[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0044] See also Figure 1-9 As shown, a street lamp shade quick installation structure, such as Figure 3-Figure 5 The lamp housing assembly 2 includes an outer shell 21, an inner shell 22 is fixedly connected to the outer shell 21, a fixed frame 24 is fixedly connected to the cavity between the outer shell 21 and the inner shell 22, a plurality of fixed rods 25 are evenly distributed and fixed on the fixed frame 24, a sliding frame 26 is slidably provided on the fixed rods 25, two symmetrical holes 29 are provided on the fixed frame 24, and the sliding frame 26 is limited by the plurality of fixed rods 25 to ensure the overall movement stability of the sliding frame 26.

[0045] like Figure 4 and Figure 9 In the embodiment, a lampshade assembly 4 is provided under the lamp housing assembly 2, and two plug-in boards 42 are provided in the lampshade assembly 4. The two plug-in boards 42 have slots 43 on their sides, and the two plug-in boards 42 can be respectively inserted into the two sockets 29; Figure 3-Figure 6In the embodiment, two groups of transmission components 28 are symmetrically arranged on the opposite sides of the shell 21, and four groups of transmission components 28 are symmetrically arranged on both sides of the socket 29. One of the transmission ends of the transmission components 28 is connected to the bottom of the sliding frame 26, and the locking ends of the four groups of transmission components 28 are symmetrically arranged inwardly and can be locked in the slots 43 on both sides of the plug-in board 42 to fix the lampshade assembly 4 under the lamp housing assembly 2. By inserting the two plug-in boards 42 on the lampshade assembly 4 into the two sockets 29 respectively, the plug-in board 42 will push the sliding frame 26 upward when it is inserted, so that the sliding frame 26 slides on the fixing rod 25, and the sliding frame 26 drives the transmission component 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.

[0046] 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 fixedly connected to the outer wall of the shell 21, and two groups of limiting assemblies 32 are provided in the attached shell 31. 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.

[0047] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 In the embodiment, two holes are symmetrically opened on the attached shell 31, and the limiting assembly 32 includes a lifting rod 321 and a ratchet 324, and the lifting rod 321 is set through the hole opened in the attached shell 31, and the limiting assembly 32 is used to limit the rotation direction of the gear 282.

[0048] 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 assembly 28 in the reverse direction, so that the locking ends of the transmission assembly 28 are maintained on both sides of the opening of the socket 29.

[0049] like Figure 6 and Figure 7In the figure, the transmission assembly 28 includes a rotating shaft 281, which is rotatably installed and passes through the side of the outer shell 21. The end of the rotating shaft 281 located in the outer shell 21 is fixedly connected to a gear 282. The gear 282 is simultaneously engaged with a second rack 284 and a first rack 283 for transmission, and the first rack 283 is vertically fixed below the sliding frame 26. 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 move horizontally.

[0050] like Figure 6 and Figure 7 In the figure, the No. 1 rack 283 and the No. 2 rack 284 are perpendicular to each other and are staggered. A latch assembly 285 is installed under the end of the No. 2 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 on both sides of the socket 29. The sliding limit of the latch assembly 285 is set on the fixed frame 24. When the No. 2 rack 284 moves, it will drive the latch assembly 285 to slide on the fixed frame 24 and slide inward toward the socket 29 at the same time.

[0051] like Figure 6 and Figure 7 In the embodiment, the two sets of limit assemblies 32 are respectively connected to the ends of the two rotating shafts 281 in the two sets of transmission assemblies 28 on the same side, which are located outside the housing 21, to ensure that the transmission assemblies 28 can only be driven in one direction, thereby ensuring the normal operation of the device.

[0052] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 In the embodiment, the lifting rod 321 is fixedly connected under the U-shaped cover 5, and the end of the lifting rod 321 located in the attached shell 31 is fixedly connected with a wedge 322, and the ratchet 324 is fixedly connected to the end of the rotating shaft 281 located outside the outer shell 21, and the wedge 322 is clamped 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 provided on the lifting rod 321, and the No. 3 spring 323 is located between the wedge 322 and the top of the attached shell 31. In the initial state, the No. 3 spring 323 will always push the wedge 322 downward, so that the wedge 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.

[0053] like Figure 7 and Figure 82854 is rotatably mounted in the slot 43. 57. A limiting rod 2858 is provided 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 insertion hole 29. 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-in board 42, and when the plug-in 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-in board 42 and avoid the transmission assembly 28 and the plug-in board 42 from conflicting when the plug-in board 42 is inserted.

[0054] like Figure 2 and Figure 3 In the figure, an airbag strip 210 is provided between the sliding frame 26 and the top of the shell 21, an annular airbag sealing ring 211 is provided on the inner wall of the shell 21, and the annular airbag sealing ring 211 is located below the fixed frame 24. 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. After being squeezed, the airbag strip 210 will transport the gas inside the airbag strip 210 into the annular airbag sealing ring 211 through the connecting tube 212, so that the annular airbag sealing ring 211 expands and fills the space between the lampshade assembly 4 and the shell 21, thereby ensuring the sealing effect of the installation of the lampshade assembly 4 and preventing dust and rainwater from invading the street lamp.

[0055] like Figure 1 、 Figure 5 and Figure 9In the figure, the lampshade assembly 4 includes a lampshade body 41, and the two plug-in boards 42 are respectively fixed on the two opposite sides of the lampshade body 41. The inner shell 22 is provided with lighting beads 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 using the limit lock of the plug-in board 42.

[0056] During operation, since the existing street lamp lampshade is mainly installed by screws to fasten the lampshade under the lamp housing, tools are needed to assist in tightening the screws. In order to make the lampshade firmly installed, a large number of screws are used to tighten the lampshade, which makes the lampshade installation operation cumbersome and the installation speed slow, resulting in low street lamp installation efficiency. In this solution, the two plug-in boards 42 on the side of the lampshade body 41 are aligned with the two plug-in holes 29 opened in the fixing frame 24 and inserted therein. When the plug-in boards 42 are inserted into the plug-in holes 29, they enter between the transmission components 28, and when the plug-in boards 42 are inserted, they push the sliding frame 26 upward. The sliding frame 26 is squeezed and moves upward, and squeezes the No. 1 spring 27 to shrink. When the sliding frame 26 slides upward, it drives 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 rotates on the side wall of the housing 21;

[0057] At this time, when the rotating shaft 281 rotates, it drives the ratchet 324 to rotate. Under the action of the No. 3 spring 323, the wedge block 322 is engaged in the tooth groove of the ratchet 324. When the ratchet 324 rotates, the bevel of the tooth groove pushes the wedge block 322 upward. After being pushed, the wedge block 322 presses the No. 3 spring 323 upward to contract. Under the action of the No. 3 spring 323 and the wedge block 322, the ratchet 324 can only rotate in one direction, thereby engaging the gear 282 with the No. 1 rack 283, locking the No. 1 rack 283 and preventing it from moving downward. After the No. 3 spring 323 contracts, the lifting rod 321 extends upward from the attached housing 31 to lift the U-shaped cover plate 5.

[0058] As the gear 282 rotates, it drives the second rack 284 to slide on the side wall of the inner shell 22, thereby driving the latch assembly 285 at its end to slide in the slide groove 286 through the slider 287, thereby pushing the latch assemblies 285 on both sides of the two sockets 29 inward at the same time, and making the latch assemblies 285 on both sides of the sockets 29 fit on the two side edges of the plug board 42;

[0059] When the latch assembly 285 is fitted on the side of the plug board 42, the roller 2854 therein will fit on 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 toward 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 toward 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 at the same time squeeze the limit plate 2855 The second spring 2856 contracts, and when the plug-in board 42 is inserted into place, the slot 43 on its side enters the upper part of the fixed frame 24 and is 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 are 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 is fixed below the lamp housing assembly 2, and its side is 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 fixing the lampshade body 41.

[0060] When the plug-in board 42 pushes the sliding frame 26 to move upward, it squeezes the airbag strip 210 upward. After the airbag strip 210 is squeezed, the gas inside it enters the annular airbag sealing ring 211 through the connecting tube 212, so that the annular airbag sealing ring 211 expands and fills the space 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 through the connection between the lampshade and the lamp housing and affecting the use of the street lamp;

[0061] 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 324 when it moves upward to release the rotation limit of the ratchet 324. At this time, under the action of the No. 1 spring 27, the sliding frame 26 is pushed downward, and when the sliding frame 26 moves downward, it drives the No. 1 rack 283 to drive the gear 282 in the reverse direction, and the gear 282 drives the No. 2 rack 284 to be level on the fixed frame 24 again. When the sliding frame 26 moves downward, the gas in the annular airbag sealing ring 211 flows back into the airbag strip 210 through the connecting pipe 212, and then the annular airbag sealing ring 211 returns to its original state. At this time, the sliding frame 26 pushes the plug-in board 42 out from between the outer shell 21 and the inner shell 22, and the lampshade body 41 can be disassembled and removed for maintenance of the street lamp.

[0062] The cooperation achieves the effect of facilitating the installation of street lamp shades. Compared with traditional street lamp shades, the installation operation is more convenient, which effectively improves the installation efficiency of street lamp shades, and facilitates the disassembly of the shades, thereby improving the convenience of street lamp maintenance and repair.
