Description

Single rope tail buckle

The present invention provides a single rope tail buckle, in particular, the elastic positioning member has a spring arm extending from the opposite end of the elastic end of the bottom surface of the cover body, and the two elastic arms are engaged with the plurality of rods of the opposite inner side wall. The abutting protrusions of the two elastic arms on the opposite side are pushed against the tapered surface of the docking seat passage, and the tension is tightened when the rope is displaced downward, so as to increase the tensile force that can be withstood to avoid slipping.

According to the current use of buckles, the use of buckles is very common, and different types of buckles have different fastening methods, and multiple fasteners can be applied to backpacks, shoes, garments or other available ropes at the same time. The item is used on the item. However, the buckle is usually worn in the cord by the cord, and the head of the two ends of the cord can be worn out, and then inserted through the second head through a buckle so that the buckle can be along the rope. The surface is moved to adjust the size of the opening on the item such as a backpack, shoe body or garment.

In addition, the zipper head piece of the general item or the tail end buckle used at the end of the rope is mostly fixed by a rope with a hollow cylindrical wood product or a plastic piece, and the two ends of the rope must be worn first. Out of the hollow passage in the wood or plastic parts, and a knot as a structure to block the positioning, the rope can be prevented from coming out, but the knot portion of the method will be exposed on the surface of the article, and it is quite abrupt. And it is not very beautiful, and the user can easily accidentally pull the rope to cause any slippage.

In addition, some manufacturers use the plastic inserting method (Insert Molding) to integrally form the rope tail buckle, which can improve the exposed knot of the rope and easily pull the rope to cause any slip. The situation of taking off occurs, but the method of integrally forming the rope tail buckle and the rope belt will improve the difficulty in designing and manufacturing the mold, and the required materials and manufacturing costs are relatively high, and when the rope tail buckle is used, if it is on the article When the weight of the load is heavy or the force is large, the rope tail buckle cannot be reliably and firmly pulled and there is still slippage.

Therefore, if it is possible to design a change in the design of the detachable rope tail buckle structure and improve the effect of the combination of the rope and the positioning of the rope, it is the direction for those who are engaged in this industry to research and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, evaluated and considered them through multiple parties, and through years of experience in the industry, through continuous trial and modification, they have designed such single rope tail buckles. The birth of the creation patent.

The main purpose of the creation is to insert one end of the rope from the lower opening of the channel of the docking seat into the accommodating space between the two elastic arms of the elastic positioning member, and the second elastic arm is to resist the top of the convex block. The pushing surface resists the tapered side of the contact channel, so that the two elastic arms are elastically deformed toward the opposite inner side before the unassembled, so that the plurality of rods on the opposite side of the two elastic arms will bite into the rope to form an urgent positioning, thereby achieving The single rope rope tail buckle is positioned with the rope and is not easily separated.

The second purpose of this creation is that if the rope or the docking seat is pulled and the rope is moved downward, the rope will drive the two elastic arms to move toward the opening under the passage, and the tapered surface of the two sides of the passage. Guide the two arms to push the top surface, and let the two arms move down again. By elastically deforming the displacement toward the opposite side to reduce the distance between the two, the plurality of rods will penetrate the rope deeper, so that when the tension is increased, the two arms will have a larger displacement, and the plurality of rods will be deeper. The bite is inserted into the rope, so the tensile force it can withstand is increased, so as to achieve the effect of tightening and tightening, the slippage can be more reliably avoided.

Another purpose of the present invention is that when the two elastic arms are driven by the rope to move toward the opening under the passage, the base will be displaced downward with the opening and the elastic body will be elastically deformed in the deformation space. When the external force stops, The elastic body will use the elastic restoring force to drive the base to move upwards, and the second arm and the rope will return to the original position, thereby achieving the purpose of shock absorption buffering.

Another purpose of the present invention is that the limit projections at the ends of the two elastic arms are located in the two slides of the docking seat, so when the two elastic arms are displaced, the limit projections are guided through the linear slides. The linear reciprocating displacement is performed so that the two elastic arms do not yaw and twist, so the two elastic arms are only displaced toward the opposite inner side to change the degree of meshing with the rope, so as to ensure the stable combination of the two elastic arms and the rope. .

A further object of the present invention is that the inner side surface of one of the elastic positioning members has a recess extending from the end toward the base between the two rows of the plurality of rods, and the space through the groove can increase the space for accommodating the deformation of the rope. And the groove reduces the thickness of the elastic arm to elastically deform when the plurality of rods are stressed, so that the elastic arm or the plurality of rods can be prevented from being deformed or damaged by excessive external force, thereby achieving the purpose of increasing the service life of the product.
