When the limiting plug 24 is moved to be inserted into the limiting slot, the position of the plug-in block 12 in the plug-in slot 11 is limited, and the lamp holder 13 is limited in the outer box body 10.

[0050] As shown in Figure 6 and Figure 7 , the bottom end of the limiting plug 24 is fixedly provided with a dovetail block 25, the dovetail block 25 is movably arranged in the dovetail groove 26 on one side of the sliding seat 23, and the push block 21 is fixedly arranged at the top end of the limiting plug 24; the inner side of the limiting plug 24 is fixedly provided with a reset spring 27, one end of the reset spring 27 is fixedly connected with the inner side wall of the sliding plate 22.

[0051] Specifically, when the two opposite push blocks 21 are pushed outward, the two limiting plugs 24 are pushed to move until the limiting plug 24 is moved out of the limiting slot, so that one of the lamp holders 13 can be disassembled. Through the cooperation of the dovetail block 25 and the dovetail groove 26, the sliding connection between the limiting plug 24 and the sliding seat 23 can be achieved.

[0052] As shown in Figure 4 and Figure 6 , the screw plug-in assembly 20 further comprises a screw rod 28 which is threadedly connected with the outer box body 10 and transversely arranged in the working groove, the outer portions of the two ends of the screw rod 28 are provided with threads with opposite rotation directions, and the two ends of the screw rod 28 are respectively threadedly connected with push blocks 29, one side of the push block 29 is provided with an inclined surface 210, and the other side is in close contact with the inner wall of the working groove; the outer side of the sliding plate 22 is fixedly provided with two rolling wheels 211 with wheel seats, when the limiting plug 24 is inserted into the limiting slot, the two rolling wheels 211 respectively contact the inclined surfaces 210 on the two push blocks 29.

[0053] It should be noted that the screw rod 28 is rotated, the rotation of the screw rod 28 can drive the two push blocks 29 connected with the screw rod 29 to move relatively or oppositely, when the two push blocks 29 move relatively, the inclined surface 210 contacts the rolling wheel 211 and pushes the rolling wheel 211 to move, the movement of the rolling wheel 211 drives the sliding plate 22 to move, the movement of the sliding plate 22 drives the sliding seat 23 and the limiting plug 24 to move until the limiting plug 24 is moved to be inserted into the limiting slot, when the two push blocks 29 move oppositely, the push block 29 gradually removes the pushing force on the rolling wheel 211, at this time, through the elastic action of the reset spring 27, the sliding plate 22 can be restored to the original position.

[0054] As shown in Figure 8 and Figure 9As shown, the vertical adjusting assembly 30 includes two limiting sliding seats 31 arranged vertically and fixedly connected with the inner wall of the outer box body 10, the limiting sliding seat 31 is in sliding connection with the heat insulation plate 15, and the top of the limiting sliding seat 31 is provided with a connecting cross seat 32 in the transverse direction, the bottom end of the connecting cross seat 32 is fixedly provided with a tension spring 33, the bottom end of the tension spring 33 is fixedly connected with the heat insulation plate 15; an eccentric wheel 34 is arranged on the top of the heat insulation plate 15 between the two limiting sliding seats 31, a servo motor 37 for driving the eccentric wheel 34 is arranged on the outer wall of the outer box body 10, a limiting wheel groove 35 is formed in the outer side wall of the eccentric wheel 34, a limiting roller 36 is arranged at the bottom of the limiting wheel groove 35 in a limiting manner, and the bottom of the limiting roller 36 is fixedly connected with the heat insulation plate 15.

[0055] In detail, the work of the servo motor 37 can drive the eccentric wheel 34 to rotate half a cycle, and during the half-cycle rotation process, the eccentric wheel 34 will give the limiting roller 36 a pushing force to push the limiting roller 36 to move downward, and the movement of the limiting roller 36 will drive the heat insulation plate 15 to slide downward along the limiting sliding seat 31, and at this time, the movement of the heat insulation plate 15 will drive the heat conduction assembly 40 to move downward, so that the heat conduction assembly 40 can be in closer contact with the lamp holder 13, and the heat dissipation effect of the lamp holder 13 is improved.

[0056] Further, when the heat insulation plate 15 moves downward, the tension spring 33 is in a tension state, and then when the servo motor 37 continues to rotate the eccentric wheel 34 half a cycle and gradually removes the pushing force on the limiting roller 36, the elastic action of the tension spring 33 can make the heat insulation plate 15 return to the original position.

[0057] As shown in Figure 10 and Figure 11 As shown, the heat conduction assembly 40 includes an outer cylinder 41 and an inner cylinder 42 slidably arranged in the outer cylinder 41 and having an open top end, a fixed pad 43 fixedly arranged on the outer wall of the top of the inner cylinder 42 and in sliding connection with the outer cylinder 41, a compression spring 44 sleeved on the outer portion of the inner cylinder 42 at the top end of the fixed pad 43, and the two ends of the compression spring 44 are fixedly connected with the fixed pad 43 and the top wall of the inner cavity of the outer cylinder 41 respectively; a plurality of air permeable holes 45 are formed in the outer wall of the inner cylinder 42 at the bottom of the outer cylinder 41, an outer thread 46 is arranged on the bottom outer wall of the outer cylinder 41 and in threaded connection with the heat insulation plate 15, and a plurality of strip-shaped heat dissipation grooves 47 are equidistantly formed in the top wall of the outer wall of the outer cylinder 41 in the circumferential direction.

[0058] Specifically, when the heat insulation plate 15 moves downward, the heat conduction assembly 40 moves downward, and the bottom of the inner cylinder 42 is in close contact with the top wall of the lamp holder 13 under the elastic action of the abutting spring 44. The close contact between the inner cylinder 42 and the lamp holder 13 can improve the heat conduction effect of the lamp holder 13. The heat is conducted to the outer cylinder 41, and the heat conducted to the outer cylinder 41 is separated from the lamp holder 13 by the heat insulation effect of the heat insulation plate 15. Even if the heat conducted to the outer cylinder 41 is not dissipated in time, it will not affect the operation of the LED lamp bead 14.

[0059] In detail, when the heat dissipation fan 16 works, the heat around the lamp holder 13 can be quickly sucked to the top of the heat insulation plate 15 along the air holes 45 and the heat dissipation grooves 47, and then dissipated. The heat conduction of the inner cylinder 42 and the outer cylinder 41 can accelerate the heat dissipation effect of the lamp holder 13.

[0060] It should be noted that when the lamp holder 13 is disassembled, the limiting plug 24 is separated from the limiting slot, and the abutting spring 44 can pop the plug-in block 12 out of the plug-in slot 11, so that the lamp holder 13 can be conveniently taken out of the outer box body 10.

[0061] Working principle:

[0062] In actual use, a proper number of lamp holders 13 can be selected to install and splice a LED lamp panel with a suitable area. When the lamp holder 13 is installed, two plug-in blocks 12 are inserted into two corresponding plug-in slots 11. After all the lamp holders 13 are installed, the lead screw 28 is rotated. The rotation of the lead screw 28 can drive the two push blocks 29 connected with the lead screw 28 to move relatively or oppositely. When the two push blocks 29 move relatively, the inclined surface 210 contacts the rolling wheel 211 and pushes the rolling wheel 211 to move. The movement of the rolling wheel 211 drives the sliding plate 22 to move. The movement of the sliding plate 22 drives the sliding seat 23 and the limiting plug 24 to move until the limiting plug 24 is inserted into the limiting slot. At this time, the plurality of lamp holders 13 can be inserted and limited at the same time.

[0063] When it is necessary to replace the damaged lamp holder 13, the two limiting plugs 24 can be moved by pushing the two limiting plugs 24 outward, and the limiting plug 24 is moved out of the limiting slot. At this time, the abutting spring 44 can pop the plug-in block 12 out of the plug-in slot 11, so that the lamp holder 13 can be conveniently taken out of the outer box body 10. In this way, one of the lamp holders 13 can be disassembled individually, which is convenient and fast.

[0064] Through the servo motor 37 work can drive eccentric wheel 34 rotation half week, in half cycle rotation process eccentric wheel 34 will give a limit roller 36 push force push limit roller 36 to move down, limit roller 36 movement will drive heat insulation plate 15 along the limit slide 31 to slide down, now through heat insulation plate 15 movement will drive heat conducting assembly 40 to move down, so can guarantee heat conducting assembly 40 can with lamp holder 13 more closely contact, through the inner tube 42 and lamp holder 13 between closely contact can improve the heat dissipation effect of lamp holder 13, heat conduction to outer cylinder 41 through inner tube 42, now cooperate heat insulation plate 15 heat insulation effect, can with the heat of lamp holder 13 after conduction to outer cylinder 41 is separated, even if the heat of transmission to outer cylinder 41 on without timely dispersion will not affect the work of LED lamp bead 14;

[0065] Through the air hole 45 and the setting of heat dissipation groove 47, when the heat dissipation fan 16 works, the heat around the lamp holder 13 can be quickly sucked into the top of the heat insulation plate 15 along the air hole 45 and the heat dissipation groove 47, and then dispersed, which can accelerate the heat dissipation effect of the lamp holder 13 by cooperating the heat conduction of the inner tube 42 and the outer cylinder 41.

[0066] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the skilled in the art, it still can be modified, or equivalent to replace part of the technical features described in the foregoing embodiments.
