[0002] In the field of urban road lighting and outdoor lighting, high altitude single -arm road lamp is widely used because of good lighting range and space utilization. Among them, the connecting structure of lampshade and lamp pole is the key component to ensure the normal work of road lamp and maintain the stability of lighting.

[0003] At present, the connecting mode of common high altitude single -arm road lamp lampshade and lamp pole mostly adopts simple bolt fixing. This connecting mode can realize the connection of lampshade and lamp pole to a certain extent, but there are many deficiencies in the actual use process. On the one hand, simply relying on bolt fixing, under the influence of external environmental factors such as wind force and vibration for a long time, loose phenomenon is easy to appear, which leads to lampshade shaking, not only affects the lighting effect, but also has safety hidden danger. On the other hand, the existing connecting structure lacks effective reinforcing support parts, the overall structural strength of the connecting part of lampshade and lamp pole is insufficient, it is difficult to withstand large external force impact, and the service life is short. In addition, the design of part of the connecting structure is unreasonable, the installation process is complicated, which increases the construction difficulty and maintenance cost. Therefore, it is urgent to design a high altitude single -arm road lamp lampshade and lamp pole connecting structure which is stable and reliable in connection, high in structural strength and convenient to install and maintain.

[0006] One end of the lamp pole connected with the lampshade is provided with a mounting plate, the mounting plate is provided with tapered fixing holes corresponding to the tapered columns, the tapered fixing holes are connected to the tapered columns with interference, and the tapered fixing holes are fixed through bolts after being connected to the tapered columns with interference;

[0007] A plurality of pairs of clamping plates are arranged at the bottom of the mounting plate, and a clamping groove is formed between each pair of clamping plates and clamped on both sides of the longitudinal reinforcing plate.

[0008] Further, a wire passing hole is formed between the longitudinal reinforcing plate and the mounting plate.

[0009] Furthermore, it also includes a welding block, and a thickening block is provided on one side of the mounting plate. The welding block is welded to the thickening block and the lamp post.

The light panel can be perfectly inserted into the annular step two and then installed on the mounting steps by bolts.

[0012] Furthermore, several heat dissipation grooves are arranged around the upper lamp housing located above the LED lamp group.

[0013] The beneficial effects of this utility model are:

[0014] Firstly, regarding the stability of the connection, the four rectangularly distributed conical columns on the lower lamp housing at the lampshade connection hole are interference-fitted with the conical fixing holes on the lamp post mounting plate, and further secured by bolts. This double-fixing method greatly enhances the connection strength between the lampshade and the lamp post, effectively resisting the influence of external environmental factors such as wind and vibration, avoiding loosening and shaking, and ensuring the stability and safety of the lighting effect.

[0015] Secondly, the transverse and longitudinal reinforcing plates installed between the tapered columns cooperate with the clamping plates at the bottom of the light pole mounting plate.

During installation, simply align the lamp post mounting plate with the lamp cover connection hole, make the tapered fixing hole interference fit with the tapered column, and then tighten the bolts. This reduces the difficulty of construction. At the same time, the clear structural design also facilitates later maintenance and repair, reduces maintenance costs, and achieves the technical effects of stable and reliable connection, high structural strength, and easy installation and maintenance.
