Technical Field

[0001] This utility model relates to the field of quick disassembly and installation technology, and in particular to a quick disassembly structure. Background Technology

[0002] In modern electronic and mechanical equipment, the quick disassembly and assembly of the housing is an important design consideration. Quick-disassembly designs not only improve equipment maintenance efficiency and reduce maintenance costs, but also enhance the user experience. Traditional quick-disassembly designs typically rely on the engagement of male and female latches. By pressing buttons on both sides of the housing, the male latch disengages from the female latch, thus completing the quick disassembly. However, this design is mainly suitable for injection-molded plastic housings. For metal housings (such as aluminum housings), due to limitations in their processing technology, it is difficult to achieve a similar structural design. Utility Model Content

[0020] This utility model proposes a quick-release structure 100.

[0021] Please see Figures 1 to 5 In one embodiment of this utility model, the quick-release structure 100 includes a housing 1, a base 2, and a disassembly assembly 3. The housing 1 has a slot 13; the base 2 has a mounting slot 21; the disassembly assembly 3 includes a button 31, an elastic element 32, and a crank 33. The crank 33 is movably connected to the bottom wall of the mounting slot 21. The elastic element 32 has a retractable section 323 and a snap-fit ​​section 322 connected to each other. The retractable section 323 is accommodated in the mounting slot 21, and the snap-fit ​​section 322 is exposed on the side wall of the mounting slot 21 and snaps into the slot 13. The button 31 is movably inserted through the bottom wall of the mounting slot 21 and is connected to the crank 33. The button 31 is configured to drive the crank 33 to compress the retractable section 323 and cause the snap-fit ​​section 322 to retract into the mounting slot 21 and disengage from the slot 13 when pressed.

[0022] In the technical solution of this utility model, the outer shell 1 is provided with a slot 13 for engaging with the snap-fit ​​section 322 of the elastic member 32 on the base 2, thereby fixing the outer shell 1 to the base 2; the base 2 is provided with a mounting groove 21 for installing the disassembly assembly 3; the button 31 is movably inserted through the bottom wall of the mounting groove 21 for triggering the disassembly action; when the outer shell 1 and the base 2 need to be connected, the slot 13 of the outer shell 1 is aligned with the snap-fit ​​section 322 of the elastic member 32 on the base 2, and when the outer shell 1 and the base 2 are placed in place, the snap-fit ​​section 322 of the elastic member 32 snaps into the slot 13 of the outer shell 1, thereby fixing the outer shell 1 to the base 2; when the outer shell 1 and the base 2 need to be connected, the snap-fit ​​section 322 of the elastic member 32 engages with ... snap-fit ​​section 322 of the base 2, thereby fixing the outer shell 1 to the base 2. When disassembling the outer casing 1 from the base 2, pressing button 31 compresses the retractable section 323 of the elastic element 32 via crank 33. Under the compression of the retractable section 323, the locking section 322 of the elastic element 32 retracts into the mounting groove 21 and disengages from the locking groove 13 of the outer casing 1. At this point, the outer casing 1 can be easily removed from the base 2, completing the disassembly. The crank 33 compresses the retractable section 323 by rotating the crank 33 to the bottom wall of the mounting groove 21. A limiting post 331 is provided on the side of the crank 33 facing away from the bottom wall of the mounting groove 21, abutting against the retractable section 323. When button 31 is pressed, it drives the crank 323. 3. Rotation drives the limiting post 331 to rotate and compress the retractable section 323, thereby causing the locking section 322 to retract into the mounting groove 21 and disengage from the locking groove 13. Alternatively, the crank 33 can be slidably connected to the bottom wall of the mounting groove 21, with a compression rod provided on the side of the crank 33 facing away from the bottom wall of the mounting groove 21. The button 31 drives the crank 33 to move linearly, thereby driving the compression rod to compress the retractable section 323, thereby causing the locking section 322 to retract into the mounting groove 21 and disengage from the locking groove 13. This utility model does not limit this. The limiting post 331 can be one or two. This utility model does not limit this, but two are provided. When the limiting post 331 is in place, the telescopic section 323 is located between the two limiting posts 331; the disassembly action is triggered by the button 31, which is simple and quick to operate and significantly improves the disassembly efficiency. It is suitable for equipment that requires frequent disassembly and assembly, such as electronic device housing 1, mechanical equipment housing 1, etc. The disassembly component 3 is integrated in the mounting slot 21 of the base 2, which does not occupy extra space and has a compact design, making it suitable for equipment with limited space; moreover, the quick-release structure 100 proposed in this application can be used for both plastic housing 1 and metal housing 1, with strong material adaptability. The design of the disassembly component 3 ensures the stability and durability of the structure, making it suitable for scenarios with frequent disassembly and installation.

[0023] To improve the stability of the quick-release structure 100, please refer to [link / reference needed]. Figure 4In one embodiment of the present invention, the disassembly assembly 3 includes two cranks 33 and two elastic members 32. The two elastic members 32 are spaced apart in the mounting groove 21. The snap-fit ​​section 322 of each elastic member 32 is exposed on the side wall of the mounting groove 21 and snaps into the snap-fit ​​groove 13. The two cranks 33 are spaced apart in the mounting groove 21 and are movably connected to the bottom wall of the mounting groove 21. The button 31 is drivenly connected to the two cranks 33. When connecting the outer shell 1 to the base 2, place the outer shell 1 on the base 2, aligning the slot 13 of the outer shell 1 with the snap-fit ​​sections 322 of the two elastic elements 32 on the base 2. When the outer shell 1 is in place, the snap-fit ​​sections 322 of the two elastic elements 32 automatically snap into the slot 13 of the outer shell 1, thus fixing the outer shell 1 to the base 2. When disassembling the outer shell 1 from the base 2, press the button 31. The button 31 drives two cranks 33 simultaneously through a transmission connection. The two cranks 33 compress the retractable sections 323 of the two elastic elements 32 respectively. Under the compression of the retractable sections 323, the snap-fit ​​sections 322 of the two elastic elements 32 retract into the mounting groove 21 and disengage from the slot 13 of the outer shell 1. At this time, the outer shell 1 can be easily removed from the base 2, completing the disassembly. The design of component 32 distributes the force when button 31 is triggered, making the force on the entire disassembly assembly 3 more even and improving the stability of the structure. The two elastic components 32 are spaced apart to ensure a more secure engagement between the locking section 322 and the locking slot 13, reducing the risk of structural failure due to single-point force. The design of the two elastic components 32 and the two cranks 33 provides redundancy, so that even if one component fails, the other component can still work normally, ensuring the reliability of the quick-release structure 100. The design of the double cranks 33 and the double elastic components 32 makes the force when button 31 is triggered evenly, reducing component wear and extending service life. The button 31 is connected to the two cranks 33, so the user only needs to press the button 31 to trigger both cranks 33 at the same time, realizing quick disassembly, which is simple and fast.

[0024] Specifically, please refer to Figure 5In one embodiment of the present invention, the disassembly assembly 3 includes two sliders 34, one side of the two sliders 34 facing each other is a guide slope 341, and the end of the button 31 near the slider 34 is formed with a sloping guide block 311. The two side walls of the sloping guide block 311 respectively move and abut against the two guide slopes 341. Each slider 34 is connected to a crank 33. The inclined guide block 311 on button 31 and the inclined guide surface 341 on slider 34 are in active contact. This design allows the pressing action of button 31 to be accurately transmitted to slider 34, thereby driving slider 34 and crank 33 to move. Through the cooperation of inclined guide block 311 and inclined guide surface 341, the pressing force of button 31 can be evenly distributed to the two sliders 34, improving the accuracy and reliability of operation. The two sliders 34 are connected to the two cranks 33 respectively. This design disperses the force when button 31 is triggered, making the force on the entire disassembly assembly 3 more even and improving the stability of the structure. The active contact between inclined guide block 311 and inclined guide surface 341 reduces the direct friction between button 31 and slider 34, extending the service life of the component. The pressing action of button 31 is directly transmitted to slider 34 through the cooperation of inclined guide block 311 and inclined guide surface 341. The user only needs to press button 31 to drive both sliders 34 at the same time, realizing quick disassembly. The dual slider 34 design reduces misoperation caused by single-point force and improves the user experience.

[0025] Please see Figure 5 In one embodiment of this utility model, each of the two sliders 34 has an inclined groove 342 on one side facing each other, and the two sides of the inclined guide block 311 are respectively accommodated in the two inclined grooves 342; the cross-sectional area of ​​the inclined guide block 311 gradually increases from the end closer to the slider 34 to the end farther away from the slider 34. The inclined groove 342 provides a precise sliding path for the inclined guide block 311, ensuring that the pressing action of the button 31 can be accurately transmitted to the slider 34, thereby driving the slider 34 to move; the cross-sectional area of ​​the inclined guide block 311 gradually increases from the end closer to the slider 34 to the end farther away from the slider 34. This design makes the force on the inclined guide block 311 in the groove more uniform, reducing jamming or wear caused by uneven force; the design of the gradually changing cross-sectional area makes the force on the inclined guide block 311 more uniform when sliding in the inclined groove 342, reducing This design prevents structural deformation or damage caused by excessive local stress. The cooperation between the inclined slide 342 and the inclined guide block 311 reduces direct friction between the button 31 and the slider 34, extending the service life of the components. The pressing action of the button 31 is directly transmitted to the slider 34 through the cooperation of the inclined guide block 311 and the inclined slide 342. The user only needs to press the button 31 to drive both sliders 34 at the same time, achieving quick disassembly. The design of the dual sliders 34 and the precise guidance of the inclined slide 342 reduce misoperation caused by single-point force, improving the user experience.

[0026] For more details, please refer to Figure 2 and Figure 4 In one embodiment of this utility model, the outer shell 1 is provided with a cavity 11, the bottom wall of the cavity 11 is provided with an opening 12, and the side wall of the cavity 11 is provided with a slot 13. The base 2 is accommodated in the cavity 11 and is partially exposed through the opening 12. Two through holes 24 are provided at intervals on the opposite side walls of the mounting groove 21. Each elastic member 32 has two limiting sections 321, two snap-fit ​​sections 322, and one retractable section 323. The two limiting sections 321 are located at both ends of the elastic member 32. Each snap-fit ​​section 322 is located between a limiting section 321 and a retractable section 323. The two limiting sections 321 respectively abut against and limit the opposite side walls of the mounting groove 21. Each snap-fit ​​section 322 passes through a through hole 24 and is exposed on the side wall of the mounting groove 21. When connecting the outer shell 1 to the base 2, the base 2 is placed into the outer shell 1, aligning the slot 13 of the outer shell 1 with the snap-fit ​​section 322 of the elastic element 32 on the base 2. When the base 2 is in place, the snap-fit ​​sections 322 of the two elastic elements 32 pass through the through holes 24 on the side wall of the mounting groove 21, protruding from the side wall of the mounting groove 21, and snap-fit ​​with the slot 13 of the outer shell 1, thus fixing the connection between the outer shell 1 and the base 2. When disassembling the outer shell 1 from the base 2, the button 31 is pressed. The inclined guide block 311 on the button 31 pushes the two sliders 34 away from each other through the inclined surface 341. The two sliders 34 drive the two cranks 33 respectively. The cranks 33 compress the retractable section 323 of the elastic element 32. Under the compression of the retractable section 323, the snap-fit ​​sections 322 of the two elastic elements 32 retract into the mounting groove 21 and disengage from the slot 13 of the outer shell 1. The outer shell 1 can then be easily removed from the base 2, completing the disassembly. The elastic element 32 has two... Each limiting segment 321 abuts against the two side walls of the mounting groove 21 to ensure that the elastic element 32 is stably fixed within the mounting groove 21, reducing the shaking and displacement of the elastic element 32 during use. Each elastic element 32 has two snap-fit ​​segments 322, which pass through the through holes 24 on the side wall of the mounting groove 21 and snap into the snap-fit ​​slots 13 of the outer shell 1, further improving the stability and reliability of the snap-fit. The two snap-fit ​​segments 322 of each elastic element 32, through their snap-fit ​​with the snap-fit ​​slots 13, ensure a more secure connection between the outer shell 1 and the base 2, reducing the risk of structural failure due to single-point stress. The design of the limiting segment 321 not only fixes the position of the elastic element 32, but also provides additional stability through its abutment against the side wall of the mounting groove 21. When the button 31 is triggered, the inclined guide block 311 on the button 31 and the guide inclined surface 341 of the slider 34 cooperate to drive the two sliders 34 simultaneously, achieving quick disassembly and simple and fast operation.

[0027] To restrict the movement path of slider 34, please refer to Figure 5In one embodiment, the disassembly assembly 3 further includes a fixing block 35, which is connected to one side wall of the mounting groove 21. The slider 34 is located between the fixing block 35 and the bottom wall of the mounting groove 21. Two limiting grooves 351 are spaced apart on the side of the fixing block 35 facing the slider 34. Each slider 34 has a sliding post 343 formed on the side facing the fixing block 35, and each sliding post 343 slides within one limiting groove 351. The sliding post 343 slides within the limiting groove 351, ensuring the precise and stable movement path of the slider 34, reducing the wobbling and offset of the slider 34 during movement. The design of the limiting groove 351 provides precise movement guidance for the slider 34, allowing the pressing action of the button 31 to be transmitted more accurately to the slider 34, thereby driving the slider 34 to move. The fixing block 35 is connected to one side wall of the mounting groove 21, providing additional support for the slider 34 and enhancing the structural stability of the entire disassembly assembly 3. The sliding post 343 slides within the limiting groove 351. The sliding within 51 further restricts the range of motion of slider 34, reducing the risk of slider 34 shifting due to external force or misoperation. The pressing action of button 31 is directly transmitted to slider 34 through the cooperation of inclined guide block 311 and inclined slide groove 342, as well as the sliding of slide column 343 within limit slide groove 351. Users only need to press button 31 to drive both sliders 34 simultaneously, achieving quick disassembly. The cooperation of limit slide groove 351 and slide column 343 reduces misoperation caused by slider 34 offset, improving user experience.

[0028] To limit the rotational stroke of crank 33, please refer to [link / reference]. Figure 4 In one embodiment, the bottom wall of the mounting groove 21 is provided with positioning abutment blocks 22 at intervals, and each positioning abutment block 22 is located at the end of the crank 33 away from the end connected to the slider 34. The positioning abutment block 22 provides a clear endpoint for the crank 33, ensuring that the crank 33 can accurately reach the predetermined position during movement, reducing misoperation caused by excessive or insufficient movement. The design of the positioning abutment block 22 ensures the accurate positioning of the crank 33 during movement, improving the motion control accuracy of the entire disassembly assembly 3. The positioning abutment block 22 provides additional support for the crank 33, reducing the shaking and offset of the crank 33 during movement, and enhancing the structural stability of the entire disassembly assembly 3. Through the limiting effect of the positioning abutment block 22, the direct friction between the crank 33 and the bottom wall of the mounting groove 21 is reduced, extending the service life of the component. The pressing action of the button 31 is directly transmitted to the slider 34 through the cooperation of the inclined guide block 311 and the inclined slide groove 342, as well as the sliding of the slide column 343 in the limiting slide groove 351, thereby driving the crank 33 to move and achieving quick disassembly. The precise limiting of the positioning abutment block 22 reduces misoperation caused by the offset of the crank 33, improving the user experience.
