The end of the cover plate 200 is provided with a sleeve 210 for connection with a pole of a street light so that the street light can be suspended in the air.

Referring to fig. 2 and 4, the heat sink 100 is provided with an accommodating cavity 110, an end of the cover plate 200 extends into the accommodating cavity 110, and the heat sink 100 is rotatably connected with the cover plate 200. Specifically, the cover plate 200 is provided with a first baffle 220, a second baffle 230 and a third baffle 240, the first baffle 220 is located between the second baffle 230 and the third baffle 240, and the three baffles are integrally connected with the cover plate 200. The plug 500 includes an insertion portion 510 and a position-limiting portion 520, wherein the insertion portion 510 is bent at a certain angle relative to the position-limiting portion 520 and integrally connected to each other. The insertion portion 510 is further provided with a holding portion 700, in this embodiment, the holding portion 700 is a snap spring, and a placement groove (not shown) is provided on the outer surface of the insertion portion 510, and the snap spring is fixed in the placement groove. An elastic member 600 is further sleeved on the insertion portion 510 between the abutting portion 700 and the first baffle 220, in this embodiment, the elastic member 600 is a spring. The connection plate 400 is fixedly connected to the heat sink 100 by screws, and the connection plate 400 is provided with a first pin hole 410.

The first baffle 220 and the second baffle 230 are both provided with hole locations (wherein, the hole location on the first baffle 220 is a second bolt hole), and the insertion portion 510 sequentially passes through the hole locations on the first baffle 220 and the second baffle 230 and then is inserted into the first bolt hole 410 on the connecting plate 400. The position-limiting portion 520 is located between the first blocking plate 220 and the third blocking plate 240. The elastic member 600 is in a compressed state, and the direction of the resilient force is from the center to both ends (along the axial direction), so that the first end of the elastic member 600 elastically abuts against the first baffle 220, and the second end elastically abuts against the abutting portion 700, so as to push the insertion portion 510 fixedly connected with the abutting portion 700 toward the first pin hole 410 on the connection plate 400, so that the insertion portion 510 cannot exit from the first pin hole 410. Meanwhile, the other side of the supporting portion 700 is supported by the second blocking plate 230, and the limiting portion 520 integrally connected with the inserting portion 510 is supported by the first blocking plate 220.

As can be seen from the above, the heat sink 100 is sleeved on the insertion portion 510 through the connection plate 400, and the cover plate 200 is sleeved on the insertion portion 510 through the first baffle 220 and the second baffle 230, so that a rotation pair is formed between the heat sink 100 and the cover plate 200, and the two can rotate relatively. The heat sink 100 can be opened or closed by rotating relative to the cover plate 200.

Preferably, referring to fig. 2, 4 and 7, the pressing plate 800 is fixedly coupled to the cover plate 200 by screws.

When the heat sink 100 rotates relative to the cover plate 200, the second arc surface 251 contacts with different areas on the first arc surface 430, and the two are always in a fit state, so that the connecting plate 400 is supported to a certain extent, and the two can rotate relatively more stably.

Referring to fig. 3, 4 and 10, when the heat sink 100 and the cover plate 200 need to be separated for maintenance, the latch 500 is rotated to make the limiting portion 520 stand upward, and the latch 500 is pulled to overcome the resilience of the elastic member 600, so that the insertion portion 510 is withdrawn from the first latch hole 410 of the connection plate 400, and the rotational connection relationship between the heat sink 100 and the cover plate 200 is released. At this time, the heat sink 100 is pulled away from the cover plate 200 until the cover plate 200 is withdrawn from the receiving cavity 110, so that the two can be completely separated. The plug 500 is pulled out to the outside of the third barrier 240, and the stopper 520 is blocked by the third barrier 240, so that the insertion portion 510 is prevented from being inserted into the first plug hole 410 again by the resilient force of the elastic member 600. Preferably, the third barrier 240 is provided with a notch 241 so that the insertion portion 510 can pass through. Of course, the entire third baffle 240 may be directly disposed on one side of the insertion portion 510, and in this case, the notch 241 is not required.
