[0033] 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 to this. Simple replacements that can be made by those skilled in the art without paying any creative work fall within the scope of protection of this application.

[0034] See also Figures 1 to 9The present application discloses a quick disassembly and assembly structure, including a shell, a lock and a driving member. A strip groove for the lock to move is opened at the upper end of the shell. One end of the lock protrudes from the shell through the strip groove, and the other end is located inside the shell and abuts against the driving member. The lock includes a first lock and a second lock. The driving member is arranged between the first lock and the second lock and abuts against the two locks respectively. When the driving member moves, the distance between the first lock and the second lock changes; in the specific implementation process, this scheme includes a total of two technical schemes, which use driving members of different structures to realize the movement of the lock, thereby quickly fixing and unlocking the device, facilitating the replacement of different devices, and meeting usage needs.

[0035] Option 1:

[0036] The driving member 4 includes a rotating member and a spring 43. The rotating member comprises a first rotating member 41 and a second rotating member 42, which are fixedly connected by a latch. The first rotating member 41 is located in the receiving groove of the limiting structure 3, and the second rotating member 42 abuts the lock catch 2. The second rotating member 42 has protruding abutting portions 421 at both ends, and a recessed portion 422 adjacent to the abutting portions. The spring is located above the second rotating member, and its ends are respectively connected to the first lock catch and the second lock catch. In this embodiment, the first rotating member is used to drive the second rotating member to move. When the abutting portion of the second rotating member contacts the lock buckle, as the second rotating member rotates, the distance between the two lock buckles will continue to increase, thereby achieving the unlocking effect. At this time, the spring is stretched; when the recessed portion is facing the lock buckle, due to the lack of supporting force on the lock buckle, the two lock buckles approach each other under the pulling action of the spring, achieving the locking effect; in order to ensure the further implementation of this scheme, an arc groove compatible with the abutting portion can be opened on the lock buckle, thereby ensuring that when the second rotating member contacts the lock buckle, the distance between the two lock buckles can be better adjusted while rotating.

[0037] The first and second locks have the same structure, each comprising a locking hook 21, a connecting block 22, and a curved plate 23. The locking hook 21 and curved plate 23 are respectively positioned at either end of the connecting block 22 and are fixedly connected to form an integrated structure. The locking hook 21 is shaped like a "7" and features a latching interface at its top. The curved plate 23 is positioned below the connecting block 22, dividing the space below the connecting block 22 into an inner area A and an outer area B. The locking hook 21 also includes a retaining structure 3 located below the housing 1. One side of the retaining structure 3 includes a receiving groove, within which a driving member 4 is mounted. The other side of the retaining structure 3 includes a retaining plate 31 that mates with the curved plate, movably connecting the retaining structure 3 to the housing 1. A retaining groove 32 is positioned on one side of the retaining plate, and a retaining end 11 is positioned within the housing 1 to mate with the retaining groove 32. The sidewalls of the retaining groove of the retaining structure 3 are provided with anti-slip stripes 33. In this embodiment, a lock hook is provided on the lock buckle, which makes it more convenient to fix the relevant equipment, and the arc-shaped plate under the connecting block divides the area into an inner area A and an outer area B. In this way, when the baffle of the limiting structure moves to the inner area A, the baffle abuts against the arc-shaped plate, thereby limiting the arc-shaped plates on the two lock buckles from approaching each other. When the baffle is located in the outer area B, the distance between the two lock buckles is limited from further increasing, which cooperates with the driving structure to achieve double locking.

[0038] Option 2:

[0039] The driving member 4 includes a pressing block 44, a positioning member 45, a latch 46, a fixing block 47, and a spring 43. The latches 46 are provided in multiple locations and are arranged at an angle. Both ends of the latches 46 are sleeved on a connecting shaft 48 and are movably connected to the connecting shaft 48. The positioning member 45 is fixedly connected to the pressing block 44. The positioning member 45 has a groove in the middle that fits the connecting shaft 48, and a notch on the outside that fits the latch 46. The fixing block 47 is arranged horizontally between the first and second lock catches. Both ends of the fixing block 47 have slots that fit the connecting shaft 48. The spring 43 is arranged next to the lock catch 2, with one end of the spring 43 abutting the lock catch 2 and the other end connected to the inner wall of the housing 1. In this embodiment, the position between the two locks is adjusted by pressing the pressing block. A more specific process is: when an external force acts on the pressing block, the pressing block will move upward, thereby driving the positioning piece and one end of the latch to move upward. Since the latch is a non-deformable structure, it is movably connected to the coupling of the cylindrical structure, and the latch is tilted, so that the end of the latch in contact with the fixed block will move along the slide groove, thereby abutting against the lock, pushing the lock to move outward, and at the same time squeezing the spring; when the external force disappears, the spring returns to its deformation, pushing the lock to reset, and the whole process realizes the unlocking and clamping of the object.

[0040] Similarly, the first and second lock catches share the same structure, each comprising a locking hook 21, a connecting block 22, and a curved plate 23. The locking hook 21 and curved plate 23 are respectively positioned at either end of the connecting block 22 and are fixedly connected to form an integrated structure. The locking hook 21 is shaped like a "7" with a latching interface at its top. The curved plate 23 is positioned below the connecting block 22, dividing the space below the connecting block 22 into an inner area A and an outer area B. The locking hook 21 also includes a retaining structure 3 located below the housing 1. One side of the retaining structure 3 includes a receiving groove, within which a driving member 4 is mounted. The other side of the retaining structure 3 includes a retaining plate 31 that mates with the curved plate, movably connecting the retaining structure 3 to the housing 1. A retaining groove 32 is positioned on one side of the retaining plate, and a retaining end 11 is positioned within the housing 1 to mate with the retaining groove 32. The sidewalls of the retaining groove of the retaining structure 3 are provided with anti-slip stripes. In this embodiment, a lock hook is provided on the lock buckle, which makes it more convenient to fix the relevant equipment, and the arc-shaped plate under the connecting block divides the area into area A and area B. In this way, when the baffle of the limiting structure moves to area A, the baffle abuts against the arc-shaped plate, thereby limiting the arc-shaped plates on the two lock buckles from approaching each other. When the baffle is in area B, the distance between the two lock buckles is further increased, and cooperates with the driving structure to achieve double locking. The presence of the protective stripes can facilitate the rotation of the limiting structure, and the mutual cooperation of the limiting end point and the limiting groove avoids excessive movement of the limiting structure, and also facilitates effective positioning.

[0041] See also Figure 10 To further illustrate the working process of this product, the installation assembly includes a cover plate 6 and a snap plate 5 that fits the lock. The snap plate 5 is threadedly connected to the relevant equipment via screws. The cover plate 6 is connected to the snap plate 5, securing the quick-release assembly to the relevant equipment. For example, when installing a projector, the cover plate is a U-shaped plate. First, the snap plate is fixed to the bottom of the projector with screws. Then, this product is used to clamp the snap plate in place. To adjust the angle of the projector, simply adjust the deflection angle of the U-shaped plate. When the projector needs to be replaced, simply unlock the snap plate to replace it, making the operation more convenient.
