[0042] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments.
[0043] [Example]
[0044] Combination Figure 1As shown, an outdoor lampshade connection structure of this embodiment includes a base 1 and a lampshade 2 invertedly mounted on the base 1. It also includes a waterproof strip 3, connecting fasteners 4, and fasteners 5. The waterproof strip 3 is installed on the side of the base 1 and has a bottom plate 3-1 and an inner baffle 3-2. The side wall 2-1 of the lampshade 2 covers the outside of the inner baffle 3-2 of the waterproof strip 3, such that the gap between the side wall 2-1 and the inner baffle 3-2 is located inside the lampshade 2. To prevent water from seeping into the inside of the lampshade through gaps, the lampshade 2 has several hanging holes 2-2 spaced apart on its side wall 2-1. One side of the connecting fastener 4 has a buckle 4-1, which connects to the corresponding hanging hole 2-2 of the lampshade 2 via the buckle 4-1. Fasteners 5 pass through the base plate 3-1 of the base 1 and the waterproof strip 3 in sequence and are then locked to the connecting fastener 4, thus achieving the sequential connection and fixation of the base 1, waterproof strip 3, connecting fastener 4, and lampshade 2. This outdoor lampshade connection structure, by setting a waterproof strip 3 between the lampshade 2 and the base 1, and using connecting fasteners 4 that are inserted around the lampshade 2 as the connection components to the base 1, solves the connection problem between the thin-walled lampshade 2 and the base 1, greatly improving the connection strength of the thin-walled lampshade. Simultaneously, the waterproof strip 3 enhances the waterproofness of the connection area. It has advantages such as convenient and quick installation, high connection strength, good waterproof effect, low production cost, and no impact on the aesthetics of the outdoor lamp.
[0045] Reference Figure 4 , Figure 5 and Figure 9 As shown, in this embodiment, the buckle 4-1 is an upward-turned "L" shape, and the hanging hole 2-2 is a strip-shaped hole. The buckle 4-1 is inserted into the hanging hole 2-2 and engages with it. In this way, only a hole needs to be made on the side wall 2-1 of the lampshade 2, making the manufacture of the lampshade 2 more convenient. The upward-turned buckle 4-1 not only makes the installation of the lampshade 2 easier and more convenient, but also improves the reliability of the connection with the hanging hole 2-2, effectively preventing the two from loosening, and preventing the side wall 2-1 of the lampshade 2 from deforming inward, thus improving the assembly effect.
[0046] like Figures 1 to 3 As shown, in this embodiment, the base 1 also has side baffles 1-1 around its perimeter, and the bottom plate 3-1 of the waterproof strip 3 also has an outer baffle 3-3 on one side. The outer baffle 3-3, the inner baffle 3-2, and the bottom plate 3-1 form a water guide groove 3a. The cross-sectional shape of the water guide groove 3a is U-shaped. The bottom plate 3-1 also has a drain hole 3b, and the base 1 is also provided with an external drain hole 1-2 opposite to the position of the drain hole 3b. Preferably, the size of the external drain hole 1-2 is larger than the size of the drain hole 3b, which can prevent water from seeping between the base 1 and the waterproof strip 3 during drainage. For example, the drain hole 3b can be made of... Figure 2 The small round holes shown, and the outer holes 1-2, can be made as follows: Figure 1The elongated, waist-shaped hole shown has drainage holes 3b corresponding to it, both located inside the hole. During drainage, water inside the waterproof strip 3 can be directly discharged through drainage holes 3b, preventing it from seeping into the gap between the base 1 and the waterproof strip 3. To further improve waterproofing, waterproof adhesive is used to seal the gap between the base 1 and the waterproof strip 3. The side baffle 1-1 wraps around the lampshade 2 and positions the waterproof strip 3 during connection, facilitating assembly and positioning of various parts. The water channel 3a formed by the waterproof strip 3 collects water and drains it through the drainage holes 3b, preventing water accumulation and providing good waterproofing. Figure 3 As shown, the outer baffle 3-3 further has an outer flange 3-4 that can be interlocked with the corresponding side baffle 1-1 of the base 1. The outer flange 3-4 is in an inverted "L" shape, which not only facilitates the installation and positioning of the waterproof strip 3, but also plays a lateral fixing role for the waterproof strip 3, thereby playing a lateral fixing role for the side wall 2-1 of the lampshade 2, improving the connection firmness of the lampshade 2.
[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the side of the connecting fastener 4 away from the snap fastener 4-1 also has a locking buckle 4-2 that can be fastened to the side flange 1-1 of the base 1 or the outer flange 3-4 of the waterproof strip 3. When the outer flange 3-4 is provided on the waterproof strip 3, the locking buckle 4-2 is fastened to the outer flange 3-4; when the outer flange 3-4 is not provided on the waterproof strip 3, the locking buckle 4-2 is directly fastened to the side flange 1-1. The design of the locking buckle 4-2 enables the connecting fastener 4 to effectively connect the lampshade 2, the waterproof strip 3, and the base 1 together, further improving the connection firmness. Furthermore, the lower part of the connecting fastener 4 also has an extension 4-3 that can press against the bottom plate 3-1 of the waterproof strip 3, and the lower part of the extension 4-3 has a water channel 4-4. (Refer to...) Figure 9 As shown, the pressing action between the extension 4-3 and the waterproof strip 3 ensures the secure locking of the fastener 5, and also clamps the side wall 2-1 of the lampshade 2 between the extension 4-3 and the inner baffle 3-2 of the waterproof strip 3, further securing the lampshade 2. The water channel 4-4 allows the water guide channel 3a on the waterproof strip 3 to be open, improving drainage speed and waterproofing effect. The aforementioned connecting fastener 4, as an intermediate connecting component, achieves a quick and stable connection between the lampshade 2 and the base 1 through its snap-fit structure design, solving the connection problem between thin-walled lampshades and bases, and meeting the reliable connection requirements of outdoor lighting fixtures with different shapes.
[0048] In this embodiment, the outdoor lampshade connection structure preferably uses a soft material for its waterproof strip 3 to adapt to different outdoor lamp shapes, providing strong adaptability to the shape of the sealing edge and more reliable sealing. The connecting fastener 4 is preferably made of metal profiles, which can be cut to the required length according to different needs. It has high structural strength and is easy to manufacture, improving the connection between the lampshade and the base. The fastener 5 is preferably a locking bolt, and the connecting fastener 4 is also pre-set with threaded holes 4-5 for connecting with the locking bolt, making assembly simple and convenient. The lampshade 2 is preferably an acrylic transparent thin-walled cover structure, which can be vacuum-formed from acrylic sheets, making it easy to manufacture, low in manufacturing cost, and with good decorative effect. The base 1 can be made of metal to ensure the overall structural strength of the outdoor lamp.
[0049] This embodiment also discloses an outdoor lighting fixture. (Refer to...) Figure 1 , Figures 6 to 10 As shown, the outdoor lighting fixture has the aforementioned lampshade connection structure. A light source module 6 is mounted on the base 1, and the gap between the base 1 and the lampshade 2 is filled with waterproof adhesive for further waterproofing. This outdoor lighting fixture design makes it possible to use a thin-walled acrylic decorative cover as the lampshade, enriching the lighting effect and enhancing the design and aesthetics of the outdoor lighting fixture.
[0050] by Figure 1 , Figures 6 to 10 Taking the streetlight shape shown as an example, the base 1 is roughly rectangular with upturned ends. Since the base 1 is narrow on its wide side and positioned high, a waterproof strip 3 is not required; after assembly, the gap between the base 1 and the lampshade 2 can be filled with waterproof adhesive. A matching waterproof strip 3 is installed on the long side of the base 1. The drainage hole 3b and the external drainage hole 1-2 are both located at a low position, allowing rainwater to flow downwards, collect, and drain quickly. A base 1-3 for connecting the lamp post is also fixed to the lower part of the base 1. The base 1-3 and the base 1 can be made of the same material, and they can be connected using conventional installation methods, such as welding or bolting.
[0051] Of course, the shape of the outdoor lighting fixture in this embodiment is not limited to the shape shown in the above figures, and can be designed into any other shape according to design needs. For outdoor lighting fixtures with different shapes, only the shapes of the waterproof strip 3 and the connecting fasteners 4 need to be adjusted accordingly. The number of connecting fasteners 4 and the spacing between adjacent connecting fasteners 4 can be determined according to design needs, as long as the reliability of the connection between the lampshade 2 and the base 1 can be guaranteed.
[0052] When assembling the outdoor lighting fixture, first fix the light source module 6 on the base 1, then fasten the connecting fasteners 4 one by one onto the hanging holes 2-2 of the lampshade 2, and fasten the waterproof strip 3 against the side edge 1-1 of the base 1. Then, use fasteners 5 to pass through the corresponding through holes on the base 1 and the waterproof strip 3, and screw them into the pre-set threaded holes 4-5 on the connecting fasteners 4. After tightening, the assembly of the outdoor lighting fixture is completed. Finally, fill the gaps with waterproof glue to complete the installation.
[0053] This invention discloses an outdoor lampshade connection structure and an outdoor lamp. By setting a waterproof strip between the lampshade and the base, and using connecting fasteners inserted around the lampshade as components for connecting to the base, the connection problem between the thin-walled lampshade and the base is solved, greatly improving the connection firmness of the thin-walled lampshade. At the same time, the waterproof strip improves the waterproofness of the connection part. It has the advantages of convenient and quick installation, high connection firmness, good waterproof effect, low production cost, and no impact on the aesthetics of the outdoor lamp.
[0054] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
