Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an easily detachable radiator for an LED lamp comprises two vertically corresponding ring structures, each ring structure is composed of two semicircular heat dissipation plates 1, the top end of the heat dissipation plate 1 at the upper part and the bottom end of the heat dissipation plate 1 at the lower part are respectively provided with a fixing block 6, the fixing blocks 6 correspond to fixing grooves 9 on a lamp 8, the bottom end of the heat dissipation plate 1 at the upper part and the top end of the heat dissipation plate 1 at the lower part are respectively provided with a telescopic cavity 101, a sealing frame 5 is arranged at the opening of the telescopic cavity 101, an arc-shaped connecting plate 2 is arranged between the vertically corresponding two telescopic cavities 101, and the connecting plate 2 runs through the sealing frame 5, the two ends of the connecting plate 2 are provided with arc-shaped moving plates 4, the telescopic springs 3 are arranged between the moving plates 4 and the cavity bottom of the telescopic cavity 101, and the radiating fins 7 are arranged on the outer side of the radiating plate 1.

Specifically, a plurality of extension springs 3 are arranged along the arc of the extension cavity 101 at equal intervals; so set up, make expanding spring 3 more even to the support of movable plate 4, avoid movable plate 4 to slide in flexible chamber 101, because of the inhomogeneous slope of atress, and then the card is inside flexible chamber 101, makes upper and lower two parts's heating panel 1 can not compress to connecting plate 2 direction.

Specifically, the width dimension of the moving plate 4 is equal to the thickness dimension of the telescopic cavity 101, so that the moving plate 4 is more stable when moving in the telescopic cavity 101, and the moving plate 4 is prevented from inclining when moving, so that the upper heat dissipation plate 1 and the lower heat dissipation plate 1 are inclined in a staggered manner.
