Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a novel zoom camera structure. Background Technology

[0002] A camera generally has basic functions such as video recording / transmission and still image capture. It captures images through a lens, and then the photosensitive components and control components inside the camera process the images and convert them into digital signals that can be recognized by a computer. The images are then input to a computer via a parallel port or USB connection, and the software then restores the images.

[0003] Currently, existing cameras have an autofocus device inside before shooting objects, which improves the camera's adaptability. However, after focusing, the front exposure angle of the camera does not change accordingly, which affects the image quality during shooting. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides a novel zoom camera structure. The basic concept of the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows:

[0005] A novel zoom camera structure includes an end collar. A docking ring is fixed to the top of the end collar near the outer edge of its outer surface. An annular transmission cavity is formed inside the end collar. Multiple mounting slots are equidistantly formed along the circumferential direction on the inner sidewall of the end collar. All of the mounting slots extend into the interior of the annular transmission cavity. A rotating shaft is rotatably mounted inside each of the mounting slots. Light-blocking discs are fixed to the outer surface of one side of each of the rotating shafts. All of the light-blocking discs are located inside the end collar.

[0006] Optionally, the plurality of light-blocking discs are circumferentially distributed on the inner side of the end collar, and two adjacent light-blocking discs are attached to each other on opposite sides.

[0007] Optionally, the outer surface of the docking ring is provided with an annular groove, and a plurality of positioning bolts are provided at equal intervals along the circumferential direction on one side of the inner wall of the annular groove.

[0008] Optionally, an annular sleeve is fitted onto the outer surface of the mating ring, and one end of each of the plurality of positioning bolts extends to the inner side of the mating ring.

[0009] Optionally, a side opening is provided on one outer surface of the end collar, the side opening extending into the interior of the annular transmission cavity, and a transmission ring is provided inside the annular transmission cavity.

[0010] Optionally, the outer surface of the transmission ring is provided with a transmission gear ring, and the inner wall of the transmission ring is fixed with multiple rack patches at equal intervals along the circumferential direction.

[0011] Optionally, each of the multiple rotating shafts has multiple teeth on its other side, and each of the multiple teeth meshes with the rack patch.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. In this utility model, in actual use, the end collar is first installed at the end of the camera. Then, since the light-blocking discs are distributed on the inner side of the end collar, the light-blocking discs can be used to adjust the light-blocking intensity at the end of the camera. During adjustment, the transmission ring rotates, causing the rack patch to mesh with the teeth on the rotating shaft, thereby driving the rotating shaft to rotate and adjust the opening and closing angle of the light-blocking discs, thereby changing the amount of light blocked.

[0014] 2. In this utility model, an annular groove is opened on the outer surface of the docking ring, and a positioning bolt is set inside the annular groove so that it can be fixed by the positioning bolt after docking with the camera. Then, the annular groove is covered by an annular sleeve, which is beneficial to the flatness of the overall appearance and can protect the connection part of the positioning bolt to prevent water from splashing to the docking point. A side opening is opened on the outer surface of the end sleeve and extends into the annular transmission cavity, which helps the external drive device to dock and drive the transmission ring.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, such as Figure 1-4 As shown, this utility model provides a novel zoom camera structure technical solution: including an end collar 1, a docking ring 2 fixed at the top of the end collar 1 near the outer edge of the outer surface, an annular transmission cavity 8 opened inside the end collar 1, and multiple mounting grooves 12 equidistantly opened along the circumferential direction on the inner side wall of the end collar 1, all of the multiple mounting grooves 12 penetrating into the interior of the annular transmission cavity 8, and a rotating shaft 10 rotatably arranged inside each of the multiple mounting grooves 12, and light-blocking discs 4 fixed on one outer surface of each of the multiple rotating shafts 10, all of the multiple light-blocking discs 4 being located inside the end collar 1.

[0025] The effect achieved by the entire embodiment 1 is that, in actual use, the end collar 1 is first installed at the end of the camera. Then, since the light-blocking discs 4 are distributed on the inner side of the end collar 1, the light-blocking discs 4 can be used to adjust the light-blocking intensity at the end of the camera. During adjustment, the transmission ring 6 rotates, causing the rack patch 9 to mesh with the teeth 11 on the rotating shaft 10, thereby driving the rotating shaft 10 to rotate and adjust the opening and closing angle of the light-blocking discs 4, thereby changing the amount of light blocked.

[0026] Example 2, as Figure 1-4 As shown, multiple light-blocking discs 4 are circumferentially distributed on the inner side of the end collar 1, and two adjacent light-blocking discs 4 are attached to each other on opposite sides. An annular groove 13 is provided on the outer surface of the docking ring 2. Multiple positioning bolts 14 are equidistantly arranged along the circumferential direction on one side of the inner wall of the annular groove 13. An annular sleeve 5 is fitted on the outer surface of the docking ring 2. One end of each positioning bolt 14 extends to the inner side of the docking ring 2. A side opening 3 is provided on one side of the outer surface of the end collar 1. The side opening 3 penetrates into the interior of the annular transmission cavity 8. A transmission ring 6 is provided inside the annular transmission cavity 8. A transmission gear ring 7 is provided on the outer surface of the transmission ring 6. Multiple rack patches 9 are fixed equidistantly along the circumferential direction on the inner wall of the transmission ring 6. Multiple teeth 11 are provided on the other side of each of the multiple rotating shafts 10. The multiple teeth 11 are all meshed with the rack patches 9.

[0027] The overall effect of embodiment 2 is that an annular groove 13 is opened on the outer surface of the docking ring 2, and a positioning bolt 14 is set inside the annular groove 13 so that it can be fixed by the positioning bolt 14 after docking with the camera. Then, the annular groove 13 is covered by the annular sleeve 5, which is beneficial to the flatness of the overall appearance and can protect the connection part of the positioning bolt 14 to prevent water from splashing to the docking point. A side opening 3 is opened on the outer surface of the end sleeve 1 and the side opening 3 extends into the annular transmission cavity 8, which helps the external drive device to dock and drive the transmission ring 6.

[0028] Working principle: In actual use, the end collar 1 is first installed at the end of the camera. Since the light-blocking discs 4 are distributed on the inner side of the end collar 1, the light-blocking discs 4 can be used to adjust the light-blocking intensity at the end of the camera. During adjustment, the transmission ring 6 rotates, causing the rack patch 9 to mesh with the teeth 11 on the rotating shaft 10, thereby driving the rotating shaft 10 to rotate and adjust the opening angle of the light-blocking discs 4, thus changing the amount of light blocking. An annular groove 13 is opened on the outer surface of the docking ring 2, and a positioning bolt 14 is set inside the annular groove 13 so that it can be fixed by the positioning bolt 14 after docking with the camera. Then, the annular sleeve 5 covers the annular groove 13, which is beneficial to the flatness of the overall appearance and can protect the connection part of the positioning bolt 14 to prevent water from splashing to the docking point. A side opening 3 is opened on the outer surface of the end collar 1 and extends into the annular transmission cavity 8, which helps the external drive device to dock and drive the transmission ring 6.
