Description

Technical Field

[0001] This utility model relates to the field of cable external wear protection technology, and in particular to a cable external wear protection device. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of wires. In construction sites, cables are often used to transmit power to electric drills. However, when an electric drill is working at different construction sites, it is necessary to frequently move the drill and the cable connected to it.

[0003] Existing electric drill cables are usually equipped with rubber protective sleeves, which fit tightly against the cable sheath, allowing the electric drill cable to withstand a certain degree of friction and effectively preventing wear on the cable sheath.

[0004] However, when an electric drill frequently moves and connects cables, it can easily bend the cables, causing stress concentration at the bends. This can lead to severe wear and tear on the cables, thus affecting their lifespan. Utility Model Content

[0005] Therefore, it is necessary to provide an external cable wear protection device to address the problem that electric drills frequently bend the connected cables, causing stress concentration at the bends and leading to severe cable wear.

[0006] The cable includes: a sheath, with a reinforcing layer fixedly connected to its inner wall, and an insulating layer fixedly connected to the inner wall of the reinforcing layer, the insulating layer containing annularly distributed cable cores; and an anti-abrasion mechanism, comprising reinforcing rings fixedly connected to the surface of the reinforcing layer in equal rows, with annularly distributed buffer pads fixedly connected to one end of each reinforcing ring. The interaction between the reinforcing rings and the buffer pads improves the overall toughness of the sheath, preventing severe wear on the cable due to frequent bending, ensuring the sheath's abrasion resistance, and thus guaranteeing the cable's service life.

[0007] In one embodiment, the inner wall of the reinforcing layer is fixedly connected with annularly distributed elastic rods, the surfaces of which are fixedly connected to the inner wall of the insulation layer. These elastic rods improve the overall toughness of the cable, ensuring its overall bending resistance and reducing external wear, thereby guaranteeing the cable's service life.

[0008] In one embodiment, the inner wall of the insulation layer is fixedly connected to an annularly distributed flame-retardant sleeve, and the surface of the cable core is fixedly connected to the inner wall of the flame-retardant sleeve.

[0009] In one embodiment, a ring-shaped set of fixing pads is fixedly connected to the surface of the flame-retardant sleeve, and the surface of the fixing pads is fixedly connected to the inner wall of the insulation layer. The interaction between the flame-retardant sleeve and the fixing pads enhances the impact resistance of the cable core, reducing the probability of damage to the cable core during bending.

[0010] In one embodiment, a support rod is fixedly connected to the inner wall of the insulating layer.

[0011] In one embodiment, a ring of elastic pads is fixedly connected to the surface of the support rod, and the surface of the elastic pads is fixedly connected to the inner wall of the insulation layer. Through the interaction between the support rod and the elastic pads, the overall toughness of the cable core is improved, ensuring the cable core's bending resistance and thus guaranteeing its service life.

[0012] In one embodiment, the surfaces of the buffer pad, the elastic rod, and the elastic pad are all corrugated.

[0013] Beneficial effects

[0014] 1. By combining the reinforcing ring and the buffer pad, the overall toughness of the sheath is improved, which avoids severe wear of the cable due to frequent bending, ensures the wear resistance of the sheath, and thus ensures the service life of the cable.

[0015] 2. The elastic rod improves the overall toughness of the cable, ensuring its overall bending resistance and reducing external wear, thereby extending its service life. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined with Figures 1-5 This invention describes a cable external abrasion protection device.

[0026] In one embodiment, a cable external abrasion protection device includes: a sheath 100, a reinforcing layer 200 fixedly connected to the inner wall of the sheath 100, an insulating layer 300 fixedly connected to the inner wall of the reinforcing layer 200, and a cable core 400 arranged in a ring inside the insulating layer 300; and an anti-abrasion mechanism 500, which includes reinforcing rings 501 fixedly connected to the surface of the reinforcing layer 200 and evenly distributed, with a ring-shaped buffer pad 502 fixedly connected to one end of each reinforcing ring 501.

[0027] It should be noted that the sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502 are all polyurethane rubber components, which have extremely high wear resistance. When the electric drill is used, it drags the cable, causing the cable to come into contact with the ground or objects. The sheath 100 can effectively resist these frictions, greatly extending the service life of the cable and reducing the frequency of cable damage and replacement due to wear.

[0028] The polyurethane rubber components, including the sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502, possess excellent elasticity and flexibility, allowing for easy bending and twisting without breakage or damage. The sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502 ensure that the cable can bend freely in various complex working environments and quickly return to its original shape after bending, ensuring that the internal structure of the cable is not damaged and maintaining the normal performance of the cable.

[0029] The sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502 of the polyurethane rubber component have high tear resistance. When subjected to external tearing force, the sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502 can withstand a large force without being torn.

[0030] The polyurethane rubber components, including the sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502, possess advantages such as oil resistance, chemical resistance, good insulation performance, and light weight. These components also exhibit good anti-aging properties, resisting the effects of ultraviolet radiation, ozone, and heat-oxidizing agents, thus slowing down the aging process of the sheath 100, insulation layer 300, reinforcing ring 501, and buffer pad 502. For cables used in outdoor environments like electric drills, which are exposed to sunlight and air for extended periods, the polyurethane rubber sheath 100 effectively prevents cracking and hardening caused by aging, ensuring the cable's service life.

[0031] The reinforcing layer 200 is a steel wire component, possessing high strength and good flexibility, providing strong support when the cable is subjected to external forces such as bending and tension. The steel wire reinforcing layer 200 has a high modulus of elasticity, effectively dispersing stress during cable bending and preventing damage to the cable's internal structure due to excessive stress.

[0032] In this embodiment, when the electric drill needs to move the cable frequently during operation, causing the cable to bend, the sheath 100 first comes into contact with the ground or object. The sheath 100 of the polyurethane rubber component, the insulation layer 300, the reinforcing ring 501, the buffer pad 502, and the reinforcing layer 200 of the steel wire component can effectively resist these friction and bending forces, ensuring the wear resistance of the cable exterior.

[0033] like Figure 4 As shown, the inner wall of the reinforcing layer 200 is fixedly connected with annularly distributed elastic rods 503, the surface of the elastic rods 503 is fixedly connected to the inner wall of the insulation layer 300, the inner wall of the insulation layer 300 is fixedly connected with annularly distributed flame-retardant sleeves 506, the surface of the cable core 400 is fixedly connected to the inner wall of the flame-retardant sleeves 506, the surface of the flame-retardant sleeves 506 is fixedly connected with annularly distributed fixing pads 507, and the surface of the fixing pads 507 is fixedly connected to the inner wall of the insulation layer 300.

[0034] It should be noted that both the flame-retardant sleeve 506 and the fixing pad 507 are polyvinyl chloride components, which have good flame retardancy. Because the flame-retardant sleeve 506 and the fixing pad 507 of the polyvinyl chloride components contain chlorine, they will produce hydrogen chloride gas when burning. This gas can dilute the oxygen in the air, thereby inhibiting the spread of flame and playing a flame-retardant role.

[0035] The flame-retardant sleeve 506 and fixing pad 507 of the PVC components have certain strength and toughness, which can protect the cable core 400 inside the cable from external mechanical damage, and can resist a certain degree of compression, stretching and friction, ensuring the safety of the cable during normal use and installation.

[0036] like Figure 4 As shown, a support rod 504 is fixedly connected to the inner wall of the insulation layer 300, and annularly distributed elastic pads 505 are fixedly connected to the surface of the support rod 504. The surface of the elastic pads 505 is fixedly connected to the inner wall of the insulation layer 300. The surfaces of the buffer pad 502, the elastic rod 503 and the elastic pad 505 are all corrugated.

[0037] It should be noted that the elastic rod 503, support rod 504, and elastic pad 505 are all silicone rubber components, which have excellent high-temperature resistance and can be used for a long time in high-temperature environments without aging or damage. At the same time, the silicone rubber components 503, 504, and 505 also have certain flame-retardant properties, providing some fire protection in the event of a fire.

[0038] The elastic rods 503, support rods 504, and elastic pads 505 of the silicone rubber components have good flexibility, allowing them to bend and twist without damage. They are suitable for cables that require frequent movement or bending. The elastic rods 503, support rods 504, and elastic pads 505 of the silicone rubber components also have excellent weather resistance, resisting the effects of ultraviolet rays, ozone, and climate change, ensuring that the cable can stably transmit electrical energy when the electric drill is used in an outdoor environment.

[0039] Working principle: When the electric drill is in operation, the cable needs to be moved frequently, causing the cable to bend. The sheath 100 first comes into contact with the ground or object. Because the polyurethane rubber components sheath 100, insulation layer 300, reinforcing ring 501 and buffer pad 502, steel wire reinforcing layer 200, polyvinyl chloride flame retardant sleeve 506 and fixing pad 507, and silicone rubber components elastic rod 503, support rod 504 and elastic pad 505 all have good flexibility and wear resistance, they can effectively resist the friction and bending force generated by the cable during movement, ensuring the wear resistance of the cable exterior and avoiding severe wear on the cable exterior.

[0040] It should be noted that the sheath 100, reinforcing layer 200, insulation layer 300 and cable core 400 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
