DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A ceiling lamp that is easy to maintain, such as Figure 1-Figure 7 As shown, it includes a bottom shell 1, a transparent plate 2, a lighting lamp 3, an electrical connector 31, a top shell 4, a cross mounting frame 5, a mounting bolt 6, an electrical connector 7, a control lifting mechanism and a connecting structure. The bottom of the bottom shell 1 is connected to the transparent plate 2, the lighting lamp 3 is placed in the bottom shell 1, and the middle of the top of the lighting lamp 3 is provided with an electrical connector 31. The top of the top shell 4 is connected to the cross mounting frame 5, and the four ends of the cross mounting frame 5 are rotatably connected to the mounting bolts 6. The mounting bolts 6 can be rotated to screw the mounting bolts 6 into the room. Roof, thereby fixing the top shell 4 indoors, a power connector 7 is installed in the middle of the top shell 4, and the indoor circuit can be electrically connected to the power connector 7. When the bottom shell 1 and the top shell 4 are spliced ​​together, the power connector 7 and the power connector 31 are connected, and then the lighting lamp 3 can be controlled by controlling the indoor circuit switch. A control lifting mechanism is provided on the top shell 4, and a connecting structure is provided on the bottom shell 1. The control lifting mechanism is connected to the connecting structure, so that the control lifting mechanism can drive the bottom shell 1 to move upward through the connecting structure.

[0031] like Figure 2-Figure 4 As shown, the control lifting mechanism includes a swivel 81, a large bevel gear 82, a winding wheel 83, a transmission bevel gear 84, a connecting rope 85 and a driving structure. The bottom of the top shell 4 is connected to the swivel 81, and the large bevel gear 82 is rotatably connected to the swivel 81. The bottom of the top shell 4 is rotatably connected to four winding wheels 83 at uniform intervals along the circumferential direction. Each winding wheel 83 is connected to a transmission bevel gear 84, and the transmission bevel gear 84 is meshed with the large bevel gear 82 so that the large bevel gear 82 can drive the transmission bevel gear 84 to rotate when it rotates. A connecting rope 85 is wound around the winding wheel 83, and the end of the connecting rope 85 is mutually engaged with the connecting structure. The top shell 4 is provided with a driving structure, and the driving structure is used to drive the large bevel gear 82 to rotate.

[0032] like Figure 4 As shown, the driving structure includes a driving motor 86 and a driving bevel gear 87. The driving motor 86 is installed on the right side of the bottom of the top shell 4. The driving bevel gear 87 is connected to the output shaft of the driving motor 86. The driving bevel gear 87 is meshed with the large bevel gear 82 so that the driving bevel gear 87 can drive the large bevel gear 82 to rotate when it rotates.

[0033] like Figure 5As shown, the connection structure includes a connecting ring 91, a locking sleeve 92 and a locking ball 93. The connecting ring 91 is installed in the bottom shell 1. Four locking sleeves 92 are evenly spaced along the circumferential direction on the top of the connecting ring 91. The ends of the four connecting ropes 85 are connected to locking balls 93. The locking balls 93 can be inserted into the four locking sleeves 92, so that the connecting ropes 85 are engaged with the locking sleeves 92. At this time, the connecting ropes 85 are retracted to drive the connecting ring 91 and the bottom shell 1 to move upward, so that the bottom shell 1 is connected to the top shell 4.

[0034] When the ceiling lamp is needed, the present ceiling lamp can be used. When in use, the present ceiling lamp is installed on the indoor roof by installing the bolts 6, and then the power connector 7 is electrically connected to the indoor circuit. After the connection is completed, the driving motor 86 is controlled to drive the driving bevel gear 87 to rotate. When the driving bevel gear 87 rotates, it can drive the large bevel gear 82 to rotate. When the large bevel gear 82 rotates, it can drive the winding wheel 83 to rotate through the transmission bevel gear 84. When the winding wheel 83 rotates, it can retract the connecting rope 85, thereby pulling the bottom shell 1 upward through the locking sleeve 92 and the connecting ring 91, so that the bottom shell 1 and the top shell 4 are spliced ​​together. At this time, the power connector 31 is also connected to the power connector 7, and then the present ceiling lamp can be used. When maintenance is needed, it is only necessary to control the driving motor 86 to drive the driving bevel gear 87 to rotate in the opposite direction, so that the winding wheel 83 can rotate in the opposite direction to lower the connecting rope 85 through the transmission of the large bevel gear 82 and the transmission bevel gear 84, which can drive the bottom shell 1 to descend. At this time, it is convenient to inspect the lighting lamp 3 inside the bottom shell 1. If the bottom shell 1 needs to be taken out and moved to another position for inspection, the locking ball 93 can be pulled out of the locking sleeve 92, and then the bottom shell 1 can be taken out. When installation is needed, the locking ball 93 can be inserted into the locking sleeve 92. In this way, the ceiling lamp can be used, and after a failure occurs during use, the internal lighting lamp 3 can be inspected and repaired more conveniently.

[0035] like Figure 8 As shown, a locking mechanism is also included, which includes a wedge block 101 and an elastic member 102. Four wedge blocks 101 are slidably connected to the top of the connecting ring 91 at uniform intervals along the circumferential direction. The wedge blocks 101 can be stuck on the lighting lamp 3, so as to fix the lighting lamp 3 in the middle position of the bottom shell 1. An elastic member 102 is connected between the wedge block 101 and the connecting ring 91, and the elastic member 102 is a return spring.

[0036] When placing the lamp 3, directly put the lamp 3 into the bottom shell 1 from top to bottom. During the process of putting the lamp 3, the lamp 3 will squeeze the four wedge blocks 101 away from each other, and the elastic member 102 will be compressed until the lamp 3 moves to no longer resist the wedge blocks 101. Under the action of the elastic member 102, the wedge blocks 101 are reset to clamp the lamp 3, thereby locking the lamp 3 in the bottom shell 1. In this way, the lamp 3 can be fixed in the middle of the bottom shell 1 to avoid position deviation of the lamp 3. When the lamp 3 needs to be removed, the four wedge blocks 101 can be directly pulled away from the lamp 3.

[0037] like Figure 9-11 As shown, it also includes a synchronous adjustment mechanism, which includes a guide sleeve 103, a piston rod 104, a connecting pipe 105, a circulation pipe 108, a cylinder body 106 and a piston rod 107. Four guide sleeves 103 are evenly spaced along the circumferential direction at the bottom of the connecting ring 91. The four guide sleeves 103 are respectively close to four wedge blocks 101. A piston rod 104 is slidably connected in each guide sleeve 103. The piston rod 104 is connected to the wedge block 101. A connecting pipe 105 is connected between the four guide sleeves 103. A cylinder body 106 is installed on the right side of the bottom of the ring 91, and a piston rod 107 is slidably connected inside the cylinder body 106. A flow pipe 108 is connected between the cylinder body 106 and the connecting pipe 105. The cylinder body 106, the flow pipe 108, the connecting pipe 105 and the guide sleeve 103 are all filled with liquid. When the piston rod 107 is squeezed to move, the piston rod 107 can squeeze the liquid in the cylinder body 106 and inject the liquid in the cylinder body 106 into the guide sleeve 103 through the connecting pipe 105, so that the guide sleeve 103 drives the wedge block 101 to move.

[0038] When the four wedge blocks 101 need to be operated to move away from each other, the piston rod 107 can be pulled upward. When the piston rod 107 moves upward, the liquid in the guide sleeve 103 can be extracted through the circulation tube 108 and the connecting tube 105, so that the piston rod 104 can be retracted into the guide sleeve 103. When the piston rod 104 moves, it can drive the wedge block 101 to move, so that the wedge block 101 is separated from the lighting lamp 3. In this way, the four wedge blocks 101 can be operated to separate from the lighting lamp 3 at the same time without manual operation one by one, which is more convenient during operation.

[0039] like Fig.12As shown, a heat dissipation mechanism is also included, and the heat dissipation mechanism includes heat-conducting fins 111 and a heat dissipation ring 112. A plurality of heat-conducting fins 111 are evenly spaced along the circumferential direction at the lower part of the bottom shell 1, and the heat dissipation ring 112 is connected between the outer sides of the plurality of heat-conducting fins 111. The heat-conducting fins 111 can absorb the heat inside the bottom shell 1 and conduct the heat to the heat dissipation ring 112. The heat dissipation is processed by the heat dissipation ring 112, so as to achieve the effect of cooling the inside of the bottom shell 1.

[0040] like Fig.13 As shown, it also includes a guide bevel 12. A plurality of guide bevels 12 are evenly spaced along the circumferential direction at the bottom of the top shell 4. When the bottom shell 1 moves upward, the bottom shell 1 will contact the outer side of the guide bevel 12. At this time, the guide bevel 12 can guide the movement of the bottom shell 1, so that the bottom shell 1 and the top shell 4 can be better spliced ​​together.
