Description

Technical Field

[0001] This utility model relates to the field of lighting accessories technology, specifically to a hanging wire structure for lighting fixtures. Background Technology

[0002] As lighting products become increasingly personalized and decorative, modern lighting fixtures, while fulfilling basic lighting functions, have gradually become important visual elements in interior spaces, widely used in various scenarios such as living rooms, dining rooms, bedrooms, and corridors. Design styles are becoming more diversified and customized, and installation structures are receiving increasing attention.

[0003] Currently, a double wire rope suspension structure is commonly used to suspend and position lighting fixtures. This involves connecting the light body with a first wire rope and then connecting the light body to the chandelier base on the ceiling with a second wire rope. The two wire ropes are connected through a through hole in the connecting assembly. To improve the flexibility of the hoisting, a rope clamping structure is often set in the connecting assembly to adjust the height of the second wire rope. While this type of rope clamping structure can meet the adjustment requirements, its clamping mechanism is usually only designed in the direction of the second wire rope, lacking a dedicated and effective locking structure for the first wire rope.

[0004] In practical applications, since the first steel wire rope is only inserted through the through hole and is not equipped with an independent clamping and locking mechanism, it often relies on the indirect clamping effect generated by the cooperation of components to achieve fixation. The clamping force is limited, the structure is easy to loosen, and the cylinder may slip on the first steel wire rope, which cannot guarantee the stability of the lamp body position and the safety of use. Utility Model Content

[0005] In order to overcome the defects of the prior art, the present invention provides a suspension wire structure for lighting fixtures. When the connecting component is screwed on, its bottom can press against the first steel wire suspension rope passing through the first through hole of the cylinder, thereby effectively locking and fixing the cylinder and realizing the stable suspension of the lighting fixture.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A pendant wire structure for lighting fixtures, comprising:

[0008] A cylindrical body having an installation cavity and a first through hole extending from the side of the cylindrical body through the installation cavity;

[0009] The first steel wire rope is threaded through the first through hole, and the cylinder can reciprocate on the first steel wire rope;

[0010] The connecting component is connected to the chandelier base fixed to the ceiling via a second steel wire rope;

[0011] The mounting cavity is provided with an internal thread, and the connecting assembly is provided with an external thread that mates with the internal thread. The connecting assembly is fixedly connected to the cylinder by the threaded connection between the external thread and the internal thread. When the connecting assembly is threadedly connected to the mounting cavity and squeezes the first steel wire rope, the cylinder can be locked onto the first steel wire rope.

[0012] Furthermore, the connecting assembly includes a connecting cylinder with the external thread, a connecting head, and a plurality of pressure beads;

[0013] The connecting cylinder has a second through hole and a contraction cavity communicating with the second through hole; the connecting head has a cone head that cooperates with the contraction cavity and a third through hole arranged along the length of the connecting head for one end of the second steel wire rope to pass through; the side of the cone head has a plurality of placement grooves communicating with the third through hole, and each of the rope pressing beads is movably installed in the corresponding placement groove.

[0014] Furthermore, the connecting assembly also includes an elastic element and a pressure block, the pressure block having a fourth through hole that allows one end of the second steel wire rope to pass through, and the pressure block being installed at the bottom of the connecting cylinder;

[0015] When the connecting assembly is threaded into the mounting cavity, the bottom of the pressure block and the first through hole press against each other to form the first wire rope and lock the cylinder onto the first wire rope.

[0016] The elastic element is sleeved on one end of the second steel wire rope and located in the second through hole. One end of the elastic element abuts against the pressure block, and the other end abuts against the cone head and applies elastic force to it, so as to drive the cone head to move towards the contraction cavity, thereby driving multiple pressure rope beads to abut against the wall of the contraction cavity and move towards the cone head, so that the multiple pressure rope beads clamp and fix one end of the second steel wire rope.

[0017] Furthermore, both ends of the first steel wire rope are provided with limiting blocks to prevent the cylinder from sliding out.

[0018] Furthermore, the limiting block includes a first limiting protrusion and a second limiting protrusion, and the first limiting protrusion and the second limiting protrusion form a stepped structure.

[0019] Furthermore, the chandelier base includes a mounting base and a downwardly protruding part located at the center of the mounting base. A fifth through hole is provided on the protruding part, and the other end of the second steel wire rope passes through the fifth through hole.

[0020] Furthermore, the protrusion is provided with a cavity for connecting a limiting component to the other end of the second steel wire rope to prevent it from slipping out.

[0021] Furthermore, a plurality of reinforcing ribs are provided between the protrusion and the mounting base and are arranged at intervals.

[0022] Furthermore, the protrusion, the mounting base, and the reinforcing rib are integrally formed.

[0023] Furthermore, the mounting chassis is also provided with a sixth through hole, a seventh through hole, and an eighth through hole for fasteners to pass through and be fixed to the ceiling.

[0024] In summary, this utility model has the following technical effects:

[0025] 1. This utility model relates to a suspension wire structure for lighting fixtures. After the connecting components are screwed together, their bottom can press against the first steel wire rope passing through the first through hole of the cylinder, thereby effectively locking and fixing the cylinder and achieving stable suspension of the lighting fixture. Compared with the traditional solution that only adjusts the second steel wire rope through the rope clamping component and lacks a locking mechanism for the first steel wire rope, this structure can effectively prevent the cylinder from sliding on the first steel wire rope while adjusting the height of the second steel wire rope, thus improving the overall stability and suspension safety of the lighting fixture.

[0026] 2. The suspension wire structure of this utility model for lighting fixtures utilizes the axial propulsion characteristic of the threaded connection itself to reliably clamp the first steel wire suspension rope without adding any additional structures or parts. The overall structure is simpler and more compact. Users only need to tighten the connecting components to complete the installation and positioning of the lamp body. The operation is convenient and does not require complicated assembly processes, which effectively improves installation efficiency, reduces manufacturing and maintenance costs, and also enhances the safety of the lighting fixture during use.

[0027] 3. This utility model relates to a suspension wire structure for lighting fixtures. The structure is easy to operate; users only need to tighten or loosen the connecting components to fix the lighting fixture, improving installation efficiency and ease of use. Simultaneously, it ensures the stability of the cylinder, enhancing the stability and safety of the lighting fixture during actual use. Furthermore, this structure has good repeatability and adaptability, compatible with different specifications of steel wire ropes and various lamp body styles, suitable for various scenarios such as homes, commercial spaces, and showrooms, possessing high practical value and market adaptability.

Detailed Implementation

[0038] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] like Figure 1-8 The diagram shows a hanging wire structure for lighting fixtures, including a cylindrical body 1, a first steel wire rope 2, and a connecting component 3; the cylindrical body 1 is provided with an installation cavity 11 and a first through hole 12 extending from the side of the cylindrical body 1 into the installation cavity 11; the first steel wire rope 2 is inserted into the first through hole 12, and the cylindrical body 1 can slide back and forth along the first steel wire rope 2.

[0042] The connecting component 3 is connected to the chandelier base 5 fixed to the ceiling via the second steel wire rope 4. The mounting cavity 11 has an internal thread (not shown in the figure), and the connecting component 3 has a mating external thread 313; the two are connected by screwing together. When the connecting component 3 is screwed into the mounting cavity 11, it locks the first steel wire rope 2 through-hole connecting component 3 and the first through-hole 12 by mutual compression, thereby locking the cylinder 1 onto the first steel wire rope 2. This threaded locking structure simplifies the complexity of the structure, effectively improves installation efficiency, and reduces structural costs and manufacturing difficulty.

[0043] See Figure 6-8 The connecting assembly 3 includes a connecting cylinder 31, a connecting head 32, and multiple pressure beads 33. The connecting cylinder 31 has an external thread 313 on its outer periphery, which can be screwed into the internal thread of the cylinder 1 to achieve overall locking and fixation. The connecting cylinder 31 has a second through hole 311 inside, and a contraction cavity 312 communicating with the second through hole 311, which is used to cooperate with the movement space of the internal locking structure.

[0044] The connector 32 is provided with a conical head 323 for inserting into the contraction cavity 312 to prevent the connector 32 from dislodging, and a third through hole 321 arranged along the length of the connector 32 for one end of the second steel wire rope 4 to pass through. The side of the conical head 323 has multiple placement grooves 322, each of which communicates with the third through hole 321, and a rope-pressing bead 33 is correspondingly and movably installed thereon. This structure, by placing multiple rope-pressing beads 33 in the radial placement grooves 322 around the conical head 323, achieves multi-point distributed clamping of the second steel wire rope 4 while maintaining a compact structure, thus enhancing locking stability.

[0045] Furthermore, the connecting assembly 3 also includes a pressure block 35 and an elastic element 34 disposed at the bottom of the connecting cylinder 31. The pressure block 35 is provided with a fourth through hole 351 for the second steel wire rope 4 to pass through, and is fixedly installed at the bottom of the connecting cylinder 31. When the connecting assembly 3 is screwed into the mounting cavity 11 of the cylinder 1, the bottom of the pressure block 35 can press against the first steel wire rope 2 with the first through hole 12 to achieve the clamping of the first steel wire rope 2, thereby reliably locking the cylinder 1 onto the first steel wire rope 2. This design simplifies the structure of the traditional multi-stage locking mechanism and effectively improves the overall assembly efficiency and clamping reliability.

[0046] Furthermore, the pressure block 35 has a mounting groove 352 communicating with the fourth through hole 351 to accommodate one end of the elastic element 34. The elastic element 34 is sleeved on one end of the second steel wire rope 4 and placed in the second through hole 311. One end of the elastic element 34 is inserted into the mounting groove 352 and abuts against the bottom of the mounting groove 352, while the other end abuts against the cone head 323. Through the elastic force of the elastic element 34, a continuous elastic force can be applied to the cone head 323, driving it to move towards the contraction cavity 312, thereby causing multiple rope-pressing beads 33 to tighten inward along the placement groove 322 and press against the wall of the contraction cavity 312, achieving stable clamping of the end of the second steel wire rope 4. This design not only improves the fixing reliability of the second steel wire rope 4, but also has good anti-loosening ability and long-term clamping performance, improving the overall safety and stability of the lighting fixture.

[0047] In actual use, the user can press the connector 32 to make the cone 323 overcome the elastic force of the elastic element 34 and move away from the contraction cavity 312, that is, towards the second through hole 311. During the movement, the cone 323 will drive multiple rope-pressing beads 33 to expand outward along the placement groove 322, thereby releasing their clamping effect on the end of the second wire rope 4 and realizing the loosening state of the second wire rope 4. At this time, the user can easily pull the second wire rope 4 to adjust the suspension height of the connecting assembly 3 on the second wire rope 4.

[0048] When the pressure applied to the connector 32 is released, the elastic element 34 returns to its original deformation and continues to apply elastic force to the cone 323, driving the cone 323 to automatically return to its original position in the direction of the contraction cavity 312. Subsequently, multiple rope-pressing beads 33, driven by the cone 323, converge inward along the placement groove 322 and press against the inner wall of the contraction cavity 312, thereby achieving a stable clamping of the end of the second steel wire rope 4. This clamping-releasing structure is responsive, easy to operate, and can achieve rapid positioning and reliable fixation of the height position of the connecting assembly 3.

[0049] With the above structural design, the entire adjustment process can be completed without the need for complex tools or disassembling the lamp body, effectively improving the flexibility of lamp installation and maintenance, lowering the operational threshold, and significantly improving the user experience. Simultaneously, the clamping mechanism formed by the cone head 323 and the pressure bead 33 can apply stable clamping force to the second steel wire rope 4 in a multi-point evenly distributed manner, ensuring reliable anti-loosening performance even in vibration or long-term use environments, thereby improving the safety and service life of the entire lighting hanging system.

[0050] It should be noted that, because the connecting cylinder 31 is screwed into the internal thread of the mounting cavity 11 via its external thread, and the pressure block 35 at its bottom presses against the first through hole 12, a reliable clamping of the first wire rope 2 is achieved, thus stably fixing the cylinder 1 to the first wire rope 2. Therefore, even if the suspension height of the connecting assembly 3 on the second wire rope 4 is adjusted by pressing the connector 32, it will not affect the locking state of the cylinder 1 on the first wire rope 2.

[0051] This structural design achieves height adjustment while ensuring the relative independence between the connecting component 3 and the cylinder 1. This allows the steel wire ropes in both directions to be independently positioned and fixed without interference, further enhancing the operational flexibility and structural stability during lighting installation. Furthermore, this structure effectively prevents cross-contamination or loosening during adjustment, ensuring the safety and reliability of the lighting fixture during long-term use.

[0052] Furthermore, the connecting cylinder 31 is provided with a protrusion 314. When the connecting cylinder 31 is screwed into the mounting cavity 11 and the cylinder body 1 is locked, the protrusion 314 can abut against one end of the cylinder body 1, thereby restricting the external thread 313 from continuing to screw into the mounting cavity 11 and also enhancing the connection stability. It should be noted that the protrusion 314 can be designed as a hexagon or other standard tool-fit shape to facilitate quick tightening with tools and enhance operational convenience.

[0053] Furthermore, when one end of the second wire rope 4 passes through the fourth through hole 351 on the pressure block 35 and extends from its bottom, a limiting block can be installed at the extended end by pressing or welding. The outer diameter of the limiting block is larger than the diameter of the fourth through hole 351, thus forming an end anti-reverse structure. This structure can effectively limit the axial sliding of the second wire rope 4 in the connecting assembly 3, playing an auxiliary limiting and anti-detachment role.

[0054] Under normal operating conditions, the second steel wire rope 4 is clamped stably by multiple rope-pressing beads 33, which, driven by the cone head 323, converge inward along the placement groove 322 and press against the inner wall of the contraction cavity 312. However, under extreme working conditions or during prolonged use, if the elastic element fatigues, causing the multiple rope-pressing beads 33 to fail to clamp the second steel wire rope 4, the limit block can act as a safety structure to prevent the second steel wire rope 4 from accidentally slipping out of the connecting assembly 3, thereby effectively avoiding the risk of the light fixture falling.

[0055] By incorporating this limit block, the redundancy protection performance of the entire hoisting structure can be significantly enhanced, improving the system's safety and reliability. It is particularly suitable for residential, commercial, and exhibition lighting applications with high safety requirements. This design not only improves the product's protective capabilities during use but also strengthens users' confidence in the stability of the hoisting structure.

[0056] It should be noted that the pressure block 35 can be fixedly installed at the bottom of the connecting cylinder 31 by interference fit or threaded connection, thereby achieving a stable structural connection. To further improve assembly accuracy and limiting effect, a boss 353 is provided at the bottom of the pressure block 35. The boss 353 is used to abut against the bottom of the connecting cylinder 31 to prevent the pressure block 35 from going too deep into the second through hole 311. It also helps to determine the installation position of the pressure block 35 and ensure its structural stability during the stress process.

[0057] Furthermore, in the extreme case where the structure securing the second wire rope 4 with multiple clamping beads 33 fails, the aforementioned limiting block located at the end of the rope can abut against the boss 353, thereby indirectly applying axial support force to the bottom of the connecting cylinder 31, forming a redundant limiting protection structure. This design not only further prevents the second wire rope 4 from accidentally slipping out of the connecting assembly 3, but also effectively maintains the minimum slip distance of the wire rope when the clamping mechanism loosens, providing additional safety assurance for the overall structure.

[0058] Of course, the pressure block 35 can be fixedly installed at the bottom of the connecting cylinder 31 by means of threaded connection, and it is also easy to disassemble it to facilitate the replacement and installation of the elastic element 34, the pressure bead and the connecting head 32.

[0059] like Figure 4 As shown, limit blocks 6 are respectively provided at both ends of the first steel wire rope 2 to restrict the sliding of the cylinder 1. The limit block 6 includes a first limit protrusion 61 and a second limit protrusion 62, which together form a stepped structure to prevent the cylinder 1 from slipping off, and at the same time facilitates the locking of the limit block 6 through the stepped structure with the top of the lampshade to achieve safe suspension of the lampshade.

[0060] See Figure 2-3As shown, the chandelier base 5 includes a mounting base 52 and a downwardly protruding part 51 located at its center. The protruding part 51 has a fifth through hole 511, through which the other end of the second steel wire suspension rope 4 is threaded and fixed. To enhance the structural strength of the base, multiple reinforcing ribs 53 are also provided between the protruding part 51 and the mounting base 52 at intervals. The protruding part 51, the mounting base 52, and the reinforcing ribs 53 are formed by a stamping integral molding process, further improving the overall stability and manufacturing efficiency.

[0061] The protrusion 51 is provided with a cavity 512 for installing a limiting component. The limiting component can be a limiting block. The other end of the second steel wire rope 4 can be placed in the cavity 512 by crimping or welding the limiting block. The diameter of the limiting block is larger than that of the fifth through hole 511, which effectively prevents the other end of the second steel wire rope 4 from coming out of the fifth through hole 511 and improves the safety of the overall structure.

[0062] Furthermore, the mounting base 52 is also provided with a sixth through hole 521, a seventh through hole 522 and an eighth through hole 523 for fasteners to pass through. In use, fasteners can pass through the sixth through hole 521, the seventh through hole 522 and the eighth through hole 523 to securely mount the mounting base 52 on the ceiling.

[0063] In summary, the suspension wire structure for lighting fixtures of this utility model, after the connecting component 3 is screwed in, can press against the first steel wire rope 2 that passes through the first through hole 12 of the cylinder 1, thereby effectively locking and fixing the cylinder 1 and achieving stable suspension of the lighting fixture. Compared with the traditional solution that only adjusts the second steel wire rope 4 through the rope clamping component and lacks a locking mechanism for the first steel wire rope 2, this structure can effectively prevent the cylinder from sliding on the first steel wire rope 2 while adjusting the height of the second steel wire rope 4, thus improving the overall stability and suspension safety of the lighting fixture.

[0064] This utility model relates to a suspension wire structure for lighting fixtures. By utilizing the axial propulsion characteristic of the threaded connection itself, it can reliably clamp the first steel wire suspension rope 2 without adding any additional structures or parts. The overall structure is simpler and more compact. Users only need to tighten the connecting component 3 to complete the installation and positioning of the lamp body. The operation is convenient and does not require complicated assembly processes, which effectively improves installation efficiency, reduces manufacturing and maintenance costs, and also enhances the safety of the lighting fixture during use.

Users only need to tighten or loosen the connecting component 3 to fix the lighting fixture, which improves installation efficiency and ease of use.

[0066] In addition, the structure has good repeatability and adaptability, and can be compatible with steel wire ropes of different specifications and various lamp body styles. It is suitable for various scenarios such as home, commercial, and exhibition hall, and has high practical value and market adaptability.
