[0015] In order to more clearly describe the present invention, the present invention is further described below in conjunction with the accompanying drawings. Of course, the protection scope of the present invention is not limited thereto. Simple replacements that can be made by those skilled in the art without paying any creative work belong to the protection scope of the present invention.

[0016] See also Figures 1 to 7 The utility model discloses a quick disassembly and assembly structure with self-locking, including a disassembly and assembly structure and a locking structure 3. The disassembly and assembly structure includes a mounting plate 1, a lever 2 and a driving member. The lever 2 is arranged on the mounting plate 1 and connected to the driving member. The lever 2 is arranged in close contact with the mounting plate 1. Both sides of the lever 2 are provided with extended limit members 23. One end of the limit member 23 is fixedly connected with the lever 2 as an integrated structure, and the other end is provided with a limit bayonet 24. The locking structure 3 is arranged on the mounting plate 1. One end of the locking structure 3 is fixed on the mounting plate 1, and the other end is provided with a limit block 34 adapted to the limit bayonet. When the limit bayonet 24 is adapted to the limit block 34, the lever 2 is restricted from rotating. In this embodiment, a locking structure is provided, and the locking structure is used to fix the disassembly and assembly structure, so that the disassembly and assembly structure is limited during use to prevent the disassembly and assembly structure from moving and causing damage to the equipment.

[0017] The locking structure 3 includes a fixed block 31 and a locking slider 32. The fixed block 31 is arranged on the mounting plate 1 and fixedly connected to the mounting plate 1. A connecting rod is arranged on the surface of the fixed block 31, and one end of the locking slider 32 is sleeved on the connecting rod and movably connected to the fixed block 31. A weight block 33 with an extension is arranged in the middle of the locking slider 32, and the weight block 33 is integrally connected to the locking slider 32. The fixed block 31 is a bevel structure, and the side close to the middle of the mounting plate 1 is higher than the side close to the edge of the mounting plate 1. In this embodiment, since the fixed block is a bevel structure and the locking slider is connected to the weight block, due to the existence of the weight block and the set angle, when the whole structure is tilted from the horizontal to a certain angle, the force directions of the weight block and the locking slider change, so that the locking slider rotates along the bevel surface driven by the weight block, making the limiting block contact the limiting bayonet, realizing the locking of the lever; when the whole device changes from the tilted state to the horizontal state, the force directions of the weight block and the locking slider change, releasing the locking of the lever.

[0018] The disassembly and assembly structure further includes a bottom plate 4, a spring and a locking member 5. The lever 2 and the locking member 5 are respectively arranged on both sides of the bottom plate 4. There are multiple locking members 5, symmetrically distributed on the same side of the bottom plate 4. A driving member 6 is installed between the symmetrically arranged locking members 5. The middle of the driving member 6 is fixedly connected to the lever 2 and rotates under the drive of the lever 2. The two ends of the driving member 6 respectively abut against the symmetrically arranged locking members 5. The two ends of the spring are respectively connected to the symmetrically arranged locking members. Driven by the spring and the driving member 6, the symmetrically arranged locking members 5 perform reciprocating motion. The lever 2 further includes a recessed portion 22 and a contact portion 21. The contact portion 21 is arranged on both sides of the recessed portion 22 and is integrally and fixedly connected to the recessed portion 22. The recessed portion 22 is a "U" - shaped structure and is adapted to the bottom plate. The middle of the recessed portion is fixedly connected to the driving member by screws. The locking member 5 includes a base and a lock catch. The lock catch is arranged at the upper end of the base and is integrally and fixedly connected to the base. A driving groove adapted to the driving member is arranged at the lower part of the base. The driving groove is an arc - shaped structure, and a fixed pin adapted to the spring is arranged at the upper end of the driving groove. In this embodiment, the relevant equipment is clamped by the locking member to achieve effective fixation. The lever drives the driving member to move under the action of an external force, so that the locking member expands. When the external force disappears, the locking member resets under the drive of the spring, realizing the fixation and unlocking of the equipment. The existence of the recessed portion can effectively fit with the mounting plate, thus having a larger space to install structures such as the bottom plate and reducing the overall space occupation ratio.

[0019] The edge of the mounting plate 1 is provided with a motion groove 12 adapted to the lever 2, and motion baffles 13 are provided on both sides of the motion groove 12. A protective shell 14 is also included, which is arranged on the upper part of the mounting plate 1 and is fixedly connected to the mounting plate 1 by screws. In this embodiment, the motion groove and the motion baffle are provided, thereby effectively limiting the motion area of ​​the lever, and the existence of the protective shell can effectively connect with the mounting plate to form a receiving cavity, and other structures are arranged in the receiving cavity for effective protection.

[0020] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
