The utility model provides a double-row chain convenient for disassembly and assembly, which comprises an inner chain plate, a roller and a gasket, wherein the roller is rotationally connected on the inner chain plate, and the double-row chain also comprises a new bolt, a side gasket and a top pin, one end of the new bolt is provided with a base, the other end is provided with a groove, the side of one end of the new bolt far away from the base is provided with a pin hole and a slotted hole, the slotted hole is communicated with the groove, the side gasket is provided with a round hole, and the diameter of the round hole is consistent with the thickness of the new bolt;

the knock pin comprises a cylindrical part and a conical part, the taper of the conical part is 1.

In a preferred embodiment, the slots have upper and lower edges and are aligned with each other.

In a preferred embodiment, the side spacers abut the side faces of the two inner link plates when installed.

In a preferred embodiment, the wire is inserted into the pin hole and wound on the new pin, and the stud is inserted into the slot hole and the through hole.

In a preferred embodiment, the new plug, the side washer and the top pin are all carbon structural steel.

In a preferred embodiment, the tip end of the conical portion has a spherical shape.

The utility model discloses a technological effect and advantage:

only need can install new bolt alignment inner link board, roller and a plurality of gasket, single new bolt installation, simplified the installation greatly, the knock pin plays guide and backstepping effect, makes things convenient for new bolt to insert smoothly and shifts out, when having reduced new bolt and inserting, to the requirement of radial error, chain maintenance easy dismounting, easy and simple to handle, labour saving and time saving, simple structure, reliable can use widely in the iron and steel factory.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

A double-row chain convenient to disassemble and assemble is shown in figures 1-8 and comprises inner chain plates, rollers and gaskets, wherein the rollers are rotatably connected to the inner chain plates, the double-row chain also comprises a new bolt 1, side gaskets 2 and a top pin 3, one end of the new bolt 1 is provided with a base 12, the other end of the new bolt is provided with a groove 11, the side surface of one end, away from the base 12, of the new bolt 1 is provided with a pin hole 13 and a groove hole 14, the groove hole 14 is communicated with the groove 11, the side gaskets 2 are provided with two round holes 21, the diameter of the round holes 21 is consistent with the thickness dimension of the new bolt 1, namely the new bolt 1 can be inserted into the round holes 21, and the side gaskets 2 connect the two inner chain plates into a whole to play a role in strengthening the tensile strength of the chain;

the knock pin 3 includes cylinder portion and circular cone portion, and the tapering of circular cone portion is 1:10, the cylindrical portion is of the same size as the recess 11, and the cylindrical portion is provided with a through hole 31, and when the cylindrical portion is located in the recess 11, the slot 14 is aligned with the through hole 31.

The slot 14 has upper and lower sides and is aligned with each other, i.e. the slot 14 is aligned with the through hole 31, and the new plug pin 1 and the knock pin 3 are detachably connected by inserting the stud.

When the chain guard is installed, the side gasket 2 is attached to the side surfaces of the two inner chain plates.

The novel pin comprises a pin hole 13 and a new pin 1, wherein the new pin 1 is inserted into the pin hole and wound on the new pin, and the iron wire can be prevented from sliding out of the inner chain plate and the roller.

The new bolt 1, the side gasket 2 and the knock pin 3 are all made of carbon structural steel, and have high strength and long service life.

The top end of the conical part is spherical, so that a hammer can conveniently strike the top end of the conical part to eject the new bolt 1.
