[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figure 1 - Figure 5 As shown, in this embodiment, a LED floodlight with waterproof and heat dissipation function includes an LED floodlight housing 1, which is characterized in that: two sliding grooves 14 are opened on one side of the interior of the LED floodlight housing 1, and the inner walls of the two sliding grooves 14 are slidably connected to sliding rods 13, one end of the two sliding rods 13 is rotatably connected to a disassembly screw 12, and the outer side walls of the two disassembly screws 12 are threadedly connected to the upper end of the LED floodlight housing 1, one side of the two sliding rods 13 is fixedly connected to two special-shaped push blocks 15, one end of the four special-shaped push blocks 15 is slidably connected to a fixed plug rod 10, one side of the LED floodlight housing 1 is clamped with the LED floodlight housing 2, and the LED floodlight Four fixing grooves 8 are provided on one side of the inner wall of the LED floodlight housing 2, and the interior of the four fixing grooves 8 are respectively slidably engaged with the outer side walls of the four fixing rods 10. The disassembly screws 12 are rotated by tools, and the disassembly screws 12 push the sliding rod 13 downward. One side of the special-shaped push block 15 pushes the fixing rod 10 outward so that one end of the fixing rod 10 is inserted into the fixing groove 8. The same operation is performed on the other disassembly screw 12 on the LED floodlight housing 1, thereby realizing the rapid fixation of the LED floodlight housing 2 in the LED floodlight housing 1. This structure is simple and easy to operate, which improves the efficiency of installation and disassembly of the floodlight. Moreover, this type of installation and disassembly can prevent the loss of the disassembly screws 12, making it easy to use.

[0023] like Figure 1 - Figure 4As shown, the outer wall of the LED floodlight housing 1 is rotatably connected to a rotating shaft 4, and the outer wall of the rotating shaft 4 is rotatably connected to a support frame 3. The support frame 3 can support the LED floodlight, and the projection angle of the LED floodlight can also be adjusted.

[0024] like Figure 1 - Figure 3 As shown, the inner wall of the LED floodlight housing 1 is fixedly connected with a plurality of heat dissipation fins 5, and the interior of the LED floodlight housing 1 is fixedly installed with an electronic component 9, and the outer wall of the electronic component 9 is in contact with one side of the heat dissipation fin 5. The heat generated by the operation of the electronic component 9 can be transferred to the outside of the LED floodlight housing 1 through the plurality of heat dissipation fins 5, thereby reducing the temperature.

[0025] like Figure 2 and Figure 3 As shown, a plurality of sealing strips 11 are fixedly connected to one side of the LED floodlight housing 1, and a plurality of sealing grooves 7 are opened on one side of the LED floodlight housing 2. The inner walls of the plurality of sealing grooves 7 are respectively slidably engaged with the outer walls of the sealing strips 11. Through the structural design of the sealing grooves 7 and the sealing strips 11, during installation, the plurality of sealing strips 11 are respectively inserted into the interior of the plurality of sealing grooves 7 to realize a labyrinth seal, thereby improving the waterproofness of the LED floodlight.

[0026] like Figure 1 and Figure 2 As shown, two disassembly grooves 6 are provided on the other side of the LED floodlight housing 2, and two disassembly screws 12 are respectively located inside the disassembly grooves 6. Through the structural design of the disassembly grooves 6, when the LED floodlight housing 2 is fixed to the LED floodlight housing 1, the tool can rotate the disassembly screws 12.

Two mounting grooves 18 are provided on the other side of the interior of the LED floodlight housing 1, and one side of the inner wall of the two mounting grooves 18 is fixedly connected to one end of the two return springs 17 respectively. Through the structural design of the return spring 17, when the restriction of the fixed plug rod 10 is released, the return spring 17 can pull the fixed plug rod 10 inward, release the restriction of the LED floodlight housing 2, and thereby remove the LED floodlight housing 2 from the LED floodlight housing 1.

[0028] The utility model provides an LED floodlight with waterproof and heat dissipation functions. The specific working principle is as follows:

[0029] When the LED floodlight is used for a long time and its internal equipment is damaged, the staff uses a tool to rotate the disassembly screw 12, and the disassembly screw 12 pulls the sliding rod 13 upwards, and the special-shaped push block 15 moves upwards to release the restriction of the fixed plug rod 10. The reaction force of the reset spring 17 pushes the fixed plug rod 10 inwards, so that the fixed plug rod 10 slides out of the fixing groove 8, and then rotates another disassembly screw 12 on the LED floodlight housing 1 to release the restriction of the LED floodlight housing 2, and remove the LED floodlight housing 2 from the LED floodlight housing 1, so as to repair the electronic components 9 in the LED floodlight housing 1. After the repair is completed, the electronic components 9 are placed in the LED floodlight The LED floodlight housing 2 is then covered on the LED floodlight housing 1 in the housing 1. Use tools to reversely rotate the removal screws 12. Remove the screws 12 to push the sliding rod 13 downward. One side of the special-shaped push block 15 pushes the fixed plug 10 outward so that one end of the fixed plug 10 is inserted into the fixing groove 8. The same operation is performed on the other removal screw 12 on the LED floodlight housing 1 to quickly fix the LED floodlight housing 2 in the LED floodlight housing 1. When the LED floodlight housing 2 is fixed on the LED floodlight housing 1, multiple sealing strips 11 are respectively inserted into the inside of the multiple sealing grooves 7, thereby forming a labyrinth seal, thereby improving the waterproofness of the LED floodlight.
