[0047] In specific implementation:

[0048] First, install the LED lamp body 3 at a suitable position by means of the mounting cover plate 41, the LED lamp body 3 is initially in a forward irradiation angle, the cross support frame 2 and the LED lamp body 3 are initially in a magnetic attraction connection state, and the T-shaped magnetic attraction rod one 43 and the T-shaped magnetic attraction rod two 44 are aligned and also in a magnetic attraction connection state.

[0049] When it is necessary to adjust the LED lamp body 3 to a transverse irradiation angle, first intermittently rotate the annular matching plate 51 by 45 degrees by the worker to drive the annular contact plate 52, until the plurality of contact structures at the lower end of the annular contact plate 52 are rotated to positions of the plurality of circular through holes outside the transverse direction, during which the annular contact plate 52 will respectively extrude the corresponding T-shaped baffle 62, so that it slides downward along the annular sliding groove and blocks the corresponding circular through hole, and every time the annular matching plate 51 is intermittently rotated by 45 degrees, the plurality of arc-shaped magnets 53 on the annular matching plate 51 will be intermittently magnetically attracted or separated from the plurality of arc-shaped magnets 53 on the annular cover plate 1, to assist the worker to conveniently adjust the angle.

[0050] Then, the LED lamp body 3 is rotated by 90 degrees, so that the T-shaped magnetic rod one 43 and the T-shaped magnetic rod two 44 become staggered to reduce the magnetic attraction, and under the magnetic connection of the cross support frame 2 and the LED lamp body 3, the cross support frame 2 is continuously pulled out by the LED lamp body 3 away from the mounting cover plate 41, during which the plurality of support alignment rods 631 will slide along the cavities formed between the adjacent two arc-shaped limiting plates 61, until the plurality of support alignment rods 631 are moved to the position where they are flush with the plurality of circular through holes, at this time, because the plurality of circular through holes except the transverse direction are blocked by the corresponding T-shaped baffle 62, only the two transverse support alignment rods 631 extend into the corresponding stepped sliding grooves under the action of the compression spring, and are inserted into the corresponding circular through holes, during which the plurality of wedge-shaped clamping plates 731 will first be extruded by the corresponding support alignment rods 631 and retreat into the corresponding containing sliding grooves, then pop out of the corresponding containing sliding grooves and insert into the corresponding clamping grooves, so that the two transverse annular columns 71 and the corresponding support alignment rods 631 are clamped, then the staff simultaneously press the two transverse annular cover plates 732 to make the corresponding toothed rings 741 approach each other, until the two transverse toothed rings 741 are separated from the corresponding limiting clamping plates 742 to release the limiting action on the toothed rings 741.

[0051] The staff can simultaneously rotate the two transverse annular cover plates 732 in the desired adjustment direction, and drive the corresponding support alignment rods 631 to rotate synchronously through the two transverse annular columns 71, the two transverse support alignment rods 631 will jointly drive the LED lamp body 3 to rotate to the desired illumination angle through the cross support frame 2, finally the staff releases the pressing on the two transverse annular cover plates 732, and under the action of the compression spring, the two transverse toothed rings 741 return to their original positions and again align with the corresponding limiting clamping plates 742 to restore the limiting action on the toothed rings 741, it should be noted that the plurality of limiting clamping plates 742 are initially aligned with the corresponding toothed rings 741 to limit the action, and during the rotation of the cross support frame 2 driven by the LED lamp body 3 to the desired illumination angle, the cross support frame 2 will extrude the T-shaped magnetic rod one 43 to retreat into the hollow column 42, when the cross support frame 2 is reset subsequently, under the action of the compression spring, the cross support frame 2 will extend out of the hollow column 42 to return to its original position, and the other two support alignment rods 631 will rotate around the two transverse support alignment rods 631 along the inner wall of the annular structure of the annular matching plate 51 and the inner wall of the annular cover plate 1, and the plurality of abutting sliding plates 54 adjacent to the rotation angle of the LED lamp body 3 will be extruded and retreat into the corresponding mounting sliding grooves.

[0052] When the LED lamp body 3 needs to be adjusted in the vertical illumination angle, the annular abutting plate 52 is intermittently rotated by 45 degrees by the staff through the annular matching plate 51, until the multiple abutting structures at the lower end of the annular abutting plate 52 are respectively rotated to the positions of multiple circular through holes outside the vertical direction, during which the annular abutting plate 52 will respectively extrude the corresponding T-shaped baffle 62, so that it slides downward along the annular sliding groove and blocks the corresponding circular through hole. Then the above-mentioned horizontal illumination angle adjustment steps are repeated, the difference being that after the multiple support alignment rods 631 are moved to the positions flush with the multiple circular through holes, at this time, since the multiple circular through holes outside the vertical direction are all blocked by the corresponding T-shaped baffles 62, only the two vertical support alignment rods 631 extend out of the corresponding stepped sliding grooves and are inserted into the corresponding circular through holes under the action of the compression spring. Finally, the two vertical annular sleeve plates 732 are simultaneously rotated in the desired adjustment direction by the staff, and the corresponding support alignment rods 631 are synchronously rotated by the two vertical annular columns 71. The two vertical support alignment rods 631 will jointly rotate the LED lamp body 3 to the desired illumination angle through the cross support frame 2.

[0053] When the LED lamp body 3 needs to be adjusted in the vertical illumination angle, the annular abutting plate 52 is intermittently rotated by 45 degrees by the staff through the annular matching plate 51, until the multiple abutting structures at the lower end of the annular abutting plate 52 are respectively rotated to the positions of multiple circular through holes outside the vertical direction, during which the annular abutting plate 52 will respectively extrude the corresponding T-shaped baffle 62, so that it slides downward along the annular sliding groove and blocks the corresponding circular through hole. Then the above-mentioned horizontal illumination angle adjustment steps are repeated, the difference being that after the multiple support alignment rods 631 are moved to the positions flush with the multiple circular through holes, at this time, since the multiple circular through holes outside the vertical direction are all blocked by the corresponding T-shaped baffles 62, only the two vertical support alignment rods 631 extend out of the corresponding stepped sliding grooves and are inserted into the corresponding circular through holes under the action of the compression spring. Finally, the two vertical annular sleeve plates 732 are simultaneously rotated in the desired adjustment direction by the staff, and the corresponding support alignment rods 631 are synchronously rotated by the two vertical annular columns 71. The two vertical support alignment rods 631 will jointly rotate the LED lamp body 3 to the desired illumination angle through the cross support frame 2.

[0054] When it is necessary to reset the irradiation angle of the LED lamp body 3 to be forward, according to the current orientation direction of the LED lamp body 3, the reverse operation corresponding to the above-mentioned irradiation angle adjusting step is selected, the corresponding two annular sleeve plates 732 are pressed by the staff at the same time to release the limiting effect of the limiting clamping plate 742 on the tooth ring 741, under the action of the compression spring, the plurality of abutting sliding plates 54 installed in the sliding groove will extend out of the sliding groove to restore the original position, thereby pushing the LED lamp body 3 to the center position of the annular cover plate 1 to restore the forward irradiation angle, then the corresponding two pressing rods 733 are pressed by the staff, the corresponding supporting alignment rods 631 are respectively pushed by the corresponding two pressing rods 733, so as to retreat into the corresponding stepped sliding groove, and the cross support frame 2 is further rotated by the LED lamp body 3, until the T-shaped magnetic rod one 43 and the T-shaped magnetic rod two 44 are aligned, and at this time, the plurality of supporting alignment rods 631 correspond to the cavities formed between every two adjacent arc-shaped limiting plates 61, then the T-shaped magnetic rod one 43 and the T-shaped magnetic rod two 44 are restored to be magnetically connected by pressing the LED lamp body 3.

[0055] When the LED lamp body 3 needs to be disassembled and replaced, the two plug-in rods 45 are pressed by the staff at the same time, so as to be respectively inserted into the corresponding plug-in grooves, thereby realizing the connection of the annular cover plate 1 and the cross support frame 2, then the LED lamp body 3 is pulled away from the mounting cover plate 41 by the staff, so that the LED lamp body 3 and the cross support frame 2 are disconnected, and the replacement of the LED lamp body 3 can be realized.

[0056] In summary, the application has the following advantages:

[0057] Advantage one, the cross support frame 2, the LED lamp body 3 and the mounting cover plate 41 in the application adopt magnetic quick connection, the two plug-in rods 45 are pressed by the staff at the same time, so as to be respectively inserted into the corresponding plug-in grooves, thereby realizing the connection of the annular cover plate 1 and the cross support frame 2, then the LED lamp body 3 is pulled away from the mounting cover plate 41 by the staff, so that the LED lamp body 3 and the cross support frame 2 are disconnected, and the replacement of the LED lamp body 3 can be realized.

[0058] The second advantage is that the staff drives the annular abutment plate 52 to rotate intermittently by 45 degrees through the annular matching plate 51, until the multiple abutting structures at the lower end of the annular abutment plate 52 are respectively rotated to the positions of multiple circular through holes other than the horizontal or vertical direction, so that the T-shaped baffle 62 slides downward along the annular sliding groove and blocks the corresponding circular through hole. The cross support frame 2 is synchronously rotated by rotating the LED lamp body 3. When the multiple support alignment rods 631 are moved to the positions flush with the multiple circular through holes, they are respectively inserted into the corresponding circular through holes that are not blocked. Then the staff rotates the two annular sleeve plates 732 in the vertical direction simultaneously in the desired adjustment direction, and the corresponding support alignment rods 631 are synchronously rotated by the two annular columns 71 in the horizontal or vertical direction. The two support alignment rods 631 in the horizontal or vertical direction will jointly rotate the LED lamp body 3 to the desired illumination angle through the cross support frame 2, so as to flexibly adjust the illumination angle of the LED lamp body 3 around the horizontal or vertical direction according to the use scene.

[0059] The third advantage is that the staff drives the annular abutment plate 52 to rotate intermittently by 45 degrees through the annular matching plate 51, until the multiple abutting structures at the lower end of the annular abutment plate 52 are respectively rotated to the positions of multiple circular through holes other than the desired diagonal direction, so that the T-shaped baffle 62 slides downward along the annular sliding groove and blocks the corresponding circular through hole. When the multiple support alignment rods 631 are moved to the positions flush with the multiple circular through holes, the staff rotates the cross support frame 2 in the desired diagonal direction by 45 degrees through the LED lamp body 3. Two support alignment rods 631 will be inserted into the corresponding circular through holes that are not blocked. Then the staff rotates the two annular sleeve plates 732 in the desired diagonal direction simultaneously in the desired adjustment direction, and the corresponding support alignment rods 631 are synchronously rotated by the two annular columns 71 in the desired diagonal direction. The two support alignment rods 631 in the desired diagonal direction will jointly rotate the LED lamp body 3 to the desired illumination angle through the cross support frame 2, so as to flexibly adjust the illumination angle of the LED lamp body 3 around the diagonal direction according to the use scene.

[0060] The fourth advantage is that when the staff simultaneously press the two annular sleeve plates 732 to drive the corresponding toothed rings 741 to approach each other until the two toothed rings 741 are respectively disengaged from the corresponding limiting clamping plates 742 to release the limiting effect on the toothed rings 741, the two annular sleeve plates 732 can be simultaneously rotated in the desired adjustment direction, and the corresponding support alignment rods 631 are driven to rotate synchronously by the two annular columns 71, and the two support alignment rods 631 will jointly drive the LED lamp body 3 to rotate to the desired illumination angle by the cross support frame 2. When the staff releases the press on the two annular sleeve plates 732, the two toothed rings 741 return to the original position and are flush with the corresponding limiting clamping plates 742 again to restore the limiting effect on the toothed rings 741, so that the effect of locking and limiting after adjusting the illumination angle of the LED lamp body 3 is realized, the problems of loosening after multiple adjustments of the LED lamp body 3 and the problem of illumination angle deviation due to the change of the center of gravity of the LED lamp body 3 when adjusted to some angles are avoided, and the stability of the LED lamp body 3 after adjusting the illumination angle is effectively improved.

[0061] The fifth advantage is that when adjusting the illumination angle, the two support alignment rods 631 are inserted into the corresponding circular through holes, and under the action of the compression spring, the other two support alignment rods 631 will rotate around the two support alignment rods 631 inserted into the circular through holes along the inner wall of the annular structure of the annular matching plate 51 and the inner wall of the annular cover plate 1, and after the LED lamp body 3 is adjusted to the desired illumination angle and is locked and limited, the other two support alignment rods 631 will be in close contact with the inner wall of the annular structure of the annular matching plate 51 and the inner wall of the annular cover plate 1 to achieve the effect of tensioning, and the stability of the LED lamp body 3 after adjusting the illumination angle can be further improved by the cross distribution structure.

[0062] The sixth advantage is that when adjusting the illumination angle, the plurality of abutting sliding plates 54 adjacent to the desired illumination angle of the LED lamp body 3 will be pressed back into the corresponding mounting sliding groove, and when reset, under the action of the compression spring, the plurality of abutting sliding plates 54 retreated into the mounting sliding groove will extend out of the mounting sliding groove to return to the original position, thereby achieving the effect of assisting in pushing the LED lamp body 3 to approach the center position of the annular cover plate 1 and restoring the forward illumination angle.
