Abstract
The utility model discloses a weight lifting exerciser comprising a support and a weight lifting pole, wherein the support is provided with a cushion and a back cushion thereon, the support being provided with a rotating shaft which is fixedly provided with at least one disc, the disc being wounded with a rope, the end part of the rope being fixedly connected to the weight lifting pole, between the rotating shaft and the support being disposed a magnetorheological suspensions damper, between the disc and the support being provided a disc resetting-mechanism. By changing size of current through the excitation coil, the apparent viscosity of the magnetorheological suspensions in the gap can be changed so as to change damping force between the damping disc and the housing in realizing adjustment of exercising load on the weight lifting exerciser. The utility model has the advantages of simple operation, safety and reliability, continuous adjustment to load and large adjustment range and quick response. If an accident occurs, exercisers can relieve the pointing switch on the weight lifting pole, cut off the current, cancel damping force imposed on the weight lifting pole so as to protect exercisers and realize safety of the weight lifting exerciser.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of weight lifting fitness equipment, comprise support and weight lifting bar, described support is provided with cushion and back pad, described support is provided with rotating shaft, be set with at least one disk in the described rotating shaft, be wound with rope on the described disk, fixedly connected with described weight lifting bar in the end of described rope, be provided with magnetic rheological liquid damper between described rotating shaft and the described support, be provided with the disk resetting-mechanism between described disk and the described support.
Described magnetic rheological liquid damper comprises that sealing shroud is located at the housing in the described rotating shaft, described housing is fixedly installed on the described support, be provided with inner chamber in the described housing, be set with dampened disk in the described rotating shaft, described dampened disk is arranged in the described inner chamber, be provided with the gap that is used for the can magnetic flow liquid between described dampened disk and the described inner chamber, be provided with magnet exciting coil in the described inner chamber, be provided with every the magnetic copper band between described magnet exciting coil and the described dampened disk, described weight lifting bar is provided with point driving switch, controls by control circuit between described point driving switch and the described magnet exciting coil.
Described housing is provided with bosh and is used to seal the end cap of described bosh, and described end cap is provided with water inlet and the delivery port that communicates with described bosh.
Described disk resetting-mechanism is a back-moving spring, and an end of described back-moving spring is fixedly connected on the described disk, and the other end of described back-moving spring is fixedly connected on the described support.
Described disk is two and is fixedly connected on the two ends of described rotating shaft respectively that the end of described rope is fixedly connected on the end of described weight lifting bar.
The outer circumference surface of described disk is provided with around the rope groove, described rope around described in the rope groove.
Described cushion is fixedly installed on the described support, and described support is provided with support bar, and an end and the described cushion of described back pad are hinged, and the other end of described back pad leans against on the described support bar.
The upper end of described support is provided with the weight lifting bar fixed mount that is used to place the weight lifting bar.
Compared with prior art, the utility model has the advantages that owing to be provided with magnetic rheological liquid damper between rotating shaft and the support, by changing the size of current that feeds magnet exciting coil, can make that the apparent viscosity of magnetic flow liquid changes in the gap, thereby change the damping force between dampened disk and the housing, realize the weight lifting fitness equipment is taken exercise the adjusting of load, it is simple to operate, safe and reliable, and adjustable continuously to the adjusting of load, adjustable extent is big, response is fast; And if meet accident when taking exercise, the person taking exercise can decontrol the point driving switch that is positioned on the weight lifting bar, and turn-off current is cancelled the damping force that imposes on the weight lifting bar, plays protection person taking exercise's effect, and the security performance of fitness equipment is protected.
