[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a technical solution:

[0033] A lampshade mainly consists of a mounting base 1, an auxiliary section 2, a first connecting rod 3, a second connecting rod 5, a sliding body 4, an adjusting ring 7, and a lampshade cloth 6.

[0034] Mounting base 1, serving as the basic support for the entire lampshade, is manufactured using a one-piece injection molding process. One end of it is detachably equipped with an auxiliary section 2. Several first rotating seats 10 are also fixedly mounted on mounting base 1, these first rotating seats 10 being evenly distributed in a circular array on mounting base 1. The first connecting rod 3 is rotatably mounted on the first rotating seat 10 via a first rotating shaft 11. This connection method allows the first connecting rod 3 to rotate flexibly on mounting base 1 to adjust its angle.

[0035] A slider 4 is slidably mounted on the auxiliary section 2. The outer diameter of the auxiliary section 2 and the mounting base 1 are the same, ensuring that the slider 4 can slide smoothly between the auxiliary section 2 and the mounting base 1. Several second rotating seats 12 are fixedly mounted on the slider 4, also distributed in a circular array. The second connecting rod 5 is rotatably mounted on the second rotating seat 12 via the second rotating shaft 13, allowing the second connecting rod 5 to rotate freely on the slider 4. A third rotating seat 14 is fixedly mounted on the first connecting rod 3, and a third rotating shaft 15 is fixedly mounted on one end of the second connecting rod 5, rotatably mounted in the third rotating seat 14. In this way, the first connecting rod 3, the second connecting rod 5, and the slider 4 form a crank-slider mechanism.

[0036] The mounting base 1 is also fixedly provided with several clips 8, which are wedge-shaped and distributed in a circumferential array on the mounting base 1. These clips 8 limit the sliding body 4 after the lamp cover is unfolded.

[0037] The top of the mounting base 1 is provided with several adjustable rings 7 in a detachable manner, and these adjustable rings 7 are coaxially arranged with the mounting base 1.

[0038] A lampshade cloth 6 is fixedly installed on several first connecting rods 3. The lampshade cloth 6 plays a crucial role in the entire lampshade. It not only has the effect of shading light, effectively blocking excess light scattering and avoiding light pollution and glare, but also has the function of diffused light, so that the light can be more evenly distributed in the surrounding environment, creating a comfortable and soft lighting atmosphere.

[0039] One side of the lampshade cloth 6 is provided with a reflective material, which can greatly enhance the reflection effect of light, thereby significantly improving the lighting brightness.

[0040] The reflective material can be a special metallic coating, such as an aluminum foil coating. Aluminum has excellent reflective properties, and when it is applied as a coating to the surface of the lampshade fabric 6, it can efficiently reflect light. When light shines on the lampshade fabric 6 with the aluminum foil coating, the aluminum foil reflects the light at a specific angle, making the light more concentrated and thus improving the lighting brightness.

[0041] Reflective materials can also be coatings containing tiny glass beads. These beads can reflect and refract incident light multiple times, greatly improving the reflective effect. The size and density of the glass beads can be adjusted according to actual needs to achieve optimal reflective performance.

[0042] In the transport and storage state, such as Figure 2 and Figure 3 As shown, the auxiliary section 2 is connected to the mounting base 1, serving to support the entire device. At this time, the sliding body 4 is positioned away from the mounting base 1, and the angle between the first connecting rod 3 and the mounting base 1 is minimal. This configuration prevents deformation of components such as the first connecting rod 3 during transportation due to compression.

[0043] When the lampshade needs to be unfolded, the operator pushes the slider 4, causing it to move from the auxiliary section 2 towards the mounting base 1. Since the slider 4, the first connecting rod 3, and the second connecting rod 5 form a crank-slider mechanism, the slider 4, during its movement, drives the first connecting rod 3 to rotate around the mounting base 1 via the second connecting rod 5. At this time, the angle between the first connecting rod 3 and the mounting base 1 increases, and the lampshade cloth 6 on the first connecting rod 3 gradually unfolds. Continuing to push the slider 4... Figure 5 As shown, the sliding body 4 extends above the wedge-shaped buckle 8, which limits the sliding body 4 and prevents it from sliding accidentally. After the lampshade cloth 6 is unfolded, as... Figure 1 and Figure 4 As shown, the operator removes auxiliary section 2 from mounting base 1.

[0044] The operator then installs the device between the bulb and the lamp holder using mounting bracket 1. During use, the reflective material of the lampshade cloth 6 reflects the light, improving the lighting effect.

[0045] Example 2:

[0046] In this embodiment, as Figure 3 As shown, several connecting posts 9 are fixedly arranged between the auxiliary section 2 and the mounting base 1. These connecting posts 9 play a crucial connecting role, tightly connecting the auxiliary section 2 and the mounting base 1 together. The auxiliary section 2 is fixedly connected to the mounting base 1 through these connecting posts 9.

[0047] Auxiliary section 2, mounting base 1, and connecting column 9 are manufactured using a one-piece injection molding process. During production, the material used to make these three components is injected into a specific mold. Under high temperature and pressure, the material fills the entire mold cavity, and after cooling, it forms a complete unit. This one-piece injection molding method makes the connection between auxiliary section 2, mounting base 1, and connecting column 9 extremely strong, eliminating problems such as gaps and loosening that may occur with traditional connection methods.

[0048] After the lampshade cloth 6 is unfolded, the operator breaks the connecting post 9 with external force to facilitate subsequent operations. The auxiliary section 2 is then removed from the mounting base 1. The operator can use appropriate tools, such as pliers, to apply a certain amount of external force to the connecting post 9. The connecting post 9 will break under the external force, thus separating the auxiliary section 2 from the mounting base 1.

[0049] Before the lampshade fabric 6 is unfolded, the auxiliary section 2 is connected to the mounting base 1 via the connecting post 9, providing stable support for the unfolding process (i.e., the sliding of the sliding body 4). After the lampshade fabric 6 is unfolded, the auxiliary section 2 needs to be removed for better subsequent installation operations. By injection molding the auxiliary section 2, mounting base 1, and connecting post 9 into a single unit, stability during the unfolding process is ensured, and the connecting post 9 can be broken by external force when necessary, allowing for convenient removal of the auxiliary section 2. This creates favorable conditions for fixing the mounting base 1 between the bulb and the lamp holder.

[0050] Example 3:

[0051] In this embodiment, as Figure 7 As shown, one end of the auxiliary section 2 has an external thread, and the mounting base 1 has an internal thread. The internal thread matches the external thread, and the auxiliary section 2 is mounted on the mounting base 1 via the external thread. To remove the auxiliary section 2, simply loosen the thread.

[0052] Example 4:

[0053] Considering the diversity of light bulb models and sizes on the market, this embodiment employs a method to better accommodate light bulbs and sockets of different sizes, such as... Figure 6 As shown, a detachable adjustment ring 7 is provided in this embodiment.

[0054] When dealing with bulb and socket combinations of different sizes, operators can remove different numbers of adjusting rings 7 depending on the actual situation. If the bulb and socket are large, more adjusting rings 7 can be removed to ensure the lampshade can be tightly installed between the bulb and socket. Conversely, if the bulb and socket are small, more adjusting rings 7 can be retained to ensure the lampshade fully covers the gap between the bulb and socket.

[0055] Several adjusting rings 7 are fixedly connected by several connecting rods. These connecting rods serve to reinforce and stabilize the structure of the adjusting rings 7. The connecting rods, adjusting rings 7, and mounting base 1 are integrally molded by injection molding.

[0056] In practice, when it is necessary to disassemble the adjusting ring 7, simply break the connecting rod that connects to the corresponding adjusting ring 7. This design not only facilitates flexible adjustments by operators according to different bulb and lamp holder sizes, but also ensures the stability and reliability of the lampshade during use.

[0057] It should be noted that the number and size of different adjustment rings 7 can be manufactured according to actual conditions, and no specific limitation is made in this patent.

[0058] Working principle: During use, such as in the transportation and storage state, this utility model... Figure 2 and Figure 3 As shown, the auxiliary section 2 is connected to the mounting base 1, providing support for the entire device and preventing components such as the first connecting rod 3 from deforming due to compression during transportation. At this time, the sliding body 4 is located away from the mounting base 1, the angle between the first connecting rod 3 and the mounting base 1 is minimal, and the entire device is in a compact state, facilitating transportation and storage.

[0059] When the lampshade needs to be unfolded, the operator first pushes the slider 4, moving it from the auxiliary section 2 towards the mounting base 1. Since the auxiliary section 2 and the mounting base 1 have the same outer diameter, the slider 4 can slide smoothly between them. The slider 4, the first connecting rod 3, and the second connecting rod 5 form a crank-slider mechanism. As the slider 4 moves, the second connecting rod 5 drives the first connecting rod 3 to rotate around the mounting base 1. During this process, the angle between the first connecting rod 3 and the mounting base 1 gradually increases, and the lampshade cloth 6 fixed on the first connecting rod 3 gradually unfolds. Continuing to push the slider 4 past the wedge-shaped buckle 8, the wedge-shaped buckle 8 limits the slider 4, preventing accidental sliding and ensuring the lampshade remains stable in the unfolded state. After the lampshade cloth 6 is unfolded, as... Figure 1 and Figure 4 As shown, the operator removes the auxiliary section 2 from the mounting base 1 so that the device can be installed between the bulb and the lamp holder via the mounting base 1.

[0060] During use, the reflective material on one side of the lampshade cloth 6 can efficiently reflect light, improve lighting brightness, and make the light more concentrated in a specific direction, creating a bright and comfortable lighting environment.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
