The present invention relates to a street lamp, and in particular to a coupling for the street lamp to be mounted on the coupling portion of the upper and lower circumference of the street lamp to enhance the cohesion between the struts and improve the aesthetics.

In general, streetlights are lighting facilities installed along the street for the safety and security of road traffic. When an external force such as a car crash is applied, the street lamp may be damaged or bend, which may threaten pedestrians or vehicles passing through the area where the shore is installed. Not only can the accident occur frequently, but also its power supply, traffic signal control, and night lighting can prevent the smooth flow of traffic in addition to the power cut in nearby areas.

Therefore, the street lamp post is manufactured so as to be separated into two or more of the lower column 1 and the upper column 2 so as to quickly repair or replace the broken column.

At this time, the lower column (1) and the upper column (2) is to be welded to make a more firm coupling, there is a fear that the welding portion (3) is exposed to the outside to damage the aesthetics.

Accordingly, the same applicant of the present invention has devised a streetlight coupler for preventing the welding portion of the street lamp to be exposed to the outside and the coupling portion is more robust, the schematic configuration is as shown in FIG.

That is, the coupler is a plurality of outer ring 10 having a predetermined width vertically stacked arranged, the inner surface of each outer ring 10 is provided with a vertical support 20 of the hollow body to form a triangle.

And, inside each of the outer ring 10 is provided with an inner ring 30 for supporting the upper support (2) of the street lamp, the inner ring 30 to the horizontal connection 40 is arranged triangular at equal intervals By the outer ring 10 is firmly coupled.

However, in some cases, the upper column may be curved or bent due to effects such as an aesthetic effect. In this case, the upper column may not be mounted when the assembly is completed between the upper column and the lower column. And there is a problem that must be combined before the assembly of the lower column (1) is completed.

The present invention is to solve this problem, and to prevent the exposed portion of the upper column and the lower column is exposed, and to provide a street light coupler for easy mounting even after the completion of assembly of the upper column and the lower column. Its purpose is.

Coupler for street lamps according to the present invention for achieving the above object, in the coupler for street lamps coupled to the outer ring and the inner ring is coupled by a horizontal support a plurality of couplers connected to the horizontal connection, the coupler is a vertical support On the basis of the symmetrical separation on both sides, the vertical support of one side coupling half is formed with a sliding groove in the longitudinal direction, the vertical support of the other half coupling is characterized in that the sliding projection is inserted into the sliding groove is formed.

Hereinafter, described with reference to the accompanying drawings, the coupling device for a street lamp according to the present invention.

2 and 3 show a first embodiment of the present invention, the coupling for the street lamp 3 of the present embodiment is a plurality of outer ring 10 having a predetermined width vertically stacked, each outer ring Inside the 10, four vertical supports 20 are provided at equal intervals.

In addition, an inner ring 30 for supporting the upper column 2 of the street lamp is provided with a smaller width than the outer ring 10 inside each outer ring 10, and the inner ring 30 is vertically supported. It is firmly coupled to the outer ring 10 by a horizontal connector 40 disposed at the same position as the (20).

Here, the coupling sphere (3) of the present invention may be each laminated vertically coupled, and also is cut on the basis of the opposite vertical support 20 is formed to be separated from both left and right.

That is, a sliding groove 21 is formed in one vertical support in a longitudinal direction, and a sliding protrusion 22 is formed in the other vertical support so as to correspond to the sliding groove 21. After positioning, the two half coupling spheres can be simply fastened to the street lamp post by vertically inserting the sliding protrusions 22 of the other half of the coupling sphere so as to correspond to the sliding grooves 21.

On the other hand, it is preferable that the stop jaw 25 is formed at the lower end of the sliding groove 21 so that the sliding projection 22 is not separated downward when the coupling members of the symmetrical coupling.

Such a coupler can further increase the coupling force between the upper support (2) and the lower support (1), the inner ring 30 and the outer ring 10 to the upper support (2) and the lower support (1) It is possible to prevent the welding portion 3 from being exposed to the outside, so as not to reduce the aesthetics of the street light.

4 and 5 show a second embodiment of the present invention, in this embodiment, the coupling groove 23 is formed in the vertical support 20 of one side semi-circular coupling, and the vertical support 20 of the other semi-circular coupling is Coupling protrusion 24 is formed to be protruded to be inserted into the coupling groove (23).

At this time, through holes 23a and 24a are formed at the same height in the coupling groove 23 and the coupling protrusion 24, respectively, and fixing screws B are formed in the respective through holes 23a and 24a. Is combined.

Therefore, the semicircular couplers, which are symmetrical with each other, in which a plurality of outer rings 10 are laminated, can be firmly coupled to each other by a fixing screw B.

On the other hand, the method of forming the through-holes and fastening the fixing screw in each vertical support separated as in this embodiment is also applicable to the coupling of the first embodiment in which the sliding groove and the sliding projection is formed in each vertical support.

6 and 7 show a third embodiment of the present invention, the bifurcation of the coupler (3) so as not to interfere with the vertical support 20 and the horizontal connector 40, but each reinforcement inside the semicircular outer ring (11) is formed, a predetermined support groove 12 in the transverse direction is formed in the reinforcement portion 11 of one side semi-circular coupler, and the support protrusion 13 is formed to protrude horizontally in the reinforcement portion 12 of the other semi-circular coupler. do.

Therefore, when the support protrusion 13 is inserted and coupled to the support groove 12, each of the separated outer rings is coupled to each other, it is possible to maintain more excellent robustness by the respective reinforcing portion (12).

At this time, the support groove 12 and the support protrusion 13 is formed with a screw hole (12a) (13a) in a position corresponding to each other can be fastened the fixing screw (B) for a more secure coupling.

As described above, according to the present invention, the coupling portion is mounted on the outside of the street lamp to further strengthen the coupling force between the upper and lower supports constituting the street lamp, and also the weld between the upper and lower supports is not exposed to the outside. Not only does it reduce the aesthetics of the street lamp, but also makes the coupling tool detachable to both the left and right sides, thereby facilitating fastening with the street lamp post.
