The utility model relates to a linkage buffer door closer structure for double-door sliding door as shown in fig. 1-2, comprising a guide rail 1, a door closer body 2, a first rack 3, a gear 4, a second rack 5, a buffer sleeve 6, a buffer rod 7 and an elastic member 8, wherein the door closer body 2 is fixedly arranged on the guide rail 1, the output end of the door closer body 2 is connected with the first rack 3, the gear 4 is arranged in the middle of the guide rail 1, the first rack 3 and the second rack 5 are both engaged with the gear 4, the first rack 3 and the second rack 5 are respectively arranged on both sides of the gear 4, the first rack 3 and the second rack 5 are both connected with the guide rail 1 in a sliding manner, the first rack 3 and the second rack 5 are respectively provided with a buffer sleeve 6, the two buffer sleeves 6 are opposite in position, each buffer sleeve 6 is connected with a buffer rod 7 in a sliding manner, buffer rod 7 is connected with the push-and-pull door, elastic component 8 is located between buffer sleeve 6 and the buffer rod 7, 8 one end of elastic component with buffer sleeve 6 is connected, 8 other ends of elastic component with buffer rod 7 is connected.

It should be noted that the door closer body 2 may be a hydraulic sliding door closer, or may be a pneumatic sliding door closer.

It should be noted that fig. 1 is a plan view of the present invention when the double-door sliding door is completely closed.

Further, the buffer sleeve 6 comprises a sleeve 61 and a cover plate 62, the buffer rod 7 comprises a sliding portion 71 and a push rod portion 72, the sliding portion 71 of the buffer rod 7 is inserted into the sleeve 61 and is slidably connected with the sleeve 61, the push rod portion 72 of the buffer rod 7 penetrates through the cover plate 62, and the cover plate 62 is fixedly arranged on the sleeve 61.

More specifically, through setting up sleeve 61 and apron 62, thereby make buffer rod 7 can receive apron 62 and the inner wall of sleeve 61 is spacing, avoid when the sliding door slides and opens buffer rod 7 slide excessively to lead to the elastic component 8 stretch excessively and lose elasticity.

Further, the elastic member 8 is a spring, one end of the elastic member 8 is fixedly connected to the inner wall of the sleeve 61, and the other end of the elastic member 8 is fixedly connected to the sliding portion 71 of the buffer rod 7.

More specifically, the elastic member 8 is disposed in the sleeve 61, so that the elastic member 6 can be protected from external dust and the like.

Further, the guide rail 1 is further fixedly provided with an anti-collision rubber 11 for preventing the first rack 3 from sliding excessively.

More specifically, by providing the anti-collision rubber 11, the first rack 3 can be prevented from sliding excessively.

Further, a sliding block is fixedly arranged on the first rack 3, a sliding rail is fixedly arranged on the guide rail 1, and the sliding block is matched with the sliding rail to enable the first rack 3 to be in sliding connection with the guide rail 1.

The second rack 5 is mounted in the same manner as the first rack 3.

More specifically, by providing a slide rail and a slider, it is possible to ensure smooth sliding of the first rack 3 and the second rack 5.

When the utility model is used, the door closer body 2 drives the first rack 3 to slide, so as to drive the gear 4 to rotate, and further drive the second rack 5 to slide, so that the buffer sleeves 6 arranged on the first rack 3 and the second rack 5 are relatively close to each other or are away from each other; when the door closer body 2 drives the first rack 3 to slide so that the buffer sleeves 6 are relatively close to each other, the sleeve 61 and the buffer rod 7 are relatively displaced to be close to each other so that the elastic members 8 are stressed and compressed, thereby reducing the instant stress of the buffer rod 7, avoiding damage caused by the fact that the door connected with the buffer rod 7 is subjected to overlarge instant stress, the door closer body 2 continuously drives the first rack 3 to slide until the first rack 3 reaches the end point of the stroke, at the moment, two doors are in an unclosed state, at the moment, the distance between the two doors is smaller than the sum of length compression variables of the two elastic members 8, at the moment, as the two buffer rods 7 are respectively connected with one elastic member 8, the elastic members 8 can elastically reset, so that the two doors are closed, and when the two doors are completely closed, the elastic members 8 are still in a compressed state, therefore, the momentum of the two doors in collision is less when the two doors are closed, and the elastic part 8 always applies pressure to the two doors, so that the two doors are tightly closed, and the condition that the doors are damaged due to collision when the doors are closed can be avoided; on the contrary, when the door closer body 2 drives the first rack 3 to slide so that the buffer sleeve 6 is away from the back, the sleeve 61 and the buffer rod 7 are relatively displaced and away from each other so that the elastic part 8 is stressed and stretched, so that the instant stress of conveying the buffer rod 7 is reduced, the damage caused by the instant overlarge stress of the door connected with the buffer rod 7 is avoided, and the door closer body 2 continues to drive the first rack 3 to slide until the door is completely opened.

The utility model has the advantages that: 1. by arranging the first rack 3, the gear 4 and the second rack 5, one door closer body 2 can control the closing of the double-door type sliding door, so that the cost is reduced; 2. through setting up cushion collar 6, buffer beam 7 and elastic component 8, double-door formula push-and-pull door is connected with buffer beam 7, and elastic component 8 can cushion double-door formula push-and-pull door and avoid the door to damage, can continuously exert pressure to double-door formula push-and-pull door when closed again simultaneously and guarantee that the door is forbidden.

Various other changes and modifications may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such changes and modifications should fall within the scope of the present invention.
