Description

Technical Field

[0001] This utility model relates to the field of chandelier technology, specifically to a connecting component for a chandelier shade. Background Technology

[0002] In the daily use and maintenance of chandeliers, the ease of disassembling and installing the lampshade has always been a key issue affecting user experience. Traditional chandeliers often rely on a single snap-fit ​​structure to directly attach the lampshade to the lamp body. While this can achieve initial fixation, the disassembly process is often extremely cumbersome when cleaning the lampshade, replacing the bulb, or inspecting internal components later.

[0003] Specifically, existing snap-fit ​​designs are mostly rigid connections, requiring tools or manual force to pry them open during disassembly. This is not only laborious but also prone to deformation and breakage due to repeated stress, potentially damaging the entire lampshade and significantly shortening the lamp's lifespan. For chandeliers with specific shapes, such as columnar ones, the snap-fit ​​locations are often hidden due to their compact structure, making disassembly even more difficult and increasing maintenance challenges. Furthermore, while some improved solutions attempt to use threaded connections or magnetic structures, threaded connections are prone to jamming due to oxidation and dust accumulation after prolonged use, requiring precise alignment during disassembly. Magnetic structures, on the other hand, are limited by the stability of their magnetic force and are prone to detachment upon vibration or external force, making it difficult to balance connection reliability with ease of disassembly.

[0004] Chinese Patent Publication No. CN223153428U discloses a connection structure for a chandelier shade. The structure includes a detachable connection mechanism between the lamp body and the shade. This mechanism comprises an annular groove at the bottom of the lamp body, a latching component on the outside of the shade that engages with the annular groove, and an elastic locking component on the lamp body. The lamp body also has an opening groove on the lamp body that connects the annular groove to the outside. This allows the shade to be detachably and securely connected to the lamp body. Unlocking is achieved by simply pushing the elastic locking component, making the shade easy to remove and less prone to damage. However, the main load-bearing capacity of this structure relies on the engagement of the lamp body's protrusion with the latching component's groove. Since this is a single-point contact (or small-area contact), if the shade is heavy or used for a long period, stress concentration at the contact point between the protrusion and the groove can cause wear and loosening of the connection.

[0005] Therefore, there is a lack of a connection structure in the existing technology that can both ensure a stable connection between the lampshade and the lamp body and enable quick and non-destructive disassembly during maintenance. This problem is particularly prominent in scenarios such as homes and commercial venues where chandelier maintenance is frequent. Utility Model Content

[0006] To address the aforementioned issues, a connecting component for chandelier shades is provided. By setting up a connecting mechanism, a stable connection between the lamp body and the connecting mechanism is ensured, while also facilitating the later disassembly of the lamp body for maintenance. This solves the problem of the cumbersome disassembly and assembly of the connecting mechanism on the traditional lamp body.

[0007] To address the problems of existing technologies, this utility model provides a connecting assembly for a chandelier shade, including a connecting mechanism for connecting the lamp body to the ceiling of a building chandelier. The connecting mechanism includes a first connecting pipe, a second connecting pipe, and a connecting box. One end of the first connecting pipe is connected to the lamp body, and the other end is detachably connected to the connecting box. One end of the second connecting pipe is connected to the connecting box, and the other end is connected to the ceiling of the building chandelier. The wires inside the lamp body can pass through the connecting mechanism and connect to the power junction box inside the ceiling of the building.

[0008] Preferably, the connecting box includes a box body with an operating hole that runs vertically through it and a support block that moves radially along the operating hole. A top block is provided on the top of the first connecting tube, and a sliding block that can move axially along the first connecting tube is sleeved on the outer wall of the first connecting tube. Moving the first connecting tube can cause the top block or the sliding block to contact the support block.

[0009] Preferably, the connecting box further includes radial through holes and springs. A plurality of radial through holes are evenly distributed radially along the operating hole. The support block includes a bearing block, a moving rod, and a limiting member. One end of the bearing block is fixed to the moving rod. The limiting member is detachably connected to the moving rod and is disposed on the outside of the connecting box. The spring is sleeved on the moving rod and its ends respectively contact the bearing block and the connecting box.

[0010] Preferably, the connecting box further includes a connecting plate, which is disposed at the radial through hole on the outer wall of the connecting box. The connecting plate is provided with a movable hole, and the moving rod can move within the movable hole.

[0011] Preferably, the top block is fixed to the top of the first connecting pipe, the orthographic projection of the upper edge of the sliding block coincides with the orthographic projection of the lower edge of the top block, and the end of the bearing block extending into the operating hole is provided with a cut, so that the top block and the sliding block can contact the cut and drive the bearing block to move in the radial through hole.

[0012] Preferably, the wires inside the lamp body can pass through the first connecting pipe, the operating hole, and the second connecting pipe to connect to the power junction box inside the ceiling of the building chandelier.

[0013] Preferably, a middle plate is provided at the top of the lamp body, and the lower end of the first connecting tube is detachably connected to the middle plate.

[0014] Preferably, the bottom of the second connecting tube is detachably connected to the top of the connecting box.

[0016] The connecting mechanism, as the core component, consists of three parts: the first connecting pipe, the second connecting pipe, and the connecting box. Each component has a clear division of labor and works together. This design not only ensures a stable connection between the lamp body and the connecting mechanism, but also provides convenience for disassembling the lamp body for maintenance later. The second connecting pipe plays a connecting role, with one end connected to the connecting box and the other end directly fixed to the ceiling of the building. It becomes a load-bearing bridge between the connecting mechanism and the building structure, ensuring the installation stability of the entire chandelier system. Attached Figure Description

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figures 1-6 As shown, this utility model provides a connecting assembly for a chandelier shade, including a connecting mechanism 2. The connecting mechanism 2 is used to connect the lamp body 1 to the ceiling of the building chandelier. The connecting mechanism 2 includes a first connecting pipe 20, a second connecting pipe 21, and a connecting box 22. One end of the first connecting pipe 20 is connected to the lamp body 1, and the other end is detachably connected to the connecting box 22. One end of the second connecting pipe 21 is connected to the connecting box 22, and the other end is connected to the ceiling of the building chandelier. The wires inside the lamp body 1 can pass through the connecting mechanism 2 and be connected to the power junction box inside the ceiling of the building.

[0026] The connecting mechanism 2, as the core component, is specifically composed of three parts: the first connecting pipe 20, the second connecting pipe 21, and the connecting box 22. Each component has a clear division of labor and works in concert: one end of the first connecting pipe 20 is fixedly connected to the lamp body 1, and the other end is assembled in the connecting box 22 in a detachable manner (such as threaded connection, snap-fit, etc.). This design not only ensures the stable connection between the lamp body 1 and the connecting mechanism 2, but also provides convenience for the later disassembly of the lamp body 1 for maintenance (such as replacing the bulb or cleaning the lampshade); the second connecting pipe 21 plays a connecting role, with one end connected to the connecting box 22 and the other end directly fixed to the ceiling of the building, becoming a load-bearing bridge between the connecting mechanism 2 and the building structure, ensuring the installation stability of the entire chandelier system.

[0027] Furthermore, the connecting component fully considers the wiring requirements: the wires inside the lamp body 1 can run through the internal channels of the first connecting pipe 20, the connecting box 22, and the second connecting pipe 21, passing through the entire connecting mechanism 2, and finally connecting to the power junction box pre-installed in the ceiling of the building. This concealed wiring design not only avoids the problem of wires being exposed to the air and corroded by dust and moisture, reducing safety hazards, but also maintains the overall aesthetics of the chandelier, allowing the connecting component to meet both practical and aesthetic needs while fulfilling its structural function.

[0028] The connecting box 22 includes a box body 220 with an operating hole 2200 that runs vertically through it and a support block 221 that moves radially along the operating hole 2200. A top block 200 is provided on the top of the first connecting tube 20. A sliding block 201 that can move axially along the first connecting tube 20 is sleeved on the outer wall of the first connecting tube 20. Moving the first connecting tube 20 can cause the top block 200 or the sliding block 201 to contact the support block 221.

[0029] When it is necessary to install or fix the lamp body 1, by moving the first connecting tube 20 axially along the operating hole 2200, the top block 200 can contact the support block 221. The top block 200 generates a radial thrust on the support block 221, causing the support block 221 to extend outward from the operating hole 2200 and abut against the inner wall of the connecting box 22 or the second connecting tube 21, forming a locked state, thereby firmly restricting the first connecting tube 20 within the connecting box 22. When it is necessary to disassemble the lamp body 1, by continuing to move the first connecting tube 20, the sliding block 201 contacts the support block 221. The sliding block 201 generates a reverse thrust on the support block 221, forcing the support block 221 to retract radially. This quickly moves the first connecting tube 20 downward, releasing the locking of the first connecting tube 20 by the connecting box 22. At this time, the first connecting tube 20 can be pulled out of the connecting box 22, realizing the convenient disassembly of the lamp body 1. This design, which achieves locking and unlocking through the contact and cooperation of the top block 200, the sliding block 201 and the support block 221, not only ensures the structural stability of the lamp body 1 after installation, but also simplifies the operation process during later maintenance, fully demonstrating the synergy and practicality of the connecting components in the mechanical structure design.

[0030] The connecting box 22 also includes a radial through hole 2201 and a spring 222. Several radial through holes 2201 are evenly distributed radially along the operating hole 2200. The support block 221 includes a bearing block 2210, a moving rod 2211 and a limiting member 2212. One end of the bearing block 2210 is fixed with the moving rod 2211. The limiting member 2212 is detachably connected to the moving rod 2211. The limiting member 2212 is located on the outside of the connecting box 22. The spring 222 is sleeved on the moving rod 2211 and its ends respectively contact the bearing block 2210 and the connecting box 22.

[0031] Based on the original operating hole 2200 and support block 221, the connecting box 22 has added a radial through hole 2201 and a spring 222, which further improves the functionality and stability of the locking mechanism. The radial through hole 2201 provides precise guidance for the movement of the support block 221. The bearing block 2210 is a force-bearing component that directly contacts the top block 200 or sliding block 201 on the first connecting pipe 20. Its shape is adapted to the inner wall of the operating hole 2200 to ensure stability during contact. One end of the moving rod 2211 is fixedly connected to the bearing block 2210, and the other end extends through the radial through hole 2201 to the outside of the connecting box 22, becoming the "skeleton" for the radial movement of the support block 221. The limiting member 2212 is installed on the outer end of the moving rod 2211 in a detachable manner (such as threaded connection, pin fixing, etc.). Its size is larger than the diameter of the radial through hole 2201, which can effectively limit the maximum retraction of the support block 221 and prevent the support block 221 from detaching from the connecting box 22 due to excessive movement. At the same time, it is convenient to inspect and replace the support block 221 or spring 222 later. The addition of spring 222 provides the support block 221 with the power for automatic reset, forming a stable and reliable mechanical linkage mechanism. This ensures the rigid support of the first connecting tube 20 when locked and realizes automatic reset after unlocking, greatly improving the ease of operation and structural durability of the connecting components.

[0032] The connecting box 22 also includes a connecting plate 223, which is disposed at the radial through hole 2201 on the outer wall of the connecting box 22. The connecting plate 223 is provided with a movable hole 2230, and the moving rod 2211 can move within the movable hole 2230. The setting of the connecting plate 223 makes it easier to replace the support block 221 and spring 222 in the connecting box 22, which is beneficial for later maintenance.

[0033] The top block 200 is fixed to the top of the first connecting pipe 20. The orthographic projection of the upper edge of the sliding block 201 coincides with the orthographic projection of the lower edge of the top block 200. The bearing block 2210 extends into one end of the operating hole 2200 and has a notch. The top block 200 and the sliding block 201 can contact the notch to drive the bearing block 2210 to move in the radial through hole 2201. Figures 3-4 As shown, the cut, as a clearly defined force-bearing area, can guide the top block 200 and the sliding block 201 to make precise contact and apply thrust, avoiding the problems of "empty push" or "insufficient force transmission" caused by ambiguous contact position, ensuring that the bearing block 2210 can move as expected along the radial through hole 2201, thereby ensuring the reliable execution of the locking / unlocking action of the support block 221.

[0034] The wires inside the lamp body 1 can pass through the first connecting pipe 20, the operating hole 2200, and the second connecting pipe 21 to connect to the power junction box inside the ceiling of the building chandelier.

[0035] A middle plate 10 is provided at the top of the lamp body 1, and the lower end of the first connecting pipe 20 is detachably connected to the middle plate 10. For example... Figures 5-6 As shown, the intermediate plate 10 is detachably connected to the lamp body 1. The first connecting tube 20 is connected to the intermediate plate 10 to increase the adaptability of the installation. Preferably, an oblong hole is provided on the intermediate plate 10 to facilitate the adjustment of the positional relationship between the lamp body 1 and the connecting mechanism 2.

[0036] The bottom of the second connecting pipe 21 is detachably connected to the top of the connecting box 22. For example... Figure 2 As shown, the bottom of the second connecting pipe is connected to the top of the connecting box 22 via a flange, making the connection between the two more stable.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
