In the present embodiment, the support rod on the lamp holder mechanism 2 for installing accessories such as the lamp holder 23 or the solar panel 24 is straddled on the lamp post 11, so that the center of gravity of the lamp holder mechanism 2 can be as close to the lamp post 11 as possible or be set on the lamp post 11, so that the radial load on the lamp post 11 is as small as possible, thereby ensuring the force balance of the lamp post 11 and improving the stability of the street lamp during installation and use.

[0045] Furthermore, the support rod 21 includes a first rod 211, a second rod 212 and a connecting rod 213. The connecting rod 213 is provided with a sleeve cavity 214 for sleeved on the lamp post 11. The first rod 211 is connected to one end of the connecting rod 213, and the second rod 212 is connected to the other end of the connecting rod 213. The sleeve cavity 214 is provided to facilitate the installation of the support rod 21 on the lamp post 11, so that the center of gravity of the lamp holder mechanism 2 is as close to the lamp post 11 as possible. During installation, the lamp post 11 is first placed horizontally on the ground, and then the connecting rod 213 is sleeved in the lamp post 11, and then the first rod 211 and the second rod 212 are installed on the connecting rod 213. The first rod 211 and the second rod 212 are used to connect components such as the lamp holder 23 or the solar panel 22.

[0046] Furthermore, the support rod 21 may also be Figure 2 In the structure of the second embodiment shown, the support rod 21 is provided with a wrapping recess 22 wrapped around the outer peripheral side of the lamp post 11. The structure is simple, and the lamp holder mechanism 2 does not need to be installed on the lamp post 11 in advance, and the operation is simple.

[0047] Furthermore, the lamp pole 1 includes a suspension arm 12 disposed at the upper end of the lamp post 11, a lamp holder connecting portion 13 is disposed on the suspension arm 12 at one side of the lamp post 11, and the lifting mechanism 3 includes a lifting steel rope 31 extending from the lamp holder connecting portion 13 and connected to the lamp holder mechanism 2.

[0050] Furthermore, in order to make the lamp holder mechanism 2 have an anti-falling function on the lamp post 11, the lamp post 11 includes a thick diameter section 111 and a thin diameter section 112, the minimum outer diameter of the thick diameter section 111 is greater than the maximum outer diameter of the thin diameter section 112, and the minimum outer diameter of the thick diameter section 111 is greater than the inner diameter of the sleeve cavity 214. Specifically, the lamp post 11 can be used as follows: Figure 3 The two-section structure shown is a thin-diameter section 112 located at the top and a thick-diameter section 111 located at the bottom. If the lamp holder mechanism 2 falls, the thick-diameter section 111 can prevent the lamp holder mechanism 2 from falling to the ground. The lamp post 11 can also adopt a tapered structure from top to bottom.

[0051] Furthermore, in order to facilitate the lifting of the steel rope 31 to hoist the lamp holder mechanism 2, a universal rotating connector 4 and at least one lamp pole fixed pulley 5 are provided in the suspension arm 12, and at least one lamp pole fixed pulley 5 is spaced apart from the universal rotating connector 4, and the universal rotating connector 4 includes a connecting portion 41 connected to the suspension arm 12 and a rotating portion 42 that can rotate relative to the connecting portion 41;

[0052] The lifting steel rope 31 is used to pass through the fixed pulley 5 of the lamp pole and the lamp holder mechanism 2 in sequence and then be connected to the rotating part 42, so that the lifting steel rope 31 can drive the lamp holder mechanism 2 to rise and fall relative to the lamp pole 1. By setting a universal rotating connector 4 to be connected with the lifting steel rope 31, the torsion on the lifting steel rope 31 can be unloaded through the rotating part 42 on the universal rotating connector 4, so that the lifting steel rope 31 will not cause the lamp holder mechanism 2 to deflect when lifting the lamp holder mechanism 2, and the lifting steel rope 31 will not be knotted due to its own torque, which can help to quickly and accurately install the lamp holder mechanism 2 into the lamp pole and improve the installation efficiency.

[0053] Furthermore, in order to facilitate the connection between the lamp holder mechanism 2 and the lifting steel rope 31, the lamp holder mechanism 2 includes at least one lamp holder pulley that is wound with the lifting steel rope 31. Or the lamp holder mechanism 2 includes a first lamp holder pulley 61 and a second lamp holder pulley 62 arranged in parallel, and the lifting steel rope 31 is connected to the rotating part 42 after passing through the lamp pole fixed pulley 5, the first lamp holder pulley 61 and the second lamp holder pulley 62 in sequence.

[0054] Further, in order to facilitate the locking or unlocking of the lamp holder mechanism 2 and the lamp holder connecting portion 13, the lamp holder mechanism 2 includes a lamp holder connecting rod 25 whose shape is adapted to the lamp holder connecting portion 13 and can be inserted into the lamp holder connecting portion 13, and the locking mechanism 7 includes a one-way locking plate 71 which is arranged in the lamp holder connecting portion 13 and can rotate and crosses the lamp holder connecting portion 13 under the action of gravity, and the lamp holder connecting portion 13 is also provided with a supporting portion for supporting the one-way locking plate 71 when the one-way locking plate 71 is cross-arranged, and the one-way locking plate 71 can penetrate the lamp holder connecting portion 13 and the lamp holder connecting rod 25 to lock the lamp holder mechanism 2 on the lamp pole 1 or detach from the lamp holder connecting rod 25 to unlock the lamp holder mechanism 2 and the lamp pole 1;

[0055] The lamp holder connecting portion 13 is provided with a lamp pole locking opening 131 for the one-way locking plate 71 to pass through, and the lamp holder connecting rod 25 is provided with a lamp holder locking opening 251 for the one-way locking plate 71 to pass through. A structural opening is provided on the side of the lamp holder connecting portion 13 opposite to the lamp pole locking opening 251, and a supporting portion for supporting the one-way locking plate 71 is provided at the structural opening; an unlocking baffle 72 that can move in the up-down direction is provided on the lamp holder connecting rod 25 for sliding toward one side of the lamp pole locking opening 131, and an unlocking baffle 72 that can move in the up-down direction is provided above the lamp holder locking opening 251 for The one-way locking plate 71 is pushed away from the push plate protrusion 73 of the unlocking baffle 72. The upper edge of the unlocking baffle 72 is provided with a protruding plate 721. After the lamp holder mechanism 2 moves upward to push the one-way locking plate 71 out of the lamp holder locking opening 251, the protruding plate 721 abuts against the one-way locking plate 71, so that when the lamp holder mechanism 2 moves downward, it drives the unlocking baffle 72 to slide relative to the lamp holder connecting rod 25 to block the one-way locking plate 71 from penetrating into the lamp holder locking opening 251, until the push plate protrusion 73 pushes the one-way locking plate 71 away from the unlocking baffle 72. When the locking cam 72 is in the state of being lifted up, the locking cam 71 is in the state of being lifted up and the lock cam 73 is in the state of being lifted up, so that the lock cam 71 can be locked to the locking cam 71 by the locking cam 73.

[0056] When the lamp holder mechanism 2 is installed on the lamp pole 1, Figures 10 to 12 As shown, during the process of the lamp holder mechanism 2 being hoisted into the lamp pole 1 by the lifting steel rope 31, the lamp holder mechanism 2 will first be inserted into the lamp holder connecting part 13 through the lamp holder connecting rod 25, and then the lamp holder connecting rod 25 will push upward the one-way locking plate 71 which is horizontally arranged in the lamp holder connecting part 13 during the upward movement. After the lamp holder connecting rod 25 pushes the one-way locking plate 71, the one-way locking plate 71 will be close to the lamp holder connecting rod 25 under the action of gravity, and the lamp holder connecting rod 25 will continue to move upward until the lamp holder locking opening 251 is aligned with the one-way locking plate 71. Then, the one-way locking plate 71 will flip toward the lamp holder locking opening 251 under the action of gravity, thereby horizontally connecting the lamp holder connecting part 13 and the lamp holder connecting rod 25. At this time, the lamp holder mechanism 2 can be locked on the lamp pole 1 by the one-way locking plate 71 against the upper side of the lamp holder locking opening 251, so as to prevent the lamp holder mechanism 2 from falling.

[0057] When the lamp holder mechanism 2 and the lamp pole 1 need to be disassembled, Figures 13 to 15 As shown, the lamp holder mechanism 2 is first pulled upward by the lifting steel rope 31, and then the one-way locking plate 71 is pushed open through the lower side of the lamp holder locking opening 251 when the lamp holder mechanism 2 moves upward, so that the one-way locking plate 71 is disengaged from the lamp holder locking opening 251 and is clamped on the unlocking baffle 72 located below the lamp holder locking opening 251. At this time, the lamp holder mechanism 2 is lowered by the lifting steel rope 31, and the one-way locking plate 71 is clamped with the unlocking baffle 72, so that the unlocking baffle 72 remains stationary relative to the one-way locking plate 71, and moves upward relative to the lamp holder connecting rod 25, thereby preventing the one-way locking plate 71 from passing through the lamp holder connecting rod 25 when the lamp holder mechanism 2 moves downward. Insert it into the lamp pole locking opening 251, and then the lamp holder mechanism 2 moves down to the push plate protrusion 73 above the lamp holder locking opening 251 and touches the one-way locking plate 71, the push plate protrusion 73 pushes the one-way locking plate 71 away from the unlocking baffle 72, so that the one-way locking plate 71 can be separated from the unlocking baffle, and then the one-way locking plate 71 continues to stick to the outer side surface of the lamp holder connecting rod 25 under the action of gravity, and when the lamp holder mechanism 2 moves down to completely separate from the one-way locking plate 71, the one-way locking plate 71 returns to the position across the lamp holder connecting part 13 under the action of gravity, and now the lamp holder mechanism 2 can be completely separated from the lamp pole 1.

[0058] The working principle of this embodiment is as follows:

[0059] In the present embodiment, the support rod on the lamp holder mechanism for installing the lamp holder or accessories such as the solar panel is straddled on the lamp post, so that the center of gravity of the lamp holder mechanism can be as close to the lamp post as possible or set on the lamp post, so that the radial load on the lamp post is as small as possible, ensuring the force balance of the lamp post and improving the stability of the street lamp during installation and use.
