Description

Technical Field

[0001] This invention belongs to the field of umbrella carrying system, specifically a cone-shaped locking and disengaging mechanism. Background Technology

[0002] The stabilizing parachute release mechanism of the main and backup integrated parachute pack harness system currently in service in my country is a three-ring release mechanism, mainly composed of a large ring, a middle ring, a small ring, a rope buckle, a metal eyelet, and a locking pin (see...). Figure 1 Located between the main parachute and the reserve parachute pack, it can detach smoothly under different load conditions and has a simple structure. When the second-stage stabilizing parachute malfunctions, the skydiver pulls the handle to pull the steel cable out of the closed rope, the three loops separate, and the stabilizing parachute opens the pack.

[0003] When a skydiver uses the parachute opener for a second-stage parachute opening, the stabilizing chute engages after the skydiver exits the aircraft, and the mechanical automatic opener releases the stabilizing chute's release lock. In my country's current integrated main and reserve parachute packs, the harness straps all use a three-ring release lock to secure the stabilizing chute, located between the main and reserve parachute packs.

[0004] This structure results in poor parachute integration. When the stabilizing parachute is in operation, the middle part of the parachute is lifted, causing the parachute to form an "arch" shape. This can easily lead to malfunctions such as the release lock being pressed down by the parachute and unable to disengage, or the release lock deflecting and causing premature release. When the three-ring device is installed at the tail of the parachute, the suspension point of this structure is too low. Parachutists need to spread their limbs to maintain balance in the air. If the posture is not maintained correctly, the stabilizing parachute may become entangled in the legs, causing injury. This requires a high level of parachuting skill and is not suitable for large-scale group parachute jumps.

[0005] When skydivers use the existing integrated main and backup parachute pack harness system for two-stage parachute deployment training, the stabilizing parachute release lock is located between the main parachute pack and the backup parachute pack. This structure results in poor pack integration. When the stabilizing parachute is in operation, the middle part of the pack is lifted, which can easily cause the release lock to be pressed down by the pack and unable to release, or the release lock to deflect and release prematurely. Summary of the Invention

[0006] The purpose of this invention is to provide a cone-shaped sealing and disengagement mechanism to solve the problem of parachute integration and improve system reliability.

[0007] The technical solution to achieve the purpose of this invention is as follows: a cone-shaped sealing and releasing mechanism, including a cone, a connecting belt, a cone protective sleeve, and a safety pin; the connecting belt passes through the cone and is fixed by a cone fixing pin and a cone fixing pin screw; a safety pin is provided on the connecting belt, and the sealing is performed using the safety pin on the connecting belt.

[0008] The cone disc body is an integrated structure with upper and lower discs of different sizes. The two discs are connected in the middle and have a through hole in the middle. Two symmetrical circular holes are provided on the side of the middle disc for the cone disc fixing pin. The cone disc protective sleeve is fitted onto the large disc of the cone disc body.

[0009] A loop is sewn in the middle of the connecting band, and a safety pin is sewn at a certain distance above the loop. The connecting band passes through the through hole on the cone disc body. The cone disc fixing pin passes through the round hole on the upper side of the cone disc body and the loop in the middle of the connecting band, and then the cone disc fixing pin is fixed with a cone disc fixing pin screw.

[0010] The connecting strip has knots at both ends, which can be connected to other devices.

[0011] Compared with the prior art, the present invention has the following significant advantages: the cone-shaped structure of the present invention has its suspension point located above the parachutist's waist, which can maintain the body posture when exiting the aircraft in a small posture, and has a high consistency with the parachute training movements of active paratroopers. It solves the problem of parachute pack integration and improves the reliability of the system. Attached Figure Description

[0015] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0016] This invention relates to a cone-shaped blocking and disengagement mechanism for a stabilizing umbrella. See [link / reference]. Figure 2 The device mainly consists of a conical disc 1, a connecting belt 2, a conical disc protective sleeve 3, and a safety pin 4. The structure of the conical disc 1 is as follows: Figure 3As shown: It includes a conical disc body 5, a conical disc fixing pin 6, and a conical disc fixing pin screw 7; wherein, the conical disc body 5 is an integral structure, with the upper and lower parts being discs of different sizes, the two discs being connected together in the middle, and having a through hole with a diameter of 27mm in the middle. There are two symmetrical round holes on the side of the middle of the disc for the conical disc fixing pin 6 to pass through; a loop is sewn in the middle of the connecting band 2, and a safety pin 4 is sewn 10cm above the loop. The connecting band 2 passes through the through hole on the conical disc body 5, and the conical disc fixing pin 6 passes through the round hole on the upper side of the conical disc body 5 and the loop in the middle of the connecting band 2. Then, the conical disc fixing pin 6 is fixed with the conical disc fixing pin screw 7. There are knots at both the upper and lower ends of the connecting band 2, which can be connected to other devices. Use the sealing loop to pass through the sealing ring in a clockwise direction, and finally pass out from the eyelet body. There is a safety pin 4 on the connecting strap 2. When the immediate opening method is used, the safety pin 4 on the connecting strap is used to lock it; when the two-stage opening method is used, the pin of the mechanical opening device is used to lock it.

[0017] The main working process of the stabilizing parachute disengaging from the lock is as follows:

[0018] (1) Assemble the stabilizer parachute and release the lock.

[0019] Pass the connecting strap 2 through the round hole in the center of the cone disc body 5. The safety pin 4 of the connecting strap 2 is above the cone disc 1. Pass the cone disc fixing pin 6 through the round hole on the side of the cone disc body 5. When passing through the round hole in the center of the cone disc body 5, pass through the loop of the connecting strap 2. Finally, use a wrench to fix the cone disc fixing pin screw 7 and the cone disc fixing pin 6 to the cone disc body.

[0020] (2) Use a stabilizing umbrella to disengage the lock and seal.

[0021] In use, connect the connecting strap 2 and the main parachute canopy together. Place the main parachute canopy inside the main parachute pack. Place the cone 1 on top of the canopy. Wrap the main parachute packing loop around the cone 1 once to secure the four protective fabric panels of the main parachute pack. Secure the pack with the safety pin 4. After the stabilizing parachute is in operation, the opening dynamic load of the stabilizing parachute is transmitted to the four protective fabric panels of the main parachute pack through the cone 1. When the stabilizing parachute detaches, the main parachute packing opens, the cone 1 and the main parachute canopy are lifted sequentially, and then the main parachute is pulled out.

[0022] Compared to previous stabilized parachutes with release locks, the cone-shaped structure has its suspension point located above the parachutist's waist, allowing them to maintain their body posture even when exiting the aircraft in a small posture, and maintaining a high degree of consistency with the parachute training movements of active-duty paratroopers.

[0023] This invention has undergone nearly 30 ground and air tests. The test results show that the cone-shaped release mechanism works normally, is structurally stable and reliable, and the cone structure's suspension point is located above the parachutist's waist, allowing them to maintain their body posture even when exiting the aircraft in a small posture. This demonstrates a high degree of consistency with the parachute training movements of active-duty paratroopers, and the test results achieve the expected design effect. The invention has been verified as feasible and achieves its design objectives.
