Specifically, the limiting member 23 can be a latch, the fixing hole 211 is aligned with different limiting holes 221, and the limiting member 23 passes through the fixing hole 211 and the limiting hole 221 at the same time, so that the height of the support assembly 2 can be adjusted according to the height of the pre-installed frame 1 and the thickness of the ceiling 101.

[0029] In this embodiment, two fixing holes 211 are provided, and the two fixing holes 211 are flush in the horizontal direction and are both arranged close to the second support tube 22; two rows of limiting holes 221 are provided, and the two rows of limiting holes 221 are arranged staggered with each other in the horizontal direction. Such an arrangement enables the support assembly 2 to adapt to more thicknesses of the ceiling 101. The first support tube 21 and the second support tube 22 are inseparable. Specifically, the first support tube 21 is provided with a first stopper 212 at one end facing the second support tube 22, and the second support tube 22 is provided with a second stopper 222 at one end facing the first support tube 21. The first stopper 212 extends inwardly, and the second stopper 222 extends outwardly. The second stopper 222 is engaged with the first stopper 212 to limit the second support tube 22 from being separated from the first support tube 21.

[0030] The support components 2 are provided with at least two groups and are evenly distributed on the outside of the pre-installed frame 1. The lamp pre-installed frame fixing structure 100 is not limited by the shape of the pre-installed frame 1, that is, the lamp pre-installed frame fixing structure 100 is applicable to lamps of various shapes. In this embodiment, the support components 2 are provided with three groups, corresponding to the three operation holes 11, which further ensures the installation stability of the pre-installed frame 1, and is safe and reliable after installation without the possibility of falling.

[0031] The end of the second support tube 22 is provided with a mounting seat 223, and the mounting seat 223 is in contact with the ceiling 101. The mounting seat 223 can be moved on the ceiling 101 so that the support assembly 2 is vertically connected between the pre-installed frame 1 and the ceiling 101. The end of the first support tube 21 is provided with a fixing plate 213, and the fixing plate 213 extends toward the pre-installed frame 1 and is overlapped and fixed at the edge of the pre-installed frame 1. The end of the pre-installed frame 1 corresponding to the first support tube 21 is provided with a connecting portion 12, and the connecting portion 12 extends inward from the inner edge of the pre-installed frame 1 and is fixedly connected to the fixing plate 213.

[0032] The fixing plate 213 is provided with a connection hole 214, and the connecting portion 12 is correspondingly provided with a matching hole 121. The connection hole 214 is aligned with the matching hole 121 for the fastener 3 to be inserted to fix the fixing plate 213 and the connecting portion 12. The fastener 3 includes a bolt 31 and a nut 32. The bolt 31 is inserted into the connection hole 214 from the matching hole 121. The nut 32 is located on the side of the fixing plate 213 away from the connecting portion 12 and is tightened on the bolt 31. When the support assembly 2 is at the minimum height, the fixing plate 213 and the connecting portion 12 are pre-connected by the fastener 3, that is, when the nut 32 is not tightened, the support assembly 2 is connected to the pre-installed frame 1 to limit each other; when the lower surface of the pre-installed frame 1 is flush with the ceiling 101 and fixed, the limiting member 23 is simultaneously passed through the fixing hole 211 and the limiting hole 221 of the corresponding height, and the fastener 3 is tightened.

[0033] The end of the pre-installed frame 1 close to the second support tube 22 is provided with an abutment portion 13, which extends outward from the outer edge of the pre-installed frame 1. The abutment portion 13 is located on the side of the ceiling 101 away from the support assembly 2. The abutment portion 13 is provided with a plurality of through holes 131 for screws 4 to pass through to fix the pre-installed frame 1 to the ceiling 101. The ceiling 101 is correspondingly provided with a receiving groove (not shown), and the abutment portion 13 is received in the receiving groove. The abutment portion 13 is flush with the ceiling 101, so that the lower surface of the pre-installed frame 1 is flush with the ceiling 101, thereby improving the aesthetic feeling of home decoration.

[0034] The installation steps of the lamp pre-installed frame fixing structure 100 are specifically as follows: when the ceiling is suspended, a mounting hole 102 of a corresponding size is opened on the ceiling 101 according to the specifications of the pre-installed frame 1, and the support assembly 2 is placed on the ceiling 101 after determining the installation direction of the ceiling 101. Then, when the support assembly 2 is at the minimum height, the pre-installed frame 1 and the support assembly 2 are pre-connected. That is, when the first support tube 21 is completely covered on the second support tube 22, the pre-installed frame 1 and the support assembly 2 are pre-connected through the fastener 3, that is, after the bolt 31 is inserted from the matching hole 121 into the connecting hole 214, the nut 3 is tightened. 2 is screwed on the bolt 31 to put the support assembly 2 and the pre-installed frame 1 in a state of active connection. This is to adjust the distance between the fixing plate 213 of the support assembly 2 and the connecting portion 12 of the pre-installed frame 1 when the fixing hole 211 and the limiting hole 221 are not aligned, so that the fixing hole 211 and the limiting hole 221 are aligned; then the pre-installed frame 1 is fixedly connected to the ceiling 101 by screws 4 to determine the height of the support assembly 2, and then the limiting member 23 is inserted into the fixing hole 211 and the limiting hole 221 at the same time, and finally the fastener 3 is tightened to realize the installation of the lamp pre-installed frame fixing structure 100.

[0035] In summary, the utility model embeds the pre-installed frame 1 into the installation hole 102 of the ceiling 101, and at the same time sets the support assembly 2 on the outside of the pre-installed frame 1 and perpendicular to the ceiling 101, so that the end of the first support tube 21 can be fixedly connected to the pre-installed frame 1, and the end of the second support tube 22 can be abutted against the ceiling 101. At the same time, the height of the support assembly 2 can be adjusted by the up and down sliding cooperation between the first support tube 21 and the second support tube 22.

[0036] In addition, by opening the operation hole 11 on the pre-installed frame 1 corresponding to the support assembly 2, the limiter 23 can be used to simultaneously pass through the fixing hole 211 and the limiter hole 221 to make the lower surface of the pre-installed frame 1 flush with the ceiling 101. Compared with the prior art, the utility model can not only adapt to different thicknesses of the ceiling 101 and directly realize the fixed connection between the pre-installed frame 1 and the ceiling 101, but also is convenient to disassemble and assemble, safe and reliable, makes good use of the ceiling space, and improves the aesthetics of home decoration.
