[0034] Reference Figures 1-4 This utility model provides a quick-assembly and disassembly structure for a bicycle basket, used for quickly engaging or disengaging the basket. It includes a base frame 1 with a side portion 101; an assembly / disassembly frame 2; and a rotating clamp 3, which is swung and mounted on the assembly / disassembly frame 2. The rotating clamp 3 has a first engagement groove 301 for accommodating the side portion 101. The rotating clamp 3 is configured such that, after swaying, the side wall of the first engagement groove 301 engages with or disengages from the side portion 101.

[0035] In this embodiment, when the basket needs to be installed, the mounting / dismounting frame 2 is aligned with the base frame 1, and the locking piece 3 is swung and rotated to align the first locking groove 301 with the side part 101. Then, the locking piece 3 is swung and rotated again to engage the side wall of the first locking groove 301 with the side part 101, thus securing the basket. When the basket needs to be removed, the locking piece 3 is swung and rotated in the opposite direction to disengage the side wall of the first locking groove 301 from the side part 101, allowing the basket to be removed. This device has a simple structure and is easy to operate, requiring no complex tools or cumbersome steps, allowing for quick assembly and disassembly of the basket. The swinging design of the locking piece 3 makes the engagement and disengagement actions rapid and direct, greatly improving assembly and disassembly efficiency. This quick assembly and disassembly structure allows users to flexibly replace the basket according to actual needs, adapting to different usage scenarios.

[0036] Furthermore, one end of the base frame 1 is positioned as the head end 103, and the other end is defined as the tail end 104. The base frame 1 also has a middle beam 102, which is located on the side of the disassembly frame 2 near the tail end 104. The disassembly frame 2 has a hook 201, which has a second locking groove 202. The opening of the second locking groove 202 faces the tail end 104. The disassembly frame 2 is configured such that, after being installed on the base frame 1, the middle beam 102 is engaged with the second locking groove 202.

[0037] In this embodiment, during installation, the disassembly frame 2 is pushed towards the base frame 1, causing the middle beam 102 to move along the tail end 104 and engage with the second locking groove 202. During disassembly, force is applied in the opposite direction, causing the middle beam 102 to disengage from the second locking groove 202. The engaging engagement between the middle beam 102 and the hook 201 further enhances the stability of the connection between the disassembly frame 2 and the base frame 1. The specific design of the locking direction makes it less likely to accidentally disengage during use, improving safety. The installation and disassembly actions are simple and direct, requiring no complex operations, thus improving work efficiency. This structural design helps to distribute stress and extends the service life of the quick-disassembly structure of the basket.

[0038] Furthermore, the side wall of the first snap-fit ​​groove 301 has an arc-shaped snap-fit ​​surface 303. The first snap-fit ​​groove 301 is configured such that, after snapping with the side portion 101, the arc-shaped snap-fit ​​surface 303 abuts against the side portion 101.

[0039] In this embodiment, during the snap-fit ​​process, the rotating locking member 3 swings, and the first snap-fit ​​groove 301 accommodates the side portion 101. After the snap-fit ​​is completed, the arc-shaped locking surface 303 tightly abuts against the side portion 101. The design of the arc-shaped locking surface 303 increases the contact area with the side portion 101, improving the stability and firmness of the snap-fit. The arc shape can better disperse the stress during snap-fit, reducing damage to components and extending service life. This makes the snap-fit ​​action smoother, reducing the difficulty and resistance of snap-fit. It enhances the reliability of the quick-release structure of the basket, ensuring that the basket is not easily loosened during use.

[0040] Furthermore, the opening of the first snap-fit ​​groove 301 also has a locking part 304 on both sides. The locking part 304 is connected to the arc-shaped snap-fit ​​surface 303. The first snap-fit ​​groove 301 is configured such that after it snaps into the side part 101, the locking part 304 abuts against the bottom of the side part 101.

[0041] In this embodiment, during the snap-fit ​​operation, rotating the locking member 3 causes the side portion 101 to enter the first snap-fit ​​groove 301. After snap-fitting, the locking part 304 tightly abuts against the bottom of the side portion 101. The locking part 304 enhances the locking effect of the snap-fit, further preventing the side portion 101 from accidentally dislodging from the first snap-fit ​​groove 301. In conjunction with the arc-shaped locking surface 303, it provides double restraint from the side and bottom of the side portion 101, greatly improving the stability and reliability of the snap-fit. This allows the basket to withstand greater vibration and impact during use, reducing the likelihood of loosening or falling off. It also enhances the safety of the quick-release structure of the basket, ensuring the safety of the loaded items.

[0042] Furthermore, it also includes a rotating transmission block 4, which is disposed on the rotating shaft of the rotating clamp 3. The rotating transmission block 4 rotates synchronously with the rotating clamp 3. The rotating transmission block 4 has a locking part 401. The sliding member 5 is slidably disposed on the disassembly frame 2. The sliding member 5 has a transmission groove 501. The locking part 401 is located in the transmission groove 501. The sliding member 5 is configured such that after sliding, it drives the rotating clamp 3 to rotate through the locking part 401.

[0043] In this embodiment, the slider 5 acts as the active component. When a locking operation is required, the user actively pushes the slider 5 to slide along the disassembly frame 2. During the sliding process, the transmission slot 501 drives the rotating transmission block 4 to rotate through the locking part 401, thereby causing the rotating locking part 3 to rotate and achieve locking with the side part 101. When the locking is to be released, the user pushes the slider 5 in the opposite direction, which drives the rotating locking part 3 to rotate in the opposite direction through the same transmission method, thereby releasing the locking. The active sliding operation of the slider 5 allows the user to control the locking and unlocking process more intuitively and conveniently, making the operation more intuitive. Because the slider 5 actively applies force, the transmission process is more stable and reliable, ensuring the accurate execution of locking and unlocking actions. The active sliding design reduces the difficulty of operation, as the user does not need to exert effort to directly rotate the rotating locking part 3, reducing the operational burden. It improves the efficiency of disassembling and assembling the basket, saves operation time, and enhances the convenience for users in actual use.

[0044] Furthermore, two transmission slots 501 are provided on both sides of the sliding member 5, and there are two rotating transmission blocks 4 and two rotating clamps 3, which are provided on both sides of the disassembly and assembly frame 2 in pairs.

[0045] In this embodiment, when the sliding member 5 slides, the transmission slots 501 on both sides simultaneously drive the corresponding rotating transmission blocks 4 to rotate, thereby causing the rotating clamps 3 on both sides to rotate synchronously, realizing the engagement or disengagement with the side edge 101 of the base frame 1. The paired transmission slots 501, rotating transmission blocks 4, and rotating clamps 3 on both sides make the force of engagement and disengagement more uniform, improving the stability and reliability of the structure. The synchronous operation of the double-sided design can ensure the balance of the basket during the assembly and disassembly process, reducing structural deformation or damage caused by uneven force on one side. It enhances the firmness of the connection between the basket and the base frame, and can better withstand external forces from all directions during use, improving safety. The synchronous action on both sides improves the efficiency of assembly and disassembly, making the operation faster and more convenient. This symmetrical structural design is aesthetically pleasing and helps to improve the service life and applicability of the entire quick assembly and disassembly structure of the basket.

[0046] Furthermore, the assembly / disassembly frame 2 also has a sliding guide groove 205 and a pull rod 6. The pull rod 6 is slidably disposed in the sliding guide groove 205, with one end of the pull rod 6 disposed on the sliding member 5 and the other end extending out of the sliding guide groove 205.

[0047] In this embodiment, when the sliding member 5 needs to be slidable, one end of the pull rod 6 extending through the sliding guide groove 205 is pulled or pushed, causing the pull rod 6 to slide within the sliding guide groove 205, thereby allowing the sliding member 5 to slide along a predetermined direction. The sliding guide groove 205 provides an accurate track for the sliding of the pull rod 6, ensuring the straightness and stability of the sliding action. The pull rod 6 facilitates operation from outside the assembly / disassembly frame 2, making the operation more convenient and intuitive. It effectively limits the sliding range of the pull rod 6, preventing excessive sliding that could lead to structural damage or operational errors. This structural design improves the precision and controllability of the operation, making the assembly / disassembly process of the basket more accurate and efficient.

[0048] Furthermore, it also includes a first elastic element 7, which is sleeved on the pull rod 6. One end of the first elastic element 7 acts on the sliding element 5, and the other end acts on the inner wall of the sliding guide groove 205, providing a force for the sliding element 5 to slide in the direction of the tail end 104.

[0049] In this embodiment, under normal conditions, the first elastic element 7 is in a balanced state of extension or compression. Its elastic force acts on the sliding element 5, causing the sliding element 5 to drive the rotating locking element 3 to remain in the locked position, ensuring a secure connection between the basket and the base frame. When it is necessary to disassemble or assemble the basket, external force pushes the sliding element 5 to overcome the elastic force of the first elastic element 7, causing the rotating locking element 3 to unlock. The first elastic element 7 ensures that the rotating locking element 3 remains locked, enhancing the stability and safety of the basket after installation and preventing accidental unlocking during use. No additional locking device is required, simplifying the structure and reducing costs and the probability of failure. The stable locking state reduces the risk of loosening due to vibration or external impact, extending the service life of the basket. The elastic buffering effect of the elastic element absorbs some of the external impact, protecting the locking structure and further improving reliability.

[0050] Furthermore, the end of the pull rod 6 that extends out of the sliding guide groove 205 has a pull ring portion 601.

[0051] In this embodiment, the user hooks or pulls the pull ring 601 with their finger, causing the pull rod 6 to slide within the sliding guide groove 205, thereby realizing the sliding operation of the slider 5 and controlling the engagement or disengagement of the rotating locking piece 3 with the base frame 1. The design of the pull ring 601 provides the user with a clear and convenient point of force application, making operation easier and more intuitive. It increases the contact area with the fingers, reduces local pressure on the fingers, and improves operational comfort. It facilitates operation in various situations, whether using one hand or wearing gloves. The conspicuous pull ring 601 makes the operation position more clearly visible, improving the accuracy and efficiency of operation.

[0052] Furthermore, the mounting frame 2 also has a mounting part 206, which is used to mount the mounting frame 2 onto the basket.

[0053] In this embodiment, the mounting bracket 2 is fixedly installed on the basket using screws, rivets, or other suitable connectors via the mounting part 206. The specialized mounting part 206 ensures a more secure connection between the mounting bracket 2 and the basket, preventing loosening or detachment during use. This facilitates the installation of the mounting bracket 2 on the basket, improving installation efficiency and accuracy. The standardized design of the mounting part 206 facilitates mass production and assembly, reducing production costs. It ensures the reliability of the connection between the basket and the base frame, improving the overall safety of the handcart. It provides a stable foundation for the rapid assembly and disassembly of the basket, making the process smoother and more efficient.
