Description

一种能够取卸光模块的防尘帽 技术领域
本发明属于通信基站设备领域，具体涉及一种能够取卸光模块的防尘帽。
背景技术
通信基站上传输光信号的主要器件是光模块，其安装位置大部分是在设备内，当设备上装入光模块，且外部装上插座后，光模块的取卸有以下手段：1、直接用手取卸，如图1所示；2、将插座取下，用手取卸，如图2所示；3、直接使用定制工具进行取卸，如图3所示。这几种取卸方法分别存在以下缺点：1、当光模块的位置很深或者插座太长时，很难实现手工直接取卸；2、插座往往是靠螺钉固定在设备面板上，先拆卸插座，再手工取卸的过程复杂；3、通信设备的安装环境千差万别，单独的定制工具存在易丢失，或者需要使用时无法找到等突发状况，无法满足拆卸需求。
发明内容
本发明的目的是提供一种能够取卸光模块的防尘帽，利用防尘帽上设置的取卸钩实现光模块的取卸，且防尘帽和连接器的插座或插头连接，从而在需要取卸光模块时可以无需拆卸插座，方便快捷的将光模块取下。
为了实现上述目的，本发明所采用的技术方案是：一种能够取卸光模块的防尘帽，包括防尘帽本体，防尘帽本体的表面设置有用于取卸光模块的取卸钩，取卸钩具有用于将光模块拉出的弯钩。
所述防尘帽本体的表面设置有安装座，所述取卸钩活动连接在所述安装座上。
作为第一种设置方式，所述取卸钩以滑动的方式连接在所述安装座上。
进一步的，所述安装座上设置有滑槽，滑槽底面设有至少两个沟槽，所述取卸钩的钩柄滑动设置在滑槽中，且钩柄上设有弹爪，在取卸钩的滑动过程中，弹爪能够卡入不同的沟槽中。
再进一步的，所述滑槽的两侧内壁设置为第一斜面，所述取卸钩的钩柄两侧设有和第一斜面配合的第二斜面。
作为第二种设置方式，所述取卸钩以转动的方式连接在所述安装座上。
进一步的，所述安装座上设有支撑面，用于在取卸钩的取卸工作中支撑取卸钩的钩柄。
所述安装座上设置有收纳槽，取卸钩通过转动带动其端部的弯钩进出收纳槽；收纳槽 内设置有止挡面，在取卸钩的弯钩进入收纳槽后，取卸钩的钩柄支撑在止挡面上。
作为一种选择，所述收纳槽内设有容纳弯钩的弯钩槽。
进一步的，所述取卸钩上设有和所述收纳槽内壁配合的过盈凸起。
更进一步的，所述收纳槽的两侧设有便于拉出取卸钩的取卸口。
或者，取卸钩的弯钩进入收纳槽后，取卸钩上远离弯钩的一端露出收纳槽，以形成按压取卸钩的按压头。
本发明的有益效果是：本发明将取卸钩集成在插座或插头上的防尘帽上，可以避免取卸钩的丢失，在需要取卸光模块时，通过取卸钩方便快捷的将光模块从设备上取下。
本发明取卸钩以滑动抽拉的方式连接在防尘帽上，通过取卸钩上弹爪和滑槽上不同位置沟槽的配合，使得取卸钩在防尘帽的安装座上具有工作和非工作两个状态位置，在非工作状态时的取卸钩的弯钩端部顶在安装座上，从而避免弯钩被碰撞变形损坏，在工作状态时，取卸钩伸出一定的长度，可以利用取卸钩的弯钩将光模块取出。在所设置的沟槽中，位于最内侧的沟槽和取卸钩的非工作状态对应，其余的沟槽均和取卸钩的工作状态对应，并可以实现取卸钩的不同伸长长度，以应对光模块的不同安装深度。
本发明取卸钩和滑槽之间通过第一斜面和第二斜面的配合，实现对取卸钩上下定位，同时起到引导安装取卸钩的作用。
本发明中取卸钩通过可转动的折叠方式连接在防尘帽上，使得取卸钩在防尘帽的安装座上具有工作和非工作两个状态位置，在非工作状态时的取卸钩可以将弯钩收进安装座的收纳槽中，以避免弯钩被碰撞变形损坏，在工作状态时，取卸钩的弯钩露出安装座的收纳槽，且取卸钩远离弯钩的一端顶在安装座的支撑面上，由支撑面为取卸钩的取卸动作提供支撑。
本发明中取卸钩钩柄上设置过盈凸起，可以将取卸钩卡在收纳槽内，避免松动脱落，在其中一个实施方式中，收纳槽两侧设置的取卸口又便于将取卸钩从收纳槽中取出；在另一个实施方式中，取卸钩远离弯钩一端露出收纳槽形成按压头，便于借助杠杆原理通过按压的动作将取卸钩从收纳槽中取出。

具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明，但并不作为对发明做任何限制的依据。
本发明提出的一种能够取卸光模块的防尘帽的结构如图4所示，包括防尘帽本体5和设置在防尘帽本体5外侧的取卸钩6，防尘帽本体5通过线绳7等连接件连接在需要防尘的连接器(如插头或插座)上，以避免防尘帽丢失，图4中需要防尘的连接器为插头4。
所述取卸钩6在防尘帽本体5上的安装可以采用多种结构形式，下面结合具体的实施例和相应的附图对其进行详细的说明。
实施例1：参照附图5-9所示，本实施例中，在防尘帽本体5的前端设置一个安装座8，用以取卸钩6的安装。所述的安装座8上设置有滑槽801，滑槽801允许的滑动方向为防尘帽本体5的轴向。所述取卸钩6的钩柄601滑动设置在滑槽801内，随着取卸钩6的滑动，可以调整取卸钩6前端的弯钩603的伸出长度。
为了避免取卸钩6从滑槽801中滑脱，同时又为了可以在取卸钩6钩取光模块时给 取卸钩6提供支撑，在滑槽801的槽底沿取卸钩的滑动方向间隔设置至少两个沟槽803，相应的在取卸钩6的钩柄601上设置有能够卡在沟槽803内的弹爪602。取卸钩6的弹爪卡入滑槽801最内侧的一个沟槽803时，取卸钩处于非工作状态，此时取卸钩6的弯钩603开口位置顶在安装座8上，无法进行光模块的取卸，又可以保护弯钩603免受磕碰破坏；取卸钩6在沿滑槽801向外滑动的过程中，弹爪602可以与除滑槽801最内侧外的其他不同沟槽803配合，使得取卸钩6伸出滑槽801不同的长度，满足不同使用场景的取卸需要，此时取卸钩6处于工作状态。如光模块的位置较深时，可以增加取卸钩6伸出的长度，以便取卸钩6的弯钩603可以深入光模块的位置进行取卸工作。
如图6所示，本实施例中，滑槽801内设置有两个沟槽803，分别为取卸钩6处于两个状态时所在的位置。位于内侧的沟槽803对应取卸钩6的非工作状态，如图9所示，取卸钩6的弹爪602卡在该沟槽803内以后，可以避免取卸钩6的脱落，此时取卸钩6的弯钩602收回，弯钩602的端部贴紧安装座8，以保护取卸钩6免受碰撞等。位于外侧的沟槽803对应取卸钩6的工作状态，如图8所示，取卸钩6的弹爪602卡在该沟槽803内以后，取卸钩6伸出一定的长度，可以钩取光模块，实现光模块的拆卸，由于取卸钩6的弹爪602卡在沟槽803内，因此在钩取光模块时可以给取卸钩6提供一定的支撑。
如图7所示，所述取卸钩6上的弹爪602包括设置在取卸钩6腹面的一个弹片以及设置在弹片活动端的尖端，弹片悬置在取卸钩6的弹片活动槽605内，并与弹片活动槽605的顶部之间留有活动间隙，这样弹片就可以上下活动。弹片上的尖端设置有挤压斜面。
继续参考图6，为了避免取卸钩6在滑槽801内晃动，所述滑槽801的两侧内壁设置为第一斜面802，所述取卸钩6的钩柄601两侧设有和第一斜面802配合的第二斜面604，取卸钩6装在滑槽801内以后，第一斜面802压在第二斜面604上，并和滑槽801的槽底配合将取卸钩6夹在第一斜面802和槽底之间，避免取卸钩6的上下左右松垮晃动。此外，第一斜面802和第二斜面604配合还可以引导取卸钩6顺利装入滑槽801。
实施例2：参照附图10-13所示，本实施例中，取卸钩6远离弯钩603的一端通过销轴以转动的方式连接在安装座8上，安装座8上设置有收纳槽804。取卸钩6通过转动进出收纳槽804，在取卸钩6全部进入收纳槽804时，取卸钩6处于非工作状态，无法钩取光模块，如图10、11所示，此时由收纳槽804内的止挡面808支撑取卸钩6的钩柄。取卸钩6通过转动离开收纳槽804时，取卸钩6上除了远离弯钩603的一端通过销轴和收纳槽804保持连接外，其余部分悬置在收纳槽804以外，如图12、13所示，此时的取卸钩6处于工作状态，可以钩取光模块。
进一步的，如图12所示，取卸钩6的两侧分别设置有过盈凸起606，在取卸钩6进入收纳槽804以后，过盈凸起606可以和收纳槽804的两侧壁过盈配合，以避免取卸钩6松动。
更进一步的，如图10所示，在收纳槽804两侧分别设置一个取卸口805，两个取卸口805相对设置，便于手指伸入取卸口805将取卸钩6从收纳槽804中拉出。
为了保护取卸钩6的弯钩603，在收纳槽804内还设置有弯钩槽806，取卸钩6折叠进入收纳槽804以后，弯钩603位于弯钩槽806内，如图11所示。
所述收纳槽804的槽底形成所述的止挡面808，取卸钩6进入收纳槽804后，止挡面808可以支撑取卸钩6；止挡面808向前延伸越过销轴的部分形成支撑面807，可以对处于工作状态的取卸钩6进行支撑，且支撑点位于背离弯钩603的取卸钩背面，从而满足取卸钩6在取卸光模块时的支撑需要。由于止挡面808和支撑面807分别位于收纳槽804槽底的不同位置，因此取卸钩6在旋转进出收纳槽804的过程中，旋转角度为180°。
实施例3：参照附图14-17所示，本实施例中，取卸钩6仍通过远离弯钩603的一端所设置的销轴转动连接在安装座8上，安装座8上设置收纳槽804，取卸钩6通过转动可以进出收纳槽804。
如图17所示，所述安装座8上设置支撑钩柄的支撑面807，取卸钩6从收纳槽804转动出来后，钩柄上和弯钩603相背的一面通过顶在支撑面807上获得取卸钩6在取卸光模块过程中所需的支撑力。
如图17所示，所述收纳槽804内设置有倾斜的止挡面808，止挡面808和所述支撑面807形成锐角夹角。取卸钩6转动进入收纳槽804以后，取卸钩6上与弯钩603相背的一面抵在止挡面808上，如图15所示，此时取卸钩6整体呈倾斜姿态，弯钩603朝向收纳槽804外，收纳槽804两侧边沿形成对弯钩603的保护。
进一步的，如图16所示，所述取卸钩6上设有和所述收纳槽804内壁配合的过盈凸起606，在取卸钩6进入收纳槽804以后，过盈凸起606可以和收纳槽804的两侧壁过盈配合，以避免取卸钩6松动。
更进一步的，如图14、15所示，取卸钩6进入收纳槽804以后，取卸钩6的尾端从收纳槽804中露出，作为按压头607，通过按压取卸钩6的按压头607，可以带动取卸钩6绕销轴旋转，从收纳槽804中出来，直至取卸钩6的钩柄顶在支撑面807上，如图16、17所示，此时可以利用取卸钩6进行光模块的取卸。
以上三个实施例中，取卸钩均是活动设置在安装座上，在具体实践中，还可以根据 需要，将取卸钩和安装座设置为一体结构，同样可以起到取卸光模块的作用。
以上实施例仅用以说明本发明的技术方案而非对其进行限制，所属领域的普通技术人员应当理解，参照上述实施例可以对本发明的具体实施方式进行修改或者等同替换，这些未脱离本发明精神和范围的任何修改或者等同替换均在申请待批的权利要求保护范围之内。
