Description

Technical Field

[0001] This utility model relates to aircraft maintenance equipment, and in particular to a quick-installation device for a protective cover for an airborne optoelectronic radar radome. Background Technology

[0002] The radome of the aircraft's electro-optical radar module is made of optical glass. Exposure to ultraviolet light or external scratches can affect the radar's performance. Therefore, a protective cover is used to protect the radome. During installation, a threaded screw is screwed onto the threaded base of the electro-optical radar module, covering the radome. This requires a high degree of precision in the alignment between the screw on the protective cover and the threaded hole on the radar module's base. Only with high precision can the screw be successfully screwed into the threaded hole. However, the inside of the protective cover is not visible, making it impossible for operators to accurately determine the position of the screw's mating end within the cover. Furthermore, misalignment is likely after passing through the cover, making manual alignment impossible. Therefore, the operator must continuously align the screw during the mating process, resulting in a difficult and time-consuming installation. Utility Model Content

The docking component is installed on the base of the opto-radar module. The docking component includes a docking seat installed on the opto-radar module and an inner nut that is threadedly engaged with the screw. The docking seat has a movable cavity for placing the inner nut. The bottom of the movable cavity has a positioning groove for the inner nut, the diameter of which is larger than the diameter of the inner nut. A movable gap is provided between the inner wall of the movable cavity and the outer wall of the inner nut to facilitate the left-right movement of the inner nut. The inner nut is installed in the movable cavity by a limiting component. The limiting component includes a protrusion on the outer wall of the inner nut and a groove that slides with the protrusion. The groove is opened on the inner wall of the movable cavity, with the groove opening facing the inner nut. The top of the groove has an inlet and outlet for the protrusion to enter the groove.

[0005] The technical problem to be solved by this utility model can also be achieved by the following technical solution: an inner inclined surface is provided at the interface of the inner nut to guide the screw to slide toward the center of the inner nut.

[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: two protrusions are provided, symmetrically arranged on the outer wall of the inner nut, and a groove is provided around the circumference of the mating seat.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the docking seat is a tubular seat body, the inner nut is embedded in the tubular seat body, and one end of the tubular seat body is provided with a docking interface opposite to the screw.

[0017] Reference Figure 1-4 A quick-installation device for a protective cover for an airborne opto-radar radome, the device comprising a protective cover 1 covering the airborne opto-radar radome 2, a screw 4 passing through the protective cover 1, and a docking component that quickly docks with the screw 4, the docking component being installed on the opto-radar module base 3. The docking component includes a docking seat 5 fixed on the base 3 of the photoelectric radar module and an inner nut 8 threadedly engaged with the screw 4. The docking seat 5 has a movable cavity 6 for placing the inner nut 8. The bottom of the movable cavity 6 has a positioning groove 7 for the inner nut 8. The diameter of the positioning groove 7 is slightly larger than the diameter of the inner nut 8. There is a movable gap between the inner wall of the movable cavity 6 and the outer wall of the inner nut 8 to facilitate the left and right movement of the inner nut. The inner nut 8 is installed in the movable cavity 6 through a limiting component. A nut is provided on the top of the screw to realize the installation of the protective cover. The limiting component includes a protrusion 9 on the outer wall of the inner nut 8 and a groove 10 that slides with the protrusion 9. The groove 10 is opened on the inner wall of the movable cavity 6, and the groove opening of the groove 10 is set facing the inner nut 8. The top of the groove 10 is provided with an inlet and outlet 14 for the protrusion 9 to enter the groove.

[0018] An inner inclined surface 11 is provided at the interface of the inner nut 8 to guide the screw to slide towards the center of the inner nut, thereby further improving the docking efficiency between the screw 4 and the inner nut 8.

[0019] Two protrusions 9 are provided, symmetrically arranged on the outer wall of the inner nut 8. The groove 10 is provided around the circumference of the mating seat 5 to avoid reducing the docking efficiency between the screw and the inner nut due to structural asymmetry.

[0020] The docking seat 5 is a tubular seat body. The shape of the tubular seat body is adapted to the inner nut, and the inner nut can be embedded into the tubular seat body. The structure is simple and the modification is more convenient.

[0021] The outer wall of the docking seat 5 is provided with an external thread 13 that engages with the threaded hole on the base of the photoelectric radar module. The docking port of the docking seat 5 is provided with two positioning ports 14, symmetrically arranged around the center of the docking seat 5, to facilitate screwing the docking seat 5 into the threaded hole of the base. When it is necessary to install or remove the docking seat, a tool is placed at the two positioning ports 14, and the tool is rotated to install or remove the docking seat from the base of the photoelectric radar module.

[0022] A protective layer is laid flat on the inner wall of the protective cover 1 to prevent the protective cover from scratching the fairing. The protective layer can be a soft cloth, rubber sheet, or sponge sheet, or a sheet made of any soft material. The width of the movable gap is smaller than the diameter of the screw to prevent the screw from being inserted into the movable gap during docking and affecting subsequent installation.

[0023] The working process or working principle of the quick-installation device for the protective cover of the airborne optoelectronic radar radome described in this utility model is as follows: During installation, the mating component described in this utility model is first installed into the threaded hole on the photoelectric radar base through the external thread on the mating seat. Then, the protective cover 1 is placed on the rectifier 2 and fixed to the photoelectric radar module base 3 by the mating component and the screw. When installing the screw, the screw 4 is inserted through the hole on the protective cover and extends all the way to the mating component. Since the threaded hole of the mating is not directly visible, the screw 4 has a slight offset during the actual connection process. The screw 4 offsets to the movable gap, and the mating end of the screw 4 abuts against the inner inclined surface 11 of the inner nut 8. Continue rotating screw 4. Screw 4 moves closer to the center of inner nut 8 along inner inclined surface 11. At the same time, inner nut 8 rotates or swings actively in movable cavity 6 under the push of screw 4. Continue rotating screw 4. During the rotation of screw 4, the inner nut 8 continuously adjusts the position of screw 4 to automatically align the center of the inner nut with the center of the screw 4 until the screw 4 is fully connected, thus enabling the rapid installation of the protective cover 1.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
