[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This embodiment provides a shooting location positioning device, such as... Figures 1 to 4 As shown, the shooting position positioning device includes a base plate 1, a lifting frame 2 fixedly installed on the top of the base plate 1, and an adjustment mechanism 3 located on the top of the lifting frame 2. It can use a manual screw, electric or pneumatic lifting rod, and its function is to quickly adjust the height of the entire shooting platform to adapt to different shooting scenarios.

[0027] The steering mechanism 3 includes a mounting plate 31, a rotating shaft 32 rotatably connected to the front end of the mounting plate 31, a U-shaped bracket 33 fixedly mounted on the top of the rotating shaft 32, a connecting block 34 fixedly mounted on the lower end of the rotating shaft 32, a groove 36 fixedly connected to the front side of the connecting block 34, a lead screw 37 rotatably connected to the inner side of the groove 36, a moving block 38 threadedly connected to the outer side of the lead screw 37, a diagonal brace 39 hinged to the top of the moving block 38, a first motor 310 fixedly mounted on the rear end of the groove 36, and a mounting block 35 rotatably connected to the inner side of the U-shaped bracket 33 and hinged at the bottom to the top of the diagonal brace 39. Because the lead screw 37 transmission has high precision and self-locking characteristics, it can accurately convert the rotation of the first motor 310 into the linear displacement of the moving block 38, thereby accurately controlling the pitch angle and maintaining it in any position without drifting.

[0028] The front end of the mounting block 35 is equipped with a positioning structure 4 for fixing the shooting equipment, which realizes the non-destructive and quick clamping of "one press to lock and one lift to release", greatly improving work efficiency; the lower end of the connecting block 34 is fixedly installed with a rotating mechanism 5, which ensures the stability and accuracy of the rotation movement, and can realize a wide range of panoramic or tracking shooting.

[0029] In one embodiment, the positioning structure 4 includes a positioning groove 41 at the front end of the mounting block 35, movable cavities 42 on both sides of the positioning groove 41, a support plate 43 at the bottom of the inner side of the positioning groove 41, a pull rod 44 fixedly connected to the center of the bottom of the support plate 43, a first spring 45 connected between the support plate 43 and the inner wall of the positioning groove 41, an L-shaped rod 46 fixedly connected to both ends of the support plate 43 and located inside the movable cavity 42, a wedge block 47 fixedly connected to the top of the L-shaped rod 46, a movable rod 48 penetrating one side wall of the movable cavity 42, a clamping plate 49 fixedly connected to one end of the movable rod 48, a roller 410 rotatably connected to the other end of the movable rod 48 and inclined to the wedge block 47, a limiting plate 411 fixedly connected to one side of the roller 410, and a second spring 412 connected between the limiting plate 411 and the inner wall of the movable cavity 42.

[0030] In this embodiment, refer to Figure 1 Lift the shooting device upwards. The support plate 43 rises under the rebound force of the first spring 45. The wedge block 47 rises through the L-shaped rod 46. Due to the inclined plane, the wedge block 47 no longer squeezes the roller 410. The second spring 412 rebounds, pushing the limit plate 411 and the movable rod 48 to move outwards. The clamping plate 49 is then released, and the device can be easily removed.

[0031] In one embodiment, the rotating mechanism 5 includes a second motor 51 fixedly mounted on the lower end of the connecting block 34, a drive gear 52 fixedly mounted on the output shaft of the second motor 51, and a driven gear 53 fixedly mounted on the lower end of the rotating shaft 32 and meshing with the drive gear 52.

[0032] In this embodiment, refer to Figure 4 The transmission between the driving gear 52 and the driven gear 53 ensures the smoothness and accuracy of the rotational motion, enabling wide-range panoramic or tracking shooting.

[0033] In one embodiment, a slider 471 is fixedly connected to the side of the wedge block 47 away from the movable rod 48, and a slide rail 421 that is slidably connected to the slider 471 is fixedly provided on the inner wall of one side of the movable cavity 42.

[0034] In this embodiment, refer to Figure 2 and Figure 3 The function of slider 471 and slide rail 421 is to ensure that wedge block 47 can only make strictly vertical movements, prevent it from shaking or rotating, and ensure the reliability and stability of the inclined plane transmission mechanism.

[0035] In one embodiment, positioning holes 11 are provided at each of the four corners of the base plate 1.

[0036] In this embodiment, refer to Figure 1It is used to secure the entire device to a workbench, tripod, or mobile platform with bolts to prevent accidental movement during adjustment and shooting.

[0037] Working principle: The first motor 310 starts, driving the lead screw 37 to rotate. The rotating lead screw 37 drives the threadedly connected moving block 38 to move horizontally back and forth along the inner side of the groove 36. The moving block 38 pushes or pulls the bottom of the mounting block 35 through the diagonal brace 39. Both ends of the diagonal brace 39 are hinged, forming a linkage mechanism. When the moving block 38 moves forward, the diagonal brace 39 pushes up the bottom of the mounting block 35, pressing down its front end, achieving a downward angle for shooting. When the moving block 38 moves backward, the diagonal brace 39 pulls the bottom of the mounting block 35 backward, raising its front end, achieving an upward angle for shooting. Because the lead screw 37 transmission has high precision and self-locking characteristics, it can accurately convert the rotation of the first motor 310 into the linear displacement of the moving block 38, thereby precisely controlling the pitch angle and maintaining it in any position without drifting.

[0038] The second motor 51 starts, driving the drive gear 52 to rotate. The drive gear 52 meshes with the driven gear 53 fixed to the lower end of the rotating shaft 32, thereby transmitting power to the rotating shaft 32. The rotating shaft 32 drives the entire mounting block 35 and the positioning structure 4 to rotate 360° horizontally around the axis of the rotating shaft 32 via the U-shaped bracket 33. The gear transmission ensures the smoothness and accuracy of the rotational motion, enabling wide-range panoramic or tracking shooting.

[0039] The positioning structure 4 enables quick clamping and release, requiring no tools, and allows for rapid and stable clamping or releasing of the shooting equipment. The process is as follows: Place the base of the shooting equipment downwards into the positioning groove 41 and press the equipment so that its bottom presses against the support plate 43. The support plate 43 moves downwards under pressure, compressing the first spring 45, and simultaneously moving the bottom pull rod 44 and the two lower L-shaped rods 46 downwards together. The wedge block 47 at the top of the L-shaped rod 46 descends accordingly. Due to the pre-push force of the second spring 412, the roller 410 at one end of the movable rod 48 remains in close contact with the inclined surface of the wedge block 47. As the wedge block 47 (inclined surface downwards) descends, the inclined surface squeezes the roller 410. This squeezing overcomes the force of the second spring 412, pushing the entire movable rod 48 horizontally towards the center of the positioning groove 41, thereby tightening the clamping plate 49 at the other end, firmly clamping the body of the shooting equipment from both sides.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
