Detailed Implementation
[0038] like Figures 1 to 20 As shown, a multi-functional hinge includes a mounting base plate 10 on which a mounting valve body 20 is mounted. A movable component 30 is installed inside the mounting valve body 20. A first pressure plate 40 is provided on one side of the mounting valve body 20, and a second pressure plate 50 is provided on the other side. The first pressure plate 40 is connected to the movable component 30, and the second pressure plate 50 is connected to the first pressure plate 40. In use, the mounting base plate 10 is fixed to the door frame by fasteners. The mounting valve body 20 and the first pressure plate 40 are connected to... The second pressure plate 50 works in concert with the first pressure plate 40 and the second pressure plate 50 to clamp the glass door panel when the door is closed, ensuring that the door is stable and does not shift. When the door is opened or closed, the movable component 30 provides a buffering force to control the opening and closing speed of the door, preventing the door from hitting the door frame or generating excessive impact. The movable component 30 plays a buffering role, reducing violent collisions when the door is closed, making the opening and closing process of the door smoother and quieter. At the same time, when the door is opened, the movable component 30 can also provide appropriate relief, so that the door will not open suddenly and quickly.
[0039] In the specific implementation, the movable assembly 30 comprises a rotating shaft 31, the side of which is sequentially provided with a buffer connecting part 311, a sliding connecting part 312 and a positioning connecting part 313. The lower part of the buffer connecting part 311 is connected with a spring sleeve 32, the middle part of the spring sleeve 32 is connected with a buffer spring 33, the bottom of the buffer spring 33 abuts against the mounting bottom plate 10. The outer side of the sliding connecting part 312 is connected with a sliding block 34, the outer side wall of the sliding connecting part 312 is concavely provided with a helical sliding screw groove 312a, the inner side of the sliding block 34 is connected with a sliding protrusion 341, the sliding protrusion 341 is movably connected in the sliding screw groove 312a, the lower side of the sliding block 34 is concavely provided with a buffer recess 342, the buffer recess 342 is connected with a buffer 35, the lower part of the positioning connecting part 313 is connected with a zero-degree lock block 36, the upper two sides of the zero-degree lock block 36 are symmetrically provided with positioning rollers 361, the two positioning rollers 361 are positioned and connected with the positioning connecting part 313, the middle part of the zero-degree lock block 36 is provided with a buffer slot 362, the buffer 35 is connected in the buffer slot 362, the lower two sides of the zero-degree lock block 36 are symmetrically connected with lock block spring rubbers 363, the two lock block spring rubbers 363 abut against the mounting bottom plate 10. The opening process: when the door is opened, the rotating shaft 31 drives the movable assembly 30 to move, the buffer connecting part 311 compresses the buffer spring 33, the elastic force of the buffer spring 33 provides a smooth opening process, when the door is opened to 90°, the sliding screw groove 312a of the sliding connecting part 312 drives the sliding block 34 and the sliding protrusion 341, thereby driving the opening of the buffer 35. At this time, the buffer spring 33 releases the stored energy to assist the smooth opening of the door. When the door is opened to 90°, the rotating shaft crank structure plane of the buffer connecting part 311 is pressed and combined with the plane of the spring sleeve 32, the buffer spring 33 provides power to realize the positioning of the door opening to 90°. The closing process: when the door is closed, the rotating shaft 31 drives the rotating shaft crank structure of the buffer connecting part 311 to compress the buffer spring 33, the buffer spring 33 provides mechanical support to automatically close the door. The sliding screw groove 312a of the sliding connecting part 312 drives the sliding block 34 and the sliding protrusion 341 to compress the buffer 35, thereby realizing the buffer closing effect and avoiding the impact of the door. When the door is closed to about 10°, the zero-degree lock block 36 is driven by the lock block spring rubbers 363, the positioning rollers 361 are matched with the positioning connecting part 313 to position the door at the angle. When the door is opened to 90°, the positioning rollers 361 of the zero-degree lock block 36 are intervened in the 90° opening positioning by the lock block spring rubbers 363 to ensure that the door remains at the 90° angle. The design provides a smooth, accurate and adjustable opening and closing system through the precise cooperation of the components.Particularly in the impact-prone door body such as glass door, the design of the buffer spring 33 and the buffer 35 effectively reduces the vibration and impact of the door, while the positioning system ensures the accurate positioning and stability of the door when opening and closing. In addition, through the design of the sliding screw groove 312a and the sliding block 34, the opening and closing process of the door is smoothly controlled, realizing multiple functions such as buffering, shock absorption, positioning, etc., which is suitable for door systems requiring high precision and stability.
[0040] In use, the front group spring force ensures a large-angle slow closing of the door during the closing process. The cooperation of the buffer spring 33 and the buffer 35 can provide gentle mechanical support in the initial stage of door closing, so that the door avoids rapid collision when closing at a large angle. When the door starts to close, the rotating shaft rod 31 drives the movable assembly 30, and the buffer connecting part 311 starts to compress the buffer spring 33. Because the elastic force of the buffer spring 33 is relatively soft, the door will not be too violent when closing. The elastic force it provides can effectively alleviate the impact force when the door is closed, ensuring that the door closing action is stable and quiet. Cooperating with the buffer 35: when the door is closed to a larger angle (for example, close to 90°), the buffer 35 plays a role, further alleviating the movement of the door, avoiding the door from closing too fast or too violently. The design of the buffer makes the closing process of the door more gentle, especially when closing to the closed state, the action of the door becomes very soft, thereby effectively reducing the impact and vibration. The role of the rear group spring force is to ensure that the door provides stronger force when closing to the completely closed state to realize accurate zero-degree positioning. When the door is close to completely closed, especially when closing to about 10°, the spring system of the rear group starts to play a stronger role. The lock block spring rubber 363 drives the positioning function of the zero-degree lock block 36, ensuring that the door is accurately stopped when closing. At this time, the zero-degree lock block 36 accurately locks the door at the zero-degree position (completely closed state) through cooperation with the positioning roller 361, avoiding the door from opening again due to external force or vibration. When the door is closed to about the last 5 degrees, the role of the zero-degree lock block 36 is particularly prominent. The strong force provided by the lock block spring rubber 363 ensures that the door can quickly enter the locked state in the last stage, avoiding the door staying in an unstable intermediate position, thereby realizing strong and accurate zero-degree positioning. This process ensures the stability of the closed door through the cooperation of the zero-degree lock block 36 and the positioning roller 361. The role of the front group spring: provide a slow and stable closing process to avoid sudden closing of the door or generate excessive impact, especially when the door is close to completely closed, the buffer spring 33 and the buffer 35 together ensure that the closing action is not too fast or too violent. The role of the rear group spring: provide the last strong support in the closing process to ensure that the door can accurately and quickly enter the locked state when closing to the last 5 degrees, avoiding unstable conditions when closing.
