Disclosure of Invention

The utility model aims at: in order to overcome the defects of the prior art, the utility model provides a swing chain is hung and is detained, simple to operate, and simple to use can change when damaging, and is also stronger with low costs practicality.

The utility model discloses a swing chain is hung and is buckled, its characterized in that: including the main shaft body, be equipped with screw thread section an on the main shaft body along its length direction in proper order, support clamp plate and mounting hole, be equipped with on the screw thread section a rather than the lock nut of looks adaptation, lock nut overlaps and establishes on screw thread section an, wears to be equipped with the pivot in the mounting hole, and the pivot is rotated and is set up in the mounting hole, still U type pole in the pivot, and U type pole both ends are equipped with the hinge hole, and the pivot is worn to establish and is articulated downthehole.

Adopt above-mentioned technical scheme, can install the mobile jib body plate body or on the body of rod, lock nut can realize the effect of locking with the cooperation that supports the clamp plate, screw thread section a and lock nut's cooperation can realize the function of auto-lock when using, it is not hard up to prevent when using, the pivot of can being convenient for of mounting hole is installed, the installation and the binding of chain can be convenient for to the U type pole, can change when each spare part warp or damage, it is more convenient when making the maintenance, required cost is also lower, it is also more convenient when installing, need not install with the help of other instruments.

The utility model discloses a further setting again: an internal thread is arranged in one of the hinge holes of the U-shaped rod, and a thread section b matched with the internal thread is arranged on the rotating shaft.

Adopt above-mentioned further setting again, can prevent that U type pole from sliding along pivot length when using for it is more stable and safe when using.

The utility model discloses a further setting again: the one end of pivot is equipped with the handle, and screw thread section b sets up the other end at the pivot, is equipped with the boss on the handle, and the cover is equipped with stop nut on the screw thread section b, and the boss is located one side of U type pole, and stop nut is located the opposite side of U type pole.

Adopt above-mentioned further setting again, restriction U type pole that can be further breaks away from the pivot for it is more stable when using, and factor of safety is higher

The utility model discloses a further setting: the bearing is arranged in the mounting hole, a shaft hole is arranged in the bearing, and the rotating shaft penetrates through the shaft hole.

Adopt above-mentioned further setting, can reduce the frictional force of pivot in the pivoted for the effect is better when the swing is used.

The utility model discloses a further setting: the pressing plate is provided with a stand column.

Adopt above-mentioned further setting, can prevent that the main rod body from rotating along its own circumference for the effect is better when using.
