Abstract
A kind of safe arm exerciser, belongs to health and fitness facilities technical field, more particularly to a kind of chest-developer, including safety belt, handle, spring, chock, rubber sleeve.One layer of rubber sleeve is superscribed among chest-developer spring, rubber sleeve is rounded, can be by one section of bag among spring in inside, internal fixed wedge on rubber sleeve, chock is between rubber sleeve and spring, chock tip is towards spring, the other end is fixed on rubber sleeve, when using chest-developer, there is gap among spring between two rings of outside, chock enters between ring spring under the elastic force of rubber sleeve, pressure after loosing one's grip between two ring of spring is shared to chock, chock can slowly be extruded and restored to the original state by spring, so will not rebound moment, can guarantee that the safety of user.
Description
Technical field
A kind of safe arm exerciser, belongs to health and fitness facilities technical field, more particularly to a kind of chest-developer.
Background technology
Chest-developer small volume and less weight, is the fitness equipment that many people can select, but traditional chest-developer is when in use
There is a very big bounce, also can be by even if safety belt is taken in wrist once rubber sleeve can cause actual bodily harm to user
Wound, wrist also suffer from injury.
The content of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned present situation, a kind of safe arm exerciser is invented.
A kind of safe arm exerciser, including safety belt, handle, spring, chock, rubber sleeve.
One layer of rubber sleeve is superscribed among chest-developer spring, rubber sleeve is rounded, and one section of bag among spring can exist
Inside, internal fixed wedge on rubber sleeve, chock between rubber sleeve and spring, towards spring, the other end fix by chock tip
On rubber sleeve.
Chock is substantially in coniform, and circular cone faces outwardly somewhat prominent.
When not in use, chest-developer spring normally compresses, and does not have gap between each ring, and chock passes through rubber outside spring
Gum cover is fixed, and when using chest-developer, most middle spring outwards separate, and chock enters bullet under the elastic force effect of rubber sleeve
Spring, acts between two ring of spring, and after user looses one's grip, chock is slowly extruded spring, chest-developer by spring under force
It will not instantaneously eject again, ensure user's safety, the circular cone of chock, which faces outwardly, somewhat to be protruded, when spring deformation is maximum,
Pressure between two rings is also the largest, smaller with the tangential angle of spring contact point on chock, by point of chock extrusion spring
Power is also smaller, and when spring is close to when recovery, the pressure between two rings is smaller, on chock with the tangential angle of spring contact point
Larger, the component of chock extrusion spring is also larger, this design can ensure that the speed that chock is extruded is not too fast, while also can
Guarantee to extrude completely.
, there are the power that chock shares springback in a kind of safe arm exerciser of the present invention, when use, it is ensured that user will not
It is injured.
Brief description of the drawings
Fig. 1 is a kind of safe arm exerciser overall structure figure of the present invention；Fig. 2 is a kind of safe arm exerciser cleat structure of the present invention
Figure.
In figure：1- safety belts, 2- handles, 3- springs, 4- chocks, 5- rubber sleeves.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：A kind of safe arm exerciser, including safety belt 1, handle 2, bullet
Spring 3, chock 4, rubber sleeve 5.
One layer of rubber sleeve 5 is superscribed among chest-developer spring 3, rubber sleeve 5 is rounded, can be by one section among spring 3
Bag internal fixed wedge 4 on inside, rubber sleeve 5, chock 4 between rubber sleeve 5 and spring 3,4 tip of chock towards spring,
The other end is fixed on rubber sleeve 5.Chock 4 is substantially in coniform, and circular cone faces outwardly somewhat prominent.
When not in use, chest-developer spring 3 normally compresses, and does not have gap between each ring, and chock 4 passes through outside spring 3
Rubber sleeve 5 is fixed, and when using chest-developer, the most middle outside of spring 3 separates, and chock 4 is under the elastic force effect of rubber sleeve 5
Into spring 3, act between 3 liang of rings of spring, after user looses one's grip, chock 4 is slowly extruded bullet by spring 3 under force
Spring 3, chest-developer will not be ejected instantaneously again, ensure user's safety, and the circular cone of chock 4, which faces outwardly, somewhat to be protruded, in 3 deformation of spring
When maximum, the pressure between two rings is also the largest, smaller with the tangential angle of 3 contact point of spring on chock 4, by chock
The component of 4 extrusion springs 3 is also smaller, and when spring 3 is close to when recovery, the pressure between two rings is smaller, on chock 4 with spring
The tangential angle of 3 contact points is larger, and chock 4 extruded to the component of spring 3 is also larger, this design can ensure that chock 4 is extruded
Speed it is not too fast, while also can guarantee that and can extrude completely.
, there are the power that chock 4 shares springback in a kind of safe arm exerciser of the present invention, when use, it is ensured that user will not
It is injured.
