[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cable with tensile strength and bending resistance is provided in an embodiment of the present invention, the cable includes a first connecting block 2, a second connecting block 6 and a tensioning rope 4, the first connecting block 2 and the second connecting block 6 have the same structure, the first connecting block 2 and the second connecting block 6 are both provided with mounting holes 11, one end of the tensioning rope 4 passes through the two groups of mounting holes 11 of the first connecting block 2, and the other end of the tensioning rope 4 passes through the two groups of mounting holes 11 of the second connecting block 6, the two ends of the tensioning rope 4 are respectively fixedly connected with a first connecting ring 7 and a second connecting ring, a group of springs 8 are fixedly arranged between the first connecting ring 7 and the second connecting ring, and a coating layer 1 is arranged on the periphery of the first connecting block 2 and the second connecting block 6.
[0021] In this embodiment, when not in use, the spring 8 is in a contracted state, thereby tightening the tensioning rope 4. Since the tensioning rope 4 passes through the mounting holes 11 provided on the first connecting block 2 and the second connecting block 6, the tensioning rope 4 will tend to stretch under the tension of the spring 8, thereby utilizing the tensioning rope 4 to tension the first connecting block 2 and the second connecting block 6 so that the two tend to approach each other. The first connecting block 2 and the second connecting block 6 are both fixedly connected to the covering layer 1, so the covering layer 1 is in a compressed state at this time and does not bear the tensioning force. When in use, if The cable is in a situation where tensioning is required, such as when the cable is pulled from a low floor to a high floor. Although the cable itself does not need to bear other external forces, the cable itself has its own weight. Especially when the vertical installation span is large, the cable body will generate a large pulling force. At this time, it will be in a tensioning state under the action of its own weight. Since the coating layer 1 has a certain elasticity, the coating layer 1 has a tendency to stretch under the tensioning action. The coating layer 1 is fixedly connected to the first connecting block 2 and the second connecting block 6. Then the tensioning force borne by the coating layer 1 will be transmitted to the first connecting block 2 and the second connecting block 6, then the spacing between the first connecting block 2 and the second connecting block 6 tends to increase. At this time, under the tensioning action of the first connecting block 2 and the second connecting block 6, the tension on the tensioning rope 4 gradually increases, and the spring 8 will also gradually stretch. Then the tension on the cable will be transferred to the tensioning rope 4, and the spring 8 will provide a buffer, thereby protecting the sheath 1 and the inner core wire. During use, if the cable needs to be bent, at this time, the cable is in a bent state as a whole, and at this time, the first connecting block 2 and the second connecting block 6 will be at a certain angle. Due to the deflection, the two are no longer in a parallel state. In this state, one side of the first connecting block 2 and the second connecting block 6 will be close to each other, which is defined as the inward-turned side, and the other side is defined as the outward-turned side. Obviously, the distance between the outward-turned sides on the first connecting block 2 and the second connecting block 6 will be greater than the distance between the inward-turned sides. However, at this time, since the tensioning rope 4 is not fixedly connected to the first connecting block 2 and the second connecting block 6, the tensioning rope 4 located between the inward-turned sides will slide to the outward-turned side to form compensation. At this time, the bending effect is on the outside of the tensioning rope 4, which improves the overall bending resistance of the cable.
[0022] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, a plurality of limit rings 5 are fixedly arranged on the inner wall of the coating layer 1, the limit rings 5 are fixedly connected to the inner wall of the coating layer 1, the tensioning rope 4 passes through the limit rings 5, and the limit rings 5 are used to limit the movement range of the first connecting ring 7 and the second connecting ring.
[0023] In this embodiment, a plurality of limit rings 5 are fixedly arranged on the inner wall of the coating layer 1, and the limit rings 5 are used to limit the movement range of the first connecting ring 7 and the second connecting ring, thereby ensuring that the first connecting ring 7 and the second connecting ring can move within a fixed range and preventing the spring 8 from approaching the first connecting block 2 and the second connecting block 6 and causing damage.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the first connecting ring 7 and the second connecting ring are both fixedly provided with a first magnetic block, the limiting ring 5 is fixedly provided with a second magnetic block, and the magnetic poles of the adjacent sides of the first magnetic block and the second magnetic block are the same.
[0025] In this embodiment, by providing the first magnetic block and the second magnetic block, it is possible to avoid contact between the limiting ring 5 and the first connecting ring 7 and the second connecting ring, thereby reducing friction therebetween and improving service life.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the first connecting block 2 is connected to the nearest second connecting block 6 via a connecting rod 9.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the core of the first connecting block 2 and the second connecting block 6 is provided with a through hole, the outer edge of the first connecting block 2 and the second connecting block 6 is provided with an installation groove 10, the installation groove 10 and the sheath 1 form an installation space, the installation space is used to set the outer core wire 3, and the through hole of the core of the first connecting block 2 and the second connecting block 6 is used to install the inner core wire.
[0028] In this embodiment, there are multiple mounting grooves 10 , so multiple outer core wires 3 can be installed.
[0029] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, a protective layer is provided on the periphery of the coating layer 1, and a lubricating layer is provided on the inner wall of the coating layer 1.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the coating layer 1 is fixedly connected to the first connecting block 2 and the second connecting block 6 .
