Anti-locking saddle locking mechanism

Abstract

The invention discloses an anti-locking saddle locking mechanism which comprises a lock hook, a pin block, a tension spring and a lock hook spring. The lock hook spring enabling the lock hook to rotate around a hinge pin is arranged on the lock hook. The pin block is located between the lock hook and a rear beam board. The two ends of the tension spring pulling the pin block to slide on the rear beam board are connected with the rear beam board and the pin block respectively. The wedge-shaped face of the lock hook is of a step shape. The wedge-shaped face of the pin block is of a step shape matched with the wedge-shaped face of the lock hook. The anti-locking saddle locking mechanism has the advantages that the mutually-matched surfaces of the lock hook and the pin block are respectively of a step structure, so that it is guaranteed that a certain gap is kept between the matching faces of the lock hook and the pin block, the phenomena that a traction pin is locked and is difficult to take out and hang due to the fact that the lock hook and the pin block are tightly attached to each other are avoided, an existing manual saddle lock hook and pin block gap adjusting device is omitted, the reliability and the economical efficiency of a saddle are improved, and the gap between the lock hook and the pin block can be automatically adjusted in real time and in time.

Description

technical field [0001] The invention relates to a saddle, in particular to a locking mechanism for an anti-lock saddle. Background technique [0002] The saddle locking mechanism is the part that fixes the traction pin of the trailer on the saddle. From the front of the saddle to the rear, there are horseshoe mouth, lock hook, pin block, and rear beam plate. The horseshoe mouth and rear beam plate are welded to the saddle bottom plate. , the position is fixed, and the lock hook and pin block are movable parts. After the trailer is loaded, the traction pin is located between the horseshoe mouth and the lock hook, and the wedge-shaped pin block fills the gap between the lock hook and the rear beam plate. Move in, force the lock hook to move up, and clamp the traction pin tightly between the lock hook and the horseshoe mouth. In the existing saddle locking mechanism, the mating surface of the lock hook and the pin block is a plane that cooperates with each other. The close fi...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a locking mechanism for anti-lock saddles, which keeps a certain gap between the lock hook and the mating surface of the pin block, and prevents the two from being locked due to the fit. If it is too tight, the traction pin will be locked, and it will be difficult to remove and hang.
