Abstract
The utility model discloses a road lamp of which the lamp post cross section is not round. The utility model comprises a base, a lamp post, a post end, a transmission line and a luminous element, wherein the cross section of the lamp post is of a gear shape, a corolla shape and a rectangle shape formed by a plurality of bulges and recesses; the bulges and the recesses extend the whole length of the lamp post. Because the outer surface and the inner surface of the lamp post are provided with a plurality of bulges and recesses, under the condition of the coordinate material, the utility model enlarges the diameter dimension of the maximal position, enhances the mechanical strength and the anti-bending intensity of the lamp post, and particularly enhances the capability of resisting natural disasters such as strong storm, etc. Compared with the prior art, the utility model has the characteristics of simple production technology, low investment of equipment, low production cost and high mechanical strength.
Description
Technical field:
The utility model relates to the street lamp of road lighting, and especially the cross section of lamp stand is non-circular street lamp.
Background technology:
The lamp stand of existing road lighting street lamp adopts conical rod mostly, for polygon prismatic awl bar has also appearred in the mechanical strength that improves rod member.Because the processing of polygon prismatic awl bar need be passed through multiple working procedures such as blanking, bending, welding, corollary equipment is many, and equipment investment is excessive, complex manufacturing, member bending distortion, percent defective height often take place because of the effect of welding stress in the long pole through welding, waste of material is big, the cost of production height.
Summary of the invention
The purpose of this utility model is: provide a kind of mechanical strength height, the low lamp stand of create an aesthetic feeling again of cost of production.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that the external surface of cross section of lamp stand is by a plurality of uniform projectioies and the whole length that ， And extends to lamp stand that depression is formed.
As preferably, a plurality of projectioies of the external surface of the cross section of lamp stand and depression are gear shape, corolla shape, rectangle, and the inner surface of cross section is consistent with the shape of the external surface of the cross section of lamp stand.
The beneficial effects of the utility model are: a plurality of projectioies of the external surface of lamp stand and inner surface and depression have realized under the situation of equivalent material, strengthened the diameter dimension of maximum, the mechanical strength and the resistant to bending intensity of lamp stand have been improved, particularly improved the ability of natural calamities such as opposing strong storm, compared with prior art, has simple, the low equipment investment of production technology, the characteristics that cost of production is low, mechanical strength is high.
