AI Technical Summary

Technical Problem

When the existing semi-trailer saddle traction seat is connected to the traction pin, the fixability is insufficient, which can easily cause the traction pin to shake and fall off, reducing the safety of use.

Method used

A traction seat structure including a seat body, mounting groove, sleeve, movable rod, push plate, spring, guide rod, rack, incomplete gear, outer snap and inner snap are designed, and the traction is connected by multiple channels and springs. The combination of the traction pin ensures the stability of the connection and is released through simple operation during disassembly.

Benefits of technology

Through the combination of multiple fixing and springs, the connection stability and use safety of the traction seat are improved, ensuring that the traction pin is not easy to shake and fall off during use, and simplifying the connection and disassembly operation.

Abstract

The utility model discloses a semitrailer saddle type traction seat which comprises a seat body, a mounting groove is formed in the middle of the bottom of the seat body, a sleeve block is arranged in the middle of one end in the seat body, a movable rod is arranged on the inner side of the sleeve block in a sleeved mode, and one end of the movable rod extends to the inner side of the mounting groove and is provided with a push plate. The outer side of the movable rod is sleeved with a spring A connected with the push plate, and guide rods are arranged on the two sides of the top of one end in the base body. Through the mutual cooperation of the incomplete gears, the guide rod, the connecting rod, the rack, the outer buckle, the push plate, the inner buckle, the spring A and the movable rod, the two groups of incomplete gears can be driven to rotate only by pushing the traction pin into the mounting groove during use, so that the inner buckle is clamped into the outer side of the traction pin for primary fixation, and the traction pin is prevented from being damaged. And meanwhile, the outer buckle can be clamped into the outer side of the inner buckle for secondary reinforcement, and the elastic force of the spring A can drive the push plate to apply pressure to the traction pin, so that the traction pin is prevented from shaking.
