In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] Such as Figures 1 to 9As shown in the figure, this embodiment provides a quick-opening cover device for protecting a pyrotechnic device socket. The quick-opening cover device for protecting a pyrotechnic device socket includes a main body 1, a top cover 2, and a switch lock 3. The main body 1 is detachably connected to the cabin wall of the aircraft. A receiving groove 10 is provided on the main body 1. A test socket 100 and a working socket 200 are arranged in the receiving groove 10. The top cover 2 is elastically reset and rotatably connected to the main body 1. The top cover 2 has an open position and a closed position. When the top cover 2 is in the open position, the notch of the receiving groove 10 is in a non-closed state. When the top cover 2 is in the closed position, the notch of the receiving groove 10 is closed. The switch lock 3 is elastically connected to the main body 1. The switch lock 3 has a locking position and an unlocking position. The switch lock 3 has a tendency to move from the unlocking position to the locking position and can be forced to move from the locking position to the unlocking position. When the switch lock 3 is in the locking position, it is limit-connected to the top cover 2 to limit the top cover 2 in the closed position. When the switch lock 3 is in the unlocking position, it is away from the top cover 2, and the top cover 2 is reset to the open position. By providing the receiving groove 10 and the top cover 2 that can close the notch of the receiving groove 10, the protection of the test socket 100 and the working socket 200 is realized, and the aerodynamic shape of the aircraft is maintained. At the same time, by operating the switch lock 3, the quick switching of the top cover 2 between the open position and the closed position can be realized, the quick switching of the test plug and the working plug can be realized, the operation efficiency is improved, and the operation time is saved. When testing is required, a force is applied to the switch lock 3. The switch lock 3 moves from the locking position to the unlocking position, and the top cover 2 is released. The top cover 2 is elastically reset to the open position. At this time, the notch of the receiving groove 10 is in an open state, and the test plug can be connected for testing. After the test is completed, the top cover 2 is switched to the closed position, and the switch lock 3 is used to limit-connect the top cover 2 so that the top cover 2 is limited in the closed position. Before work, open the top cover 2 in the same way as above and connect the working plug.

[0042] Preferably, a limiting step is circumferentially arranged along the circumference of the receiving groove 10 in the receiving groove 10. When the top cover 2 is in the closed position, it abuts against the limiting step, and the outer surface of the top cover 2 is flush with the notch of the receiving groove 10. The limiting step plays a certain role in supporting and limiting the top cover 2, so that after the switch lock 3 is limit-connected to the top cover 2, the top cover 2 is stable on the limiting step. Under the limiting action of the limiting step, it can effectively prevent the top cover 2 from being forced to rotate further into the receiving groove 10. At the same time, it is ensured that the outer surface of the top cover 2 is flush with the notch of the receiving groove 10, ensuring the flatness of the outer shape of the cover device. More preferably, a sealing ring is attached to the limiting step. When the top cover 2 is in the closed position, it abuts against the sealing ring. By providing the sealing ring, it is ensured that the space in the receiving groove 10 is sealed when the top cover 2 is in the closed position, preventing liquids such as water from flowing into the receiving groove 10 and affecting the test socket 100 and the working socket 200.

[0043] In this embodiment, the body includes a base 11 and a bottom plate 12. A through groove is formed in the base 11 along the thickness direction of the base 11. The bottom plate 12 is connected to one side of the base 11 and closes one end of the through groove to form a receiving groove 10. An installation opening 60 communicating with the receiving groove 10 is formed in the bottom plate 12. The installation opening 60 is used to install a test socket 100 and a working socket 200. Among them, the specifications of the installation opening 60 are set according to the required socket models to adapt to different sockets. Preferably, the bottom plate 12 is detachably connected to the base, for example, detachably connected by bolts, etc., which is convenient for replacing the bottom plate 12 with different specifications of the installation opening 60 and improves the practicability of the cover device.

[0044] Preferably, a plurality of connection holes are provided on the base 11. The body is detachably connected to the aircraft by connecting the connection holes and the bulkhead with bolts. Exemplarily, one or more connection holes are respectively provided at the four corners of the base 11.

[0045] Specifically, as Figure 3 , Figure 4 , Figures 7 to 9 shown, the cover device further includes a rotating shaft 4, a rotating pin 5 and a torsion spring 6. The rotating pin 5 is rotatably arranged on the main body 1. One end of the rotating shaft 4 is connected to the rotating pin 5, and the top cover 2 is fixed to the other end of the rotating shaft 4. The torsion spring 6 is sleeved on the rotating pin 5, and one end of the torsion spring 6 is connected to the main body 1 and the other end is connected to the rotating pin 5. By providing elastic force through the torsion spring 6, the rotating pin 5 has a tendency to rotate in one direction, that is, the top cover 2 fixed to the other end of the rotating shaft 4 has a tendency of automatic reset. That is, when the switch lock 3 moves to the unlocking position, the top cover 2 automatically rebounds to the open position under the reset action of the torsion spring 6, realizing the quick opening of the top cover 2. And the above structure is simple, with low cost and easy to produce.

[0046] In this embodiment, an installation cavity 20 communicating with one side of the receiving groove 10 is arranged in the main body 1. The rotating pin 5 is located in the installation cavity 20. One end of the rotating shaft 4 is connected to the rotating pin 5, and the other end extends out of the notch of the receiving groove 10. That is, the rotating pin 5, the rotating shaft 4, etc. are hidden in the installation cavity 20, making the outer surface of the main body 1 relatively regular and flat, and the structural compactness is better. Specifically, the rotating pin 5 is connected in the installation cavity 20 through a mounting seat 7. The mounting seat 7 is detachably connected to the cavity wall of the installation cavity 20, for example, detachably connected by bolts. A rotating hole is provided on the mounting seat 7. The rotating pin 5 is rotatably connected to the rotating hole. One end of the rotating shaft 4 is connected to the rotating pin 5 and can rotate synchronously with the rotating pin 5. Among them, the torsion spring 6 can be selected as a single torsion spring or a double torsion spring, which is not limited here.

[0047] Exemplarily, the installation cavity 20 and the receiving groove 10 are separated by a partition with a notch. The installation cavity 20 communicates with the receiving groove 10 through the notch. The rotating shaft 4 passes through the notch and extends out of the notch of the receiving groove 10.

[0048] More specifically, the rotating shaft 4 includes a swing arm section 41, an arc section 42, and a support section 43 arranged in sequence. The swing arm section 41 is connected to the rotating pin 5, and the top cover 2 is fixed on the support section 43. When the top cover 2 is in the open position, the swing arm section 41 abuts against the cavity wall of the installation cavity 20, that is, against the upper port edge of the notch. Here, the upper end refers to the end close to the notch of the receiving groove 10. That is, when the top cover 2 is in the closed position, the rotating shaft 4 is located in the installation cavity 20 and the receiving groove 10, ensuring the smoothness of the external structure of the cover device, thereby maintaining the aerodynamic shape of the aircraft. When the switch lock 3 is in the unlocked position, the top cover 2 is automatically bounced up by the torsion spring 6 and reset to the open position. During the bouncing process, the rotating shaft 4 rotates with the rotating pin 5, and the arc section 42 rotates along the side of the notch of the receiving groove 10 close to the installation cavity 20 until the swing arm section 41 abuts against the upper port edge of the notch. The setting of the arc section 42 makes the occupied space of the rotation path of the rotating shaft 4 smaller, avoiding interference with the test socket 100 and the working socket 200 in the receiving groove 10. The support section 43 is a flat plate, and the top cover 2 is attached to the support section 43, making the connection between the top cover 2 and the support section 43 reliable and stable.

[0049] Preferably, the upper port edge of the notch and the abutting portion of the swing arm section 41 are arranged in an inclined plane, so that a sliding pair is formed when the swing arm section 41 abuts against the upper port edge of the notch, increasing the contact area, avoiding damage to the swing arm section 41, and prolonging the service life of the rotating shaft 4.

[0050] Furthermore, as Figures 5 to 8 shown, the cover device further includes an elastic member 8. The switch lock 3 includes a swing plate 31 and a pressing plate 32. One end of the swing plate 31 is rotatably connected to the main body 1, and the other end is connected to the pressing plate 32. The elastic member 8 is connected between the pressing plate 32 and the main body 1. A locking hook head 33 is arranged on one side of the swing plate 31. Under the elastic force of the elastic member 8, when the top cover 2 is in the closed position, the locking hook head 33 hooks the top cover 2, and the pressing plate 32 can drive the swing plate 31 to rotate by force and drive the locking hook head 33 to disengage from the top cover 2. By setting the elastic member 8, the locking hook head 33 automatically locks the top cover 2, and when it is necessary to open the top cover 2, applying force to the pressing plate 32 can make the locking hook release the top cover 2, and the top cover 2 automatically resets to the open position, which is fast and convenient, conducive to saving operation time and improving operation efficiency.

[0051] Exemplarily, the elastic member 8 is a compression spring, and the compression spring and the lock hook head 33 are respectively located on both sides of the swing plate 31. Under the elastic force of the compression spring, the end of the pressing plate 32 connected to the compression spring always has a tendency to tilt up, that is, the swing plate 31 has a tendency to rotate away from the side of the compression spring, driving the lock hook head 33 to always have a downward tendency. When the top cover 2 is in the closed position, the lock hook head 33 can press the top cover 2 so that the top cover 2 is stable in the closed position; when the pressing plate 32 is pressed, the compression spring is compressed, and the end of the pressing plate 32 connected to the compression spring is pressed downward, that is, the swing plate 31 has a tendency to rotate toward the side of the compression spring, driving the lock hook head 33 upward away from the top cover 2 to achieve unlocking. Of course, the elastic member 8 can also be a tension spring. The tension spring and the lock hook head 33 are located on the same side of the swing plate 31. Under the elastic force of the tension spring, the lock hook head 33 has a tendency to press downward, pressing the pressing plate 32 to overcome the elastic force of the tension spring, so that the lock hook head 33 is tilted up, that is, away from the top cover 2, to achieve unlocking.

[0052] Preferably, the main body 1 is provided with a first mounting groove 40 and a second mounting groove 50, the swing plate 31 is rotatably connected in the first mounting groove 40 through a pin, and part of the elastic member 8 is located in the second mounting groove 50. The provision of the first mounting groove 40 and the second mounting groove 50 makes the appearance of the cover device relatively smooth and smooth, and also provides a protective effect on the switch lock 3. In this embodiment, the main body 1 is provided with a mounting groove, and the first mounting groove 40 and the second mounting groove 50 are formed in the first mounting groove 40. When the switch lock 3 is in the locked position, the upper surface of the pressing plate 32 is flush with the notch of the mounting groove, thereby ensuring the flatness of the appearance of the cover device. More preferably, the mounting groove and the mounting cavity 20 are respectively located on opposite sides of the receiving groove 10, that is, one side of the top cover 2 is connected to the rotating shaft 4, and the opposite side can be connected to the switch lock 3 in a limiting manner, so that the limiting effect of the switch lock 3 on the top cover 2 is relatively reliable and stable. Of course, in other embodiments, the mounting groove and the mounting cavity 20 can also be respectively located on the adjacent two sides of the receiving groove 10, which is specifically set according to actual needs.

[0053] Specifically, the switch lock 3 further includes an elastic sheet 34, one end of which is connected to one end of the swing plate 31 away from the pressing plate 32 and forms a U-shaped structure with the swing plate 31, and the other end of the elastic sheet 34 extends in a direction away from the swing plate 31 to form a lock hook head 33. Due to its own structural characteristics and the U-shape of the elastic sheet 34 and the swing plate 31, when the lock hook head 33 is connected to the top cover 2, the lock hook head 33 and the top cover 2 are non-rigidly connected, which is conducive to extending the service life of the top cover 2 and the switch lock 3. At the same time, when the top cover 2 is closed, the top cover 2 is pressed, and the side of the top cover 2 can push the lock hook head 33, and the elastic sheet 34 swings toward the swing plate 31 until the lock hook head 33 is connected to the top cover 2 in a limited position.

[0054] Preferably, a locking groove 30 is formed on one side of the top cover 2. When the top cover 2 is in the closed position, the locking hook head 33 hooks the locking groove 30. That is, after the switch lock 3 is connected to the top cover 2 in a limiting manner, the outer surface of the cover device is relatively flush, and the connection part between the switch lock 3 and the top cover 2 is not easily affected by external objects, and the connection stability is relatively good.

[0055] Exemplarily, the thickness of the top cover 2 is limited. In order not to affect the connection stability between the locking hook head 33 and the top cover 2, the locking groove 30 penetrates the inner side surface of the top cover 2, where the inner side surface refers to the side surface close to the receiving groove 10. A locking plate 9 is provided on the inner side surface of the top cover 2 opposite to the locking groove 30. The locking hook head 33 is located in the locking groove 30 and abuts against the locking plate 9, that is, the locking hook head 33 presses the top cover 2 by pressing the locking plate 9. Preferably, an avoidance groove is formed on the limiting step. When the top cover 2 is in the closed position, the locking plate 9 is located in the avoidance groove to ensure the flushness of the top cover 2 and the notch of the receiving groove 10.

[0056] Preferably, the locking hook head 33 and the elastic piece 34 are arranged at an acute angle, such as 84°-87°. The contact surface between the locking plate 9 and the locking hook head 33 is also arranged as an inclined surface, so that the locking hook head 33 can stably hook the locking plate 9 and press the top cover 2 tightly.

[0057] In another embodiment, the switch lock 3 can also be of other structures. For example, the switch lock 3 includes a locking pin, and the locking pin is elastically connected to the main body 1 along a first direction, where the plane where the first direction is located is the plane where the top cover 2 is located in the closed position. A locking groove 30 is provided on one side of the top cover 2. For example, the locking pin is elastically connected to the main body 1 through a compression spring. Under the elastic force of the compression spring, the locking pin automatically inserts into the locking groove 30 to lock the top cover 2; when it is necessary to open the top cover 2, apply force to the locking pin to make the compression spring contract, and the locking pin retreats from the locking groove 30 to achieve unlocking.

[0058] The following is the usage process of the quick-opening cover device for the protection of the initiator socket:

[0059] When a test is required, press the pressing plate 32, and the locking hook head 33 disengages from the top cover 2. The top cover 2 automatically rotates to the open position under the action of the torsion spring 6, and the test plug can be inserted to start the test;
