The utility model adopts the technical proposal that: for solving the technical problem, the utility model provides a cable is fallen and is used quick-release mechanism, including couple, casing, trace, dog and handle, the trace is located in the casing, including trace one, trace two, trace three and trace four, trace one, trace two, trace three and trace four order connection formation connecting rod linkage structure, trace one end with the handle is connected, the handle is located the one end of casing, trace cross the bolt with the other end of casing is connected, makes trace four wind the bolt rotates, be provided with the dog on the casing, the couple with dog looks adaptation forms the hook structure that can the switching, the handle drives under the exogenic action trace one will through the power transmission the couple is followed shirk on the dog.

In the above scheme, handle one end is cyclic annular, and the other end parallel arrangement has two slide bars, be provided with in the casing with two slide rails of slide bar looks adaptation make the slide bar clearance fit insert in the slide of casing.

In the technical scheme, the first linkage rod is provided with the spring, the other end of the spring is connected to the inner part of the other end of the shell, the spring is not stressed when the handle is not pulled, and otherwise, the spring is stressed when the handle is pulled.

In the scheme, the shell is provided with the safety shifting lever for limiting the displacement of the handle, and the handle works after the safety shifting lever is pulled out.

In the above scheme, the quick release mechanism further comprises a hanging ring assembly, the hook is fixed on the hanging ring assembly, and the hanging ring assembly is fixed on the shell.

The utility model has the advantages that: after the structure is adopted, the handle is adopted to drive the connecting rod mechanism to control the opening and closing of the hook, so that the throwing mechanism on the hook can be quickly detached; the double safety locking mechanism is designed, so that the stability and reliability of the device in the use process can be ensured.

Drawings

The invention will be further described with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic diagram of the system of the present invention;

FIG. 2 is a diagram of the internal structure of the system of the present invention;

FIG. 3 is a schematic view of the hook lock of the present invention;

fig. 4 is a system action diagram of the present invention;

fig. 5 is a releasing view of the hook of the present invention.

The device comprises a hanging ring assembly 1, a hook 2, a shell 3, a safety deflector rod 4, a handle 5, a linkage rod I6, a linkage rod II 7, a linkage rod III 8, a linkage rod IV 9, a bolt 10, a spring 11, a sliding rod 12 and a stop block 13.

Detailed Description

The following embodiments are further detailed in the following description:

the quick release mechanism for cable drop comprises a hanging ring component 1, a hook 2, a handle 5, a mechanism shell 3, a safety deflector rod 4 and the like.

The quick release mechanism is a device for quickly throwing and placing suspension equipment, a suspension ring and a support are arranged in a suspension ring assembly 1, the suspension ring is generally suspended on an electric winch of a helicopter, a task device is hooked on a hook 2, and a sliding rope for cable descent is generally used.

In the embodiment, when the task equipment needs to be thrown quickly, the safety deflector rod 4 is pulled, the handle 5 is pulled, the mechanical mechanism in the mechanism shell 3 is actuated, the hook 2 is unlocked, and the task equipment hung on the hook 2 is released, so that the task equipment is thrown.

In fig. 2, the internal structure of the system is detailed, and it mainly includes a linkage rod i 6, a linkage rod ii 7, a linkage rod iii 8, a linkage rod iv 9, a pin 10, a spring 11, and a sliding rod 12. The pin 10 plays a role in safety locking, and when the pin 10 is inserted into the through hole of the linkage rod four 9, the linkage rod four 9 cannot move.

In the embodiment, when the task equipment needs to be thrown quickly, the safety deflector rod 4 is pulled to rotate towards the lower right, the bolt 10 is pulled out, and therefore the safety protection mechanism of the equipment is released, and the figure 4 shows. At this time, the handle 5 is pulled to the left, and the slide bar 12 slides in the mechanism case 3. The handle 5 drives the linkage rod I6 to move to the left, and then the linkage rod II 7 rotates to the left. When the linkage rod II 7 rotates to the left, the linkage rod III 8 is driven to move to the left upper side, and then the linkage rod IV 9 is driven to rotate to the left. At this time, the hook 2 is released from the stopper 13 above the linkage rod four 9, as shown in fig. 5. During the disengagement of the system, the spring 11 is always under load, and the system overcomes the force of the spring during the whole movement. After the release, the link and the handle 5 are restored to the original positions, but the hook 2 needs to be manually reset.

The quick release mechanism is a device for quickly throwing and placing suspension equipment, and particularly relates to a rope descending device capable of being quickly released. The cable landing device is applied to the scene that the helicopter rapidly seeks and lands fighters at a designated task place.

The quick-release mechanism is a device for quickly throwing and placing suspension equipment, and can also be used for quickly releasing a rescue hanging basket. The rescue hanging basket is applied to rescue scenes of trapped people on land and at sea.
