DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 to Figure 2 As shown, a preferred embodiment of the utility model provides a ship rocker-type lamp stand, including a column 1, a base 2 is installed at the bottom of the column 1, and the base 2 is fixed on the deck by bolts to ensure that the column 1 is perpendicular to the deck. In order to improve the stability of the column 1, a plurality of reinforcing plates 3 are connected between the side wall of the column 1 and the ship deck, and the utility model is preferably provided with four reinforcing plates 3.

[0023] A column 4 is fixedly mounted on the top of the column 1. The column 4 is cylindrical, and the axis of the column 4 is perpendicular to the deck. A shell 5 is mounted on the column 4. Specifically, a cavity 6 with an opening at the bottom is provided in the shell 5. The cavity 6 is also cylindrical and matches the column 4. The column 4 is located in the cavity 6, and the shell 5 and the column 4 are clearance-matched.

[0024] The column 4 and the shell 5 are rotatably connected by a rotating mechanism. Specifically, the rotating mechanism includes a ball 7, which can be a steel ball. A first spherical groove is provided in the middle of the top surface of the column 4, and a second spherical groove is provided on the top wall of the cavity 6. The second spherical groove is located directly above the first spherical groove. The ball 7 is placed in the first spherical groove and is in sliding contact with the first spherical groove and the second spherical groove respectively. The shell 5 can rotate 360 ​​degrees relative to the column 4 through the above arrangement.

[0025] The cavity 6 is filled with lubricating oil for lubricating the ball 7 to ensure that the ball 7 can rotate freely. A refueling port connected to the cavity 6 is provided on the top of the shell 5 for adding lubricating oil to the cavity 6. A detachable oil plug cap 8 is installed at the refueling port.

[0026] In addition, an annular groove is provided on the side wall of the column 4 , and a sealing ring 9 is provided in the annular groove. The sealing ring 9 is in close contact with the side wall of the cavity 6 to prevent the lubricating oil from leaking from the bottom of the cavity 6 .

[0027] The side wall of the housing 5 is provided with a threaded hole, in which a screw 10 is threadedly connected, a universal ball 11 is provided at one end of the screw 10 located inside the housing 5, and a hand wheel 12 is fixedly installed at one end of the screw 10 located outside the housing 5. By rotating the hand wheel 12, the universal ball 11 is pressed against the side wall of the column 4, thereby ensuring that the column 4 and the cavity 6 are coaxial.

[0028] The side wall of the housing 5 is fixedly connected with a crossbeam 13, and a rotatable floodlight 14 is installed at the end of the crossbeam 13. The side wall of the crossbeam 13 is provided with a handle 15. The handle 15 can be used to rotate the crossbeam 13 with the column 4 as the axis, thereby adjusting the position of the floodlight 14. When the sea surface needs to be illuminated, the crossbeam 13 can be rotated outward to rotate the floodlight 14 to the outside of the ship's side. When lighting is not required, the crossbeam 13 and the floodlight 14 can be rotated to the deck to meet the requirement that the floodlight 14 does not exceed the width of the ship. In addition, the relevant parts of the floodlight can be rotated to the deck, which is very convenient for maintenance.

[0029] Furthermore, a first connecting plate 16 is provided on the side wall of the housing 5, and a first through hole is provided on the first connecting plate 16. A plurality of second connecting plates 17 are provided on the side wall of the column 1 at equal intervals along the circumferential direction, and each second connecting plate 17 is provided with a second through hole. The first through hole and any second through hole can be overlapped by rotating the housing 5. The bolt 18 passes through the overlapping first through hole and second through hole in sequence and cooperates with the butterfly nut 19, the purpose of which is to lock the housing 5 and prevent the housing 5 from rotating by itself.

[0030] In addition, a grounding device 20 is provided on the side wall of the column 1 for grounding electrical equipment such as the floodlight 14 .

[0031] In summary, the ship swing arm lamp stand described in the embodiment of the utility model can rotate the floodlight to the outside of the ship's side when lighting is needed, and can rotate the floodlight to the deck when lighting is not needed, thereby meeting the requirement that the floodlight does not exceed the width of the ship. In addition, it is very convenient to repair the related parts of the floodlight.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
