Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cameras, in particular to a camera outer lens replacement device and method. BACKGROUND

[0002] A wide-angle lens is a photographic lens with a shorter focal length than a standard lens, a larger angle of view than a standard lens, a longer focal length than a fisheye lens, and a smaller angle of view than a fisheye lens. Wide-angle lenses are divided into two types: ordinary wide-angle lenses and super-wide-angle lenses. The overall optical lens of the current wide-angle lens is usually extremely sealed for connection and fixation. It is inconvenient to disassemble and replace the specific lens inside the wide-angle lens, and when replacing the lens alone, the entire unit usually needs to be removed, resulting in excessive time waste during installation and disassembly.

[0003] As disclosed in the patent with application number 202221410483.9, a wide-angle lens optical lens that can be quickly disassembled and assembled includes a first lens cover and a second lens cover. The first lens cover and the second lens cover are connected to each other. A compression ring is provided between the second lens cover and the first lens cover. The buckle groove on one side of the second lens cover is buckled with the buckle on one end of the first lens cover. By fitting the outer connecting thread groove, the inner connecting thread groove, the outer connecting thread, and the inner connecting thread on the inner side of the first lens cover, the connection is rotated and connected to the top. After that, the buckle and the buckle groove are buckled. Since the buckle groove is triangular with a reduced opening at one end, the buckle can be gradually tightened when connected. The connection principle is similar to that of the current computer case cover. In this way, the lens connection is more secure. When disassembling, reverse rotation can make it disconnected.

[0004] The wide-angle lens of the prior art camera is popularized. Since the outer lens of the camera is easily damaged, in order to reduce the use cost of customers, a lens disassembly jig is needed to replace the easily damaged lens exposed outside. Currently, camera lens replacement still needs to be sent to a repair point for repair, which increases the trouble of customers and the after-sales cost, and customers cannot replace the damaged lens by themselves.

DETAILED DESCRIPTION

[0026] The technical solutions in the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application.

[0027] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood in a broad sense, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Referring to Figures 1-3 As shown in the preferred embodiment of the present application, a camera outer lens replacement device for replacing the outer lens of the camera 1 lens includes a support seat 2, a pressure assembly 3, and a wrench 4. The support seat 2 is provided with a clamping groove 21 and a support column 22. The clamping groove 21 is used to place and position the camera 1. The pressure assembly 3 is located on the support column 22. The pressure assembly 3 includes a handle 31, a movable rod 32, a pressure head 33, and a compression spring 34. The upper end of the movable rod 32 is connected to the handle 31, and the lower end is connected to the pressure head 33. The support column 22 is provided with a threaded hole through which the movable rod 32 passes. The movable rod 32 is provided with a thread 35 matched with the threaded hole. Rotating the handle 31 can make the movable rod 32 move up and down along the threaded hole. The upper end of the compression spring 34 is connected to the support column 22, and the lower end is connected to the pressure head 33. When the pressure head 33 is on top of the outer lens, the compression spring 34 applies a predetermined pressure to the pressure head 33 to press the outer lens tightly. The wrench 4 is used to unscrew the front cover 11 of the camera 1 lens.

[0029] The camera outer lens replacement device of the present application includes a support seat 2, a pressure assembly 3, and a wrench 4. When the user manually replaces the easily damaged outer lens by himself, the camera 1 is placed on the support seat 2, and the camera 1 is positioned by the clamping groove 21. Since the position of the lens inside is easily affected when the front cover 11 of the camera 1 is removed, the optical structure is damaged, therefore, the lens needs to be fixed by the pressure assembly 3. The movable rod 32 is connected to the handle 31 and the pressure head 33 respectively. By rotating the handle 31, the movable rod 32 is moved downward to release the compression spring 34 and the pressure head 33. By the compression spring 34 and the pressure head 33, a predetermined pressure is applied to the outer lens. When the front cover 11 is removed, the internal structure of the lens can be ensured not to change. After replacing the lens, the compression spring 34 and the pressure head 33 apply a predetermined pressure to the outer lens to ensure that the lens is installed flat. Then the front cover 11 is reinstalled, which will not damage the optical structure, and ensure the stability of the overall structure of the camera 1.

[0039] Step 1, place the camera 1 in the clamping groove 21 and make the camera 1 clamped by the clamping groove 21; clamp the camera 1 in the clamping groove 21, and adjust to the appropriate position by moving the camera 1 forward and backward;

[0040] Step 2, rotate the handle to make the movable rod 32 move downward until the movable rod 32 is separated from the pressing head 33; rotate the handle, and the movable rod 32 moves downward under the action of the screw thread 35 and the screw hole, so that the bottom of the movable rod 32 no longer clamps the pressing head 33, and the pressing head 33 moves downward under the action of the compression spring 34 and is in contact with the outer lens;

[0041] Step 3, the pressing head 33 is completely pressed on the upper surface of the outer lens under the action of the compression spring 34, the front cover 11 of the camera 1 lens is unscrewed and removed by the wrench 4; the pressing head 33 is completely pressed on the upper surface of the outer lens, the predetermined pressure output by the compression spring 34 acts on the outer lens, the internal structure of the lens is prevented from moving, and then the front cover 11 is unscrewed by the wrench 4;

[0042] Step 4, rotate the handle to make the movable rod 32 move upward, so that the pressing head 33 is separated from the outer lens, the outer lens is automatically pressed out under the action of the internal pressure of the lens, the outer lens is removed, and a new outer lens is replaced; after the front cover 11 is removed, the handle is rotated to loosen the pressing head 33, when the outer lens is not subjected to pressure, the outer lens is pressed out by the internal pressure, and then the outer lens can be removed and replaced;

[0043] Step 5, rotate the handle to make the movable rod 32 move upward, the pressing head 33 is completely pressed on the upper surface of the new outer lens under the action of the compression spring 34, and the front cover 11 is screwed on the camera 1 lens by the wrench 4. After the new outer lens is rotated, in order to ensure that the outer lens is installed in place, the predetermined pressure is applied to the outer lens by the pressing head 33 and the compression spring 34, the outer lens is installed flat under the action of the pressing head 33, and then the front cover 11 is installed by the wrench 4, and the whole replacement process is completed.
