Description

Technical Field

[0001] The invention belongs to the field of sliding door buffers, and in particular relates to a bidirectional sliding door buffer for embedded sliding doors. Background Art

[0002] Embedded sliding door, also known as "pocket door", is a design that embeds the door body into the wall, so that the door body is completely hidden in the wall when closed, which has the advantages of beauty and space saving. When opening or closing the traditional sliding door, under the action of inertia, the door body usually hits the wall, making a "snap" sound or pinching the hand. To address this problem, traditionally, a two-way sliding door buffer is usually installed on the sliding door. The traditional two-way sliding door buffer structure, as shown in the Chinese utility patent with the authorization announcement number "CN215408058 U" and the name "A two-way sliding door buffer and a movable door frame", includes: a two-way buffer body and a first trigger member and a second trigger member for triggering the two-way buffer body, and the two ends of the two-way buffer body are respectively provided with a hanging wheel assembly, and the lower end of the hanging wheel assembly is connected to an installation box. The two-way buffer body can be slidably arranged in the sliding door track, and the first trigger member and the second trigger member are respectively fixed at the two ends of the sliding door track, and the installation box is connected to the sliding door. When the sliding door is about to be fully opened or fully closed, the first trigger member and the second trigger member will respectively trigger the two-way buffer body, and the sliding door is driven to open or close slowly through the two-way buffer body. However, there is still a problem that after the sliding door is fully opened, the door body is embedded in the wall as a whole, making it difficult for the user to push the door out when closing the door, which brings inconvenience to the user.

DETAILED DESCRIPTION Embodiment 1:

[0017] like Figures 1 to 7As shown, the push-rebound bidirectional sliding door buffer of the present invention comprises a bidirectional buffer body 1 and a first triggering member 2 and a second triggering member 3 for triggering the bidirectional buffer body 1. The first triggering member 2 is used for triggering when opening the door, and the second triggering member 3 is used for triggering when closing the door. The two ends of the bidirectional buffer body 1 are respectively provided with a hanging wheel assembly 4, and the lower end of the hanging wheel assembly 4 is connected to a mounting box 5 through a screw. Usually, the hanging wheel assembly 4 on one side is fixedly connected to the bidirectional buffer body 1, and the hanging wheel assembly 4 on the other side is separately connected to the bidirectional buffer body 1. A push-rebound mechanism 6 is connected to the mounting box 5 on the fixed connection side. The push-rebound mechanism 6 comprises a shell 7, a movable bracket 8, a tension spring 9, an energy storage buckle 10, an energy release rod 11, a first baffle 12, a second baffle 13 and a third baffle 14. The front end of the inner cavity of the shell 7 is provided with a first linear slide 15 and a change-of-direction arc slide 16 that smoothly transitions with the end of the first linear slide 15, and an opening 17 is provided on one side of the shell 7. For easy assembly, the housing 7 is composed of an upper housing and a lower housing. To improve strength, a metal sheath 701 is usually provided outside the housing 7. The movable bracket 8 is slidably installed in the housing 7, and a first triggering portion 18 extending out of the opening 17 is provided at the front end of the movable bracket 8. One end of the tension spring 9 is connected to the front end of the housing 7, and the other end is connected to the rear end of the movable bracket 8. The front end of the energy storage buckle 10 is rotatably connected to the front end of the movable bracket 8 through a rotating shaft 19, and is located behind the first triggering portion 18. The energy storage buckle 10 is provided with a U-shaped groove 20 adapted to the movable bracket 8, a front guide shaft 21 and a rear guide shaft 22 matched with the first linear slide 15 and the change-direction arc slide 16, and a second triggering portion 23 extending out of the opening 17. By giving way to the U-shaped groove 20, the energy storage buckle 10 can rotate at a large angle on the movable bracket 8. The energy release rod 11 is movably arranged in the housing 7, and a release button 25 extending from the front end of the housing 7 is provided at its front end, and a push portion 26 for pushing the energy storage buckle 10 away from the direction-changing arc-shaped slide groove 16 is provided at its rear end. A reset spring 24 is provided between the energy release button 25 and the housing 7 for resetting the energy release button 25 after being pressed. The first baffle 12, the second baffle 13 and the third baffle 14 are all installed in the sliding door track, and cooperate with the second trigger portion 23, the first trigger portion 18 and the release button 25 respectively.

[0018] Preferably, the second triggering part 23 is higher than the first triggering part 18. The first baffle 12 is used to block the second triggering part 23, and the second baffle 13 is used to block the first triggering part 18. During assembly: the second baffle 13 should be on the inside, and the first baffle 12 should be on the outside. A torsion spring 27 is provided on the rotating shaft 19 to drive the energy storage buckle 10 to rotate inward. A clearance notch 28 is provided at the rear end of the first linear slide 15. When the second triggering part 23 is close to the first baffle 12, the rear guide shaft 22 enters the clearance notch 28, so that the energy storage buckle 10 can be pressed and retracted at this position. When the sliding door is almost fully opened (the door body is almost embedded in the wall as a whole), the lower first triggering part 18 can pass through the first baffle 12 normally, and the second triggering part 23 is blocked by the first baffle 12, thereby driving the sliding of the energy storage buckle 10 and the movable bracket 8, and then driving the extension of the tension spring 9. When the energy storage buckle 10 slides to the position of the direction-changing arc-shaped slide groove 16, the rear guide shaft 22 enters the direction-changing arc-shaped slide groove 16 and changes direction, so that the second trigger part 23 enters the housing 7 (see FIG. Figure 7 ), at this time, the second trigger part 23 is separated from the first baffle 12 to complete the energy storage process of the tension spring 9. Usually, after the energy storage is completed, the sliding door continues to slide a short distance to open in place. At this time, when the sliding door is pushed further, the collision between the energy release button 25 and the third baffle 14 will be triggered, so that the energy release rod 11 pushes the energy storage buckle 10 to leave the deflection arc-shaped slide groove 16, and then the tension spring 9 can pull the movable bracket 8 and the energy storage buckle 10 to reset. Since the second baffle 13 is blocked by the first trigger part 18, the sliding door can be driven to pop out. During the pop-up process, in order to prevent interference between the second trigger part 23 and the first baffle 12, when the second trigger part 23 is close to the first baffle 12, the rear guide shaft 22 enters the clearance gap 28, so that the energy storage buckle 10 can be pressed and retracted at this position, so that it can pass through the first baffle 12 normally. When the energy storage buckle 10 leaves the first baffle 12, it can automatically reset under the action of the torsion spring 27.

[0019] Preferably, when the first baffle 12 hits the second trigger part 23 to make the rear guide shaft 22 enter the direction-changing arc-shaped slide groove 16, the first trigger member 2 synchronously triggers the bidirectional buffer body 1 to perform buffering, so as to achieve synchronous completion of energy storage and buffering.

[0020] Preferably, the distance between the front guide shaft 21 and the rear guide shaft 22 is greater than the width of the clearance gap 28. So that before the rear guide shaft 22 enters the clearance gap 28, the front guide shaft 21 has left the clearance gap 28, so as to ensure the stability of the sliding and rotation of the energy storage buckle 10.

[0021] Preferably, the end surfaces of the first triggering part 18 and the second triggering part 23 are both provided with rubber pads 29 for buffering during collision and reducing the sound.

[0022] Preferably, the first baffle 12 and the second baffle 13 are integrally formed, and a first positioning rod 30 is provided at the rear end, and a second positioning rod 31 is provided at the rear end of the third baffle 14. Since the present structure has very high requirements on the installation position accuracy of the first baffle 12, the second baffle 13, and the third baffle 14, the first positioning rod 30 and the second positioning rod 31 are provided to achieve precise installation. During installation: it is only necessary to align the ends of the first positioning rod 30 and the second positioning rod 31 with the edge of the door frame.

[0023] Preferably, a reinforcement ring 32 is sleeved on the rear guide shaft 22 to improve the strength and wear resistance of the rear guide shaft 22 .

[0024] Preferably, the rear end of the inner cavity of the housing 7 is provided with second linear slide grooves 33 on both sides, and the movable bracket 8 is provided with a first guide rail 34 that cooperates with the second linear slide grooves 33 to improve the sliding stability of the movable bracket 8.

[0025] Preferably, the first triggering portion 18 is provided with a second guide rail 35 that cooperates with the first linear slide groove 15 to improve the sliding stability of the first triggering portion 18. The bottom ends of the housing 7 are provided with third guide rails 36 that cooperate with the door frame guide groove to improve the stability of the housing 7 after installation. Embodiment 2:

[0026] like Figure 8 As shown, the embedded sliding door of the present invention comprises a sliding door track 37 and a sliding door 38 arranged below the sliding door track 38, and the rebound type two-way sliding door buffer a described in Example 1 is installed between the sliding door track 37 and the sliding door 38. Specifically, the two-way buffer body 1 is slidably arranged in the sliding door track 37, the first trigger member 2 and the second trigger member 3 are fixed to the two ends of the sliding door track 37, and then the installation box 5 and the pressing rebound mechanism 6 are installed in the sliding door 38.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
