[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1.

Compared with the existing wire protection materials, the protection effect is greatly improved.

The external epoxy resin coating can increase the service life of the wire and ensure the stability and durability of the protective cover body in harsh environments. When the wire accidentally contacts other hardware (such as a pull rod), the copper alloy on the outer layer of the wire has a more wear-resistant performance, thereby improving the protection ability of the protective cover.

[0038] 4. In the present invention, the heat dissipation holes accelerate the dissipation of heat generated when the wire is working, the reinforcing rib structure inside the heat dissipation holes improves the overall strength of the protective cover body, the reinforcement layer can effectively prevent the deformation and rupture of the wire and extend the service life of the wire. The shock-absorbing layer can absorb and disperse external impact force and reduce the stress on the wire during deformation. At the same time, it has a certain fire retardant effect and cooperates with the fireproof layer to effectively protect the wire from high temperature damage from flames.

[0082] Three fixing components 7, which include:

[0083] Insertion block 71, spring 73 and handle 75, the insertion block 71 is inserted and connected inside a set of movable holes 1 62, used to connect the two mounting plates 61, so that the protective cover body 1 is tightly sleeved on the surface of the wire, the outer wall of the insertion block 71 is movably inserted inside the mounting groove 64, used to fix the position of the insertion block 71, so that it will not move forward after being fully inserted, and the outer wall of the insertion block 71 is opened with a set of movable holes 2 72;

[0084] The spring 73 is installed at the bottom of the inner wall of the plug block 71, and uses elastic potential energy to push the relevant components to reset. A connecting column 74 is fixedly installed on the top of the spring 73. The bottom of the handle 75 and the top of the connecting column 74 form a fixed installation. The outer wall of the handle 75 is movably sleeved with the plug block 71. When the handle 75 is pulled, the spring 73 is stretched through the connecting column 74 at the bottom to drive the corresponding components to move;

[0085] The inner surface wall of the second movable hole 72 is movably connected with a plurality of latch tongues 76, which are movably inserted into the interior of the positioning groove 63. The bottom ends of the plurality of latch tongues 76 have arc surfaces, which are used to automatically contract when moving forward and prevent the insert block 71 from retreating.

[0086] A plurality of adjustment components 8, comprising:

[0087] Ear block 1 81, rotating shaft 1 82 and rotating shaft 2 84, the outer wall of rotating shaft 1 82 penetrates the surface of ear block 1 81, and two ear blocks 1 81 are installed on one side of the outer wall of each latch 76, so that the ear block 1 81 and the latch 76 are linked to each other;

[0089] In this embodiment, the movable hole 62 and the positioning groove 63 can facilitate the subsequent insertion of the plug block 71. The mounting groove 64 can limit the plug block 71 in one direction to prevent the plug block 71 from continuously moving forward and falling from the inside of the mounting plate 61. The bottom ends of the plurality of latches 76 have an arc surface, which will automatically shrink when squeezed by external force. When the plug block 71 is inserted into the movable hole 62, the latches 76 will shrink into the plug block 71 under the action of the mounting plate 61, so that the plug block 71 continues to move forward. The latches 76 can drive the ear block 81 and the rotating shaft 82 on one side of the outer wall to move, thereby driving the connected When the other side of the connecting arm 83 rotates upward, the second shaft 84 and the second ear block 85 on the other side of the connecting arm 83 rise accordingly, causing the connecting column 74 connected thereto to rise and stretch the spring 73 at the bottom. When the plug block 71 is completely inserted into the movable hole 1 62 and cannot move forward, the latch 76 will be in the corresponding installation groove 64. At this time, the latch 76 is no longer squeezed by external force, and the stretched spring 73 shrinks accordingly, driving the top connecting column 74 to descend and reset. The connecting column 74 drives the other side of the connecting arm 83 to translate with the help of the second shaft 84 and the second ear block 85, thereby pushing the latch 76 out of the insertion hole 62. The cam 76 is a flat plate with a screw thread 74 formed on the bottom of the cam 76. The cam 76 is a flat plate with a screw thread 74 formed on the bottom of the cam 76. The cam 76 is a flat plate with a screw thread 74 formed on the bottom of the cam 76. The cam 76 is a flat plate with a screw thread 74 formed on the bottom of the cam 76. The cam 76 is a flat plate with a screw thread 74 formed on the bottom of the cam 76. The spring 73 then pulls the plug block 71 connected thereto, facilitating the plug block 71 to be withdrawn from the movable hole 62. As the plug block 71 is withdrawn, the two mounting plates 61 can be separated freely, making it convenient for the user to remove the protective cover body 1 for replacement.

[0090] Embodiment 2, according to Figure 1 , Figure 2 as well as Figure 3 As shown, two protective cover bodies 1 include:

[0091] An aluminum sheet sleeve 11, a copper sheet sleeve 12 and two sealing rings 14, the inside of the copper sheet sleeve 12 is inserted and connected with the aluminum sheet sleeve 11, the copper sheet sleeve 12 and the aluminum sheet sleeve 11 are connected by brazing, the outside of the copper sheet sleeve 12 contacts and rubs with other external hardware (pull rod) to protect the internal wires, the outer walls of the two sealing rings 14 are adhered to the inside of the aluminum sheet sleeve 11, and cooperate with the internal wires of the aluminum sheet sleeve 11 to achieve a sealing effect to prevent external pollutants from entering the aluminum sheet sleeve 11, and the outer wall of the copper sheet sleeve 12 is provided with an epoxy resin coating 13, and the epoxy resin coating 13 is used to form a protective film on the surface of the copper sheet sleeve 12 to prevent rust and corrosion.

[0092] In this embodiment, when the protective cover body 1 is in use, the two sealing rings 14 will be respectively sleeved on the two ends of the wire, thereby sealing the internal space of the protective cover body 1, reducing the corrosion of the wire surface and the aluminum sheet sleeve 11 on the inner wall of the protective cover body 1 caused by external pollutants. The copper sheet sleeve 12 and the aluminum sheet sleeve 11 can be separated by soldering, which significantly reduces the risk of electrochemical corrosion caused by the potential difference between the two metals. The epoxy resin coating 13 on the surface of the copper sheet sleeve 12 isolates it from external pollutants such as moisture, grease, dust, etc. The protective cover body 1 can reduce the progress of corrosion of the wire and itself through various methods, which not only improves the protection effect, but also extends the service life of the protective cover body 1.

[0093] Embodiment 3, according to Figure 1-Figure 3 As shown, a set of hinges 2 are fixedly installed between the outer walls of the two protective cover bodies 1. The set of hinges 2 can cover the device on the outer wall of the wire by rotating the two protective cover bodies 1. A set of heat dissipation holes 3 are fixedly inserted with reinforcing ribs 4 on the inner wall. The reinforcing ribs 4 are used to increase the stability of the device structure. The shock-absorbing pads 5 are composed of fine rubber particles and are used to increase the friction between the protective cover body 1 and the wire to prevent the protective cover body 1 from sliding on the surface of the wire.

[0094] In this embodiment, the two protective cover bodies 1 can be freely rotated by means of the hinge 2, so that the user can quickly put it on the surface of the wire to complete the initial fixation of the device. The heat dissipation holes 3 opened on the protective cover body 1 can increase the contact area between the protective cover body 1 and the air, so that the protective cover body 1 can quickly dissipate the heat generated by the wire when working, so that the temperature of the wire is within a reasonable range, avoiding problems such as short circuit and fire caused by high temperature of the wire. The reinforcing ribs 4 inside the heat dissipation holes 3 can prevent the protective cover body 1 from being deformed during use, thereby improving the structural stability of the protective cover body 1. The shock-absorbing pad 5 allows the protective cover body 1 to be stabilized at the position where it needs to be installed, ensuring the protective effect of the protective cover body 1. At the same time, the shock-absorbing pad 5 can also absorb the kinetic energy generated by vibration or friction in the outside world through deformation and contraction, reducing the risk of damage to the wire, which helps to extend the service life of the wire and reduce the failure rate caused by vibration.

[0095] The working principle of the whole mechanism is as follows: the protective cover body 1 realizes the function of free rotation through the hinge 2, which facilitates the user to quickly put the protective cover on the wire and completes the initial fixation of the device. When the protective cover body 1 is in use, the sealing rings 14 at both ends will tightly wrap the two ends of the wire, effectively closing the internal space of the protective cover body 1, preventing external pollutants from contacting the surface of the wire and the internal aluminum sheet cover 11, thereby reducing the risk of corrosion. In addition, the copper sheet cover 12 and the aluminum sheet cover 11 are isolated by soldering technology, which significantly reduces the possibility of electrochemical corrosion caused by the potential difference between the two metals. The surface of the copper sheet cover 12 is also covered with a layer of epoxy resin coating 13, which separates the copper sheet cover 12 from the outside. The protective cover body 1 is isolated from pollutants such as moisture, grease, dust, etc., further enhancing the anti-corrosion effect. At the same time, the carefully designed heat dissipation holes 3 on the protective cover body 1 not only increase the contact area with the air, but also ensure that the heat generated by the wire during operation can be quickly dissipated, so that the wire temperature is kept within a reasonable range, effectively avoiding safety hazards such as short circuit and fire caused by high temperature. In order to enhance the structural stability of the protective cover body 1, reinforcing ribs 4 are also arranged inside the heat dissipation holes 3, which effectively prevents the protective cover from deforming during use. In addition, the shock-absorbing pad 5 increases the friction so that the protective cover body 1 can be firmly installed in the desired position, ensuring its protective effect. The shock-absorbing pad 5 can also absorb external factors through its own deformation and contraction. The kinetic energy generated by vibration or friction reduces the risk of wire damage. The design of the movable hole 62 and the positioning groove 63 is intended to simplify the installation process of the plug block 71. The plug block 71 can be easily inserted into the movable hole 62, and the installation groove 64 plays a one-way limit role, effectively preventing the plug block 71 from accidentally falling off. During the advancement of the plug block 71, it will encounter multiple latches 76 with curved bottom ends. These latches 76 will automatically shrink when encountering external force to facilitate the passage of the plug block 71. Once the plug block 71 completely enters the movable hole 62, the latches 76 will enter the inside of the plug block 71 under the action of the mounting plate 61. This action will trigger a series of chain reactions: the latches 76 drive the ear block 81 and the rotating shaft 82 to move, thereby causing the other end of the connecting force arm 83 to move upward. When the locking cam 76 is in the unlocked position, the locking cam 76 will be in the unlocked position, and the locking cam 76 will be in the unlocked position, so that the locking cam 76 can be locked in the unlocked position.This design not only saves installation time and reduces installation difficulty, but also enables the protective cover body 1 to adapt to installation environments with narrow spaces. When the protective cover body 1 needs to be replaced, the user only needs to pull the handle 75, and the tongue 76 can be pulled out of the positioning groove 63 through the linkage of the connecting column 74, the second rotating shaft 84, the second ear block 85 and the connecting force arm 83. At this time, the spring 73 will pull the plug block 71 connected to its bottom, so that it can be easily pulled out from the movable hole 1 62. With the withdrawal of the plug block 71, the two mounting plates 61 can be separated freely, which is convenient for the user to remove and replace the protective cover body 1.

[0096] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
