Description

技术领域：
本发明涉及锁具技术领域，尤其是涉及一种应用于自行车上的马 蹄形锁。
背景技术：
见图 9所示： 传统的马蹄形锁 70固定结合于自行车的后车架或 前叉， 并具有可扳动的锁栅组 71， 当自行车停妥时， 可扳动马蹄形 锁 70—端的锁栅组 71穿过自行车的前轮或后轮， 并使锁栅组 71穿 设于马蹄形锁的另一端， 以形成一封闭的锁固空间 72， 并使马蹄形 锁 70上锁，让自行车的后轮部分可拘束于锁固空间 72内而无法移动。
当自行车已使用马蹄形锁 70上锁后， 仍然有自行车整台被人搬 运的风险存在， 而无法如同钢索头一样， 能够同时绑固于自行车及电 线杆或栏杆等固定处或与其它车辆进行锁合，故仍有改进加强的空间 存在。
发明内容：
为了解决传统的马蹄形锁的设计只能针对自行车自身上锁，而无 法连接锁合于固定处或连接锁合至其它车辆的问题，本发明的主要目 的在于提供一种具有双锁座的马蹄形锁，能够使马蹄形锁于上锁状态 时， 同时连接结合另一钢索头， 而使自身车辆形成上锁状态， 也 能够锁合于固定物或其它车辆， 从而具有更佳的防盗效果。
为实现上述目的， 本发明的具有双锁座的马蹄形锁包括有壳体、 锁栅组以及第一锁座， 其中， 壳体呈马蹄形， 可扳动的锁栅组位于壳 体中部， 用于锁住锁栅组的锁杆的第一锁座位于壳体一端， 壳体另一 端设有通过拉伸弹簧与锁栅组的锁杆相连的第二锁座，所述的第二锁 座具有锁座平台和卡制件， 其中， 锁座平台前端成型有凸出于壳体外 的插入部， 插入部上开设有供钢索头插入的插孔， 锁座平台后端成型 有与插孔连通的卡制槽， 枢接于卡制槽内的卡制件一端为结合部， 另 一端为与钢索头配合的扣部，结合部的顶面和底面分别结合有第一弹 簧和第二弹簧， 其中， 第一弹簧的一端与结合部顶面相连， 另一端抵 靠在锁座平台的抵靠壁上， 第二弹簧的一端与结合部底面相连， 另一 端构成与锁栅组的锁杆配合的压抵端。
作为上述技术方案的优选，所述的壳体由第一外壳和第二外壳铆 合固定构成， 其中， 第一外壳的两端分别形成有第一容置部、 第二容 置部， 第一锁座、 第二锁座分别设置在第一容置部、 第二容置部内。
作为上述技术方案的优选，所述的卡制件与钢索头配合的扣部呈 弯弧状。
作为上述技术方案的优选，所述的卡制件的结合部顶面开设有凹 槽， 第一弹簧下端卡设在凹槽内， 上端抵靠在锁座平台的抵靠壁上； 结合部底面成型有凸部， 第二弹簧上端与凸部相连， 下端形成与锁栅 组的锁杆配合的压抵端。
作为上述技术方案的优选， 所述第一弹簧的弹力小于第二弹簧。 本发明的有益效果在于：其在外壳上设有一个可卡制固定锁杆的 第一锁座， 以及可供钢索头进行锁固的第二锁座， 使得马蹄形锁能够 扳动锁栅组的锁杆卡制于第一锁座以形成锁固型态，同时可结合钢索 头连接并锁固其它的物件， 从而达到更佳的防盗效果。

具体实施方式：
以下所述仅为体现本发明原理的较佳实施例， 并不因此而限 定本发明的保护范围。
本发明的一种具有双锁座的马蹄形锁， 见图 1至图 3所示的 较佳实施例， 其包括一第一外壳 10、一第一锁座 20、一第二锁座 30、 一锁栅组 40及一第二外壳 50。
见图 1和图 2所示： 第一外壳 10为呈马蹄形的壳体， 并具有一 第一端 11及相对第一端设置的第二端 12， 并于第二端 12开设有一 开孔 14， 于第一外壳 10临近第一端 11的外侧开设有一呈现弧形的 滑槽 15， 于第一外壳 10内侧形成马蹄型凹陷状的一滑动槽 16， 并于 第一外壳 10内侧对应第一端 11的位置形成凹陷状的第一容置部 17， 于第一容置部 17的底部开设有一穿孔 171， 及于第一外壳 10内侧对 应于第二端 12的位置形成凹陷状的第二容置部 18， 第二容置部 18 连接于开孔 14。
如图 2所示，第一锁座 20对应设置于第一外壳 10的第一容置部 17内， 第一锁座 20具有一锁心 21， 锁心 21略为凸出穿孔 171并可 供一钥匙 （图中未示出） 插入进行转动解锁的动作， 由于第一锁座 20 的构造及工作原理为现有技术而非本发明的重点， 故不加以详细 说明。
图 2及图 3所示，第二锁座 30设置于第一外壳 10的第二容置部 18， 第二锁座 30包括有一锁座平台 31、 一卡制件 32、 一第一弹簧 33、 一第二弹簧 34。
锁座平台 31为内部呈中空状的块体， 并具有一顶面 311及一底 面 312， 于顶面 311具有一呈凸出状的插入部 313， 插入部 313具有 一插孔 3130， 锁座平台 31靠置于第一外壳 10的第二容置部 18， 并 以插入部 313凸出于第一外壳 10的外侧， 并于底面 312凹陷形成一 卡制槽 314， 卡制槽 314与插孔 3130相连通， 并于卡制槽 314—侧 延伸形成一抵靠壁 315， 卡制槽 314 内部具有一呈凸出状的枢转柱 316， 锁座平台 31临近抵靠壁 315的外周面凸设有一弯钩部 317， 弯 钩部 317朝向内侧弯曲。
如图 4和图 4所示， 卡制件 32为呈长条状的块体， 卡制件 32于 一端为一呈弯弧状的扣部 321， 于另一端具有一结合部 322， 于结合 部 322的侧面凹设有一凹槽 323， 并于结合部 322异于设有凹槽 323 的侧面凸出设有一凸部 324， 卡制件 32于扣部 324及结合部 322之 间贯穿设有一枢转孔 325， 卡制件 32以枢转孔 325枢设结合于枢转 柱 316， 并能够以枢转柱 316为转动中心做摆动动作。 卡制件 32以 扣部 321设置于卡制槽 314内， 卡制件 32的结合部 322凸伸于卡制 槽 314外， 并以凹槽 323面向抵靠壁 315。
第一弹簧 33以一端卡固设置于卡制件 32的凹槽 323内，并以另 一端抵靠抵靠壁 315。
第二弹簧 34以一端固设于卡制件 32的凸部 324， 另一端则形成 一压抵端。
如图 1和图 2所示，锁栅组 40可滑动地靠置于第一外壳 10的滑 动槽 16内，锁栅组 40包括有一锁杆 41、一拉伸弹簧 42及一拉柄 43， 锁杆 41 为对应第一外壳 10且呈圆弧状的圆柱体， 并具有一固定端 411及一抵靠端 412，锁杆 41中央位置的外周缘朝外凸伸设有一连接 板 413， 连接板 413穿出于第一外壳 10的滑槽 15， 临近连接板 413 的下方外周面凹设有一卡槽 414， 锁杆 41能够以卡槽 414卡固于第 一锁座 20， 锁杆 41的固定端 411结合有拉伸弹簧 42， 拉伸弹簧 42 以异于连接固定端 411 的一端结合第二锁座 30的弯钩部 317， 拉柄 43由第一外壳 10的外侧套设固定于连接板 413。
如图 2所示， 第二外壳 50外形对应于第一外壳 10， 且对应盖合 于第一锁座 20、 第二锁座 30及锁栅组 40后， 以铆钉分别穿设于第 一锁座 20及第二锁座 30且铆固结合于第一外壳 10， 使锁杆 41能够 于第一外壳 10及第二外壳 50之间扳动滑移。
本发明较佳的实施例如图 1、 图 4至图 8所示， 其中：
如图 5及图 7所示， 拉柄 43沿着滑槽 15朝下扳动， 能够使锁栅 组 40的锁杆 41抵靠至第二锁座 30， 此时锁杆 41将卡固于第一锁座 20处， 使锁栅组 40与第一外壳 10及第二外壳 50之间形成一环状的 锁固空间， 并使锁杆 41的抵靠端 412抵靠第二弹簧 34， 由于锁杆 41 抵紧第二弹簧 34的推力大于第一弹簧 33的弹力，因此可推动卡制件 32以枢转柱 316为中心， 使卡制件 32的扣部 321朝向卡制槽 314摆 动并呈凸出状。
如图 5和图 6所示， 可进一步于第二锁座 30的插入部 313连接 结合一钢索头 60， 钢索头 60具有一头部 61， 头部 61形成一环状的 凹沟 610， 当钢索头 60的头部 61穿入插入部 313的插孔 3130， 如图 7所示， 并插设于锁座平台 31的卡制槽 314内， 头部 61将会轻轻推 动卡制件 32并克服第二弹簧 34的弹力后， 扣部 321朝反方向摆动， 再将头部 61持续推动直到凹沟 610对应至扣部 321的位置时， 由于 卡制件 32受到第二弹簧 34的弹力弹回， 使卡制件 32以扣部 321卡 入头部 61的凹沟 610， 钢索头 60固定于第二锁座 30。
如图 1及图 4所示， 当欲将锁栅组 40或钢索头 60进行解锁时， 仅需以钥匙转动开启第一锁座 20的锁心 21进行解锁， 锁栅组 40解 除与第一锁座 20的卡制拘束状态后，锁栅组 40将回复至如图 1所示 的原定位， 而卡制件 32丧失了锁杆 41对第二弹簧 34压合抵紧的力 量， 而能够藉由第一弹簧 33自身的弹性弹回， 卡制件 32回复至原定 位， 解除了卡制件 32的扣部 321对钢索头 60的凹沟 610的拘束后， 可直接将钢索头 60取出， 完成整个解锁动作并回复至如图 1所示的 初始状态。
如图 8所示，其是将本发明固定于一自行车 B的后轮架及一后轮 B1 上方的位置， 除了能够卡制并锁合于后轮 B1 , 也可将钢索头 60 以交叉绑固的方式结合于一固定物 C如电线杆或栏杆之上后，再以钢 索头 60的头部 61锁固于本发明， 具有较佳的防盗效果， 相当地方便 实用。
需要说明的是， 以上所述仅是本发明的较佳实施例， 并非对本发 明作任何形式上的限制， 任何所属技术领域中具有通常知识者， 在不 脱离本发明所提供技术特征的范围内，利用本发明所揭示技术内容所 作出的局部变更或修饰的等效实施例，均仍属于本发明技术特征的范 围内。
