Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to an anti-slip fastener. Background Technology

[0002] D-ring buckles are a common accessory found on backpacks and shoulder straps, typically made of plastic or metal. Backpacks and shoulder straps usually have shoulder straps, and the webbing on these straps passes through the D-ring buckle. Adjusting the strap length via the webbing allows for customization to fit different body types. Common D-ring buckles are generally not very stable; if the backpack is too heavy, or if a child in a baby carrier is heavy, the webbing may loosen, and in severe cases, the buckle may detach. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an anti-slip fastener. To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0004] An anti-slip fastener includes a first fastener and a second fastener that can be rotatably opened and closed. The ends of the first fastener and the second fastener are provided with connecting portions, which are rotatably connected. At least one locking portion is provided between the first fastener and the second fastener. The first fastener and the second fastener have an open state and a closed state. In the closed state, the first fastener and the second fastener are tightly fitted together and are locked together by the locking portion. In the open state, the first fastener or the second fastener disengages from the locking portion and rotates open about the connecting portion as the axis.

[0005] Furthermore, the lower end of the first fastener has two stops on both sides, and the two stops form an assembly groove with the first fastener. The assembly groove is adapted to the outer contour of the second fastener, and the second fastener is rotatably installed in the assembly groove.

[0006] Furthermore, the connecting part includes protruding shafts on both sides of the second fastener and shaft holes on both sides of the mounting groove that adapt to the shafts, so that rotational opening and closing can be achieved by rotating the shafts within the shaft holes.

[0007] Furthermore, a guide portion is provided on the shaft.

[0008] Furthermore, the first and second fasteners are hollowed out.

[0009] Furthermore, the first buckle has a first block at the hollowed-out area, which divides the hollowed-out area into a first upper cavity and a second upper cavity; the second buckle has a second block at the hollowed-out area, which divides the hollowed-out area into a first lower cavity and a second lower cavity; when the first buckle or the second buckle is closed, the first block is placed at the center above the second lower cavity, and the width of the first block is smaller than that of the second lower cavity.

[0010] Furthermore, the top and bottom surfaces of the first block are provided with anti-slip textures, and the upper surface of the second fastener is provided with anti-slip textures.

[0011] Furthermore, the locking part includes a locking groove on the inner wall of the stop block and an annular locking block on the outer wall of the second fastener. The locking block is adapted to the locking groove and is fixed by being fastened into the locking groove.

[0012] Furthermore, the second fastener has a rotation limiting part at one end near the connecting part.

[0013] Furthermore, the second fastener has a buckle handle at the end furthest from the connecting part.

[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0015] This utility model includes a first buckle and a second buckle that can be rotated and opened. The webbing is wrapped around the first buckle and the second buckle in an S-shape. The first buckle and the second buckle rotate and close to clamp the webbing, making the webbing less likely to loosen. Traditional day buckles only wrap the webbing around one buckle. This design combines the method of wrapping the webbing around two buckles with the method of clamping the webbing with two buckles, which makes the stability stronger. The webbing is not easy to loosen during use and has stronger stability.

[0016] The ends of the first and second fasteners are provided with connecting parts, which are rotatably connected. At least one locking part is provided between the first and second fasteners. After closing, the locking part further strengthens the connection between the first and second fasteners, preventing them from opening automatically due to external forces during use, so as to avoid giving consumers a bad experience.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, an anti-slip fastener includes a rotatable first fastener 1 and a second fastener 2. A webbing is wound in an S-shape around the first fastener 1 and the second fastener 2. The first fastener 1 and the second fastener 2 rotate to close and clamp the webbing, making it less prone to loosening and providing strong stability. The ends of the first fastener 1 and the second fastener 2 are provided with connecting portions 3, which rotatably connect the two fasteners. At least one locking portion 4 is provided between the first fastener 1 and the second fastener 2. After closing, the locking portion 4 further reinforces the connection between the first fastener 1 and the second fastener 2, preventing them from automatically opening due to external forces during use, thus avoiding a negative experience for consumers.

[0024] The first buckle 1 and the second buckle 2 have an open state and a closed state: In the closed state, the first buckle 1 and the second buckle 2 are tightly fitted together, and the webbing on the baby carrier or backpack is wrapped around the first buckle 1 and the second buckle 2. The first buckle 1 or the second buckle 2 rotates to close and tightly clamp the webbing, forming a lock through the locking part 4 to prevent opening; In the open state, the first buckle 1 or the second buckle 2 is manually pried open, the locking part 4 is unlocked, and the first buckle 1 or the second buckle 2 rotates to open around the connecting part 3 as the axis point. After opening, the length of the webbing can be adjusted or removed.

[0025] The first fastener 1 has two stops 5 on both sides at its lower end. The stops 5 on both sides form an assembly groove 6 with the first fastener 1. The assembly groove 6 is adapted to the outer contour of the second fastener 2. The second fastener is rotatably installed in the assembly groove 6. After closing, the second fastener 2 is located in the assembly groove 6, which can restrict the left and right movement of the second fastener 2 and prevent damage.

[0026] The connecting part 3 includes the protruding shaft post 7 on both sides of the second fastener 2 and the shaft hole 8 on both sides of the mounting groove 6 that is adapted to the shaft post 7. They are rotatably connected by a shaft connection. When rotating to open and close, the shaft post 7 rotates in the shaft hole 8. The structure is relatively simple and convenient for manufacturers to produce.

[0027] The shaft post 7 is provided with a guide part 9, which is an inclined surface that guides the installation of the first fastener 1 and the second fastener 2. The first fastener 1 and the second fastener 2 are made of plastic. During installation, the shaft post 7 opens the assembly groove 6, and the guide part 9 moves along the inner wall of the assembly groove 6 until the shaft post 7 is fastened into the shaft hole 8, which helps the user with installation.

[0028] The first buckle 1 and the second buckle 2 are hollow. The hollow part of the first buckle 1 is provided with a first block 10, which divides the hollow part to form a first upper cavity 11 and a second upper cavity 12. The webbing passes through the second upper cavity 12 into the first upper cavity 11 and wraps around the first block 10. The hollow part of the second buckle 2 is provided with a second block 13, which divides the hollow part to form a first lower cavity 14 and a second lower cavity 15. When the first buckle 1 and the second buckle 2 are closed, the first block 10 is placed in the center above the second lower cavity 15, and the width of the first block 10 is smaller than that of the second lower cavity 15, so gaps are formed on both sides for the webbing to pass through. When opening for installation, the webbing is inserted between the first buckle 1 and the second buckle 2, first inserted into the second upper cavity 12 and placed above the first block 10, then attached to the first block 10 and inserted downward into the second lower cavity 15 and placed below the second block 13, and finally attached to the second block 13 and inserted into the first lower cavity 14 and out through the first upper cavity 11.

[0029] The top and bottom surfaces of the first block 10 are provided with anti-slip textures 19. When the webbing is wrapped around the first block 10, the anti-slip textures 19 can play an anti-slip role, and the webbing is not easy to loosen. The upper surface of the second buckle 2 is also provided with anti-slip textures 19, located on the top surface of the second block 13 and the opening and closing end of the second buckle 2. When the webbing is wrapped around the second block 13 and clamped between the first buckle 1 and the second buckle 2, it can play an anti-slip role, further increasing stability.

[0030] The locking part 5 includes a locking groove 16 on the inner wall of the stop block 5 and an annular locking block 17 on the outer wall of the second fastener 2. The locking block 17 is adapted to the locking groove 16. When the first fastener 1 and the second fastener 2 are closed, the locking block 17 is engaged in the locking groove 16 to form a fixed position, preventing it from opening automatically due to external force, and can emit a feedback prompt sound to remind the user to complete the engagement. The arc-shaped contour design of the locking block 17 can play a guiding role when opening and closing.

[0031] The second fastener 2 has a rotation limiting part 18 at one end near the connecting part 3 to limit the maximum rotation angle and prevent damage to the product from excessive opening or closing. The rotation limiting part 18 is an arc surface. When it is opened by rotation, the arc-shaped outline will not touch the first fastener 1, and it can rotate freely within the arc range. When the rotation is opened to a certain extent and crosses the arc surface of the rotation limiting part 18, the plane of the second fastener 2 abuts against the first fastener and cannot continue to rotate.

[0032] The length of the first buckle 1 is greater than that of the second buckle 2. The end of the second buckle 2 away from the connecting part 3 is provided with a concave handle 20, which makes it convenient for the user to insert their fingers into the handle 20 and use external force to release the locking state of the locking part 4. The locking block 17 can be rotated open after it is disengaged from the locking groove 16.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
