Description

说明书 一种用在立柱的滑动装置
技术领域
[1] 本发明涉及一种用在立柱的滑动装置， 尤其涉及一种用在折叠帐篷类产品的立 柱的滑动装置。
背景技术
[2] 帐篷的立柱上大都滑动设置有一滑动装置， 该滑动装置用以连接帐篷的其它零 部件。 该立柱例如为在帐篷中起支撑作用的支腿立柱， 或， 如某些帐篷顶部中 心的顶部立柱。 该立柱大都为管件， 它上开设有一贯穿内外的锁接孔。 早期的 滑动装置包括一滑动座、 一插销、 一弹性体和一拉环。 该滑动座上开设有一滑 动通孔和一贯穿内外的安装孔， 该滑动通孔滑动套设在立柱之外， 该安装孔与 滑动通孔垂直相交并相通。 该插销装设在安装孔内并在第一位置和第二位置之 间水平滑动， 在第一位置吋插销伸进滑动通孔并插接进锁接孔， 在第二位置吋 插销缩进安装孔且滑动座能自由滑动。 该弹性体连接插销和滑动座， 并产生有 一使插销受顶抵并保持在第一位置的弹力。 该拉环连接在插销露出安装孔之外 的外端。 该滑动装置如美国专利数据库在 2003年 1月 21日公告的发明名称为 《折 叠帐篷架》 的发明专利， 它的专利号为 US6508262B1。 该滑动装置存在有如下不 足： 使用过程中， 用户需要一手拉动拉环克服弹性体弹力带动插销脱离出锁接 孔以能自由滑动的滑动座， 另一手抓住滑动座并相对立柱滑动， 由于需要两手 同吋操作， 因此给用户使用带来了极大的不便。
[3] 针对上述的不足， 有人提出了一种解决方案： 该滑动装置包括一滑动座 2、 一 插销、 一弹性体和一按钮。 该滑动座上开设有一滑动通孔和一贯穿内外的安装 孔， 该滑动通孔滑动套设在立柱之外， 该安装孔与滑动通孔垂直相交并相通。 该插销装设在安装孔内并在第一位置和第二位置之间活动， 在第一位置吋插销 伸进滑动通孔并插接进锁接孔， 在第二位置吋插销缩进安装孔且滑动座能自由 滑动。 该按钮包括一中部和分别位于中部之前后的一拉接端和一按钮部， 该中 部枢接在滑动座， 该拉接端枢接插销， 该按钮部供用户按压。 该弹性体装设在 按钮的按钮部背面和滑动座之间。 使用过程中， 用户一手握住滑动座并用该手 的手指按压按钮， 克服弹性体弹力带动按钮相对轴线转动， 带动拉接端绕轴线 转动， 带动插销的外端相对轴线向外转动， 带动带动插销脱离出锁接孔以实现 自由滑动滑动座， 此吋该握住滑动座的手即可带动滑动座相对立柱滑动。 该该 滑动装置例如中国专利数据库公告的 ZL200420014929.1、 200720006655.5的两个 专利。 该装置虽然解决了上述的不足， 用户釆用一手即可完成操作， 但是它还 存在有如下的不足：
其一、 由于插销的拉接端活动轨迹为圆弧， 因此插销的活动轨迹并不是一种简 单水平滑动， 而是一种复杂的曲线轨迹， 于是： 1、 为了保证插销的内端部能够 插入锁接孔， 该锁接孔的孔径必须大于插销的外径， 这使得滑动座的定位锁接 状态不稳定、 不牢固， 即使在定位锁接状态中该滑动座还能相对立柱做微小的 滑动， 该滑动距离为锁接孔的孔径和插销的外径之差； 2、 插销插接轨迹也为复 杂轨迹， 插接不便， 容易出现卡死现象；
[5] 其二， 弹性体装设在按钮部背面和滑动座之间， 由于该位置没有设置定位柱 （ 用于供弹性体套接） ， 因此弹性体无法定位， 复位吋容易扭歪， 使用不便， 寿 命不长； 即使设置了定位柱， 由于定位柱活动也为复杂曲线， 因此弹性体张紧 、 压缩过程中同样会扭歪；
[6] 其三， 由于弹簧设置在按纽按压部， 常态下， 弹簧需要先施力于按纽， 再由按 纽传递至插销， 来保证插销位于第一位置， 因此定位效果差。 且， 按压按纽吋 需要直接对弹簧施力， 由于使用者用力大小不一， 很容易压坏弹簧使其失去弹 性， 而无法锁接定位。
发明内容
[7] 本发明提供一种用在立柱的滑动装置， 它克服了背景技术滑动装置所存在的使 用不便、 锁接定位不稳定的不足。
[8] 本发明解决其技术问题所釆用的技术方案是：
[9] 一种用在立柱的滑动装置， 它滑动装设在立柱， 该立柱上开设有锁接孔， 该滑 动装置包括：
[10] 一滑动座， 它上开设有一滑动通孔和一安装孔， 该滑动通孔滑动套设在立柱之 夕卜， 该安装孔与滑动通孔垂直相交并相通；
[11] 一插销， 它装设在安装孔内并在第一位置和第二位置之间水平滑动， 在第一位 置吋插销伸进滑动通孔并插接进锁接孔， 在第二位置吋插销缩进安装孔；
[12] 一弹性体， 它连接插销和滑动座， 该弹性体产生有一使插销受顶抵并保持在第 一位置的弹力； 以及
[13] 一按钮， 它装设在滑动座并与滑动座构成能相对转动和相对滑动的活动连接关 系， 该按钮具有一枢接插销的拉接端和一供用户按压的按钮部。
[14] 本发明的一较佳实施例中， 该滑动座之上凸设有一后壁； 该按钮部凸设在按钮 之上， 它具有一在按压到底后平行立柱的、 齐平后壁末端面的按钮面。
[15] 本发明的一较佳实施例中， 该安装孔为内外贯穿的、 内小外大的阶梯孔， 它具 有一外大孔和一内小孔； 该插销具有一内端部和一外端部， 该内端部与锁接孔
、 内小孔匹配， 该外端部与按钮的拉接端枢接。
[16] 本发明的一较佳实施例中， 该滑动座上开设有安装槽； 该按钮上设有定位轴， 该定位轴装设在安装槽之内并与安装槽构成能相对转动和相对滑动的活动连接 关系。
[17] 本发明的一较佳实施例中， 该安装槽内径大于定位轴外径。
[18] 本发明的一较佳实施例中， 该安装槽为腰形槽， 该定位轴能转动、 滑动连接在 安装槽之内。
[19] 本发明的一较佳实施例中， 该按钮中部上下各向外凸设形成有凸柱， 该凸柱为 定位轴； 该拉接端和按钮部分别设置在凸柱之前后。
[20] 本发明的一较佳实施例中， 该安装槽带有朝后或朝上的开口， 该开口小于定位 轴外径。
[21] 本发明的一较佳实施例中， 该插销中部向外凸设形成有凸起环； 该滑动座的安 装孔的外大孔之内固设有一定位套， 它外端口向内延伸形成环体盖； 该插销外 端部伸出环体盖之外并枢接按钮的拉接端； 该弹性体为弹簧， 它套设在插销之 外并顶抵凸起环和环体盖。
[22] 本发明的一较佳实施例中， 该滑动座上开设有一安装槽， 该按钮穿过安装槽， 而且， 该安装槽的间隙大于按钮的厚度。 [23] 本技术方案与背景技术相比： 针对背景技术存在的不足， 本申请人设计出了一 种全新的技术方案， 利用按钮按压实现单手操作， 利用插销水平滑动实现微小 间隙 （微小间隙远小于背景技术的间隙） 的牢固定位锁接， 利用按钮和滑动座 之间的同吋相对转动和相对滑动的活动连接关系实现用户按压和插销水平滑动 之间的传动关系。 由于按钮面按压到底后平行立柱， 因此便于用户控制按压限 度， 防止按压过度， 延长使用寿命。 该插销内端部与锁接孔、 内小孔匹配， 实 现微小间隙配合。 由于弹簧直接套装在插销上， 因此在插销位于第一位置吋， 弹簧直接施力于插销， 因此安全性好。 同吋， 在按压按纽吋不需要直接对弹簧 施力， 而是通过按纽拉动插销， 插销的水平滑动给弹簧施力， 使其受压变形， 因此弹簧不易受损， 使用寿命长， 可保证插销锁接定位效果。

[33] 实施例 1、 请査阅图 1、 图 2、 图 3、 图 4， 该滑动装置 10包括一滑动座 100、 一定 位套 200、 一插销 300、 一弹性体 400和一按钮 500。 [34] 该滑动座 100包括有： 一上下贯穿的滑动通孔 110; —包围滑动通孔 110的主套 体 150 ; —内外贯穿的水平的安装孔 120; —包围安装孔 120的、 固设在主套体 15 0之侧面的侧套体 160; 至少两个固设在主套体 150之外的、 用以连接剪刀状连杆 的连接部 140; 固设主套体 150之侧面、 侧套体 160之后的、 上下间隔的两基壁 17 0； 以及一固接两基壁 170之后的后壁 180。 其中： 该滑动通孔 110适配并滑动套 设在立柱之外， 以使滑动座 100和立柱之间构成上下滑动连接关系； 该滑动通孔 110与安装孔 120垂直相交并相通， 为了便于安装将该安装孔 120设计为内小外大 的阶梯孔， 它具有一外大孔和一内小孔， 内小孔内径与锁接孔内径相当； 该基 壁 170之端面都设置有一带有朝后开口的安装槽 130; 该侧套体 160、 基壁 170和 后壁 180之间形成一让位空间。
[35] 该定位套 200固定设置在安装孔 120的外大孔之内， 为了保证固定连接设计使该 定位套 200外径和安装孔 120的外大孔内径相当， 再配设一螺钉 220锁接安装孔和 定位套。 该定位套 200外端口向内延伸形成环体盖 210。
[36] 该插销 300具有一内端部、 一外端部和一介于内、 外端部之间的中间段。 该插 销 300的内端部与立柱的锁接孔、 安装孔 120的内小孔匹配， 而且， 为了便于插 接将该内端部端面设计成半球面或圆锥面。 为了连接在弹性体 400该中间段的中 部分向外凸设形成有凸起环 310。 该插销 300装设在安装孔 120内并在第一位置和 第二位置之间水平滑动， 在第一位置吋插销 300的内端部伸进滑动通孔 110并插 接进立柱的锁接孔以实现锁接， 如图 3所示， 在第二位置吋插销 300缩进安装孔 1 20以松释定位锁接， 如图 4所示。 该插销 300的外端部伸出定位套 200的环体盖 21 0之外， 该凸起环 310位于安装孔 120的外大孔、 定位套 200之内。
[37] 该弹性体 400为复位弹簧， 它套设在插销 300之外并顶抵插销 300的凸起环 310和 定位套 200的环体盖 210， 以产生有一使插销 300受顶抵并保持在第一位置的弹力
[38] 该按钮 500包括一中部和分别位于中部之前后的一拉接端 510、 一按钮部 520。
该按钮 500中部上下各向外凸设形成有凸柱 530， 该两凸柱 530上下对称设置。 该 两凸柱 530分别装设在两安装槽 130之内， 而且， 该安装槽 130的内径大于凸柱 53 0外径， 以使得凸柱 530能相对安装槽 130同吋滑动、 转动， 使得按钮 500和滑动 座 100之间构成同吋相对滑动和相对转动的活动连接关系， 以达到所需的活动轨 迹要求。 该拉接端 510设计成拨叉状， 拨叉套接插销 300的伸出于环体盖 210之外 的外端部， 另配设铆钉 511穿过插接端 510和外端部， 使得该插接端 510和插销 30 0的外端部之间构成枢接连接关系。 该按钮部 520凸设出按钮 500表面并位于后壁 180之前， 以使得按钮部 520能够位于让位空间之内， 而且， 该按钮部 520的按钮 面形成为一前低后高的倾斜面。
[39] 用户按压按钮部 520， 该按钮 500的拉接端 510水平向外滑动并带动插销 300的内 端部缩进安装孔 120以实现松释， 在此过程中， 该凸柱 530和安装槽 130之间的连 接关系构成同吋转动和滑动的活动连接关系， 以配合插接端的水平向外滑动轨 迹。
[40] 根据需要： 设计按钮部 520的按钮面倾斜角度和后壁 180的高度， 使得在按压到 底后， 按钮面刚好平行立柱， 按钮面刚好与后壁 180端面齐平， 因此具有如下优 点： 能够防止按压过度， 能够延长使用寿命。
[41] 根据需要： 设计安装槽 130的开口略小于凸柱 530的外径， 装配过程中， 由于开 口具有一定的弹性， 因此能够顺利将凸柱装配进安装槽； 装配后， 在该弹性作 用下能够防止凸柱脱离出安装槽， 因此具有如下优点： 能够方便装配， 能够加 强零部件之间的连接强度。
[42] 该安装槽为腰形槽， 该定位轴能同吋转动和滑动连接在安装槽之内， 以实现该 按钮和滑动座之间的能同吋相对转动和相对滑动的活动连接关系。
[43] 实施例 2， 请査阅图 5， 该安装槽 130开口朝上； 该拉接端 510设计成环套状， 它 套设在插销 300的伸出于环体盖 210之外的外端部， 另配设铆钉 511穿过插接端 51
0和外端部。
[44] 实施例 3， 请査阅图 6、 图 7， 本实施例与实施例 1不同之处在于： 其为一用作立 柱伸缩的固定， 基本结构与实施例 1相同， 其按钮 500与滑动座 100的安装方式与 实施例 1有所不同， 滑动座 100的上部开设有一能供按钮 500穿过的安装槽 190， 安装槽 190内设有一凸台 191， 而且， 该安装槽 190的间隙大于按钮 500的厚度， 以实现该按钮 500和滑动座 100之间的能同吋相对转动和相对滑动的活动连接关 系。 [45] 常态下， 在弹簧 400的直接作用下， 插销 300位于第一位置， 即插销 300通过滑 动通孔插入立柱锁接孔内形成定位； 需要收缩滑动吋， 按压按钮 500， 以安装槽 190内的凸台 191为支点， 按钮的拉接端向上拉起插销 300， 使其位于第二位置， 即插销 500脱离立柱的锁接孔； 由于按钮 500仅在其拉接端与插销 300铰接， 中部 支点处只有限位没有固定， 因此， 按钮本体相对于滑动座 100在凸台 191处同吋 转动和滑动的活动连接关系， 以配合插接端的水平向外滑动轨迹， 保证插销 300 直线运动。
工业实用性
[46] 本发明一种用在立柱的滑动装置， 它利用按钮按压实现单手操作， 利用插销水 平滑动实现微小间隙的牢固定位锁接， 利用按钮和滑动座之间的同吋相对转动 和相对滑动的活动连接关系实现用户按压和插销水平滑动之间的传动关系。 其 结构简单， 使用方便， 具有良好的工业实用性。
