Description

Technical Field

[0001] This utility model belongs to the field of aerospace structural design technology and relates to a multifunctional quick-opening cover. Background Technology

[0002] External attachments are typically large antenna mounting platforms on the back of the fuselage. To facilitate the maintenance of internal equipment, various maintenance covers are usually provided on the outer surface. These covers are generally divided into equipment maintenance covers and personnel access covers, depending on their use. When closed, the covers maintain the structural integrity of the external attachment pneumatically; when open, they provide access for equipment inspection and maintenance.

[0003] Currently, existing access covers for external attachments typically consist of a cover plate, frame, reinforcing components, seals, and fasteners connecting to the surrounding structure. Once opened, the cover is suspended externally by a connecting rope. Because the external attachment is located above the machine body, maintenance personnel must access it through the access cover at the bottom. During maintenance, personnel must stand below the external attachment and reach up to remove the fasteners around the cover, which is time-consuming, laborious, and prone to fasteners falling and scratching the machine body. Furthermore, accidental collisions must be prevented when the cover is open, posing a safety hazard. Once personnel are inside, the open cover provides no protection. Utility Model Content

[0019] To make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model embodiment will be described in more detail below in conjunction with the utility model embodiment. In the examples, the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The described embodiments are part of the embodiments of the utility model, not all embodiments. The following description of the described embodiments is exemplary and is intended to explain the utility model, and cannot be understood as limiting the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model. The following will be described in detail in conjunction with the embodiments of the utility model.

[0020] The utility model provides a multifunctional quick opening import and export cover assembly, including machine adds mouth frame, machine adds cover plate, hinge joint, mouth cover lock, handle, draw tape, gas spring assembly. One side hinge joint is arranged in mouth frame one side, the other side hinge joint is connected with mouth cover, one end of gas spring is fixed on mouth frame, the other end is connected with mouth cover through joint, handle is arranged in the middle part of the opposite side of hinge pivot outside mouth cover, draw tape and two hand -open mouth cover locks are arranged inside, and draw tape is used for personnel to open mouth cover inside. Through reasonable setting hinge center position, gas spring connecting point position and gas spring specification, mouth cover is opened or closed automatically at certain opening angle, and after opening, mouth cover can maintain static state on one side under the action of gas spring, and after closing, can realize self -locking. After personnel enters, closes mouth cover, guarantees personnel safety.
