Detailed Description
As shown in fig. 1 to 7, the two-way centering sliding door buffer of the present invention comprises: the device comprises a shell 1, two groups of sliding block assemblies 2, a tension spring 3 and a damping rod 4. The housing 1 is composed of a first housing 101 and a second housing 102, and is screwed and fixed (or linked in a hot-melt manner) by screws 11 at both ends. The inside both ends of casing 1 are equipped with corresponding first slide rail 103, second slide rail 104, third slide rail 105, casing 1 is inside to be equipped with damping rod mounting groove 106 in the middle, casing 1 upper end is equipped with fluting 107. Both ends of the first slide rail 103 and the second slide rail 104 are provided with downward turning sections 12, and the turning sections 12 are used for turning the first slide block 201 and the second slide block 202. Each of the two sets of slider assemblies 2 is mainly composed of a first slider 201, a second slider 202 and a third slider 203 which are respectively mounted in the first slide rail 103, the second slide rail 104 and the third slide rail 105 of the housing 1. The first sliding blocks 201 are connected through connecting rods 204 hinged with the first sliding blocks, and the upper ends of the first sliding blocks 201 are provided with first hooks 205 extending out of the slots 107 of the shell 1. The upper end of the second slider 202 is provided with a second hook 206 and a third hook 207, the upper end of the third slider 203 is provided with a fourth hook 208, the bottom of the first slider 201 is provided with a first hanging part 209 and a second hanging part 210 which are respectively matched with the second hook 206 and the third hook 207, and the bottom of the second slider 202 is provided with a third hanging part 211 matched with the fourth hook 208. And two ends of the tension spring 3 are respectively connected with the third sliding block 203. The damping rod 4 is movably arranged in a damping rod mounting groove 106 of the housing 1, two ends of the damping rod are respectively aligned with the second slide rail 104, and the damping rod is a pneumatic rod.
Further, a first installation positioning hole 10 is formed in the third slider 203, and a second installation positioning hole 5 matched with the first installation positioning hole 10 is formed in the housing 1. During assembly, the third slider 203 is fixed by inserting positioning pins into the first mounting positioning hole 10 and the second mounting positioning hole 5, so that the tension spring can be conveniently mounted.
Further, the first slide rail 103, the second slide rail 104, and the third slide rail 105 are respectively in sliding fit with the first slide rail 103, the second slide rail 104, and the third slide rail 105 through the cylinders 6, 6', 6 ″ on both sides.
Further, a V-shaped bottom 7 is disposed at the bottom of the second slide rail 104, and a groove 8 is formed in the V-shaped bottom 7 to form the third hanging portion 211.
Further, a reinforcing protrusion 9 is arranged on the second hook 206 of the second slider 202 to improve the strength of the second hook 206, so as to improve the impact resistance.
During installation, the shifting piece is installed on the upper door frame matched with the door body of the sliding door, the buffer is installed on the door body of the sliding door, and the door body is in a central position at the moment. When the door is used, the door body is pulled leftwards, the shifting part of the shifting piece moves along the groove of the shell, and after the shifting piece hits the first hook of the first sliding block, the shifting part of the shifting piece pushes the first hook leftwards, so that the first sliding block, the second sliding block and the third sliding block are driven to move leftwards synchronously, at the moment, the tension spring is stretched, and the damping rod extends automatically. The door body continues to move leftwards, after the first sliding block and the second sliding block respectively enter the turning sections of the first sliding rail and the second sliding rail, turning is carried out, the shifting portion of the shifting piece is separated from the first hook, and the door body can continue to move leftwards. When the door body is reset, the door body moves rightwards, the shifting part of the shifting piece collides with the second hook of the first sliding block, so that the first sliding block and the second sliding block are driven to rotate under the action of the shifting piece and are separated from the turning sections of the first sliding rail and the second sliding rail respectively, the tension spring and the damping rod slowly return to reset at the moment, the first sliding block, the second sliding block, the third sliding block and the sliding door are finally driven to slowly return to the middle position, and the returning buffering effect when the door is closed rightwards is achieved. Similarly, if the sliding door continues to move towards the right side, the same effect can be achieved.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
