Description

Technical Field

[0001] The present application relates to the field of lighting technology, and more particularly to the field of lampshade suspension technology. Background Art

[0002] In modern interior decoration and lighting design, blown glass is widely used in lamp manufacturing due to its unique aesthetic and light-transmitting properties. However, the uneven glass wall thickness and resulting weight distribution caused by the blown glass process pose challenges to lampshade installation. This can cause the lampshade to tilt after installation, compromising the overall aesthetics and safety of the lamp.

[0003] Therefore, for lampshades such as blown glass, which have the risk of tilting due to uneven weight distribution when installed, there is a demand for a hanging device that is easy to disassemble and assemble. It can be used for rapid inspection before leaving the factory or for non-destructive replacement in application scenarios where frequent replacement is required. Utility Model Content

[0004] In response to the above-mentioned needs, the present application proposes a lampshade hanging device, which enables the lampshade to be quickly connected and separated from the hanging device, thereby ensuring the safe and stable installation of the lampshade and the visual harmony after installation.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] A lampshade hanging device comprises a hollow column with a hollow ring, wherein the outer periphery of the hollow column is provided with a plurality of fixing clips capable of limiting the upward movement of the lampshade;

[0007] A rotating clamp, rotating relative to the fixed clamp and clamping the edge of the lampshade together with the fixed clamp;

[0008] The pushing device is in the shape of a cone that narrows upwards, and pushes the rotating clamp when moving upwards, causing it to rotate relative to the fixed clamp;

[0009] The pushing device includes a pushing portion for pushing the rotating clamp and a guide column moving in the hollow ring. The outer diameter of the pushing portion is smaller than the outer diameter of the fixed clamp. The top of the guide column is higher than the hollow column in the clamping state.

[0010] This application allows users to easily adjust the position of the swivel clamp by simply pushing the push mechanism up and down, thereby achieving precise centering and secure fixation of the lampshade. This reduces the complexity of manual operation and the time and cost of replacement, and effectively avoids the risk of damage to the lampshade caused by manual squeezing. In addition, because the swivel clamp can automatically reset, it further ensures the safety and reliability of the lampshade during installation and removal.

[0011] In some feasible embodiments, the pushing device is provided with a stop step at the joint with the hollow column, facilitating control of the pushing stroke, preventing the conical pushing device from being pushed with interference with the hollow column, and facilitating removal.

[0012] In some preferred embodiments, the rotating clamp is provided with a hook claw part at the lower end. When the hook claw part is designed, the force points are uniformly distributed when the lampshade rim is clamped, improving the detection accuracy.

[0013] In some preferred embodiments, the upper end of the rotating clamp is provided with a counterweight protruding part, so that the rotating clamp is in a state of shrinking inward when it is naturally vertical.

[0014] In some feasible embodiments, the upper end of the hollow column is provided with a guide sleeve, which can stabilize the displacement of the pushing device, facilitate the installation of lampshade detection devices and other accessories, and reduce the influence of these accessories on the hollow column.

[0015] In some preferred embodiments, the outer diameter of the pushing part of the pushing device is smaller than the inner diameter of the fixed clamp, so that the stroke of the pushing part can extend to the inner circle of the fixed clamp, improving the compatibility of clamping lampshades.

[0016] In some preferred embodiments, each rotating clamp corresponds to two fixed clamps, which are respectively arranged on the left and right sides of the rotating clamp, improving the clamping stability.

[0017] In some preferred embodiments, the rotating clamp is 4.

[0018] In some feasible embodiments, the inner circle of the fixed clamp is provided with an inner circle extension part extending to the inner circle of the lampshade rim, which can prevent the lampshade from falling off due to tilting, improving the stability and reliability.

[0019] In some preferred embodiments, the periphery of the fixed clamp is provided with a downward outer circle extension part, and the outer circle extension part and the inner circle extension part form a clamping gap, which can effectively position the lampshade rim with a flange.

[0029] The following examples further illustrate the features of the present application and other related features to facilitate understanding by those skilled in the art:

[0030] It should be noted that the words "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0031] First, using blown glass as an example, we'll explain how uneven weight distribution can cause a tilted lampshade when installed. When blown glass is formed into a thin lampshade, its surface area is relatively large. This is significantly affected by factors such as raw material distribution, mold design, temperature control, and blowing pressure. This results in uneven weight distribution throughout the entire lampshade, leading to imbalance.

[0032] For the application working status of blow molded lampshade, please refer to Figure 9 , the lampshade 1 is in a state of being suspended by the hanging rope 2, that is, the overall weight of the lampshade is balanced. At this time, if the weight of the lampshade 1 is uneven, it will cause it to tilt after being hung. Therefore, during production, a suspension device that can quickly simulate the application of the suspension state is required to quickly complete the balance test. Moreover, this rapid detection simulation device is also suitable for conventional installation methods, especially in scenarios where the lampshade or lighting source needs to be frequently replaced (such as celebrations).

[0033] It should be noted that the blown glass lampshade is an application example, and lampshades made by other processes are also suitable for a lampshade hanging device of the present application. The present application is not limited to blown glass lampshades.

[0034] Please refer to Figures 1 to 3The lampshade hanging device of the present application includes a hollow column 100, and a plurality of fixing clips 110 are provided on the outer periphery of the hollow column 100. The fixing clips 110 are used to limit the upward movement of the lampshade at the upper end. Specifically, the fixing clips 110 can be formed integrally with the hollow column 100, or can be added later. For the specific structure, please refer to Figure 4 The hollow column 100 is provided with a hollow ring 120 in the center thereof, and the fixing clips 110 are evenly distributed on the periphery, preferably 4 in number. In the figure, the hollow ring 120 is circular, but it can be other stable shapes such as a quadrangle.

[0035] Please refer to Figure 1 、 Figure 3 、 Figure 8 , a rotating clamp 200 is provided correspondingly thereto. The rotating clamp 200 rotates relative to the fixed clamp 110 and clamps the edge 11 of the lampshade 1 together with the fixed clamp 110 at the lower end. In specific implementation, the rotating method can be to rotate through the rotating shaft 3. For the specific form of the rotating clamp 200, please refer to Figure 5 It is preferred to provide fixed clamps 110 on the left and right sides of the rotating clamp 200, that is, each rotating clamp 200 corresponds to two fixed clamps 110, to improve the clamping stability.

[0036] In some preferred embodiments of the rotary clamp 200, a hook portion 210 is provided at the lower end of the rotary clamp 200. Figure 8 During use, the thickness of the lampshade 1 is not always uniform. In this case, if the clamping portion of the rotating clamp 200 is always flat, the contact point with the edge 11 of the lampshade 1 will change each time, resulting in uneven force and poor versatility. Therefore, the design of the claw 210 can evenly distribute the force points when clamping the edge 11 of the lampshade 1, thereby improving detection accuracy.

[0037] Please refer to Figure 2 and Figure 5 A counterweight protrusion 220 is provided at the upper end of the rotating clamp 200, which can make the rotating clamp 200 shrink toward the inner circle when it is naturally vertical. Figure 2 , which is on the inner side of the fixing clamp 110, so when replacing a new lampshade 1, there is no need to operate the rotating clamp 200, and it can be directly inserted. Here, further, an inclined guide part 230 is provided at the lower end of the rotating clamp 200. When the lampshade 1 is inserted, the guide part 230 is inclined, so it will not get stuck on the lampshade 1, but will rotate inward accordingly.

[0038] Please refer to Figure 4 and Figure 6 、 Figure 8Corresponding to the rotating clamp 200 described above, the inner ring of the fixing clamp 110 is provided with inner ring extensions 111 extending to the inner ring of the rim 11 of the lampshade 1. In a preferred embodiment of the present application, there are four groups of eight extensions 111 distributed inside the rim 11, which can prevent the lampshade 1 from tilting and falling off, thereby improving stability and reliability.

[0039] A downward-pointing outer extension 112 is provided on the periphery of the fixing clip 110. A clamping gap 113 is formed between the outer extension 112 and the inner extension 111, effectively positioning the rim 11 of the lampshade 1 with the flange 12. Specifically, in practice, the outer extension 112 is shorter than the inner extension 111, creating a lever-like balance between the outer extension 112 and the hook 210, which applies upward and downward force to the rim 11.

[0040] Please refer to Figures 1 to 3 As a driving device for rotating the rotating clamp 200 and clamping the lampshade 1, a pushing device 300 is provided. It is a tapered structure that narrows upward, and pushes the rotating clamp 200 to rotate relative to the fixed clamp 110 when moving upward.

[0041] Specifically, the pressing device 300 includes a pressing portion 310, or a tapered portion, for pressing the rotating clamp 200. A conical shape is preferred for its versatility. If the number of fixed clamps 110 is fixed, the tapered shape can also be adapted to suit the application. The device also includes a guide post 320 that moves within the hollow ring 120, with the hollow ring 120 acting as a guide. Therefore, when clamped, the guide post 320 protrudes above the hollow post 100.

[0042] At this time, at least the outer diameter of the pushing portion 310 is smaller than the outer diameter of the fixing clamp 110 , so that after the pushing portion 310 pushes the rotating clamp 200 , there is space between the rotating clamp 200 and the fixing clamp 110 to clamp the lampshade 1 .

[0043] Preferably, the outer diameter of the pushing portion 310 is smaller than the inner diameter of the fixing clamp 110 , so that the stroke of the pushing portion 310 can extend to the inner circle of the fixing clamp 110 , thereby improving the compatibility of clamping the lampshade 1 .

[0044] This design allows the user to easily adjust the position of the rotating clamp 200 by simply pushing the pushing device 300 up and down, thereby achieving accurate centering and firm fixation of the lampshade 1.

[0045] This reduces the complexity of manual operation and the time cost of replacement, and effectively avoids the risk of damage to the lampshade 1 caused by manual squeezing. In addition, since the rotating clamp 200 can automatically reset under its own weight, the safety and reliability of the lampshade 1 during installation and removal are further guaranteed.

[0046] Please refer to Figure 3 and Figure 4 As mentioned above, manual manipulation is required during operation, and the upper end is in a suspended state. Therefore, after being suspended, the pressing portion 310 will be subjected to the weight of the lampshade 1. If it remains in a tapered shape, it will be excessively squeezed, resulting in interference between the pressing device and the hollow column, making manual removal inconvenient. Therefore, a stop step 311 is provided at the junction of the pressing portion 310 of the pressing device 300 and the hollow column 100 to facilitate control of the pressing stroke while also preventing interference.

[0047] Please refer to Figure 2 In some embodiments, a guide sleeve 130 can be provided at the upper end of the hollow column 100 to stabilize the displacement of the pushing device 300 while facilitating the installation of accessories such as a lampshade 1 detection device and reducing the impact of these accessories on the hollow column 100. The detection device can be a balance board for testing balance, and can also be provided with a decorative plate when in use, that is, there is an installation operation at the upper end.

[0048] As mentioned above, this case protects a lampshade hanging device, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
