具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，以下结合实施例及附图对本发明的快速更换安装的撞针机构及射钉枪作具体阐述。
<实施例一>
图1是本发明实施例中的射钉枪的立体图。
图2是本发明实施例中射钉枪的结构分解图1。
图3是本发明实施例中射钉枪的结构分解图2。
如图1-3所示，本实施例的射钉枪10包括快速更换安装的撞针机构12。射钉枪10还包括图中未示出的设置在外壳20内的电机、电池等常规内部部件，具体为现有技术不多赘述。
快速更换安装的撞针机构12用于对安装在射钉枪10内的撞针40进行快速更换及安装。快速更换安装的撞针机构12包括外壳20、设置在外壳20内的撞针驱动组件30以及撞针40。本实施例中，撞针40在撞针驱动组件30的驱动下沿预定的往复运动方向进行运动，图2中箭头D1所指示的方向为射钉方向，箭头D2所指示的方向为蓄能方向，往复运动方向包括上述的射钉方向以及蓄能方向。
外壳20包括主体机壳21以及撞针挡板22。
主体机壳21用于容置上述的撞针驱动组件30、撞针40、电机、电池等内部 部件，并对上述的内部部件起到保护作用。主体机壳21包括左外机壳211、右外机壳212以及多个外壳紧固件214。此外，本实施例中，“左”、“右”、“上”、“下”各个方向是以操作者持枪射钉时面对方向为基准的左侧、右侧、上方、下方。
左外机壳211以及右外机壳212能够相互配合安装到一起形成一体的主体机壳21，并能通过多个外壳紧固件214实现紧固。本实施例中，外壳紧固件214为与左外机壳211以及右外机壳212上的机壳安装孔相匹配的镙钉。
左外机壳211的顶部具有左壳缺口2111，右外机壳212具有与左壳缺口2111相匹配的右壳缺口2121，当左外机壳211与右外机壳212相互配合安装到一起时，左壳缺口2111以及右壳缺口2121拼合成更换开口213，也即主体机壳21具有一个更换开口213，用于更换撞针40。
更换开口213大致为矩形，其长度大于撞针40的长度，且其宽度大于撞针40的宽度，从而便于从更换开口213处取放撞针40。更换开口213远离撞针40的一端具有卡扣定位缺口2131。
左外机壳211以及右外机壳212的内侧面还具有网格状的加强筋，以及用于承托、固定住电机等内部部件的结构，同时左外机壳211以及右外机壳212还具有多个散热、排气用的通孔，左外机壳211以及右外机壳212的具体结构为现有技术不再详细说明。
撞针挡板22可拆卸地安装在更换开口213上，当撞针挡板22被拆卸下时，更换开口213露出，即可通过更换开口213便捷地更换撞针40；当撞针挡板22安装上时，主体机壳21与撞针挡板22构成一体的外壳20，整体结构强度更高，并且使撞针40、电机等内部部件完全封闭在外壳20内，对这些内部部件起到保护作用，同时也在射钉过程中对操作者起到保护作用。
图4是本发明实施例中撞针挡板的立体图。
如图2、图4所示，撞针挡板22包括挡板内侧面221以及挡板外侧面222，当撞针挡板22安装在更换开口213上时，挡板内侧面221朝向撞针40。撞针挡板22还包括卡扣223、一对安装通孔224以及一对支撑凸起225。
挡板内侧面221具有网格状的加强筋，用于加强撞针挡板22的结构强度。加强筋由多个凸条构成。
图5是本发明实施例中卡扣与卡槽相卡合的结构示意图。
如图4-5所示，卡扣223设置在挡板内侧面221上，卡扣223与左外机壳211的卡槽2113相匹配，撞针挡板22和主体机壳21能够通过卡扣223以及卡槽2113相卡合，从而限制撞针挡板22朝射钉方向的移动。
具体地，卡扣223包括从挡板内侧面221大致垂直向下延伸的第一延伸部2231以及从第一延伸部2231的端部沿撞针挡板22的长度方向延伸的第二延伸部2232。第二延伸部2232伸入卡槽2113使卡扣223与卡槽2113相卡合。卡扣223也和卡扣定位缺口2131相匹配，安装时能够通过卡扣定位缺口2131将卡扣223定位至预定的装入位置，也即卡槽2113的开口处。即，将卡扣223对准卡扣定位缺口2131并按下后，沿射钉方向推动撞针挡板22即可使卡扣223与卡槽2113相卡合，沿蓄能方向推动撞针挡板22即可使卡扣223脱离卡槽2113。
挡板外侧面222上具有多个防滑凸起2211，用于在推动撞针挡板22使卡扣223卡合或脱离时增加摩擦力。多个防滑凸起2211按上述的往复运动方向排布且间隔均匀，并且每个防滑凸起2211的长度方向垂直于往复运动方向。
安装通孔224用于将撞针挡板22安装至撞针驱动组件30。两个挡板紧固件226分别穿过两个安装通孔224以及撞针驱动组件30上的挡板安装孔341，将撞针挡板22固定安装至撞针驱动组件30。安装通孔224和卡扣223分别设置在撞针挡板22沿其长度方向的两侧，其中安装通孔224设置在靠近撞针40的一侧。
支撑凸起225用于在撞针挡板22安装至主体机壳21上后对撞针挡板22起到支撑作用，避免撞针挡板22因受力而卡入更换开口213。一对支撑凸起225分别位于撞针挡板22沿其宽度方向的两侧，并且一对支撑凸起225的形状及位置分别与一对承托凸起(即上述的左承托凸起2112以及右承托凸起2122)的形状及位置相对应。撞针挡板22安装至主体机壳21上后，一对支撑凸起225分别与一对承托凸起相抵接。
撞针驱动组件30用于驱动撞针40沿预定的往复运动方向运动。撞针驱动组件30包括活塞31、弹簧32、枪嘴33、规制框架34、导向杆35以及弹匣36。
活塞31用于带动撞针40沿预定的往复运动方向运动。活塞31具有撞针嵌槽312，用于固定安装撞针40。
如图3所示，活塞31具有从其主体部分朝向撞针挡板22延伸的撞针连接部 311，安装完成后，撞针连接部311的朝向撞针挡板22的表面为支撑面，撞针连接部311具有从支撑面中部朝向撞针挡板22延伸的连接柱313，用于连接撞针40。连接柱313呈圆柱状，其延伸方向与撞针连接部311的支撑面相垂直，且与上述往复运动方向相垂直。此外，如图2所示，在撞针挡板22拆卸下后，撞针连接部311从更换开口213处露出，从而可从更换开口213处更换撞针40。
弹簧32为活塞31的运动提供动力。
枪嘴33用于容置撞针40，并在撞针40进行撞击射钉时对撞针40的活动进行限位。
图6是本发明实施例中枪嘴的结构分解图。
如图2、图6所示，枪嘴33包括撞针容置件331以及盖板332。
撞针容置件331具有一个凹槽，撞针容置件331与盖板332安装到一起时，该凹槽与盖板332朝向该凹槽的表面之间形成撞针容置槽3312，用于容置撞针40。撞针容置槽3312具有与更换开口213的长度方向一致的容置槽开口3311，用于插入及抽出撞针40。如图2所示，更换开口213在容置槽开口3311所在的平面上的投影覆盖容置槽开口3311，也即更换开口213使容置槽开口3311完全露出。
规制框架34用于在射钉过程以及蓄能过程中对活塞31的运动进行规制、限位。规制框架33为矩形框架，活塞31以及弹簧32均设置在规制框架33内，并且规制框架33的两个平行的规制侧板夹持住活塞31。其中活塞31设置在靠近射钉口的一侧，弹簧32的一端与活塞31相抵接，另一端与规制框架33远离射钉口的一侧相抵接。
规制框架34靠近射钉口的位置设置有上述的两个挡板安装孔341，挡板安装孔341与上述的挡板紧固件226相匹配。
导向杆35与规制框架34配合对活塞31的运动进行规制、限位。导向杆35的一端固定安装在活塞31上，另一侧与规制框架34远离射钉口的一侧连接，并且导向杆35的延伸方向与预定的往复运动方向相一致。弹簧32套装在导向杆35上。
弹匣36用于容纳射钉，多个射钉依次排列存储在弹匣36中。此外，枪嘴33和弹匣36连接在一起，可作为一个整体进行拆装。
撞针40用于撞击射钉。
图7是本发明实施例中撞针的立体图。
图8是本发明实施例中撞针安装在活塞上的结构示意图。
如图2、图6-8所示，撞针40包括撞针尾部41以及引导撞击部42。
撞针尾部41用于将撞针40安装至撞针驱动组件30。撞针尾部41呈方形板状，撞针尾部41中部开设有圆形的安装孔411，活塞上的连接柱313的形状与安装孔411相匹配，具体地，连接柱313呈圆柱状，其直径略小于安装孔411的直径，本实施例中，连接柱313的延伸长度略大于安装孔411的深度。
引导撞击部42用于撞击射钉。引导撞击部42与撞针尾部41一体形成，引导撞击部42呈长条形板状，连接至撞针尾部41一侧中部。撞针尾部41和引导撞击部42的连接位置处呈弧形。
引导撞击部42的一面上具有引导槽421，用于在射钉过程中规制撞针40的运动方向。上述的撞针容置槽3312也具有与引导槽421相匹配的槽状结构，因此引导撞击部42能够从容置槽开口3311处插入撞针容置槽3312，并与撞针容置槽3312可滑动地嵌合。
撞针40安装在活塞31上时，连接柱313穿过并嵌合在安装孔411中，板状的撞针尾部41与活塞31上的支撑面313相抵接，引导撞击部42可滑动地嵌合在撞针容置槽3312中。
因此，在卸下撞针挡板22后，更换开口213露出，撞针40的撞针尾部41以及对应的撞针固定件44从更换开口213露出，此时就可以方便地拆卸下待更换的撞针40。在拆卸下待更换的撞针40后，容置槽开口3311从更换开口213露出，此时就可以方便地将新的撞针40通过容置槽开口3311插入撞针容置槽3312进行安装。
图9是本发明实施例中更换撞针的流程图。
如图9所示，基于上述的射钉枪10以及快速更换安装的撞针机构12，本实施例中，更换射钉枪10中的撞针40的过程包括如下步骤：
步骤S1-1，用螺丝刀分别卸下两个挡板紧固件226，然后进入步骤S1-2；
步骤S1-2，按住撞针挡板22上的防滑凸起2221并沿指示凸起2222所指示的方向推动，使卡扣223从卡槽2113中脱出，然后进入步骤S1-3；
步骤S1-3，将撞针挡板22移开，使更换开口213露出，然后进入步骤S1-4；
步骤S1-4，将待更换的撞针40的撞针尾部41翘起，使其与活塞31上的连接柱313脱离，然后进入步骤S5；
步骤S1-5，将待更换的撞针40从撞针容置槽3312中抽出，然后进入步骤S1-6；
步骤S1-6，将新的撞针40从容置槽开口3311处插入撞针容置槽3312，并调整插入深度，使撞针尾部41的安装孔411对准活塞31上的连接柱313并嵌入，然后进入步骤S1-7；
步骤S1-7，将撞针挡板22对准更换开口213，并使卡扣223对准卡扣定位缺口2131，将撞针挡板22盖上更换开口213，然后进入步骤S1-8；
步骤S1-8，按住撞针挡板22上的防滑凸起2211并沿指示凸起2212所指示的反方向推动，使卡扣223扣入卡槽2213中，然后进入步骤S1-9；
步骤S1-9，将两个挡板紧固件226分别插入撞针挡板22的两个安装通孔224并用螺丝刀旋紧，然后进入结束状态。
如上所述，通过本实施例的快速更换安装的撞针机构12以及射钉枪10，能够拆卸下撞针挡板22并通过更换开口213方便快捷地更换撞针40，并能同样方便快捷地将撞针挡板22再安装上，使射钉枪10快速恢复可工作状态。
实施例一作用与效果
根据本实施例提供的快速更换安装的撞针机构及射钉枪，由于撞针挡板可拆卸地安装在外机壳的开口上，且开口位置与撞针的安装部相对应，因此可以拆下撞针挡板，通过开口更换撞针，而无需拆开整个机壳、取出及拆装大量内部部件；由于撞针上具有安装孔，活塞上具有与撞针的安装孔形状相匹配的连接柱，因此使活塞上的连接柱嵌入撞针上的安装孔即可将两者连接，而无需设置插销、螺钉等连接件，减少了零部件的数量，且避免了这些较小的零部件的遗失情况，同时也减少了更换安装的步骤，对于普通用户来说，大大简化了更换撞针的操作。
具体地，撞针尾部上具有圆形的安装孔，活塞具有朝向可拆卸的撞针挡板的撞针连接部，其朝向撞针挡板的上表面为支撑面，支撑面上具有朝向撞针挡板延伸出的连接柱，连接柱为撞针的圆形安装孔相匹配的圆柱，且延伸方向与往复运 动方向相垂直，因此，卸下撞针挡板后，即可从主体机壳的更换开口处更换撞针，在更换时，只需要将待更换的撞针尾部翘出，使其与连接柱脱离，再将新撞针安装入，使其撞针尾部的安装孔与活塞的连接柱相嵌合即可完成两者的连接，而不需要再通过插销、螺钉连接撞针和活塞。此外，连接柱与活塞的其他部分一体形成，因此也不会增加额外的制造工序。
<实施例二>
图10是本实施例中射钉枪的结构分解图。
图11是图10中框A内部分的放大图。
如图11-12所示，本实施例提供一种快速更换安装的撞针机构12及射钉枪10，与实施例一相比，区别之处在于，本实施例的活塞31的结构有所不同。
图12是本实施例中活塞的侧视图。
如图11-12所示，与实施例一相比，本实施例的活塞31还具有撞针限位部314，用于对撞针40尾部进行限位。撞针限位部314整体从撞针连接部311朝向撞针挡板22方向延伸出，具体地，撞针限位部314呈钩状，包括第一延伸段3141和第二延伸段3142，其中第一延伸段3141从撞针连接部311的远离枪嘴33的一侧边缘垂直向上延伸，即延伸方向与支撑面313相垂直，且延伸方向及宽度方向均与往复运动方向相垂直；第二延伸段3142从第一延伸段3141延伸出的端部朝向枪嘴33方向延伸，延伸方向与第一延伸段3141相垂直，且与往复运动方向平行，宽度方向与往复运动方向垂直，从而形成钩状，可扣住撞针尾部41。
此外，如图11-12所示，在规制框架34上，挡板安装孔341前方(更靠近枪嘴33的位置)还具有一对弹匣连接孔342，枪嘴33和弹匣36通过连接件343(螺钉)安装在弹匣连接孔342处，枪嘴33和弹匣36可作为一个整体进行拆装。
图13是本实施例中撞针的主视图。
图14是本实施例中撞针的侧视图。
如图12-14所示，第二延伸段3142与撞针连接部311之间的距离大于撞针40的厚度，即图中L3>L5；第一延伸段3141到连接柱313之间的距离大于撞针40一端到安装孔411的距离，由于连接柱313和直径和安装孔411的直径基本一致，这也就等价于图中L1>L4。沿往复运动方向，第二延伸段3142的端部 与连接柱313之间的距离小于撞针40一端到安装孔411的距离，这也就等价于图中L2<L4。
图15是本实施例中以斜插方式安装撞针的结构示意图。
图16是本实施例中撞针与活塞的连接结构示意图，即完成撞针安装后撞针与活塞的连接状态。
如图15-16所示，由于上述的结构及尺寸设置，因此在安装时，可以将撞针40的撞针尾部41斜插入钩状的撞针限位部314中，即撞针40沿其长度方向倾斜，再将撞针40向下放平，从而使连接柱313嵌入安装孔411中；也可以从侧面将撞针40倾斜放入，撞针40沿其宽度方向倾斜，再将撞针40转动放平，从而使连接柱313嵌入安装孔411中，完成撞针40和活塞31的连接。
此外，由于具有撞针限位部314，为避免撞针40安装时受到较大弯折而影响其撞击射钉时的力度和稳定性，在安装过程中最好先将枪嘴33和弹匣36整体拆卸下，将撞针40与活塞31按上述方式连接后，再将枪嘴33和弹匣36整体装上，装上时使撞针40的引导撞击部42嵌入撞针容置槽3312。
撞针40的结构与实施例一中相同，为便于说明本实施例的活塞31结构的作用，将撞针40尾部的面记作受力面412，也即撞针尾部41的一个侧面，该侧面为撞针尾部41远离引导撞击部42的侧面，受力面412与往复运动方向垂直。
安装完成后，撞针40尾部嵌在钩状的撞针限位部314中，在射钉时(即活塞31沿D1方向移动时)，不仅通过连接柱313向撞针40施力，同时第一延伸段3141与受力面412相抵接，还通过第一延伸段3141直接向撞针40一端施力。此外，第一延伸段3141、第二延伸段3142还在运动过程中对撞针40尾部起到规制作用。
图17是本实施例中更换撞针的流程图。
如图17所示，本实施例中，更换撞针40的流程具体包括如下步骤：
步骤S2-1，用螺丝刀分别卸下两个挡板紧固件226，然后进入步骤S2-2；
步骤S22，按住撞针挡板22上的防滑凸起2221并沿指示凸起2222所指示的方向推动，使卡扣223从卡槽2113中脱出，然后进入步骤S2-3；
步骤S2-3，将撞针挡板22移开，使更换开口213露出，然后进入步骤S2-4；
步骤S2-4，将枪嘴33及弹匣36整体拆卸下，待更换的撞针40的引导撞击 部42离开枪嘴33，然后进入步骤S2-5；
步骤S2-5，将待更换的撞针40的引导撞击部42将上翘起，使撞针尾部41从连接柱313脱离，然后将撞针40取出，然后进入步骤S2-6；
步骤S2-6，将新的撞针40从更换开口213放入，将撞针尾部41斜插入钩状的撞针限位部314中，再将引导撞击部42压下，使连接柱313嵌入撞针尾部41的安装孔411，然后进入步骤S2-7；
步骤S2-7，将枪嘴33及弹匣36整体安装上，装上时使引导撞击部42嵌入枪嘴33的撞针容置槽3312，然后进入步骤S2-8；
步骤S2-8，将撞针挡板22对准更换开口213，并使卡扣223对准卡扣定位缺口2131，将撞针挡板22盖上更换开口213，然后进入步骤S2-9；
步骤S2-9，按住撞针挡板22上的防滑凸起2211并沿指示凸起2212所指示的反方向推动，使卡扣223扣入卡槽2213中，然后进入步骤S2-10；
步骤S2-10，将两个挡板紧固件226分别插入撞针挡板22的两个安装通孔224并用螺丝刀旋紧，然后进入结束状态。
本实施例中，其他结构与实施例一中相同，因此不再重复说明。
实施例二作用与效果
根据本实施例提供的快速更换安装的撞针机构及射钉枪，由于同样具有可拆卸的撞针挡板，撞针上有安装孔，活塞上有与安装孔相匹配的连接柱，因此同样能够实现便捷的撞针更换安装。
进一步，本实施例的活塞还具有钩状的撞针限位部，包括垂直于支撑面延伸出的第一延伸段和从第一延伸段端部进一步延伸出的第二延伸段，第一延伸段的延伸方向与宽度方向均与往复运动方向垂直，因此在活塞运动过程中，撞针限位部能够对撞针尾部进行限位，进一步规制撞针尾部的活动，避免其发生偏转等情况，从而进一步提高射钉的稳定性。此外，在射钉过程中，还能够通过撞针限位部直接地向撞针长度方向的一端施力，相较于实施例一中仅通过连接柱向撞针施力的方式，本实施例的方式还能够提高射钉的力度和稳定性，或是在同等射钉力度的情况下可降低撞针的结构强度要求。
上述实施例仅用于举例说明本发明的具体实施方式，而本发明不限于上述实 施例的描述范围。
在上述实施例中，连接柱313的延伸长度略大于撞针40安装孔411的深度，在替代方案中，连接柱313的延伸长度也可以等于或略小于安装孔411的深度，也不影响活塞31和撞针40的连接，也能实现相应的技术效果。
