Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a waterproof lampshade fixing structure. Background Technology

[0002] With the development of lighting technology, lamps are increasingly used outdoors, in humid, or special environments. To ensure good waterproof performance during use, waterproof lamps have emerged. As a crucial component of any lamp, the lampshade's fixing structure plays a key role in the structural design for achieving sealing and protection. The fixing structure of a waterproof lampshade not only needs to be sturdy and reliable but also requires excellent sealing to prevent rainwater, dust, and other impurities from entering the lamp and affecting its normal operation.

[0003] Existing lampshade fixing structures typically employ threaded connections, screw tightening, or sealing ring pressing to achieve lampshade fixation and sealing. For example, some lamps use threaded interfaces to screw the lampshade onto the lamp body, thus achieving a sealed fixation; other structures use multiple screws to press the lampshade onto the lamp body and add rubber sealing rings to the contact surfaces to improve waterproofing. However, in actual installation, screw or threaded connections are cumbersome to install or disassemble, affecting work efficiency. On the other hand, sealing structures often rely on manual alignment and tightening, and improper installation of the sealing rings can lead to leakage risks, resulting in unstable protective effects. Therefore, a waterproof lampshade fixing structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a waterproof lampshade fixing structure, which aims to improve the problems of the existing screw or threaded connection method, which is cumbersome to install or disassemble, affecting work efficiency, and the sealing structure relying on manual alignment and tightening. The sealing ring may leak due to improper installation, resulting in unstable protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0030] 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.

[0031] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a waterproof lampshade fixing structure, including a mounting frame 1. The mounting frame 1 has an adjustment mechanism inside for flexible adjustment of the lampshade's angle, position, or fastening state. An outer cover 18 is provided at the bottom of the mounting frame 1 to enclose and protect the lamp body, preventing rainwater, dust, or other impurities from entering the lamp body and ensuring the safe operation of electrical components. A quick-release mechanism is provided between the mounting frame 1 and the outer cover 18, facilitating quick installation and removal of the lampshade during daily maintenance, bulb replacement, or repair, improving work efficiency. The quick-release mechanism includes a fixing seat 10 and a fixing ring 11. The fixing seat 10 is located at the bottom of the mounting frame 1 and connected to the adjustment mechanism. The fixing ring 11 is fixedly connected to the edge of the outer cover 18. Claws 12 are fixedly connected to the side walls of both the fixing seat 10 and the fixing ring 11, and clamping plates 13 are fixedly connected to the side walls of both the fixing seat 10 and the fixing ring 11. The three parts are staggered, with the top claw 12 engaging with the bottom claw 13, and the top claw 13 engaging with the bottom claw 12. When the fixing seat 10 and the fixing ring 11 are in contact, the claws 12 and the claw 13 in the upper and lower parts can be engaged by twisting. A sealing ring 14 is fixedly connected to the bottom wall of the fixing seat 10, and a sealing ring 15 is fixedly connected to the top wall of the fixing ring 11. An annular groove 17 is opened inside the fixing seat 10, and the sealing ring 15 is slidably connected inside the annular groove 17. An annular groove 16 is opened inside the fixing ring 11, and the sealing ring 14 is slidably connected inside the annular groove 16. When the claw 12 engages with the claw 13, the fixing seat 10 and the fixing ring 11 will fit tightly together, and the sealing ring 14 will be inserted into the annular groove 16, and the sealing ring 15 will be inserted into the annular groove 17, ensuring the sealing between the fixing seat 10 and the fixing ring 11 and improving the waterproof effect.

[0032] Reference Figures 1-3The adjusting mechanism includes a sleeve 2, a toothed plate 3, and a toothed plate 4. The sleeve 2 is fixedly connected inside the mounting bracket 1, the toothed plate 3 is fixedly connected inside the sleeve 2, and the side wall of the toothed plate 4 is slidably connected inside the sleeve 2. A sliding rod 5 is fixedly connected to the side of the toothed plate 4 near the toothed plate 3. The sliding rod 5 passes through the side wall of the toothed plate 3 and extends to the outside. When an external pushing or pulling force is applied, it can quickly drive the synchronous movement of the toothed plate 4. A fixing rod 6 is fixedly connected to the side wall of the sleeve 2, and a sliding frame 7 is fixedly connected to the side wall of the sliding rod 5. The sliding frame 7 slides on one side. The fixed rod 6 is connected to the side wall of the fixed rod 6, which provides guidance for the slide 7 and ensures that the slide 7 moves smoothly along the predetermined path. The fixed seat 10 is fixedly connected to the slide 7. The sleeve 2 is equipped with a spring 8. One end of the slide rod 5 is fixedly connected to a handle 9. One end of the spring 8 is fixedly connected to the inside of the sleeve 2. The other end of the spring 8 abuts against the side wall of the toothed plate 4. When the external force is removed, the spring 8 will quickly reset, driving the toothed plate 4 to return to the initial position, providing an automatic reset function. The toothed plate 3 and the toothed plate 4 are engaged with each other.

[0033] Working principle: During installation, the lighting lamp is first installed at the bottom of the mounting base 10. Then, the outer cover 18 is placed over the lamp, and the fixing ring 11 is fitted with the mounting base 10. At the same time, the sealing ring 14 is inserted into the annular groove 16 and the sealing ring 15 is inserted into the annular groove 17 to ensure the sealing between the mounting base 10 and the fixing ring 11. While the mounting base 10 and the fixing ring 11 are fitted together, the claws 12 and the plates 13 on the upper and lower sides are interlocked. After they are fitted together, the outer cover 18 is twisted to move the claws 12 and the plates 13 below, and gradually the claws 12 and the plates 13 are engaged, thus completing the installation of the outer cover 18.

[0034] After the outer cover 18 is installed, the slide rod 5 can be moved by pushing the handle 9. At this time, the slide 7 will slide on the fixed rod 6. At the same time, the toothed plate 3 and the toothed plate 4 will be disengaged and the spring 8 will be compressed, causing it to deform. Then, the slide 7 can be deflected by turning the handle 9, thereby changing the lighting angle of the lamp and improving the flexibility of the equipment. After the angle is determined, the handle 9 is released. At this time, the spring 8 loses pressure and pushes the toothed plate 4 to move, so that the toothed plate 3 and the toothed plate 4 re-engage, thereby completing the fixation of the slide 7 and ensuring the stability of the angle.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
