Description

Technical Field

[0001] This application relates to the field of lighting installation, and more particularly to a lighting installation structure for building curtain walls. Background Technology

[0002] Building curtain walls refer to the non-load-bearing exterior wall cladding of a building. They are lightweight wall structures with decorative effects commonly used in modern large and high-rise buildings. To enhance the lighting effect of the curtain wall, lighting fixtures are usually installed on the curtain walls of high-rise buildings.

[0003] Currently, the lighting fixture consists of a fixture body and a mounting base. The mounting base has pre-drilled mounting holes, and nuts are also pre-drilled on the curtain wall. During installation, bolts are threaded through the mounting holes and connected to the nuts to install the mounting base onto the curtain wall, and then the fixture body is fixedly connected to the mounting base.

[0004] Regarding the aforementioned technologies, after a period of use, the bolts and nuts between the lamp mounting base and the curtain wall may loosen, leading to unstable installation between the lamp mounting base and the curtain wall. Summary of the Invention

[0005] To improve the installation stability between the lamp mounting base and the curtain wall, this application provides a lamp mounting structure for building curtain walls.

[0006] The technical solution for the architectural curtain wall lighting fixture installation structure provided in this application is as follows:

[0007] A building curtain wall lighting fixture installation structure includes a curtain wall, a lighting fixture mounting base, and a clamping assembly. The curtain wall contains several nuts, and the lighting fixture mounting base has several mounting holes. The curtain wall and the lighting fixture mounting base are fixedly connected by several first bolts passing through the mounting holes and threadedly connected to the nuts. The lighting fixture mounting base has a mounting cavity, and the several first bolts have clamping grooves communicating with the mounting cavity. The clamping assembly includes a lead screw, a threaded sleeve, several pressure rods, and several limiting rods. The lead screw is rotatably connected to the mounting cavity, and the threaded sleeve is threadedly connected to the lead screw. The pressure rods and limiting rods are spaced apart circumferentially along the threaded sleeve. One end of each pressure rod is fixedly connected to the threaded sleeve, and the other end extends into the clamping groove and abuts against the end of the first bolt located in the clamping groove near the curtain wall. The pressure rod has a clearance hole, and the limiting rod passes through the clearance hole.

[0008] By adopting the above technical solution, after the first bolt and nut are fixed to the curtain wall and the lamp mounting base, by rotating the screw, under the action of the limiting rod restricting the rotation of the pressure rod, the pressure rod and the threaded sleeve move towards the side closer to the curtain wall. The end of the pressure rod away from the threaded sleeve abuts against the end of the first bolt located in the clamping groove near the curtain wall, thereby clamping and limiting the first bolt, effectively preventing the first bolt and nut from loosening, thereby improving the installation stability between the lamp mounting base and the curtain wall, and thus making the lamp installation firm.

[0009] Preferably, a plurality of fixing sleeves are provided inside the curtain wall, and the end of each limiting rod near the curtain wall is inserted into the fixing sleeve.

[0010] By adopting the above technical solution, after the lamp mounting base is fixed, the limiting rod is squeezed to move towards the side closer to the curtain wall, and the limiting rod is inserted into the fixing sleeve to further install and fix the lamp mounting base to the curtain wall, thereby improving the installation stability between the lamp mounting base and the curtain wall, and also further preventing the first bolt and nut from loosening.

[0011] Preferably, the fixing sleeve is provided with a plurality of V-shaped spring pieces spaced apart along its circumference, and the limiting rod is inserted between each of the V-shaped spring pieces.

[0012] By adopting the above technical solution and setting several V-shaped springs, each V-shaped spring can make the limiting rod more firmly inserted into the fixing sleeve through elasticity, thereby improving the installation stability between the lamp mounting base and the curtain wall.

[0013] Preferably, the limiting rod has an annular locking groove along its circumference, and each of the V-shaped spring pieces is engaged in the annular locking groove.

[0014] By adopting the above technical solution and setting an annular snap-fit ​​groove, the firmness of the limit rod being inserted into the fixed sleeve is further improved.

[0015] Preferably, it also includes a transmission assembly, which includes a driving gear and a plurality of driven gears. The driving gear meshes with the plurality of driven gears. The driving gear is fixedly connected to the lead screw and located at the end of the threaded sleeve away from the curtain wall. The driven gear is rotatably fixed to the lamp mounting base and threadedly connected to the limiting rod. The limiting rod has a groove along its own length direction. The pressure rod has a protrusion at the clearance hole, and the protrusion is embedded in the groove.

[0016] By adopting the above technical solution, the drive gear is driven to rotate by rotating the lead screw, and the drive gear drives each driven gear to rotate. Since the driven gear is threadedly connected to the limit rod, and the protrusion is embedded in the groove to restrict the rotation of the limit rod, when the driven gear rotates, it drives the limit rod to move towards the end closer to the curtain wall, so that the limit rod is inserted into the fixing sleeve. Therefore, while rotating the lead screw to press the pressure rod to tighten the first limiting bolt, it drives the limit rod to be inserted into the fixing sleeve, so as to facilitate the installation and fixing of the lamp mounting base and the curtain wall, thereby improving the installation efficiency.

[0017] Preferably, the transmission assembly is disposed within the mounting cavity.

[0018] By adopting the above technical solution and setting the transmission component inside the mounting cavity, the space of the mounting cavity is fully utilized, thereby reducing the size of the lamp mounting base.

[0019] Preferably, it further includes a limiting component, which includes a plurality of limiting plates, the limiting plates being disposed in the pressing groove and located around the first bolt, and the pressure rod abutting against one side of the limiting plate.

[0020] By adopting the above technical solution and setting a limiting plate, after the first bolt is installed, the screw is rotated to make the pressure rod abut against the limiting plate. At this time, the limiting rod is inserted into the clearance hole to facilitate the positioning and installation of the limiting rod, thereby facilitating the installation of the lamp mounting base.

[0021] Preferably, the limiting component further includes a plurality of limiting blocks, the limiting blocks being located on the side of the first bolt away from the limiting plate, and the limiting blocks having limiting grooves for limiting the pressure rod.

[0022] By adopting the above technical solution and setting a limiting block, when the first bolt is installed, the pressure rod is limited and embedded in the limiting groove, so as not to interfere with the pressure rod, thus facilitating the installation of the first bolt.

[0023] Preferably, it also includes a lamp body, wherein the lamp body and the lamp mounting base are fixed by a plurality of second bolts threaded through the lamp body and the mounting hole, and the second bolts abut against the first bolt.

[0024] By adopting the above technical solution, and by setting the lamp body and the second bolt, the second bolt fixes the lamp body and the lamp mounting base while pressing against the first bolt, further preventing the first bolt and nut from loosening.

[0025] Preferably, a sealing rubber gasket is provided between the lamp body and the lamp mounting base.

[0026] By adopting the above technical solution and setting a sealing rubber gasket, dust or moisture can be reduced from entering the installation cavity.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the first bolt and nut are fixed to the curtain wall and the lighting fixture mounting base, by rotating the screw, under the action of the limiting rod restricting the rotation of the pressure rod, the pressure rod and the threaded sleeve move towards the side closer to the curtain wall. The end of the pressure rod away from the threaded sleeve abuts against the end of the first bolt located in the clamping groove closer to the curtain wall, clamping and limiting the first bolt, effectively preventing the first bolt and nut from loosening, thereby improving the installation stability between the lighting fixture mounting base and the curtain wall, and thus making the lighting fixture installation firm;

[0029] 2. After the lamp mounting base is fixed, squeeze the limiting rod to move it toward the side closer to the curtain wall, and insert the limiting rod into the fixing sleeve to further install and fix the lamp mounting base to the curtain wall, improve the installation stability between the lamp mounting base and the curtain wall, and also further prevent the first bolt and nut from loosening;

[0030] 3. By rotating the lead screw, the driving gear is driven to rotate, which in turn drives each driven gear to rotate. Since the driven gears are threadedly connected to the limit rod, and the protrusion is embedded in the groove to restrict the rotation of the limit rod, when the driven gear rotates, it drives the limit rod to move towards the end closer to the curtain wall, so that the limit rod is inserted into the fixing sleeve. Therefore, while rotating the lead screw to press the pressure rod to tighten the first limiting bolt, it drives the limit rod to be inserted into the fixing sleeve, so as to facilitate the installation and fixing of the lamp mounting base to the curtain wall, thereby improving the installation efficiency.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses an installation structure for lighting fixtures on building curtain walls.

[0039] Reference Figure 1 and Figure 2 The building curtain wall lighting fixture installation structure includes a curtain wall 1, a lighting fixture mounting base 2, and a clamping assembly 3. Several nuts 11 are pre-embedded in the curtain wall 1. The lighting fixture mounting base 2 has several mounting holes 21 corresponding to the nuts 11. The mounting holes 21 are stepped holes, and a first bolt 4 is installed in each mounting hole 21. The first bolt 4 passes through the mounting hole 21 and is threadedly connected to the nut 11, thus fixing the curtain wall 1 to the lighting fixture mounting base 2. The lighting fixture mounting base 2 has mounting cavities 22 communicating with each mounting hole 21. A clamping groove 41 is formed on the first bolt 4, and the clamping groove 41 communicates with the mounting cavity 22. The clamping assembly 3 includes a lead screw 31, a threaded sleeve 32, several pressure rods 33, and several limiting rods 34. The lead screw 31 is located within the mounting cavity 22, and both ends are rotatably connected to the lighting fixture mounting base 2. The threaded sleeve 32 is threadedly connected to the lead screw 31. A number of pressure rods 33 and a number of limiting rods 34 correspond to a number of nuts 11, and the pressure rods 33 and the limiting rods 34 are spaced apart circumferentially along the lead screw 31. One end of the pressure rod 33 is integrally connected to the threaded sleeve 32, and the other end extends into the clamping groove 41 and abuts against the end of the first bolt 4 located in the clamping groove 41 near the curtain wall 1. Each limiting rod 34 is arranged parallel to the lead screw 31, and a relief hole 331 is provided on the pressure rod 33. The limiting rod 34 passes through the relief hole 331 to limit the rotation of the pressure rod 33.

[0040] After the curtain wall 1 and the lamp mounting base 2 are fixed by the first bolt 4 and nut 11, the screw 31 is rotated. Under the action of the limiting rod 34 restricting the rotation of the pressure rod 33, the pressure rod 33 and the threaded sleeve 32 move toward the side closer to the curtain wall 1. The end of the pressure rod 33 away from the threaded sleeve 32 abuts against the end of the first bolt 4 located in the clamping groove 41 near the curtain wall 1, which clamps and limits the first bolt 4, effectively preventing the first bolt 4 and nut 11 from loosening, thereby improving the installation stability between the lamp mounting base 2 and the curtain wall 1, and thus making the lamp installation firm.

[0041] Reference Figure 2 and Figure 3 Several fixing sleeves 12 are also pre-embedded inside the curtain wall 1. The number of fixing sleeves 12 corresponds to the number of limiting rods 34, and the axis of the fixing sleeve 12 and the axis of the limiting rod 34 are on the same straight line. The fixing sleeve 12 is in the shape of a ring. The end of the limiting rod 34 near the curtain wall 1 is inserted into the fixing sleeve 12 to further install and fix the lamp mounting base 2 to the curtain wall 1.

[0042] Specifically, a number of V-shaped spring pieces 123 are welded to the inner wall of the fixing sleeve 12, and these V-shaped spring pieces 123 are evenly spaced along the circumference of the fixing sleeve 12. The V-shaped protrusions of the V-shaped spring pieces 123 are positioned close to the limiting rod 34, so that the limiting rod 34 is tightly inserted between each V-shaped spring piece 123. Furthermore, the limiting rod 34 has an annular locking groove 341 along its circumference, which is adapted to each V-shaped spring piece 123. Each V-shaped spring piece 123 is engaged in the annular locking groove 341, making the limiting rod 34 more firmly inserted into the fixing sleeve 12, thereby improving the installation stability between the lamp mounting base 2 and the curtain wall 1.

[0043] Reference Figure 2 and Figure 4 The system also includes a transmission assembly 5, which is housed within the mounting cavity 22 to reduce the size of the lamp mounting base 2. The transmission assembly 5 includes a driving gear 51 and several driven gears 52. The driving gear 51 is fixedly connected to the lead screw 31 and located at the end of the threaded sleeve 32 away from the curtain wall 1. The number of driven gears 52 is the same as the number of limiting rods 34, and the axes of the driven gears 52 and the limiting rods 34 are aligned. Each driven gear 52 meshes with the driving gear 51. A rotating sleeve 521 is integrally connected to the end of each driven gear 52 away from the threaded sleeve 32, and the rotating sleeve 521 is rotatably fixed to the lamp mounting base 2. The driven gear 52 has an internal thread, and the limiting rod 34 has an external thread, allowing the driven gear 52 to be threadedly connected to the limiting rod 34 through the internal and external threads. Furthermore, the limiting rod 34 has a groove 342 along its own length direction, and the pressure rod 33 has a protrusion 332 integrally provided at the relief hole 331. The protrusion 332 is embedded in the groove 342 to restrict the rotation of the limiting rod 34.

[0044] By rotating the lead screw 31, the driving gear 51 is driven to rotate, and the driving gear 51 drives each driven gear 52 to rotate. Since the driven gear 52 is threadedly connected to the limiting rod 34, and the protrusion 332 is embedded in the groove 342 to restrict the rotation of the limiting rod 34, when the driven gear 52 rotates, it drives the limiting rod 34 to move towards the end closer to the curtain wall 1, so that the limiting rod 34 is inserted into the fixing sleeve 12. It can drive the limiting rod 34 to be inserted into the fixing sleeve 12 at the same time as rotating the lead screw 31 to press the pressure rod 33 to press the limiting first bolt 4, so as to facilitate the installation and fixing of the lamp mounting base 2 and the curtain wall 1, thereby improving the installation efficiency.

[0045] Reference Figure 2 and Figure 4 It also includes a limiting component 6, which comprises several limiting plates 61 and several limiting blocks 62, the number of which is the same as the number of the first bolts 4. The limiting plates 61 are fixedly connected to the first bolts 4 at both ends, are located within the clamping groove 41 and around the periphery of the first bolts 4, and one side of the pressure rod 33 abuts against one side of the limiting plate 61 to restrict further rotation of the pressure rod 33. The limiting blocks 62 are located on the side of the first bolts 4 away from the limiting plates 61, and have limiting grooves 621 for embedding the limiting pressure rod 33.

[0046] Reference Figure 4 and Figure 5 It should be noted that, in order to facilitate the installation of various components within the lamp mounting base 2, the lamp mounting base 2 includes a first mounting part 23 and a second mounting part 24, with the mounting cavity 22 located between the first mounting part 23 and the second mounting part 24. A mounting hole 21 is provided in the first mounting part 23, and one end of the lead screw 31 is rotatably fixed to the first mounting part 23. The driven gear 52 is rotatably fixed to the second mounting part 24 via a rotating sleeve 521, and a limiting rod 34 is threadedly connected to the driven gear 52.

[0047] When installing the lamp mounting base 2, first install the first mounting part 23, aligning each mounting hole 21 with each nut 11. At this time, the pressure rod 33 is embedded and limited in the limiting groove 621. The first bolt 4 is misaligned with the pressure rod 33, so that the first bolt 4 does not interfere with the pressure rod 33 during installation, thus facilitating the installation of the first bolt 4. After the first bolt 4 is installed, rotate the screw 31 to drive the pressure rod 33 to rotate, disengaging the pressure rod 33 from the limiting groove 621 and positioning it against the limiting plate 61. Then, fix the second mounting part 24 to the first mounting part 23. The fixing connection can be achieved by bolt connection or snap-fit. At this time, the pressure rod 33 passes through the groove 342 into the relief hole 331, and the other end of the screw 31 is rotatably fixed to the second mounting part 24 to facilitate the positioning and installation of the relief hole 331, thereby facilitating the assembly and installation of the lamp mounting base 2.

[0048] Reference Figure 4The system also includes a lamp body 7, which is fixed to the lamp mounting base 2 by several second bolts 8. Specifically, the second bolts 8 are located inside the lamp body 7, and the end of the mounting hole 21 away from the curtain wall 1 has an internal thread. The external thread at the end of the second bolt 8 is threaded with the internal thread. Furthermore, the end of the second bolt 8 abuts against the first bolt 4, so that the second bolt 8 fixes the lamp body 7 and the lamp mounting base 2 while abutting against the first bolt 4, further preventing the first bolt 4 and nut 11 from loosening. A sealing rubber gasket 9 is provided between the lamp body 7 and the lamp mounting base 2. The sealing rubber gasket 9 reduces the entry of dust or moisture into the mounting cavity 22, thereby reducing damage to the components in the mounting cavity 22 and improving service life.

[0049] The implementation principle of this embodiment is as follows: After the curtain wall 1 and the lamp mounting base 2 are fixed by the first bolt 4 and nut 11, the screw 31 is rotated. Under the action of the limiting rod 34 restricting the rotation of the pressure rod 33, the pressure rod 33 and the threaded sleeve 32 move toward the side closer to the curtain wall 1. The end of the pressure rod 33 away from the threaded sleeve 32 abuts against the end of the first bolt 4 located in the pressing groove 41 near the curtain wall 1, pressing and limiting the first bolt 4, effectively preventing the first bolt 4 and nut 11 from loosening, thereby improving the installation stability between the lamp mounting base 2 and the curtain wall 1, and thus making the lamp installation firm. While rotating the lead screw 31, the driving gear 51 is driven to rotate. The driving gear 51 drives each driven gear 52 to rotate. Since the driven gear 52 is threadedly connected to the limiting rod 34, and the protrusion 332 is embedded in the groove 342 to restrict the rotation of the limiting rod 34, when the driven gear 52 rotates, it drives the limiting rod 34 to move towards the end closer to the curtain wall 1, so that the limiting rod 34 is tightly inserted into the fixing sleeve 12. It is not necessary to separately insert the limiting rod 34 into the fixing sleeve 12, so as to facilitate the installation and fixation of the lamp mounting base 2 and the curtain wall 1, thereby improving the installation efficiency.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
