Abstract

The utility model relates to a novel lever hoist which comprises a long shaft, a spline hole gear, an upper lifting hook component, a left-right wall component, a guide wheel, a chain-blocking plate, pawls, a brake, ratchet wheels, a friction plate, a cam, a shell, a lifting chain, a lower lifting hook component, a limit ring component, a locknut and a chain wheel shaft. The upper lifting hook component is fixed with the left-right wall component through a hook beam; the left-right wall component is fixed with the shell through a support bar; the lower lifting hook component is fixed at one end of the lifting chain; the guide wheel is arranged at one side of the chain wheel shaft; the chain-blocking plate is arranged on the left-right wall component at the lower part of the chain wheel shaft; the ratchet wheels are sequentially arranged at the right end of the long shaft; the right ends of the ratchet wheels are connected with a handle; the handle is sleeved outside a reversing ratchet wheel; the left and right ends of the handle are respectively movably connected with a hand wheel and a ratchet wheel housing; the brake is arranged in a wrench; the friction plate is arranged on a brake seat of the brake; the ratchet wheel housing is arranged on the right plane of a rack; and a chain guide frame and the chain wheel shaft are arranged in the middle of the rack. The novel lever hoist is characterized in that the position of the chain wheel shaft and the long shaft is consistent with the direction of the chain.

Description

Novel Lever Blocks

Technical field

The utility model relates to cucurbit, particularly be a kind of novel Lever Blocks.

Background technology

The weight of the general general lifting of hand chain lever hoist is little in the market, existing novel small-sized cucurbit is mainly to comprise with lower member: the shifting block direction reverser, handwheel, spanner, the commutation ratchet, stop mechanism, the ratchet case, frame is hung parts, chain guides, sprocket shaft is formed, and it is that the right-hand member of sprocket shaft is equipped with the commutation ratchet successively, and commutation ratchet right-hand member is connected with handwheel, spanner is enclosed within the outside of commutation ratchet, its left side, right two ends flexibly connect with handwheel and ratchet case respectively, and the shifting block direction reverser is contained in the spanner the inside, and the ratchet case is installed in the plane, right side of frame, chain guides, sprocket shaft is installed in the centre of frame, and forms a secondary hoist mechanism that rotates with stop mechanism and commutation ratchet.It is not provided with brake equipment, just by the reversing sense braking of ratchet, makes and uses ratchet wearing and tearing, service life to shorten for a long time.

The utility model content

In order to overcome above-mentioned technical defective, the utility model provides novel Lever Blocks.

To achieve these goals, the utility model adopts following technical scheme:

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, hoisting chain, 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, on the left and right sides, the bottom wall assembly of sprocket shaft the retaining carrier bar is set, 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, and the ratchet case is installed in the plane, right side of frame, chain guides, sprocket shaft is installed in the centre of frame, and forms a secondary hoist mechanism that rotates with stop mechanism and commutation ratchet; It is characterized in that: the position of sprocket shaft and major axis causes with the direction of chain is a pair of.

The utility model is rational in infrastructure, and the locality of sprocket shaft and major axis is a pair of to be caused, laborsaving.
