Description
技术领域
本公开的实施例涉及存储系统,并且更具体地涉及用于机架的杆以及与机架配合使用的固定装置。
背景技术
在数据中心或存储系统中,通常需要将机器单元(例如,服务器、存储单元等)固定到机架上。然而,现有的固定装置在运输测试和/或震动测试中通常表现不佳,容易出现松动的情形。这在具体的使用中,可能导致数据丢失等严重问题,影响数据中心或存储系统的性能。
发明内容
为了解决本领域中存在的上述问题和其他潜在问题,在此提出一种用于机架的杆以及一种与机架配合使用的固定装置。
本公开的第一方面提供了一种用于机架的杆。该杆包括:第一端部,所述第一端部设有螺栓,所述螺栓具有梯形螺纹,在所述杆穿过目标设备被插入所述机架时,所述螺栓将所述第一端部连接到所述机架,从而将所述目标设备固定到机架。
在一些实施例中,杆包括第二端部,所述第二端部设有可手动旋转的手柄。由此,可以通过手动旋转手柄来旋转所述杆,从而将目标设备固定到所述机架上。
在一些实施例中,所述梯形螺纹符合爱克母螺纹规范。
在一些实施例中,杆还包括设置在所述第一端部的与所述螺栓配合使用的止挡件。
本公开的第二方面提供了一种与机架配合使用的固定装置。该固定装置包括:螺母,所述螺母具有梯形螺纹以用于接收杆,所述螺母适于与所述杆的端部的螺栓配合使用以通过所述杆将目标设备固定在所述机架上。
在一些实施例中,所述固定装置由塑料制成。
在一些实施例中,所述固定装置由塑料一体形成。
在一些实施例中,所述塑料包括聚碳酸酯和丙烯腈-丁二烯-苯乙烯共聚物或者玻纤增强聚碳酸酯。
在一些实施例中,所述梯形螺纹符合爱克母螺纹规范。
本公开的第三方面提供了一种机架,包括根据第二方面的固定装置。
由于采用了梯形螺纹,可以将目标设备更加牢固地固定到机架上,增强抗震性能,从而避免出现由于机械原因而出现的数据丢失问题。此外,由于固定装置可以使用塑料材质,在保证机械强度的前提下可进一步增强抗震性能,并且还可以显著减少制造成本。
附图说明
通过参考附图阅读下文的详细描述,本公开的上述以及其他目的、结构和特征将更加清楚。在附图中,以示例性而非限制性的方式示出了本公开的若干实施例,其中:
图1是根据本公开的实施例的应用环境的示意图;
图2是根据本公开的实施例的装配在一起的杆和对应的固定装置的示意图;
图3是如图2所示的杆的孤立的示意图;
图4是如图3所示的杆的其中一个端部的示意图;
图5a是根据本发明的实施例的螺纹的示意图;以及
图5b是根据现有技术的螺纹的示意图。
具体实施方式
下面将参考附图中示出的若干示例性实施例来描述本公开的原理和精神。应当理解,给出这些实施例仅仅是为了使本领域技术人员能够更好地理解进而实现本公开,而并非以任何方式限制本公开的范围。
图1示出了本公开的实施例的所涉及的应用环境100的示意图。如图1所示,机架1是数据中心或存储系统中常见的用于支撑和容纳机器单元2的装置。机器单元2例如可以是服务器、存储单元,等等。由于机器单元2需要被安装到机架上,因此机器单元2也可以被称为目标设备。在将机器单元2安装到机架1上时,杆4穿过机器单元2插入到机架1中,从而将机器单元2固定到机架1上。机架1上可以安装有与其配合使用的固定装置3,其可以与杆4配合使用以通过杆4将机器单元2固定在机架1上。
注意,尽管本公开的实施例将主要结合机架来加以描述,但是这仅仅是示例性而非限制性的。通过下文描述将会理解,在此描述的装置同样适用于其他设备和环境。
现在参考图2-4,详细描述固定装置3和杆4的结构和工作原理。为了简单起见,这些图中略去了机架和机器单元之类的有关装置。图2是杆4与固定装置3结合在一起的示意图,而图3单独地示出了杆4。如图2-3所示,杆4包括第一端部11和第二端部12。第一端部11在图4中进一步详细示出。
杆4的第一端部11设有螺栓6。在杆4穿过机器单元被插入机架时,螺栓6将第一端部11连接到机架,从而将机器单元固定到机架。为此,如图2所示,固定装置3包括螺母,螺母可以与杆4的第一端部11的螺栓6配合使用,从而通过杆4将机器单元2固定在机架1上。
此外,如图3-图4所示,在某些实施例中,杆4还可以包括设置在第一端部11的与螺栓6配合使用的止档件7。尽管图中示出了2个止档件,但是止档件7的数量同样可以是一个或三个以上。
如图2-图3所示,杆4还包括第二端部12,该第二端部12设有可手动旋转的手柄5。借助于手柄5,用户在操作中可以省去安装工具(例如螺丝刀)而方便地进行安装和拆卸。
图5a示出了根据本公开的实施例的截面形状(也称为螺纹牙形)为梯形的螺纹,即梯形螺纹。作为对比,图5b示出了根据现有技术的截面形状为三角形的螺纹,即三角螺纹。如图5a所示,外螺纹8和内螺纹9具有相应的梯形螺纹。如图5b所示,外螺纹8’和外螺纹9’具有相应的三角螺纹。内螺纹9和9’可以用于固定装置3的螺母,外螺纹8和8’可以用于杆4的螺栓。发明人制作了具有这两种类型的螺纹的杆4和固定装置3,并且对其进行了对比测试。在运输测试和震动测试中,已经证明:梯形螺纹具有显著优于三角螺纹的性能,机器单元不容易出现松动的情形,从而显著降低了由机械原因导致的数据丢失的可能性。与三角螺纹相比,梯形螺纹具有较多的角。也即,三角螺纹仅在端部包括一个角,而梯形螺纹在端部两侧包括两个角。这使得梯形螺纹能够具有优于三角螺纹的防震性能。
在一些实施例中,梯形螺纹可以符合爱克母(ACME)螺纹规范。作为示例,梯形螺纹可以是0.2500-16.0ACME-3G规格。当然,这仅仅是示例的,梯形螺纹可以根据任何目前已知或者将来开发的行业规范来设计和制造。
此外,在某些实施例中,固定装置3可以由塑料制成。由于塑料与金属材料性质的差异,塑料制成的固定装置3可以在保证机械强度的前提下带来更好的防震性能。此外,由于与金属相比塑料成本较低,由塑料制成的固定装置3还可以显著降低生产成本。
在一些实施例中,固定装置3可以由塑料一体形成,因而便于装配。作为示例,固定装置3可以注塑形成,并且塑料可以是聚碳酸酯和丙烯腈-丁二烯-苯乙烯共聚物(PC+ABS)或者玻纤增强聚碳酸酯(PC+玻纤)。
上文已经结合若干具体示例阐释了本公开的原理和精神。本公开的实施例可以将机器单元更加牢固地固定到机架上,增强抗震性能,从而避免出现由于机械原因而出现的数据丢失问题。此外,由于固定装置可以使用塑料材质,因而进一步增强抗震性能,并且还可以显著减少制造成本。请注意,上文结合附图描述的各个实施例之间不是互斥的。相反,结合这些实施例描述的特征可以根据实际情况而任意排列和组合。本公开的范围在此方面不受限制。
虽然已经参考若干具体实施例描述了本公开,但是应该理解,本公开并不限于所公开的具体实施例。本公开旨在涵盖所附权利要求的精神和范围内所包括的各种修改和等同布置。所附权利要求的范围符合最宽泛的解释,从而包含所有这样的修改及等效结构。
