DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0038] See also Figure 1-Figure 7 The present invention provides a technical solution: a lamp pole adjustment structure for a lighting device, comprising a lamp pole body 1, a side inner wall of the lamp pole body 1 is penetrated and fixedly installed with an inspection frame 2, an inspection door 12 is movably installed in the inspection frame 2, a threaded rod 11 is movably installed in the lamp pole body 1, a placement plate 5 is movably installed on the top of the threaded rod 11, a connecting groove block is provided at the bottom end of the placement plate 5, the top of the threaded rod 11 is movably installed in the connecting groove block, a controller 10 is connected to the placement plate 5 by bolts, a pushing mechanism 9 is provided in the lamp pole body 1, the pushing mechanism 9 can drive the threaded rod 11 to rotate and drive the placement plate 5 to move upward, and move to above the inspection door 12, so as to prevent rainwater from entering the interior of the lamp pole body 1 through the gap between the inspection door 12 and the inspection frame 2, and to prevent rainwater from corroding the controller 10 and damaging the controller 10.

[0039] A heat dissipation through hole is opened through the side wall of the lamp pole body 1, and the heat dissipation through hole is located below the maintenance frame 2. The heat dissipation through hole facilitates the heat dissipation channel generated by the controller 10 and other working parts inside the lamp pole body 1, thereby avoiding excessive temperature in the inner cavity of the lamp pole body 1 and preventing damage to the controller 10 and other working parts.

[0040] In this embodiment, the pushing mechanism 9 includes a pushing column 19 and a connecting tube 8. A tooth block portion 23 is fixedly installed on the pushing column 19. A rotating gear 15 is movably installed in the connecting tube 8. The rotating gear 15 is meshingly connected with the tooth block portion 23. When the pushing column 19 moves, it can drive the rotating gear 15 to rotate through the tooth block portion 23.

[0041] In this embodiment, the threaded rod 11 passes through the rotating gear 15, and a threaded rotating groove matching the threaded rod 11 is opened inside the rotating gear 15. The threaded rod 11 extends into the connecting tube 8 through the rotating gear 15 and the threaded rotating groove. When the rotating gear 15 rotates, it can drive the threaded rod 11 to rotate through the threaded rotating groove, and drive the threaded rod 11 to rise or fall in the connecting tube 8. When the threaded rod 11 rises, it can drive the top placement plate 5 to move upward until the bottom end surface of the placement plate 5 is higher than the top end surface of the inspection door 12, thereby preventing rainwater from entering the inner cavity of the lamp pole body 1 through the inspection door 12 and splashing onto the controller 10 on the placement plate 5, thereby preventing the street lamp from leaking electricity and damaging the street lamp.

[0042] In this embodiment, a fixed frame 7, a connecting frame 13, a fixed rod 14 and a sliding block 25 are respectively provided in the lamp pole body 1. The fixed rod 14 is located on both sides of the connecting frame 13. The side of the pushing column 19 passes through the fixed rod 14. A first extrusion spring 24 is provided in the connecting frame 13. The end of the pushing column 19 is fixedly connected to the first extrusion spring 24.

[0043] In this embodiment, a sliding groove 20 and a pushing groove 22 are respectively provided in the inspection frame 2, and the sliding groove 20 and the pushing groove 22 are connected to each other. A pushing block 21 is fixedly installed under the inspection door 12, and the pushing block 21 is located in the sliding groove 20 and contacts with the pushing column 19 located in the pushing groove 22. The shape of the pushing column 19 is Y-shaped, and the tooth block portion 23 is located on the inner side of one side of the pushing column 19. After the inspection door 12 enters the inspection frame 2, the pushing block 21 at the bottom end of the inspection door 12 will contact the end of the pushing column 19 in the sliding groove 20, and drive the pushing column 19 to move in the pushing groove 22. At the same time, when the pushing column 19 moves, it will drive the rotating gear 15 to rotate through the tooth block portion 23, and at the same time, the pushing column 19 will squeeze the first extrusion spring 24 in the connecting frame 13.

[0044] When in use, the controller 10 is installed on the placement plate 5. At this time, the placement plate 5 is flush with the bottom end surface of the inspection door 12, which makes it easy to work inside the lamp pole body 1 and install the controller 10. After the controller 10, ballast, capacitor and other components required for the street lamp are installed, the inspection door 12 is installed into the inspection frame 2. The inspection door 12 drives the push block 21 to push the push column 19 to move in the push groove 22. When the push column 19 moves, it drives the rotating gear 15 to rotate through the tooth block part 23. At the same time, it will enter the connecting frame 13 to squeeze the first extrusion spring 24. When the rotating gear 15 rotates, it will drive the lead screw 11 to extend from the connecting tube 8 through the threaded rotating groove, and drive the top placement plate 5 to move up. When the pushing column 19 cannot move, the placement plate 5 moves to above the inspection door 12, which can prevent rainwater from entering the inner cavity of the lamp pole body 1 through the gap between the inspection door 12 and the inspection frame 2, prevent rainwater from contacting the control components inside the lamp pole body 1, protect the safety of the control components, and prevent street lamp leakage.

[0045] See also Figure 1-Figure 5 , Figure 8-Figure 12 The present invention provides a technical solution: in this embodiment, a second extrusion spring 28 is fixedly installed in the fixing frame 7, and a toggle plate 16 is arranged below the second extrusion spring 28. The toggle plate 16 can open and disconnect the switch of the controller 10. When the placement plate 5 drives the controller 10 to move upward, the toggle plate 16 will contact the switch of the controller 10 and turn on the controller 10. When the placement plate 5 moves downward, the toggle plate 16 will contact the controller 10, disconnect the power supply of the controller 10, and at the same time cut off the power to the entire street lamp, so that the staff can perform power-off processing when replacing the street lamp or inspecting the internal circuit of the street lamp to ensure the safety of the staff.

[0046] In this embodiment, a push rod 18 is fixedly installed on the side of the placement plate 5, and a first sliding through hole 17 matching the push rod 18 is opened in the fixed frame 7. The push rod 18 slides in the first sliding through hole 17 and contacts the sliding block 25, driving the sliding block 25 to move laterally. A bevel groove 29 matching the push rod 18 is opened in the sliding block 25. When the placement plate 5 is rising, the push rod 18 is located in the bevel groove 29 and contacts the lowest point of the bevel groove 29. At this time, the push rod 18 will squeeze the third squeezing spring 33 of the sliding block 25 through the bevel groove 29. At the same time, the bevel push rod 30 on the sliding block 25 will contact the lower part of the bevel of the bevel block 27. The toggle plate 16 is located in the first sliding through hole 17, and the second squeezing spring 28 at the top of the toggle plate 16 is in a squeezed state.

[0047] In this embodiment, a fixing column 32 is fixedly installed on the inner wall of the lamp pole body 1, the side of the sliding block 25 passes through the fixing column 32, and a third extrusion spring 33 is arranged on the fixing column 32, and an inclined push rod 30 is fixedly installed above the sliding block 25, the inclined push rod 30 passes through the inner wall of the fixing frame 7 and extends into the interior of the fixing frame 7, and the inner wall of the fixing frame 7 is penetrated by a second sliding through hole 31 matching the inclined push rod 30.

[0048] In this embodiment, a sloped block 27 and a lifting rod 26 are provided on the toggle plate 16, and the sloped push rod 30 is in contact with the sloped block 27 through the slope. A protective plate 6 is provided under the lifting rod 26, and several protective plates 6 are located around the placement plate 5, and several protective plates 6, the placement plate 5 and the fixed frame 7 in the same plane form a closed circle inside the lamp pole body 1. The four protective plates 6 are respectively located in the four symmetrical corners of the placement plate 5, and two adjacent fixed frames 7 are located on both sides of the placement plate 5 and are symmetrically distributed. When the inspection door 12 is opened, a closed circle will be formed between the placement plate 5, the protective plate 6 and the fixed frame 7 to form a platform to prevent the controller 10 on the placement plate 5 from falling into the inside of the lamp pole body 1 during installation. At the same time, a working platform is also formed inside the lamp pole body 1 to facilitate operation by the staff.

[0049] When in use, when the placement plate 5 rises, the push rod 18 at the bottom end of the placement plate 5 is located in the inclined groove 29 of the sliding block 25. As the placement plate 5 rises, the push rod 18 and the inclined groove 29 begin to separate from each other, and the sliding block 25 begins to return to its original position under the action of the third extrusion spring 33. When the sliding block 25 moves, it will drive the inclined push rod 30 to move together, and the inclined push rod 30 will drive the inclined block 27 to move downward through the inclined surface, and at the same time drive the toggle plate 16 to move downward. At this time, the controller 10 on the placement plate 5 is in an upward state, and the toggle plate 16 is in an upward state. The plate 16 will turn on the switch of the controller 10 during the downward movement, so that the street lamp 4 is in a power-on state. At the same time, when the toggle plate 16 moves downward, the protective plate 6 will be driven downward by the lifting rod 26, and will not stop moving until the placement plate 5 moves upward. In this way, the protective plate 6 around the placement plate 5 will also be separated from the placement plate 5, forming a channel around the placement plate 5. In this way, the heat generated by the working parts such as the controller 10 located on the placement plate 5 will diffuse downward through this channel and dissipate through the heat dissipation holes to prevent the temperature in the inner cavity of the lamp pole body 1 from being too high.

[0050] See also Figure 1 The present invention provides a technical solution: In this embodiment, a lifting cylinder 3 is fixedly installed on the outer side of the lamp pole body 1, and a street lamp 4 is arranged on the output shaft end of the lifting cylinder 3. One end of the street lamp 4 is movably connected to the lamp pole body 1 through a hinge seat.

[0051] When in use, the angle of the street lamp 4 is adjusted by lifting the cylinder 3, so as to facilitate use.

[0052] Working principle of this embodiment: the controller 10 is installed on the placement plate 5. At this time, the placement plate 5 is flush with the bottom end surface of the inspection door 12, which makes it easy to operate inside the lamp pole body 1 and install the controller 10. After the controller 10, ballast, capacitor and other components required for the street lamp are installed, the inspection door 12 is installed into the inspection frame 2. The inspection door 12 drives the push block 21 to push the push column 19 to move in the push groove 22. When the push column 19 moves, it drives the rotating gear 15 to rotate through the tooth block part 23. When the gear 15 rotates, the lead screw 11 is driven to extend from the connecting tube 8 through the threaded rotating groove, and the placement plate 5 at the top is driven to move upward. When the push column 19 cannot move, the placement plate 5 moves to the top of the inspection door 12, so as to prevent rainwater from entering the inner cavity of the lamp pole body 1 through the gap between the inspection door 12 and the inspection frame 2, and prevent rainwater from contacting the control components inside the lamp pole body 1, thereby protecting the safety of the control components and preventing leakage of the street lamp.

[0053] When the placement plate 5 rises, the push rod 18 at the bottom end of the placement plate 5 is located in the inclined groove 29 of the sliding block 25. As the placement plate 5 rises, the push rod 18 and the inclined groove 29 begin to separate from each other, and the sliding block 25 begins to return to its original position under the action of the third extrusion spring 33. When the sliding block 25 moves, it will drive the inclined push rod 30 to move together, and the inclined push rod 30 will drive the inclined block 27 to move downward through the inclined surface, and at the same time drive the toggle plate 16 to move downward. At this time, the controller 10 on the placement plate 5 is in an upward state, and the toggle plate 16 is 6 will turn on the switch of the controller 10 during the downward movement, so that the street lamp 4 is in a power-on state. At the same time, when the toggle plate 16 moves downward, the lifting rod 26 will drive the protective plate 6 to move downward, and stop moving until the placement plate 5 moves upward. In this way, the protective plate 6 around the placement plate 5 will also be separated from the placement plate 5, forming a channel around the placement plate 5. In this way, the heat generated by the working parts such as the controller 10 located on the placement plate 5 will diffuse downward through this channel and dissipate through the heat dissipation holes to prevent the temperature in the inner cavity of the lamp pole body 1 from being too high.

[0054] When the inspection door 12 is moved out of the inspection frame 2, the pushing column 19 loses the thrust of the pushing block 21, and under the action of the first extrusion spring 24, the pushing column 19 will drive the threaded rod 11 to move downward through the tooth block part 23 and the rotating gear 15, and at the same time drive the placement plate 5 to move downward. During the downward movement of the placement plate 5, the pushing rod 18 at its bottom end will be inserted into the inclined groove 29 through the first sliding through hole 17, and will drive the sliding block 25 to move toward the middle of the inner cavity of the lamp pole body 1 through the inclined groove 29. At the same time, when the sliding block 25 moves, it will also drive the toggle plate 16 to move upward through the inclined push rod 30. When the toggle plate 16 moves upward, the switch of the controller 10 will be disconnected, and the street lamp 4 will be powered off. At the same time, when the toggle plate 16 moves upward, it will drive the lifting rod 26 to move upward, so that the protective plate 6 will also move up to form a platform with the placement plate 5.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
