Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

In a specific implementation of the utility model, as shown in fig. 1 to 4, a quick connector for the rear suspension of a tractor is proposed, comprising:

The hook body 1, the hook body 1 is in a special structure, the hook tip of the hook body 1 is processed with a concave groove, and the lower part of the hook body 1 is in a half-open structure which is integrally formed and processed;

The spring limiting pin 2 is positioned in the hook body 1, one end of the spring limiting pin 2 is fixed on one side wall of the hook body 1, and the other end of the spring limiting pin 2 is connected with a matched limiting spring 4;

The limiting device cavity 3 is integrally formed and processed at the lower part of the hook body 1, the limiting device cavity 3 is of a semi-open cavity structure, and a transmission mechanism consisting of a spring limiting pin 2, a limiting spring 4, a trigger 5 and a locking device is assembled in the limiting device cavity 3;

The limiting spring 4, one end of the limiting spring 4 is connected with the spring limiting pin 2, and the other end of the limiting spring is connected with the trigger 5 through the other spring limiting pin 2, so that the stroke limit of the trigger 5 and the lock 6 is realized;

The trigger 5 is assembled at one end of the limiting device cavity 3, the lower part of the trigger 5 is connected with the bottom cavity surface of the limiting device cavity 3 through the spring limiting pin 2, and the trigger 5 is connected with the end part of the front limiting spring 4;

The lower part of the locking device 6 is fixed on the trigger 5 through a bolt, the side part of the locking device 6 is connected with the hook body 1 through the spring limiting pin 2, and the locking device 6 is opened and closed by rotating the trigger 5 and pulling the limiting spring 4.

In one embodiment of the present utility model, as shown in fig. 1 to 4, the working principle of the present utility model is as follows: when the locking device 6 needs to be opened, the trigger 5 is rotated through the shaft body at the lower part of the trigger 5, and the trigger 5 is integrally connected with the locking device 6, so that the locking device 6 also rotates along with the trigger 5, the notch is opened, after the hook body 1 is connected with other parts hung behind a tractor, the trigger 5 is only required to be released, and the trigger 5 is reset under the pulling force of the limiting spring 4 of the spring limiting pin 2, so that the locking device 6 is driven to be closed.

While there has been shown and described what is at present considered to be the fundamental principles and the main features of the utility model and the advantages of the utility model, it will be understood by those skilled in the art that the utility model is not limited to the foregoing embodiments, but is described in the foregoing description merely illustrates the principles of the utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as hereinafter claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
