Description
一种双向开合液压缓冲合页
技术领域
本发明涉及门窗配件领域, 特别是一种双向开合液压缓冲合页。
背景技术
目前, 很多的合页都具有缓冲功能。 其中, 现有缓冲大多由第一合页体、 第二合页体、 连接轴、 活动块、 弹簧、 定位套管、 外套管、 限位销构成, 在 定位套管上会开设有具有限位功能的限位导向孔。 在组装时, 弹簧套装于连 接轴上, 活动块活动连接在连接轴端部, 并使弹簧两端分别弹性作用在连接 轴与活动块上, 然后使活动块伸入至定位套管中, 并使限位销同时穿置于限 位导向孔与活动块上, 接着使外套管套装于连接轴、 活动块、 弹簧、 定位套 管上, 再接着使外套管两端分别穿置于第一合页体、 第二合页体上, 并使连 接轴端部与第一合页体相接, 还使定位套管与第二合页体相接。 这样在第一 合页体与第二合页体转动相互转动时, 活动块会相对定位套管转动, 并使限 位销在限位导向孔中滑动。 由于, 弹簧弹性作用在活动块上, 这样在没有外 力的作用下, 通过弹簧的弹簧就会推动限位销在限位导向孔中滑动, 然后通 过反向力, 就可以使连接轴实现转动, 从而就可使第一合页体与第二合页体 实现相对转动, 进而就可使门实现自动关闭的效果。 在此类缓冲合页中, 单 单通过弹簧的弹力使门实现自动关闭, 然而, 在长时间的使用下, 弹簧的弹 力极易出现失效的情况, 从而会导致合页的使用寿命降低。 且在此类活动转 动过程中, 易出现较大的噪音, 十分影响人们的生活。 虽然, 目前出现了带 有液压油的合页, 但由于现有合页结构设计的缺陷, 使得液压油在流程过程 中易出现乱流扰动的情况, 极大地影响了合页缓冲作用的稳定性, 其无法满

又进一步地, 为了使活动活塞凸轮与旋转连接轴简单、 可靠地连接一起, 所述活动活塞凸轮上还设有穿套孔, 该穿套孔与旋转连接轴相套接一起, 在 活动活塞凸轮的外表面上还设有贯通穿套孔的第二腰形孔, 该第二腰形孔中 还设有横穿旋转连接轴的链接活动销, 以使活动活塞凸轮与旋转连接轴组装
连接一起。
本发明的有益效果: 在本发明的设计中, 由于芯轴管体一端是套装在第 一密封连接件内端端部上的, 且第二密封连接件一端是嵌置于芯轴管体另一 端中的, 其第二密封连接件嵌置于芯轴管体中后, 可使芯轴管体内孔构成密 封的油腔。 而旋转连接轴一端、 活动活塞凸轮、 弹簧、 限位缸套都是位于该 油腔中, 这可以对这些结构起到遮蔽保护的作用, 且可降低噪音的产生与减 少各构件的磨损量, 这有有助于提高合页的使用寿命。 在活动活塞凸轮活动 过程中, 可以使活动活塞凸轮与固定凸轮部之间的空间实现扩大或缩小。 由 于, 第一密封连接件上开设有螺纹调节孔、 回油孔、 进油孔, 在组装完成后, 可在该合页上形成由进油孔、 螺纹调节孔、 回油孔、 导流槽、 油腔、 导油孔 构成的油路循环通道。 由于导油孔上设有单向阀, 可使油路循环通道只能实 现单向流动, 这样在活动活塞凸轮活动过程中, 就能推动液压油沿着油路循 环通道单向流动。 又由于螺纹调节孔中设有调节螺塞, 这样通过转动调节螺 塞, 可以调节进油孔孔口与回油孔孔口之间的螺纹咬合量, 当咬合量越大时, 液压油通过的螺纹咬合间隙就越多, 其实现的缓冲作用就越大。 当咬合量越 小, 液压油通过的螺纹咬合间隙就越少, 其实现的缓冲作用就越少。 这样就 可以起到调节缓冲作用力多大的目的。 由于进油孔孔口与回油孔孔口都位于 螺纹调节孔孔壁上, 这能使液压油更加平稳地顺着螺纹的咬合间隙流动, 能 够有效地避免乱流扰动的情况, 有助于提高合页的缓冲性能, 其能够完全满 足人们的使用需求。 同时, 还由于限位缸套上开设有呈字母 ‘V’ 字形状的限 位导向孔, 这样在弹簧的弹力作用下, 使得限位销只能停留在限位导向孔中 部, 这样合页可实现双向开合。 在应用时, 可使门既能相外开, 又能向内开,
而且当门扇打开到一定角度后, 能将门扇自动定位在一定角度上; 例如, 当 门扇打开到 45度角左右时, 门扇能自动打开定位到 90度角上, 或者, 当门 扇打开到大于 90度角后, 门扇能自动打开定位到 180度角上。 反之, 而当门 扇关闭到一定角度后, 能自动关闭上门扇。 并且在门扇关闭的过程中, 还具 有缓冲作用, 避免了门扇过重地撞击在门框上, 起到关门静音的效果。 而通 过活动活塞凸轮的活动凸轮部与固定凸轮部的配合, 可以与限位导向孔一起 起到双重的限位作用, 这有助于提高合页的可靠性。 该双向开合液压缓冲合 页的结构设计十分科学合理, 有助于提高合页的可靠性。

具体实施方式
如图 1、 图 2与图 4所示, 本发明所述的一种双向开合液压缓冲合页, 包 括第一合页体 1、 第二合页体 2、 芯轴装置 3 , 所述第一合页体 1与第二合页 体 2通过芯轴装置 3组装连接一起, 其特征在于: 所述芯轴装置 3包括芯轴 管体 31、 第一密封连接件 32、 第二密封连接件 33、 活动活塞凸轮 34、 限位
缸套 35、 旋转连接轴 36、 弹簧 37、 限位销 38、 单向阀 343。
其中,如图 5所示,所述第一密封连接件 32外端端部开设螺纹调节孔 321, 所述螺纹调节孔 321中设有调节螺塞 322 ,所述螺纹调节孔 321的孔壁两侧上 分别设有向外贯通布置的回油孔 301与进油孔 302 ,其中所述回油孔 301贯通 布置到第一密封连接件 32的外侧壁上, 所述进油孔 302贯通布置到第一密封 连接件 32的内端端面上, 在第一密封连接件 32的内端端面上还设有固定凸 轮部 323。此处的回油孔 301与进油孔 302的设计, 可以通过调节螺塞 322来 实现对整个油路运行时, 油流量的快慢, 以此来调节整个合页运行过程中的 油压。
如图 6与图 4所示, 所述活动活塞凸轮 34上设有与固定凸轮部 323相适 配作用的活动凸轮部 341, 在活动活塞凸轮 34上还设有由其一端贯通至其另 一端的导油孔 342。
如图 7与图 4所示, 所述限位缸套 35上设有由其一端贯通至其另一端的 定位导向孔 351, 在限位缸套 35的表面上还设有呈字母 ‘V’ 字形状的限位导 向孔 352 , 该限位导向孔 352与定位导向孔 351呈贯穿相通设置, 在限位缸套 35的表面上还设有沿其长度设置的导流槽 353。
如图 2与图 3所示, 所述限位缸套 35与第一密封连接件 32相套装固定 一起,且所述限位缸套 35上的导流槽 353与第一密封连接件 32的回油孔 301 相对接连通一起构成回油槽路; 所述活动活塞凸轮 34套装于限位缸套 35的 定位导向孔 351中, 且活动活塞凸轮 34上的活动凸轮部 341与第一密封连接 件 32的固定凸轮部 323相对接咬合一起, 在活动凸轮部 341 与固定凸轮部 323之间还设有供单向阀 343容置安装的腔孔 20 , 所述单向阀 343安装于腔
孔 20中; 在限位缸套 35与活动活塞凸轮 34之间还设有横向穿插设置的限位 销 38, 并限位销 38—端置于限位导向孔 352中, 以使活动活塞凸轮 34沿着 限位导向孔 352作轴向运动。 所述活动活塞凸轮 34与旋转连接轴 36的其中 一端相套装一起,所述弹簧 37套装于活动活塞凸轮 34与旋转连接轴 36之间, 以此来组装构成第一芯轴组件 4。
如图 3所示, 所述第一芯轴组件 4套装于芯轴管体 31的其中一端中, 并 使第一密封连接件 32置于芯轴管体 31的其中一端管口处, 以对芯轴管体 31 的其中一端管口形成密封封端作用;所述第二密封连接件 33与旋转连接轴 36 的另一端相连接, 并使第二密封连接件 33置于嵌置于芯轴管体 31的另一端 管口处, 以对芯轴管体 31的另一端管口形成密封封端作用, 以此来在芯轴管 体 31内形成两端封闭的密封油腔 311。
在本发明的设计中, 由于芯轴管体 31—端是套装在第一密封连接件 32 内端端部上的, 且第二密封连接件 33—端是嵌置于芯轴管体 31另一端中的, 其第二密封连接件 33嵌置于芯轴管体 31中后, 可使芯轴管体 31内孔构成密 封的油腔 311。 而旋转连接轴 36—端、 活动活塞凸轮 34、 弹簧 37、 限位缸套 35都是位于该油腔 311中, 这可以对这些结构起到遮蔽保护的作用, 且可降 低噪音的产生与减少各构件的磨损量, 这有有助于提高合页的使用寿命。 在 活动活塞凸轮 34活动过程中, 可以使活动活塞凸轮 34与固定凸轮部 323之 间的空间实现扩大或缩小。由于,第一密封连接件 32上开设有螺纹调节孔 321、 回油孔 301、 进油孔 302 , 在组装完成后, 可在该合页上形成由进油孔 302、 螺纹调节孔 321、 回油孔 301、 导流槽 353、 油腔 311、 导油孔 342构成的油 路循环通道。 由于, 导油孔 342上设有单向阀 343 , 可使油路循环通道只能实
现单向流动, 这样在活动活塞凸轮 34活动过程中, 就能推动液压油沿着油路 循环通道单向流动。 由于, 螺纹调节孔 321中设有调节螺塞 322 , 这样通过转 动调节螺塞 322 ,可以调节进油孔 302孔口与回油孔 301孔口之间的螺纹咬合 量, 当咬合量越大时, 液压油通过的螺纹咬合间隙就越多, 其实现的缓冲作 用就越大。 当咬合量越小, 液压油通过的螺纹咬合间隙就越少, 其实现的缓 冲作用就越少。 这样就可以起到调节缓冲作用力大多的目的。 由于, 进油孔 302孔口与回油孔 301孔口都位于螺纹调节孔 321孔壁上,这能使液压油更加 平稳地顺着螺纹的咬合间隙流动, 能够有效地避免乱流扰动的情况, 有助于 提高合页的缓冲性能, 其能够完全满足人们的使用需求。 同时, 由于, 限位 缸套 35上开设有呈字母 ‘V’ 字形状的限位导向孔 352 , 这样在弹簧 37的弹 力作用下, 使得限位销 38只能停留在限位导向孔 352中部, 这样合页可实现 双向开合。 在应用时, 可使门既能相外开, 又能向内开, 并能自动关闭, 在 关闭过程中, 还具有缓冲作用。 而通过活动活塞凸轮 34的活动凸轮部 341与 固定凸轮部 323的配合, 可以与限位导向孔 352—起起到双重的限位作用, 这有助于提高合页的可靠性。 该双向开合液压缓冲合页的结构设计十分科学 合理, 有助于提高合页的可靠性。
通过使活动活塞凸轮 34上的限位销 38运动轨迹与限位导向孔 352孔型 保持一致, 可以避免活动活塞凸轮 34与固定凸轮部 323相对转动时, 限位销 38出现卡滞的情况, 这有助于提高整体结构的可靠性。 在实际制造过程中, 为增强合页的密封性, 可根据需要在一些结构的连接处设置密封圈。
为了实现对弹簧 37张紧力的调节, 如图 8、 图 3、 图 4所示, 所述旋转 连接轴 36上还设有第一腰形孔 361, 在第一腰形孔 361中穿置有弹簧压力销
362 ,所述旋转连接轴 36的另一端端面上设有由其端面贯穿至第一腰形孔 361 的螺纹孔 363 , 所述螺纹孔 363中安装有调节螺杆 364, 并使调节螺杆 364的 内端顶在弹簧压力销 362的中部上, 所述弹簧 37套置于弹簧压力销 362与活 动活塞凸轮 34之间。 在使用过程中, 可通过转动调节螺杆 364推动弹簧压力 销 362 , 使其沿着第一腰形孔 361滑动, 这样可达到弹簧压力销 362改变作用 于弹簧 37上的压力的目的, 从而可改变活动活塞凸轮 34运动强度, 以达到 调节缓冲作用的目的。 该结构设计十分简单可靠。 通过这部分弹簧弹簧力度 的调节结构设计, 使本发明不仅能够通过油压调节来调节合页运行力度, 而 且还可以通过调节弹簧 37的张紧力度来调节合页运行力度, 具有双调节的功 能。
为了使活动活塞凸轮与旋转连接轴简单、可靠地连接一起, 如图 3与图 4 所示, 所述活动活塞凸轮 34上还设有穿套孔 344, 该穿套孔 344与旋转连接 轴 36相套接一起, 在活动活塞凸轮 34的外表面上还设有贯通穿套孔 344的 第二腰形孔 345 , 该第二腰形孔 345中还设有横穿旋转连接轴 36的链接活动 销 346, 以使活动活塞凸轮 34与旋转连接轴 36组装连接一起。通过这样的结 构设计, 有助于提高活动活塞凸轮 34与旋转连接轴 36连接结构的可靠性。
