Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical lenses, in particular to a replaceable optical lens device. Background Art
[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.) that affects the wavefront curvature of light. It is a device that can aggregate or disperse light, and the resulting image can be real or virtual. It is widely used in security, car wear, digital cameras, lasers, optical instruments and other fields;
[0003] However, the lenses used in existing lenses are usually fixed and cannot be removed and replaced. When the lens is damaged or the lens surface becomes yellow and blurred, resulting in the lens being unable to be used normally, the lens can only be discarded as a whole and a new lens used, which increases the cost of use;
[0004] In order to solve the above problems, the present application proposes a replaceable optical lens device. Utility Model Content
[0005] The utility model aims to provide a replaceable optical lens device, which is mainly used to solve the problem that the lens on the existing lens cannot be disassembled and replaced, and when the lens is damaged, the lens can only be replaced as a whole, which increases the cost of using the lens.
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:
[0007] A replaceable optical lens device comprises a handle and a lens, wherein the upper end of the handle is fixedly connected to a first fixing ring matching the lens, the first fixing ring is slidably connected to the second fixing ring, the bottom of the second fixing ring is fixedly connected to a rubber pad, the top of the handle is provided with a sliding cavity, the bottom of the inner wall of the sliding cavity is fixedly connected to a telescopic rod, the upper end of the telescopic rod is fixedly connected to an insertion block, the insertion block is slidably connected to the inner wall of the sliding cavity, the outer wall of the telescopic rod is sleeved with a spring, the lower end of the spring is fixedly connected to the bottom of the inner wall of the sliding cavity, and the upper end is fixedly connected to the insertion block, the outer wall of the second fixing ring is provided with a slot matching the insertion block, one side of the insertion block is fixedly connected to a connecting block, the other side of the connecting block extends out of the handle and is slidably connected to the handle, the handle is provided with a vertical groove matching the connecting block, the side of the connecting block extending out of the handle is fixedly connected to a movable shell, and the movable shell is slidably connected to the handle.
[0008] The working principle and beneficial effects of the utility model:
[0009] 1. Working principle: When the lens is severely worn or damaged after long-term use, people can pull down the movable shell on the handle to drive the plug-in block inside the sliding cavity to move downward, and at the same time make the telescopic rod and the spring in a compressed state. When the plug-in block is out of the slot on the second fixing ring, the second fixing ring can be removed and the lens can be replaced. After the lens is replaced, install the second fixing ring and align the slot on its outer wall with the plug-in block. After loosening the movable shell, the plug-in block will move upward under the action of the telescopic rod and the spring. When the plug-in block is inserted into the slot, the lens can be used normally.
[0010] 2. Beneficial effect: When the lens is damaged or severely worn after long-term use, the lens can be replaced by removing the second fixing ring. The advantage of this arrangement is that when the lens on the lens cannot be used normally, only the lens needs to be replaced and the lens can be used normally without replacing the entire lens, thereby effectively saving the cost of using the lens.
[0011] Preferably, a plurality of guide blocks are fixedly connected to the bottom of the second fixing ring, and a guide groove matching the guide block is formed on the inner wall of the first fixing ring. After people replace the lens on the lens, they need to install the second fixing ring. When installing the second fixing ring, the plurality of guide blocks at the bottom are inserted into the guide groove on the first fixing ring. This not only can provide a better limiting effect on the second fixing ring, making the lens more stable when in use, but also can enable people to install the second fixing ring on the first fixing ring so that the insert block can face the slot on the second fixing ring, thereby making it more convenient for people to install the second fixing ring.
[0012] Preferably, a screw passes through one side of the movable shell, and the screw is threadedly connected to the handle. After people have replaced the lens on the lens, they can tighten the screw on the movable shell to further limit the movable shell, thereby making the lens more stable when in use.
[0013] Preferably, there are two telescopic rods, which are symmetrically arranged inside the sliding cavity. By setting the number of telescopic rods inside the sliding cavity to two and sleeved with springs on the outer walls of the telescopic rods, after the plug is inserted into the slot, the telescopic rods and the springs can exert a greater squeezing force on the plug, thereby making the plug better limit the second fixing ring.
[0014] Preferably, a magnet is fixedly connected to the side of the guide block away from the second fixing ring, and an iron sheet attracted to the magnet is fixedly connected to the inner wall of the guide groove. When people install the second fixing ring, they insert the guide block at the bottom into the guide groove on the first fixing ring. Through the magnet set on the guide block and the iron sheet set inside the guide groove, when the guide block is inserted into the guide groove, the magnet and the iron sheet are attracted to each other, so that the second fixing ring can be fixed on the first fixing ring, thereby making it more convenient for people to install the second fixing ring.
[0015] Preferably, the screw is an embedded hexagonal setting, and the outermost end of the screw does not exceed the outer wall of the handle. After the screw is installed, the outermost end of the screw does not exceed the outer wall of the handle, so that it will not bulge out and cause wear. The screw is an embedded hexagonal setting. The screw with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.
[0016] Preferably, both sides of the moving shell are fixedly connected with a plurality of protrusions, and the protrusions are equidistantly distributed on both sides of the moving shell in a linear array. When people replace the lens on the lens, they need to remove the second fixing ring first. When removing the second fixing ring, people need to pull the moving shell downward. The plurality of protrusions arranged on both sides of the moving shell can effectively increase the friction between people's hands and the moving shell, thereby preventing people's hands from slipping when pulling the moving shell.
