[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Embodiment one: please refer to Figure 1 - Figure 4The utility model provides following technical scheme: An explosion -proof aircraft passenger cabin lighting device, fixed ring 1 outside fixedly connected with the assembly flange, and fixed ring 1 is installed in the passenger cabin through assembly flange, and fixed ring 1 passenger cabin inner wall is flush, fixed ring 1 inside screw thread connection has installation ring 2, and installation ring 2 inside snap connection has two symmetrical distribution's clamping block 3, two clamping block 3 splicing forms ball seat structure, and ball seat structure inside rotationally connected with ball joint 4, and ball joint 4 inside installation has lighting structure, installation ring 2 bottom is provided with symmetrical distribution's hand buckle groove 5, and installation ring 2 inside fixedly connected with the annular equidistance distribution's thread sleeve 6, and thread sleeve 6 forms the protrusion in installation ring 2 inboard, thread sleeve 6 inside screw thread connection has self -screwing screw 7, and installation ring 2 bottom fixedly connected with isolation ring 8, and isolation ring 8 cross section is wave -shaped structure, clamping block 3 bottom outside slidingly connected with the annular structure's engagement strip 9, and two engagement strips 9 mutually splicing form complete annular structure, and engagement strip 9 outside is equipped with equidistance distribution's positioning slot 10, and positioning slot 10 and thread sleeve 6 are aligned, and engagement strip 9 snap connection is in installation ring 2 inside, clamping block 3 top fixedly connected with the connecting ring 11, and two connecting rings 11 butt joint form closed annular structure, and the annular structure outside screw thread connection has the outer thread of positioning ring 12 cooperation.

[0027] In the process that the user uses the device, the lighting structure in the ball joint 4 is powered by the connection of the power supply connector 19 and the power supply socket 18, so that the light is emitted from the middle of the fixed ring 1. Since the lighting structure is located in the ball joint 4, and the movable sleeve 16 extends to the outside of the bottom of the isolation ring 8, the ball joint 4 can be rotated in the clamping block 3 by driving the movable sleeve 16 to rotate.

[0028] Since the two clamping blocks 3 form a ball seat, and the ball joint 4 is installed in the ball seat, the ball joint 4 can rotate in the clamping block 3 at this time, so that the output end of the lighting structure can be adjusted arbitrarily within a certain range. Since the outside of the ball joint 4 and the inside of the clamping block 3 are provided with damping, the ball joint 4 stops rotating in the clamping block 3, and the ball joint 4 will fix the orientation of the lighting structure, so as to fix the angle of the lighting structure. During the adjustment of the lighting structure, the isolation ring 8 is connected with the clamping groove ring 15 on the outside of the mounting sleeve 13, so that the isolation ring 8 will deform with the adjustment of the lighting structure.

[0029] The fixed ring 1 and the mounting ring 2 are detachable, during the installation of the device, first pull out the power connector 19 from the inside of the body, at this time the power connector 19 will be located outside the fixed ring 1, make it connected through the power socket 18 at the top of the ball joint 4 and the power connector 19, and then power the lighting structure inside the ball joint 4, after the connection of the ball joint 4, at this time the two clamping blocks 3 are wrapped outside the ball joint 4, and the positioning ring 12 is installed outside the connecting ring 11 at the top of the clamping block 3, so that the two clamping blocks 3 are spliced to form a whole.

[0030] When the clamping block 3 and the ball joint 4 are fixed, at this time the positioning groove 10 outside the clamping strip 9 is aligned with the threaded sleeve 6, and the clamping strip 9 is installed inside the mounting ring 2, at this time the protrusion formed inside the mounting ring 2 will be clamped and connected inside the positioning groove 10, and the two clamping strips 9 are spliced to form a whole through the mounting ring 2, at this time the self-tapping screw 7 is installed inside the threaded sleeve 6, the position of the clamping strip 9 inside the mounting ring 2 is fixed through the self-tapping screw 7, to prevent the clamping strip 9 from sliding up and down inside the mounting ring 2, when the mounting ring 2 and the clamping block 3 are connected, at this time the mounting ring 2 is rotated through the hand buckle groove 5 at the bottom of the mounting ring 2, until it is screwed inside the fixed ring 1, the installation of the device is completed.

[0031] During the disassembly of the device, the mounting ring 2 is rotated through the two hand buckle grooves 5 arranged at the bottom of the mounting ring 2, so that the mounting ring 2 rotates inside the fixed ring 1 until it is separated, at this time the mounting ring 2 will separate the clamping block 3, the ball joint 4, the power connector 19 and the fixed ring 1, at this time the connection between the power connector 19 and the top of the ball joint 4 is disconnected, and the rotating positioning ring 12 and the self-tapping screw 7 are taken out from the outside of the connecting ring 11 and the inside of the threaded sleeve 6 respectively, at this time the upper and lower ends of the clamping block 3 will not be restricted, so the clamping block 3 can be taken out from the inside of the mounting ring 2 and separated, at this time the ball joint 4 will be in an independent state, and then the lighting structure inside the ball joint 4 is maintained.

[0032] Example two: on the basis of example one, please refer to Figure 5 and Figure 6 , the lighting structure is also disclosed, and the specific structure is as follows: the lighting structure comprises a mounting sleeve 13 located inside the ball joint 4, the mounting sleeve 13 is fixedly connected with an LED lamp bead 14 at the top, and a clamping groove ring 15 is fixedly connected to the outside of the lower end of the mounting sleeve 13; the inside of the clamping groove ring 15 is connected with the end of the isolation ring 8 away from the mounting ring 2, and a movable sleeve 16 is slidably connected inside the mounting sleeve 13, a lens 17 is fixedly connected to the inside of the lower end of the movable sleeve 16, and damping is arranged between the inside of the movable sleeve 16 and the mounting sleeve 13; the top of the ball joint 4 is provided with a power socket 18, the power socket 18 is inserted with a power connector 19, and the power connector 19 is connected with the cabin power supply system through an explosion-proof cable.

[0033] In the process of adjusting the lighting structure, the user drives the ball joint 4 to rotate in the clamping block 3 by the movable sleeve 16 installed inside the mounting sleeve 13, thereby adjusting the angle of orientation, and the light emitted by the LED lamp bead 14 will be emitted through the lens 17, so by adjusting the position of the movable sleeve 16 inside the mounting sleeve 13, the distance between the lens 17 and the LED lamp bead 14 is adjusted, thereby adjusting the illumination range of the LED lamp bead 14.

[0034] In the description of the utility model, it is to explain that, unless there is definite stipulation and limitation, the term "link" "connection" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through intermediate medium.
