Leg muscle is home use exercise device by a small margin
Technical field
The present invention relates to Household fitness equipment, particularly for the springboard of leg muscle exercise.
Background technology
Family fitness equipment more and more welcomed by the people, Household fitness equipment commercially available is at present a lot, but be not applicable to the equipment that jumping is beneficial to leg muscle exercise, and body-building apparatus common on the market belongs to auxiliary type, box-like sports equipment mostly, its volume ratio that takes up room is larger, higher requirement is had to place, and expensive, can not promote the use of.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and designing, and provides a kind of leg muscle home use exercise device by a small margin, and its structure is simple, it is little to take up room, price is low.
In order to solve the problem, the present invention adopts following scheme:
Comprise the springboard be installed on base, springboard comprises the arc at middle part and is connected to the pedal at arc two ends, and pedal is provided with bandage; The upper surface transverse end offside of base is provided with the chute of closed at both ends, and rolling in chute is provided with back shaft, and longitudinal bilateral symmetry of chute is provided with baffle plate, with the guide slot of the axle head of installation back shaft on baffle plate; Built-in spring is installed between back shaft and the lower surface of arc, between back shaft and the lower surface of pedal, external spring is installed, between built-in spring and external spring, form class V-structure.
Further improvement as technique scheme:
The central shaft of described back shaft is parallel with the central shaft of arc.
The outer end of described pedal is provided with the block connecting bandage, and enterprise's inner end is with the snapping block interlocked with bandage, and the end of bandage is with the discount interlocked with snapping block.
Technique effect of the present invention is:
Structure of the present invention is very simple, uses easy to operate, to human leg even whole body perform physical exercise, its train on is good, cheap, is suitable for promoting the use of; And because motion amplitude is less, the present invention is also particularly suitable for the elderly and uses.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, comprise the springboard 1 be installed on base 9, springboard 1 comprises the arc 11 at middle part and is connected to the pedal 12 at arc 11 two ends, pedal 12 is provided with bandage 2; The upper surface transverse end offside of base 9 is provided with the chute 13 of closed at both ends, and rolling in chute 13 is provided with back shaft 3, and longitudinal bilateral symmetry of chute 13 is provided with baffle plate 10, with the guide slot 14 of the axle head of installation back shaft 3 on baffle plate 10; Built-in spring 4 is installed between the lower surface of back shaft 3 and arc 11, external spring 5 is installed between the lower surface of back shaft 3 and pedal 12, between built-in spring 4 and external spring 5, form class V-structure.
When the present invention uses, human body bipod is placed on pedal 12 respectively, fastens bandage 2; Springboard 1 is firmly trampled by foot, and decline to base 9 at springboard 1 and clash into, in knockout process, pedal 12 declines gradually, and back shaft 3 under the action of the spring, to the middle part rolling slip of arc 11; Under the elastic reaction of built-in spring 4 and external spring 5, springboard 1 restores to the original state, and promotes that human foot upsprings; So repeatedly, the muscle of human leg is performed physical exercise.
Further, for ensureing the spring stability of springboard 1, the central shaft of back shaft 3 is parallel with the central shaft of arc 11.
Further, the outer end of pedal 12 is provided with the block 6 connecting bandage 2, and enterprise's inner end is with the snapping block 7 interlocked with bandage 2, and the end of bandage 2 is with the discount 8 interlocked with snapping block 7.
Above illustrated embodiment is better embodiment of the present invention, only be used for conveniently the present invention being described, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristic, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristic content of the present invention, all still belong in the scope of the technology of the present invention feature.
