具体实施方式
为达成上述目的及功效，本发明所采用的技术手段及构造，兹绘图就本发明较佳实施例详加说明其特征与功能如下，以利完全了解。
请参阅图1至图5所示，本发明揭示了一种阻力装置，包括：阻力源、绞盘2、拉绳3、滑轮组4、理线机构、拉线6及固定板7；所述阻力源的输出端与绞盘2一端连接，所述绞盘2另一端枢设于固定板7，所述固定板7与阻力源之间设有所述理线机构，所述拉绳3的一端固设于绞盘2上，所述拉绳3的另一端凸伸出理线机构，所述绞盘2另一端的端部凸设有绕线柱21，所述滑轮组4包括至少一定滑轮41及至少一动滑轮42，所述定滑轮41固设于固定板7上，所述动滑轮42固设于理线机构上，所述拉线6的一端固设于绕线柱21上，所述拉线6缠绕于绕线柱21、定滑轮41与动滑轮42之间，所述拉绳3与理线机构连动，当所述阻力源带动绞盘2转动时，所述绕线柱21转动使拉线6缠绕或松开，所述拉线6带动理线机构，所述理线机构带动拉绳3有序在绞盘2上卷绕，其中，于实施例中，所述拉线6的另一端可以固设于固定板7上，但并不以此为限，所述拉线6的另一端也可以固设于理线机构上，还可以回绕至绕线柱21,或者其它可以固定的地方。
因此，本发明通过滑轮组4替代螺纹结构，且本发明通过滑轮组4、理线机构及拉线6的配合作用，起到导绳的作用，并减小了导绳过程中的阻力，即当拉绳3缠绕于绞盘2的过程中，带动绕线柱21，使拉线6松开缠绕绕线柱21，所述理线机构运动，使得动滑轮42与定滑轮41之间的拉线6长度逐渐延长，且所述拉绳3与理线机构连 动，让理线机构带动拉绳3在绞盘2上有序卷绕，因此本发明可减少制造成本、降低制造精度要求及保证拉绳3有序卷绕，且整体结构简单。
其中，所述阻力源可以为电机1、电磁刹车装置、磁粉刹车装置、风阻发生装置、或水阻发生装置任意一种，本发明的实施例以阻力源为电机1进行说明，所述电磁刹车装置、磁粉刹车装置、风阻发生装置及水阻发生装置为本领域的公知内容，在此不赘述，所述理线机构为导轨8与滑块5配合的移动机构或者杆件的摆动机构。
再者，本发明还可以包括一卷簧组件9，所述卷簧组件9包括一卷簧外壳(图中未示出)及一卷簧(图中未示出)，所述卷簧外壳固设于固定板7上，所述卷簧的一端固设于卷簧外壳，所述卷簧的另一端固设于绞盘2另一端上，使得当施力让拉绳3解开对绞盘2的缠绕过程中，会使得缠绕于绞盘2另一端上的卷簧收紧，而当不施力时，在卷簧的弹性恢复力作用下，卷簧会解开缠绕，使得拉绳3自动再次缠绕于绞盘2上，实现自动恢复。
其次，本发明还包括一固设于电机1与固定板7之间的外壳10及两间隔设于绞盘2下方两侧的底支撑件06，所述外壳10包覆绞盘2，所述拉绳3的另一端凸伸出外壳10，所述外壳10设有供拉绳3活动的绳槽101，所述底支撑件06连接固定于固定板7与电机1之间。
接着，所述电机1的输出端可以通过套设一垫片04及一轴承05与绞盘2一端连接，即所述电机1的输出端、垫片04及轴承05设于 绞盘2一端内，使得电机1的输出端转动使绞盘2的转动受到阻碍。
另外，本发明还可以包括弹簧02，所述弹簧02的一端与理线机构连动，所述弹簧的另一端与电机1固定，从而便于利用弹簧02使理线机构往复运动。

进一步，所述弹簧02的一端与滑块5连动，所述弹簧02的另一端与电机1固定，从而当拉绳3缠绕于绞盘2的过程中，带动绕线柱21，使拉线6松开缠绕绕线柱21，所述滑块5在弹簧02的弹力作用下朝弹簧02的另一端移动，使得动滑轮42与定滑轮41之间的拉线6长度逐渐延长，且所述拉绳3的另一端与滑块5连动，让滑块5带动拉绳3在绞盘2上有序卷绕。
进一步，所述滑块5的上方固设有一基座01，所述基座01设有 一供拉绳3的另一端凸伸出的通孔011，所述通孔011的一侧设有一具有凹槽0121的次定滑轮012，所述拉绳3卡入次定滑轮012的凹槽0121内，所述通孔011的另一侧设置所述动滑轮42，从而便于对拉绳3施力，减少拉绳3的阻力，使得所述拉绳3的另一端与滑块5连动。
所述弹簧02的一端固设于基座01上，所述电机1上固设有支撑架03，所述弹簧02的另一端固设于支撑架03上，使得当施力让拉绳3解开对绞盘2的缠绕过程中，滑块5带动基座01朝固定板7方向移动，拉伸弹簧02，而当不施力时，所述滑块5在弹簧02的弹力作用下朝弹簧02的另一端移动，使得动滑轮42与定滑轮41之间的拉线6长度逐渐延长，且所述拉绳3的另一端与滑块5连动，让滑块5带动拉绳3自动再次缠绕于绞盘2上，实现自动恢复。
请参阅图4所示，本发明的实施例二中所述理线机构采用杆件的摆动机构，所述杆件的摆动机构包括滑轮轴071及至少一连杆072，所述滑轮轴071穿设动滑轮42，所述滑轮轴071的端部与连杆072固定，所述连杆072的底端可转动地连接于一套设于底支撑件06上的连接块073，从而利用连杆072的摆动，带动滑轮轴071及动滑轮42，让拉绳3可以在绞盘2上有序卷绕，所述连杆072的摆动量等于拉绳3在绞盘2上的移动量。
进一步，本发明还可以包括弹簧拉板074及一具有凹槽0121的次定滑轮012，所述拉绳3卡入次定滑轮012的凹槽0121内，所述滑轮轴071穿设次定滑轮012及弹簧拉板074，所述弹簧拉板074可 以为U型，所述电机1上固设有支撑架03，所述弹簧02的一端固设于弹簧拉板074，所述弹簧02的另一端固设于支撑架03上，所述弹簧拉板074夹设次定滑轮012及动滑轮42，从而使得弹簧02能带动滑轮轴071往复运动，使得动滑轮42与定滑轮41之间的拉线6长度逐渐改变。
请参阅图5所示，本发明的实施例三中所述理线机构采用杆件的摆动机构，所述杆件的摆动机构包括滑轮轴071、三角块075及至少一连杆072，于本实施例中，所述连杆072及三角块075的数量均为二，但并不以此为限，所述滑轮轴071穿设动滑轮42，所述滑轮轴071的端部与三角块075的其中一角固定，所述固定板7与电机1之间固设有导轨8，所述连杆072的顶端可转动地连接于导轨8，所述连杆072的底端与三角块075的另一角连接，所述三角块075的最后一角连接一连接条076，所述连接条076可转动地连接于固定板7上，从而利用连杆072及三角块072的配合摆动，带动滑轮轴071及动滑轮42，让拉绳3可以在绞盘2上有序卷绕，所述三角块075的其中一角的摆动量等于拉绳3在绞盘2上的移动量。
进一步，本发明还可以包括弹簧拉板074及一具有凹槽0121的次定滑轮012，所述拉绳3卡入次定滑轮012的凹槽0121内，所述滑轮轴071穿设次定滑轮012及弹簧拉板074，所述弹簧拉板074可以为U型，所述电机1上固设有支撑架03，所述弹簧02的一端固设于弹簧拉板074，所述弹簧02的另一端固设于支撑架03上，所述弹簧拉板074夹设次定滑轮012及动滑轮42，从而使得弹簧02能带动 滑轮轴071往复运动，使得动滑轮42与定滑轮41之间的拉线6长度逐渐改变。
