Description

Chest muscle exerciser

Technical field

The utility model relates to a kind of chest muscle exerciser, belongs to body-building equipment technical field.

Background technology

At present, in society, the people of body-building is increasing, and body-building has become a kind of popular, and much fitness enthusiasts are thought, chest muscle is a standard whether boy student is strong of proof, so temper chest muscle, is a kind of exercise that welcome by boy student.The mode that people temper chest muscle generally adopts push-up, barbell, chest expander or large-scale apparatus to perform physical exercise.Often easily injured during by push-up, barbell or chest expander training, chest expander especially, in training process, operate miss is easy to user to injure, and easily clamps hair, and this tempers chest muscle and has brought a lot of unnecessary troubles.Although large-scale apparatus safety, cost is high, is not suitable for general population and uses.

Summary of the invention

The deficiency existing in order to overcome prior art, the utility model provides a kind of chest muscle exerciser, utilizes this exerciser to perform physical exercise easily anywhere, safe and practical.

The utility model solves the technical scheme that its technical problem adopts: a kind of chest muscle exerciser is comprised of handle, spacing spring column, extension bar, arm frame, iron axle, Connection Block one, spring, hinge, shoulder belt, back backup plate and Connection Block two.Back backup plate is the structure centre of whole chest muscle exerciser, and back backup plate profile is similar to M, and centre is the corresponding vertebral location of high spot slightly.Shoulder belt two ends are fixed on the top and bottom of back backup plate, and shoulder belt is in back backup plate inner side, the corresponding shoulder position of two shoulder belts, two top ends of the V part in the middle of similar M type.Two lower ends of the similar M type of back backup plate are fixed with a pair of Connection Block two.Left and right two top tip parts of the similar M type of back backup plate are arranged with a pair of hinge.It is inverted Y-shaped that arm frame is, that end of the bifurcated that two arm frames are inverted Y-shaped is hinged by hinge and back backup plate, on arm frame, be fixed with Connection Block one, Connection Block one and Connection Block two are comprised of cylinder, both ends of the spring is fixed between the cylinder and cylinder in Connection Block one and Connection Block two by inserting the iron prop axle of Connection Block one and Connection Block two, and iron prop axle is tightened on Connection Block one and Connection Block two by nut screw thread up and down.Spring can add radical according to user's training strength, and left and right is respectively established two conventionally, and left and right is respectively established within five the safest, at most respectively establishes five, minimumly respectively establishes one.The upper and lower both sides of the extended pipe of the two arm frame other ends are provided with a pair of spacing spring column, and extension bar is Y type, and the extended sleeve pipe in one end is provided with several spacing holes, and the sleeve end of two extension bars is inserted on the extended pipe of two arm frames, and spacing spring column snaps in spacing hole.Two extension bar front ends are fixed two handles.

The beneficial effects of the utility model are: simple in structure, reasonable in design, easy to operate, prevent that unnecessary trouble from appearring in people in body-building, its safety particularly, dynamics is adjustable, size is adjustable, meets national physical training fan's needs, and this exerciser structure is small and exquisite, cost is low, in applicable family, take exercise, good looking appearance and novelty, used by reality, result of use is very good, is the health and fitness facilities that a kind of serviceability is good.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.

Fig. 1 is the front view of the utility model example structure schematic diagram.

Fig. 2 is the side view of the utility model example structure schematic diagram..

Number in the figure:

1, handle 2, spacing spring column 3, extension bar 4, arm frame 5, iron axle 6, Connection Block one

7, spring 8, hinge 9, shoulder belt 10, back backup plate 11, Connection Block two.

The specific embodiment

As shown in Fig. 1-Fig. 2, a kind of chest muscle exerciser is comprised of handle 1, spacing spring column 2, extension bar 3, arm frame 4, iron axle 5, Connection Block 1, spring 7, hinge 8, shoulder belt 9, back backup plate 10 and Connection Block 2 11.The structure centre that back backup plate 10 is whole chest muscle exerciser, backup plate 10 profiles in back are similar to M, and centre is the corresponding vertebral location of high spot slightly.Shoulder belt 9 two ends are fixed on the top and bottom of back backup plate 10, and shoulder belt 9 is in back backup plate 10 inner sides, the corresponding shoulder position of two shoulder belts 9, two top ends of the V part in the middle of similar M type.Two lower ends of the similar M type of back backup plate 10 are fixed with a pair of Connection Block 2 11.Left and right two top tip parts of the similar M type of back backup plate 11 are arranged with a pair of hinge 8.Arm frame 4 is inverted Y-shaped, that end of the bifurcated that two arm frames 4 are inverted Y-shaped is hinged by hinge 8 and back backup plate 10, on arm frame 4, be fixed with Connection Block 1, Connection Block 1 and Connection Block 2 11 are comprised of cylinder, spring 7 two ends are fixed between the cylinder and cylinder in Connection Block 1 and Connection Block 2 11 by inserting the iron prop axle 5 of Connection Block 1 and Connection Block 2 11, and iron prop axle 5 is tightened on Connection Block 1 and Connection Block 2 11 by nut screw thread up and down.Spring 7 can add radical according to user's training strength, and left and right is respectively established two conventionally, and left and right is respectively established within five the safest, at most respectively establishes five, minimumly respectively establishes one.The two upper and lower both sides of the arm frame extended pipe of 4 other end are provided with a pair of spacing spring column 2, extension bar 3 is Y type, the extended sleeve pipe in one end is provided with several spacing holes, and the sleeve end of two extension bars 3 is inserted on the extended pipe of two arm frames 4, and spacing spring column 2 snaps in spacing hole.Two extension bar 3 front ends are fixed two handles 1.
