[0019] Below in conjunction with specific embodiment, the technical scheme of the present invention is further described:
[0020] A marine cabin lighting equipment, such as Figure 1-2 As shown, it includes a fixed base 1, a movable base 2, an installation base, and a lighting device. The lower end of the fixed base 1 is a tubular structure, and a steel pipe can be directly selected. The upper end of the movable base 2 is cylindrical, and the upper end of the fixed base 1 is in the shape of a cylinder. It is welded and fixed on the cabin reverse roof 3, and the upper end of the movable base 2 is inserted into the fixed base 1 from the lower end of the fixed base 1; The lower end is vertically fixed in the middle of the beam 4, and the two ends of the beam 4 are respectively provided with a suspension device 5; The hanging ears at both ends of the light tube 6 are respectively suspended on the suspension devices 5 at both ends of the beam 4, and then the lighting device is installed on the lower end of the mounting base; the outer side of the fixed base 1 is also provided with a reinforcing support 8, and one end of the reinforcing support 8 is connected to the cabin. The reverse top 3 is welded and fixed, and the other end of the reinforcing support 8 is welded and fixed with the outer side of the fixed base 1, which plays a role of structural strengthening.
[0021] In order to realize the up and down adjustment of the movable base 2 relative to the fixed base 1, a limit device is also provided between the fixed base 1 and the movable base 2, and the limit device includes a limit hole 9, an adjustment hole 10, and a limit pin 11. , wherein the limit holes 9 are arranged on the outer side of the lower end of the fixed base 1, and the limit holes 9 are distributed along the outer side of the lower end of the fixed base 1 in a circle. The outer side of the base is evenly distributed in a ring shape; the adjustment holes 10 are arranged on the outer side of the upper end of the movable base 2, and the adjustment holes 10 are distributed in several layers up and down along the outer length direction of the movable base 2, and the adjustment holes 10 of each layer are along the outer side of the movable base. In this embodiment, each layer 4 and the adjustment holes are evenly distributed; adjust the length of the movable base 2 inserted into the fixed base 1, the adjustment holes on one layer are aligned with the limit holes, and the limit pins 11 are inserted into the adjustment holes 10 and the limit hole 9, and fix its position; if the angle needs to be adjusted, rotate the movable base 2 relative to the fixed base 1, and also align the adjustment hole and limit hole, and insert the limit pin 11 into the adjustment hole 10 and limit hole 9 for fixing.
[0022] Another implementation, such as image 3 As shown, on the basis of the previous embodiment, in order to prevent the movable base 2 from being separated from the fixed base 1 when the limit pin 11 is pulled out for adjustment, an anti-falling block 12 is also provided at the lower end of the fixed base 1 to prevent falling. The stopper 12 is a ring-shaped steel plate, which is fixed to the lower end of the fixed base 1 by screws or welding. The clearance of the movable base 2 passes through the anti-falling stopper 12. The upper end of the movable base is provided with a limit block 13. The limit block 13 The outside is circular, the outer diameter of the stop block 13 is larger than the inner ring diameter of the anti-fall stop block 12, and the outer diameter of the stop block 13 is smaller than the tubular inner diameter of the fixed base 1. Once the movable base 2 falls relative to the fixed base 1 , the limit block 13 is blocked by the anti-falling block 12; in order to prevent the strip lamp 6 from being damaged when the movable base 2 falls relative to the fixed base 1, a buffer spring 14 is also provided at the lower end of the limit block 13. The buffer spring 14 is sleeved on the outer side of the upper end of the movable base 2, and one end of the buffer spring 14 is clamped and fixed with the limit block 13, which can play a buffering role when it falls.
[0023] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. Those skilled in the art can make non-creative modifications to this embodiment as required after reading this specification, but only within the scope of the claims of the present invention are protected by patent law.
