Description

Technical Field

[0001] This utility model relates to the field of lens protective cover technology, specifically a protective cover for imaging lenses. Background Technology

[0002] A camera is an optical device used to capture images. Its basic function is to focus light onto a photosensitive element (such as film or an electronic sensor) through a lens, thereby forming an image. The lens is a component of a camera, consisting of multiple optical elements arranged and combined for image formation.

[0003] A camera consists of a body, a lens, and a protective cap. The lens is used for imaging, and the protective cap is used to protect the lens. When the camera is not in use, the protective cap is threaded onto the lens to protect the optical elements inside the lens and prevent them from being damaged.

[0004] Regarding the above technical conditions, there is also a drawback: the cover is installed on the optical lens by a threaded connection, which makes the use of the cover inconvenient.

[0005] Based on this, the present invention designs a protective cover for imaging lenses to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a protective cover for imaging lenses to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for an imaging lens, comprising a lens and a cover body, the cover body being disposed on the lens, four snap-fit ​​plates being fixedly disposed on the lens, the snap-fit ​​plates forming a snap-fit ​​groove with the lens, two fixing holes being provided on the cover body, fixing plates being inserted into the fixing holes, a first positioning plate being fixedly connected to the fixing plate, the first positioning plate being snapped into the snap-fit ​​groove, a plurality of springs being fixedly connected to the fixing holes, the springs being fixedly connected to the fixing plates, the springs being between the fixing holes and the fixing plates, the springs being in a compressed state, and two second positioning plates being fixedly disposed on the cover body, the second positioning plates being snapped into the snap-fit ​​groove.

[0008] Preferably, a limiting groove is provided on the fixing plate, and a limiting block is fixedly connected in the fixing hole, with the limiting block inserted into the limiting groove.

[0009] Preferably, the first positioning plate and the second positioning plate are staggered on the cover.

[0010] Preferably, the end of the first positioning plate away from the cover is closed, and the end of the second positioning plate away from the cover is also closed.

[0011] Preferably, a protective pad is fixedly connected to the snap-fit ​​plate.

[0012] Preferably, the cover has an auxiliary groove, and two auxiliary grooves are mirror-arranged on the cover.

[0013] In summary, this application has the following beneficial technical effects: During use, the cover is lifted via the auxiliary slot, and the first and second positioning plates of the cover are placed against the lens, causing the first and second positioning plates to be offset from the locking plate on the lens. When the second positioning plate is against the lens, the spring is compressed. Then, the cover is rotated via the auxiliary slot, allowing the first and second positioning plates to engage with the locking slots respectively. Because the spring is compressed, it generates action and reaction forces. Under the action and reaction forces, the first positioning plate is more tightly pressed against the locking slot, making it less likely for either the first or second positioning plate to separate. The cover is stably installed on the lens, thus making the use of the protective cover more convenient. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] A protective cover for an imaging lens includes a lens 1 and a cover body 3. The cover body 3 is disposed on the lens 1 and protects the lens inside the lens 1. Four snap-fit ​​plates 2 are fixedly disposed on the lens 1, and a snap-fit ​​groove is formed between the snap-fit ​​plates 2 and the lens 1.

[0024] The cover 3 has two fixing holes 10, and a fixing plate 7 is inserted into the fixing hole 10. The fixing plate 7 is fixedly connected to a first positioning plate 5, which is snapped into a snap-fit ​​groove. Multiple springs 11 are fixedly connected to the fixing hole 10. The springs 11 are fixedly connected to the snap-fit ​​groove and are located between the fixing hole 10 and the fixing plate 7. The springs 11 are in a compressed state.

[0025] Two second positioning plates 6 are fixedly mounted on the cover 3, and the second positioning plates 6 are snapped into the snap-fit ​​grooves. The two first positioning plates 5 and the second positioning plates 6 are staggered on the cover 3. In use, the first positioning plates 5 and the second positioning plates 6 are pressed against the lens 1. The cover 3 is rotated so that the first positioning plates 5 and the second positioning plates 6 are snapped into the snap-fit ​​grooves respectively. Under the action of the first positioning plates 5, the second positioning plates 6 and the snap-fit ​​plate 2, the cover is stably installed on the lens 1.

[0026] When the first positioning plate 5 and the second positioning plate 6 are respectively engaged in the engagement groove, the spring 11 is in a compressed state. The spring 11 generates action and reaction forces. Under the action and reaction forces, the first positioning plate 5 fits more closely against the engagement groove, and the first positioning plate 5 is not easy to separate from the engagement groove, thus increasing the installation stability of the cover 3 on the lens 1.

[0027] A limiting groove 9 is provided on the fixing rod, and a limiting block 8 is fixedly connected in the fixing hole 10. The limiting block 8 is inserted into the limiting groove 9. The limiting block 8 and the limiting groove 9 make it difficult for the fixing plate 7 to detach from the fixing hole 10, and at the same time increase the stability of the movement of the fixing plate 7 caused by the compression or extension of the spring 11.

[0028] The end of the first positioning plate 5 away from the cover 3 is designed to be closed, and the end of the second positioning plate 6 away from the cover 3 is designed to be closed. By designing the first positioning plate 5 and the second positioning plate 6 to be closed, it is convenient to snap the first positioning plate 5 and the second positioning plate 6 into the snap-fit ​​groove.

[0029] An auxiliary groove 4 is provided on the side of the cover 3 away from the lens 1. There are two mirror images of the auxiliary groove 4 on the cover 3. The auxiliary groove 4 facilitates the rotation of the cover 3 to engage the first positioning plate 5 and the second positioning plate 6 into the engagement groove. A protective pad (not shown in the figure) is fixedly connected to the engagement plate 2. When the first positioning plate 5 and the second positioning plate 6 are engaged in the engagement groove, the protective pad presses against the first positioning plate 5 and the second positioning plate 6 respectively, thereby reducing the friction between the first positioning plate 5 and the second positioning plate 6 and the engagement plate 2.

[0030] The implementation principle of this embodiment is as follows: In use, the cover 3 is lifted through the auxiliary groove 4, and the first positioning plate 5 and the second positioning plate 6 of the cover 3 are placed against the lens 1, so that the first positioning plate 5 and the second positioning plate 6 are offset from the snap-fit ​​plate 2 on the lens 1. When the second positioning plate 6 is against the lens 1, the spring 11 is in a compressed state. Then, the cover 3 is rotated through the auxiliary groove 4, so that the first positioning plate 5 and the second positioning plate 6 are snapped into the snap-fit ​​groove respectively. Because the spring 11 is in a compressed state, the spring 11 generates action force and reaction force. Under the action force and reaction force, the first positioning plate 5 is more closely pressed against the snap-fit ​​groove. The first positioning plate 5 is not easy to separate from the snap-fit ​​groove, and the second positioning plate 6 is also not easy to separate from the snap-fit ​​groove. The cover is stably installed on the lens 1, achieving the effect of making the use of the protective cover more convenient.
