Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lens fixing devices, in particular to a double fisheye lens fixing device. Background Art
[0002] A dual fisheye lens is a special photographic lens that has two independent fisheye lens units. These lenses are usually used to shoot images with a wide angle of view and can capture a wider field of view than traditional lenses. This lens design allows photographers or videographers to obtain a wider angle of view when shooting, thereby capturing more details of the scene. Dual fisheye lenses are often used in professional photography and filmmaking, as well as virtual reality (VR) video shooting, because they can provide a nearly spherical field of view, making the audience feel as if they are in the shooting scene. However, when installing existing dual fisheye lenses, they still use the traditional lens mounting method. The installation angle is prone to slight deviations, which makes it impossible for the two lenses inside the dual fisheye lens to be aligned with the lens of the camera, and the captured image will also be deviated. Therefore, a dual fisheye lens fixing device is designed to solve the above problem. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-4 The utility model provides a technical solution: a dual fisheye lens fixing device, comprising: a camera body 1, a front surface of the camera body 1 is provided with an overall annular adjustment ring 2, the outer diameter of the front section of the adjusting ring 2 is larger than the outer diameter of the rear section, the rear end of the adjusting ring 2 is connected to the inside of the camera body 1 through a bearing, the front end of the adjusting ring 2 is provided with a stopper 3 with a threaded outer side, the stopper 3 is connected to the inner side of the adjusting ring 2 through a thread, the front end of the stopper 3 is provided with a clamping block 4, the rear end of the clamping block 4 is fixedly connected to the inside of the camera body 1, the front end of the clamping block 4 is provided with a clamping groove 5, the height of the stopper 3 is the same as the distance between the bottom of the clamping block 4 and the lower end of the clamping groove 5, the front end of the clamping block 4 is provided with a dual fisheye lens 6, the rear surface of the dual fisheye lens 6 is connected with an annular clamping claw 7, the clamping claw 7 is inserted into the inside of the clamping groove 5, the three clamping claws 7 have the same shape, and the three clamping grooves 5 also have the same shape.
[0024] When in use, first move the block 3 to the bottom of the installation location inside the front end of the camera body 1. At this time, align the claw 7 at the rear end of the double fisheye lens 6 with the corresponding inner space between the blocks 4. Then rotate the double fisheye lens 6. The claw 7 will be inserted into the inside of the card slot 5. At this time, rotate the adjustment ring 2. The inner side of the adjustment ring 2 is connected to the outer side of the block 3 through a thread. When the adjustment ring 2 rotates, the outer side will be blocked by the block 4, which will cause the block 3 to move axially. When the block 3 is moved until the front end of the block 3 is parallel to the front end of the block 4, one side of the block 3 will block one end of the claw 7 to prevent the claw 7 from sliding inside the card slot 5.
[0025] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a slot 21 is opened on the outer side of the front end opening of the adjustment ring 2, a baffle 22 is fixedly connected to the outer side of the front surface of the claw 7, and a sealing ring is connected to the outer side of the baffle 22. The baffle 22 is inserted and connected to the slot 21.
[0026] From the analysis of the above structure, it can be seen that when the dual fisheye lens 6 is inserted into the front surface of the camera body 1, the baffle 22 will be inserted into the inside of the slot 21, and the sealing ring will press against the inner side of the slot 21 to improve the sealing and prevent rainwater and mud and sand from entering the connection between the dual fisheye lens 6 and the camera body 1.
[0027] like Figure 1-2 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, the shape of the stopper 3 is the same as the shape of the corresponding clamping block 4, and the shape and angle of each stopper 3 and clamping block 4 are different.
[0028] From the analysis of the above structure, it can be seen that the shapes and angles of each stopper 3 and clamping block 4 are different, so that the clamping claws 7 can only be inserted into the gaps between the clamping blocks 4 when they are aligned with the corresponding clamping claws 7 .
[0029] like Figure 1-2 As shown, the embodiment of the present invention provides an implementation method. Based on the above implementation method, installation points are marked on the lens installation position on the front surface of the camera body 1 and the middle of the upper surface of the double fisheye lens 6.
[0030] From the analysis of the above structure, it can be seen that when installing the dual fisheye lens 6, aligning the two installation points and then inserting it can play a guiding role.
[0031] like Figure 1-3 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, a guiding slope is provided on the front side of the counterclockwise rotating end of the stopper 3, and a guiding slope is also provided on the rear side of the clockwise rotating end of the claw 7.
[0032] From the analysis of the above structure, it can be seen that when the claw 7 is inserted into the interior of the slot 5, if the position is pushed into place, the stop block 3 is pushed at this time, and the slope of the stop block 3 will connect with the slope of the claw 7. While the stop block 3 continues to move forward, the stop block 3 will push the claw 7 completely into the interior of the slot 5.
[0033] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a fixed socket 23 is opened inside the right side of the adjustment ring 2, and a fixed column 24 is provided at the rear end of the right side of the adjustment ring 2. A button 25 is connected to the right side of the fixing column 24, and a spring 26 is connected to the rear end of the button 25. The fixing column 24, the button 25 and the spring 26 are all inserted and connected to the inside of the camera body 1. When the adjustment ring 2 rotates one circle, the stop block 3 will move forward to the position of the front surface of the block 4.
[0034] From the analysis of the above structure, it can be seen that after the claw 7 at the rear end of the double fisheye lens 6 is inserted into the interior of the card slot 5, the button 25 is pressed to drive the fixing column 24 to be pushed backward together, and the fixing column 24 will be pushed out from the interior of the fixed socket 23. After that, after the adjustment ring 2 is rotated one circle, the block 3 will be pushed to the position of the front surface of the block 4. During the rotation, the button 25 is released, and the spring 26 will push the button 25 and the fixing column 24 out. At this time, when the position of the fixing column 24 reaches the position of the fixed socket 23, the button 25 and the fixing column 24 will be completely pushed out and inserted into the interior of the fixed socket 23, so that the position of the adjustment ring 2 is fixed, starting the positioning and preventing the adjustment ring 2 from loosening.
[0035] like Figure 1-4 As shown, an embodiment of the present invention provides an implementation method. Based on the above implementation method, an anti-slip pattern is provided around the outer side of the front section of the adjustment ring 2.
[0036] From the analysis of the above structure, it can be seen that when the adjusting ring 2 is rotated, the anti-slip pattern can provide a certain friction force for the fingers to help the rotation.
