Description

Technical Field

[0001] This utility model relates to a mechanical connection device, and more particularly to a connecting buckle. Background Technology

[0002] A latch is a common mechanical connection device, typically consisting of a rotating connector (such as a pivot or hinge) and a latch body (usually with a latching tongue or engaging structure). It is used to achieve a releasable connection and fixation between two components. Its working principle involves rotating or sliding the latch body to engage or disengage with the locking seat on the corresponding component, thus enabling quick switching between connection states. This structure is characterized by its ease of operation and reliable connection, and is widely used in the closure and fixation of lids, doors, lighting fixtures, and various industrial equipment.

[0003] Taking tri-proof lights as an example, their lampshades and bodies are often connected by a latch structure to achieve sealing and quick assembly / disassembly. However, in practical applications, ordinary latches have significant drawbacks: when the latch is open (i.e., not connected), due to the lack of self-positioning capability, it is prone to accidental rotation or swinging under gravity or external vibration, failing to maintain a stable opening angle. This forces workers to manually support the latch to prevent it from closing on its own during installation or maintenance, increasing operational complexity, reducing work efficiency, and potentially causing injury due to accidental closure, or leading to improper lampshade installation or inadequate sealing. Especially in confined spaces or high-altitude work environments, where operator movement is restricted, these problems further amplify the installation difficulty and safety hazards. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a simple connecting buckle that can be suspended at a certain position when not in a connected state.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A connecting buckle includes a rotating connector and a buckle body. The rotating connector is rotatably connected to the buckle body. A hovering mechanism is provided between the rotating connector and the buckle body. When the buckle body is not in a connected state, the hovering mechanism enables the buckle body to remain hovered at at least one position during its opening stroke.

[0006] One end of the rotating connector is provided with a first rotating shaft, and the upper end of the hook and loop body is provided with bent connecting walls on opposite sides. The two connecting walls are arranged in parallel and spaced apart. The two ends of the first rotating shaft are rotatably inserted into the corresponding connecting walls so that the hook and loop body is rotatably connected to the rotating connector.

[0007] The rotating connector includes a first connecting piece, one end of which is provided with the first rotating shaft, and the connecting wall is provided with a rotating connecting hole. The two ends of the first rotating shaft are respectively rotatably inserted into the corresponding rotating connecting holes. The first rotating shaft is a hollow shaft with a through cavity extending along the axial direction. An opening groove extending along the axial direction is provided on the side wall of the first rotating shaft. The opening groove is connected to the through cavity. The opening groove makes the first rotating shaft form two ends that are not connected to each other in the radial direction. The first connecting piece is fixedly connected to one of the ends.

[0008] The hovering mechanism includes at least one hovering stop protrusion protruding from the connecting wall and a hovering stop wall provided on the first connecting piece. The first connecting piece can rotate synchronously with the first rotating shaft and drive the hovering stop wall to move synchronously. When the suspension stop wall moves to abut against the suspension stop protrusion at the corresponding position, the buckle body is stopped and held in the suspension position. When it is necessary to release the suspension, force is applied to drive the rotating connector to continue rotating. The suspension stop protrusion presses against the suspension stop wall and the first connecting piece. This pressing force forces the end fixed to the first connecting piece to undergo elastic deformation and move closer to the other end, thereby releasing stress through the opening groove. Subsequently, the suspension stop wall can pass over the suspension stop protrusion, thus releasing the suspension.

[0009] The suspension stop wall is two opposite end walls of the first connecting piece along the axial direction of the first rotating shaft. The first connecting piece is disposed between the two connecting walls. The suspension stop protrusion is raised on the inner end face of the connecting wall. For the same suspension position, the suspension stop protrusions on the two connecting walls are arranged opposite each other, and the straight-line distance between the two opposite suspension stop protrusions is less than the width of the first connecting piece in the axial direction along the first rotating shaft.

[0010] The first connecting plate extends outward from both ends along the axial direction of the first rotating shaft to form the suspension stop wall. A rotation sliding groove is formed between the suspension stop wall and the corresponding end of the first rotating shaft. The connecting wall is rotatably disposed in the corresponding rotation sliding groove. The suspension stop protrusion is protruding from the rear wall surface of the connecting wall and stops by abutting against the suspension stop wall.

[0011] The two opposite end faces of the suspension stop protrusion that abut against the suspension stop wall are arc-shaped surfaces.

[0012] A second connecting piece is connected to the first connecting piece, and a second rotating shaft is provided on the second connecting piece.

[0013] The lower end of the buckle body is rolled inward to form a hook portion.

[0014] Compared with the prior art, the advantages of this utility model are: simple structure, by setting a suspension mechanism between the rotating connector and the buckle body, the buckle body can be automatically kept stable at a specific position of the opening stroke without manual support, avoiding the risk of pinching injury caused by accidental closure of the buckle during operation, especially in restricted working environments such as high altitude and narrow space, significantly reducing safety hazards and effectively improving the safety and convenience of operation.

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] Example 1: As shown in the figure, a connecting buckle includes a rotating connector 1 and a buckle body 2. The rotating connector 1 and the buckle body 2 are rotatably connected. A hovering mechanism is provided between the rotating connector 1 and the buckle body 2. When the buckle body 2 is not in the connected state, the hovering mechanism can keep the buckle body 2 hovering at at least one position in the opening stroke.

[0018] In this specific embodiment, a first rotating shaft 3 is provided at one end of the rotating connector 1, and bent connecting walls 20 are respectively provided on opposite sides of the upper end of the hook and loop body 2. The two connecting walls 20 are arranged in parallel and spaced apart. The two ends of the first rotating shaft 3 are rotatably inserted into the corresponding connecting walls 20 so that the hook and loop body 2 is rotatably connected to the rotating connector 1. The structure is stable and reliable. Through the cooperation of the two parallel and spaced connecting walls 20 and the first rotating shaft 3, a stable and evenly stressed rotation fulcrum is provided for the hook and loop body 2, ensuring the structural strength and durability of the entire hook and loop during operation.

[0019] In this specific embodiment, the rotating connector 1 includes a first connecting piece 11, one end of which is provided with a first rotating shaft 3, and the connecting wall 20 is provided with a rotating connecting hole 21, and the two ends of the first rotating shaft 3 are respectively rotatably inserted into the corresponding rotating connecting hole 21. The first rotating shaft 3 is a hollow shaft with a through cavity 30 extending along the axial direction. An axially extending opening groove 31 is provided on the side wall of the first rotating shaft 3, connecting the opening groove 31 to the through cavity 30. The opening groove 31 creates two radially unconnected ends of the first rotating shaft 3. The first connecting piece 11 is fixedly connected to one of these ends. Designing the first rotating shaft 3 as a hollow shaft with an opening groove 31 cleverly endows the shaft with local elasticity, providing the core structural foundation for the subsequent hovering mechanism to achieve the "elastic deformation-overtake-reset" function, which is crucial for achieving hovering.

[0020] In this specific embodiment, the hovering mechanism includes at least one hovering stop protrusion 22 protruding from the connecting wall 20 and a hovering stop wall 111 disposed on the first connecting piece 11. The first connecting piece 11 can rotate synchronously with the first rotating shaft 3 and drive the hovering stop wall 111 to move synchronously. When the suspension stop 111 moves to abut against the corresponding suspension stop protrusion 22, the latch body 2 is stopped and held in the suspended position. When it is necessary to release the suspension, force is applied to drive the rotating connector 1 to continue rotating. The suspension stop protrusion 22 presses against the suspension stop 111 and the first connecting piece 11. This pressing force forces the end fixed to the first connecting piece 11 to undergo elastic deformation and move towards the other end, thereby releasing stress through the opening groove 31. Subsequently, the suspension stop 111 can pass over the suspension stop protrusion 22, thus releasing the suspension. The suspension function is clear: by abutting against the suspension stop 111 and the suspension stop protrusion 22, the latch body 2 can be effectively locked in a specific open position, solving the problem of accidental swinging. The release method is ingenious: the inherent elastic deformation of the first rotating shaft 3 is used to release stress, so that the suspension can be released smoothly and easily. The operation is labor-saving and does not require complicated additional unlocking parts. The structure is simple and efficient.

[0021] In this specific embodiment, the suspension stop wall 111 consists of two opposite end walls of the first connecting piece 11 along the axial direction of the first rotating shaft 3. The first connecting piece 11 is disposed between the two connecting walls 20, and the suspension stop protrusion 22 protrudes from the inner end face of the connecting wall 20. For the same suspension position, the suspension stop protrusions 22 on the two connecting walls 20 are opposite to each other, and the straight-line distance between the two oppositely disposed suspension stop protrusions 22 is less than the width of the first connecting piece 11 in the axial direction along the first rotating shaft 3. Bidirectional stop, strong stability: The two opposite suspension stop protrusions 22 jointly clamp the two ends of the first connecting piece 11, providing symmetrical constraint force to prevent the buckle body 2 from swaying or deflecting left and right in the suspension position, maintaining absolute stability. Compact structure: The stop function is integrated into the existing connecting wall 20 and the first connecting piece 11, making full use of space without increasing the overall structural volume.

[0022] In this specific embodiment, the two opposing end faces of the suspension stop protrusion 22 that abut against the suspension stop wall 111 are arc-shaped surfaces 221. As a contact surface, the arc-shaped surface 221 provides a smoother transition when the suspension is released (the suspension stop wall 111 passes over the suspension stop protrusion 22), reducing the feeling of jamming and noise during operation, while also reducing wear on the contact surface and improving the service life of the mechanism.

[0023] In this specific embodiment, a second connecting piece 12 is connected to the first connecting piece 11, and a second rotating shaft 121 is provided on the second connecting piece 12. This provides another independent rotating connection point, allowing the entire connecting buckle to function as a modular component, which can be flexibly installed on different devices (such as lamp bodies), thus expanding its application range.

[0024] In this specific embodiment, the lower end of the latch body 2 is rolled inward to form a hook portion 28. The inwardly rolled hook portion 28 is designed to more reliably hook onto the mating lock seat, preventing accidental disengagement due to vibration or external force during the connection state, thus ensuring the stability of the connection.

[0025] In this specific embodiment, two hovering stop protrusions 22 are provided at intervals on a connecting wall 20. One of them corresponds to the hovering state when not connected, and the other corresponds to the locking position when connected, so as to ensure a more stable locking connection.

[0026] Example 2: The rest of the parts are the same as in Example 1, except that the first connecting plate 11 extends outward from both ends along the axial direction of the first rotating shaft 3 to form a suspension stop wall 111. A rotational sliding groove 311 is formed between the suspension stop wall 111 and the corresponding end of the first rotating shaft 3. The connecting wall 20 is rotatably disposed in the corresponding rotational sliding groove 311. The suspension stop protrusion 22 protrudes from the rear wall surface of the connecting wall 20 and stops by abutting against the suspension stop wall 111. High integration and clear assembly relationship: The connecting wall 20 is accommodated in the rotational sliding groove 311, forming good axial positioning, limiting the axial movement of the components, making the assembly more precise and the structure more compact. Protection and guidance: The groove structure can provide a certain degree of protection for the suspension stop protrusion 22 and other structures, while providing a more stable trajectory for the rotation process.
