[0034] Refer to Figures 1 to 4, this embodiment provides a lamp bracket connection structure for installing a lamp 6 to an external component; among them, the external component can be a wall, the inner wall of a tunnel, etc., or a component connected to a building such as a wall or the inner wall of a tunnel, or some other components, and specific restrictions are not made here.

[0035] Some of the threaded holes are the remaining part after a complete threaded hole is cut by a plane parallel to its axis. Preferably, some of the threaded holes are the remaining part after more than two-thirds of a complete threaded hole is cut by a plane parallel to its axis.

[0036] The lamp bracket connection structure includes a mounting base 1 and two connection components. The mounting base 1 is used to mount the lamp 6, and both ends of the mounting base 1 are respectively connected to the external component through the connection components. Preferably, the two connection components are symmetrically arranged at both ends of the mounting base 1; the mounting base 1 can be a heat dissipation structure such as a radiator or a heat dissipation plate of the lamp 6. In actual use, the lamp 6 is directly mounted on the heat dissipation structure, and then the heat dissipation structure is mounted to the external component through the two connection components.

[0037] The connection component includes a bracket 3 and a connecting plate 2. The bracket 3 is used to connect to the external component. The connecting plate 2 includes a first connecting portion 21 and a second connecting portion 22. The first connecting portion 21 is connected to the bracket 3 through a connecting bolt 4, and the second connecting portion 22 is connected to the mounting base 1 through a fastener 5. The fastener 5 can be a bolt or a screw, etc.

[0038] The first connecting portion 21 has an opposite first surface and a second surface. The first surface fits with the bracket 3 in the same connection component. Two first protruding members 211 are provided on the second surface. The two first protruding members 211 are arranged side by side at intervals. Partial threaded holes matching the connecting bolt 4 are provided on both of the two first protruding members 211. The partial threaded holes on the two first protruding members 211 face each other. In the same connection component, the connecting bolt 4 sequentially passes through the bracket 3 and the first connecting portion 21 and extends out from the second surface of the first connecting portion 21. The connecting bolt 4 is located between the two first protruding members 211 and the connecting bolt 4 is simultaneously threadedly connected to the partial threaded holes on the two first protruding members 211, thereby fixing the bracket 3 and the first connecting portion 21.

[0039] Compared with the prior art in which a protruding member capable of machining a threaded hole is provided on a structure similar to the connecting plate 2, the width of the first protruding member 211 of the present invention does not need to be greater than the diameter of the threaded hole, and the width of the first protruding member 211 can be set smaller, thereby reducing costs.

[0040] Further, the connecting plate 2 is bent at least once; preferably, it is bent twice in this embodiment. The two bends are the first bend and the second bend respectively. The connecting plate 2 further includes a shielding portion 23. The first connecting portion 21 is located between the first bend and the second bend. The first connecting portion 21 and the second connecting portion 22 are located on both sides of the first bend, and the first bend is that the second connecting portion 22 is bent relative to the first connecting portion 21 in the direction of the second surface among the first surface and the second surface. The first connecting portion 21 and the shielding portion 23 are located on both sides of the second bend, and the second bend is that the shielding portion 23 is bent relative to the first connecting portion 21 in the direction of the second surface among the first surface and the second surface.

[0041] Among the two first protruding members 211, one of the first protruding members 211 and the second connecting portion 22 are the same component, and the other first protruding member 211 is a specific first protruding member 211. The second connecting portion 22 has opposite third and fourth surfaces. The third surface faces the specific first protruding member 211, and part of the threaded holes on the second connecting portion 22 that match the connecting bolt 4 are provided on the third surface of the second connecting portion 22; the mounting seat 1 is connected to the fourth surface of the second connecting portion 22. In this way, one of the first protruding members 211 is replaced by the second connecting portion 22, which can save one first protruding member 211 and further reduce costs; and the second connecting portion 22 serves two purposes. More preferably, the first bend can be a 90° bend with an arc transition.

[0042] Two second protruding members 221 are provided on the third surface of the second connecting portion 22 and are arranged side by side at intervals. Part of the threaded holes that match the fastener 5 are provided on the two second protruding members 221 respectively. For the sake of distinction, the part of the threaded holes that match the connecting bolt 4 is called the first part of the threaded holes, and the part of the threaded holes that match the fastener 5 is called the second part of the threaded holes. The fastener 5 passes through the mounting seat 1 and the second connecting portion 22 in sequence and extends out from the third surface of the second connecting portion 22. The fastener 5 is located between the two second protruding members 221 and the fastener 5 is threadedly connected to the second part of the threaded holes on the two second protruding members 221 at the same time. Among them, the first part of the threaded holes on the third surface of the second connecting portion 22 extends to the two second protruding members 221; in this way, the first protruding member 221 is not only used for the connection of the fastener 5, but also can increase the threads for connecting with the connecting bolt 4, making the connection of the connecting bolt 4 firm and serving two purposes.

[0043] It should be noted that when setting the first protruding member 211, the second protruding member 221, the first partial threaded hole, the second partial threaded hole, etc., it is necessary to avoid interference between the components. For example, a certain gap needs to be left between the second protruding member 221 that is relatively closer to the first connecting portion 21 among the two second protruding members 221 on the second connecting portion 22 and the second surface of the first connecting portion 21.

[0044] The length of the first connecting portion 21 in the length direction of the first protruding member 211 is L1. The length of the first protruding member 211 can be less than L1, equal to L1, or greater than L1. Preferably, the length of the first protruding member 211 is equal to L1, that is, the first protruding member 211 is a rib protruding from the second surface of the first connecting portion 21. The length of the second connecting portion 22 in the length direction of the second protruding member 221 is L2. The length of the second protruding member 221 can be less than L2, equal to L2, or greater than L2. Preferably, the length of the second protruding member 221 is equal to L2, that is, the second protruding member 221 is a rib protruding from the third surface of the second connecting portion 22. The main reason for preferably setting the length of the first protruding member 211 to be equal to L1 and the length of the second protruding member 221 to be equal to L2 is that such a setting facilitates the manufacture of the first protruding member 211 and the second protruding member 221, and the structural strength of the connecting plate 2 will be better.

[0045] On the connecting plate 2, the first connecting portion 21, the second connecting portion 22, and the shielding portion 23 form a through groove, and the first protruding member 211 and the second protruding member 221 are located in the through groove. In this way, the first protruding member 211, the second protruding member 221, the connecting bolt 4, the fastener 5, etc. can be shielded by the shielding portion 23, making the lamp holder connection structure more beautiful.

[0046] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, provided that these changes fall within the scope of the claims of the present invention and their equivalent technologies, they still fall within the protection scope of the present invention.
