Detailed Description

The present invention will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

As shown in fig. 1-3, in order to achieve the above purpose, the technical solution adopted by the present invention is: the utility model provides an antifatigue chain, including a plurality of interconnected chain links, the chain link includes outer link joint, the inner link joint, the staff, the tubule, inner link joint and/or outer link joint include annular planking 1 and waist type inner panel 2, the slot hole has in the middle of the annular planking 1, waist type inner panel 2 chucking is in the slot hole, be equipped with first semicircular notch 11 at slot hole length direction's both ends, waist type inner panel 2 length direction's both ends are equipped with the semicircular notch 21 of second relative with first semicircular notch 11, first, the semicircular notch 11 of second, 21 correspond each other, form the mounting hole 3 that supplies staff and/or tubule to peg graft. The chain plate is divided into two parts, the mounting hole 3 is formed by splicing the two parts, and the small shaft or the small pipe can be clamped by the mounting hole 3, so that a tighter mounting effect is achieved. When the device is installed, the small shaft or the small pipe can be actively inserted into the installation hole 3, or the installation hole 3 can be spliced at the end part of the small shaft or the small pipe to clamp the small shaft or the small pipe.

The two sides of the width direction of the waist-shaped inner plate 2 are spaced from the annular outer plate 1, certain materials can be saved, the waist-shaped inner plate 2 is not in contact with the annular outer plate 1 at the position, the size precision of the waist-shaped inner plate is not required to be fine, the process requirement is reduced, and the processing is convenient. The distance from the hole wall of the long hole of the annular outer plate 1 to the outer side edge of the annular outer plate 1 is larger than 1mm and smaller than 2mm, the annular outer plate 1 is a closed strip-shaped plate, when the first and second

semicircular gaps

11 and 21 form an installation hole 3 and a small pipe or a small shaft which are not tightly inserted, the small shaft or the small shaft is easily separated from the installation hole 3, at the moment, the gap between the waist-shaped inner plate 2 and the annular outer plate 1 can be filled, the filler 4 can be steel leftover materials and the like, the outer annular plate 1 is propped open, the second semicircular gap 11 is forced to shrink towards the second semicircular gap 21, the pressure is more tightly pressed on the small pipe or the small shaft, the small pipe or the small shaft is locked in the installation hole 3, and the service life of the hinge can be prolonged.
