Description

Technical Field

[0001] This utility model relates to the field of shooting auxiliary equipment technology, and in particular to a shoulder strap holder. Background Technology

[0002] In daily life, to make it easier to carry photography equipment, we use strap clips to attach and secure the equipment to the straps of a backpack.

[0003] Current shoulder strap clips typically employ a rotary closure installation. For example, utility model publication number "CN214744841U" describes a quick-release device for backpack shoulder straps, comprising a quick-release base, a base plate, a first locking member, and a second locking member. The quick-release base includes opposing top and bottom ends along its thickness direction. The top end of the quick-release base has a device mounting portion for fixing a shooting device, and the quick-release base includes a first end and a second end spaced laterally. The outer end face of the first end is recessed laterally inward to form a mating cavity. The base plate is located near the bottom end of the quick-release base. The first locking member is rotatably connected to the base plate via a first rotating shaft extending along the width direction of the base plate. The first locking member can rotate to engage with the mating cavity to lock the first end to the base plate, or the first locking member can rotate to disengage from the mating cavity to release the first end from the base plate. The second locking member passes through the second end and the bottom plate, and is rotatably connected to the bottom plate via a second rotating shaft. The second rotating shaft extends along the width of the bottom plate, and the second locking member can lock or release the second end to the bottom plate. In this backpack quick-attachment device, the first locking member rotates outward about the first rotating shaft to disengage the first end of the quick-attachment base from the bottom plate. The quick-attachment base and the second locking member together rotate up and down about the second rotating shaft to open, allowing the backpack shoulder straps to be easily and quickly inserted between the quick-attachment base and the bottom plate. The first locking member is then rotated and engaged in the mating cavity of the quick-attachment base, and then the quick-attachment base and the bottom plate are locked together by the first and second locking members. This structure allows for quick and easy installation and fixation of the backpack shoulder straps, with no limitation on the opening angle, making operation more convenient.

[0004] However, the first and second locking components used to connect the quick-release base plate and the bottom plate in the above-mentioned backpack shoulder strap quick-release device have simple structures. Both the first and second locking components rotate around the horizontal axis, and there are no additional reinforcement components to achieve clamping, resulting in poor clamping effect and stability of the backpack shoulder strap. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shoulder strap clamp to solve the technical problem that the existing backpack shoulder strap quick-release devices have poor tightening effect and stability.

[0006] To achieve the above objectives, this utility model provides a shoulder strap holder, including a base plate, a base plate, an equipment mounting component, and fasteners. The base plate is disposed on the base plate, forming a shoulder strap holding channel between the base plate and the base plate. The equipment mounting component is detachably disposed on the side of the base plate opposite to the base plate. One end of the base plate is rotatably connected to the base plate, and the other end is snap-fitted to the base plate.

[0008] Optionally, the top end of the fastening post passes radially through the rotating shaft, and the knob is provided with a hanging ear. The hanging ear is hung on the end of the rotating shaft. The rotation of the knob drives the fastening post to rotate up and down within the base plate and the bottom plate. The up and down rotation of the fastening post adjusts the strap clamping channel.

[0009] Optionally, the other end of the base plate is provided with a snap-fit ​​structure, and the other end of the substrate is provided with a mating cavity. The mating cavity is recessed inward from the end of the substrate, and the snap-fit ​​structure is engaged in the mating cavity.

[0010] Optionally, the snap-fit ​​structure includes a snap-fit ​​block, which is vertically fixed to the other end of the base plate and snaps into the mating cavity.

[0017] The shoulder strap holder provided by this utility model has the following technical effects:

[0018] This shoulder strap holder includes a base plate, a bottom plate, a mounting component, and fasteners. Compared to existing technologies, traditional solutions rely solely on a rotating locking mechanism for clamping. This invention adds an adjustable fastening mechanism to the rotating buckle. In existing technologies, the locking component is directly fixed after rotation, making it impossible to adjust the pressure according to the strap thickness. This invention achieves precise control of the clamping force through threaded fasteners. In other words, through the above technical solution, this invention can adjust the clamping force according to the strap material and thickness, effectively preventing device wobbling. The dual locking mechanism of the rotating buckle and threaded fasteners significantly improves clamping stability, especially maintaining the device firmly fixed during movement.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] In existing technologies, photographic equipment is typically secured to backpack shoulder straps using strap clips. Traditional strap clips employ a rotary closure structure, such as a locking mechanism connected by a pivot, to achieve opening and closing. However, such structures lack robust design, resulting in insufficient clamping force. The equipment is prone to wobbling or even falling off during movement, affecting stability. When users need to move frequently while shooting outdoors, insufficient equipment stability can lead to decreased image quality or an increased risk of equipment damage.

[0035] To address the aforementioned issues, those skilled in the art discovered that existing locking mechanisms rely solely on shaft rotation for opening and closing, lacking auxiliary fastening structures and failing to adjust clamping force according to shoulder strap thickness. Multiple tests confirmed a direct correlation between insufficient clamping force and the simplistic locking method. Further analysis revealed that introducing an adjustable fastening mechanism into the locking mechanism, combined with the rotating snap-lock structure 5 to form a double-fixed system, effectively improves clamping stability. This discovery spurred the development of a gripper design with a composite locking structure.

[0036] Therefore, as Figure 1-6As shown, this utility model proposes a shoulder strap holder comprising a base plate 2, a base plate 1, an equipment mounting component 3, and a fastener 4. The base plate 2 is disposed on the base plate 1, forming a clamping channel between them for accommodating the shoulder strap. The equipment mounting component 3 is detachably mounted on the side of the base plate 2 opposite to the base plate 1. One end of the base plate 2 is connected to the base plate 1 via a rotating shaft, and the other end is fixed by a snap-fit ​​structure 5. The fastener 4 is disposed at the end of the base plate 2, extending through the base plate 2 to the base plate 1, and is used to adjust the clamping tightness of the clamping channel.

[0037] The base plate 2 is the main structure supporting the mounting component 3. It can be made of metal sheet or high-strength plastic injection molding, and its edge contour matches the base plate 1 to form a closed clamping space. The base plate 1 serves as the basic component supporting the base plate 2 and together with the base plate 2, forms a clamping channel for the shoulder strap to pass through. At the same time, the surface of the clamping channel can be provided with anti-slip texture to increase friction.

[0038] The equipment mounting component 3 is a connecting module used to fix the photographic equipment. Specifically, it can adopt a standard quick-release interface and connect to the base plate 2 via a snap-fit. The fastener 4 is an actuator for adjusting the clamping force. Specifically, it can adopt a threaded columnar structure, which generates axial displacement through rotational movement, thereby changing the distance between the base plate 2 and the base plate 1 and adjusting the clamping force.

[0039] Specifically, the base plate 2 is connected to one end of the base plate 1 via a rotating shaft to form a movable hinge, and the other end is equipped with a buckle structure 5 for quick opening and closing. When a shoulder strap needs to be installed, the buckle connection is released, the base plate 2 is rotated open, the shoulder strap is placed into the clamping channel, the base plate 2 is closed, and the buckle is fastened. The fastener 4 passes through the end of the base plate 2, and by twisting, the end of the fastener 4 presses against the base plate 1, thereby compressing the clamping channel space and making the base plate 2 and the base plate 1 form a stable clamp for the shoulder strap. The equipment mounting part 3 is located on the outside of the base plate 2, which facilitates quick installation and removal of the photography equipment without removing the shoulder strap.

[0040] Compared to existing technologies, traditional solutions rely solely on a rotating locking mechanism for clamping. This invention adds an adjustable fastening mechanism to the rotating buckle. In existing technologies, the locking mechanism is directly fixed after rotation, making it impossible to adjust the pressure according to the strap thickness. This invention achieves precise control of the clamping force through a threaded fastener 4. In other words, through the above technical solution, this invention can adjust the clamping force according to the strap material and thickness, effectively preventing equipment wobbling. The dual locking mechanism of the rotating buckle and threaded fastening significantly improves clamping stability, especially maintaining a firm grip on the equipment during movement. The detachable equipment mounting component 3 separates the strap clamping function from the equipment mounting function, avoiding the impact of repeated disassembly and reassembly of the clamp on the strap's fixation.

[0041] As a preferred embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the fastener 4 includes a fastening post 42 and a knob 41. The fastening post 42 passes vertically through the substrate 2 and is inserted into the base plate 1. The knob 41 is located at the top of the fastening post 42 and is rotatably connected to the fastening post 42.

[0042] The fastening post 42 in this embodiment is a vertical support component for connecting the substrate 2 and the base plate 1. Specifically, it can be implemented by using a threaded rod or a cylindrical structure with helical protrusions. The depth of its insertion into the base plate 1 can be adjusted by the knob 41 to change the clamping distance between the substrate 2 and the base plate 1.

[0043] The knob 41 is a rotating operating component connected to the top of the fastening post 42. Specifically, it can be implemented with a structure with anti-slip texture. When it rotates, it drives the fastening post 42 to generate axial displacement, thereby controlling the tightness of the strap clamping channel.

[0044] Specifically, the fastening post 42 penetrates the substrate 2 vertically and extends into the base plate 1, with its bottom end fixed to the base plate 1 via threads. The knob 41 is connected to the top of the fastening post 42 via a rotating shaft to change the clamping force between the substrate 2 and the base plate 1. The tightness of the strap clamping channel can be precisely adjusted by rotating the knob 41.

[0045] Detailed, such as Figure 1 As shown, the top of the fastening post 42 passes radially through the rotating shaft, and the knob 41 is provided with a hanging ear 411. The hanging ear 411 is hung on the end of the rotating shaft. The rotation of the knob 41 drives the fastening post 42 to rotate up and down in the base plate 2 and the bottom plate 1. The up and down rotation of the fastening post 42 adjusts the strap clamping channel.

[0046] The pivot is a cylindrical component that extends laterally through the top of the fastening post 42. It can be implemented using a metal rod or a rigid plastic shaft, and serves to provide a fulcrum for the rotation of the knob 41 and transmit torque. The lug 411 is a hook-shaped structure extending from the knob 41, and can be implemented using injection molding or stamping of a metal part. It connects the knob 41 to the pivot and limits the rotation range of the knob 41. The up-and-down rotation is the axial displacement movement of the fastening post 42 under threaded engagement. This can be achieved by providing threaded holes on the base plate 2 and the bottom plate 1, converting the rotation of the knob 41 into vertical movement of the fastening post 42 to adjust the gap of the clamping channel.

[0047] When using the knob 41, rotate it around the pivot until it is perpendicular to the substrate 2, and then hold the knob 41 to drive the fastening post 42 to rotate. When not in use, rotate it around the pivot until it is parallel to the substrate 2. This can prevent the knob 41 from accidentally hitting the body.

[0048] Specifically, as the knob 41 is rotated clockwise or counterclockwise, the fastening post 42 rises or falls vertically, thereby changing the distance between the base plate 2 and the bottom plate 1. This change in distance directly affects the strap clamping channel, enabling the channel width to be adjusted to accommodate straps of different thicknesses.

[0049] As a preferred embodiment, such as Figure 4 and Figure 5 As shown, the other end of the base plate 1 is provided with a snap-fit ​​structure 5, and the other end of the base plate 2 is provided with a mating cavity 21. The mating cavity 21 is recessed inward from the end of the base plate 2, and the snap-fit ​​structure 5 is snapped into the mating cavity 21.

[0050] The snap-fit ​​structure 5 is a component that achieves connection through mechanical engagement. Specifically, it can be implemented using a snap-fit ​​block 51 that is vertically fixed to the base plate 1. The nesting design of the snap-fit ​​block 51 and the mating cavity 21 can enhance the locking stability between the base plate 2 and the base plate 1. The mating cavity 21 is a spatial structure formed by the inward recess at the end of the base plate 2. It can be formed by stamping or injection molding. Its recess depth and shape match the snap-fit ​​block 51, and reliable fixation is achieved by constraining the displacement range of the snap-fit ​​block 51.

[0051] Specifically, such as Figure 5 As shown, the snap-fit ​​structure 5 includes a snap-fit ​​block 51, which is vertically fixed to the other end of the base plate 1 and snaps into the mating cavity 21.

[0052] The locking block 51 is a block-shaped structure that is vertically fixed to the end of the base plate 1. It can be implemented by welding, bolting or integral molding. It is used to form a rigid locking with the mating cavity 21 of the base plate 2 to enhance the connection stability.

[0053] Specifically, the locking block 51 is vertically fixed to the other end of the base plate 1. When the base plate 2 and the base plate 1 are closed, the locking block 51 is embedded in the mating cavity 21 of the base plate 2, and the relative displacement between the base plate 2 and the base plate 1 is restricted by the rigid contact between the two. For example, the locking block 51 can be designed as a cuboid structure, the width of which matches the spacing between the inner walls of the mating cavity 21 to ensure no gaps when locked in. Furthermore, the contact surface between the locking block 51 and the mating cavity 21 can be chamfered or have a guide bevel to facilitate self-alignment during the locking process. An elastic element 522 can be provided at the end of the base plate 1, for example, a spring can be installed at the bottom of the locking block 51 to generate a preload when the locking block 51 is locked in the mating cavity 21 to prevent loosening.

[0054] Compared with the prior art, which uses the first and second locking components to achieve single-point fixation only through the rotating shaft and does not have a nested buckle and cavity matching structure, this embodiment uses the nested design of the buckle 51 and the matching cavity 21 to make the locking force uniformly transmitted along the contact surface between the base plate 2 and the bottom plate 1.

[0055] See also Figure 5As shown, the other end of the base plate 1 is provided with a protrusion 52, the protrusion 52 is provided with an inwardly recessed cavity, the cavity is provided with a mounting post 521, the mounting post 521 is fitted with an elastic element 522, the locking block 51 is provided with a through hole 512, and the mounting post 521 and the elastic element 522 pass through the through hole 512.

[0056] Specifically, when the locking block 51 engages with the mounting post 521 and the elastic element 522 through the through hole 512, the elastic element 522 forms an axially compressed state between the locking block 51 and the mounting post 521. At this time, the locking block 51 is pressed against the inner wall of the cavity by the reaction force of the elastic element 522, forming a self-locking effect. Under external load, the elastic element 522 can absorb vibration energy through deformation.

[0057] To strengthen the connection between the card block 51 and the base plate 1, such as Figure 5 As shown, the locking block 51 has locking posts 511 on opposite sides, and the mating cavity 21 has several pairs of locking slots 22211 on both sides. When the locking block 51 is inserted into the mating cavity 21, the locking posts 511 are inserted one by one from the locking slots 22211 on one side into the locking slots 22211 on the other side.

[0058] The locking posts 511 are columnar protrusions located on both sides of the locking block 51, which can be implemented as cylinders or prisms, and are used to form multi-point contact with the locking grooves 22211. The locking grooves 22211 are grooves spaced apart on the side wall of the mating cavity 21, which can be implemented as arc-shaped groove structures. The horizontal part of the locking block 51 has locking posts 511 on both sides, and the vertical part has through holes 512, which can be implemented as T-shaped metal parts or plastic parts. The through holes 512 are used to pass through the mounting posts 521 and the elastic elements 522.

[0059] Specifically, during the insertion of the locking block 51 into the mating cavity 21, as the locking block 51 moves inward, the locking pins 511 on both sides of the horizontal portion of the locking block 51 sequentially engage with the locking slots 22211 at different positions. When the locking block 51 is fully inserted into the mating cavity 21, the locking pins 511 lock with the innermost locking slot 22211.

[0060] In this embodiment, the locking block 51 is preferably T-shaped, with locking posts 511 located on both sides of the horizontal portion of the locking block 51, and through holes 512 located on the vertical portion of the locking block 51. The T-shaped structure is a geometric shape formed by the horizontal and vertical portions, which can be achieved by integral molding. The horizontal portion provides symmetrical support on both sides, and the vertical portion is used to connect the elastic element 522 to enhance structural stability.

[0061] Specifically, the horizontal portion of the locking block 51 has locking posts 511 on both sides. When the locking block 51 is inserted into the mating cavity 21 of the base plate 2, the locking posts 511 are sequentially embedded into the locking slots 22211 on both sides. An elastic element 522 is installed in the through hole 512 of the vertical portion. When subjected to external pressure, the elastic element 522 is compressed, allowing the locking block 51 to finely adjust its position to adapt to the thickness of the strap. After the pressure is released, the elastic element 522 returns to its original position, maintaining a stable clamping force.

[0062] In addition, the above-described embodiments also include an arc-shaped cover 6, which is rotatably disposed at the other end of the substrate 2. The arc-shaped cover 6 covers the buckle structure 5, and the substrate 2 is also provided with a limiting post 61 to restrict the opening and closing of the arc-shaped cover 6.

[0063] The arc-shaped cover 6 is a covering component with an arc-shaped profile, which can be made of metal or plastic. Its curvature matches the shape of the snap-fit ​​structure 5. It is opened and closed by rotation, and is used to completely cover the snap-fit ​​structure 5 in the closed state to prevent the snap-fit ​​from loosening due to external force collision. The limiting post 61 is a columnar structure fixed on the base plate 2. Its position corresponds to the closed position of the arc-shaped cover 6. By restricting the opening and closing of the arc-shaped cover 6, it ensures that the arc-shaped cover 6 covers the snap-fit ​​structure 5.

[0064] Specifically, after the latching structure 5 locks the substrate 2 and the base plate 1, the arc-shaped cover 6 rotates around the pivot at the other end of the substrate 2 to cover the latching structure 5. At this time, the limiting post 61 is located at the end of the rotation path of the arc-shaped cover 6, which fixes the arc-shaped cover 6 by physical blocking, thereby maintaining the covering state of the arc-shaped cover 6 over the latching structure 5. The connection stability between the latching structure 5 and the substrate 2 is thus doubly guaranteed, on the one hand by the mechanical locking of the latch itself, and on the other hand by the wrapping protection of the arc-shaped cover 6.

[0065] In some specific embodiments, the pivot of the arc-shaped cover 6 can be set as a hinge structure, for example, the rotation function can be achieved by connecting with a pin; the limiting post 61 is set on the side of the base plate 2 near the buckle structure 5. When its height is slightly higher than the arc-shaped cover 6, the arc-shaped cover 6 covers the buckle structure 5. When pressed down, the arc-shaped cover 6 disengages.

[0066] As a more preferred implementation method, such as Figure 6 As shown, a recessed equipment mounting area is provided in the middle of the side surface of the substrate 2 opposite to the base plate 1, and the equipment mounting component 3 is detachably disposed in the equipment mounting area; a limiting protrusion 5231 for limiting and fixing the equipment mounting component 3 is provided in the equipment mounting area, and a push block 32 for controlling the sliding of the limiting protrusion 5231 is provided on one side of the substrate 2.

[0067] The equipment mounting area refers to a specific area formed by an inward recess in the middle of the surface of the substrate 2 and the base plate 1 on opposite sides. It can be achieved using stamping or injection molding processes and is used to accommodate and position the equipment mounting component 3, preventing it from shifting during clamping. The limiting protrusion 5231 is a raised structure located within the equipment mounting area. It can be made of elastic material or an adjustable mechanical component. The limiting protrusion 5231 engages with the equipment mounting component 3 through a locking mechanism. The sliding push block 32 is a movable component located on one side of the substrate 2. It can be implemented using a slider and groove structure. By pushing the sliding push block 32, the limiting protrusion 5231 moves up and down within the equipment mounting area, thereby adjusting the pressing or releasing state of the limiting protrusion 5231 on the equipment mounting component 3.

[0068] Specifically, when the equipment mounting component 3 needs to be fixed, the sliding push block 32 is pushed, and the equipment mounting component 3 is placed in the recessed space of the equipment mounting area, so that the limiting protrusion 5231 abuts against the bottom wall of the equipment mounting component 3. The limiting protrusion 5231 stabilizes the equipment mounting component 3 in the recessed area through its limiting action. When the equipment mounting component 3 needs to be removed, the sliding push block 32 is pushed in the opposite direction, and the limiting protrusion 5231 moves backward with the sliding push block 32, releasing the clamping force on the equipment mounting component 3. At this time, the equipment mounting component 3 can be directly removed or replaced.
