[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1 and Figure 4 As shown, the utility model discloses a lamp pre-installed frame fixing structure 100, which is embedded and fixed to a ceiling 101. The lamp pre-installed frame fixing structure 100 comprises: a pre-installed frame 1 and a support assembly 2, wherein the pre-installed frame 1 is embedded and installed in a mounting hole 102 of the ceiling 101, and the support assembly 2 is located outside the pre-installed frame 1 and is vertically arranged to the ceiling 101.

[0025] The support assembly 2 includes a first threaded support member 21, a second threaded support member 22, and an adjusting nut 23 connecting the first threaded support member 21 and the second threaded support member 22. The end of the first threaded support member 21 is fixedly connected to the pre-installed frame 1, and the end of the second threaded support member 22 abuts against the ceiling 101. The lamp pre-installed frame fixing structure 100 of the utility model can not only adapt to different ceiling 101 thicknesses, 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.

[0026] like Figure 1-Figure 4 As shown, the support assembly 2 is configured such that when the adjusting nut 23 is adjusted, the first threaded support member 21 and the second threaded support member 22 move in opposite directions, driving the pre-installed frame 1 to rise until the lower surface of the pre-installed frame 1 is flush with the ceiling 101. In other words, 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.

[0027] Specifically, an operation hole 11 is provided on the pre-installed frame 1 at a position corresponding to the adjusting nut 23, and a wrench is used to adjust the adjusting nut 23 through the operation hole 11. The thread teeth on the outside of the first threaded support 21 and the second threaded support 22 are opposite to each other, and the adjusting nut 23 is adapted to the thread teeth on the first threaded support 21 and the second threaded support 22. The length of the adjusting nut 23 is roughly the sum of the lengths of the first threaded support 21 and the second threaded support 22, that is, the adjusting nut 23 can accommodate the first threaded support 21 and the second threaded support 22 inside it at the same time. By adjusting the adjusting nut 23, it can adapt to different thicknesses of the ceiling 101, and the pre-installed frame 1 can be installed and fixed on the ceiling 101.

[0028] 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.

[0029] In this embodiment, a base 221 is provided at one end of the second threaded support member 22 away from the adjusting nut 23, and the base 221 is in contact with the ceiling 101. The base 221 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. A connecting piece 211 is provided at one end of the first threaded support member 21 away from the adjusting nut 23, and the connecting piece 211 extends toward the pre-installed frame 1 and is overlapped and fixed at the edge of the pre-installed frame 1. A connecting portion 12 is provided at one end of the pre-installed frame 1 corresponding to the first threaded support member 21, and the connecting portion 12 extends inward from the inner edge of the pre-installed frame 1, and the connecting piece 211 is fixedly connected to the connecting portion 12.

[0030] The connecting piece 211 is provided with a connecting hole 212, and the connecting portion 12 is correspondingly provided with a matching hole 121. The connecting hole 212 is aligned with the matching hole 121 for the fastener 3 to be inserted, so as to fix the connecting piece 211 with the connecting portion 12. The fastener 3 includes a bolt 31 and a nut 32. The bolt 31 is inserted into the connecting hole 212 from the matching hole 121, and the nut 32 is located on the side of the connecting piece 211 away from the connecting portion 12 and is screwed onto the bolt 31.

[0031] An abutment portion 13 is provided at one end of the pre-installed frame 1 close to the second threaded support member 22. The abutment portion 13 extends outward from the outer edge of the pre-installed frame 1 and is located on the side of the ceiling 101 away from the support assembly 2. A corresponding receiving groove (not shown) is provided on the ceiling 101. The abutment portion 13 is received in the receiving groove so that the lower surface of the pre-installed frame 1 is flush with the ceiling 101, thereby improving the aesthetics of the home decoration. The abutment portion 13 is provided with a through hole 131 for screws (not numbered) to pass through to fix the pre-installed frame 1 to the ceiling 101. In this embodiment, a plurality of through holes 131 are provided, and are evenly arranged around the abutment portion 13.

[0032] 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 corresponding size is opened on the ceiling 101 according to the specifications of the pre-installed frame 1, and the installation direction of the ceiling 101 is determined. The support assembly 2 is first placed on the ceiling 101, and then the pre-installed frame 1 and the support assembly 2 are fixedly connected when the support assembly 2 is at the minimum height. That is, when the first threaded support member 21 and the second threaded support member 22 are both accommodated in the adjusting nut 23, the connecting piece 211 of the first threaded support member 21 is tightened with the connecting portion 12 of the pre-installed frame 1 through the fastener 3, and then the height of the support assembly 2 is adjusted by the adjusting nut 23 until the pre-installed frame 1 is flush with the ceiling 101, that is, the abutting portion 13 is in contact with the ceiling 101, and finally the pre-installed frame 1 and the ceiling 101 are fixed with screws.

[0033] 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 component 2 on the outside of the pre-installed frame 1 and perpendicular to the ceiling 101, so that the end of the first threaded support member 21 can be fixedly connected to the pre-installed frame 1, and the end of the second threaded support member 22 abuts against the ceiling 101, thereby achieving fixation among the support component 2, the pre-installed frame 1 and the ceiling 101.

[0034] In addition, an operating hole 11 is opened on the pre-installed frame 1 corresponding to the adjusting nut 23, so that a wrench can be inserted into the operating hole 11 to adjust the adjusting nut 23, so that the first threaded support 21 and the second threaded support 22 move in opposite directions, thereby driving the pre-installed frame 1 to rise until the lower surface of the pre-installed frame 1 is flush with the ceiling 101.

[0035] 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 for disassembly and assembly, safe and reliable, makes good use of the ceiling space, and enhances the aesthetic feeling of home decoration.

[0036] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
