Description

Technical Field

[0001] The present invention relates to a sliding door system accessory, specifically an elastic adjustable stopper for a sliding door system. Background Art

[0002] A stopper is a common accessory for a sliding door system. It is usually fixed inside a sliding door guide rail. A pulley assembly is slidably installed inside the sliding door guide rail, and the sliding door is connected through the pulley assembly. When the sliding door moves, the pulley assembly moves along the sliding door guide rail. The stopper is used to stop the sliding door that has moved into place, thereby closing the sliding door. Currently, the stoppers of sliding door systems on the market have a single function and only have a one-way stopping function. When the sliding door moves at a relatively high speed, the sliding door is likely to bounce open when hitting the stopper, resulting in a gap between the sliding door and the door frame and unable to fully close the sliding door. In addition, after such a stopper is installed, the sliding door is very easy to open. Especially when the sliding door guide rail is not installed horizontally, the sliding door may even open automatically, affecting the use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an elastic adjustable stopper for a sliding door system that combines a stopping function and a damping function and whose damping force can be adjusted, aiming at the deficiencies of the prior art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows: An elastic adjustable stopper for a sliding door system includes a stopper body and an elastic member made of an elastic material. One side of the elastic member is adjustably installed on the stopper body in a vertical direction. The other side of the elastic member is suspended outside the stopper body. The bottom surface of the other side of the elastic member includes an intersecting plane and an inclined plane, and the inclined plane slopes upward from one side edge of the plane. After installation, the stopper body is fixed inside the sliding door guide rail. There is a gap between the plane and the bottom wall of the sliding door guide rail. A pulley assembly is slidably installed inside the sliding door guide rail. The inclined plane faces the pulley assembly. The pulley assembly is used to connect the sliding door. The pulley assembly includes a pulley mounting seat and several pulleys installed on the pulley mounting seat. The height of the gap is adapted to the height of the pulley mounting seat, and the gap is used to clamp the pulley mounting seat when the sliding door is closed.

[0005] The elastic adjustable stopper for the sliding door system of the present invention has both a stopping function and a damping function. After installation, the pulley assembly moves driven by the sliding door. The pulley mounting seat is clamped into the gap between the lower plane of the elastic member and the bottom wall of the sliding door guide rail through the lower inclined plane of the elastic member. Under the action of the elastic force of the elastic member, the upper surface of the pulley mounting seat is pressed tightly to generate a damping force, thereby suppressing the rebound or accidental forced opening of the sliding door and ensuring the use effect of the sliding door. The vertical position of the elastic member on the stopper body is adjustable, so that the interference amount and elastic force of the contact between the lower plane of the elastic member and the upper surface of the pulley mounting seat can be adjusted accordingly, and the damping force of the sliding door during closing and opening can be adjusted.

[0006] Preferably, an adjusting screw is arranged in the stopper body from bottom to top. The adjusting screw passes through the stopper body and is threadedly connected with the elastic member. The screw head of the adjusting screw presses the stopper body upward. Further, the adjusting screw includes a screw head, a smooth rod and a threaded rod which are integrally arranged in sequence. The smooth rod passes through the stopper body. The threaded rod is threadedly connected with the elastic member. A ring groove is arranged at the connection of the smooth rod and the threaded rod. An E-shaped snap ring is buckled at the ring groove. An insert nut is embedded in the elastic member. The threaded rod is threadedly connected with the insert nut. The E-shaped snap ring is used to limit the axial freedom degree of the adjusting screw. By rotating the adjusting screw, the lifting of the elastic member can be realized, and the interference amount and elastic force of the contact between the lower plane of the elastic member and the upper surface of the pulley mounting seat can be adjusted, and the operation is convenient.

[0007] Preferably, a groove is arranged on the upper side of the stopper body. One side of the elastic member is embedded in the groove. The front side and the rear side of the elastic member are respectively matched and positioned with the front side and the rear side of the groove. The groove can play a good role in front-back positioning of the elastic member, limit the front-back freedom degree of the elastic member, and is beneficial to improving the compactness of the overall structure of the stopper.

[0008] Preferably, the elastic member is an elastic member made of elastic plastic. A hollow hole is arranged in the elastic member. The hollow hole is located above the plane and the inclined plane. The elastic member can be selected from elastic plastics with good toughness, such as PP. The hollow hole plays a buffering role, which is beneficial to increasing the elasticity of the elastic member, making it easy for the pulley mounting seat to be clamped into the gap between the lower plane of the elastic member and the bottom wall of the sliding door guide rail, and ensuring the pressing effect on the pulley mounting seat.

[0009] Preferably, a locking screw is inserted through the stopper body from bottom to top. The locking screw is threadedly connected to the stopper body and is used to upwardly press against the top wall of the sliding door guide rail. A hexagonal nut is threadedly connected to the outside of the locking screw, and the hexagonal nut downwardly presses against the stopper body. When the locking screw is rotated until it upwardly presses against the top wall of the sliding door guide rail, the locking screw pulls the hexagonal nut, causing the hexagonal nut to downwardly press against the stopper body, thus completing the fixation of the stopper body within the sliding door guide rail. By upwardly pressing the top wall of the sliding door guide rail with the locking screw to fix the position of the stopper body within the sliding door guide rail, the structure is simple and it is easy to adjust the position of the stopper body in the length direction of the sliding door guide rail.

[0010] Further, the front side and the rear side of the stopper body are respectively in positioning cooperation with the front side wall and the rear side wall of the sliding door guide rail, and the bottom surface of the stopper body is in positioning cooperation with the bottom wall of the sliding door guide rail.

[0011] Preferably, an elastic rubber rod is fixed to one side of the stopper body facing the pulley assembly, and the elastic rubber rod is located below the plane. While the pulley mounting seat is snapped into the gap between the lower plane of the elastic member and the bottom wall of the sliding door guide rail, the elastic rubber rod can perform a buffering and stopping function to prevent the pulley mounting seat from continuing to move forward, ensuring the reliability of stopping the sliding door.

[0012] Preferably, the sliding door guide rail is an aluminum alloy guide rail or a sheet metal bending guide rail. Further, a plurality of downwardly concave reinforcing ribs are provided on the top wall of the sliding door guide rail, and each reinforcing rib is arranged along the length direction of the sliding door guide rail. The downwardly concave reinforcing ribs on the top of the sliding door guide rail can enhance the overall rigidity of the sliding door guide rail.

[0013] Compared with the prior art, the present invention has the following advantages: The elastic adjustable stopper for the sliding door system of the present invention has both a stopping function and a damping function, can adjust the magnitude of the damping force for closing and opening the sliding door, ensure the use effect of the sliding door, achieve reliable stopping of the sliding door and ensure that the sliding door is completely closed, and the sliding door will not rebound and open when it hits the stopper. At the same time, a certain damping force needs to be overcome to open the sliding door, which is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

After installation, the stopper body 1 is fixed in the sliding door guide rail 3. There is a gap 24 between the plane 21 and the bottom wall of the sliding door guide rail 3. A pulley assembly 4 is slidably installed in the sliding door guide rail 3. The inclined surface 22 faces the pulley assembly 4. The pulley assembly 4 is used to connect a sliding door (not shown in the figure). The pulley assembly 4 includes a pulley mounting seat 41 and a plurality of pulleys 42 installed on the pulley mounting seat 41. The height of the gap 24 is adapted to the height of the pulley mounting seat 41. The gap 24 is used to clamp the pulley mounting seat 41 when the sliding door is closed. In this embodiment, the pulley assembly 4 can be a two-wheel, three-wheel or four-wheel pulley assembly 4.

[0023] In this embodiment, an adjusting screw 5 is inserted through the stopper body 1 from bottom to top. The adjusting screw 5 passes through the stopper body 1 and is threadedly connected to the elastic member 2. The screw head 51 of the adjusting screw 5 presses the stopper body 1 upward. Specifically, the adjusting screw 5 includes a screw head 51, a smooth rod 52 and a threaded rod 53 which are integrally arranged in sequence. The smooth rod 52 passes through the stopper body 1, and the threaded rod 53 is threadedly connected to the elastic member 2. A ring groove 54 is provided at the connection between the smooth rod 52 and the threaded rod 53. An E-shaped snap ring 55 is buckled at the ring groove 54. An insert nut 56 is embedded in the elastic member 2, and the threaded rod 53 is threadedly connected to the insert nut 56. A groove 11 is provided on the upper side of the stopper body 1. One side of the elastic member 2 is embedded in the groove 11, and the front side and the rear side of the elastic member 2 are respectively matched and positioned with the front side and the rear side of the groove 11.

[0024] In this embodiment, a locking screw 6 is inserted through the stopper body 1 from bottom to top. The locking screw 6 is threadedly connected to the stopper body 1 and is used to tightly press against the top wall of the sliding door guide rail 3 upward. A hexagonal nut 61 is threadedly connected to the outer side of the locking screw 6, and the hexagonal nut 61 tightly presses the stopper body 1 downward; the front side and the rear side of the stopper body 1 are respectively positioned in cooperation with the front side wall and the rear side wall of the sliding door guide rail 3, and the bottom surface of the stopper body 1 is positioned in cooperation with the bottom wall of the sliding door guide rail 3.

[0025] In this embodiment, an elastic rubber rod 7 is fixed to one side of the stopper body 1 facing the pulley assembly 4. The elastic rubber rod 7 is located below the plane 21.

The locking screw 6 tightens the hexagonal nut 61, causing the hexagonal nut 61 to tightly press the stopper body 1 downward, completing the fixation of the stopper body 1 in the sliding door guide rail 3. During the installation process, by rotating the adjusting screw 5, the lifting of the elastic member 2 can be realized, and thus the interference amount and the elastic force of the lower plane 21 of the elastic member 2 in contact with the upper surface of the pulley mounting seat 41 can be adjusted, realizing the adjustment of the damping force size when the sliding door is closed and opened. After installation, the pulley assembly 4 moves under the drive of the sliding door. The pulley mounting seat 41 is caught in the gap 24 between the lower plane 21 of the elastic member 2 and the bottom wall of the sliding door guide rail 3 via the lower inclined surface 22 of the elastic member 2. Under the action of the elastic force of the elastic member 2, the upper surface of the pulley mounting seat 41 is tightly pressed to generate a damping force, thereby suppressing the rebound or accidental forced opening of the sliding door and ensuring the use effect of the sliding door.
