Description

一种新型隐藏式液压合页 技术领域
本实用新型涉及电器领域，具体为一种新型隐藏式液压合页。
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。
请参见图1-3，CN211500247U公开了一种隐藏式液压合页，包括合页1以及分别固定在该合页1两侧的固定座2和门体连接部，其中固定座2固定在门框内部，而门体连接部固定在门体的内部，且该合页1为隐藏式设置，不会影响门体整体的美观，门体连接部包括导滑块3和液压装置，门体连接部的两侧均安装有连杆组件，该连杆组件的一端铰接在固定座2上，另一端铰接在液压装置上，因此合页1打开时，固定座2与液压装置会分离，此时会带动连杆组件移动；本实施例中，连杆组件分为曲杆6和连杆7，其中曲杆6的一端铰接在固定座2上，曲杆6与连杆7通过滚动轴承8铰接，且通过该滚动轴承8可带动曲杆6和连杆7移动，导滑块3上设有导向槽9，滚动轴承8置于该导向槽9内，该导向槽9上设有弧形导向面10，滚动轴承8可沿导向槽9滚动，且移动到一端时会沿弧形导向面10滚动到导向槽9的下端部，导滑块3上还设有止挡部11，当滚动轴承8沿弧形导向面10下落后，会抵靠在止挡部11处，此时滚动轴承8被限定，同时将门体限定；液压装置内安装有液压杆4，该液压杆4两侧对称设置有弹簧5，弹簧5的一端抵靠在导滑块3上，将弹簧5对称设置在液压杆4的两侧，相比于原来弹簧5需要套装在液 压杆4上的安装方式，这样的安装方式使得液压杆件4的长度可以缩短，且便于开孔安装，零件的制作与安装均有所优化；本实施例中，液压杆4的一端套装有端盖12，该端盖12的两侧对称固定有滑动柱13(铰接轴)，连杆7铰接在滑动柱13上，弹簧5置于该滑动柱13与导滑块3之间，当合页1打开时，曲杆6和连杆7会移动，此时连杆7带动滑动柱13与端盖12同步滑动，由于弹簧5的两端分别抵靠在导滑块3和滑动柱13上，因此在滑动柱13移动的同时会带动弹簧5以及液压杆4收缩；开门时，推动外部门体带动合页1翻转，通过连杆组件沿导滑块3滑动后将液压杆4与弹簧5收缩，且止挡部11可以定位门体，关门时，推动门体以克服止挡部11的阻力，将滚动轴承8推动回导向槽9内，此时滚动轴承8沿导向槽9反向运动，液压杆4与弹簧5展开会带动门体自动关闭，且液压杆4会起到缓冲作用，减速门体的关闭。
现有技术中，滚动轴承8与导向槽9之间的摩擦力大摩，合页转动过程不顺畅，同时由于曲杆6的活动范围需要合页1的宽度较大，导致门的开孔也宽会导致门的强度降低。
实用新型内容
本实用新型的目的在于提供一种新型隐藏式液压合页，转动顺畅，同时合页的宽度可以窄一些不影响门的强度。
为达到上述目的，本实用新型提供一种新型隐藏式液压合页，包括门体连接部、门框连接部、液压杆、连杆组件，该液压杆一端抵靠所述门体连接部，另一端与所述连杆组件铰接，该连杆组件包括与该门体连接部铰接的第一连杆、两端分别与该第一连杆背向所述门体连接部的一端、所述门框连接部铰接的第二连杆，该门框连接部铰接的第三连杆、两端分别与该第三连杆背向所述门框连接部的一端、所述门体连接部铰接的第四连杆，两端分别与该液压杆背向所述门体连接部的端部、所述第一连杆背向所述门体连接部的 一端连接的第五连杆，所述第二连杆与所述第四连杆中部铰接。
在本实用新型的一个实施例中，所述液压杆两侧对称设置有弹簧，所述弹簧的一端抵靠所述门体连接部；另一端抵靠所述第五连杆与所述液压杆的铰接轴。
在本实用新型的一个实施例中，所述液压杆背向所述门体连接部的端部设有端盖，所述第五连杆通过所述铰接轴与该端盖铰接。

在本实用新型的一个实施例中，当门关闭时所述第一连杆与所述第五连杆的夹角为15度-45度。
在本实用新型的一个实施例中，所述弹簧为压缩弹簧，所述第二连杆与所述第四连杆为弧形杆。

在本实用新型的一个实施例中，所述导向支架外固定有盖体，所述第五连杆穿过所述连杆铰接支架。
在本实用新型中，利用第一连杆、第二连杆、第三连杆、第四连杆、第五连杆组成连杆组，合页的转动顺畅，同时第五连杆的不需要穿过门框连接部第五连杆的铰接点靠近门体连接部侧，第五连接杆的摆动幅度小，合页的宽度可以窄一些不影响门的强度。
