具体实施方式
在相关技术的方案中，空调在出厂前需要对制冷管路的振动幅度进行检测，以保证后续的使用安全性。制冷管路的振动幅度的检测一般需要委托专门的检测机构进行，空调器生产厂商需要根据检测结果对制冷管路进行调整，直至制冷管路的振动幅度复合相关要求。但是，这样一来需要将待检测的产品运送到检测机构，检测完成后还需要再运回来，整个检测流程较复杂，耗费时间长；并且检测过程中耗费的人力物力也较多，费用较高，增加了生产成本。
有鉴于此，本申请旨在提供一种管路振动测试装置，通过闪频测速仪观察制冷管路的振动方向，然后通过测量装置测量出制冷管路的振动幅度。利用本申请的管路振动测试装置对制冷管路的振动幅度进行预检测，若发现制冷管路的振动幅度不符合要求可及时对制冷管路进行调整，然后再将调整后的制冷管路送到专门的检测机构进行振动幅度的检测，从而能够提高检测的成功率，降低返检率，有利于缩短检测时间，降低检测成本。

请参照图1-图3，本实施例提供了一种管路振动测试装置，包括：闪频测速仪10，闪频测速仪10具有沿第一方向X设置的光出口。闪频测速仪10是利用视觉暂留现象而制做的测量仪器(当以设定频率闪动的光源与物体的振动幅度同步时，会产生相对静止的视觉暂留现象)。在用于观测高速运动的物体时，通过调节它的闪动频率使其与被测物体的运动速度接近并同步，此时被测物虽然在高速运动着，但看上去却是缓慢运动或静止的，使人用肉眼就能很容易的观测高速运动物体的运动状况。本实施例的闪频测速仪10上设有旋钮11和电源接口12，使用时将电源接口12与电源进行接通，通过调节旋钮11来调节光出口射出的光线的频率，使得光线频率接近制冷管路的振动频率，从而可以通过闪频测速仪10观察制冷管路的振动方向。
连接件20，沿第一方向X，连接件20的第一端与闪频测速仪10固定连接，且连接件20的第一端围绕在光出口的外侧，连接件20的内部形成有空腔，连接件20还设有开口，开口与光出口相对设置。本实施例的连接件20主要起到连接闪频测速仪10和测量装置30的作用，并且为闪频测速仪10提供光线通过的通道。
测量装置30，测量装置30固定设置在连接件20的第二端，测量装置30上设有刻度线。
本实施例在使用时，闪频测速仪10射出的光线可以通过连接件20内的空腔后到达制冷管路，工作人员可以通过闪频测速仪10观察到制 冷管路的振动方向，然后利用测量装置30测量出制冷管路的振动范围，并根据振动范围得到制冷管路的具体振动幅度，然后与标准振动幅度进行比较，从而判断制冷管路的振动幅度是否符合要求。
利用本实施例的管路振动测试装置，可以在出厂前对制冷管路的振动幅度进行预检测，若发现制冷管路的振动幅度不符合要求可及时对制冷管路进行调整，然后再将调整后复合要求的制冷管路送到专门的检测机构进行振动幅度的检测，从而能够提高检测的成功率，降低返检率，有利于缩短检测时间，降低检测成本。
可选地，如图1和图2所示，本实施例的连接件20包括本体21、第一连接部22和第二连接部23，本体21的两端分别连接第一连接部22和第二连接部23，第一连接部22设置在连接件20的第一端，第二连接部23设置在连接件20的第二端。第一连接部22套设在闪频测速仪10的外侧，第二连接部23抵接测量装置30。
进一步地，如图3所示，本体21包括顶壁211、底壁212以及连接顶壁211和底壁212的第一侧壁213和第二侧壁214，顶壁211、底壁212、第一侧壁213和第二侧壁214可以首位依次相连接，并通过焊接的方式固定。沿第一方向X，第一侧壁213的长度等于第二侧壁214的长度，顶壁211的长度小于第一侧壁213的长度，底壁212的长度大于第一侧壁213的长度；顶壁211、底壁212、第一侧壁213和第二侧壁214共同围成空腔，开口形成在空腔背离闪频测速仪10的一端。
第一连接部22为连接顶壁211、底壁212、第一侧壁213和第二侧壁214的棱台，在本实施例中第一连接部呈四棱台状，第一连接部22可以焊接固定在本体21上。
第二连接部23包括支撑板231和限位槽232，支撑板231设置在第一侧壁213背离第二侧壁214的一侧，支撑板231通过连接板固定在底壁212上，支撑板231沿第二方向Y延伸；支撑板231可以焊接固定在 连接板上，连接板可以与底壁212焊接固定。限位槽232设置在第二侧壁214的一侧，限位槽232固定连接在底壁212上，例如可以采用焊接连接的方式固定在底壁212上，限位槽232的槽口朝向第一侧壁213。
在本实施例中，第一方向X与第二方向Y垂直。
在垂直于第一方向X的截面内，本实施例的闪频测速仪10的投影呈方形，第一连接部22的投影也呈方形，且第一连接部22的投影覆盖闪频测速仪10的投影，从而使得第一连接部22能够套设在闪频测速仪10的外侧。
优选地，本实施例中，第一连接部22与闪频测速仪10可以通过卡接或粘接等连接方式连接固定。
可选地，本实施例的测量装置30沿第二方向Y延伸，测量装置30上的刻度线也沿第二方向Y设置，从而便于对制冷管路进行测量。测量装置30的部分搭接在支撑板231上，测量装置30的第一端卡设在限位槽232内，通过上述方式实现对测量装置30的支撑固定。
进一步地，本实施例的支撑板231背离第一侧壁213的一端还设有两个限位凸起233，两个限位凸起233沿第一方向X相对设置，测量装置30的第二端位于两个限位凸起233之间，从而可以利用两个限位凸起233对测量装置30的第二端进行限位，进一步防止测量装置30在测量的过程中发生移动。
在一个可能的实施方式中，本实施例的测量装置30为游标卡尺，游标卡尺的外测量爪31设置在背离闪频测速仪10的一侧，测量时将制冷管路放置于两个外测量爪31之间，两个外测量爪31的张开幅度与制冷管路的振动范围相同，从而可以读取到制冷管路的振动范围，进而得到制冷管路的振动幅度。
在另一个可能的实施方式中，测量装置30还可以为刻度尺，刻度尺的刻度线设置在背离闪频测速仪10的一侧，此时可以通过闪频测速 仪10进行观察，读取制冷管路的振动范围在刻度尺上的相应刻度，进而得到冷管路的振动幅度。
可选地，本实施例的第一侧壁213背离底壁212的一侧设有第一导向面2131，第二侧壁214背离底壁212的一侧设有第二导向面2141；沿背离闪频测速仪10的方向，第一导向面2131和第二导向面2141均朝向底壁212倾斜。
通过上述描述可知，本申请可以通过闪频测速仪10观察制冷管路的振动方向，然后通过测量装置30测量出制冷管路的振动幅度。在出厂前可利用本申请的管路振动测试装置对制冷管路的振动幅度进行预检测，若发现制冷管路的振动幅度不符合要求可及时对制冷管路进行调整，然后再将调整后复合要求的制冷管路送到专门的检测机构进行振动幅度的检测，从而能够提高检测的成功率，降低返检率，有利于缩短检测时间，降低检测成本。
