Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an antiskid type chain bucket conveyor chain, including link joint 1, sleeve 2 and roller 3, the chain is formed by the concatenation of a plurality of end to end's 1 two sets of link joint combinations of link joint, jack 102 has all been seted up to 1 right-hand members of two sets of link joints, and inlay between two sets of jack 102 and be equipped with sleeve 2, the outside of sleeve 2 is located and is equipped with roller 3 between two sets of link joint 1, spout 301 has been seted up to roller 3's inboard, the inboard cunning of spout 301 has ball 7, the inboard of spout 301 is located to inlay between spout 301 and the ball 7 and is equipped with second extrusion spring 6, the setting of second extrusion spring 6, can make ball 7 produce the extrusion force to sleeve 2 directions, thereby be convenient for ball 7 slide into the inside in ball groove 201, thereby the production of the excessive rotation phenomenon of roller 3 has been reduced, the phenomenon of skidding between chain. Specifically, as shown in fig. 1-3, the outer side of the right end of each of the two groups of link plates 1 is provided with an outer splicing groove 101, the inner side of the left end of each of the two groups of link plates 1 is provided with an inner splicing groove 104, the inner sides of the two opening ends of the sleeve 2 are respectively embedded with a locking block 4, the inner side of the sleeve 2 is positioned between the two groups of locking blocks 4 and embedded with a first extrusion spring 5, the horizontal section of each locking block 4 is of a convex structure, the inner parts of the left ends of the two groups of link plates 1 are respectively provided with a locking hole 103 matched with the locking block 4, the locking holes 103 and the locking blocks 4 are in transition fit, one side of the outer part of the sleeve 2 close to the balls 7 is provided with a plurality of sets of ball grooves 201 in an annular array manner, the plurality of sets of ball grooves 201 facilitate the sliding of the balls 7 into the inner grooves, the arrangement of the outer splicing grooves 101 and the splicing grooves, the first pressing spring 5 is arranged to generate outward pressing force on the two sets of locking pieces 4, so that the locking pieces 4 can slide into the locking holes 103 conveniently.
