Description

Technical Field

[0001] The utility model relates to the technical field of drawstrings, in particular to a mildew-proof drawstring. Background Art

[0002] A pull rope is usually a rope used to pull, move or secure an object. This type of rope is widely used in many fields such as daily life, industrial production, transportation, outdoor sports, etc. They are usually made of high-strength materials such as nylon, polyester, linen, cotton or wire, which give the rope the necessary strength and durability to withstand the forces generated during the pulling process.

[0003] When the pull rope is used to transmit force, especially when it is driven by manpower, the manpower will hold one end of the pull rope to exert force, thereby pulling the object at the other end of the pull rope. However, when the human hand directly touches one end of the pull rope, the contact area is small, so the pull rope will exert a large pressure on the human hand when it touches, and the human hand will feel pain. At the same time, this is not convenient for transmitting force to the pull rope.

[0004] Therefore, a mildew-proof drawstring is proposed to solve or alleviate the above problems. Utility Model Content

[0007] A mildew-proof pull rope comprises a rope body and a pull rod, wherein the rope body comprises a plurality of inner threads and an outer layer fixedly connected to the outer side thereof, and the pull rod comprises two halves of detachably connected connecting shells, wherein the two halves of the connecting shells clamp the outer layer and the plurality of inner threads at the ends of the rope body.

[0008] Preferably, one end of the two halves of the connecting shell is hinged, and the two halves of the connecting shell are detachably connected to each other at one end away from the hinge, and the end of the rope body is arranged to pass through the hinge of the connecting shell.

[0009] Preferably, the connecting shell includes a cylindrical portion with a semicircular cross-section, an expansion portion fixedly connected to the cylindrical portion, and a U-shaped handle portion fixedly connected to the expansion portion, a plurality of spaced-apart clips 1 are fixedly connected inside the cylindrical portion, a plurality of spaced-apart clips 2 are fixedly connected inside the expansion portion, the first clip clamps the outer layer, and the second clip clamps the inner thread.

[0010] Preferably, the inner filament is formed by twisting two strands of yarn.

[0011] Preferably, the ply yarn comprises a plurality of twisted polypropylene fibers and a plurality of acrylic fibers parallel to the outer rings of the plurality of polypropylene fibers, and the ply yarn is self-twisted.

[0012] Preferably, the outer layer is formed by winding an outer wire around the outer sides of a plurality of inner wires.

[0013] Preferably, the outer filaments include a plurality of hollow cotton yarns arranged in parallel, and a plurality of polyester fibers wound around the outer sides of the plurality of hollow cotton yarns in the same direction.

[0014] The utility model has the following beneficial effects:

[0015] The utility model fixes the outer layer and a plurality of inner threads at the end of the rope body by a pull rod. In this way, when the pull rope needs to be pulled by the user, there is no need to directly contact the rope body with the palm of the hand. Instead, the end of the rope body can be clamped by the pull rod, and then the pull rod is held to exert force. Such operation increases the contact area on which the user's palm can exert force, and also avoids direct contact between the rope body and the user's palm to generate a large pressure thereon. In addition, the pull rod remains coaxially arranged with the rope body, so that the force can be more directly transmitted to the rope body, so that the user can provide force for pulling.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] A mildew-proof drawstring, such as Figure 2 As shown, it includes a rope body 1 and a pull rod 2. Figure 3 As shown, the rope body 1 includes a plurality of inner threads 102 and an outer layer 101 fixedly connected to the outside thereof, and the pull rod 2 includes two halves of detachably connected connecting shells, which clamp the outer layer 101 and the plurality of inner threads 102 at the ends of the rope body 1.

[0024] like Figure 1 and 2 As shown, one end of the two-part connecting shell is hinged, and the two-part connecting shell is detachably connected to each other at the end away from the hinge. The end of the rope body 1 is arranged to pass through the hinge of the connecting shell. Specifically, one end of the two-part connecting shell is fixedly connected to a cylindrical rotating drum, and the other end is fixedly connected to a rotating shaft rotatably connected to the rotating drum, thereby realizing the hinge between the two.

[0025] The connecting shell formed by plastic injection molding includes a cylinder 201 with a semicircular cross-section, an expansion portion 202 fixedly connected to the cylinder 201, and a U-shaped handle portion 203 fixedly connected to the expansion portion 202, the expansion portion 202 has a trapezoidal cross-section, and all three are hollow, and an insert is fixedly connected to the handle portion 203 in one petal of the connecting shell, and the insert can be embedded in the hollow recess of the handle portion 203, and the detachable connection between the two is completed by the plug-in method, and a plurality of spaced-apart clips 1 204 are fixedly connected to the cylinder 201, and a plurality of spaced-apart clips 2 205 are fixedly connected to the expansion portion 202, the clip 1 204 clamps the outer layer 101, and the clip 2 205 clamps the inner thread 102.

[0026] like Figure 4 As shown, the inner wire 102 is formed by twisting two strands 1021, the strands 1021 include a plurality of twisted polypropylene fibers 10211, and a plurality of acrylic fibers 10212 parallel to the outer rings of the plurality of polypropylene fibers 10211, the acrylic fibers 10212 have the advantage of strong mildew resistance, making the rope body 1 less likely to break, and the strands 1021 are self-twisted. Figure 5 As shown, the outer layer 101 is formed by winding outer threads around the outer sides of a plurality of inner threads 102 , and the outer threads include a plurality of hollow cotton yarns 1011 arranged in parallel, and a plurality of polyester fibers 1012 wound around the outer sides of the plurality of hollow cotton yarns 1011 in the same direction.

[0027] When people need to obtain the rope body 1, they only need to take five polypropylene fibers 10211 to parallel them and use them as the inner circle, and then take more acrylic fibers 10212 and parallel them together with several polypropylene fibers 10211 through a paralleling machine, so that the acrylic fibers 10212 can wrap the several polypropylene fibers 10211 in the inner circle, and then the yarn leaving the paralleling machine is passed through a twisting machine to complete self-twisting, so that people can obtain the yarn strands 1021, and then the two yarn strands 1021 are twisted by a double-strand braiding method to obtain the inner wire 102 that people need.

[0028] When obtaining the outer filament, one only needs to take three hollow cotton yarns 1011, and then take a number of polyester fibers 1012 and use a twisting machine to spirally wind them around the outside of the three hollow cotton yarns 1011 in the same direction to form an outer filament. Finally, take a number of inner filaments 102 and use a covering yarn machine to wind the outer filaments around the outside of the inner filaments 102 to form an outer layer 101, and the rope body 1 can be obtained. It is necessary to ensure that the length of the outer layer 101 is less than the length of the inner filament 102, and part of the outer layer 101 can be peeled off by cutting, so that the two ends of the inner filament 102 are exposed to the two ends of the outer layer 101.

[0029] Such a rope body 1 can properly protect the inner wire 102 through the structure of the outer layer 101, and the inner wire 102 can be fixed by being wrapped around the outer wire, so it is not easy for the outer layer 101 and the inner wire 102 to slip off. When the rope body 1 needs to transmit force, the force can be distributed through a plurality of inner wires 102. The outer layer 101 and the inner wire 102 of the rope body 1 are clamped together by the clamp 1 204, and the clamp 2 205 clamps a plurality of inner wires 102, so that when the pull rod 2 pulls the rope body 1, there can be multiple force points. In addition, when the clamp 1 204 clamps the outer layer 101, it can also clamp a plurality of inner wires 102 therein, so that when the force is transmitted, the rope body 1 bears the force as a whole and is not easy to break.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
