Description

Technical Field

[0001] This utility model relates to the field of flip-top cord buckle technology, and in particular to a concealed square flip-top cord buckle. Background Technology

[0002] In today's era that emphasizes both design aesthetics and practical functionality, every detail in the clothing and bag industry has become the focus of attention for brands and consumers. Traditional cord buckle designs often affect the overall aesthetics due to their exposed nature, and also suffer from problems such as inconvenience in adjustment and insufficient durability. In particular, the copper spring tension is not up to standard, which brings many inconveniences to the user experience.

[0003] A square flap cord buckle is known in Chinese Patent Publication No. CN215124922U. The cord buckle can be rotated along the connecting strip through the upper cover to be fastened inside the lower cover. When fastened, the braided cord hole on the upper cover and the braided cord hole on the lower cover coincide, which can be directly attached to the fabric for a beautiful appearance and is hidden inside the fabric interlayer.

[0004] However, after the cord is threaded, customers can attach it to the fabric with an adhesive backing and heat it to achieve a concealed effect. The connection between the cord and the fabric is not secure enough, and it may cause inconvenience or detachment during use. Secondly, in the concealed square flap cord design, the braided cord needs to be frequently adjusted through the narrow gap inside the flap. During this process, the braided cord comes into direct contact with the metal or plastic edge of the flap, making the cord prone to wear. After prolonged use, this not only affects the appearance but may also cause the cord to break, reducing product safety. Furthermore, the flap may loosen after frequent pressing and opening, affecting the tightness and stability of the latch. This not only reduces the convenience of adjustment but may also cause accidental loosening during use, creating a safety hazard. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1-4 This utility model provides a technical solution: a concealed square flip-top cord buckle, including a cord buckle base 1 and a cord buckle top cover 2. The cord buckle base 1 and the cord buckle top cover 2 are connected by a connecting strip 3. The cord buckle base 1 is provided with a mounting frame 4 on its top. The cord buckle top cover 2 is provided with a snap-fit ​​post 5 that matches the mounting frame 4 on its top. The mounting frame 4 is provided with a cable routing groove 6 inside the cord buckle base 1 on its outer side. The mounting frame 4 is provided with braided rope holes 7 on both sides inside its inner side. A locking structure is provided below the braided rope holes 7 on the outer side of the mounting frame 4. The snap-fit ​​post 5 is provided with a guide groove 8 that matches the braided rope holes 7 inside its inner side. A clamping mechanism is provided inside the guide groove 8. The snap-fit ​​post 5 is provided with a spring hole 9 on its top. The cord buckle base 1 and the cord buckle top cover 2 are provided with a fabric connecting mechanism at their bottoms.

[0026] Reference Figure 1 , Figure 4The mounting frame 4 has a locking block 16 located on the upper part inside, and a locking groove 17 matching the locking block 16 is located on the lower part of the outer side of the locking post 5. The cable routing groove 6 has a silicone ring pad 18 inside. The silicone ring pad 18 significantly reduces the direct friction between the braided rope and the hard material, thereby reducing wear. The locking structure includes a movable hole 10, a movable plate 11, a locking block 12, a locking groove 13, a protruding rod 14, and a first return spring 15. The movable hole 10 is located on the outer side of the mounting frame 4 below the braided rope hole 7. The movable plate 11 is located inside the movable hole 10. A locking block 12 is located on the side of the movable plate 11 at one end, and multiple sets of protruding rods 14 are located on the top of the movable plate 11 at the other end. A locking groove 13 matching the locking block 12 is located on the upper side of the locking post 5. A first return spring 15 is located inside the spring hole 9. This helps to reduce the wear of the locking block 16 and the locking groove 17, ensuring the tightness and stability of the engagement between the rope buckle base 1 and the rope buckle cover 2.

[0027] In practical implementation, the concealed square flip-top cord buckle is used by first inserting the first return spring 15 into the spring hole 9. Then, the cord buckle cover 2 can rotate along the connecting strip 3 to the top of the cord buckle base 1, thereby enabling the mounting frame 4 and the locking post 5 to be locked together through the locking block 16 and the locking groove 17. After locking, under the elastic action of the first return spring 15, the braided cord hole 7 and the guide groove 8 overlap, and the locking block 12 and the locking groove 13 also overlap. The cord buckle can be manually moved through the protrusion 1. 4. Push the movable plate 11 so that the locking block 12 is locked into the locking groove 13, thereby locking the rope buckle cover 2 and the rope buckle base 1 together. Then, the braided rope is passed through the braided rope hole 7 and the guide groove 8, and then passes out from the wiring groove 6, thus easily completing the assembly of the rope buckle. Subsequently, the customer can add an adhesive lining to the fabric and fix the rope buckle inside the fabric by high temperature bonding to achieve a hidden installation. Through the above operations, not only is the installation process simplified, but the installation efficiency is also improved.

[0028] Example 2

[0029] Reference Figure 5 , Figure 6This embodiment is an optimization based on Embodiment 1. The clamping mechanism includes a through groove 19, a clamping plate 20, a rubber pad 21, a second return spring 22, a baffle 23, a slide 24, an adjustment button 25, a shock absorber 26, an arc-shaped spring 27, a limiting block 28, and a bayonet 29. The rope buckle cover 2 and the guide groove 8 are provided with a through groove 19 that communicates with each other. The guide groove 8 is provided with a clamping plate 20, and the side of the clamping plate 20 is provided with a rubber pad 21. The rubber pad 21 is provided to further reduce the wear of the clamping plate 20 on the braided rope. Furthermore, a second return spring 22 is provided below the clamping plate 20 inside the through groove 19, and a baffle 23 is provided on the side of the second return spring 22. Slides 24 are provided on both sides of the inside of the through groove 19, and matching adjustment buttons 25 are provided inside the slides 24 in a movable connection. A shock absorber 26 is provided on the top of the adjustment button 25, and arc-shaped spring pieces 27 are provided on both sides of the shock absorber 26 above the adjustment button 25. Limiting blocks 28 are provided on the sides of the arc-shaped spring pieces 27, and a bayonet 29 matching the limiting block 28 is provided on the inner wall of the through groove 19.

[0030] Reference Figure 2 , Figure 3 The connecting mechanism includes a locking hole 30, a locking rod 31, and a square fixing piece 32. Multiple sets of locking holes 30 are provided below the rope buckle base 1 and the rope buckle cover 2. A square fixing piece 32 is provided below the locking hole 30, and a locking rod 31 matching the locking hole 30 is provided on the top of the square fixing piece 32 for movable locking.

[0031] In specific implementation, when the concealed square flip-top cord buckle is installed and adjusted, as in the embodiment, after folding and locking, the upper locking rod 31 and the fabric are pressed and locked into the locking hole 30 by the square fixing piece 32 for further fixation. This ensures the stability of the connection between the cord buckle and the fabric while avoiding damage to the fabric. When the braided cord needs to be fine-tuned, the cord buckle base 1 and the cord buckle cover 2 lock together. First, press the adjustment button 25. The adjustment button 25 pushes the arc-shaped spring piece 27 and the limiting block 28 downwards, causing the limiting block 28 to disengage from the locking hole 29. At the same time, under the elastic action of the second return spring 22... Quickly lift the clamp 20 and adjustment button 25 upwards. The shock absorber 26 on the side of the adjustment button 25 can effectively reduce the elastic impact of the second return spring 22, which helps to extend the service life of the flap cord buckle. Then, since the braided cord hole 7 and the guide groove 8 overlap, the braided cord can be adjusted by manually pulling it. After adjustment, press the adjustment button 25 to make the limiting block 28 on the side of the arc-shaped spring piece 27 engage with the bayonet 29, thereby compressing the second return spring 22 and pushing the clamp 20 to clamp the outside of the braided cord for fastening. Through the above operation, the adjustment is more convenient and precise, and at the same time, the wear on the braided cord is further reduced.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
