A non-adjustable chandelier balancer

Abstract

This utility model discloses an adjustable chandelier balancer, including a mounting base, a winding wheel movably mounted within the mounting base, a cable wound on the winding wheel, a spring winding wheel mounted on one side of the winding wheel, and a spring mounting wheel movably mounted on the mounting base corresponding to the spring winding wheel. A constant force spring is wound on the spring mounting wheel, one end of which is fixed to the spring winding wheel. A gravity braking mechanism is also installed within the mounting base. When the chandelier is adjusted, the constant force spring provides a stable basic recovery force through an S-shaped winding method, while the gravity braking mechanism provides dynamically adjustable additional braking force, which is increased when pulling down and released when rising, finding a perfect balance point that matches the weight of the chandelier, thereby achieving dynamic balance throughout the entire stroke. This utility model greatly reduces the reliance on on-site fine adjustment of the spring preload, avoids the technical problems of chandelier rebound or slippage, is simple to operate, and provides consumers with a better user experience.

Description

Technical Field

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

[0002] Chandeliers are high-end decorative lighting fixtures suspended from indoor ceilings. Different users require chandeliers to hang at different heights in different usage scenarios, leading to the development of chandelier cable management boxes. These boxes allow for adjustment of the chandelier's hanging height to meet daily needs. However, existing chandelier cable management boxes typically use spiral springs. Since the elastic force of a spiral spring is proportional to its deformation, when the chandelier is at a high position, the spring force may be less than the chandelier's weight, potentially causing it to slip. Conversely, when the chandelier is at a low position, the spring force may be greater than the chandelier's weight, potentially causing it to bounce back. This makes it difficult for the spiral spring to precisely match the chandelier's weight during raising and lowering. During installation, the installer needs to repeatedly adjust the initial preload of the spring to achieve a balance of forces. The installation and adjustment process is extremely complex, heavily reliant on the installer's experience, and the balancing distance is limited, impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable chandelier balancer to address the shortcomings of the existing technology and solve the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An adjustable chandelier balancer includes a mounting base, within which a winding wheel is movably mounted. A cable is wound on the winding wheel. A spring winding wheel is mounted on one side of the winding wheel, and the spring winding wheel is integrally formed with the winding wheel. A spring mounting wheel is movably mounted on the mounting base corresponding to the position of the spring winding wheel. A constant force spring is wound on the spring mounting wheel, and one end of the constant force spring is fixed to the spring winding wheel. A gravity braking mechanism is also installed within the mounting base, and the gravity braking mechanism can abut or detach from the winding wheel.

[0006] As a preferred embodiment of an adjustable chandelier balancer, the constant force spring is stretched from one end of the spring mounting wheel to the other end of the spring winding wheel and fixedly connected thereto, so that one end of the constant force spring forms an S-shaped coiled structure.

[0007] As a preferred embodiment of an adjustable chandelier balancer, the gravity braking mechanism includes a first friction block, which is movably mounted in the mounting base via a rotating rod, allowing the first friction block to rotate relative to the rotating rod. The first friction block has a first friction angle and a second friction angle, which are set at an obtuse angle. When the first friction angle abuts against the cable, the second friction angle abuts against the winding wheel; when the first friction angle separates from the cable, the second friction angle separates from the winding wheel.

[0008] As a preferred embodiment of the adjustable chandelier balancer, the gravity braking mechanism further includes a second friction block, which is installed on one side of the end of the second friction angle, and the second friction block can abut against or separate from the side of the winding wheel.

[0009] As a preferred embodiment of an adjustable chandelier balancer, the mounting base has a mounting cavity, and the winding wheel and the first friction block are movably mounted in the mounting cavity, allowing the winding wheel and the first friction block to rotate relative to the mounting base. The bottom of the mounting base has a cable opening communicating with the mounting cavity, and the cable on the winding wheel passes through the cable opening to connect with the chandelier below.

[0010] As a preferred solution for an adjustable 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. The winding wheel, the spring winding wheel, the spring mounting wheel, and the gravity brake mechanism are all located inside the take-up box.

[0011] As a preferred embodiment of an adjustment-free chandelier balancer, the axis of the winding wheel coincides with that of the spring winding wheel.

[0012] The beneficial effects of this utility model are:

[0013] (1) The adjustable chandelier balancer of this utility model adopts a structural design with the coordinated action of constant force spring and gravity brake mechanism. When the chandelier is adjusted, the constant force spring provides a stable basic recovery force, while the gravity brake mechanism provides a dynamically adjustable additional braking force. The braking force is enhanced when pulling down and released when rising, finding the perfect balance point that matches the weight of the chandelier, thereby achieving dynamic balance throughout the entire stroke. This utility model greatly reduces the dependence on fine adjustment of the spring preload on site, avoids the technical problems of chandelier rebound or sliding, is simple and easy to operate, and brings consumers a better user experience.

[0014] (2) The constant force spring of this utility model adopts an S-shaped winding method. The S-shaped path is a symmetrical curve, which can ensure that the spring is evenly stressed during the winding and unwinding process, avoid the spring from twisting or sliding to the side, and keep the direction of the tension consistent with the direction of the pull line, thereby ensuring that the spring maintains a constant force throughout the entire process. At the same time, in the narrow space of the winding box, the S-shaped winding method can accommodate a longer constant force spring, thereby providing a longer effective working stroke to meet the needs of the chandelier for a wide range of lifting and lowering.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] like Figure 1 and Figure 2As shown, this utility model provides an adjustable chandelier balancer, including a mounting base 1. A winding wheel 2 is movably mounted inside the mounting base 1, and a cable 3 is wound on the winding wheel 2. The cable 3 passes through the mounting base 1 and connects to the chandelier below. A spring winding wheel 4 is mounted on one side of the winding wheel 2. The spring winding wheel 4 and the winding wheel 2 are preferably integrally molded, and their axes coincide, so that the spring winding wheel 4 can rotate synchronously with the winding wheel 2, and their rotation periods are the same. At the same time, a spring mounting wheel 5 is movably mounted on the mounting base 1 at the position corresponding to the spring winding wheel 4. A constant force spring 6 is wound around the chandelier 5. One end of the constant force spring 6 is fixed to the spring wheel 4. When the chandelier moves the cable 3 up or down, the winding wheel 2 will rotate under the drive of the cable 3, and the spring wheel 4 will also rotate synchronously with the winding wheel 2. Therefore, the constant force spring 6 will also be wound between the spring wheel 4 and the spring mounting wheel 5, thereby providing a stable basic recovery force for the chandelier. This greatly reduces the dependence on fine adjustment of the spring preload on site, avoids the technical problems of the chandelier rebounding or sliding down, is simple to operate, and brings a better user experience to consumers.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment, the constant force spring 6 is stretched from one end of the spring mounting wheel 5 to the other end of the spring winding wheel 4 and fixedly connected thereto. For example, it is stretched from the right end of the spring mounting wheel 5 to the left end of the spring winding wheel 4, or from the left end of the spring mounting wheel 5 to the right end of the spring winding wheel 4, so that one end of the constant force spring 6 forms an S-shaped coiled structure. The S-shaped path is a symmetrical curve, which can ensure that the constant force spring 6 maintains uniform force during the winding and unwinding process, avoids the constant force spring 6 from twisting or sliding laterally, and keeps the direction of the pulling force consistent with the direction of the pulling line, thereby ensuring that the constant force spring 6 maintains a constant force throughout the entire process. At the same time, in the narrow space of the take-up box, the S-shaped coiling method can accommodate a longer constant force spring 6, thereby providing a longer effective working stroke to meet the needs of the chandelier for a wide range of lifting and lowering.

[0030] To accommodate a wider range of chandelier weights, a gravity braking mechanism 7 can also be installed in the mounting base 1 of this embodiment. The gravity braking mechanism 7 can provide dynamically adjustable additional braking force, which is enhanced when pulled down and released when raised, to find the perfect balance point that matches the weight of the chandelier, thereby achieving dynamic balance throughout the entire stroke, so that the chandelier balancer can accommodate a wider range of chandelier weights.

[0031] like Figure 5 and Figure 6 As shown, the gravity braking mechanism 7 of this embodiment specifically includes a first friction block 71. The first friction block 71 is movably installed in the mounting base 1 through a rotating rod, so that the first friction block 71 can rotate relative to the rotating rod. The first friction block 71 has a first friction angle 711 and a second friction angle 712, wherein the first friction angle 711 and the second friction angle 712 are preferably set as an obtuse angle.

[0032] When the chandelier pulls down the cable 3, the winding wheel 2 will drive the spring winding wheel 4 to rotate synchronously. The constant force spring 6 will continuously wind from the spring mounting wheel 5 into the spring winding wheel 4, providing a basic recovery force for the cable 3 on the winding wheel 2. During this process, the cable 3 will come into contact with the first friction angle 711 and apply a downward thrust to the first friction angle 711, forcing the first friction block 71 to rotate until the second friction angle 712 comes into contact with the winding wheel 2, thereby generating friction. The second friction angle 712 will provide additional braking force to the winding wheel 2, thereby achieving dynamic balance of the chandelier at different heights.

[0033] When the chandelier moves upward, the cable 3 will be wound upward under the tension of the constant force spring 6. At this time, the constant force spring 6 will continuously wind itself back from the spring wheel 4 into the spring mounting wheel 5. Simultaneously, the cable 3 will apply an upward thrust to the first friction angle 711, forcing the first friction block 71 to rotate until the second friction angle 712 separates from the winding wheel 2, thereby releasing the additional braking force. The constant force spring 6 and the chandelier enter a new equilibrium state.

[0034] Preferably, the gravity braking mechanism 7 in this embodiment further includes a second friction block 72. The second friction block 72 is installed on one side of the end of the second friction angle 712. When the second friction angle 712 rotates, the second friction block 72 will rotate synchronously with it. The second friction block 72 can increase the contact area with the winding wheel 2 and provide a greater additional braking force for the gravity braking mechanism 7.

[0035] Specifically, in this embodiment, the mounting base 1 has a mounting cavity 11, and the winding wheel 2 and the first friction block 71 are movably mounted in the mounting cavity 11, so that the winding wheel 2 and the first friction block 71 can rotate relative to the mounting base 1. The bottom of the mounting base 1 has a wire opening 12 that communicates with the mounting cavity 11. The cable 3 on the winding wheel 2 passes through the wire opening 12 and connects to the chandelier below. The first friction angle 711 is located near the wire opening 12, so that it can abut against the cable 3.

[0036] Meanwhile, the upper cover 8 and the lower cover 9 are respectively installed at both ends of the mounting base 1. The upper cover 8, the mounting base 1 and the lower cover 9 together form the take-up box. The winding wheel 2, the spring winding wheel 4, the spring mounting wheel 5 and the gravity brake mechanism 7 are all located inside the take-up box.

[0037] 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.
