Abstract

The utility model belongs to the field of fitness equipment, and particularly relates to a double-wing push-up fitness device. The fitness device adopts gear and rack transmission design, and when gears serve as driving parts and a double-sided rack serves as a driven part, linear speed of pitch circles of the gears is equal to speed of reciprocating linear movement of the double-sided rack; meanwhile, the double-wing lever principle is adopted, and when a person does push-ups to exercise muscles of the arms and the legs, the muscle of the chest is exercised since the chest of a human body leans against a prostration support frame to perform up-down movement; by the aid of cylindrical handles arranged on a left-wing swing arm and a right-wing swing arm, muscles and bones of the wrists are exercised while up-down movement of arm swinging, and slippage of the palms and palm support frames when the person does push-ups ordinarily is prevented.

Description

A kind of biplane push-up body-building device

Technical field

the utility model belongs to body-building apparatus field, is specifically related to a kind of biplane push-up body-building device.

Background technology

push-up is common body building, mainly tempers muscle, the especially chest muscle of upper limbs, waist and belly.The muscle group that push-up is mainly taken exercise has pectoralis major and the triceps muscle of arm, also tempers other positions of anterior bundle of deltoid, costoscapularis and coracobrachilalis and health simultaneously.The existing fitness equipment for push-up is of a great variety, each has something to recommend him, but their many function of dominants are single, purposes is narrower, can only carry out push-up exercise, and exercise does not have incremental process, arm and chest muscle fatiguability are ached, and the muscle group of exercise is comparatively single.

Summary of the invention

for overcoming above-mentioned defect, the purpose of this utility model is to provide a kind of biplane push-up body-building device of tempering arm and leg muscle but also tempering chest muscle, activity wrist muscles and bones simultaneously.

the purpose of this utility model is achieved through the following technical solutions:

a kind of biplane push-up body-building device of the present utility model, comprise: base, with the vertical rack-and-pinion assembly bracket being fixedly connected with of base, vertically be arranged on the two-sided rack in wheel tooth bar assembly bracket, the left gear axle that is arranged on rack-and-pinion assembly bracket both sides and rotates freely, right gear axle, respectively fixedly sleeved left gear, right gear on left gear axle, right gear axle; Two sides, the left and right tooth bar of described the two-sided rack meshes with left gear, right gear respectively; On described left gear axle, right gear axle, be fixedly connected with respectively the left wing's swing arm, the right flank swing arm that are symmetric, the swing arm of described left wing, right flank swing arm equal intervals are fixedly installed more than one cylindrical handle;

described rack-and-pinion assembly bracket upper end offers the opening moving up and down for convenient double-sided tooth bar, and described the two-sided rack upper end is connected with hinge assembly; Described hinge assembly comprises: with the vertical lower hinge that is fixedly connected with, is U-shaped shape in the two-sided rack upper end, bearing pin, upper hinge; On described lower hinge, upper hinge, all offer the pin shaft hole through described bearing pin, described pin shaft hole, bearing pin are and are horizontally disposed with, and described bearing pin is fixing on lower hinge by upper hinge through described pin shaft hole; Described upper hinge upper end is fixedly connected with the prostrate bracing frame that is circular-arc.

further, on described prostrate bracing frame, adopt leather parcel.

further, the cylindrical handle quantity arranging in described left wing swing arm, right flank swing arm is respectively 3.

a kind of biplane push-up body-building device that the utility model provides, this fitness equipment adopts rack-and-pinion driven Design, when gear is as driving link, the two-sided rack is during as Passive part, the linear velocity of pitch circle equals the reciprocating linear translational speed of the two-sided rack, adopt biplane lever principle simultaneously, when carrying out push-up exercise arm and leg muscle, because leaning against on prostrate bracing frame, human chest moves up and down, also tempered human chest muscle simultaneously, be arranged on left wing's swing arm, cylindrical handle in the right flank swing arm wrist muscles and bones that also looses when swing arm moves up and down, and the skidding of the palm of the hand and palm bracing frame while having prevented from generally pressing your body up from the floor with your arms and then lower it slowly.

Accompanying drawing explanation

for ease of explanation, the utility model is described in detail by following preferred embodiment and accompanying drawing.

fig. 1 is a kind of biplane push-up body-building device structural representation of the utility model;

structural representation when Fig. 2 is the another kind of state of a kind of biplane push-up body-building device of the utility model;

wherein Reference numeral is: 1. base, 2. rack-and-pinion assembly bracket, 3. the two-sided rack, 4. left gear, 5. right gear, 6. left gear axle, 7. right gear axle, 8. left wing's swing arm, 9. right flank swing arm, 10. handle, 11. openings, 12. times hinges, 13. bearing pins, 14. upper hinges, 15. prostrate bracing frames.

The specific embodiment

in order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
