Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to a waterproof and dustproof optical lens sealing structure. Background Technology

[0002] In the field of modern technology, optical lenses are widely used in many fields such as security monitoring, industrial inspection, aerospace, and photography. In these application scenarios, optical lenses often face the influence of complex environmental factors such as dust and moisture. Dust entering the lens will adhere to the surface of the optical element, causing blurry images and spots, which seriously affects the image quality. Moisture entering the lens may not only cause the lens to fog up, but may also cause mold spots and other phenomena that affect its performance. Therefore, a sealing structure is required to achieve its sealing.

[0003] Currently, when sealing optical lenses, internal sealing gaskets are commonly used. However, for lenses located on the outside, sealing only the inside allows moisture and dust to accumulate in the outer gaps. Furthermore, the lens cannot provide a completely sealed environment when a UV filter or lens cap is installed. Therefore, during prolonged storage, moisture may enter the outer side of the lens element through gaps in the lens cap or UV filter, potentially causing mold growth and affecting its performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a waterproof and dustproof optical lens sealing structure that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof and dustproof optical lens sealing structure includes: a lens body and a lens cap disposed at the end of the lens body, and further includes: a mounting ring disposed on the lens body; and a sealing rubber fixedly disposed on the mounting ring, with one end of the sealing rubber extending to the lens cap, the sealing rubber being used to seal the connection between the lens cap and the lens body.

[0007] Preferably, a UV filter is provided between the lens body and the lens cap, and the sealing rubber is used to cover the connection between the lens cap and the UV filter and the connection between the UV filter and the lens body.

[0008] To facilitate the replacement of the sealing rubber, a threaded ring is further fixedly connected to the lens body, the mounting ring is threadedly connected to the threaded ring, and a sealing ring is fixedly connected between the mounting ring and the lens body.

[0009] To improve its sealing effect, preferably, an elastic ring is fixedly connected to the end of the sealing rubber, and the elastic force of the elastic ring is greater than that of the sealing rubber.

[0010] To facilitate pulling the sealing rubber, preferably, the elastic ring is circumferentially fixed with multiple elastic fixing bands.

[0011] To facilitate the retraction of the sealing rubber, a first annular groove and a second annular groove are further provided on the sealing rubber. The first annular groove is located on the outside of the UV filter, and the second annular groove is located on the outside of the lens body.

[0012] Compared with the prior art, this utility model provides a waterproof and dustproof optical lens sealing structure, which has the following beneficial effects:

[0013] 1. This waterproof and dustproof optical lens sealing structure, when the lens cap is installed on the lens body with a UV filter, the sealing rubber is tightly attached to the lens cap under the action of the elastic ring. At this time, the connection between the lens cap and the UV filter and the connection between the UV filter and the lens body are covered by the sealing rubber, thereby achieving a seal when the lens is not in use, preventing water and dust from entering the outer gaps of the lens body after a long period of time, thus preventing mold spots from appearing on the outer side of the lens body and the outer gaps.

[0014] 2. The waterproof and dustproof optical lens sealing structure uses a mounting ring, sealing ring and threaded ring to achieve a detachable sealing connection, which facilitates the regular replacement of the sealing rubber and prevents the sealing rubber from aging and affecting its sealing effect.

[0015] 3. The waterproof and dustproof optical lens sealing structure, by setting the first annular notch and the second annular notch, facilitates the folding of the sealing rubber and can also prevent the end of the sealing rubber from curling up after folding.

[0016] The parts not described in this device are the same as or can be implemented using existing technology. This utility model prevents moisture and dust from entering the outer gaps of the lens body after prolonged placement, thereby preventing mold spots from appearing on the outer side of the lens body and the outer gaps, and effectively improving its waterproof and dustproof effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figures 1-5 A waterproof and dustproof optical lens sealing structure includes: a lens body 1 and a lens cap 102 disposed at the end of the lens body 1, and further includes: a mounting ring 201 disposed on the lens body 1; and a sealing rubber 203 fixedly disposed on the mounting ring 201, with one end of the sealing rubber 203 extending to the lens cap 102. The sealing rubber 203 is used to seal the connection between the lens cap 102 and the lens body 1.

[0025] A UV filter 101 is provided between the lens body 1 and the lens cap 102. The sealing rubber 203 is used to cover the connection between the lens cap 102 and the UV filter 101 and the connection between the UV filter 101 and the lens body 1.

[0026] A threaded ring 2 is fixedly connected to the lens body 1, and a mounting ring 201 is threadedly connected to the threaded ring 2. A sealing ring 202 is fixedly connected between the mounting ring 201 and the lens body 1.

[0027] An elastic ring 204 is fixedly connected to the end of the sealing rubber 203, and the elastic force of the elastic ring 204 is greater than the elastic force of the sealing rubber 203.

[0028] When the lens cap 102 is installed on the lens body 1 with the UV filter 101, the sealing rubber 203 is tightly attached to the lens cap 102 under the action of the elastic ring 204. At this time, the connection between the lens cap 102 and the UV filter 101 and the connection between the UV filter 101 and the lens body 1 are covered by the sealing rubber 203, so as to achieve a seal when the lens is not in use, preventing moisture and dust from entering the outer gap of the lens body 1 after a long period of time, thereby preventing mold spots from appearing on the outer side of the lens body 1 and the outer gap.

[0029] When the lens body 1 is needed, the end of the sealing rubber 203 is lifted and folded back so that it only seals the UV filter 101 and the lens body 1, thus providing a certain degree of waterproof and dustproof effect during use.

[0030] The elastic ring 204 can provide a large compressive force to the end of the sealing rubber 203, thereby improving its sealing effect. At this time, the elasticity of the sealing rubber 203 can be appropriately reduced to facilitate its folding process.

[0031] The detachable sealing connection is achieved by using an installation ring 201, a sealing ring 202, and a threaded ring 2, which facilitates the periodic replacement of the sealing rubber 203 and prevents the aging of the sealing rubber 203 from affecting its sealing effect.

[0032] Example 2: Refer to Figures 1-5 The waterproof and dustproof optical lens sealing structure is basically the same as that in Example 1. Furthermore, multiple elastic fixing bands 205 are circumferentially fixedly connected on the elastic ring 204.

[0033] The sealing rubber 203 has a first annular groove 206 and a second annular groove 207. The first annular groove 206 is located on the outside of the UV filter 101, and the second annular groove 207 is located on the outside of the lens body 1.

[0034] When pulling the sealing rubber 203 to fold back, simply hold the elastic fixing strap 205 to fold the sealing rubber 203 back, which makes it easier to operate the sealing rubber 203.

[0035] In actual use, by setting the first annular notch 206 and the second annular notch 207, it is convenient to fold the sealing rubber 203 back, and at the same time, it can prevent the end of the sealing rubber 203 from curling up after folding.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
