Description

Technical Field

[0001] The invention belongs to the technical field of parachutes, and in particular, relates to a device suitable for opening a parachute in linkage with a main parachute and a standby parachute. Background Art

[0002] In the event that the main parachute does not open in the air or cannot be inflated normally after opening, it is necessary to fly off the main parachute and open the backup parachute. When a skydiver handles an emergency situation with the main parachute in the air, he or she will first fly off the main parachute and then open the backup parachute bag to release the backup parachute. This way of handling special situations requires strict adherence to the operating sequence, i.e. first pull the emergency parachute doffing wire rope - fly off the main parachute, then pull out the backup parachute hand ring - open the backup parachute bag and release the backup parachute. This handling method not only has a greater possibility of misoperation, but also consumes a greater safe parachute opening altitude in the air. When the above emergency occurs, the emergency operation sequence is as follows Figure 1 .

[0003] In the above emergency operation, the "emergency parachute handle" and "backup parachute hand ring" must be pulled off in sequence. Although these two emergency handles are arranged on the left and right main straps of the parachute bag straps, in the case of distress in the air, the parachutist's nerves are extremely tense and it is very easy to make mistakes. In addition, in the process of handling special situations in the normal order, the parachutist will consume part of the safe time and safe height of the parachute opening due to thinking and operation.

[0004] Therefore, it is necessary to add a linkage parachute opening mechanism. When the skydiver handles a special situation in the air, after pulling off the emergency parachute handle and flying off the main parachute, the backup parachute bag is opened and the backup parachute is released through the linkage parachute opening mechanism. Summary of the invention

[0005] The object of the present invention is to provide a device suitable for main and standby linkage parachute opening.

[0006] The technical solution to achieve the purpose of the present invention is: a device suitable for main and standby linkage parachute opening, including a main parachute control belt, a linkage belt and a backup parachute package pin, one end of the linkage belt is connected to the main parachute control belt, and the other end is connected to the backup parachute package pin.

[0007] Furthermore, the backup parachute package pin includes a fixing belt, a steel wire rope and a pin. The fixing belt fixes the entire backup parachute package pin on the parachute bag shoulder strap. The steel wire rope connects the fixing belt and the pin, and the pin closes the backup parachute bag.

[0008] Furthermore, the main parachute control belt includes a control belt main part and a connecting ring. The connecting ring is sewn to the bottom end of the control belt main part through webbing. The control belt main part is connected to the parachute rope upwards and to the parachute bag strap system downwards. The connecting ring is connected to the linkage belt.

[0009] Furthermore, the linkage belt comprises a spring buckle, a main part of the connection belt, a buckle belt and a ring, the spring buckle is connected to the main parachute control belt, and a pull tab is provided on the spring buckle, and the linkage belt can be removed from the control belt by pulling the pull tab;

[0010] The main part of the connecting belt connects the spring buckle and the ring, and the backup parachute closing pin first passes through the ring and then closes the backup parachute bag; the buckle belt is located on the main belt of the linkage belt, and there are 3 sections in total, one of which cooperates with the buckle belt on the parachute bag to fix the linkage belt, and the other two sections cooperate with each other to shorten the excess length of the linkage belt.

[0011] Compared with the prior art, the present invention has the following significant advantages: the device of the present invention can link the opening of the reserve parachute bag and release the reserve parachute while the main parachute is flying off; the operation is simple and convenient, and the safe parachute opening time and safe parachute opening height will not be lost.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] A main parachute-reserve parachute linkage opening device (hereinafter referred to as linkage opening device) of the present invention comprises a main parachute control belt 1, a linkage belt 2 and a backup parachute package pin 3. One end of the linkage belt 2 is connected to the main parachute control belt 1, and the other end is connected to the backup parachute package pin 3.

[0021] Its working principle is: when the skydiver pulls off the emergency parachute handle, the main parachute and the control belt are separated from the parachute bag strap, the linkage belt connected to the control belt is stressed and the backup parachute package pin is pulled out through the other end to open the backup parachute.

[0022] The linkage parachute opening device is composed of a main parachute control belt 1, a linkage belt 2 and a backup parachute package pin 3.

[0023] Combination Figure 2 The backup parachute package pin 3 includes a fixing belt 4, a wire rope 5 and a pin 6. The function of the fixing belt 4 is to fix the entire backup parachute package pin 3 on the parachute bag strap. The function of the wire rope 5 is to connect the fixing belt 4 and the pin 6. The function of the pin 6 is to close the backup parachute bag.

[0024] Combination Figure 3 The main parachute control belt 1 includes: a control belt main part 7 and a connecting ring 8, and the functions of each part are as follows:

[0025] 1) The main part of the control belt 7: connected to the parachute rope upwards and connected to the parachute bag harness system 13 downwards.

[0026] 2) Connecting ring 8: connects the linkage belt 2.

[0027] Combination Figure 4 The linkage belt 2 includes: a spring buckle 9, a connecting belt main part 10, a buckle belt 12 and a ring 11. The main functions of each part are as follows:

[0028] 1) Spring buckle 9: Its function is to connect the operating belt 1. There is a pull tab on the spring buckle 9, and the linkage belt 2 can be removed from the operating belt by pulling the pull tab.

[0029] 2) Linkage belt main part 10: As the main force-bearing component in the process of linkage opening, it connects the spring buckle 9 and the ring 11 and transmits the pulling force in the process of linkage opening.

[0030] 3) Ring 11: The sealing pin 3 of the reserve parachute will first pass through the ring 11 and then close the reserve parachute bag. Its function is to pull the sealing pin 3 of the reserve parachute out of the sealing rope loop through the ring 11 when the linkage belt 2 is stressed, so as to achieve the purpose of opening the parachute.

[0031] 4) Buckle strap 12: The buckle strap has 3 sections in total, one of which cooperates with the buckle strap on the umbrella bag to fix the linkage belt, and the other two sections cooperate with each other to shorten the excess length of the linkage belt 2.

[0032] The coordination mode of the linkage parachute opening device is as follows:

[0033] 1) Assemble the control belt 1 with the parachute rope and parachute bag harness system (see Figure 5 );

[0034] 2) One end of the linkage belt buckle 9 is assembled with the control belt connecting ring 8 (see Figure 6 ), one end of the linkage belt ring 11 is assembled with the backup parachute package pin 3 (see Figure 7 ).

[0035] The invention has been subjected to ground parachute opening simulation tests and aerial special situation tests (opening the backup parachute in linkage with the main parachute when it flies off). The ground test and aerial test results show that the invention can open the backup parachute bag in linkage with the main parachute when it flies off and release the backup parachute.
