Specifically, when the lamp is installed, fixing points are manufactured in advance on the lamp, the fixing device is installed on a wall, and then the lamp is installed on the fixing device. For some ceiling lamps with larger volume, the ceiling lamps are similar to rectangular ceiling lamps in classrooms, and generally more than two stress points are needed to ensure the stability of the lamp. Thus, it is required that the fixing device is installed accurately enough to correspond to the position of the stress point on the lamp, or the lamp cannot be fixed. Under some circumstances, adopt fixed ceiling lamp of this kind of material of rope, it is more convenient to install like this, and the fault-tolerant rate is high, does not need very high installation accuracy. However, the lamp is not stable, easy to shake and unsafe, and the light shaking causes damage to eyes. The device fixes the lamp through the installation suspender 3, so that the lamp is high in stability and cannot shake. The fixture block 510 is matched with the sliding groove 21, so that the fault tolerance rate of lamp installation is higher, the hanger rod 3 is fixed more simply, and the installation is not required to be accurate. Sliding support 2 with set up between the installation jib 3 installation vaulting pole 5 will fixture block 510 inserts in the spout 21, just can be simple fixed sliding support 2 with installation vaulting pole 5 adopts the mode of bolt to fix installation jib 3 with installation vaulting pole 5 just can make lighting fixture 1 with installation jib 3 is connected. At this time, the lamp holder 1 is kept still by the tensile force of the mounting hanger 3, and the installer does not need to hold the lamp holder 1 all the time. The stress point of the lamp is roughly fixed, so that the lamp is suspended in the air under the pulling force of the mounting suspension rod 3, then the rest stress point of the lamp is fixed, the fixed position is adjusted, and the lamp can be mounted by only one person.

The sliding support 2 is fixed on the lamp holder 1 through a screw 8, and is convenient to detach and replace. It should be further noted that other components may be employed to achieve the above-mentioned effects, which are within the inventive concept of the present invention and are within the scope of the present invention.

An electrical box 4 used for protecting a power supply is fixed on the lamp holder 1, and the electrical box 4 is provided with a sealing ring to prevent dust and the like from entering the power supply and prolong the service life of the power supply.

Referring to fig. 3, the lamp further includes a rubber ring 9, a protective cover 10, a fixing frame 11 and a second latch rod 12, the fixing frame 11 is fixed on a top wall, a hollow protrusion 111 is downward arranged at the center of the fixing frame 11, through holes matched with the shape of the mounting hanger rod 3 are formed in the rubber ring 9, the protective cover 10 and the protrusion 111, and an upper latch hole 320 matched with the second latch rod 12 is formed at the top end of the mounting hanger rod 3. Specifically, the fixing frame 11 is fixed on a top wall, and the installation hanging rod 3 is fixed on the fixing frame 11 through the second bolt rod 12, so that the installation and the disassembly are convenient. The protective cover 10 and the top wall form a closed space, surround the joint of the fixed frame 11 and the mounting hanger rod 3, and form certain protection while being attractive. The rubber ring 9 is used for fixing the protective cover 10 and preventing the protective cover from sliding downwards.

Referring to fig. 4, the mounting suspension rod 3 is a hollow round rod, and vertically recessed notches 330 are formed at the top end and the bottom end of the mounting suspension rod 3. The installation suspender 3 and the installation stay bar 5, and the installation suspender 3 and the fixing frame 11 are all fixed in a mode of sleeving and inserting a bolt, the calibers of different structures at the joint are different, and the calibers are small and are inserted into holes with large calibers. The aperture difference is large, and the small aperture can move back and forth unstably; the aperture difference is small, and the installation is inconvenient. The notch 330 is arranged, so that the installation suspender 3 can deform to a certain extent under stress, and the lamp can be conveniently installed.

Referring to fig. 5, the lamp further includes a light source assembly 13, a diffusion plate 14, and an antiglare shield 15 sequentially disposed below the lamp holder 1, and the lamp holder 1 and the antiglare shield 15 are fixed by plastic rivets. The anti-dazzle plate 15 effectively reduces the dazzle value of lamplight, protects human eyes, reduces the myopia rate, and the lamp bracket 1 and the anti-dazzle plate 15 are fixed by plastic rivets to prevent glue from falling off and improve the structural stability of the lamp.

The working principle is as follows: and installing the lamp holder 1, the light source assembly 13, the diffusion plate 14 and the antiglare shield 15, and fixing the electrical box 4 and the sliding support 2.

The fixing frame 11 is fixed on a top wall, the top end of the mounting suspension rod 3 sequentially penetrates through the rubber ring 9, the protective cover 10 and the through hole of the boss 111, the second bolt rod 12 is mounted, and the protective cover 10 and the rubber ring 9 are pushed upwards. The latch 510 is inserted into the slide groove 21, the nut 6 is tightened, the lamp is lifted up, the lower latch hole 310 and the first latch hole 522 are aligned, and the first latch rod 7 is installed. And repeating the steps, and installing the fixing frame 11 and other devices at the other end.

After the installation is finished, the position of the lamp is adjusted through the fixture block 510 and the sliding groove 21, and after the adjustment is finished, the nut 6 is screwed down.

While embodiments of the utility model have been disclosed above, it is not limited to the applications set forth in the specification and the embodiments, which are fully applicable to various fields of endeavor for which the utility model pertains, and further modifications may readily be made by those skilled in the art, it being understood that the utility model is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
