Description

Technical Field

[0001] This invention relates to a lock and a locking device for a fairing, belonging to the field of fairing technology. Background Technology

[0002] The fairing is a crucial component of a helicopter. To facilitate the maintenance of the helicopter's power system and ensure the connection strength and aerodynamic shape between the fairing and the fuselage structure, the fairing lock is an indispensable part, used to lock and open the fairing. Fairings generally employ a rotating design, meaning the fairing opens or closes by rotating. They typically consist of left and right movable fairings, with the lock body and lock seat of the fairing lock mounted on the left and right movable fairings respectively.

[0003] Existing fairing locks generally use a movable key, which is moved towards the movable cover where the lock base is located to unlock. However, this method causes the key to move into the path of the movable cover after the fairing lock is unlocked, thus creating an obstruction. This means that the movable cover connected to the key must be opened first when opening the fairing, which restricts the opening sequence of the left and right movable covers and makes the fairing opening inconvenient.

[0004] Therefore, in order to open the fairing more easily, a new, optimized fairing locking device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a lock that can more easily open the fairing and a locking device for the fairing.

[0006] This invention provides a lock, disposed within a fairing locking device, for locking two movable covers of the fairing together, and characterized by comprising:

[0007] Locking assembly, for mounting on the first movable cover of the fairing, includes a locking pin; and

[0008] The lock assembly, for mounting on the second movable cover of the fairing, includes a locking lever, a moving part, and a resilient abutment.

[0009] One end of the locking rod extends radially outward from the locking pin, and this end is bent toward the side where the locking pin is located to form a locking hook portion for engaging with the locking pin; the other end is rotatably mounted on the movable member.

[0010] The movable member can move between a first position and a second position. In the first position, the locking hook engages with the locking pin to form a locking fit, and the locking rod abuts against the circumferential surface of the locking pin. In the second position, the locking hook disengages from the locking pin, and the locking rod is raised at a certain angle relative to the locking pin.

[0011] The elastic abutment member has an abutment portion that abuts against the side surface of the locking rod facing away from the locking pin.

[0012] The locking rod has a mating part on the side that abuts against the abutting part, which is used to drive the locking rod to rotate a certain angle toward the side away from or toward the locking pin during the movement of the moving part.

[0013] During the movement of the movable member from the first position to the second position, the locking hook gradually disengages from the locking pin. After disengagement, the engaging part reaches the abutting part and engages with it, thereby driving the locking rod to rotate a certain angle toward the side away from the locking pin.

[0014] During the movement of the movable member from the second position to the first position, the locking rod first rotates by the same angle toward the side closer to the locking pin, and then the locking hook gradually engages with the locking pin.

[0015] The lock provided by this invention may also have the following features:

[0016] The abutting part is a rod, and the mating part is a hook that matches the abutting part. The mating part and the abutting part are spaced apart from each other in the direction from the first position to the second position of the moving part.

[0017] When the mating part reaches the abutting part, the two engage, thereby driving the locking rod to rotate a certain angle toward the side away from or toward the locking pin during the movement of the moving part.

[0018] The lock provided by this invention may also have the following features:

[0019] The lock body assembly further includes a lock housing for connection to the second movable cover of the fairing, and has a channel portion open at least one end. The movable member is movably disposed within the channel portion. One end of the locking rod extends into the channel portion and is hinged to the end of the movable member, while the other end extends from the open end of the channel portion to the side where the locking pin is located.

[0020] The elastic abutment is disposed in the channel portion and includes an elastic member and an abutment member. The elastic member is used to give the abutment member a tendency to rotate toward the side closer to the locking rod. One end of the abutment member is rotatably mounted on the lock housing, and the other end forms the abutment portion.

[0021] The lock provided by this invention may also have the following features:

[0022] The lock seat assembly further includes a lock seat for connecting to the first movable cover of the fairing. The locking pin is fixedly disposed on the lock seat at one end facing the locking rod and forms a locking groove with the lock seat.

[0023] When in the first position, the end of the locking hook passes through the locking groove and engages with the locking pin.

[0024] The side wall of the latch groove opposite to the locking pin has a guide portion, which is used to collide with the locking hook portion during the movement of the moving member from the first position to the second position to guide the locking hook portion to slide out of the latch groove.

[0025] The lock provided by this invention may also have the following features, including:

[0026] A driving component for driving the movable member to move between the first position and the second position, comprising:

[0027] The first swing arm is rotatably mounted on the lock housing and has two swing ends; and

[0028] The connecting rod has one end hinged to the end of the moving member that is opposite to the locking rod, and the other end hinged to one swinging end of the first swing arm. The other swinging end of the first swing arm is used to connect to a drive source.

[0029] When the first swing arm rotates, the moving part is driven to move between the first position and the second position via the connecting rod.

[0030] This invention provides a locking device for a fairing, disposed inside the fairing, for unlocking or locking the fairing, and characterized by comprising:

[0031] Multiple locking devices are used to install at the joint between the first and second movable fairings of the fairing;

[0032] A linkage mechanism, connected to the drive of multiple locks, is used to achieve the coordinated unlocking or locking of the multiple locks; and

[0033] The operating mechanism, connected to the linkage mechanism, is used to provide power to the linkage mechanism.

[0034] The lock is the lock as described above.

[0035] The fairing locking device provided by the present invention may also have the following features:

[0036] The linkage mechanism includes multiple linkage rods. Two adjacent locks transmit power through one linkage rod. One end of the linkage rod is indirectly or directly connected to the moving part in one of the locks, and the other end is indirectly or directly connected to the moving part in the other lock.

[0037] The fairing locking device provided by the present invention may also have the following features:

[0038] The operating mechanism includes:

[0039] Handle plate for connecting to the second movable cover of the fairing;

[0040] A handle shaft rotatably passes through the handle disc;

[0041] An operating handle is fixedly mounted at the first end of the handle shaft;

[0042] The second swing arm is fixedly mounted at the second end of the handle shaft, and has two swing ends, one of which is drivenly connected to one of the linkage rods; and

[0043] A reset element, disposed on the handle disc and connected to another swing end of the second swing arm, is used to give the second swing arm a tendency to rotate in the locking direction.

[0044] Specifically, when the second swing arm rotates in the unlocking direction, it drives multiple movable parts within the lock to move from the first position to the second position via multiple linkage rods; when the second swing arm rotates in the locking direction, it drives multiple movable parts within the lock to move from the second position to the first position via multiple linkage rods.

[0045] The fairing locking device provided by the present invention may also have the following features:

[0046] The outer surface of the handle disc has a recessed handle groove. The first end of the handle shaft extends into the handle groove and is connected to the end of the operating handle via a connecting shaft. The operating handle can rotate around the connecting shaft between a third position and a fourth position.

[0047] The operating mechanism further includes a handle locking assembly for locking the operating handle in the handle groove when it is in the third position. A first torsion spring is sleeved on the connecting shaft for giving the operating handle a tendency to rotate toward the fourth position.

[0048] When in the third position, the operating handle is locked in the handle groove by the handle locking assembly. When in the fourth position, the operating handle is raised at a certain angle relative to the outer surface of the handle plate.

[0049] The fairing locking device provided by the present invention may also have the following features:

[0050] The handle locking component includes:

[0051] A lock hole is provided on the side of the operating handle;

[0052] A locking element, rotatably mounted on the handle disc, has a pressing portion and a locking key for insertion and removal into the lock hole; when the pressing portion is pressed, the locking element rotates in a first direction; and

[0053] A second torsion spring is used to cause the locking member to have a tendency to rotate in the opposite direction to the first direction.

[0054] When the operating handle is in the third position and the pressing part is pressed, the locking member rotates along the first direction, thereby causing the lock key to be pulled out of the keyhole. Then, the operating handle rotates to the fourth position under the action of the second torsion spring.

[0055] When the pressing part is no longer pressed, the locking member rotates in the opposite direction of the first direction to reset.

[0056] Therefore, the present invention has the following advantages compared with the prior art:

[0057] According to the lock and fairing locking device of the present invention, the fairing locking device includes multiple locks, a linkage mechanism, and an operating mechanism. Each lock includes a lock seat assembly and a lock body assembly. The lock seat includes a locking pin. The lock body assembly includes a locking rod, a moving member, and a resilient abutment member. One end of the locking rod extends radially outward from the locking pin and is bent towards the side where the locking pin is located to form a locking hook portion for engaging with the locking pin. The other end is rotatably mounted on the moving member, which can move between a first position and a second position. The resilient abutment member has an abutment portion, and the side of the locking rod that abuts the abutment portion has a mating portion. When the moving member moves from the first position to the second position, the moving member drives the locking rod to move synchronously, thereby causing the locking hook portion to gradually disengage from the locking pin. After the two parts disengage, the moving part continues to move to the second position. Under the action of the elastic abutment, the abutment part always abuts against the surface of the locking rod on the side opposite to the locking pin. This allows the mating part to engage with the abutment part when it reaches the abutment part, thereby driving the locking rod to rotate a certain angle away from the locking pin. When the moving part moves to the second position, the locking hook part disengages from the locking pin, and the locking rod is raised at a certain angle relative to the locking pin. This releases the lock on the two movable covers of the fairing, thus enabling the fairing to open. Furthermore, since the locking rod is raised at a certain angle relative to the locking pin after unlocking, it can make way for the movable cover where the locking pin is located, thus not restricting the opening sequence of the two movable covers, making the opening of the fairing more convenient.

Detailed Implementation

[0076] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the lock and fairing locking device of the present invention in detail with reference to the embodiments and accompanying drawings.

[0077] This embodiment provides a lock and a locking device for the fairing that can be opened more conveniently. The fairing is installed in a fairing with two movable fairings. The outer ends of the two movable fairings are respectively hinged to the fuselage of the helicopter, and the inner ends of the two movable fairings are connected to each other, so that the movable fairings can be rotated around the hinge point to open or close.

[0078] Figure 1 This is a three-dimensional structural schematic diagram of the locking device for the fairing in an embodiment of the present invention.

[0079] like Figure 1 As shown, the fairing locking device 100 of this embodiment includes multiple locks 10, a linkage mechanism 20, and an operating mechanism 30. The multiple locks 10 are installed at the joint between the first and second movable covers of the fairing, locking the free ends of the two movable covers together to achieve fairing locking. The multiple locks 10 are spaced apart at the joint to form multiple locking points, ensuring locking stability. The linkage mechanism 20 is driven by the multiple locks 10, enabling the linkage unlocking or locking of the multiple locks 10. The operating mechanism 30 is driven by the linkage mechanism 20, providing power to the linkage mechanism 20. Understandably, during use, the operator can apply power to the operating mechanism 30 to power the linkage mechanism 20, thereby enabling the linkage unlocking or locking of the multiple locks 10.

[0080] Figure 2 This is a three-dimensional structural diagram of the lock in an embodiment of the present invention; Figure 3 This is a cross-sectional structural diagram of the lock in an embodiment of the present invention.

[0081] like Figure 2 and Figure 3As shown, the lock 10 includes a lock seat assembly 11 and a lock body assembly 12. The lock seat assembly 11 is mounted on the first movable cover of the fairing and includes a locking pin 111. The lock body assembly 12 is mounted on the second movable cover of the fairing and includes a locking lever 121, a movable member 122, and a resilient abutment member 123. One end of the locking lever 121 extends radially outward from the locking pin 111 and is bent toward the side where the locking pin 111 is located to form a locking hook portion 121a for engaging with the locking pin 111. The other end is rotatably mounted on the movable member 122. The movable member 122 can move between a first position and a second position. In the first position, the locking hook portion 121a engages with the locking pin 111 to form a locking engagement, and the locking lever 121 abuts against the circumferential surface of the locking pin 111. In the second position, the locking hook portion 121a disengages from the locking pin 111, and the locking lever 121 is raised at a certain angle relative to the locking pin 111. The elastic abutment member 123 has an abutment portion 123a, which abuts against the side surface of the locking rod member 121 facing away from the locking pin 111. The side of the locking rod member 121 that abuts against the abutment portion 123a has a mating portion 121b, which is used to drive the locking rod member 121 to rotate a certain angle toward the side away from or toward the locking pin 111 during the movement of the moving member 122.

[0082] During the movement of the movable member 122 from the first position to the second position, the locking hook portion 121a gradually disengages from the locking pin 111. After the two disengage, the engaging portion 121b reaches the abutting portion 123a and engages with it, thereby driving the locking rod 121 to rotate a certain angle toward the side away from the locking pin 111. During the movement of the movable member 122 from the second position to the first position, the locking rod 121 first rotates the same angle toward the side closer to the locking pin 111, and then the locking hook portion 121a gradually engages with the locking pin 111.

[0083] Understandably, when the moving part 122 is in the first position, the locking hook 121a engages with the locking pin 111 to form a locking fit, thereby enabling the locking connection of the two movable covers of the fairing, thus achieving the locking of the fairing.

[0084] As the movable member 122 moves from the first position to the second position, it drives the locking rod 121 to move synchronously, causing the locking hook 121a to gradually disengage from the locking pin 111. After the two disengage, the movable member 122 continues to move to the second position. Under the action of the elastic abutment member 123, the abutment part 123a always abuts against the side surface of the locking rod 121 facing away from the locking pin 111, so that when the mating part 121b reaches the abutment part 123a, it can drive the locking rod 121 away from the locking pin 111. One side of 1 is rotated by a certain angle, so that when the moving part 122 moves to the second position, the locking hook part 121a disengages from the locking pin 111, and the locking rod 121 is raised at a certain angle relative to the locking pin 111. This releases the lock of the two movable covers of the fairing, thereby realizing the opening of the fairing. Furthermore, since the locking rod 121 is raised at a certain angle relative to the locking pin 111 after unlocking, the locking rod 121 can make way for the movable cover where the locking pin 111 is located, thus not restricting the opening sequence of the two movable covers, and making the opening of the fairing more convenient.

[0085] As the moving part 122 moves from the second position to the first position, the driving engagement of the abutment part 123a and the mating part 121b causes the locking rod 121 to first rotate towards the side closer to the locking pin 111 by the same angle, thereby causing the locking rod 121 to rotate back to the position where it abuts against the circumferential surface of the locking pin 111. After the locking rod 121 rotates to this position, the moving part 122 continues to move to the first position. During this process, the locking hook part 121a gradually engages with the locking pin 111, so that when the moving part 122 moves to the first position, the locking hook part 121a and the locking pin 111 are engaged to form a locking engagement, thereby locking the two movable covers of the fairing together and thus achieving the locking of the fairing.

[0086] Figure 4 This is a three-dimensional structural diagram of the lock body assembly in an embodiment of the present invention.

[0087] like Figure 4 As shown, the abutment part 123a is a rod, and the mating part 121b is a hook that matches the abutment part 123a. The mating part 121b and the abutment part 123a are spaced apart from each other in the direction from the first position to the second position of the moving member 122. When the two are engaged, the locking rod 121 is driven to rotate a certain angle toward the side away from or toward the locking pin 111 during the movement of the moving member 122.

[0088] Understandably, when the abutting part 123a engages with the mating part 121b, as the moving member 122 continues to move to the second position, the abutting part 123a can apply a pulling force to the locking rod 121 through the mating part 121b, thereby pulling the locking rod 121 to rotate a certain angle toward the side away from the locking pin 111; when the abutting part 123a engages with the mating part 121b, as the moving member 122 moves from the second position to the first position, the abutting part 123a can apply a pushing force to the locking rod 121 through the mating part 121b, thereby pushing the locking rod 121 to rotate the same angle toward the side closer to the locking pin 111.

[0089] like Figure 3 and Figure 4 As shown, the lock body assembly 12 also includes a lock housing 124 for connection to the second movable cover of the fairing, and has a channel portion 124a open at at least one end, with a movable member 122 movably disposed within the channel portion 124a. One end of a locking lever 121 extends into the channel portion 124a and is hinged to the end of the movable member 122, while the other end extends from the open end of the channel portion 124a to the side where the locking pin 111 is located. An elastic abutment 123 is disposed within the channel portion 124a, and includes an elastic member 123b and an abutment member 123c. The elastic member 123b is used to give the abutment member 123c a tendency to rotate toward the side closer to the locking lever 121. One end of the abutment member 123c is rotatably mounted on the lock housing 124, and the other end forms the abutment portion 123a.

[0090] Understandably, the abutment portion 123a is always in contact with the surface of the locking rod 121 under the action of the elastic member 123b. This ensures that the abutment portion 123a and the mating portion 121b are always engaged during the rotation of the locking rod 121, thereby enabling the driving engagement of the abutment portion 123a and the mating portion 121b. Furthermore, the locking rod 121 can rotate away from the locking rod 121 by overcoming the rebound force of the elastic member 123b. In addition, the channel portion 124a serves as a guide when the moving member 122 moves, ensuring that the moving member 122 can move accurately between the first position and the second position.

[0091] In this embodiment, the abutment 123c is mounted on the lock housing 124 via a fixed shaft 125. The fixed shaft 125 is fixed to the lock housing 124, one end of the abutment 123c is rotatably sleeved on the fixed shaft 125, and the elastic element 123b is a torsion spring sleeved on the fixed shaft 125. One end of the torsion spring abuts against the surface of the abutment 123c facing away from the locking rod 121, and the other end abuts against the lock housing 124. Understandably, the abutment 123c abuts against the surface of the locking rod 121 facing away from the locking pin 111 under the action of the elastic element 123b.

[0092] In this embodiment, the channel portion 124a extends along the moving direction of the moving member 122, and the open end of the channel portion 124a forms a limiting portion 124b, which is used to limit the angle of rotation of the locking rod 121 toward the side away from the locking pin 111. When the surface of the locking rod 121 abuts against the limiting portion 124b, the moving member 122 just moves to the second position.

[0093] It should be noted that when the mating part 121b reaches the abutting part 123a, most of the locking rod 121 moves to the outside of the channel part 124a, so that the locking rod 121 can rotate without being interfered with by the lock case 124.

[0094] like Figure 4 As shown, the movable member 122 is provided with four rollers 126. The movable member 122 abuts against the inner wall of the channel portion 124a through the four rollers 126. The four rollers 126 are arranged in pairs at both ends of the movable member 122, and the two rollers 126 in the same pair are parallel to each other. It can be understood that when the movable member 122 moves within the channel portion 124a, it can achieve rolling friction with the inner wall of the channel portion 124a, thereby reducing the frictional force on the movable member 122 and making it more convenient for the movable member 122 to move. In this embodiment, the rollers 126 are rolling bearings.

[0095] In this embodiment, one set of rollers 126 is sleeved on both ends of the hinge shaft connecting one end of the moving member 122 and the locking hook member, and another set of rollers 126 is sleeved on both ends of the hinge shaft connecting the other end of the moving member 122 and the connecting rod member 132.

[0096] Figure 5 This is a three-dimensional structural diagram of the lock seat assembly in an embodiment of the present invention.

[0097] like Figure 5As shown, the lock seat assembly 11 also includes a lock seat 112 for connection with the first movable cover of the fairing. A locking pin 111 is fixedly disposed on the lock seat 112 at one end facing the locking rod 121, forming a locking groove 113 with the lock seat 112. In the first position, the end of the locking hook portion 121a passes through the locking groove 113 and engages with the locking pin 111. The side wall of the locking groove 113 opposite to the locking pin 111 has a guide portion 113a, which is used to engage with the locking hook portion 121a during the movement of the moving member 122 from the first position to the second position to guide the locking hook portion 121a to slide out of the locking groove 113.

[0098] Understandably, as the moving member 122 moves from the first position to the second position, the moving member 122 can drive the locking rod member 121 to move toward the side closer to the lock seat 112, so that the locking hook part 121a can collide and engage with the guide part 113a, thereby guiding the locking hook part 121a to slide out of the locking groove 113, thereby realizing the disengagement of the locking hook part 121a from the locking pin 111.

[0099] In this embodiment, the locking groove 113 is a vertically penetrating rectangular groove so that the locking hook 121a can pass through the locking groove 113, and the guide 113a is an inclined surface that slopes toward the end of the locking hook 121a so that when the locking hook 121a and the guide 113a collide and engage, the locking hook 121a can be guided to slide out of the locking groove 113.

[0100] It should be noted that when the mating part 121b reaches the abutting part 123a, the locking hook part 121a has already slid completely out of the locking groove 113.

[0101] Figure 6 This is a three-dimensional structural diagram of the driving component in an embodiment of the present invention.

[0102] like Figure 6 As shown, the lock 10 also includes a drive assembly 13 for driving the movable member 122 to move between a first position and a second position. This drive assembly includes a first swing arm 131 and a connecting rod 132. The first swing arm 131 is rotatably mounted on the lock housing 124 and has two swing ends. One end of the connecting rod 132 is hinged to an end of the movable member 122 that is relatively away from the locking rod 121, and the other end is hinged to one swing end of the first swing arm 131. The other swing end of the first swing arm 131 is used to connect to a drive source. When the first swing arm 131 rotates, it drives the movable member 122 to move between the first position and the second position via the connecting rod 132.

[0103] Understandably, when the first swing arm 131 rotates, its swing end can drive the connecting rod 132 to rotate around the swing end, thereby driving the moving part 122 to rotate between the first position and the second position, so as to realize the locking and opening of the fairing.

[0104] Figure 7 This is a schematic diagram of the main structure of the linkage mechanism in an embodiment of the present invention.

[0105] like Figure 7 As shown, the linkage mechanism 20 includes multiple linkage rods 21. Two adjacent locks 10 transmit power through a linkage rod 21. One end of the linkage rod 21 is indirectly or directly connected to a moving part 122 within one of the locks 10, and the other end is indirectly or directly connected to a moving part 122 within the other lock 10. In this embodiment, one end of the linkage rod 21 is indirectly or directly hinged to a swing end on a first swing arm 131 within one of the locks 10 for connection to a drive source, and the other end is indirectly or directly hinged to a swing end on a first swing arm 131 within the other lock 10 for connection to a drive source.

[0106] Understandably, when one of the linkage rods 21 moves, it can drive the first swing arm 131 in the two adjacent locks 10 to rotate. When the first swing arm 131 rotates, it can drive the other linkage rods 21 to move synchronously, thereby driving the first swing arm 131 in multiple locks 10 to rotate synchronously, thus enabling the linkage unlocking or locking of multiple locks 10.

[0107] Figure 8 This is a three-dimensional structural diagram of the operating mechanism in one direction in an embodiment of the present invention; Figure 9 This is a three-dimensional structural diagram of the operating mechanism in another direction in an embodiment of the present invention.

[0108] like Figure 8 and Figure 9 As shown, the operating mechanism 30 includes a handle disc 31, a handle shaft 32, an operating handle 33, a second swing arm 34, and a reset member 35. The handle disc 31 is used to connect to the second movable cover of the fairing. The handle shaft 32 rotatably passes through the handle disc 31. The operating handle 33 is fixedly mounted on the first end of the handle shaft 32. The second swing arm 34 is fixedly mounted on the second end of the handle shaft 32 and has two swing ends, one of which is drivenly connected to one of the linkage rods 21. The reset member 35 is mounted on the handle disc 31 and connected to the other swing end of the second swing arm 34, for giving the second swing arm 34 a tendency to rotate in the locking direction. Figure 9 The direction indicated by D1 is the locking direction, and the opposite direction is the unlocking direction.

[0109] Understandably, when the operating handle 33 is rotated in the unlocking direction under force, it can drive the second swing arm 34 to rotate synchronously through the handle shaft 32, thereby driving one of the linkage rods 21 to move, and then driving the other linkage rods 21 to move synchronously. This can drive the moving parts 122 in multiple locks 10 to move from the first position to the second position, thereby realizing the linkage unlocking of multiple locks 10. When the external force on the operating handle 33 is removed, the second swing arm 34 can rotate and reset in the locking direction under the action of the reset member 35, thereby driving multiple linkage rods 21 to move back to their original positions. This can drive the moving parts 122 in multiple locks 10 to move from the second position to the first position, thereby realizing the linkage locking of multiple locks 10.

[0110] In this embodiment, the first end of the handle shaft 32 extends to one side of the outer surface of the fairing.

[0111] like Figure 9 As shown, the reset component 35 includes a reset sleeve 351, a reset rod 352, and a reset spring 353. The first end of the reset sleeve 351 is hinged to the swing end of the second swing arm 34. One end of the reset rod 352 is hinged to the lock housing 124, and the other end extends movably into the second end of the reset sleeve 351. The reset spring 353 is sleeved on the reset rod 352 at the portion outside the reset sleeve 351, with one end abutting against the second end of the reset sleeve 351 and the other end abutting against the stepped surface of the reset rod 352. Understandably, when the second swing arm 34 rotates in the unlocking direction, its swing end causes the reset sleeve 351 to slide along the reset rod 352, thereby compressing and storing force in the reset spring 353.

[0112] Figure 10 This is a schematic diagram of the connection structure between the operating mechanism and the linkage mechanism in an embodiment of the present invention.

[0113] like Figure 10 As shown, a linkage 21 connected to the swing end of the second swing arm 34 includes a first rod portion 211 and a second rod portion 212. One end of the first rod portion 211 and the second rod portion 212 are hinged to the same swing end of the second swing arm 34, and the other end of the first rod portion 211 and the second rod portion 212 are hinged to the swing end of the first swing arm 131 in the corresponding lock 10.

[0114] Figure 11 This is a three-dimensional structural diagram of the handle plate in an embodiment of the present invention.

[0115] like Figure 11As shown, the outer surface of the handle plate 31 has a recessed handle groove 311. The first end of the handle shaft 32 extends into the handle groove 311 and is connected to the end of the operating handle 33 via a connecting shaft 37. The operating handle 33 can rotate around the connecting shaft 37 between a third position and a fourth position. The operating mechanism 30 also includes a handle locking assembly 36, which is used to lock the operating handle 33 in the handle groove 311 when it is in the third position. A first torsion spring 38 is sleeved on the connecting shaft 37, which is used to give the operating handle 33 a tendency to rotate to the fourth position. When in the third position, the operating handle 33 is locked in the handle groove 311 by the handle locking assembly 36. When in the fourth position, the operating handle 33 is raised at a certain angle relative to the outer surface of the handle plate 31.

[0116] Understandably, when the fairing does not need to be opened, the operator can apply force to the operating handle 33 to rotate it to the third position and lock the operating handle 33 in the handle groove 311 through the handle locking assembly 36, thus making the operating handle 33 hidden in the handle groove 311. This achieves the hidden design of the operating handle 33, which can effectively prevent the lock 10 from being mis-locked due to accidental triggering of the operating handle 33 in non-operational situations, thereby ensuring the safety of fairing locking and protecting the operating handle 33 from damage under external forces. When the fairing needs to be opened, the operator can release the locking assembly 36 from the operating handle 33. Under the action of the first torsion spring 38, the operating handle 33 automatically rotates to the fourth position. In this position, the operating handle 33 is raised at a certain angle relative to the outer surface of the handle plate 31, thereby allowing the operator to apply force to rotate the operating handle 33.

[0117] In this embodiment, one end of the first torsion spring 38 abuts against the end face of the handle shaft 32, and the other end abuts against the inner surface of the operating handle 33.

[0118] In this embodiment, the inner shape of the handle groove 311 matches the outer shape of the operating handle 33, so that when the operating handle 33 is locked in the handle groove 311, the operating handle 33 cannot be rotated.

[0119] Figure 12 This is a three-dimensional structural diagram of the handle locking component in an embodiment of the present invention; Figure 13 This is a three-dimensional structural diagram of the locking component in an embodiment of the present invention.

[0120] like Figure 12 and Figure 13As shown, the handle locking assembly 36 includes a lock hole 361, a locking member 362, and a second torsion spring 363. The lock hole 361 is located on the side of the operating handle 33. The locking member 362 is rotatably mounted on the handle disc 31 and has a pressing part 362a and a locking key 362b for insertion and removal from the lock hole 361. When the pressing part 362a is pressed, the locking member 362 rotates in a first direction. The second torsion spring 363 is used to give the locking member 362 a tendency to rotate in the opposite direction of the first direction. When the operating handle 33 is in the third position and the pressing part 362a is pressed, the locking member 362 rotates in the first direction, thereby causing the locking key 362b to be pulled out of the lock hole 361. Then, the operating handle 33 rotates to the fourth position under the action of the second torsion spring 363. When the pressing part 362a is no longer pressed, the locking member 362 rotates in the opposite direction of the first direction to reset. Figure 12 The direction indicated by D2 is the first direction.

[0121] Understandably, when it is necessary to lock the operating handle 33 in the handle groove 311, the operator can apply force to the operating handle 33 to rotate it to the third position. In this position, the locking key 362b can be inserted into the lock hole 361, thereby blocking the rotation path of the operating handle 33 and thus locking the operating handle 33. When it is necessary to unlock the operating handle 33, the operator can press the pressing part 362a to rotate the locking member 362 in the first direction. During the rotation of the locking member 362, the locking key 362b can be pulled out from the lock hole 361, thereby removing the obstruction on the rotation path of the operating handle 33 and thus unlocking the operating handle 33. After unlocking, the operating handle 33 rotates to the fourth position under the action of the second torsion spring 363.

[0122] In this embodiment, the locking member 362 is mounted inside the handle plate 31 via a hinge shaft. A pressing opening 312 is formed on the outer surface of the handle plate 31 at a location corresponding to the pressing part 362a. In the free state, the pressing part 362a extends into the pressing opening 312, and the surface of the locking member 362 located circumferentially outward of the pressing part 362a abuts against the inner surface of the handle plate 31. Additionally, a second torsion spring 363 is sleeved on the hinge shaft, with one end abutting against the side of the locking member 362 facing away from the operating handle 33, and the other end abutting against the inner surface of the handle plate 31.

[0123] In this embodiment, the side of the locking key 362b away from the locking member 362 has an inclined surface. This inclined surface is used to engage with the operating handle 33. When the operating handle 33 is rotated to the third position under force, the locking member 362 can be rotated in the first direction through the engagement of the inclined surface with the operating handle 33. This allows the operating handle 33 to be rotated to the third position. After the operating handle 33 reaches the third position, the locking key 362b can be automatically inserted into the lock hole 361 to achieve locking, thereby realizing the automatic locking of the operating handle 33.

[0124] The role and effect of the embodiments

[0125] According to the lock and fairing locking device involved in this embodiment, the fairing locking device includes multiple locks, a linkage mechanism, and an operating mechanism. Each lock includes a lock seat assembly and a lock body assembly. The lock seat includes a locking pin. The lock body assembly includes a locking rod, a moving member, and an elastic abutment member. One end of the locking rod extends radially outward from the locking pin and is bent towards the side where the locking pin is located to form a locking hook portion for engaging with the locking pin. The other end is rotatably mounted on the moving member, which can move between a first position and a second position. The elastic abutment member has an abutment portion, and the side of the locking rod that abuts the abutment portion has a mating portion. When the moving member moves from the first position to the second position, the moving member drives the locking rod to move synchronously, thereby causing the locking hook portion to gradually disengage from the locking pin. After the engagement is completed, the moving part continues to move to the second position. Under the action of the elastic abutment, the abutment part is always in contact with the side of the locking rod facing away from the locking pin. This allows the engaging part to engage with the abutment part when it reaches the abutment part, thereby driving the locking rod to rotate a certain angle away from the locking pin. When the moving part moves to the second position, the locking hook part disengages from the locking pin, and the locking rod is raised at a certain angle relative to the locking pin. This releases the lock on the two movable covers of the fairing, thus enabling the fairing to open. Furthermore, since the locking rod is raised at a certain angle relative to the locking pin after unlocking, it can make way for the movable cover where the locking pin is located, thus not restricting the opening sequence of the two movable covers, making the opening of the fairing more convenient.

[0126] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
