A group of through grooves 2 9 is respectively provided inside each group of mounting sleeves 8. The mounting head 5 can be detachably installed on the inner side of the mounting sleeve 8. The long bolt 10 movably passes through the through grooves 2 9 and the through grooves Slot 1 6, and a nut 11 is detachably screwed on the outside of the long bolt 10; first, each group of mounting sleeves 8 on a group of side plates 7 is respectively sleeved on the outside of a group of mounting heads 5, so that the through-slot 1 6 and the through-slot 2 9 correspond to each other, and then the long bolt 10 is passed through the through-slot 2 9 and the through-slot 1 6, and the nut 11 is screwed and tightened on the outside of the long bolt 10, so that the mounting head 5 is connected and fixed relative to the mounting sleeve 8, and then all the mounting sleeves 8 on the upper side of the other group of side plates 7 are respectively sleeved on the outside of the corresponding mounting heads 5 on the other side, and are also connected and fixed by the action of the long bolts 10 and the nuts 11. When in use, the connecting mechanisms on both sides act on the side plates 7 on both sides, and between the two groups of side plates 7, the friction energy dissipation blocks 3 are elastically deformed and the friction energy dissipation of the connecting springs 2 and the damping tube 1 causes all the connecting rods 4 to move synchronously relative to the damping tube 1 to achieve buffering.

[0025] It also includes an anti-loosening pad 12, which is movably arranged on the inner side of the long bolt 10 and the nut 11 after installation; after the long bolt 10 and the nut 11 are screwed and tightened, the anti-loosening pad 12 can be supported outward by the installation sleeve 8 to prevent the screw from loosening and improve stability.

[0026] The connecting mechanism includes an outer ring 13, balls 14 and an internal connecting ring 15. The middle part of the outer side of each group of side plates 7 is respectively connected to the inner end of a group of outer rings 13. The inner side of the outer ring 13 is rotatably connected to the outer side of the internal connecting ring 15 through rolling constraints of multiple groups of balls 14. During installation, it can be connected to the outside through the internal connecting ring 15. During movement, the outer ring 13 can move relative to the internal connecting ring 15 through rolling constraints of multiple groups of balls 14, so as to adapt to deformation of the connection, avoid wear and improve reliability.

[0027] It also includes an oiling nozzle 16, and the top of each group of outer rings 13 is respectively connected to the bottom of a group of oiling nozzles 16; the inner wall of the outer ring 13 can be oiled through the oiling nozzles 16, which is convenient for lubrication and maintenance.

[0028] It also includes an oil filling cap 17, and the outer side of the oil filling nozzle 16 and the inner side of the oil filling cap 17 are detachably mounted; after the oil filling cap 17 is mounted on the outer side of the oil filling nozzle 16, the inside of the oil filling nozzle 16 can be sealed and protected to improve reliability.

In addition, the painting can increase the surface beauty and improve the reliability.

[0030] In summary, when a pull-type damping buffer is used, each group of mounting sleeves 8 on a group of side plates 7 is first sleeved on the outside of a group of mounting heads 5, so that the through slot 1 6 and the through slot 2 9 correspond to each other, and then the long bolt 10 is passed through the through slot 2 9 and the through slot 1 6, and the nut 11 is screwed and tightened on the outside of the long bolt 10. After the long bolt 10 and the nut 11 are screwed and tightened, the anti-loosening pad 12 can be used to support the outside through the mounting sleeve 8 to prevent the screw from loosening, so that the mounting head 5 is connected and fixed relative to the mounting sleeve 8, and then all the mounting sleeves 8 on the upper side of the other group of side plates 7 are sleeved on the outside of the corresponding mounting head 5 on the other side, and are also connected and fixed through the long bolt 10 and the nut 11. During installation, it can be connected to the outside through the internal connecting ring 15. When moving, the outer ring 13 can be constrained by the rolling of multiple groups of balls 14 to move relative to the internal connecting ring 15, adapt to the deformation of the connection, avoid wear, and act on the side plates 7 on both sides. Between the two groups of side plates 7, the friction energy dissipation block 3 is elastically deformed and the friction energy dissipation between the connecting spring 2 and the damping tube 1 makes all the connecting rods 4 move synchronously relative to the damping tube 1 to achieve buffering. In addition, the inner wall of the outer ring 13 can be oiled through the oiling nozzle 16 to facilitate lubrication and maintenance. After the oiling cap 17 is installed on the outside of the oiling nozzle 16, the inside of the oiling nozzle 16 can be sealed and protected. The materials of the mounting head 5, the through groove 1 6, the side plate 7, the mounting sleeve 8, the through groove 2 9, the long bolt 10 and the nut 11 increase the rigidity of the body and are corrosion-resistant. In addition, the surface beauty can be increased by painting.
