DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Refer to the instruction manual Figure 1-3 , a cable with a torsion-resistant structure, e.g. Figure 1 As shown, it includes a main body mechanism 1, a plurality of external protection mechanisms 2 are fixedly installed on the outer wall of the main body mechanism 1, and a plurality of internal limiting mechanisms 3 are provided inside the main body mechanism 1;
[0023] Reference Figure 2 As shown, the main body 1 includes an outer protective sleeve 101, an inner isolation sleeve 102 is provided inside the outer protective sleeve 101, and a plurality of cable cores 103 are wrapped inside the inner isolation sleeve 102. Figure 3As shown, two first card grooves 104 are provided on the inner wall of the outer protective sleeve 101, and the inner cavities of the two first card grooves 104 are clamped with a first clamping block 105 fixedly connected to the inner isolation sleeve 102, and two second card grooves 106 are provided on the outer wall of the inner isolation sleeve 102, and the inner cavities of the two second card grooves 106 are clamped with a second clamping block 107 fixedly connected to the outer protective sleeve 101. The purpose of such a setting is to make the outer protective sleeve 101 and the inner isolation sleeve 102 no longer just a traditional limit covering treatment, so that there are multiple points of limit between the outer protective sleeve 101 and the inner isolation sleeve 102, so that the outer protective sleeve 101 and the inner isolation sleeve 102 can maintain synchronous torsion when twisting and bending occur;
[0024] At the same time, a buffer groove 108 is provided in the shape of a circular ring inside the outer protective sleeve 101, and two third clamping blocks 109 are fixedly installed in the inner cavity of the buffer groove 108. A guide ring 110 is provided in the inner cavity of the buffer groove 108. The guide ring 110 and the two third clamping blocks 109 are fixedly connected, and the guide ring 110 and the first clamping block 105 are slidably connected. In actual use, when the outer protective sleeve 101 is twisted, the guide ring 110 can be driven to move synchronously by the third clamping block 109, thereby causing the guide ring 110 to slide inside the first clamping block 105. Among them, a telescopic spring 111 is fixedly installed between the third clamping block 109 and the first clamping block 105. Under normal circumstances, the telescopic spring 111 is in an extended state and is arranged between the third clamping block 109 and the first clamping block 105. Therefore, when the third clamping block 109 drives the guide ring 110 to slide inside the first clamping block 105, the telescopic spring 111 can be squeezed to shrink. Then, when the outer wall of the outer protective sleeve 101 loses the external force torsion, the elastic restoring force of the telescopic spring 111 can push the third clamping block 109 to rebound and return to its original position, thereby driving the outer protective sleeve 101 to return to its original position.
[0025] Among them, reference Figure 2 As shown, the two first clamping blocks 105 are symmetrically arranged about the horizontal center line of the inner isolation sleeve 102, and the two second clamping blocks 107 are symmetrically arranged about the vertical center line of the inner isolation sleeve 102. The purpose of such arrangement is to make the two first clamping blocks 105 and the two second clamping blocks 107 arranged in a circular shape and equidistantly in sequence around the circumference of the inner isolation sleeve 102, so that the multiple limit points between the outer protective sleeve 101 and the inner isolation sleeve 102 are subjected to balanced force, wherein the two third clamping blocks 109 are symmetrically arranged about the vertical center line of the inner isolation sleeve 102, and the two third clamping blocks 109 and the second clamping blocks 107 are fixedly installed on the same horizontal line under normal conditions.
[0026] Further, refer to Figure 1-2As shown, the external protective mechanism 2 includes a plurality of limiting rings 21 fixedly installed on the outer wall of the outer protective sleeve 101. The plurality of limiting rings 21 are linearly and equidistantly arranged in a horizontal direction along the outer wall of the outer protective sleeve 101, and a plurality of first reinforcing ribs 22 arranged in a spiral shape are fixedly installed between every two limiting rings 21. The purpose of such arrangement is to enhance the uniformity of the force on the outer wall of the outer protective sleeve 101, so that after torsion occurs, when the first reinforcing ribs 22 restore their own restoring force to restore the original state, the outer wall of the outer protective sleeve 101 can be simultaneously driven to restore its original state, so as to maintain the flatness of the outer protective sleeve 101 after twisting, thereby ensuring that the outer wall of the cable will not be permanently deformed after twisting, thereby enhancing the long-term stability of the cable.
[0027] Among them, multiple first reinforcing ribs 22 are arranged in a ring-shaped and equidistant state around the outer circumferential surface of the outer protective sleeve 101, and the first reinforcing ribs 22 arranged between each two limiting rings 21 are arranged in a staggered state. By making the installation positions of the multiple first reinforcing ribs 22 arranged between each two limiting rings 21 arranged on the outer wall of the outer protective sleeve 101 staggered, when the outer wall of the outer protective sleeve 101 is twisted and bent, its force point is only in a single range, and will not affect the unbent and twisted parts.
[0028] Further, refer to Figure 3 As shown, the built-in limiting mechanism 3 includes a second reinforcing rib 31 provided at the horizontal centerline of the inner isolation sleeve 102. The outer wall of the second reinforcing rib 31 is covered with an insulating sleeve 32, and the outer wall of the insulating sleeve 32 is fixedly mounted with a plurality of insulating partitions 33 fixedly connected to the inner isolation sleeve 102. The purpose of such a setting is to enable the inner cavity of the inner isolation sleeve 102 to be supported by the multi-directional pressure of the plurality of insulating partitions 33, so as to prevent the inner isolation sleeve 102 from being easily deformed.
[0029] Among them, each cable core 103 is arranged between two adjacent insulating partitions 33, and multiple cable cores 103 and multiple insulating partitions 33 are arranged in a ring-shaped and equidistant state around the outer circumferential surface of the insulating sleeve 32. The purpose of such arrangement is to be used to limit and separate the multiple cable cores 103 and place them separately. When twisting occurs, the insulating partition 33, the insulating sleeve 32 and the inner isolation sleeve 102 are fixed to each other, which can drive the cable core 103 to twist synchronously with them, thereby maintaining the synchronization between the inner isolation sleeve 102 and the multiple cable cores 103, and then improving the stability between the cable core 103 and the inner isolation sleeve 102.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
