Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a turntable device for achieving precise angle rotation and indexing positioning of a camera during photography. Specifically, it is a photographic indexing turntable with 18 indexing levels, adjustable touch sensitivity, and suitable for various shooting scenarios. Background Technology

[0002] In professional photography, especially for tasks such as panoramic photo stitching, architectural photography, and large group photos, indexing turntables are often required to achieve precise camera positioning and angle adjustment. Various indexing turntables exist in the current technology, typically using a spring-loaded locating pin (such as a ball screw) that engages with a series of locating holes or grooves on the turntable to achieve rotational positioning at different levels.

[0003] However, indexing rotary tables currently on the market generally suffer from one or more of the following technical defects: 1. Fixed and Unique Positioning Sensitivity: Current technology generally uses standard ball screws fixed by internal spring force as positioning components. The positioning sensitivity (i.e., the feedback force and sound when the positioning pin engages the positioning hole) of this design is fixed and unchanging. This cannot meet the personalized operating preferences of different photographers. For example, some users prefer a crisp, strong feedback when shifting gears, while others prefer a smoother, more gentle feel. When operating in special environments such as while wearing gloves, the fixed, weak tactile feedback may also make it difficult for the operator to confirm whether the positioning is accurate.

[0004] 2. Poor material durability: Some core positioning structural components of the indexing rotary table, such as positioning screws and main body threads, are made of ordinary steel or directly tapped on the aluminum alloy body. After long-term and frequent use, they are prone to wear, deformation or even breakage, resulting in decreased positioning accuracy, short service life and increased replacement and maintenance costs for users.

[0005] 3. Insufficient structural stability: Some products sacrifice structural stability in pursuit of lightweight design, resulting in a small base diameter and high center of gravity. When bearing heavy professional cameras and lenses, these products are prone to wobbling, affecting the clarity of the captured images.

[0006] 4. Insufficient expandability and design convenience: The number and location of accessory installation interfaces provided by existing turntables are limited, making it difficult to meet diverse equipment installation needs. Furthermore, some quick-release plates are poorly designed, obstructing the battery compartment or data interface after the camera is installed, causing inconvenience during shooting operations.

[0007] 5. Rigid design concepts: Many designs are dedicated to achieving the switching of multiple indexing levels by setting multiple sets of different numbers of positioning holes. Although this increases the selection of levels, it also makes the structure more complex and does not solve the core user experience problems such as fixed tactile feel and insufficient durability.

[0008] Chinese patent "Multi-position indexing table of panoramic gimbal and its adjustment method", publication number CN106224716A, publication date 2016.12.14, discloses a multi-position indexing table of panoramic gimbal and its adjustment method. The multi-position indexing table of panoramic gimbal includes an indexing table clamp, an indexing table rotating seat, a rotating seat inner core, and an indexing table base. The outer side of the rotating seat inner core is clearance-fitted with the inner side of the indexing table rotating seat, allowing the indexing table rotating seat to rotate relative to the rotating seat inner core. The outer side of the rotating seat inner core is provided with m rows of positioning recesses. The side of the indexing table rotating seat is provided with m main positioning screw holes, m auxiliary positioning screw holes, and 1 rotating seat locking screw hole. It also includes a main positioning ball screw knob, an auxiliary positioning ball screw knob, and a rotating seat locking screw knob that respectively match the main positioning screw holes, auxiliary positioning screw holes, and rotating seat locking screw hole. However, some photographers prefer a clear, responsive feel to the gear shifts, while others may prefer a smoother, more gentle transition and dislike significant abrupt changes. CN106224716A cannot meet these differing needs.

[0009] In summary, existing indexing rotary tables have significant shortcomings in terms of personalized user experience, structural durability, and overall stability. There is an urgent need for a new type of indexing rotary table that can provide adjustable positioning tactile feedback while also ensuring stability, durability, and ease of operation. Utility Model Content

[0010] The purpose of this invention is to solve the technical problems of indexing turntables in the prior art, such as fixed and monotonous positioning touch, poor user experience, easy wear, insufficient stability, and weak expandability.

[0011] To address this, the present invention provides an adjustable tactile indexing turntable for multi-scene photography. It employs an adjustable tactile positioning component, allowing users to customize the intensity of tactile feedback when switching gears. Combined with a series of optimized structural designs and material selections, the durability, stability, and ease of operation of the turntable are comprehensively improved.

[0012] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-scene photography indexing turntable with adjustable tactile feedback includes: Indexing table base; An inner core is connected to the top of the indexing table base; the outer circumference of the inner core is provided with multiple indexing and positioning parts. A rotating assembly, which is sleeved outside the inner core and rotatably connected to the inner core; A clamping assembly is provided on the rotating assembly; An adjustable tactile positioning component is mounted on the rotating component corresponding to the indexing positioning part and selectively cooperates with the indexing positioning part to achieve indexing positioning. The adjustable tactile positioning component includes a hollow threaded sleeve, a positioning pin that can move axially within the threaded sleeve, a spring disposed within the threaded sleeve and applying an elastic thrust to the positioning pin, and an adjustment mechanism for adjusting the compression of the spring; the hollow threaded sleeve is threadedly connected to the outer periphery of the rotating component; by operating the adjustment mechanism to change the preset elastic thrust of the spring, the tactile intensity generated when the positioning pin engages with the indexing positioning part can be adjusted.

[0013] The core advantage of this invention lies in its innovative adjustable tactile positioning component, which transforms the fixed and unchangeable positioning tactile feedback of traditional indexing turntables into a personalized experience that users can freely set according to their preferences. This greatly enhances the human-computer interaction friendliness of the product.

[0014] Preferably, the adjustment mechanism is an adjustment screw, which is threadedly connected to the hollow threaded sleeve. One end of the spring abuts against the locating pin, and the other end abuts against the adjustment screw. Tightening the adjustment screw causes axial displacement within the hollow threaded sleeve, thereby changing the compression of the spring. This structure is simple and reliable, and users can easily achieve stepless adjustment of the tactile feel by simply rotating the adjustment screw.

[0015] Preferably, the adjustable tactile positioning component further includes a ball bearing; one end of the ball bearing protrudes from the end of the hollow threaded sleeve, and the other end abuts against the end of the positioning pin. This not only makes the adjustment mechanism's "adjustment feel" smoother but also improves the service life of the inner core.

[0016] Preferably, the adjustable tactile positioning component further includes a locking nut connected to the end of the hollow threaded sleeve; by operating the locking nut to adjust the hollow threaded sleeve, the hollow threaded sleeve can be made to abut against the outer wall of the inner core, so that the rotating component is in a completely locked state. This design allows the photographer to completely lock the rotating component after determining the shooting angle, providing absolute stability during long exposures or multiple photo shooting processes.

[0017] Preferably, a first planar bearing is provided between the rotating component and the top of the inner core. The introduction of the planar bearing makes the rotating component rotate smoothly, improving the operating feel and load-bearing capacity.

[0018] A further preferred embodiment connects the inner core and the rotating assembly using coaxially arranged connecting screws, with a second planar bearing positioned between the connecting screws and the inner core. This ensures the coaxiality of the inner core and the rotating assembly, improving both accuracy and the smoothness of adjustment.

[0019] Preferably, the indexing and positioning part consists of multiple indexing and positioning holes arranged along the outer periphery of the inner core.

[0020] Preferably, the clamping assembly includes a horizontal plate and a horizontal plate fixing member; the horizontal plate is limited by the dovetail groove and the horizontal plate fixing member, and the position of the horizontal plate is fixed by the horizontal plate fixing member.

[0021] More preferably, the horizontal plate is provided with an adjustable angle double-sided clamp, which can achieve a rotational adjustment of at least 90 degrees.

[0022] In a further preferred embodiment, the adjustable angle double-sided clamp is provided with an L-shaped quick-release plate.

[0023] Preferably, the bottom of the indexing table base is connected to an AKA-standard quick-release plate.

[0024] Preferably, the indexing table base is also provided with a brass wear-resistant threaded sleeve. This is used to connect other components, and the self-lubricating and wear-resistant properties of brass effectively prevent thread wear caused by frequent adjustments, thereby extending the service life of the entire turntable.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. Adjustable tactile feedback for a personalized experience: It is the first to adopt an adjustable tactile positioning component, breaking the limitation of the fixed tactile feedback of traditional indexing turntables. Users can freely adjust the feedback intensity of each gear, meeting personalized needs and improving the human-computer interaction experience and the reliability of operation confirmation.

[0026] 2. Robust and durable with a long service life: It adopts a thickened stainless steel hollow thread sleeve with a diameter of 7 mm, and innovatively embeds a brass wear-resistant thread sleeve on the indexing table base, which fundamentally solves the pain points of easy breakage of positioning screws and easy wear of threads in traditional products, and significantly enhances the durability and service life of the product.

[0027] 3. Precise positioning and absolute stability: The scientifically designed 18-level scale, combined with clear positioning feedback and a complete lock-up function, ensures precise positioning and absolute stability during shooting.

[0028] 4. Excellent overall performance: Through a series of optimized designs such as the 88mm large-diameter low center of gravity base, double-plane bearings, and extended and thickened cross plate, it achieves excellent load-bearing capacity and stability; at the same time, the abundant expansion holes and the well-designed quick-release plate accessories give it strong expandability and convenient operation.

These drawings are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0031] Figure 2 This is a cross-sectional schematic diagram of the present invention.

[0032] Figure 3 This is a schematic diagram of the adjustable tactile positioning component of this utility model. Detailed Implementation

[0033] The technical solution (including preferred technical solution) of this utility model will be further described in detail below with reference to the accompanying drawings and by listing some optional embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Example 1 Please see Figure 1 and Figure 2 This embodiment provides an adjustable tactile indexing turntable for multi-scene photography. The turntable mainly consists of an indexing table body, clamping components, and a series of functional accessories.

[0035] The indexing table body is the core component for achieving rotation and positioning. It includes an indexing table base 1 and a rotating assembly 2 that can rotate relative to the indexing table base 1. In this embodiment, the indexing table base 1 adopts a low center of gravity design with an outer diameter of 88 mm. This design provides a wide and stable support base for the entire system, effectively preventing tipping or swaying when supporting heavy photographic equipment. A 360-degree angle scale is laser-engraved on the outer peripheral wall of the indexing table base 1, with clear and precise graduations, facilitating accurate angle reference and readings for photographers.

[0036] The indexing table base 1 and the rotating assembly 2 are connected and fixed by a stainless steel inner core 8 and a connecting screw 10 at the bottom. To ensure extremely smooth rotation and stability under high load, two high-strength flat bearings are installed between them: a first flat bearing 7 between the rotating assembly 2 and the top of the inner core 8, and a second flat bearing 9 between the connecting screw 10 and the inner core 8. These two bearings jointly bear the axial pressure from the photographic equipment above, changing sliding friction into rolling friction, greatly reducing rotational damping, and making the rotational operation smooth and without jamming.

[0037] Multiple precision-machined indexing and positioning holes (not shown separately in the figure) are evenly distributed around the outer circumference of the inner core. These positioning holes are fitted with an adjustable tactile positioning component 14 mounted on the side wall of the rotating assembly 2. This adjustable tactile positioning component 14 is not a standard 6mm part commonly found on the market, but rather uses a custom-made, thickened stainless steel screw with a diameter of 7mm. The thicker wall provides it with higher bending and shear strength, making it less prone to breakage due to prolonged use or accidental stress.

[0038] The adjustable tactile positioning assembly 14 includes a hollow threaded sleeve 14.1, a positioning pin 14.2 that can move axially within the threaded sleeve 14.1, a spring 14.3 disposed within the threaded sleeve 14.1 and applying an elastic thrust to the positioning pin, and an adjustment mechanism 14.4 for adjusting the compression of the spring 14.3; the hollow threaded sleeve 14.1 is threadedly connected to the outer periphery of the rotating assembly 2; by operating the adjustment mechanism 14.4 to change the preset elastic thrust of the spring 14.3, the tactile intensity generated when the positioning pin 14.2 engages with the indexing positioning part can be adjusted.

[0039] In some specific embodiments of this utility model, the adjusting mechanism 14.4 is an adjusting screw, which is threadedly connected to the hollow threaded sleeve 14.1. One end of the spring 14.3 abuts against the locating pin 14.2, and the other end abuts against the adjusting screw. Tightening the adjusting screw causes axial displacement within the hollow threaded sleeve, thereby changing the compression of the spring 14.3. This structure is simple and reliable, and users can easily achieve stepless adjustment of the tactile feel by simply rotating the adjusting screw.

[0040] In some embodiments of this utility model, the adjustable tactile positioning component 14 further includes a ball bearing 14.5; one end of the ball bearing 14.5 protrudes from the end of the hollow threaded sleeve 14.1, and the other end abuts against the positioning pin end 14.2. This not only makes the adjustment mechanism's "adjustment feel" smoother, but also improves the service life of the inner core.

[0041] In this way, users can freely adjust the "click" sound and tactile feedback intensity when switching gears according to their own preferences, achieving stepless adjustment from strong and clear to soft and smooth.

[0042] Furthermore, the adjustable tactile positioning component 14 also includes a locking nut 14.6 connected to the end of the hollow threaded sleeve 14.1; by operating the locking nut to adjust the hollow threaded sleeve, the hollow threaded sleeve can be made to abut against the outer wall of the inner core, so that the rotating component is in a completely locked state. This design allows the photographer to completely lock the rotating component after determining the shooting angle, providing absolute stability during long exposures or multiple photo shooting processes.

[0043] In some embodiments of this utility model, the indexing table base 1 is further provided with a brass wear-resistant threaded sleeve 12. The brass wear-resistant threaded sleeve 12 is used to connect other components, and at the same time, by utilizing the self-lubricating and wear-resistant properties of brass, it effectively prevents thread wear caused by frequent adjustments, thereby extending the service life of the entire turntable.

[0044] The clamping assembly includes a horizontal plate 4 and a horizontal plate fixing member 6; the horizontal plate 4 is limited by the dovetail groove and the horizontal plate fixing member 6, and the position of the horizontal plate 4 is fixed by the horizontal plate fixing member 6.

[0045] For scenarios requiring extreme stability, a 200mm long, thickened crossbar 4 can be selected. This crossbar is 200mm long, 38mm wide, and 15mm thick, made of high-strength aluminum alloy, possessing extremely high rigidity, and can provide a stable, vibration-free support platform for large cameras and heavy telephoto lenses. The structure of the crossbar fixing component 6 is similar to that in CN106224716A.

[0046] The horizontal plate 4 is equipped with an adjustable angle double-sided clamp 3, which can achieve at least 90 degrees of rotational adjustment, providing photographers with flexible space for composition adjustment.

[0047] The bottom of the indexing table base 1 is equipped with a detachable Arca-standard quick-release plate 13, which is highly versatile and allows for quick installation and removal of cameras with Arca-standard quick-release plates.

[0048] In addition, this embodiment also provides a specially customized L-shaped quick-release plate 5 for vertical shooting, which is installed on the adjustable angle double-sided clamp 3. The L-shaped quick-release plate 5 is designed with full consideration of the interface layout of mainstream cameras. Its structure can perfectly avoid the shutter release cable socket, data interface and audio interface on the side of the camera, solving the problem that traditional L-plates may block the interfaces when shooting vertically, and ensuring the normal use of all functions.

[0049] During the process, the photographer first mounts the indexing turntable on a tripod, then secures the camera to the turntable using clamp 3 or L-shaped quick-release plate 5. When stitching panoramic images, the photographer can first adjust the adjustable tactile positioning screw 14 to a comfortable feel. After each shot, the photographer rotates the rotating component 2. When the ball bearing of the adjustable tactile positioning component 14 falls into the next indexing positioning hole, clear tactile and audible feedback is provided, indicating a precise rotation of 20 degrees (360 degrees / 18 stops). After shooting from all angles, a set of source photos for perfect stitching is obtained.

[0050] Those skilled in the art will readily understand that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, combinations, substitutions, improvements, etc., made under the spirit and principles of the present utility model are included within the protection scope of the present utility model.
