For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Embodiment 1: As shown in the attached Figure 1 To Attachment Fig.13 As shown, a hidden auxiliary cable installation device includes a cable installation box 10 and an auxiliary laying claw 11, the cable installation box 10 includes a side plate 12 and two elastic outer expansion plates 13, the two elastic outer expansion plates 13 are connected to the two sides of the side plate 12 to form an open groove 14 for accommodating the cable, and a thermal deformation spring sheet 16 for abutting the cable and a piezoelectric body 60 for driving the thermal deformation spring sheet 16 to actively deform are arranged on the side plate 12, and a buckle 15 is arranged between the two elastic outer expansion plates 13, the thermal deformation spring sheet 16 and the buckle 15 clamp the cable in the center of the open groove 14, and the buckle 15 moves away from the side plate 12 to enable the two elastic outer expansion plates 13 to move away from each other The buckle 15 is provided with a liquid matrix containing capsule 46, the elastic outer expansion plate 13 has a needle 47 acting on the liquid matrix containing capsule 46, the elastic outer expansion plate 13 has a liquid channel 49 connected to the liquid matrix containing capsule 46, the inner side of the elastic outer expansion plate 13 is provided with an angle fixed glue spraying port 51, and the outer side is provided with a caulking glue spraying port 50, the auxiliary laying claw 11 has two spaced guide wheels 19, a trigger device 45 is provided between the two guide wheels 19, the two guide wheels 19 clamp the two sides of the cable installation box 10, the trigger device 45 abuts the side plate 12 and drives the thermal deformation spring sheet 16 to deform so as to push the buckle 15 to move in a direction away from the side plate 12.

[0027] In this embodiment, when using this device, it is necessary to first open a cable hidden groove at a predetermined position of the building, put the cable installation box 10 over the cable, and then clip the buckle 15 on the cable installation box 10 so that the buckle 15 closes the opening of the cable installation box 10 to prevent the cable from escaping from the cable installation box 10.

[0028] The assembled cable installation box 10 is laid in the hidden groove on the building, and the auxiliary laying claws 11 are used to clamp the two guide wheels 19 of the auxiliary laying claws 11 on both sides of the cable installation box 10. The two guide wheels 19 extend into the hidden groove to push the auxiliary laying claws 11 to move along the extension direction of the hidden groove. The auxiliary laying claws 11 squeeze the cable installation box 10 inward to hide the cable installation box 10 in the hidden groove, and as the auxiliary laying claws 11 move, the trigger device 45 abuts against the side plate 12 and drives the thermal deformation spring piece 16 to deform in a direction close to the cable. The thermal deformation spring piece 16 and the buckle 15 jointly clamp the cable and stably support the cable in the middle of the cable installation box 10 to reduce the chance of the cable contacting the wall of the cable installation box 10, thereby improving the vibration isolation effect and better protection performance. When the temperature inside the cable installation box 10 rises, the thermally deformable spring piece 16 itself is deformed by the heat, so that the volume of the inner cavity of the cable installation box 10 increases to improve gas flow and improve the heat dissipation effect. The thermally deformable spring piece 16 itself is provided with a piezoelectric body 60. After the piezoelectric body 60 is energized, it drives the thermally deformable spring piece 16 to actively deform, so as to promote the active flow of air inside the cable installation box 10, and further improve the heat dissipation effect.

[0029] As the buckle 15 moves, the needle 47 on the elastic outer expansion plate 13 acts on the liquid matrix storage capsule 46, and the liquid inside flows to the caulking glue spray port 50 and the angle fixed glue spray port 51 through the liquid channel 49. In this embodiment, the material of the liquid matrix storage capsule 46 itself adopts a highly elastic and anti-corrosive elastic film, and the internal cavity is filled with colloid. For example, the liquid matrix storage capsule 46 can be filled with polyurethane foam glue, and the colloid flows to the outside through the caulking glue spray port 50 to fill the gap between the cable installation box 10 and the inner wall of the hidden groove, which is firmly installed and strengthens the sealing; the colloid flows into the interior of the cable installation box 10 through the angle fixed glue spray port 51, and the insulating colloid fills the gap between the cable and the cable installation box 10 to improve the insulation. The liquid matrix storage capsule 46 can also contain a liquid shock-absorbing matrix for insulating and shock-absorbing the cable, and the use of liquid fluid has better thermal conductivity than air, which is conducive to improving the heat dissipation effect.

[0030] In a specific implementation, the buckle 15 includes a support body 20 and a slider 21. The inner surface of the outer bulge 27 is recessed to form a slide groove 22. The slider 21 is arranged in the slide groove 22. The inner wall of the slide groove 22 has an inner bevel 17. The slider 21 has an outer bevel 18. The support body 20 has a first convex strip 23. The slider 21 has a second convex strip 24. The support body 20 and the slider 21 abut against each other and make the first convex strip 23 and the second convex strip 24 engage with each other.

[0031] Specifically, the elastic outer expansion plate 13 includes a fixed portion 25, an elastic portion 26 and an outer expansion portion 27, the fixed portion 25 is connected to the side plate 12, one end of the elastic portion 26 is connected to the fixed portion 25, and the other end is connected to the outer expansion portion 27, the outer surface of the elastic portion 26 is concave, the inner surface of the elastic portion 26 has U-shaped grooves 28 distributed at intervals, and the outer surface of the outer expansion portion 27 is provided with anti-slip barbs 29.

[0032] In this embodiment, the colloid flows into the U-shaped groove 28 through the angle-fixed glue spraying port 51 . When the colloid solidifies, it fills the U-shaped groove 28 , so that the angle of the elastic outer expansion plate 13 is fixed.

[0033] Preferably, the cross-section of the heat-deformable spring piece 16 is arc-shaped, the inner wall of the cable installation box 10 is recessed to form an installation groove, the end of the heat-deformable spring piece 16 is movably inserted into the installation groove, and the heat-deformable spring piece 16 has two stable states, namely a first state protruding toward the side panel 12 and a second state protruding away from the side panel 12 and toward the cable.

[0034] In this embodiment, in the default state, the thermally deformable spring clip 16 is in the first state, at which time the space between the thermally deformable spring clip 16 and the buckle 15 is relatively large, and the cable exists between the two and can move freely; when the trigger device 45 drives the thermally deformable spring clip 16 to deform itself, the thermally deformable spring clip 16 deforms in the direction close to the cable and finally becomes the second state, at which time the thermally deformable spring clip 16 abuts against the cable and clamps the main cable together with the buckle 15.

[0035] Preferably, an electromagnetic generator and a control unit are provided in the trigger device 45, a magnet is provided on the arc-shaped thermally deformable spring 16, and the output end of the control unit is electrically connected to the electromagnetic generator to control the electromagnetic generator to generate a repulsive or attractive force toward the magnet.

[0036] In this embodiment, the control unit is started to control the electromagnetic generator to generate magnetic force, and the magnet is subjected to repulsive force, pushing the thermally deformable spring piece 16 from the first state to the second state. When the cable needs to be removed, the control unit controls the electromagnetic generator to generate magnetic force, and the magnet is subjected to mutual attraction force, driving the thermally deformable spring piece 16 to return to the first state, thereby loosening the cable.

[0037] Preferably, the auxiliary paving claw 11 includes a frame, and limiting height rings 30 are arranged at both ends of the frame. The guide wheel 19 rotates freely at both ends of the frame, and the limiting height ring 30 rotates with damping on the frame. The outer circumference of the limiting height ring 30 is distributed with height limiting blocks 31 of different thicknesses for abutting the side plates 12.

[0038] In this embodiment, as the auxiliary paving claw 11 moves on the side panel 12, the height limiting block 31 of the height limiting ring 30 abuts against the surface of the side panel 12 to limit the depth of the guide wheel extending into the hidden groove on the building body. The height limiting block 31 is rotated to adjust the height limiting blocks 31 of different thicknesses to abut against the side panel 12, thereby adjusting the depth of the guide wheel sinking into the hidden groove.

[0039] Preferably, the inner wall of the height limiting ring 30 is concave to form a locking groove 32, and the frame has a limiting shaft 33 extending into the height limiting ring 30, and the height limiting ring 30 rotates on the limiting shaft 33. The outer periphery of the limiting shaft 33 is provided with an elastic locking strip 34, and the elastic locking strip 34 is locked in the locking groove 32.

[0040] In this embodiment, as the height limiting ring 30 rotates relative to the limiting shaft, the elastic clip 34 can be locked in different locking grooves 32 to achieve angular positioning of the height limiting ring 30 so that the height limiting blocks 31 of different thicknesses are limited to a preset angle.

[0041] Preferably, a plurality of circumferentially distributed expansion strips 35 with air cavities are installed on the inner wall of the guide wheel, a plurality of first gas channels connected one-to-one with the expansion strips 35 are provided inside the guide wheel, a plurality of annularly distributed air holes 36 are provided at the center of the guide wheel, the air holes 36 are connected one-to-one with the first gas channels, both ends of the auxiliary laying claw 11 have height limiting rings 30 that rotate relative to the guide wheel, the height limiting rings 30 have second gas channels corresponding to the air holes 36, and the auxiliary laying claw 11 has an inflation device 37, and the inflation device 37 is connected to the second gas channel.

[0042] In this embodiment, the inner wall of the guide wheel is recessed to form a strip groove, and the expansion strip 35 is an elastic membrane arranged in the strip groove. In the default state, the elastic membrane is hidden in the inner wall surface of the guide wheel. As the guide wheel rotates, when the vent hole 36 is connected to the second gas channel, the elastic membrane is affected by the high-pressure gas, expands itself and protrudes out of the inside of the guide wheel to avoid abutting against the cable installation box 10, thereby increasing friction.

[0043] During specific implementation, two symmetrical arc-shaped grooves are provided on the height limiting ring 30, namely a positive pressure groove 38 and a pressure relief groove 39. The positive pressure groove 38 is connected to the second gas channel, and the pressure relief groove 39 is connected to the atmosphere. The line connecting the center of the height limiting ring 30 and the contact point of the side plate 12 is positioned as a dividing line 40, and the positive pressure groove 38 and the pressure relief groove 39 are respectively located on both sides of the dividing line 40. The guide wheel rolls into the hidden groove, and with the cutting line as the boundary, the side where the guide wheel rotates to enter the hidden groove is the positive pressure side 41, and the other side is the pressure relief side 42, wherein the positive pressure groove 38 is located on the positive pressure side 41, and the pressure relief groove 39 is located on the pressure relief side 42.

[0044] With the above design, as the guide wheel rolls, when the expansion strip 35 on the guide wheel is on the positive pressure side 41, it expands itself and squeezes the cable installation box 10, squeezing the cable installation box 10 into the hidden groove. When the expansion strip 35 rotates to the pressure relief side 42, the gas in the expansion strip 35 leaks out, and the expansion strip 35 itself does not contact the cable installation box 10, and the friction between the two is lost, thereby preventing the guide wheel from re-lifting the already pressed-in cable installation box 10.

[0045] Preferably, a cutting blade 43 is provided on the edge of the guide wheel 19, a power motor 44 and a transmission mechanism are provided on the frame, the shaft of the power motor 44 is connected to the transmission mechanism, and the transmission mechanism is connected to the shafts of the guide wheels on both sides.

[0046] In this embodiment, when the cable installation box 10 needs to be removed, the power motor 44 is started and drives the guide wheels 19 on both sides to rotate through the transmission mechanism. The cutting blade 43 of the guide wheel itself cuts the wall to peel off the filler on both sides of the cable installation box 10 to facilitate the removal of the cable installation box 10.

[0047] Embodiment 2: Most of the technical features of this embodiment are consistent with those of Embodiment 1, except that: The thermally deformable spring piece 16 is an elastic expansion membrane disposed on the side plate 12 . The elastic expansion membrane and the side plate 12 are combined to form an elastic sealing cavity for accommodating inert gas.

[0048] Preferably, the trigger device 45 includes an air pump, an inflation nozzle, a gas tank and a switch valve, the inflation nozzle is connected to the gas tank, and the switch valve is arranged in the inflation nozzle, the inflation nozzle is used to connect to the valve nozzle, and the air pump is connected to the gas tank to replenish high-pressure gas into the gas tank.

[0049] In this embodiment, the trigger device 45 moves to the specified position, the inflation nozzle is connected to the valve nozzle, the switch valve is started, the high-pressure inert gas in the gas tank is replenished into the elastic sealing cavity, and the elastic expansion membrane itself expands and abuts against the cable, thereby stabilizing the cable. In addition, since the elastic sealing cavity is filled with inert gas, it is beneficial to isolate external combustible materials. When the cable heats up and catches fire, the elastic expansion membrane is burned, and the internal high-pressure inert gas can be instantly sprayed out to isolate the combustible gas, thereby protecting the building.

[0050] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
