Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, hand winch described in the utility model includes ropewinder, crane arm, bearing holder (housing, cover) 4 and bottom
Seat 10, bearing holder (housing, cover) 4, which is sleeved on, to be fixed on the axis at 10 center of base, and ropewinder and crane arm are each attached on bearing holder (housing, cover) 4.Ropewinder
Including stent, reel, gear wheel, pinion gear and crank 3, reel, gear wheel, pinion gear and crank 3 are arranged on stent, branch
Frame is fixedly connected with bearing holder (housing, cover) 4.Crank 3 is coaxial with pinion gear, and gear wheel is coaxial with reel, and pinion gear is meshed with gear wheel,
Cable takeup is on reel.When rotating crank 3 manually, the shaft being fixedly connected with crank 3 rotates, so as to drive pinion gear to turn
It is dynamic.By between pinion gear and gear wheel engaging drive bull gear drive, gear wheel drive be secured to connection shaft and
The spool turns being fixed in shaft, it is achieved thereby that the withdrawing rope of reel.
Crane arm is formed by fixing crane arm 2 and telescopic boom 1, and one end of fixed crane arm 2 is fixed with bearing holder (housing, cover) 4 to be connected
Connecing, the other end of fixed crane arm 2 is connected with telescopic boom 1, and telescopic boom 1 can be elastic along fixed crane arm 2,
So as to be adjusted to the length of crane arm.
10 top surface of base is fixedly arranged in the middle of axis, and bearing holder (housing, cover) 4 is sleeved on axis, and bearing holder (housing, cover) 4 can be rotated along axis, so that
Crane arm is driven to rotate.Base 10 is equipped with several screw rods 6, and screw rod 6 is threadedly coupled with a side of base 10, screw rod 6 and bottom
The both sides of 10 junctions of seat set nut 7 respectively, and nut 7 is fixedly connected with base 10.Nut 7 plays guiding role.With
