[0043] The guide groove 1 is fixedly installed on the top of the door frame, and the guide wheel 2 on the top of the balanced door is installed in the guide groove 1. When the balanced door rotates, the guide wheel 2 moves in the guide groove 1.

[0044] One end of the elastic component 3 is fixedly mounted on one end of the guide groove 1, and the other end of the elastic component 3 is located in the guide groove 1. The guide wheel 2 moves in the guide groove 1 and abuts against the elastic component 3. When the balancing door loses power, the elastic component 3 pushes the guide wheel 2 to reset.

[0045] The bottom plate 4 is fixedly mounted on the guide groove 1 . The bottom plate 4 is located at the top of the guide groove 1 and outside the guide groove 1 .

[0046] The sliding groove 5 is slidably mounted on the bottom plate 4 , and the sliding groove 5 slides along the length direction of the bottom plate 4 .

[0047] One end of the connecting shaft 6 is fixedly mounted on the elastic component 3, and the other end passes through the base plate 4 and the guide groove 1 and is fixedly mounted on the sliding groove 5. The connecting shaft 6 moves along the axial direction of the guide groove 1 with the elastic component 3, thereby driving the sliding groove 5 to move on the base plate 4.

[0048] The fixed shell 7 is fixedly mounted on the guide groove 1 , and the fixed shell 7 covers the outside of the bottom plate 4 and the sliding groove 5 , and the sliding groove 5 is sliding in the fixed shell 7 .

[0049] One end of the bracket 8 is rotatably mounted on one end of the fixed shell 7 close to the elastic component 3 , and the other end of the bracket 8 extends toward the other end of the fixed shell 7 .

[0050] One end of the positioning pin 9 is installed at the other end of the bracket 8. When the door is stopped, the other end of the positioning pin 9 passes through the sliding groove 5 and the bottom plate 4 and extends into the guide groove 1 to abut against the guide wheel 2. The guide wheel 2 is located between the positioning pin 9 and the elastic component 3. When the bracket 8 rotates, the positioning pin 9 moves up and down with the bracket 8.

[0051] The rebound device 10 is installed on the inner wall of one side of the fixed shell 7. The telescopic end of the rebound device 10 is connected to the end of the sliding groove 5 close to the positioning pin 9. When the rebound device 10 bounces open, it pushes the sliding groove 5 to move. The rebound device 10 can use the rebound device 10 of the heavy-type rebounder model produced by Guangzhou Lingu Hardware Co., Ltd.

[0052] Through the above structure, the upper balanced door stopping device provided by the present invention is installed on the top of the balanced door, and the guide wheel 2 of the balanced door is installed in the guide groove 1. When the door is opened, the guide wheel 2 moves axially in the guide groove 1. When the guide wheel 2 passes under the positioning pin 9, the guide wheel 2 squeezes the elastic component 3, and the elastic component 3 drives the connecting shaft 6 to move in the direction away from the elastic component 3, thereby driving the sliding groove 5 to move. At this time, the rebound device 10 at one end of the sliding groove 5 away from the elastic component 3 pops open, so that the sliding groove 5 moves along the end of the bottom plate 4 close to the rebound device 10, so that the end of the bracket 8 close to the positioning pin 9 rotates in the direction of the guide groove 1, so that the positioning pin 9 passes through the bottom plate 4 and extends into the guide groove 1, so that the guide wheel 2 is located between the rebound component and the positioning pin 9, so that the balanced door stops and the balanced door cannot be closed automatically; when the door needs to be closed, the guide wheel 2 squeezes the elastic component 3, and the connecting shaft 6 drives the sliding groove 5 to move toward the end of the bottom plate 4 away from the rebound device 10, so that the bracket 8 drives the positioning pin 9 to slide upward from the guide groove 1, so that the guide wheel 2 passes from the bottom of the positioning pin 9, and the balanced door is closed. Therefore, the upper balanced door stopping device is more convenient for stopping the balanced door after the door is opened.

[0053] An optional implementation of this embodiment is as follows: the elastic component 3 includes a stopper 31, a first spring 32 and a pressing block 33, wherein:

[0054] The stopper 31 is installed at one end of the guide groove 1 , and the stopper 31 is located at an end away from the rebound device 10 .

[0055] One end of the first spring 32 is mounted on the stopper 31 , and the other end extends toward an end away from the stopper 31 . The first spring 32 is located in the guide groove 1 , and is a compression spring.

[0056] The pressure block 33 is installed at one end of the first spring 32 away from the stop block 31. When the door is stopped, the guide wheel 2 abuts against the pressure block 33, and the guide wheel 2 pushes the pressure block 33 to move in the guide groove 1. One end of the connecting shaft 6 is fixedly installed on the pressure block 33. After the balanced door loses thrust, the first spring 32 resets and pushes the pressure block 33 to move.

[0057] An optional implementation of this embodiment is as follows: a groove adapted to the guide wheel 2 is provided on the surface of the pressure block 33 abutting against the guide wheel 2, so that the contact area between the guide wheel 2 and the pressure block 33 is larger, so that the pressure block 33 has a better pushing effect on the guide wheel 2.

[0058] An optional implementation of this embodiment is as follows: it also includes a second spring 11, one end of the second spring 11 is installed on the bracket 8, and the other end is fixedly connected to the top wall of the fixed shell 7. The second spring 11 is located in the fixed shell 7, and the second spring 11 is used to make the bracket 8 abut against the positioning pin 9 so that the positioning pin 9 moves up and down with the bracket 8.

[0059] An optional implementation of this embodiment is as follows: it also includes a positioning pin 9 sleeve, which is installed on the fixed shell 7, and the positioning pin 9 sleeve is arranged outside the positioning pin 9. The positioning pin 9 sleeve is used to guide the positioning pin 9, and an opening is opened on the positioning pin 9 sleeve to pass through the bracket 8.

[0060] An optional implementation of this embodiment is as follows: it also includes an axle pin 13, which is installed on the sliding groove 5, and the bottom end of the bracket 8 abuts against the axle pin 13. When the sliding groove 5 slides, the bracket 8 abuts against the axle pin 13, thereby causing the bracket 8 to rotate.

[0061] An optional implementation of this embodiment is as follows: it also includes a roller 12, which is sleeved outside the axle pin 13, and the bottom end of the bracket 8 abuts against the roller 12. The roller 12 is used to reduce the friction between the bracket 8 and the axle pin 13 so that the bracket 8 can rotate better.

[0062] An optional implementation of this embodiment is as follows: a waist-shaped groove 14 is provided on the sliding groove 5, the bottom plate 4 and the guide groove 1, and the connecting shaft 6 and the positioning pin 9 are located in the waist-shaped groove 14. When the sliding groove 5 slides, the connecting shaft 6 and the positioning pin 9 are in the waist-shaped groove 14 to reduce the obstruction of the sliding groove 5 by the connecting shaft 6 and the positioning pin 9. Planes adapted to the waist-shaped groove 14 are provided on both sides of the positioning pin 9 sleeve to make the contact area between the positioning pin 9 sleeve and the waist-shaped groove 14 larger, so that the positioning pin 9 sleeve can move better in the waist-shaped groove 14.

[0063] In summary, the upper balanced door stop device is installed on the top of the balanced door, and the guide wheel 2 of the balanced door is installed in the guide groove 1. When the door is opened, the guide wheel 2 moves in the guide groove 1 along the axial direction of the guide groove 1. When the guide wheel 2 passes under the positioning pin 9, the guide wheel 2 squeezes the pressing block 33, and the pressing block 33 drives the connecting shaft 6 to move in the direction away from the elastic component 3, thereby driving the sliding groove 5 to move. At this time, the rebound device 10 at one end of the sliding groove 5 away from the elastic component 3 is rebounded, so that the sliding groove 5 moves along the end of the bottom plate 4 close to the rebound device 10. When the sliding groove 5 slides, the second spring 11 makes the bracket 8 abut against the roller 12, so that the bracket 8 is close to the positioning pin 9. One end of the pin 9 rotates toward the guide groove 1, so that the positioning pin 9 in the positioning pin 9 sleeve passes through the bottom plate 4 and extends into the guide groove 1, so that the guide wheel 2 is located between the rebound component and the positioning pin 9, so that the balanced door stops and the balanced door cannot be closed automatically; when the door needs to be closed, the guide wheel 2 squeezes the elastic component 3, and the connecting shaft 6 drives the sliding groove 5 to move toward the end of the bottom plate 4 away from the rebound device 10, so that the bracket 8 drives the positioning pin 9 to slide upward from the guide groove 1, so that the guide wheel 2 passes from the bottom of the positioning pin 9 to close the balanced door. Therefore, the upper balanced door stopping device is more convenient for stopping the balanced door after opening the door.
