Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a positioning platform for a photographic support. Background Technology

[0002] As a crucial auxiliary device in film and television shooting, still photography, and live streaming, the core function of a camera rig is to provide stable and precise support for various photographic equipment through a positioning platform. This platform typically features positioning posts that mate with standard holes on the bottom of the equipment to enable rapid installation and alignment. However, with the diversification and specialization of photographic equipment, the layout of the positioning holes varies significantly due to differences in functional requirements. Traditional positioning platforms, with their fixed positioning post positions, struggle to adapt to multiple equipment types, leading to frequent platform changes or the need for customized adapters, severely hindering shooting efficiency and equipment versatility. Therefore, a new positioning platform capable of quickly switching positioning post positions is urgently needed to improve the adaptability of camera rigs to different photographic equipment. Utility Model Content

[0003] The purpose of this invention is to provide a positioning platform for a photography bracket, which solves the problem of poor adaptability of traditional positioning platforms to different photography equipment.

[0004] The present invention provides the following technical solution: a positioning platform for a photographic bracket, comprising a positioning platform, a first positioning post, a second positioning post, and a switching mechanism disposed on the positioning platform. The first positioning post and the second positioning post are movably disposed along the height direction. The switching mechanism includes a switching slider movably disposed on the lower side of the first positioning post and the second positioning post. The switching slider is provided with a first inclined surface and a second inclined surface disposed opposite to each other. The positioning platform is provided with a table surface for the first positioning post and the second positioning post to pass through. When the switching slider moves, the first inclined surface continuously abuts against the first positioning post, and the second inclined surface continuously abuts against the second positioning post, so that the first positioning post and the second positioning post alternately extend out of the table surface.

[0005] As described above, in a positioning platform for a camera bracket, the first inclined surface and the second inclined surface are arranged in a V-shape with relative inclination, such that when the switching slider moves closer to the first positioning post, the second inclined surface pushes out the second positioning post through a wedge engagement, and when the switching slider moves closer to the second positioning post, the first inclined surface pushes out the first positioning post through a wedge engagement.

[0006] As described above, in a positioning platform for a photographic bracket, the switching mechanism further includes a return spring sleeved on the first positioning post and the second positioning post, the upper side of the return spring pressing against the positioning platform, and the lower side of the return spring pressing against the first positioning post or the second positioning post.

[0007] As described above, a positioning platform for a photographic bracket includes a first positioning post with a first through-part passing through the table surface and a first abutting part for abutting the return spring. The second positioning post includes a second through-part passing through the table surface and a second abutting part for abutting the return spring. The lower side of the first abutting part is provided with a first abutting arc surface corresponding to the first inclined surface, and the lower side of the second abutting part is provided with a second abutting arc surface corresponding to the second inclined surface.

[0008] As described above, a positioning platform for a camera bracket includes a first top surface, a second top surface, and a recessed surface on the upper side of the switching slider. The recessed surface is connected between the first inclined surface and the second inclined surface, the first top surface is connected to the top of the first inclined surface, and the second top surface is connected to the top of the second inclined surface.

[0009] As described above, in a positioning platform for a camera bracket, the lower side of the switching slider is provided with a toggle part.

[0010] As described above, in a positioning platform for a camera bracket, the height of the sunken surface is lower than that of the first and second top surfaces, and the heights of the first and second top surfaces are flush.

[0011] As described above, a positioning platform for a camera bracket has a mounting groove on the underside of the platform, and a switching slider is movably disposed in the mounting groove along the length of the positioning platform.

[0012] As described above, a positioning platform for a camera bracket further includes a slider block surrounding the opening of the mounting groove. The side of the switching slider has a limiting protrusion, and the slider block abuts against the limiting protrusion to prevent the switching slider from disengaging from the mounting groove.

[0013] As described above, a positioning platform for a photographic bracket has a pair of through holes on the table surface located on the upper side of the mounting slot, wherein the first through hole and the second through hole are respectively movably connected to the through hole.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model discloses a positioning platform for a photography bracket. The platform employs a switching mechanism to allow the alternating extension of a first positioning post and a second positioning post. Specifically, the switching mechanism includes a movable switching slider with opposing first and second inclined surfaces. The first inclined surface continuously abuts against the lower side of the first positioning post as the switching slider moves, and the second inclined surface continuously abuts against the lower side of the second positioning post. This allows one positioning post to be pushed out onto the platform as the abutment height of the corresponding inclined surface gradually increases, while the other positioning post retracts below the platform as the abutment height of the corresponding inclined surface gradually decreases. This enables the positioning platform to switch positioning posts by sliding the switching slider back and forth and utilizing the abutment action of the inclined surfaces. This significantly improves the adaptability of the positioning platform to various types of photographic equipment, making the fixing of various photographic equipment and photography brackets more convenient and faster.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0023] Example 1: Please refer to the appendix Figure 1 To be continued Figure 5 This embodiment provides a positioning platform for a photography bracket, including a positioning platform 1, a first positioning post 2, a second positioning post 3 and a switching mechanism 4 disposed on the positioning platform 1. The first positioning post 2 and the second positioning post 3 are movably disposed along the height direction. The switching mechanism 4 includes a switching slider 41 movably disposed below the first positioning post 2 and the second positioning post 3. The switching slider 41 is provided with a first inclined surface 411 and a second inclined surface 412 disposed opposite to each other. The positioning platform 1 is provided with a table surface 11 for the first positioning post 2 and the second positioning post 3 to pass through. When the switching slider 41 moves, the first inclined surface 411 continuously abuts against the first positioning post 2 and the second inclined surface 412 continuously abuts against the second positioning post 3, so that the first positioning post 2 and the second positioning post 3 alternately extend out of the table surface 11. The positioning platform for a photography bracket in this embodiment employs a switching mechanism 4 on the positioning platform 1 to achieve the alternating extension of the first positioning post 2 and the second positioning post 3. Specifically, the switching mechanism 4 includes a movable switching slider 41, which has a first inclined surface 411 and a second inclined surface 412 facing each other. The first inclined surface 411 continuously abuts against the lower side of the first positioning post 2 when the switching slider 41 is moving, and the second inclined surface 412 continuously abuts against the lower side of the second positioning post 3 when the switching slider 41 is moving. This allows one positioning post to be pushed out until it extends above the platform as the abutment height of the corresponding inclined surface gradually increases, while the other positioning post returns to its original position below the platform as the abutment height of the corresponding inclined surface gradually decreases. This enables rapid switching of the extension position of the positioning posts on the positioning platform, significantly improving the adaptability of the positioning platform to various types of photographic equipment and making the fixing of various photographic equipment and photography brackets more convenient and faster.

[0024] The first inclined surface 411 and the second inclined surface 412 are arranged in a V-shape with relative inclination. When the switching slider 41 moves closer to the first positioning post 2, the second inclined surface 412 pushes out the second positioning post 3 through a wedge engagement. When the switching slider 41 moves closer to the second positioning post 3, the first inclined surface 411 pushes out the first positioning post 2 through a wedge engagement. By using the V-shaped relative arrangement of the first inclined surface 411 and the second inclined surface 412, when the switching slider 41 moves away from the first positioning post 2, it pushes out the second positioning post 3, while the first positioning post 2 resets; when the switching slider 41 moves away from the second positioning post 3, it pushes out the first positioning post 2, while the second positioning post 3 resets.

[0025] The switching mechanism 4 also includes a return spring 42 sleeved on the first positioning post 2 and the second positioning post 3. The upper side of the return spring 42 presses against the positioning platform 1, and the lower side of the return spring 42 presses against the first positioning post 2 or the second positioning post 3. The arrangement of the return spring 42 makes the reset of the first positioning post 2 or the second positioning post 3 smoother.

[0026] The first positioning post 2 includes a first through part 21 that passes through the table surface 11 and a first abutting part 22 for abutting the return spring 42. The second positioning post 3 includes a second through part 31 that passes through the table surface 11 and a second abutting part 32 for abutting the return spring 42. The lower side of the first abutting part 22 is surrounded by a first abutting arc surface 221 that corresponds to the first inclined surface 411. The lower side of the second abutting part 32 is surrounded by a second abutting arc surface 321 that corresponds to the second inclined surface 412. Under the transition between the first abutting arc surface 221 and the second abutting arc surface 321, the reset of the first positioning post 2 or the second positioning post 3 is smoother.

[0027] The upper side of the switching slider 41 is also provided with a first top surface 413, a second top surface 414 and a sinking surface 415. The sinking surface 415 is connected between the first inclined surface 411 and the second inclined surface 412. The first top surface 413 is connected to the top of the first inclined surface 411 and the second top surface 414 is connected to the top of the second inclined surface 412, so that the switching slider 41 can maintain the extended state more stably.

[0028] The lower side of the switching slider 41 is provided with a toggle part 416, which makes it easy for the operator to adjust the movement of the switching slider 41 by hand.

[0029] The height of the sunken surface 415 is lower than that of the first top surface 413 and the second top surface 414. The heights of the first top surface 413 and the second top surface 414 are flush, which can ensure that the heights of the first positioning post 2 or the second positioning post 3 are consistent when they extend.

[0030] The positioning platform 1 has a mounting groove 12 on the underside of the tabletop 11. The switching slider 41 is movably mounted in the mounting groove 12 along the length of the positioning platform 1. Furthermore, the positioning platform 1 also includes a slider pressing block 13 surrounding the opening of the mounting groove 12. The side of the switching slider 41 has a limiting protrusion 417. The slider pressing block 13 is used to abut against the limiting protrusion 417 to prevent the switching slider 41 from disengaging from the mounting groove 12. The slider pressing block 13 facilitates the installation of the switching slider 41 and prevents the switching slider 41 from accidentally disengaging from the mounting groove 12.

[0031] The positioning platform 1 has a pair of through holes 14 on the table surface 11 located on the upper side of the mounting groove 12. The first through part 21 and the second through part 31 are respectively movably connected to the through holes 14, and the return spring 42 can be set in the through holes 14, so that the cooperation structure between the switching mechanism 4 and the positioning column is more compact.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
