Abstract
The utility model provides a rope wheel reversing mechanism of a body building machine and belongs to body building equipment. The rope wheel reversing mechanism comprises a main shaft installed on a machine frame of the body building machine, a shaft sleeve installed on the main shaft and a rope wheel fixedly installed on the shaft sleeve, wherein a reversing frame is also installed on the shaft sleeve and comprises left and right symmetrical frame arms arranged at two sides of the shaft sleeve in a sleeved manner, screw shafts and nuts installed in holes at front ends of the left and right frame arms, and pulleys sleeved on the screw shafts; left and right limit columns are also symmetrically fixed at two sides of the rope wheel and below the left and right frame arms; and pulley covers are installed on the screw shafts and are located on the outer surfaces of the pulleys. As rope wheel reversing mechanisms are arranged at two sides of the rope wheel and are in bilateral symmetry, the both sides bear the force, and the rope wheel and the reversing frame receive balanced forces; therefore, the rope wheel reversing mechanism is not easy to damage, and the service life of the rope wheel reversing mechanism is greatly prolonged; moreover, the rope wheel reversing mechanism can be widely applied in a cable-towed counterweight iron type body building machine.
Description
Technical field
The utility model belongs to the body-building apparatus technical field, more particularly relates to the design improvement of the rope sheave changement of body exercising machine.
Background technology
The rope sheave changement is the common mechanism in the cable traction balance weight iron formula body exercising machine.Rope sheave generally is used for pull line, and handle then is used to drive rope sheave.But in traditional rope sheave changement, the reversing gear bracket that is fixed in the limited post on the rope sheave and is supporting angle pulley all is installed on a side of rope sheave, thereby one-sided stressed.The rope sheave of this structure and reversing gear bracket discontinuity equalization, thus very easily damage, and then reduce its service life.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of rope sheave changement of body exercising machine is provided.It is installed on the both sides of rope sheave, left-right symmetry, thereby bilateral is stressed, and rope sheave and reversing gear bracket stress equalization, so not fragile, prolong service life greatly.
In order to achieve the above object, the utility model comprises the main shaft that is installed on the body exercising machine frame, is installed in axle sleeve on the main shaft, is fixedly mounted on the rope sheave on the axle sleeve.Reversing gear bracket also is installed on the axle sleeve.Reversing gear bracket comprises the symmetrical boom that is sleeved on the axle sleeve both sides, be installed in screw axis and nut in the boom front aperture of the left and right sides, be sleeved on the pulley on the screw axis.The rope sheave both sides are positioned at the following also symmetry of left and right sides boom and are fixing left and right sides limited post.
The pulley cover is installed on the screw axis, and the pulley cover is positioned at the pulley outside.
The all symmetry installations of left and right sides boom, pulley and pulley cover and left and right sides limited post, stress equalization, so not fragile, prolong service life greatly.
Task of the present utility model comes to this and finishes.
The utility model is installed on the both sides of rope sheave, left-right symmetry, thereby bilateral is stressed, and rope sheave and reversing gear bracket stress equalization, so not fragile, prolong service life greatly.It can be widely used in the cable traction balance weight iron formula body exercising machine.
Description of drawings
Fig. 1 is the schematic diagram of rope sheave changement.
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
Embodiment 1.A kind of rope sheave changement of body exercising machine is as Fig. 1～shown in Figure 2.It comprises the main shaft that is installed on the body exercising machine frame 1, be installed in axle sleeve 2 on the main shaft, be fixedly mounted on the rope sheave 3 on the axle sleeve 2.Reversing gear bracket also is installed on the axle sleeve 2.Reversing gear bracket comprise with the hole 13 of end be sleeved on axle sleeve 2 both sides symmetrical boom 4, be installed in screw axis 6 and nut in left and right sides boom 4 front aperture 5, be sleeved on the pulley 7 on the screw axis 6.Rope sheave 3 both sides are positioned at the following also symmetry of left and right sides boom 4 and are fixing left and right sides limited post 8.Cable wire 9 is walked around pulley 7, is fastened in the tube bank 11 that is fixed on the rope sheave 3 to press closer screw 10.Reversing gear bracket 14 can rotate relative to rope sheave 3.
Pulley cover 12 is installed on the screw axis 6, and pulley cover 12 is positioned at the outside of pulley 7.Pulley cover 12 can prevent dust, and can avoid injuring human body.
Left and right sides boom 4, pulley 7 and pulley cover 12 and all symmetry installations of left and right sides limited post 8, stress equalization, so not fragile, prolong service life greatly.
Embodiment 1 is installed on the both sides of rope sheave, left-right symmetry, thereby bilateral is stressed, and rope sheave and reversing gear bracket stress equalization, so not fragile, prolong service life greatly.It can be widely used in the cable traction balance weight iron formula body exercising machine.
Claims (2)
1. the rope sheave changement of a body exercising machine, comprise the main shaft that is installed on the body exercising machine frame, be installed in axle sleeve on the main shaft, be fixedly mounted on the rope sheave on the axle sleeve, it is characterized in that also being installed with on the axle sleeve reversing gear bracket, reversing gear bracket comprises the symmetrical boom that is sleeved on the axle sleeve both sides, be installed in screw axis and nut in the boom front aperture of the left and right sides, be sleeved on the pulley on the screw axis, and the rope sheave both sides are positioned at the following also symmetry of left and right sides boom and are fixing left and right sides limited post.
