Problems solved by technology

[0002] At present, most of the starting parts of the detacher used in the field of ejection lifesaving or airborne airdrop in China adopt a soft lock pin structure with densely wound spring wires, which can only transmit the starting signal, and cannot transmit the dynamic pressure and static pressure signals.
The soft lock pin of the starting part of this kind of unlocker, on the one hand, because the soft lock pin is a tightly wound spring and is in a sealed state, it is difficult to clean the surface treatment, which makes it easy to corrode after surface treatment; When the load is large, the soft lock pin will be elongated or deformed. On the other hand, the connecting part of the soft lock pin and the detacher is a cylindrical surface fit. After the soft lock pin is pulled out, there will be an unsealed channel in the main body of the detacher, which will not prevent dust. , not to mention being airtight, there is a risk of stagnation
At present, most detachers use the soft lock pin as the starting part, which has certain risks

Embodiment Construction

[0027] The present invention will be described in further detail below.

[0028] figure 1 is a schematic diagram of the quick start joint structure, such as figure 1 As shown, this embodiment provides a quick-start joint, including a joint seat, a nozzle assembly, a claw assembly, a pull rod assembly, etc., and an O-ring 2, a nozzle assembly 3, and a pin 4 are installed on the joint seat 1. Washer 5, claw assembly 6, pull rod assembly 7.

[0029] in, figure 2 is a schematic diagram of the tie rod assembly, combined with figure 1 with figure 2 As shown, the pull rod assembly 7 includes a sleeve 7A, a spring 7B, a pull rod 7C, a washer 7D, a special screw 7E, a pin 7F, and a joint ring 7G.

[0030] The sleeve 7A is a circular sleeve structure, with a stepped hole in the center to guide the gasket 7D, the spring 7B and the pull rod 7C respectively. inclined plane. The pull rod 7C is a cylindrical surface, and the front end is provided with a symmetrical milled and flatte...

Abstract

The invention is suitable for the fields of ejection lifesaving and airborne landing, and discloses a quick starting joint which mainly comprises a joint seat, a filler neck assembly, a pin, a gasket,a clamping jaw assembly and a pull rod assembly; after receiving a start instruction, the pull rod assembly and the joint seat generate relative motion; when a joint assembly moves, a clamping jaw ofthe clamping jaw assembly is driven to rotate, so that a locking part of the clamping jaw assembly is opened and quickly disengaged from a locked part, the locked part is quickly disengaged from a locked main body, the purpose of quick disengagement is achieved, a subsequent mechanism unlocking device works, and time delay caused by slow starting is avoided.

Description

technical field [0001] The invention belongs to the field of application of ejection lifesaving and airborne airdrop, and relates to a quick-start connector; when ejection life-saving or airborne airdrop, after receiving the start instruction, the locked parts are quickly disengaged, and the dynamic pressure of the aircraft is still guaranteed after the quick-start connector is disengaged And the airtightness of the static pressure system. Background technique [0002] At present, most of the starting parts of the detacher used in the field of ejection lifesaving or airborne airdrop in China adopt a soft lock needle structure tightly wound with spring wires, which can only transmit the starting signal, and cannot transmit the dynamic pressure and static pressure signals. The soft lock pin of the starting part of this kind of unlocker, on the one hand, because the soft lock pin is a tightly wound spring and is in a sealed state, it is difficult to clean the surface treatment,...
