[0027] ​​​Aluminum alloy is the most widely used non-ferrous structural material in industry, which has been widely used in aviation, automobile, machinery manufacturing, shipbuilding and chemical industry. Among them, the aluminum alloy lamp holder as the equipment for fixing the lamp has the advantage of light weight. However, when most of the lamp holder main body and the fixed plate for installing the lamp are assembled, the bolt, buckle and other ways are usually used for fixing, and the firmness of most of the lamp holder is not strong enough. In this way, when the lamp is installed on the lamp holder, due to the weight of the lamp itself, the lamp holder is prone to looseness, uneven stress and other adverse phenomena after a long time.

[0028] In view of this, the embodiment provides an aluminum alloy lamp holder, which has the advantages of firm structure and balanced stress.

[0029] Please refer to Figures 1 to 6 , the embodiment provides an aluminum alloy lamp holder, which comprises a lamp holder main body 10, a fixed plate 20 and a connecting sleeve 30. The four corners of the end face of the lamp holder main body 10 are respectively provided with open pipe barrels 12. The four corners of the fixed plate 20 are respectively provided with sleeve rings 21. The connecting sleeve 30 is a tubular structure with open ends. The outer circumferential side of the connecting sleeve 30 extends radially outward to form a connecting welding ring 31. One end of the connecting sleeve 30 is inserted into the pipe barrel 12, and one end of the connecting welding ring 31 abuts at the opening edge of the pipe barrel 12. A first welding seam ring is welded at the connection between the connecting welding ring 31 and the pipe barrel 12. The sleeve ring 21 is sleeved on the outer circumferential side of the connecting sleeve 30, and one end of the sleeve ring 21 abuts away from the pipe barrel 12. A second welding seam ring is welded at the connection between the sleeve ring 21 and the connecting welding ring 31.

[0030] Specifically, in the embodiment, the outer diameter of the sleeve ring 21 is equal to the outer diameter of the connecting welding ring 31, and the inner diameter of the sleeve ring 21 is slightly larger than the outer diameter of the connecting sleeve 30. The outer diameter of the pipe barrel 12 is equal to the outer diameter of the connecting welding ring 31, and the inner diameter of the pipe barrel 12 is slightly larger than the outer diameter of the connecting sleeve 30. In addition, the axial length of the sleeve ring 21 of the embodiment is equal to the axial distance from the end of the connecting sleeve 30 away from the pipe barrel 12 to the connecting welding ring 31. It can be understood that one end of the connecting sleeve 30 is inserted into the pipe barrel 12 until the connecting welding ring 31 of the connecting sleeve 30 abuts on the port edge of the pipe barrel 12. In this way, the connection between the connecting welding ring 31 and the pipe barrel 12 can be fixedly connected by welding, thereby generating a first welding seam ring. Then, the sleeve ring 21 on the fixed plate 20 is inserted into the other end of the connecting sleeve 30 and abuts on the connecting welding ring 31. In this way, the connection between the connecting welding ring 31 and the sleeve ring 21 can be fixedly connected by welding, thereby generating a second welding seam ring. In addition, the port of the connecting sleeve 30 is flush with the port of the sleeve ring 21 and does not exceed the outside of the sleeve ring 21.

[0031] In addition, in the embodiment, the four corners of the two end faces of the lamp holder body 10 are provided with open pipe barrels 12, and the number of the fixing plates 20 is two. The lamp holder body 10 comprises four parallel and spaced long pipes 11, and a connecting pipe 13 is arranged between the two adjacent long pipes 11. The four long pipes 11 and the connecting pipe 13 jointly constitute the lamp holder body 10, and the two ends of the long pipe 11 are provided with open pipe barrels 12. The connecting pipe 13 is arranged obliquely between the two adjacent long pipes 11.

[0032] Further, the middle part of the fixing plate 20 of the embodiment is provided with a first through hole 22. A plurality of second through holes 23 are provided on the fixing plate 20, the plurality of second through holes 23 are located on the same circumference, and the plurality of second through holes 23 are distributed around the first through hole 22. The diameter of the second through hole 23 is smaller than the diameter of the first through hole 22. It can be understood that the first through hole 22 or the second through hole 23 can be used as the assembly hole between the aluminum alloy lamp holder and the lamp.

[0033] In the embodiment, the lamp holder body 10, the fixing plate 20 and the connecting sleeve 30 can be made of aluminum alloy.

[0034] Compared with the prior art, the aluminum alloy lamp holder of the utility model, the four corners of the two end faces of the lamp holder body 10 are provided with pipe barrels 12, and the four corners of the two fixing plates 20 are correspondingly provided with four sleeve rings 21. In this way, the connecting sleeve 30 is inserted into each pipe barrel 12, and one end of the connecting welding ring 31 on the outer side wall of the connecting sleeve 30 abuts at the port of the pipe barrel 12. In this way, a first welding seam ring can be welded at the connecting position of the connecting welding ring 31 and the pipe barrel 12, so that the connection between the connecting welding ring 31 and the pipe barrel 12 is tight and firm. Further, the fixing plate 20 is sleeved on the connecting sleeve 30 in the four pipe barrels 12 through the four corner sleeve rings 21 respectively, and the sleeve ring 21 abuts at the other end of the connecting welding ring 31. In this way, a second welding seam ring can be welded at the connecting position of the connecting welding ring 31 and the sleeve ring 21, so that the connection between the sleeve ring 21 and the connecting welding ring 31 is more tight and firm. In addition, the fixing plate 20 and the lamp holder body 10 of the utility model are assembled and connected through the four connecting sleeves 30. The connection between the three can be quickly and conveniently realized, and the combination between the three is more tight and firm through the matched welding between the connecting sleeve 30 and the pipe barrel 12 and the sleeve ring 21. At the same time, the stress of the aluminum alloy lamp holder is more balanced through the matched fixing of the four sleeves and the four sleeve rings 21, and deformation is not easy to occur. In this way, when the aluminum alloy lamp holder of the utility model is assembled with stage equipment, lamps and lanterns and the like, the firmness is sufficient to overcome the weight of the lamps and lanterns, and the service life of the aluminum alloy lamp holder is effectively improved.

[0035] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
