The invention discloses a quick-opening lock structure of a carriage plate. A lower clamping block body is formed by smooth transition of a stepped cylinder and an arched section in the vertical direction, a lower clamping block and an upper clamping block body are arranged on the arched section of the lower clamping block body, the outer side of the lower clamping block body is matched with the shape of the lower clamping block body, and a longitudinal semicircular strip-shaped protrusion is arranged in the center of the inner side of the lower clamping block body to form a wedge-shaped body. A right-angle-shaped notch is formed in the longitudinal half position of the arch-shaped section of the upper clamping block body, an upper clamping block composed of a pit corresponding to the strip-shaped protrusion of the wedge-shaped body of the lower clamping block is arranged on the longitudinal half plane of the arch-shaped section of the right-angle-shaped notch, and the upper clamping block and the lower clamping block are matched. The lock can be reliably locked, positioned and quickly opened, the working quality and efficiency are obviously improved, and the safety of operators is protected to the maximum extent. The invention has the advantages of novel and unique conception, compact and reasonable structural design, simple and economical operation, stable and reliable working performance, suitability for industrial popularization and application and the like.

    本发明公开一种车厢厢板的快开锁具结构。它由阶梯柱体与垂直方向拱形断面圆滑过渡组成下卡块主体,在下卡块主体的拱形断面上设外侧与下卡块主体形状匹配,内侧中心有一纵向半圆条状凸起构成楔形体的下卡块和阶梯柱体与相同方向拱形断面圆滑过渡组成上卡块主体,在上卡块主体拱形断面纵向二分之一处设直角形缺口,在直角形缺口拱形断面纵向二分之一平面上设与下卡块楔形体条状凸起对应的凹陷组成的上卡块,并将上卡块与下卡块相契合而成。它能使锁具可靠锁紧定位并快速开启,明显提高工作质量与效率,以最大限度保护操作人员安全。并具有发明构思新颖独特、结构设计紧凑合理、操作简单经济适用、工作性能稳定可靠、适宜行业推广应用等优点。
