DETAILED DESCRIPTION

[0022] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 4 As shown: A lighting lamp capable of achieving multi-degree-of-freedom adjustment includes a lamp stand 1 located at a high position and an operating frame 2 located at a low position. A U-shaped frame 3 is rotatably connected to the lamp stand 1, and a lighting lamp body 4 is rotatably connected to the U-shaped frame 3. A first spring 5 is connected between the bottom of the lighting lamp body 4 and the U-shaped frame 3. A tail plate 6 is provided at the tail of the lighting lamp body 4, and a first cable 7 is connected to the middle of the tail plate 6. A first wheel frame 8 is also provided on the lamp stand 1 and is located below the U-shaped frame 3. A first guide wheel 9 is rotatably supported on the first wheel frame 8.

[0023] A first drive shaft 10 is rotatably supported on the operating frame 2. The bottom end of the first cable 7 is connected to the first drive shaft 10. The first cable 7 is also guided by the first guide wheel 9. A first worm gear 11 is provided at the end of the first drive shaft 10. A first worm 12 meshing with the first worm gear 11 is rotatably supported on the operating frame 2.

[0024] The two sides of the tail end of the tail plate 6 are respectively connected to a second spring 13 and a second cable 14, wherein the other end of the second spring 13 is connected to one side of the lamp frame 1, and a second wheel frame 15 is provided on the other side of the lamp frame 1, and a second guide wheel 16 is rotatably supported on the second wheel frame 15.

[0025] A second drive shaft 17 is rotatably supported on the operating frame 2, and the bottom end of the second cable 14 is connected to the second drive shaft 17. At the same time, the second cable 14 is also guided by a second guide wheel 16. A second worm gear 18 is provided at the end of the second drive shaft 17, and a second worm 19 that meshes with the second worm gear 18 is rotatably supported on the operating frame 2.

[0026] The lamp holder 1 has four base plates with first mounting holes 20 at their four corners.

[0027] Second mounting holes 21 are formed at four corners of the base plate of the operating frame 2 .

[0028] A first connecting hole 22 is defined in the middle of the tail plate 6 , and the end of the first cable 7 is connected to the first connecting hole 22 . A second connecting hole 23 is defined at the rear of the tail plate 6 , and the end of the second cable 14 is connected to the second connecting hole 23 .

[0029] A clearance hole 24 is formed on the top of the lamp holder 1 , and the first cable 7 passes through the clearance hole 24 .

[0030] A first handle 25 is provided at the end of the first worm 12 , and a second handle 26 is provided at the end of the second worm 19 .

[0031] The working process of the embodiment of the utility model that can realize multi-degree-of-freedom adjustment of the lighting lamp is as follows: the lamp holder 1 is installed at a high position through the first mounting hole 20, and the operating frame 2 is installed at a low position below the lamp holder 1 through the second mounting hole 21;

[0032] In the initial state, under the pulling action of the first spring 5 and the second spring 13, the tail plate 6 of the lighting lamp body 4 is in a direction close to the second spring 13, and at the same time, it is also in a lower limit position in terms of pitch angle;

[0033] When the pitch angle of the lighting lamp body 4 needs to be adjusted, the operator can hold the first handle 25 and drive the first worm 12 to rotate. When the first worm 12 rotates, the first worm gear 11 engaged therewith drives the first drive shaft 10 to rotate, thereby performing a winding or unwinding action on the first cable 7. When the first drive shaft 10 winds up the first cable 7, the first cable 7 pulls the tail plate 6, and the lighting lamp body 4 swings upward with the connection axis with the U-shaped frame 3 as the axis, and the first spring 5 is stretched; when callback is needed, the first drive shaft 10 is driven to unwind the first cable 7. Under the contraction action of the first spring 5, the lighting lamp body 4 swings downward with the connection axis with the U-shaped frame 3 as the axis. In other words, the pitch action of the lighting lamp body 4 can be adjusted by operating the first handle 25.

[0034] When the lighting body 4 needs to be adjusted to swing left and right, the operator can hold the second handle 26 and drive the second worm 19 to rotate. When the second worm 19 rotates, the second worm gear 18 engaged therewith drives the second drive shaft 17 to rotate, thereby winding or unwinding the second cable 14. When the second drive shaft 17 winds up the second cable 14, the second cable 14 pulls the tail plate 6 in the horizontal direction, driving the U-shaped frame 3 as a whole (together with the lighting body 4 thereon) to rotate in one direction, and the second spring 13 is stretched. When callback is required, the second drive shaft 17 is driven to unwind the second cable 14. Under the contraction action of the second spring 13, the U-shaped frame 3 as a whole (together with the lighting body 4 thereon) rotates in the other direction. That is to say, by operating the second handle 26, the lighting body 4 can be adjusted to swing left and right.

[0035] In actual work, the operator can adjust the lighting lamp body 4 in the pitch direction and the left and right swing direction by coordinating the first handle 25 and the second handle 26 .
