[0039] like Figures 1 to 10 As shown, a push-button buffer device is used to cooperate with a guide rail 1 to assist in the opening and closing process of the door panel 3. A roller 4 connected to the door panel 3 of the pocket door is slidably connected inside the guide rail 1. A first fixed plate 5 and a second fixed plate 9 are respectively arranged on both sides of the guide rail. A spring fixed plate 6 and a movable plate 8 are arranged sequentially from left to right between the first fixed plate 5 and the second fixed plate 9. The spring fixed plate 6 and the movable plate 8 are connected by a connecting spring 61. A connecting groove 82 is formed on the right side of the upper end face of the movable plate 8, and a lock groove 8 is connected to the left side of the connecting groove 82. 1. The locking groove 81 includes a large V-shaped groove 83 and a small V-shaped groove 86. The left ends of the large V-shaped groove 83 are connected to the left ends of the small V-shaped groove 86, respectively. The angle of the large V-shaped groove 83 is smaller than that of the small V-shaped groove 86. The large V-shaped groove 83 includes a first inclined groove 84 and a second inclined groove 85 connected to its right end. The right end of the first inclined groove 84 is connected to the connecting groove 82. The angle of the small V-shaped groove 86 is located between the left and right ends of the large V-shaped groove 83. The second fixing plate 9 is provided with a hook that cooperates with the locking groove 81.

[0040] Using the push-to-close buffer device of this application, the push-to-close buffer device is set in the guide rail 1. A roller 4 connected to the door panel 3 is slidably connected in the guide rail 1. When people manually push the door panel 3 and the roller 4 to the right, the roller 4 contacts the movable plate 8 and drives the movable plate 8 to move to the right. The locking groove 81 on the movable plate cooperates with the hook. The hook is locked in the locking groove 81. The door panel 3 of the pocket door and the roller 4 connected to it do not move. When the door panel 3 and the roller 4 connected to it are pressed to the right again, the hook disengages from the locking groove 81. The roller 4 moves to the right first and then to the left. Under the action of the connecting spring 61, the door panel 3 and the roller 4 are driven to reset. This can better achieve the function of closing the door panel 3 when pressed.

[0041] The small V-shaped groove 86 includes a third inclined groove 87, a fourth inclined groove 88, and a fifth inclined groove 89. The third inclined groove 87 is connected to the fifth inclined groove 89 through the fourth inclined groove 88. The right end of the third inclined groove 87 is connected to the left end of the first inclined groove 84. The right end of the fifth inclined groove 89 is connected to the left end of the second inclined groove 85. The connection between the third inclined groove 87 and the fourth inclined groove 88 is located at the bend of the small V-shaped groove 86.

[0042] The bottom surfaces of the first inclined groove 84 and the second inclined groove 85 are both inclined. The bottom height of the left end of the first inclined groove 84 is higher than the bottom height of the right end of the first inclined groove 84. The bottom height of the right end of the first inclined groove 84 is the same as the bottom height of the connecting groove 82. The bottom height of the left end of the second inclined groove 85 is lower than the bottom height of the right end of the second inclined groove 85. The bottom height of the right end of the second inclined groove 85 is higher than the bottom height of the connecting groove 82. The bottom height of the left end of the first inclined groove 84 is the same as the bottom height of the fifth inclined groove 89. The bottom heights of the left end of the first inclined groove 84, the bottom height of the third inclined groove 87, the bottom height of the fourth inclined groove 88, and the bottom height of the fifth inclined groove 89 are sequentially decreasing.

[0043] After the door panel 3 and its connected roller 4 move to the right, the hook enters the connecting groove 82, passes through the connecting groove 82 into the first inclined groove 84, then passes through the third inclined groove 87 to the fourth inclined groove 88, and arrives at the corner of the small V-shaped groove 86. At this time, the hook engages with the lock groove 81. Then, the door panel 3 is pressed to the right, and the door panel 3 moves to the right under the action of the pressing force. At this time, the hook moves from the fourth inclined groove 88 to the fifth inclined groove 89. Then, the door panel 3 moves to the left under the elastic action of the elastic spring 61. The hook passes through the fifth inclined groove 89, the second inclined groove 85 and the connecting groove 82 in sequence, so that the hook disengages from the movable plate 8. The door panel 3 and its connected roller 4 continue to move to the left to reset the door panel.

[0044] A first magnet is provided on the left side of the first fixing plate 5, and a second magnet is provided on the left side of the roller component 4 to cooperate with the first magnet. The first magnet and the second magnet are attracted by opposite poles, which facilitates further reinforcement of the reset of the door panel 3 and the roller component 4 connected thereto. When the door panel 3 and the roller component 4 connected thereto move to the left and are positioned close to the first magnet, the first magnet and the second magnet are attracted by opposite poles and interact with each other, thereby reinforcing the reset of the door panel 3 and the roller component 4 connected thereto.

[0045] The hook includes a hook rod 91 rotatably connected to the second fixing plate 9. The other end of the hook rod 91 is provided with a hook head 92 that is perpendicular to the axis of the hook rod 91. The hook head 92 is configured to cooperate with the locking groove 81. The hook head 92 is configured to facilitate its engagement with the small V-shaped groove 86 in the locking groove 81.

[0046] The roller component 4 includes a first connecting seat 41 and a second connecting seat 42 connected to the door panel 3. The first connecting seat 41 and the second connecting seat 42 are respectively provided with a first roller 43 and a second roller 44 that are slidably connected to the guide rail 1. The roller component 4 makes it easier for people to push the door panel 3 with less force, thus improving the convenience of opening the door panel 3.

[0047] The first connecting seat 41 is positioned further away from the second fixing plate 9 than the second connecting seat 42. A first limiting rod 45 is provided on the first connecting seat 41. A first limiting groove 51 is provided on the first fixing plate 5 to cooperate with and limit the first limiting rod 45. The function of the first limiting rod 45 and the first limiting groove 51 is to facilitate the reset of the door panel and reduce the impact force of the door panel on the object on its left side.

[0048] The lower end face of the spring fixing plate 6 is provided with a through groove 62 for the first limiting rod 45 to move through, which further facilitates the restriction of the movement direction of the roller 4 and the door panel 3 and regulates the movement trajectory of the door panel 3.

[0049] The movable plate 8 is provided with a slot on the side facing the first fixed plate 5, and the slot is configured to cooperate with the first limiting rod 45.

[0050] A limiting plate 7 is provided between the spring fixing plate 6 and the movable plate 8. A groove 71 is provided on the lower part of the side of the limiting plate 7 facing the spring fixing plate 6. The axes of the first limiting groove 51, the through groove 62 and the groove 71 are aligned.

[0051] A guide member 2 is fixedly installed inside the guide rail 1. The first fixing plate 5, the spring fixing plate 6, the limiting plate 7, and the second fixing plate 9 are all fixedly connected to the guide member 2. The guide member 2 is slidably arranged with the movable plate 8. The first limiting groove 51, the through groove 62, and the abutment groove 71 are all arranged parallel to the guide member 2.

[0052] A rubber pad for cushioning the first limiting rod 45 is vertically arranged on the right side wall of the card slot, and a rubber pad for cushioning the first limiting rod 45 is also vertically arranged on the left side wall of the first limiting slot 51.

[0053] like Figure 11As shown, a locking device is provided between the movable plate 8 and the guide rail 1. The locking device includes a connecting block 101 fixedly connected to the side wall of the movable plate 8. The connecting block 101 is connected to a first helical tooth 103 via a traction spring 102. A swing shaft 106 and a push shaft 107 are rotatably mounted on the guide rail 1. A swing plate 105 and a push plate 108 are respectively connected to the side walls of the swing shaft 106 and the push shaft 107. The side of the swing plate 105 facing the movable plate 8 is provided with a locking device. The first helical tooth 103 is fitted with the second helical tooth 104. The swing shaft 106 and the push shaft 107 are respectively coaxially equipped with a first gear 109 and a second gear 110. The swing shaft 106 is equipped with a torsion spring. The two ends of the torsion spring are respectively abutted or fixedly connected to the guide rail 1 and the swing plate 105. The push plate 108 is located to the right of the first helical tooth 103. The swing shaft 106 is located on one side of the second fixed plate 9 and is set close to the second fixed plate 9.

[0054] When the lock groove 81 and the hook are about to engage, the movable plate 8 moves, causing the first helical tooth 103 to move closer to the second helical tooth 104. Then, the second helical tooth 104 engages with the first helical tooth 103. At this time, the lock groove 81 and the hook are engaged. Then, when the door panel 3 and the roller 4 are pressed to the right, the first helical tooth 103 moves to the right relative to the second helical tooth 104. The first helical tooth 103 also pushes the push plate 108 to rotate counterclockwise, which is connected by the meshing of the first gear 109 and the second gear 110. The swing shaft 106 and its connected swing plate 105 rotate clockwise. At this time, the first helical tooth 103 and the second helical tooth 104 separate. Under the action of the connecting spring 61, the movable plate 8 and the roller 4 that abuts against the movable plate 8 move to the left. After the first helical tooth 103 separates from the push plate 108, the torsion spring on the swing shaft 106 does not immediately return to its counterclockwise position due to the inertia of the torsion spring caused by the clockwise rotation of the swing shaft 106. The swing shaft 106 returns to its counterclockwise position after a period of time.

[0055] The first helical tooth 103 is slidably connected to the side wall of the movable plate 8, so that the first helical tooth 103 does not detach from the movable plate 8.

[0056] Based on the above embodiments, a pocket door is provided, including a door frame, a door panel, and the aforementioned push-to-open buffer device. The door frame is provided with the guide rail 1, and the roller 4, which is slidably connected to the guide rail 1, is connected to the door panel 3. When people need to open the door panel, they manually slide the door panel to move it to the right. Through the cooperation of the hook and the lock groove 81, the door panel is locked in a hidden groove in the wall. When people need to close the door panel, they press the door panel, and the door panel moves to the right under the action of the pressing force. Then, the door panel is reset under the action of the connecting spring 61, which facilitates the opening and closing of the door panel.
