Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 As shown:

[0029] A viewfinder for film and television production comprises a base 1, an electric push rod 2 fixedly connected to the surface of the base 1, and a camera 5 installed above the electric push rod 2.

[0030] In this embodiment: the existing publication (announcement) number: CN217463808U discloses a viewfinder for film and television production; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the shooting angle is often adjusted continuously according to the different shooting contents, but the above-mentioned device can only achieve rough adjustment of the angle, and the adjusted angle cannot be stably fixed, and it is difficult to make subtle adjustments to the shooting angle of the photographic equipment, affecting the shooting effect". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, an angle adjustment mechanism 3 and a direction adjustment mechanism 4 are added to the application document.

[0031] More specifically:

[0032] like Figure 1-Figure 4 As shown:

[0033] In combination with the above content, the angle adjustment mechanism 3 includes a fixed plate 31 fixedly connected to the top of the electric push rod 2 and a fixed frame 32 installed above the fixed plate 31 and having a U-shaped structure. Clamps 35 are arranged on both sides of the camera 5. A first fixed block 34 is fixedly connected to one side of the fixed frame 32 close to the clamp 35. A worm gear 33 is rotatably connected to the inside of the first fixed block 34, and the worm gear 33 and the clamp 35 are fixedly connected. A worm 36 is meshingly connected to the surface of the worm gear 33.

[0034] In this embodiment, when the film and television production viewfinder is in use, the worm gear 33 can be driven to rotate by rotating the worm 36, and then the worm gear 33 drives the camera 5 installed between the two groups of clamping plates 35 to adjust the angle. The worm gear 33 and the worm 36 are self-locking, so that the camera 5 is not easy to shake or deviate after the angle is adjusted, thereby improving the stability of the angle adjustment.

[0035] Going further:

[0036] like Figure 1-Figure 4 As shown:

[0037] In order to facilitate the installation and disassembly of the camera 5, in an optional embodiment: one end of the worm 36 passes through the first fixed block 34 and the interior of the fixed frame 32, and is fixedly connected to the handle arranged on one side of the fixed frame 32; a second fixed block 37 is fixedly connected to the side of the fixed frame 32 away from the first fixed block 34, a moving block 38 is arranged inside the second fixed block 37, and the moving block 38 and the clamping plate 35 are rotatably connected, and a sliding groove is provided on the side of the second fixed block 37 close to the moving block 38; a screw 39 is screwed inside the moving block 38, one end of the screw 39 passes through the interior of the second fixed block 37, and is fixedly connected to the handle arranged on the second fixed block 37.

[0038] In this embodiment: when the camera 5 needs to be installed or disassembled, the moving block 38 can be driven to move by rotating the screw 39, and then the moving block 38 drives the clamping plate 35 on one side to separate from the camera 5, so that the camera 5 can be disassembled, and the camera 5 is placed between the two groups of clamping plates 35, and then the screw 39 is reversed to drive the two groups of clamping plates 35 to clamp the camera 5, thereby completing the installation of the camera 5 and improving the convenience of installing and disassembling the camera 5.

[0039] More specifically:

[0040] like Figure 1-Figure 4 As shown:

[0041] In combination with the above content, a direction adjustment mechanism 4 is provided inside the fixed plate 31, and the direction adjustment mechanism 4 includes a rotating rod 41 rotatably connected to the inside of the fixed plate 31 and a toothed ring 43 fixedly connected to the surface of the rotating rod 41, the rotating rod 41 and the fixed frame 32 are fixedly connected, and a limiting clamping tooth 42 is provided on the side of the fixed plate 31 close to the toothed ring 43; a first tooth plate 44 is symmetrically fixedly connected to the surface of the limiting clamping tooth 42, a second tooth plate 46 is provided between the two groups of first tooth plates 44, one end of the second tooth plate 46 passes through the inside of the fixed plate 31 and extends to the outside of the fixed plate 31, a gear 45 is meshed and connected between the first tooth plate 44 and the second tooth plate 46, and the gear 45 is rotatably connected to the inside of the fixed plate 31; a sliding groove is provided on the side of the fixed plate 31 close to the limiting clamping tooth 42, and a spring 47 is symmetrically fixedly connected between the limiting clamping tooth 42 and the fixed plate 31.

[0042] In this embodiment: when it is necessary to adjust the shooting direction of the camera 5, the two sets of gears 45 can be driven to rotate by pressing the second tooth plate 46, and then the gear 45 will drive the limit tooth 42 to separate from the gear ring 43 through the two sets of first tooth plates 44, and squeeze the spring 47 to contract, release the limit on the gear ring 43, and then the fixed frame 32 can be rotated to drive the rotating rod 41 to rotate, and the shooting direction of the camera 5 can be adjusted. After the adjustment is appropriate, the pressing of the second tooth plate 46 is released, and the limit tooth 42 will be clamped with the gear ring 43 by the elastic force of the spring 47, and the rotating rod 41 is limited, so that the shooting direction angle of the camera 5 can be adjusted according to the shooting requirements, thereby improving the shooting effect.

[0043] Working principle: When the film and television production viewfinder is in use, the worm gear 33 can be driven to rotate by rotating the worm 36, and then the worm gear 33 drives the camera 5 installed between the two groups of clamping plates 35 to adjust the angle, and the worm gear 33 and the worm gear 36 are self-locking. After the angle is adjusted, the camera 5 is not easy to shake or deviate, thereby improving the stability of the angle adjustment. When it is necessary to adjust the shooting direction of the camera 5, the two groups of gears 45 can be driven to rotate by pressing the second tooth plate 46, and then the gear 45 will drive the limiting clamping teeth 42 to separate from the tooth ring 43 through the two groups of first tooth plates 44, and squeeze the spring 47 to contract, release the limit on the tooth ring 43, and then the fixed frame 32 can be rotated to drive the rotating rod 41 to rotate, and the shooting direction of the camera 5 can be adjusted. The camera 5 is then disassembled by placing the camera 5 between the two groups of clamps 35 and then reversing the screw 39 to drive the two groups of clamps 35 to clamp the camera 5. This completes the installation of the camera 5 and improves the convenience of installing and disassembling the camera 5.

[0044] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention to solve the problems raised in the above background technology.
