Abstract

The utility model discloses a conveying chain, belonging to the technical field of driving parts. The conveying chain comprises inner sheets and outer sheets, both of which are sequentially connected by pin rolls, wherein a sleeve is sleeved between the outer sheets on two sides of each pin roll; the inner sheets are sleeved on the sleeves; a roller is sleeved between every two inner sheets on the sleeves; a triangular plate is arranged at the upper end of each outer sheet; a triangular hole is formed in each triangular plate; a square plate is connected between the triangular plates on the outer sheets on two sides of each pin roll; a square hole is formed in the middle of each square plate; and a square notch is formed in the upper part of each square plate. Convex parts protruding outwards are arranged on the outer sheets; upper and lower ends of the convex parts are straight sides; and left and right ends of the convex parts are circular arc sides. According to the conveying chain disclosed by the utility model, the outer sheets on two sides of each pin roll are connected into a whole at the upper parts of the outer sheets by the square plate, so that the entire chain is higher in firmness; and compared with the chain with the same type, the conveying chain disclosed by the utility model is longer in service life.

Description

Conveyer chain

Technical field

The utility model belongs to technical field of transmission, is specifically related to a kind of chain.

Background technology

Along with the development of society and the progress of science and technology, the level of automation of industry is also increasingly high.Wherein the commercial production conveyor line is the important component part of automation of industry, and chain is very important drive disk assembly on the commercial production conveyor line.The chain of prior art structurally comes with some shortcomings, and causes being easy to generate in the use wearing and tearing, distortion, thereby influences the whole service life of chain.

Summary of the invention

The purpose of the utility model is: propose a kind of rational in infrastructurely, firmly, the conveyer chain of long service life is to overcome the deficiency that prior art exists.

For realizing the purpose of the utility model, adopt following technical scheme to be achieved: a kind of conveyer chain includes by sheet and outer plate in bearing pin bonded assembly successively; Be arranged with sleeve between the outer plate of both sides on the bearing pin; Interior sheet is set on the sleeve, is arranged with roller between the two interior sheets on the sleeve, and described outer plate upper end is a set square; Offer delthyrium on the set square; Be connected with a square plate between the set square on the outer plate of both sides, square plate middle part offers a square hole, and square plate top is provided with a square breach.

As preferred version: described outer plate is provided with the male part of protrusion laterally, and described male part upper and lower end is a straight flange, and left and right end is the circular arc limit.

Compared with prior art; The beneficial effect of the utility model is: because the outer plate top of the conveyer chain of this utility model connects as one through the outer plate of a square plate with both sides; Make chain integral body have higher firmness, have longer service life than chain of the same type.
