Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Embodiments of the present application will be described first with reference to the accompanying drawings.

The application provides a pull wire is from locking-type couple, and pull wire is from locking-type couple includes:

the device comprises a pull wire 3, a cargo hook 4, a manual opening and closing button 5, a cargo hook limiting stop lever 6, a rotating arm 9, a reset torsion spring 10, a connecting arm 11 and an extension spring 12;

wherein, one end of the extension spring 12 is connected with the goods hook 4, and the other end is connected with the connecting arm 11;

the middle part of the reset torsion spring 10 is fixed on the rotating arm 9, one end of the reset torsion spring is arranged at the stay wire 3, and the other end of the reset torsion spring is arranged at the junction of the connecting arm 11 and the rotating arm 9;

a cargo hook limiting stop lever 6 is arranged at the opening of the cargo hook 4;

the tail end of the cargo hook limiting stop lever 6 is provided with a manual opening and closing button 5.

A compression spring 13 is arranged at the cross bar of the manual opening and closing button 5.

The shell 8 of the self-locking hook of the stay wire comprises two parts which are symmetrical left and right and are combined through bolts,

the middle position of the top end of the shell 8 is provided with a hanging rod 7.

The part of the stay wire 3 exposed out of the shell 8 is provided with a stay wire adjusting rod 2.

The pull-wire self-locking type hook is opened in the following mode, the pull wire 3 is pulled through external force, the pull wire 3 pulls the rotating arm 9 to rotate, then the reset torsion spring 10 is compressed to drive the connecting arm 11 and the goods hook 4 to rotate towards the direction far away from the goods hook limiting stop lever 6, the extension spring 12 is stretched, and the goods hook 4 is opened. As shown in particular in fig. 4.

The pull-wire self-locking hook is reset in the following mode, when external force does not exist, the reset torsion spring 10 resets to drive the connecting arm 11 to rotate towards the initial position, the extension spring 12 is compressed, and then the goods hook 4 is driven to reset.

This application can also unload the goods through manual mode. As shown in fig. 5, when the pull wire 3 is not acted by external force, the pull wire can be opened and closed through the manual opening and closing button 5, when goods are loaded and unloaded, the manual opening and closing button 5 is pressed downwards, the compression spring 13 is compressed, the goods hook limiting stop lever 6 moves to one side of the goods hook 4, and the goods can be loaded and unloaded by rotating the goods hook limiting stop lever 6 clockwise.

The internal structure state of the attached fig. 6 and fig. 7 with the outer shell 8 removed can be seen that the cargo hook limiting blocking rod 6 cannot move randomly through the interaction with the cargo hook 4, the outer shell 8 and the compression spring 13, so that the cargo transportation safety is ensured.

When the pull wire 3 is not under the action of an external mechanism, the goods hook 4 cannot rotate towards the left direction due to self-locking generated by the interaction of the rotating arm 9, the connecting arm 11 and the extension spring 12 (the intersection point of the rotating arm 9 and the connecting arm 11 is below the connecting line of two end points); due to the effect of the cargo hook limiting stopper 6 (the cargo hook limiting stopper 6 does not move freely through interaction with the cargo hook 4, the shell 8 and the compression spring 13, and the detailed description shows that the cargo hook 4 can not rotate towards the right direction), the cargo hook 4 can not open and close when being used for carrying cargoes, and the transportation safety is guaranteed.

This application is through the synergism of self mechanism, when no exogenic action, self can accurate the reseing, through self link mechanism auto-lock, hangs the goods and can not drop by oneself, guarantees transportation safety. Through the limit of the axle housing cavity and the mechanism, the stability of the internal lifting hook is ensured. The limiting stop lever mechanism can realize manual quick loading, unloading and fixing of goods, and the stop lever has a self-limiting anti-moving function, so that the safety of goods transportation is ensured. When no external force acts, the goods hook can reset when being used for hanging goods and can not open and close by self-locking, and the transportation safety is ensured.

The above-described embodiments of the present application do not limit the scope of the present application.
