The invention discloses an automatic brake master cylinder and self-locking anti-theft safety device, and belongs to the field of engineering mechanical and electrical installation equipment. The device comprises a brake master cylinder and a linkage lock structure, the brake master pump comprises an upper cavity and a lower cavity which are communicated and parallel, the upper portion of the upper cavity is communicated with an oil storage device, and one side of the upper cavity is matched with the linkage lock structure to realize switching between communication and non-communication between the oil storage device and the lower cavity; and the lower cavity is matched with a main piston, and the main piston reciprocates in the lower cavity. When a key plate of the linkage lock structure is opened, a valve rod moves rightwards, oil in the oil storage device flows into a circumferential oil groove, the piston rod is moved leftwards and rightwards by treading the pedal for many times, and the oil flows into branch pumps to achieve the braking effect. During parking, when the key is taken out, the valve rod returns, the oil storage device and the lower cavity are not communicated, the pedal needs to be stepped down before the key is taken out, the key can be taken out under the braking condition, and the function not only plays an anti-theft role, but also plays a role in preventing an automobile body from sliding away.
本发明公开了一种自动制动总泵和自锁防盗的安全装置,属于工程机电安装设备领域,包括制动总泵和联动锁结构,制动总泵包括相互连通且平行的上腔体和下腔体,上腔体上部连通储油装置,上腔体一侧配合联动锁结构实现切换储油装置与下腔体之间的连通和不连通;下腔体配合有主活塞,主活塞在下腔体内实现往复运动。当联动锁结构的钥匙板打开时,阀杆右移,储油装置内的油流入周向油槽,多次踩动踏板实现左右移动活塞杆,油流入各分泵实现制动作用。停车时,取出钥匙的同时,阀杆回位,储油装置与下腔体之间不连通,取出钥匙前必需先踩下踏板,在制动的情况下才能取出钥匙,这个功能不仅起防盗作用而且也起到防止车身自身滑走的作用。
