Description

Technical Field

[0001] This utility model relates to the field of aviation component technology, and in particular to an adjustment handle. Background Technology

[0002] In the aviation industry, providing a comfortable and fully functional seating environment for passengers and crew is of paramount importance. The various adjustment functions of a seat, such as fore-and-aft adjustment, backrest angle adjustment, and headrest height and angle changes, directly affect the user's riding experience and ease of operation. Currently, most aircraft seat adjustments rely on specific adjustment devices, with the adjustment handle, as a key control component, playing a crucial role in accurately transmitting the user's commands to the seat adjustment mechanism, thereby enabling the adjustment of various seat parameters.

[0003] As disclosed in prior art patent application number CN201821789202.9, an aircraft seat adjustment handle includes a vertical fixed rod, a horizontal fixed rod, an adjustment rod, and a movable rod. The top of the horizontal fixed rod is welded to a vertical fixed rod, and a fixing hole is formed on one side of the surface of the horizontal fixed rod. A first rotating shaft is fixedly installed on one side of the front surface of the horizontal fixed rod, and an adjustment rod is rotatably installed on the surface of the first rotating shaft. A third rotating shaft is welded to the bottom of the inner part of the adjustment rod, and a spring is welded to the top of the third rotating shaft. A movable rod is welded to the top of the spring, and a thread is formed on the surface of the movable rod. The thread engages with the thread on the inner surface of a mounting block, and the mounting block is welded to one end of the inner wall of the adjustment rod. A second rotating shaft is connected to one end of the movable rod, and a central shaft is installed in the middle of the second rotating shaft. This utility model modifies the traditional adjustment rod by installing a movable rod that can engage and rotate, facilitating side restraint of passengers on the aircraft seat and ensuring their safety.

[0004] However, in the above method, the vertical fixing rod and the horizontal fixing rod are connected by welding, which means that if any part is damaged, the whole thing must be discarded and replaced, making it less practical. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustment handle that solves the technical problem in the prior art where the vertical fixing rod and the horizontal fixing rod are connected by welding, which means that if any part is damaged, the entire handle must be discarded and replaced, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides an adjustment handle, including a vertical fixing rod, a horizontal fixing rod, a handle assembly, and an assembly mechanism. The handle assembly is connected to the horizontal fixing rod and has a sweat-absorbing band. The horizontal fixing rod has mounting holes. The assembly mechanism includes a connector, a sliding member, a spring, two protrusions, and two locking members. The connector has a rectangular groove, two protrusions, and two through holes. The two protrusions are symmetrically arranged on the connector. The two protrusions are fixedly connected to the vertical fixing rod and the horizontal fixing rod, respectively, and are slidably connected to their corresponding protrusions. Each protrusion has a locking groove. The sliding member is slidably connected to the rectangular groove. One end of the spring is fixedly connected to the sliding member, and the other end of the spring is fixedly connected to the connector. The locking member is slidably connected to its corresponding through hole and is placed in its corresponding locking groove. The sliding member has two grooves that fit the two locking members.

[0007] The sliding member includes a sliding rod and a force-applying block. The sliding rod is slidably connected to the rectangular groove and fixedly connected to the end of the spring away from the connecting member. The force-applying block is fixedly connected to the sliding rod and has an anti-slip groove.

[0008] The adjustment handle also includes a fixing strap, which has a hook side and a fleece side. The fixing strap secures the sweat-absorbing band to the handle assembly through the hook side and the fleece side.

[0009] The adjustment handle further includes several protrusions, which are all disposed on the handle assembly and are evenly distributed along the axial center line of the handle assembly.

[0010] The horizontal fixing rod also has a rounded corner structure, which is used to prevent damage to the seat during installation.

[0011] This utility model provides an adjusting handle. In practical use, when the vertical and horizontal fixing rods are damaged, only individual replacements are needed. Specifically, by pushing the sliding member, the groove is aligned with the through hole. Then, the protrusion on the damaged vertical or horizontal fixing rod is removed from the corresponding groove. During removal, the protrusion holds the locking member in place within the corresponding groove. After removal, the protrusion on the new vertical or horizontal fixing rod is aligned with the corresponding groove and pushed to the designated position. At this time, the locking member is still in the groove. After pushing until the locking groove aligns with the through hole, the sliding member is released. The spring returns to its original position, causing the sliding member to return to its original position. The sliding member holds the locking member in the locking groove to lock the protrusion. This method solves the technical problem in the prior art where the vertical and horizontal fixing rods are connected by welding, resulting in the need to discard and replace the entire rod if any component is damaged, leading to poor practicality.

The aforementioned solution solves the technical problem in the prior art where the vertical fixing rod 1 and the horizontal fixing rod 2 are connected by welding, resulting in the need to discard and replace the entire component if any part is damaged, which leads to poor practicality.

[0021] In this specific embodiment, the handle assembly 3 is connected to the horizontal fixing rod 2, the handle assembly 3 is provided with a sweat-absorbing band, and the horizontal fixing rod 2 has a mounting hole 12.

[0022] The connector 4 has a rectangular groove 13, two protrusions 14, and two through holes 15. The two protrusions 14 are symmetrically arranged on the connector 4. Two protrusions 6 are fixedly connected to the vertical fixing rod 1 and the horizontal fixing rod 2, respectively, and the two protrusions 6 are slidably connected to the corresponding protrusions 14. Each protrusion 6 has a locking groove 16. The sliding member is slidably connected to the rectangular groove 13. One end of the spring 5 is fixedly connected to the sliding member, and the other end of the spring 5 is fixedly connected to the connector 4. The locking member 7 is slidably connected to the corresponding through hole 15, and the locking member 7 is placed in the corresponding locking groove 16. The sliding member has two grooves 17 that are adapted to the two locking members 7. In actual use, if the vertical fixing rod 1 and the horizontal fixing rod 2 are damaged, only one needs to be replaced. Specifically, by pushing the sliding member, the grooves are... Align 17 with the through hole 15, and then remove the protrusion 6 on the damaged vertical fixing rod 1 or the horizontal fixing rod 2 from the corresponding groove 14. During the removal process, the protrusion 6 will hold the locking member 7 in the corresponding groove 17 to wait. After removal, align the protrusion 6 on the new vertical fixing rod 1 or the horizontal fixing rod 2 with the corresponding groove 14 and push it to the designated position. At this time, the locking member 7 is still in the groove 17. After pushing it until the locking groove 16 is aligned with the through hole 15, release the sliding member. At this time, the spring 5 resets and drives the sliding member to reset. The sliding member holds the locking member 7 in the locking groove 16 to lock the protrusion 6. This method solves the technical problem in the prior art that the vertical fixing rod 1 and the horizontal fixing rod 2 are connected by welding, which means that if any part is damaged, the whole part must be discarded and replaced, resulting in poor practicality.

[0023] Secondly, the slide rod 8 is slidably connected to the rectangular groove 13, and the slide rod 8 is fixedly connected to the end of the spring 5 away from the connector 4.

[0025] Furthermore, several of the protrusions 11 are provided on the handle assembly 3 and are evenly distributed along the axial center line of the handle assembly 3. By providing several of the protrusions 11, the protrusions 11 can provide an anti-slip effect for the handle assembly 3.

[0026] Furthermore, the horizontal fixing rod 2 also has a rounded corner structure 21, which is used to prevent damage to the seat during installation.

[0027] In the application of this utility model's adjusting handle, when the vertical fixing rod 1 and the horizontal fixing rod 2 are damaged, only one needs to be replaced. Specifically, by pushing the sliding member, the groove 17 is aligned with the through hole 15. Then, the protrusion 6 on the damaged vertical fixing rod 1 or the horizontal fixing rod 2 is removed from the corresponding groove 14. During the removal process, the protrusion 6 will press against the locking member 7 and remain in the corresponding groove 17. After removal, the new vertical fixing rod 1 or the horizontal fixing rod 2 is then installed. The protrusion 6 is aligned with the corresponding groove 14 and pushed to the designated position. At this time, the locking member 7 is still located in the groove 17. After pushing until the locking groove 16 is aligned with the through hole 15, the sliding member is released. At this time, the spring 5 returns to its original position, causing the sliding member to return to its original position. The sliding member holds the locking member 7 against the locking groove 16, thus locking the protrusion 6. This method solves the technical problem in the prior art where the vertical fixing rod 1 and the horizontal fixing rod 2 are connected by welding, which means that if any part is damaged, the entire part must be discarded and replaced, resulting in poor practicality.
