The bushing 6 has a slot on its side. The steel cable connector 5 is a rope with a cylindrical end. After the connector 5 is inserted into the through hole of the special nut 4, the cylindrical block is placed into the bushing 6, and the cylindrical block is limited by the small hole of the bushing 6. The bushing 6 is then screwed into the special nut 4, and limited by the closing hole of the special nut 4. The outer side of the special screw 2 is the external thread that matches the special nut 4. One end of the special screw 2 is closed, and T-shaped slots are opened on both sides. The hook 1 is a closed pull hook. The two ends of the hook 1 are placed into the T-shaped slots of the special screw 2. The special screw 2 is then screwed into the special nut 4 from the non-closing end of the special nut 4.

[0030] It also includes a locking plate 3, which is made of aluminum or aluminum alloy, is a soft material, is easy to bend, and has a plate-like structure with a round center and straight ends; the special nut 4 has anti-loosening holes on both sides, and the locking plate 3 is screwed into the special nut 4 by threads, with both ends bent and snapped into the anti-loosening holes of the special nut 4.

[0031] Hook 1 is inserted into special screw 2 and then locking piece 3 is placed in. Special screw 2 has a through hole in the middle and the two T-slots of special screw 2 are connected in the middle. Locking piece 3 is placed inside special screw 2 and the straight piece of locking piece 3 extends out from the two T-slots.

[0032] The outer side of the special nut 4 has a hexagonal structure.

[0033] A parachute deployment connection mechanism includes a special nut 4, two cable connectors 5, and two bushings 6. The special nut 4 has a structure with internal threads and double-ended through holes, one end of which has a constricted opening. The bushing 6 has a connecting structure with a large hole at one end and a small hole at the other end. The outer side of the bushing 6 is provided with an external thread that matches the special nut 4. The bushing 6 is shorter than the internal through hole of the special nut 4. The bushing 6 has a slot on its side. The cable connector 5 is a rope with a cylindrical block at one end. After the cable connector 5 is inserted into the through hole of the special nut 4, the cylindrical block is placed into the bushing 6, and the cylindrical block is limited by the small hole of the bushing 6. The bushing 6 is then screwed into the special nut 4, and limited by the constricted opening of the special nut 4. The cylindrical block of the other cable connector 5 is placed into the other bushing 6, and the cylindrical block is limited by the small hole of the bushing 6. The bushing 6 is then screwed into the special nut 4 from the other direction.

[0034] It also includes a locking plate 3, which is made of aluminum or aluminum alloy, is a soft material, is easy to bend, and has a plate-like structure with a circle in the center and a straight plate at one end; a special nut 4 has an anti-loosening hole on one side, and the locking plate 3 is screwed into the special nut 4 by threads, with one end bent and fastened into the anti-loosening hole of the special nut 4.

[0035] The cylindrical block of another steel cable connector 5 is placed into another bushing 6, and then the locking plate 3 is placed in the other bushing 6. The straight piece of the locking plate 3 extends out from the slot of the other bushing 6.

[0036] The outer side of the special nut 4 has a hexagonal structure.

[0037] Example 2:

[0038] A parachute deployment connection mechanism is characterized by comprising six parts: a hook 1, a special screw 2, a locking plate 3, a special nut 4, a cable connector 5, and a bushing 6. The cable connector 5 is inserted through the special nut 4 and hooked into the bushing 6. The bushing 6 is then screwed into the special nut 4. The hook 1 is hooked into the special screw 2, and the locking plate 3 is inserted and screwed into the special nut 4. Finally, the two ends of the locking plate 3 are bent and fastened into the anti-loosening holes of the special nut 4, thus forming the parachute deployment connection mechanism. The cable connector 5 of this mechanism connects to the deployment power of the parachute opener, while the hook 1 connects to the parachute deployment lines, thus connecting the opener to the parachute. When the cable connector outputs tension, the parachute pack is pulled open, thereby deploying the parachute.

[0039] Special screw 2 and bushing 6 are connected to special nut 4 by threads.

[0040] The special nut 4 has a larger through-hole diameter, making it easy for the head of the steel cable connector 5 to pass through; the special nut 4 is hexagonal and can be clamped with tools; it has symmetrical anti-loosening holes around its perimeter for easy and secure installation.

[0041] The cable connector 5 is inserted through a special nut 4 and hooked into a bushing 6. The bushing 6 is then screwed into the special nut 4 via threads, preventing the cable connector 5 from being pulled out. Here, the head of the cable connector 5 is large enough to fit through the special nut 4. The bushing 6 has a small aperture but a slotted side, allowing the cable portion of the cable connector 5 to be embedded. By screwing the bushing 6 into the special nut 4 via threads, the cable connector 5 cannot be pulled out, thus fixing the cable connector 5 to the umbrella-opening connection mechanism.

[0042] After hook 1 is inserted into special screw 2, hook 1 can also be fixed to the umbrella-opening connecting mechanism. Here, the head of hook 1 is large and cannot be detached after being inserted into the groove of special screw 2.

[0043] Hook 1 is open, allowing closed or looped paracord to be hooked and connected to this parasol opening connection mechanism.

[0044] Hook 1 is inserted into special screw 2, then locking plate 3 is placed in and screwed into special nut 4 via threads. Finally, the two ends of locking plate 3 are bent and fastened into the anti-loosening holes of special nut 4. Locking plate 3 is made of aluminum or aluminum alloy, a flexible material that is easy to bend, and has a plate-like structure with a round center and straight ends. With the two ends of locking plate 3 bent and fastened into the anti-loosening holes of special nut 4, the entire parachute opening connection mechanism is completely fixed and cannot be loosened by any vibration.

[0045] Pull the bent parts at both ends of the locking plate 3 out of the anti-loosening holes of the special nut 4 and remove them in the opposite direction. The entire parachute opening connection mechanism can then be completely disassembled, thus detaching the parachute opener from the parachute.

[0046] Except for the locking plate 3, which is made of aluminum or aluminum alloy, all other parts are made of steel or stainless steel. The size is determined according to the size of the objects connected at both ends and the magnitude of the pulling force.

[0047] After the locking plate 3 is bent at both ends and inserted into the anti-loosening holes of the special nut 4, the outer surface of the entire mechanism is completely smooth, without burrs or sharp corners, making it particularly suitable for installation and connection on parachutes or cloth-like objects.

[0048] The parachute opening connection mechanism of the present invention is a rigid structure that is resistant to vibration, loosening, and tearing of fabrics or non-metallic objects. At the same time, the system is easy to install, connect, and disassemble, and is highly efficient. It is particularly suitable for devices where it is inconvenient to disassemble both ends but a connection is required.

[0049] This invention discloses a parachute deployment connection mechanism, which can serve as a connection mechanism between the parachute deployer and the parachute. This parachute deployment connection mechanism is reliable, easy to connect and disassemble, highly efficient, simple in structure, and low in cost. It can also be applied to devices requiring connection where disassembly at both ends is inconvenient. This parachute deployment connection mechanism can be applied in various fields such as industry, aviation, aerospace, shipbuilding, and weaponry.
