Description

一种进水阀高度调节机构 技术领域
本发明涉及进水阀技术领域，尤其是指一种进水阀高度调节机构。
背景技术
现有技术中，进水阀通常包括进水管、进水阀主体、控制阀、控制杆、浮桶和浮箱，进水管进水端安装在冲水箱的供水管上，进水管为冲水箱供水，进水管套接在进水阀主体中，进水阀主体中设置控制阀并通过控制阀控制水流通断，而控制阀的闭合通过控制杆动作实现；控制杆与浮桶连接，浮桶置于浮箱中，浮箱安装在进水阀主体上。
浮箱水位下降时，浮桶受重力作用随之下降，带动控制杆动作打开控制阀，水从供水管流经进水管，然后经进水阀主体进入冲水箱中，实现进水。浮箱水位上升时，浮桶受浮力作用随之上升，带动控制杆动作关闭控制阀，停止进水。
进水阀安装于冲水箱时，由于冲水箱的型号不同，需要调节进水阀安装高度。现有技术中，进水阀高度调节机构各异，有的在进水管主体外侧壁上沿轴向设置多排间隔卡齿，进水阀主体内侧壁对应设置卡齿，进水管套接在进水阀主体中，转动进水阀主体使两卡齿啮合定位，拆卸时，转动进水阀主体使两卡齿松脱，其缺陷在于，在转动进水阀主体时，容易使进水管进水端安与冲水箱的供水管的连接松脱，造成漏水，或者需要手伸入冲水箱中稳定进水管，调节不方便。
或者，如公告号为CN202689138U公开的进水阀高度调节机构，其在进水管设置外齿，进水管套接在进水阀主体中，进水管和进水阀主体套接处设置卡圈，卡圈的内壁设有与外齿相匹配卡合的内齿，在进水阀主体上外壁设置可上下移动的调节杆，调节杆与卡圈联动使卡圈旋转，实现卡圈的内齿旋入或旋出进水管的外齿。其缺陷在于：所述进水阀高度调节机构调节进水阀高度时，卡圈转动不顺畅，调节依然不方便。
发明内容
本发明的目的在于提供一种进水阀高度调节机构，以实现快速调节高度，快速安装和拆卸，且高度调节较为方便。
为达成上述目的，本发明的解决方案为：
一种进水阀高度调节机构，包括进水管、进水阀主体和调节固定套；进水阀主体下端设置轴向剖槽，进水阀主体设置剖槽的内壁上沿圆周方向设置卡槽；进水管的外壁上沿圆周方向设置凸起卡齿，进水管套接在进水阀主体中，进水管的卡齿卡入进水阀主体的卡槽中；调节固定套活动套接在进水阀主体设置剖槽的下端外壁上，调节固定套与进水阀主体紧配合。
进一步，在调节固定套上安装有复位弹簧。
进一步，还包括套管，套管套接在进水阀主体外壁上，且进水阀主体下端伸出于套管外，复位弹簧一端抵靠在调节固定套上，复位弹簧另一端抵靠在套管上。
进一步，进水阀主体下端端部外侧壁上设置限位凸条，调节固定套抵靠在限位凸条上，调节固定套轴向向上延伸形成连接部，连接部上端径向延伸形成承载部，承载部轴向向上延伸形成限位部；套管外壁上形成轴向滑槽，调节固定套的连接部在轴向滑槽中滑行；复位弹簧一端抵靠在调节固定套的承载部上，复位弹簧另一端抵靠在套管径向延伸的凸缘上。
进一步，进水管外壁的卡齿为螺纹齿。
进一步，该螺纹齿沿进水管的外壁由一端延伸至另一端。
进一步，进水阀主体内壁下端设置多个轴向凸筋，卡槽设置在该多个轴向凸筋上。
进一步，进水管外壁上设置轴向筋条，该轴向筋条置于进水阀主体的相邻两轴向凸筋之间，且轴向筋条的宽度小于两轴向凸筋之间的宽度。
进一步，进水管外壁的卡齿为平行齿。
进一步，该平行齿沿进水管的外壁由一端延伸至另一端。
采用上述方案后，本发明在安装时，进水管进水端安装在冲水箱的供水管上，进水管套接在进水阀主体中，进水管的卡齿卡入进水阀主体的卡槽中，并将进水阀主体调节至合适高度，然后将调节固定套套接在进水阀主体下端外壁上，调节固定套与进水阀主体紧配合，此时由于调节固定套的限制，进水阀主体下端设置剖槽处无法产生径向弹性变形，使得进水管的卡齿紧紧卡在进水阀主体的卡槽中而定位。
需要重新调节进水阀主体高度或者拆卸进水阀主体时，滑动调节固定套使其离开进水阀主体下端设置剖槽处，解除调节固定套对进水阀主体下端设置剖槽处径向弹性变形限制，使得进水阀主体下端可以向外产生变形，可以将进水管外壁的凸起卡齿从进水阀主体内壁的卡槽中拔出，重新调整进水阀主体的高度或者将其拆卸。
因此，本发明可以实现快速调节高度，快速安装和拆卸，且高度调节较为方便。

具体实施方式
以下结合附图及具体实施例对本发明做详细描述。
参阅图1至图7所示，本发明揭示的一种进水阀高度调节机构实施例一，包括进水管1、进水阀主体2和调节固定套3。
进水阀主体2下端设置轴向剖槽21，剖槽21的个数可以任意，设置剖槽21的目的在于增加弹性，进水阀主体2设置剖槽21的内壁上沿圆周方向设置卡槽22，如图6及图7所示。
进水管1的外壁上沿圆周方向设置凸起卡齿11，进水管1套接在进水阀主体2中，进水管1的卡齿11卡入进水阀主体2的卡槽22中。本实施例中，进水管1外壁的卡齿11为螺纹齿，该螺纹齿沿进水管1的外壁由一端延伸至另一端。对应地，进水阀主体2内壁下端设置多个轴向凸筋23，卡槽22设置在该多个轴向凸筋23上。
进水管1外壁上设置轴向筋条12，该轴向筋条12置于进水阀主体2的相邻两轴向凸筋23之间，且轴向筋条12的宽度小于两轴向凸筋23之间的宽度，使得在调整进水阀主体2的高度时，进水阀主体2可以回调两轴向凸筋23之间的宽度与轴向筋条12的宽度差值，从而达到更为精准的调节。
调节固定套3活动套接在进水阀主体2设置剖槽21的下端外壁上，调节固定套3与进水阀主体2紧配合，所述紧配合是指当进水阀主体2下端受到径向向外的力时，调节固定套3给与进水阀主体2下端一反向力。
在调节固定套3上安装有复位弹簧4。本实施例中，复位弹簧4的安装方式为：进水阀主体2外壁上套接套管5，且进水阀主体2下端伸出于套管5外，复位弹簧4一端抵靠在调节固定套3上，复位弹簧4另一端抵靠在套管5上。
进水阀主体2下端端部外侧壁上设置限位凸条24，如图6及图7所示，调节固定套3抵靠在限位凸条24上，调节固定套3轴向向上延伸形成连接部31，连接部31上端径向延伸形成承载部32，承载部32轴向向上延伸形成限位部33。套管5外壁上形成轴向滑槽51，调节固定套3的连接部31在轴向滑槽51中滑行。复位弹簧4一端抵靠在调节固定套3的承载部32上，复位弹簧4另一端抵靠在套管5径向延伸的凸缘52上。
安装时，进水管1进水端安装在冲水箱的供水管上，进水管1套接在进水阀主体2中，进水管1的卡齿11卡入进水阀主体2的卡槽22中，将进水阀主体2调节至合适高度，然后将调节固定套3套接在进水阀主体2下端外壁上，调节固定套3与进水阀主体2紧配合，由于调节固定套3的限制，进水阀主体2下端设置剖槽21处无法产生径向弹性变形，使得进水管1的卡齿11紧紧卡在进水阀主体2的卡槽22中而定位。
需要重新调节进水阀主体2高度或者拆卸进水阀主体2时，向下拨动调节固定套3的限位部33，拉伸复位弹簧4，从而滑动调节固定套3使其离开进水阀主体2下端设置剖槽21处，解除调节固定套3对进水阀主体2下端径向弹性变形限制，使得进水阀主体2下端可以向外产生变形，可以将进水管1外壁的凸起卡齿11从进水阀主体2内壁的卡槽22中拔出，重新调整进水阀主体2的高度或者将其拆卸，在重新调整好进水阀主体2的高度后，固定套3在复位弹簧4的作用下重新套接在进水阀主体2下端设置剖槽21处，重新定位。
参阅图8至图13所示，本发明揭示的一种进水阀高度调节机构实施例二，与实施例一的不同之处在于：本实施例中，进水管1外壁的卡齿11为平行齿，该平行齿沿进水管1的外壁由一端延伸至另一端，进水阀主体2下端设置剖槽21处设置与平行齿匹配的卡槽22。
以上所述仅为本发明的优选实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
