Description

Technical Field

[0001] This utility model relates to the technical field of handrail light strip structure, and in particular to a structure for automatically illuminating the handrail light strip of an emergency rescue slide. Background Technology

[0002] Aircraft rescue slides are emergency escape facilities on aircraft, mainly used to evacuate passengers and crew members in emergency situations, enabling them to safely evacuate from the aircraft to the ground in a very short time.

[0003] These slides are usually hidden in the aircraft door and are folded in the open, making them inconspicuous. However, in emergencies, such as when the plane makes an emergency landing, when the normal door cannot be opened, or when there is a fire, the flight attendants will quickly open the door, the slide pack will detach, and the internal inflation system will quickly inflate it to form a huge slide, providing passengers with a safe and fast evacuation route.

[0004] Handrail light strips are typically installed on handrails in places such as stairs, corridors, and slides to provide lighting and guidance. Installing handrail light strips on rescue slides can improve rescue efficiency and safety.

[0005] The existing rescue slide handrail light strips cannot automatically light up when the rescue slide pops out, which is inconvenient to use. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this invention provides a structure for automatically illuminating the light strip on the handrail of an emergency rescue slide. This structure enables the light strip to illuminate automatically when the emergency rescue slide deploys, making it convenient to use.

[0007] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: A structure for automatically illuminating a light strip on the handrail of an emergency rescue slide includes a light body, which includes a top cover, a micro switch, and a switch slot. The micro switch includes a body, a spring plate on the top of the body, one end of the spring plate being connected to the body and the other end being curved upwards, a contact point being provided on the upper surface of the body corresponding to the position of the curved end of the spring plate, and pins being evenly provided on the lower surface of the body. The switch slot has a first insertion slot, and a second insertion slot is provided above the first insertion slot and communicating with it. The lower end face of the switch slot has an exposed groove, which communicates with the first insertion slot. The body is slidably connected to the first insertion slot. The spring plate is located in the second insertion slot. The pin protrudes from the exposed groove. The upper end of the switch slot has a connecting groove, which communicates with the second insertion slot. The upper end of the connecting groove has a threaded rope, which is engaged with the connecting groove through a connecting part. The threaded rope presses against the spring plate. The switch slot is provided with an upper cover on the outside. The upper cover includes a base and a ring. The upper surface of the base is provided with a ring. The switch slot and the micro switch are engaged with the upper cover.

[0008] As an improvement, the rope threading includes a pressure plate and a clamping cylinder. The clamping cylinder is located at the lower end of the side of the pressure plate. The connecting part includes a clamping cylinder and a limiting protrusion. The upper inner surface of the connecting groove is provided with a limiting protrusion, and the clamping cylinder is located below the limiting protrusion.

[0009] As an improvement, the middle section of the limiting protrusion is provided with an opening, through which the pressure plate passes.

[0010] As an improvement, the cross-section of the limiting protrusion is arc-shaped.

[0011] As an improvement, the base is provided with a limiting groove 1 and a limiting groove 2, the limiting groove 1 and the limiting groove 2 are connected to each other and perpendicular to each other, the micro switch is slidably connected to the limiting groove 1, the switch slot is slidably connected to the limiting groove 2, the upper end of the limiting groove 2 is provided with a limiting groove 3, and the lower end of the connecting groove is slidably connected to the limiting groove 3.

[0012] As an improvement, a snap-fit ​​block is provided at the lower end of the side of the switch slot, the opposite side of the snap-fit ​​block is an inclined surface, and a snap-fit ​​groove is provided on the inner surface of the second limiting groove, and the snap-fit ​​block snaps into the snap-fit ​​groove.

[0013] Compared to traditional technologies, the advantages of this utility model are: The lights are evenly distributed on both sides of the upper part of the aircraft rescue slide. When the aircraft rescue slide is deployed, the rope is pulled. At this time, the spring of the micro switch changes from being in contact with the contact to being separated from the contact. The micro switch is then turned on, and the connected battery and circuit are connected, and the light strip lights up. It is convenient and quick to use. Attached Figure Description

[0018] Example 1 Combined with appendix Figure 1-5 The micro switch includes a body 2, a spring plate 3 is provided on the upper part of the body 2, one end of the spring plate 3 is connected to the body 2, and the other end is bent upward. A contact 4 is provided on the upper end surface of the body 2 at the position corresponding to the bent end of the spring plate 3, and pins 5 are evenly provided on the lower end surface of the body 2. The switch slot 1 is provided with a first insertion slot 6, and a second insertion slot 7 is provided above the first insertion slot 6 and communicates with it. The lower end face of the switch slot 1 is provided with an exposed slot 8, which communicates with the first insertion slot 6. The body 2 is slidably connected to the first insertion slot 6. The spring plate 3 is located in the second insertion slot 7. The pin 5 protrudes from the exposed slot 8. The upper end of the switch slot 1 is provided with a connecting slot 9, which communicates with the second insertion slot 7. The upper end of the connecting slot 9 is provided with a threaded rope 10, which is engaged with the connecting slot 9 through a connecting part. The threaded rope 10 presses against the spring plate 3. The switch slot 1 is provided with an upper cover on its outer side. The upper cover includes a base 11 and a ring 12. The upper surface of the base 11 is provided with the ring 12. The switch slot 1 and the micro switch are engaged with the upper cover. The base 11 is provided with a first limiting groove 15 and a second limiting groove 16. The first limiting groove 15 and the second limiting groove 16 are connected to each other and perpendicular to each other. The micro switch is slidably connected to the first limiting groove 15. The switch slot 1 is slidably connected to the second limiting groove 16. The upper end of the second limiting groove 16 is provided with a third limiting groove 17. The lower end of the connecting groove 9 is slidably connected to the third limiting groove 17.

[0019] In use, insert the micro switch body 2 into the insertion slot 6 of the switch slot 1, insert the spring plate 3 at the upper end of the body 2 into the insertion slot 7, and expose the pin 5 at the lower end of the body 2 from the exposure slot 8. At this time, the micro switch can slide in the switch slot 1, and both ends of the micro switch are exposed from the switch slot 1. Place the rope 10 above the spring plate 3 of the micro switch, and place the pressure plate 10 in the connecting slot 9 at the upper end of the switch slot 1. The position of the pressure plate 20 is limited by the connecting part, and the pressure plate 20 is pressed tightly on the spring plate 3. At this time, the spring plate 3 is in contact with the contact 4. Place the connected pressure plate 20, micro switch and switch slot 1 into the upper cover.
