Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0022] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0023] In one embodiment of the present invention, Figures 1 to 5As shown, a buckle for quickly disassembling and assembling a garbage bin 2 of a sweeping vehicle is provided, comprising a frame base plate 1, a mounting groove 11 is provided at the rear of the bottom surface of the frame base plate 1, the mounting groove 11 is open to the rear of the vehicle, and a rotating seat 12 is provided at the top of the opening, a garbage bin 2 is detachably connected to the mounting groove 11, a hand push rod 21 is provided at the top of the garbage bin 2, and a roller 22 is provided at the bottom, the head of the garbage bin 2 is detachably connected to the mounting groove 11, a clamping block 23 is provided at the rear of the garbage bin 2, fasteners 3 are rotatably connected to both sides of the rotating seat 12, a spring 4 is connected to the middle of the fastener 3, and the other end of the spring 4 is connected to the inner wall of the rotating seat 12, a hook 5 engaged with the clamping block 23 is provided at the bottom of the fastener 3, and a sliding surface 51 slidably matched with the clamping block 23 is provided on the outer side of the hook 5.

[0024] Furthermore, guide grooves 24 are provided at the front of both sides of the trash bin 2, and pulleys 13 are provided in the installation groove 11, which are connected to the guide grooves 24 in a rolling manner. The guide grooves 24 extend downward from the front of the side of the trash bin 2 and open at one end close to the front of the trash bin 2. Specifically, when installing the trash bin 2, the trash bin 2 is pushed into the installation groove 11 from the rear of the vehicle by the push rod 21, and the opening of the guide groove 24 at the front of the trash bin 2 contacts the pulley 13 in the installation groove 11, and then the trash bin 2 is continuously pushed deeper into the installation groove 11. During this process, the pulley 13 enters the guide groove 24 and rolls in the guide groove 24, lifting the front of the trash bin 2 until the front of the trash bin 2 abuts against the innermost wall of the installation groove 11, and then the rear of the trash bin 2 is lifted upward by lifting the push rod 21, so that the hook 5 is engaged with the block 23, so as to achieve better installation of the trash bin 2.

[0025] Furthermore, a platform 241 extends from the end of the guide groove 24, and the platform 241 is in rolling connection with the pulley 13. Specifically, when installing the trash bin 2, the trash bin 2 is pushed by the push rod 21, and the trash bin 2 is pushed into the installation groove 11 from the rear of the vehicle, and the opening of the guide groove 24 located at the head of the trash bin 2 contacts the pulley 13 in the installation groove 11, and then the trash bin 2 is continuously pushed deeper into the installation groove 11. During this process, the pulley 13 enters the guide groove 24 and rolls in the guide groove 24, lifting the head of the trash bin 2, and finally the roller 22 passes through the guide groove 24 and enters the platform 241, so that the head of the trash bin 2 can stay stably at a fixed height. When the trash bin 2 needs to be taken out, the roller 22 enters the guide groove 24 from the platform 241, which is more labor-saving to use.

[0026] Further, the fastener 3 includes a pull rod 31, and two rotating parts 32 extend upward on both sides of the pull rod 31. Both sides of the pull rod 31 extend downward and are respectively connected to the two hooks 5. The two rotating parts 32 are respectively rotatably connected to the two sides of the rotating seat 12, and the middle part of the pull rod 31 is connected to one end of the spring 4. Specifically, when the fastener 3 is used, the pull rod 31 is lifted to make the pull rod 31 do a fan-shaped movement on the rotating seat 12. By setting the pull rod 31, it is possible to achieve more labor-saving separation of the hook 5 from the block 23.

[0027] Furthermore, the rotating part 32 has a limit rod 33 extending toward the inner wall of the rotating seat 12, and the limit rod 33 performs a fan-shaped motion along the rotation center of the rotating part 32. The inner side of the rotating seat 12 is provided with a push rod 121 for stopping the limit rod 33. Specifically, when the pull rod 31 is lifted and performs a fan-shaped motion on the rotating seat 12, the limit rod 33 performs a fan-shaped motion along the rotation center of the pull rod 31 at the same time, until the limit rod 33 abuts against the push rod 121 to achieve the current effect.

[0028] Furthermore, the pull rod 31 extends outwardly with a handle 311. Specifically, the pull rod 31 can be lifted by lifting the handle 311, and the handle 311 simultaneously performs a fan-shaped motion along the rotation center of the pull rod 31, and the lever arm of the handle 311 is longer, so that using the handle 311 to lift the pull rod 31 can save effort and achieve a better use effect.

[0029] Working principle: When installing the trash bin 2, the trash bin 2 is pushed by the hand push rod 21, and the trash bin 2 is pushed into the installation groove 11 from the rear of the vehicle until the head of the trash bin 2 is installed and fixed at the innermost side of the installation groove 11, and the trash bin 2 is lifted upward by the hand push rod 21, so that the top surface of the block 23 located at the rear of the trash bin 2 contacts the hook 5 and slides with the sliding surface 51 of the hook 5. During the sliding process, the hook 5 is lifted up and the spring 4 is elastically stretched. When the sliding surface 51 completely slides over the top surface of the block 23, the support of the top surface of the block 23 is lost. Under the elastic contraction of the spring 4, the hook 5 is stuck on the bottom surface of the block 23 to fix the trash bin 2; when disassembling the trash bin 2, the hook 5 is unhooked from the block 23 by pulling the fastener 3, so that the rear of the trash bin 2 falls off, and then the trash bin 2 is dragged out by pulling the hand push rod 21, so as to realize the convenient disassembly and assembly function.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
