Description

一种滑轮高度调节机构 技术领域
本发明涉及门窗领域，尤其涉及一种滑轮高度调节机构。
背景技术
针对吊趟门上的吊滑轮机构的高度调节，发明人对此现有技术进行改良，于2021年12月10日公开了一篇公告号为“CN215108237U”的中国实用新型专利，该专利公开了一种可调节升降的吊滑轮机构，保证了齿轮螺母与调节件的稳定啮合，从而实现吊趟门的顺畅升降。
但这种利用螺栓进行调节吊滑轮机构升降的传统方式，仍然存在以下的缺陷，亟需进行改良解决：
(1)调节件呈倾斜设置，且通过齿轮的啮合传动。本机械领域内的专业人员可知，调节吊滑轮机构升降时，需使用螺丝刀插接在调节件上进行拧转，进而带动螺栓转动，而倾斜设置的调节件不便于受力，进而并不便于调节操作，同时，当齿轮啮合过程中出现卡顿时，会不便于拧转调节。
(2)由于吊滑轮机构的升降受力均集中作用在螺栓上，这使得螺栓不得不选用直径较大的型号，进而使得挂架的宽度较大，进而使得门窗框体的导槽宽度增大，进而使得门窗整体安装中的缝隙都较大，而随着现代社会的装修审美观念提高，这将影响到门窗的美观问题。
发明内容
为了克服上述现有技术所述的至少一种缺陷，本发明提供一种滑轮高度调节机构，改变了传统一贯采用螺栓进行升降调节的方式，不仅提高升降调节的便捷性，而且改善升降调节过程中的受力，同步的，也使得门窗装配后更加的美观。
本发明为解决其问题所采用的技术方案是：
一种滑轮高度调节机构，包括滑轮组件、调节部件以及滑动调节件；所述滑轮组件连接所述调节部件，所述滑动调节件位于所述滑轮组件的一侧，其中，所述滑动调节件包括第一调节部及第二调节部，所述第一调节部与所述第二调节部的相对距离可调，即所述第一调节部与所述第二调节部相向或相背滑动设置；所述第一调节部与所述第二调节部均与所述调节部件相铰接，滑动所述第一调节部或/与所述第二调节部，使所述调节部件张合，调整所述滑轮组件与所述滑动调节件的距离。此处，滑轮组件包括滚动轮及滑动座，滚动轮转动连接在滑动座上，因此，滑轮高度调节机构中的滑轮组件与滑动调节件的距离通过滑动调节件中的第一调节部与第二调节部的滑动，从而牵引调节部件实现进行调节的目的，进而实现了调节高度位置的目的，另外，张开拉动的作用力或合拢推压的分开作用在与第一调节部与第二调节部的调节部件上，不仅实现代替传统一贯采用螺栓进行升降调节的方式，则使得连接在吊滑轮结构中的螺栓直径减小或取消吊滑轮结构中的螺栓，有利于提高吊趟门整体的美观性，而且改善升降过程中受力集中的问题，使得结构更加的牢固稳定，提高吊趟门升降调节的稳定性。
进一步地，所述滑动调节件还包括驱动杆；所述驱动杆上设置有第一外螺纹段，所述驱动杆与所述第一调节部螺纹连接，此处，发明人提供一种优选的方案在于第二调节部上设置通孔，驱动杆贯穿且转动链接第二调节部后，驱动杆与第一调节部螺纹连接，因此，通过驱动杆保证第一调节部与第二调节部可滑动在同一轴心线上，第一调节部装配限位在吊趟门的导槽内，则驱动杆转动时，则第一调节部将驱动杆的转动转换成为第一调节部的直线运动，第二调节部装配固定在吊趟门的导槽内，则第一调节部进行直线运动时，实现了第二调节部与第一调节部相向或相背滑动的效果。
进一步地，所述驱动杆的端部设置有驱动部，驱动部内置有与六角扳 手相适配的六角槽或者螺丝刀相适配的十字槽、一字槽，操作者通过内六角扳手或螺丝刀插设到驱动部进行拧转，进而实现驱动驱动杆转动的目的。
进一步地，所述驱动杆另一端转动连接所述第二调节部。
进一步地，所述驱动杆上还设置有第二外螺纹段，所述第二调节部及所述第一调节部均对应螺接在所述驱动杆上。可选的，第一调节部及第二调节部分别各自螺纹一驱动杆，即设置有第一外螺纹段的驱动杆与第一调节部螺纹连接，设置有第二外螺纹段的驱动杆与第二调节部螺纹连接，两驱动杆分开设置，则对两驱动杆施加以旋转的驱动力时，即可实现提高调节吊趟门高度效率的目的，除此外，当微调吊趟门的高度时，只需任意对其中一驱动杆转动以使第一调节部滑动或第二调节部滑动即可实现，更加便捷于吊趟门高度升降调节的操作。
除上述分置两驱动杆的方案外，所述第二外螺纹段与所述第一外螺纹段的螺旋方向相反，第二外螺纹段与第一外螺纹段位于同一驱动杆的两端，第一调节部螺纹连接在驱动杆的第一外螺纹段上，第二调节部螺纹连接在驱动杆的第二外螺纹段上，则转动驱动杆时，第一调节部与第二调节部将驱动杆的转动转换成沿着驱动杆的轴心线为方向的直线运动。由于第二外螺纹段与第一外螺纹段的螺旋方向相反，则驱动杆转动时，第一调节部与第二调节部将进行相向运动或向背运动，转动驱动杆一圈时，第一调节部与第二调节部之间的移动变量为第二外螺纹段螺距与第一外螺纹段螺距之和，因此，滑轮组件与滑动调节件之间所移动的距离也随着增大，有助于提高调节吊趟门高度的效率。
进一步地，所述驱动杆为气缸或液压缸或电磁缸的活塞杆，所述驱动杆贯穿所述第二调节部，并与所述第一调节部固定连接。因此，活塞杆贯穿第二调节部上设置的通孔后，并与第一调节部固定连接，则通过气缸或液压缸或电磁缸驱动，使得活塞杆进行直线往复运动，进而使得改变第一调节部与第二调节部之间的距离，相较于实施例及实施例螺纹调节的方式， 实现自动调节第一调节部与第二调节部之间距离的目的。
进一步地，所述调节部件包括第一活动件及第二活动件，所述第一活动件与所述第二活动件呈八字形分开设置，并且所述第一活动件的一端铰接所述滑轮组件，另一端铰接所述第一调节部，所述第二活动件的一端铰接所述滑轮组件，另一端铰接所述第二调节部。
进一步地，所述第一活动件与所述第二活动件交错设置，且所述第一活动件的一端铰接所述滑轮组件，另一端铰接所述第二调节部，所述第二活动件的一端铰接所述滑轮组件，另一端铰接所述第一调节部。
进一步地，所述调节部件还包括固定件，所述第一活动件的一端与所述第二活动件的一端均铰接所述固定件的一端上，所述第一活动件的另一端铰接所述第一调节部，所述第二活动件的另一端铰接所述第二调节部，所述固定件的另一端固定连接在所述滑轮组件上。
综上所述，本发明提供的滑轮高度调节机构，具有如下技术效果：
1)通过调节部件、第一调节部以及第二调节部的配合使用，在第一调节部以及第二调节部相向及相背滑动的作用下，进而实现调节滑轮组件与滑动调节件的距离，随着距离的变化实现调整了吊趟门的高度的目的，因此取代了传统一贯采用螺栓进行升降调节的方式，随着避免了由于螺栓需集中受力所导致直径大，使整个吊趟门装配间隙大而不美观的问题，同时，通过第一调节部与第二调节部的分开受力，也巧妙的解决了由螺栓集中受力的问题，改善升降调节过程中的受力，因此，有助于提高升降调节的便捷性。
2)本方案提供了一种驱动杆的方案，以保证并驱使第一调节部及第二调节部的相向滑动或向背活动，进而达到调整滑轮组件与滑动调节件之间的距离，因而驱动杆呈平行于滑轮组件的运动方向设置，即平行于吊趟门的水平设置，进而避免了传统在倾斜方向上操作受力不便的问题，从另一方面也提高了滑轮高度调节机构在升降调节上的便捷性。

具体实施方式
为了更好地理解和实施，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本发明。
实施例1
图1示出了第一结构示意图，图2示出了第二结构示意图，图3示出了 第一半剖示意图，图4示出了第二半剖示意图，其中，图1及图4均为本发明滑轮高度调节机构处于最低位置时的示意，图2及图3均为本发明滑轮高度调节机构处于最高位置时的示意，具体请结合图1至图4所示，本发明公开了一种滑轮高度调节机构，包括滑轮组件1、调节部件2以及滑动调节件3；滑轮组件1连接调节部件2，滑动调节件3位于滑轮组件1的一侧，其中，滑动调节件3包括第一调节部31及第二调节部32，第一调节部31与第二调节部32的相对距离可调，即第一调节部31与第二调节部32相向或相背滑动设置；第一调节部31与第二调节部32均与调节部件2相铰接，滑动第一调节部31或/与第二调节部32，使调节部件2张合，调整滑轮组件1与滑动调节件3的距离。
在本实施例中，滑动调节件3优选位于滑轮组件1的正上方，以保证在滑轮组件1连接作用在滑动调节件3的中间位置，达到最佳的受力效果，且改变滑轮组件1与滑动调节件3之间的距离时，将实现升降调节的目的。同时，滑轮组件1的滑动方向优选滑动调节件3的滑动调节方向平行，也即第一调节部31与第二调节部32相向或相背滑动的方向与滑轮组件1的滑动方向平行，因此，位于滑轮组件1的一侧的第一调节部31与第二调节部32滑动运动时，由于铰接在滑轮组件1与第一调节部31及第二调节部32之间的调节部件2具备一定的刚性，即调节部件2的长度固定不变，则使得滑轮组件1与滑动调节件3的距离随着第一调节部31与/或第二调节部32的滑动调整改变，也即第一调节部31与第二调节部32作向背运动时，将使得调节部件2产生张开拉动的作用力，使得滑轮组件1与滑动调节件3的距离缩小，实现滑轮高度调节机构的上升调节的效果，当第一调节部31与第二调节部32作相向运动时，将使得调节部件2产生合拢推压的作用力，使得滑轮组件1与滑动调节件3的距离增大，实现滑轮高度调节机构的下降的效果。
综合上述可知，滑轮高度调节机构中的滑轮组件1与滑动调节件3的 距离通过滑动调节件3中的第一调节部31与第二调节部32的滑动，从而牵引调节部件2实现进行调节的目的，进而实现了调节高度位置的目的，另外，张开拉动的作用力或合拢推压的分开作用在与第一调节部31与第二调节部32的调节部件2上，不仅实现代替传统一贯采用螺栓进行升降调节的方式，则使得连接在吊滑轮结构中的螺栓直径减小或取消吊滑轮结构中的螺栓，有利于提高吊趟门整体的美观性，而且改善升降过程中受力集中的问题，使得结构更加的牢固稳定，提高吊趟门升降调节的稳定性。
进一步的，为实现第一调节部31与第二调节部32之间的相对滑动，具体请参阅图1至图4，滑动调节件3还包括驱动杆33；其中，驱动杆33上设置有第一外螺纹段34，第一调节部31上设有与第一外螺纹段34相适配的第一螺纹孔，驱动杆33与第一调节部31螺纹连接。
对于驱动杆33与第二调节部32的连接关系，发明人提供两种情况，具体请结合图1至图4所示，驱动杆33另一端转动连接第二调节部32，或者驱动杆33另一端驱动杆33不与第二调节部32连接，具体如下：
作为最优选的方案，如图3及图4所示，第二调节部32上设置有与驱动杆33的直径相适配的通孔，当然，第二调节部32的通孔的直径在公差的范围内略大于驱动杆33的直径，驱动杆33贯穿且转动连接第二调节部32后，驱动杆33与第一调节部31螺纹连接，则装配时，驱动杆33设有第一外螺纹段34的一端穿过第二调节部32的通孔后，与第一调节部31的第一螺纹孔螺纹连接，通过驱动杆33保证第一调节部31与第二调节部32可滑动在同一轴心线上，第一调节部31装配限位在吊趟门的导槽内，则驱动杆33转动时，则第一调节部31将驱动杆33的转动转换成为第一调节部31的直线运动，第二调节部32装配固定在吊趟门的导槽内，第一调节部31进行直线运动时，实现了第二调节部32与第一调节部31相向或相背滑动的效果。
除优选的方式外，发明人还提供一种可选的方案在于，驱动杆33位于 第一调节部31的一侧，且驱动杆33的第一外螺纹段34于第一调节部31螺纹连接，第二调节部32装配固定在吊趟门的导槽内，也可实现第一调节部31与第二调节部32的相对距离可调的效果。
为实现驱动杆33的转动，具体请参阅图3，驱动杆33的端部设置有驱动部36，其中，驱动部36内置有与内六角扳手相适配的六角槽或者为螺丝刀相适配的十字槽、一字槽，操作者通过内六角扳手或螺丝刀插设到驱动部36进行拧转，进而实现驱动驱动杆33转动的目的，而第一调节部31与第二调节部32相向或相背滑动的方向与滑轮组件1的滑动方向平行，即驱动杆33呈水平设置，则操作者在操作六角扳手或螺丝刀进行拧转时更容易受力。
进一步的，具体请参阅图1至图4，调节部件2包括第一活动件21及第二活动件22，第一活动件21与第二活动件22呈八字形分开设置，并且第一活动件21的一端铰接滑轮组件1，另一端铰接第一调节部31，第二活动件22的一端铰接滑轮组件1，另一端铰接第二调节部32。其中，滑轮组件1还包括滚动轮11及滑动座12，滚动轮11转动连接在滑动座12上。具体的，为保证第一活动件21及第二活动件22更稳定铰接在滑动座12上，在本实施例中，调节部件2还包括铰接件24，铰接件24固定安装在滑动座12上，第一活动件21的一端及第二活动件22的一端分别铰接在铰接件24的两端上，第一活动件21的另一端对应铰接第一调节部31，第二活动件22的另一端对应铰接第二调节部32，则第一活动件21与第二活动件22呈八字形分开设置的目的，且通过第一活动件21实现将第一调节部31与滑轮组件1活动连接，通过第二活动件22实现将第二调节部32与滑轮组件1活动连接的目的。
实施例2
上述实施例1中提供的滑轮高度调节机构，通过驱动杆33转动以实现 调节滑轮组件1与滑动调节件3的距离，其中，转动驱动杆33一圈，第一调节部31所移动的距离为第一外螺纹段34的螺距距离，这使得滑轮组件1与滑动调节件3之间所移动的距离也较小，实现滑轮组件1与滑动调节件3之间距离的高精度调节，而当吊趟门在进行装配，高度上存在的装配误差较大时，这种微调的方式使得吊趟门的高度调节效率较低，且频繁的转动也使得操作人员的手容易产生酸痛的问题。
兹就上述提出的问题，发明人提供了一种方案在于，具体请参阅图5，基于实施例1中所提供的驱动杆33，驱动杆33上还设置有第二外螺纹段35，第二调节部32上设有与第二外螺纹段35相适配的第二螺纹孔，第二调节部32及第一调节部31均对应螺接在驱动杆33上，其他设置方案与实施例1相同。具体的，第二调节部32上设置的孔为第二螺纹孔，即第二调节部32上设置的通孔的内侧壁设置有与第二外螺纹段35相适配的内螺纹。
可选的，第一调节部31及第二调节部32分别各自螺纹一驱动杆33，即设置有第一外螺纹段34的驱动杆33与第一调节部31螺纹连接，设置有第二外螺纹段35的驱动杆33与第二调节部32螺纹连接，两驱动杆32分开设置，则对两驱动杆32施加以旋转的驱动力时，即可实现提高调节吊趟门高度效率的目的，除此外，当微调吊趟门的高度时，只需任意对其中一驱动杆33转动以使第一调节部31滑动或第二调节部32滑动即可实现，更加便捷于吊趟门高度升降调节的操作。
更进一步的，发明人提供一种最优选的方案在于，具体结合图5所示，第二外螺纹段35与第一外螺纹段34的螺旋方向相反，此时，第二外螺纹段35与第一外螺纹段34位于同一驱动杆33的两端，装配时，第二调节部32螺纹连接在驱动杆33的第二外螺纹段35上，第一调节部31螺纹连接在驱动杆33的第一外螺纹段34上，则转动驱动杆33时，第一调节部31与第二调节部32将驱动杆33的转动转换成沿着驱动杆33的轴心线为方向的直线运动。由于第二外螺纹段35与第一外螺纹段34的螺旋方向相反，则 驱动杆33转动时，第一调节部31与第二调节部32将进行相向运动或向背运动，此时，转动驱动杆33一圈时，第一调节部31与第二调节部32之间的移动变量为第二外螺纹段35螺距与第一外螺纹段34螺距之和，因此，滑轮组件1与滑动调节件3之间所移动的距离也随着增大，有助于提高调节吊趟门高度的效率。
实施例3
区别于实施例1及实施例2的地方仅在于，驱动杆33为气缸或液压缸或电磁缸的活塞杆，驱动杆33贯穿第二调节部32，并与第一调节部31固定连接。根据本机械领域内的技术手段，活塞杆通过螺栓连接与第一调节部31固定安装，其他可将第一调节部31固定安装到活塞杆上的方式均可作为螺栓连接方式的替换方式。此时，活塞杆贯穿第二调节部32上设置的通孔后，并与第一调节部31固定连接，则通过气缸或液压缸或电磁缸驱动，使得活塞杆进行直线往复运动，进而使得改变第一调节部31与第二调节部32之间的距离，相较于实施例1及实施例2螺纹调节的方式，实现自动调节第一调节部31与第二调节部32之间距离的目的。
实施例4
在实施例1或实施例2或实施例3所提供的方案的基础上，发明人对调节部件2的结构进行改进，具体请结合图6所示，其改进方案在于，第一活动件21与第二活动件22交错设置，且第一活动件21的一端铰接滑轮组件1，另一端铰接第二调节部32，第二活动件22的一端铰接滑轮组件1，另一端铰接第一调节部31。
具体的，第一活动件21一端铰接在第二调节部32上，另一端铰接在铰接件24靠近第一调节部31的一端上，第二活动件22一端铰接在第一调节部31上，另一端铰接在铰接件24靠近第二调节部32的一端上，则第一 活动件21与第二活动件22呈交错设置，则第一调节部31或第二调节部32沿着驱动杆33的方向相向或向背滑动时，仍可通过第一活动件21与第二活动件22对滑轮组件1进行牵拉或推动，进而实现调节第一调节部31与第二调节部32之间距离的效果。
除上述交错方式外，第一活动件21一端及第二活动件22一端分别对应铰接第二调节部32及第一调节部31，第一活动件21另一端及第二活动件22另一端均铰接在铰接件24上，且第一活动件21与第二活动件22铰接在铰接件24上的位置相同，优选的，第一活动件21与第二活动件22铰接在铰接件24上的位置优选在铰接件24的中间位置处。
实施例5
不同于实施例4所述的方案，本实施例在实施例1或者实施例2或者实施例3所提供的方案的基础上，具体请结合图7所示，发明人对调节部件2的结构进行改进的方案在于，调节部件2还包括固定件23，第一活动件21的一端与第二活动件22的一端均铰接固定件23的一端上，第一活动件21的另一端铰接第一调节部31，第二活动件22的另一端铰接第二调节部32，固定件23的另一端固定连接在滑轮组件1上，具体的，固定件23固定连接在铰接件24上，进而使得进行受力的第一活动件21及第二活动件22的长度减小，进而提高了第一活动件21及第二活动件22可承受载荷的能力。
本发明方案所公开的技术手段不仅限于上述实施方式所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
