[0059] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0060] This embodiment provides a movable installation device for lighting fixtures in building corridors, such as Figure 1-5As shown, it includes: a shell 1, a support rod 2, a limiting structure, an extrusion fixing structure and a lamp installation structure 3; wherein the shell 1 has an installation cavity, with through holes 11 opened on both sides opposite to each other; there are at least two support rods 2, which are telescopically installed in the installation cavity through telescopic structures, and one end of the two support rods 2 extends from the through holes 11 on both sides to the outside of the shell 1; both of the support rods 2 have a contracted state and an extended state; when one support rod 2 is extended or retracted, the other support rod 2 is extended or retracted synchronously accordingly; the limiting structure is used to limit and fix the two support rods 2 that are initially extended or retracted into position; the extrusion fixing structure further drives the support rods 2 to extend or retract by driving the limiting structure to achieve disassembly and assembly; the lamp mounting seat 3 is fixedly installed under the limiting structure and is suitable for installing lamps.

[0061] When using the movable lamp installation device for building corridors of this embodiment, one side support rod 2 is pulled outward, and the other side support rod 2 is extended synchronously until both support rods 2 are attached to the walls on both sides; when the support rods 2 are attached to the wall, the support rods 2 are fixed by the limiting structure, and then the limiting structure is driven by the extrusion fixing structure so that the support rods 2 exert pressure on the wall, thereby fixing it; after the support rods 2 are fixed, the lamp is installed under the lamp mounting seat 3. The movable lamp installation device for building corridors of this embodiment does not require drilling operations in the installation area when temporarily installing lamps, thus avoiding problems such as noise interference and dust pollution generated during the drilling process; it provides a convenient, efficient and safe installation method for temporary lamp installation.

[0062] like Figure 7 and Figure 8 As shown, the telescopic structure includes: a rotating gear 4, a first rack 41, and a second rack 42; wherein the rotating gear 4 is rotatably mounted in the mounting cavity; the first rack 41 is fixedly mounted on one of the support rods 2 opposite to the rotating gear 4; the second rack 42 is fixedly mounted on the other of the support rods 2 opposite to the rotating gear 4; the first rack 41 and the second rack 42 are arranged parallel to each other and are both meshed with the rotating gear 4. During installation, when one support rod 2 is pulled outward, the other support rod 2 will be extended synchronously through the linkage of the telescopic structure, thereby ensuring that the lengths of the two support rods 2 remain consistent, making the installation operation more convenient, efficient, and hassle-free.

[0063] Mounting holes 12 are formed in the top and bottom of the housing 1. Connecting shafts 43 are fixedly mounted at each end of the rotating gear 4. These connecting shafts 43 are mounted in the mounting holes 12, thereby rotatably mounting the rotating gear 4 within the housing 1. The housing 1 includes a base and a top cover screwed onto the top of the base. Mounting holes 12 are formed in the base and top cover, respectively. One end of the connecting shaft 43 is mounted in the mounting hole 12 of the base, and the other end is mounted in the mounting hole 12 of the top cover, thereby rotatably mounting the rotating gear 4.

[0064] like Figure 5 and Figure 6 As shown, the limiting structure includes: a sliding block 5, a connecting rod 52, a moving nut 53, a first elongated opening 54, a second elongated opening 55 and a first fixing hole 22; wherein there are two sliding blocks 5, which are movably mounted in the mounting cavity and are located on both sides of the rotating gear 4, and a first fixing bolt 51 is screwed on the sliding block 5; there are two connecting rods 52, which are hinged to the bottom of the two sliding blocks 5 respectively; the two ends of the moving nut 53 are hinged to the other ends of the two connecting rods 52 respectively; the first elongated opening 54 is opened at the bottom of the housing 1 opposite to the sliding block 5, and the bottom of the sliding block 5 can extend downward from the first elongated opening 54; the second elongated opening 55 is opened at the bottom of the housing 1, and is arranged parallel to the first elongated opening 54, and the setting position is opposite to the setting position of the first fixing bolt 51 above and below; there are several first fixing holes 22, which are evenly opened at the bottom of the support rod 2, and the first fixing bolt 51 can be installed into the first fixing hole 22 to limit and fix the support rod 2. When the support rod 2 is extended and retracted into place, the sliding block 5 is moved to install the first fixing bolt 51 into the first fixing hole 22 at the bottom of the support rod 2 to limit and fix the support rod 2, thereby enhancing the stability of the entire device.

[0065] like Figure 5 and Figure 6 As shown, a connecting portion 56 is fixedly provided at the bottom of the sliding block 5, and the connecting portion 56 passes through the first elongated opening 54 and is hingedly connected to the connecting rod 52. A through hole is formed in the connecting portion 56, and connecting holes are formed on opposite sides of the two connecting rods 52. Rivets are passed through the connecting holes and the through holes to hinge the connecting portion 56 and the connecting rods 52 together.

[0066] like Figure 10 and Figure 12As shown, the extrusion fixing structure includes: a bearing seat 6, a screw 63 and a transmission bearing 66; wherein, the bearing seat 6 is fixedly mounted on the bottom of the housing 1, and is provided with a first through-hole 61, and a bearing mounting position 62 is provided inside; the screw 63 passes through the first through-hole 61, and the top is restricted in the bearing seat 6 by a limiting portion 64, and a square end 65 is fixedly provided at the bottom; the movable nut 53 is screwed onto the screw 63; the rotating bearing 66 is sleeved on the screw 63 and fixedly mounted in the bearing mounting position 62, so that the screw 63 is rotatably mounted on the bearing seat 6. After the support rod 2 is fixed by the limiting structure, the direction end 65 at the bottom of the screw 63 is rotated to rotate the movable nut 53 upward, and the movable nut 53 drives the connecting rods 52 on both sides to push the sliding block 5 toward the walls on both sides, thereby further squeezing and fixing the support rod 2; this fixing method is not only firm and reliable, but also effectively prevents loosening or falling off due to long-term use or under the action of external forces.

[0067] like Figure 11 As shown, the support rod 2 defines a movable cavity 23 with an open end, and a support base 7 is fixedly mounted on one end of the support rod 2. The support rod 2 also includes an auxiliary support rod 71, which is telescopically mounted within the movable cavity 23. Its free end extends out of the movable cavity 23 and further out of the through hole 11, where it is fixedly connected to the support base 7. When the support rod 2 is extended or retracted, the auxiliary support rod 71 follows. The auxiliary support rod 71 acts as additional support, working together with the support rod 2 to bear the weight and external forces of the lamp, thereby improving the load-bearing capacity and preventing structural damage or deformation caused by excessive weight.

[0068] like Figure 5 and Figure 6 As shown, the bottom of the auxiliary support rod 71 is provided with a plurality of second fixing holes 72, and the sliding block 5 is threaded with a second fixing bolt 73. A third elongated opening 74 is provided at the bottom of the housing 1, and is positioned vertically opposite the position of the second fixing bolt 73. The second fixing bolt 73 can be installed into the second fixing hole 72 to fix the auxiliary support rod 71 in place. When the auxiliary support rod 71 is extended and retracted into place, the sliding block 5 is moved to install the second fixing bolt 73 into the second fixing hole 73 at the bottom of the auxiliary support rod 71, fixing the auxiliary support rod 71 in place.

[0069] like Figure 7 As shown, the lamp mount 3 has a second through-hole 31, and a plurality of lamp mounting holes 32 are formed on either side of the second through-hole 31. The lamp mount 3 is fixedly connected to the movable nut by passing the screw 63 through the second through-hole 31. The plurality of lamp mounting holes 32 on the lamp mount 3 meets the installation requirements of various lamps and improves versatility.

[0070] like Figure 9 As shown, a rubber support pad 75 is fixedly provided on the outside of the support base 7. The rubber support pad 75 is soft and elastic, and can prevent the support rod 2 from directly squeezing the wall and leaving an indentation on the wall.

[0071] The method of using the movable installation device for lamps in building corridors in this embodiment is as follows:

[0072] After the cam 7 is in contact with the wall, the first and second fixing holes 22 at the bottom of the support rod 2 are moved, and the second fixing holes 73 at the bottom of the auxiliary support rod 71 are moved to fix the support rod 2 and the auxiliary support rod 71 in a fixed position. Then, use a tool to rotate the direction end 65 at the bottom of the screw 63 to rotate the moving nut 53 upward, and the moving nut 53 drives the connecting rods 52 on both sides to push the sliding block 5 to move toward the walls on both sides, thereby further squeezing and fixing the support rod 2 and the auxiliary support rod 71.

[0073] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this innovative technical solution.
