Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] The following combination Figures 1 to 5 The present invention describes a buffer assembly and a buffer hinge.

[0036] like Figures 1 to 4As shown, the utility model provides a buffer assembly, including a first sleeve 1, a second sleeve 2, an elastic member 3, a transmission column 4, a guide column 5 and a damper 6. The outer wall of the first sleeve 1 is provided with a rotation guide groove 11, and the rotation guide groove 11 is spirally arranged around the outer wall of the first sleeve 1; the second sleeve 2 can rotate relative to the first sleeve 1; the elastic member 3 is provided on the second sleeve 2; the transmission column 4 is connected to the second sleeve 2 through the elastic member 3 and can move along the axial direction of the second sleeve 2; the guide column 5 is connected to the transmission column 4, and both ends of the guide column 5 extend along the radial direction of the transmission column 4 and are inserted into the rotation guide groove 11; the damper 6 is provided on the first sleeve 1, and the movable shaft of the damper 6 abuts against the transmission column 4.

[0037] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 As shown, specifically, the first sleeve 1 is located on the upper side of the second sleeve 2 .

[0038] In the buffer assembly provided in this embodiment, the first sleeve 1 and the second sleeve 2 are mainly used to connect the two connecting parts of the hinge. The first sleeve 1 and the second sleeve 2 can realize the rotation function of the entire hinge by rotating with each other. Since the first sleeve 1 is provided with a spirally arranged rotation guide groove 11, and the second sleeve 2 is provided with a transmission column 4 and a guide column 5, when the second sleeve 2 is rotated, the guide column 5 will move along the rotation guide groove 11, thereby driving the transmission column 4 to rotate and move. Specifically, in the process of the hinge from closing to opening, the second sleeve 2 is rotated, the guide column 5 will move along the rotation guide groove 11, and while rotating, it will drive the transmission column 4 to move in the direction of the elastic member 3. At this time, the elastic member 3 will be in a compressed state, and the hinge will be opened and closed. In the process, the second sleeve 2 is rotated, and the guide column 5 moves along the rotating guide groove 11. While rotating, it will drive the transmission column 4 to move in the direction of the first sleeve 1, and the elastic member 3 will release its own elastic potential energy, pushing the transmission column 4 to move in the direction of the first sleeve. The transmission column 4 drives the movable shaft of the damper 6 to move, and the damper 6 can offset part of the elastic potential energy of the elastic member 3, so that the transmission column 4 can slide slowly, thereby achieving a buffering effect. Compared with the existing hydraulic buffer mechanism, the overall structure of the buffer assembly of the utility model is simpler, and there is no need to consider the oil circuit problem. Buffering can be achieved using a simple mechanical mechanism, which is not easy to damage and has a longer service life. It can also better adapt to different door leaves, has better adaptability, and is more convenient to use.

[0039] In this embodiment, the elastic member 3 is a spring, which can provide a stable elastic force. In some embodiments, the elastic member 3 can also be an elastic part such as a spring or a rubber block.

[0040] In some embodiments, the rotation guide groove 11 includes a spiral section 111 and a horizontal section 112. The spiral section 111 is spirally arranged around the outer wall of the first sleeve 1, and the horizontal section 112 is arranged around the outer wall of the first sleeve 1 along the circumference of the first sleeve 1. The projection of the spiral section 111 along the axial direction of the first sleeve 1 is a quarter arc, and the projection of the horizontal section 112 along the axial direction of the first sleeve 1 is a quarter arc.

[0041] Specifically, by providing the spiral section 111, the guide column 5 and the transmission column 4 can be moved up and down while rotating. In the process of the hinge from closing to opening, the transmission column 4 will move downward while rotating. At this time, the elastic member 3 will be in a compressed state. If the horizontal section 112 is not provided, after rotation, the elastic force of the elastic member 3 will immediately move the transmission column 4 upward. At this time, the hinge cannot remain in the open state, that is, the door and window cannot remain in the open state, which is inconvenient to use. By providing the horizontal section 112 parallel to the horizontal plane, the guide column 5 can enter from the inclined spiral section 111 to In the horizontal section 112, the guide column 5 cannot move up and down, that is, the transmission column 4 cannot move up and down. Therefore, the elastic force of the elastic member 3 cannot drive the transmission column 4 to move upward. The hinge can remain in the open state, that is, the doors and windows can remain in the open state. When the hinge needs to be closed, the doors and windows can be pushed by hand to make the second sleeve 2 drive the guide column 5 to rotate, and the guide column 5 can enter the spiral section 111 from the horizontal section 112. The elastic force of the elastic member 3 can now push the rotating shaft core to move upward. At this time, manual pushing is no longer required, and the doors and windows can be closed, which is more convenient to use.

[0042] In some embodiments, there are two rotating guide grooves 11, and both ends of the guide column 5 extend radially along the transmission column 4 and are respectively inserted into the two rotating guide grooves 11. The two rotating guide grooves 11 are centrally symmetrically arranged about the axis of the first sleeve 1, and the guiding effect is better.

[0043] In some embodiments, the second sleeve 2 is provided with a connecting portion 21, which is inserted into the first sleeve 1. The outer wall of the connecting portion 21 is provided with an avoidance hole 211 for the guide column 5 to pass through. By providing the connecting portion 21, the second sleeve 2 can maintain a relative rotation state relative to the first sleeve 1 without separation. By providing the avoidance hole 211, when the second sleeve 2 rotates, it can drive the guide column 5 to rotate, thereby driving the transmission column 4 to rotate, and the rotation is smoother.

[0044] Specifically, the second sleeve 2 is further provided with a connecting portion 22, which is threadedly connected to the upper end of the second sleeve 2, and the connecting portion 21 is connected to the connecting portion 22. The connecting portion 21 is installed on the second sleeve 2 through the connecting portion 22, which is very convenient for both disassembly and installation.

[0045] In some embodiments, the buffer assembly also includes a first adjusting member 7, which is threadedly connected to the first sleeve 1 and can abut against the end of the damper 6 away from the second sleeve 2. When the damping force of the damper 6 needs to be adjusted, the first adjusting member 7 can be screwed with a tool to change the position of the first adjusting member 7 in the first sleeve 1, so as to adjust the position of the damper 6 and thus adjust the damping force of the damper 6, which is more convenient to adjust.

[0046] In some embodiments, a hexagonal hole is provided at one end of the first adjusting member 7 away from the second sleeve 2 , which makes adjustment more convenient.

[0047] In some embodiments, the buffer assembly also includes a second adjusting member 8, which is threadedly connected to the second sleeve 2 and can abut against the end of the elastic member 3 away from the first sleeve 1. When the elastic strength of the spring needs to be adjusted, the second adjusting member 8 can be screwed with a tool to change the position of the second adjusting member 8 in the second sleeve 2, so as to adjust the compression amplitude of the elastic member 3, thereby adjusting the pushing force of the elastic member 3 on the rotating shaft core, that is, adjusting the force and speed when the hinge is closed, which is more convenient to adjust.

[0048] In some embodiments, a hexagonal hole is provided at the end of the second adjusting member 8 away from the first sleeve 1 , which makes adjustment more convenient.

[0049] like Figure 5 As shown, the utility model also provides a buffer hinge, including a first connecting member 9, a second connecting member 10 and the above-mentioned buffer assembly, the first connecting member 9 has a first fixed portion 91 and a first rotating portion 92, the first fixed portion 91 is connected to the first sleeve 1 and cannot rotate relative to the first sleeve 1, the first rotating portion 92 is rotatably connected to the second sleeve 2, the second connecting member 10 has a second fixed portion 101 and a second rotating portion 102, the second fixed portion 101 is connected to the second sleeve 2 and cannot rotate relative to the second sleeve 2, the second rotating portion 102 is rotatably connected to the first sleeve 1.

[0050] In the buffer hinge provided by the present invention, the above-mentioned buffer assembly is adopted, which can provide a good buffering effect for the mutual rotation between the first connecting member 9 and the second connecting member 10, with better buffering effect, better applicability, and more convenient use.

[0051] In some embodiments, the buffer hinge further includes a plurality of bearing rings, which are spaced apart between the first connecting member 9 and the second connecting member 10. The plurality of bearing rings are all sleeved on the first sleeve 1 and the second sleeve 2, making the rotation smoother.
