TECHNICAL FIELD
[0001] The utility model belongs to the technical field of parachute protection lifesaving, and particularly relates to a flip type manual disengaging device. BACKGROUND
[0002] According to the parachute system use specification, after a parachutist completes a parachute task, the parachutist needs to perform a man-parachute separation operation before landing or water landing, so as to avoid personnel casualties caused by the dragging of the parachute system by strong wind or sea waves. The currently commonly used parachute system separation devices in China are shoulder release type and abdominal release type, and a disengaging lock is installed between a parachute system control belt and a back strap. During normal flight, the disengaging lock is used to safely constrain the parachutist together with the back strap and the control belt, and the parachutist realizes man-parachute separation by releasing the parachute system through the disengaging device before landing or water landing. Since the disengaging device directly contacts the human body shoulder or abdomen, the structure of the disengaging device needs to be as light as possible to improve the overall wearing comfort. SUMMARY
[0003] The utility model aims to provide a miniaturized and light-weight parachute system flip type manual disengaging device.
[0004] The utility model adopts the technical scheme as follows: a flip type manual disengaging device, including a lock body and a lock piece, one end of the lock body is connected with a control belt, and the lock body is internally provided with a cavity structure, one end of the lock piece is inserted into the cavity to realize locking and unlocking, and the other end of the lock piece is connected with a back strap, the cavity of the lock body is provided with a lock latch, a sliding block, a lock pin and a sliding block spring, the cavity port is provided with a horn mouth guide groove, the sliding block is provided with the lock latch and the lock pin which are used to constrain the sliding block, one end of the sliding block is provided with the sliding block spring which is used to provide spring force for the sliding block, the other end of the sliding block is provided with a protrusion, the lock piece is provided with a groove, and the groove on the lock piece is connected with the protrusion on the sliding block in a matched mode, the lock latch is rotated to release the constraint between the lock latch and the lock pin, at this time, the sliding block spring pushes the sliding block and the lock piece to move to the outside of the lock body, and after the sliding block and the lock piece are guided by the guide groove, the sliding block and the lock piece will no longer be limited by the lock body, so that the lock piece and the sliding block can be released to realize unlocking.
[0005] In the above scheme, the lock latch is provided with a handle which is used to open the lock latch.
[0006] In the above scheme, the lock latch is provided with a lock latch spring which is used to provide spring rebound force for the lock latch.
[0007] In the above scheme, the lock latch is provided with a handle spring which is used to provide spring rebound force for the lock latch.
[0008] In the above scheme, the disengaging device further includes a lock cover, and the lock cover is provided with the lock latch which is used to fix the lock cover.
[0009] In summary, due to the adoption of the technical scheme, the step-by-step unlocking mode has good safety, the mechanical interface can be interconnected with the existing parachute system and the harness system, has good versatility, and can be applied to the shoulder release type parachute system of the lifesaving parachute, the paratrooper parachute and the civilian sports parachute.

[0016] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.
[0017] A parachute system flip type manual disengaging device, including lock body 101, lock cover 102, lock latch 107, handle 103, plug pin, sliding block 108, safety latch 104 etc. The sliding block 108 can be connected with the lock piece on the harness, and the lock body 101 can be connected with the control band.
[0018] As shown in the drawing, Figure 1 Wherein the lock body 101 is the basic structural member of the whole device, one end can be fixedly connected with the parachute control band through the connecting pin, the other end is connected with the harness through the lock piece 105, and the harness and the control band are matched to complete the restraint function and the connection function of the parachutist.
[0019] When landing or water landing after the parachute task is finished, the restraint of the parachute system and the parachutist needs to be released. As Figure 3As shown, first open the safety latch 104 and the lock cover 102 in turn, as shown Figure 4 、 Figure 5 Then dial the handle 103, drive the lock latch 107 to rotate, and release the constraint between the lock latch 107 and the lock pin 109. At this time, the slider spring 111 pushes the slider 108 and the lock piece 105 to move outwards. The lock body 101 is designed with a trumpet guide slot at the port, and the lock piece 105 will no longer be limited by the lock body 101 after moving to the guide slot, that is, the cooperation between the lock piece 105 and the slider 108 is released, and unlocking is realized.
[0020] After unlocking, the device can be relocked. The lock piece 105 is pushed along the limiting slot designed at the end of the lock body and cooperates with the slider 108, the slider 108 is pushed to the specified position by the lock piece 105, and then the lock pin 109 is rotated and reset. At this time, the handle 103 and the lock latch 107 are rotated and reset under the action of the handle spring 110, the lock latch 107 presses and fixes the lock pin 109, the lock cover 102 drives the safety latch 104 to rotate and reset under the action of the lock cover spring, and the locking of the whole device is completed.
[0021] The above technical scheme is only a preferred embodiment of the present application, and of course cannot limit the scope of the present application. Therefore, equivalent changes made within the scope of the present application still belong to the protection scope of the present application.
