Description

Technical Field

[0001] This invention belongs to the technical field of aviation locking mechanism equipment, specifically relating to an aviation opening support closing locking mechanism and method. Background Technology

[0002] The aircraft-grade open support and close locking mechanism is used to switch the side guide rail from the working state to the non-working state. The existing structure is bulky and has the risk of failure. In addition, the side guide rail has no effective buffer function when switching from the open support to the closed lock state, and the closing process is noisy. Furthermore, the existing side guide rail only relies on gravity to maintain the closed state, which causes abnormal noise in the vibrating environment. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the present invention provides an aviation opening support closing locking mechanism and method, which can effectively solve the above problems.

[0004] The technical solution adopted in this invention is as follows:

[0005] The present invention provides an aviation opening support closing locking mechanism, comprising: a side guide rail body (1), a base (2), a support lock sleeve (3), and a support lock hook assembly (4).

[0006] One end of the side guide rail body (1) is rotatably connected to a fixing member; a horizontal base (2) is provided below the side guide rail body (1); a support lock sleeve (3) perpendicular to the side guide rail body (1) is fixedly installed on the side of the side guide rail body (1) facing the base (2); a support lock hook assembly (4) is provided on the side of the base (2) facing the side guide rail body (1) and opposite to the support lock sleeve (3); when the side guide rail body (1) is rotated to the horizontal closed state, the support lock sleeve (3) and the support lock hook assembly (4) are locked together; when the side guide rail body (1) is rotated to the open support state, the bottom surface of the support lock sleeve (3) is supported on the top surface of the support lock hook assembly (4) to achieve stable support.

[0007] Furthermore, the support lock sleeve (3) has a groove (3-1) on the side facing the support lock hook assembly (4); the support lock hook assembly (4) includes a support lock hook (4-1), a lock hook pivot (4-2), a torsion spring (4-3), and a force plate (4-4).

[0008] The bottom of the support hook (4-1) is rotatably connected to the base (2) through the hook pivot (4-2), so that the support hook (4-1) can rotate and switch between a vertical state and an inclined state away from the support lock sleeve (3); the rotation direction of the support hook (4-1) from the vertical state to the inclined state is clockwise.

[0009] When the support hook (4-1) is in a vertical position, its hook part is locked in place with the groove (3-1) of the support lock sleeve (3) in a vertical position; the torsion spring (4-3) is assembled on the hook shaft (4-2) and abuts against the outside of the support hook (4-1), applying a force to the support hook (4-1) to rotate the support hook (4-1) counterclockwise;

[0010] The force-bearing plate (4-4) is fixedly installed on the side of the support hook (4-1).

[0011] Furthermore, the side guide rail body (1) has a through hole (1-1); the operating rod (5) passes through the through hole (1-1) and acts on the force plate (4-4), so that the force plate (4-4) is subjected to force, thereby causing the support lock hook (4-1) to overcome the force of the torsion spring (4-3) and rotate clockwise.

[0012] Furthermore, it also includes a buffer spring (6);

[0013] The side guide rail body (1) has a buffer spring (6) fixedly installed on the side facing the base (2) and perpendicular to the side guide rail body (1); the buffer spring (6) is located on one side of the support lock sleeve (3).

[0014] Furthermore, it also includes a pull rod assembly (7);

[0015] The pull rod assembly (7) includes a pull rod upper support (7-1), a pull rod hook (7-2), a tension spring (7-3), a pull rod base (7-4), and a pull rod pivot (7-5).

[0016] The side guide rail body (1) is located on the side facing the base (2) and on the side of the support lock sleeve (3), and the upper support of the pull rod (7-1) is fixedly installed. The top of the pull rod hook (7-2) is rotatably connected to the upper support of the pull rod (7-1). The tension spring (7-3) is vertically arranged, and its two ends are respectively connected to the upper support of the pull rod (7-1) and the pull rod hook (7-2).

[0017] The base (2) is fixedly provided with the pull rod base (7-4) on the side facing the side guide rail body (1) and opposite to the upper support (7-1) of the pull rod; the top surface of the pull rod base (7-4) is rotatably mounted with the horizontal pull rod shaft (7-5).

[0018] The tail of the pull rod hook (7-2) is an upward-curved arc. When the side guide rail body (1) is rotated to the open support state, the tail of the pull rod hook (7-2) hooks onto the lower part of the pull rod shaft (7-5). The pull rod shaft (7-5) limits the open support state of the side guide rail body (1).

[0019] Furthermore, the fixing member is the hinge fixing side (8); one end of the side guide rail body (1) is rotatably connected to the hinge fixing side (8) through the side guide rail pivot (9).

[0020] The present invention also provides a method for opening the aviation support and closing the locking mechanism as described above, comprising:

[0021] Step S1, disable the lock:

[0022] When the lock is closed, the side guide rail body (1) is horizontal and the support lock sleeve (3) is vertical. The support lock hook (4-1) of the support lock hook assembly (4) is kept vertical under the force of the torsion spring (4-3), so that the hook part of the support lock hook (4-1) is engaged in the groove (3-1) of the support lock sleeve (3), which plays a blocking function on the support lock sleeve (3) and ensures the stability and reliability of the lock is closed.

[0023] Step S2, switch from the locked state to the open support state:

[0024] When it is necessary to open the side guide rail body (1), use the operating rod (5) to pass through the through hole (1-1) of the side guide rail body (1) and make the end of the operating rod (5) abut against the surface of the force plate (4-4) fixed with the support lock hook (4-1). The operating rod (5) presses down the force plate (4-4), so that the force plate (4-4) overcomes the force of the torsion spring (4-3) and rotates clockwise, thereby driving the lock hook part of the support lock hook (4-1) to disengage from the groove (3-1) of the support lock sleeve (3) to realize the unlocking function;

[0025] When the hook part of the support lock hook (4-1) disengages from the groove (3-1) of the support lock sleeve (3), the side guide rail body (1) rotates counterclockwise upward a certain distance under the action of the side guide rail pivot (9); then the operating lever (5) is used to flip the side guide rail body (1) upward, so that the side guide rail body (1) rotates to the open support state; and the support lock hook (4-1) returns to the vertical state under the force of the torsion spring (4-3);

[0026] Step S3, activate the support mode:

[0027] When the side guide rail body (1) rotates to the open support state, the support lock hook (4-1) returns to the vertical state under the force of the torsion spring (4-3), the bottom of the support lock sleeve (3) is supported on the top surface of the support lock hook (4-1), and since the support point of the support lock sleeve (3) exceeds the rotation center of the support lock hook (4-1), that is, the support point is located inside the rotation normal of the support lock hook (4-1), and it remains locked under the gravity of the side guide rail body (1);

[0028] Meanwhile, when the side guide rail body (1) rotates to the open support state, the pull rod assembly (7) limits the angle of the open support. When the side guide rail body (1) rotates to the position, under the action of the tension spring (7-3), the bottom end of the pull rod hook (7-2) is always in contact with the pull rod shaft (7-5) to prevent the side guide rail body (1) from flipping up counterclockwise. This state can effectively bear the load and the support state is stable and reliable.

[0029] Step S4, transition from the open support state to the closed lock state:

[0030] When it is necessary to close the side guide rail body (1), use the operating rod (5) to pass through the through hole (1-1) of the side guide rail body (1) and act on the force plate (4-4) fixed with the support lock hook (4-1) to apply a clockwise rotational force to the force plate (4-4); press down the operating rod (5) to make the support lock hook (4-1) rotate clockwise and destroy the support structure; then pull out the operating rod (5), step on the side guide rail body (1) to the horizontal state, at this time, the support lock hook (4-1) returns to the vertical state under the elastic force of the torsion spring (4-3), and cooperates with the groove (3-1) of the support lock sleeve (3) to reach the closed and locked state;

[0031] During the closing process, the side guide rail body (1) will fall under the action of gravity. After falling a certain distance, the buffer spring (6) will contact the surface of the base (2) to play a buffering role, so that the closing process can be achieved safely and smoothly.

[0032] The aviation opening support closing locking mechanism and method provided by the present invention have the following advantages:

[0033] The present invention features a small structural volume, light overall weight, convenient operation, and easy installation. It enables rapid opening and closing of the side guide rails, and incorporates a buffer function during the closing process to enhance safety. The present invention boasts comprehensive functionality, reliable structure, high ergonomics, and a low failure rate. Attached Figure Description

[0044] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the invention.

[0045] This invention provides an aviation opening support closing locking mechanism, which is an aviation locking mechanism device. It is mainly a locking mechanism that serves two purposes and prevents the pull rod assembly from flipping over. It is used in mechanisms such as side guide rails and auxiliary guide rails that require flipping to open for support and closing for locking.

[0046] The present invention features a small structural volume, light overall weight, convenient operation, and easy installation. It enables rapid opening and closing of the side guide rails, and incorporates a buffer function during the closing process to enhance safety. The present invention boasts comprehensive functionality, reliable structure, high ergonomics, and a low failure rate.

[0047] See Figures 1 to 8 The present invention provides an aviation opening support closing locking mechanism, comprising: a side guide rail body 1, a base 2, a support lock sleeve 3, and a support lock hook assembly 4;

[0048] One end of the side guide rail body 1 is rotatably connected to a fixing member; for example, the fixing member is a hinge fixing side 8; one end of the side guide rail body 1 is rotatably connected to the hinge fixing side 8 through the side guide rail pivot 9.

[0049] A horizontal base 2 is provided below the side guide rail body 1; the base 2 is fixed to the floor; a support lock sleeve 3 perpendicular to the side guide rail body 1 is fixedly installed on the side of the side guide rail body 1 facing the base 2; a support lock hook assembly 4 is provided on the side of the base 2 facing the side guide rail body 1 and opposite to the support lock sleeve 3; when the side guide rail body 1 is rotated to the horizontal closed state, the support lock sleeve 3 and the support lock hook assembly 4 are locked together; when the side guide rail body 1 is rotated to the open support state, the bottom surface of the support lock sleeve 3 is supported on the top surface of the support lock hook assembly 4 to achieve stable support.

[0050] In this invention, the support lock sleeve 3 has a groove 3-1 on the side facing the support lock hook assembly 4; the support lock hook assembly 4 includes a support lock hook 4-1, a lock hook rotating shaft 4-2, a torsion spring 4-3, and a force-bearing plate 4-4; the bottom of the support lock hook 4-1 is rotatably connected to the base 2 through the lock hook rotating shaft 4-2, allowing the support lock hook 4-1 to rotate and switch between a vertical state and an inclined state away from the support lock sleeve 3; the rotation direction of the support lock hook 4-1 from the vertical state to the inclined state is clockwise; when the support lock hook 4-1 is in the vertical state, its lock hook part is locked and engaged with the groove 3-1 of the vertical support lock sleeve 3; the torsion spring 4-3 is assembled on the lock hook rotating shaft 4-2 and abuts against the outside of the support lock hook 4-1, applying a force to the support lock hook 4-1 to rotate counterclockwise; the force-bearing plate 4-4 is fixedly installed on the side of the support lock hook 4-1.

[0051] A buffer spring 6 perpendicular to the side guide rail body 1 is fixedly installed on the side facing the base 2; the buffer spring 6 is located on one side of the support lock sleeve 3.

[0052] In this invention, to achieve the opening support limit and improve the stability when the support is opened, a pull rod assembly 7 can be further provided; the pull rod assembly 7 includes a pull rod upper support 7-1, a pull rod hook 7-2, a tension spring 7-3, a pull rod base 7-4, and a pull rod pivot 7-5;

[0053] The side guide rail body 1 faces the base 2 and is located on the side of the support lock sleeve 3. The upper support 7-1 of the pull rod is fixedly installed. The top of the pull rod hook 7-2 is rotatably connected to the upper support 7-1 of the pull rod. The tension spring 7-3 is set vertically, and its two ends are connected to the upper support 7-1 of the pull rod and the pull rod hook 7-2 respectively.

[0054] A pull rod base 7-4 is fixedly installed on the side of the base 2 facing the side guide rail body 1 and opposite to the upper support 7-1 of the pull rod; a horizontal pull rod shaft 7-5 is rotatably installed on the top surface of the pull rod base 7-4;

[0055] The tail of the pull rod hook 7-2 is an upward-curved arc. When the side guide rail body 1 rotates to the open support state, the tail of the pull rod hook 7-2 hooks onto the lower part of the pull rod shaft 7-5, and the pull rod shaft 7-5 limits the open support state of the side guide rail body 1.

[0056] In this invention, for ease of operation, the side guide rail body 1 has a through hole 1-1; the operating rod 5 passes through the through hole 1-1 and acts on the force plate 4-4, so that the force plate 4-4 is subjected to force, thereby causing the support lock hook 4-1 to rotate clockwise against the force of the torsion spring 4-3.

[0057] The present invention also provides an operation method for an aviation-grade open support and close locking mechanism, comprising:

[0058] Step S1, disable the lock:

[0059] like Figure 3 As shown, when the lock is closed, the side guide rail body 1 is horizontal and the support lock sleeve 3 is vertical. The support lock hook 4-1 of the support lock hook assembly 4 is kept vertical under the force of the torsion spring 4-3, so that the hook part of the support lock hook 4-1 is engaged in the groove 3-1 of the support lock sleeve 3, which plays a blocking function on the support lock sleeve 3 and ensures the stability and reliability of the lock is closed.

[0060] In this invention, when the locking state is closed, the support hook 4-1 remains locked under the force of the torsion spring 4-3, and the locking is stable and reliable.

[0061] Step S2, switch from the locked state to the open support state:

[0062] When it is necessary to open the side guide rail body 1, use the operating rod 5 to pass through the through hole 1-1 of the side guide rail body 1, and make the end of the operating rod 5 abut against the surface of the force plate 4-4 fixed to the support lock hook 4-1. The operating rod 5 presses down on the force plate 4-4, causing the force plate 4-4 to rotate clockwise against the force of the torsion spring 4-3, thereby driving the lock hook part of the support lock hook 4-1 to disengage from the groove 3-1 of the support lock sleeve 3, realizing the unlocking function. This process is easy and convenient to operate and meets the needs of multiple operations.

[0063] When the hook part of the support lock hook 4-1 disengages from the groove 3-1 of the support lock sleeve 3, the side guide rail body 1 rotates counterclockwise upward a certain distance under the action of the side guide rail pivot 9; then the operating lever 5 is used to flip the side guide rail body 1 upward, so that the side guide rail body 1 rotates to the open support state; and the support lock hook 4-1 returns to the vertical state under the force of the torsion spring 4-3.

[0064] Step S3, activate the support mode:

[0065] The support lock's opening and support functions primarily rely on the support lock sleeve 3 being supported on the upper surface of the support lock hook 4-1. For example... Figure 4 As shown, when the side guide rail body 1 rotates to the open support state, the support lock hook 4-1 returns to the vertical state under the force of the torsion spring 4-3. The bottom of the support lock sleeve 3 is supported on the top surface of the support lock hook 4-1. Furthermore, since the support point of the support lock sleeve 3 exceeds the rotation center of the support lock hook 4-1, that is, the support point is located inside the rotation normal of the support lock hook 4-1, it remains locked under the gravity of the side guide rail body 1.

[0066] Meanwhile, when the side guide rail body 1 rotates to the open support state, the pull rod assembly 7 limits the angle of the open support. Furthermore, when the side guide rail body 1 rotates to the correct position, under the action of the tension spring 7-3, the bottom end of the pull rod hook 7-2 is always in contact with the pull rod shaft 7-5, preventing the side guide rail body 1 from flipping up counterclockwise. This state can effectively bear load, and the support state is stable and reliable, adapting to vibration and impact conditions.

[0067] Step S4, transition from the open support state to the closed lock state:

[0068] When it is necessary to close the side guide rail body 1, use the operating rod 5 to pass through the through hole 1-1 of the side guide rail body 1 and act on the force plate 4-4 fixed with the support lock hook 4-1, and apply a clockwise rotational force to the force plate 4-4; press down the operating rod 5 to make the support lock hook 4-1 rotate clockwise, destroying the support structure; then pull out the operating rod 5, step on the side guide rail body 1 to the horizontal state, at this time, the support lock hook 4-1 returns to the vertical state under the elastic force of the torsion spring 4-3, and cooperates with the groove 3-1 of the support lock sleeve 3 to reach the closed and locked state;

[0069] During the closing process, the side guide rail body 1 will fall under the action of gravity. After falling a certain distance, the buffer spring 6 will contact the surface of the base 2, which will have a buffering effect, so that the closing process can be achieved safely and smoothly.

[0070] In practical applications, the assembly process of the support lock is as follows: Figure 1As shown, the torsion spring 4-3, the support lock hook 4-1 and the base 2 are connected to the mounting hole by the lock hook shaft 4-2. The pull rod hook 7-2 is connected to the upper support 7-1 of the pull rod, and then connected to the side guide rail body 1. The tension spring 7-3 is connected to the side guide rail body 1 and the pull rod hook 7-2 respectively. The side guide rail shaft 9 passes through the mounting hole of the side guide rail body 1 and the hinge fixing side 8 to complete the assembly.

[0071] How to use the support lock:

[0072] Close the lock as follows Figure 6 As shown, insert the operating lever 5 into the corresponding through hole 1-1 of the side guide rail body 1, press down on the inclined surface of the force plate 4-4 to destroy the support structure, and the side guide rail body 1 falls by its own weight. The buffer spring 6 buffers the fall. Then, remove the operating lever 5 and press down on the side guide rail body 1 with your foot until it is horizontal, thus completing the closing and locking.

[0073] Open the support as Figure 5 As shown, insert the operating lever 5 into the corresponding through hole 1-1 of the side guide rail body 1, press down on the inclined surface of the force plate 4-4 to break the locking structure, and the side guide rail body 1 will spring up under the action of the buffer spring 6. Then, use the operating lever 5 to rotate the side guide rail body 1 counterclockwise into place, support the locking hook 4-1 in a vertical state, and pull out the operating lever 5 to complete the opening of the support.

[0074] Figure 7 This is a schematic diagram of the support lock in the locked state after installation. The support lock sleeve 3, buffer spring 6, and upper support of the pull rod 7-1 are installed on the side guide rail body 1 with screws. The support lock hook 4-1 and its mating parts are assembled and then installed on the floor with screws. Figure 8 The diagram shows the opening and closing of the support rail after the lock is installed. When it is necessary to close or open, the operating lever 5 is inserted into the main body 1 of the side rail and pressed down to break the stability and unlock, thus realizing the state transition.

[0075] The present invention provides an opening support and closing locking mechanism, in which the support lock mechanism can effectively limit and lock the side guide rail. This invention utilizes a dead-point position to lock and support the side guide rail, ensuring stable locking and support. By employing the lever principle, opening and closing the side guide rail is both safe and convenient. The support lock is small in size, reliable in structure, has a strong load-bearing capacity, is safe and stable, compact in structure, and lightweight, making it suitable for use in aerospace products.

[0076] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

The operating rod (5) presses down the force plate (4-4), so that the force plate (4-4) overcomes the force of the torsion spring (4-3) and rotates clockwise, thereby driving the lock hook part of the support lock hook (4-1) to disengage from the groove (3-1) of the support lock sleeve (3) to realize the unlocking function; When the hook part of the support lock hook (4-1) disengages from the groove (3-1) of the support lock sleeve (3), the side guide rail body (1) rotates counterclockwise upward a certain distance under the action of the side guide rail pivot (9); then the operating lever (5) is used to flip the side guide rail body (1) upward, so that the side guide rail body (1) rotates to the open support state; and the support lock hook (4-1) returns to the vertical state under the force of the torsion spring (4-3); Step S3, activate the support mode: When the side guide rail body (1) rotates to the open support state, the support lock hook (4-1) returns to the vertical state under the force of the torsion spring (4-3), the bottom of the support lock sleeve (3) is supported on the top surface of the support lock hook (4-1), and since the support point of the support lock sleeve (3) exceeds the rotation center of the support lock hook (4-1), that is, the support point is located inside the rotation normal of the support lock hook (4-1), and it remains locked under the gravity of the side guide rail body (1); Meanwhile, when the side guide rail body (1) rotates to the open support state, the pull rod assembly (7) limits the angle of the open support. When the side guide rail body (1) rotates to the position, under the action of the tension spring (7-3), the bottom end of the pull rod hook (7-2) is always in contact with the pull rod shaft (7-5) to prevent the side guide rail body (1) from flipping up counterclockwise. This state can effectively bear the load and the support state is stable and reliable. Step S4, transition from the open support state to the closed lock state: When it is necessary to close the side guide rail body (1), use the operating rod (5) to pass through the through hole (1-1) of the side guide rail body (1) and act on the force plate (4-4) fixed with the support lock hook (4-1) to apply a clockwise rotational force to the force plate (4-4); press down the operating rod (5) to make the support lock hook (4-1) rotate clockwise and destroy the support structure; then pull out the operating rod (5), step on the side guide rail body (1) to the horizontal state, at this time, the support lock hook (4-1) returns to the vertical state under the elastic force of the torsion spring (4-3), and cooperates with the groove (3-1) of the support lock sleeve (3) to reach the closed and locked state; During the closing process, the side guide rail body (1) will fall under the action of gravity. After falling a certain distance, the buffer spring (6) will contact the surface of the base (2) to play a buffering role, so that the closing process can be achieved safely and smoothly.
