Description

Technical Field

[0001] This application relates to the field of aviation partition door limit device technology, and in particular to a claw-type limit door stop for aviation use. Background Technology

[0002] Doorstops are widely used in our lives, primarily for effectively limiting and securing doors after they are opened. During the opening process, excessive force may cause the door panel to collide with the wall, resulting in damage. Doorstops act as a limiter, ensuring a safe distance between the door and the wall. Alternatively, when the door needs to remain open, doorstops can act as a fixation mechanism, preventing the door from rotating or closing uncontrollably.

[0003] The doorstops described in the relevant technologies mainly include two types: one is the magnetic type, which uses the principle of opposite poles of magnets to fix the door; the other is a reciprocating structure such as a ratchet structure.

[0004] Aircraft cabins often have partition doors to separate different areas. To protect the safety of passengers and provide a stable operating environment, these partition doors need to be effectively limited and secured when open. However, due to the special working environment of the aircraft cabin, magnets can interfere with the aircraft's instruments, rendering magnetic doorstops unusable. Furthermore, during flight, factors such as vibration, acceleration, and turning can cause instability and unreliability in reciprocating structures like ratchet mechanisms. If these mechanisms become loose, the partition door may close uncontrollably, potentially leading to accidents. Therefore, designing a suitable doorstop for aviation applications is a pressing issue. Summary of the Invention

[0005] In order to effectively limit and fix the cabin partition door to prevent it from closing uncontrollably, this application provides a claw-type limiting door stop for aviation.

[0006] The technical solution for an aviation claw-type limiting gate stop provided in this application is as follows: A claw-type limiting door stop for aviation use, comprising a limiting component and a door stop; The limiting component includes a limiting base and a striking pin. The limiting base is connected to the cabin partition door, and the striking pin is vertically arranged and connected to the limiting base. The door stop includes a mounting base, a button, a first compression spring, a slider, two claws, two limit blocks, and two second compression springs. The mounting base is mounted on the cabin floor, and the slider slides on the mounting base. The two ends of the first compression spring are connected to the mounting base and the slider, respectively. The two second compression springs are located on both sides of the slider, and the two limit blocks are located on both sides of the slider and are arranged opposite to each other. The two ends of the second compression springs are connected to the mounting base and the limit blocks, respectively. The movement direction of the second compression springs is perpendicular to the movement direction of the first compression springs. Each limit block has a limit pin formed on it. The slider has a limit hole for inserting each limit pin. The two claws are used to lock the impact pin. Both claws are rotatably connected to the slider. Each claw has a limit shaft formed on it. The mounting base has a limit groove for embedding the limit shaft. The button is used to move the two limiting blocks. In the initial state, the limiting shaft is inserted into the limiting hole and the first compression spring is in a compressed state. When the slider moves the limiting shaft from the end of the limiting groove close to the first compression spring to the end away from the first compression spring, the two claws change from a closed state to an open state.

[0007] By adopting the above technical solution, during use, the mounting base is first fixed to the bottom plate of the cabin, and the limiting base is fixed to the cabin partition door. Pressing the button causes the two limiting blocks to move away from each other. As the limiting blocks move, the limiting pin completely disengages from the limiting hole. At this time, the first compression spring pushes the slider out, causing the limiting shaft to slide along the opening direction of the limiting groove. This changes the two claws from a closed state to a fully open state. When it is necessary to fix the partition door, the impact pin strikes the slider, causing the slider to slide and compress the first compression spring, simultaneously causing the two claws to gradually close. As the slider slides, when the limiting pin and the limiting hole are aligned again, under the action of the second compression spring, the limiting pin inserts into the limiting hole, thus fixing the slider. Simultaneously, the two claws are in a closed state to lock the impact pin. When it is necessary to release the lock, simply press the button; the slider slides out, pushing the impact pin out. This effectively limits and fixes the cabin partition door. The device will not affect the instruments on the aircraft, nor will it loosen due to aircraft vibration, acceleration, turning, or other factors. It has high reliability and stability, reduces the possibility of the partition door closing uncontrollably due to external forces, and protects the safety of the occupants in the cabin.

[0008] Optionally, the limiting component further includes a fixing block, a limiting post, and a limiting spring. The fixing block has a blind hole for the limiting post and the limiting spring to be inserted. The striking pin has an adjustment hole for the limiting post to be engaged. The striking pin is connected to the fixing block through the limiting post and the limiting spring. The limiting base has a cavity formed therein. The fixing block and part of the striking pin are located in the cavity. The fixing block is connected to the limiting base by a fixing screw.

[0009] By adopting the above technical solution, the limiting component is set in two separate parts, which makes it easy to replace the clasping pin and adjust its position.

[0010] Optionally, multiple adjustment holes are provided, and the multiple adjustment holes are spaced apart along the length direction of the impact pin.

[0011] By adopting the above technical solutions, the installation position can be adjusted according to the actual situation, thereby improving the installation precision and accuracy.

[0012] Optionally, wedges are formed on the button and each of the limiting blocks. The wedges on the button are located at both ends and at the bottom of the button, and the wedges on the button are in contact with the wedges on the limiting blocks.

[0013] By adopting the above technical solution, pressing the button can ensure the stable sliding of the limit block through the cooperation of the wedge, and the button can be automatically reset when the second compression spring rebounds.

[0014] Optionally, the door stop may further include a top cover, on which a through hole is provided for the button to pass through.

[0015] By adopting the above technical solution, the top cover can play a protective role.

[0016] Optionally, the top cover and the mounting base are detachably connected.

[0017] By adopting the above technical solution, the assembly and maintenance of the door stop are facilitated.

[0018] Optionally, each edge of the top cover and the limiting base is formed with a rounded chamfer.

[0019] By adopting the above technical solution, the rounded chamfer can play a role in safety protection.

[0020] Optionally, each of the wedge-shaped parts of the button has a baffle extending outward on both sides, the baffle being used to abut against the lower surface of the top cover when the button pops up.

[0021] By adopting the above technical solution, the baffle can play a limiting role and prevent the button from being bounced away.

[0022] Optionally, the door stop further includes a limiting frame, and three limiting frames are provided. All three limiting frames are connected to the mounting base. The limiting frames are used to restrict the limiting block or the slider from sliding along the length direction of the limiting frame.

[0023] By adopting the above technical solution, the limiting frame can ensure the stability of the limiting block and the slider when they slide.

[0024] Optionally, the end of the slider away from the first compression spring is formed with an arc-shaped groove.

[0025] By adopting the above technical solution, the arc-shaped groove can cover the impact pin, ensuring the accuracy of the impact pin's position on the slider.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a claw-type limiting door stop, which can effectively limit the opening of the cabin partition door, preventing the partition door from closing uncontrollably due to abnormal vibration during aircraft operation, protecting the safety of the crew, effectively distinguishing the cabin area, and providing a stable operating environment for the occupants; 2. In this application, to avoid the reciprocating unlocking method of conventional doorstops, the claw-type limit stop uses a vertically arranged spring and slider to achieve self-limiting of the limit stop. The slider has a rotatable claw with a protruding pin. The pin on the claw can slide in a corresponding groove on the base, allowing the claw to open and close during the sliding process. Simultaneously, when the claw slider slides to a certain position, the protruding limit pin on the vertically arranged limit slider can extend into the limit hole of the claw slider, achieving the limit of the claw-type limit stop when locked. Releasing the claw-type limit stop requires pressing a button. The lower part of the button is designed with a wedge shape, which, during downward movement, disengages the limit slider from the limit hole of the claw slider, releasing the claw slider. Under the action of the spring, the claw slider pushes out the striking pin, releasing the claw-type limit stop. 3. In this application, the limiting component includes a striking pin, a striking pin limiting post, and a striking pin limiting spring. After the striking pin, striking pin limiting post, and striking pin limiting spring are pressed onto the striking pin fixing block in sequence, the entire component is inserted into the limiting base. The striking pin fixing screw fixes the striking pin fixing block to the limiting base. The striking pin has multiple adjustment holes. By cooperating with the adjustment holes, the striking pin limiting post, and the striking pin limiting spring, the overall installation position of the limiting component can be adjusted to meet different installation requirements.

[0029] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0030] This application discloses a claw-type limiting door stop for aviation applications, see reference... Figure 1 and Figure 2 The claw-type limiting door stop for aviation includes a limiting component 1 and a door stop 2. The limiting component 1 is installed on the cabin partition door, and the door stop 2 is installed on the cabin floor. The limiting component 1 includes a striking pin 11 and a limiting base 12. The limiting base 12 is connected to the cabin partition door, and the striking pin 11 is connected to the limiting base 12 and is vertically set. The door stop 2 includes a slider 21, a button 22, and two claws 23. Both claws 23 are rotatably connected to the slider 21. The button 22 can drive the slider 21 to slide, and the sliding of the slider 21 can cause the two claws 23 to close or open.

[0031] Before use, install the limiting component 1 and the door stop 2 in their respective positions. Press button 22, which will push the slider 21 out, and simultaneously, the two claws 23 will change from a closed state to a fully open state. Open the cabin partition door to the corresponding position, and the impact pin 11 will strike the slider 21, causing the slider 21 to reset and be fixed. At the same time, the two claws 23 will change from an open state to a closed state, thus limiting and fixing the impact pin 11. When the cabin partition door needs to be closed, press button 22 to push the slider 21 out. This effectively limits and fixes the cabin partition door. This device will not affect the instruments on the aircraft, nor will it loosen due to aircraft vibration, acceleration, or turning. It has high reliability and stability.

[0032] Specifically, refer to Figure 3 and Figure 4 The door stop 2 also includes a mounting base 24, a first compression spring 25, two limit blocks 26, and two second compression springs 27. The mounting base 24 is mounted on the floor of the cabin. The slider 21 is slidably connected to the mounting base 24. The two ends of the first compression spring 25 are respectively connected to the mounting base 24 and the slider 21. The two second compression springs 27 are respectively located on both sides of the slider 21. The two limit blocks 26 are respectively located on both sides of the slider 21. The moving direction of the limit blocks 26 is perpendicular to the moving direction of the slider 21. The two ends of the second compression springs 27 are respectively connected to the mounting base 24 and the limit blocks 26. Each limit block 26 has a limit pin 28 formed on it. The slider 21 has a limit hole 29 for each limit pin 28 to be inserted. Each claw 23 has a limit shaft 210 formed at its bottom. The mounting base 24 has a limit groove 211 for the limit shaft 210 to be embedded in it. The limit groove 211 and the limit shaft 210 are set one-to-one. The button 22 is used to drive the two limit blocks 26 to move.

[0033] Pressing button 22 causes the two limiting blocks 26 to move away from each other. Simultaneously, each limiting block 26 compresses its corresponding second compression spring 27. As the limiting blocks 26 slide, the limiting pin 28 disengages from the limiting hole 29, thus losing its limiting effect on the slider 21. The first compression spring 25, now compressed, pushes the slider 21 out. Simultaneously, utilizing the cooperation of the limiting shaft 210 and the limiting groove 211, the limiting shaft 210 slides within the limiting groove 211, causing the two claws 23 to change from a closed state to an open state. When the striking pin 11 strikes the slider 21, the slider 21 slides, compressing the first compression spring 25. As the slider 21 slides, when the limiting pin 28 aligns with the limiting hole 29, under the action of the second compression spring 27, the limiting pin 28 inserts into the limiting hole 29, achieving the limiting and fixing of the slider 21. Simultaneously, under the guidance of the limiting groove 211, the two claws 23 close, thereby limiting and fixing the collision pin 11, thus achieving the fixation of the cabin partition door.

[0034] Understandably, when button 22 is not applied, the limiting shaft 210 is inserted into the limiting hole 29, and the first compression spring 25 is in a compressed state. According to the operational requirements, the limiting groove 211 should satisfy the following: when the limiting shaft 210 moves from the end of the limiting groove 211 near the first compression spring 25 to the end away from the first compression spring 25, the two claws 23 change from a closed state to a fully open state; that is, the distance between the ends of the two limiting grooves 211 near the first compression spring 25 is less than the distance between the ends of the two limiting grooves 211 away from the first compression spring 25.

[0035] Reference Figure 3 and Figure 4 Two claws 23 are rotatably connected to the end of the slider 21 away from the first compression spring 25 via pins, and the two claws 23 are symmetrically arranged about the center line of the slider 21. In this way, when the striking pin 11 strikes the slider 21, the two claws 23 can accurately cover the striking pin 11, achieving stable and accurate fixation of the striking pin 11. Of course, the two second compression springs 27 should also be symmetrically arranged about the center line of the slider 21, and the overall structure should be symmetrical about the center line of the mounting base 24 to further improve stability.

[0036] In this embodiment, refer to Figure 4 and Figure 5 The striking pin 11 is cylindrical, so an arc-shaped groove 3 is formed at the end of the slider 21 away from the first compression spring 25. When the striking pin 11 strikes the slider 21, the impact position is located within the arc-shaped groove 3, which ensures the accuracy of the striking position of the striking pin 11 and thus achieves stable sliding of the slider 21. At the same time, each claw 23 is arc-shaped, which fits the shape of the striking pin 11. When the two claws 23 limit the striking pin 11, the circumference of the striking pin 11 can fit tightly with the claws 23. In this way, when the striking pin 11 is subjected to external force or vibration, the striking pin 11 has no room to move, ensuring the overall stability.

[0037] Reference Figure 3 The door stop 2 also includes three limiting frames 212, all of which are connected and fixed to the mounting base 24. The limiting frames 212 are U-shaped. This allows the limiting frames 212 to restrict the sliding of the limiting block 26 or the slider 21 along its length, improving the stability of the sliding process and preventing deviation. Of course, the limiting frames 212 can also be used to fix the first compression spring 25 or the second compression spring 27, improving installation convenience.

[0038] Of course, refer to Figure 3 and Figure 5The door stop 2 also includes a top cover 213, which has a through hole for the button 22 to pass through. The top cover 213 can cover various components to provide protection. To facilitate the installation, maintenance, or replacement of various components, the top cover 213 and the mounting base 24 are detachably connected. In this embodiment, the top cover 213 and the mounting base 24 are connected by short screws, the mounting base 24 is connected to the cabin floor by long screws, and the limiting base 12 is connected to the cabin partition door by short screws. Of course, other connection methods that meet the requirements can also be used.

[0039] Considering the special operating environment of this device, and to ensure the safety of the occupants, each edge of the top cover 213 and the limiting base 12 is formed with a rounded chamfer 4. The rounded chamfer 4 can reduce the sharpness of the edges and play a safety protection role. In addition, the top cover 213 and the limiting base 12 can be made of some flexible materials while meeting the strength requirements, or some protective pads or rubber pads can be added to the surface of the top cover 213 and the limiting base 12, etc., as safety protection measures.

[0040] Reference Figure 6 and Figure 7 Both the button 22 and each limiting block 26 have wedge-shaped bodies 5 formed on them. The button 22 has two wedge-shaped bodies 5, located at both ends and the bottom of the button 22. The wedge-shaped bodies 5 on the button 22 can fit into contact with the wedge-shaped bodies 5 on the limiting blocks 26. When the button 22 is pressed, utilizing the special structure of the wedge-shaped bodies 5, the wedge-shaped bodies 5 on the button 22 and the wedge-shaped bodies 5 on the limiting blocks 26 slide relative to each other, causing the button 22 to move downwards. Simultaneously, the two limiting blocks 26 move in a direction that is relatively far apart. When the two limiting blocks 26 move in a direction that is relatively close together, the button 22 can be lifted, thereby achieving automatic reset of the button 22.

[0041] Reference Figure 5 and Figure 7 Each wedge-shaped body 5 of button 22 has a baffle 6 extending outward from both sides. When button 22 is reset, the baffle 6 can abut against the lower surface of top cover 213 to achieve the function of limiting the position and prevent button 22 from being ejected due to the large force when it bounces upward. At the same time, it can fix button 22.

[0042] Reference Figure 8 and Figure 9 The limiting component 1 also includes a fixing block 13, a limiting post 14, and a limiting spring 15. The fixing block 13 has a blind hole 7 for the limiting post 14 and the limiting spring 15 to be inserted. The striking pin 11 has an adjustment hole 8 for the limiting post 14 to be engaged. The limiting base 12 has a cavity 16 formed on it. The fixing block 13 and part of the striking pin 11 are located in the cavity 16. The fixing block 13 is connected to the limiting base 12 by a fixing screw 9.

[0043] During assembly, the limiting post 14 and the limiting spring 15 are inserted into the blind hole 7, with the end of the limiting post 14 away from the limiting spring 15 abutting against the adjusting hole 8. The fixing block 13, the limiting post 14, the limiting spring 15, and the striking pin 11 are then placed into the cavity 16 as a whole. Finally, the fixing block 13 is connected and fixed to the limiting base 12 using the fixing screws 9. The limiting component 1 is designed as a separate unit, facilitating the replacement of the striking pin 11. At the same time, the use of the limiting post 14 and the limiting spring 15 improves the compactness of the structure.

[0044] Multiple adjustment holes 8 are provided, and these holes 8 are spaced apart along the length of the striker 11. The installation position can be adjusted according to the actual situation, and appropriate adjustment holes 8 can be selected to improve installation accuracy and precision.

[0045] Of course, in order to ensure the stability of the connection, in this embodiment, two blind holes 7 are provided on the fixing block 13, and two limit posts 14 and two limit springs 15 are provided. The two blind holes 7 are arranged in the vertical direction, and the distance between the two blind holes 7 is equal to the distance between the adjustment holes 8.

[0046] The implementation principle of a claw-type limiting door stop for aviation applications according to this application embodiment is as follows: In use, firstly, based on the specific conditions of the cabin partition door, select the appropriate adjustment hole 8 on the impact pin 11, and install the impact pin 11 onto the limiting base 12 via the limiting post 14, limiting spring 15, fixing block 13, and fixing screw 9. Then, install the limiting base 12 onto the cabin partition door using short screws. Next, assemble the door stop 2 as required and fix it to the cabin floor using long screws. When it is necessary to fix the cabin partition door, press button 22. Under the action of button 22, the two limiting blocks 26 move away from each other. As the limiting blocks 26 move, the limiting pins 28 completely disengage from the limiting holes 29. Under the action of the second compression spring 27, the first compression spring 25 pushes out the slider 21, while the limiting shaft 210 slides along the opening direction of the limiting groove 211. Each limiting pin 28 abuts against the side wall of the slider 21, thus changing the two claws 23 from a closed state to a fully open state. When the partition door needs to be secured, it moves to the appropriate position, and the striking pin 11 strikes the slider 21. The slider 21 slides and compresses the first compression spring 25, simultaneously causing the two claws 23 to gradually close. As the slider 21 slides, when the limiting pin 28 and the limiting hole 29 align again, under the action of the second compression spring 27, the limiting pin 28 inserts into the limiting hole 29, thus securing the slider 21. At the same time, the two claws 23 are in a closed state, locking the striking pin 11. When it is necessary to release the lock, simply press the button 22, and the slider 21 slides out, pushing the striking pin 11 out. This effectively limits and secures the cabin partition door, reducing the possibility of the partition door closing uncontrollably due to external force and protecting the safety of the occupants inside the cabin.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
