Description
Technical field
The utility model belongs to the body-building apparatus field, relates in particular to a kind of improved chest expander.
Background technology
Along with the raising of the modern life, various body-building apparatus arise at the historic moment, and present chest expander generally adopts one group of spring to add the structure of handle, in use exists following shortcoming:
1, spring easily clips the skin of human body, produce the injury to human body, and the action that utilizes this equipment to do is few, and a lot of positions of human body can not get taking exercise;
2, the complex structure of steel strand exerciser, the manufacturing cost height;
3, steel strand exerciser is made of metal, thereby gets rusty easily in the use;
4, the deadweight of steel strand exerciser is bigger, and volume is also bigger, is unfavorable for carrying.
Summary of the invention
At the shortcoming that prior art exists, the utility model provides a kind of improved chest expander, can carry out various exercises by its people, to build up health, increases the health aesthetic feeling.
The technical solution adopted in the utility model is: a kind of improved chest expander mainly comprises elastic circular duct, draw ring, arming lanyard; It is characterized in that: the two ends of elastic circular duct are connected with draw ring respectively, are provided with perforation in the end of draw ring, and elastic circular duct is connected with draw ring by perforation; In elastic circular duct, be provided with arming lanyard.
Above-mentioned perforation is taper.
The similar isosceles trapezoid of above-mentioned draw ring shape.
Above-mentioned draw ring can also be circle or triangle or other shapes that is fit to.
The length of above-mentioned arming lanyard is longer than elastic circular duct.
The two ends of above-mentioned arming lanyard are passed the centre bore of the fixing plug of stay cord respectively and are fixed.
The fixing plug of stay cord is cone-shaped plunger, is located at the junction of interior elastic circular duct of elastic circular duct and draw ring, and its tapered direction is consistent with cone-type piercer.
Also be provided with in the junction of elastic circular duct and draw ring and be connected sheath; Interlude at elastic circular duct also is provided with the pipe sheath.
Advantage that the utlity model has and effect:
1, the utility model is simple in structure, low cost of manufacture, thereby reduced cost of manufacture and use cost;
2, the utility model in use people can arbitrarily use, safe and reliable, can effectively take exercise each position of health;
3, the utility model does not produce rust staining, thereby can reach the effect of environmental protection.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the improved chest expander of the utility model mainly comprises elastic circular duct 1, draw ring 2, arming lanyard 3, the fixing plug 4 of stay cord, connects sheath 5 and pipe sheath 6; Wherein, the two ends of elastic circular duct 1 are connected with draw ring 2 respectively, and the similar isosceles trapezoid of draw ring 2 shapes is provided with cone-type piercer in the end of draw ring 2, and elastic circular duct 1 is connected with draw ring 2 by perforation; Above-mentioned draw ring 2 can also be circle or triangle or other shapes that is fit to.
Can protect human body during for elastic circular duct 1 breakage in use, be provided with arming lanyard 3 in elastic circular duct 1, the length of arming lanyard 3 is longer than elastic circular duct;
The two ends of arming lanyard 3 are passed the centre bore of the fixing plug 4 of stay cord respectively and are fixed; The fixing plug 4 of stay cord is a cone-shaped plunger, is located at the junction of interior elastic circular duct 1 of elastic circular duct and draw ring 2, and its tapered direction and cone-type piercer are consistent;
Because it is more that elastic circular duct connects the number of times that bends when draw ring is in use, be the intensity that strengthens the junction, protection junction elastic circular duct 1 is not fractureed, and also is provided with in the junction of elastic circular duct 1 and draw ring 2 to be connected sheath 5; In order to adapt to the use in outdoor place, prolong the service life of elastic circular duct 1, also be provided with pipe sheath 6 at the interlude of elastic circular duct 1.
In sum, be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
