[0022] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0023] As shown in the attached Figure 1 figure, a conveniently installable lamp track bar includes a track main body 1 and a mounting bracket 3.

[0024] As shown in the attached Figure 1 and Figure 2 figure, the cross-section of the track main body 1 is in a "ji" shape. At both ends of the upper surface of the track main body 1, two lifting screws 16 are provided respectively. The lifting screws 16 penetrate through the upper surface of the track main body 1 and are rotatably arranged on the track main body 1. Specifically, at both ends of the upper surface of the track main body 1, two first positioning holes 12 are provided respectively. The first positioning holes 12 correspond to the lifting screws 16 one by one. The lifting screws 16 penetrate through the first positioning holes 12 and are rotatably arranged in the first positioning holes 12. On both sides of the upper surface of the track main body 1, vertical support plates 14 are symmetrically provided. A number of limiting holes 15 are provided at both ends of the vertical support plates 14. At the same time, four mounting brackets 3 are provided on the track main body 1. The four mounting brackets 3 correspond to the four lifting screws 16 one by one, and the four mounting brackets 3 are respectively arranged corresponding to the two vertical support plates 14.

[0025] Among them, as shown in the attached Figures 4 to 7 figure, the mounting bracket 3 includes a limiting part 31, a lifting part 32, a torsion spring 33 and a rotating shaft 34. The limiting part 31 includes a fixing piece 311 and a limiting hook 312 arranged on the fixing piece 311. The lifting part 32 includes a lifting plate 321, a connecting plate 322, a connecting arm 323 and a threaded sleeve 324. The lifting plate 321 and the connecting plate 322 are connected end to end to form an obtuse angle. Connecting arms 323 are provided on both sides of the connecting plate 322. A threaded sleeve 324 is provided on the lifting plate 321. The fixing piece 311 of the limiting part 31 and the connecting arm 323 of the lifting part 32 are both hinged to the rotating shaft 34. The torsion spring 33 is movably sleeved outside the rotating shaft 34, and the supporting feet 331 at both ends of the torsion spring 33 respectively abut against the surface of the fixing piece 311 and the surface of the connecting plate 322. The threaded sleeve 324 of the lifting part 32 is threadedly connected to the lifting screw 16, and the fixing piece 311 of the limiting part 31 is movably located on the vertical support plate 14. As shown in the attached Figure 7 and Figure 8As shown, when in use, by rotating the lifting screw 16, the lifting part 32 drives the limiting part 31 to be lifted above the track body 1. During the process, due to the obstruction and restriction of the fixing piece 311 of the limiting part 31 by the vertical support plate 14, the fixing piece 311 is located on the vertical support plate 14 and flexibly twists the torsion spring 33. With the twisting force storage of the torsion spring 33, the limiting parts 31 on the four mounting frames 3 can be located on both sides of the track body 1 and rotate outward or rotate inward. At the same time, during the lifting and lowering process of the lifting part 32, the limiting hook 312 of the limiting part 31 can be flexibly hooked into the limiting hole 15. The limiting hook 312 is limited by the inner wall of the limiting hole 15, so as to prevent the limiting part 31 from detaching from the vertical support plate 14 during the rotation and expansion process.

[0026] It is worth mentioning that Figure 3 , Figure 5 and Figure 6 As shown, guide notches 325 are provided on both sides of the lifting plate 321, and a plurality of guide light rods 24 are provided on the upper surface of the track body 1, and the guide light rods 24 are matched with the guide notches 325, and the guide light rods 24 are grouped in pairs, and each group of guide light rods 24 corresponds to a lifting screw 16, and when the lifting plate 321 is lifted and lowered along the lifting screw 16, the two guide notches 325 on the lifting plate 321 are respectively sleeved on the outer sides of the two guide light rods 24 of each group to be lifted and lowered. The outer surface of the guide light rod 24 guides the inner wall of the guide notch 325, so as to prevent the lifting plate 321 from rotating along with the lifting screw 16, on the one hand, ensuring that the lifting plate 321 can be lifted and lowered smoothly and stably, and on the other hand, ensuring that the limit hook 312 of the limit part 31 can be smoothly hooked into the limit hole 15 on the vertical support plate 14.

[0027] Specifically, as attached Figure 3 , Figure 5 and Figure 6As shown, a connecting frame 2 is provided at each end of the upper surface of the track body 1, and a connecting piece 21 is provided at each end of the connecting frame 2. The connecting piece 21 is provided with a third positioning hole, and two second positioning holes 13 are provided at each end of the upper surface of the track body 1. The second positioning holes 13 correspond to the third positioning holes one by one. When the connecting frame 2 is placed on the upper surface of the track body 1, the second positioning holes 13 are aligned with the third positioning holes, and the fixing screws 22 pass through the third positioning holes and are threadedly connected with the second positioning holes 13. The connecting frame 2 is fixed to the upper surface of the track body 1 by the fixing screws 22, and four guide light rods 24 are provided on the connecting frame 2. At this time, since the connecting frame 2 is arranged across the lifting screw 16, a through hole 23 is required to be provided on the connecting frame 2. The through hole 23 corresponds to the lifting screw 16, and the diameter of the through hole 23 is larger than the diameter of the screw rod of the lifting screw 16. The lifting screw 16 passes through the through hole 23, and the lifting screw 16 is located in the through hole 23 and rotates. By providing the through hole 23 , the connection frame 2 is prevented from affecting and hindering the rotation of the lifting screw 16 , thereby ensuring the lifting and use of the mounting frame 3 .

[0028] In summary, during installation, the present invention first places the top of the track body 1 into the notch 41 of the ceiling 4 until the horizontal support plates 11 on both sides of the bottom of the track body 1 are against the bottom surface of the ceiling 4. At this time, the mounting bracket 3 on the track body 1 passes through the notch 41 and is located above the ceiling 4. Then the operator uses a screwdriver or other tool to rotate the lifting screw 16 in the track body 1. Since the lifting part 32 is threadedly connected with the lifting screw 16, the lifting part 32 drives the limiting part 31 located above the track body 1 to descend. During the process, the vertical support plate 14 will block and restrict the limiting part 31, so that the limiting part 31 is located on the vertical support plate 14 and moves, rotates outward, and twists the torsion spring 33, so that the limiting parts 31 on the four mounting brackets 3 can be located on both sides of the track body 1 and rotated outward, and are suspended above the ceiling 4. Finally, the track body 1 is released, and the track body 1 falls under the action of its own gravity until the limiting part 31 on the track body 1 is supported on the upper surface of the ceiling to complete the installation of the track bar. And because each mounting bracket 3 is driven by a separate lifting screw 16, the mounting bracket 3 can be adjusted individually according to the thickness of the ceiling, so that the track bar can be adapted to ceilings of different thicknesses, and the track bar can be fixed even if the thickness of the ceilings on both sides is different. At the same time, during the descent of the lifting part 32, the limiting hook 312 of the limiting part 31 can be movably hooked into the limiting hole 15. The limiting effect of the limiting hook 312 on the inner wall of the limiting hole 15 can prevent the limiting part 31 from being separated from the vertical support plate 14 during the rotation and expansion process, and play a role in limiting and preventing pulling, so that the track bar will not be forcibly torn off after installation. When it is necessary to remove the track bar, the above steps can be reversed to remove the track body 1 from the notch 41 together with the mounting bracket 3. The operation is convenient, the track bar can be quickly removed, and the ceiling will not be damaged when the track bar is fixed. Among them, the lifting screws 16 and the mounting bracket 3 are both set to an even number, so that the mounting bracket 3 can be evenly distributed to both sides of the track body 1, so that the installation of the track bar is more balanced.

[0029] An installation procedure for a conveniently installed lamp track strip is characterized by being performed in the following steps: The first step is to place the top of the track body 1 into the notch 41 of the ceiling 4 until the transverse support plates 11 on both sides of the bottom of the track body 1 abut against the bottom surface of the ceiling 4. At this time, the mounting frame 3 on the track body 1 passes through the notch 41 and is located above the ceiling 4. In the second step, the operator uses a tool such as a screwdriver to turn the lifting screw 16 in the track body 1; In the third step, the lifting part 32 drives the limiting part 31 located above the track body 1 to descend. During the process, the vertical support plate 14 will block and restrict the limiting part 31, so that the limiting part 31 is movable on the vertical support plate 14 and rotates outward, twisting the torsion spring 33, so that the limiting parts 31 on the four mounting frames 3 can be located on both sides of the track body 1 and rotate outward, and be suspended above the ceiling 4; In the fourth step, the track body 1 is released, and the track body 1 falls under its own gravity until the limiting portion 31 on the track body 1 is supported on the upper surface of the ceiling, so as to complete the installation of the track bar.

[0030] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
