Description

车间纖通风孔及盖觀件
技术领域
本发明涉及一种通风孔及盖板组件， 具体涉及无尘车间地板通风孔及盖板组件。 背景技术
在液晶面板等无尘车间， 为了保证生产区域的洁净度，通常在无尘车间地板上设有很多通 风孔，净化空气在设备的作用下经通风孔往下吹， 车间内的空气从车间两侧回流到空气净化设 备进行净化后循环。为了保证无尘车间内的气流流向，会在不同区域的通风孔上使 不同开孔 率的盖板， 从而保证生产区域内的气流垂直下吹和保证生产区域的洁净度。现有技术的通风孔 采用圆形孔， 与通风孔配合的盖板为圆形盖板， 盖板安装在通风孔使用过程中存在以下缺陷： 一是圆形盖板与圆形孔配合卡位不结实、不牢靠， 车辆及人员踩踏在上面^间长了容易出现盖 板松动； 二是圆形盖板与圆形孔配合时， 由于加工误差等缘故， 接触面容易出现不平整， 从而 导致圆形盖板在踩踏时容易出现侧翻， ffl于通风孔面积一般比较大， 一般通风孔直径在
20〜50cm, 盖板若安装不稳出现侧翻， 物品或人员会出现从通风孔掉落下去的危险。 发明内容
本发明所要解决的技术 题是，提供一种配合卡位结实、牢靠 ϋ不容易惻翻的无尘车间地 板通风孔及盖板组件。
本发明的技术解决方案是，提供一种具有以下结构的无尘车间地板通风孔及盖板组件，包 括若千个设在无尘车间地板上的通风孔和与通风孔配合的盖板，所述通风孔包括孔洞和设在孔 洞外周的卡槽， 盖板包括盖体和设在盖体外周的卡脚， 盖体与孔洞相配合， 所述卡脚与卡槽相 配合。
与现有技术相比，本发明的无尘车间地板通风孔及盖板组件具有以下优点： 由于在通风孔 的孔洞外周设有卡槽， 在盖板的盖体夕卜周设于卡脚， 在通风孔上安装盖体时， 增加了卡槽和卡 脚配合卡位， 使得通风孔与盖板的配合更结实、 更牢靠。 同时由于有卡槽和卡脚的存在， 盖板 与通风孔配合更加稳定， 卡槽和卡脚的配合也增加了接触面积， 在踩踏 ^不容易出现侧翻， 更 加安全可靠。
在一个优选的实施例中，所述卡槽沿孔洞周向均匀布置。卡槽沿孔洞均匀布置能使受力更 均匀， 即便出现磨损， 也不容易造成通风孔的损坏。
在一个实施例中， 卡槽为方形槽、 半圆形槽或弧形槽中的一种或组合。 方形槽、 半圆形槽 或弧形槽为比较规则的形状， 相对容易加工。在一个通风孔中， 优选多个卡槽为相同的结构或 形状， 如方形槽。 但不限于此， 也可以是多种结构或形状的结合， 如一个通风孔的六个卡槽， 相对称的两个卡槽为弧形槽， 另外四个为方形槽： 或者另外四个中相对的两个为方形槽， 还有 两个为半圆形槽。
在一个改进的实施例中， 卡槽的中部设有卡止凹槽， 卡脚的安装面上设有与凹槽配合的凸 起， 安装时， 卡止凹槽与凸起配合起到限制盖板的周向转动。 起到更好的限位和卡止作用， 使 得盖板与通风孔的配合更稳定、更牢靠。而且时间长了， 因为磨损容易造成卡脚与卡槽有相对 运动， 卡止凹槽和凸起起到二次稳定配合的作用， 能更好地限制盖板相对通风孔的周向转动。
在优选的实施例中， 卡止凹槽比卡槽深 0.5~2.5cm。 卡止凹槽太深安装比较费劲， 卡止凹 槽太浅二次限位诈 效果相对比较差。
在进一步优选的实施例中， 凸起的厚度小于卡止凹槽的深度。若凸起的厚度等于卡止凹槽 的深度， 为了安装面的平整， 凸起与卡止凹槽相互配合的面需要较高的平整度， 凸起的厚度小 于卡止凹槽的深度^, 对凸起与卡止凹槽相互配合面的平整度要求降低。
在一个实施倒中， 设有六个卡脚， 六个卡脚的宽度和占卡脚所在外圆圆周的 1/3〜1/2。 卡 脚具有较好的强度， 不容易折断或损坏。对所述卡脚的数量没有限制， 根据实际通风孔的孔洞 的直径而选定， 优选卡脚的数量为 3〜8个。 卡脚数量太多， 如多于 10个， 会增加加工难度和 加工成本。 卡脚数量太少， 如 2个卡脚， 容易出现受力不均衡。
在一个优选的实施例中， 六个卡脚的大小相等， 与卡脚配合的卡槽的大小相等。 不需要辨 别大小和方向， 安装方便。 險團说明
图 1所示是本发明的无尘车间地板通风孔及盖板组件中的盖板的一种实施例。
图 2所示是与图 1中的盖板配合的通风孔的结构示意图。 具体实旅方式
下面结合附图和具体实施倒对本发明作进一步说明。
如图 1和图 2所示是相互配合的用干无尘车间地板的通风孔 9及与该通风孔 9配合的盖板 10 的一种具体实施倒。 在该实施例中， 本发明的无尘车间地板通风孔及盖板组件包括若干个 设在无尘车间地板 8上的通风孔 9和与通风孔 9配合的盖板 10， 所述通风孔 9包括孔洞 7和 设在孔洞 Ί夕卜周的卡槽 5， 盖板 10包括盖体 i和设在盖体 i夕卜周的卡脚 3， 盖体 10与孔洞 7 相配合， 所述卡脚 3与卡槽 5相配合。
一般来说，根据无尘车间的洁净度要求以及气流流向的不同， 不同区域的盖体 1会要求有 不同的通风率。盖体 1根据不同的通风率要求设置有不同数量和 Z或直径不等的风孔 2, 当然若 不需要风孔 2 , 盖体 1上也可以没有风孔 2„
如图 2所示，在本实施例中， 优选若干个所述卡槽 5沿孔洞 7的周向均勾布置以使受力更 均勾。
一般为了加工方便， 卡槽 5为方形槽、 半圆形槽或弧形槽等相对规则的形状。 若千个卡槽 5可以是同 ·种形状， 也可以是其中有几个卡槽 5是一种形状， 另外的卡槽 5是其它形状这样 的组合方式。 在图 2中， 优选所述卡槽 5均为方形槽。
在一个优选的实施例中， 卡槽 5内设有卡止凹槽 6, 卡脚的安装面上设有与凹槽配合的凸 起 4， 安装 卡止凹槽 6与凸起 5配合起到限制盖板 10的周向转动。 在图 2中， 卡止凹槽 6 设在卡槽 5的中部。
ώ于通风孔的直径一般为 20〜50αη,在迸一步优选的实施例中， 为了能够更好的卡止盖板 10, 卡止凹槽 6比卡槽 5深 0,5〜2.5cm。 而且为了方便安装， 优选凸起 4的厚度小于卡止凹槽 6的深度。 此处， 凸起 4的厚度是指凸起 4突出卡脚 3的高度， 卡止凹槽 6的深度是指卡止凹 槽 6低于卡槽 5的表面的深度。 一般凸起 4的厚度比卡止凹槽 6的深度小 0.1cm〜0,4cm, 根据 实际情况来确定。
在本实施例，设有六个方形卡脚 3 ,六个卡脚 3的宽度和占卡脚 3所在外圆圆周的 1/3~1 /2。 在优选的实施例中， 六个卡脚 3的形状相同、 大小相等， 与卡脚 3配合的卡槽 5也是形状 相同、 大小相等。
虽然已经结合具体实施例对本发明进行了描述， 然而可以理解，在不] ¾离本发明的范围的 情况下， 可以对其迸行各种改进或替换。 尤其是， 只要不存在结构上的冲突， 各实施例中的特 征均可相互结合起来，所形成的组合式特征仍属于本发明的范围内。本发明并不局限于文中公 开的特定实施例， 而是包括落入权利要求的范围 ή的所有技术方案。
