[0002] Street lights refer to lamps that provide lighting for roads. They generally refer to lamps within the road surface lighting range in traffic lighting. Street lights are widely used in various places where lighting is needed. For street lights set up in special sections of the road, the angle of the street lights needs to be adjusted according to usage requirements.

[0003] For example, the Chinese utility model patent with application number: 202123191850.9, entitled A multi-angle adjustable LED street lamp, discloses a multi-angle adjustable LED street lamp, including a vertical pole, a first placement groove is provided at the top of the vertical pole, a reduction motor is fixedly connected to the bottom of the inner wall of the first placement groove, the output end of the reduction motor passes through the top of the vertical pole and is fixedly connected to a top pole, the bottom of the top pole is slidably connected to the bottom of the vertical pole, a groove is provided at the top on the right side of the top pole, the front and back sides of the inner wall of the groove are movably connected to a connecting rod through a rotating shaft, the right side of the connecting rod is fixedly connected to the LED street lamp body, and the bottom of the connecting rod is fixedly connected to an incomplete gear ring.

When the current in the street lamp increases, the flow speed of electrons on the filament is accelerated, and the frequency of collision with the atoms in the filament increases, resulting in an increase in the temperature of the filament and brighter light. On the contrary, the gear knob 13 is reversely active, and the current passing through the street lamp is reduced, and the brightness of the bulb is weakened.

By operating the adjustment mechanism, one or two rotations in different directions and at different angles can be realized, which is simpler and more convenient to operate. When the lamp arm 12 deflects, the transmission assembly drives the gear knob 13 to rotate to adjust the lighting brightness of the street lamp on the lamp arm 12.

[0048] In an embodiment further provided by the present invention, the adjustment mechanism includes a hollow tube 51 rotatably connected to the inner wall of the lamp post tube 1, and a gear ring 2 52, a gear long tube ring 53 and a gear ring 3 54 are rotatably connected to the hollow tube 51; the gear ring 2 52 is meshed with the steering gear 33, and the gear ring 2 52 and the steering gear 33 are arranged on the same plane, the gear long tube ring 53 is meshed with the gear ring 1 24, the gear ring 3 54 is meshed with the inner gear ring tube 41, and the gear ring 3 54 and the inner gear ring tube 41 are arranged on the same plane, and a clamping assembly is also arranged in the hollow tube 51.

[0049] In the embodiment provided by the present invention, the clamping assembly includes a handle 1 61 and a handle 2 62 which are vertically slidably connected to the hollow tube 51, and an adjusting rod 63 is fixedly connected to the handle 1 61; a spring 64 is fixedly connected between the handle 1 61 and the handle 2 62, and a plurality of control rods 65 are fixedly connected to the handle 2 62, and the plurality of control rods 65 are distributed in a circular array with the adjusting rod 63 as the center, and two groups of clamping units are arranged on the adjusting rod 63.

[0050] Specifically, the clamping unit includes a limit plate 71 fixedly connected to the adjusting rod 63, and both sides of the limit plate 71 are slidably connected with a clamping rod 72, and each clamping rod 72 is rotatably connected to the corresponding control rod 65 through a rotating bar 73. A hole matching the clamping rod 72 is provided on the gear ring 2 52, two holes matching the clamping rod 72 are provided on the gear long tube ring 53, and a hole matching the clamping rod 72 is provided on the gear ring 3 54. When the clamping rod 72 is clamped with the holes provided on the gear ring 2 52, the gear long tube ring 53 and the gear ring 3 54, the rotation of the hollow tube 51 can drive the gear ring 2 52, the gear long tube ring 53 and the gear ring fixed thereto to rotate, while the gear ring 2 52, the gear long tube ring 53 and the gear ring not fixed by the clamping rod 72 rotate idly.

[0051] In the solution further provided by the present invention, the transmission assembly includes an arcuate rack 8 fixedly connected to the mounting base 11, the arcuate rack 8 meshing with the gear knob 13, the gear knob 13 rotates as the lamp arm 12 rotates, and the arcuate rack 8 is arranged on the trajectory of the gear knob 13 rotating with the lamp arm 12, so when the gear knob 13 rotates, it will mesh and rotate with the arcuate rack 8, thereby adjusting the current in the street lamp, thereby achieving the purpose of controlling the brightness of the street lamp.

[0052] In the solution further provided by the present invention, a positioning component is provided on the lamp arm 12, and the positioning component includes a positioning rod 91 slidably connected to the lamp arm 12, and a plurality of positioning holes 92 are provided on the arc-shaped rack 8. The positioning rod 91 is engaged with the corresponding positioning holes 92. The positioning rod 91 on the lamp arm 12 can be driven to move by setting a built-in driving source. By engaging the positioning rod 91 with the positioning hole 92 on the arc-shaped rack 8, the stability of the lamp arm 12 after rotation can be ensured.

[0053] In the solution further provided by the present invention, a second positioning component is provided in the lamp post tube 1, and the second positioning component includes a fixing ring 101 fixedly connected in the lamp post tube 1, and a plurality of second positioning rods 102 are vertically slidably connected to the fixing ring 101; a plurality of second positioning holes 103 are provided on the mounting seat 11, and the second positioning rods 102 are snap-fitted with the corresponding second positioning holes 103; the second positioning rods 102 on the fixing ring 101 can be driven to move by setting a built-in driving source, and the stability of the mounting seat 11 after rotation can be ensured by snapping the second positioning rods 102 with the second positioning holes 103 on the mounting seat 11.

[0054] Working principle: when only the rotation of the lamp arm 12 needs to be adjusted, hold the handle 1 61 and pull the handle 2 62 downward to make the handle 2 62 move downward toward the handle 1 61 and squeeze the spring 64. The handle 2 62 drives the control rod 65 downward and drives the clamping rod 72 to move into the hollow tube through the cooperation of the rotating bar 73. Then, pull the handle 1 61 and the handle 2 62 at the same time until a group of clamping rods 72 are moved to the gear ring 2 52. At this time, release the pressure on the handle 2 62 first, and then the spring 64 restores the force to drive the handle 2 62 to move upward. The handle 2 62 drives the control rod 65 upward, and cooperates with the rotating bar 73 to drive a group of clamping rods 72 to be clamped in the holes on the gear ring 2 52, while the clamping rod 72 on the other side extends out of the gear. The hollow cylinder 51 can be between the second ring 52 and the gear long tube ring 53. At this time, by rotating the hollow cylinder 51, the hollow cylinder 51 rotates and drives the second gear ring 52 to rotate through the clamping rod 72. The second gear ring 52 rotates through the cooperation of the steering gear 33 to drive the hollow inner gear ring 31 to rotate. The hollow inner gear ring 31 rotates and drives the inner gear ring cylinder 41 to rotate through the fixing rod 1 42. The inner gear ring cylinder 41 meshes with the gear ring 3 54 to rotate, and the gear ring 3 54 is not connected to the hollow cylinder 51, so the gear ring 3 54 only rotates with the inner gear ring cylinder 41 and has nothing to do with the rotation of the hollow cylinder 51. When the inner gear ring cylinder 41 rotates with the hollow inner gear ring 31, it will drive the mounting seat 11 to rotate through the fixing rod 2 43. The rotation of the mounting seat 11 can adjust the position of the lamp arm 12 on the lamp column cylinder 1.

[0055] When the lamp arm 12 needs to be adjusted to rotate and deflect, the above-mentioned operation controls the clamping rod 72 to clamp with the holes on the gear ring 2 52 and the gear long tube ring 53. At this time, the hollow tube 51 rotates to drive the fixed gear ring 2 52 and the gear long tube ring 53 to rotate synchronously. The rotation of the gear ring 2 52 drives the mounting seat 11 to drive the lamp arm 12 to rotate through the cooperation of the steering gear 33, the hollow inner gear ring 31, the fixing rod 1 42, the inner gear ring tube 41 and the fixing rod 2 43, and the gear long tube ring 53 rotates to engage the gear ring 1 24 on the screw rod 22 to rotate and move the screw rod 22 in the threaded tube 21. The screw 22 moves through the extension rod 23 to adjust the angle of the lamp arm 12. When the lamp arm 12 rotates on the mounting seat 11, the gear knob 13 arranged thereon will mesh with the arc-shaped rack 8 on the mounting seat 11, so that the brightness of the street lamp on the lamp arm 12 can be adjusted.

[0056] When the clamping rod 72 is clamped with the two holes on the gear long tube ring 53 alone, rotating the hollow tube 51 can only realize the deflection of the lamp arm 12 alone. When the clamping rod 72 is clamped with the holes on the gear long tube ring 53 and the gear ring three 54, rotating the hollow tube 51 can realize the reverse rotation of the mounting seat 11 and the deflection of the lamp arm 12. Specific usage requirements can be achieved according to the adjustment of the clamping rod 72, and each time adjustment is made, it is necessary to first unlock the connection between the mounting seat 11 and the lamp arm 12 and the lamp column tube 1.

[0057] 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.
