The chain comprises an inner chain link assembled by an inner chain plate and a sleeve in an interference fit manner and an outer chain link assembled by an outer chain plate and a pin shaft in an interference fit manner, wherein the inner chain link and the outer chain link form a hinged joint through the sleeve and the pin shaft, and the inner chain link and the outer chain link rotate relatively; a sealing structure is arranged between the inner chain plate and the outer chain plate and consists of a rubber sealing ring and a sealing cover, the rubber sealing ring is arranged in the sealing cover and sleeved on the sleeve, and under the compression action of the inner chain plate and the outer chain plate, the rubber sealing ring is in close contact with the outer chain plate. The utility model discloses the effectual powdery material that has prevented has advanced between sleeve and the round pin axle, has reduced the wearing and tearing of sleeve and round pin axle, makes chain life prolong more than 1 doubly, about 2 years of life in the past, can reach more than 4 years now basically, excellent in use effect, simple structure, low in production cost, the practicality is strong.

Description

Prevent material wearing and tearing and carry chain

Technical Field

The utility model relates to a carry the chain, specifically a prevent material wearing and tearing carry chain.

Background

Ordinary conveying chain life is short, can not satisfy customer's demand, and the reason is that the chain fully contacts with carrying powdery material when the transportation, and powdery material can get into in the clearance in the middle of sleeve and the round pin axle, has increased the wearing and tearing speed of sleeve and round pin axle in other words having added the abrasive material between sleeve and round pin axle to the wearing and tearing of chain have been accelerated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem, thereby providing a prevent material wearing and tearing conveyor chain.

The utility model provides a problem, the technical scheme who adopts is:

a material abrasion prevention conveying chain comprises an inner chain link and an outer chain link, wherein the inner chain link is formed by assembling an inner chain plate and a sleeve in an interference fit mode, the outer chain link is formed by assembling an outer chain plate and a pin shaft in an interference fit mode, the inner chain link and the outer chain link form a hinge joint through the sleeve and the pin shaft, and the inner chain link and the outer chain link rotate relatively; a sealing structure is arranged between the inner chain plate and the outer chain plate and consists of a rubber sealing ring and a sealing cover, the rubber sealing ring is arranged in the sealing cover and sleeved on the sleeve, and under the compression action of the inner chain plate and the outer chain plate, the rubber sealing ring is in close contact with the outer chain plate.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:

the chain has the advantages that powdery materials are effectively prevented from entering between the sleeve and the pin shaft, abrasion of the sleeve and the pin shaft is reduced, the service life of the chain is prolonged by more than 1 time, the service life is about 2 years before, at present, the service life can basically reach more than 4 years, and the using effect is good.

Secondly, the structure is simple, the production cost is low, and the practicability is strong.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

FIG. 2 is a schematic view of a portion of the enlarged structure of A in FIG. 1;

FIG. 3 is a partial enlarged structural view of B in FIG. 2;

in the figure: a pin shaft 1; an angle bracket 2; an outer link plate 3; an inner link plate 4; a sleeve 5; a sealing cover 6; and a rubber seal ring 7.

The specific implementation mode is as follows:

the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.

Referring to fig. 1, 2 and 3, the material abrasion prevention conveying chain comprises an inner chain link assembled by two inner chain plates 4 and two sleeves 5 in an interference fit manner, and an outer chain link assembled by two outer chain plates 3 and two pin shafts 1 in an interference fit manner, wherein angle brackets 2 are sleeved at two ends of the two pin shafts 1, the inner chain link and the outer chain link form a hinge joint through the sleeves 5 and the pin shafts 1, and the inner chain link and the outer chain link rotate relatively; be provided with seal structure between inner chain plate 4 and the outer chain plate 3, seal structure comprises rubber seal 7 and sealed lid 6, rubber seal 7 arranges sealed lid 6 in and the suit is on sleeve 5, because rubber seal 7 has certain elasticity, under the compressing tightly effect of inner chain plate 4 and outer chain plate 3,

rubber seal

7 and 3 in close contact with of outer chain plate, thereby make rubber seal 7 and sleeve 5, outer chain plate 3 zonulae occludens is as an organic whole, prevent that the dust from getting into between sleeve 5 and the round pin axle 1, play the sealing action.

Through set up the seal structure of constituteing by rubber seal 7 and sealed lid 6 between inner chain plate 4 and outer chain plate 3, will have elastic rubber seal 7 to compress tightly when inner chain plate 4 and outer chain plate 3 assemble for rubber seal 7 and outer chain plate 3 in close contact with play the sealing action, hinder dust and foreign matter to enter into between round pin axle 1 and the sleeve 5, reduce the wearing and tearing speed of chain.

The utility model discloses the effectual powdery material that has prevented has advanced between sleeve 5 and the round pin axle 1, has reduced sleeve 5 and round pin axle 1's wearing and tearing, makes chain life prolong more than 1 times, about 2 years of life before, can reach more than 4 years now basically, excellent in use effect, simple structure, low in production cost, the practicality is strong.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.

Claims

1.
