Locomotive toilet door lock
The invention relates to a locomotive toilet door lock. The technical problems that the stability of existing like products the design of an anti-loose anti-vibration structure is poor, the linkage interlocking effect is poor, and looseness or opening is prone to generating due to vibration are solved. A transmission body of the door lock is a rectangular metal box provided with an inner cavity, end openings are correspondingly formed in the two ends of the transmission body, a locking piece of a connecting piece extends one side end opening, and a linkage mechanism is arranged in the connecting piece in the transmission body. According to the key point, the linkage mechanism comprises a shifting fork, a transmission strip and a shaft sleeve crank arm, the shifting fork, the transmission strip and the shaft sleeve crank arm are arranged in a lower frame of the connecting piece, the shifting fork is in a cylinder shape, a key hole is formed in the center of the shifting fork, and shifting lugs with sharp corners protruding are symmetrically arranged on the outer diameter of one side of the shifting fork; and the transmission strip and the shaft sleeve crank arm are correspondingly and symmetrically arranged on the two sides of a cover plate center shaft of the key hole and the transmission body, an inner hook of the transmission strip abuts against the shifting lug of one side of the shifting fork, the outer diameter of the transmission strip is in interference abutting with the inner diameter of the connecting piece for up and down pushing, and the connecting piece moves upand down.
本发明涉及一种机车卫生间门锁，是针对现有同类产品的稳定性和防松防振结构设计欠佳，联动联锁效果欠佳，由于振动而容易松动或打开的技术问题而设计。该门锁的传动体为设有内空腔的矩形金属盒体，传动体的两端分别设有端口，连接件的锁杆伸出一侧端口，传动体内连接件设有联动机构，其要点是所述联动机构包括拨叉、传动条、轴套拐臂，拨叉、传动条和轴套拐臂设置于连接件的下框架内，拨叉呈圆柱形，拨叉的中心设有钥匙孔，拨叉的一侧外径对称设有尖角凸起的拨耳；拨叉的钥匙孔和传动体的盖板中心轴两侧分别对称设置传动条和轴套拐臂，传动条的内钩与拨叉的一侧拨耳相抵，传动条的外径与连接件的内径之间过盈相抵而上下推动，实现连接件上下移动。
