Description

A kind of chest expander of adjustable exercise
Technical field
The utility model relates to a kind of physical fitness equipment, particularly relates to a kind of chest expander of adjustable exercise.
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, easy damage, service life is short, and the chest expander of traditional stent-type, the direction that force is taken exercise can not be regulated in use, the direction stretching that can only limit towards one, so just certain trouble is brought to the body-building group of different height, and suitable adjustment can not be carried out for the crowd of different height arms exhibition, very large trouble is brought to person taking exercise.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, proposes a kind of chest expander of adjustable exercise.
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 of adjustable exercise, comprise an assistant support, be laterally hinged with rack-mount tension arm, be located at tension arm arm with it and along the extended line rail groove in arm body length direction, be located at line rail groove groove in and in the guide rod extended along its length, Matching installation online rail groove and middle part run through and be enclosed within pulling block on described guide rod and regulating block; Be connected to the exercise spring be enclosed within guide rod between described pulling block and regulating block, the two ends of described pulling block are provided with a pair and pull handle, and the middle part of described regulating block is provided with the elasticity bolt for regulating location, and the head of described elasticity bolt is provided with turning handle; Be hingedly mounted on support by hinged pin in the middle part of the back side of described tension arm, described frame upper side is also provided with the limit guide rail of an arc-shaped, the rail of described limit guide rail has the arc guide barrel extended along self arcuate directions with it, and the articulated position of described tension arm and support is positioned at the home position of arc guide barrel circular arc; 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, described adjusting bolt has the adjustment turning handle be locked in by sliding shoe on arc guide barrel; The opposite side of described support is provided with the chair lift structure of sitting up straight for person taking exercise, described chair lift structure comprises vertical fixing lifting carrier bar, be arranged on the cushion of the expansion link upper end of lifting carrier bar and for regulating the foot-operated starter of adjustable height, and the cross bar of described support is provided with hinged pedal.
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, the regulating block arranged can by moving left and right the position fixed ends regulating and regulate and temper spring, and then the distance that can regulate chair lift and take exercise between spring fixed end, and then crowd's needs of dissimilar arm exhibition can be met, the exercise state of The Gift of Being the Best You Can Be.The arc guide barrel of further employing, in conjunction with the structure of sliding shoe and adjusting bolt, can realize adjusting the direction of tension arm, then by combining adjustment chair lift structure, meet the exercise of different height crowd, and structural stability is very high, 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 of the adjustable exercise that the utility model proposes, comprise an assistant support 1, be laterally hinged with rack-mount tension arm 2, be located at tension arm 2 arm with it and along the extended line rail groove 3 in arm body length direction, be located at line rail groove 3 groove in and in the guide rod 4 extended along its length, Matching installation online rail groove and middle part run through and be enclosed within pulling block 5 on described guide rod 4 and regulating block 6.
The exercise spring 7 be enclosed within guide rod 4 is connected between pulling block 5 and regulating block 6, the two ends of pulling block 5 are provided with and pull handle 8 and a hand draw ring 20 be arranged on pulling block 5 for a pair, the middle part of regulating block 6 is provided with the elasticity bolt 9 for regulating location, and the head of elasticity bolt 9 is provided with turning handle 10.
Wherein temper spring 7 and 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.And exercise spring 7 is arranged on regulating block due to stiff end, so can carry out careful adjustment according to the dissimilar arm exhibition of crowd, is adjusted to exercise state the most comfortable.
Be hingedly mounted on support 1 by hinged pin in the middle part of the back side of tension arm 2, frame upper side is also provided with the limit guide rail 11 of an arc-shaped, the rail of limit guide rail 11 has the arc guide barrel 12 extended along self arcuate directions with it, and tension arm 2 is positioned at the home position of arc guide barrel 12 circular arc with the articulated position of support.The front bottom end of tension arm 2 is provided with the sliding shoe 13 mating described arc guide barrel 12, and the two ends of sliding shoe 13 are provided with the adjusting bolt 14 be movably hinged in arc guide barrel 12, adjusting bolt 14 has the adjustment turning handle 15 be locked in by sliding shoe 13 on arc guide barrel 12.The bottom of adjusting bolt is for snapping onto arc guide barrel internal fixtion nut, and the grooved of arc guide barrel is T-shaped, and adjusting bolt regulates turning handle through installing after sliding shoe, regulates turning handle to screw the location that just can realize whole tension arm like this.
The opposite side of support 1 is provided with the chair lift structure of sitting up straight for person taking exercise, chair lift structure comprises vertical fixing lifting carrier bar 16, be arranged on the cushion 17 of the expansion link upper end of lifting carrier bar 16 and for regulating the foot-operated starter 18 of adjustable height, and the cross bar of support is provided with hinged pedal 19.
When the use of reality, person taking exercise regulates the height of cushion 17 according to actual needs, the incline direction regulating tension arm is being needed according to the exercise of oneself, after having adjusted, can be sitting on cushion, both hands are held up and down and are pulled handle 8 to perform physical exercise, or pull hand draw ring 12 to perform physical exercise, and wherein regulating block can move left and right, this makes it possible to the distance regulating chair lift and take exercise between spring fixed end, and then crowd's needs of dissimilar arm exhibition can be met, the exercise state of The Gift of Being the Best You Can Be.
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.
