Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a tensile-resistant cable. Background Technology

[0002] As an essential component widely used in power transmission, signal transmission, and other fields, the performance of cables directly affects the stable operation of various systems. Among the many practical applications of cables, tensile strength is an extremely critical indicator.

[0003] Traditional cables have a relatively simple structure, generally consisting only of the cable and its outer sheath. When the cable is subjected to external tension, the tension acts directly on the inner core. Due to the cable's limited tensile strength, this can easily cause the inner core to break, leading to the failure of the entire cable. Furthermore, during installation and use, the cable may detach from its groove, which not only affects its normal operation but may also cause safety accidents.

[0004] To improve the tensile strength of cables, some existing technologies employ the method of incorporating guy wires within the cable. However, these guy wires are typically simply embedded within the cable sheath, with a relatively simple connection method, resulting in limited improvement in the cable's tensile strength. Moreover, existing cable structures cannot effectively release the accumulated length when subjected to tensile force, leading to excessive tensile stress on the cable and still posing a high risk of damage.

[0005] Meanwhile, existing cable fixing methods are not perfect. During installation, it is difficult to flexibly fix the cable at different locations according to the actual situation to adjust the tensile force on the cable. This limits the adaptability and reliability of the cable in different usage scenarios.

[0006] In summary, existing cables have many shortcomings in terms of tensile strength, tension release, and fixation adjustment, failing to meet the safety and reliability requirements of cables in practical applications. Therefore, a new type of tensile-resistant cable is needed to solve these problems. Utility Model Content

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] It should be noted that all components in the technical solution of this application require necessary additional facilities for water supply, oil supply, power supply, and gas supply for driving and / or control. Unless otherwise stated, they are assumed to be used and equipped with existing technology and no special explanation is required.

[0020] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Depend on Figure 1-7 The illustrated tensile cable includes a cable and auxiliary components. The auxiliary components include several retaining rings 3, adjacent retaining rings 3 are fixedly connected by elastic connectors 6. The outer surface of each retaining ring 3 has a spiral groove 4, the edges of which are chamfered to facilitate cable detachment and insertion. Simultaneously, the cable needs to be partially fixedly connected to the spiral groove 4 (by bonding, welding, or using a pressure strip) to facilitate cable retraction and prevent it from slipping out of the groove. The cable is wound within the spiral groove 4; a pull wire 5 is embedded within the cable, and several fixing components are detachably connected to the outside of the cable, spaced apart and used to clamp the pull wire 5.

[0022] Furthermore, the guy wire 5 is made of steel cable, which can be integrally formed with the insulation layer of the outer sheath 2, thereby enhancing the strength of the cable. Also, there can be several guy wires 5, customized according to the actual application. This is existing technology and will not be elaborated further here.

[0023] Further optimizing the design, connector 6 is an elastic tension bar or spring. One end of connector 6 is fixedly connected to end head 7, with a screw hole 18 at its center. End head 7 has a frustum-shaped structure and penetrates one end face of fixing ring 3, fitting into the fixing ring 3. A first screw 8 is screwed into the screw hole 18. Connector 6 can connect the fixing rings 3 at both ends, and the fixing ring 3 in the middle can be fixedly or slidably connected to connector 6, serving to retract the cable into the spiral groove 4 in sections.

[0024] Furthermore, the end faces of the fixing rings 3 located at both ends of the auxiliary component are provided with connecting holes, which are adapted to the end head 7. The end head 7 can be screwed into the first screw 8 through the screw hole 18. The first screw 8 can squeeze the end head 7 against the side walls of the connecting holes on both sides of the fixing rings 3, preventing the connector 6 from falling off when the fixing rings 3 are stretched on both sides, thus preventing the failure of this utility model.

[0025] The design is further optimized by including a first fixing shell 9 and a second fixing shell 10 as the fixing components. The first fixing shell 9 and the second fixing shell 10 are respectively fitted onto the outside of the cable, and the two fixing shells are fixedly connected by a connector. Through the fixed connection of the first fixing shell 9 and the second fixing shell 10, the fixing components can fix the cable at different positions of the spiral according to actual conditions, thereby adjusting the tension on the cable to different degrees.

[0026] In a further optimized design, the connector includes a plug strip 11, one end of which has a groove 12. A first slide bar 13 and a second slide bar 14 are fixedly connected to opposite sides of the plug strip 11. The top surface of the plug strip 11 is fixedly connected to the bottom surface of the first fixed housing 9. The top surface of the second fixed housing 10 has slots 15 at both ends, with first sliding grooves 16 and second sliding grooves 17 on opposite sidewalls. The plug strip 11 is adapted to and slidably connected to the slots 15. The first slide bar 13 and the second slide bar 14 slide in contact with the first sliding groove 16 and the second sliding groove 17, respectively. Both the first sliding groove 16 and the second sliding groove 17 are connected to the slots 15. The second slide bar 14 abuts against the outer surface of the cable. The first fixed housing 9 and the second fixed housing 10 are horizontally close to each other. Through the sliding engagement of the first slide bar 13 and the second slide bar 14 with the first sliding groove 16 and the second sliding groove 17, the first fixed housing 9 and the second fixed housing 10 are locked together. The first slide groove 16 and the second slide groove 17 can be slidably engaged with the first slide bar 13 and the second slide bar 14 to fix the first fixed shell 9 and the second fixed shell 10. In order to prevent them from falling off each other, a number of screw holes 18 are opened on one side wall of the slot 15. The screw holes 18 are screwed with second screws 19, which are detachably connected to the expansion groove 12. The expansion groove 12 at one end of the insert 11 is expanded by the second screws 19, and the two sides of the insert 11 are tightly fitted with the inner wall of the slot 15 to achieve a stable fixation of the insert 11 in the expansion groove 12.

[0027] Furthermore, during the mating process of the first fixing shell 9 and the second fixing shell 10, grooves are provided on their mating end faces to accommodate the cable. To ensure smooth mating, volatile lubricating oil needs to be sprayed into the grooves to facilitate the sliding of the first fixing shell 9 and the second fixing shell 10 on the outer side of the cable. This is prior art and will not be described in detail here.

[0028] A further optimized design includes an inner core 1 and an outer sheath 2. A pull wire 5 is positioned inside the outer sheath 2 and is wound in a spiral shape at equal intervals. A first fixing shell 9 and a second fixing shell 10 are respectively fitted onto the outer side of the spiral structure of the pull wire 5. The spiral structure of the pull wire 5 increases the connection strength between the pull wire 5 and the cable, thereby increasing the upper limit of the tensile force on the cable.

[0029] The design has been further optimized, with insert 11 made of hard rubber.

[0030] The working process of this embodiment is as follows: When the cable is subjected to external tension, it slides along the spiral groove 4 of the retaining ring 3. Because the connector 6 is elastic, it allows for a certain degree of relative displacement between the retaining rings 3, thereby releasing the accumulated cable length, reducing the tensile strength on the original length of the cable, and improving cable safety. Simultaneously, the spiral structure of the pull wire 5 is tightly connected to the cable, effectively enhancing the cable's original strength, sharing the tensile force borne by the inner core 1, and further preventing cable damage.

[0031] By adjusting the position and number of fasteners on the cable, the different spiral positions of the pull wire 5 can be fixed according to the actual situation, thereby adjusting the tensile force borne by the cable. When it is necessary to increase the tensile strength of the cable, the number of fasteners is increased or their positions are adjusted to make the connection between the pull wire 5 and the cable tighter; when it is necessary to reduce the tensile force borne by the cable, the number of fasteners is reduced or their positions are adjusted to allow the cable to slide more freely and release the tensile force.

[0032] Furthermore, during installation and use, the chamfered edge design of the spiral groove 4 makes it easier for cables to be inserted into and removed from the spiral groove 4, preventing cables from coming off the groove. The elastic design of the connector 6 and the stable connection between the end 7 and the retaining ring 3 ensure the stability and reliability of the entire auxiliary assembly. Even under large tensile forces, there will be no problem of the connector 6 falling off and causing cable failure.

[0033] In summary, this utility model, through its unique structural design, effectively releases the tension of the cable and significantly improves its tensile strength. It also features flexible fixing and adjustment functions, enabling it to adapt to different usage scenarios and greatly improving the safety and reliability of the cable.

[0034] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
