[0005] Preferably: the motor is connected to an external PLC controller via a signal transmission line.

[0006] Further: the transmission mechanism includes a first gear, a rotating shaft, a third gear and a transmission belt. The rotating shaft is rotatably connected to an outer wall of one side of the side baffle. The first gear is fixed to the outer wall of the active rod. The third gear is fixed to the outer wall of the rotating shaft. The first gear and the third gear are meshed and connected. The transmission belt is transmission-connected to the outer wall of the rotating shaft and the driven rod.

[0011] On the basis of the above-mentioned solution: an inclined plate is fixed on the outer wall of the top of the lamp body, and a pulley is rotatably connected to the outer wall of the inclined plate.

[0012] Based on the above solution, preferably: an outer wall of one side of the side baffle is provided with a breathable filter screen, a lampshade is fixed to the outer wall of the lamp body, and a trumpet-shaped buffer sleeve is provided on the inner wall of the installation groove.

[0013] A process for installing a banquet ceiling lamp comprises the following steps: S1: The staff fixes one end of the traction rope of corresponding length to the inner wall of the winding drum, and then fixes the other end of the traction rope to the lifting ring; S2: The staff controls the motor through the PLC controller to drive the active rod to rotate the corresponding number of circles, and pulls the lamp body upward through the traction rope; S3: When the lamp body as a whole is moved into the installation slot under the traction of the traction rope, the PLC controller controls the motor to stop running, completing the installation of the lamp body.

[0014] The beneficial effects of the present invention are: 1. The present invention can automatically drive a row of lamp bodies installed inside the ceiling body to move up and down a corresponding distance under the drive of a motor without the need for workers to climb up, so that it is convenient for workers to replace and maintain the lamp bodies. At the same time, the lamp bodies that move up and down following the rotation of the motor can complete automatic breakpoint and power-on work through the first conductive thimble and the second conductive thimble, so that the lamp bodies are automatically powered off when moving downward, and are automatically powered on when moving upward back to the inside of the ceiling body, thereby improving the convenience of lamp installation.

[0015] 2. The PLC controller controls the motor to drive the active rod to rotate clockwise, thereby releasing the traction rope wound inside the winding drum. When the active rod rotates, it can drive the driven rod to rotate relatively through the transmission mechanism, so that the winding drums arranged on the outer walls of the active rod and the driven rod can release the traction rope at the same time. When the active rod and the driven rod rotate relatively, the pushing mechanism of the outer wall will be driven to operate at the same time, thereby pushing the lamp body stuck in the installation groove downward, pushing the lamp body out of the installation groove, allowing the lamp body to continue to move downward under the traction of the continuously released traction rope, so that a row of lamp bodies installed inside the ceiling body can be moved downward to the side of the staff under the traction of multiple traction ropes, and the staff can replace and maintain the lowered lamp body without climbing high.

[0016] 3. When the motor drives the active rod to rotate, the active rod can drive the third gear to rotate through the first gear on the outer wall, thereby driving the rotating shaft and the active rod to rotate in the opposite direction through the third gear. When the rotating shaft rotates, the transmission belt on the outer wall will drive the driven rod to rotate in the same direction as the rotating shaft, so that the active rod can drive the driven rod to rotate in the opposite direction when rotating, so that the winding drums on the outer walls of the active rod and the driven rod can release and reel in the wire together, and the lamp body can be stably pulled up and down by the traction rope.

[0017] 4. When the motor drives the active rod to rotate clockwise and release the traction rope downward through the winding drum, the second gear located on the outer wall of the active rod and the driven rod will also rotate with the active rod and the driven rod, thereby pushing the rack plate meshing with it to move downward, pushing out the lamp body stuck in the installation groove, so that the lamp body can be smoothly moved out of the installation groove when the winding drum releases the line.

[0018] 5. When the lamp body moves into the installation groove under the traction of the traction rope, the limit plate located on the inner wall of the ceiling body can limit and block the lamp body. At the same time, a group of guide blocks located on the top of the lamp body will also be inserted into the rectangular socket on the limit plate. As the guide block continues to move upward, the arc-shaped spring piece will continue to shrink under the squeeze of the inner wall of the rectangular socket. When the arc-shaped spring piece as a whole moves out of the outer wall of the rectangular socket driven by the guide block, the arc-shaped spring piece will bounce up again under the drive of its own elastic force and the elastic force of the conical airbag, thereby resting on one side of the block, supporting and limiting the lamp body moved to the inner wall of the installation groove, and improving the supporting and fixing effect of the ceiling body on the lamp body.

[0027] Embodiment 1: A banquet ceiling lamp, such as Figure 1-7As shown, it includes a ceiling body 1, wherein the bottom outer wall of the ceiling body 1 is provided with a plurality of mounting grooves 33, a fixing plate 9 is fixed to the top inner wall of the ceiling body 1, a junction box 27 is fixed to the bottom outer wall of the fixing plate 9, a first conductive ejector pin 24 is connected to the bottom outer wall of the junction box 27 through a power transmission line, and conductive joints 28 are respectively arranged on the outer walls of both sides of the junction box 27, a side baffle 2 is fixed to the outer wall of one side of the ceiling body 1, an active rod 12 and a driven rod 13 are rotatably connected to the inner wall of the side baffle 2, a winding roller 17 is respectively fixed to the outer walls of the active rod 12 and the driven rod 13, and the inner wall of the winding roller 17 The wall is connected to a lifting ring 20 through a traction rope, a lamp body 5 is fixed on the outer wall of the lifting ring 20, the lamp body 5 is inserted into the inner wall of the mounting groove 33, a second conductive ejector pin 36 is fixed to the outer wall at the top of the lamp body 5, a motor 3 is fixed to the outer wall on one side of the side baffle 2, the output shaft of the motor 3 passes through the outer wall on one side of the side baffle 2, the output shaft of the motor 3 is connected to the outer wall on one side of the active rod 12 through a coupling, a transmission mechanism is provided on the outer wall on one side of the side baffle 2, and a pushing mechanism is provided on the outer walls of the lamp body 5, the active rod 12 and the driven rod 13; the motor 3 is connected to an external PLC controller through a signal transmission line.

[0028] When the staff needs to replace and maintain the lamp body 5 installed inside the ceiling body 1, firstly, the PLC controller controls the motor 3 to drive the active rod 12 to rotate clockwise, so that the traction rope wound inside the winding drum 17 is released outward. When the active rod 12 rotates, it can drive the driven rod 13 to rotate relatively together through the transmission mechanism, so that the winding drum 17 arranged on the outer wall of the active rod 12 and the driven rod 13 simultaneously releases the traction rope outward. When the active rod 12 and the driven rod 13 rotate relatively, the pushing mechanism of the outer wall is driven to operate at the same time, so as to push the lamp body 5 stuck inside the installation groove 33 downward, and push the lamp body 5 out of the installation groove 33, so that the lamp body 5 is continuously moved downward under the traction of the continuously released traction rope. The staff can connect the traction rope of corresponding length between the hanging ring 20 and the winding drum 17 according to the actual height of the ceiling body 1, so that a row of lamp bodies 5 installed inside the ceiling body 1 can be moved downward to the side of the staff under the traction of multiple traction ropes, and the staff can replace and maintain the lowered lamp body 5 without climbing up. After the lamp body 5 is replaced and maintained, the motor 3 can be controlled by the PLC controller to drive the active rod 12 to rotate in the opposite direction, thereby driving the winding drum 17 to wind up the traction rope, and the lamp body 5 after maintenance and replacement is pulled upward at a uniform speed. When the lamp body 5 as a whole moves to the inside of the installation groove 33 driven by the traction rope, the second conductive ejector pin 36 arranged on the outer wall of the top of the lamp body 5 will abut against the bottom of the first conductive ejector pin 24, so that the lamp body 5 is electrically connected to the junction box 27 through the second conductive ejector pin 36, the first conductive ejector pin 24 and the power transmission line arranged inside the corrugated sleeve 25, so that the lamp body 5 is pulled to the installation groove 33 by the traction rope. The lamp body 5 inside the mounting groove 33 can be automatically connected to electricity, so that the staff can automatically drive a row of lamp bodies 5 installed inside the ceiling body 1 to move up and down a corresponding distance under the drive of the motor 3 without the need for climbing, which is convenient for the staff to replace and maintain the lamp body 5. At the same time, the lamp body 5 that moves up and down following the rotation of the motor 3 can complete automatic breakpoint and power connection through the first conductive ejector pin 24 and the second conductive ejector pin 36, so that the lamp body 5 is automatically powered off when moving downward, and the lamp body 5 that moves upward back to the inside of the ceiling body 1 is automatically powered on, which improves the convenience of installing the lamp body 5.

[0029] like Figure 2-3 As shown, the transmission mechanism includes a first gear 8, a rotating shaft 19, a third gear 18 and a transmission belt 7. The rotating shaft 19 is rotatably connected to an outer wall of one side of the side baffle 2. The first gear 8 is fixed to the outer wall of the active rod 12, and the third gear 18 is fixed to the outer wall of the rotating shaft 19. The first gear 8 is meshed and connected with the third gear 18, and the transmission belt 7 is transmission-connected to the outer wall of the rotating shaft 19 and the driven rod 13. When the motor 3 drives the active rod 12 to rotate, the active rod 12 can drive the third gear 18 to rotate through the first gear 8 on the outer wall, thereby driving the rotating shaft 19 and the active rod 12 to rotate in the opposite direction through the third gear 18. When the rotating shaft 19 rotates, the driven rod 13 and the rotating shaft 19 are driven to rotate in the same direction through the transmission belt 7 on the outer wall, so that the active rod 12 can drive the driven rod 13 to rotate in the opposite direction when rotating, so that the winding drum 17 on the outer wall of the active rod 12 and the driven rod 13 can release and reel in the wire together, and the lamp body 5 is stably pulled up and down by the traction rope.

[0030] like Figure 4As shown, the pushing mechanism includes a second gear 11, a rack plate 15 and a suction cup 21, the second gear 11 is fixed on the outer walls of the active rod 12 and the driven rod 13 respectively, the rack plate 15 is fixed on the top outer wall of the lamp body 5, the second gear 11 is meshedly connected with the rack plate 15, and the suction cup 21 is fixed on the top outer wall of the rack plate 15; when the motor 3 drives the active rod 12 to rotate clockwise through the winding drum 17 to release the traction rope downward, the second gear 11 located on the outer wall of the active rod 12 and the driven rod 13 will also rotate with the active rod 12 and the driven rod 13, thereby pushing the meshed rack plate 15 to move downward, and ejecting the lamp body 5 stuck in the mounting groove 33, so that the lamp body 5 can be wound on the winding drum 17. When laying out the wire, it is smoothly moved out of the installation groove 33. When the lamp body 5 moves upward to the inner wall of the installation groove 33 under the traction of the traction rope, the lamp body 5 as a whole will move to the corresponding position inside the installation groove 33 under the limit of the traction rope and the installation groove 33, so that a set of rack plates 15 on the top of the lamp body 5 can be re-engaged with the rotating second gear 11. When the PLC controls the motor 3 to rotate a corresponding number of circles, the lamp body 5 as a whole will move upward to the inside of the installation groove 33. At this time, a set of rack plates 15 on the top of the lamp body 5 will be engaged and connected to one side of the second gear 11. At the same time, the suction cup 21 located on the top of the rack plate 15 will rest on the top inner wall of the ceiling body 1, so as to support and cushion the lamp body 5 as a whole that rises to the inner wall of the installation groove 33.

[0031] like Figure 5 As shown, a group of elastic telescopic rods 26 are fixed to the outer wall of the fixing plate 9, and a mounting plate 29 is fixed to the telescopic end of the elastic telescopic rods 26. The outer wall of the bottom of the mounting plate 29 is arranged on the outer wall of the first conductive thimble 24; when the second conductive thimble 36 is pulled against the bottom of the first conductive thimble 24 by the traction of the traction rope, the elastic telescopic rod 26 located on the top outer wall of the mounting plate 29 will buffer the first conductive thimble 24 to avoid a hard collision between the second conductive thimble 36 and the first conductive thimble 24 when rising. At the same time, the elastic telescopic rod 26 can push the first conductive thimble 24 and the second conductive thimble 36 together through its own elastic force, thereby improving the stability of the electrical connection between the lamp body 5 and the junction box 27.

[0032] like Figure 4-7As shown, a guide block 22 is fixed to the outer wall of the top of the lamp body 5, a conical air bag 30 is fixed to the outer wall of the guide block 22, an arc-shaped spring piece 23 is fixed to the outer wall of the conical air bag 30, and sliders 31 are fixed to the outer walls on both sides of the arc-shaped spring piece 23, and the sliders 31 are slidably connected to the inner wall of the guide block 22; a group of limiting plates 16 are fixed to the inner wall of the bottom of the ceiling body 1, and a rectangular plug hole 32 is opened on the outer wall of the limiting plate 16, and a stopper 34 is fixed to the inner wall of the rectangular plug hole 32, and the guide block 22 is slidably connected to the inner wall of the rectangular plug hole 32; when the lamp body 5 moves to the inside of the installation groove 33 under the traction of the traction rope, the limiting plate 16 located on the inner wall of the ceiling body 1 can limit and block the lamp body 5, and at the same time, a group of guide blocks 22 located on the top of the lamp body 5 will also be inserted into the limiting plate 16. In the rectangular socket 32 ​​on the positioning plate 16, as the guide block 22 continues to move upward, the arc-shaped spring piece 23 will continue to shrink under the pressure of the inner wall of the rectangular socket 32. When the arc-shaped spring piece 23 as a whole moves out of the outer wall of the rectangular socket 32 ​​driven by the guide block 22, the arc-shaped spring piece 23 will bounce up again under the drive of its own elastic force and the elastic force of the conical air bag 30, thereby abutting against one side of the stop block 34, supporting and limiting the lamp body 5 moved to the inner wall of the mounting groove 33, thereby improving the supporting and fixing effect of the ceiling body 1 on the lamp body 5. At the same time, when the pushing mechanism pushes the lamp body 5 downward to move out of the mounting groove 33, the arc-shaped spring piece 23 and the conical air bag 30 as a whole can also shrink under the pressure of the stop block 34, thereby allowing the guide block 22 to move downward and out of the rectangular socket 32.

[0033] like Figure 5 As shown, an inclined plate 14 is fixed to the outer wall of the top of the lamp body 5, and the outer wall of the inclined plate 14 is rotatably connected to a pulley 10; when the lamp body 5 as a whole rises to the bottom of the mounting groove 33 driven by the traction rope, the pulley 10 located at the top of the inclined plate 14 will first contact the inner wall of the mounting groove 33, thereby supporting and limiting the lamp body 5 moved to the bottom of the mounting groove 33. Since the banquet hall is usually a relatively sealed space, there is usually no large airflow inside, so the lamp body 5 as a whole will not produce a large shake during the rising process. Therefore, when the inclined plate 14 is inserted into the mounting groove 33 with the pulley 10 against it, the friction between the pulley 10 and the inner wall of the mounting groove 33 can make the lamp body 5 that produces a slight shake during the rise stabilize, so that the guide block 22, the rack plate 15 and the second conductive ejector pin 36 can be accurately moved to the corresponding positions inside the ceiling body 1.

[0034] like Figure 4-7As shown, a breathable filter 6 is provided on the outer wall of one side of the side baffle plate 2, a lampshade 4 is fixed on the outer wall of the lamp body 5, and a trumpet-shaped buffer sleeve 35 is provided on the inner wall of the mounting groove 33; the trumpet-shaped buffer sleeve 35 can limit the support of the lamp body 5 inserted into the mounting groove 33 through its own elastic force, and at the same time, the lampshade 4 on the outer wall of the lamp body 5 can be blocked on the outer wall of the mounting groove 33 to cover the gap between the lamp body 5 and the mounting groove 33, thereby improving the overall aesthetics of the lamp body 5. At the same time, the heat generated by the operation of the lamp body 5 can be discharged outward through the breathable filter 6 on one side of the side baffle plate 2.

[0035] When the present embodiment is in use, when the staff needs to replace and maintain the lamp body 5 installed inside the ceiling body 1, firstly, the PLC controller is used to control the motor 3 to drive the active rod 12 to rotate clockwise, so that the traction rope wound inside the winding drum 17 is released outwardly. When the active rod 12 rotates, the driven rod 13 can be driven to rotate relatively together through the transmission mechanism, so that the winding drum 17 arranged on the outer wall of the active rod 12 and the driven rod 13 simultaneously releases the traction rope outwardly. When the active rod 12 and the driven rod 13 rotate relatively, the pushing mechanism of the outer wall is driven to operate at the same time, and the lamp body 5 stuck inside the installation groove 33 is pushed downward, and the lamp body 5 is pushed out of the installation groove 33, so that the lamp body 5 is continuously moved downward under the traction of the continuously released traction rope. The staff can connect the traction rope of corresponding length between the hanging ring 20 and the winding drum 17 according to the actual height of the ceiling body 1, so that a row of lamp bodies 5 installed inside the ceiling body 1 can be moved downward to the side of the staff under the traction of multiple traction ropes, and the staff can replace and maintain the lowered lamp body 5 without climbing.

[0036] After the lamp body 5 is replaced and maintained, the motor 3 can be controlled by the PLC controller to drive the active rod 12 to rotate in the opposite direction, thereby driving the winding drum 17 to wind up the traction rope, and the lamp body 5 after maintenance and replacement is pulled upward at a uniform speed. When the lamp body 5 as a whole moves to the inside of the installation groove 33 driven by the traction rope, the second conductive ejector pin 36 arranged on the outer wall of the top of the lamp body 5 will abut against the bottom of the first conductive ejector pin 24, so that the lamp body 5 is electrically connected to the junction box 27 through the second conductive ejector pin 36, the first conductive ejector pin 24 and the power transmission line arranged inside the corrugated sleeve 25, so that the lamp body 5 can be electrically connected to the junction box 27 through the second conductive ejector pin 36, the first conductive ejector pin 24 and the power transmission line arranged inside the corrugated sleeve 25. The lamp body 5 pulled into the installation groove 33 by the traction rope can be automatically powered on, so that the staff can automatically drive a row of lamp bodies 5 installed inside the ceiling body 1 to move up and down a corresponding distance under the drive of the motor 3 without the need for climbing, which is convenient for the staff to replace and maintain the lamp body 5. At the same time, the lamp body 5 that moves up and down following the rotation of the motor 3 can complete automatic breakpoint and power connection through the first conductive ejector pin 24 and the second conductive ejector pin 36, so that the lamp body 5 is automatically powered off when moving downward, and the lamp body 5 that moves upward back to the inside of the ceiling body 1 is automatically powered on.

[0037] When the motor 3 drives the active rod 12 to rotate, the active rod 12 can drive the third gear 18 to rotate through the first gear 8 on the outer wall, thereby driving the rotating shaft 19 to rotate in the opposite direction of the active rod 12 through the third gear 18. When the rotating shaft 19 rotates, the driven rod 13 will be driven to rotate in the same direction as the rotating shaft 19 through the transmission belt 7 on the outer wall, so that the active rod 12 can drive the driven rod 13 to rotate in the opposite direction when rotating, so that the winding drum 17 on the outer wall of the active rod 12 and the driven rod 13 can release and reel in the wire together; when the motor 3 drives the active rod 12 to rotate clockwise through the winding drum 17 to release the traction rope downward, the second gear 11 located on the outer wall of the active rod 12 and the driven rod 13 will also rotate with the active rod 12 and the driven rod 13, thereby pushing the rack plate 15 meshing therewith to move downward, and ejecting the lamp body 5 stuck in the mounting groove 33, so that the lamp body 5 can be smoothly moved out of the mounting groove 33 when the winding drum 17 releases the wire.
