Description

Chest-developer

The utility model relates to the elevator draw gear of lifting transport field, particularly about a kind of chest expander.

In the prior art, it is to adopt chain type transmission mechanism that bottle gouard moved by hands hangs, exist folding and unfolding slowly, use cumbersome, be not easy to carry, shortcoming such as cost height.

The purpose of this utility model provide a kind ofly be used for that shipping goods stay cord envelope is tight, vehicle is sliding falls into the dilatory chest expander that the advance and retreat operation is rapid, simple in structure, cost is low.

Technical solution of the present utility model is: a kind of chest expander, comprise pulley 9, last drop hanger 4, following drop hanger 10, cable wire 8 and winding drum 18, it is characterized in that: go up the lower end and the keel frame 12 of drop hanger 4 and go up the upper end of cutting with scissors ear 13 and join, the lower end of last hinge ear 13 and the outside of housing 5 join, housing 5 joins with housing 11, the upper end of housing 11 is provided with power-transfer clutch 3, be provided with the satellite gear transmission device 6 that joins with keel frame 12 in the housing 11, be provided with the winding drum 18 that the mouth with satellite gear transmission device 6 joins in the housing 5, one end and the winding drum 18 of cable wire 8 join, the other end is connected to can separate pin 7, can separate pin 7 joins with the lower end that keel frame 12 reaches following hinge ear 14, cut with scissors the upper end of ear 14 and the outside of housing 5 down and join, an end of rocking bar 2 and the input end of satellite gear transmission device 6 join, the other end and handle 1 join.

Be provided with the input end of bent axle 17 in the centre hole of the cycloid inner gear 15 of described satellite gear transmission device 6, the mouth of bent axle 17 is connected to cycloid in planet wheel 16, the external tooth of cycloid in planet wheel 16 is meshed with the internal tooth of cycloid inner gear 15, a pin end of 20 is inserted in the uniform hole on the cycloid in planet wheel 16, the other end and load are turned 19 joins, load is turned and 19 is respectively equipped with bearing 21 with the joint of keel frame 12 and housing 5, and turn 19 axle of load is affixed with the endoporus of winding drum 18.

The utility model is compared with prior art to have: compact conformation, can realize step-less adjustment, free to advance or retreat, force increasing ratio is big, easy to carry, advantage such as cost is low.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the scheme drawing of the cutaway view of satellite gear transmission device 6 of the present utility model.
