Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an optimized structure for a chandelier balancer. Background Technology

[0002] In the field of indoor lighting, especially in the installation of chandeliers, it is often necessary to adjust the suspension height of the light fixtures according to actual usage needs. To meet this need, chandelier balancers are commonly used in the market. The core function of this type of device is to provide a controllable balancing force, allowing the light fixture to be stably suspended at different heights and allowing users to easily adjust the height.

[0003] Due to structural design limitations, traditional chandelier balancers typically come in two distinct styles: horizontal and vertical. Horizontal balancers are suitable for top-mounted applications, such as ceilings, while vertical balancers are suitable for side-mounted applications, such as walls. Manufacturers need to design, produce, and stock both models separately, increasing supply chain management costs and inventory pressure. For users and installers, this also means they need to choose a specific model based on the specific installation environment, lacking flexibility.

[0004] Furthermore, in order to generate, transmit, and adjust the balancing force, traditional designs of chandelier balancers typically rely on complex transmission systems, such as multi-stage gear transmission devices, specialized torque adjustment mechanisms, friction braking devices, and so on. These complex components result in products containing a dozen or even more parts, which not only increases production costs and assembly difficulty but also increases potential failure points, reducing the overall reliability and lifespan of the product. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing an optimized structure for a chandelier balancer, thereby solving the problems mentioned in the background art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An optimized structure for a chandelier balancer includes a mounting base with mounting plates installed around its perimeter for positioning. A winding wheel is movably mounted within the mounting base, with a cable wound on it. A spring wheel is integrally formed with the winding wheel on one side of the winding wheel. At least one spring mounting wheel is movably mounted on the mounting base corresponding to the spring wheel, with a constant-force spring wound on it. One end of the constant-force spring is fixed to the spring wheel. A cable opening is provided at the bottom of the mounting base, and a guide wheel is movably mounted at the opening. The cable can be directly passed through the opening and vertically connected to the chandelier, or its direction can be changed by the guide wheel and then vertically connected to the chandelier.

[0008] As a preferred embodiment of the optimized structure of the chandelier balancer, two spring mounting wheels are installed on the mounting base, and the constant force springs on the two spring mounting wheels are stacked and installed on the spring winding wheel.

[0010] As a preferred embodiment of the optimized structure of the chandelier balancer, the mounting base is provided with slots on all four sides, and the mounting plate is provided with a buckle on the side near the mounting base. The buckle is embedded in the slot, and a first insert rod is installed in the slot. The buckle is provided with a hole, and the first insert rod is inserted into the hole to position the buckle.

[0011] As a preferred embodiment of the optimized structure of the chandelier balancer, the mounting base is equipped with an upper cover and a lower cover at both ends, and the upper cover, the mounting base, and the lower cover together form a take-up box.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this utility model provides an optimized structure for a chandelier balancer, including a mounting base 1. A winding wheel 3 is movably mounted inside the mounting base 1, and a cable 4 is wound on the winding wheel 3. A spring winding wheel 5 is mounted on one side of the winding wheel 3. The spring winding wheel 5 and the winding wheel 3 are integrally formed, and their axes coincide, allowing the spring winding wheel 5 to rotate synchronously with the winding wheel 3, and their rotation periods are the same. At the same time, at least one spring mounting wheel 6 is movably mounted on the mounting base 1 corresponding to the position of the spring winding wheel 5. The axis of the spring mounting wheel 6 is parallel to that of the spring winding wheel 5. In this embodiment, two spring mounting wheels 6 and two springs are preferably used. Constant force springs 7 are wound around the mounting wheels 6. One end of the two constant force springs 7 is stacked on the spring winding wheel 5. When the spring winding wheel 5 rotates, the two constant force springs 7 can be wound up synchronously, which is suitable for chandeliers with larger weight. The bottom of the mounting base 1 is also provided with a cable opening 101. A guide wheel 8 is movably installed at the cable opening 101. When the chandelier balancer is installed vertically, the cable 4 on the winding wheel 3 passes directly through the cable opening 101 and is vertically connected to the chandelier below. When the chandelier balancer is installed horizontally, the cable 4 on the winding wheel 3 is laid on the guide wheel 8. After the guide wheel 8 rotates 90° to change direction, it is connected to the chandelier.

[0032] This embodiment utilizes the structure of the guide wheel 8 to guide the cable 4 to change its outgoing direction, making it suitable for both horizontal and vertical installation scenarios. This breaks the design limitations of traditional products with separate styles, eliminating the need for users to differentiate between installation environments and significantly improving product versatility.

[0033] When the chandelier moves the cable 4 up or down, the winding wheel 3 will rotate under the drive of the cable 4, and the spring winding wheel 5 will also rotate synchronously with the winding wheel 3. Therefore, the constant force spring 7 will also be wound between the spring winding wheel 5 and the spring mounting wheel 6, thus providing a stable recovery force for the chandelier.

[0034] This embodiment uses a constant force spring 7 as the core power source. By utilizing its characteristic of constant output torque throughout the entire process, the dependence on traditional gear transmission devices, torque adjustment mechanisms and friction braking devices is completely eliminated. The whole machine is composed of only core components such as the winding wheel 3, the spring winding wheel 5, the spring mounting wheel 6 and the guide wheel 8. The number of parts is reduced by more than 60%, which greatly reduces material costs and assembly complexity.

[0035] Preferably, in this embodiment, the mounting base 1 has a mounting cavity 102, and the winding wheel 3 is movably mounted in the mounting cavity 102, so that the winding wheel 3 can rotate relative to the mounting base 1. The mounting cavity 102 is connected to the wire opening 101, so that the cable 4 on the winding wheel 3 can pass through the wire opening 101. At the same time, a rotating shaft 9 is movably mounted in the wire opening 101, and a guide wheel 8 is mounted on the rotating shaft 9. The middle part of the guide wheel 8 is recessed inward to form a guide groove, so that the cable 4 can be placed on the guide wheel 8 and the guide wheel 8 can be used to change the direction of the cable exit. The setting of the guide groove can effectively prevent the cable 4 from falling off the guide wheel 8.

[0036] To facilitate the installation and removal of the mounting base 1, mounting plates 2 are installed around all four sides of the mounting base 1 in this embodiment. The mounting plates 2 can be used with the user's mounting bracket or installed independently on a wall or ceiling, offering wide applicability. The preferred structural configuration is as follows:

[0037] like Figure 6 As shown, the mounting base 1 has slots 103 around its perimeter. The mounting piece 2 has a buckle 21 on the side near the mounting base 1. The buckle 21 is inserted into the slot 103 to initially position the mounting piece 2. At the same time, a first insert rod 104 is installed in the slot 103. The buckle 21 has an insertion hole 22. The first insert rod 104 is inserted into the insertion hole 22 to further position the mounting piece 2.

[0038] The mounting base 1 is also equipped with an upper cover 10 and a lower cover 11 at both ends. The upper cover 10, the mounting base 1 and the lower cover 11 together form a take-up box. The winding wheel 3, the spring winding wheel 5 and the spring mounting wheel 6 are all located inside the take-up box.

[0039] Specifically, the mounting base 1 is preferably fixed to the upper cover 10 and the lower cover 11 in the following ways:

[0040] like Figure 5 As shown, a number of second insert rods 105 are installed on the upper end of the mounting base 1. The second insert rods 105 can be inserted into the upper cover 10, while the first insert rods 104 are inserted into the lower cover 11, thereby initially positioning the upper cover 10 and the lower cover 11. At the same time, threaded holes 12 are opened around the upper cover 10, the mounting base 1, and the lower cover 11. Fasteners are sequentially threaded into the threaded holes 12 of the three to connect the upper cover 10, the mounting base 1, and the lower cover 11.

[0041] Example 2:

[0042] This embodiment is basically the same as the chandelier in Embodiment 1, the main difference being the number of spring mounting wheels 6.

[0043] In this embodiment, a spring mounting wheel 6 is preferably used, and a constant force spring 7 is wound on the spring mounting wheel 6. One end of the constant force spring 7 is fixed on the spring winding wheel 5. A single constant force spring 7 can also provide a stable recovery force for the chandelier. This embodiment is suitable for chandeliers with smaller mass.

[0044] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
