Description
Technical field:
The utility model relates to cucurbit, particularly be a kind of novel Lever Blocks.
Background technology
The chain nest of general hand chain lever hoist all is to adopt 4 chain nests in the market, adopts the profile of four chain nest chain hoist wheels to become heavy, and adopts the Lever Blocks of 4 chain nests, also can become heavy on the profile of cucurbit, and volume can increase a lot.Major axis can be crossed chain hoist wheel, and the rotation by major axis drives chain hoist wheel, drives chain by chain hoist wheel again, thereby weight is promoted up and descends.
Summary of the invention
In order to reduce the volume of material and cucurbit, the utility model purpose provides a kind of novel Lever Blocks.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel Lever Blocks, it is mainly to comprise: major axis with lower member, the splined hole gear, the hook assembly, left and right sides wall assembly, guide wheel, the retaining carrier bar, ratchet, drg, ratchet, Friction disk, cam, shell, play the vertical chain bar, following hook assembly, end the lock ring assembly, jam nut, sprocket shaft is formed, its hook assembly is fixed by hook beam and left and right sides wall assembly, left and right sides wall assembly is fixed by strut bar and shell, following hook assembly is fixed on an end of hoisting chain, one side of sprocket shaft is provided with guide wheel, the retaining chain is set on the left and right sides, the bottom wall assembly of sprocket shaft to be pulled, the right-hand member of major axis is equipped with ratchet successively, the ratchet right-hand member is connected with handle, taper knob is in the outside of commutation ratchet, its left side, right two ends flexibly connect with handwheel and ratchet case respectively, drg is contained in the spanner the inside, on the drg seat of drg Friction disk is installed, the ratchet case is installed in the plane, right side of frame, chain guides, sprocket shaft is installed in the centre of frame, and form a secondary hoist mechanism that rotates with stop mechanism and commutation ratchet, it is characterized in that: the chain nest is set on the sprocket shaft.
The utility model is rational in infrastructure, because chain nest and sprocket shaft one can not become flexible after long-time the use yet.
