Description

Technical Field

[0001] This utility model relates to the field of lens clamping technology, and more specifically, to a lens clamp. Background Technology

[0002] When a lens is coated, because the lens itself has an arc-shaped groove, it is not easy to place it stably when coating the concave surface, which makes it easy to shake during the coating process and affect the coating effect.

[0003] Meanwhile, existing fixtures require the lenses to be removed and stacked together for packaging and transportation after coating, which can easily cause wear and tear. If each lens is packaged separately using separate tools, the process becomes quite cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a lens clamp that solves the problems of the troublesome coating of concave lenses, the easy wear and tear when the coated lenses are stacked together for transportation, and the cumbersome process of packaging and protecting each lens individually.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0024] A lens clamp includes a body 1. The top of the body 1 is provided with a placement groove 101. The four corners of the body 1 are provided with through holes 102. A through rod 2 is connected to the middle of the through hole 102. The two ends of the through rod 2 are connected with abutment covers 3. The bottom of the abutment cover 3 is provided with a fitting groove 301. The two ends of the through rod 2 are connected with limiting components. The abutment cover 3 is connected to the limiting components through the bottom fitting groove 301. The through rod 2 passes through several through holes 102 of the body 1 for connection.

[0025] First, the lens to be coated is placed into the placement groove 101. The curved groove of the placement groove 101 accommodates the curved lens. After coating, a through rod 2 is inserted into the through hole 102. Multiple bodies 1 containing lenses are then stacked together using the through rod 2 for storage. Then, abutment covers 3 are connected to both ends of the through rod 2 to abut against the top and bottom of the stacked bodies 1 for protection. This ensures the lenses are stored safely and packaged. The abutment covers 3 are connected to the through rod 2 by fitting groove 301 at the bottom.

[0026] Furthermore, the fitting groove 301 also includes a contraction groove 3011 and a limiting block 3012. The contraction groove 3011 is disposed on both sides of the inner wall of the fitting groove 301, and the limiting block 3012 is connected to the middle of the contraction groove 3011. One side of the limiting block 3012 is connected to the contraction groove 3011 by a spring. The portion of the limiting block 3012 protruding from the inner wall of the fitting groove 301 is trapezoidal. The limiting component includes a connecting end 201, a fitting rod 202, a connecting groove 2021, and a limiting ring groove 2022. The connecting end 201 is disposed at one end of the through rod 2. The fitting rod 202 is disposed at both ends of the through rod 2, the connecting groove 2021 is disposed at the bottom of the fitting rod 202, and the limiting ring groove 2022 is disposed on the side wall of the fitting rod 202. The end of the through rod 2 away from the connecting end 201 is provided with the connecting groove 2021. The connecting end 201 is threadedly engaged with the connecting groove 2021. The fitting rods 202 at both ends of the through rod 2 are connected through the connecting end 201 and the connecting groove 2021 respectively. The limiting ring groove 2022 is an annular groove in which the side wall of the fitting rod 202 engages with the limiting block 3012.

[0027] Meanwhile, connecting ends 201 and connecting grooves 2021 are respectively provided at both ends of the through rod 2. Through the thread matching of the two, other through rods 2 can be directly connected together, thereby increasing the length and allowing the main body 1 to be stored by overlapping more through rods 2. Finally, fitting rods 202 are connected to both ends of the through rod 2. The fitting rods 202 are used to connect with the fitting grooves 301. When the fitting rods 202 are fitted into the fitting grooves 301, they will abut against the limiting block 3012, forcing the limiting block to move. Block 3012 retracts into the shrinkage groove 3011 to allow the fitting rod 202 to extend in. After extending a certain distance, the limiting block 3012 aligns with the limiting ring groove 2022. The spring of the limiting block 3012 returns to its original position, causing it to pop out and fit into the limiting ring groove 2022. This limits the connection between the fitting rod 202 and the fitting groove 301, preventing it from easily detaching on its own. This limits the contact cover 3. If the stacked bodies 1 loosen due to shaking during transportation, the lens may be affected.

[0028] The following is a detailed implementation process of this utility model: First, the lens to be coated is placed into the placement groove 101. The curved groove of the placement groove 101 accommodates the curved lens. After coating, a through rod 2 is inserted into the through hole 102. Multiple bodies 1 containing lenses are then stacked together using the through rod 2 for storage. Abutment covers 3 are then attached to both ends of the through rod 2 to abut and protect the top and bottom of the stacked bodies 1, ensuring safe and uniform storage of the lenses. The abutment covers 3 are connected to the through rod 2 via a fitting groove 301 at the bottom. Connecting ends 201 and connecting grooves 2021 are provided at both ends of the through rod 2. The threads of these two parts allow for the connection of other through rods 2. The components are connected together to increase the length, allowing the main body 1 to be stacked more together for storage via the through rod 2. Finally, fitting rods 202 are connected to both ends of the through rod 2. The fitting rods 202 are used to connect with the fitting groove 301. When the fitting rod 202 is fitted into the fitting groove 301, it will press against the limiting block 3012, forcing the limiting block 3012 to retract into the shrinking groove 3011, allowing the fitting rod 202 to extend in. After extending a certain distance, the limiting block 3012 will align with the limiting ring groove 2022. The spring of the limiting block 3012 will return it to pop out and fit into the limiting ring groove 2022, thus limiting the connection between the fitting rod 202 and the fitting groove 301, preventing it from easily detaching on its own. This also limits the contact with the cover 3. If the stacked main bodies 1 loosen due to shaking during transportation, the lens may be affected.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
