In this embodiment, the lifting mechanism 5 includes a lifting mechanism 51 for hoisting the lamp holder mechanism 2 and a retracting device for retracting the lifting mechanism 51, which are not shown in the figure. In the present embodiment, a power socket 41 is provided on the lamp holder mechanism 2, and a power plug 42 is provided on the one-way locking plate 31, so that when the one-way locking plate 31 passes through the lamp holder connecting portion 12 and the lamp holder mechanism 2 and supports the lamp holder mechanism 2 to lock the lamp holder mechanism 2 on the lamp pole 1, the power socket 41 and the power plug 42 can be plugged in cooperation, so that it is convenient to cooperate with the mains power wire to pass through the lamp holder connecting portion 12 of the lamp pole 11, and to power on the lamp holder mechanism 2 through the power socket 41 and the power plug 42, so as to facilitate the connection to the mains power for use.

[0041] Furthermore, in order to ensure that when the lamp holder mechanism 2 is assembled and connected with the lamp holder connecting portion 12, the power socket 41 and the power plug 42 can be accurately aligned and plugged, so as to ensure that the lamp holder mechanism 2 can be powered smoothly, the lamp holder connecting portion 12 is provided with a device for limiting the locking member 3 to be in the power-on position relative to the lamp holder connecting portion 12 when the one-way locking plate 31 crosses the lamp holder connecting portion 12, so that when the lamp holder connecting portion 12 is correspondingly connected with the lamp holder mechanism 2, the power plug 42 on the one-way locking plate 31 is aligned with the power socket 41. When the locking member 3 is in the power-on position relative to the lamp holder connecting portion 12, the power plug 42 can be aligned with the power socket 41, so as to facilitate the plugging and powering of the two.

[0042] Furthermore, the locking member 3 includes a position display plate 32 and a hinge shaft 33, wherein the hinge shaft 33 is connected between the position display plate 32 and the one-way locking plate 31 for being hinged to the lamp holder connecting portion 12, and the one-way locking plate 31 and the position display plate 32 are arranged at an angle, and the limiting portion is used to limit the positioning of the one-way locking plate 31, the position display plate 32 or the hinge shaft 33 along the width direction of the one-way locking plate 31, so that the power plug 42 on the one-way locking plate 31 can be aligned with the power socket 41. The position display plate 32 is located outside the lamp holder connecting portion 12, and since the position display plate 32 is connected to the one-way locking plate 31, the staff can learn the specific position of the one-way locking plate 31 in the lamp holder connecting portion 12 by observing the position of the position display plate 32. Specifically, the limiting portion may be a first through-hole arranged in the lamp holder connecting portion 12 and having a width dimension adapted to the width of the one-way locking plate 31 and through which the one-way locking plate 31 passes. The size limitation of the first through-hole and the one-way locking plate 31 can ensure that the power-on plug 42 is located at a position aligned with the power-on socket 41; of course, the limiting portion may also be a second through-hole arranged in the lamp holder connecting portion 12 and having a width dimension adapted to the width of the position display plate 32 and through which the position display plate 32 passes. The size limitation of the second through-hole and the position display plate 32 can limit the position of the one-way locking plate 31, thereby ensuring that the power-on plug 42 is located at a position aligned with the power-on socket 41; the limiting portion may also be a limiting hole arranged at the hinge portion between the lamp holder connecting portion 12 and the one-way locking plate 31, thereby limiting the position of the hinge shaft 33, thereby realizing the movement of the one-way locking plate 31 limited along the width direction of the one-way locking plate 31, so as to ensure that the power-on plug 42 is located at a position aligned with the power-on socket 41.

[0043] Furthermore, the lamp holder mechanism 2 is provided with a lamp holder locking opening 21 for the one-way locking plate 31 to pass through, and the lamp holder locking opening 21 includes a wide diameter section 211 and a narrow diameter section 212 located above the wide diameter section 211, and the width D of the wide diameter section 211 is greater than the width A of the one-way locking plate 31, and the width d of the narrow diameter section 212 corresponds to the width A of the one-way locking plate 31.

[0044] Furthermore, in order to facilitate the insertion of the power plug 42 into the power socket 41, the power socket 41 and / or the power plug 42 are provided with a plugging guide inclined surface 411 for guiding the power plug 42 to be inserted into the power socket 41. In this embodiment, the plugging guide inclined surface 411 is provided on the power socket 41, and specifically, the plugging guide inclined surface 411 is provided on one end of the power socket 41 close to the power plug 42.

[0045] Furthermore, in order to facilitate the connection of the wire to the power plug 42, the one-way locking plate 31 or the position display plate 32 is provided with a wire opening hole 34 for the wire to pass through. The wire connected to the mains electricity can be arranged in the lamp pole 1, and can pass through the lamp post 11, the lamp cap connection part 12 and the wire opening hole 34 to energize the power plug 42.

[0046] Furthermore, a socket assembly frame 6 is provided in the lamp holder mechanism 2, and an assembly port 61 corresponding to the lamp holder locking port 21 is provided on the socket assembly frame 6, and the power socket 41 is provided on the socket assembly frame 6 and is located on the upper side of the assembly port 61, and the opening is arranged downward, and a wiring space 7 is formed between the socket assembly frame 6 and the side wall of the lamp holder mechanism 2. In this embodiment, the socket assembly frame 6 is fixedly installed in the lamp holder mechanism 2, and after installation, the upper edge of the assembly port 61 is flush with the upper edge of the lamp holder locking port 21, so that the opening edge of the power socket 41 is flush with the upper edge of the lamp holder locking port 21, so that the power socket 41 and the power plug 42 can be accurately docked. In this embodiment, the socket assembly frame 6 is provided for installing the power socket 41, so that the power socket 41 can be installed in the lamp holder mechanism 2, and the power socket 41 and the socket assembly frame 6 can form independent components for installation, disassembly, maintenance and replacement. Electric wires can extend from the power socket 41 to energize the light-emitting lamp in the lamp holder mechanism 2. In this embodiment, a fixed pulley group 62 can also be provided on the socket assembly frame 6 to cooperate with the lifting mechanism 5 to hang the lamp holder mechanism 2. The fixed pulley group 62 is provided on the socket assembly frame 6 and is located above the assembly port 61. The lifting mechanism 5 hangs the lamp holder mechanism 2 by wrapping around the fixed pulley group 62. The structure is simple and the assembly is convenient.

[0047] Furthermore, the lamp post 11 is provided with a pre-welded plate for connecting with the lifting mechanism 5. The retracting device of the lifting mechanism 5 can be arranged at the lower part of the lamp post 11. By arranging the pre-welded plate at the lower part of the lamp post 11, it is convenient to arrange the mounting frame for the retracting device to be installed, which has a simple structure and is easy to install.

[0048] Furthermore, in order to facilitate the locking or unlocking of the lamp holder mechanism 2 and the lamp holder connecting part 12, the lamp holder mechanism 2 includes a lamp holder connecting rod 22 whose shape is adapted to the lamp holder connecting part 12 and can be inserted into the lamp holder connecting part 12. The lamp holder connecting part 12 is provided with a lamp pole locking opening 121 for the one-way locking plate 31 to pass through, and the lamp holder locking opening 21 is provided on the lamp holder connecting rod 22. A structural opening is provided on the side of the lamp holder connecting part 12 opposite to the lamp pole locking opening 121, and the structural opening can be used to support the one-way locking plate 31 arranged transversely, thereby enhancing the supporting strength of the one-way locking plate 31; an unlocking baffle 72 that can move in the up-down direction is provided on the lamp holder connecting rod 22 for sliding toward one side of the lamp pole locking opening 121, and an unlocking baffle 72 that can move in the up-down direction is provided above the lamp holder locking opening 21 for The one-way locking plate 31 pushes away 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 31 out of the lamp holder locking opening 21, the protruding plate 721 abuts against the one-way locking plate 31, 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 22 to prevent the one-way locking plate 31 from penetrating into the lamp holder locking opening 21, until the push plate protrusion 73 pushes the one-way locking plate 31 away from the unlocking baffle 72. The lock body 71 is pressed down with the help of the push plate protrusion 73, and the lock body 72 is pressed down with the help of the push plate protrusion 73. When the lock body 71 is pressed down, the lock body 71 is pressed down with the help of the push plate protrusion 73. When the lock body 71 is pressed down, the lock body 71 is pressed down with the help of the push plate protrusion 73. In order to facilitate the push plate protrusion 73 to push the one-way locking plate 31 , a notch 311 and positioning protrusions 312 located on both sides of the notch 311 are provided on the side of the one-way locking plate 31 away from the hinge portion.

[0049] When the lamp holder mechanism 2 is installed with the lamp holder connecting portion 12, Figures 9 and 10As shown, during the process of the lamp holder mechanism 2 being hoisted into the lamp holder connecting portion 12 by the lifting mechanism 5, the lamp holder connecting rod 22 will first be inserted into the lamp holder connecting portion 12, and then the lamp holder connecting rod 22 will push upward the one-way locking plate 31 which is transversely arranged in the lamp holder connecting portion 12 during the upward movement. After the lamp holder connecting rod 22 pushes the one-way locking plate 31, the one-way locking plate 31 will be tightly attached to the lamp holder connecting rod 22 under the action of gravity, and the lamp holder connecting rod 22 will continue to move upward until the lamp holder locking opening 21 is aligned with the one-way locking plate 31. Afterwards, the one-way locking plate 31 will flip toward the lamp holder locking opening 21 under the action of gravity, thereby horizontally connecting the lamp holder connecting part 12 and the lamp holder connecting rod 22. At this time, the one-way locking plate 31 can be pressed against the upper side of the lamp holder locking opening 21 and the upper side of the assembly opening 61 of the socket assembly frame 6 to lock the lamp holder mechanism 2 on the lamp holder connecting part 12 to prevent the lamp holder mechanism 2 from falling. At the same time, the power plug 42 on the one-way locking plate 31 can be plugged into the power socket 41 on the socket assembly frame 6.

[0050] When the lamp holder mechanism 2 and the lamp holder connecting portion 12 need to be disassembled, Figures 11 to 13 As shown, the lamp holder mechanism 2 is first pulled upward by the lifting mechanism 5, at which time the power socket 41 is disengaged from the power plug 42, and then the one-way locking plate 31 is pushed open by the lower side of the lamp holder locking opening 21 when the lamp holder mechanism 2 moves upward, so that the one-way locking plate 31 is disengaged from the lamp holder locking opening 21 and is clamped on the unlocking baffle 72 located below the lamp holder locking opening 21. At this time, the lamp holder mechanism 2 is lowered by the lifting mechanism 5, and the one-way locking plate 31 is clamped with the unlocking baffle 72, so that the unlocking baffle 72 remains stationary relative to the one-way locking plate 31, and moves upward relative to the lamp holder connecting rod 22, thereby achieving the goal of blocking the one-way locking when the lamp holder mechanism 2 moves downward. The plate 31 is inserted into the lamp holder locking opening 21, and then the lamp holder mechanism 2 moves down to the push plate protrusion 73 above the lamp holder locking opening 21 and touches the one-way locking plate 31, the push plate protrusion 73 pushes the one-way locking plate 31 away from the unlocking baffle 72, so that the one-way locking plate 31 can be separated from the unlocking baffle 72, and then the one-way locking plate 31 continues to be close to the outer side surface of the lamp holder connecting rod 22 under the action of gravity, and when the lamp holder mechanism 2 moves down to completely separate from the one-way locking plate 31, the one-way locking plate 31 returns to the position across the lamp holder connecting part 12 under the action of gravity, and now the lamp holder mechanism 2 can be completely separated from the lamp holder connecting part 12.

[0051] The above structure can realize automatic locking of the lamp holder mechanism 2 after the lamp holder mechanism 2 is installed into the lamp holder connecting portion 12, and when disassembly is required, the lamp holder mechanism 2 can be unlocked and lowered by simply pulling the lamp holder mechanism 2 upwards, which is easy to operate and convenient to install.

[0052] Furthermore, the lamp cap connection part 12 or the lamp cap mechanism 2 is provided with a wire avoidance hole 23 for avoiding the wire electrically connected to the power plug 42. By providing the wire avoidance hole 23, when the lamp cap connection part 12 is connected to the lamp cap mechanism 2, the wire electrically connected to the power plug 42 can be prevented from being squeezed, thereby ensuring the power-on effect of the lamp cap mechanism 2.

[0053] The working principle of this embodiment is as follows:

[0054] In the present embodiment, a power socket 41 is provided on the lamp holder mechanism 2, and a power plug 42 is provided on the one-way locking plate 31, so that when the one-way locking plate 31 passes through the lamp holder connecting portion 12 and the lamp holder mechanism 2 and supports the lamp holder mechanism 2 to lock the lamp holder mechanism 2 on the lamp pole 1, the power socket 41 and the power plug 42 can be plugged in cooperation, so that it is convenient to cooperate with the mains power wire to pass through the lamp holder connecting portion 12 of the lamp pole 11, and to power on the lamp holder mechanism 2 through the power socket 41 and the power plug 42, so as to facilitate the connection to the mains power for use.
