Technical Field

[0001] This utility model relates to the field of camera lens technology, specifically to an automatic clamping lens support device. Background Technology

[0002] Also known as a camera lens, camera, film camera, and television camera, it is an optical component used for imaging. Its main function is to project external objects onto the image plane through the lens optical system, thereby obtaining a clear image. The basic structure consists of lens elements, lens frame, lens barrel, aperture, focusing mechanism, and camera body. Some lenses also have a shutter in the center. Most modern lens groups consist of 3-7 lens elements, and the structural form varies depending on the number of lens elements. According to the different ways of connecting the lens to the camera body, it can be divided into fixed lenses and interchangeable lenses; according to the different focal lengths and field of view, it can be divided into wide-angle lenses, fisheye lenses, standard lenses, telephoto lenses, and zoom lenses. To meet the needs of various special photography, there are also special photography lenses, such as infrared, ultraviolet, and underwater photography lenses. To increase the light transmission capability of the lens group and meet the needs of special photography, anti-reflective coatings of different colors are often coated on the lens surface.

[0003] The above-mentioned technical conditions also have shortcomings: the existing lens support device requires adjustment of many parts in order to clamp lenses of different diameters, which reduces the effectiveness of the support device.

[0025] 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.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] An automatic clamping lens support device includes an outer frame 1. A first positioning rod 2 is fixedly connected to the top inner side of the outer frame 1. Second positioning rods 3 are fixedly connected to the bottom sides of both sides of the outer frame 1. An upper sleeve 4 is slidably connected to the first positioning rod 2. Lower sleeves 5 are slidably connected to both sets of second positioning rods 3. Positioning sleeves 6 are fixedly connected to the upper sleeve 4 and both sets of lower sleeves 5. Flipping rods 8 are rotatably connected to both sides of the outer wall of the upper sleeve 4. Two sets of vertical rods 9 are fixedly connected to the inner side of the outer frame 1 and to both sides of the first positioning rod 2. A rotating shaft 10 is rotatably connected between the two sets of vertical rods 9. Both sets of flipping rods 8 are provided with relief grooves 13, and the rotating shaft 10 is set inside the relief grooves 13, so that the flipping rod 8 is restricted by the rotating shaft 10 when it deflects, thereby changing the angle and driving the upper sleeve 4 to move. Pulling rods 14 are rotatably connected to one side of the outer wall of both sets of lower sleeves 5. Driving rods 11 are provided on both sides inside the outer frame 1. One end of the flipping rod 8 is rotatably connected to the driving rod 11 on the same side, and one end of the pulling rod 14 is rotatably connected to the driving rod 11 on the same side. When the driving rod 11 slides, the movement of the pulling rod 14 and the flipping rod 8 can be controlled simultaneously.

[0028] Furthermore, pressing blocks 12 are fixedly connected to the outer sides of both sets of drive rods 11 to facilitate operation of the drive rods 11 and thus make them easier to use.

[0029] Furthermore, a synchronizing rod 15 is rotatably connected between the two sets of pressing blocks 12. When the synchronizing rod 15 is pressed, the two sets of pressing blocks 12 can move synchronously. At this time, the rotatable connection allows the angle between the pressing block 12 and the synchronizing rod 15 to change without affecting the use effect.

[0030] Furthermore, a protective pad 7 is fixedly installed on the positioning sleeve 6, which can provide better positioning support for the lens.

[0031] Furthermore, a return spring 16 is fixedly connected to the bottom of the inner wall of the upper sleeve 4. One end of the return spring 16 is fixedly connected to one end of the first positioning rod 2. The same return spring 16 is also provided between the lower sleeve 5 and the second positioning rod 3. It is used for the reset between the sleeve and the positioning rod, so that the positioning sleeve 6 can be reset quickly.

[0032] The implementation principle of this embodiment is as follows: When in use, pressing the synchronizing rod 15 causes both sets of pressing blocks 12 to move downwards, thereby simultaneously driving both sets of driving rods 11 to move. Then, one end of each set of flipping rods 8 moves downwards, and through the action of the rotating shaft 10, the other end of the flipping rod 8 moves upwards, thereby driving the upper sleeve 4 to move upwards. At the same time, the two sets of pulling rods 14 pull the two sets of lower sleeves 5 downwards, causing the three sets of positioning sleeves 6 to separate. Then, the lens that needs to be clamped and positioned is placed inside the three sets of positioning sleeves 6. Then, the synchronizing rod 15 is released, and under the action of the three sets of return springs 16, the three sets of sleeves are reset respectively. Then, the lens is clamped and positioned by the three sets of positioning sleeves 6 and the protective pad 7, which facilitates subsequent use.
