Description

Technical Field

[0001] This utility model relates to the field of lens barrel technology, and in particular to a lens barrel that prevents glue overflow. Background Technology

[0002] As the core structural component of various optical instruments such as telescopes and microscopes, the lens tube needs to be mass-produced. The lens, as the core component of the lens tube, needs to be installed on one side of the lens tube by applying adhesive to ensure that the lens tube meets the actual needs of the optical instrument during use.

[0003] Traditional lens barrels may have glue overflow onto the lens surface during the manufacturing process, causing contamination and affecting the performance of the lens barrel, thus failing to meet actual usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a lens barrel that prevents glue overflow, thereby solving the defect of glue overflow that occurs during the production process of existing lens barrels.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lens barrel that prevents glue overflow, including a mounting base and a mounting hole;

[0006] The mounting base has a mounting hole at its top, and a lens barrel body is disposed inside the mounting hole. The top of the lens barrel body has an anti-overflow structure.

[0007] The anti-overflow structure includes a limiting groove at the top of the lens barrel body, a lens is provided inside the limiting groove, anti-overflow holes are evenly provided inside the lens barrel body outside the limiting groove, and a storage groove is provided inside the lens barrel body outside the anti-overflow holes.

[0008] The mounting base has evenly spaced disassembly and assembly structures inside.

[0009] Preferably, the outer wall of the lens barrel body is provided with external threads, and the lens barrel body is threadedly connected to the mounting hole.

[0010] Preferably, the top of the limiting groove is designed to be inclined.

[0011] Preferably, the overflow prevention holes are evenly distributed inside the main body of the lens barrel.

[0012] Preferably, the disassembly and assembly structure includes threaded holes evenly opened inside the mounting base and built-in grooves evenly opened inside the mounting base. A limit block is provided inside the built-in groove, and a return spring is evenly fixed on one side of the limit block. Fastening bolts are provided inside the threaded holes.

[0013] Preferably, the threaded holes are evenly spaced inside the mounting base, and the built-in grooves are symmetrically distributed inside the mounting base.

[0014] Preferably, the bottom end of the limiting block is designed to be inclined, and the reset spring is fixedly connected to one side of the built-in groove.

[0015] The lens barrel provided by this utility model has the following advantages:

[0016] By setting an anti-overflow structure, anti-overflow holes are evenly opened inside the mounting base above the limiting groove. When the glue volume rises to one side of the anti-overflow hole during lens installation, the glue is discharged through the anti-overflow hole and discharged into the inside of the collection groove, so as to prevent glue from overflowing and contaminating the lens during the glue dripping process, thereby achieving the purpose of preventing glue overflow.

[0017] With a disassembly and assembly structure, the limiting block is subjected to the thrust of the return spring inside the built-in groove, and a bevel is provided at the bottom of the limiting block to facilitate pre-positioning of the limiting block during disassembly and assembly. The device is fixed by fastening bolts provided inside the threaded holes, thereby achieving the purpose of convenient and quick installation and positioning of the device.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1 - Figure 5 The present invention provides a lens barrel that prevents glue overflow, including a mounting base 1 and a mounting hole 2.

[0026] Reference Figure 1 and Figure 3 As shown, the top of the mounting base 1 has a mounting hole 2, and the lens barrel body 3 is arranged inside the mounting hole 2. The outer wall of the lens barrel body 3 has an external thread, and the lens barrel body 3 is threadedly connected to the mounting hole 2. The top of the lens barrel body 3 has an anti-overflow structure 4, which includes a limiting groove 401 at the top of the lens barrel body 3. The limiting groove 401 has a lens 402 arranged inside. The lens barrel body 3 outside the limiting groove 401 has anti-overflow holes 403 evenly arranged inside. The lens barrel body 3 outside the anti-overflow holes 403 has a storage groove 404. The top of the limiting groove 401 is inclined, and the anti-overflow holes 403 are evenly distributed inside the lens barrel body 3.

[0027] During the use of the lens barrel, the lens 402 needs to be installed. In order to improve the installation effect during the glue application process, an anti-overflow structure 4 is set up so that the lens 402 is placed inside the limiting groove 401 and glue application is performed inside the limiting groove 401 on the outside of the lens 402 to install the lens 402. Anti-overflow holes 403 are evenly opened inside the lens barrel body 3 above the limiting groove 401. When the glue moves to the top of the limiting groove 401, the glue moves through the anti-overflow holes 403 to the inside of the receiving groove 404, so as to prevent excessive glue application and glue overflow, which may cause contamination of the surface of the lens 402, thus greatly increasing the practicality of the device.

[0028] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the mounting base 1 has a disassembly and assembly structure 5 evenly distributed inside. The disassembly and assembly structure 5 includes threaded holes 501 evenly distributed inside the mounting base 1 and built-in grooves 502 evenly distributed inside the mounting base 1. A limit block 503 is provided inside the built-in groove 502. A return spring 504 is evenly fixed on one side of the limit block 503. A fastening bolt 505 is provided inside each of the threaded holes 501. The threaded holes 501 are evenly distributed inside the mounting base 1. The built-in grooves 502 are symmetrically distributed inside the mounting base 1. The bottom end of the limit block 503 is inclined. The return spring 504 is fixedly connected to one side of the built-in groove 502.

[0029] To facilitate quick assembly and disassembly during the use of this device, a disassembly structure 5 is provided. During installation, the limiting block 503 is pressed into the interior groove 502, and the return spring 504 pushes the limiting block 503 out of the interior groove 502 for pre-positioning. Threaded holes 501 are evenly provided at the corner of the mounting base 1, and the device is installed and positioned by fastening bolts 505. This prevents the device from shifting during use and allows the limiting block 503 to be pulled after removing the fastening bolts 505, moving it into the interior groove 502 to release the pre-position and disassemble the component, thus greatly increasing the practicality of the device.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
