By inserting the two plug-in boards 42 on the lampshade assembly 4 into the two insertion holes 29 respectively, the plug-in boards 42 will push the sliding frame 26 upward when inserted, so that the sliding frame 26 slides on the fixing rod 25, and the sliding frame 26 drives the transmission components 28 while sliding, so that the locking ends of the two groups of transmission components 28 on the same side move inward at the same time and are locked in the two slots 43 on both sides of the plug-in board 42 to fix the lampshade assembly 4.

[0024] like Figure 3-Figure 6 In the embodiment, a No. 1 spring 27 is sleeved on the fixing rod 25, and the No. 1 spring 27 is located above the sliding frame 26 and in the cavity between the outer shell 21 and the inner shell 22. In the initial state, the No. 1 spring 27 will always push the sliding frame 26 downward, so that the sliding frame 26 drives the transmission component 28 in the reverse direction, so that the locking ends of the transmission component 28 are maintained on both sides of the opening of the socket 29.

[0025] like Figure 6 and Figure 7 In the figure, the transmission assembly 28 includes a rotating shaft 281, which is rotatably installed and penetrates the side of the outer shell 21. The end of the rotating shaft 281 located in the outer shell 21 is fixedly connected with a gear 282.

The second rack 284 is slidably installed on the outer wall of the inner shell 22 and is parallel to the fixed frame 24. The sliding frame 26 is used to drive the first rack 283 to move upward, and the gear 282 is driven by the first rack 283, so that the gear 282 drives the second rack 284 to translate.

[0026] like Figure 6 and Figure 7 In the embodiment, the first rack 283 and the second rack 284 are perpendicular to each other and are staggered. A latch assembly 285 is installed under the end of the second rack 284 opposite to the gear 282, and the latch assemblies 285 in the four groups of transmission assemblies 28 are symmetrically arranged inwardly and arranged on both sides of the insertion hole 29. The sliding limit of the latch assembly 285 is set on the fixed frame 24. When the second rack 284 moves, it will drive the latch assembly 285 to slide on the fixed frame 24 and slide inwardly toward the insertion hole 29 at the same time.

[0027] like Figure 1-Figure 7 In the figure, a locking assembly 3 for limiting the transmission assembly 28 is provided on the outer wall of the shell 21 and the same side where the transmission assembly 28 is provided. The locking assembly 3 includes an attached shell 31, and the attached shell 31 is fixedly connected to the outer wall of the shell 21. Two groups of limiting assemblies 32 are provided in the attached shell 31, and the two groups of limiting assemblies 32 are respectively connected to the ends of the two rotating shafts 281 in the two groups of transmission assemblies 28 located on the same side, which are located outside the shell 21. The locking assembly 3 is used to limit the rotation of the transmission assembly 28, so that when the locking assembly 3 locks the transmission assembly 28, the transmission assembly 28 can only be driven in one direction to ensure the locking effect on the lampshade assembly 4.

[0028] like Figure 1 , Figure 2 , Figure 6 and Figure 7In the embodiment, a U-shaped cover plate 5 is buckled on the outer side of the shell 21, and two holes are symmetrically opened on the attached shell 31. The limit assembly 32 includes a lifting rod 321 and a ratchet 324, and the lifting rod 321 is set in the hole opened in the attached shell 31 and is fixed under the U-shaped cover plate 5. The end of the lifting rod 321 located in the attached shell 31 is fixedly connected to a wedge 322, and the ratchet 324 is fixedly connected to the end of the rotating shaft 281 located outside the shell 21, and the wedge 322 It is stuck in the tooth groove of the ratchet 324 so that the ratchet 324 can only rotate in one direction. A No. 3 spring 323 is mounted on the lifting rod 321, and the No. 3 spring 323 is located between the wedge block 322 and the top of the attached shell 31. In the initial state, the No. 3 spring 323 will always push the wedge block 322 downward, so that the wedge block 322 is embedded in the tooth groove of the ratchet 324, thereby limiting the rotation direction of the ratchet 324, so as to limit the rotation direction of the gear 282 through the rotating shaft 281.

[0029] like Figure 7 and Figure 8 In the embodiment, the latch assembly 285 includes a fixed shell 2851, a slider 287 is fixedly connected to the lower part of the fixed shell 2851, a slide groove 286 is provided on the fixed frame 24, and the fixed shell 2851 is slidably installed on the fixed frame 24 through the slide groove 286 and the slider 287, a through groove is provided on the side of the fixed shell 2851 facing the insertion hole 29, a telescopic rod 2852 is slidably arranged in the through groove, a U-shaped frame 2853 is fixedly connected to the end of the telescopic rod 2852 located outside the fixed shell 2851, a roller 2854 is rotatably installed in the opening of the U-shaped frame 2853, and the U-shaped frame 2853 and the roller 2854 can be clamped in the clamping groove 43; a limiting plate 2855 for limiting is fixedly connected to the end of the telescopic rod 2852 located in the fixed shell 2851, and a limiting hole 2852 is provided on the side of the limiting plate 2855 and in the telescopic rod 2852. 57, a limiting rod 2858 is arranged in the limiting hole 2857, and the limiting rod 2858 is fixedly connected to the inner wall of the fixed shell 2851 on the opposite side of the plug hole 29, and a No. 2 spring 2856 is sleeved on the outer side of the limiting rod 2858, and the No. 2 spring 2856 is located in the fixed shell 2851. In the initial state, the No. 2 spring 2856 will always push the limiting plate 2855 to fit on the side wall of the fixed shell 2851, so that the telescopic rod 2852 extends out of the fixed shell 2851, and under the action of the No. 2 spring 2856, when the transmission assembly 28 is driven, the roller 2854 will roll and fit on the side of the plug board 42, and when the plug board 42 is inserted into place, the roller 2854 will be accurately embedded in the card slot 43, so as to ensure the accuracy of fixing the plug board 42 and avoid the transmission assembly 28 and the plug board 42 from colliding when the plug board 42 is inserted.

[0030] like Figure 2 and Figure 3In the embodiment, an airbag strip 210 is arranged between the sliding frame 26 and the top of the shell 21, an annular airbag sealing ring 211 is arranged on the inner wall of the shell 21, and the annular airbag sealing ring 211 is located below the fixed frame 24, and the airbag strip 210 and the annular airbag sealing ring 211 are connected through a connecting tube 212. When the sliding frame 26 moves upward, the airbag strip 210 is squeezed, and the gas in the airbag strip 210 is transported into the annular airbag sealing ring 211 through the connecting tube 212 after being squeezed, so that the annular airbag sealing ring 211 expands and fills between the lampshade assembly 4 and the shell 21, thereby ensuring the sealing effect of the lampshade assembly 4 installation and preventing dust and rainwater from invading the street lamp.

[0031] like Figure 1 , Figure 5 and Fig. 9 In the figure, the lampshade assembly 4 includes a lampshade body 41, and the two plug-in boards 42 are respectively fixed on two opposite sides of the lampshade body 41, and the inner shell 22 is provided with a lighting lamp bead 23 for lighting, and the outer wall of the outer shell 21 is fixed with a lamp pole 1 for support, and the lampshade body 41 is fixed by limiting the locking of the plug-in boards 42.

[0032] During operation, since the existing street lamp shade is mainly installed by screws to fasten the shade under the lamp housing, tools are required to assist in screwing, and in order to make the shade firmly installed, a large number of screws are used for fastening, which makes the shade installation operation cumbersome and the installation speed slow, resulting in low street lamp installation efficiency. In this scheme, the two plug-in boards 42 on the side of the shade body 41 are aligned with the two plug-in holes 29 opened in the fixed frame 24 and inserted into them. When the plug-in boards 42 are inserted into the plug-in holes 29, they will enter between the transmission components 28, and when the plug-in boards 42 are inserted, they will push the sliding frame 26 upward, and the sliding frame 26 will move upward under the pressure, and squeeze the No. 1 spring 27 to make it contract, and while the sliding frame 26 slides upward, it will drive the No. 1 rack 283 to move, so that the gear 282 is driven by the No. 1 rack 283 to rotate with the rotating shaft 281 as the axis, and the rotating shaft 281 will rotate on the side wall of the housing 21; At this time, when the rotating shaft 281 rotates, it will drive the ratchet 324 to rotate. Under the action of the No. 3 spring 323, the wedge block 322 will be embedded in the tooth groove of the ratchet 324. When the ratchet 324 rotates, the bevel of the tooth groove will push the wedge block 322 upward. After being pushed, the wedge block 322 will press the No. 3 spring 323 upward to shrink it. Under the action of the No. 3 spring 323 and the wedge block 322, the ratchet 324 can only rotate in one direction, thereby making the gear 282 mesh with the No. 1 rack 283 to lock the No. 1 rack 283 and prevent it from moving downward. After the No. 3 spring 323 shrinks, the lifting rod 321 will extend upward from the attached shell 31 to lift the U-shaped cover plate 5. When the gear 282 rotates, it drives the second rack 284 to slide on the side wall of the inner shell 22, so as to drive the latch assembly 285 under its end to slide in the slide groove 286 through the slider 287, so as to push the latch assemblies 285 on both sides of the two plug holes 29 inward at the same time, and make the latch assemblies 285 on both sides of the plug holes 29 fit on the two side edges of the plug board 42; When the latch assembly 285 is attached to the side of the plug board 42, the roller 2854 inside it will be attached to the side of the plug board 42, and as the plug board 42 is continuously pushed, the sliding frame 26 will continue to move upward, and the second rack 284 in the transmission assembly 28 will continuously push the latch assembly 285 to the side of the plug board 42. At this time, the roller 2854 will roll on the side of the plug board 42, and as the second rack 284 pushes, the fixed shell 2851 will continuously translate to the side of the plug board 42. Under the obstruction of the side of the plug board 42, the telescopic rod 2852 will retract into the fixed shell 2851, and squeeze the limit plate 2855 while retracting. The second spring 2856 contracts, and when the plug-in board 42 is inserted into place, the slot 43 on its side will enter the upper part of the fixed frame 24 and be flush with the roller 2854. At this time, under the action of the second spring 2856, the roller 2854 and the U-shaped frame 2853 will be embedded in the slot 43 to lock and fix the plug-in board 42. When the plug-in board 42 is locked and fixed, the lampshade body 41 will be fixed under the lamp housing assembly 2, and its side will be located between the outer shell 21 and the inner shell 22. Because the wedge block 322 limits the rotation of the ratchet 324, the second rack 284 cannot move, thereby achieving the effect of installing and fixing the lampshade body 41. The plug board 42 will squeeze the airbag strip 210 upwards when pushing the sliding frame 26 to move upwards. After the airbag strip 210 is squeezed, the gas inside it will enter the annular airbag sealing ring 211 through the connecting pipe 212, so that the annular airbag sealing ring 211 expands and fills between the outer wall of the lampshade body 41 and the inner wall of the shell 21, thereby sealing the lampshade body 41 and the shell 21 to achieve a sealing effect, thereby preventing rainwater and dust from entering the street lamp from the connection between the lampshade and the lamp shell to affect the use of the street lamp; When the lampshade body 41 needs to be disassembled for maintenance, the U-shaped cover plate 5 is pulled upward to drive the lifting rod 321 connected thereto to extend upward from the attached shell 31. At this time, the wedge block 322 moves out of the tooth groove of the ratchet wheel 324 when it moves upward to release the rotation limit of the ratchet wheel 324. At this time, under the action of the No. 1 spring 27, the sliding frame 26 is pushed to move downward, and when the sliding frame 26 moves downward, it drives the No. 1 rack 283 to reversely drive the gear 282, and the gear 282 drives the No. 2 rack 284 to move horizontally on the fixed frame 24 again. When the sliding frame 26 moves downward, the gas in the annular airbag seal ring 211 flows back into the airbag strip 210 through the connecting pipe 212, and then the annular airbag seal ring 211 returns to its original state. At this time, the plug-in board 42 is pushed out from between the outer shell 21 and the inner shell 22 by the push of the sliding frame 26, and the lampshade body 41 can be disassembled and removed for maintenance of the street lamp. The cooperation achieves the effect of facilitating the installation of the street lamp shade. Compared with the traditional street lamp shade, the installation operation is more convenient, which effectively improves the installation efficiency of the street lamp shade, and facilitates the disassembly of the shade, thereby improving the convenience of street lamp maintenance and repair.
