Description

Technical Field

[0001] This utility model belongs to the field of aviation repair, and in particular is a protective device for antenna panels. Background Technology

[0002] The antenna panel is an important component of aircraft radar. Currently, a straw hat-shaped plastic cover is used in repairs. During protection, nylon cable ties are used to tie the cover to the antenna panel, and the resulting hollow area can only protect the antenna installed in the center of the antenna panel.

[0003] However, the existing straw hat-shaped plastic cover, due to its thin walls and poor rigidity of the plastic material, can only prevent the antenna mounted on the panel from colliding, offering no protection to the area around the antenna panel. Furthermore, this type of cover uses nylon straps to secure the antenna panel, which cannot provide complete fixation. Bumps during transportation can cause displacement between the antenna panel and the cover, resulting in scratches on the protective film. Additionally, when handling the antenna panel, the existing antenna protective cover allows for direct handling by hand, and residual sweat, oil, and other substances from the hands can contaminate the protective film. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for antenna panels. This device has a simple structure, high strength, light weight, and aesthetically pleasing design. The ingenious connection structure between the device and the product ensures reliable installation and convenient, quick operation. In addition to its protective function, the device also functions as a handling handle, a rear repair bracket, and a warning label.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a protective device for an antenna panel, characterized in that it includes a connecting rod, an inner ring, an outer ring, a special interface plate, and a connecting fastening assembly; the inner ring and the outer ring are fixedly connected by evenly distributed connecting rods, the special interface plate is fixedly connected to the outer ring, and the antenna panel is mounted on the special interface plate by the connecting fastening assembly.

[0006] Compared with the prior art, the significant advantages of this utility model are:

[0007] 1. This utility model provides a protective device for an antenna panel. By connecting and fastening components to the antenna panel, the resulting limiting space can not only effectively protect the antenna installed on the antenna panel, but also provide rigid protection for the periphery of the panel.

[0008] 2. This utility model provides a protective device for an antenna panel. In addition to providing rigid protection, the outer ring can also serve as a handle for moving the antenna panel, and can be gripped from all sides.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 5 As shown, a protective device for an antenna panel includes a connecting rod 1, an inner ring 2, a shaping rod 3, an outer ring 4, a special interface plate 5, a flexible pad 6, a protective sleeve 7, and a connecting fastening assembly.

[0021] The inner ring 2 and the outer ring 4 are fixedly connected by evenly distributed connecting rods 1. The connecting rods 1, the inner ring 2 and the outer ring form a conical frame structure. The inner ring 2 is fixedly installed with shaping rods 3, which can achieve different shapes. The connecting rods 1, the inner ring 2, the shaping rods 3 and the outer ring 4 are all made of thin-walled hollow aluminum tubes, which can significantly reduce the weight while ensuring sufficient rigidity.

[0022] The dedicated interface board 5 is fixedly welded to the outer ring 4; the dedicated interface board 5 has round holes machined on it, and the distribution of the dedicated interface board 5 and its round holes is set according to the position of the mounting holes 9-2 on the antenna panel 9.

[0023] The connection and fastening assembly includes: a fastening nut 8, a screw seat 10, a screw 11, and a fastening screw 12;

[0024] The screw seat 10 is fixedly mounted on the dedicated interface plate 5 by screws 11. The screw seat 10 is mounted on one side of the dedicated interface plate 5 (the side closer to the inner ring 2). The screw seat 10 has a stepped hole machined on it. The stepped hole is divided into a smooth section and a threaded section. When the threaded section engages with the thread of the stud at the top of the fastening screw 12, it is used to position the axial position of the fastening screw 12. This not only prevents the fastening screw 12 from falling off the screw seat 10 in a free state, but also allows the fastening screw 12 to be fixed on the screw seat 10 during the initial installation of the device, avoiding interference caused by the fastening screw 12 protruding from the mounting surface.

[0025] The antenna panel 9 is provided with reinforcing ribs 9-1 and mounting holes 9-2;

[0026] The fastening nut 8 is installed on the reverse side of the antenna panel 9. The fastening nut 8 has a stepped structure with a threaded hole machined in the center. The threaded hole mates with the thread of the stud at the tip of the fastening screw 12. The outer diameter of the small end of the step of the fastening nut 8 is the same as the diameter of the mounting hole 9-2 on the antenna panel 9, used to install the fastening nut 8 into the mounting hole 9-2; Figure 5As shown, a straight-edged notch is machined on the outer circumference of the large end of the step of the fastening nut 8 to avoid the reinforcing rib 9-1 and to prevent the fastening nut 8 from rotating when the fastening screw 12 is screwed into the fastening nut 8. The fastening nut 8 is made of polytetrafluoroethylene material, which has self-lubricating and wear-resistant properties.

[0027] The fastening screw 12 consists of three parts: a stud, a middle rod, and a base. The stud is threaded for connection with the fastening nut 8. The middle rod has a diameter smaller than the minor diameter of the stud's thread, allowing it to quickly move to the engagement position after the fastening screw 12 disengages from the screw seat 10. The outer surface of the base is knurled to reduce the engagement resistance at the end of the fastening screw 12, allowing for manual tightening without the need for external tightening tools such as wrenches, simplifying the operation. The step between the base and the middle rod further reduces the engagement resistance at the end of the fastening screw 12.

[0028] The flexible pad 6 is bonded and fixed to the other side of the round hole on the dedicated interface 5 (between the interface board 5 and the antenna panel 9), so that the antenna panel 9 and the dedicated interface board 5 do not directly contact each other, forming a flexible protection.

[0029] The protective sleeve 7 is fixedly wrapped around the outer ring 4. The protective sleeve 7 includes a polyurethane foam tube 7-1 and electrical tape 7-2. The polyurethane foam tube 7-1 is cut open from the side and wrapped around the outer ring 4, then secured with electrical tape 7-2 wrapped around its outer side. The electrical tape 7-2 is yellow and black, alternately wrapped around the outside of the polyurethane foam tube 7-1 with consistent spacing. The protective sleeve 7 not only effectively utilizes the cushioning effect of the polyurethane foam tube, but the alternating yellow and black electrical tape also serve as a warning and reminder.

[0030] The method of using the protective device for the antenna panel is as follows:

[0031] Step 1: Install the four fastening nuts 8 into the mounting holes 9-2 on the back of the antenna panel. (Specifically: Since the outer diameter of the small end of the fastening nut 8 is the same as the diameter of the mounting hole 9-2, during installation, align the straight edge notch of the fastening nut 8 with the reinforcing rib 9-1 from the back of the antenna panel 9, and push the outer diameter of the small end of the fastening nut 8 into the mounting hole 92. The fastening nut will not fall off under the action of friction.)

[0032] Step 2: Screw the fastening screw 12 onto the thread of the screw seat 10.

[0033] Step 3: Grasp the outer ring 4 and place the protective device on the antenna panel 9, then rotate the fastening screw 12 to disengage it from the thread of the screw seat 10.

[0034] Step 4: Push the fastening screw 12 forward to connect it to the fastening nut 8 mounted on the antenna panel.

[0035] Step 5: After connecting and securing all four positions, the installation of the protective device is complete.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
