Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment, and particularly to a structure for in-situ replacement installation of equipment and capable of ensuring the installation direction. Background Art

[0002] In-situ replacement means that a new device is installed using the installation holes of an old device. For a lighting fixture used in an aircraft, the old device in its original position has no installation direction requirement, and the installation holes are randomly arranged on the circumference. However, when replacing the old device with a new lighting fixture, there is an installation direction requirement and it needs to be installed using the original holes. The existing technical solutions usually adopt re-drilling or riveting the mounting plate parts. When the installation hole positions and directions of the lighting fixture are exactly the same as those on the aircraft, in-situ replacement installation can be carried out. However, when the installation hole positions are deviated and the optical axis (the light emitted by the lighting fixture diffuses in a conical shape with the light source as the vertex, and the symmetry axis of this cone is called the optical axis) direction cannot be guaranteed, in-situ replacement installation cannot be carried out, and re-drilling or riveting the mounting plate parts is required; when the deviation distance of the hole position is less than or equal to the hole diameter, neither drilling nor riveting the mounting plate can be implemented. Summary of the Invention

[0003] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to provide a structure for in-situ replacement installation of equipment and capable of ensuring the installation direction.

A direction mark is engraved on the equipment body, and a toothed ring is fixed. The toothed ring is sleeved with the installation adjustment ring. A groove is provided on the inner wall of the installation adjustment ring, and an adjustment plate is fixed in the groove. A sector rack that is snap-fitted into the toothed ring is provided on one side of the adjustment plate close to the ring hole. Installation holes corresponding to the screw holes are provided on the installation adjustment ring; Screws are fixed in the screw holes and pass through the installation holes, and the screws fixedly connect the installation adjustment ring and the bottom plate; The equipment body is fixed inside the toothed ring.

A plurality of screw holes 10 are provided thereon. A direction mark is engraved on the device body 2, and a toothed ring 3 is fixed. The toothed ring 3 is sleeved with the installation adjustment ring 4. A groove 6 is provided on the inner wall of the installation adjustment ring 4. An adjustment plate 7 is fixed in the groove 6. A sector rack 8 that engages and embeds the toothed ring 3 is provided on one side of the adjustment plate 7 close to the ring hole. Installation holes 5 corresponding to the screw holes 10 are provided on the installation adjustment ring 4. Screws 13 passing through the installation holes 5 are fixed in the screw holes 10. The screws 13 fixedly connect the installation adjustment ring 4 and the bottom plate 1. The device body 2 is fixed in the toothed ring 3.

[0024] In this embodiment, a limiting plate 11 flush with its top surface is provided in the ring hole of the installation adjustment ring 4. The limiting plate 11 abuts against the top of the toothed ring 3.

[0025] In this embodiment, the sector rack 8 on the installation adjustment ring 4 and the toothed ring 3 on the device body 2 are engaged at any angle.

[0026] In this embodiment, there are a plurality of screw holes 10.

[0027] In this embodiment, a plurality of screws 9 are fixedly connected between the adjustment plate 7 and the installation adjustment ring 4.

[0028] In this embodiment, the top surface of the installation adjustment ring 4 is flush with the top surface of the device body 2.

[0029] In this embodiment, a plurality of annular load-reducing grooves 12 are provided at the bottom of the installation adjustment ring 4.

[0030] In this embodiment, the replacement process of the in-situ replacement structure of the present invention includes the following steps: S1 Place the device body 2; place the device body 2 within the surrounding range of the screw holes 10, and adjust the device body 2 so that its direction is aligned with the mark; S2 Hole position configuration; align the positions of the installation holes 5 and the screw holes 10, and lower the installation adjustment ring 4 so that the sector rack 8 engages and fixes with the toothed ring 3; S3 Install the screws; screw the screws 13 into the screw holes 10 corresponding to the positions of the installation holes 5.

[0031] Working principle: The lamp of the present invention is designed with a structure in which the installation adjustment ring 4 and the device body 2 are separated. An adjustment plate 7 is designed on the inner side of the installation adjustment ring. A circumferential toothed ring 3 is designed along the circumference on the outer side of the upper part of the device body 2. When installing the lamp, first determine the direction of the device body 2, then align the installation holes 5 of the installation adjustment ring 4 with the screw holes 10 on the aircraft and press down and install screws 13. Then, the sector rack 8 on the adjustment plate 7 is embedded into the circumferential toothed ring 3 on the device body 2, and the installation adjustment ring 4 presses and fixes the device body 2 so that it cannot rotate; thus, the problem that the lamp direction adjustment does not match the original installation holes during in-situ replacement installation is solved.

[0032] On this basis, a limit plate 11 is provided to position the installation adjustment ring 4 and play a role in shielding and protecting the toothed ring 3; the present invention is provided with screws 9 to fix the adjustment plate 7, and the installation direction of the device body 2 is fixed by the engagement of the sector rack 8 and the toothed ring 3.

[0033] Generally speaking, the present invention is provided with structures such as an installation adjustment ring 4, an adjustment plate 7, a sector rack 8, and a toothed ring 3. By designing a sector rack and toothed ring structure, the problem of in-situ replacement installation of the lamp can be solved without cumbersome processes such as re-drilling and riveting, and the problem that the lamp points to a specific direction after installation can be ensured; in the present invention, the structure of the screw 13 is adopted to install corresponding to the screw hole 10 and the installation hole 5, and here the screw 13 can also be replaced with a rivet.
