具体实施方式
请参照图1及图2，其中图1绘示依照本发明一实施例的快拆装置100的示意图，图2绘示依照图1实施例的快拆装置100的分解图。如图1及图2所示，快拆装置100包含壳体110、第一掣动结构120、第二掣动结构130、第一弹性元件140及第二弹性元件150。壳体110具有中心轴X、穿孔111及二个开口112，其中中心轴X穿过穿孔111，且开口112位于壳体110的二侧。第一掣动结构120设置于壳体110中且包含第一卡合部121及第一抵顶部122。第一抵顶部122连接于第一卡合部121，且对应于壳体110的二个开口112中之一者。第二掣动结构130设置于壳体110中且包含第二卡合部131及第二抵顶部132。第二卡合部131与第一卡合部121形成卡合空间(图未标号)，其中卡合空间对应于穿孔111。第二抵顶部132连接于第二卡合部131，且对应于壳体110的二个开口112中之另一者。第一弹性元件140可压缩地连接于第一卡合部121与第二抵顶部132之间，且第二弹性元件150可压缩地连接于第二卡合部131与第一抵顶部122之间。
请配合参照图3至图6，其中图3绘示依照图1实施例中第一掣动结构120、第二掣动结构130、第一弹性元件140及第二弹性元件150于一作动状态的仰视图，图4绘示依照图1实施例中第一掣动结构120、第二掣动结构130、第一弹性元件140及第二弹性元件150于另一作动状态的仰视图，图5绘示依照图3作动状态的立体示意图，图6绘示依照图4作动状态的立体示意图。如图1、图3及图5所示，由于第一掣动结构120与第二掣动结构130设置于壳体110时，第一抵顶部122与第二抵顶部132分别对应开口112外露，故当使用者由壳体110的开口112推抵第一抵顶部122与第二抵顶部132时，第一弹性元件140与第二弹性元件150分别压缩并使第一卡合部121与第二卡合部131的相对位置改变，借以扩大卡合空间供目标物件(图未绘示)通过穿孔111穿过卡合空间。目标物件可以是轴件，但本发明不以此为限。如图4及图6所示，当使用者释放第一抵顶部122与第二抵顶部132时，通过第一弹性元件140与第二弹性元件150的弹性回复力，将第一卡合部121与第二卡合部131恢复至未推抵时的相对位置，借以缩小卡合空间，使得目标物件卡合于第一卡合部121与第二卡合部131之间。借此，快拆装置100可稳定且快速地卡合目标物件或从目标物件上拆卸。
具体而言，第一卡合部121与第二卡合部131分别具有开孔121a、131a，第一卡合部121的开孔121a与第二卡合部131的开孔131a相互对应而形成卡合空间，但本发明不以此为限。详细来说，当使用者将第一抵顶部122与第二抵顶部132同时朝向快拆装置100的中心轴X推抵时，第一卡合部 121的开孔121a与第二卡合部131的开孔131a互相对应，使得卡合空间大于目标物件，目标物件可位移地穿过快拆装置100；当使用者释放对第一抵顶部122与第二抵顶部132的推抵时，第一卡合部121的开孔121a与第二卡合部131的开孔131a部分交错，使得目标物件卡合于第一卡合部121的开孔121a内壁与第二卡合部131的开孔131a内壁之间。
如图2所示，壳体110可包含二个壳板110a、110b，壳板110a、110b可以螺丝锁固于壳体110，但本发明不以此为限。借此，可避免第一掣动结构120与第二掣动结构130松脱。
图2实施例中，第一卡合部121及第一抵顶部122与第二卡合部131及第二抵顶部132分别一体成型形成第一掣动结构120及第二掣动结构130，但本发明不以此为限。借此，可强化第一掣动结构120与第二掣动结构130的结构强度。
请配合参照图7，其中图7绘示依照图1实施例的快拆装置100的剖面图。如图2及图7所示，第一卡合部121与第二卡合部131可为斜向结构，且彼此对应。当目标物件卡合于第一卡合部121与第二卡合部131之间时，斜向结构可使第一卡合部121与第二卡合部131互相抵顶，借以降低目标物件卡合时的应力，减少目标物件的磨损。
在图7实施例中，壳体110可包含二个止挡结构113。二个止挡结构113分别位于第一抵顶部122往穿孔111之处及第二抵顶部132往穿孔111之处。以第一抵顶部122为例，当第一抵顶部122受推抵朝向中心轴X位移并压缩第二弹性元件150时，止挡结构113可限制第一抵顶部122朝向中心轴X位移的距离，进而防止第一抵顶部122过度压缩第二弹性元件150，降低第二弹性元件150弹性疲劳的可能。
请参照图8，其绘示依照本发明另一实施例的快拆装置200的剖面图。如图8所示，快拆装置200包含壳体210、第一掣动结构220、第二掣动结构230、第一弹性元件240及第二弹性元件250。壳体210具有穿孔(图未标号)及二个开口(图未标号)，其中开口位于壳体210的二侧。第一掣动结构220设置于壳体210中且包含第一卡合部221及第一抵顶部222。第一抵顶部222连接于第一卡合部221，且对应于壳体210的二个开口中之一者。第二掣动结构230设置于壳体210中且包含第二卡合部231及第二抵顶部232。第二卡合部231与第一卡合部221形成卡合空间(图未标号)，其中卡合空间对应于穿孔。第二抵顶部232连接于第二卡合部231，且对应于壳体210的二个开口中之另一者。第一弹性元件240可压缩地连接于第一卡合部221与第二抵顶部232之间，且第二弹性元件250可压缩地连接于第二卡合部231与第一抵顶部222之间。
再者，第一卡合部221及第一抵顶部222与第二卡合部231及第二抵顶部232分别组装成第一掣动结构220与第二掣动结构230，但本发明不以此为限。借此，可降低掣动结构制作的难度。
图8实施例中，第一卡合部221与第二卡合部231的结构与图1实施例中第一卡合部121与第二卡合部131的结构相同，在此不另赘述。
请参照图9及图10，其中图9绘示依照又一实施例的快拆装置中第一掣动结构320、第二掣动结构330、第一弹性元件340及第二弹性元件350于一作动状态的剖面示意图，图10绘示依照图9实施例中第一掣动结构320、第二掣动结构330、第一弹性元件340及第二弹性元件350于另一作动状态的剖面示意图。如图9所示，快拆装置(图未绘示)包含壳体(图未绘示)、第一掣动结构320、第二掣动结构330、第一弹性元件340及第二弹性元件350。必须说明的是，图9实施例中，快拆装置与图8实施例中的快拆装置200的差异在于第一掣动结构320及第二掣动结构330的结构，其余元件的配置与结构皆相同，在此不另赘述。
图9实施例中，第一掣动结构320包含第一卡合部321及第一抵顶部322。第二掣动结构330包含第二卡合部331及第二抵顶部332。第二卡合部331与第一卡合部321形成卡合空间(图未标号)，其中卡合空间对应于壳体的穿孔(图未绘示)。具体而言，第一卡合部321及第一抵顶部322与第二卡合部331及第二抵顶部332分别一体成型形成第一掣动结构320及第二掣动结构330，但本发明不以此为限。借此，可强化第一掣动结构320与第二掣动结构330的结构强度并降低制作成本。
再者，如图9所示，当使用者推抵第一抵顶部322与第二抵顶部332时，第一弹性元件340与第二弹性元件350分别压缩并增加第一卡合部321与第二卡合部331的相对距离，借以扩大卡合空间供目标物件(图未绘示)穿过卡合空间。如图10所示，当使用者释放对第一抵顶部322与第二抵顶部332的推抵时，通过第一弹性元件340与第二弹性元件350的弹性回复力，将第一卡合部321与第二卡合部331恢复至未推抵时的相对位置；换句话说，通过缩短第一卡合部321与第二卡合部331的相对距离，借以缩小卡合空间，使得目标物件卡合于第一卡合部321与第二卡合部331之间。借此，快拆装置可在简单的结构下，稳定且快速地卡合目标物件或从目标物件上拆卸。
请参照图11及图12，其中图11绘示依照本发明一实施例的负重器10的立体示意图，图12绘示依照图11实施例的负重器10的分解图。如图11及图12所示，负重器10包含一轴件11、至少一个快拆装置400、至少一个定位元件12及多个配重元件13。快拆装置400可分离地设置于轴件11。定位元件12设置于轴件11，且与快拆装置400对应。配重元件13可分离 地设置于轴件11，且位于定位元件12与快拆装置400之间。具体而言，快拆装置400可以是图1、图8或图9实施例的快拆装置，但本发明不以此为限。快拆装置400可由轴件11上拆卸，借以调整配重元件13的数量，且通过快拆装置400与定位元件12的配置，可防止配重元件13从轴件11上脱落。借此，可快速调整负重器10的负重重量，并稳定地将配重元件13定位于轴件11。
请配合参照图13，其绘示依照图11实施例中第一掣动结构420、第二掣动结构430、第一弹性元件440、第二弹性元件450及轴件11的组合示意图。如图12及图13所示，快拆装置400包含壳体(图未标号)、第一掣动结构420、第二掣动结构430、第一弹性元件440及第二弹性元件450。壳体具有穿孔(图未标号)及二个开口(图未标号)，其中二个开口位于壳体的二侧，且轴件11穿过穿孔。第一掣动结构420包含第一卡合部421及第一抵顶部422。第二掣动结构430包含第二卡合部431及第二抵顶部432。图13实施例中，第一掣动结构420、第二掣动结构430、第一弹性元件440及第二弹性元件450与图1实施例的第一掣动结构120、第二掣动结构130、第一弹性元件140及第二弹性元件150的结构与配置相同，在此不另赘述。再者，轴件11可包含多个沟槽11a。快拆装置400的第一卡合部421与第二卡合部431可位移地卡合于沟槽11a之一者。当使用者推抵第一抵顶部422及第二抵顶部432时，使得快拆装置400分离于轴件11并可在轴件11上位移，借以调整位置至沟槽11a之一者上；当使用者不再推抵第一抵顶部422及第二抵顶部432时，使得第一卡合部421与第二卡合部431卡合于沟槽11a之一者。通过沟槽11a的配置，可防止快拆装置400因非预期的外力脱落于轴件11。借此，可增加快拆装置400卡合轴件11的稳定度。
具体而言，图11实施例中，至少一个快拆装置400的数量为二，至少一个定位元件12为二，各快拆装置400与各定位元件12之间分别设置四配重元件13，且各配重元件13的尺寸及重量可相同或不同，本发明不以此为限。再者，轴件11位于二个定位元件12之间的区域可包覆TPR(Thermoplastic Rubber)层，TPR层由热塑性材料制成，可在使用者握持时提供防滑的效果。详细来说，各配重元件13可包含防护层，其由聚氨酯(Polyurethane,PU)材料制成，可缓冲配重元件13撞击地面的冲击力，但本发明不以此为限。
请参照图14及图15，其中图14绘示依照本发明另一实施例的负重器的部分剖面图，图15绘示依照图14实施例的负重器的另一部分剖面图。如图14及图15所示，负重器(图未标号)包含轴件21、至少一个快拆装置500、至少一个定位元件22及多个配重元件23。轴件可包含多个沟槽21a。图14实施例中，图14实施例的负重器的元件结构及配置与第图11实施例 的负重器的元件结构及配置相同，在此不另赘述。必须说明的是，图14实施例的快拆装置500的元件结构及配置与图8实施例的快拆装置200的元件结构及配置相同，在此不另赘述。
如图14所示，当使用者未推抵快拆装置500的第一抵顶部522与第二抵顶部532时，快拆装置500的第一卡合部521与第二卡合部531卡合于沟槽21a之一者。如图15所示，当使用者推抵快拆装置500的第一抵顶部522与第二抵顶部532时，可将快拆装置500由轴件21上卸除，并且调整配重元件23的数量，而后将快拆装置500位移至轴件21上，并调整快拆装置500的位置卡合于沟槽21a之另一者，借以快拆装置500与定位元件22稳定定位配重元件23。
请参照图16及图17，其中图16绘示依照本发明又一实施例的负重器30的立体示意图，图17绘示依照图16实施例的负重器30的分解图。如图16及图17所示，负重器30包含轴件31、至少一个快拆装置600、至少一个定位元件32及多个配重元件33。快拆装置600可分离地设置于轴件31。定位元件32设置于轴件31，且与快拆装置600对应。配重元件33可分离地设置于轴件31，且位于定位元件32与快拆装置600之间。具体而言，快拆装置600可以是图1、图8或图9实施例的快拆装置，但本发明不以此为限。
图16实施例中，轴件31可包含多个沟槽31a，且快拆装置600的第一卡合部(图未绘示)与第二卡合部(图未绘示)可位移地卡合于沟槽31a之一者。轴件31可更包含至少一个连接杆31b及至少一个连接元件31c，且至少一个连接元件31c连接于各至少一个连接杆31b之间。根据使用者需求，轴件31可通过连接元件31c连接连接杆31b组成不同的长度。具体而言，至少一个连接杆31b的数量为二，至少一个连接元件31c的数量为一。借此，可提供不同长度的轴件31。
请参照图18至图20，其中图18绘示依照本发明再一实施例的负重器40的立体示意图，图19绘示依照图18实施例的负重器40的分解图，图20绘示依照图18实施例的负重器40的部分剖面图。如图18至图19所示，负重器40包含底座41、上盖42、握杆43、轴件44、快拆装置700及多个配重元件45。上盖42可分离地盖设于底座41，且与底座41形成容置空间(图未标号)。握杆43穿设于上盖42，且连接于底座41。轴件44固定于底座41，且位于容置空间中。快拆装置700位于容置空间，并可分离地设置于轴件44。配重元件45位于容置空间，并可分离地设置于轴件44，且位于底座41与快拆装置700之间。具体而言，快拆装置700可以是图1、图8或图9实施例的快拆装置，但本发明不以此为限。轴件44穿过快拆装置700的壳体(图未标号)之穿孔(图未标号)。快拆装置700可由轴件44上拆 卸，借以调整配重元件45的数量。借此，可快速调整负重器10的负重重量。
如图18所示，上盖42可包含观测口42a。借此，有利于观测容置空间中配重元件45的数量。
如图19所示，轴件44可包含多个沟槽44a。快拆装置700的第一卡合部(图未标号)与第二卡合部(图未标号)卡合于沟槽44a之一者。
具体而言，底座41可包含一离合钮41a。离合钮41a设置于底座41的一侧面，并具有楔形齿41b，其中该楔形齿41b勾合于上盖42。借此，使用者可推压离合钮41a，使得楔形齿41b与上盖42脱勾，进而使底座41与上盖42分离，方便使用者调整容置空间中的快拆装置700的位置及配重元件45的数量。
再者，底座41可更包含防撞垫46，其以弹性材料组成。借此，可防止负重器40意外撞击地面，造成负重器40或地面损坏。
综上所述，本发明所提供的快拆装置及负重器具有下列优点：其一，通过掣动结构与弹性元件的配置，可方便使用者从目标物件中快速拆卸快拆装置或移动快拆装置于目标物件上的位置。其二，通过快拆装置，可根据使用者的需求调整负重器的配重。
以上所述，仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
