The entire outside is covered with a highly insulating covering. They are mostly installed in the air or underground or underwater for telecommunications or power transmission. Therefore, the cable needs to withstand its own gravity to prevent it from breaking. At the same time, it is also necessary to prevent the cable from breaking due to external forces.

[0003] In the announcement number CN206516374U, a tensile-resistant cable is disclosed, which includes a tensile reinforcement, a power conductive core, a control conductive core, a filling core, an anti-torsion isolation layer, and an outer sheath; the tensile reinforcement is located at the center of the tensile-resistant cable, the control conductive core is first twisted together to form an integral control unit, and then twisted with the power conductive core and the filling core to form a cable integral unit on the periphery of the tensile reinforcement, and the anti-torsion isolation layer and the outer sheath are sequentially wrapped around the periphery of the above-mentioned cable integral unit from the inside to the outside. The tensile-resistant cable provided by the utility model has the advantages of good flexibility, good tensile strength, long service life, oil resistance, wear resistance, and good mobility; but the structure of the tensile-resistant cable is relatively simple, and it is impossible to block and disperse rats and insects. When the cable is placed, the surrounding rats and insects are easy to damage the cable, resulting in a reduction in the service life of the cable. Therefore, it is necessary to provide a safe tensile-resistant cable to solve the above problems. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a safe tensile-resistant cable, including: a cable core, a first protective sleeve is connected to the outside of the cable core, and a second protective sleeve is connected to the outside of the first protective sleeve, and a reinforcement sleeve is arranged on the outside of the second protective sleeve, a third protective sleeve is connected to the outside of the reinforcement sleeve, and the third protective sleeve is fixedly connected to the middle position of the left and right sides of the third protective sleeve, and two groups of vertical mounting plates are connected by clamping blocks.

[0006] As a further solution of the present invention, the cable cores are provided in three groups in total, and the first protective sleeves are tightly wrapped around the outer surface of the cable cores.

[0007] As a further solution of the present invention, the second protective sleeve is provided in an armored structure, and an insulating layer is provided on the inner wall of the second protective sleeve.

[0008] As a further solution of the present invention, reinforcement frames are evenly distributed inside the reinforcement sleeve, and the reinforcement frames are arranged in an X-shaped structure, and both ends of the reinforcement frames are fixedly connected to the inner wall of the reinforcement sleeve.

[0009] As a further solution of the present invention, rubber convex strips are evenly distributed on the outer surface of the third protective sleeve, and through holes are evenly opened on the third protective sleeve.

[0010] As a further solution of the present invention, a glass fiber layer is provided on the inner wall of the third protective sleeve, and the third protective sleeve is provided in an arc-shaped structure and wrapped around the upper and lower ends of the reinforcement sleeve.

[0013] In summary, the utility model includes at least one of the following beneficial technical effects:

[0014] First, the utility model records a safe tensile cable, which records that by setting the second protective cover in an armored structure, in order to protect the integrity of the cable structure and electrical performance and improve the service life of the cable, it is very necessary to add an armor layer to the outer sheath of the cable. Secondly, the armor layer can reduce the impact of mechanical force on the cable, so that the mechanical force acting on the cable is borne by the armor layer. In addition, the armored cable can better withstand radial pressure, adopting a double steel belt and gap wrapping process, which is called a steel belt armored cable. Finally, the armor layer can prevent the internal utility layer from being damaged during transportation and installation;

Since the two sets of installation plates are movably clamped together by the clamping blocks, the third protective cover is more convenient to install and disassemble, which increases the practicality of the device.

[0024] Please refer to Figure 1-6 A safety tensile cable, comprising:

[0025] A cable core 1, a first protective sleeve 2 is connected to the outside of the cable core 1, and a second protective sleeve 3 is connected to the outside of the first protective sleeve 2, and a reinforcement sleeve 4 is arranged on the outside of the second protective sleeve 3, and a third protective sleeve 5 is connected to the outside of the reinforcement sleeve 4, and the third protective sleeve 5 is fixedly connected to the middle position of the left and right sides thereof with a mounting plate 6, and two sets of vertical mounting plates 6 are connected by a clamping block 7.

[0026] Furthermore, the cable core 1 is provided with three groups, the first protective cover 2 is tightly wrapped on the outer surface of the cable core 1, the second protective cover 3 is provided with an armored structure, and an insulating layer is provided on the inner wall of the second protective cover 3. The function of adding the armor layer to the cable is mainly to enhance the mechanical protection properties of the cable such as tensile strength and compressive strength, thereby extending its service life. In addition, through shielding protection, the armor layer can also improve the anti-interference performance of the cable. The armor layer can effectively prevent the internal utility layer from being damaged during transportation and installation, and ensure the integrity and electrical performance of the cable structure. The commonly used armor The armor materials include steel belt, steel wire, aluminum belt, aluminum tube, etc. Among them, the steel belt and steel wire armor layer have high magnetic permeability. When selecting the cable sheath, the actual needs and related requirements should be considered. For example, when it is necessary to enhance the cable's resistance to external forces, a non-magnetic metal armor layer should be selected, and steel armor that has not been effectively treated with non-magnetic properties should not be selected. The main function of the cable insulation layer is to protect the conductor of the cable and prevent it from short-circuiting with the surrounding environment or adjacent conductors, thereby avoiding equipment damage and harm to the human body. Both the conductor and the non-conductor part need to be effectively isolated by the insulation layer.

[0027] Furthermore, reinforcement frames are evenly distributed inside the reinforcement sleeve 4, and the reinforcement frames are arranged in an X-shaped structure. Both ends of the reinforcement frames are fixedly connected to the inner wall of the reinforcement sleeve 4. By providing the reinforcement sleeve 4, the device is more secure when in use, and the service life of the device is increased. By arranging the reinforcement frames in an X-shaped structure, the stability of the reinforcement sleeve 4 when in use can be increased.

[0028] Furthermore, the outer surface of the third protective sleeve 5 is evenly distributed with rubber convex strips, the third protective sleeve 5 is evenly provided with through holes, a glass fiber layer is arranged on the inner wall of the third protective sleeve 5, and the third protective sleeve 5 is arranged in an arc-shaped structure and wrapped around the upper and lower ends of the reinforcement sleeve 4. The rubber convex strips can protect the third protective sleeve 5, and the through holes on the third protective sleeve 5 can be filled with rodent and insect-proof drugs to protect the device, thereby increasing the protectiveness of the device. Glass fiber is an inorganic non-metallic material with excellent performance and a wide variety of types. It has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. Secondly, glass fiber reinforced plastic Cable trays have the characteristics of light weight, high strength, corrosion resistance, and good insulation performance. In addition, after glass fiber reinforcement, the addition of glass fiber limits the mutual movement between the polymer chains of the plastic. Therefore, the shrinkage rate of the reinforced plastic is greatly reduced and the rigidity is greatly improved; reinforced plastics will not stress crack, and at the same time, the impact resistance of the plastic is greatly improved; glass fiber is a high-strength material, which also greatly improves the strength of the plastic, such as: tensile strength, compression strength, and bending strength, which are greatly improved; due to the addition of glass fiber and other additives, the combustion performance of reinforced plastics is greatly reduced, and most materials cannot be ignited, and it is a flame retardant material.

[0029] Furthermore, both left and right ends of the two groups of third protective sleeves 5 are fixedly connected with mounting plates 6, and the lower surface of one group of mounting plates 6 is fixedly connected with a clamping block 7, and the left and right sides of the clamping block 7 are fixedly connected with rubber clamping balls, and the other group of mounting plates 6 is provided with a clamping groove that matches the clamping block 7 and the rubber clamping ball. By providing the mounting plates 6 and the clamping blocks 7, the two groups of third protective sleeves 5 can be wrapped around the outer surface of the reinforcement sleeve 4, and then the third protective sleeve 5 can be installed and fixed by the mounting plates 6 and the clamping blocks 7, and the clamping blocks 7 are clamped in the grooves of one group of mounting plates 6. By providing rubber clamping balls on the left and right sides of the clamping blocks 7, the clamping blocks 7 are more secure when clamped.

[0030] Working principle: When in use, wrap two sets of third protective sleeves 5 on the outer surface of the reinforcement sleeve 4, and then install and fix the third protective sleeve 5 through the mounting plate 6 and the clamping block 7, and engage the clamping block 7 in the groove of one set of mounting plates 6. The above is the entire working principle of the utility model.
