Description

A kind of chest expander easy to use
Technical field
The utility model relates to a kind of sports equipment, particularly relates to a kind of chest expander easy to use.
Background technology
At present, a part for the daily production body-building of people has been become at sports equipment, in sports equipment, a kind of equipment of tempering arm strength that chest expander is commonly used, existing chest expander is varied, structure differs, but great majority are convenient all not in use, structure is also stable not, and easily damage, service life is short, and the chest expander of traditional stent-type, can not regulate the direction that force is taken exercise in use, the direction stretching that can only limit towards, so just brings certain trouble to the body-building group of different height.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of chest expander easy to use.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of chest expander easy to use, comprise at least one assistant support, rack-mount tension arm, the line rail groove be located on tension arm, be located at extend along its length in line rail groove guide rod, to install in online rail groove and the pulling block in described guide rod is inserted in bottom, be fixed on the hand draw ring on described pulling block and hold out against in described pulling block two ends and the exercise spring be enclosed within guide rod; The rear end of described tension arm is hingedly mounted on the top of support by hinge pin, the side, top of described support is provided with the limit guide rail of a semicircle shape, and the leaning to one side of described limit guide rail is provided with the arc guide barrel extended along self arcuate directions; The front bottom end of described tension arm is provided with the sliding shoe mating described arc guide barrel, and the two ends of described sliding shoe are provided with the adjusting bolt be movably hinged in described arc guide barrel, and described adjusting bolt has adjustment turning handle sliding shoe being locked in arc guide barrel surface.
Compared with prior art, the arm arm strength that exercise spring in the pulling block line of engagement rail groove that the utility model adopts can realize person taking exercise is taken exercise, structural stability is very high, the demand of different exercise crowds can be met, the arc guide barrel adopted, in conjunction with the structure of sliding shoe and adjusting bolt, can realize adjusting the direction of tension arm, meet the exercise of different height crowd, use convenient, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the chest expander easy to use that the utility model proposes, comprise support 1, rack-mount tension arm 2, the line rail groove 3 be located on tension arm 2, be located at extend along its length in line rail groove 3 guide rod 4, to install in online rail groove and the pulling block 5 in guide rod 4 is inserted in bottom, be fixed on the hand draw ring 12 on pulling block 5 and hold out against in pulling block two ends and be enclosed within the exercise spring 13 on guide rod 4.The quantity of support 1 is arranged according to actual needs, adopts connecting rod to fix between support and support, if adopt 2 assistant supports, such body builder may stand in the exercise that both arms are carried out in centre.
The coefficient of elasticity arranging length and temper spring 13 of line rail groove 3 coordinates, the two ends of pulling block 5 hold out against by the exercise spring on both sides.Arrange different exercise dynamics according to different exercise crowds, select different coefficient of elasticity to arrange and pull dynamics, the length arranging line rail groove can meet the exercise crowd of dissimilar arm exhibition.
The rear end of tension arm 2 is hingedly mounted on the top of support by hinge pin 6, hinge pin 6 can be fixed on a point of safes by tension arm 2, and tension arm can rotate with hinge pin 6, the side, top of support is provided with the limit guide rail 7 of a semicircle shape, the leaning to one side of limit guide rail 7 is provided with the arc guide barrel 8 extended along self arcuate directions, and the hinged installation site of hinge pin is the semicircle home position of limit guide rail 7.
The front bottom end of tension arm 2 is provided with the sliding shoe 9 of coupling arc guide barrel 8, the two ends of sliding shoe 9 are provided with the adjusting bolt 10 be movably hinged in arc guide barrel 8, the arc length of arc guide barrel 8 defines the rotational angle of tension arm, and rotational angle is be positive and negative 60 degree with limit guide rail 7 center line.
Adjusting bolt 10 has the adjustment turning handle 11 sliding shoe 9 being locked in arc guide barrel 8 surface.The bottom of adjusting bolt 10 is for snapping onto arc guide barrel 8 internal fixtion nut, and the grooved of arc guide barrel 8 is T-shaped, and adjusting bolt 10 regulates turning handle 11 through installing after sliding shoe 9, regulates turning handle 11 to screw the location that just can realize whole tension arm 2 like this.
Above-described embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the utility model patent and protection domain should be as the criterion with appended claims.
