[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a quick-release lamp body rear cover, including a lamp holder 1 and a cover 4, wherein the top end of the lamp holder 1 and the bottom end of the cover 4 are in contact.

[0030] The mounting and disassembly assembly 2 includes a mounting cover 21 fixedly connected to the cover frame 4. The mounting cover 21 has a threaded groove 22 inside, and a connecting post 23 is threadedly connected to the threaded groove 22. An extension rod 24 is fixedly connected inside the connecting post 23. The lamp holder 1 has a slot 25 inside, and the outer side of the extension rod 24 is rotatably connected to the slot 25. The top of the lamp holder 1 has a sliding groove 26, and the outer side of the extension rod 24 is slidably connected to the sliding groove 26. The bottom of the mounting cover 21 has a receiving groove 27, and the outer side of the extension rod 24 engages with the inside of the receiving groove 27.

[0031] The lamp holder 1, as the main supporting structure of the lamp body, bears various internal components and provides a stable mounting base for the entire lamp body. It also contacts the cover frame 4, forming the outer shell structure of the lamp body and protecting the internal components. The cover frame 4, in conjunction with the lamp holder 1, forms the outer shell of the lamp body, sealing and protecting the interior of the lamp body. It also provides a mounting base for installing and removing component 2, facilitating quick installation and removal of the lamp body's rear cover. The mounting cover 21 is fixedly connected to the cover frame 4, providing an installation position for the threaded groove 22. It also engages with the extension rod 24 through the receiving groove 27, providing a limiting and fixing function to ensure the stability of the connecting post 23 and the extension rod 24 during installation and removal. The threaded groove 22 engages with the thread on the connecting post 23, enabling the fixing and removal of the connecting post 23 on the mounting cover 21 through a threaded connection, providing a simple connection method. The connecting post 23 connects to the threaded groove 22 through threads, connecting the mounting cover 21 to the lamp holder 1. Simultaneously, the extension rod 24 is internally fixed, transmitting force and connecting the cover frame 4 to the lamp holder 1. The lamp holder 1 is fixed together to realize the installation of the lamp body back cover. The extension rod 24 is fixedly connected inside the connecting column 23, and is rotatably connected to the slot 25 of the lamp holder 1 on the outside, and slidably connected to the slide groove 26. It is engaged with the receiving groove 27, which plays a role in limiting and guiding, ensuring the smoothness and stability of the connecting column 23 during installation and disassembly. The slot 25 is opened inside the lamp holder 1 for rotatably connecting with the outside of the extension rod 24, providing the installation position and movement space for the extension rod 24, ensuring the stability and flexibility of the extension rod 24 during installation and disassembly, so that it can be stably connected in the slot 25 during installation. The slide groove 26 is opened at the top of the lamp holder 1 for slidably connecting with the outside of the extension rod 24, providing a guiding role for the extension rod 24, ensuring the linear movement of the extension rod 24 during installation and disassembly, and preventing the extension rod 24 from deviating or jamming during movement. The receiving groove 27 is opened at the bottom of the mounting cover 21 for engaging with the outside of the extension rod 24, which facilitates disassembly.

[0032] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the resistance component 3 includes two grooves 31 on both sides of the lamp holder 1. A slider 32 is slidably connected to the groove 31. A push rod 33 is fixedly connected to one end of the slider 32. An air duct 34 is slidably connected to the end of the push rod 33 away from the slider 32. An air supply pipe 35 is fixedly connected inside the lamp holder 1. The end of the air duct 34 away from the push rod 33 is fixedly connected inside the lamp holder 1 and connected to the air supply pipe 35. An air bladder ring 36 is fixedly connected to one end of the air supply pipe 35. The outer side of the air bladder ring 36 engages with the bottom end of the slider 32.

[0033] Slide groove 2 31, located on both sides of the lamp holder 1, provides a sliding track for slider 32, limiting the movement direction of slider 32 and ensuring that slider 32 can slide stably along a predetermined path. Simultaneously, it cooperates with slider 32 to support and guide push rod 33 and subsequent structures. Slide 32 is slidably connected to slide groove 2 31, serving as a connecting component between push rod 33 and slide groove 2 31, transmitting the pushing or pulling force of push rod 33 to slide groove 2 31. One end is fixedly connected to push rod 33, and the other end engages with airbag ring 36, serving to transmit force and limit movement. Push rod 33 is fixedly connected to one end of slider 32, and the end away from slider 32 is slidably connected inside airbag conduit 34. The sliding of push rod 33 compresses or releases the gas inside airbag conduit 34, thereby adjusting the expansion or contraction of airbag ring 36, and thus affecting the resistance between slider 32 and slide groove 2 31. Airbag conduit 34... One end is slidably connected to the push rod 33, and the other end is fixedly connected to the inside of the lamp holder 1 and connected to the gas supply pipe 35. As a gas transmission channel, it transmits the gas pressure generated by the sliding of the push rod 33 to the gas supply pipe 35, thereby affecting the state of the airbag ring 36. The gas supply pipe 35 is fixedly connected to the inside of the lamp holder 1, with one end connected to the airbag conduit 34 and the other end connected to the airbag ring 36. It is responsible for transmitting the gas pressure transmitted from the airbag conduit 34 to the airbag ring 36, causing the airbag ring 36 to expand or contract, thereby changing the resistance between the slider 32 and the second slide groove 31. The airbag ring 36 is fixedly connected to one end of the gas supply pipe 35, and its outer side engages with the bottom end of the slider 32. When the airbag ring 36 expands, it fits tightly with the bottom end of the slider 32, increasing the friction between the slider 32 and the second slide groove 31 and providing resistance. When the airbag ring 36 contracts, the friction between the slider 32 and the second slide groove 31 decreases, making it easier for the slider 32 to slide.

[0034] Working principle:

[0035] like Figure 1 - Figure 7 As shown:

[0036] In use: First, the mounting cover 21 is fixedly connected to the cover frame 4, providing an installation position for the threaded groove 22. When the cover frame 4 needs to be installed, the connecting post 23 is threadedly connected to the threaded groove 22, which in turn drives the extension rod 24 to slide downwards. The outer side of the extension rod 24 is rotatably connected to the slot 25 and simultaneously slidably connected to the slide groove 26, thus bringing the cover frame 4 into contact with the lamp holder 1. At this time, the outer side of the extension rod 24 engages with the inside of the receiving groove 27, ensuring the stability of the connecting post 23 and the extension rod 24 after installation. When the cover frame 4 needs to be disassembled, the connecting post 23 is rotated in the opposite direction, causing the extension rod 24 to slide out from the slot 25 and the slide groove 26, allowing for easy disassembly of the cover frame 4. This achieves quick disassembly and assembly of the lamp body rear cover. Secondly, the slide... Block 32 is slidably connected to the second slide groove 31, providing support and guidance for push rod 33. When cover frame 4 is installed or removed, push rod 33 is subjected to external force and slides in airbag conduit 34, thereby compressing or releasing the gas in airbag conduit 34. Airbag conduit 34 transmits gas pressure to air delivery pipe 35, which can drive airbag ring 36 to expand or contract. When airbag ring 36 expands, its outer side is tightly fitted with the bottom end of slider 32, increasing the friction between slider 32 and second slide groove 31, providing resistance and preventing cover frame 4 from suddenly closing or opening. When airbag ring 36 contracts, the friction between slider 32 and second slide groove 31 decreases, making it easier for slider 32 to slide, thereby achieving stable installation and removal of cover frame 4.
