Description

Technical Field

[0001] This utility model relates to the field of lens barrel structure technology, specifically to a lens barrel structure that improves the application of adhesive to the lens. Background Technology

[0002] The lens is an important component of a camera device for capturing images. It is an optical device and consists of a lens barrel and lens elements. In order to ensure that the lens elements are fully fixed and connected to the lens barrel, glue is used during lens installation to bond the lens elements to the lens barrel, thereby forming a stable lens.

[0003] In existing lens barrel structures, when installing lenses, glue is often applied to the outer circular surface, i.e., the edge, of the lens. The lens is then inserted into the lens barrel to fit perfectly, and the glue at the edge of the lens adheres to the inner surface of the lens barrel. However, this glue application method can easily cause glue to overflow from the mating surface during lens installation, resulting in the lens being covered with glue, affecting the lens's sharpness and hindering its use.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed an improved lens barrel structure with full coating. Utility Model Content

[0005] The purpose of this invention is to provide an improved lens barrel structure with fully coated adhesive, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved lens barrel structure for applying adhesive to a lens, comprising a lens barrel body, a protrusion provided in the middle of the inner surface of the lens barrel body, grooves evenly distributed on the inner surface of the lens barrel body to the left of the protrusion, springs fixedly connected to the inner surface of each groove, and a stop block fixedly connected to the end of each spring near the opening of the groove.

[0007] Preferably, the end of the stop block that connects to the spring is located on the inner surface of the groove and slides in contact with it, and the end of the stop block away from the spring protrudes out of the groove, and the left side of the protruding part of the stop block is set as a slope.

[0008] Preferably, the left side of the protruding surface is configured as a bearing surface, and an annular groove is formed on the surface of the bearing surface.

[0009] Preferably, the diameter of the groove opening is greater than or equal to 1 mm, and the depth of the groove is 2 mm.

[0010] Preferably, the right side of the protrusion is configured as a pressing surface, and the inner surface of the lens barrel body is provided with threaded texture on the right side of the protrusion.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of groove, spring and stop, when the lens is installed, it is inserted into the lens barrel body. The inclined surface pushes the stop to retract into the groove and squeeze the spring. When the lens is attached to the leftmost surface of the protrusion, that is, the lens is installed in place, the stop will extend out of the groove again under the action of the spring and use the right right angle surface to attach to the edge of the left surface of the lens, so that the lens can be directly fixed and positioned. This means that when installing the lens, no glue or a small amount of glue is needed to ensure the lens is fixed, thus completely avoiding the situation of glue covering the lens area.

[0013] 2. This utility model, through the setting of the bearing surface and the annular groove, allows the protrusion to adhere to the lens using the left bearing surface. The bearing surface provides a certain range for adhesive application, thereby allowing the adhesive application to be determined and avoiding excessive application of adhesive. This improves the situation where the lens is covered with adhesive. Even if over-application occurs, the excess adhesive will be squeezed into the annular groove during lens bonding. The annular groove provides a space to contain the excess adhesive, preventing it from overflowing onto the lens surface under pressure, thus further preventing the lens from being covered with adhesive.

[0018] 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.

[0019] like Figures 1-3As shown, an improved lens barrel structure for applying adhesive to a lens includes a lens barrel body 1. A protrusion 2 is provided in the middle of the inner surface of the lens barrel body 1. Grooves 3 are evenly distributed on the inner surface of the lens barrel body 1 to the left of the protrusion 2. Springs 4 are fixedly connected to the inner surface of each groove 3. A stop block 5 is fixedly connected to the end of each spring 4 near the opening of the groove 3.

[0020] The end of the stop block 5 that connects to the spring 4 slides in contact with the inner surface of the groove 3, and the end of the stop block 5 that is away from the spring 4 protrudes out of the groove 3, and the left side of the protruding part of the stop block 5 is set as a slope.

[0021] By adopting the above technical solution, when the lens is installed, it is inserted into the lens barrel body 1. The inclined surface pushes the stop 5 to retract into the groove 3 and squeeze the spring 4. When the lens is attached to the leftmost surface of the protrusion 2, that is, the lens is installed in place, the stop 5 will extend out of the groove 3 again under the action of the spring 4 and use the right right angle surface to attach to the edge of the left surface of the lens, so that the lens can be directly fixed and positioned. This allows the lens barrel body 1 to ensure the lens is fixed without the use of glue or with a small amount of glue when installing the lens.

[0022] Furthermore, the left side of the protrusion 2 is set as a bearing surface 6, and an annular groove 7 is formed on the surface of the bearing surface 6;

[0023] The diameter of the groove opening of the annular groove 7 is greater than or equal to 1 mm, and the depth of the annular groove 7 is 2 mm.

[0024] By adopting the above technical solution, the protrusion 2 is attached to the lens by the left supporting surface 6. The supporting surface 6 provides a certain range for adhesive application, so that the adhesive application range can be determined and excessive adhesive application can be avoided, thereby improving the situation of the lens being covered with adhesive.

[0025] Even if the adhesive is over-applied, during the lens bonding process, the excess adhesive will be squeezed into the annular groove 7. The annular groove 7 provides a space for the excess adhesive to be contained, preventing the excess adhesive from overflowing onto the lens surface under pressure.

[0026] Furthermore, the right side of the protrusion 2 is set as a pressing surface 8, and the inner surface of the lens barrel body 1 is provided with a threaded pattern 9 on the right side of the protrusion 2.

[0027] By adopting the above technical solution, the thread pattern 9 enables the lens barrel body 1 to be quickly installed with the end of the camera equipment;

[0028] The clamping surface 8 limits the maximum screwing depth between the lens barrel body 1 and the end bracket of the camera equipment, avoiding over-assembly that could cause the lens barrel body 1 to be squeezed and broken.

[0029] Working principle: When using this improved lens barrel structure with full adhesive application, firstly, the bearing surface 6 provides a certain range for adhesive application, thus ensuring the coverage area is defined and avoiding over-application of adhesive. After adhesive application, the lens is inserted into the lens barrel body 1. The inclined surface pushes the stop 5 to retract into the groove 3 and compress the spring 4. When the lens adheres to the bearing surface 6, i.e., the lens is installed in place, the stop 5 will extend out of the groove 3 again under the action of the spring 4 and adhere to the left edge of the lens surface using its right right-angled surface, thus directly fixing and positioning the lens. At this time, the edge of the lens also adheres to the adhesive on the surface of the bearing surface 6, further fixing the lens. Even if over-application occurs during the initial adhesive application, the excess adhesive will be squeezed into the annular groove 7 when the lens is adhered. The annular groove 7 provides a space for the excess adhesive to be contained, preventing excess adhesive from overflowing onto the lens surface under pressure, thus further preventing the lens from being completely covered with adhesive. This is the working principle of this improved lens barrel structure with full adhesive application.
