LED lamp through the lighting lamp socket 6. The plug 4 can transmit the current to the LED lighting electric control board 8 through the conductive rod 11 and the conductive seat 10. After the voltage and current are regulated by the LED lighting electric control board 8, when the touch switch 9 controls the current to flow, the current will be transmitted to the conductive sheet 7 through the LED lighting electric control board 8, so that the conductive sheet 7 transmits the current to the lighting lamp socket 6, and then powers the LED lamp through the lighting lamp socket 6, thereby driving the LED lamp to light up.

[0020] When it is necessary to extinguish the LED lamp, press and trigger the touch switch 9 again to disconnect the current flow through the LED lighting electric control board 8, then the current leading to the lighting lamp socket 6 can be blocked, and the LED lamp can be extinguished.

[0021] As a preferred embodiment of the present invention, the switch sealing mechanism includes: The U-shaped ring sleeve 12 is arranged through the end cover 5; The rubber sleeve 13 is inserted inside the U-shaped ring sleeve 12; The rubber ring 14 is fixed at one end of the rubber sleeve 13; The arc-shaped rubber ring 15 is fixed inside the rubber ring 14; The pressing head 16 is fixed inside the arc-shaped rubber ring 15; The pressing pad 17 is arranged through the U-shaped ring sleeve 12, and one end is fixedly connected to the pressing head 16, and the other end extends to one end of the end cover 5.

[0022] Specifically, the conductive seat 10 is electrically connected to the LED lighting electric control board 8.

The rubber sleeve 13 can support the rubber ring 14. The rubber ring 14 can be attached to the rubber sleeve 13. The rubber ring 14 can support the arc-shaped rubber ring 15. The arc-shaped rubber ring 15 can support the pressing head 16, and the arc-shaped rubber ring 15 has an inner concave arc so as to be deformed by an external force, thus facilitating the translation of the pressing head 16 under the action of the external force. The pressing head 16 can stably support the pressing pad 17, and the pressing pad 17 can be attached to the outer surface of the end cover 5.

[0023] In the actual application process of this embodiment, the pressing pad 17, the pressing head 16, the arc rubber ring 15, the rubber ring 14, the rubber sleeve 13 and the U-ring sleeve 12 cooperate to play a sealing role, preventing moisture from entering the LED lamp driving housing 1. The staff can press the pressing pad 17 under the support of the end cover 5 as needed, so that the pressing pad 17 is concavely deformed under the action of external force, and use the external force to push the pressing head 16, so that the pressing head 16 uses the external force to push the arc rubber ring 15, so that the arc rubber ring 15 is deformed under the support of the rubber ring 14, the rubber sleeve 13 and the U-ring sleeve 12. Furthermore, the pressing head 16 can translate in the direction close to the touch switch 9 under the action of pressure, and then the pressing head 16 squeezes and triggers the touch switch 9, thus facilitating the operation of the touch switch 9 to control the on and off of the circuit.

[0024] As a preferred embodiment of the present invention, the detection and replacement mechanism includes a detection component and a replacement component. The detection component is connected to the replacement component. The replacement component is located outside the pressing pad 17. The detection component penetrates the end cover 5 and is located outside the U-ring sleeve 12 and the rubber ring 14. The detection component includes: A sleeve 20, fixedly connected through the end cover 5 and located outside the U-ring sleeve 12 and the rubber ring 14; A cotton ring 18, sleeved outside the rubber ring 14 and the U-ring sleeve 12 and located inside the sleeve 20; Cobalt chloride test paper 19, inserted at both ends of the cotton ring 18, and one end penetrates the end cover 5.

[0025] Specifically, the end cover 5 can provide stable support for the sleeve 20. The sleeve 20 can provide support for the U-ring sleeve 12, and the sleeve 20 can provide a setting space for the cotton ring 18 and can provide a protective effect for the switch sealing mechanism. The cotton ring 18 is made of sponge 59, which can provide support for the cobalt chloride test paper 19, and the cotton ring 18 can absorb and permeate moisture and transfer the moisture to the cobalt chloride test paper 19. The cobalt chloride test paper 19 can change color after detecting moisture and turn its own color into pink.

[0026] The replacement component includes: A protective cover 21, arranged at one end of the sleeve 20 and located outside the end cover 5; There are two guide grooves 22, evenly arranged on the inner wall of the sleeve 20, and one end penetrates one end of the sleeve 20; There are two guide plates 23, fixed on the inner wall of the protective cover 21 and extending into the guide grooves 22 for fitting; An observation window 25, arranged through one end of the protective cover 21 and attached to one end of the cobalt chloride test paper 19.

[0027] Specifically, the guide plate 23 is made of rubber, has elasticity, and is relatively rough. A groove 24 is formed inside the protective cover 21, and the groove 24 is located outside one end of the cobalt chloride test paper 19. The observation window 25 is located inside the groove 24. Push rods 26 are symmetrically fixed on the outside of the protective cover 21.

[0028] In the actual application process of this embodiment, the rubber sleeve 13, the rubber ring 14, and the arc rubber ring 15 will show varying degrees of aging after long-term use. Aging will affect the sealing effect, and then moisture will penetrate through the rubber sleeve 13, the rubber ring 14, and the arc rubber ring 15 into the inside of the sleeve 20. After the moisture enters the sleeve 20, it will first be absorbed by the cotton ring 18 and the cobalt chloride test paper 19 in all directions and supported by the rubber ring 14 and the U-ring sleeve 12. Subsequently, the moisture that enters the cotton ring 18 will penetrate the cotton ring 18 under the action of gravity and flow from the end of the cotton ring 18 to the cobalt chloride test paper 19, causing the cobalt chloride test paper 19 to detect the moisture, and then resulting in the discoloration of the cobalt chloride test paper 19. The staff can observe the discoloration of the cobalt chloride test paper 19 through the transparent observation window 25. When the cobalt chloride test paper 19 completely turns pink, it can remind the staff to replace the switch sealing mechanism; And the worker can, after the cobalt chloride test paper 19 discolors, push the protective cover 21 through the push rod 26 to rotate clockwise by ninety degrees as shown in Figure 1 so that the protective cover 21 transmits the external force to the guide plate 23, causing the guide plate 23 to overcome the friction with the sleeve 20 and deform, and the guide plate 23 rotates clockwise by ninety degrees along with the guide groove 22, causing the guide plate 23 to rotate to one end of the guide groove 22. At the same time, due to the existence of the groove 24, the protective cover 21 will drive the cobalt chloride test paper 19 to rotate together, and the cobalt chloride test paper 19 will drive the cotton ring 18 to rotate together under the support of the arc rubber ring 15 and the U-ring sleeve 12. Then, pull the protective cover 21 in the direction away from the LED lamp driving housing 1, causing the protective cover 21 to drive the guide plate 23 to be pulled out from one end of the guide groove 22, so that the protective cover 21 is separated from the sleeve 20, opening the opening at one end of the sleeve 20. Then, the cobalt chloride test paper 19 can be pulled out from the sleeve 20, the cotton ring 18 is dried, and a new cobalt chloride test paper 19 is replaced. Then, move the protective cover 21 to set the groove 24 outside the end of the newly replaced cobalt chloride test paper 19, and at the same time ensure that the protective cover 21 drives the guide plate 23 to insert into the inside of one end of the guide groove 22, and push the protective cover 21 to rotate counterclockwise by ninety degrees, causing the guide plate 23 to rotate counterclockwise by ninety degrees along with the guide groove 22 and cooperate with the guide groove 22 to fit with the sleeve 20 by its own elasticity, and support the protective cover 21 by the friction with the sleeve 20. At the same time, the protective cover 21 will drive the cobalt chloride test paper 19 to rotate counterclockwise through the groove 24, so that the cobalt chloride test paper 19 can push the cotton ring 18 to rotate counterclockwise and reset inside the sleeve 20.

[0032] Specifically, the plug 3 can provide a space for opening the through groove 39 and the guiding groove 40. The guiding groove 40 can provide a moving space and a guiding function for the sliding plate 41, while the through groove 39 can provide a moving space and a guiding function for the rubber block 42. The rubber block 42 is made of rubber, has elasticity, a rough surface, and can provide support for the sliding plate 41.

The support rod 37 can stably support the second magnet 38 by using the fixing component under the support of the protective cover 21. The negative pole of the second magnet 38 contacts the end cover 5. The first magnet 36 and the second magnet 38 cooperate with each other based on the principle of attraction between opposite magnetic poles. Both the first magnet 36 and the second magnet 38 are neodymium magnets and have relatively high magnetic force.

[0036] In the actual application process of this embodiment, when the staff needs to replace other components except the cobalt chloride test paper 19, the protective cover 21 can be pushed through the push rod 26 from Figure 1Rotate 45 degrees clockwise from the position shown, so that during the rotation of the protective cover 21, the second magnet 38 is driven to rotate 45 degrees clockwise together by the support rod 37.

At the same time, the connecting plate 33 will drive the connecting rod 34 to rotate together under the action of an external force, so that the connecting rod 34 pushes the U-shaped plate 31 during the rotation around the bearing 32 and moves away from the connecting plate 28 along the inner side of the U-shaped plate 31 during the rotation. Furthermore, during the clockwise rotation of the connecting rod 34 around the bearing 32, the U-shaped plate 31 can push the connecting plate 28 to rotate 45 degrees clockwise around the support rod 27 under the support of the support rod 27. At the same time, the connecting plate 28 will drive the electrode 29 to rotate counterclockwise, so that the electrode 29 is separated from the plug 4 and the conductive rod 11, thus disconnecting the circuit. At the same time, the connecting plate 28 will gradually release the resisting and supporting effect on the support plate 43 during the clockwise rotation, so that the support plate 43, the rubber block 42 and the sliding plate 41 move inward along the through groove 39 and the guiding groove 40 towards the inside of the plug 3 under the action of gravity. Furthermore, the rubber block 42 can be completely retracted into the inside of the through groove 39 and is limited and stored under the support of the guiding groove 40 and the sliding plate 41, thus releasing the frictional resistance between the rubber block 42 and the hole position of the electrical connection. After that, the driving power supply can be pulled out of the hole position of the electrical connection after power-off.

[0037] Before inserting the plug 4 and the plug 3 into the hole position of the electrical connection, the staff needs to rotate the protective cover 21 45 degrees clockwise, and after inserting the plug 4 and the plug 3 into the hole position of the electrical connection, rotate the protective cover 21 45 degrees counterclockwise to reset the protective cover 21 to as Figure 1At the position shown, during this process, the connecting rod 34 will drive the cover 21 through the connecting plate 33, the first magnet 36 and the second magnet 38, and push the connecting plate 28 to rotate counterclockwise with the strut 27 as the center through the U-shaped plate 31. Then, during the rotation of the connecting plate 28, the end of the connecting plate 28 is used to push the support plate 43, so that the support plate 43 gradually pushes the rubber block 42 and the sliding plate 41 upward as the connecting plate 28 rotates counterclockwise. Until the connecting plate 28 rotates counterclockwise by 45 degrees, the rubber block 42 extends out from the inner side of the through groove 39, and under the resistance of the thrust and the hole position of the electrical connection, the rubber block 42 is squeezed and deformed and tightly adheres to the inner wall of the hole position of the electrical connection by the elastic force, so as to provide the resistance for pulling out the plug 3 by the elastic force and its own roughness. When the staff pulls the plug 3 without power off, they will feel the resistance between the rubber block 42 and the hole position of the electrical connection, thereby reminding the staff that the drive power supply is not powered off, and prompting the staff to pull out the plug 3 and the plug head 4 from the hole position of the electrical connection after power off, so as to avoid unplugging and plugging the drive power supply under non-powered-off conditions.

[0038] As a preferred embodiment of the present invention, the maintenance mechanism includes a supply and injection component and a pushing and coating component. The supply and injection component is arranged through one side of the LED lamp drive housing 1 and the end cover 5, and the pushing and coating component is arranged in the supply and injection component.

[0040] The moving and fixed parts include: Moving groove 47, which is opened through the top end of the support cylinder 45; Arc rod 50, one end of which is fixed on the slider 48 and the other end of which passes through the moving groove 47 and the arc hole 44; The spring 51 has one end fixedly connected to the inner wall of the support cylinder 45 and the other end fixedly connected to the slider 48.

[0041] Specifically, the support cylinder 45 can provide a space for opening the moving groove 47, the moving groove 47 can provide a translation space for the arc rod 50, and the support cylinder 45 can stably support the spring 51, and the spring 51 has elasticity.

[0042] The coating pushing assembly includes: An airbag 46, fixed to the inner wall of the support cylinder 45 and located below the slider 48; A pressing plate 53, fixedly connected to the slider 48 and connected to one side of the airbag 46; A hollow cylinder 55, fixed inside the support cylinder 45 and located on one side of the pressing plate 53, and communicated with the airbag 46 through a pipeline; A piston 57, arranged in contact with the inner wall of the hollow cylinder 55; A sponge 59, connected to the piston 57 through a connecting member, located inside the support cylinder 45, and aligned with the position of the conductive sheet 7; A baffle 61, fixed on the hollow cylinder 55 to block the leakage groove 49 after the slider 48 slides out of the support cylinder 45.

[0043] Specifically, a support plate 54 is fixed to the inner wall of the support cylinder 45, and the support plate 54 is fixedly connected to the hollow cylinder 55. An air pipe 56 is connected through the airbag 46, and the other end of the air pipe 56 is connected through the hollow cylinder 55 and is located at the position of one end of the piston 57 close to the airbag 46. A guide rod 58 is fixed to the end of the piston 57 away from the airbag 46, and the guide rod 58 movably penetrates through one end of the hollow cylinder 55 away from the airbag 46. The end of the guide rod 58 away from the piston 57 is fixedly connected to the sponge 59. A through hole 60 is formed through one side of the support cylinder 45 away from the airbag 46, and the through hole 60 is located between the sponge 59 and the conductive sheet 7. The support cylinder 45 can stably support the airbag 46, and the airbag 46 is filled with air. The slider 48 can stably support the pressing plate 53. The pressing plate 53 can squeeze and contract or pull and expand the airbag 46 when the sliding plate 41 translates. The hollow cylinder 55 can provide support and movement guiding for the piston 57. The piston 57 can be in contact with the inner wall of the hollow cylinder 55 to play a sealing role, so that the piston 57 can be pushed by air pressure to translate along the hollow cylinder 55. The piston 57 can drive the sponge 59 to move together through the guide rod 58 during the movement by using an external force. The sponge 59 has adsorbability. After the conductive antioxidant drops onto the sponge 59, it will penetrate into the sponge 59, and the friction between the sponge 59 and the conductive sheet 7 will smear the penetrated conductive antioxidant on the conductive sheet 7. And the sponge 59 has elasticity and can be deformed under the action of an external force and the resistance of the conductive sheet 7, and then fits the contour of the conductive sheet 7.

[0044] In the actual application process of this embodiment, before using the driving power supply, the staff can rotate the protective cover 21 clockwise by 45 degrees from the position as shown in Figure 1 . At this time, the first magnet 36 will rotate clockwise together, and then the first magnet 36 will separate from the outside of the arc rod 50 by using the arc hole 44, so as to release the limiting effect of the first magnet 36 on the arc rod 50. Subsequently, the spring 51 in the extrusion energy storage state will use the rebound force to push the slider 48 to slide away from the LED lighting control board 8 under the support of the support cylinder 45. Then, the slider 48 will drive the arc rod 50 to move along the moving groove 47 together. At the same time, the slider 48 will drive the filling port 52 to move out of the support cylinder 45. At the same time, the bottom end of the leakage groove 49 will move to fit on the baffle 61, so that the baffle 61 blocks the bottom opening of the leakage groove 49. After that, the staff needs to inject an appropriate amount of conductive antioxidant from the filling port 52 into the inner side of the leakage groove 49, and then push the slider 48 into the support cylinder 45 to make the slider 48 compress the spring 51 to contract until the slider 48 returns to its original position. At this time, the bottom opening of the leakage groove 49 will be above the sponge 59, and the conductive antioxidant in the leakage groove 49 will drip onto the sponge 59 and penetrate. At the same time, the arc rod 50 will move back along the moving groove 47. Then, the staff needs to rotate the protective cover 21 counterclockwise by 45 degrees to reset the protective cover 21 to the position as shown in Figure 1 . During this process, the protective cover 21 drives the second magnet 38 to sleeved on the outside of the arc rod 50 by using the arc hole 44 through the first magnet 36 (as shown in Figure 14 ).

[0045] When pushing the protective cover 21 as shown in Figure 1When the plug 3 and the socket 4 are unplugged or plugged in with a 45-degree clockwise rotation as shown; or when the protective cover 21 is rotated clockwise to replace the cobalt chloride test paper 19, the first magnet 36 will rotate and separate from the arc rod 50 through the arc hole 44, thus releasing the limit on the arc rod 50 and the slider 48. Then, the slider 48 is pushed by the spring 51 to move away from the LED lighting control board 8. At this time, the slider 48 will drive the pressing plate 53 to move together. During the movement of the slider 48, the pressing plate 53 squeezes the airbag 46, so that the gas in the airbag 46 can be squeezed out into the trachea 56 and enter the inside of the hollow cylinder 55 along the trachea 56. Subsequently, the air will push the piston 57 along the inner wall of the hollow cylinder 55 towards the direction close to the LED lighting control board 8 under the action of pressure. Then, the piston 57 can push the sponge 59 through the guide rod 58 to move through the through hole 60 onto the conductive sheet 7 under the guidance of the hollow cylinder 55. When the arc block is pushed into the support cylinder 45, it will pull the airbag 46 through the pressing plate 53. The airbag 46 will suck the air in the hollow cylinder 55 through the trachea 56 under the support of the support cylinder 45 by using the generated suction force, and use the generated suction force to make the piston 57 move along the hollow cylinder 55 away from the LED lighting control board 8. Then, it will drive the sponge 59 to move through the through hole 60 into the support cylinder 45 together through the guide rod 58. Thus, during the movement of the sponge 59, the conductive antioxidant is wiped and smeared on the conductor, which is convenient for maintaining the conductive sheet 7, slowing down the oxidation speed of the conductive sheet 7, and increasing the service life of the driving power supply.

[0046] Working principle: The protective cover 21 can provide support for the U-ring sleeve 12 through the connecting component, and the connecting component is located at the upper one-third of the U-ring sleeve 12, which does not affect the extraction of the cobalt chloride test paper 19. By pressing the external pressure pad 17, the pressing head 16 is pushed to squeeze the touch switch 9 to achieve circuit control. The multi-layer elastic sealing structure composed of the rubber sleeve 13, the rubber ring 14 and the arc rubber ring 15 elastically deforms when pressed. It not only allows the pressing head 16 to displace and trigger the switch, but also isolates the external moisture penetration through the sealing layer. The switch sealing mechanism integrates the waterproof and mechanical triggering functions, and resists the environmental humidity through the elastic sealing layer to extend the life of the internal circuit.

[0047] After the external force is released, the elastic restoring force of the arc rubber ring 15 and the rubber sleeve 13 resets the pressing head 16, and the sealing structure is restored to ensure long-term sealing.

[0048] After the cobalt chloride test paper 19 absorbs the infiltrated moisture, it changes color. The cotton ring 18 made of sponge 59 evenly adsorbs the moisture and guides it to the cobalt chloride test paper 19, improving the detection sensitivity. Through moisture detection, the aging state of the switch sealing component can be visually judged through the observation window 25. Rotating the protective cover 21 drives the guide plate 23 to slide along the guide groove 22. After removing the limit, the old cobalt chloride test paper 19 is taken out. After replacing the new cobalt chloride test paper 19, it is reset in the reverse direction, realizing rapid maintenance without disassembling the overall structure. The cobalt chloride test paper 19 monitors the sealing aging in real time, and the color change warns to prompt replacement, avoiding circuit failures caused by seal failure. The modular design enables the replacement of the cobalt chloride test paper 19 without professional tools, reducing the maintenance cost.

[0049] When the protective cover 21 is rotated, the second magnet 38 on the protective cover 21 drives the first magnet 36 to rotate through magnetic attraction, driving the connecting rod 34 to push the connecting plate 28 to rotate, so that the electrode 29 is separated from the plug 4, realizing forced disconnection of the circuit. When the connecting plate 28 is reset, it pushes the rubber block 42 to extend outwards, using the frictional resistance between the rubber and the inner wall of the jack to warn the non-powered state and prevent plugging and unplugging while energized. The rotating protective cover 21 linkage power-off mechanism ensures that the power is automatically cut off before maintenance, eliminating the risk of electric shock. The resistance design of the rubber block 42 provides physical feedback, forcing users to develop the habit of power-off operation and improving safety.

[0050] Pushing the slider 48 compresses the spring 51 to store energy. After injecting the conductive antioxidant, the spring 51 is released. When the slider 48 is reset, it drives the pressure plate 53 to squeeze the airbag 46, and the gas pushes the piston 57 to drive the sponge 59 to smear the conductive sheet 7, realizing uniform coverage of the antioxidant. The rotation action of the protective cover 21 synchronously triggers the movement of the slider 48, ensuring that the conductive sheet 7 is automatically maintained after each maintenance or power-off operation. The maintenance mechanism realizes the timed coating of the antioxidant on the conductive sheet 7 through mechanical linkage, reducing the poor contact caused by oxidation, significantly extending the life of the conductive components, and reducing the failure rate.

[0051] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
