Background technique

The use of buckles is very common nowadays, and different types of buckles have different fastening methods, and multiple buckles are applied to backpacks, shoe bodies, garments or other items that can be fixed with ropes at the same time. The buckle usually uses a rope to pass through it, so that the heads at both ends of the rope can be passed through, and then a buckle is inserted from the two heads, so that the buckle can move along the surface of the rope for adjustment. Use as the opening size on items such as backpacks, shoe bodies or ready-to-wear.

Please refer to Fig. 10, most backpacks are used with this type of buckle nowadays. The existing rope buckle includes a button A, a female buckle B and a spring C, wherein the button A is designed in a stepped shape, and A perforation A2 is provided on the column body A1, and a protrusion A3 is respectively extended on both sides of the bottom edge of the perforation A2, and a fixed column A4 is provided at the bottom of the button A, and the female button B has a hollow receiving body B1, wherein The empty part forms an accommodating space B2, and a protruding positioning column B3 is provided at the bottom of the accommodating space B2, and guide slopes B4 are respectively provided on the two side walls away from the top edge of the positioning column B3, and then the hollow accommodating body There is a relative through-hole B5 on the outside of B1, and the spring C is positioned between the button A and the female buckle B, and one end of the spring C is sleeved on the fixed column A4 of the button A, and the other end is sleeved on the female buckle B After the positioning post B3 of the button is mounted, the spring C can be accommodated in the accommodation space B2 of the female button B. When the user presses the button A, the protrusion A3 of the button A will be pushed along the guide slope B4 of the female button B. Insert the hole A2 and the two through holes B5 on the female buckle B to align with each other, and then insert the head end of the rope, and the rope can be pressed against the through hole A2 and the female buckle B by the elastic restoring force of the spring C. When the through hole B5 of the buckle B is positioned, the overall structure of the existing rope buckle can be completed.

However, the existing rope buckle needs to put the central column A1 of the button A into the accommodation space B2 of the female buckle B as a whole, so that the through hole A2 and the through hole B5 can form a state of mutual alignment or misalignment for clamping For the rope, the structural design of the button A makes the overall volume of the female button B relatively large and the appearance is quite abrupt; As a result, the various parts of the components are separated from each other and easily lost. When reassembling, the spring C still needs to be re-aligned and assembled on the button A and the female button B, which causes inconvenience and trouble in operation and use. The rope buckle is very easy to increase the difficulty of its assembly due to dimensional errors, which will cause it to shake easily and fall off when pressed.

Referring again to Figures 11 and 12, another existing rope buckle is mainly provided with a fastening device D1 in the hollow part of the seat body D, and is sleeved on the boss D12 at the top of the connecting plate D11 in the fastening device D1. There is a spring C, and the notch D21 on the bottom side of the button D2 is inserted above the connecting plate D11 supported laterally by the base D.

Not only does the overall number of components increase, but the required man-hours and costs are greatly increased. When the button D is pressed repeatedly for a long time, it is easy to cause the spring C to become elastic. Fatigue, so that the button D cannot be reset immediately after release, and because the elastic arm D13 is not provided with any structure that can be tightly interfered with the rope E, the elastic arm D13 and the rope E tend to slide relative to each other, and cannot be firmly clamped. Tighten the rope E, this is the direction where those who are engaged in this industry urgently need to study and improve.

The one-piece structure design not only makes the overall structure quite simple, but also does not need to install elastic components to perform tight interference positioning by hand-pulling the rope 3 methods to simplify the manufacturing process and effectively save costs, thereby achieving stable structure, easy operation and low cost Effect.

When the user wants to loosen the rope 3, he only needs to move upwards on the pushing part 24 at the two sides of the head 21 of the clamping body 2, and the teeth 221 at the two sides of the positioning column 22 will move upwards, and The predetermined distance between the two side walls 111 of the channel 11 becomes larger, which means that it can be released on the rope 3 to form a separated state. After the docking seat 1 cannot move arbitrarily, pull the tooth portion 221 of the positioning column 22 upwards on the rope 3 so that the clamping body 2 can be displaced simultaneously, and the tooth portion 221 of the positioning column 22 is connected to the two side walls 111 of the channel 11. If the predetermined distance between them becomes larger, the action of releasing the rope 3 can also be achieved, and the tightness of the rope 3 can be adjusted, and the concave shape can be formed between the top of the rope 3 and the two perforations 211 of the head 21. The stop positioning is formed in the slot 212, so that the clamping body 2 will not come out of the rope 3 and cause loss, so that the user can quickly adjust the rope 3 to tighten or release it on the combination 4 according to various purposes and places of use The degree of tightness is beneficial to the fixing of the combination 4 or the adjustment of the size of the opening for use, thereby improving its overall use function and effect, and making the product more competitive.
