Detailed Description

Example 1

A novel unhooking mechanism is disclosed, as shown in figures 1-3, and comprises two main body plates 1, wherein a hook 2 is arranged on the upper portion between the main body plates 1, a lock catch 3 is arranged at the bottom of the hook 2, a quincunx lock 9 is connected to the bottom end of the lock catch 3, a D-shaped lock catch 8 is connected to the bottom end of the main body plate 1, when the mechanism is fixed by the D-shaped lock catch 8, the hook 2 provides a hanging point for an object to be lifted, the hook 2 and the lock catch 3 are both connected with the main body plates 1 on two sides through a screw 5, the screw 5 on the upper portion is rotatably connected with the hook 2, the screw 5 on the lower portion is rotatably connected with the lock catch 3, so that the hook 2 and the lock catch 3 can flexibly rotate, a spring connecting ring 10 is installed at the bottom end of the lock catch 3, a tension spring 7 is arranged between the D-shaped lock catch 8 and the lock catch 3, one end of the tension spring 7 is connected with the D-shaped lock catch 8, and the other end of the tension spring connecting ring 10 is connected with the spring connecting ring 10.

In this embodiment, the main body plates 1 are connected by a connecting shaft 11, and a nut is installed at an end of the connecting shaft 11 to ensure connection between the two main body plates 1.

Specifically, be provided with stop collar 4 between the main part board 1, the internal connection of stop collar 4 has spacing axle 41, the outer wall that main part board 1 was run through at the both ends of spacing axle 41 and install the nut, heavy burden carry the load after, its gravity is by stop collar 4, screw rod 5 converts torsion into and arrives the stress point between couple 2 and the hasp 3, conduct for hasp 3 through the stress point, because of the stress point of hasp 3, stop collar 4, the tangent line of

screw rod

5 and 2 atress of couple is on same straight line, and under the effect of extension spring 7 in addition, so couple 2 can bear big gravity and can not let hasp 3 unhook, will "lift up the heavy object" initiative and drop when needs, loosen couple 2, leave its stress point can.

In this embodiment, the two ends of the screw 5 are provided with the anti-slip nuts 6 for ensuring the fixation of the screw 5.

Example 2

On embodiment 1 basis, further guarantee couple 2 and can provide the carry point for the object that promotes, couple 2 is close to 3 departments of hasp and sets up flutedly, and the recess can make things convenient for couple 2 to be connected the heavy object fixedly, and

couple

2 and 3 mutual joint cooperations of hasp guarantee couple 2 and hasp 3 be connected fixedly.

In this embodiment, the D-shaped latch 8 is rotatably connected to the main body plate 1 through a latch shaft 81, which facilitates the connection and rotation of the D-shaped latch 8.

Collars 82 are mounted at both ends of the lock shaft 81 for limiting both ends of the lock shaft 81.

When the novel unhooking mechanism is used, firstly, a D-shaped latch 8 of the novel unhooking mechanism is fixed on a lifting device, then a hanging point is provided for an object lifted through a hook 2, a heavy object is hung on the hook 2 for fixing, then the hook 2 is manually extruded downwards to rotate, so that a hook mouth at the top of a latch 3 is extruded and clamped, the hook 2 is connected with the latch 3, after the heavy object is hung, the generated pulling force is converted into the torque force through a limiting sleeve 4 and a screw rod 5 to reach the stress point between the hook 2 and the latch 3, the torque force is transmitted to the latch 3 through the stress point, under the pulling action of a tension spring 7, the hook 2 and the latch 3 are clamped and fixed, the latch 3 can bear large gravity and cannot be unhooked, when the lifted heavy object is required to be actively dropped, the latch 3 is manually rotated to be turned over anticlockwise, so that the hook 2 is separated from the latch 3, and the hook 2 can be loosened, ensuring that the hook 2 leaves its point of stress and is unhooked.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the scope of the present invention.
