An interlocking device for a service vehicle

Abstract

This utility model discloses an interlocking device for a service trolley, belonging to the field of mechanical engineering technology. It includes an interlocking device base, eight positioning bolts, mounting bolts, and a fixing plate. A linkage box is fixedly connected to the top of the interlocking device base, and a locking pin is fixedly connected to the top of the linkage box. Two positioning blocks are fixedly connected to the top of the interlocking device base, and an electric push rod is provided on one side surface of each of the two positioning blocks. This utility model, by setting a shock-absorbing component consisting of a drive motor, a threaded screw, a screw hole adjusting plate, an adjusting slide rod, and a spring, adds a targeted shock-absorbing and buffering function compared to traditional interlocking devices. This allows the interlocking device to absorb impact force through the elastic deformation of the spring when the service trolley vibrates or is subjected to load impact, reducing component wear and loosening caused by rigid connections, and significantly improving the long-term reliability of the interlocking device.
