Description

Technical Field

[0001] The invention relates to the technical field of control cables, in particular to a fireproof, fire-resistant and flame-retardant shielded control cable. Background Art

[0002] With the acceleration of urbanization and people's emphasis on the safety of life and property, the fire safety requirements for buildings and facilities are getting higher and higher. Fire-proof, fire-resistant and flame-retardant shielded control cables can maintain the integrity of the circuit when a fire occurs, and provide necessary power and signal support for personnel evacuation and fire extinguishing. In some important electrical equipment and systems, such as power systems, communication systems, and automation control systems, the reliability requirements for cables are very high. Fire-proof, fire-resistant and flame-retardant shielded control cables can maintain good electrical properties under harsh environmental conditions to ensure the normal operation of equipment and systems. Fire-proof, fire-resistant and flame-retardant shielded control cables are usually made of halogen-free, low-smoke and flame-retardant materials, which can reduce environmental pollution when a fire occurs.

[0003] However, during installation, the control cable will fall and hit the ground, causing friction with the ground, and the cable will also be squeezed. When the control cable is pulled or squeezed, the cable's outer skin, insulation layer or shielding layer will be damaged. For fire-resistant, fire-resistant and flame-retardant shielded control cables, their outer skin usually has flame-retardant properties, but in the case of physical damage, the flame retardant effect will be reduced or even lost. If the pulling force is large, the insulation layer inside the cable will be damaged, which will cause a short circuit or leakage, increasing the risk of fire.

[0004] Secondly, the installation of the fixing fixture of the control cable in the prior art is relatively cumbersome. The fixing fixture is fixed by bolt connection. The bolted cable fixing fixture usually requires the use of tools (such as a wrench) to tighten or loosen the bolts to adjust the tightness of the cable. This operation is relatively cumbersome, especially in environments with limited space or difficult access. It is difficult to operate. In environments with large vibrations or shocks, the bolted cable fixing fixture is more likely to loosen, resulting in cable damage or unstable connection, which requires more frequent inspections and maintenance to ensure the safety of the cable.

[0005] Therefore, the present invention proposes a fireproof, fire-resistant and flame-retardant shielded control cable to improve the shortcomings of traditional technology, reduce the damage to the cable caused by friction and extrusion during cable installation, and realize the rapid installation and disassembly of the cable fixing clamp. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a fireproof, fire-resistant and flame-retardant shielded control cable, which solves the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a fire-proof, fire-resistant and flame-retardant shielded control cable, comprising a fixing plate, a conductor is arranged on the top of the fixing plate, a sheath is arranged on the outside of the conductor, a reinforcing layer is fixedly connected to the outer surface of the sheath, an anti-extrusion component for absorbing and dispersing impact force is arranged inside the reinforcing layer, and an auxiliary component for quickly installing and disassembling the cable fixing clamp is arranged on the outside of the reinforcing layer.

[0008] Preferably, the anti-extrusion component includes a component shell, which is fixedly connected to the inner wall of the reinforcement layer, a slide groove is provided inside the component shell, an irregular extrusion block is slidably connected to the inside of the component shell, a return spring is fixedly connected between the bottom of the irregular extrusion block and the inner wall of the slide groove, an auxiliary slider and a movable slider are symmetrically slidably connected to the inside of the slide groove, an airbag is fixedly connected to the upper surface of the component shell, and the interior of the airbag is connected to the interior of the slide groove.

[0009] Preferably, the irregular extrusion block penetrates the interior of the reinforcement layer and is slidably connected thereto.

[0010] Preferably, an inclined groove is provided on the outer surface of the bottom end of the irregular extrusion block, inclined surfaces are provided at both ends of the auxiliary slider, an inclined surface is provided at the bottom end of the movable slider, the inclined surface of the movable slider is parallel to the inclined surface of the auxiliary slider, and the inclined surface at one end of the auxiliary slider away from the movable slider is parallel to the inclined surface of the inclined groove of the irregular extrusion block.

[0011] Preferably, the top size of the movable slider is matched with the size of the slide groove.

[0012] Preferably, the auxiliary component includes a base, the bottom of the base is fixedly connected to the upper surface of the fixed plate, a circular groove hole is opened inside the base, a spring tilting plate is fixedly connected to the inner wall of the circular groove hole, a rotating locking column is threadedly connected to the inner wall of the circular groove hole, a rubber shock-absorbing gasket is fixedly connected to the upper surface of the base, a circular bevel groove is opened on the inner wall of the bottom end of the rotating locking column, a fixed cylinder is movably connected to the interior of the rotating locking column, and a fixed cover plate is fixedly connected to the top of the fixed cylinder.

[0013] Preferably, the top of the spring inclined plate is inclined, and the inclined surface of the annular inclined groove is parallel to the inclined surface of the spring inclined plate.

[0014] Preferably, the bottom end of the rotating locking column passes through the interior of the rubber shock-absorbing gasket.

[0015] The present invention provides the following beneficial effects:

[0016] 1. By arranging equidistantly distributed protrusions on the surface of the reinforcement layer and irregular extrusion blocks inside the protrusions, when the cable falls or is extruded, the first thing that contacts the ground is the protrusions on the cable surface. The reinforcement layer at the protrusions is thicker, which can absorb and disperse the impact force, reduce the direct impact on the conductor, and protect the internal structure of the cable from damage. The protrusion design can reduce the contact area between the cable and the ground and extend the service life of the cable. The irregular extrusion blocks in the protrusions will be squeezed toward the inside of the reinforcement layer. When the irregular extrusion blocks move, they will squeeze the reset spring. The spring has a certain buffer force. The buffer force of the spring can prevent excessive deformation of the cable and protect the wires and insulation layer inside the cable from damage.

[0017] 2. When the irregular extrusion block squeezes the reset spring, the moving slider pushes the gas above the moving slider upward into the interior of the airbag. This design allows the airbag to be propped up and the reset spring to be compressed simultaneously, ensuring that the cable can respond quickly and protect the cable when subjected to external force. The airbag is propped up inside the cable to provide additional support, reducing deformation and damage to the cable when it falls or is squeezed, which helps to protect the structural integrity of the cable and ensure its normal operation. The expansion of the airbag can play a buffering and shock-absorbing role, absorbing the impact force generated when falling or squeezing, which helps to reduce damage to the internal conductor and insulation layer of the cable and extend the service life of the cable. Through the propping up of the airbag, the compressive resistance of the cable is enhanced, which helps to maintain the shape and function of the cable when subjected to external pressure and reduce the risk of the cable being flattened or damaged. If the cable is slightly squeezed or damaged, the propping up of the airbag can make the damaged part more obvious, which is convenient for timely discovery and maintenance and repair work. Once the external force disappears, the airbag can quickly return to its original state and prepare for the next protection.

[0018] 3. The circular bevel groove at the bottom of the rotating locking column is brought into contact with the spring inclined plate by rotating the locking column. The inclination of the circular bevel groove at the bottom of the rotating locking column squeezes the spring inclined plate to apply an extrusion force to the fixed cylinder, so that the fixed cylinder can be locked and fixed, and the cable can be firmly fixed. This design usually only requires a simple rotation action to complete the locking, which is easier to operate and does not require special tools. The design of the circular bevel groove and the spring inclined plate at the bottom of the rotating locking column can adapt to fixed cylinders of different diameters, thereby increasing the flexibility of the design. The rotating locking column will also squeeze the rubber shock-absorbing gasket while rotating. The rubber shock-absorbing gasket has a rebound force. The rotating locking column is threadedly connected to the inner wall of the base. The reaction force of the rubber shock-absorbing gasket can prevent the rotating locking column from loosening, thereby ensuring the fixing effect of the cable. The rebound force of the rubber shock-absorbing gasket can reduce noise and vibration, and improve the comfort of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] refer to Figures 1 to 8 As shown, a preferred embodiment of the present invention will be described in detail below:

[0033] A fireproof, fire-resistant and flame-retardant shielded control cable comprises a fixing plate 1, a conductor 2 is arranged on the top of the fixing plate 1, a sheath 3 is arranged outside the conductor 2, a reinforcing layer 4 is fixedly connected to the outer surface of the sheath 3, a fire-retardant coating is coated on the surface of the reinforcing layer 4 to slow down the spread of fire, an anti-extrusion component 5 for absorbing and dispersing impact force is arranged inside the reinforcing layer 4, and an auxiliary component 6 for quickly installing and disassembling a cable fixing clamp is arranged outside the reinforcing layer 4.

[0034] The anti-extrusion component 5 includes a component shell 51, which is fixedly connected to the inner wall of the reinforcement layer 4. A slide groove 52 is provided inside the component shell 51. An irregular extrusion block 53 is slidably connected to the inside of the component shell 51. A reset spring 54 is fixedly connected between the bottom of the irregular extrusion block 53 and the inner wall of the slide groove 52. The surface of the reinforcement layer 4 is provided with equidistantly distributed protrusions, and irregular extrusion blocks 53 are provided inside the protrusions. In this way, when the cable falls or is extruded, the first thing that contacts the ground is the protruding part of the cable surface. The reinforcement layer 4 at the protruding part is thicker, which can absorb and disperse the impact force, reduce the direct impact on the conductor 2, and protect the internal structure of the cable from damage. The protrusion design can reduce the contact area between the cable and the ground and extend the service life of the cable. The irregular extrusion block 53 in the protrusion will be squeezed toward the inside of the reinforcement layer 4. When the irregular extrusion block 53 moves, it will squeeze the reset spring 54. The spring has a certain buffer force. The buffer force of the spring can prevent excessive deformation of the cable and protect the wire and insulation layer inside the cable from damage.

[0035] The interior of the slide groove 52 is symmetrically slidably connected with an auxiliary slider 55 and a mobile slider 56, and an airbag 57 is fixedly connected to the upper surface of the component housing 51. The interior of the airbag 57 is connected to the interior of the slide groove 52, and the irregular extrusion block 53 penetrates the interior of the reinforcement layer 4 and is slidably connected thereto. An inclined groove is provided on the outer surface of the bottom end of the irregular extrusion block 53, and both ends of the auxiliary slider 55 are provided with inclined surfaces. The bottom end of the mobile slider 56 is provided with an inclined surface. The inclined surface of the mobile slider 56 is parallel to the inclined surface of the auxiliary slider 55. The inclined surface of one end of the auxiliary slider 55 away from the mobile slider 56 is parallel to the inclined surface of the inclined groove of the irregular extrusion block 53. The top size of the mobile slider 56 is adapted to the size of the slide groove 52. When the irregular extrusion block 53 squeezes the reset spring 54, the mobile slider 56 pushes the gas above the mobile slider 56 upward into the interior of the airbag 57. This design allows the airbag 57 to prop up and the compression energy of the reset spring 54 to be The two functions of the cable 52 are synchronized and can be performed synchronously, ensuring that the cable can respond quickly and protect the cable when subjected to external force. The airbag 57 inside the cable can provide additional support to reduce deformation and damage of the cable when it falls or is squeezed, which helps to protect the structural integrity of the cable and ensure its normal operation. The expansion of the airbag 57 can play a buffering and shock-absorbing role, absorbing the impact force generated when it falls or is squeezed, which helps to reduce damage to the internal conductor 2 and the insulation layer of the cable and extend the service life of the cable. Through the support of the airbag 57, the compressive capacity of the cable is enhanced, which helps to maintain the shape and function of the cable when subjected to external pressure and reduces the risk of the cable being flattened or damaged. If the cable is slightly squeezed or damaged, the support of the airbag 57 can make the damaged part more obvious, which is convenient for timely detection and maintenance and repair work. Once the external force disappears, the airbag 57 can quickly return to its original state and prepare for the next protection.

[0036] The auxiliary component 6 includes a base 61, the bottom of the base 61 is fixedly connected to the upper surface of the fixed plate 1, a circular groove hole 64 is opened inside the base 61, a spring inclined plate 66 is fixedly connected to the inner wall of the circular groove hole 64, a rotating locking column 65 is threadedly connected to the inner wall of the circular groove hole 64, a rubber shock-absorbing gasket 68 is fixedly connected to the upper surface of the base 61, a circular bevel groove 67 is opened on the inner wall of the bottom end of the rotating locking column 65, a fixed cylinder 63 is movably connected to the inside of the rotating locking column 65, and a fixed cover plate 62 is fixedly connected to the top of the fixed cylinder 63, the top of the spring inclined plate 66 is inclined, the inclined surface of the circular bevel groove 67 is parallel to the inclined surface of the spring inclined plate 66, the bottom end of the rotating locking column 65 passes through the inside of the rubber shock-absorbing gasket 68, and the circular bevel groove 67 opened at the bottom of the rotating locking column 65 contacts the spring inclined plate 66 by rotating the rotating locking column 65, and the rotating locking column The inclined circular groove 67 at the bottom of 65 squeezes the spring inclined plate 66 to apply an extrusion force to the fixed cylinder 63, so that the fixed cylinder 63 can be locked and fixed, and the cable can be firmly fixed. This design usually only requires a simple rotation action to complete the locking, which is easier to operate and does not require special tools. The design of the circular groove 67 and the spring inclined plate 66 at the bottom of the rotating locking column 65 can adapt to fixed cylinders 63 of different diameters, increasing the flexibility of the design. The rotating locking column 65 will also squeeze the rubber shock-absorbing gasket 68 while rotating. The rubber shock-absorbing gasket 68 has a rebound force. The rotating locking column 65 is threadedly connected to the inner wall of the base 61. The reaction force of the rubber shock-absorbing gasket 68 can prevent the rotating locking column 65 from loosening, thereby ensuring the fixing effect of the cable. The rebound force of the rubber shock-absorbing gasket 68 can reduce noise and vibration, and improve the comfort of use.

[0037] The following is the entire working process and working principle of the above embodiment:

[0038] First, during the process of laying the cable, the installers may fall and hit the ground, causing friction with the ground, and the cable may be squeezed. When the cable is dropped or squeezed, since the surface of the reinforcement layer 4 is provided with equidistantly distributed protrusions, and irregular extrusion blocks 53 are provided inside the protrusions, when the cable falls or is squeezed, the first thing that comes into contact with the ground is the protruding part of the cable surface. The reinforcement layer 4 at the protruding part is thicker, which can absorb and disperse the impact force, reduce the direct impact on the conductor 2, and protect the internal structure of the cable from damage. The protrusion design can reduce the contact area between the cable and the ground and extend the service life of the cable. When the cable falls or is squeezed, the irregular extrusion block 53 in the protrusion will be squeezed toward the inside of the reinforcement layer 4. When the irregular extrusion block 53 moves, it will squeeze the reset spring 54. The spring has a certain buffering force. The buffering force of the spring can prevent the cable from excessive deformation and protect the wires and insulation layer inside the cable from damage.

[0039] Since the outer surface of the bottom end of the irregular extrusion block 53 is provided with an inclined groove, both ends of the auxiliary slider 55 are provided with inclined surfaces, and the bottom end of the moving slider 56 is provided with an inclined surface, the inclined surface of the moving slider 56 is parallel to the inclined surface of the auxiliary slider 55, and the inclined surface of one end of the auxiliary slider 55 away from the moving slider 56 is parallel to the inclined surface of the inclined groove of the irregular extrusion block 53. In the initial state, the two ends of the auxiliary slider 55 are respectively in close contact with the inclined surface of the inclined groove of the irregular extrusion block 53 and the inclined surface of the bottom end of the moving slider 56. When the irregular extrusion block 53 moves downward to squeeze the reset spring 54, it will squeeze the inclined surface of the auxiliary slider 55, and the irregular The regular extrusion block 53 moves downward to squeeze the auxiliary slider 55, while driving the auxiliary slider 55 to move away from the irregular extrusion block 53. The auxiliary slider 55 squeezes the inclined surface at the bottom of the moving slider 56 while moving. When the auxiliary slider 55 squeezes, it drives the moving slider 56 to move upward. In the initial state, the inside of the airbag 57 and the inside of the chute 52 above the moving slider 56 are filled with gas, and the airbag 57 is not propped up at this time. When the moving slider 56 moves upward, the moving slider 56 pushes the gas inside the chute 52 above the moving slider 56 into the inside of the airbag 57, and the airbag 57 is propped up at this time. The expansion of the airbag 57 can play a role in buffering and shock absorption. When the irregular extrusion block 53 squeezes the reset spring 54, the movable slider 56 pushes the gas above the movable slider 56 into the interior of the airbag 57. This design allows the airbag 57 to be propped up and the reset spring 54 to be compressed synchronously, ensuring that the cable can respond quickly and protect the cable when subjected to external force. The airbag 57 propped up inside the cable can provide additional support to reduce deformation and damage of the cable when it falls or is squeezed, which helps to protect the structural integrity of the cable and ensure its normal operation. The expansion of the airbag 57 It can play a role in buffering and shock absorption, absorbing the impact force generated by falling or squeezing, which helps to reduce damage to the internal conductor 2 and the insulation layer of the cable and extend the service life of the cable. By supporting the airbag 57, the compressive resistance of the cable is enhanced, which helps to maintain the shape and function of the cable when subjected to external pressure and reduces the risk of the cable being flattened or damaged. If the cable is slightly squeezed or damaged, the support of the airbag 57 can make the damaged part more obvious, which is convenient for timely detection and maintenance and repair work. Once the external force disappears, the airbag 57 can quickly return to its original state and prepare for the next protection.

[0040] In the initial state, the fixed cylinder 63 is located inside the base 61, and the bottom end of the circular bevel groove 67 is located at the top of the bevel of the spring inclined plate 66. Since the bottom size of the circular bevel groove 67 is larger than the top size of the bevel of the spring inclined plate 66, the spring inclined plate 66 is not squeezed by the rotating locking column 65. The installer puts the cable on the base 61, and then covers the fixed cover plate 62 on the cable, and inserts the fixed cylinder 63 into the circular groove hole 64. The installer rotates the locking column 65. Since the rotating locking column 65 is threadedly connected to the inner wall of the circular groove hole 64, the rotating locking column 65 rotates to The base 61 moves inside, and the rotating locking column 65 moves to make the annular bevel groove 67 move downward, and the inclined surface of the annular bevel groove 67 squeezes the inclined surface of the spring inclined plate 66 to make it close to the fixed cylinder 63 and exert a squeezing force on the fixed cylinder 63, so that the fixed cylinder 63 can be locked and fixed, and the cable can be firmly fixed. The rotating locking column 65 rotates to make the annular bevel groove 67 opened at the bottom of the rotating locking column 65 contact with the spring inclined plate 66, and the inclination of the annular bevel groove 67 opened at the bottom of the rotating locking column 65 squeezes the spring inclined plate 66 to exert a squeezing force on the fixed cylinder 63, so that the fixed cylinder 63 can be locked and fixed. 3 locking and fixing, can firmly fix the cable, this design usually only needs a simple rotation action to complete the locking, the operation is easier, no special tools are required, the design of the circular ring bevel groove 67 and the spring inclined plate 66 at the bottom of the rotating locking column 65 can adapt to the fixed cylinder 63 of different diameters, increasing the flexibility of the design, and the rubber shock-absorbing gasket 68 will be squeezed while the locking column 65 is rotating, and the rubber shock-absorbing gasket 68 has a rebound force, and the rotating locking column 65 is threadedly connected to the inner wall of the base 61, and the reaction force of the rubber shock-absorbing gasket 68 can prevent the rotating lock The tightening column 65 is loose to ensure the fixing effect of the cable. The rebound force of the rubber shock-absorbing gasket 68 can reduce noise and vibration and improve the comfort of use. When disassembling, you only need to reverse the locking column 65. Rotate the locking column 65 so that the bottom end of the circular bevel groove 67 is located at the top of the bevel of the spring inclined plate 66. Since the bottom size of the circular bevel groove 67 is larger than the size of the top of the bevel of the spring inclined plate 66, the spring inclined plate 66 is not squeezed by the rotating locking column 65 at this time, and the spring inclined plate 66 does not exert squeezing force on the fixed cylinder 63. At this time, the fixed cylinder 63 can be taken out of the circular groove hole 64 without fixing the cable.
