[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0028] Example 1

[0029] like Figures 1 to 5As shown, a quick-assemble and detachable street lamp includes a lamp pole 1 and a lamp holder connecting portion 2 for being mounted on the lamp pole 1. The lamp pole 1 is provided with a connecting seat 3, and a lifting mechanism 31 is provided in the connecting seat 3. The lifting mechanism 31 includes a pull rope 311 extending from the connecting seat 3 for driving the lamp holder connecting portion 2 to rise and fall. The lamp pole 1 is provided with multiple groups of guide fixing structures 4 distributed at intervals along the circumference. The lamp holder connecting portion 2 is provided with multiple fixing portions 21 corresponding to the multiple groups of guide fixing structures 4 one by one. The guide fixing structure 4 includes a guide inclined plate for mounting. 41 and a disassembly guide inclined plate 42. The bottom end of the disassembly guide inclined plate 42 cooperates with the installation guide inclined plate 41 to form a fixed position 43 for positioning the fixing part 21. The pull rope 311 drives the lamp holder connecting part 2 to rise. When installing, the lower side of the installation guide inclined plate 41 cooperates with the guide of the fixing part 21 to push the lamp holder connecting part 2 and the pull rope 311 to deviate circumferentially. A first baffle 12 is provided on the lamp pole 1 above the fixed position 43. A blocking mechanism 32 is provided on the lamp pole 1 to prevent the lamp holder connecting part 2 from rising. When the fixing portion 21 is disengaged from the fixing position 43 by the pull rope 311, a disassembly space is formed between the blocking mechanism 32 and the installation guide inclined plate 41 so that the fixing portion 21 can be located in the reset space. When the fixing portion 21 is located in the reset space, it is located on one side of the first baffle 12 and is circumferentially aligned with the first baffle 12, so that the fixing portion 21 moves toward the first baffle 12 under the circumferential reset action of the pull rope 311. When the fixing portion 21 is disengaged from the fixing position 43 by the pull rope 311, a disassembly space is formed between the blocking mechanism 32 and the disassembly guide inclined plate 42 so that the fixing portion 21 can move circumferentially to disengage from the guide fixing structure 4. At the same time, the pull rope 311 can be a rope made of a material such as a steel rope that can be purchased on the market. The blocking structure can block the lamp mounting ring at the position corresponding to the fixing structure during the rising process of the lamp mounting ring. In this way, the installer does not need to observe the position of the lamp mounting ring with the naked eye. When the lamp mounting ring cannot continue to move upward, it can be determined that the position of the lamp mounting ring corresponds to the fixing structure.

[0030] Furthermore, the blocking mechanism 32 includes two limiting rods 321 located on the surface of the lamp pole 1 and symmetrically arranged. A nut 11 is provided on the surface of the lamp pole 1. The limiting rod 321 includes a screw 322 that is detachably connected by threaded coupling with the nut 11. The detachability of the screw 322 saves the time of replacing the limiting rod 321 when the screw 322 is used for a long time. The lamp holder connecting part 2 includes a lamp holder mounting ring 22 that is sleeved on the surface of the lamp pole 1. Fixed pulleys 36 are provided at both ends of the connecting seat 3. The two ends of the pull rope 311 are respectively wrapped around the corresponding fixed pulleys 36 and connected to the lamp holder connecting part 2. The lifting mechanism 31 also includes a movable lifting structure 312 movably connected to the middle end of the pull rope 311. When the movable lifting structure 312 is pulled, the lamp holder connecting part is driven by the pull rope 311 2 moves upward because the movable lifting structure 312 can move on the pull rope 311. When the user pulls the movable lifting structure 312 to move the pull rope 311 with the lamp holder mounting ring 22, the movable lifting structure 312 can balance the force on the pull rope 311, so that when the pull rope 311 pulls the lamp holder mounting ring 22, uneven force will not occur, which will cause the lamp holder mounting ring 22 to tilt. The movable lifting structure 312 includes a movable pulley 313 that cooperates with the pull rope 311. The surface of the movable pulley 313 is provided with a mounting shell 314. The bottom end of the mounting shell 314 is movably connected to a movable buckle 315. A tension rope 316 for driving the pull rope 311 is installed in the movable buckle 315. The fixed part 21 includes a guide rod 23 that can cooperate with the installation guide inclined plate 41 and the removal guide inclined plate 42.

[0031] When the lamp holder mounting ring 22 is to be installed, the lamp holder mounting ring 22 is pulled upward by the pull rope 311. When the lamp holder mounting ring 22 moves, the guide rod 23 will contact the installation guide inclined plate 41. When the lamp holder mounting ring 22 continues to move, the guide rod 23 will move upward along the guide path of the installation guide inclined plate 41 and drive the lamp holder mounting ring 22 to rotate. When the lamp holder mounting ring 22 rotates, it will also rotate with the pull rope 311, so that the pull rope 311 has a tendency to rotate and reset along the circumferential direction. When the lamp holder mounting ring 22 moves upward, it will contact the screw rod 322, so that the lamp holder mounting ring 22 cannot continue to move, and the guide rod 23 will move upward along the guide path of the installation guide inclined plate 41. When the rod 23 is in the installation position, the guide rod 23 is out of the guide path of the installation guide ramp 41, allowing the pull rope 311 to start to rotate and reset in the circumferential direction. When the pull rope 311 is reset, it pulls the lamp holder mounting ring 22 to rotate toward the original position. However, during the reset process of the lamp holder mounting ring 22, the guide rod 23 contacts the first baffle 12, causing the pull rope 311 to continue to maintain the trend of rotating and resetting in the circumferential direction. When the guide rod 23 contacts the first baffle 12, the pull rope 311 is released, allowing the lamp holder mounting ring 22 to fall, thereby allowing the guide rod 23 to fall into the fixed position 43, thereby completing the installation of the lamp holder mounting ring 22.

[0032] When the lamp holder mounting ring 22 is to be disassembled, the movable buckle 315 is pulled downward, and the movable buckle 315 moves with the movable pulley 313. When the movable pulley 313 allows the pull rope 311 to move upward with the lamp holder mounting ring 22, the movable pulley 313 can balance the force of the pull rope 311, so that when the pull rope 311 pulls the lamp holder mounting ring 22, there will be no uneven force and the lamp holder mounting ring 22 will not tilt. When the lamp holder mounting ring 22 moves upward and leaves the fixed position 43, the pull rope 311 will start to continue to move along the circumferential direction. Reset, so that the guide rod 23 starts to move from the fixed position 43 to the disassembly position along the path of disassembling the guide inclined plate 42, until the lamp holder mounting ring 22 contacts the limit rod 321, the guide rod 23 will move to the disassembly position, at this time the pull rope 311 will continue to lead the guide rod 23 out of the area of ​​the guide fixing structure 4 according to the trend of circumferential reset, when the guide rod 23 is out of the guide fixing structure 4, release the movable buckle 315, and the lamp holder mounting ring 22 starts to fall, so that the fixation of the lamp holder mounting ring 22 can be released.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the blocking structure is as follows Figures 6 to 7 The first baffle plate 33 is located on one side of the first baffle plate 12, and the blocking mechanism 32 further includes a second baffle plate 34 located on the other side of the first baffle plate 12 and a second baffle plate 35 located on the side of the second baffle plate 34 away from the first baffle plate 12. The blocking mechanism in this example realizes the installation of the lamp holder mounting ring 22 when the guide rod 23 moves upward. After the guide rod 23 leaves the guide path of the installation guide inclined plate 41, the guide rod 23 will contact the first baffle plate 33. The guide rod 23 is now in the installation position. The pull rope 311 will start to rotate and reset in the circumferential direction, allowing the guide rod 23 to contact the first baffle plate 12, so that the lamp holder mounting ring 22 and the pull rope 311 continue to maintain the trend of resetting in the circumferential direction. When the guide rod 23 contacts the first baffle plate 12, the movable buckle 315 is released, causing the lamp holder mounting ring 22 to fall, allowing the guide rod 23 to enter the fixed position 43, and completing the installation of the lamp holder mounting ring 22.

[0035] When disassembling is required, the movable buckle 315 is pulled downward again, so that the lamp holder mounting ring 22 is pulled up by the pull rope 311, and the guide rod 23 leaves the fixed position 43 and contacts the second baffle 34, so that the guide rod 23 is located in the disassembly position. When the guide rod 23 is in the disassembly position, the pull rope 311 will continue to lead the guide rod 23 out of the area of ​​the guide fixing structure 4 according to the trend of circumferential reset. After the guide rod 23 is out of the guide fixing structure 4, the movable buckle 315 can be loosened to allow the lamp holder mounting ring 22 to fall, so as to disassemble the lamp holder mounting ring 22.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
