Description

一种具有缓冲复位及按压反弹打开功能的抽屉导轨 技术领域
本发明涉及一种五金配件，具体是一种具有缓冲复位及按压反弹打开功能的抽屉导轨。
背景技术
目前，各种办公桌的抽屉都安装了滑动自如的抽屉导轨。为了使抽屉关闭后能紧贴办公桌，显得整齐美观。现有技术的方法是采用国际通用设计的自关角度型导轨，在固定轨的后端设有一段向下稍微倾斜的导轨，让装在抽屉上的滑动轨的前滚轮行走至倾斜段时在自重的作用下自动往下滑，从而保证抽屉完全关闭。然而，这种自关角度型导轨一直存在如下不足之处：1、当滑动轨的滚轮推至下滑端时，单靠抽屉的自重使滚轮只有3.5度至5度的斜面下滑，下滑关闭不明显，使用效果非常不理想；2、由于弯曲的角度小，当抽屉向外略有倾斜，就有滑出而掉地的情况；3、由于结构的原因，固定滑轨弯曲时，在弯曲点不可能连接平顺，因此抽屉推拉时，总有上坡后下坡的感觉，这样难于满足用户的要求；4、由于抽屉没有自锁功能，在搬动桌子时，抽屉容易在自重作用下滑移出来，造成搬动不方便。
发明内容
本发明的目的是为了克服已有技术存在的缺点，提供一种结构简单，使用方便，能在导轨关闭后具有锁定功能的一种具有缓冲复位及按压反弹打开功能的抽屉导轨。

所述的导向轨上还前后滑动式安装在有反弹滑块，反弹滑块与滑动座之间设置有反弹拉簧始终向导轨打开方向拉动反弹滑块；所述的反弹滑块的上还摆动式铰接安装有挂针块及拨针块，挂针块另一端设置有挂针位于滑动座内的挂针槽内运动，拨针块另外一端设置有拨针位于缓冲架上的自锁槽及复位槽内滑动；
所述的缓冲架上还摆动式铰接安装有主扣板，主扣板的上端面上设置有主扣柱位于缓冲架上的主扣槽内摆动，主扣板的下端面设置有驱动柱位于导向轨上的副扣槽内滑动；
所述的内轨的底部从后往前依次设置有推动扣、反弹扣、及复位扣，推动扣及复位扣与 主扣柱挂扣或分离，推动缓冲架相对滑动座运动，所述的反弹扣与拨针挂扣或分离。
所述的复位扣的下端面设置有复位扣槽，复位扣槽呈C型设置，主扣柱挂与该复位扣槽挂扣或是分离。
所述的推动扣截面呈梯形状，其两侧设置有导向斜面，推动扣通过其两侧的导向斜面与主扣柱挂的柱面接触，迫使其产生侧向推力。
所述的反弹扣上设置有反弹扣槽，反弹扣槽与拨针挂扣或是分离。
所述的自锁槽及复位槽与导轨的运行方向平行设置，自锁槽与复位槽间通过斜向设置有脱扣槽连接。

具体实施方式
下面结合附图对本发明作具体进一步的说明。一种具有缓冲复位及按压反弹打开功能的抽屉导轨，其包括由内至外依次包覆的内轨1，中轨2及外轨3，相邻两轨道间通过滚珠机构连接，使得相邻两轨道可相互滑动，其特征在于：所述的外轨3的尾端固定安装有滑动座4，滑动座4上设置有导向轨41，一缓冲架5前后滑动式安装在该导向轨41，所述的滑动座4与缓冲架5间设置有复位拉簧6及阻尼器7，复位拉簧6产生拉力始终向关闭方向拉动缓冲架5；
所述的导向轨41上还前后滑动式安装在有反弹滑块8，反弹滑块8与滑动座4之间设置有反弹拉簧81始终向导轨打开方向拉动反弹滑块8；所述的反弹滑块8的上还摆动式铰接安装有挂针块82及拨针块83，挂针块82另一端设置有挂针84位于滑动座4内的挂针槽42内运动，拨针块83另外一端设置有拨针85位于缓冲架5上的自锁槽51及复位槽52内滑动；
所述的缓冲架5上还摆动式铰接安装有主扣板86，主扣板86的上端面上设置有主扣柱87位于缓冲架5上的主扣槽53内摆动，主扣板86的下端面设置有驱动柱88位于导向轨41上的副扣槽43内滑动；
所述的内轨1的底部从后往前依次设置有推动扣9、反弹扣10、及复位扣11，推动扣9及复位扣11与主扣柱87挂扣或分离，推动缓冲架5相对滑动座4运动，所述的反弹扣10与拨针挂扣或分离。
所述的复位扣11的下端面设置有复位扣槽111，复位扣槽111呈C型设置，主扣柱87挂与该复位扣槽111挂扣或是分离。
所述的推动扣9截面呈梯形状，其两侧设置有导向斜面91，推动扣9通过其两侧的导向斜面91与主扣柱87挂的柱面接触，迫使其产生侧向推力。
所述的反弹扣10上设置有反弹扣槽101，反弹扣槽101与拨针85挂扣或是分离。
所述的自锁槽51及复位槽52与导轨的运行方向平行设置，自锁槽51与复位槽52间通过斜向设置有脱扣槽54连接。
所述的副扣槽43与导轨打开方向平行设置，其头围两端设置有朝向相反且斜向向外设置的脱离槽431，主扣槽53与脱离槽431呈Z字型分布设置。
工作原理：如图3所示，当导轨关闭时，缓冲架位于滑动座的最尾端，两者相对位置处于最小状态，同时，反弹滑块8尾端的挂针挂扣在滑动座尾端的挂针槽内，此时的内轨 被反弹滑块上的反弹扣槽101所扣死，因此当抽屉本体移动时，抽屉不会在没有外力的操作下而打开，保持了抽屉关闭后的密闭性。
如图4所示，当需要打开导轨时，向内按压内轨，内轨通过其上的反弹扣10推动反弹滑块8上的拨针85向后运动，迫使反弹滑块推动挂针向后运动，使得挂针与挂针槽脱离。此时，设置在反弹滑块与滑动座4间的反弹拉簧81拉动反弹滑块向导轨打开方向运动。其中，由于内轨通过反弹扣10上的反弹扣槽101与反弹滑块8上的拨针85挂扣，因此，反弹滑块向外运动时，势必会推动内轨向外打开，从而实现了抽屉导轨的按压反弹打开功能。因此，用户在操作安装有本导轨的抽屉时，轻按抽屉本体后，内置的反弹机构即可将抽屉弹出一段行程，提升用户操作质感。
如图6所示，当反弹滑块向外运动的过程中，拨针85由自锁槽51向复位槽52方向运动，其中，由于复位槽52的轨迹与自锁槽51的轨迹间有横向差，因此，当拨针85运行至复位槽52时，拨针与反弹扣槽101分离，内轨得以继续打开。当反弹结束后，用户即可向外拖动导轨使其完全打开。在导轨完全打开时，位于内轨尾端的推动扣9与主扣柱87挂扣，利用内轨向外运动的动力拉动反弹架向外打开。
如图7所示，当导轨打开到一定程度时，推动扣9通过主扣柱87拉动反弹架打开至最大程度，此时，主扣柱87下端的驱动柱88从导向轨41上的副扣槽43滑动自脱离槽431内并锁定缓冲架，使得主扣柱87发生横向移动，主扣柱87与推动扣9分离，内轨得以完全打开。缓冲架打开后，位于缓冲架与滑动座之间的拉簧被拉伸，产生复位动力。
如图8、9、10所示，当导轨关闭时，内轨上的复位扣11的下端面设置的复位扣槽111与主扣柱87相互碰撞，迫使主扣柱87从脱离槽431内脱落进入副扣槽43内，主扣柱87偏转过程中，与复位扣槽111挂扣，于此同时，拨针与反弹扣槽101挂扣，缓冲架解除锁定，在复位拉簧6及阻尼器7的作用下，拉动内轨缓慢关闭，实现抽屉导轨关闭时的缓冲复位功能。从而避免传统抽屉导轨关闭时，抽屉面板与抽屉本体间发生撞击而产生工作噪音。
与传统技术相比，本案中的缓冲架两侧均设置有复位拉簧，因此缓冲架工作时，缓冲架两侧均匀受到拉力，能够使得缓冲架运动顺畅稳定，同时，双拉簧的设计可为缓冲复位提供足够的动力，使其能够装配重型或是大型的抽屉使用。
进一步地：本案在的反弹滑块具备了对内轨关闭时的锁止作用，及反弹时推动内轨向外打开的作用，两项功能集合在于其上，与传统技术相比，本案在的结构更为简单紧凑，集成度高，有利于抽屉导轨向小型化方向发展，一改变传统缓冲复位导轨体积庞大，结构复 杂，外形臃肿等技术缺陷。
进一步地：与传统的抽屉导轨相比，由于本案中的结构可实现了抽屉的缓冲复位功能，可避免了传统无缓冲功能的导轨存在的关闭时噪音大，限位部件长期受到撞击容易导致部件损坏等弊端。同时，关闭后的抽屉受到反弹滑块的限制，可使其保持关闭的状态，避免抽屉在非外力操作的情况下打开，保证了抽屉关闭后美观整洁。另外，独特的反弹式开启结构，在方便用户操作的同时，由于采用了反弹拉簧启动，使其具有较大的开启行程。同时，反弹拉簧及其释放、锁止结构简单，动作高效，可提供较大的弹力供重型、大型抽屉使用，从而提升其适用范围，使其独具市场竞争力，故可广泛推广使用。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。
