Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of this invention. The terminology used in the description of the utility model herein is only for the purpose of describing specific embodiments, and is not intended to limit the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 1 and FIG. 2 , a lifting push-pull buffer device 100 in this preferred embodiment includes a pulley frame 20 , a sliding mechanism 40 and an elastic mechanism 60 .

Wherein, the pulley frame 20 is movably connected to the sliding mechanism 40 , and the pulley frame 20 can move along a first direction relative to the sliding mechanism 40 .

The elastic mechanism 60 includes an elastic component 62 and a baffle 64 . The baffle 64 is disposed on the sliding mechanism 40 , and the elastic component 62 elastically abuts between the pulley frame 20 and the sliding mechanism 40 to provide buffer or support for the movement of the pulley frame 20 in the first direction.

Wherein, the first direction is a direction away from the pulley frame 20 and is perpendicular to the extending direction of the pulley frame 20 .

The lifting push-pull buffer device 100 is used to control the lifting and sliding of doors and windows. When the pulley frame 20 moves toward the sliding mechanism 40 in the first direction and the door and window descend, the tension of the elastic component 62 can buffer the inertial force of the door and window during the movement, avoiding the impact on the components. When the pulley frame 20 moves away from the sliding mechanism 40 in the first direction and the door and window are lifted, the rebound of the elastic element 622 can assist the door and window to be lifted, thereby achieving the purpose of labor saving.

As shown in FIG. 2 and FIG. 3 , specifically, the baffle plate 64 is provided with fixing holes 642 , and a plurality of fixing holes 642 are arranged along the length direction of the baffle plate 64 , evenly and at intervals. The elastic component 62 includes an elastic element 622 and a connecting piece 624 . The connecting member 624 includes a fixed end 6242 and a connecting end 6244 extending from the fixed end 6242 . The connecting end 6244 passes through the fixing hole 642 and cooperates with the elastic element 622 to limit the elastic element 622 .

The connecting end 6244 includes a plurality of pin shafts, the pin shafts are arranged in sequence along the length direction of the baffle plate 64 , and are arranged corresponding to the fixing holes 642 . The pin passes through the elastic element 622 and protrudes from or is accommodated in the fixing hole 642 . The fixed end 6242 is a strip structure extending along the length direction of the baffle 64 to connect multiple pins. The elastic element 622 is a spring, and the pin shaft passes through the spring to protrude or be accommodated in the fixing hole 642 .

In another embodiment, the fixed end 6242 includes a plurality of ends (as shown in FIG. 3 ), and the plurality of ends are respectively connected to a plurality of pin shafts arranged in sequence. It can be understood that the structure of the fixed end 6242 is not limited thereto, and can be set as required.

When the fixed end 6242 is pressed by the pulley frame 20 along the first direction, the spring against the fixed end 6242 is compressed to buffer the movement of the pulley frame 20 . When the pulley frame 20 moves away from the sliding mechanism 40 along the first direction, the spring can provide a force away from the baffle plate 64 , assisting the pulley frame 20 to rise, thus saving effort.

In this way, when the pulley frame 20 moves along the first direction relative to the sliding mechanism 40 , the rollers roll along the pulley frame 20 to reduce the resistance of the pulley frame 20 to move.

Please refer to FIG. 1 and FIG. 2 again, the pulley mechanism 40 includes two splints 42 and a pulley 44 . The two splints 42 are arranged in parallel and spaced apart, and the elastic mechanism 60 is arranged between the two splints 42 . Flanges 644 are arranged at intervals on both sides of the baffle plate 64 along the length direction, and the clamping plate 42 defines through-slot holes 422 matching the flanges 644 along the second direction. The flange 644 is inserted into the through-slot hole 422 to be fixed to the baffle 64 , and the baffle 64 can further fix the two splints 42 to maintain a certain distance between the two splints 42 . The pulley 44 is rotatably mounted on the clamping plates 42 and located between the two clamping plates 42 .

Wherein, the radial direction of the pulley 44 is the second direction, and the splint 42 extends along the second direction.

As shown in FIG. 5 and FIG. 6 , in another embodiment, the elastic element 622 and the fixed end 6242 of the connecting member 624 are respectively located on two sides of the baffle plate 66 .

A concave portion 426 extending along the second direction is formed on one end surface of the splint 42 perpendicular to the second direction. The recessed portion 426 includes a sliding surface and limiting surfaces (not shown) on both sides of the sliding surface for mounting the baffle 66 and enabling the baffle 66 to slide along the sliding surface in the second direction. In this way, the baffle 66 is disposed on the clamping plate 42 and can move within a certain range along the second direction. In this embodiment, the baffle 60 has a rectangular cross section.

Please refer to FIG. 1 and FIG. 5 , the lifting push-pull buffer device 100 further includes a lifting mechanism 80 . The lifting mechanism 80 is connected to the splint 42 to drive the splint 42 to move along the first direction. The lifting mechanism 80 includes a push-pull rod 82 , a connecting block 84 and a connecting pull 86 . The connecting block 84 is rotatably mounted on the pulley frame 20 and is rotatably connected to the push-pull rod 82 and the connecting lever 86 respectively.

Specifically, the push-pull rod 82 extends along the first direction, and one end thereof is rotatably connected to the connecting block 84 . One end of the connecting lever 86 is rotatably connected to the rotating block 84 , and the other end is rotatably connected to the splint 42 . When the push-pull rod 82 moves away from the splint 42 along the first direction, the connecting block 84 rotates around the joint with the pulley frame 20, driving the connecting pulley 86 to swing, so that the splint 42 moves in the second direction relative to the pulley frame 20 . It can be understood that the structure of the lifting mechanism 80 is not limited thereto, as long as it can drive the splint to move along the second direction.

The pulley frame 20 includes a connecting structure 22 and supporting structures 24 located at two ends of the connecting structure 22 . The support structure 24 defines a lift chute 242 . The lifting chute 242 gradually approaches the connecting structure 22 from one end close to the push-pull rod to the other end away from the push-pull rod. The splint 42 is fixedly connected with a pin 424 , and the lifting chute 242 is movably connected to the two splints 42 through the pin 424 . The splint 42 drives the pin 424 to move along the first direction, so that the lifting chute 242 drives the pulley frame 20 to move along the first direction.

The connecting structure 22 defines a pulley groove 222 for partially accommodating the pulley 44 . When the pulley frame 20 is not lifted, the pulley 44 is partially accommodated in the pulley groove 222 to prevent the pulley 44 from moving relative to the pulley frame 20 . After the pulley frame 20 is lifted along the first direction, the pulley 44 leaves the pulley groove 222 , so that the pulley frame 20 and the splint 42 can move relatively along the first direction.

The working principle of the above-mentioned lifting push-pull buffer device 100 is as follows:

When the sliding door is in the rising state, the push-pull rod rises, and the connecting block drives the connecting lever to swing. The swinging of the lever moves the splint 42 in the second direction. The pin 424 on the splint 42 moves in a second direction relative to the lift chute 242 on the pulley frame 20 , and the lift chute 242 moves the pulley frame 20 away from the splint 42 in a first direction. Pulley 44 leaves the pulley 44 grooves that offer on the carriage. When the pin 424 moves to the end of the lift chute 242, it is positioned at this position, and the sliding door can be pushed and pulled freely. During the rising process of the sliding door, the elastic element 622 in the elastic mechanism 60 provides a rising thrust for the pulley frame 20 to achieve the purpose of labor saving.

When the sliding door is in the descending state, the push-pull rod descends, and the splint 42 moves along the second direction through the connecting block and the connecting pull. The pin shaft cooperates with the lifting chute 242 to make the pulley frame 20 move along the first direction close to the splint 42 and return to the initial position. During the sliding door's descending process, the elastic element 622 in the elastic mechanism 60 provides buffer for the falling of the pulley frame 20, avoiding the impact on the parts due to the heavy weight of the sliding door.

During the relative movement between the above-mentioned lifting push-pull buffer device 100 and the sliding mechanism 40 and the pulley frame 20, the elastic mechanism 60 is used to restrain the relative movement between the sliding mechanism 40 and the pulley frame 20 in the first direction, and promote the movement between the sliding mechanism 40 and the pulley frame. 20 relative to each other in the first direction to avoid the impact on the parts caused by the rapid drop of the sliding door, which will affect the life of the parts. And when lifting the sliding door, utilize the springback of the elastic element 622 in the elastic mechanism 60 to assist the sliding door to lift, so as to achieve the purpose of labor saving, and avoid the handle connected to the push-pull lifting buffer device 100 from being subjected to a large force, which affects the service life.

A sliding door, comprising a door frame, a door leaf, a transmission structure and the lifting and sliding buffer device 100 mentioned above. The lifting push-pull buffer device 100 is installed in the transmission structure. When the sliding door needs to be slid, the door leaf rises, and the lifting push-pull buffer device 100 provides support force for the door leaf to achieve the purpose of labor saving. When the sliding door is fixed, when the door leaf falls, the lifting push-pull buffer device 100 provides a buffer for the door leaf, so as to prevent the falling of the door leaf from causing impact on other parts.

In this way, the above-mentioned sliding door has a long service life, the parts are not easy to be damaged, and the operation process is convenient and labor-saving.
