Abstract

The utility model relates to a greater pectoral muscle exerciser, which mainly comprises an arc-shaped top plate, two swing rod bodies and one more elastic body. A center of an outer part of the arc-shaped top plate is welded with an axle base. Two rotary pivoting axle sleeves positioned at back ends of the two swing rod bodies are arranged on the axle base. The two swing rod bodies are respectively pivotally connected and positioned on the axle base by an inserting pin. A front end of the swing rod body is provided with a gripping rod, and the middle and the back sections are fixedly provided with a sleeve sleeved with one or one more elastic bodies. The utility model can be pressed and positioned on abdomen for operation by the arc-shaped top plate and the two swing rod bodies have a good fixing implementing point under the condition of elastic stretching movement of the two swing rod bodies. The utility model can achieve smooth operation and movement, avoid the occurrence of sports injuries, and has no sloshing in operation and stability so as to realize the greater pectoral muscle exercising with correct implementation of tension.

Description

The chest expanding chest expander

Invention field

The utility model relates to a kind ofly to be made chest expanding, strong arm and makes the smooth chest expanding chest expander of belly, is meant that especially it has the application of force center of gravity of stable support, can not rock during operation, the tool steadiness, to reach the chest expanding exercise that can correctly implement tension force.

Background technology

Usually general desire is implemented chest expanding exercise, nothing more than being to use pulling force rope, it is provided with flexible members such as one or more than one stretch cords or spring between two hand draw rings, utilize the outer of both hands to draw during operation, can the tensile elasticity element, both arms have load forces by reaching, so that can be done chest expanding and to promote the arm beautiful curve opening when opening.

But owing to use pulling force rope, therefore it is to adopt in unsettled mode to operate, and can make the problem that generations is difficult to operate control on the application of force, if extracting words of the application of force really and rashly, even can cause athletic injury, therefore many consumers use to go up for traditional pulling force rope frightened relative more.

Summary of the invention

The utility model is the demand that realistic use can't be provided at pulling force rope, and the chest expanding chest expander that provides a kind of safe, easy operating to use, can utilize belly to be located, the one preferable fixedly point of application is arranged, reach operational motion smooth and easy with avoid producing athletic injury, to cater to user demand person, this chest expanding chest expander has the application of force center of gravity of stable support, can not rock during operation, the tool steadiness, can correctly implement the chest expanding exercise of tension force.

The purpose of this utility model realizes that by following technical proposals chest expanding chest expander of the present utility model consists predominantly of camber holding plate, two fork bodies and one or more elastomer; It is characterized in that: the outside centre solid welding of this camber holding plate has an axle bed, can be on this axle bed for each hinge axle sleeve of two fork bodies with its rear end, distinctly the pivot joint of two fork bodies is positioned on the axle bed by latch, this fork body front end is a holding rod, be installed with sleeve on the posterior segment, can be for being equipped with one or more elastomer; Can be positioned to operate on the belly by roof pressure by the camber holding plate, making to have a preferable fixedly point of application for two fork bodies doing elastic force opening and closing when action, reach operational motion smooth and easy with avoid producing athletic injury.

Another purpose of the present utility model is: the camber holding plate is provided with the maintenance linking tape of lopping backward, for when using the chest expanding chest expander, can encircle earlier by the maintenance linking tape and enclose in the belly place, so that adjustment is fixed on best use location to the arc holding plate, be beneficial to stable operation chest expanding chest expander simultaneously.

Description of drawings

Relevant structure of the present utility model, mode of operation and feature will be done further detailed description in conjunction with the accompanying drawings, make it is had more to be well understood to, wherein:

That shown in Figure 1 is the stereoscopic figure of the utility model chest expanding chest expander;

Shown in Figure 2 is the utility model chest expanding chest expander exploded perspective view;

Shown in Figure 3 is the utility model chest expanding chest expander user mode upper viewing view.

Shown in Figure 4 is another embodiment stereogram that the utility model chest expanding chest expander increases applied load power;

Shown in Figure 5 is that the utility model chest expanding chest expander shows actual user mode stereogram.Symbol description: 1 ... camber holding plate 11 ... cushion 12 ... axle bed 13 ... latch 2 ... fork body 21 ... holding rod 211 ... sheath 22 ... hinge axle sleeve 23 ... sleeve 231 ... nut 3 ... elastomer 4 ... the maintenance linking tape

The specific embodiment

See also the situation of Figure 1 and Figure 2; chest expanding chest expander of the present utility model includes camber holding plate 1; two fork bodies 2 and one or more elastomer 3; wherein camber holding plate 1 medial surface is provided with cushion 11; make camber holding plate 1 when contacting with belly; can improve comfortableness; the 1 outside centre solid welding of camber holding plate has an axle bed 12; can be on this axle bed 12 for two fork bodies, 2 each hinge axle sleeve 22 with its rear end; respectively the hinge axle sleeve 22 of two fork bodies 2 is coupling by latch 13 and is positioned on the axle bed 12; and fork body 2 also can be made fulcrum with latch 13 and pivoted by hinge axle sleeve 22; these fork body 2 front ends are to be the upwards holding rod 21 of bending; on holding rod 21 and be arranged with sheath 211; the power of reducing friction in the time of can protecting operation by human hand; and the position on fork body 2 posterior segments for being installed with sleeve 23, it can supply to be equipped with elastomer 3, after elastomer 3 is nested with the location; can screw togather by nut 231 and sleeve 23, be provided with fixedly elastomer 3 and be located between the two fork bodies 2.

See also Fig. 3 and Fig. 5 again, above-mentioned camber holding plate 1 is provided with the maintenance linking tape 4 of lopping backward, for when using the chest expanding chest expander, can encircle earlier by maintenance linking tape 4 and enclose in the belly place, be fixed on best use location so that camber holding plate 1 is adjusted, operator's both hands then can be gripped on respectively on the holding rod 21, utilize the strength of the outside Zhang Qi of both hands arm, can be out of shape by tensile elasticity body 3 effect that therefore reaches chest expanding, strong abdomen and can modify the arm curve.

In addition, see also Fig. 4, the chest expanding chest expander can be according to individual use habit, and is provided with one or more elastomer 3, so that the amount of exercise person of different load resistance to be provided.

According to the above description as can be known, chest expanding chest expander of the present utility model can utilize belly to be located, and a preferable fixedly point of application is arranged, and can be beneficial to operation, and the back of also needn't worrying to loose one's grip produces whole danger of dropping; Therefore, structural design of the present utility model is worked as specifically practicality, operation is light and safety.
