Description
Technical field
The present invention relates to a kind of body building training device, especially a kind of body building training device.
Background technology
In modern society, along with the extension of working time, the quickening of rhythm of life, the increase of operating pressure, people
Health worse and worse, sub-health population is more and more, thus office body-building apparatus, body building of wushu equipment, Tai Ji body-building
The market of equipment expands rapidly, and existing body-building apparatus product is excessively delayed, it is impossible to meet and adapt to the potential of society
Demand.
With the lifting of scientific consciousness, the more scientific training of body-building, sentific training is mainly reflected in the section of training method
In the science of and training device.At present on the market, the training equipment for upper limbs is simultaneously few, and belongs to pure work mostly
Dynamic equipment, can not be according to training strength adjustment be realized the need for trainer, most common is exactly in park or cell, for old
The rotating disk of human hand training.And upper limb trainer material of the other with strength condition, there is following defect：1st, due to equipment knot
Structure is complicated, accessory is more, causes overall heaviness；Because of the friction between accessory when the 2nd, using, noise is big；3rd, movable part is easy to wear,
It is prone to accidents, causes user injured；4th, high to site requirements, equipment cost is high.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of simple structure, train easy to operate, noise is small
Body building training device.
The technical solution adopted for the present invention to solve the technical problems is：A kind of body building training device, including frame, also wrap
Include,
Rotation is installed on the bent axle at frame, and the bent axle includes trunnion, connecting rod neck and for connecting trunnion and company
The crank of bar neck；
Rocking handle, is fixed on the both ends of bent axle axial direction；
It is fixed at frame and for the damping unit to bent axle offer rotary resistance, the damping unit is piston-type hydro
Cylinder pressure, the axial direction of the piston-type hydraulic cylinder is axially perpendicular with bent axle, and cylinder body is hinged cooperation with frame, the piston outside cylinder body
Boom end is hinged cooperation with connecting rod neck.
The beneficial effects of the invention are as follows：Bent axle includes trunnion, crank and connecting rod neck, and connecting rod neck passes through crank and trunnion
Connection.The rotation of bent axle is realized by rocking handle, so that band dynamic crankshaft upper connecting rod neck is also rotated together, due to piston rod end and company
Bar neck is hinged, therefore bent axle acts on and is herein, and moment of torsion is converted into the reciprocating motion of piston rod in piston-type hydraulic cylinder.Due to work
, it is necessary to power is input into when stopper rod overcomes hydraulic oil to do work, it is therefore desirable to by different physical training styles, realize that hand or leg are had an effect
To realize the rotation of crank, the purpose of body-building is thus reached.In this patent, integrally only need to five basic elements of character can just reach it is strong
Body purpose, therefore simple structure, and train easy to operate, by increasing crank rotation resistance, reach the intensity control to taking exercise
System；The friction that damping unit is changed in traditional approach increases the mode of resistance, using hydraulic cylinder mode, reduces rubbing between part
Noise when wiping, therefore greatly reducing running, and equipment life consumption；Rocking handle can realize Double-directional rotary, you can with reality
Now bidirectional-movement clockwise and anticlockwise, directive will not limit.

Adjust.As shown in figure 5, transverse axis is the rotational angle theta reference axis of bent axle 2, the longitudinal axis is the reference axis of damping force F.The corner of bent axle 2 will reflect indirectly
On the stroke of piston rod 321, and size required drag size for overcoming when i.e. piston rod 321 stretches is damped, namely overcome this
The strength applied needed for body builder during resistance.Wherein, when piston rod 321 is moved in piston-type hydraulic cylinder 3, piston rod 321 is deposited
Stretch out it is most short, stretch out the two extreme positions most long, and be located at the centre position between two limit positionses for crossover position；
According to the characteristic of piston-type hydraulic cylinder 3, the change in location of piston rod 321 is realized by turning crankshaft 2, in two limit positionses
It is required to overcome damping force minimum (because the corresponding piston rod stroke change of crank rotation angle is minimum), and in crossover position when institute
Damping force need to be overcome maximum (the now corresponding stroke change relative maximum of crank rotation angle).The a certain crank of bent axle 2 is vertically lived
When hypothesis corner is 0 ° during plug connecting rod, curve s1 is the damping curve schematic diagram that piston rod 321 is located at transitional intermediate positions；Curve
S2 is the state that another piston rod 321 is located at two ends extreme position.In the present embodiment, using the phase interworking of two-piston formula hydraulic cylinder 3
Close, and angle in 90 ° between two connecting rod necks 23, then with the rotation of bent axle 2, piston rod 321 is required to be overcome two-piston formula hydraulic cylinder 3
Resistance be respectively curve s1 and curve s2, then two-piston formula hydraulic cylinder 3 cooperate after it is required overcomes resistance sum, as
Curve s1 and curve s2 the numerical value sum on y direction, it is as seen from the figure, no matter bent when two connecting rod necks, 23 angles are 90 °
Which kind of state axle 2 is now in, and the required damping force sum for overcoming will be relatively steady, therefore it is ensured that body builder's body-building
When, it is also smaller relative fluctuation for the moment of torsion that rocking handle 212 is applied, can so ensure the harmony of force, improve strong
The experience sense of body person, and can allow body-building more science, the need for meeting physiologically.
Wherein, the purpose of flywheel 4 is the rotary inertia for increasing damping structure at trunnion 21, can balance damping output
Fluctuation, improves the pulse feature of damping output, so as to further increase body builder's experience sense.
Input block and output unit are provided with frame 1, the input block includes rotating the number of turns for monitoring bent axle 2
