Description

一种新型磁扣

本发明涉及一种锁扣装置, 尤其涉及一种新型磁扣。
背景技术
作为一种锁扣装置, 磁扣系利用磁性元件(通常为磁铁) 的磁吸作用, 使分离的两个部件相扣合。 常见的磁扣通常包括公扣和母扣, 分别内设磁性 元件, 当公扣和母扣靠近时, 由于公扣内的磁性元件极性与母扣内的磁性元 件极性相反, 根据异性相吸的原理, 公扣与母扣相扣合。 分离时则需施加与 磁性元件吸力方向相反并且大于吸力的外力, 直接将公扣从母扣中拔出。 这 种磁扣结构虽然简单, 但操作不便, 尤其若需提高公扣和母扣的扣合紧密度 从而增加公扣内的磁性元件极性与母扣内的磁性元件之间的吸力时, 同样要 施加更大的力才能使公扣与母扣相分离。

具体实施方式
下面参考附图对本发明的优选实施例进行描述。
实施例一:
本发明实施例一提供一种新型磁扣, 包括第一扣件 1和第二扣件 2, 第 一扣件 1可分离地安装在所述第二扣件 2上, 第一扣件 1内设第一磁性元件 10, 第二扣件 2内并排相邻设置第二磁性元件 20a和第三磁性元件 20b, 第 二磁性元件 20a和第三磁性元件 20b可共同平行于第一磁性元件 10做直线 运动, 当第二磁性元件 20a与第一磁性元件 10相对时, 相对面的极性相反 以使第一扣件 1与第二扣件 2因第一磁性元件 10与第二磁性元件 20a的相 互吸引作用而扣合; 当第三磁性元件 20b与所述第一磁性元件 10相对时, 相对面的极性相同以使第一扣件 1与第二扣件 2因第一磁性元件 10与第三 磁性元件 20a的相互排斥作用而分离。
本发明实施例提供一种思路, 在第二磁性元件 20a的基础上, 在第二扣 件 2中增设一个第三磁性元件 20b, 并且与第二磁性元件 20a并排, 利用第 二磁性元件 20a和第三磁性元件 20b共同平行于第一磁性元件 10做直线运 动来使第一扣件 1与第二扣件 2相扣合或相分离。 具体来说, 当第一扣件 1 与第二扣件 2扣合时,如图 1所示, 第二磁性元件 20a相对第一磁性元件 10 运动到与之相对, 第一磁性元件 10与第二磁性元件 20a相对面的极性相反, 例如第一磁性元件 10朝向第二磁性元件 20a的面为 N极,第二磁性元件 20a 朝向第一磁性元件 10的面为 S极, 第一磁性元件 10与第二磁性元件 20a之 间产生吸力, 从而使第一扣件 1与第二扣件 2相扣合。 当第一扣件 1与第二 扣件 2分离时, 如图 2所示, 使第三磁性元件 20b相对第一磁性元件 10运 动(如图中箭头 R所示)到与之相对, 第一磁性元件 10与第三磁性元件 20b 相对面的极性相同, 例如第一磁性元件 10朝向第三磁性元件 20b的面为 N 极, 第三磁性元件 20b朝向第一磁性元件 10的面也为 N极, 第一磁性元件 10与第三磁性元件 20b之间产生排斥作用,从而使第一扣件 1与第二扣件 2 相分离。 由于在这个过程中, 第三磁性元件 20b平行于第一磁性元件 10作 直线运动, 其与第一磁性元件 10之间的排斥力逐渐增大, 与此同时, 第二 磁性元件 20a随之逐渐离开第一磁性元件 10,第二磁性元件 20a与第一磁性 元件 10之间的吸力逐渐减小, 因此, 本实施例中为使第一扣件 1与第二扣 件 2相分离而施加的外力明显小于磁性元件之间的磁力, 操作变得简便。
实施例二:
相对于实施例一, 本发明实施例二提供一种新型磁扣, 除了同样利用第 一磁性元件 10分别与第二磁性元件 20a、第三磁性元件 20b之间的相互作用 , 还增加了机械结构的改进, 同时通过机械结构的相应配合共同实现第一扣件 1与第二扣件 2的扣合和分离, 不仅增强了扣合的紧密度与稳定性, 操作的 便利性也得以进一步提升。
请参照图 3所示, 本发明实施例提供一种新型磁扣, 包括第一扣件 1和 第二扣件 2, 第一扣件 1可分离地安装在第二扣件 2上。
请结合图 4所示, 第一扣件 1从上至下包括面盖 12、 第一磁性元件 10 以及公扣 11 , 其中, 公扣 11包括顶板 110以及从顶板 110中部向下凸出的 凸台 111。 顶板 110为带圓角的矩形薄板。 凸台 111上宽下窄具有平行于顶 板 110的底面 112, 亦为带圓角的矩形, 面积远小于顶板 110。 底面 112在 顶板 110上的正投影位于顶板 110的中央。 凸台 111在顶板 110和底面 112 之间形成斜面 113 , 底面 112和斜面 113共同形成一容置空间(未图示), 用 于与面盖 12装配(面盖 12的结构将在后文详述)。 在底面 112—侧的斜面 113上设有第一窗口 114, 与该容置空间连通。
面盖 12包括盖板 120以及从盖板 120中部向下凸出的凸柱 121。 盖板 120为带圓角的矩形薄板, 大小与顶板 110相匹配。 凸柱 121为中空矩形柱 体, 垂直于盖板 120, 其在盖板 120上的正投影位于盖板 120的中央。 凸柱 121的底部为第一容纳腔 122, 用于容纳第一磁性元件 10。 凸柱 121的一侧 设有开口 123 , 当面盖 12与公扣 11装配时, 凸柱 121插入到凸台 111中, 第一窗口 114与开口 123连通。 具体地, 在面盖 12的盖板 120底面, 沿凸 柱 121设有凸棱 124,在公扣 11的顶板 110顶面对应设置有凹槽(未图示), 凸棱 124与凹槽通过干涉配合, 使面盖 12与公扣 11装配在一起, 当然, 此 时第一磁性元件 10容置在第一容纳腔 122中, 并被 4氐压在凸台 111的底面 112上。
为简化结构,第一扣件 1的公扣 11和面盖 12可以合二为一,一体成型, 包括内部为腔体结构的凸台 111 , 第一磁性元件 10则设置在凸台 111底部, 以便于与第二扣件 2中的第二磁性元件 20a和第三磁性元件 20b分别相对。 凸台 111侧面上设有第一窗口 114, 与内部腔体连通。
第二扣件 2包括一对第二磁性元件 20a、 20b、 上盖 21、 滑块组件 22、 限位摆杆 23、 滑动盒组件 24、 下盖 25以及开关底盖 26。 上盖 21尺寸比公 扣 11略大, 中部内凹形成形状与凸台 111相匹配的腔体 211 (上宽下窄), 用于容纳凸台 111。 腔体 211四周亦为斜面设计, 与凸台 111的斜面 113相 配合, 使得当第一扣件 1在磁力的带动下扣入第二扣件 2时, 凸台 111可以 从较大的腔体 211入口插入并紧密结合。 在腔体 211的斜面上, 对应于凸台 111的第一窗口 114的位置设有第二窗口(未图示), 该第二窗口与第一窗口 114、 开口 123相连通。
请再参照图 5所示, 滑块组件 22包括滑块 220和第一弹簧 221 , 滑块 220包括上下错开设置的插入块 222和底板 223 , 插入块 222—端为带斜面 的插入部 224, 在底板 223靠近插入部 224的一端, 垂直向下延伸形成挡板 225 , 在挡板 225顶部两侧的底板 223上, 分别内凹形成凹位 226。 在插入块 222的另一端内设一圓洞(未图示), 第一弹簧 221—端 4氐持在圓洞内, 另一 端固定于上盖 21。 第一弹簧 221给滑块 220施加水平方向的力, 使滑块 220 可以在水平方向移动。
再如图 6所示, 限位摆杆 23包括一对平行的 4氏压臂 230, 在 4氏压臂 230 的前端形成抵压部 231 , 用于与滑块 220的凹位 226相抵压。 抵压臂 230的 后端为一对共轴、 相向设置的安装轴 232以及连接杆 233 , 连接杆 233支撑 在抵压臂 230之间, 安装轴 232与连接杆 233横向和纵向均存在间隔, 其中 安装轴 232略低于连接杆 233 , 并且位于抵压臂 230的后端部。 扭簧 234两 端套设在安装轴 232上, 扭臂伸到连接杆 233下方, 用于给抵压臂 230施加 力以使抵压臂 230可以安装轴 232为旋转轴旋转。在抵压部 231和安装轴 232 之间, 抵压臂 230还设有一对相向设置的按压部 235 , 当按压部 235受到按 压时, 可以带动抵压臂 230尤其是抵压部 231向下运动。
当滑块组件 22与限位摆杆 23装配时, 如图 7所示, 抵压臂 230的抵压 部 231伸入插入部 224下方, 4氐压在滑块 220的凹位 226中。结合图 1所示, 此时扭簧 234给抵压臂 230施加的力使抵压部 231有顺时针运动的趋势(在 凹位 226中该力的方向为竖直向上),但滑块 22的底板 223及凹位 226阻挡 了这种趋势; 而第一弹簧 221 (未图示)处于压缩状态, 使滑块 220有水平 方向(结合图 3所示,为水平向右)移动的趋势,但抵压臂 230的抵压部 231 同样阻止了这种趋势, 于是, 滑块 220与限位摆杆 23能够通过这种相互抵 压而固定。
请参照图 8所示,滑动盒组件 24包括滑动盒 240和第二弹簧 242。滑动 盒 240包括并排的第二容纳腔 241a和第三容纳腔 241b, 用于分别容纳第二 磁性元件 20a和第三磁性元件 20b, 其中, 第二磁性元件 20a和第三磁性元 件 20b的极性设置相反,例如,第二磁性元件 20a朝上为 S极,朝下为 N极, 而第三磁性元件 20b则朝上为 N极, 朝下为 S极。 在容纳腔 241a、 241b下 方延伸设置凸块 243 , 本实施例中凸块 243为扁平状, 内设一螺管 244。 从 第二容纳腔 241a—侧沿水平方向延伸设置带阶梯位 246的抵压板 245 ,抵压 板 245与滑块 220的挡板 224的下沿相接。 在抵压板 245下方, 从凸块 243 一侧沿抵压板 245方向延伸设置有安装杆 247, 第二弹簧 242—端套设在安 装 4干 247上, 另一端固定于下盖 25。
下盖 25的形状与上盖 21相似,共同形成容纳空间 ,将第二磁性元件 20a、 第三磁性元件 20b、滑块组件 22、限位摆杆 23及滑动盒组件 24容纳在其中。
开关底盖 26可滑动地安装在下盖 25上, 其包括盖体 260和扣合在盖体 260上的开关面盖 261。 请再结合图 9所示, 盖体 260顶部向下凹设有收容 槽 263 ,轮廓与滑动盒 240的凸块 243相匹配,用于将凸块 243收容在其中。 螺钉 264穿过收容槽 263 ,插入到凸块 243的螺管 244中,与螺管 244螺合, 从而实现开关底盖 26与滑动盒 240的装配, 以使当开关底盖 26沿水平方向 在下盖 25中滑动时, 可以带动滑动盒 240做同向滑动。
图 10是本发明实施例新型磁扣装配后的立体结构示意图。 开关底盖 26 部分露出于下盖 25 ,通过沿水平方向拨动开关底盖 26, 可以实现第一扣件 1 与第二扣件 2的分离。
本实施例的新型磁扣还包括第一盖片 27和第二盖片 28, 第一盖片 27 与上盖 21相装配, 以将滑块组件 22和限位摆杆 23固定在上盖 21内, 第二 盖片 28与下盖 25相装配, 以将滑动盒组件 24固定在上盖 25内。
下面通过图 11-13 来说明本发明实施例新型磁扣扣合的工作原理及过 程。
图 11为本发明实施例新型磁扣的第一扣件 1与第二扣件 2相扣合的初 始状态示意图。 在这种状态下, 第二扣件 2中, 限位摆杆 23的抵压臂 230 伸入到滑块 220的插入块 222下方,抵压臂 230的抵压部 231抵压在滑块 220 的凹位 226中。此时扭簧 234给抵压臂 230施加的力使抵压部 231有顺时针 运动的趋势(在凹位 226中该力的方向为竖直向上), 而第一弹簧 221处于 压缩状态, 使滑块 220有水平方向 (图 11所示具体为水平向左)滑动的趋 势, 滑块 220与限位摆杆 23能够通过这种相互抵压而固定。 滑动盒组件 24 的第二弹簧 242处于自然状态, 未对滑动盒 240施加力, 滑动盒 240的 4氐压 板 245与滑块 220的挡板 225的下沿相接。滑动盒组件 24的第二容纳腔 241a 正对上盖 21的腔体 211底面, 为使第一扣件 1与第二扣件 2能因磁吸作用 而扣合, 容纳在第一容纳腔 122中并抵压在凸台 111的底面 112上的第一磁 性元件 10, 与容纳在第二容纳腔 241 a中的第二磁性元件 20a相对的面, 极 性应设置为相反, 以图 11为例, 第一磁性元件 10朝向第二扣件 2的一面为 N极, 而第二磁性元件 20a朝向第一扣件 1的一面为 S极。
图 12为本发明实施例新型磁扣的第一扣件 1与第二扣件 2相扣合的中 间状态示意图。 在这种状态下, 第一扣件 1受第一磁性元件 10与第二磁性 元件 20a的吸引作用,凸台 111滑入上盖 21的腔体 211 ,凸台 111的底面 112 抵压限位摆杆 23的按压部 235 ,对其施加向下的压力,该向下的压力大于扭 簧 234所施加的向上的压力, 因此滑块 220与限位摆杆 23之间的力平衡被 打破, 按压部 235带动抵压臂 230做顺时针方向运动, 抵压部 231也随之做 顺时针方向移动,部分地从滑块 220的凹位 226中脱出。 当第一磁性元件 10 与第二磁性元件 20a更加靠近, 磁吸作用更大, 按压部 235带动抵压臂 230 进一步向下移动, 4氐压部 231完全从滑块 220的凹位 226中脱出, 滑块 220 不再受到限位摆杆 23的限制,原本处于压缩状态的第一弹簧 221开始反弹, 带动滑块 220及其插入部 224向左方滑动。 而相应地, 由于第一扣件 1的凸 台 111在其斜面 113处设有第一窗口 114,上盖 21的腔体 211在其斜面上也 对应设有第二窗口, 滑块 220的插入部 224则依次穿过第二窗口、 第一窗口 114 以及凸柱 121上的开口 123 , 并固持在其中。 在这个过程中, 滑块 220 的挡板 225在滑动盒 240的抵压板 245上滑动 , 当插入部 224完成插入后 , 挡板 225与抵压板 245的阶梯位 246相接。 由此形成如图 13所示的第一扣 件 1与第二扣件 2扣合完成的状态。
从上可以看出, 第一扣件 1和第二扣件 2除了通过第一磁性元件 10和 第二磁性元件 20a的磁吸作用扣合以外, 还借由在这个磁吸过程中, 第二扣 件 2中的滑块 220滑动插入到第一扣件 1中的窗口并固持在其中, 实现第一 扣件 1和第二扣件 2的机械装配, 因此增加了扣合的稳定性, 并且整个过程 无需人工参与, 全部自动完成, 使用极为方便。
下面再通过图 14-15来说明本发明实施例新型磁扣分离的工作原理及过 程。
请参照图 14所示, 当实施第一扣件 1与第二扣件 2的分离操作时, 水 平向右 (如箭头 R所示)拨动开关底盖 26, 由于开关底盖 26与滑动盒 240 通过螺钉 264与螺管 244的螺合而装配在一起, 因此开关底盖 26的运动也 会带动滑动盒 240向右滑动。滑动盒 240上抵压板 245的阶梯位 246便对滑 块 220的挡板 225产生压力,推动挡板 225并进而带动滑块 220亦向右滑动。 滑块 220的滑动将使得其插入部 224逐渐从第一扣件 1的第一窗口 114中脱 出。 在这个过程中, 由于滑动盒 240的滑动, 使第二容纳腔 241a随之滑动, 第二磁性元件 20a与第一磁性元件 10由原先的正对逐渐错开, 磁吸作用逐 渐减小。
继续向右拨动开关底盖 26, 如图 15所示, 滑块 220的插入部 224从第 一扣件 1的第一窗口 114完全脱出, 第一扣件 1与第二扣件 2的机械装配解 除, 而滑动盒 240上的第三容纳腔 241b正好运动到正对上盖 21的腔体 211 底面, 即第三磁性元件 20b与第一磁性元件 10正对。 由于第三磁性元件 20b 朝上为 N极, 朝下为 S极, 而第一磁性元件 10朝上为 S极, 朝下为 N极, 因此其相对面的极性相同 (均为 N极), 第一磁性元件 10与第三磁性元件 20b之间受磁力作用相互排斥, 第一扣件 1被推出上盖 21。 在这个过程中, 由于第一磁性元件 10与第三磁性元件 20b之间的排斥作用, 第一扣件 1的 凸台 111施加在限位摆杆 23的按压部 235的压力减小, 扭簧 234施加在 4氐 压臂 230上的压力相对变大, 使抵压臂 230做逆时针运动, 抵压部 231向上 移动和从第一窗口 114中脱出的滑块 220的凹位 226相 4氐压, 滑块 220与限 位摆杆 23重新通过这种相互 4氐压而固定。 在滑动盒 240的滑动过程中, 套 设在安装杆 247上的第二弹簧 242受压处于压缩状态,其存在一个与拨动开 关底盖 26方向相反的反弹力(即水平向左), 当第一扣件 1与第二扣件 2分 离后, 松开开关底盖 26, 此反弹力使滑动盒 240 (带动开关底盖 26 )回弹至 如图 11所示的初始位置。
由上可知,在对本发明实施例新型磁扣的第一扣件 1和第二扣件 2进行 分离操作时, 只需拨动开关底盖 26, 带动滑块 220从第一扣件 1中脱出, 解 除了第一扣件 1与第二扣件 2的机械装配, 并且借由第三磁性元件 20b与第 一磁性元件 10的相互排斥作用, 自动将第一扣件 1从第二扣件 2推出。 因 此, 即使在对本发明实施例新型磁扣的扣合稳定度增强, 但分离时操作亦很 简单和方便。
本发明实施例中, 第一磁性元件 10、第二磁性元件 20a和第三磁性元件 20b均为磁铁。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明 之权利范围, 因此依本发明权利要求所作的等同变化, 仍属本发明所涵盖的 范围。
