[0001] This utility model belongs to the field of aircraft maintenance technology, and more specifically, it relates to an auxiliary lighting device for engine maintenance. Background Technology

[0002] Lighting devices are often needed for the maintenance of aircraft engines and their accessories (such as generators) because aircraft are usually maintained at night and the maintenance area is relatively narrow and dark. Lighting devices can illuminate the parts that need to be maintained, making maintenance operations easier. Lighting devices are usually attached to a mounting plate at a suitable position in the corresponding part by clamping.

[0003] The existing attachment fixtures for lighting devices used in aircraft maintenance rely entirely on threads to adjust the distance between the two clamps. This results in a slow adjustment rate when large-span adjustments are needed, reducing the maintenance efficiency of aircraft engines and their components, and making them less flexible and practical.

[0023] As attached Figure 1 To be continued Figure 6 As shown:

[0024] Example 1: This utility model provides an auxiliary lighting device for engine maintenance, including a lighting component 1 and an attachment component 2. The lighting component 1 is fixedly mounted on a plate at a suitable position near the aircraft engine via the attachment component 2. The lighting component 1 includes a lighting fixture 101 and a shaping rod 102, with the lighting fixture 101 fixedly mounted on one end of the shaping rod 102. The attachment component 2 includes a fixed support plate 201, a track column 202, a movable support plate 203, an auxiliary support seat 204, a positioning block 205, and an operating... The operating rod 206 and the track column 202 are fixedly installed on the top of the fixed support plate 201, and the movable support plate 203 is inserted into the outside of the track column 202. The auxiliary support seat 204 is inserted into the outside of the track column 202 and is located on the top of the movable support plate 203. The other end of the shaping rod 102 is fixedly installed on the top of the movable support plate 203. The positioning block 205 is inserted into the inside of the auxiliary support seat 204, and the operating rod 206 is rotatably connected to the inside of the movable support plate 203.

[0025] In this embodiment, the cross-sectional shape of the track column 202 is "I". This design can limit the movement trajectory of the movable support plate 203 and the auxiliary support seat 204 during adjustment, switching and other actions, and avoid the phenomenon of skewness or twisting that causes the device to jam and fail, thus ensuring stable use.

[0026] In this embodiment, the top of the movable support plate 203 is provided with a guide plate, and the inside of the guide plate is provided with a guide groove. The side of the positioning block 205 is provided with a guide rod 2051, which is inserted into the inside of the guide groove. In use, the attachment component 2 has two usage modes, namely a locking mode and a free mode. The two modes can be switched and adjusted by adjusting the spacing between the movable support plate 203 and the auxiliary support base 204.

[0027] In this embodiment, the guide groove consists of a positioning groove 2031 and a release groove 2032. The groove direction of the positioning groove 2031 is parallel to the long side direction of the track column 202, and the release groove 2032 is an inclined groove. The bottom of the positioning groove 2031 is connected to the top of the release groove 2032. The side of the track column 202 is provided with a positioning tooth groove 2021, and the side of the positioning block 205 is provided with a positioning tooth block 2052. When the guide rod 2051 is located inside the positioning groove 2031, the positioning tooth block 2052 is inserted into the positioning tooth groove 2021. In use, when the movable support plate 203 and the auxiliary support seat 204 are in contact with each other, the attachment component 2 is in a free mode. In this mode, the guide rod 205... 1 is located at the bottom end of the release groove 2032, so that the positioning tooth block 2052 disengages from the interior of the positioning tooth groove 2021. At this time, both the auxiliary support base 204 and the movable support plate 203 can move freely up and down outside the track column 202, thereby enabling quick adjustment and change of the working distance between the fixed support plate 201 and the movable support plate 203. The adjustment is convenient and can be adapted to positioning and disassembly on attachment plates of different thicknesses. The operating rod 206 has threads on the outside of its body, and the operating rod 206 is screwed into the interior of the auxiliary support base 204 through the thread. In free mode, rotating the operating rod 206 moves the auxiliary support base 204 away from the movable support plate 203 to switch the attachment component 2 to the locking mold. In this configuration, when the operating lever 206 rotates clockwise (with the direction of rotation of the operating lever 206 being positive when the auxiliary support seat 204 and the movable support plate 203 are moving away from each other), the operating lever 206 can drive the auxiliary support seat 204 to move away from the movable support plate 203 via the lever thread. During this process, the guide rod 2051 can drive the positioning block 205 to move under the guidance of the release groove 2032, so that the positioning tooth block 2052 is engaged in the positioning tooth groove 2021 at the corresponding position. Thus, the auxiliary support seat 204 cannot move up and down outside the track column 202 afterward, providing a support point for the movable support plate 203. After the operating lever 206 continues to rotate clockwise, the guide rod 2051 can enter the positioning groove. The interior of the slot 2031 does not obstruct the mutual distancing movement between the auxiliary support base 204 and the movable support plate 203. Subsequently, the movable support plate 203 continues to move and cooperates with the fixed support plate 201, so that the attachment component 2 is clamped and positioned on the attachment plate. The continuously rotating operating lever 206 can continuously apply the positioning locking (clamping) force, which is convenient to operate and flexible to use. In the locking mode, the attachment component 2 can be switched to the free mode for use by reversing the operating lever 206, which is convenient for subsequent installation and removal on other attachment plates. During the installation and removal operation, it is only necessary to change the distance between the auxiliary support base 204 and the movable support plate 203. The required adjustment distance is very small, the installation and removal are quick, and the maintenance efficiency is improved.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this invention, after the lighting component 1 is fixed in a suitable position by the attachment component 2, the lighting fixture 101 can be used to illuminate the maintenance area. The attachment component 2 has two operating modes: a locking mode and a free mode. The two modes can be switched and adjusted by adjusting the spacing between the movable support plate 203 and the auxiliary support base 204. When the movable support plate 203 and the auxiliary support base 204 are in contact with each other, the attachment component 2 is in the free mode. In this mode, the guide rod 2051 is located at the bottom end of the release groove 2032, and the positioning tooth block 2052 disengages from the inner part of the positioning tooth groove 2021. In this configuration, both the auxiliary support base 204 and the movable support plate 203 can move freely up and down outside the track column 202, allowing for quick adjustment and change of the spacing between the fixed support plate 201 and the movable support plate 203. This convenient adjustment allows for positioning and installation on attachment plates of varying thicknesses. In free mode, rotating the operating lever 206 moves the auxiliary support base 204 away from the movable support plate 203 to switch the attachment assembly 2 to the locking mode. The direction of rotation of the operating lever 206 is considered positive when the auxiliary support base 204 and the movable support plate 203 move away from each other. When the operating lever 206 is turned forward, it can drive the auxiliary support seat 204 to move away from the moving support plate 203 via the screw thread. During this process, the guide rod 2051 can drive the positioning block 205 to move under the guidance of the release groove 2032, so that the positioning tooth block 2052 is engaged in the positioning tooth groove 2021 at the corresponding position. Therefore, the auxiliary support seat 204 cannot move up and down outside the track column 202, and can provide a support point for the moving support plate 203. After that, when the operating lever 206 is turned forward, the guide rod 2051 can enter the positioning groove 2031 without obstructing the auxiliary support seat 204. The support base 204 and the movable support plate 203 move away from each other, and then the movable support plate 203 continues to move and cooperate with the fixed support plate 201, so that the attachment component 2 is clamped and positioned on the attachment plate. The continuously rotating operating lever 206 can continuously apply the positioning locking (clamping) force. In the locking mode, the attachment component 2 can be switched to the free mode for use by reversing the operating lever 206, which is convenient for subsequent installation and removal on other attachment plates. During the installation and removal operation, it is only necessary to change the distance between the auxiliary support base 204 and the movable support plate 203. The required adjustment distance is very small, and the installation and removal are quick.
