Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hinges, and particularly relates to a damping buffer hinge. Background Art
[0002] As is well known in the industry, the existing glass door hinges generally include a stationary leaf connected to the fixed main body of the glass door and a movable leaf fixedly connected to the movable glass door. The stationary leaf and the movable leaf are hinged by a pivot. A pivot seat is provided on the stationary leaf, and a receiving space for installing and rotating the pivot seat is provided on the movable leaf. A fixed shaft is provided inside the hinge to realize the rotational connection between the connecting members. However, the current glass door hinges do not have the function of buffering when opening and closing the door. This leads to the situation that during the closing process of the door, if relying on the inertia of the door itself, it is impossible to close the door. Even if using a hinge with a pure spring function to close the door by elastic force, the user usually needs to push one side of the door forcefully towards the door frame to move. This type of door closing method is likely to cause excessive force or a strong spring force, resulting in a too loud collision sound between the door and the door frame or a huge impact between the door and the door frame, thus affecting the safety and service life of the glass door, and the positioning after closing the door is also inaccurate. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a damping buffer hinge to solve the problems raised in the above background art.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A damping buffer hinge, comprising:
[0005] A movable clip seat plate, on the surface of which a movable clip panel is fixedly connected by screws.
[0006] A fixed clip seat plate, on the surface of which a fixed clip panel is fixedly connected by screws. A connecting plate is connected to the surface of the fixed clip seat plate. A buffer assembly for rotating with the movable clip seat plate and the movable clip panel is screwed on the surface of the connecting plate. Through the piston and the damping buffer of the buffer assembly contacting the rotating shafts inside the movable clip seat plate and the movable clip panel, the positioning concave holes on the surface of the piston and the V-shaped blocks on the surface of the damping buffer move in the convex surface and the groove on the surface of the rotating shaft, so as to buffer and make the glass door close slowly.
[0007] The convex surface and the groove are respectively a positioning convex point and a positioning concave hole. The positioning convex point is arranged on the surface of the rotating shaft, and the positioning convex point on the surface of the rotating shaft is inserted into the positioning concave hole on the surface of the piston to achieve accurate return.
[0008] Preferably, the buffer assembly includes an axle center support and a spring. One end of the axle center support is rotatably connected inside the movable clip seat plate and the movable clip panel through a rotating shaft, and bearing sleeves and gaskets are provided at the rotating parts of the two ends of the rotating shaft and the movable clip seat plate and the movable clip panel.
[0009] Preferably, two sets of threaded holes are provided on the surface of the axial center support, and the connecting plate is fixedly connected to the threaded holes on the surface of the axial center support by screws.
[0010] Preferably, two sets of mounting grooves are provided on the surface of the axial center support, and the piston and the damping buffer are respectively arranged in the two sets of mounting grooves.
[0011] Preferably, the groove includes a two-stage return surface and a one-stage return surface. The two-stage return surface and the one-stage return surface are both arranged on the surface of the rotating shaft, and the positioning bump is located at the two-stage return surface.
[0012] Preferably, both ends of the spring are respectively connected to the piston and the connecting plate.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: By fixing the fixed clamp seat plate and the fixed clamp panel, and fixing the movable clamp seat plate and the movable clamp panel to the glass door. When opening and closing the glass door, the movable clamp seat plate and the movable clamp panel rotate in the axial center support through the rotating shaft. When the rotating shaft rotates, the positioning concave hole on the surface of the piston contacts the one-stage return surface, so that the positioning concave hole moves along the one-stage return surface and approaches the two-stage return surface. During this process, the glass door can rotate quickly to perform the closing operation. When the positioning concave hole on the surface of the piston contacts the two-stage return surface, under the extrusion of the spring, while closing the glass door, the convex surface on the surface of the rotating shaft contacts the V-shaped block of the damping buffer to form a resistance. Through the mutual cooperation of the spring, the piston and the damping buffer, the glass door can be buffered when closing and close slowly until the positioning concave hole at the top of the piston is fitted with the positioning bump on the surface of the two-stage return surface of the rotating shaft, so as to realize the accurate return and the two-stage force buffer closing function, and prevent the problem that the return impact force is too large when closing the door, resulting in the collision between the door and the door frame.

[0021] The present invention provides a damping buffer hinge as shown in Figures 1-5 and includes:
[0022] A movable clamping seat plate 1, and a movable clamping panel 2 is fixedly connected to the surface of the movable clamping seat plate 1 by screws.
[0023] A fixed clamping seat plate 3, a fixed clamping panel 4 is fixedly connected to the surface of the fixed clamping seat plate 3 by screws. A connecting plate 5 is connected to the surface of the fixed clamping seat plate 3, and a buffer assembly for rotating with the movable clamping seat plate 1 and the movable clamping panel 2 is screwed to the surface of the connecting plate 5. Through the piston 6 and the damping buffer 7 of the buffer assembly, they are in contact with the rotating shaft 8 in the movable clamping seat plate 1 and the movable clamping panel 2, so that the positioning concave hole 9 on the surface of the piston 6 and the V-shaped block 10 on the surface of the damping buffer 7 move in the convex surface and the groove on the surface of the rotating shaft 8, and the buffer is carried out to make the glass door close slowly.
[0024] The convex surface and the groove are respectively a positioning convex point 901 and a positioning concave hole 9. The positioning convex point 901 is arranged on the surface of the rotating shaft 8, and the positioning convex point 901 on the surface of the rotating shaft 8 is inserted into the positioning concave hole 9 on the surface of the piston 6 to realize accurate return.
[0025] The buffer assembly includes an axle center support 11 and a spring 12. One end of the axle center support 11 is rotationally connected to the inside of the movable clamping seat plate 1 and the movable clamping panel 2 through a rotating shaft 8, and bearing sleeves 13 and gaskets 14 are provided at the rotating parts of the two ends of the rotating shaft 8 and the movable clamping seat plate 1 and the movable clamping panel 2.
[0026] Two groups of threaded holes 15 are arranged on the surface of the axle center support 11, and the connecting plate 5 is fixedly connected to the threaded holes 15 on the surface of the axle center support 11 by screws.
[0027] The surface of the axial center support 11 is provided with two groups of mounting grooves 16, and the piston 6 and the damping buffer 7 are respectively arranged in the two groups of mounting grooves 16.
[0028] The groove includes a two-stage return surface 17 and a one-stage return surface 18. The two-stage return surface 17 and the one-stage return surface 18 are both arranged on the surface of the rotating shaft 8, and the positioning bump 901 is located at the two-stage return surface 17.
