A sliding gas interlock

Abstract

This invention provides a sliding gas interlock device, comprising two inlet connectors, a housing, an outlet connector, a slider, a locking tongue, and a spring. The housing is provided with connecting parts for the inlet connectors, outlet connectors, and screw caps, as well as a sliding channel and an outlet channel for the slider to move. The two inlet connectors are connected to both ends of the housing, providing inlet channels. The outlet connector is connected to the housing, providing an outlet channel. The slider is provided with two limiting grooves and is installed inside the housing. One end of the locking tongue is connected to one end of the spring, and the other end presses against the slider. When the slider slides along the sliding channel under the action of gas, the locking tongue engages with either limiting groove on the slider to lock, allowing the gas outlet channel to connect with the outlet channel of the outlet connector. This invention achieves gas interlocking between the cap-throwing system and the ejection start system by ensuring gas input from both sides through the sliding channel, thus solving the problems of complex structure and poor maintainability of mechanical locking systems.

Description

Technical Field

[0001] This invention belongs to the field of aircraft lifesaving and relates to a sliding gas interlock device. Background Technology

[0002] In an emergency, when a pilot ejects, it is necessary to ensure that the canopy is jettisoned and the ejection seat is activated before the pilot can eject from the aircraft. Therefore, the canopy jettisoning system and the ejection activation system need to be interlocked to ensure safe ejection. Existing mechanical interlocking devices rely on mechanical pins, and their internal spring structures require regular inspection and maintenance. They are complex in structure and have poor maintainability. Summary of the Invention

[0003] Purpose of the invention: To provide a sliding gas interlocking device that can interlock the cabin canopy jettisoning system with the ejection system. This interlocking device has a simple structure and reliable operation.

[0004] Invention technical solution: A sliding gas interlock device includes two inlet connectors, a housing, an outlet connector, a slider, a locking tongue, and a spring. The housing is provided with connecting parts for the inlet connectors, outlet connectors, and screw caps, as well as a sliding channel and an outlet channel for the slider to move. The two inlet connectors are connected to both ends of the housing to provide inlet channels. The outlet connector is connected to the housing to provide an outlet channel. The slider is provided with two limiting grooves and is installed inside the housing. One end of the locking tongue is connected to one end of the spring, and the other end presses against the slider. When the slider slides along the sliding channel under the action of gas, the locking tongue engages with any of the limiting grooves on the slider to lock, allowing the gas outlet channel to be connected to the outlet channel of the outlet connector.

[0005] In the above scheme, the length of the slider's sliding direction and the distance between the two limiting grooves are adapted to the air outlet channel C set in the air outlet connector, so that the air outlet channel formed when the slider slides to the left or right is connected to the air outlet channel C.

[0006] In the above scheme, after gas is input into both intake channel A and intake channel B, when gas enters intake channel A first, the slider slides along the sliding channel so that the locking tongue cooperates with the limiting groove on the left side of the slider to lock it. The gas outlet channel on the left side is connected to the outlet channel C on the outlet connector, and the gas is output from the outlet channel C.

[0007] In the above scheme, after gas is input into both intake channel A and intake channel B, when gas enters intake channel B first, the slider slides along the sliding channel so that the locking tongue cooperates with the limiting groove on the right side of the slider to lock it. The gas outlet channel on the right side is connected to the outlet channel C on the outlet connector, and the gas is output from the outlet channel C.

[0008] In the above scheme, the gas interlock device also includes a positioning pin, one end of which is connected to the slider and the other end to the locking tongue, so that the slider is initially positioned and can be sheared during sliding. Both the inlet and outlet connectors include sealing structures to ensure their airtightness.

[0009] In the above scheme, the sealing structure is a sealing ring type or a flared pipe connection type.

[0010] In the above scheme, both the air inlet connector and the air outlet connector include a fixed structure.

[0011] In the above scheme, the slider includes air inlet channels and air outlet channels on both sides.

[0012] In the above scheme, the gas interlock device also includes a screw cap, which is threadedly connected to the housing, and one end of the screw cap is connected to the other end of the spring to form a sealed space.

[0013] The advantages and beneficial effects of this invention are as follows: It proposes a sliding gas interlocking device, which allows gas to be output only after gas is input from both sides through a sliding channel, realizing the gas interlock between the cover throwing system and the ejection start system. It solves the problems of complex structure and poor maintainability of mechanical locking devices, and is also convenient to implement, widely adaptable, and easy to use and maintain.

[0020] The present invention will be further described in detail below through specific embodiments:

[0021] The present invention will now be described in further detail. See below. Figure 1 A sliding gas interlock device consists of two inlet connectors 1, a housing 2, an outlet connector 3, a slider 4, a positioning pin 5, a locking tongue 6, a spring 7, and a screw cap 8. The inlet connector 1 is connected to the housing 2 to provide an inlet channel. The outlet connector 3 is connected to the housing 1 to provide an outlet channel. The slider 4 is installed inside the housing 2. One end of the positioning pin 5 is connected to the slider 4, and the other end is connected to the locking tongue 6. One end of the locking tongue 6 is connected to the spring 7, and the other end is pressed against the slider 4.

[0022] The air intake connector 1 includes a sealing structure and a fixing structure. The sealing structure can be a sealing ring type or a flared pipe connection type. It provides a gas intake passage by connecting with the housing 2.

[0023] The gas outlet connector 3 includes a sealing structure and a fixing structure. The sealing structure can be a sealing ring type or a flared pipe connection type. The gas outlet connector can output gas from either side of the gas inlet through a single interface.

[0024] The housing 2 provides connection positions for the air inlet connector 1, the air outlet connector 3, and the screw cap 8, and also provides sliding space and air outlet channel for the slider 4;

[0025] The slider 4 includes air inlet channels and air outlet channels on both sides. When the sliding channel slides to the end position, it can lock the gas channel on one side and release the gas channel on the other side.

[0026] The positioning pin 5 is a positioning device that can be cut during movement. Before the slider 4 can slide, the positioning pin 5 needs to be cut before it can slide to one side.

[0027] The locking tongue 6 engages with the limiting groove on the slider 4 to limit the slider 4; when the slider 4 moves to the end position, the locking tongue engages with the limiting groove on it to lock the sliding channel.

[0028] The gas interlock device provided by this invention can only output gas from the outlet channel C if both the intake channels A and B on both sides have gas. Gas output can be achieved by inputting gas into either channel first. Figure 2 The size L1 is the same. Figure 3 With the same size L2, the gas can be output after the sliding channel slides. For example... Figure 4 As shown, after the slider 4 slides to the left, the gas output on the right side increases. Figure 5 As shown, after the slider 4 slides to the right, the gas output on the left side is activated.
