Description

One Piece Cord Lock

technical field

The utility model relates to a one-piece rope buckle, especially after the first pressing part and the second pressing part are pressed, and the elastic restoring force of the connecting part is used after passing the rope through the interposition holes and hollow holes aligned with each other. , so that the rope is squeezed and positioned due to the misalignment of the piercing hole and the hollow hole, and the cost is reduced through a single body with a simple structure.

Background technique

At present, the use of buckles is very common, and different types of buckles have different fastening methods, each with its own characteristics and scope of application, and can be used on shoes, bags or clothing at the same time, and buckles are usually Use the rope to pass through it, and pass the head of the two ends of the rope out, and then use a buckle to fit in from the outer diameter of the head, so that the buckle can move along the outer diameter surface of the rope, so as to adjust the shoes , bag or clothing opening size to use.

Please refer to Figure 7, which is an existing three-dimensional appearance diagram. It can be clearly seen from the figure that the rope buckle includes a button A, a female button B and a spring C, wherein the button A is a stepped design, and its central column The body A1 is to open a perforation A2, and at the level of the lower end of the perforation A2, a convex block A3 with a flat top and an arc surface below is extended, and a fixed post A4 is protruded from the bottom of the button A; while the female button B has a The hollow housing body B1 has a housing space B2 formed in the hollow part, and a positioning column B3 is protruded from the bottom of the housing space B2, and a guide slope B4 is convexly provided on the two sides away from the top of the positioning column B3, and the hollow housing The two sides of the housing B1 are provided with corresponding through holes B5.

The spring C is located between the button A and the female buckle B. One end of the spring C is sleeved on the fixing post A4 of the button A, and the other end is sleeved on the positioning post B3 of the female buckle B. The spring C is housed in the In the vacant space B2 of the female button, when pressing, the protrusion A3 of the button A is pushed along the second guide inclined surface B4 protruding from the top of the inner diameter of the female button B, so that the perforation A2 corresponds to the second through hole B5 of the female button B Relatively positive, and then penetrate the two heads of the preset rope, so that the button A can fix the rope to the corresponding perforation A2 and through hole B5 of the button A and the female button B through the reset elastic force of the spring C place, that is to complete the overall assembly and use.

However, if the above-mentioned structure accidentally slips out of the through hole and the through hole B5 of the rope buckle, the components will be separated from each other and easily lost. When reassembling, the spring C must be re-aligned with the button A and the female buckle. On B, it further causes inconvenience and confusion in use and operation, and the overall structure is complicated and there are many components, so the manufacturing process is difficult, which further increases the manufacturing time and cost.

Therefore, how to solve the problems and deficiencies of the existing rope buckles is the direction that relevant manufacturers engaged in this industry are eager to study and improve.

Utility model content

In view of this, in view of the above-mentioned problems and deficiencies, the inventor of the utility model has collected relevant information, evaluated and considered in many ways, and based on years of experience accumulated in this industry, through continuous trial and modification, he designed this kind of Utility model patent for one-piece cord buckle.

The main purpose of the present utility model is that the first pressing part and the second pressing part of the main body are connected with connecting parts on the opposite inner sides, and the connecting parts are respectively formed with two sides of the first pressing part and two sides of the second pressing part. When the bending part of the insertion hole and the turning part with the hollow hole are pressed to elastically deform the connecting part, the insertion hole and the hollow hole are in alignment, and the body can be placed on the rope. The surface of the outer diameter of the cable moves, and through the elastic restoring force of the connecting part, the piercing holes and the hollow holes are misaligned to form a tight pinching position between the rope and the piercing holes and the hollow holes. Since the whole only needs a single component , so as to achieve the purpose of reducing costs.

Detailed ways

In order to achieve the above-mentioned purpose and effect, the technical means and the structure adopted by the utility model are hereby drawn to illustrate in detail the features and functions of the preferred embodiments of the utility model as follows, in order to fully understand.

Please refer to Fig. 1 and Fig. 2, which are the three-dimensional appearance diagram of the utility model and the side view before pressing. It can be clearly seen from the figures that the body 1 of the utility model is made of elastic plastic material , and the main body 1 includes a first pressing portion 11 and a second pressing portion 12 in the shape of a sheet or a plate, and the outer surface of the first pressing portion 11 is provided with a plurality of arrayed convex strips 111, and on the second pressing portion 12 The outer surface is convexly provided with a plurality of arranged anti-slip strips 121, and then a cross-shaped connecting portion 13 is connected to the opposite inner side of the first pressing portion 11 and the second pressing portion 12, and the connecting portion 13 has a first elasticity The arm has a bending portion 14, and each bending portion 14 penetrates through a hole 141 transversely, and a turning portion 15 is formed at the connection between the first pressing portion 11 and the second pressing portion 12 on both sides of the second elastic arm 132 , and a hollow hole 151 transversely penetrates each turning portion 15 .

Please refer to Figures 3, 4, 5 and 6, which are the schematic diagrams before pressing, the schematic diagram during pressing, the side view sectional view after pressing, and the schematic diagram after pressing of the present utility model. When pressing the convex strip 111 of the first pressing part 11 of the main body 1 and the anti-slip strip 121 of the second pressing part 12, the first elastic arm 131 and the second elastic arm 132 of the cross-shaped connecting part 13 are elastically deformed to form a cross-relative displacement. Make the piercing hole 141 of the bending part 14 on both sides of the first elastic arm 131 and the hollow hole 151 of the turning part 15 on both sides of the second elastic arm 132 be in a mutual alignment state, that is, the heads at the two ends of the preset rope 2 can be respectively Through the insertion hole 141 and the hollow hole 151 of the main body 1 , the main body 1 can be moved to a proper position on the rope 2 .

In addition, when the force of pressing the first pressing part 11 and the second pressing part 12 is released, through the elastic restoring force of the first elastic arm 131 and the second elastic arm 132, each insertion hole 141 and each hollow hole 151 are formed. Mutual dislocation state, like this, the rope 2 and each piercing hole 141 and each hollow hole 151 produce the state of tight pinch, form stable, sure positioning effect with this, and can be widely used in adjusting the opening on shoes, bags or clothing The size is narrowed and used, and it can achieve the purpose of firm holding and not easy to slip and loose, and has the purpose of simple structure and cost saving.

The above-mentioned convex strip 111 of the first pressing part 11 and the anti-slip strip 121 of the second pressing part 12 can make the user's fingers not slip during the pressing process, making the pressing action simple and reliable. In addition, the first The elastic arm 131 and the second elastic arm 132 are respectively provided with reinforcement blocks 1311 and 1321 with preset thickness on the upper and lower surfaces near the center, so as to increase the structural strength of the first elastic arm 131 and the second elastic arm 132, and can Avoid repeated pressing of the first pressing portion 11 and the second pressing portion 12 so that the first elastic arm 131 and the second elastic arm 132 are close to the center, which may be deformed due to stress concentration, so as to increase the durability.
