Description

一种高防护无孔传动自锁装置 技术领域
本发明属于插座技术领域，涉及一种高防护无孔传动自锁装置。
背景技术
家庭中一般都会设置多个插座，通过插座的设置，方便各式电器产品的使用，为了提高插座的安全性，一般会在插座的插孔处设置保护门。
现有的带保护门的插座，例如中国专利文献资料公开了一种带保护门的插座[申请号：200720120219.0；授权公告号：CN201044291Y]，包括上盖和连接在上盖下端的保护门装置，其中上盖上包括两电极孔，保护门装置包括置于两电极孔内侧孔口的两个保护门，保护门装置包括连接在上盖的前盖和后盖，两个保护门为块体，两今保护门相向的端面均连接着门轴，两个保护门之前设有一扭簧，扭簧的两端分期压在两个保护门上，致两个保护门紧贴两电极孔内侧，扭簧套穿在设置在后盖上、与保护门平行的扭簧轴上，门轴由后盖定位在前盖的底面上。
该种结构的插座，插头的两个插片同时插入到插孔中，插片使两个保护门转动并嵌入到插套中，实现电联接，在插入的过程中，需要施加一定的外力，通过保护门起到保护的作用。但是在家庭中设置插座，幼童存在使用一根尖锐的物品插入到插孔中的问题，尖锐的物品接触保护门继续被推动会使保护门转动，使尖锐的物品嵌入到插套中，导致电会通过尖锐的物品传递到幼童的身体，容易发生触电危险，即该种结构的插座，当施加的外力大于扭簧的扭力时，保护门依然会转动被打开，存在误操作的问题， 插座的安全性不够高。
发明内容
本发明的目的是针对现有技术中存在的上述问题，提出了一种高防护无孔传动自锁装置，解决的技术问题是如何提高插座的安全性。
本发明的目的可通过下列技术方案来实现：一种高防护无孔传动自锁装置，包括具有插孔的基座以及位于基座中的一对转动块和第一复位件，在所述第一复位件的作用下所述转动块始终具有封堵对应插孔的趋势，其特征在于，所述基座中还设有滑动架和第二复位件，所述第二复位件的两端分别作用在基座和滑动架上，每个所述转动块与滑动架之间均设有联动结构和锁止结构，当一对所述转动块均受力转动时通过联动结构能使滑动架克服第二复位件移动，所述第一复位件和第二复位件相配合能使滑动架和转动块回复原位，当只有一个转动块受力时与另一个转动块相对设置的锁止结构会锁定滑动架并使受力的转动块无法继续转动。
第一复位件能使转动块封堵插孔，当插头的两个插片插入到插孔中，插片克服第一复位件的作用力使两个转动块同时旋转，转动块通过联动结构使滑动架克服第二复位件移动，从而使插片穿过插孔并推开转动块插入到插套中，插片拔出插套时，第一复位件和第二复位件相配合能使滑动架和转动块回复原位。当只有一个转动块受力时，该转动块会带动滑动架滑动很小的距离，随后与另一个转动块相对设置的锁止结构工作，在该锁止结构的作用下锁定滑动架，使另一个转动块和滑动架相锁死，使滑动架不会移动，滑动架不会移动从而使受力的转动块无法继续转动，实现自锁，使尖锐的物品不能穿过插孔，不会与插套接触，避免触电，提高插座的安全性。
在上述的一种高防护无孔传动自锁装置中，所述联动结构包 括所述转动块上凸出设置的且呈螺旋状的联动条和所述滑动架中凹入设置的联动槽，所述联动条嵌入设置在对应的联动槽中，所述联动条旋转能与联动槽的第一槽壁相抵靠并推动滑动架克服第二复位件的作用力移动。转动块受力转动时，联动条随转动块旋转，联动条旋转会接触滑动架并推动滑动架克服第二复位件的作用力移动，从而使插片可以穿过插孔并插入到插套中；而且联动条呈螺旋状，使转动块和滑动架相对运动的更加的顺畅，不会存在卡住的问题。在实际生产中，也可以将联动条设置在滑动架上，将联动槽设置在转动块上。
在上述的一种高防护无孔传动自锁装置中，所述锁止结构包括转动块上凹入设置的锁止槽和所述滑动架中凸出设置的锁止块，所述锁止块沿滑动架的移动方向与锁止槽之间具有设定的间距，当一个转动块受力旋转带动滑动架移动设定的间距后，位于另一个转动块处的锁止块嵌入到对应的锁止槽中锁定滑动架并使受力的转动块无法继续转动。锁止块沿滑动架的移动方向与锁止槽之间具有设定的间距，该间距的设置使一对转动块同时受力时，锁止槽可以越过锁止块，使锁止块不会嵌入到锁止槽中，从而使转动块能带动滑动架移动；同时该间距的设置，当一个转动块受力旋转带动滑动架移动设定的间距后，位于另一个转动块处的锁止块会嵌入到对应的锁止槽中，使另一个转动块和滑动架相互卡死，使滑动架锁定，滑动架锁定即可反作用在受力的转动块上，使受力的转动块无法继续转动，使尖锐的物品不能穿过插孔，提高插座的安全性。在实际生产中，也可以将锁止槽设置在滑动架上，将锁止块设置在转动块上。

在上述的一种高防护无孔传动自锁装置中，所述锁止部位于联动条靠近联动槽的端部。该种结构，当只有一个转动块受力时，另一个锁止部可以更快的嵌入到对应的锁止槽中，使转动块偏转的角度更小，使尖锐的物品不能插入，提高安全性。
在上述的一种高防护无孔传动自锁装置中，所述滑动架中具有贯穿滑动架端部的避让孔，所述避让孔沿滑动架移动方向的长度小于插孔沿滑动架移动方向的长度。该种结构的避让孔，使滑动架不会阻碍插头插入的同时保证滑动架的强度。

基座2具有插孔1，本实施例以两个插孔1为例，转动块3的数量为两个，插孔1和转动块3一一对应设置。本实施例中，第一复位件4为扭簧，第二复位件6为圆柱弹簧，在实际生产中，第一复位件4为弹片，第二复位件6为拉簧。
如图3所示，转动块3一侧的两端均具有凸出设置的转轴，转轴嵌入到基座2中使转动块3可以旋转，第一复位件4套在其中一根转轴外，第一复位件4的一端作用在基座2上，另一端作用在转动块3上，在第一复位件4的作用下转动块3始终具有封 堵对应插孔1的趋势。
每个转动块3与滑动架5之间均设有联动结构7和锁止结构8，如图4、图5所示，联动结构7包括转动块3上凸出设置的且呈螺旋状的联动条71和滑动架5中凹入设置的联动槽72，联动条71嵌入设置在对应的联动槽72中，联动条71旋转能与联动槽72的第一槽壁73相抵靠并推动滑动架5克服第二复位件6的作用力移动。锁止结构8包括转动块3上凹入设置的锁止槽81和滑动架5中凸出设置的锁止块82，锁止块82沿滑动架5的移动方向与锁止槽81之间具有设定的间距。具体来说，联动条71的一侧具有凸出设置的锁止部83，锁止部83与联动条71之间形成锁止槽81，锁止块82位于联动槽72中，锁止块82与联动槽72的第一槽壁73之间具有供联动条71穿过的通道。本实施例中，转动块3上具有凸出设置的呈长条状的封堵部31，在第一复位件4的作用下封堵部31能嵌入到对应的插孔1中，封堵部31的长度方向与转动块3的转动轴向相同，封堵部31长度方向的两侧与插孔1的孔壁之间均具有间隙，在实际生产中，转动块3上具有凸出设置的呈圆柱状的封堵部31，在第一复位件4的作用下封堵部31能嵌入到对应的插孔1中，封堵部31的外周壁与插孔1的孔壁之间具有间隙。
滑动架5和第二复位件6位于基座2中，第二复位件6的两端分别作用在基座2和滑动架5上。具体来说，基座2包括一对凸出设置的限位柱21，滑动架5和第二复位件6均位于一对限位柱21之间，滑动架5的底部具有导向槽52，基座2包括凸出设置的导向条22，导向条22部分嵌入设置在导向槽52中，滑动架5能沿着导向条22滑动。第二复位件6的一端作用在滑动架5上，另一端作用在其中一根限位柱21上，在第二复位件6的作用下，滑动架5始终具有沿着导向条22滑动并抵靠在另一根限位柱21上的趋势。滑动架5中具有贯穿滑动架5端部的避让孔51，避让 孔51沿滑动架5移动方向的长度小于插孔1沿滑动架5移动方向的长度。
工作时，插头的两个插片插入到插孔1中，插头抵靠在封堵部31上并推动转动块3克服第一复位件4的作用力转动，转动块3转动带动联动条71旋转，联动条71接触联动槽72的第一槽壁73并推动滑动架5克服第二复位件6的作用力沿着导向条22移动，在该过程中，锁止槽81越过锁止块82，锁止槽81和锁止块82不会卡接，从而使插片穿过插孔1并推开转动块3插入到插套中，实现电联接，插片拔出插套时，在第一复位件4和第二复位件6相配合的作用下使滑动架5和转动块3回复原位。当只有一个尖锐的物品抵靠在封堵部31上时，由于锁止块82沿滑动架5的移动方向与锁止槽81之间具有设定的间距，该间距的存在会使转动块3转动设定的距离，随后另一个转动块3处的锁止块82嵌入到对应的锁止槽81中，使另一个转动块3和滑动架5相互卡死，使滑动架5锁定，滑动架5锁定即可反作用在受力的转动块3上，使受力的转动块3无法继续转动，即受力的封堵部31依然位于插孔1中，使尖锐的物品不能穿过插孔1。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了插孔1、基座2、限位柱21、导向条22、转动块3、封堵部31、第一复位件4、滑动架5、避让孔51、导向槽52、第二复位件6、联动结构7、联动条71、联动槽72、第一槽壁73、锁止结构8、锁止槽81、锁止块82、锁止部83等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本发明的本质；把它们解释成任何一种附加的限制都是与本发明精神相违背的。
