Description

Technical Field

[0001] This application relates to the technical field of lighting decoration, and particularly to an anti-seismic structure for installing a chandelier and a chandelier. Background Art

[0002] A chandelier refers to a high-grade decorative lighting fixture hung on the indoor ceiling layer. Especially in a dining room, chandeliers are widely liked by people. Conventional chandeliers on the market are rigidly connected to the ceiling layer. For example, a mounting plate is fixed on the ceiling layer, and then the suspension rod of the chandelier is fixedly connected to the mounting plate through screws. After installation, the chandelier is relatively fixed to the ceiling layer and cannot shake relative to it.

[0003] With the improvement of people's living quality, chandeliers are increasingly used on cruise ships. However, during the navigation of a cruise ship, the hull will always shake. Since the installation of chandeliers is rigidly connected to the ceiling layer, the connection part between the suspension rod and the mounting plate will become loose and worn due to vibration, ultimately affecting the service life of the chandelier. Summary of the Invention

[0004] In order to reduce the influence of vibration on the connection part between the suspension rod and the mounting plate, this application provides an anti-seismic structure for installing a chandelier.

[0005] An anti-seismic structure for installing a chandelier provided by this application adopts the following technical solutions:

[0006] An anti-seismic structure for installing a chandelier includes a suspension rod for connecting the chandelier, a limit head and a limit frame assembly connected to the suspension rod; the limit frame assembly includes a threaded rod for connecting to the ceiling layer and a mounting plate connected to the threaded rod; a lower opening for the suspension rod to pass through is formed on the mounting plate, the lower end of the limit head is arc-shaped, and a part of the lower end entity of the limit head is embedded at the lower opening and abuts against the mounting plate to limit the limit head from moving downward in the vertical direction; a plurality of extension columns are arranged on the limit head, and there is a gap between the extension columns and the ceiling layer.

[0007] By adopting the above technical solutions, under the gravity of the suspension rod and the like, a part of the lower end entity of the limit head is located at the lower opening and abuts against the mounting plate, so that the chandelier can be hung on the ceiling layer. When the cruise ship is in motion and the hull shakes, since the limit head and the limit frame assembly can move relative to each other, the suspension rod can move in the horizontal and vertical directions. Compared with the way that the suspension rod is directly connected to the mounting plate by screws, this application relieves the force at the connection between the suspension rod and the mounting plate through the movable connection setting, reduces the influence of vibration on the connection part between the suspension rod and the mounting plate, and improves the service life of the chandelier.

[0008] Optionally, the limiting frame assembly further includes an upper disc connected to the threaded rod. The upper disc is located above the mounting plate and has an upper through-hole. A plurality of the extension columns pass through the upper through-hole, and there is a gap between the extension columns and the hole wall of the upper through-hole.

[0009] By adopting the above technical solution, the upper disc plays a role in limiting the limiting head, restricting the moving range of the hanging rod, and further restricting the moving range of the chandelier relative to the top plate layer, reducing the probability of wear and tear of the chandelier itself due to excessive shaking.

[0010] Optionally, the maximum distance between the upper ends of the plurality of extension columns is greater than the maximum aperture of the upper through-hole.

[0011] By adopting the above technical solution, the plurality of extension columns cannot completely pass through the upper through-hole. When the mounting plate moves downward relative to the threaded rod due to long-term use, the upper disc will limit the plurality of extension columns in the vertical direction, thereby restricting the downward movement of the limiting head, thus playing a role in preventing the chandelier from falling.

[0012] Optionally, the upper disc is provided with an upper through-hole for the threaded rod to pass through, and an upper nut is threadedly connected to the threaded rod at the lower end of the upper disc; the mounting plate is provided with a lower through-hole for the threaded rod to pass through, and a lower nut is threadedly connected to the threaded rod at the upper and lower ends of the mounting plate.

[0013] By adopting the above technical solution, the upper disc is moved upward along the circumference of the threaded rod, and then the upper nut is rotated upward to fix the upper disc. The fixing method of the mounting plate is the same, and the mounting plate is fixed by setting lower nuts at both the upper and lower ends of the mounting plate. This connection method is not only convenient for installation but also can adjust the distance between the mounting plate and the lower disc.

[0014] Optionally, the limiting frame assembly further includes a metal sleeve sleeved on the threaded rod. The lower end of the metal sleeve abuts against the upper end of the upper disc, and the upper end of the metal sleeve can abut against the top plate layer.

[0015] By adopting the above technical solution, the addition of the metal sleeve restricts the upward movement of the upper disc towards the top plate layer, plays a role in stabilizing the upper disc, and has the effect of protecting the top plate layer. At the same time, when the threaded rod is subjected to a force moving relative to the top plate layer, the metal sleeve can bear a part of the acting force, reducing the mutual acting force between the threaded rod and the top plate layer, and playing a role in protecting the top plate layer and the threaded rod.

[0016] Optionally, the hanging rod, the limiting head, the mounting plate, the upper disc, and the extension columns are all metal parts.

[0017] By adopting the above technical solution, the use of metal parts has strong impact resistance and wear resistance.

[0018] Optionally, a support column corresponding to the extension column is fixedly connected to the upper disc. A square hole is formed in the support column. An inner storage bag and an outer storage bag are arranged on the support column. The inner storage bag and the outer storage bag are respectively located on both sides of the support column and cover both sides of the square hole. Filling sand is arranged in both the inner storage bag and the outer storage bag, and the inner storage bag and the outer storage bag communicate through the square hole; the inner storage bag is located between the extension column and the top plate layer.

[0019] By adopting the above technical solution, after the chandelier is installed on the top plate layer, by squeezing the outer storage bag, the filling sand in the outer storage bag is squeezed into the inner storage bag. The inner storage bag is located between the top plate layer and the extension column and has a certain limiting effect on the extension column. When the cruise ship shakes slightly during driving, the force on the chandelier is relatively small, and the setting of the inner storage bag plus the filling sand plays a role in stabilizing the hanging rod. When the force on the chandelier is relatively large, the extrusion force of the extension column on the inner storage bag becomes larger, and then the filling sand in the inner storage bag will be squeezed into the outer storage bag so that the hanging rod can move relative to the top plate layer. At the same time, the setting of the inner storage bag also avoids the direct impact of the extension column on the top plate layer, has a buffering effect, plays a role in protecting the top plate layer and the extension column, and reduces the generation of collision sounds.

[0020] Optionally, a deformable plastic baffle is arranged in the square hole. The lower end of the plastic baffle is fixedly connected to the lower hole wall of the square hole, and the upper end of the plastic baffle can move relative to the square hole.

[0021] By adopting the above technical solution, the setting of the plastic baffle plays a certain limiting role in the movement of the filling sand, and increases the stability of the filling sand in the inner storage bag.

[0022] Optionally, the plastic baffle is inclined towards the inner storage bag from bottom to top.

[0023] By adopting the above technical solution, it is convenient for the staff to squeeze the filling sand in the outer storage bag into the inner storage bag and prevent the filling sand in the inner storage bag from easily entering the outer storage bag.

[0024] In order to reduce the risk of damage to the connection part between the chandelier and the top plate layer due to vibration, the present application provides a chandelier.

[0025] The chandelier provided by the present application adopts the following technical solution:

[0026] A chandelier includes the above-mentioned anti-vibration installation structure for the chandelier, a lamp body connected to the hanging rod, and a protective cover connected to the top plate layer; the limiting head and the limiting frame assembly are located in the protective cover.

[0027] By adopting the above technical solution, the limiting head can move relative to the limiting frame assembly. Compared with the way that the hanging rod is directly connected to the mounting plate by screws, in this application, the connection between the hanging rod and the mounting plate is unloaded through the movable connection setting, reducing the influence of vibration on the connection part between the hanging rod and the mounting plate, and improving the service life of the chandelier. The protective cover has the effect of protecting the limiting head and the limiting frame assembly.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. The limiting head can be movably connected relative to the top plate layer. Compared with the way that the hanging rod is directly connected to the mounting plate by screws, in the case where the chandelier often vibrates due to shaking, the service life of the chandelier is increased;

[0030] 2. The settings of the mounting plate, the upper circular plate, and the inner storage bag filled with filling sand all play a certain role in restricting the movement of the limiting head, and the hanging rod can be set according to the ideal state of people. For example, what is the maximum movement range of the chandelier and how much force it needs to receive to move, etc., improving the practicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following will Figures 1-4 further describe this application in detail with reference to the attached

[0037] Embodiment 1:

[0038] The embodiment of this application discloses an anti-seismic structure for installing a chandelier. Refer to Figure 1, including a limit frame assembly 1 for connecting the top plate layer 23 and a limit head 2. The limit head 2 is fixed to the suspension rod 22 of the chandelier by threaded connection. The top plate layer 23 includes a concrete layer and a decorative layer located below the concrete layer. The decorative layer can be gypsum board or paint, etc.

[0039] Refer to Figure 1 , the limit frame assembly 1 includes a threaded rod 3, an upper round plate 4, a mounting plate 5, a metal sleeve 6, an upper nut 7 and a lower nut 8. There are four threaded rods 3 arranged in a square pattern. The upper ends of the four threaded rods 3 are inserted into the top plate layer 23 and fixed to the concrete layer in the top plate layer 23. The upper round plate 4 is provided with an upper through hole 9 for the threaded rod 3 to pass through, and the mounting plate 5 is provided with a lower through hole 10 for the threaded rod 3 to pass through. Along the axial direction of the threaded rod 3 from top to bottom are the metal sleeve 6, the upper round plate 4, the upper nut 7, a lower nut 8, the mounting plate 5 and another lower nut 8 in sequence. Both the upper nut 7 and the lower nut 8 can be threadedly connected to the threaded rod 3. The upper round plate 4 is restricted by the metal sleeve 6 and the upper nut 7 to achieve stability, and the mounting plate 5 is restricted by the two lower nuts 8 to achieve stability.

[0040] Refer to Figure 1 , the mounting plate 5 is provided with a lower opening 11 for the suspension rod 22 to pass through, and the lower opening 11 is circularly arranged. The lower end of the limit head 2 is arc-shaped, and a part of the entity at the lower end of the limit head 2 is embedded at the lower opening 11 and abuts against the mounting plate 5 to limit the downward movement of the limit head 2 in the vertical direction. Two oppositely arranged extension columns 12 are fixedly connected to the upper end of the limit head 2. The upper round plate 4 is provided with an upper opening 13 for the extension columns 12 to pass through, and the extension columns 12 gradually extend outward along the direction away from the limit head 2, that is, the maximum distance between the upper ends of the two extension columns 12 is greater than the aperture of the upper opening 13, and the maximum distance between the lower ends of the two extension columns 12 is less than the aperture of the upper opening 13. The limit head 2 can pass through the upper opening 13.

[0041] Refer to Figure 1, there is a gap between the two extension columns 12 to facilitate the arrangement of electric wires. There is a gap between the outer side wall of the extension column 12 and the hole wall of the upper opening 13. Under the action of its own weight, the lower arc-shaped part of the limit head 2 is located at the lower opening 11 and abuts against the mounting plate 5, so that the chandelier can be hung on the top plate layer 23. When the cruise ship is in motion, the hull shakes greatly. The limit head 2 can move relative to the limit frame assembly 1. Compared with the way that the suspension rod 22 is directly connected to the mounting plate 5 by screws, in this application, the connection between the suspension rod 22 and the mounting plate 5 is unloaded through the movable connection setting, reducing the influence of vibration on the connection part between the suspension rod 22 and the mounting plate 5, and improving the service life of the chandelier. At the same time, the upper disc 4 limits the movement range of the extension column 12, thereby limiting the movement range of the limit head 2, and finally limiting the movement range of the suspension rod 22 and the chandelier, reducing the probability of damage to the chandelier itself due to excessive shaking. When the mounting plate 5 loosens and moves downward due to long-term pressure, the upper disc 4 can also limit the limit head 2 from continuing to move downward, preventing the chandelier from slipping completely, playing an insurance role and improving safety.

[0042] It should be mentioned that the limit head 2, the extension column 12, the threaded rod 3, the upper disc 4, the mounting plate 5, the metal sleeve 6, the upper nut 7 and the lower nut 8 are all metal parts, having strong impact resistance and wear resistance. Among them, the upper end of the metal sleeve 6 can abut against the top plate layer 23, and the lower end of the metal sleeve 6 abuts against the upper end of the upper disc 4. The setting of the metal sleeve 6 limits the movement of the upper disc 4 towards the top plate layer 23, plays a role in stabilizing the upper disc 4, and has the effect of protecting the top plate layer 23. At the same time, when the threaded rod 3 is subjected to a force moving relative to the top plate layer 23, the metal sleeve 6 can bear a part of the acting force, reducing the mutual acting force between the threaded rod 3 and the top plate layer 23, playing a role in protecting the top plate layer 23 and the threaded rod 3.

[0043] The specific working conditions are as follows:

[0044] Under the weight of the suspension rod 22 and the chandelier, the lower end of the limit head 2 is located and stable within the lower opening 11. When the hull shakes during the cruise ship's movement, the limit head 2 can move relative to the mounting plate 5. Compared with the way that the suspension rod 22 is directly connected to the mounting plate 5 by screws, it avoids loosening and wear at the connection due to the continuous acting force of vibration, and has the effect of improving the service life of the chandelier.

[0045] Embodiment Two:

[0046] Refer to Figure 2 、 Figure 3Unlike the first embodiment, support columns 24 are welded to the upper disc 4, and the extension columns 12 are arranged one-to-one with the support columns 24. The support columns 24 have square holes 14 formed in them, and an inner storage bag 15 and an outer storage bag 16 are affixed to the support columns 24. The openings of the inner storage bag 15 and the outer storage bag 16 respectively cover the two openings of the square holes 14, and the inner storage bag 15 is located between the upper end of the extension column 12 and the top plate layer 23. Both the inner storage bag 15 and the outer storage bag 16 are filled with sand 17.

[0047] Reference Figure 3 A stop cord 18 is sewn and fixed to the downward-facing side of the inner storage bag 15. A stop ring 19 is integrally formed on the side of the extension column 12 facing away from the support column 24. The stop cord 18 is wrapped around the stop ring 19 and securely connected to the stop ring 19 by tying a knot. The connection between the stop cord 18 and the stop ring 19 stabilizes the inner storage bag 15 between the upper end of the extension column 12 and the top plate layer 23.

[0048] Reference Figure 3 A deformable plastic baffle 20 is disposed within the square hole 14. The lower end of the plastic baffle 20 is fixedly connected to the lower wall of the square hole 14, while the upper end of the plastic baffle 20 is movable relative to the square hole 14. The plastic baffle 20 is tilted upward from bottom to top toward the inner storage bag 15. The provision of the plastic baffle 20 restricts the movement of the filling sand 17, thereby increasing the stability of the filling sand 17 within the inner storage bag 15. This facilitates the worker's ability to squeeze the filling sand 17 from the outer storage bag 16 into the inner storage bag 15, while preventing the filling sand 17 from the inner storage bag 15 from easily entering the outer storage bag 16.

[0049] The specific working conditions are as follows:

[0050] After the chandelier is installed on the roof deck 23, the inner storage bag 15 is positioned between the roof deck 23 and the extension column 12, providing a certain positional restraint for the extension column 12, thereby limiting the movement of the stopper 2 and the chandelier. When the cruise ship's swaying is minimal, the chandelier experiences minimal vibrational force, and the inner storage bag 15 and the sand filling 17 stabilize the boom 22. When the chandelier is subjected to greater forces, the extension column 12 exerts a greater pressure on the inner storage bag 15, forcing the sand filling 17 from the inner storage bag 15 into the outer storage bag 16, facilitating relative movement of the boom 22 relative to the roof deck 23 and gradually increasing the chandelier's range of motion. After stopping, the sand filling 17 from the outer storage bag 16 can be manually squeezed into the inner storage bag 15. Furthermore, the inner storage bag 15 prevents the extension column 12 from directly impacting the roof deck 23, providing a cushioning effect, protecting the roof deck 23 and the extension column 12 and reducing the occurrence of collision noise.

[0051] Example 3:

[0052] The present application also discloses a chandelier. Referring to Figure 4 , it includes an installation shockproof structure for the chandelier, a lamp body (not shown in the figure) connected to the lower end of the suspension rod 22, and a protective cover 21 detachably connected to the top plate layer 23. The limit head 2 and the limit frame assembly 1 are both located inside the protective cover 21, and the protective cover 21 has the effect of protecting the limit head 2 and the limit frame assembly 1.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
