Buffer structure for three-dimensional hinge

Abstract

The utility model provides a buffer structure for a three-dimensional hinge, and belongs to the technical field of hinges. The hinge solves the problems that when an existing hinge in the market is installed on a door frame and a door plate for use, the buffering effect on door closing cannot be achieved, the door closing speed cannot be reduced, serious collision is likely to happen between the door plate and the door frame when large external force is generated during door closing, and therefore the door plate and the door frame are likely to be damaged, and the service life of the door plate is prolonged. And the service life of the door plate and the door frame is influenced. The buffering structure for the three-dimensional hinge comprises a hinge body provided with a plurality of shells, a sealing plate is arranged on one side of each shell, an oil cavity is formed in the hinge body, a buffering element is arranged in an inner cavity of the oil cavity, and a through hole is formed in the buffering element. And the door plate and the door frame are prevented from being damaged due to large collision force between the door plate and the door frame.

Description

Technical Field

[0001] The utility model belongs to the technical field of hinges and relates to a buffer structure for three-dimensional hinges, in particular to a buffer structure for three-dimensional hinges. Background Art

[0002] Most traditional hinges are folding hinges, which are a special hinge design that allows doors or panels to fold 180 degrees when opened or closed. The design of folding hinges usually consists of two parts, each of which can rotate freely around the axis, allowing the door or panel to fold smoothly.

[0003] When traditional hinges on the current market are installed on door frames and door panels, they cannot play a buffering role in door closing and slow down the speed of door closing. Furthermore, when the door is closed, if a large external force is generated, serious collision is likely to occur between the door panel and the door frame, which makes the door panel and door frame easily damaged, affecting the service life of the door panel and door frame. Summary of the invention

[0004] The purpose of the utility model is to provide a buffer structure for a three-dimensional hinge in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a buffer structure for a three-dimensional hinge, characterized in that it includes a hinge body provided with a plurality of shells, a sealing plate is provided on one side of the shell, an oil chamber is opened on the hinge body, a buffer element is provided in the inner cavity of the oil chamber, and a through hole is provided on the buffer element, the buffer element includes an extrusion plate, the extrusion plate is movably connected in the oil chamber, a movable sleeve plate is sleeved on the top end of the extrusion plate, a pressure relief chamber is provided between the extrusion plate and the movable sleeve plate, a detachable handle is provided on the buffer element, and the handle is located on the outside of the sealing plate, and a pressure-bearing part is provided on the handle.

[0006] In the above-mentioned buffer structure for three-dimensional hinges, a groove one is provided on the top of the extrusion plate, and a groove two used in conjunction with the groove one is provided on the movable sleeve plate.

[0007] In the above-mentioned buffer structure for three-dimensional hinges, a spring is arranged between the buffer element and the oil chamber, and a limiting column for limiting the spring is arranged on the extrusion plate.

[0008] In the above-mentioned buffer structure for three-dimensional hinges, an elastic support rod is clamped on the inner wall of the extrusion plate, and one end of the elastic support rod is in contact with the movable sleeve plate.

[0009] In the above-mentioned buffer structure for three-dimensional hinges, an oil filling hole is provided on the shell, and an adjusting threaded rod used in conjunction with the oil filling hole is provided on the hinge body.

[0010] In the above-mentioned buffer structure for three-dimensional hinges, the spring is a T-shaped spring.

[0011] Compared with the prior art, the buffer structure for three-dimensional hinges fills the oil chamber with oil. When the door is closed, the hinge part of the hinge body squeezes the pressure-bearing part and pushes the handle to rotate, so that the handle drives the extrusion plate and the movable sleeve to rotate in the oil chamber filled with oil. When the extrusion plate and the movable sleeve rotate, the oil on both sides of the extrusion plate and the movable sleeve circulates through the pressure relief chamber, so that the oil circulation rate is slower. The oil will produce resistance to the rotation of the extrusion plate and the movable sleeve, slowing down the rotation speed, and then slowing down the door closing speed, playing a buffering role, avoiding a large collision between the door panel and the door frame, causing damage to the door panel and the door frame.

When the door is closed, the hinge part of the hinge body 1 squeezes the pressure-bearing part 12, pushing the handle 11 to rotate, so that the handle 11 drives the extrusion plate 6 and the movable sleeve plate 7 to rotate in the oil chamber 4 filled with oil. When the extrusion plate 6 and the movable sleeve plate 7 rotate, the oil on both sides of the extrusion plate 6 and the movable sleeve plate 7 circulates through the pressure relief chamber 8, so that the oil circulation rate is slow. The oil will produce resistance to the rotation of the extrusion plate 6 and the movable sleeve plate 7, slowing down the rotation speed, and then slowing down the closing speed of the door, playing a buffering role.

[0024] Preferably, a groove 9 is provided at the top of the extrusion plate 6, and a groove 2 10 used in conjunction with the groove 1 9 is provided on the movable sleeve plate 7. A through hole is formed by the overlapping portion of the groove 1 9 and the groove 2 10, and is used in conjunction with the pressure relief chamber 8 to facilitate the circulation of oil on both sides of the buffer element 5.

[0025] Preferably, a spring 13 is arranged between the buffer element 5 and the oil chamber 4, and a limiting column 17 for limiting the oil filling hole 15 is arranged on the extrusion plate 6. By setting the spring 13, the extrusion plate 6 can be pushed to rotate under the action of the spring 13 so that it can automatically reset, and the limiting column 17 can limit the oil filling hole 15.

[0026] Preferably, an elastic support rod 14 is clamped on the inner wall of the extrusion plate 6, and one end of the elastic support rod 14 is in contact with the movable sleeve plate 7. By providing the elastic support rod 14, the movable sleeve plate 7 can be supported so that the top of the movable sleeve plate 7 can better fit the inner wall of the oil chamber 4.

By adjusting the length of the adjusting threaded rod 16 in the oil chamber 4, the rotation distance of the buffer element 5 can be blocked, and then the rotation distance of the buffer element 5 can be adjusted, and after oil is added to the oil chamber 4 through the oil filling hole 15, the oil filling hole 15 can be closed by adjusting the threaded rod 16.

[0028] Preferably, the spring 13 is a T-shaped spring.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
