Description

Technical Field

The steel needle pulling rocker arm is in contact and connection with the return rocker arm and the return stop rocker arm under the action of the torsion spring and the rotating shaft. With the conventional parachute pack pin insertion mechanism, since the steel wire rope is too long, its position cannot be fixed. When the parachute cabin shrinks, the steel wire rope gradually shrinks and bends from a straight state. Since the position of the steel wire rope cannot be fixed, the steel wire rope may be entangled in other parts of the aircraft, which is prone to failure. Therefore, in view of the problem that the steel wire rope gradually shrinks and bends from a straight state and is easy to be entangled, the conventional parachute pack pin insertion mechanism needs to be improved to meet the use requirements.

Example 2

[0032] like Figure 8 As shown, this embodiment is based on the embodiment 1. In order to facilitate the installation of the slide 1 in the parachute cabin, the pin mechanism described in this embodiment is adopted, and a mounting shaft 8 is also provided on the slide 1. The mounting shaft 8 is arranged on the slide 1 close to the side of the shaft cover 11. Through the arranged mounting shaft 8, the slide 1 can be conveniently installed on the body support in the parachute cabin.

[0033] The pin insertion mechanism for an umbrella bag of the present invention is used. In a specific application process, the pin insertion mechanism is installed in the umbrella cabin. The specific control process is that the slide 1 is installed on the body support in the umbrella cabin through the installation shaft 8 at the left end. When the umbrella cabin is in the closed state, the pin insertion mechanism is in the initial position. Its initial state structure is as follows: Figure 4 shown.

[0034] During the lifting process of the parachute cabin, the earring bolt 3 is driven to lift upward, and at the same time, the earring slide bar 2, the wire rope assembly 6 and the pull rod 4 are driven to slide out along the axis of the slide tube 1, and the slide tube 1 is driven to rotate around the body support. At this time, the limit handle 52 in the limit mechanism 5 slides relatively on the outer cylindrical surface of the earring slide bar 2; during the continued lifting of the parachute cabin, under the action of the torsion spring 53, the limit handle 52 rotates downward, passes through the limit groove 12 in the slide tube 1, and contacts the outer cylindrical surface of the pull rod 4 located inside the slide tube 1; during the continued lifting of the parachute cabin, the limit handle 52 contacts and connects with the stop boss in the limit part 41 at the front end of the pull rod 4, and the stop boss is used to restrict it from continuing to slide. At this time, the state of the pin mechanism is as follows: Figure 5 shown.

[0035] In this state, the locating pin 71 in the locating mechanism 7 and the wire rope joint 64 in the wire rope assembly 6 are limited by the locating portion in the locating pin 71 and the locating groove 65 in the wire rope joint 64. When the pull rod 4 continues to move backward, the wire rope joint 64 in the wire rope assembly 6 presses the locating pin 71, thereby compressing the spring 72, so that the earring slide bar 2 is separated from the pull rod 4 and the wire rope assembly 6, and the umbrella tube in the parachute cabin drives the earring slide bar 2 to continue to slide upward, thereby increasing the distance between the wire rope assembly 6 and the parachute bag, tightening the wire rope 61, and starting to pull out the pin 62 connected to the parachute bag. When the parachute cabin rises to the highest position, the distance between the wire rope assembly 6 and the parachute bag where the pin is to be inserted increases, and the pin 62 can be completely pulled out of the parachute bag by utilizing this distance difference. At this time, the state of the pin insertion mechanism is as follows: Figure 6 shown.

[0036] When the parachute compartment is in the fully opened state, the limit handle 52 in the limit mechanism 5 is pressed to separate the limit handle 52 from the stop boss in the limit portion 41 at the front end of the pull rod 4, and the insertion pin 62 is pulled outward to drive the pull rod 4 to slide upward. When the positioning pin 71 falls back to the positioning groove 65, the insertion pin 62 can be reinserted into the parachute bag. At this time, the state of the pin mechanism is as follows: Figure 7 shown.

[0037] When the parachute cabin retracts, it drives the earring slide bar 2, the pull rod 4 and the wire rope assembly 6 to slide down along the axis of the slide tube 1. When the outer cylindrical surface of the earring slide bar 2 hits the limit handle 52 in the limit mechanism 5, the limit handle 52 automatically lifts up and falls onto the outer cylindrical surface of the earring slide bar 2, and the parachute cabin continues to retract downward until it returns to the initial state.

[0038] It can be seen that the pin insertion mechanism for an umbrella bag described in the present invention is adopted. Since an earring slide rod 2 is provided in the slide tube 1, and a pull rod 4 connected to a wire rope assembly 6 is provided in the earring slide rod 2, the wire rope assembly 6 includes a wire rope 61, an insertion pin 62, a cylindrical pin 63 and a wire rope joint 64. The front end of the pull rod 4 is slidably connected to the inner wall surface of the slide tube 1, and the rear end thereof is connected to the wire rope 61 through the wire rope joint 64. Through the configured limiting mechanism 5 and positioning mechanism 7, the limiting mechanism 5 is contacted and connected with the limiting portion 41 in the pull rod 4 to limit the pull rod 4, and the positioning mechanism 7 is used to limit the wire rope joint 64 connected to the pull rod 4. A double limiting method is adopted, which can improve its safety performance.

[0039] In summary, by adopting the pin mechanism described in the present invention and applying it to a parachute cabin, the problem of the steel wire rope gradually shrinking, bending and becoming easily entangled from a straight state can be effectively solved when the parachute cabin is retracted, thereby greatly reducing safety hazards and meeting the use requirements of a parachute bag. The overall structure is simple, and the assembly is convenient, making it suitable for promotion and application.

[0040] Other aspects of the present invention that are not described in detail are all conventional techniques known to those skilled in the art.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various changes and variations may occur. Any modifications, equivalent substitutions, improvements, etc. made using the present invention should be included in the scope of protection of the present invention.
