CONNECTOR FOR ATTACHMENT OF DETACHABLE EQUIPMENT TO EARTHMOVING MACHINE (OPTIONS) AND EARTHMOVING MACHINE CONTAINING SUCH A CONNECTOR Russian patent published in 2022 - IPC E02F3/36 E02F3/30 F16B2/00 F16B45/02 

FIELD: earthmoving equipment.

SUBSTANCE: group of inventions relates to a connector for the attachment of detachable equipment to an earthmoving machine. The connector for the attachment of detachable equipment to the earthmoving machine contains a connector case with a socket containing an inlet made with the possibility of passing a pin of detachable equipment through it to move through a passage of the socket to a socket grip area, and a retainer made with the possibility of moving out of the connector case and relatively to it. At the same time, there is a possibility of at least partial overlap of the passage of the socket to an extent sufficient to prevent the pin from moving out of the grip area by means of the specified retainer of the specified connector. In this case, the retainer is displaced to the first position of a locked passage, in which the retainer prevents the pin from moving out of the grip area and is capable of moving to the second position relatively to the passage to provide the possibility of: the entry of the specified pin into the grip area by pressing the specified pin to the retainer to move the retainer against its displacement towards the specified second position and the exit of the specified pin from the grip area by means of a leading element of the connector. At the same time, the leading element is made with the possibility of moving relatively to the connector case to connect to the retainer to ensure the possibility of moving the retainer by the leading element at least partially to its second position and to detach from the retainer, thereby preventing the movement of the position of the retainer by the leading element. Moreover, the connector additionally contains a trigger element made with the possibility of moving relatively to the connector case so that it can engage and move the specified pin when moving the pin through the passage, so that the trigger element when moving it with the specified pin provides disconnection of the leading element from the retainer.

EFFECT: safe holding of a pin of hinged equipment, protection against accidental displacement or partial connection of hinged equipment of a quick-release connection.
