Description

A kind of device for moderating force's instrument resistance
Technical field
The present invention relates to a kind of in the fitness equipment for carrying out strength building, the device for resistance to be adjusted.
Background technology
The resistance device of existing body-building strength equipment realizes that clump weight is by multiple units by drawing clump weight Counterweight iron block is superimposed up and down, and the size for adjusting tractive resistance is by changing clump weight weight, increasing or decreasing different number Unit counterweight iron block realizes the change of clump weight weight, and the unit iron block once drawn is more, resistance is bigger, otherwise resistance Power is with regard to smaller.Using process, it is to change the quantity for drawing unit counterweight iron block by manual bolt to adjust drag size, one Unit counterweight iron block weight is usually 2.5kg or 5kg, that is to say, that it is unit counterweight iron block weight to adjust tractive resistance every time Multiple cannot adjust arbitrary Resistance Value, and manual bolt adjusting is inconvenient to use, is easy to cause mechanical breakdown.
Invention content
In view of this, the present invention provides a kind of device for moderating force's instrument resistance, pass through adjustable track platform Angle with horizontal plane is to the almost linear adjusting instrument drag size of essence.
In order to solve the above technical problems, the technical scheme is that using a kind of dress for moderating force's instrument resistance It sets, including chassis, further includes the orbital platform being mounted on chassis;Described orbital platform one end is connect by axis pin with chassis, Orbital platform is spun upside down along axis pin, the other end is hung on by drawstring on chassis;The orbital platform upper edge rail Track is arranged in road platform extending direction;Further include the leading screw with parallel track, the leading screw can be along its axle center rotation;The leading screw On be cased with the nut coordinated with leading screw;It is fixed with trolley on the nut, the rail wheel coordinated with track is provided on trolley;Institute It states and is provided with clump weight on trolley;It further include the driving device for driving leading screw to rotate.The utilization lever principle of the present invention is led to Over-driving device drives lead screw rotation, to adjust the position of clump weight.According to lever principle, torque is with active force at anti- Than.Therefore it adjusts clump weight and can be used for linear adjusting resistance at a distance from fulcrum (link position of orbital platform and chassis) Power.
As an improvement being provided with pulling force sensor on the drawstring;Further include a controller, the controller with Pulling force sensor and driving device connection.Pulling force sensor is used to feed back the size of value of thrust, and controller passes through driving device Leading screw is driven to rotate, the position for automatically adjusting clump weight.
As a kind of further improvement, it is provided with column on the trolley, the clump weight is through on column.Column is used In fixed weight block, the quantity by increasing and decreasing clump weight can also adjust drag size.
As a kind of further improvement, the column is two.Better fixed weight block, preventer are revolved along column Turn.
As another further improvement, it is provided with leading screw bearing on the orbital platform, the leading screw passes through axis It holds and is connect with leading screw bearing.
As an improvement being provided with fixed pulley at the top and bottom of the chassis, the drawstring bypasses at the top of chassis successively With the fixed pulley of bottom.
As an improvement being provided with annular groove on the rail wheel outer ring surface, the track is connected in annular groove. Prevent nut from rotating by groove and track clamping so that nut is not rotation with the rotation of leading screw, can only be rotated with it and preceding After move.
As an improvement the driving device is motor, certain driving device may be to appoint including artificial mechanism etc. Meaning mode drives the equipment that leading screw rotates.
The invention has the beneficial effects that:The device for moderating force's instrument resistance with above structure, structure It is simple to operation, change traditional manual operating force measuring device tool resistance device, it is big come the resistance of moderating force's instrument by controller It is small, multi-gear adjustment resistance, electrodeless adjustment resistance may be implemented.It in addition can be by controller programming, realizing the resistance of strength instrument The automation control of power.

Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, With reference to embodiment The present invention is described in further detail.
As shown in Figure 1, the present invention includes chassis 1, further include the orbital platform 14 being mounted on chassis 1;The track is flat 14 one end of platform is connect by axis pin with chassis 1 so that orbital platform 14 can be spun upside down along axis pin, and the other end passes through drawstring 6 It hangs on chassis 1;1 top and bottom of chassis are provided with fixed pulley 12, and the drawstring 6 bypasses 1 top and bottom of chassis successively Fixed pulley 12.Track 3 is arranged in 14 upper edge orbital platform of the orbital platform, 14 extending direction;Further include parallel with track 3 Leading screw 10, the leading screw 10 can be along its axle center rotations;The nut coordinated with leading screw 10 is cased on the leading screw 10;On the nut It is fixed with trolley 4, the rail wheel 13 coordinated with track 3 is provided on trolley 4;It is provided with annular groove on 13 outer ring surface of rail wheel, The track 3 is connected in annular groove.Leading screw bearing 2 is provided on orbital platform 14, the leading screw 10 passes through bearing and silk Thick stick bearing 2 connects.Clump weight 5 is provided on the trolley 4;Column 11 is provided on trolley 4, the clump weight 5 is through at column On 11.The column 11 is two.It further include the driving device 9 for driving leading screw 10 to rotate.Driving device 9 is motor, when Right driving device 9 may be the equipment for including the driving leading screw rotation of any ways such as artificial mechanism.6 are provided with pulling force on drawstring Sensor 7;Further include a controller 8, the controller 8 is connect with pulling force sensor 7 and driving device 9.
