Description

一种闭门器
技术领域
本发明涉及门体合页技术领域，特别是涉及一种闭门器。
背景技术
传统的门用合页为折合式合页，主合页与副合页铰接后固定安装于门框和门板上，不能对闭门起到缓冲作用，更不能控制闭门的速度。闭门时，若存在较大外力，门板与门框激烈碰撞发出较大声响，且激烈碰撞易造成门板与门框间过大的相互作用力，易对门板或门框造成损坏，影响门框和门板的使用寿命，且存在一定的安全隐患。为避免上述折合式合页的种种缺陷，市场上逐渐涌现出对闭门有缓冲作用的门用合页，即为闭门器。
然而，现有技术中的闭门器多采用直推式的缓冲器、单向阻尼器、螺旋式结构、液压机构来实现缓冲闭门。直推式的缓冲器需要在门上打孔安装，安装复杂，应用范围受限；单向阻尼器在闭门行程中的工作时间长、频繁次数的避门会达到单向阻尼器的寿命周期，而导致闭门缓冲功能的丧失；采用螺旋式结构的缓冲合页结构复杂，加工较困难，且无门停功能；现有的闭门器采用液压机构的缓冲合页往往存在漏油问题，且未设置门停功能。
发明内容
（一）要解决的技术问题。
本发明要解决的技术问题是提供一种闭门器，以克服现有技术中闭门器功能单一、无法对门体起到缓冲保护作用的问题。
（二）技术方案。
为解决上述技术问题，本发明提供一种闭门器，包括第一连接板和第二连接板，所述第一连接板和第二连接板铰接设置，所述第二连接板上固定有门体连接部，所述门体连接部用于连接外部的门体，所述第一连接板用于连接门框，所述门体连接部内安装有液压杆、连杆组件和复位弹簧，所述第一连接板上固定有连接座，所述连杆组件的一端穿过所述合页后固定在所述连接座上，所述第一连接板与所述第二连接板打开时会拉动所述连杆组件；所述门体连接部还包括壳体以及对称安装在所述壳体一端的导滑块，所述导滑块起到导向连杆组件滑动的作用，所述壳体的另一端固定有底座，所述液压杆、所述连杆组件和所述复位弹簧均安装在所述底座上，且所述液压杆和所述复位弹簧分别置于所述连杆组件的两侧；所述连杆组件分为曲杆、连杆和铰接座，所述铰接座安装在所述底座上，所述连杆铰接在所述铰接座上，所述曲杆的一端铰接在所述连杆上，所述曲杆的另一端连接所述连接座；开门时，外部门体带动所述第一连接板和所述第二连接板翻转，所述曲杆在所述第一连接板的作用下沿所述导滑块滑动，从而通过所述连杆拉动所述底座移动，进一步带动所述液压杆和所述复位弹簧收缩。
进一步的，所述曲杆与所述连杆的连接处对称安装有滚动轴承，所述导滑块上设有导向槽，所述滚动轴承置于所述导向槽内，所述导向槽上设有弧形导向面，所述导滑块上还设有定位凸台，所述定位凸台上设有圆弧面，起到了加强定位的作用，防止门体晃动，打门时，所述滚动轴承沿所述导向槽滑动，所述弧形导向面会带动所述滚动轴承向下偏移，从而卡在所述定位凸台上，起到了定位的作用，可将打开后的门体自动定位，通过外力克服所述定位凸台的限制后，可使所述滚动轴承回到导向槽内，此时复位弹簧带动合页复位，门体在合页的拉动下自动关闭，且液压杆可提供阻力，起到缓冲作用，避免门体碰撞损坏。
进一步的，所述导滑块内设有通孔，所述液压杆和所述复位弹簧的一端置于所述通孔内，所述第一连接板和所述第二连接板上对称设置有通槽，所述曲杆穿过所述通槽后连接在所述连接座上。
进一步的，所述曲杆的两端分别设有第一折弯部和第二折弯部，所述第一折弯部和所述第二折弯部分别连接所述连接座与所述连杆，所述液压杆上设有调速开关，所述调速开关可调节所述液压杆的伸缩速度，从而控制所述液压杆提供的阻力。
进一步的，所述液压杆的两侧均设有所述复位弹簧，所述连杆组件对称设置在所述壳体的两侧，所述壳体上设有第一腔体，所述第一腔体的两侧对称设有第二腔体，所述液压杆置于所述第一腔体内，所述复位弹簧置于所述第二腔体内，所述壳体上还设有滑槽，所述底座置于所述滑槽内。
进一步的，所述导滑块之间还设有第二导滑块，所述第二导滑块的两侧均设有所述导向槽。
（三）有益效果。
本发明一种闭门器，其第一连接板和第二连接板分别安装有连接座和门体连接部，且分别固定在门框和门体内，合页为隐藏式设置，不会影响门体美观，连接座与门体连接部之间通过连杆组件连接，门体在打开时会带动连杆移动，同时由连杆通过底座带动液压杆和弹簧收缩，导滑块上还设有用于定位的定位凸台，可将打开后的门体固定，关门时液压杆与弹簧展开可带动门体自动关闭。

参阅图1~图9，为解决上述技术问题，本发明提供一种闭门器，包括第一连接板3和第二连接板4，其中第二连接板4上固定有门体连接部，参阅图1和图2，门体连接部内安装有液压杆1、连杆组件和复位弹簧2，第一连接板3和第二连接板4铰接设置，第一连接板3上固定有连接座5，其中第一连接板3通过该连接座5连接门框，第二连接板4通过门体连接部连接外部门体，连杆组件的一端穿过第一连接板3和第二连接板4后固定在连接座5上，打开门体后第一连接板3和第二连接板4会带动连杆组件运动，连杆组件移动后带动液压杆1和复位弹簧2收缩。
参阅图2和图3，门体连接部还包括壳体6以及对称安装在该壳体6一端的导滑块7，导滑块7用于导向连杆组件滑动，本实施例中，该连杆组件分为曲杆9、连杆10和铰接座11，其中铰接座11安装在底座8上，连杆10铰接在铰接座11上，曲杆9的一端铰接在连杆10上，曲杆9的另一端连接连接座5，壳体6的另一端固定有底座8，且液压杆1、连杆组件和复位弹簧2均安装在底座8上，液压杆1和复位弹簧2分别置于连杆组件的两侧，当门体打开时，连接座5会带动曲杆9沿导滑块7滑动，从而带动连杆组件移动后，使底座8随之移动，底座8带动液压杆1和复位弹簧移动后收缩。
参阅图4~图9，本实施例中，曲杆9的两端分别设有第一折弯部18和第二折弯部19，其中第一折弯部18铰接在连接座5上，第二折弯部19连接连杆10，曲杆9与连杆10的连接处对称安装有滚动轴承12，导滑块7上设有导向槽13，滚动轴承12置于该导向槽13内，导向槽13上设有用于导向滑动的弧形导向面14，导滑块7上还设有定位凸台15，可限定滚动轴承12的位置，从而定位门体，该定位凸台15上还设有圆弧面，可提升定位凸台15的固定效果，避免门体晃动，开门时，曲杆9带动滚动轴承12在导向槽13内滑动，当滚动轴承12移动至弧形导向面14后，在弧形导向面14的引导下向下运动，使滚动轴承12卡在定位凸台15处，从而通过该滚动轴承12将打开后的门体定位，关门时，克服定位凸台15的阻力，可将滚动轴承12再次推动到导向槽13内，滚动轴承12在导向槽13内复位滚动，此时液压杆1与复位弹簧2复位，拉动连杆组件复位，从而通过连杆组件拉动门体自动关闭，且液压杆1提供了阻力，起到了缓冲的作用，避免门体移动过快而碰撞；本实施例中，液压杆1上设有调速开关20，可调节液压杆1的阻力，导滑块7内设有通孔16，液压杆1和复位弹簧2的一端置于通孔16内，第一连接板3和第二连接板4上对称设置有通槽17，曲杆9穿过该通槽17后铰接在连接座5上。
实施例二：
参阅图10~图12，本实施例与实施例一的区别在于：液压杆1的两侧均设有所述复位弹簧2，从而提升了关门时复位弹簧2的推力，有助于自动关闭门体，该壳体6上设有第一腔体21，第一腔体21的两侧对称设有第二腔体22，其中液压杆1置于第一腔体21内，复位弹簧2置于第二腔体22内，通过第一腔体21与第二腔体22可加强液压杆1和复位弹簧2的稳定性，避免复位过程中出现偏移；该壳体6上还设有滑槽23，底座8置于该滑槽23内，由于连杆组件对称设置在壳体6的两侧，且连杆组件底部连接底座8，通过连杆组件带动底座8运动，进而带动液压杆1和复位弹簧2收缩，因此滑槽23有助于底座8平稳滑动，使门体开闭更为流畅。
实施例三：
参阅图13和图14，本实施例与实施例一的区别在于：导滑块7之间还设有第二导滑块24，该第二导滑块24的两侧均设有导向槽13，通过设置有与导滑块7对应的导向槽13，使得滚动轴承12的运动轨迹更为平稳，进一步提高了门体开闭过程中的流畅性。
本发明一种闭门器，其中第一连接板与第二连接板的两侧分别安装有连接座和门体连接部，连接座和门体连接部分别固定在门框和门体内，且为隐藏式设置，不会影响门体美观，连接座与门体连接部之间通过连杆组件连接，门体连接部内还设有导滑块，可对连杆的移动起到导向作用，门体在打开时会带动连杆移动，同时由连杆通过底座带动液压杆和弹簧收缩，导滑块上还设有用于定位的定位凸台，可将打开后的门体固定，关门时液压杆与弹簧展开可带动门体自动关闭。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
