Description

Technical Field

[0001] This utility model belongs to the field of adjustment buckle technology, and specifically relates to an adjustment buckle. Background Technology

[0002] Adjustable buckles, also known as shoulder strap buckles, are used for adjusting shoulder straps on bags and cameras. They allow for strap length adjustment to accommodate different heights and body types, and offer multi-functionality, such as detachable straps. They also secure the strap, preventing slippage. Furthermore, they enhance the product's aesthetics. Current shoulder strap buckles use hooks that engage with rings on cameras or bags; however, hooks can easily damage the leather and surface. Conventional buckles require both hooks and adjustable buckles for strap adjustment, resulting in numerous and complex hardware components. Using hooks causes the strap to rotate, requiring adjustments to prevent tangling. Removing the hook leaves the matching ring on the bag, which is unsightly and adds weight. To address at least one of these technical issues, it is necessary to develop an adjustable buckle. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable buckle to solve the above-mentioned technical problems. By limiting or releasing the mutual limiting of the limiting unit and the abutment element, the connection between the buckle body and the object is controlled. This connection method is simple. After the buckle body and the abutment element are connected, the abutment element extends into the inside of the buckle body and moves synchronously with the object. This prevents the abutment element connected to the object and the buckle body from shaking like in the prior art, which would cause wear on the surface of the object. The overall size of the connection structure is small, and fewer components are required. The abutment element is connected to the object and does not shake relative to the object. This avoids the situation where the abutment element moves relative to the buckle body after being connected to the limiting unit, thereby avoiding the problem of shoulder strap rotation.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable buckle includes a buckle body connectable to a shoulder strap and a limiting unit disposed on the buckle body and cooperating with an abutment element to control the mutual limiting or release of the limiting between the two. The buckle body has a first cavity, wherein the abutment element is fixedly disposed on an object to be connected, such as a camera or bag. The buckle body connected to the shoulder strap has a limiting unit. The connection between the buckle body and the object is controlled by the mutual limiting or release of the limiting unit and the abutment element. This connection method is simple. After the buckle body and the abutment element are connected, the abutment element extends into the buckle body and moves synchronously with the object. This prevents the abutment element connected to the object and the buckle body from wobbling like in existing hooks, which could cause wear on the object's surface. The overall size of the connection structure is small, requiring fewer components. The abutment element is connected to the object and does not wobble relative to it, avoiding relative movement between the abutment element and the buckle body after connection with the limiting unit, thus preventing shoulder strap rotation.

[0006] Preferably, the limiting unit includes limiting holes of different sizes for controlling the limiting or releasing of the abutment element. The limiting holes are connected to the first cavity. By setting different sizes for the limiting holes, the connection state between the limiting holes and the abutment element is controlled to be mutually limiting or releasing, thereby controlling the connection state between the buckle body and the abutment element. The limiting holes correspond to the axial direction of the abutment element, thereby controlling whether the abutment element and the limiting holes can be disengaged in the axial direction or mutually limited. This connection method is simple, and after connection, the abutment element extends into the buckle body, resulting in a smaller overall volume. Furthermore, there is no relative movement between the buckle body and the abutment element, thus avoiding wear on the object surface.

[0007] Preferably, the limiting hole includes a first through hole and a second through hole that are disposed on the same plane and communicate with each other;

[0008] The abutting element includes a connecting part and a limiting block disposed on the connecting part;

[0009] The width of the first through hole is smaller than that of the second through hole; the limiting block can pass through the second through hole into the first cavity and move to the corresponding position of the first through hole to achieve limiting. Both the first and second through holes are connected to the first cavity; the different widths of the first and second through holes cooperate with the limiting block to complete the mutual limiting or release of the limiting state between the buckle body and the abutment element. Since the width of the first through hole is smaller than that of the second through hole, the limiting block can pass through the second through hole and extend into the first cavity. Since the first and second through holes are connected, sliding the limiting block moves it to the same axis as the first through hole. Since the width of the first through hole is smaller than the axial projection width of the limiting block, the limiting block cannot move axially from the first through hole to the outside of the buckle body. When the buckle body and the abutment element are in a mutually limiting state, and it is necessary to release the limiting state, the limiting block is moved to a state where its axial direction is coaxial with the second through hole, thereby releasing the limiting state between the buckle body and the abutment element. This connection method is simple, the limiting block extends into the buckle body, the overall structure is small, and the limiting block is connected to the object through the connecting part, so that there is no relative movement between the limiting block and the object, thereby avoiding the problem of surface wear caused by relative movement between the buckle body and the object; when the limiting block is connected to the buckle body, since the limiting block does not rotate relative to the object, the problem of the buckle body being driven and the shoulder strap rotating is avoided.

[0010] Preferably, the connecting part is connected to the first connecting block on the side away from the limiting block. Specifically, this is achieved through a threaded connection; wherein the fabric of the bag can be clamped between the first connecting block and the connecting part, or the first connecting block can be directly fixed to a component, such as the surface of a camera; thus fixing the limiting block onto the object.

[0011] Preferably, both the first through hole and the second through hole are circular holes, with a rounded transition between them. The buckle body has first and second through holes of different widths on the same plane, which, in conjunction with the limiting block, connect or disconnect the buckle body from the object. This connection method is simple, and since the limiting hole area on the buckle body is flat, it effectively avoids the problem of wear caused by a small contact surface when the buckle body and the object come into contact.

[0012] Preferably, the cross-section of the limiting block is circular along the radial direction of the abutting element.

[0013] Along the radial direction of the contact element, the cross-section of the connecting part is circular, and the whole is cylindrical; thus, the connecting part and the limiting block form a "convex" shaped structure. This facilitates control over the contact or non-contact state within the limiting hole. Simultaneously, the small projected area of ​​the connecting part allows it to move freely within the limiting hole, thereby aligning the axial direction of the limiting block with the first or second through hole. This controls the limiting or contact limiting state. Since the area of ​​the limiting block is larger than that of the first through hole, it cannot axially disengage from the first through hole. When the limiting block moves to the second through hole, because its area is smaller, it cannot be limited by the second through hole, allowing it to move freely axially at the second through hole, thus releasing the limiting relationship between the two.

[0014] Preferably, the buckle body has a first cavity that extends through the buckle body. The adjusting buckle further includes a first limiting mechanism and / or a first connecting mechanism for connecting the shoulder strap, both located within the first cavity, to abut against and limit the shoulder strap. The first cavity extends through the buckle body, thus limiting the shoulder strap within the first cavity while simultaneously connecting it via the first connecting mechanism.

[0015] Preferably, the first limiting mechanism includes an adjusting rod that penetrates the first cavity, and a guide groove is provided on one or both sides of the buckle body to restrict the movement direction of the adjusting rod. The guide groove extends along the distribution direction of the second through hole and the first through hole in a direction that gradually moves away from the surface where the limiting hole is located to press the strap. One end of the guide groove is close to the upper end of the buckle body, and the other end of the guide groove is close to the lower end of the buckle body; the center line of the guide groove is arc-shaped; the adjusting rod moves under the guidance of the guide groove. When the adjusting rod moves close to the upper end of the buckle body, the adjusting rod clamps the shoulder strap between the adjusting rod and the upper surface of the first cavity, thereby abutting the shoulder strap and restricting its movement within the first cavity; when it is necessary to adjust the shoulder strap, the adjusting rod is moved close to the lower end of the buckle body, thereby releasing the restriction on the shoulder strap and facilitating its adjustment.

[0016] Preferably, the adjusting rod includes a rod body penetrating the first cavity, multiple circumferentially spaced protrusions on the rod body, a second connecting block at both ends of the rod body to prevent the rod body from dislodging from the outside of the first cavity, and a third connecting block. The length of the spaced protrusions extending axially along the rod body matches the width of the shoulder strap, and the spaced protrusions form a textured pattern to better limit the shoulder strap within the first cavity. The shoulder strap is clamped by the contact between the rod body and the upper surface of the first cavity, thereby limiting the shoulder strap. The distance the protrusions extend axially along the rod body does not exceed the first cavity. The third connecting block is specifically a nut, and the end of the rod body away from the second connecting block has a thread that connects to the nut. The adjusting rod is positioned above the limiting hole, and the two operate independently. Both the second and third connecting blocks are located outside the buckle body and projected axially along the rod body. The radial height of the projection surface of the second and third connecting blocks is greater than the width of the guide groove, with the extension direction of the guide groove as its length direction and the perpendicular direction of its length direction as its width direction.

[0017] Preferably, the second connecting block is integrally fixed to the rod body, and the third connecting block is threadedly connected to the rod body.

[0018] Preferably, the first connecting mechanism includes a hinge post with the buckle body located below, and a connecting ring with both ends hinged to the hinge post. One side of the hinge post abuts against the edge of the limiting hole, and the other side abuts against the opening edge of the first cavity and is flush with it. Both sides of the hinge post have hinge holes that hinge to the connecting ring. The hinge post is hollow and has one or more fourth through holes. This allows the shoulder strap to be connected to the connecting ring, and the connecting ring and hinge post are movably connected, facilitating connection to shoulder straps in different directions, or allowing the shoulder strap to rotate to different directions at the connection point of the connecting ring after connection, improving usability.

[0019] Preferably, the end face of the buckle body with the limiting hole is further provided with one or more third through holes. The third through holes communicate with the first cavity. In this technical solution, two third through holes are provided, respectively located on both sides of the limiting hole. Providing third through holes effectively reduces the overall weight of the buckle body and, during manufacturing, provides a channel for the electroplating solution to flow out, improving the electroplating quality.

[0020] This application has achieved beneficial technical effects:

[0021] This invention controls the connection between the buckle body and the object by mutually limiting or releasing the limiting unit and the abutting element. This connection method is simple. After the buckle body and the abutting element are connected, the abutting element extends into the buckle body and moves synchronously with the object. This prevents the abutting element connected to the object and the buckle body from shaking like in the prior art, which would cause wear on the surface of the object. This makes the overall size of the connection structure smaller and requires fewer components. The abutting element is connected to the object and does not shake relative to the object. It avoids the situation where the abutting element moves relative to the buckle body after being connected to the limiting unit, thereby avoiding the problem of shoulder strap rotation.

Detailed Implementation

[0031] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0032] The technical solution of this utility model will be described in detail below with specific embodiments.

[0033] Reference Figures 1 to 7 An adjustable buckle includes a buckle body 1 that can be connected to a shoulder strap, and a limiting unit disposed on the buckle body 1 and cooperating with an abutment element 2 to control the mutual limiting or release of the limiting between the two. The buckle body 1 is provided with a first cavity 11, in which the abutting element 2 is fixedly disposed on the object to be connected, such as a camera or a bag. The buckle body 1 connected to the shoulder strap is provided with a limiting unit. The connection between the buckle body 1 and the object is controlled by the mutual limiting or releasing of the limiting unit and the abutting element 2. This connection method is simple. After the buckle body 1 is connected to the abutting element 2, the abutting element 2 extends into the interior of the buckle body 1 and moves synchronously with the object. This prevents the abutting element 2 connected to the object from shaking and causing wear on the surface of the object, as is the case with hooks in the prior art. This makes the overall volume of the connection structure smaller and requires fewer components. The abutting element 2 is connected to the object and does not shake relative to the object. This avoids the situation where the abutting element 2 moves relative to the buckle body 1 after being connected to the limiting unit, thereby avoiding the problem of shoulder strap rotation.

[0034] The limiting unit includes limiting holes 3 of different sizes for controlling the limiting or releasing of the abutment element 2. The limiting holes 3 are connected to the first cavity. By setting different sizes of the limiting holes 3, the connection state between the limiting holes 3 and the abutment element is controlled to be mutually limiting or releasing, thereby controlling the connection state between the buckle body 1 and the abutment element 2. The limiting holes 3 and the abutment element 2 are axially aligned, thereby controlling whether the abutment element 2 and the limiting holes 3 can be disengaged in the axial direction or mutually limited. This connection method is simple, and after connection, the abutment element 2 extends into the buckle body 1, making the overall volume small. Moreover, there is no relative movement between the buckle body 1 and the abutment element 2, thus avoiding the problem of wear on the surface of the object.

[0035] The limiting hole 3 includes a first through hole 31 and a second through hole 32 that are disposed on the same plane and are interconnected with each other;

[0036] The abutting element 2 includes a connecting part 21 and a limiting block 22 disposed on the connecting part 21;

[0037] The width of the first through hole 31 is smaller than that of the second through hole 32; the limiting block 22 can pass through the second through hole 32 into the first cavity 11 and move to the corresponding position of the first through hole 31 to achieve limiting; both the first through hole 31 and the second through hole 32 are connected to the first cavity; the first through hole 31 and the second through hole 32 with different widths cooperate with the limiting block to complete the mutual limiting or release of the limiting state between the buckle body 1 and the abutment element 2. Since the width of the first through hole 31 is smaller than that of the second through hole 32, the limiting block 22 can pass through the second through hole 32 and extend into the first cavity. Since the first through hole 31 and the second through hole 32 are connected, the limiting block 22 can slide. Since the widths of the first through hole 31 and the second through hole 32 are both larger than the axial projection width of the connecting part 21, the connecting part 21 can move freely between the first through hole 31 and the second through hole 32, allowing the limiting block 22 to move freely between them. When the axial direction of the limiting block 22 is aligned with the first through hole 31, the limiting block 22 cannot move axially from the first through hole 31 to the outside of the buckle body 1 to complete the mutual limiting state between the buckle body 1 and the abutment element 2. When it is necessary to release the limiting state, the limiting block 22 is moved to a position where its axial direction is aligned with the second through hole 32, thereby releasing the limiting state between the buckle body 1 and the abutment element 2. This connection method is simple. The limiting block 22 extends into the buckle body 11, and the overall structure is small. The limiting block 22 is connected to the object through the connecting part 21, so that there is no relative movement between the limiting block 22 and the object, thereby avoiding the problem of surface wear caused by relative movement between the buckle body 1 and the object. When the limiting block is connected to the buckle body 1, the limiting block 22 will not rotate relative to the object, thus avoiding the problem of the buckle body 1 being driven and the shoulder strap rotating.

[0038] The connecting part 21 is connected to the first connecting block 23 on the side away from the limiting block 22. Specifically, it is connected by threads; the first connecting block 23 and the connecting part 21 can clamp the fabric of the bag, or the first connecting block 23 can be directly fixed to the component, such as the surface of a camera, so that the limiting block 22 is fixedly set on the object. The abutting element is specifically a T-shaped nail that can be connected to the bag, and is fixed to the bag by screwing it on. The nail head is the limiting block 22, and the buckle body uses the shape of the limiting hole below to lock the limiting block 22 to achieve the fixing function.

[0039] Both the first through hole 31 and the second through hole 32 are circular holes, and an arc transition is provided between the first through hole 31 and the second through hole 32. The first through hole 31 and the second through hole 32 with different width dimensions are formed on the same plane of the buckle body 1, which cooperate with the limiting block 22 to complete the connection or disconnection between the buckle body 1 and the object. This connection mode is simple, and the position where the limiting hole 3 is provided on the buckle body 1 is a plane, which can effectively avoid the problem of wear caused by the small contact surface when the buckle body 1 and the object contact each other.

[0040] Along the radial direction of the abutting element 2, the cross-section of the limiting block 22 is circular.

[0041] Along the radial direction of the abutting element 2, the cross-section of the connecting portion 21 is circular, and the connecting portion 21 is cylindrical as a whole; so that the connecting portion 21 and the limiting block 22 integrally form a "convex" shaped structure. It is convenient to control the abutting or non-abutting state in the limiting hole 3. Meanwhile, the projection area of the connecting portion 21 is small, and the connecting portion 21 can move freely in the limiting hole 3 to drive the axial direction of the limiting block 22 to correspond to the first through hole 31 or the second through hole 32, thereby controlling the limiting state or the released limiting state. The area of the limiting block 22 is larger than that of the first through hole 31, so that the limiting block 22 cannot axially escape to the outside from the position where the first through hole 31 is provided. When the limiting block 22 moves to the position where the second through hole 32 is provided, since the area of the limiting block 22 is smaller than that of the second through hole 32, the limiting block 22 cannot be limited by the second through hole 32, so that the limiting block 22 can move axially freely at the position where the second through hole 32 is provided, thereby releasing the limitation of the two.

[0042] The buckle body 1 is provided with a first cavity 11, the first cavity 11 penetrates through the buckle body 1, and the adjustment buckle 1 further comprises a first limiting mechanism 4 for limiting a shoulder strap by abutting and / or a first connecting mechanism 5 for connecting the shoulder strap, which are arranged in the first cavity 11. Wherein the first cavity 11 penetrates through the buckle body 1, so that the shoulder strap is limited in the first cavity 11 and connected through the first connecting mechanism 5;

[0043] The first limiting mechanism 4 includes an adjusting rod 41 that passes through the first cavity 11, and a guide groove 12 that limits the movement direction of the adjusting rod 41 is provided on one or both sides of the buckle body 1. The guide groove 12 extends along the distribution direction of the second through hole 32 and the first through hole 31 in a direction that gradually moves away from the surface where the limiting hole 3 is located to press the strip. The guide groove 12 is provided on one or both sides of the buckle body 1. In this technical solution, the guide groove 12 is symmetrically arranged on both sides of the buckle body 1, corresponding to the two ends of the adjusting rod 41 respectively. One end of the guide groove 12 is close to the upper end of the buckle body 1, and the other end of the guide groove 12 is close to the lower end of the buckle body 1. The center line of the guide groove 12 is arc-shaped. The adjusting rod 41 moves under the guidance of the guide groove 12. When the adjusting rod 41 moves close to the upper end of the buckle body 1, the adjusting rod 41 clamps the shoulder strap between the adjusting rod 41 and the upper surface of the first cavity 11, thereby abutting the shoulder strap and restricting the movement of the shoulder strap in the first cavity 11. When it is necessary to adjust the shoulder strap, the adjusting rod 41 is moved close to the lower end of the buckle body 1, thereby releasing the restriction on the shoulder strap and facilitating the adjustment of the shoulder strap.

[0044] The adjusting rod 41 includes a rod body 411 penetrating the first cavity 11, a plurality of circumferentially spaced protrusions 412 on the rod body 411, a second connecting block 413 and a third connecting block 414 disposed at both ends of the rod body 411 to prevent the rod body 411 from dislodging from the outside of the first cavity 11. The length of the spaced protrusions 412 extending axially along the rod body 411 matches the width of the shoulder strap, and the spaced protrusions 412 form a textured pattern to better limit the shoulder strap within the first cavity 11; the shoulder strap is limited by the abutment and clamping between the rod body 411 and the upper end plane of the first cavity 11, wherein the distance of the protrusions 412 extending axially along the rod body 411 does not exceed the first cavity 11; the third connecting block 414 is specifically a nut, and the end of the rod body 411 away from the second connecting block 413 is provided with a thread 415 that is threadedly connected to the nut. The rod 411 of the adjusting rod 41 passes through the first cavity 11 of the buckle body 1, and is then connected to the thread 415 by the third connecting block 414, allowing the adjusting rod to slide freely within the buckle body 1. The adjusting rod 41 is positioned above the limiting hole 3, and the two operate independently. The second connecting block 413 and the third connecting block 414 are both located outside the buckle body 1 and projected along the axial direction of the rod 411. The radial height of the projection surface of the second connecting block 413 and the radial height of the projection surface of the third connecting block 414 are both greater than the width of the guide groove 12, with the extension direction of the guide groove 12 as its length direction and the perpendicular direction of its length direction as its width direction.

[0045] The second connecting block 413 is integrally fixed with the rod body 411, and the third connecting block 414 is threadedly connected to the rod body 411.

[0046] The first connecting mechanism 5 includes a hinge post 51 disposed below the buckle body 1 and a connecting ring 52 hinged to the hinge post 51 at both ends. One side of the hinge post 51 abuts against the edge of the limiting hole 3, and the other side of the hinge post 51 abuts against the opening edge of the first cavity 11 and is flush with it. Both sides of the hinge post 51 are provided with hinge holes 53 that are hinged to the connecting ring 52. The hinge post 51 is hollow and has one or more fourth through holes 55. The connecting ring 52 has symmetrically arranged flanges 521, and the ends of the flanges 521 have openings 522. By striking the flanges 521 at both ends, the connecting ring 52 is hinged to the hinge post through the openings 522, allowing the connecting ring 52 to rotate relative to the hinge post 51. The shoulder strap can be connected to the connecting ring 52, and the connecting ring 52 and the hinge post 51 are movably connected, which facilitates connection with shoulder straps in different directions, or allows the shoulder strap to rotate to different directions at the connection point of the connecting ring 52 after the shoulder strap is connected, so as to improve the flexibility of use.

[0047] The end face of the buckle body 1 with the limiting hole 3 is also provided with one or more third through holes 13. The third through holes 13 are connected to the first cavity 11. In this technical solution, two third through holes 13 are provided, respectively located on both sides of the limiting hole. Providing the third through holes 13 and the fourth through holes 55 can effectively reduce the overall weight of the buckle body 1, and provide a channel for the electroplating solution to flow out during the manufacturing process, thereby improving the electroplating quality.

[0048] This technical solution is an adjustment buckle applied to shoulder straps; its specific application is as an adjustment buckle for shoulder straps of bags and cameras.

[0049] The upper end of the buckle body 1 is provided with a first end face 14, and the surface of the first end face 14 can be added with patterns formed by processes such as laser processing and adhesion.

[0050] During assembly or use, the webbing is fixed at the connecting ring 52, which connects the webbing and the buckle body. The webbing that needs adjustment is then passed through the first cavity 11 of the buckle body 1, traversing the entire buckle body. It is then slid to the left by the assembled adjusting rod 41 to form the second state. (See [reference]). Figure 7 The adjusting rod moves upward along the track, i.e., the guide groove 12. By reducing the distance between the adjusting rod 41 and the inner wall of the first cavity 11, the friction is increased, thus pressing the webbing and securing it. Similarly, the adjusting rod 41 moves downward along the track, i.e., the guide groove 12, increasing the distance between the adjusting rod 41 and the inner wall of the first cavity 11, forming the first state. See [link / reference]. Figure 6This loosens the webbing, allowing for back-and-forth adjustment. The other end of the shoulder strap buckle is formed by a limiting hole 3 located below the buckle body 1 and an abutment element 2 assembled to another main body. The abutment element's special I-beam shape, wider at both ends and narrower in the middle, allows for locking. (See attached image.) Figure 6 The design of the second through hole 32 allows the limiting block 22 to disengage, meaning it is larger than the cross-sectional dimensions of the limiting block. When the assembled abutment element 2 slides into the first through hole 31, the connecting ring 52 with the webbing threaded on it is lifted to raise the entire assembled buckle body 1. The downward force generated by the weight of the object connected to the abutment element 2 utilizes the second through hole 32 to lock the abutment element 2 in place, thus fixing the buckle body 1 and the abutment element 2 together. (See [reference]). Figure 7 Similarly, during disassembly, the contact element 2 can be slid to the second through hole 32 to be disassembled. See [link / reference]. Figure 6 .

[0051] The buckle body 1 features two adjustment designs. First, the tension of the webbing is adjusted by the space between the adjusting rod 41 and the upper wall of the first cavity 11, thus limiting the webbing's position. The rod 441 has protrusions 412 forming a texture, which increases friction with the webbing when it is engaged. The buckle body 1 has first through holes 31 and second through holes 32 of different widths, allowing it to be concealed under the webbing or connected to the contact element 2 via a blind insertion mechanism, making operation convenient.

[0052] In addition, there are two perforations on the main body of the buckle: the third through hole 13 and the fourth through hole 55. These perforations reduce the weight of the material, and if an alloy material is used, the perforations also allow the electroplating solution to flow out, increasing the quality of the electroplating.

[0053] During use, the adjustment buckle of this technical solution integrates detachment and adjustment, reducing the number of required components, simplifying the structure, and concealing the detachment part under the buckle body, thus reducing the overall product area. In use, the buckle body 1 can be detached first and then the webbing adjusted, or the webbing adjusted first and then the buckle body 1 detached; either method is acceptable, making wearing and use more convenient. In this technical solution, the integrated shoulder strap buckle achieves the dual function of adjusting and detaching the webbing.

[0054] Compared with existing snap-on bag buckles, this technical solution features a smaller product size and a hollowed-out design on the reverse side, reducing product weight. During use, the detachable part is hidden inside the webbing, that is, inside the buckle body, avoiding wear and tear on the webbing and the surface of products such as bags. Combining webbing adjustment with detachable parts for products such as bags enhances functionality compared to existing hooks. Furthermore, the connection method with the T-shaped pin is smaller and easier to conceal than the ring used with hooks. The surface of the buckle body 1 can be customized with patterns for an aesthetically pleasing design.

[0055] This technical solution allows for the adjustment and detachment of the product's shoulder straps, enabling multi-functional use and integrating detachment and adjustment to meet various daily usage scenarios. This solution combines the webbing adjustment function with a buckle, allowing for the detachment of the webbing.
