Description

Technical Field

[0001] The utility model relates to the technical field of LED floodlights, in particular to a rotary LED floodlight with a protective hanging chain. Background Art

[0002] A floodlight is a point light source that can illuminate evenly in all directions. It produces highly diffuse, directionless light rather than a clearly defined beam of light. It has no electrodes and emits light by combining the principles of electromagnetic induction and fluorescent discharge. Therefore, it has no necessary components that limit its lifespan. The shadows it produces are soft and transparent. When used to illuminate objects, the speed at which the illumination fades is much slower than when using a spotlight. Some floodlights with very slow illumination decay even look like a light source that produces no shadows.

[0003] When installing the lamp body, the installation is completed through the mounting frame. However, the existing lamp body is damaged when it is subjected to strong vibration. The elastic structure is installed to buffer the vibration of the lamp body. However, the elastic structure will also cause the lamp body to shake when it is subjected to small vibrations. Small vibrations are more common in reality, and the damage to the lamp body can be ignored. On the contrary, frequent vibrations caused by small vibrations of the lamp body are more likely to cause damage to the inside of the lamp body. To this end, we provide a rotating LED floodlight with a protective hanging chain to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-6As shown, the utility model provides a technical solution: a rotating LED floodlight with a protective hanging chain, comprising a light source lamp body 1, a fixing frame 2 is installed on the upper surface of the light source lamp body 1, a control frame 3 is arranged above the fixing frame 2, a horizontal box 4 is arranged between the control frame 3 and the fixing frame 2, the bottom surface of the horizontal box 4 is fixedly connected to the fixing frame 2, a vertical cylinder 12 is fixedly installed on the right end of the horizontal box 4, a cross plate 5 is arranged on the front and rear sides of the horizontal box 4, the left and right ends of the cross plate 5 are fixedly connected with a hollow cylinder 6, the upper end of the hollow cylinder 6 is fixedly connected to the control frame 3, and the hollow cylinder 6 is fixedly connected to the control frame 3. An inner rod 7 is slidably inserted inside, and the lower end of the inner rod 7 is fixedly connected to the fixing frame 2. Two supporting springs 16 are arranged inside the hollow cylinder 6. The two ends of the supporting spring 16 are respectively fixedly connected to the inner rod 7 and the inner wall of the hollow cylinder 6. The two supporting springs 16 located in the same hollow cylinder 6 have the same length. The hollow cylinder 6 is coaxially arranged with the connected inner rod 7. The inner rod 7 is located on the inner ring side of the supporting spring 16. A card slot 15 is provided on the side close to each other of the two cross plates 5. A plug plate 8 is arranged inside the two card slots 15. The ends of the two plug plates 8 close to each other are respectively slidable. The front and back sides of the horizontal box 4 are splayed, and one end of the slot 15 close to the horizontal box 4 is in an eight-shaped shape, and the other end of the slot 15 is concave and the inner wall thickness is equal to the thickness of the plug plate 8. The support spring 16 has a tendency to drive the plug plate 8 to be in the concave shape of the slot 15 through the inner rod 7. A fixed width block 9 is inserted into the interior of the horizontal box 4 for sliding sliding. The left end of the fixed width block 9 is elastically connected to the left inner wall of the horizontal box 4 by a tension spring 10. The middle position of the fixed width block 9 gradually shrinks from right to left. The left end width of the fixed width block 9 is less than the right end width of the fixed width block 9. When the smaller end of the fixed width block 9 moves to the plug plate 8 When the plug plate 8 is in the slot 15, the fixed frame 2 cannot move relative to the control frame 3, so that the light source lamp body 1 will not shake. The two plug plates 8 are coaxially arranged, and the plug plates 8 are perpendicular to the cross box 4. The end of the plug plate 8 close to the fixed width block 9 is rotatably embedded with a ball 14, and the ball 14 reduces the resistance encountered by the plug plate 8 and the fixed width block 9 when they move relative to each other.

[0027] A gravity ball 11 is slidably inserted inside the vertical tube 12, and a balancing spring 18 is fixedly connected to the upper and lower surfaces of the gravity ball 11. When the gravity ball 11 is shaken, the balancing spring 18 is elastically deformed. The other end of the balancing spring 18 is fixedly connected to the inner wall of the vertical tube 12. The gravity ball 11 is located in the middle position of the vertical tube 12. The two balancing springs 18 are of equal length. The right end of the fixed width block 9 is fixedly connected to a long rope 13. The other end of the long rope 13 slides through the outer surface of the vertical tube 12. The right end of the long rope 13 is fixedly connected to the gravity ball 11. When the gravity ball 11 shakes, the fixed width block 9 is driven to move rightward through the long rope 13. The plug plate 8 is elastically connected to the horizontal box 4 through the elastic telescopic rod 17. The elastic telescopic rod 17 has a tendency to pull the plug plate 8 close to the horizontal box 4. The axis of the vertical tube 12 is arranged parallel to the axis of the hollow tube 6, and the two cross plates 5 are symmetrically distributed front and back about the axis of the horizontal box 4, so that the force on both sides of the light source lamp body 1 is uniform.

[0028] Working principle: When the amplitude is small, the swing amplitude of the gravity ball 11 is small. At this time, the plug board 8 contacts the widest surface of the fixed width block 9, so that the plug board 8 is inserted into the card slot 15. At this time, the hollow cylinder 6 cannot move relative to the inner rod 7, so that the light source lamp body 1 installed under the fixing frame 2 will not shake when subjected to a small amplitude vibration. When the light source lamp body 1 is subjected to a strong vibration, the gravity ball 11 drives the balance spring 18 to deform to a longer length, and the fixed width block 9 is pulled to the right by the long rope 13. The distance becomes larger, and the smaller end of the fixed width block 9 moves to the position where it is installed on the plug board 8. When the ball 14 is installed, the plug plate 8 is separated from the concave structure of the slot 15 under the pull of the elastic telescopic rod 17. At this time, the inner rod 7 can move relative to the hollow tube 6, and the light source lamp body 1 drives the supporting spring 16 to elastically deform through the inner rod 7, so as to buffer and reduce the vibration of the light source lamp body 1. After the vibration is lower, the supporting spring 16 drives the cross plate 5 to reset by pushing the inner rod 7. At the same time, the balancing spring 18 pushes the gravity ball 11 to reset. The tension spring 10 pulls the fixed width block 9 to move to the left, pushing the plug plate 8 to be reinserted into the slot 15.
