Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging, and particularly relates to a structure of a packing rope. Background Art
[0002] In the fields of logistics transportation, warehousing packaging, etc., the bundling method of using a packing rope in combination with a packing buckle is widely applied. For the traditional combination structure of a packing rope and a packing buckle, there are problems of insufficient fixing strength and easy loosening. For example, after the metal packing buckle is extruded and deformed, the friction force with the packing rope is limited. When subjected to external forces such as vibration and extrusion during transportation, the packing rope is prone to displacement or even falling off. At the same time, some packing buckle structures lack auxiliary design during the deformation process, resulting in uneven deformation and affecting the fixing effect. In addition, the existing biting method between the end of the packing rope and the packing buckle is single, and it is difficult to achieve tight fixing, unable to meet the packaging requirements of heavy goods or goods for long-term storage.
[0003] Therefore, it is very necessary to invent a structure of a packing rope. Content of the Utility Model
[0004] To solve the above technical problems, the utility model provides a structure of a packing rope, which includes a packing rope, a pulling rope, biting teeth, a packing buckle, pointed protrusions, a partition board, a collapse hole, and a buckle arm. The end of the packing rope is integrally provided with a pulling rope and biting teeth, and the end of the packing rope passes through the packing buckle; pointed protrusions are evenly distributed on the inner wall of the packing buckle, a partition board is arranged in the middle of both ends of the packing buckle, a collapse hole is penetrated and provided on each partition board, and a buckle arm is arranged.
[0005] Preferably, the end face of the packing rope is integrally provided with an annular pulling rope, and the side of its end is integrally provided with protruding biting teeth, and several of the biting teeth are arranged horizontally along the axis of the packing rope.
[0006] Preferably, the end of the packing rope can pass through the inner area of the packing buckle, and the inside of the packing buckle is divided by two unconnected partition boards, forming a structure like the Chinese character 'Ri' (日).
[0007] Preferably, an inclined buckle arm is arranged in the middle of each partition board, the buckle arm is an inclined 'L'-shaped structure, and the included angle of the buckle arm can bite with the biting teeth at the end of the pulling rope.
[0008] Preferably, several collapse holes are horizontally penetrated and arranged on each partition board in the packing buckle, the collapse holes are arc-shaped through holes, and the collapse holes can assist the partition board to generate deformation.
[0009] Preferably, the pointed protrusions provided on the inner wall of the packing buckle are in the shape of conical protrusions, and their pointed ends can contact the surface of the drawstring. The packing buckle can be deformed inwardly by the compression of the packing pliers, and the pointed protrusions provided on its inner wall can pierce into the drawstring.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] By providing bite teeth at the end of the packing rope and cooperating with the pointed protrusions on the inner wall of the packing buckle, when the packing buckle is compressed by the packing pliers to generate deformation, the pointed protrusions pierce the drawstring, and the bite teeth bite with the buckle arm, forming a multiple mechanical locking structure, significantly enhancing the friction and tensile resistance between the packing rope and the packing buckle, effectively preventing loosening or falling off during transportation, and ensuring firm bundling of goods.
[0012] The collapse holes provided on the inner partition of the packing buckle of the utility model can assist the partition to generate uniform deformation when受力, reduce the requirement for the pressure accuracy of the packing pliers, make the packing buckle more likely to undergo the ideal inward concave deformation, and improve the packing efficiency and structural reliability.

[0021] As attached Figure 1 To be continued Figure 3 As shown:
[0022] This utility model provides a packing rope structure, including a packing rope 1, a pull rope 2, teeth 3, a packing buckle 4, pointed protrusions 5, partitions 6, collapse holes 7, and buckle arms 8. The end of the packing rope 1 is integrally provided with the pull rope 2 and the teeth 3, and the end of the packing rope 1 passes through the packing buckle 4. The inner wall of the packing buckle 4 is evenly distributed with pointed protrusions 5, and a partition 6 is provided in the middle of both ends. Each partition 6 is provided with a collapse hole 7 and a buckle arm 8.
[0023] Furthermore, the packing rope 1 is made of high-strength polypropylene material, and its end face is integrally molded into a ring-shaped pull rope 2 through injection molding. The pull rope 2 is easy to hook and pull with fingers; the side of the end of the packing rope 1 is also formed with raised teeth 3 through injection molding. The teeth 3 have a trapezoidal cross section, with an adjacent tooth spacing of 3mm, and are equidistantly arranged laterally along the axis of the packing rope 1. The surface of the teeth 3 is provided with anti-slip texture to enhance the engagement friction with the buckle arm 8.
[0024] Furthermore, the packing buckle 4 is made of industrial-grade galvanized steel sheet by stamping and is flat overall. It is divided by two parallel and non-connected partitions 6 inside to form a "day" - shaped hollow structure. The partition 6 has a thickness of 2 mm and a spacing of 10 mm, which can accommodate packing ropes 1 of different specifications to pass through. The edges at both ends of the packing buckle 4 are designed as rounded corners to avoid scratching the operator and the packaged goods.
[0025] Furthermore, an inclined buckle arm 8 is formed in the middle of each partition 6 by stamping. The buckle arm 8 has an "L" - shaped structure and an inclined angle of 45°. A reinforcing rib is provided at the connection between the buckle arm 8 and the partition 6 to enhance the structural strength. A groove matching the shape of the bite teeth 3 is provided inside the included angle of the buckle arm 8. When the packing buckle 4 is not deformed by pressure, the buckle arm 8 and the bite teeth 3 are tightly engaged to achieve mechanical locking.
[0026] Furthermore, 5 arc-shaped collapse holes 7 are horizontally drilled through each partition 6. The collapse holes 7 have a diameter of 3 mm and a central angle of 120°. The collapse holes 7 are symmetrically distributed along the center line of the partition 6, and the hole spacing is 5 mm. The arc-shaped design of the collapse holes 7 can guide the partition 6 to produce uniform deformation along the preset direction when the packing buckle 4 is under pressure, reducing the required pressure value and making the packing operation more labor-saving.
[0027] Furthermore, 12 pointed protrusions 5 are evenly distributed on the inner wall of the packing buckle 4. The pointed protrusions 5 adopt a conical structure with a cone angle of 30° and a tip height of 0.8 mm. The pointed protrusions 5 are integrally formed on the inner wall of the packing buckle 4 by die stamping, and the material is the same as that of the packing buckle 4. When the packing pliers apply pressure to the packing buckle 4 to make it sink inward, the pointed protrusions 5 can pierce the surface of the draw rope 2 and embed about 0.5 mm into the draw rope 2, further enhancing the friction force and the fixing effect.
[0028] The working principle is as follows: First, after surrounding the item to be tied with the packing rope 1, the part with the draw rope 2 and the bite teeth 3 at the end is passed through the "day" - shaped hollow structure of the packing buckle 4. At this time, the bite teeth 3 are in preliminary contact with the buckle arm 8. Then, the packing pliers apply pressure to the packing buckle 4. Under the action of the pressure, the packing buckle 4 sinks inward, and the two side partitions 因溃缩孔7的引导,产生均匀的塑性形变,在此过程中,打包扣4内壁的尖凸5随着打包扣4的凹陷刺入拉绳2表面,进一步增加摩擦力;最后,打包钳持续施压直至打包扣4完全变形固定,完成打包绳1与物品的牢固捆绑,拉绳2可用于后续调整松紧或辅助拆卸。
