Description

—— 才几才巨 技术领域
本发明涉及一种机拒。 背景技术
业界常用的通信机拒往往包括机拒本体和底座， 这两个部分可以拆分便于 运输， 而当需要安置通信机拒时， 则可以通过紧固螺钉将机拒本体和底座固定 在一起。 在安置通信机拒时， 考虑到空间利用率的问题， 在安装各种通信机拒 时， 常常会将两个通信机拒背靠背安置， 或者将通信机拒靠墙安置。 在这种情 况下， 机拒本体后部与底座的固定连接就会有诸多不便， 比如必须先将机拒本 体和底座的后部用紧固螺钉固定好然后再放入安置地， 而当需要更换机拒本体 时， 又只能先将整个机拒拉出再松动紧固螺钉， 工作量巨大， 对于设备的日常 维护不利。 发明内容
为了解决机拒靠墙安装时,底部靠墙端无法有效固定的技术问题,本发明提 供一种机拒， 其包含机拒底座和机拒本体。 所述机拒底座用于承载所述机拒本 体。 所述机拒本体包含相对设置的前柱和后柱， 所述前柱与所述后柱之间设有 梁， 梁的两端分别固定所述前柱和所述后柱。 所述梁上设有导向块， 所述前柱 和所述后柱上设有定位孔， 所述后柱的定位孔中收容有紧固螺钉， 所述机拒还 包括紧固杆， 所述紧固杆穿过所述前柱上的定位孔， 并在所述导向块的支撑下 指向所述紧固螺钉的螺帽， 以用于扭紧或松动所述紧固螺钉， 且当所述紧固螺 钉被扭紧时， 所述紧固螺钉自所述后柱上穿出并与所述机拒底座上的底座压块 相配合， 以将所述机拒本体和所述机拒底座固定连接。
在安置本发明实施例所提供的机拒时， 操作员可以通过紧固杆在机拒的前 方将机拒本体后部与机拒底座固定在一起， 操作简单。 附图说明
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例中所需要使 用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些 实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可 以根据这些附图获得其他的附图。
图 1为本发明实施例中机拒的局部放大示意图；
图 2为本发明实施例的机拒中的导向块的放大示意图。
图 3为本发明实施例的机拒中的紧固杆的放大示意图。 具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅是本发明一部分实施例， 而不是全 部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造性 劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
请参考图 1,图 1为本发明实施例机拒的局部放大示意图。 如图 1所示， 机 拒包含机拒本体 22以及机拒底座 24, 所述机拒底座 24用于承载所述机拒本体 22。
机拒本体 22包括相对设置的前柱 220和后柱 222。 所述前柱 220和所述后 柱 222之间设有梁 221，所述梁 221的两端分别与所述前柱 220和后柱 222固定 连接。 所述前柱 220和所述后柱 222上分别设有一定位孔。 在本发明实施例中， 所述前柱 220和所述后柱 222上的定位孔均为通孔；所述梁 221与所述前柱 220 和后柱 222垂直连接。 在其他可选择的实施例中， 所述梁 221也可以与所述前 柱 220和后柱 222以一定的角度固定连接。
所述梁 221上固设有导向块 227， 在本发明实施例中， 所述导向块 227下部 设有固定孔， 用于通过紧固螺钉等紧固件将所述导向块 227与所述梁 221 固定 连接。 所述前柱 220和所述后柱 222之间还设有一紧固杆 228。 所述紧固杆 228 的前端穿过所述前柱 220上的定位孔自所述机拒的前部伸出， 所述紧固杆 228 的尾部在所述导向块 227的支撑下指向所述后柱 222上的定位孔。所述后柱 222 上的定位孔中收容有紧固螺钉 226。 所述紧固螺钉 226的螺帽与所述紧固杆 228 相对。 在实际应用中， 操作员可以在机拒前部通过所述紧固杆 228扭紧或松动 所述后柱 222上的紧固螺钉 226， 且当所述紧固螺钉 226被扭紧于所述后柱 222 上的定位孔中时， 所述紧固螺钉 226的末端自所述后柱 222上伸出并与凸设于 所述底座 24后部的底座压块 242的固定孔相配合， 以将所述机拒本体 22的后 部和所述底座压块 242的后部固定连接。 所述紧固杆 228的尾部设有与所述紧 固螺钉 226的螺帽上的 HJ槽相配合的凸起， 用于扭紧或松动所述紧固螺钉 226。
请进一步参照图 2， 在本发明实施例中， 所述导向块 227 中空且设有前壁 2274和后壁 2276， 所述前壁 2274和所述后壁 2276分别与所述前柱 220和所述 后柱 222相对设置。 所述前壁 2274上设有前壁孔 2275。 所述后壁 2276上设有 后壁孔 2277。所述前壁孔 2275和所述后壁孔 2277相对应，且所述前壁孔 2275、 所述后壁孔 2277、 所述前柱 220上的定位孔、 所述后柱 222上的定位孔均处于 同一条直线上。 所述紧固杆 228穿过所述前壁孔 2275， 从而所述紧固杆 228在 所述前壁 2274的支撑下指向被收容于所述后柱 222的定位孔中的紧固螺钉 226。 在本发明实施例中， 所述前壁孔 2275、 所述后壁孔 2277、 所述前柱 220上的定 位孔、 所述后柱 222上的定位孔处于同一条直线上是指在不考虑紧固杆 228的 长度的情况下， 紧固杆 228可以同时穿过所述前壁孔 2275、 所述后壁孔 2277、 所述前柱 220上的定位孔、 所述后柱 222上的定位孔， 本发明实施例中所述前 壁孔 2275、 所述后壁孔 2277、 所述前柱 220上的定位孔、 所述后柱 222上的定 位孔处于同一条直线上包括：所述前壁孔 2275、所述后壁孔 2277、所述前柱 220 上的定位孔、 所述后柱 222 上的定位孔均为规则孔， 而且这四个孔的孔心处于 同一条直线上的情况； 以及所述前壁孔 2275、 所述后壁孔 2277、 所述前柱 220 上的定位孔、 所述后柱 222 上的定位孔中的任意一个或多个为不规则孔， 但是 在不考虑紧固杆 228 的长度的情况下， 紧固杆仍然可以同时穿过这四个孔的情 况。
进一步的， 在本发明实施例中， 所述前壁孔 2275和后壁孔 2277的形状可 以为圓形， 也可以为橢圓形。 但是， 所述前壁孔 2275的最小孔径要小于所述紧 固螺钉 226的螺帽的直径，所述后壁孔 2277的最小孔径要大于所述紧固螺钉 226 的螺帽的直径。 所述后壁 2276与所述后柱 222间的垂直距离小于所述后柱 222 的厚度，而所述前壁 2274与所述后柱 222间的垂直距离也小于所述紧固螺钉 226 的长度， 从而当所述紧固螺钉 226被所述紧固杆 228扭松后其螺帽可以穿过所 述后壁孔 2277并被收容于所述导向块 227的前壁 2274和后壁 2276间的空腔中 而不会脱落。 在本发明实施例中， 所述孔的最小孔径是指能纵向穿过孔的圓柱 体的最大截面圓的直径。 请参考图 3， 图 3为紧固杆的放大结构示意图。 紧固杆 228包含头部 2280 以及尾部 2282， 紧固杆 228的尾部 2282位于所述紧固杆 228的指向所述后柱 222的一端， 且所述尾部 2282包含与紧固螺钉 226的螺帽上的凹槽相匹配的凸 起。 在本发明实施例中， 所述紧固杆 228上还可以设有一个可以卡接挡圈的凹 槽 2281， 用于防止紧固杆 228从前柱 220上的定位孔或者导向块 227上的前壁 孔 2275中中脱出。 在其他可选择的实施方式中， 还可以紧固杆 228上增加一减 震护套， 以防止紧固杆 228在受到震动时， 与导向块接触的部位发出异响。
由上述描述可知， 当机拒本体还未完全推入时， 紧固螺钉末端被收容于后 柱的定位孔中，， 紧固杆穿过所述前柱的定位孔并在导向块的支撑下指向所述紧 固螺钉的螺帽。 在进行安装操作的过程中， 将机拒从正面推入， 使后柱与底座 压块紧密接触。 当后柱与底座压块紧密接触后， 操作员即可从机拒正面操作紧 固杆， 通过紧固杆旋动紧固螺钉， 使得紧固螺钉旋入到底座压块的固定孔内锁 死， 从而达到将底座压块与后柱固定的效果。
综上所述， 本发明机拒本体预安装有紧固杆， 且导向块对紧固杆以及紧固 螺钉进行支撑， 使紧固杆的凸起部始终指向紧固螺钉， 以方便对紧固螺钉进行 操作。。
以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局限于 此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到 变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应 所述以权利要求的保护范围为准。
