then the hook (1) is rotated to enable the hook to fall into the clamping seat of the lock seat (2), the handle (3) is pressed along the direction from top to bottom, and the clamping shaft (5) is driven by the handle to rotate along with the handle;

because the clamping shaft [5] is provided with the half clamping groove, when the handle reaches the horizontal limit position, the flat end surface of the half clamping groove rotates to the vertical position from the horizontal position, and the clamping shaft [5] falls into the groove on the hook [1], so that the movement of the hook is limited, and the connection of the mooring joint and the mooring bolt is completed.

(5) When the mooring connector and the mooring bolt are loosened, the handle [3] is pulled upwards, the clamping shaft [5] rotates along with the handle [3] under the driving of the handle, and when the flat end surface of the half clamping groove on the clamping shaft [5] rotates from the vertical position to the horizontal position, the hook [1] is separated from the lock seat [2], and the loosening of the mooring connector and the mooring bolt is completed.

(6) The fork ear at one side of the lock seat (2) is a double fork ear.

(7) The joint arranged at the lower end of the lock seat (2) is a single-lug joint and is used for being connected with a double-lug joint of the mooring rigging.

The quick mooring joint provided by the invention can realize quick butt joint and loosening with a mooring bolt by connecting the clamping shaft, the handle, the lock seat, the hook and other parts into a whole according to a certain assembly relation, and is simple and convenient to operate and high in reliability.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a quick mooring joint, a three-dimensional diagram of which is shown in fig. 1.

The mooring joint consists of a hook (1), a lock seat (2), a handle (3), a pin (4), a clamping shaft (5) and a fastening pin (6).

The right side of the lock seat [2] is provided with a fork lug, the left side is provided with a clamping seat, and the lower end is provided with a single lug joint. The hook (1) is connected to the fork ear of the lock base (2) through a pin (4) and a clamp spring, and the handle (3) is connected to the clamping base of the lock base (2) through a clamping shaft (5) and a fastening pin (6). The single lug joint at the lower end of the lock base is used for connecting with a double lug joint (fixed on a chain ring) of the mooring rigging.

Fig. 2 is the quick hitch coupler in an open position.

Fig. 3 shows the quick hitch coupler in a closed position.

When the mooring connector is used for butt joint with a mooring bolt, the mooring connector is firstly in an open state, the opening of the lock seat [2] is aligned with the mooring bolt, and the lock seat is pushed horizontally, so that the annular bulge on the lock seat falls into the neck of the mooring bolt. Then the hook (1) is rotated to enable the hook to fall into the clamping seat of the lock seat (2), the handle (3) is pressed along the direction from top to bottom, the clamping shaft (5) is driven by the handle to rotate along with the hook, because the clamping shaft (5) is provided with the half clamping groove, when the handle reaches the horizontal limit position, the flat end surface of the half clamping groove also rotates the vertical position from the horizontal position, at the moment, the clamping shaft (5) can fall into the groove on the hook (1), and therefore the effect of limiting the movement of the hook is achieved, and the whole operation of quick connection is completed.

When the quick release is needed, the handle [3] is pulled upwards, the clamping shaft [5] rotates along with the handle [3], and when the flat end surface of the half clamping groove on the clamping shaft [5] rotates from the vertical position to the horizontal position, the hook [1] can be released from the lock seat [2 ].

Further, in the above-mentioned case,

the end of the hook (1) is provided with a groove, as shown in figure 4, for matching connection with the clamping seat of the lock seat (2).

The right side of the lock seat [2] is provided with a fork ear, and the left side is provided with a clamping seat, as shown in figure 5; and the lock seat is also provided with an annular bulge for matching with the mooring bolt.

A half clamping groove is processed on the clamping shaft (5) as shown in figure 6;

the hook (1) is connected to the fork ear of the lock seat (2) through a pin (4) and a clamp spring, and the handle (3) is connected to the clamping seat of the lock seat (2) through a clamping shaft (5) and a fastening pin (6);

when the hook is locked, the handle [3] is pressed downwards, so that the clamping shaft [5] is driven to rotate, and when the flat end surface of the half clamping groove on the clamping shaft [5] rotates from the horizontal position to the vertical position, the clamping shaft [5] falls into the groove on the hook, so that the movement of the hook is limited;

when the lock is released, the handle (3) is pulled upwards to drive the clamping shaft (5) to rotate, and when the flat end surface of the half clamping groove on the clamping shaft (5) rotates from the vertical position to the horizontal position, the hook (1) can be released from the clamping seat of the lock seat (2).

The clamping groove on the handle (3) can play a limiting role, as shown in figure 7.

The quick mooring joint provided by the invention can realize quick butt joint and loosening with a mooring bolt by connecting the clamping shaft, the handle, the lock seat, the hook and other parts into a whole according to a certain assembly relation, and is simple and convenient to operate and high in reliability.

The foregoing is merely a detailed description of the embodiments of the present invention, and some of the conventional techniques are not detailed. The scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention will be covered by the scope of the present invention.
