Technical Field

[0001] This utility model relates to the field of street light technology, specifically to a modular double-headed street light structure. Background Technology

[0002] On roads, dual-headed streetlights are generally used to ensure lighting for both motor vehicle lanes and sidewalks. A Chinese utility model patent with application number 202323287220.0 discloses an LED streetlight that uses two sets of light poles with connecting parts to reduce transportation costs. However, the design of these two sets of light poles in this structure results in resource waste and leaves room for improvement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a stable and resource-saving modular dual-head street light structure.

[0004] To achieve the above objectives, this utility model provides an assembled dual-head street light structure, which adopts the following technical solution:

[0005] A modular dual-head street light structure includes a light pole with a vertically downward elongated notch on the upper part of the pole wall. The inner side wall of the upper end of the light pole is threaded, and a first lighting head is screwed into the thread. A fixing plate is inserted into the notch, and a second lighting head is arranged on the fixing plate. The left, right, and bottom ends of the fixing plate are provided with fixing grooves that fit into the notch. The inner side wall of the upper part of the fixing plate is provided with a recess to avoid the screwed part of the first lighting head.

[0006] A further improvement of the present invention for a modular double-headed street light structure is that the first lighting head includes a positioning plate, a screw connection part for screwing the light pole is provided below the positioning plate, and a lighting head is provided above the positioning plate. The positioning plate is in contact with the upper end face of the light pole, and the area of ​​the positioning plate is larger than the cross-sectional area of ​​the light pole.

[0007] A further improvement of the modular double-headed street light structure of this utility model is that a positioning groove is provided on the lower end face of the positioning plate, and a positioning pin plate for inserting into the positioning groove is provided on the outer side of the fixing plate.

[0008] A further improvement of the modular double-headed street light structure of this utility model is that a second concave portion is provided on the upper outer side of the fixing plate. The cross-section of the second concave portion is L-shaped. A sliding groove is provided on the vertical side wall of the second concave portion. The positioning pin plate is provided with a sliding part that slides in the sliding groove. A slot is provided on the lower end face of the positioning pin plate and the horizontal bottom wall of the second concave portion. A limiting plate is provided at the slot. The limiting plate is used to lift the positioning pin plate and lock it into the positioning slot.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model enables the installation of double-headed streetlights by creating notches on the light pole and adding threads to the upper part of the light pole. On the one hand, the structure is simple and easy to install, and on the other hand, it reduces the use of fasteners. At the same time, the first lighting structure is also limited by the fixing plate and positioning pin plate in the second lighting structure, which further ensures the stability of the overall lighting structure.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 and Figure 2 As shown, a modular dual-head street light structure includes a lamp post 1, which is cylindrical. The upper part of the lamp post has a vertically downward-pointing elongated notch 2. The inner side wall of the upper end of the lamp post has threads, and a first lighting head 3 is screwed onto the threads. A fixing plate 4 is inserted into the notch, and a second lighting head 5 is mounted on the fixing plate. Specifically, the left and right sides and the bottom end of the fixing plate have fixing grooves 6 that engage with the notch of the lamp post. The inner side wall of the upper part of the fixing plate has a recess 7, which is used to avoid the screwed portion of the first lighting head. The fixing plate is preferably an arc-shaped plate to fit the circular lamp post.

[0017] The first lighting head includes a positioning plate 8, with a screw connection part 9 for screwing the lamp post below the positioning plate and a lighting head above the positioning plate. The positioning plate contacts the upper end face of the lamp post, and the area of ​​the positioning plate is larger than the cross-sectional area of ​​the lamp post. Furthermore, a positioning groove is provided on the lower end face of the positioning plate, and multiple sets of positioning grooves can be provided for easy adjustment and application. A positioning pin plate 10 is provided on the outer side of the fixing plate for inserting into the positioning groove.

[0018] Specifically, the upper outer side of the fixing plate is provided with a second recess, the cross-section of which is L-shaped. A groove 13 is provided on the vertical side wall of the second recess, which can be a T-shaped groove. The positioning pin plate is provided with a sliding part that slides in the groove. A slot 12 is provided on the lower end face of the positioning pin plate and the horizontal bottom wall of the second recess. A limiting plate 11 is provided at the slot, which is used to lift the positioning pin plate and lock it into the positioning slot.

[0019] The working principle of this utility model is as follows: During installation, the fixing plate is first installed at the notch, that is, the second lighting structure is installed. Then the first lighting structure is installed. After it is in place, the limiting plate is set up so that the limiting plate locks the fixing plate and the positioning pin plate. At this time, the positioning pin plate is locked into the positioning groove on the positioning plate to achieve stable limiting.
