Description

密接式车钩用风管连接器及密接式车钩用风管连接器组件 技术领域
本发明涉及一种车辆风管连接器，尤其是用于实现密接式车钩主风管和解钩管自动连接的风管连接器及其组件。
背景技术
为提高动车组、地铁车辆的乘坐舒适性，减小各车厢间车钩的纵向冲击力，目前高速动车组、地铁车辆的车厢端部连接普遍采用密接式车钩缓冲装置。密接式车钩缓冲装置分为全自动、半自动及半永久车钩缓冲装置，其中全自动和半自动车钩缓冲装置要求在机械车钩连挂的同时实现风管的连接，且解钩后能够实现主风管自动锁闭，防止漏风。
其中，风管连接器主要用于实现密接式车钩主风管和解钩管的自动连接及主风管的自动锁闭。作为示例，图1提供了一种现有技术中的风管连接器组件，其主要由阀口橡胶01、阀头02、橡胶管03、压力弹簧04、解钩管05、阀体06、密封垫07、挺杆弹簧08、主风管09及挺杆010等组成，该风管连接器组件可以实现：车钩连挂时主风管和解钩管的自动导通及车钩解钩时主风管的自动锁闭。但一方面，主风管连接器内部的密封结构由橡胶管03、压力弹簧04与阀头02、阀体06相互挤压组成；另一方面，解钩风管连接器的密封结构由通过橡胶材料制成的解钩管05与阀体06的相互挤压来形成，并通过套设在其外周的弹簧来实现其回弹效果。这两处的密封结构中使用的橡胶管成型复杂，制造技术难度高，且零件通用性不强，用户使用维护不方便；此外，在阀头和阀体之间采用的这种既具有一定弹性又具有较高强度的橡胶管，在实际使用中的密封效果并不理想，这两处的密封结构中使用的橡胶管因暴露在外，容易老化，使用寿命短。

以下将结合附图给出的实施例对本发明作进一步详细的说明。

具体实施方式
参见图2，其示出本发明的一个实施例的密接式车钩用风管连接器组件。其中，密接式车钩用风管连接器包括：阀体6、阀头2、挺杆8、第一弹性元件5、第一阀口密封元件1及挺杆密封元件7。
具体而言，阀体6包括位于上部的阀孔座6-1及置于阀孔座6-1下部的解钩管连接部；其中，阀孔座6-1内设有阀孔6-3，且解钩管连接部设有解钩管孔6-2。而阀头2则具有朝阀体6方向延伸的筒体2-1，筒体2-1套装在阀孔座6-1上且与阀孔座6-1滑动配合，并相对于阀孔座6-1密封。再者，挺杆8的杆身与阀体6的阀孔6-3滑动配合。此外，第一弹性元件5套装在筒体2-1外，并部分地套装在阀孔座6-1外，且其一端与阀头2相抵，另一端与阀体6相抵；而第一阀口密封元件1安装在阀头2背离阀体6方向的一端；挺杆密封元件7装在挺杆8的杆头上，且与阀孔6-3的孔口通断配合。由此实现了一种简单、可靠的密封方式，并省却了现有技术中因暴露在外而致使易于老化的橡胶管结构。
根据图2中未示出的本发明的另一实施例，第一弹性元件5还可直接套装在阀孔座(6-1)外，且使其一端与阀头(2)的筒体(2-1)相抵，另一端与阀体(6)相抵。如此同样可以实现在阀头(2)朝向阀体(6)运动时，压缩第一弹性元件5并使之储能，且在阀头(2)背离阀体(6)运动时提供回弹力。
优选地，为进一步确保筒体2-1与阀孔座6-1之间的密封性，可在筒体2-1与阀孔座6-1之间设置第一密封圈3。此种密封方式有效避免了第一密封圈3暴露于空气中，进而消除了此类密封结构因氧化而导致的易于老化的问题，提高了密封性能及密封元件的使用寿命。
再者，对于本发明中提及的弹性元件或密封元件，本发明进一步地提供若干实施方式，其具有易于加工、易于装配且性能稳定等效果。例如，第一弹性元件5可为压力弹簧，该压力弹簧套设在筒体2-1外，且一端与阀头2相抵，另一端与阀体6相抵，并随着阀头2与阀体6之间的相对运动而压缩或回弹。挺杆密封元件7可为挺杆密封垫，该挺杆密封垫可套装在挺杆8的杆头处。具体而言，其可在杆头处朝向阀体6的一侧设置凹槽，将挺杆密封垫嵌入该凹槽中，使得挺杆8与阀体6发生相对运动时密封两者间的间隙或释放开两者的间隙。第一阀口密封元件1则可为阀口橡胶，以在相对的两个密接式车钩用风管连接器对接时提供缓冲与密封。
另外，参见图6及图7，其示出了本发明的阀头的一个实施例详细结构。其中，可在筒体2-1的内壁开设两道环槽2-3，筒体2-1与阀孔座6-1之间装有第一密封圈3，第一密封圈3置于环槽2-3中且其内圈与阀孔座6-1的外周相接触。此处所示的环槽数目仅出于示例性目的。当所需的密封要求相对较低时，采用一道环槽2-3与一道第一密封圈3配合亦可。而当密封要求十分严苛时，也可采用更多环槽2-3与更多第一密封圈3配合。
另外，阀头2在背离筒体2-1的一端还设有止挡件2-2，其在阀头2安装至车钩4上时提供限位作用。
根据本发明的另一个实施例，还提供一种密接式车钩用风管连接器组件。除去密接式车钩用风管连接器外，图2所示的密接式车钩用风管连接器组件还包括：主风管11、第二弹性元件9、解钩管14及解钩管弹性元件12。
具体而言，主风管11固连在阀体6远离阀头2的一端。第二弹性元件9设于其间，其一端与挺杆8的杆头相抵，而另一端与主风管11相抵，用于在主风管11与挺杆8之间发生相对运动时压缩或回弹。解钩管14则插设在阀体6下部的解钩管连接部中的解钩管孔6-2内，并 与其滑动密封配合。解钩管弹性元件12设于解钩管孔6-2内，其一端与解钩管14的后端面相抵，另一端与解钩管孔6-2的底部的阀体(6)内壁相抵，也用于在解钩管14与解钩管孔6-2的底部之间发生相对运动时压缩或回弹。
可选地，为加强装置的密封性，本发明还在多处设置密封圈及安置密封圈的沟槽。也可在主风管11与阀体6之间设置第二密封圈10。还可在解钩管14的外周与解钩管孔6-2的内壁之间设置第三密封圈13。第三密封圈13置于解钩管14的外周的密封槽中。作为一种实施方式，本文所述的第一密封圈3、第二密封圈10及第三密封圈13均可采用O型密封圈的结构形式。
可选地，为加强装置的密封性，解钩管14的前端设置第二阀口密封元件15，其可在不同解钩管14对接时提供缓冲与密封。
同样地，对于本发明中提及的弹性元件或密封元件，本发明也进一步地提供若干实施方式，其具有易于加工、易于装配且性能稳定等效果。例如，第二弹性元件9为挺杆弹簧。又如，解钩管弹性元件12为解钩管弹簧；并在解钩管14的后端面设置沉孔14-1，解钩管弹性元件12的一端插设在沉孔14-1中。再如，第二阀口密封元件15为阀口橡胶。
参见图3、4，其示出将本发明的密接式车钩用风管连接器组件通过螺栓16安装至车钩4的端面上。
并参见图5，其示出本发明的密接式车钩用风管连接器组件的连挂导通状态。此时，两个车钩4上的密接式车钩用风管连接器组件的第一阀口密封元件1、第二阀口密封元件15相互接触，并在第一弹性元件5和解钩管弹性元件12的作用下压紧密封，此时两个车钩的主风管11自动连接，同时两个车钩的解钩管14亦自动连接。由于第一弹性元件5的压缩使得两个密接式车钩用风管连接器的挺杆8接触并背离阀头2移动，挺杆8因而促使置于杆头处的挺杆密封元件7与阀体6分离，进而通过两个密接式车钩用风管连接器实现主风管11的自动导通。此时，第一弹性元件5、第二弹性元件9及解钩管弹性元件12均受到压力，处于压缩状态。
此外，在图5未示出的本发明的密接式车钩用风管连接器组件的 解钩状态下，第一阀口密封元件1、阀头2、第二阀口密封元件15及解钩管14不再受到挤压密封，同时随着车钩4的分离而断开连接；并且挺杆8之间也不再相互接触。此时，阀头2在第一弹性元件5的回弹力的作用下复位；挺杆8在第二弹性元件9的回弹力的作用下复位，并促动挺杆密封元件7与阀体6接触，在风压和第二弹性元件9的作用下，阀体6和挺杆密封元件7相互挤压密封，实现自动锁闭。且解钩管14在解钩管弹性元件12的回弹力的作用下复位。
在本发明的描述中，需要理解的是，“上”、“下”、“前”、“后”、“左”、“右”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或特征必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
以上例子主要说明了本发明的密接式车钩用风管连接器及其组件的结构及工作方式。尽管只对其中一些本发明的实施方式进行了描述，但是本领域普通技术人员应当了解，本发明可以在不偏离其主旨与范围内以许多其他的形式实施。因此，所展示的例子与实施方式被视为示意性的而非限制性的，在不脱离如所附各权利要求所定义的本发明精神及范围的情况下，本发明可能涵盖各种的修改与替换。
