Description

Buffering formula silence tow chain convenient to dismouting Technical Field The utility model relates to the field of drag chains, in particular to a buffer type mute drag chain convenient to disassemble and assemble. Background At present, the drag chain is widely applied to a plurality of fields such as numerical control machine tools, stone machinery, glass machinery, door and window machinery, injection molding machines, manipulators, hoisting and transporting equipment, automatic warehouses and the like, and can pull and protect cables, oil pipes, air pipes, water pipes and the like which are arranged in the machinery, and meanwhile, the whole machinery looks more attractive. The general drag chain consists of a plurality of chain links, the chain links in the prior art are assembled by a left side plate, a right side plate, an upper cross rod and a lower cross rod in a shape of a Chinese character kou, the cross rods are fixedly connected with the left side plate and the right side plate of the chain links in a lap joint mode, buckling positions exist at the lap joint positions, enough space is not reserved for inserting tools for disassembly, excessive time can be wasted when a line is disassembled, the plurality of chain links can be connected through elastic bodies with circular shafts at the two ends, when the drag chain rotates relatively, the elastic bodies can deform along with the elastic bodies, and a limiting block of one chain link is inserted into a limiting groove of the other chain link, wherein the limiting groove is used for limiting the rotation track of the limiting block, namely the motion track of the drag chain. When the drag chain reciprocates at a high speed, the limiting block can collide with the inner walls at two sides of the limiting groove, so that noise is generated. Disclosure of utility model In order to achieve the above purpose, the utility model aims to provide a buffer type mute drag chain convenient to disassemble and assemble, which can solve the defects of common drag chain noise reduction effect and high line time cost in the prior art, thereby providing a mute drag chain with good noise reduction effect and convenient disassembly and assembly. The utility model provides the following technical scheme: The buffer mute drag chain comprises a plurality of links connected end to end, wherein each link comprises a link left side plate, a link right side plate, an elastic body and a cross rod, the link left side plate and the link right side plate form a main body, the link left side plate and the link right side plate are arranged in a mirror image mode, the elastic body and the cross rod are detachably arranged on the main body, two branch pieces made of elastic materials extend out of the middle part of the elastic body and are respectively positioned on the upper side and the lower side of a central round hole of an inner cavity surface of a joint of two adjacent main bodies, a limiting block and a limiting groove matched with the limiting block are arranged on the main body, when the links reciprocate, the limiting block of the link can perform circular motion at a certain angle in the limiting groove of the adjacent link, and when the limiting block and the limiting groove collide at the maximum angle and the minimum angle, rotation is stopped, meanwhile when the two adjacent links perform relative rotation, the main bodies can rotate and contact the branch pieces, so that the branch pieces elastically deform and then rotate to the other adjacent links together, the two branch pieces collide and squeeze, the two branch pieces are respectively, the main body rotates, and the limiting block and the limiting groove is matched with the limiting groove, and the limiting groove. As a further scheme of the utility model, the two ends of the elastic body are respectively provided with a round shaft, the two sides of the left side plate and the right side plate of the chain link are respectively provided with a shaft hole, and the chain links are connected in a mode of matching the round shafts with the shaft holes.
