双拉线操纵手把及汽油机
相关申请的交叉引用
本公开要求于2017年04月29日提交中国专利局的申请号为2017102978169、名称为“双拉线操纵手把”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及汽油机控制领域，具体而言，涉及一种双拉线操纵手把及汽油机。
背景技术
背负式吹风机、背负式喷雾喷粉机等便携式工具通常以汽油机为配套动力带动叶轮等执行部件运动，以此达到清扫、喷雾等作业，操纵手把作为重要控制部件，用于汽油机的启动、停车及转速变化。
随着人们对环境保护的重视以及各国家对汽油机排放数值的限制，越来越多的二冲程汽油机通过在消音器内部增加触媒的方式来降低排放，该方式的优点是简单易行，缺点是触媒的增加导致消音器过热。
如操纵手把的停车仍通过电路阻断火花塞点火的方式停车，停车后的瞬间在惯性的作用下，活塞继续运动、新鲜的混合气仍可以通过化油器、缸体直接进入高温的消音器而爆燃，产生放炮、排气口喷火现象。

停车手柄2滑动安装在左壳体4的边缘处设有的卡槽21上，停车手柄2设有的插口36，供弹簧片13插入，弹簧片13圆弧的凸起侧与定位轴15紧贴在一起，手推柄38位于手把壳体的外侧，供手指推动，停车手柄2设有的挂钩孔12配置成放置停车拉线8的停车拉线挂钩19。
自锁手柄3由上臂钩16和锁柄32通过凸起44、第二凹槽43耦合形成的，耦合处形成含锁定孔31的套管30，上臂钩16上设有拉钩29，拉钩29与油门操纵手柄11的第一凹槽22相配合，套管30外套有一自锁扭簧18，锁定孔31放入左壳体4内侧的锁定轴17上，锁柄32位于手把壳体的外侧，自锁手柄3转动安装在左壳体4内。
当然了，通过凹凸结构相互吻合形成套管30的方式可以为，上臂钩16设置有凸起44，锁柄32设置有第二凹槽43；上臂钩16设置有第二凹槽43，锁柄32设置有凸起44；或者各自均设置有凸起44和第二凹槽43，相互配合即可。
油门限位手柄1通过螺钉轴10穿过左壳体4的通孔39转动安装在手把壳体的左壳体4的外侧，在左壳体4的内侧装有防脱螺母27，油门限位手柄1设有的拨叉20经左壳体4的扇形通孔33穿出。
油门操纵手柄11设有的螺钉套管40套装在螺钉轴10上转动，一端设有第一凹槽22和油门挂钩孔23，油门挂钩孔23配置成钩挂油门拉线挂钩24，油门操纵手柄11的另一面设有挡块28，与拨叉20配合。油门操纵手柄11还设有挡板25，螺钉套管40上装有复位扭簧14，复位扭簧14的一端靠在挡板25上，另一端插入左壳体4内侧的插孔37内。
油门限位手柄1与油门操纵手柄11均能绕螺钉轴10同轴转动。
停车拉线8设有的停车拉线挂钩19钩挂在挂钩孔12内，外套有停车线护套34，另一端连接汽油机进气通道的阀门；
油门拉线9设有的油门拉线挂钩24钩挂在油门挂钩孔23内，外套有油门线护套35，另一端连接汽 油机化油器的油门。
停车线护套34、油门线护套35分别放置在左壳体4内并排设置的停车线护槽41和油门线护槽42内。
由自攻螺丝6将左壳体4与右壳体5紧固在一起形成完整的手把。
具体工作过程：
结合图3，(一)机构处于“怠速”状态：
用拇指向上推动手推柄38，即可使定位轴15位于弹簧片13的“开”的位置，停车手柄2连接的停车拉线8使汽油机进气通道阀门完全打开，连接在油门拉线9的汽油机油门处于低供油状态，此时启动机器后汽油机处于怠速状态低速运行，在自锁扭簧18的作用下，上臂钩16的拉钩29钩住油门操纵手柄11的第一凹槽22，使油门操纵手柄11处于被锁定的状态，以此防止油门操纵手柄11被意外触动后带来的安全隐患；此时油门限位手柄1也不能转动。
结合图4，(二)机构处于“高速”状态：
用手扳动自锁手柄3，拉钩29将随之转动并远离第一凹槽22，油门操纵手柄11将不被锁定而处于释放状态，此时用食指扳动油门操纵手柄11，连接油门拉线9的汽油机油门开度将随之变大，汽油机将逐渐处于高速状态，此时，油门操纵手柄11处于释放状态，当油门操纵手柄11处于最大位置时，汽油机油门开度最大，机器处于高速状态，转动油门限位手柄1，通过拨叉20将油门操纵手柄11限定在该位置；转动油门操纵手柄11使其处于任意位置时，转动油门限位手柄1，可实现将油门操纵手柄11限定在任意位置。
结合图5，(三)机构处于“停车”状态：
无论机器处于高速状态或其它任意转速状态，当用拇指向下推动手推柄38，使定位轴15位于弹簧片13的“关”的位置，即可带动停车拉线8运动，此时连接在停车拉线8上的汽油机进气通道阀门将立即关闭，阻断汽油机混合气的进入，使汽油机立即停止运转，机器处于停车状态。
根据上述的双拉线操纵手把，其具有至少以下优点：
由于操纵手把内安装两根拉线，在单手握住操纵手把的情况下既可通过停车手柄2和油门操纵手柄11控制汽油机进气通道阀门和油门，避免了必须通过双手操纵停车装置和油门操纵手把带来的不便；同时该双拉线操纵手把还具有油门自锁功能，进一步杜绝了误加油门带来的危害；机器处于某一转速长时间运行时，可通过油门限位手柄1将油门操纵手柄11限制在任一特定位置，不需要长期手持操作，大大减轻了劳动强度，提高了人性化操纵。
该双拉线操纵手把还具有油门自锁功能和油门限位功能。
油门自锁功能：当汽油机处于怠速运行状态时，为防止意外触动油门操纵手柄11使汽油机转速突然升高带来的安全隐患，自锁手柄3将油门操纵手柄11锁定在怠速状态，此时只有先触动自锁手柄3后才可以启动油门操纵手柄11。
油门限位功能：根据需要，机器处于某一转速长时间运行时，可通过油门限位手柄11将油门操纵手柄11限制在任一特定位置，不需要长期手持操作，大大减轻了劳动强度，因此该双拉线操纵手把不仅通过单手可以控制汽油机进气通道及汽油机进油量，即控制汽油机的停车和转速变化，还为操作者在使用上提供了人性化和安全性的保障。
结合图1-图20，本公开的实施例还提供了一种双拉线操纵手把，其包括手把壳体、油门操纵手柄11、自锁手柄3和停车手柄2；

可选的，停车手柄2包括相互连接的手推柄38和弹簧片13，手推柄38位于卡槽21外，弹簧片13位于卡槽21内，手把壳体内设置有定位轴15，弹簧片13紧贴定位轴15，弹簧片13设置有两个凹陷区，以使停车手柄2在起动位置或停车位置上时，定位轴15位于其中一个凹陷区内。
结合图12，可以理解的，手推柄38设置有两个插口36，弹簧片13的两端卡入对应的两个插口36 后实现与手推柄38相对固定，弹簧片13的两个凹陷区更好的将定位轴15进行容置，使用时，首先克服弹簧片13的弹性作用力，然后推动手推柄38移动，若此时将定位轴15从一个凹陷区转移至另一个凹陷区，则在弹簧片13的作用力下，手推柄38不容易脱离。两个凹陷区则分别对应了起动位置和停车位置。
可选的，弹簧片13呈圆弧状，圆弧的凸起44侧与定位轴15相接触。
呈圆弧状的弹簧片13，能够产生较大的作用力，类似于弓的原理。

可选的，双拉线操纵手把还包括自锁扭簧18，自锁扭簧18与套管30连接，自锁扭簧18令拉钩29具有靠近第一凹槽22的运动趋势。
也就是说，在自锁扭簧18的作用下，可以实现拉钩29较为稳定的钩住第一凹槽22。
可选的，双拉线操纵手把还包括油门限位手柄1，油门限位手柄1可转动的连接于手把壳体，油门限位手柄1设置有拨叉20，油门操纵手柄11设置有挡块28，拨叉20与挡块28配合。

结合图2，油门操纵手柄11可转动的连接在手把壳体上，其配置成控制汽油机的油门开度，螺钉轴10从外向内穿过手把壳体，油门限位手柄1和油门操纵手柄11绕螺钉轴10同轴转动。
图2中的相对位置中，油门操纵手柄11、油门限位手柄1位于左侧，停车手柄2、自锁手柄3位于右侧。一般的，使用时，右手握住手把壳体，手心抵住自锁手柄3，拇指用来推动停车手柄2使其滑动，食指作用在油门操纵手柄11上，拇指或者另一只手可以作用在油门限位手柄1上，这种结构符合人体力学的设计，较为人性化。

自锁手柄3的转动连接处安装有自锁扭簧18，其使拉钩29具有钩住第一凹槽22的运动趋势，提高锁死效果。
油门操纵手柄11设置的油门挂钩孔23，其配置成使油门拉线9端部的油门拉线9拉钩29挂住，实现对油门拉线9的控制。油门操纵手柄11的转动连接处还安装有复位扭簧14，按下油门操纵手柄11，油门开度变大，松开后，在复位扭簧14的作用下，使油门操纵手柄11复位，从而使油门开度变小。
停车手柄2滑动连接在手把壳体上，其一部分位于手把壳体的卡槽21的外部，一部分位于卡槽21的内部。停车手柄2包括相互连接的手推柄38和弹簧片13，手推柄38位于卡槽21的外部，弹簧片13位于卡槽21的内部并且其与位于手把壳体内的定位轴15相抵。弹簧片13具有两个凹陷区(可以理解为起动位置和停车位置)，停车手柄2的端部设置有挂钩孔12，其配置成使停车拉线8端部的停车拉线挂钩19挂住。停车拉线8的另一个端部用于控制汽油机的进气通道的阀门。
弹簧片13自带的弹性作用力，可以使定位轴15与起动位置和停车位置相对固定。
手把壳体内设置的挡柱26与自锁扭簧18的一端相抵。
图3中，拉钩29卡在第一凹槽22内，使油门操纵手柄11处于自锁状态，此时，油门的开度较小，当停车手柄2位于起动位置时，在汽油机的进气通道的阀门的控制下，进气通道完全打开，若汽油机起动，则其处于怠速状态。
结合图4，图4中的结构和图3中的结构相同，不同之处在于，图4中的拉钩29脱离第一凹槽22，油门操纵手柄11处于释放状态，其可以自由转动，因此可以通过转动，拉动油门拉线9，从而使汽油机处于不同的运行速度下。通过转动油门限位手柄1，拨叉20可以将油门操纵手柄11限定在所处位置。
结合图5，图5中的结构和图4中的结构相同，不同之处在于，无论油门操纵手柄11处于哪种状态下，只要推动停车手柄2，使其控制的停车拉线8控制该阀门关闭，便可以阻断汽油机混合气进入，使汽油机立即停止，及其处于停车状态。一般的，停车后，操作自锁手柄3，使油门操纵手柄11处于自锁状态，从而可以在一定程度上提高安全性。
结合图6，拨叉20与挡块28配合，从而实现油门限位手柄1限制油门操纵手柄11。螺钉轴10穿过左壳体4，进入手把壳体的内部，在左壳体4的内部安装的防脱螺母27，可以有效避免螺钉轴10脱落。
结合图7，自锁手柄3的端部设置有具有拉钩29的上臂钩16，拉钩29与油门操纵手柄11的第一凹槽22配合，从而可以实现自锁，油门操纵手柄11上的油门拉钩29孔，可以有效的使油门拉线挂钩24挂住，避免脱落。
结合图8，左壳体4上设置的通孔39使螺钉轴10穿过，设置的扇形通孔33使拨叉20穿过，设置的插孔37使复位扭簧14的一个端部穿过。
设置的定位轴15与卡槽21内的弹簧片13抵接，设置的锁定轴17使自锁手柄3绕其转动。
手把壳体内设置的停车线护槽41，用来安装停车线护套34；设置的油门线护槽42，用来安装油门线护套35。
结合图9，油门操纵手柄11设置的第一凹槽22，其配置成与拉钩29配合；设置的油门挂钩孔23，其配置成与油门拉线挂钩24配合；设置的挡板25，其配置成与复位扭簧14的一端相抵靠；设置的螺钉套管40，其配置成套设螺钉轴10。
结合图10和图11，油门操纵手柄11的另一面设置的挡块28，其配置成与拨叉20配合。
结合图12和图13，停车手柄2包括手推柄38和弹簧片13，手推柄38设置有两个插口36，弹簧片13的两个端部卡入两个插口36中，实现与手推柄38的相对固定，手推柄38上设置的挂钩孔12，配置成与停车拉线挂钩19配合。
结合图14-图16，自锁手柄3包括锁柄32和上臂钩16，锁柄32和上臂钩16通过凸起44和第二凹槽43的配合，实现相对固定，在相对固定的部分形成完整的套管30，套管30具有的锁定孔31与锁定轴17配合，实现转动连接。
结合图17和图18，上臂钩16的一个端部形成拉钩29，其配置成与第一凹槽22配合，上臂钩16的另一个端部形成套管30的部分，这部分也有锁定孔31和第二凹槽43。
结合图19，左壳体4设置的插孔37，其配置成与复位扭簧14的另一端配合，实现两者的相对固定。
结合图20，油门限位手柄1上的拨叉20，其配置成与油门操纵手柄11上的挡块28配合，实现对油门操纵手柄11的限位。
一般的，双拉线操纵手把安装在汽油机上，而汽油机一般为二冲程低排放的汽油机，且用在一些便携式工具上，例如：背负式吹风机、背负式喷雾喷粉机、停车机械控制机构等。
