Description

Technical Field

[0001] The utility model relates to a traction rope, in particular to a traction rope with a wear-resistant structure, belonging to the technical field of traction ropes. Background Art

[0002] A car towing rope is mainly used to connect two cars, using the traction of one car to tow another car that cannot move on its own. It is widely used in many occasions such as road rescue, off-road adventures, and racing events. It is an indispensable part of car emergency equipment. The specifications of a car towing rope usually include parameters such as length, diameter, and load-bearing capacity. When choosing, you need to determine the appropriate specifications based on the specific usage scenario and needs.

[0003] In the prior art, for example, a wear-resistant automobile traction rope disclosed in announcement number CN204109710U uses a steel wire spring to separate the rope fibers from the road surface by a certain distance, thereby forming isolation protection for the rope, effectively preventing the damage of road debris and oil stains to the rope, and reducing the influence of high road temperature on the strength performance of high-strength and high-modulus polyethylene fiber materials, thus adapting well to harsh working environments such as road traction.

[0004] However, in actual use, during the use of the above-mentioned wear-resistant automobile towing rope, the rope fibers are mainly separated from the road surface by the steel wire springs by a distance, thereby isolating and protecting the rope to prevent it from being affected by small debris and oil stains on the road surface. However, during the towing of the car, the rope will be pulled to a certain extent, so that the length of the rope will change. When the rope is stretched, the steel wire spring will also be stretched accordingly. At this time, a certain gap will be generated between the steel wire springs due to the stretching. When the steel wire springs have a certain gap, their isolation effect on the rope fibers will be reduced, and external stones or some impurities can easily pass through the steel wire springs to cause certain wear on the towing rope. Utility Model Content

[0005] The utility model solves the problem that in the process of using the above-mentioned wear-resistant automobile traction rope, the rope fibers are mainly separated from the road surface by a distance through the steel wire spring, so as to form isolation protection for the rope and prevent it from being affected by fine debris and oil pollution on the road surface. However, in the process of towing the car, the rope will produce a certain pulling, so that the length of the rope will change. When the rope is stretched, the steel wire spring will also be stretched accordingly. At this time, a certain gap will be generated between the steel wire springs due to the stretching. When the steel wire spring has a certain gap, its isolation effect on the rope fibers will be reduced, and external stones or some impurities can easily pass through the steel wire spring to cause certain wear on the traction rope. Therefore, a traction rope with a wear-resistant structure is provided.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a traction rope with a wear-resistant structure, comprising a hook body, a threaded rod fixedly installed below the hook body and a fixed body threadedly installed outside the threaded rod, an extension component is arranged inside the fixed body, and a rope body is inserted below the extension component;

[0007] The rope body includes a rope core, a protective cover is provided on the outer side of the rope core, the protective cover includes an inner layer, an inner layer is provided on the outer side of the inner layer, and an outer layer is provided on the outer side of the inner layer, one group of the protective covers is located on the outer side of the rope core and multiple groups of elastic connecting ropes are fixedly installed, and one end of the elastic connecting rope passes through another multiple groups of protective covers.

[0008] As a further solution of the utility model: the inner layer and the rope core are both made of polyester fiber materials, the inner layer is a ring body woven from steel wires, and the outer layer is made of high molecular polyethylene material.

[0009] As a further solution of the utility model: a socket matching the elastic connecting rope is provided at the connection between the protective sleeve and the elastic connecting rope, and the socket is provided on the protective sleeve.

[0010] As a further solution of the utility model: the extension component includes an insertion rod, a mounting tube is fixedly installed below the insertion rod, and a spring rod is arranged on the outside of the insertion rod located inside the fixed body, and the spring rod is arranged on both sides of the insertion rod.

[0011] As a further solution of the utility model: a plurality of positioning holes matching with the elastic pressure rods are provided at the connection between the fixed body and the elastic pressure rods, and the positioning holes are provided on the surface of the fixed body.

[0012] As a further solution of the utility model: a positioning rod is fixedly installed on the top end surface inside the fixed body, a tension spring is sleeved on the outer side of the positioning rod, and the other end of the tension spring is fixedly installed on the top end surface of the insertion rod.

[0013] As a further solution of the utility model: a fixing screw is inserted at the connection between the mounting tube and the rope body, one end of the fixing screw passes through the rope body, and one end of the fixing screw extends to the other end of the mounting tube, and the fixing screw is located on the outer side of the mounting tube and is threadedly installed with a limiting nut.

[0014] The beneficial effects of the utility model are:

[0015] The rope core is protected by the protective cover. When the rope core is pulled, there will be a certain gap between the protective covers. However, multiple elastic connecting ropes are provided at the connection between the protective cover and the rope core. The elastic connecting ropes wrap the rope core, thereby protecting the rope core after the rope core is pulled. During the use of the rope, the outer and inner layers of the protective cover can achieve the wear resistance of the rope body itself after the rope body is rubbed from the ground.

[0016] By setting up the extension component, it is possible to manually press the two groups of spring rods before installing the rope body so that the spring rods are disengaged from one group of positioning holes, and pull or push the insertion rod as needed so that the spring rods are elastically clamped in other positioning holes, thereby achieving length adjustment between the insertion rod, the installation tube and the fixed body, making it easier for the traction rope to be used in the traction of different vehicles.

[0027] The extension component 4 includes an insertion rod 401, a mounting tube 402 is fixedly installed below the insertion rod 401, and a spring rod 403 is arranged on the outside of the insertion rod 401 located inside the fixed body 3, and the spring rod 403 is arranged on both sides of the insertion rod 401. A plurality of positioning holes 13 matching the spring rod 403 are provided at the connection between the fixed body 3 and the spring rod 403. The positioning holes 13 are provided on the surface of the fixed body 3, and a positioning rod 14 is fixedly installed on the top surface of the fixed body 3. A tension spring 15 is sleeved on the outside of the positioning rod 14, and the other end of the tension spring 15 is fixedly installed on the top surface of the insertion rod 401. The mounting tube 402 is connected to the rope body. 5 is inserted with a fixing bolt, one end of the fixing screw penetrates the aluminum alloy sleeve at one end of the rope body 5, and one end of the fixing screw extends to the other end of the mounting tube 402, the fixing screw is located on the outer side of the mounting tube 402 and a limit nut is installed on the threaded installation.
