Description

The structure of economic simple type treadmills

Technical field

The utility model relates to a kind of treadmills, particularly relates to a kind of structure of economic simple type treadmills.

Background technology

Because people are to the continuous lifting of healthy pay attention to day by day and living standard, add the unbalanced of diet, the use that causes sports equipment is increasingly extensive, and the treadmills used of sport and body-building at present, need to use the oil pressure rod more, cause that manufacturing cost is higher, easily to give birth to fault and speed of production slow, so the necessity that adds the research and design improvement is again arranged.

In view of this, the utility model designer is engaged in the experience that exercise is made, designed, concentrated research long-pending ten several years, exhaust intelligence, at above disappearance, the method for seeking to improve, and have a fling at through experiment repeatedly, and utility model goes out the structure of this economic simple type treadmills finally.

Summary of the invention

Main purpose of the present utility model is: the structure that a kind of economic simple type treadmills is provided, but be at the mounting of a horizontal on ground, open a pivoted pole beyond respectively is connected with one group and becomes parallel left and right sides pedal bridge backward in its front end mast both sides, be installed on pedal on the pedal bridge respectively, then be connected with the fixed mount that extends back in the middle of the mast, between fixed mount tail end and mounting and be articulated with a friction pulley, still be connected with a machine leader on the friction pulley, and the machine leader both sides are to be connected with affixed drive sheet on the pivoted pole respectively with connecting rod, the mounting tail end still is pivoted with an adjusting lever in addition, the adjusting lever leading edge has brake pad, can adjust the degree of connecting airtight of friction pulley and brake pad via the turn adjusting lever, change mutual frictional force size to impel, when the user steps on pedal, the trample action that cooperates the motion of marking time, about the mutual in regular turn downward pushes pedals of the application of force, revolve and move and the pin of the application of force impels the pedal bridge to drive pivoted pole downwards, because the reach of the drive sheet on the pivoted pole, meeting traction link pulling machine leader and friction pulley revolve and move, and another not stressed pedal bridge, then, machine leader impel connecting rod to drive the reverse displacement of pivoted pole because of revolving to move, cause drawing pedal bridge upwards, make the force application movement effectiveness of marking time that reaches left and right sides oscilaltion, and can be via the turn adjusting lever, and the frictional force size of adjustment friction pulley, make to need not the oil pressure rod, to reach the economic aim that reduces manufacturing cost.

Secondary objective of the present utility model is: the structure that a kind of economic simple type treadmills is provided, its machine leader both sides are for being connected with affixed drive sheet on the pivoted pole respectively with the connecting rod that can adjust length, and can utilize the length that changes connecting rod, to adjust the height of pedal, make to reach to change the variation that bottom spoke produces the step pitch size on the pedal, to be suitable for the purpose that different personages or different training are used.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of structure of economic simple type treadmills is characterized in that: it includes mounting, pedal bridge, connecting rod, friction pulley and adjusting lever; Wherein but mounting is a horizontal firm pedestal of using on the ground, protruding out the mast both sides at its front end is connected with one group with pivoted pole respectively and becomes parallel left and right sides pedal bridge backward, be installed on a pedal on the pedal bridge respectively, then be connected with a fixed mount that extends back in the middle of the mast, be articulated with a friction pulley between fixed mount tail end and the mounting, be connected with a machine leader on the friction pulley, and the machine leader both sides are connected with affixed drive sheet on the pivoted pole respectively with connecting rod, in addition, the mounting tail end is pivoted with an adjusting lever, the adjusting lever leading edge has brake pad, and the turn adjusting lever can be adjusted the degree of connecting airtight of friction pulley and brake pad.

Adopt the advantage that the utlity model has of technique scheme to be: low cost of manufacture, the manufacturing cycle is short; Be easy to make best the adjustment at different users's health.

The specific embodiment

For your juror can further be familiar with and understand structure of the present utility model and effect thereof, cooperate graphic being described in detail as follows for embodiment now:

Please cooperate and consult Fig. 1～shown in Figure 5, the utility model is combined with adjusting lever 5 by mounting 1, pedal bridge 2, connecting rod 3, friction pulley 4; Wherein but mounting 1 is a horizontal firm pedestal of using on the ground, protruding out mast 10 both sides at its front end is connected with one group with pivoted pole 21 respectively and becomes parallel left and right sides pedal bridge 2 backward, be installed on a pedal 20 on the pedal bridge 2 respectively, then be connected with a fixed mount that extends back 11 in the middle of the mast 10,1 of fixed mount 11 tail ends and mounting also are articulated with a friction pulley 4, be connected with a machine leader 41 on the friction pulley 4, and machine leader 41 both sides are to be connected with affixed drive sheet 22 on the pivoted pole 21 respectively with connecting rod 3, mounting 1 tail end is pivoted with an adjusting lever 5 in addition, adjusting lever 5 leading edges have brake pad 50, can adjust the degree of connecting airtight of friction pulley 4 and brake pad 50 via turn adjusting lever 5, change mutual frictional force size to impel; Connecting rod 3 is provided with movable lock spiral shell 30 in case of necessity becomes the adjustable structure, makes to adjust the length that changes connecting rod 3.

When practical operation is used, the user settles the utility model on the ground with mounting 1, and according to user's step pitch size, adjust movable lock spiral shell 30, to change the length of connecting rod 3 interlockings, and reach the high and low position of adjusting pedal 20, make and produce the variation of going up bottom spoke step pitch size, with via turn adjusting lever 5, impel the degree of connecting airtight that changes friction pulley 4 and brake pad 50, to adjust the frictional force size that friction pulley 4 is born, use for different training, when the user steps on pedal 20, the mutual athletic performance of marking time of the downward pushes pedals 20 of the application of force in regular turn about cooperation, and the pin of the application of force impels pedal bridge 2 to drive pivoted poles 21 downwards to revolve and move, because the drive sheet 22 reach meeting traction link 3 pulling machine leaders 41 on the pivoted pole 21 revolve with friction pulley 4 and move, and another not stressed pedal bridge 2, then, machine leader 41 moves the connecting rod 3 drive pivoted poles 21 reverse displacements that impel the opposite end because of revolving, cause drawing pedal bridge 2 upwards, can reach the mark time motion effectiveness of the application of force of left and right sides oscilaltion in this way, because unitary construction is simple and easy, and need not the oil pressure rod, can reduce manufacturing cost and faster production.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from following claim and limited, can make many modifications, change, or equivalence, but but all will fall within the claim restricted portion of the present utility model.
