Description

Technical Field

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

[0002] In the field of photography, camera shoulder mounts are an important auxiliary device widely used to support and stabilize camera equipment. By mounting the camera equipment to a main support, the user can control the equipment by carrying it on their shoulder, thus providing stable support during shooting and improving the stability of the captured image.

[0003] However, existing camera shoulder supports are mostly fixedly connected to the main support, lacking an effective position adjustment mechanism. This makes it impossible to flexibly adjust the position of the shoulder support and the camera equipment it supports as needed. When loading large camera equipment, because the shoulder support position is fixed, the space occupied by the camera equipment remains unchanged. Since the photographer needs to frequently adjust his head posture during shooting, it is very easy for the camera equipment to directly rub against the head. This not only interrupts the continuity of shooting and causes operational obstacles, but may also cause the camera equipment to shake, affecting the stability of the image or even causing collisions and damage, interfering with the normal shooting state. Utility Model Content

[0004] The main purpose of this utility model is to propose a camera shoulder support, which aims to solve the technical problem that existing camera shoulder supports are fixed to the main support and lack an effective adjustment mechanism, which makes it easy for the camera equipment to rub against or get too close to the head, thus affecting the shooting.

[0005] To achieve the above objectives, this utility model proposes a photographic shoulder rest, comprising:

[0006] The main support has a first side and a second side arranged opposite to each other. The first side is provided with a device connection part for connecting a photography device, and the second side is provided with a first sliding structure that extends along the width direction of the main support.

[0007] The shoulder support is provided with a second sliding structure, which forms a sliding pair with the first sliding structure. The shoulder support can slide relative to the main support in the width direction.

[0008] A locking component is provided at the connection between the main support and the shoulder support. The locking component is configured to lock or unlock the relative positions of the first sliding structure and the second sliding structure to limit or allow the relative sliding of the shoulder support along the width direction of the main support.

[0009] In some embodiments, one of the first sliding structure and the second sliding structure is a slide groove provided along the width direction of the main support, and the other of the first sliding structure and the second sliding structure is a slider adapted to the slide groove, the slider being able to slide on the slide groove.

[0010] In some embodiments, the locking assembly includes a retainer that passes through at least one of the main support and the shoulder support, and the end of the retainer can abut against the slider to lock the slider in the groove, or release the slider to allow the slider to slide relative to the groove.

[0011] In some embodiments, the locking assembly further includes a control member connected to the abutment member, the control member being movable relative to the main support to move the abutment member.

[0012] In some embodiments, the control element is a knob, one end of which is connected to the abutment; the knob can be rotated under force to generate displacement along its own axis and push the abutment to move, so that the end of the abutment abuts against the slider or disengages from the slider;

[0013] Alternatively, the control element is a toggle element, which is hinged to the main bracket or the shoulder support via a screw. The abutment is threadedly connected to the screw. The toggle element can be rotated around the axis of the screw under force to drive the abutment to move along the axis of the screw. The abutment is connected to an elastic element.

[0014] In some embodiments, the first sliding structure includes a first sliding groove disposed along the width direction of the main support, and the second sliding structure includes a first slider connected to the shoulder support. The shoulder support is embedded in the first sliding groove through the first slider and can slide along the first sliding groove to achieve a sliding connection with the main support.

[0015] The abutment is inserted through the side wall of the main support, and the end of the abutment can be extended into the first groove to press against the first slider, or withdrawn from the first groove to release the first slider.

[0016] In some embodiments, the main support is provided with a receiving cavity communicating with the first slide groove, and the receiving cavity is located on one side of the first slide groove along the thickness direction of the main support;

[0017] The side wall of the main support is provided with a through hole communicating with the receiving cavity. The abutment is disposed in the receiving cavity and can move in the receiving cavity along the axial direction of the through hole. The control member passes through the through hole and is connected to the abutment. The control member can drive the abutment to move along the axial direction of the through hole so that the end of the abutment extends out of the receiving cavity and extends into the first sliding groove to press against the first slider, or retracts into the receiving cavity to release the first slider.

[0018] In some embodiments, the end of the abutment is formed with a wedge-shaped surface, and the side of the first slider is provided with an inclined mating surface adapted to the wedge-shaped surface. The wedge-shaped surface can fit and abut against the inclined mating surface to lock the first slider in the first groove; or, the wedge-shaped surface is separated from the inclined mating surface so that the first slider can slide relative to the first groove.

[0019] In some embodiments, the first slider is provided with a limiting groove arranged along its sliding direction, and the inner walls of the limiting groove on both sides in the sliding direction form limiting end faces. The main bracket is provided with a limiting post, one end of which is located in the limiting groove, and the outer peripheral wall of the limiting post can abut against the limiting end face to limit the sliding stroke of the first slider relative to the first sliding groove.

[0020] In some embodiments, the first sliding structure further includes a second sliding groove disposed along the width direction of the main support, the second sliding groove being disposed parallel to and spaced apart from the first sliding groove, and the second sliding structure further includes a second slider connected to the shoulder support, the second slider being embedded in the second sliding groove and being able to slide along the second sliding groove.

[0021] In some embodiments, the camera shoulder support further includes a back support connected to the shoulder support, and the back support is positionally adjustable relative to the main support along the width direction.

[0022] The camera shoulder support provided by this utility model achieves a sliding connection between the shoulder support and the main support by setting a first sliding structure extending along the width direction on the second side of the main support, forming a sliding pair with a second sliding structure on the shoulder support. The relative position of the first and second sliding structures is locked or unlocked by a locking component located at the connection point, thereby realizing the position adjustment function of the shoulder support in the width direction. Users can flexibly adjust the space occupied by the camera according to the size of the camera, effectively preventing the camera from rubbing against the head during shooting, ensuring the continuity of shooting and the safety of the equipment, and improving the overall operational stability and applicability.

[0037] Please refer to Figures 1 to 3 This application provides a photographic shoulder support 100, which includes a main support 10, a shoulder support 20, and a locking assembly 30.

[0038] The main support 10 has a first side 11 and a second side 12 arranged opposite to each other. The first side 11 is provided with a device connection part 111 for connecting a photographic device, and the second side 12 is provided with a first sliding structure 121, which extends along the width direction of the main support 10.

[0039] The shoulder support 20 is provided with a second sliding structure 21, which forms a sliding pair with the first sliding structure 121, and the shoulder support 20 can slide relative to the main support 10 in the width direction.

[0040] The locking component 30 is located at the connection between the main support 10 and the shoulder support 20. The locking component 30 is configured to lock or unlock the relative positions of the first sliding structure 121 and the second sliding structure 21 to restrict or allow the shoulder support 20 to slide relative to each other along the width direction of the main support 10.

[0041] The main support 10, as the core load-bearing and connecting component of the camera shoulder support 100, has a first side 11 and a second side 12 arranged opposite to each other, forming the main frame supporting the equipment. The first side 11 is equipped with an equipment connection part 111 for securely connecting camera equipment such as camcorders and SLR cameras. Standardized interfaces such as bolts, quick-release plates, and clips allow for quick loading, unloading, and positioning of the equipment, ensuring a rigid connection between the camera equipment and the main support 10 during shooting and guaranteeing image stability. The second side 12 integrates a first sliding structure 121, which extends along the width of the main support 10. This structure serves as a guide for the sliding adjustment of the shoulder support 20, providing precise motion trajectory constraints for the position adjustment of the shoulder support 20 and ensuring the smoothness and straightness of the sliding process.

[0042] The shoulder rest 20 is a support component that contacts the photographer's shoulder. Its surface typically features an ergonomically designed curved shape to distribute the weight of the equipment and improve shoulder comfort. The shoulder rest 20 has a second sliding structure 21 that is adapted to the first sliding structure 121 of the main support 10. The two form a sliding pair (such as a slide rail and slider, a slide groove and a convex rail, etc.). Through this sliding pair, the shoulder rest 20 and the main support 10 form a sliding connection along the width direction, allowing the shoulder rest 20 to be translated and adjusted along the width direction of the main support 10 (i.e., the horizontal direction parallel to the photographer's shoulder). This enables flexible adjustment of the spatial position of the shoulder rest 20, thereby adapting to the operational needs of photographers of different body types and the spatial requirements of shooting scenes.

[0043] The locking assembly 30 is located at the connection between the main support 10 and the shoulder rest 20, and is the core functional component for achieving position locking. It is configured to fix or release the relative position of the first sliding structure 121 and the second sliding structure 21 through mechanical locking methods (such as threaded locking, eccentric wheel clamping, snap-lock positioning, etc.). When the position of the shoulder rest 20 needs to be adjusted, unlocking the locking assembly 30 releases the sliding constraint, allowing the shoulder rest 20 to slide freely. After adjustment to the target position, the locking assembly 30 rigidly fixes the sliding pair by applying clamping force or a locking mechanism, ensuring that the shoulder rest 20 and the photographic equipment remain stable during shooting, preventing positional shifts caused by vibration or external forces from affecting image quality.

[0044] This embodiment of the application, through the cooperative design of the first sliding structure 121 and the second sliding structure 21, overcomes the technical limitations of the existing fixed connection between the shoulder support 20 and the main support 10, allowing the spatial position of the shoulder support 20 and the photographic equipment it supports to be adjusted as needed along the width direction of the main support 10. Photographers can flexibly adjust the position of the shoulder support 20 according to their body type (shoulder width, height), shooting posture (standing, low-angle shooting), or equipment specifications, ensuring comfortable operating posture, reducing muscle fatigue during long-term shooting, and improving the adaptability of equipment use.

[0045] When mounting large photographic equipment, photographers can adjust the shoulder rest position 20 to change the space occupied by the equipment, increasing the safe distance between the equipment and the head. This effectively prevents direct contact between the equipment and the head when adjusting head posture during shooting (such as looking through the viewfinder or tilting the head to frame the shot), ensuring continuity of the shooting process, reducing operational obstacles, and preventing equipment shaking or damage caused by collisions. This ensures image stability and equipment safety, thereby improving overall operational stability and applicability.

[0046] In some embodiments, one of the first sliding structure 121 and the second sliding structure 21 is a slide groove provided along the width direction of the main support 10, and the other of the first sliding structure 121 and the second sliding structure 21 is a slider adapted to the slide groove, and the slider can slide on the slide groove.

[0047] In this design, the sliding groove, serving as a guide for the sliding fit, defines the sliding trajectory and adjustment range of the slider through its preset groove length and extension direction, ensuring that the shoulder support 20 moves directionally along the width of the main support 10. This groove structure provides a protective enclosure for the slider, preventing external dust and impurities from directly intruding into the sliding mating surface, reducing wear risk, and extending the structural service life.

[0048] The slider, serving as an intermediate component connecting the shoulder support 20 and the slide groove, has one end rigidly connected to the shoulder support 20 and the other end embedded inside the slide groove. It transmits the force from the shoulder support 20 to the main support 10, achieving uniform force distribution. The tight fit between the slider and the slide groove eliminates gap errors, ensuring the positional accuracy of the shoulder support 20 during sliding and preventing equipment wobbling due to structural looseness. Furthermore, the end shape of the slider can be designed as arc-shaped or stepped, further optimizing the fit with the slide groove and improving sliding stability and smooth adjustment.

[0049] In this embodiment, the rigid fit between the groove and the slider effectively restricts the degree of freedom in the sliding direction, avoiding phenomena such as swaying or jamming during adjustment, and ensuring that the shoulder support 20 moves smoothly along the preset trajectory. Compared with other sliding forms, this structure has smaller gaps and higher position adjustment precision. Photographers can achieve precise positioning of the shoulder support 20 through fine operations, meeting the precise adaptation needs of different shooting scenarios.

[0050] For example, the slider can be designed as a dovetail block with a trapezoidal cross section, with its two inclined sides fixedly connected to the bottom of the shoulder support 20; the corresponding groove is set as a dovetail groove extending along the width direction of the main support 10, with the groove opening width being smaller than the groove bottom width, and the inner walls on both sides being inclined and closely fitting the inclined sides of the dovetail block. This complementary trapezoidal structure achieves anti-fall constraint and precise guidance during sliding.

[0051] In some embodiments, the locking assembly 30 includes a retainer 31, which passes through at least one of the main support 10 and the shoulder support 20, and the end of the retainer 31 can abut against the slider to lock the slider in the groove, or release the slider so that the slider can slide relative to the groove.

[0052] In the locked state, the end of the abutment 31 applies axial pressure to tightly adhere to the surface of the slider, forming sufficient static friction to resist the slider's tendency to slide due to the weight of the equipment or external impact. Its pressure distribution is uniform, which can avoid excessive local stress that could cause deformation of the slider or groove. At the same time, the rigid abutment ensures that there is no relative displacement between the slider and the groove, ensuring the positional stability of the shoulder support 20 and the photographic equipment during shooting and preventing accidental sliding caused by vibration or bumps.

[0053] In the unlocked state, the end of the retaining member 31 maintains a gap or only slight contact with the slider surface, eliminating resistance interference to the slider's sliding. The structural design of the retaining member 31 makes its operating stroke controllable, allowing the photographer to judge the degree of unlocking by feel, ensuring that the locking constraint is completely released while avoiding the risk of the retaining member 31 falling off due to excessive loosening.

[0054] In this embodiment, the operation of the abutment 31 is simple and intuitive, requiring no complex tools to switch between locking and unlocking. The photographer can operate it with one hand for quick adjustment, reducing operation interruption time during shooting and improving responsiveness in dynamic scenes. At the same time, the locking force can be flexibly controlled through the range of operation to adapt to the locking needs of devices of different weights.

[0055] In some embodiments, the locking assembly 30 further includes a control member 32 connected to the abutment member 31, and the control member 32 is movable relative to the main support 10 to drive the abutment member 31 to move.

[0056] Among them, the control component 32 reduces the force required for operation through optimized structural design (such as knobs with extended lever arms and force-saving lever structures), efficiently transferring the photographer's hand operation force to the support component 31. For scenarios requiring greater locking force, the control component 32 can amplify the force through a threaded helix design, allowing the photographer to obtain sufficient locking pressure without applying excessive force, reducing operational intensity, and is especially suitable for shooting scenarios with frequent adjustments over long periods of time.

[0057] Furthermore, the travel distance of the control component 32 precisely matches the locking travel distance of the holding component 31. Its surface is typically marked with scales or limit structures, allowing the photographer to visually determine the locking status of the holding component 31 by observing the position of the control component 32. For example, a knob-type control component 32 can control the feed amount of the holding component 31 by the number of rotations, while a lever-type control component 32 can display the degree of locking by the distance it is pushed or pulled, ensuring the controllability and consistency of the operation process.

[0058] In this embodiment, the movement of the supporting member 31 can be precisely controlled through the structured transmission of the control member 32, avoiding problems such as uneven force and stroke deviation caused by direct operation of the supporting member 31. During multiple adjustments of the same locking component 30, the standardized movement of the control member 32 ensures the consistency of the locking force and position of the supporting member 31, improving the reliability and stability of the equipment.

[0059] In some embodiments, the operating end of the control element 32 adopts an ergonomic design, such as non-slip rubber material, curved grip surface or wavy texture, to improve the stability and comfort of hand grip.

[0060] Please refer to Figure 5In some embodiments, the control element 32 is a knob, one end of which is connected to the abutment 31; the knob can be rotated under force to generate displacement along its own axis and push the abutment 31 to move, so that the end of the abutment 31 abuts against the slider or disengages from the slider.

[0061] When the knob is used as the control element 32, it can form a threaded engagement with the main bracket 10 or the shoulder support 20. By rotating, it generates axial displacement. On the one hand, it receives external operating force and converts it into a driving force to move the abutment 31. On the other hand, it maintains a fixed position in the locked state through the self-locking characteristic of the thread, preventing the abutment 31 from loosening accidentally.

[0062] In this embodiment, the knob control allows for locking and unlocking simply by rotating it, with controllable operating stroke, making it suitable for scenarios requiring precise adjustment of the shoulder rest position. Furthermore, the knob's engagement with the threaded joint provides excellent self-locking performance and strong vibration resistance when locked, making it suitable for complex environments such as outdoor shooting.

[0063] Please refer to Figure 6 and Figure 7 In some embodiments, the control member 32 is a toggle member, which is hinged to the main support 10 or shoulder support 20 via a screw 33. The abutment member 31 is threadedly connected to the screw 33. The toggle member can be rotated around the axis of the screw 33 under force to drive the abutment member 31 to move along the axis of the screw 33. The abutment member 31 is connected to an elastic member 34.

[0064] When the actuating component is used as the control component 32, it serves as the operation input end to receive external control force. It transmits the force to the screw 33 through rotational motion around the screw 33, thereby driving the supporting component 31 to move. Its structural design conforms to ergonomics, making it easy for users to quickly apply or remove external force, thus achieving convenient control over the locking state.

[0065] The screw 33 serves the dual functions of a hinge shaft and a transmission component. As a hinge shaft, the screw 33 provides rotational support for the actuating component, limiting the relative translational movement of the actuating component and the main support 10 or shoulder support 20. As a transmission component, the screw 33 converts its own rotational motion into the axial displacement of the abutment 31 through threaded engagement with the abutment 31, thus realizing the transmission of force and motion.

[0066] The elastic element 34 is connected to the abutment 31. When the abutment 31 moves away from the slider as the screw 33 rotates, the elastic element 34 is compressed or stretched to store elastic potential energy. Since the threaded connection has self-locking properties, the abutment 31 will not move in the opposite direction due to its own weight or vibration after the external force is removed. The release of potential energy of the elastic element 34 will apply a continuous preload to the abutment 31, ensuring that the abutment 31 always tightly abuts the slider when it is in the locked position, avoiding loosening caused by thread clearance.

[0067] In this embodiment, the toggle-type control utilizes the lever effect of the toggle and the threaded transmission of the screw 33. The user only needs to apply a small external force to complete the unlocking operation, and the self-locking characteristic of the thread eliminates the need for an additional fixing structure. Combined with the pre-tightening of the elastic element 34, it balances ease of operation and positional stability. Since the screw 33 integrates hinge and transmission functions, the number of independent components is reduced. At the same time, the components are connected by threads, hinges, etc., resulting in a simple layout and helping to reduce the overall structural volume.

[0068] It should be understood that the two control methods can meet the operating habits of different users. The knob type is suitable for users who prefer fine adjustment, while the toggle type is suitable for users who pursue fast operation. Both structures adopt a modular design, which is convenient for assembly and replacement according to actual needs, thereby improving the versatility and expandability of the product.

[0069] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the first sliding structure 121 includes a first sliding groove 1211 provided along the width direction of the main support 10, and the second sliding structure 21 includes a first slider 211 connected to the shoulder support 20. The shoulder support 20 is embedded in the first sliding groove 1211 through the first slider 211 and can slide along the first sliding groove 1211 to achieve a sliding connection with the main support 10.

[0070] The abutment 31 is inserted through the side wall of the main support 10, and the end of the abutment 31 can be inserted into the first slide groove 1211 to press against the first slider 211, or withdraw from the first slide groove 1211 to release the first slider 211.

[0071] In this embodiment, the first slide groove 1211 is formed on the side wall of the main support 10 along the width direction of the main support 10, providing a guide channel for the linear sliding of the first slider 211, ensuring that the slider moves in a preset direction and reduces sway. At the same time, the depth and width of the groove are designed to accommodate the first slider 211 and reserve an adjustment gap, balancing the smoothness of sliding and the positional accuracy. The first slider 211 is rigidly connected to the shoulder support 20, and its shape is precisely adapted to the inner cavity of the first slide groove 1211, allowing it to slide freely along the length direction of the groove to adjust the position of the shoulder support 20.

[0072] The arrangement of the abutment 31, which passes through the side wall of the main support 10, ensures that its operating point directly corresponds to its point of action. The depth of its end extending into the groove allows for precise control of the locking force: the greater the depth, the greater the normal pressure between the abutment 31 and the slider, the stronger the static friction, and the more stable the locking; conversely, the less depth, the more thorough the unlocking. Its end is typically designed as an arc or a flat structure. The arc end can adapt to the contact requirements of different positions of the slider, while the flat end can increase the contact area, improve locking reliability, and avoid local stress concentration that could damage the slider.

[0073] Since the abutment 31 extends directly from the side wall of the main bracket 10 into the first slide groove 1211 and acts on the side of the slider, the force transmission path is short, which can efficiently convert the operating force into locking friction force and reduce force loss. Moreover, the rigid fit between the first slide groove 1211 and the first slider 211 restricts the first slider 211's other degrees of freedom except for the sliding direction. Combined with the directional pressure of the abutment from the side wall of the main bracket 10, it can effectively prevent the first slider 211 from moving under complex shooting conditions and improve the accuracy of position locking.

[0074] Please continue to refer to this. Figure 4 In some embodiments, the main support 10 is provided with a receiving cavity 13 communicating with the first slide groove 1211, and the receiving cavity 13 is located on one side of the first slide groove 1211 along the thickness direction of the main support 10.

[0075] The side wall of the main support 10 is provided with a through hole 14 communicating with the receiving cavity 13. The abutment 31 is provided in the receiving cavity 13 and can move in the receiving cavity 13 along the axial direction of the through hole 14. The control member 32 passes through the through hole 14 and is connected to the abutment 31. The control member 32 can drive the abutment 31 to move along the axial direction of the through hole 14 so that the end of the abutment 31 extends out of the receiving cavity 13 and extends into the first slide groove 1211 to press against the first slider 211, or retracts into the receiving cavity 13 to release the first slider 211.

[0076] The receiving cavity 13 serves as the movement track and protective space for the abutment 31. The clearance fit between its inner wall and the abutment 31 provides axial guidance for the abutment 31, restricts the radial sway of the abutment 31, and ensures that the end is accurately aligned with the opening of the first slide groove 1211.

[0077] The depth and inner diameter of the receiving cavity 13 are adapted to the length and diameter of the supporting member 31, which not only provides sufficient extension and retraction stroke for the supporting member 31, but also protects the supporting member 31 from external collisions by enclosing it in the cavity, while preventing dust and impurities from entering the moving mating surface, ensuring smooth long-term movement.

[0078] The through hole 14 serves as a connecting channel between the control member 32 and the supporting member 31. Its axis is collinear with the axis of the receiving cavity 13, providing stable guiding support for the control member 32 and ensuring that there is no deviation when the control member 32 drives the supporting member 31 to move. After passing through the through hole 14, the control member 32 is rigidly connected to the supporting member 31, transmitting external operating force to the supporting member 31 without loss, thus achieving precise force transmission.

[0079] The movement of the abutment 31 within the receiving cavity 13 is limited by both the depth of the receiving cavity 13 and the length of the through hole 14. Its maximum extension is limited to just pressing against the first slider 211 to avoid excessive extension that could compress the groove or slider and cause structural deformation. The minimum retraction ensures that the end is completely disengaged from the first groove 1211 and does not fall out of the receiving cavity 13, preventing the abutment 31 from falling off.

[0080] In this embodiment, the full-stroke guide of the receiving cavity 13 to the abutment 31 eliminates radial movement, ensuring that the end of the abutment 31 is always precisely aligned with the first slide groove 1211. This avoids locking failure or jamming caused by offset, ensures consistent contact position and pressure during each locking, and significantly reduces the risk of locking loosening due to positioning deviation. It is especially suitable for the stable support requirements of high-precision shooting equipment.

[0081] Please continue to refer to this. Figure 5 In some embodiments, the end of the abutment 31 is formed with a wedge-shaped surface 311, and the side of the first slider 211 is provided with an inclined mating surface 2111 adapted to the wedge-shaped surface 311. The wedge-shaped surface 311 can fit and abut against the inclined mating surface 2111 to lock the first slider 211 in the first slide groove 1211; or, the wedge-shaped surface 311 is separated from the inclined mating surface 2111 so that the first slider 211 can slide relative to the first slide groove 1211.

[0082] In this embodiment, the wedge-shaped surface 311 at the end of the abutment 31 and the inclined mating surface 2111 on the side of the first slider 211 are designed with complementary inclined angles to form a precisely fitting inclined mating structure. When the abutment 31 moves axially toward the first slide groove 1211, the wedge-shaped surface 311 gradually approaches and fits the inclined mating surface 2111. Utilizing the force component effect generated by the inclined contact, the axial pressure of the abutment 31 is converted into a lateral clamping force perpendicular to the sliding direction, causing the first slider 211 to fit tightly against the inner wall of the first slide groove 1211. The rigid locking of the first slider 211 is achieved through the dual action of friction and lateral constraint. When the abutment 31 moves in the opposite direction, the wedge-shaped surface 311 separates from the inclined mating surface 2111, the lateral clamping force disappears, and the constraint between the first slider 211 and the inner wall of the first slide groove 1211 is released, allowing it to slide freely along the first slide groove 1211, thus completing the switching between the locked and unlocked states.

[0083] This structure utilizes the principle of force-saving through inclined surfaces. The engagement between the wedge-shaped surface 311 and the inclined mating surface 2111 amplifies the axial operating force of the supporting member 31 into a larger lateral locking force. This allows for stable locking of the slider with relatively little operating force applied by the photographer, reducing operational intensity. Compared to planar contact locking, the inclined surface engagement provides multi-directional constraints, not only limiting the axial sliding of the slider but also suppressing radial movement of the slider within the groove, significantly improving structural stability in the locked state.

[0084] Please continue to refer to this. Figure 4 and Figure 5In some embodiments, the first slider 211 is provided with a limiting groove 2112 arranged along its sliding direction. The inner walls of the limiting groove 2112 on both sides in the sliding direction form limiting end faces 2113. The main support 10 is provided with a limiting post 15. One end of the limiting post 15 is located in the limiting groove 2112, and the outer peripheral wall of the limiting post 15 can abut against the limiting end face 2113 to limit the sliding stroke of the first slider 211 relative to the first sliding groove 1211.

[0085] The limiting groove 2112 limits the maximum sliding range of the first slider 211 through the limiting end faces 2113 on both sides. Its groove length is precisely designed according to the actual adjustment requirements to ensure that the effective adjustment stroke of the first slider 211 meets the position adaptation requirements of the shoulder support 20, while reserving a safety margin to prevent excessive sliding.

[0086] The limiting post 15 serves as a fixed fulcrum, and its outer peripheral wall achieves rigid limiting through contact with the limiting end face 2113. It resists the impact force generated by the sliding of the first slider 211 through its own structural strength, distributing the limiting force throughout the main support 10 and avoiding localized stress concentration. The length of the limiting post 15 extending into the limiting groove 2112 ensures that it remains within the limiting groove 2112 throughout the entire stroke of the first slider 211, preventing it from disengaging from the limiting groove 2112 and causing limiting failure. Its end can be designed with rounded corners to reduce contact wear when abutting against the limiting end face 2113, extending the component's service life.

[0087] When the first slider 211 slides along the first groove 1211, the limiting groove 2112 moves synchronously with the first slider 211. When the first slider 211 slides to a position close to the end of its stroke, the limiting end face 2113 on one side of the limiting groove 2112 gradually approaches the outer peripheral wall of the limiting post 15. When the first slider 211 reaches its maximum sliding stroke, the limiting end face 2113 abuts tightly against the outer peripheral wall of the limiting post 15, blocking the first slider 211 from continuing to move through rigid contact, thereby limiting the sliding range of the first slider 211. When sliding in the opposite direction, the abutment between the limiting end face 2113 on the other side and the limiting post 15 limits the excessive sliding of the first slider 211 in the opposite direction, forming a bidirectional stroke constraint mechanism.

[0088] This embodiment uses rigid limiting to prevent the first slider 211 from sliding excessively, effectively preventing it from detaching from the end of the first groove 1211 or colliding with other components. This avoids problems such as groove deformation and slider damage caused by overtravel operation, protecting the integrity of the sliding fit structure. During limiting contact, the large-area contact between the limiting post 15 and the limiting end face 2113 disperses the impact force, reducing local wear. Combined with a rounded corner transition design, this further reduces stress concentration and significantly improves the long-term durability of the structure.

[0089] Please refer to Figure 4 and Figure 5In some embodiments, the first sliding structure 121 further includes a second sliding groove 1212 disposed along the width direction of the main support 10. The second sliding groove 1212 is disposed parallel to and spaced apart from the first sliding groove 1211. The second sliding structure 21 also includes a second slider 212 connected to the shoulder support 20. The second slider 212 is embedded in the second sliding groove 1212 and can slide along the second sliding groove 1212.

[0090] The second slide rail 1212 serves as an auxiliary guide rail, forming a symmetrical force-bearing support system together with the first slide rail 1211. Its extension direction is parallel to the first slide rail 1211, and the spacing design balances the force distribution on the shoulder support 20. The second slider 212 and the first slider 211 are symmetrically distributed at the bottom of the shoulder support 20, jointly bearing the weight of the shoulder support 20 and the photographic equipment, evenly distributing the load across the two slide rails and reducing the force load on a single sliding structure. The length of the second slider 212 is adapted to the second slide rail 1212, ensuring sufficient length to be embedded in the second slide rail 1212 throughout the sliding stroke, providing continuous and stable support.

[0091] In this embodiment, the first sliding structure 121, by adding a second sliding groove 1212 parallel and spaced from the first sliding groove 1211, forms a double-track sliding engagement system with the corresponding second slider 212 in the second sliding structure 21. This two-point positioning eliminates the rotational degree of freedom of the shoulder support 20. Compared to a single sliding groove structure, this effectively suppresses instability phenomena such as swaying and torsion of the shoulder support 20 during sliding, ensuring that the shoulder support 20 always translates along a preset direction. The two sets of sliding structures share the weight and operating force of the equipment, reducing the force on each slider groove by half, significantly reducing the wear rate of individual components, and extending the service life of the overall structure. This is particularly suitable for scenarios involving the loading of heavy photographic equipment.

[0092] Furthermore, the parallel, spaced dual-track design makes the force distribution of the shoulder support 20 more even, avoiding the problem of localized stress concentration caused by the center of gravity shift when using a single track. The second slide groove 1212 and the second slider 212 can provide precise support for the end of the shoulder support 20 away from the first slide groove 1211, balancing the torque generated by the weight of the equipment, preventing the end of the shoulder support 20 from sagging and deforming, ensuring that the photographic equipment always maintains a horizontal posture, and improving the stability of the captured image. The dual-support structure has a higher load-bearing limit and can be adapted to larger and heavier photographic equipment combinations, expanding the applicability of the photographic shoulder support 100.

[0093] Please continue to refer to this. Figure 1 In some embodiments, the camera shoulder support 100 also includes a back support 40, which is connected to the shoulder support 20, and the back support 40 can be adjusted in position relative to the main support 10 in the width direction along with the shoulder support 20.

[0094] The back support 40 contacts the photographer's back and features an ergonomically designed curved surface that conforms closely to the back's contours. This distributes some of the weight of the shoulder support 20 and the equipment to the back, further reducing shoulder pressure and alleviating muscle fatigue during long shooting sessions. The back support 40 is typically made of high-density sponge or silicone composite material, combining elastic cushioning with supportive rigidity. It can adapt to different back curves through deformation while providing stable support and reaction force, preventing equipment swaying from affecting shooting stability.

[0095] In this embodiment, the back support 40 is connected to the shoulder support 20 via a rigid connection or an adjustable connector, and its spatial position changes synchronously with the sliding adjustment of the shoulder support 20. When the shoulder support 20 slides along the first slide groove 1211 and the second slide groove 1212 of the main bracket 10 via the first slider 211 and the second slider 212, the back support 40, through its fixed connection with the shoulder support 20, moves along the width direction of the main bracket 10 together with the shoulder support 20, realizing synchronous position adjustment of the back support 40, the shoulder support 20, and the photographic equipment. This linkage mechanism ensures that the support position of the back support 40 is always adapted to the spatial layout of the shoulder support 20 and the equipment, meeting the support needs of photographers of different body types.

Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
