Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 7 As shown, an easily adjustable LED floodlight includes a base 1, which facilitates the installation and fixation of the entire device. A mounting bracket 2 is provided above the base 1, and the LED floodlight body 3 is movably mounted on the mounting bracket 2.

[0027] The mounting frame 2 includes two vertically extending square tubes 4 arranged opposite each other. The square tubes 4 are hollow. A connecting plate 5 is fixed to the lower ends of the two square tubes 4 by bolts or welded to improve the stability of the mounting frame 2. The LED floodlight body 3 is located above the connecting plate 5. Two vertically extending sliding rods 6 are fixed to the top of the base 1 by bolts. The sliding rods 6 correspond one-to-one with the square tubes 4. The square tubes 4 are fitted over the corresponding sliding rods 6. Sliding sleeves 7 that match the sliding rods 6 are fixed to the upper and lower ends of the square tubes 4 by bolts, so that the mounting frame 2 and the LED floodlight body 3 can slide up and down along the sliding rods 6.

[0028] like Figure 2 and Figure 3As shown, in order to facilitate the height locking of the mounting frame 2 and the LED light body 3, the outer wall of the two square tubes 4 away from each other is respectively fixed with a sliding column 29 extending transversely, and specifically, the sliding column 29 on each square tube 4 is arranged in a rectangular array with four sliding columns 29, one end of the sliding column 29 is connected to the square tube 4 by screwing, and four sliding columns 29 are commonly slidably installed with an adjusting plate 8, the side of the adjusting plate 8 close to the square tube 4 is welded with a transversely extending bolt 9, the outer wall of the square tube 4 is provided with a through hole 10 for the bolt 9 to pass through, and the sliding rod 6 is provided with a slot 11 matched with the bolt 9, by inserting the bolt 9 into the slot 11, the sliding of the square tube 4 along the sliding rod 6 is limited, and the height of the mounting frame 2 and the LED light body 3 is kept fixed.

[0029] In addition, the end of the sliding column 29 away from the square tube 4 is welded with a stop head 12, which can prevent the adjusting plate 8 from falling off the sliding column 29, and the sliding column 29 between the stop head 12 and the adjusting plate 8 is sleeved with a first spring 13, which gives the adjusting plate 8 a pushing force towards the square tube 4, thereby avoiding the bolt 9 from accidentally separating from the slot 11.

[0030] In order to facilitate the adjustment of the LED light body 3 to different heights, a plurality of slots 11 are vertically and uniformly spaced on the sliding rod 6.

[0031] In order to facilitate the pulling of the bolt 9 out of the slot 11, the side of the adjusting plate 8 away from the square tube 4 is welded with a pull ring 30.

[0032] Specifically, when the installation height of the LED light body 3 needs to be adjusted, the pull ring 30 is pulled outwards to drive the bolt 9 to separate from the slot 11 against the pushing force of the first spring 13, and then the mounting frame 2 can be slid up and down along the sliding rod 6 to raise or lower the LED light body 3, avoiding the existence of obstacles in front of the LED light body 3 affecting the lighting effect of the LED light body 3. After adjusting the LED light body 3 to the appropriate height, the pull ring 30 is released, and then the first spring 13 pushes the adjusting plate 8 to move towards the side close to the square tube 4 and drives the bolt 9 to insert into the aligned slot 11, thereby relocking the height of the mounting frame 2 and the LED light body 3.

[0033] The LED floodlight body 3 has two horizontally extending rotating shafts 14 fixedly mounted on its left and right sides by screws. The two rotating shafts 14 are coaxially arranged and are rotatably mounted inside the corresponding square tubes 4 via bearings. The illumination angle of the LED floodlight body 3 is adjusted by rotating it around the axis of the rotating shafts 14. Mounting plates 15 are also fixedly mounted on the left and right sides of the LED floodlight body 3 above the rotating shafts 14 by screws. Sliding pins 16, which are parallel to the rotating shafts 14, are fixedly mounted on the opposite sides of the two mounting plates 15. Limiting plates 17 are fixedly mounted on the rear sides of the two square tubes 4 by bolts. The limiting plates 17 have arc-shaped slots 18 that match the sliding pins 16. The arc-shaped slots 18 extend through the limiting plates 17 along the length of the sliding pins 16, and the center of the arc-shaped slots 18 coincides with the axis of the rotating shafts 14. The sliding pins 16 are slidably mounted in the corresponding arc-shaped slots 18, and a locking mechanism is provided between the sliding pins 16 and the corresponding limiting plates 17.

[0034] like Figures 5 to 7 As shown, in this embodiment, the locking mechanism includes a movable block 19 slidably mounted on a sliding pin 16. The movable block 19 is cylindrical in shape. A mounting hole 20 for the sliding pin 16 to pass through is provided at the axis of the movable block 19. A guide groove 21 extending along its length is provided on the outer wall of the sliding pin 16. A guide block 22 matching the guide groove 21 is integrally formed on the inner wall of the mounting hole 20, which can prevent the movable block 19 from rotating around the sliding pin 16. A circular positioning disk 23 is integrally formed on one end of the movable block 19 near the LED floodlight body 3. A rod 24 is fixedly mounted on the side of the positioning disk 23 near the LED floodlight body 3. A socket 25 for inserting the rod 24 is provided on the limiting plate 17. By inserting the rod 24 into the socket 25, the rotation of the LED floodlight body 3 around the axis of the rotating shaft 14 is restricted, so that the illumination angle of the LED floodlight body 3 remains fixed.

[0035] In this embodiment, multiple insertion holes 25 are evenly spaced around the axis of the rotating shaft 14, which facilitates the adjustment of the LED floodlight body 3 to different angles. The positioning plate 23 is provided with two insertion rods 24, which are distributed at 180 degrees around the axis of the movable block 19. The limiting plate 17 is provided with two rows of insertion holes 25 arranged in an arc shape. The two rows of insertion holes 25 are located on the inner and outer sides of the arc-shaped slot 18, respectively. The two rows of insertion holes 25 correspond to the two insertion rods 24, and the two insertion rods 24 are inserted into the corresponding insertion holes 25, thereby making the angle of the LED floodlight body 3 more stable.

[0036] In the embodiment, the slide pin 16 is fixedly installed with a baffle 26 at one end away from the LED spotlight body 3 by a bolt, so that the movable block 19 can be prevented from completely separating from the slide pin 16; the slide pin 16 between the baffle 26 and the movable block 19 is sleeved with a second spring 27, so that the plug rod 24 can be prevented from accidentally separating from the insertion hole 25; the movable block 19 is provided with a recess 28 at one end away from the LED spotlight body 3, and the baffle 26 and the second spring 27 are all received in the recess 28.

[0037] In use, the movable block 19 is pulled outward to drive the plug rod 24 to separate from the insertion hole 25 against the elastic force of the second spring 27, and then the LED spotlight body 3 can be rotated to be adjusted; after the LED spotlight body 3 is adjusted to a proper angle, the movable block 19 is loosened, the second spring 27 pushes the movable block 19 to move towards the LED spotlight body 3 and makes the plug rod 24 inserted into the insertion hole 25 aligned at this time, so that the angle of the LED spotlight body 3 is re-locked.
