Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to an integrated waterproof lens structure that is easy to assemble. Background Technology

[0002] In the fields of LED lighting, outdoor lighting fixtures and underwater lighting equipment, lenses are key optical components. Their sealing performance and assembly efficiency directly affect the reliability and production cost of products. Traditional lens structures often adopt a split design, consisting of multiple components such as the lens body, sealing ring, and pressure ring.

[0003] In existing technologies, the lens body is mainly fixed by pressure rings, and the upper and lower pressure rings are usually connected by threads. The assembly process of traditional threaded connections is relatively complicated, requiring each thread to be tightened individually. This is not only cumbersome but also inefficient. In addition, over time, the threaded connection may loosen due to mechanical vibration, temperature changes, or long-term use. Once the threads loosen, the stability of the lens will be affected, leading to a decrease in its positional accuracy in the optical system, which in turn affects the image quality. It will also cause gaps between the sealing ring and the lens, reducing its sealing and waterproof performance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated waterproof lens structure that is easy to assemble.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an integrated waterproof lens structure that is easy to assemble, including a lens, with a first assembly frame and a second assembly frame nested on the periphery of the lens respectively. Waterproof rubber rings are adhered to the side walls of the first assembly frame and the second assembly frame. A side groove is provided at the connection between the first assembly frame and the second assembly frame. A second latch is fixed to one side wall of the side groove. A sliding groove is provided on the other side wall of the side groove. A sliding rod is slidably connected inside the sliding groove. A first latch is rotatably connected to one side of the sliding rod. An annular piece and a U-shaped clip are stamped on the periphery of both the first latch and the second latch. A compression spring is fixed between the side wall of the sliding groove and the other side of the sliding rod.

[0006] Preferably, both the first and second assembly frames have an upper groove at the top connection. A snap-fit ​​fastener is fixed to one side wall of the upper groove, and one side of the snap-fit ​​fastener is an inclined protrusion. A bite-fit fastener is fixed to the other side wall of the upper groove, and one side of the bite-fit fastener has a slot. The side of the bite-fit fastener with the slot is an inclined plane. To further improve the stability between the assembly frame and the lens, this utility model provides a snap-fit ​​structure at the top connection of the assembly frame. During assembly, the first and second assembly frames are aligned and nested on the periphery of the lens. The bite-fit fastener on the side of the second assembly frame is squeezed along the inclined protrusion. Finally, the slot on its surface engages with the inclined protrusion through the inclined protrusion, further improving the tightness between the assembly frame and the lens.

[0007] Preferably, a slot is provided at the center of the second latch shaft, and an array of engaging grooves are provided on the inner wall of the slot. An engaging protrusion is slidably connected inside the engaging groove, and an engaging spring is fixed between the engaging protrusion and the inner wall of the engaging groove. A plug is stamped and extended at the center of the first latch shaft. When the first latch is inserted into the second latch, the plug enters the slot and squeezes the engaging protrusion. Under the action of the engaging spring, the engaging protrusion abuts against the plug, thereby improving the tightness between the first latch and the second latch.

[0008] Preferably, the end of the engaging protrusion is hemispherical, which reduces the contact area between the engaging protrusion and the plug, making it easier for the plug to enter the slot.

[0009] Preferably, the sidewall of the U-shaped clip and the surface of the annular piece are provided with anti-slip textures. The anti-slip textures increase the friction between the sidewall of the U-shaped clip and the annular piece, prevent relative sliding between the first latch and the second latch, and improve the tightness between the first latch and the second latch.

[0010] Preferably, the inner diameter of the U-shaped clip is equal to the width of the annular piece, which further improves the tightness between the first and second latches.

[0011] Preferably, a torsion spring is provided at the connection between the slide rod and the first latch. When the torsion spring is in its natural state, the first latch and the second latch are engaged with each other, further preventing the first latch and the second latch from loosening. When disassembling or assembling, rotate the first latch so that the first latch and the second latch are in a cross-shaped state, and then pull out the first latch.

[0012] Beneficial effects

[0013] In existing technologies, the lens body is mainly fixed by pressure rings, and the upper and lower pressure rings are usually connected by threads. The assembly process of traditional threaded connections is relatively complex, requiring each thread to be tightened individually, which is not only cumbersome but also inefficient. In addition, over time, the threaded connection may loosen due to mechanical vibration, temperature changes, or long-term use. Once the threads loosen, the stability of the lens will be affected, leading to a decrease in its positional accuracy in the optical system, which in turn affects the image quality. It will also cause gaps between the sealing ring and the lens, reducing its sealing and waterproof performance. To address these issues, this utility model adopts a detachable waterproof structure. During assembly, the first and second assembly frames are aligned and nested on the lens circumference, and waterproof rubber rings are adhered to the side walls of the first and second assembly frames. Pulling the first latches on both sides of the assembly frame makes them fit with the second latches. Finally, rotating the first latches causes the U-shaped clips on the circumference of the first latches to engage with the annular pieces on the circumference of the second latches. This not only simplifies assembly and increases assembly efficiency but also prevents loosening and provides good sealing and waterproof performance. Attached Figure Description

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0028] Reference Figure 1-9 The easily assembled integrated waterproof lens structure includes a lens 1. A first assembly frame 2 and a second assembly frame 3 are nested on the periphery of the lens 1. Waterproof rubber rings are bonded to the side walls of the first assembly frame 2 and the second assembly frame 3. A side groove 12 is provided at the connection between the first assembly frame 2 and the second assembly frame 3. A second latch 8 is fixed to one side wall of the side groove 12. A sliding groove 13 is provided on the other side wall of the side groove 12. A sliding rod 5 is slidably connected inside the sliding groove 13. A first latch 4 is rotatably connected to one side of the sliding rod 5. A torsion spring is provided at the connection between the sliding rod 5 and the first latch 4. When the torsion spring is in its natural state, the first latch 4 and the second latch 8 are engaged with each other to further prevent the first latch 4 and the second latch 8 from loosening. During disassembly and assembly, the first latch 4 is rotated so that the first latch 4 and the second latch 8 are in a cross-shaped state, and then the first latch 4 can be pulled out. Both the first latch 4 and the second latch 8 have annular pieces 7 and U-shaped clips 6 stamped on their circumferences. Anti-slip textures are formed on the sidewall of the U-shaped clip 6 and the surface of the annular piece 7, increasing the friction between them and preventing relative sliding between the first latch 4 and the second latch 8, thus improving the tightness between them. The inner diameter of the U-shaped clip 6 is equal to the width of the annular piece 7, further enhancing the tightness between the first latch 4 and the second latch 8. A compression spring 14 is fixed between the sidewall of the slide groove 13 and the other side of the slide rod 5.

[0029] Both the first assembly frame 2 and the second assembly frame 3 have an upper groove 11 at the top connection. A snap fastener 10 is fixed to one side wall of the upper groove 11. One side of the snap fastener 10 is an inclined protrusion 1001. The other side wall of the upper groove 11 is fixed to a snap fastener 9. One side of the snap fastener 9 is a slot 901, and the side of the snap fastener 9 with the slot 901 is an inclined plane. In order to further improve the stability between the assembly frame and the lens 1, this utility model sets a snap fastener structure at the top connection of the assembly frame. During assembly, the first assembly frame 2 and the second assembly frame 3 are aligned and nested on the periphery of the lens 1. The snap fastener 9 on the side of the second assembly frame 3 is squeezed along the inclined protrusion 1001. Finally, through the inclined protrusion 1001, the slot 901 on its surface is engaged with the inclined protrusion 1001, which further improves the tightness between the assembly frame and the lens 1.

[0030] A slot 15 is provided at the axis of the second latch 8. An array of engaging grooves is formed on the inner wall of the slot 15. An engaging protrusion 17 is slidably connected inside the engaging groove. The end of the engaging protrusion 17 is hemispherical, reducing the contact area between the engaging protrusion 17 and the plug 18, facilitating the insertion of the plug 18 into the slot 15. An engaging spring 16 is fixed between the engaging protrusion 17 and the inner wall of the engaging groove. A plug 18 is stamped and extended from the axis of the first latch 4. When the first latch 4 is inserted into the second latch 8, the plug 18 enters the slot 15, pressing against the engaging protrusion 17. Under the action of the engaging spring 16, the engaging protrusion 17 abuts against the plug 18, improving the tightness between the first latch 4 and the second latch 8.

[0031] The working principle of this utility model is as follows: During assembly, the first assembly frame 2 and the second assembly frame 3 are aligned and nested on the periphery of the lens 1. Waterproof rubber rings are glued to the side walls of the first assembly frame 2 and the second assembly frame 3. The first latch 4 on both sides of the assembly frame is pulled to fit with the second latch 8. Finally, the first latch 4 is rotated so that the U-shaped clip 6 on the periphery of the first latch 4 engages with the annular piece 7 on the periphery of the second latch 8. When the first latch 4 is inserted into the second latch 8, the plug 18 enters the slot 15 and squeezes the locking protrusion 17. Under the action of the locking spring 16, the locking protrusion 17 abuts against the plug 18. At the same time, the biting fastener 9 on the side of the second assembly frame 3 is squeezed along the inclined protrusion 1001. Finally, through the inclined protrusion 1001, the surface groove 901 engages with the inclined protrusion 1001.
