Description

Technical Field

[0001] This application relates to the field of optical component fixing devices, and in particular to a lens sleeve. Background Technology

[0002] Lens sleeves are widely used in optical equipment such as cameras and camcorders to protect lenses from external environmental influences and ensure a stable connection between the lens and the equipment. With the rapid development of the optoelectronic industry, the requirements for lens sleeves are becoming increasingly stringent. They not only need to provide excellent protective performance but also meet the installation needs of various devices. Traditional lens sleeves are mostly made of metal or plastic, which, while offering some protection, have limitations in practical applications, particularly in terms of ease of installation and adaptability.

[0003] Currently, common lens sleeve designs mainly fall into two categories. One type uses a threaded connection to fix the lens to the device. This design is simple and reliable, but disassembly and assembly are relatively cumbersome, and it is prone to wear after repeated use. The other type uses a snap-on installation method. This method is convenient and quick to install, but its stability is poor, and it is prone to loosening during prolonged use. In addition, there is a type of lens sleeve that uses adhesive for fixation. Although this method is easy to install, it is difficult to replace once damaged, and the aging of the adhesive will affect the lifespan of the sleeve.

[0004] However, existing lens sleeves present numerous inconveniences during installation, especially for applications requiring frequent lens changes. Traditional threaded connections and snap-on installation methods are insufficient to meet the demands for quick and stable installation. Therefore, designing a lens sleeve that ensures both convenient installation and stability has become an urgent technical challenge. Utility Model Content

[0005] The purpose of this application is to provide a lens cover.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a lens sleeve, including a sleeve body, the sleeve body forming a light transmission channel, a first mounting member at one end of the sleeve body, a first mounting groove at the end of the first mounting member away from the sleeve body; a second mounting member at the end of the sleeve body away from the first mounting member, the second mounting member having a mounting hole.

[0007] By adopting the above technical solution, the lens sleeve features a simple structure and convenient installation. The light-transmitting channel formed by the sleeve body ensures effective light transmission while providing good protection against external impurities entering the lens and damaging internal components. The design of the first mounting groove on the first mounting component and the mounting holes on the second mounting component allows the lens sleeve to be easily connected to other parts, improving assembly efficiency and stability.

[0008] Optionally, the first mounting component and the second mounting component are integrally formed.

[0009] By adopting the above technical solution, the overall structure of the lens sleeve is made more stable and reliable, reducing the complexity of the assembly process and improving production efficiency. Specifically, the integrated design of the sleeve body, the first mounting component, and the second mounting component results in stronger connections between the components, avoiding loosening or detachment problems caused by the assembly of multiple parts, thereby improving the product's service life and reliability.

[0010] Optionally, the wall thickness of the rubber sleeve body is 0.5mm to 1.5mm.

[0011] By adopting the above technical solution, the wall thickness of the lens sleeve body is 0.5mm~1.5mm, which ensures that the lens sleeve has good flexibility and mechanical strength. The reasonable wall thickness range ensures that the lens sleeve has a certain structural strength to maintain its shape stability and protective function, while not affecting the flexibility of lens operation such as tilt-shifting due to excessive thickness, thus ensuring that the normal function of the projector's optical engine lens is not hindered. At the same time, it ensures a smooth light transmission channel, reduces light loss, and improves optical performance.

[0012] Optionally, the side of the rubber sleeve body away from the light transmission channel is provided with an annular reinforcing rib.

[0013] By adopting the above technical solution, an annular reinforcing rib is provided on the side of the rubber sleeve body away from the light transmission channel, which can significantly enhance the overall structural strength of the rubber sleeve, prevent deformation or damage caused by external forces during use, thereby extending the service life and improving the reliability of the product.

[0014] Optionally, multiple annular reinforcing ribs are provided, and the multiple annular reinforcing ribs are evenly spaced.

[0015] By adopting the above technical solution, the uniform spacing of multiple annular reinforcing ribs can significantly enhance the structural strength of the lens sleeve body, effectively prevent deformation caused by external impact or long-term use, and thus improve the overall stability and service life of the lens sleeve.

[0016] Optionally, the second mounting member extends in a direction away from the rubber sleeve body and is provided with an extension member. The extension member is arranged around the channel opening of the light transmission channel, and the extension member and the second mounting member together form a second mounting groove.

[0017] By adopting the above technical solution, the second mounting component extends away from the lens sleeve body and has an extension member. The extension member and the second mounting component together form a second mounting groove, thereby increasing the structural strength and stability of the second mounting component, making the lens sleeve more secure and reliable during installation, and effectively preventing loosening and detachment. At the same time, the design of the second mounting groove facilitates connection with other components, improving assembly efficiency and reliability.

[0018] Optionally, the bottom of the first mounting groove is recessed with a positioning groove.

[0019] By adopting the above technical solution, the positioning groove recessed in the bottom of the first mounting groove can enhance the connection stability between the lens sleeve and the camera lens or other optical components, effectively prevent loosening or falling off due to vibration or collision, and improve the reliability and service life of the product.

[0020] Optionally, the positioning slots are provided in multiple ways.

[0021] By adopting the above technical solution, multiple positioning slots can improve the positioning accuracy between the lens sleeve and the mating parts, ensure the stability during installation, avoid the overall installation failure caused by the failure of a single positioning point, and thus improve the reliability and service life of the product.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The first and second mounting parts of the lens sleeve are respectively provided with a first mounting groove and a mounting hole, which makes the lens sleeve easier to install and can quickly complete the connection with the lens and equipment, solving the problems of cumbersome disassembly and assembly and easy loosening of traditional threaded connection and snap-on installation methods;

[0024] 2. The lens sleeve body, the first mounting part, and the second mounting part are integrally molded, which improves the strength and stability of the overall structure, avoids wear caused by repeated disassembly and assembly, and extends the service life of the lens sleeve.

[0025] 3. The wall thickness of the lens case body is set at 0.5mm~1.5mm, which ensures sufficient rigidity while maintaining a lightweight design, effectively improving the protective performance and portability of the lens case. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] In this embodiment, refer to Figure 1-3 A lens sleeve includes a sleeve body 1, which forms a light-transmitting channel 2. One end of the sleeve body 1 is provided with a first mounting member 3, and the end of the first mounting member 3 away from the sleeve body 1 is provided with a first mounting groove 4. The end of the sleeve body 1 away from the first mounting member 3 is provided with a second mounting member 5, and the second mounting member 5 is provided with a mounting hole 6. This improves the ease and stability of installation and solves the inconvenience problems existing in the installation process of traditional lens sleeves.

[0034] Specifically, refer to Figure 1 The sleeve body 1 can be made of a flexible material, such as silicone or rubber, which can increase the flexibility of the sleeve while maintaining a certain strength, making it easy to install and remove. The wall thickness of the sleeve body 1 is 0.5 mm to 1.5 mm. This thickness range can ensure sufficient strength without being too thick and heavy to affect the portability of the device.

[0035] Reference Figure 2 The first mounting component 3 is located at one end of the rubber sleeve body 1, specifically at the opening of one side of the light transmission channel 2. The end of the first mounting component 3 furthest from the rubber sleeve body 1 has a first mounting groove 4. The first mounting groove 4 can be designed as square, circular, or other shapes to accommodate different types of lens interfaces. The design of the first mounting groove 4 allows the first mounting component 3 to be fitted and installed onto the lens. To improve installation accuracy, a positioning groove 10 is recessed at the bottom of the first mounting groove 4. One or more positioning grooves 10 can be provided to better secure the lens. Simultaneously, the positioning groove 10 can be used to avoid fasteners on the lens, such as bolts, thus preventing wear on the first mounting component 3.

[0036] Reference Figure 1 and Figure 3The second mounting component 5 is located at the end of the rubber sleeve body 1 away from the first mounting component 3, that is, at the other side of the light transmission channel 2. The second mounting component 5 is clamped and installed by the lens body housing, thus fixing the second mounting component 5 to the housing. After the first mounting component 3 and the second mounting component 5 are respectively fixed, the rubber sleeve body 1 is stretched to make the inner wall of the light transmission channel 2 flat, so as not to affect the light transmission effect. At the same time, the cooperation of the first mounting component 3, the second mounting component 5 and the rubber sleeve prevents external impurities from entering the lens and damaging the internal components of the lens.

[0037] The second mounting member 5 has mounting holes 6, which are used to securely mount the second mounting member 5 onto the housing using bolts or locating pins, thus limiting the rotation of the second mounting member 5 relative to the housing and improving the installation stability of the lens sleeve. To further enhance installation stability, the second mounting member 5 extends away from the sleeve body 1 and has an extension member 8. The extension member 8 is positioned around the opening of the light channel 2, and the extension member 8 and the second mounting member 5 together form a second mounting groove 9. The second mounting groove 9 increases the contact area between the second mounting member 5 and the housing, further improving installation stability. It also increases the path length for external impurities to enter the housing through the housing and the second mounting member 5, improving dustproof and waterproof performance.

[0038] The sleeve body 1 has an annular reinforcing rib 7 on the side away from the light transmission channel 2. One or more annular reinforcing ribs 7 can be provided, and these ribs are evenly spaced to effectively enhance the rigidity of the sleeve body 1 and prevent deformation during installation and use. The annular reinforcing rib 7 can be made of metal wire or rigid plastic to improve its strength and durability.

[0039] The implementation principle of this embodiment is as follows:

[0040] By using a flexible material for the lens sleeve body 1, the sleeve's flexibility and comfort are improved, making installation and removal more convenient. The first mounting member 3 and the second mounting member 5 enhance the ease and stability of installation. The annular reinforcing rib 7 on the sleeve body 1 effectively strengthens the sleeve's rigidity, preventing deformation during installation and use, thereby extending its service life. Overall, the design of this embodiment not only improves the ease and stability of lens sleeve installation but also enhances its durability and applicability, possessing high practical value.

[0041] Example 2

[0042] The difference between this embodiment and the above embodiments is that the rubber sleeve body 1, the first mounting part 3 and the second mounting part 5 are integrally formed, and preferably the rubber sleeve body 1, the first mounting part 3 and the second mounting part 5 are all made of silicone material.

[0043] The implementation principle of this embodiment is as follows:

[0044] By integrally molding the lens sleeve body 1, the first mounting part 3, and the second mounting part 5, the structural strength and stability of the entire lens sleeve can be significantly improved. The integral molding design avoids the weakness of the connection points caused by separate manufacturing, reducing the failure rate during installation. Simultaneously, the integral molding process simplifies the production flow, reduces manufacturing costs, and improves production efficiency. Furthermore, the integral molding design enhances the aesthetics of the lens sleeve, making its appearance more concise and elegant. Overall, the design of this embodiment not only improves the structural strength and stability of the lens sleeve but also simplifies the production process and reduces manufacturing costs, demonstrating high economic efficiency and practicality.

[0045] Example 3

[0046] The difference between this embodiment and the above embodiment is that the wall thickness of the rubber sleeve body 1 is 0.5 mm to 1.5 mm.

[0047] The implementation principle of this embodiment is as follows:

[0048] By controlling the wall thickness of the sleeve body 1 within the range of 0.5 mm to 1.5 mm, both strength and portability of the sleeve can be balanced. An excessively thin wall thickness may cause the sleeve to break easily during installation and use, while an excessively thick wall thickness increases the weight of the sleeve, affecting the portability of the device. A wall thickness of 0.5 mm to 1.5 mm ensures sufficient strength without being overly heavy, making the sleeve safer and more reliable during installation and use. Furthermore, an appropriate wall thickness also improves the sleeve's flexibility, making it easier to adapt to lenses of different shapes and sizes. Overall, the design of this embodiment not only improves the strength and portability of the sleeve but also enhances its flexibility and adaptability, resulting in high practicality and safety.

[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
