The upper end of the support rod includes an LED lighting head arranged obliquely upward. A fixing groove is arranged upward on the lower end surface of the support rod. The upper end of the fixing column is inserted into the fixing groove. The inner side wall of the fixing groove extends downward to below the fixing plate. Two groups of opposite openings are arranged at the lower part of the inner side wall of the fixing groove. Bolts are arranged at the openings. After the bolts pass through the four openings on the two inner side walls, nuts are screwed.

[0006] A further improvement of the LED lighting street lamp of the utility model is that a positioning nut is screwed on the outer side of the lower part of the fixing column, and the upper end surface of the nut abuts against the fixing plate.

[0007] A further improvement of the LED lighting street lamp of the utility model is that threads are also provided on the lower part of the outer side wall of the support rod, and a second positioning nut is screwed. The lower end surface of the second positioning nut abuts against the fixing plate. A waterproof gasket is arranged between the positioning nut, the second positioning nut and the fixing plate.

[0008] A further improvement of the LED lighting street lamp of the utility model is that the fixing plate and the bottom column are integrally formed, and the thickness of the fixing plate is greater than the wall thickness of the bottom column.

[0009] A further improvement of the LED lighting street lamp of the present utility model lies in that a threaded hole is provided on the fixed column, and a fastener is provided at the threaded hole, and the fastener abuts against the inner side wall of the fixed groove.

[0010] Compared with the prior art, the beneficial effects of the present utility model are:

[0011] The present utility model limits the support rod through the fixed column to achieve stable connection of the support rod, ensure the fixed layout of the lighting lamp head, is convenient for disassembly and installation, has a simple and stable structure; is conducive to step-by-step production and transportation, and improves efficiency. Description of the Drawings

[0012] Figure 1 is a structural schematic diagram of the present utility model;

[0013] In the figure: 1 bottom column, 2 fixed plate, 3 support rod, 4 LED lighting lamp head, 5 fixed column, 6 inner side wall, 7 bolt, 8 positioning nut. Specific Embodiments

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] As Figure 1 shown, an LED lighting street lamp includes a cylindrical bottom column 1. An upper end of the bottom column is provided with a fixed plate 2, and a lower end is provided with a mounting plate. Two groups of fixing holes are provided on the fixed plate. Threads are provided in the fixing holes and a fixed column 5 is screwed therein. Upper and lower ends of the fixed column respectively protrude from the fixed plate. A support rod 3 is arranged above the fixed plate. An upper end of the support rod includes an LED lighting lamp head 4 arranged obliquely upward. A fixed groove is provided upward on a lower end surface of the support rod. An upper end of the fixed column is inserted into the fixed groove. An inner side wall 6 of the fixed groove extends downward to below the fixed plate. Two groups of opposite openings are provided at a lower part of the inner side wall of the fixed groove. Bolts 7 are provided at the openings. After the bolts pass through four groups of openings on the two groups of inner side walls, nuts are screwed thereon. The bolts are used to limit the support rod to ensure the stability of the layout of the support rod, and further realize the stable layout of the LED lighting lamp head.

[0016] Further, a positioning nut 8 is screwed on an outer side of a lower part of the fixed column, and an upper end surface of the nut abuts against the fixed plate. Threads are also provided on a lower part of an outer side wall of the support rod, and a second positioning nut is screwed thereon. A lower end surface of the second positioning nut abuts against the fixed plate. Waterproof gaskets are provided between the positioning nut, the second positioning nut and the fixed plate. While further ensuring the stability of the fixed column, further waterproofing is also achieved.

[0017] The fixing plate and the bottom column are integrally formed, and the thickness of the fixing plate is greater than the wall thickness of the bottom column. The relatively thick fixing plate can ensure the stability of the connection of the fixing column.

[0018] Threaded holes are provided on the fixing column, and fasteners are provided at the threaded holes. The fasteners abut against the inner side wall of the fixing groove.

[0019] The working principle of the present utility model is as follows: The LED lamp head, the fixing column, and the bottom column are respectively manufactured and transported to the installation position. After installing the bottom column, the fixing column is arranged, and then the support rod is inserted. Then, the support rod is further positioned and limited through the inspection door provided on the side wall of the bottom column. The overall structure is simple, the disassembly and assembly are convenient, and at the same time, the structural stability is ensured.
