Description

防盗螺丝 技术领域
本发明涉及一种螺丝，尤其涉及一种防盗螺丝，其中该防盗螺丝能够防止其未经许可的拆卸。
背景技术
防盗螺丝一般又被称为防拆卸螺丝。很多户外产品，或者被放置在户外的产品，如机动车牌，室外护栏等，在未得到妥善管理时，会被偷盗而给使用者造成损失。实际上，对机动车牌、室外护栏等，仅需增大其被拆卸下来的难度，使小偷需要花费较长时间才能拆卸下来，即可使小偷知难而退和大大减小其被偷盗(未经许可的拆卸)的风险。
申请号为201220548114.6的中国实用新型专利教导了一种防拆卸安全(或防盗)螺丝，其包括一个转接头和一个螺接部，其中该转接头和该螺接部连接在一起，且两者之间的连接在高扭力下可被破坏，以使转接头脱离该螺接部和使被螺接在目标物体(被固定物体)上的螺接部难以被施力，从而使该螺接部难以被拆卸。但是，由于该防盗螺丝的该螺接部和该转接头之间的连接可在强扭力下被破坏。因此，如果该防盗螺丝的该螺接部和该转接头之间的连接强度过小，则该防盗螺丝的该螺接部和该转接头之间的连接可能在该防盗螺丝被螺接到目标物体过程中被破坏。如果该防盗螺丝的该螺接部和该转接头之间的连接强度过大，则该防盗螺丝的该螺接部和该转接头之间的连接可能在该防盗螺丝被螺接到目标物体后，需要很大的扭力才能被破坏，在此过程中，可能会导致被固定物体(目标物体)发生损坏。此外，由于需要破坏该防盗螺丝的该螺接部和该转接头之间的连接才能防止拆卸，则该防盗螺丝一般为一次性产品，无法被重复使用。最后，该防盗螺丝的该螺接部和该转接头之间的连接被破坏，不但会给小偷带来拆卸的困难，也会给使用者拆卸该防盗螺丝带来困难。
申请号为201320547389.2的中国实用新型专利教导了一种多用途防盗螺丝，其中该防盗螺丝的头部具有可以与扳手凹槽配合的凹孔。因此，该多用途防盗螺丝只是一种只有特殊扳手才能拆卸的螺丝，其并没有提供任何能够防盗的机构。
发明内容
本发明的主要目的在于其提供一种防盗螺丝，其中该防盗螺丝的受力端被隐藏地设置在一个保护套中，以防止其被未经许可驱动和自被固定物体上拆卸下来。
本发明的另一目的在于其提供一种防盗螺丝，其中当该防盗螺丝被螺接在目标物体上 时，该防盗螺丝的受力端可被隐藏在一个保护套中，且在未经许可情况下，该保护套被设置能够围绕该防盗螺丝的螺接部自由旋转，从而防止通过该防盗螺丝的该保护套将该防盗螺丝自该目标物体上拆卸下来。
本发明的另一目的在于其提供一种防盗螺丝，其中当该防盗螺丝被螺接在目标物体上时，该防盗螺丝的受力端可被隐藏在一个保护套中，且在得到许可情况下，该保护套被设置能够驱动该防盗螺丝的螺接部转动，从而该防盗螺丝的螺接在目标物体或将该防盗螺丝自目标物体上拆卸下来。
本发明的另一目的在于其提供一种防盗螺丝，其中该防盗螺丝仅当在其组合转盘被驱动和各个盘的缺口对齐和形成一个能够容纳驱动件的容纳槽时，该防盗螺丝的保护套才能驱动该受力端。换句话说，仅当该防盗螺丝处在解锁状态时，该防盗螺丝的保护套才能驱动该防盗螺丝的螺接部转动。而当该防盗螺丝处在锁合状态时，该防盗螺丝的保护套仅能围绕该防盗螺丝的螺接部自由空转。

具体实施方式
下述描述被揭露以使本领域技术人员可制造和使用本发明。下述描述中提供的较佳实施例仅作为对本领域技术人员显而易见的示例和修改，其并不构成对本发明范围的限制。下述描述中所定义的一般原理可不背离本发明精神和发明范围地应用于其它实施例、可选替代、修改、等同实施和应用。
参考附图之图1至图7B，依本发明较佳实施例的防盗螺丝被阐明，其中该包括一个螺接件10、一个外壳体20、一个盘单元30和一个驱动件40，其中该螺接件10包括一个螺接端11和一个自该螺接端11延伸的受力端12；该外壳体20形成一个容纳腔201和一个与该容纳腔201相连通的安装孔202；该盘单元30包括一组被设置在该外壳体20的该容纳腔201内的转盘31，且该盘单元30的每个转盘31具有一个第一缺口310；该驱动件40被可枢转地设置在该外壳体20的该容纳腔201内，其中该外壳体20通过该安装孔202 被可转动地设置在该螺接件10的该螺接端11，且该螺接件10的该受力端12的外径大于该外壳体20的该安装孔202的内径，其中该螺接件10的该受力端12具有一个第二缺口120，其中盘单元30的每个该转盘31被可转动地设置在该外壳体20的该容纳腔201内，从而使得每个该转盘31的该第一缺口310均可被调整与该螺接件10的该受力端12的该第二缺口120相对齐和形成一个容纳槽100，其中该驱动件40被设置能够通过该容纳槽100与该螺接件10的该受力端12相啮合，以使使用者能够通过转动该外壳体20来驱动该驱动件40转动和驱动该螺接件10的该受力端12转动，从而使该防盗螺丝被螺接在目标物体，或将该防盗螺丝自目标物体拆卸下来。可以理解的是，依本发明较佳实施例的防盗螺丝能够实现防止在未经许可情况下安装和拆卸和允许许可情况下的安装和拆卸。如附图之图4A，当本发明防盗螺丝的盘单元30的每个转盘31被调整以使所有转盘31的第一缺口310和该螺接件10的该受力端12的该第二缺口120相对齐时，该盘单元30和该螺接件10的该受力端12形成一个容纳该驱动件40的容纳槽100，从而使得该驱动件40通过该容纳槽100与该螺接件10的该受力端12相啮合，和使使用者能够通过旋转该外壳体20来驱动该驱动件40转动，进而驱动该螺接件10的该受力端12转动，从而实现该螺接件10的螺接和解螺接；如附图之图4B，当该防盗螺丝的盘单元30的任意一个转盘31被转动，以致其第一缺口310与该螺接件10的该受力端12的第二缺口120相错开时，该驱动件40即会被驱动离开该螺接件10的该受力端12和与该螺接件10的该受力端12相解啮合，此时，该驱动件40在该外壳体20的驱动下仅能围绕该螺接件10的该受力端12(和该盘单元30)转动，而不能驱动该螺接件10的该受力端12转动。此时，该外壳体20和该驱动件40均仅能围绕该盘单元30和该受力端12空转，而无法通过驱动驱动件40，从而驱动该螺接件10的该受力端12的方式将该螺接件10螺接在目标物体，和将该螺接件10自目标物体上拆卸下来。换句话说，该防盗螺丝允许使用者通过调整该防盗螺丝的该盘单元30的该转盘31的第一缺口310的位置来实现对该螺接件10的操作的许可和非许可，从而实现该防盗螺丝的防盗功能。
如附图之图1和图2，依本发明较佳实施例的该防盗螺丝的该外壳体20包括一个低端21、一个高端22和一个延伸在该低端21和该高端22之间的侧壁23，其中该外壳体20的该高端22形成一个与该外壳体20的该容纳腔201相连通的操作孔203，其中该操作孔203的内径小于该盘单元30的该转盘31的外径，从而使得该盘单元30的每个转盘31均被保持在该外壳体20的该容纳腔201之内。优选地，该盘单元30的每个转盘31均被可转动地设置在该螺接件10的该受力端12和该外壳体20的该高端22之间。
如附图之图2至图3B，依本发明较佳实施例的该防盗螺丝的该盘单元30的该转盘组31包括一个主动盘311，其中该主动盘311具有至少一个第一缺口310，其中该第一缺口310形成在该主动盘311的外周边缘，以允许该驱动件40进入该第一缺口310，从而使得当该盘单元30的每个转盘31(该主动盘311)的该第一缺口310均与该螺接件10的该受力端12的该第二缺口120相对齐时，该盘单元30的该转盘31的该第一缺口310和该受力端12的该第二缺口120形成一个容纳该驱动件40的容纳槽100，和使该驱动件40通过该容纳槽100与该受力端12相啮合，从而使得当该驱动件40被驱动转动时，该螺接件10的该受力端12被驱动转动和使该螺接件10被螺接在目标物体或与该目标物体相解螺接。
如附图之图8A和图8B所示，依本发明较佳实施例的该防盗螺丝的该盘单元30的该主动盘311包括一个驱动本体3111，其中该第一缺口310自上而下形成穿过该驱动本体3111，从而使得该驱动本体3111形成两个滑动侧3112，其中当该驱动件40落入该主动盘311的该第一缺口310后，转动该主动盘311，则该驱动件40将会被驱动沿该驱动本体3111的相应滑动侧3112滑动和脱离该第一缺口310。换句话说，当该主动盘3111被转动时，该主动盘3111的该滑动侧3112将驱动该驱动件40离开该容纳槽100和使该驱动件40与该螺接件10的该受力端12相解啮合。此时，当该驱动件40被驱动转动时，该驱动件40将围绕该防盗螺丝的该盘单元30自由转动。同时，由于该防盗螺丝的该外壳体20的保护作用，该驱动件40无法被外力强制性地与该防盗螺丝的该受力端12相啮合在一起，从而使得该防盗螺丝难以在未经许可情况下被螺接或解螺接。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该盘单元30的该转盘组31进一步包括一组从动盘312，其中该从动盘312被依次设置在该主动盘311和该螺接件10的该受力端12之间，其中该从动盘312具有至少一个第一缺口310，其中该第一缺口310形成在该从动盘312的外周边缘，以允许该驱动件40进入该第一缺口310，从而使得当该盘单元30的每个转盘31(该主动盘311和该从动盘312)的该第一缺口310均与该螺接件10的该受力端12的该第二缺口120相对齐时，该盘单元30的该转盘31的该第一缺口310和该受力端12的该第二缺口120形成一个容纳该驱动件40的容纳槽100，和使该驱动件40通过该容纳槽100与该受力端12相啮合，从而使得当该驱动件40被驱动转动时，该螺接件10的该受力端12被驱动转动和使该螺接件10被螺接在目标物体或与该目标物体相解螺接。可以理解的是，该盘单元30的该转盘组31的该主动盘311被设置能够驱动与其相邻的从动盘312转动，和该从动盘312被设置能够驱动与其相邻的 另一个从动盘312转动。
如附图之图8A和图8B所示，依本发明较佳实施例的该防盗螺丝的该盘单元30的该从动盘312包括一个从动本体3121，其中该第一缺口310自上而下形成穿过该从动本体3121，从而使得该从动本体3121形成两个滑动侧3122，其中当该驱动件40落入该从动盘312的该第一缺口310后，转动任一从动盘312，则该驱动件40将会被驱动沿该从动盘312的该从动本体3121的相应滑动侧3122滑动和脱离该第一缺口310。换句话说，当该从动盘3121被转动时，该从动盘3121的该滑动侧3122将驱动该驱动件40离开该容纳槽100和使该驱动件40与该螺接件10的该受力端12相解啮合。此时，当该驱动件40被驱动转动时，该驱动件40将围绕该防盗螺丝的该盘单元30自由转动。同时，由于该防盗螺丝的该外壳体20的保护作用，该驱动件40无法被外力强制性地与该防盗螺丝的该受力端12相啮合在一起，从而使得该防盗螺丝难以在未经许可情况下被螺接或解螺接。
如附图之图8A和图8B所示，依本发明较佳实施例的该防盗螺丝的该盘单元30的该主动盘311的该驱动本体3111形成一个朝向该外壳体20的该操作孔203的操作侧3113和一个朝向该从动盘312的第一驱动侧3114，其中该主动盘311的该操作侧3113允许使用者通过该操作孔203操作该主动盘311转动，该主动盘311的进一步包括至少一个自该驱动本体3111的该第一驱动侧3114延伸的第一驱动销3115，其中每个该从动盘312的该从动本体3121形成一个朝向该主动盘311的从动侧3123和一个朝向该螺接件10的该受力端12的该第二驱动侧3124，其中该从动盘312进一步包括至少一个自该驱动本体3111的该从动侧3123延伸的从动销3125和一个自该从动盘312的该第二驱动侧3124延伸的第二驱动销3126。可以理解的是，该主动盘311被设置能够通过该第一驱动销3115来驱动与该主动盘311相邻的该从动盘312的该从动销3115，从而驱动该从动盘312转动。同样地，被该主动盘311驱动的该从动盘312通过其第二驱动销3116来驱动下一个从动盘312的该从动销3115来驱动下一个从动盘312的转动。以此顺序，使用者可通过转动该主动盘311的方式来驱动该从动盘312的转动和调节该主动盘311的该第一缺口310、该从动盘312的该第一缺口310和该螺接件10的该受力端12的该第二缺口120相对齐和形成该容纳槽100。
值得注意的是，该主动盘311和与该主动盘311相邻的该从动盘312之间的距离为L1，其中该主动盘31的该第一驱动销3115的高度为H1，紧接该主动盘311的该从动盘312的该从动销3125的高度为H2，其中该距离L1小于高度H1和高度H2的总和，从而使得当该主动盘311旋转时，该第一驱动销3115可与从动销3125相遇并推动该从动销 3125，从而推动该从动盘312转动。相似地，两个相邻从动盘312之间的距离为L2，其中两个相邻从动盘312中的上从动盘312的第二驱动销3126的高度为H2，下从动盘312的该从动销3125的高度为H3，其中该距离L2小于高度H2和高度H3的总和，从而使得当上从动盘312旋转时，上从动盘312的第二驱动销3126可与下从动盘312的从动销3125相遇，从而使该上从动盘312能够驱动该下从动盘312转动。因此，该防盗螺丝的该主动盘311的该第一驱动销3115和该从动盘312的该从动销3125和该第二驱动销3126分别被设置在该主动盘311的该驱动本体3111和该从动盘312的该从动本体3121的适当位置，以使该主动盘311与其相邻的该从动盘312之间、两个相邻从动盘312之间能够通过该第一驱动销3115、该从动销3125和该第二驱动销3126形成驱动和被驱动关系和使前者能够驱动后者转动。
如附图之图2至图3B，该盘单元30进一步包括一个位于该盘单元30的该从动盘312与该螺接件10的该受力端12之间的弹簧313以将该主动盘311和该从动盘312保持在适当位置。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝进一步包括一个弹性元件50，其中该弹性元件50被设置在该驱动件40与该外壳体20之间，以在该驱动件40转动至与该盘单元30形成的容纳槽100对齐时，推动该驱动件40落入该容纳槽100，从而确保在该盘单元30形成该容纳槽100时，该驱动件40与该螺接件10的该受力端12相啮合在一起。如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该驱动件40包括一个枢转端41和一个自该枢转端41延伸的驱动端42，其中该驱动件40的该枢转端41被可枢转地设置在该外壳体20的该低端21和该高端22之间，该驱动端42被设置能够容纳在该盘单元30和该螺接件10的该受力端12形成的该容纳槽100，从而使该驱动件40的该驱动端42与该螺接件10的该受力端12相啮合在一起。优选地，该驱动件40的该枢转端41被设置在该外壳体20的该低端21和该高端22，以在该外壳体20被驱动转动时，该外壳体20能够带动该驱动件40转动。可以理解的是，当该盘单元30和该螺接件40形成该容纳槽100时，该驱动件40能够在该外壳体20的带动下，沿该盘单元30的该转盘组31的外周缘移动，从而使该驱动件40的该驱动端42与该容纳槽100相对齐时，落入该容纳槽100，和使该驱动件40的该驱动端42与该螺接件10的该受力端12相啮合在一起，此时，当使用者驱动该外壳体20转动时，该外壳体20将带动该驱动件40转动，该驱动件40驱动该螺接件10的该受力端12转动，从而将该螺接件40螺接在目标物体，或将该螺接件40自目标物体拆卸下来；当该盘单元30的任意一个转盘 31(该主动盘311或该从动盘312)被进一步转动和该转盘31的该第一缺口310与该盘单元30的其它转盘31的第一缺口310相错开时，被转动的该转盘31(该主动盘311或该从动盘312)推动该驱动件40的该驱动端42离开该容纳槽100，和该盘单元30和该螺接件10的该受力端12形成的该容纳槽100被破坏，该驱动件40在该外壳体20的驱动下，沿该盘单元30的该转盘31的该外周缘自由移动。换句话说，当该盘单元30的任意一个转盘31(该主动盘311或该从动盘312)被进一步转动和该转盘31的该第一缺口310与该盘单元30的其它转盘31的第一缺口310相错开时，该驱动件40均将无法再与该螺接件10的该受力端12相啮合在一起和驱动该螺接件10的该受力端12转动。此时，该驱动件40仅能在该外壳体20的带动下，围绕该盘单元30的该转盘组31和该螺接件10的该受力端12自由转动。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该驱动件40被可枢转地设置在该外壳体20的该低端21和该高端22之间，以使该驱动件40在受到该弹性元件50的推力时，该驱动件40能够枢转转动，从而使得当该盘单元30的该转盘组31和该螺接件10的该受力端12形成该容纳槽100时，该驱动件40能够落入该容纳槽100和与该螺接件10的该受力端12相啮合在一起。优选地，该弹性元件50自该驱动件40延伸至该外壳体20。更优选地，该弹性元件50为涡卷弹片，其中该涡卷弹片的一端被设置在该驱动件40，另一端被设置在该外壳体20的该低端21。最优选地，该涡卷弹片的一端被设置在该驱动件40的该驱动端42，另一端被固定在该外壳体20的该低端21和该侧壁23，如附图之图3A和图3B所示。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该外壳体20的该侧壁23包括一个外侧231和一个内侧232，其中该侧壁23的该外侧231和该内侧232形成一个位于两者之间的窄槽230，其中该弹性元件50为适于安装在该窄槽230，以保持该涡卷弹片的形状和防止其发生变形，影响该涡卷弹片对该驱动件40施加推力。
如附图之图7A至图7B所示，依本发明较佳实施例的该防盗螺丝的该驱动件40的该驱动端42包括一个适于被容纳在该转盘31的该第一缺口310的低端部421和一个自该低端部421向上延伸的高端部422，其中该高端部422适于与该螺接件10的该受力端12相啮合在一起，其中该盘单元30的该转盘31的该滑动侧3112形成两个相对的驱离斜面3101，其中当该盘单元30的该转盘31被转动时，该盘单元30的该转盘31的该驱动端42的该驱离斜面3101能够抵压在该驱动件40的该驱动端42的该高端部422并推动该驱动件40的该驱动端42离开该盘单元30的该转盘31的该第一缺口310，从而使该驱动端 42的该高端部422与该螺接件10的该受力端12相解啮合。换句话说，该驱动件40的该驱动端42的该驱离斜面3101被设置能够推动该驱动件40枢转，从而使该驱动件40的该驱动端42与该螺接件10的该受力端12不再相啮合在一起。同时，由于该盘单元30的该转盘31的转动和该转盘31的该第一缺口310与其它转盘31的第一缺口310相互错开，导致该盘单元30的该转盘组31形成的该容纳槽100被破坏，和使该驱动件40仅能围绕该盘单元30的该转盘组31空转，而不再能够带动该螺接件10转动。此时，使用者即使施力驱动该外壳体20转动，该外壳体20也无法驱动该驱动件40转动以驱动该螺接件10转动。如附图之图7A至图8B所示，依本发明较佳实施例的该防盗螺丝的该驱动件40的该驱动端42的该高端部422被设置能够通过该螺接件10的该受力端12的该第二缺口120与该受力端12相啮合在一起，以防止在该驱动件40驱动该螺接件10转动时，该高端部422自该受力端12滑脱。换句话说，该驱动件40的该驱动端42的该高端部422的末端形成一个啮合部，该啮合部被设置能够与该螺接件10的该受力端12的该第二缺口120相匹配，以确保在该螺接件10被驱动转动期间，除非该盘单元30的该转盘31驱动该该驱动端42的该高端部422与该受力端12相解啮合，否则，该驱动端42的该高端部422不会自该受力端12滑脱。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝进一步包括一个保持单元60，其中该保持单元60包括一个被可转动地设置在该盘单元30与该螺接件10的该受力端12之间的第一保持件61，其中该第一保持件61被延伸至该外壳体20的该侧壁23和被设置与该外壳体20保持同步转动。可以理解的是，该外壳体20可被用于将该盘单元30的该转盘组31稳定地保持在适当位置。优选地，该弹性元件50被设置在该第一保持件61，以确保该弹性元件50能够与该外壳体20同步转动和保持该弹性元件50被保持在适当位置。更优选地，该第一保持件61被设置在该外壳体20的该侧壁23，且该外壳体20能够驱动该第一保持件61与该外壳体20同步转动。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该第一保持件61形成一个第三缺口610，且该第三缺口610被设置正对该驱动件40的该驱动端42。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该保持单元60进一步包括一个被可转动地设置在该盘单元30的该主动盘311上方的第二保持件62，其中该第二保持件62被设置在该外壳体20的该侧壁23，且该第二保持件62与该盘单元30的该主动盘311被相互隔开，以使该第二保持件62能够保持与该外壳体20同步转动，且该第二保持件62和该盘单元30的该主动盘311不会相互影响彼此转动。换句话说，该第 二保持件62的转动不会影响到该主动盘311，且该主动盘311的转动也不会影响到该第二保持件62。优选地，该第二保持件62与该外壳体20的该侧壁23一体成型。
可以理解的是，依本发明较佳实施例的该防盗螺丝的该保持单元60的该第一保持件61和该第二保持件62能够保持该外壳体20与该盘单元30的相对位置和确保该外壳体20能够稳定地相对该盘单元30转动。同时，由于该盘单元30的该主动盘311和该从动盘312均被该第二保持件62遮蔽，因此，该外壳体20和该保持单元60还进一步对该盘单元30具有保护作用。优选地，该第二保持件62与该外壳体20的该侧壁23一体成型，且该第二保持件62为圆盘形，从而使得该盘单元30的该转盘31均被该第二保持件62遮蔽在该外壳体20的该容纳腔201。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝进一步包括一个自该螺接件10的该受力端12向上延伸的枢转轴70，其中该盘单元30的该转盘31和该第一保持件61均被可转动地设置在该枢转轴70。可以理解的是，该盘单元30的该转盘31和该第一保持件61均具有枢转孔，以使其能够被可转动地套设在该枢转轴70。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝进一步包括一个被设置在该第一保持件61与该盘单元30的该转盘组31之间的压紧弹簧80，该压紧弹簧80可被用于将该盘单元30的该转盘组31的该主动盘311和该从动盘312稳定地保持在适当位置，从而确保该转盘31能够稳定地围绕该枢转轴70转动。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝进一步包括一组被分别设置在该盘单元30的两个相邻转盘31之间的垫片90，以避免两个相邻转盘31之间发生磨损和提高该防盗螺丝的该盘单元30的使用寿命。
如附图之图2至图3B所示，依本发明较佳实施例的该防盗螺丝的该盘单元30进一步包括一个被固定设置在该盘单元30的该主动盘311的操作块32，其中该操作块32被可转动地设置在该枢转轴70，且该操作块32被隐藏地设置在该外壳体20形成的该操作孔203，以允许使用者用过操作该操作块32实现驱动该盘单元30的该主动盘311和该从动盘312的转动，从而使该盘单元30的该转盘组31的该第一缺口310分别与该螺接件10的该受力端12的该第二缺口120相对齐和形成该容纳槽100，或使该盘单元30的该转盘组31驱动该驱动件40的该驱动端42离开该转盘组31的该第一缺口310和该受力端12的该第二缺口120。
