Description

A multi-functional street light Technical Field

[0001] This utility model relates to the field of street light technology, specifically to a multifunctional street light. Background Technology

[0002] In urban lighting systems, streetlights are an indispensable and crucial infrastructure, and their structural design directly affects lighting performance, safety, and ease of maintenance. Traditional multi-functional streetlights typically consist of a pole and a lamp head, with the lamp head further comprising a lamp housing and a component housing to accommodate the lighting fixtures and control elements. However, the existing connection structure between the streetlight pole and the lamp head has several shortcomings.

[0003] Currently, most streetlight poles and lamp heads are connected using snap-fit ​​connections or connecting sleeves to the pole assembly, secured with bolts. Over time, these connections are susceptible to external factors such as wind and vibration, leading to loosening of the connections and affecting the stability and lighting performance of the streetlight. Uneven stress distribution between the connecting sleeve and the pole, and the resulting high pressure on the connecting components, can also cause breakage and damage. Summary of the Invention

[0004] To address the shortcomings of the prior art, this utility model provides a multifunctional street light.

[0005] The technical solution adopted by this utility model is as follows: a multifunctional street light, including a lamp pole and a lamp head, the lamp head including a lamp box part and a component box part, the component box part being covered with a lid, and also including a connecting sleeve, one end of the lamp pole having a connecting section for connecting with the lamp head, the connecting section being provided with several stepped rings at equal intervals along the axial direction, the connecting sleeve including an upper half ring sleeve integral with the lid and a lower half ring sleeve integral with the component box part, after the lid is closed onto the component box part, a connecting hole for connecting with the connecting section is formed between the upper half ring sleeve and the lower half ring sleeve, and annular grooves that fit into the stepped rings are provided on the inner walls of the upper half ring sleeve and the lower half ring sleeve.

[0006] Furthermore, the component box portion is provided with a first wire through hole and a second wire through hole at both ends. The first wire through hole is used to communicate with the lamp box portion, and the second wire through hole is used to communicate with the connection hole.

[0007] Furthermore, the connecting segment is a cylindrical structure, and the connecting hole is a cylindrical hole adapted to it.

[0008] Furthermore, the gap between the stepped ring and the annular groove is less than 1 mm.

[0009] Furthermore, a sealing groove is provided on the upper surface of the component box portion, and a sealing ring is installed in the sealing groove.

[0010] Furthermore, the two ends of the upper surface of the component box and the two ends of the box cover are provided with matching first fixing holes, and the two sides of the upper half ring and the lower half ring are provided with connecting ears, and the connecting ears are provided with second fixing holes.

[0011] Furthermore, a warning label is provided on the bottom end face of the component box.

[0012] The beneficial effects of this utility model are:

[0013] 1. The connecting section of this application features multiple stepped rings on its outer edge, forming a stepped support surface. When the lamp head is connected to the connecting section of the lamp post via the connecting sleeve, this structure effectively distributes the forces such as the lamp head's own weight and wind load along the lamp post's axial direction. Compared to traditional connection methods, this avoids the drawback of a single connection point bearing excessive pressure, resulting in a more balanced stress on the lamp post and effectively reducing the risk of deformation or damage to the lamp post due to localized overload.

[0014] 2. The annular groove on the inner wall of the connecting sleeve and the stepped ring interlock, providing uniform axial and radial constraints for the connection between the lamp head and the lamp pole. This design ensures that the lamp pole and lamp head are subjected to uniform force in the circumferential direction, greatly reducing local stress concentration in the connecting sleeve, effectively preventing the connecting sleeve from cracking due to excessive local stress, significantly improving the reliability and durability of the street light connection structure, and extending the service life of the street light.

[0015] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
