一种把手 技术领域
本实用新型涉及通信信息技术领域， 尤其涉及一种应用于起拔可插拔 式小面板的把手。 背景技术
在通讯行业中，可插拔式小面板在 1U盒体结构及多插卡单板中被广泛 应用。 如图 1所示， 这是可插拔式小面板的一种典型结构， 主要由托盘 101 与印刷电路板 ( PCB, Printed Circuit Board ) 102组成； 其中， 托盘 101前 端为前面板 103, 前面板 103上装有松不脱螺钉 104。 另外由于用户需求， 通讯设备密集化和小型化发展日趋明显， 前面板 103 的尺寸被尽量压缩， 而接口器件又要求尽可能密集， 小面板往往没有足够空间用于安装起拔器 和普通拉手。 再加上 PCB板端插头与背板插座插接时存在较大的预应力， 直接拉扯松不脱螺钉旋钮非常费劲， 而且由于松不脱螺钉大多采用铆接工 艺， 多次拉扯容易脱落。 可插拔式小面板的起拔因此成为了一个难题。
目前， 行业内主要采用以下方法：
在面板底部设置扁平形拉手 201 ,如图 2所示。这种拉手的优点是起拔 力大， 手感好， 占用面板有效空间较小； 但也存在明显缺点：
( 1 ) 更改了面板结构， 占用了部分面板器件面空间；
( 2 ) 当几块带扁平形拉手的单板层叠使用时， 会阻碍其下面相邻单板 的布线；
( 3 ) 把手会影响小面板接口线缆的插拔。 发明内容

其中， 所述把手主体的上下表面可以设置为圆形、 正方形或不规则形 状等。 在拉拔所述可插拔式小面板时， 该把手主体 301 的上表面突出部分 只要能够提供足够大的接触面即可。
如图 4和 4A所示， 在本实用新型的具体实施例中， 所述 4巴手主体 301 包括手柄 3011、 贯穿该巴手主体的中心通孔、 底部螺纹孔 3015 和定位柱 3016;
如图 4所示， 该中心通孔包括： 容纳弹簧 303的顶部中心通孔 3012、 与不脱出螺钉 302的螺纹头 3023 (参见图 5 )螺纹匹配的中部螺纹孔 3013 和容纳不脱出螺钉 302的螺纹头 3023的底部中心通孔 3014;
顶部中心通孔 3012、弹簧 303和底部中心通孔 3014内径均大于中部螺 纹孔 3013。
另外， 所述把手主体 301底部中心通孔外侧设置有底部螺纹孔 3015 , 通过该底部螺纹孔 3015与螺钉 601结合的方式使该把手与可插拔式小面板 连接。
如图 4A所示，所述手柄 3011为把手主体 301外表面设置的突出部分； 所述把手主体 301底部还设置定位柱 3016,该定位柱 3016与可插拔式 小面板托盘上的定位孔 1013 (参见图 6 )对应。 使该把手与小面板的位置 相对固定， 便于安装。
如图 5所示， 为了与所述 I巴手主体 301的结构对应， 本实用新型中所 述不脱出螺钉 302可以设置为一端设置螺钉头 3021 , 另一端设置有带螺纹 的螺纹头 3023 ,连接螺钉头 3021与螺纹头 3023的导杆 3022直径小于螺钉 头 3021与螺纹头 3023直径； 螺纹头 3023的螺纹与把手主体 301的中部螺 纹孔 3013匹配。
其中， 不脱出螺钉 302结构如图 5所示， 不脱出螺钉的螺钉头 3021尺 寸较大， 侧面滚花， 便于手拧； 顶部设置十字槽或是一字槽， 便于使用螺 丝刀或者电动起子彻底紧固。 在具体的应用中本实用新型所提供的把手自身装配过程包括： 将弹簧 303放入 4巴手主体 301的顶部中心通孔 3012, 然后将不脱出螺 钉 302螺纹头部分 3023穿过弹簧 303插入顶部中心通孔 3012,并拧入中部 螺纹孔 3013 , 直到 3023全部穿出 3013; 此时， 弹簧 303 已经由原来的自 然状态被压缩， 从而产生一个反向的推力， 使不脱出螺钉 302与把手主体 301之间保持相对固定。
本实用新型与小面板的装配过程如 6所示。 托盘 101上安装把手的相 应位置上开有 2个沉头孔 1011 , 1个中心通孔 1012和 1个定位孔 1013。 将 把手按图示方向装到小面板托盘 101上， 并用 2枚沉头螺钉 601固定锁紧。 而螺钉可以从中心通孔 1012自由穿过。
本实用新型在小面板上的应用如图 7所示。 由图可知， 本实用新型在 使用过程中不占用面板有效空间， 同时具有螺钉不脱落、 拆装方便快捷、 固定可靠， 通用性好等优点。 当起拔力不大时， 可以直接使用把手主体 301 的手柄 3011起拔面板；
如图 8所示， 当起拔力较大， 直接拉手柄 3011不足以起拔面板时， 本 实用新型还提供一种起拔装置， 该装置包括两个图 3 所示的把手， 并且该 把手分别设置于可插拔式 '〗、面板托盘两端。
