Abstract
The utility model relates to a handle pulling cucurbit for lifting weight, which includes a shell, a chain wheel axle, a chain wheel, a handle component, a braking component, a direction switching pawl which is articulated with a direction switching ratchet of the chain wheel. The chain wheel axle is also integrated with the chain wheel; the chain wheel axle is connected with a left and a right steel casings; the utility model is easy to assemble and has long service life. The direction switching ratchet and the direction switching pawl are arranged in a '8'-shaped hole. The structure is characterized by small volume, novel appearance and convenient application.
Description
Technical field the utility model relates to mechanical transmissioning technology, specifically is the Lever Blocks that promotes a kind of ratchet drive friction braking of weight.
Existing sprocket shaft of Lever Blocks of background technology and being connected of wallboard, easy to wear, effort gas is manipulated in the very fast increase in gap, and the life-span is short.The Handleset assembling is time-consuming, is not durable.
The problem that summary of the invention exists original Lever Blocks structure design, we provide the utility model can solve a kind of wear-resistant of above-mentioned defective, the Lever Blocks of assembling handling ease.
The technical design scheme of the utility model Lever Blocks is described as follows: it includes shell, sprocket shaft, sprocket wheel, Handleset, brake assemblies, Handleset has reversing handle, commutation ratchet, commutation pawl axis and handle, stop mechanism has Brake Block, stop-off nut, Friction disk, ratchet; The commutation ratchet of Handleset connects with the commutation ratchet engaged that is socketed in one of sprocket shaft, commutation ratchet and commutation ratchet are installed in " 8 " word hole on the handle head, sprocket shaft is cast as one with sprocket wheel, and the one head connects left and right steel bushing, and left and right steel bushing connects left and right wallboard respectively.
Compact conformation of the present utility model is simple, and sprocket shaft is linked as one with sprocket wheel, and its head end connects left and right steel bushing, reduces work hours, and cost improves service life.The handle head end is designed to " 8 " word hole, attaching commutation ratchet and commutation ratchet, and volume is little, and is easy to assembly, and dexterous, attractive in appearance.
The drawing explanation
Fig. 1 is the utility model topology view;
Fig. 2 is the handle arrangement view.
1-left side steel bushing, the right steel bushing of 2-, 3-" 8 " block, the 4-ratchet that commutates, the 5-handwheel, 6-self lock nut, 7-sprocket shaft, the 8-ratchet that commutates, the 9-pawl axis that commutates, the 10-reversing handle, 11-handle, 12-shell I, 13-bonnet, 14-left side wallboard, the right wallboard of 15-, 16-stop-off nut, 17-Friction disk, the 18-ratchet, 19-drg seat, 20-drg seat spring, 21-shell II, 22-" 8 " word hole, 23-macropore, 24-aperture, 25-sprocket wheel.
Details are as follows to summary of the invention with embodiment with reference to the accompanying drawings now for the specific embodiment: the commutation ratchet 8 of Handleset of the present utility model is packed in the aperture 24 in handle 11 head ends " 8 " word hole 22, captives joint with handle 11 and reversing handle 10 through commutation pawl axis 9.The commutation ratchet 4 of stop mechanism of the present utility model is installed in the macropore 23 in handle 11 head ends " 8 " word hole 22, bonnet 13 attachment screws that are " 8 " block are " 8 " word hole 22 of handle 11 in succession, commutation ratchet 4 connects with stop-off nut 16 sleeve removables, stop-off nut 16 is threaded with sprocket shaft 7, drg seat 19 connects with sprocket shaft 7 splines, the commutation ratchet 8 that links to each other with reversing handle 10 has a left side, right ratchet, plate move to handle 10 supreme raise-positions put make commutation ratchet 8 left pawl with the engagement of commutation ratchet 4, operating handle 11 crank motions, commutation ratchet 4 clockwise rotates, be wrenched stop-off nut 16, overcome drg seat spring 20 elastic force, compress the Friction disk 17 on drg seat 19 steps, ratchet 18 and drg seat 19, sprocket shaft 7 head ends are with a left side, right steel bushing 1 and 2 gaps flexibly connect a left side, right steel bushing 1 and 2 is riveted a left side respectively, right wall newspaper 14 and 15, drg seat 19 drive sprocket shaft 7 and sprocket wheel 25 rotates, hoisting chain is along the running of the chain nest of sprocket wheel 25 central authorities, on carry weight.Reversing handle 10 is to lowering position, commutation ratchet 8 right ratchets are with 4 engagements of commutation ratchet, commutation ratchet 4 rotates counterclockwise, under the effect of drg seat spring 20, Friction disk 17, ratchet 18 and drg seat 19 will unclamp a gap, hoisting chain is under the weight effect, and sprocket wheel 25 and sprocket shaft 7 rotate counterclockwise, and weight descends.
The shell of this Lever Blocks has front casing II21 and shell I12, and shell II21 is fixedly connected on left wallboard 14, and shell I12 is fixedly connected on right wallboard 15, handwheel 5 connects with commutation ratchet 8 waist shaped holes, tighten by self lock nut 6, when the room, be convenient to regulate down the position of suspension hook.
Claims (2)
1, a kind of Lever Blocks, it includes shell, sprocket shaft, sprocket wheel, Handleset, brake assemblies, the commutation ratchet of Handleset connects with the commutation ratchet engaged of sprocket shaft one end, the drg seat connects with the sprocket shaft spline, it is characterized in that sprocket shaft (7) one ends are connected with (2) with left and right steel bushing (1), sprocket wheel (25) is cast as one with sprocket shaft (7), and commutation ratchet (8) and commutation ratchet (4) are installed in " 8 " word hole of handle head end.
