Connecting device used between airport trailers

Abstract

The invention discloses a connecting device used between airport trailers. The connecting device comprises a T-shaped fixing seat, a U-shaped mounting seat is fixedly connected to the right side of the T-shaped fixing seat, a mounting block is fixedly connected to the top of the U-shaped mounting seat, a pull pin is arranged on the right side of the T-shaped fixing seat, a circular hole is formed in the top of the mounting block, and the pull pin is slidably arranged in the circular hole in a sleeved mode. The bottom end of the pull pin extends into the U-shaped mounting seat, an insertion hole is formed in the inner wall of the bottom of the U-shaped mounting seat, the pull pin is matched with the insertion hole, and the installation block is provided with an automatic bouncing and inserting mechanism and an automatic locking mechanism which are matched with the pull pin. The device is reasonable in design, the purpose of automatically bouncing off and locking a dragging pin is conveniently achieved when a push block is extruded after a pull handle of a rear vehicle is inserted, manpower is liberated, meanwhile, the fixing efficiency is improved, locking and falling prevention of the dragging pin are conveniently and automatically achieved in the process of pulling up the dragging pin, personnel operation is facilitated, the working efficiency is improved, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of trailer connection equipment, in particular to a connection device used in an airport trailer workshop. Background technique [0002] The airport trailer is a trailer used for short-distance transportation of airport cargo. During the trailer operation, two vehicles need to be pulled together, so a connecting device is needed. Most of the connecting devices in the existing airport trailer workshop are composed of towing pins, fixing seats Composed of a U-shaped seat, it is connected with the mop of the rear car through the towing pin; in the existing connecting device of the airport towing workshop, the towing pin does not have the function of automatically springing off and locking, and the mop of the rear car moves to the mop of the towing pin. When it is down, most of the existing personnel manually move down the drag pin and lock it. The manual locking method is inefficient, and it is easy to forget t...

Problems solved by technology

[0002] The airport trailer is a trailer used for short-distance transportation of airport cargo. During the trailer operation, two vehicles need to be pulled together, so a connecting device is needed. Most of the connecting devices in the existing airport trailer workshop are composed of towing pins, fixing seats Composed of a U-shaped seat, it is connected with the mop of the rear car through the towing pin; in the existing connecting device of the airport towing workshop, the towing pin does not have the function of automatically springing off and locking, and the mop of the rear car moves to the mop of the towing pin. When it is down, most of the existing personnel manually move down the drag pin and lock it. The manual locking method is inefficient, and it is easy to forget to lock it, and it is not convenient to automatically lock when the drag pin is pulled up. It is solid and anti-drop, which cannot meet the needs of use. Based on the above situation, we will improve it. Therefore, we propose a connection device for airport trailer workshops to solve the above problems.
