Description

Technical Field

[0001] The utility model relates to the field of cables, and more specifically, to an outer protective sleeve for a cable. Background Technique

[0002] A cable is a device for transmitting electric energy or signals. It is usually a cable similar to a rope formed by twisting several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The whole is wrapped with a highly insulating covering layer. Cables have the characteristics of being energized inside and insulated outside. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single-strand or multi-strand wires and an insulating layer, and are used to connect circuits, electrical appliances, etc. In actual situations, cables need to be connected through connectors to increase the length of the cables.

[0003] Some existing cable joints are not provided with protective sleeves. Some cables are installed outdoors. After long-term use, the joints may become loose, and then dust or rainwater may enter, which may affect the transmission efficiency of the cables. Therefore, in order to solve the above problems, we propose an outer protective sleeve for a cable. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides an outer protective sleeve for a cable, and adopts the following technical solutions:

[0005] An outer protective sleeve for a cable, including a protective tube. Sealing rings are fixedly installed on the inner walls at both ends of the protective tube. A sleeve is rotatably installed on the outer side of the protective tube. A plurality of protective plates are arranged on the outer side of the sleeve in an annular array. And a plurality of buffer components are arranged in a linear array between the inner side of the protective plate and the outer side of the sleeve. Screw components are arranged at both ends of the protective tube.

[0006] By adopting the above technical scheme, when the equipment is used, the staff sets the protective tube sleeve on the side wall of the cable, then connects the two cables through the connector, and then moves the protective tube to the two cable connections, so as to protect the cable connections. The sealing ring is set in the protective tube, and the inner wall of the sealing ring is tightly fitted with the outer side of the cable, which plays the role of sealing the port of the protective tube, which helps to prevent rainwater and dust from entering the inside of the protective tube. When the position of the protective tube is adjusted, it can be fixed to the side wall of the cable by a screw assembly, which can play the role of fixing the protective tube. The outer side of the protective tube is set by the protective plate, which plays the role of protecting the cable. A buffer assembly is provided between the protective plate and the sleeve. When a foreign object hits the protective plate, the protective plate pushes the buffer assembly to expand and contract, and the buffer assembly plays a buffering role, thereby playing the role of protecting the cable. The sleeve is rotatably installed on the side wall of the protective tube, and the protective plate is forced to rotate with the sleeve, which can play the role of dispersing the impact force. The protective tube not only plays the role of protecting the cable, but also plays the role of pulling the two cables, which helps to prevent the cable connection from loosening or being affected by dust and rainwater, and is beneficial to maintaining the transmission efficiency of the cable.

[0007] Furthermore, the buffer assembly includes multiple groups of pillars fixedly installed on the outside of the sleeve, the pillars in the same group are distributed in a linear array on the outside of the sleeve, the pillars are provided with movable grooves on the side away from the sleeve, support rods are slidably installed in the movable grooves, springs are fixedly connected between the inner wall of the side of the support rod close to the sleeve and the side opposite to the movable groove of the same group, and the support rods in the same group are fixedly connected at one end away from the sleeve and the side opposite to the protective plate of the same group.

[0008] By adopting the above technical solution, when a foreign object hits the protective plate, the protective plate pushes the support rod to slide in the same group of movable grooves, and the support rod pushes the same group of springs to contract. The springs give the same group of support rods a rebound force, so that the support rods push the same group of protective plates to move outward, thereby playing a buffering role, which is beneficial to reduce the damage to the cable and achieve the effect of protecting the cable.

[0009] Furthermore, two symmetrically distributed limit blocks are fixedly mounted on the side wall of the support rod close to one end of the sleeve, and the inner wall of the movable groove is provided with a limit groove matching the limit blocks in the same group.

[0010] By adopting the above technical solution, when the support rod slides in the movable groove, the support rod slides with the limit block in the limit groove on the same side. The cooperation between the limit block and the limit groove is conducive to maintaining the sliding stability of the support rod and helps to prevent the support rod from leaving the movable groove.

[0011] Further, the screwing assembly includes a plurality of fastening blocks fixedly installed on both sides of the protective tube. The plurality of fastening blocks are annularly and arrayedly distributed on the side wall of the protective tube. Nuts are sleeved on the side walls of the same group of fastening blocks, and thread teeth matching the nuts of the same group are provided on the side walls of the same group of fastening blocks and the side walls at both ends of the protective tube.

[0012] By adopting the above technical solution, the staff sleeved two nuts on the side walls of the two cables respectively, and then sleeved the protective tube on the side wall of the cable. After the cables are docked, the staff placed the protective tube in a suitable position, and then screwed the nut with the thread teeth provided on the side wall of the fastening block. Under the continuous screwing force of the nut, the inner side of the fastening block is closely attached to the outer side of the cable, which can play a role in fixing the protective tube, and thus play a role in protecting the connection of the cable.

[0013] Further, two symmetrically distributed rotating rings are fixedly installed on the side wall of the sleeve, and annular grooves matching the rotating rings of the same group are provided on the outer side of the protective tube.

[0014] By adopting the above technical solution, when the sleeve rotates, the sleeve drives the rotating rings to rotate in the annular grooves of the same group. Through the cooperation of the two rotating rings, it is beneficial to maintain the stability of the rotation of the sleeve.

[0015] Further, an oil storage cavity is provided in the protective tube, and two groups of symmetrically distributed heat conducting columns are fixedly installed in the oil storage cavity. One ends of the heat conducting columns close to the protective plate penetrate through the protective tube.

[0016] By adopting the above technical solution, there is an oil storage cavity in the protective tube, and heat conducting oil is provided in the oil storage cavity. The heat conducting oil can play a role in absorbing heat, and the heat can be discharged through the heat conducting columns, thereby playing a role in heat dissipation.

[0017] Further, two groups of symmetrically distributed air vent holes are provided on the side wall of the protective tube. Each group of air vent holes has two and is symmetrically distributed on the side wall of the protective tube. Waterproof breathable membranes are provided in the air vent holes.

[0018] By adopting the above technical solution, through the opening of the air vent holes inside the protective tube, the air circulation efficiency is increased, achieving the effect of heat dissipation. And waterproof breathable membranes are provided in the air vent holes, which can play a role in waterproofing and help prevent water vapor from entering the inside of the protective tube through the air vent holes, achieving the effect of waterproofing.

[0032] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-5 drawings.

[0033] Please refer to Figures 1-5 , a cable outer protective sleeve, which includes a protective tube 1. Sealing rings are fixedly installed on the inner walls at both ends of the protective tube 1. A sleeve 12 is rotatably installed on the outside of the protective tube 1. Multiple protective plates 2 are arranged on the outside of the sleeve 12 in an annular array. Screw assembly components are provided at both ends of the protective tube 1. The screw assembly components include multiple fastening blocks 6 fixedly installed on both sides of the protective tube 1. The multiple fastening blocks 6 are annularly arrayed on the side wall of the protective tube 1. Nuts 3 are sleeved on the side walls of the same group of fastening blocks 6. Threaded teeth matching the nuts 3 of the same group are opened on the side walls of the same group of fastening blocks 6 and the side walls at both ends of the protective tube 1. When the device is in use, the staff sleeved the two nuts 3 on the side walls of the two cables respectively, and then sleeved the protective tube 1 on the side wall of the cable. After the cable docking is completed, the staff placed the protective tube 1 in a suitable position, and then screwed the nut 3 with the threaded teeth opened on the side wall of the fastening block 6. Under the continuous screwing force of the nut 3, the inner side of the fastening block 6 is closely attached to the outer side of the cable, which can play a role in fixing the protective tube 1, and thus play a role in protecting the cable connection.

[0034] Multiple buffer components are arranged in a linear array between the inner side of the protective plate 2 and the outer side of the sleeve 12. The buffer components include multiple groups of struts 7 fixedly installed on the outer side of the sleeve 12. The same group of struts 7 are linearly arrayed on the outer side of the sleeve 12. Activity slots 13 are opened on the sides of the struts 7 away from the sleeve 12. Support rods 8 are slidably installed in the activity slots 13. Springs 14 are fixedly connected between the sides of the support rods 8 close to the sleeve 12 and the inner walls of the opposite sides of the same group of activity slots 13. The ends of the same group of support rods 8 away from the sleeve 12 are fixedly connected to the opposite sides of the same group of protective plates 2.

[0035] When an external object impacts the protection plate 2, the protection plate 2 pushes the support rod 8 to slide within the same group of movable slots 13. The support rod 8 pushes the spring 14 of the same group to contract, and the spring 14 gives a rebounding force to the support rod 8 of the same group, causing the support rod 8 to push the protection plate 2 of the same group to move outward, thereby playing a buffering role, which is beneficial to reducing the damage degree suffered by the cable and achieving the effect of protecting the cable. Moreover, the sleeve 12 is rotatably installed on the side wall of the protection tube 1. When the protection plate 2 is stressed, it drives the sleeve 12 to rotate, which can play a role in dispersing the impact force. Two symmetrically distributed rotating rings 11 are fixedly installed on the side wall of the sleeve 12, and annular grooves matching the rotating rings 11 of the same group are opened on the outside of the protection tube 1. When the sleeve 12 rotates, the sleeve 12 drives the rotating rings 11 to rotate within the annular grooves of the same group. Through the cooperation of the two rotating rings 11, it is beneficial to maintain the stability of the rotation of the sleeve 12.

[0036] Two symmetrically distributed limiting blocks are fixedly installed on the side walls of the ends of the support rod 8 close to the sleeve 12, and limiting grooves matching the limiting blocks of the same group are opened on the inner wall of the movable slot 13. When the support rod 8 slides within the movable slot 13, the support rod 8 drives the limiting blocks to slide within the limiting grooves on the same side. Through the cooperation of the limiting blocks and the limiting grooves, it is beneficial to maintain the stability of the sliding of the support rod 8 and helps to prevent the support rod 8 from detaching from the movable slot 13.

[0037] An oil storage cavity 10 is opened in the protection tube 1. Two symmetrically distributed heat conducting columns 4 are fixedly installed in the oil storage cavity 10. The ends of the heat conducting columns 4 close to the protection plate 2 all penetrate through the protection tube 1. There is an oil storage cavity 10 in the protection tube 1, and heat conducting oil is provided in the oil storage cavity 10. The heat conducting oil can play a role in absorbing heat, and the heat can be discharged through the heat conducting columns 4, thereby playing a role in heat dissipation.

[0038] Two symmetrically distributed air vent holes 9 are opened on the side wall of the protection tube 1. Each group of air vent holes 9 consists of two and is symmetrically distributed on the side wall of the protection tube 1. Waterproof breathable membranes 5 are provided in the air vent holes 9. Through the opening of the air vent holes 9 inside the protection tube 1, the air circulation efficiency is increased, achieving the effect of heat dissipation. Moreover, the waterproof breathable membranes 5 are provided in the air vent holes 9, which can play a role in waterproofing and help to prevent water vapor from entering the inside of the protection tube 1 through the air vent holes 9, achieving the waterproof effect.

[0039] The implementation principle of the embodiment of the utility model is as follows: when the device is used, the staff sets the protective tube 1 on the side wall of the cable, then connects the two cables through the connector, and then moves the protective tube 1 to the two cable connections, so as to protect the cable connections. The protective tube 1 is provided with a sealing ring, and the inner wall of the sealing ring is tightly fitted with the outer side of the cable, so as to seal the port of the protective tube 1, which helps to prevent rainwater and dust from entering the protective tube 1. After the position adjustment of the protective tube 1 is completed, it can be fixed to the side wall of the cable by a screw assembly, so as to fix the protective tube 1. The outer side of the protective tube 1 is provided with a protective plate 2, so as to protect the cable. A buffer assembly is provided between the protective plate 2 and the sleeve 12. When a foreign object hits the protective plate 2, the protective plate 2 pushes the buffer assembly to retract, and the buffer assembly plays a buffering role, thereby playing a role in protecting the cable. The sleeve 12 is rotatably installed on the side wall of the protective tube 1, and the protective plate 2 is forced to rotate with the sleeve 12, so as to disperse the impact force, which helps to prevent the cable connection from loosening or being affected by dust and rainwater, and is beneficial to maintaining the transmission efficiency of the cable.
