Description

Technical Field

[0001] The utility model belongs to the technical field of LED floodlights, and particularly relates to an installation structure of an LED floodlight. Background Art

[0002] LED generally refers to a light-emitting diode, which is a commonly used light-emitting device that emits light by the recombination of electrons and holes, and it is widely used in the lighting field.

[0003] Traditional LED floodlights mostly consist of a lamp board and a U-shaped bracket for adjustable support. When installing the LED floodlight on a crossbar and using it as a pendant lamp, the U-shaped bracket needs to be removed first, then the U-shaped bracket is hung on the crossbar, and then the lamp board is connected to the U-shaped bracket. When connecting, one hand needs to hold the lamp board and the other hand needs to hold a screwdriver for installation. However, this method is not convenient for single-person operation. Since the bolts are not fixed, it is easy for the bolts to fall off, affecting the installation progress.

[0004] Therefore, how to provide an installation structure for an LED floodlight is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure of an LED floodlight, aiming to solve the problems mentioned in the background art.

[0006] The utility model is implemented as follows. An installation structure of an LED floodlight includes:

[0008] A connecting plate, which is symmetrically and hingedly connected to the left and right sides of the back of the lamp board;

[0009] Chutes, which are symmetrically opened on the inner sides of the lower ends of the connecting plate;

[0010] A positioning rod, which is slidably installed inside the chutes on the left and right sides;

[0011] Side plates, which are arranged above the connecting plate;

[0012] An extension structure, which is arranged between the connecting plate and the side plates;

[0013] A connecting rod, which is movably arranged inside the top of the side plates.

[0014] Preferably, the extension structure includes a storage groove, a plug board, a rubber ring and a rotating block. The storage groove is opened in the middle of the upper end of the connecting plate. The plug board is fixedly installed at the bottom of the side plate and is movably inserted into the storage groove. A limiting groove is opened in the middle of the plug board. The rubber ring is arranged inside the limiting groove and is pasted on the middle of the top end of the storage groove on both the upper and lower sides. The rotating block is movably installed in the middle of the rubber ring, and positioning blocks are symmetrically installed on both sides. The front side of the rotating block penetrates through the surface of the connecting plate and is fixedly installed with an adjustment disk.

[0015] Preferably, placing grooves are symmetrically opened on the inner sides of the left and right side plates. A clamping groove is opened in the middle of the left placing groove, and a through hole is opened in the middle of the right placing groove. Positioning rings are symmetrically installed on both the left and right sides of the connecting rod. Plug rods are inserted into the middle of the clamping groove, the through hole and the connecting rod, and a limiting piece is fixedly installed on the right side. The plug rod is spirally connected with the through hole.

[0016] Preferably, when the positioning block is in movable contact with the front and rear sides of the rubber ring, the outer side of the rubber ring is in interference fit with the limiting groove.
