Description

紧急自锁宠物牵引器
技术领域
本发明涉及一种宠物牵引器，特别是一种紧急自锁宠物牵引器。
背景技术
目前的可伸缩宠物牵引器都是利用一个手动机构来锁住绳子转盘，来控制绳子伸缩的长度，达到控制宠物的活动范围，如可伸缩牵狗器。但是在遛宠物时，人往往不会全神贯注地注意着宠物的行动。当人不注意时，宠物看到喜欢的东西、突然受到惊吓或调逗，宠物会突然乱窜，冲到马路撞上机动车，狗等易伤人伤物的宠物还会扑向人或物，伤人或伤物。极易给主人造成经济损失，给他人造成身体伤害和财产损失。
发明内容
针对以上问题，本发明的目的是提供一种当宠物突然闯出或闯起时能自锁的紧急自锁宠物牵引器。特别适合用于牵引狗等易伤人伤物的宠物。
一种紧急自锁宠物牵引器，包括项圈扣、绳带、绳带轮盘、壳体和握柄，其特征在于：还包括紧急自锁机构，紧急自锁机构包括设置在壳体外表面上并插入壳体内的开关滑块、设置在壳体内并与开关滑块连接的自锁滑块及其回位弹簧，设置在绳带轮盘外表面上且一端铰接在绳带轮盘上的自锁挡片、自锁挡片回位扭簧和设置在绳带轮盘外表面相应部位上的自锁挡片挡块。
本发明的目的是通过紧急自锁机构实现的。当宠物突然闯出或闯起时，紧急自锁机构能自动地锁住绳子转盘，控制绳子拉出，使宠物难以乱窜，难以扑向人或物。能更好地保护宠物，使宠物难以突然乱窜，冲到马路撞上机动车；使宠物难以扑向人或物，伤及他人或物；从而确保宠物的安全、他人身体健康和财产不受破坏，充分保证主人的经济不受损失。
附图说明
图1是本发明的结构示意图，
图2是图1A-A向剖视图，
图3是图1B部放大图，
图4是图1的锁定结构示意图，
图5是图4的C部放大图。
图中：开关滑块1、回位弹簧2、牵引绳开关3、自锁开关垫片4、自锁滑块5、自锁挡片6、绳带轮盘7、自锁挡片回位扭簧8、自锁挡片转轴9、自锁挡片挡块10、壳体11、握柄12。
具体实施方式
以下结合附图和实施例进行详述：
图中是一种牵狗器，一种能紧急自锁的牵狗器。包括项圈扣、绳带、绳带轮盘7、壳体11和握柄12，要点是：还包括紧急自锁机构，紧急自锁机构包括设置在壳体11外表面上并插入壳体11内的开关滑块1、设置在壳体11内并与开关滑块1连接的自锁滑块5及其回位弹簧2，设置在绳带轮盘7外表面上且一端铰接在绳带轮盘7上的自锁挡片6、自锁挡片回位扭簧8、自锁挡片转轴9和设置在绳带轮盘7外表面相应部位上的自锁挡片挡块10。
当将开关滑块1向前推时，设置在壳体11内并与开关滑块1连接的自锁滑块5随之向前滑动，头端伸入至绳带轮盘7边缘内与壳体11间的相应空间中。当牵引绳正常拉伸时，自锁挡片6在自锁挡片回位扭簧8的作用下，原位随着绳带轮盘7转动(见图1)。当加速度达到一定大的时候，即快速拉动绳时，在惯性力的作用下，自锁挡片6克服自锁挡片回位扭簧8的约束绕自锁挡片转轴9转动，转至贴靠在自锁挡片挡块10上时，自锁挡片6完全展开，随着绳带轮盘7转至自锁滑块5位置时，被伸入至绳带轮盘7边缘内与壳体11间的相应空间中的自锁滑块5的头端挡住不能继续转动，从而使绳带轮盘7停止转动(见图4)，牵引绳不能再被拉出，实现紧急制动目的；也就是：当宠物突然闯出或闯起时，拉动绳子的速度极快，紧急自锁机构起作用。当牵引绳的拉伸力消失时，自锁挡片6在自锁挡片回位扭簧8的作用下恢复初始状态(见图1)。所以，当需要紧急自锁时，只要将开关滑块1向前推至定位即可。开启紧急自锁机构时，不影响正常的拉伸绳子。
为使结构紧凑简单，自锁挡片挡块10直接设置在绳带轮盘7上，即自锁挡片挡块10为凸起在绳带轮盘7上的凸块(如图所示)。为了便于安装开关滑块1、自锁滑块5及其回位弹簧2，图中还包括自锁开关垫片4。
