The invention discloses a hasp split arrester and sports car protection device, only one locking movable component of a latch hook assembly is adopted, that is, a lock plate rotates around a pin shaft, the movement belongs to low pairs, the action links are few, the movement form is concise, and the probability of failure is greatly reduced. Meanwhile, the lock plate is specifically configured tobe divided into a first part located on the hook base side and a second part located on the hook head side with the overhead hole as the boundary, and the whole lock plate is equivalent to a lever. The first part shields part of the hook groove in the initial state, and when the first part is directly acted by the locked component, the lock plate rotates to cause the second part to gradually shield part of the hook groove, so the locked component is reversely restrained, and obviously, the action of the lock plate meets the requirements that the larger the dragging force of the locked component is, the tighter the locking is; and locking reliability is high.

    本发明公开了一种搭扣对开式挡车栏及跑车防护装置,在本发明的实施例中,所采用的锁钩总成的锁合活动构件只有一个,即锁板,锁板所做的运动是绕销轴的转动,属于低副,动作环节少,且运动形式简练,出现故障的概率大大降低。同时,锁板具体配置为以所开销孔为界所分成位于钩座侧的第一部分和位于钩头侧的第二部分,整体上相当于一个杠杆。并且第一部分在初始状态时遮蔽部分钩槽,当第一部分被被锁构件所直接作用,锁板产生转动,导致第二部分逐渐的遮蔽部分钩槽,从而反向约束被锁构件,显而易见的是,锁板的动作符合被锁部件牵扯力越大,锁合越紧的要求,具有锁合较好的可靠性。
