TECHNICAL FIELD

[0001] The present application relates to the technical field of camera lens covers, in particular to a multi-angle limiting camera lens cover. BACKGROUND

[0002] The camera lens cover is an important accessory for protecting the camera lens. The surface of the camera lens is coated with a film, which is fragile. If exposed to the outside world for a long time, it is easy to get dirty. Cleaning the lens may scratch the coating. The camera lens cover reduces the risk of damage to the camera lens.

[0003] The existing camera lens cover includes a lens cover, a lock fixed to the side wall of the lens cover by a bolt, and a clamping ring fixed to the side wall of the lens. The inner wall of the lens cover is integrally fixed with a clamping ring, and the outer wall of the clamping ring is provided with a clamping groove. The clamping ring and the clamping groove can be clamped and matched, that is, the lens cover can be covered on the outside of the clamping ring. When the user uses the camera, the user flips the lens cover. At this time, the lens cover is flipped away from the lens. When the user finishes using the camera, the user controls the lens cover to cover the lens cover on the outside of the clamping ring.

[0004] The above-mentioned lens cover relies on the whole machine to realize angle limiting. When used for a long time, the rotation is easy to wear the appearance of the camera, and there is room for improvement. Content of the utility model

[0005] In order to make the lens cover realize angle limiting, so as to reduce the wear of the camera appearance when the lens cover is used for a long time, the present application provides a multi-angle limiting camera lens cover.

[0006] The present application provides a multi-angle limiting camera lens cover, which adopts the following technical scheme:

A plurality of grooves are formed on one side of the concave wheel close to the cam. The cam can be clamped and matched with the inner wall of the groove. The end of the elastic member abuts against the side wall of the concave wheel.

[0008] By adopting the technical scheme, when a user uses the camera, the user rotates the upper cover, at which time the upper cover drives the shell to rotate on the connecting shaft, the concave wheel rotates on the side wall of the connecting shaft under the torsion of the shell, and the elastic member is compressed by the concave wheel; when the convex wheel and the concave groove are matched, the elastic member pushes the inner wall of the convex wheel and the concave groove to abut, the upper cover is fixed to the side wall of the base, thereby realizing the locking of the upper cover; when the user changes the rotation angle of the upper cover, the above process is repeated, the angle of the mirror cover is limited, thereby reducing the wear of the appearance of the camera when the mirror cover is used for a long time.

[0009] Optionally, the side wall of the convex wheel is fixed with a protrusion, the outer side of the protrusion is provided with a first positioning groove, and the side wall of the concave wheel is provided with a second positioning groove; when the first positioning groove is aligned with the second positioning groove, the upper cover is rotated to a position close to the side wall of the camera lens.

[0012] By adopting the technical scheme, when the concave wheel rotates, one end of the elastic member rotates under the torsion of the concave wheel, and the other end of the elastic member is fixed under the action of the positioning block; when the convex wheel and the concave groove are matched, the rotation trend of the elastic member stops, at which time the elastic member accumulates internal elastic force; when the user rotates the upper cover to move the convex wheel away from the concave groove, the upper cover is quickly returned under the driving action of the elastic member, the setting improves the shifting speed of the upper cover, and improves the user experience of the mirror cover.

[0013] Optionally, the connecting shaft further comprises a screw threadedly fixed to the end of the shaft body away from the convex wheel and a snap spring fixed to the side wall of the shaft body, and the side wall of the snap spring abuts against the outer wall of the shell.

[0014] By adopting the technical scheme, the setting of the screw and the snap spring improves the stability of the connecting shaft when fixed to the side wall of the base, reduces the possibility of shaking of the connecting shaft during rotation of the upper cover, and thereby improves the stability of the mirror cover during use.

[0015] Optionally, the side wall of the shaft body is arranged in a plane, and the inner wall of the positioning block is clamped and fixed to the side wall of the shaft body.

[0018] By adopting the technical scheme, the cooperation of the threaded hole and the screw improves the stability of the connecting shaft fixed to the side wall of the limiting block, the clamping cooperation of the special-shaped hole and the clamping surface reduces the possibility of rotation of the cam during use of the mirror cover, thereby improving the accuracy during rotation of the cover body, and the user experience is further improved.

[0019] Optionally, the upper cover comprises a connecting cylinder fixed to the side wall of the shell and a cover body fixed to the outer wall of the connecting cylinder, and the inner wall of the connecting cylinder is clamped and fixed with the outer wall of the shell.

[0020] By adopting the technical scheme, the clamping and fixing mode of the connecting cylinder and the shell improves the connection stability between the upper cover and the shell, reduces the possibility of sliding of the upper cover during use, and the clamping fixing mode is convenient for workers to install the upper cover, thereby improving the efficiency of workers in assembling the mirror cover.

[0021] Optionally, the side wall of the cover body is provided with an expansion hole, the side of the cover seat close to the cover body is provided with a mounting groove, the side wall of the cover seat is provided with a through hole, and the inner diameter of the through hole is greater than the inner diameter of the expansion hole.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. When the user uses the lens cover, the user rotates the top cover, causing the housing to rotate. The concave wheel rotates on the side wall of the connecting shaft under the action of the housing rotation. At this time, the elastic element is compressed under the action of the concave wheel. As the concave wheel rotates, the cam engages with the inner wall of the groove. Under the thrust of the elastic element, the cam abuts against the inner wall of the groove. At this time, the positioning and locking of the top cover is achieved. When the user changes the angle of the top cover, the above process is repeated. This setting enables the lens cover to achieve angle limit, thereby reducing the wear and tear on the camera's appearance when the lens cover is used for a long time.

[0025] 2. The design of the first and second positioning grooves facilitates accurate positioning of the relative positions of the cam and the concave wheel when installing the lens cover, thereby increasing the work efficiency of the staff when installing the lens cover and further improving the accuracy of the user when using the lens cover.

[0026] 3. The fit between the screw and the threaded hole improves the stability of the shaft when working on the side wall of the limit block, and the fit between the irregular hole and the snap-fit ​​surface further reduces the possibility of the shaft shaking on the side wall of the limit block, thereby improving the accuracy of the mirror cover and enhancing the user experience.

DETAILED DESCRIPTION

[0035] The following will be described in detail with reference to the accompanying drawings Figures 1-7 The application is further described in detail.

[0036] The application discloses a multi-angle limiting camera lens cover.

[0037] Referring to Figure 1 and Figure 6 A multi-angle limiting camera lens cover, comprising a cover seat 1, a base 2 fixed to the side wall of the cover seat 1, a connecting shaft 3 fixed to the side wall of the base 2, a cam 4 fixed to one end of the connecting shaft 3, a concave wheel 5 rotationally connected to the side of the connecting shaft 3 close to the cam 4, an elastic piece 6 fixed to the side wall of the connecting shaft 3, a shell 7 fixed to the side wall of the concave wheel 5, and an upper cover 8 fixed to the side wall of the shell 7, wherein a plurality of grooves 9 are formed in the side of the concave wheel 5 close to the cam 4, in the embodiment of the application, the grooves 9 are preferably three, and the three grooves 9 correspond to the closed state, 225-degree rotation state and 270-degree rotation state of the upper cover 8, respectively, the side wall of the cam 4 is fixed with a protrusion 10, the protrusion 10 can be clamped and matched with the inner wall of the groove 9, and the end of the elastic piece 6 abuts against the side of the concave wheel 5 away from the cam 4.

[0038] Referring to Figure 1 and Figure 3 The base 2 comprises a plurality of connecting plates 21 fixed to the side wall of the base 2 and limiting blocks 22 fixed to the side wall of the connecting plates 21, in the embodiment of the application, the connecting plates 21 are preferably provided with two, and the corresponding limiting blocks 22 are also provided with two, the distance between the two limiting blocks 22 is the same as the length of the connecting shaft 3, and the side wall of one of the limiting blocks 22 is provided with a special-shaped hole 14, which is preferably octagonal, the side wall of the cam 4 is provided with two clamping surfaces 15, which are located on the opposite sides of the cam 4, the clamping surface 15 abuts against the inner wall of the special-shaped hole 14, so that the limiting block 22 is clamped and fixed with the cam 4.

[0039] Referring to Figure 2 and Figure 4A threaded hole 13 is provided on the side wall of the limiting block 22 away from the cam 4. The threaded hole 13 is arranged opposite to the irregular hole 14. The connecting shaft 3 includes a screw 33, which is threaded into the inner wall of the threaded hole 13, thereby fixing the connecting shaft 3 on the limiting block 22. This makes it easy for workers or users to disassemble and install the connecting shaft 3, so as to carry out maintenance or replacement work on the connecting shaft 3. The connecting plate 21 on the side wall of this limiting hole covers part of the threaded hole 13, reducing the possibility of the screw 33 sliding out from the inner wall of the threaded hole 13.

[0040] Reference Figure 5 and Figure 6 The connecting shaft 3 also includes a shaft body 31, a positioning block 32 fixed to the side wall of the shaft body 31, and a retaining spring 34 fixed to the side wall of the shaft body 31. The side wall of the shaft body 31 has two opposing planes. The inner wall of the positioning block 32 abuts against the planes, thus achieving a snap-fit ​​fixation between the positioning block 32 and the shaft body 31. One end of the elastic element 6 is fixed to the side wall of the positioning block 32 near the cam 4, and the other end is fixed to the side wall of the concave wheel 5 away from the cam 4. That is, when the concave wheel 5 rotates, one end of the elastic element 6 is fixed under the action of the positioning block 32, while the other end rotates under the action of the concave wheel 5, making the reset process of the upper cover 8 faster. The retaining spring 34 is located on the side of the shaft body 31 away from the cam 4, and the inner wall of the retaining spring 34 also abuts against the plane, achieving a snap-fit ​​fixation between the retaining spring 34 and the shaft body 31. The side wall of the retaining spring 34 abuts against the side of the housing 7 away from the cam 4, thus fixing the housing 7 and reducing the possibility of the housing 7 sliding on the side wall of the shaft body 31.

[0041] Reference Figure 5 and Figure 7 The side wall of the protrusion 10 is provided with a first positioning groove 11, and the side wall of the concave wheel 5 is provided with a second positioning groove 12. The second positioning groove 12 is located on the side wall of the concave wheel 5 near the groove 9. When the first positioning groove 11 and the second positioning groove 12 are opposite each other, the upper cover 8 is located at a 270-degree rotation position on the side wall of the cover seat 1. This setting allows the staff to accurately position the upper cover 8 when installing the mirror cover, increasing the staff's work efficiency.

[0042] Reference Figure 1 and Figure 7 The upper cover 8 includes a connecting cylinder 81 fixed to the outer wall of the housing 7 and a cover body 82 fixed to the outer wall of the connecting cylinder 81. The inner wall of the connecting cylinder 81 is snapped and fixed to the outer wall of the housing 7. The cover seat 1 has an installation groove 17 on the side near the cover body 82. The side wall of the cover body 82 can abut against the inner wall of the installation groove 17. The side wall of the cover body 82 has an expansion hole 16. The side wall of the cover seat 1 has an installation hole 18. The expansion hole 16 and the installation hole 18 are arranged opposite to each other, and the inner diameter of the expansion hole 16 is smaller than the inner diameter of the installation hole 18.

[0043] The implementation principle of a multi-angle limiting camera lens cover in this application embodiment is as follows: When the user uses the lens cover, the user installs the lens cover to the camera lens position through the mounting hole 18. Then the user rotates the cover body 82. At this time, under the action of the connecting cylinder 81, the housing 7 drives the concave wheel 5 to rotate. The concave wheel 5 compresses the elastic element 6. When the protrusion 10 approaches the inner wall of the groove 9, the elastic element 6 pushes the concave wheel 5 to abut against the cam 4. The cover body 82 is positioned and locked to the side wall of the cover seat 1. When the user changes the angle of the cover body 82 on the cover seat 1, the above process is repeated. When the user resets the cover body 82, the stress accumulated at the end of the elastic element 6 away from the positioning block 32 drives the concave wheel 5 to rotate quickly to reset the cover body 82. This setting enables the lens cover to achieve angle limiting, thereby reducing the wear and tear on the camera appearance when the lens cover is used for a long time.

[0044] The above are all 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.
