Description

Technical Field

[0001] The present application relates to the technical field of electric wires and cables, and in particular to a retractable sliding wire harness structure. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection of the following parts; one or more insulated cores, and their respective coatings, total protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] In the prior art, wires and cables are usually designed with fixed lengths, which limits their flexibility in use in many situations. At present, in order to solve the problem of fixed lengths of wires and cables, some manufacturers have launched retractable wire and cable products. These products usually use a spiral structure or a spring structure to achieve the retractable function. The existing retractable wires and cables have problems such as complex structure, high manufacturing cost, limited retractable performance and short service life. Therefore, a retractable sliding wire structure is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a retractable sliding wire harness structure, which has the advantage of good retractable effect and solves the problems of existing retractable wires and cables, such as complex structure, high manufacturing cost, limited retractable performance and short service life.

[0005] In summary, the present application provides the following technical solutions: a retractable sliding beam wire structure, comprising an inner core body and an outer protective sleeve arranged outside the inner core body, wherein a sliding beam structure is arranged between the inner core body and the outer protective sleeve;

[0006] The sliding beam structure includes a sliding ring slidably connected between the inner core body and the outer protective sleeve. The number of the sliding rings is five. The five sliding rings are sleeved with each other, and the inner wall of the sliding ring fits with the outer side of the inner core body.

[0007] The present application adopts the above-mentioned technical solution and sets five sliding rings to realize the telescopic function of the sliding beam structure, so that the inner core body can be smoother and more stable when telescoped. By setting limit blocks and limit grooves, the sliding ring can be limited so that it can only slide in the direction of the inner core body. At the same time, since the inner wall of the sliding ring fits with the outer wall of the inner core body, the stability of the sliding ring movement can be improved, and the strength of the inner core body when telescoped can be improved.

[0008] Furthermore, a limiting block extending to the inside of the other sliding ring is fixedly connected to the outer wall of one of the sliding rings, and a limiting groove matched with the limiting block is formed on the inner wall of the sliding ring.

[0009] The beneficial effect of adopting the above further solution is that by providing the limiting block and the limiting groove, the sliding ring can be limited so that it can only slide in the direction of the inner core body.

[0010] Furthermore, the sliding ring is a hollow cylinder, the outer wall of the sliding ring is fixedly connected with a guide block extending into the inner part of the outer protective sleeve, and the inner wall of the outer protective sleeve is provided with a guide groove matched with the guide block.

[0011] The beneficial effect of adopting the above further solution is that by providing the guide block and the guide groove, the sliding ring can be prevented from rotating on the inner wall of the outer protective sleeve, and the sliding ring can be limited, thereby improving the telescopic stability of the sliding beam structure.

[0012] Furthermore, the sliding ring is a hollow cylinder, and the inner wall of one sliding ring fits with the outer wall of another sliding ring.

[0013] The beneficial effect of adopting the above further solution is that the overall strength of the sliding beam structure can be improved by fitting the inner and outer walls of the two sliding rings together.

[0014] Furthermore, a wear-resistant layer is provided on the inner wall of the outer protective sleeve, and a flame-retardant layer is provided on a side of the outer protective sleeve away from the wear-resistant layer.

[0015] The beneficial effect of adopting the above further solution is that by providing the wear-resistant layer, the degree of wear of the sliding ring on the inner wall of the outer protective sleeve can be reduced.

[0016] Furthermore, a corrosion-resistant layer is provided on a side of the flame-retardant layer away from the outer protective cover, and a waterproof layer is provided on a side of the corrosion-resistant layer away from the flame-retardant layer.

[0017] The beneficial effect of adopting the above further scheme is: by providing a flame retardant layer, a corrosion resistant layer and a waterproof layer, the protective performance of the outer protective cover can be improved, while the service life of the inner core body is increased, and the resistance of the outer protective cover to external environmental factors is enhanced.

[0018] Compared with the prior art, the present application provides a retractable sliding cable structure, which has the following beneficial effects:

[0019] 1. The retractable sliding beam structure can realize the retractable function of the sliding beam structure by setting five sliding rings, so that the inner core body can be smoother and more stable when retracting. The sliding ring can be limited by setting a limit block and a limit groove so that it can only slide in the direction of the inner core body. At the same time, since the inner wall of the sliding ring fits the outer wall of the inner core body, the stability of the sliding ring movement can be improved, and the strength of the inner core body when retracting can be improved. At the same time, the manufacturing method of the structure is simple and easy, and is suitable for large-scale production.

[0020] 2. The retractable sliding wire harness structure can reduce the degree of wear of the sliding ring on the inner wall of the outer protective cover by providing a wear-resistant layer, and can improve the protective performance of the outer protective cover by providing a flame retardant layer, a corrosion-resistant layer and a waterproof layer. At the same time, the service life of the inner core body is increased, and the resistance of the outer protective cover to external environmental factors is enhanced, thereby solving the problems of complex structure, high manufacturing cost, limited retractable performance and short service life of existing retractable wires and cables.

[0026] See also Figure 1-2 A retractable sliding beam wire structure in this embodiment includes an inner core body 1 and an outer protective cover 2 arranged outside the inner core body 1. The inner core body 1 is formed by twisting multiple wires and is used to transmit electrical energy or signals. A sliding beam structure 3 is arranged between the inner core body 1 and the outer protective cover 2. The sliding beam structure 3 includes a sliding ring 4 slidably connected between the inner core body 1 and the outer protective cover 2. The number of the sliding rings 4 is five, and the five sliding rings 4 are mutually socketed. The inner wall of the sliding ring 4 fits with the outside of the inner core body 1.

[0027] Among them, a limit block 5 extending to the inside of another sliding ring 4 is fixedly connected to the outer wall of one sliding ring 4, and a limit groove matched with the limit block 5 is opened on the inner wall of the sliding ring 4. The sliding ring 4 is a hollow cylinder. The outer wall of the sliding ring 4 is fixedly connected to a guide block 6 extending to the inside of the outer protective sleeve 2, and a guide groove matched with the guide block 6 is opened on the inner wall of the outer protective sleeve 2. By setting five sliding rings 4, the telescopic function of the sliding beam structure 3 can be realized, so that the inner core body 1 can be smoother and more stable when telescoping, and then by setting the limit block 5 and the limit groove, the sliding ring 4 can be limited so that it can only slide in the direction of the inner core body 1.

[0028] It should be noted that the sliding ring 4 is a hollow cylinder, in which the inner wall of one sliding ring 4 fits with the outer wall of another sliding ring 4, and the sliding ring 4 is made of rubber. During the production process, the staff can set up multiple sliding rings 4 to form a longer sliding beam structure 3. The critical length of the sliding beam structure 3 can also be adjusted by changing the number of sliding rings 4, thereby improving the practicability of the device.

[0029] See also Figure 1 and Figure 3 In this embodiment, a wear-resistant layer 7 is provided on the inner wall of the outer protective cover 2, a flame-retardant layer 8 is provided on the side of the outer protective cover 2 away from the wear-resistant layer 7, a corrosion-resistant layer 9 is provided on the side of the flame-retardant layer 8 away from the outer protective cover 2, and a waterproof layer 10 is provided on the side of the corrosion-resistant layer 9 away from the flame-retardant layer 8.

[0030] Among them, the material of the wear-resistant layer 7 is epoxy resin, which is a high-performance coating with high surface hardness, good wear resistance and strong chemical corrosion resistance. The material of the corrosion-resistant layer 9 is anti-corrosion coating, which can ensure that the outer protective cover 2 is buried underground for a long time without being corroded.

[0031] It should be noted that by providing the wear-resistant layer 7, the degree of wear of the sliding ring 4 on the inner wall of the outer protective cover 2 can be reduced, and by providing the flame retardant layer 8, the corrosion-resistant layer 9 and the waterproof layer 10, the protective performance of the outer protective cover 2 can be improved, and at the same time, the service life of the inner core body 1 can be improved, and the resistance of the outer protective cover 2 to external environmental factors can be enhanced.

[0032] The working principle of the above embodiment is:

[0033] First, the staff puts the slide beam structure 3 on the surface of the inner core body 1, and then puts the outer protective cover 2 on the surface of the slide beam structure 3. At this time, the guide block 6 on the surface of the slide ring 4 fits with the guide groove on the inner wall of the outer protective cover 2. At this time, the slide ring 4 can slide inside the outer protective cover 2. After that, the staff retracts and extends the slide beam structure 3 to connect the inner core body 1 between the two electrical components. When the staff pulls the inner core body 1, the slide beam structure 3 can retract and extend.
