Description

Technical Field

[0001] The utility model relates to the technical field of lens gaskets, in particular to a lens gasket that is not easily deformed. Background Art

[0002] Optical lenses are essential components in machine vision systems, directly impacting image quality and the implementation and effectiveness of algorithms. Lenses are composed of a combination of multiple optical lenses, often separated by a spacer (also known as a shim). The primary purpose of adding a spacer is to increase the magnification of the optical lens's visual system or shorten its working distance.

[0003] The most common lens gasket nowadays is a sheet-shaped ring, usually made of rubber material, which plays the role of spacing or adjusting the distance between two lenses in the optical lens.

[0004] Regarding the above technical conditions, there is also the defect that the lens gasket will be squeezed by the two adjacent lenses during use, and the lens gasket is made of rubber material, which is relatively soft and easily deformed by force.

[0005] Based on this, the present invention designs a lens gasket that is not easily deformed to solve the above problem. Utility Model Content

[0006] The purpose of the utility model is to provide a lens gasket that is not easily deformed, so as to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lens gasket that is not easy to deform, comprising a gasket body, the body being divided into an upper ring and a lower ring, the upper ring being fixedly arranged on the lower ring, the lower ring being provided with a fixing groove, two fixing grooves being provided on the lower ring, a reinforcement ring being fixedly arranged in the fixing groove, the reinforcement ring being between the upper ring and the lower ring, a plug-in ring being fixedly arranged on the lower ring, the plug-in ring being between the two fixing grooves, the upper ring being provided with a plug-in groove, and the plug-in ring being plugged into the plug-in groove.

[0008] Preferably, the fixing groove is divided into a first fixing groove and a second fixing groove, and the diameter of the first fixing groove is larger than the diameter of the second fixing groove.

[0009] Preferably, the reinforcement ring is made of metal material.

[0010] Preferably, the plug-in ring is made of rubber material, the main body is made of rubber material, and the rubber hardness of the plug-in ring is greater than the rubber hardness of the main body.

[0011] To sum up, the present application has the following beneficial technical effects: when the lens gasket is installed between the two lenses in the optical lens, the two lenses squeeze the main body, and the upper ring and the lower ring generate extrusion force on the metal ring and the plug-in ring respectively. However, since the metal ring is made of metal, the rubber hardness of the plug-in ring is greater than the rubber hardness of the main body. The metal ring and the plug-in ring are not easily deformed by force, and the main body is also not easily deformed by force, thereby achieving the effect of making the lens gasket not easily deformed by force.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] A lens gasket that is not easily deformed includes a main body of the lens gasket, which is divided into an upper ring 1 and a lower ring 2. The upper ring 1 is fixedly arranged on the lower ring 2, and a fixing groove is opened on the side of the lower ring 2 close to the upper ring 1. There are two fixing grooves on the lower ring 2.

[0022] A reinforcement ring 5 is fixed in the fixing groove, located between the upper ring 1 and the lower ring 2. Made of metal, it strengthens the main body. A plug-in ring 3 is fixed to the side of the lower ring 2 near the upper ring 1, located between the two fixing grooves. The upper ring 1 has a plug-in groove 4 that matches this ring 3 and into which it is inserted.

[0023] The plug-in ring 3 is made of rubber material, and the main body is also made of rubber material. The rubber hardness of the plug-in ring 3 is greater than that of the main body. The plug-in ring 3 increases the stress strength of the main body, making it less likely for the main body to be squeezed and deformed.

[0024] The fixing groove is divided into a first fixing groove 7 and a second fixing groove 6. The diameter of the first fixing groove 7 is larger than that of the second fixing groove 6. The first fixing groove 7 is arranged at one end of the lower ring 2 close to the outer wall, and the second fixing groove 6 is arranged at one end of the lower ring 2 close to the inner wall. Under the action of the metal ring in the first fixing groove 7, the plug-in ring 3 and the metal ring in the second fixing groove 6, the main body is not easily deformed by force.

[0025] The implementation principle of this embodiment is as follows: when the lens gasket is installed between the two lenses in the optical lens, the two lenses squeeze the main body, and the upper ring 1 and the lower ring 2 generate squeezing force on the metal ring and the plug-in ring 3 respectively. However, since the metal ring is made of metal and the rubber hardness of the plug-in ring 3 is greater than the rubber hardness of the main body, the metal ring and the plug-in ring 3 are not easily deformed by force, which makes the main body also less likely to be deformed by force, thereby achieving the effect of making the lens gasket less likely to be deformed by force.
