When the alarm 12 sounds, the reel 111 will reel the pull rope 112.

[0036] When the power strip 1 catches fire, the alarm 12 will sound an alarm because the alarm 12 is electrically connected to the electric push rod 13 through the control system. At this time, the telescopic end of the electric push rod 13 will move upward, and the telescopic end of the electric push rod 13 will drive the connecting member 14 to move upward as well. The upward movement of the connecting member 14 will drive the first rack 15 to move upward as well. Because the first rack 15 is meshed with the gear 16, the upward movement of the first rack 15 will drive the gear 16 to rotate inwardly, and the inward rotation of the gear 16 will drive the fixing member 18 to rotate upwardly, and the upward rotation of the fixing member 18 will drive the extrusion plate 110 to rotate upwardly, and the upward rotation of the extrusion plate 110 will drive the anti-slip strip 118 to rotate upwardly as well.

The block on the fixing member 18 rotates upward and is connected to the top of the connecting member 14. The telescopic end of the electric push rod 13 continues to drive the connecting member 14 to move upward. Because the block of the fixing member 18 is connected to the connecting member 14 at this time, the upward movement of the connecting member 14 will drive the moving rod of the fixing member 18 to move upward. The storage spring 116 is extended, and the upward movement of the moving rod of the fixing member 18 will drive the extrusion plate 110 to move upward, and the anti-slip strip 118 will also move upward.

The electrical plug will be pulled out from the socket of the power strip 1 when it moves upward. Because the switch of the alarm 12 is also electrically connected to the reel 111 through the control module, 3 seconds after the alarm 12 sounds, the reel 111 will reel the pull cord 112. At this time, the electric push rod 13 has been working for 3 seconds, and the plug has been pulled out of the power strip 1. The reel 112 will drive the sliding member 113 to move to the right. The movement of the sliding member 113 to the right will pull the telescopic end of the telescopic member 114 to move to the right. The extrusion plate 110 has pulled the electrical plug out of the power strip 1. The telescopic end of the telescopic member 114 continues to move to the right and finally moves to completely seal the square door above the storage box 11. Because one of the necessary conditions for combustion is oxygen, the telescopic member 114 will store oxygen in the storage box 11. The external air is isolated from the external oxygen, and the burning socket 1 will stop burning due to lack of oxygen. When the fire of the socket 1 is extinguished, the alarm 12 detects that the fire extinguishing is completed and stops sounding the alarm. Because the alarm 12 is electrically connected to the electric push rod 13 through the control module system, the telescopic end of the electric push rod 13 will move downward, and the telescopic end of the electric push rod 13 will drive the connecting piece 14 to move downward. The connecting piece 14 no longer squeezes the block of the fixing piece 18. At this time, the extended force storage spring 116 will shrink. The contraction of the force storage spring 116 will drive the moving rod of the fixing piece 18 to move downward, thereby driving the electrical plug to move downward. The downward movement of the connecting piece 14 will also drive the rack 15 to move downward. The downward movement of the rack 15 will drive the gear 16 to rotate outward.The gear 16 rotates outward to drive the fixing member 18 to rotate downward, and the fixing member 18 rotates so that the anti-slip strip 118 also rotates downward. The anti-slip strip 118 rotates downward to disengage from the plug, and the plug falls onto the telescopic member 114 pulled to the right. At this time, the compressed pressure spring 19 extends, and the extension of the pressure spring 19 drives the extrusion plate 110 to extend. The fixing member 18 rotates downward to reset, and the fixing member 19 and the extrusion plate 110 rotate downward to reset. When someone observes the device that has completed fire extinguishing, people can remove the plug from the telescopic member 114, and the alarm 12 no longer sounds an alarm. , the reel 111 will not continue to reel the pull cord 112, the staff can move the sliding member 113 to the left, the sliding member 113 moving to the left will drive the telescopic end of the telescopic member 114 to move to the left, the pull cord 112 is pulled out from the reel 111, after the telescopic end of the telescopic member 114 moves to the left and resets, people can check and clean the power strip that has been extinguished. Through the above operation, when the power strip 1 catches fire, the plug of the electrical appliance can be quickly unplugged to achieve the purpose of protecting the electrical appliance, and the storage box 11 is isolated from the outside air by the telescopic member 114 to extinguish the fire of the power strip 1. ,

[0037] Embodiment 2: Based on embodiment 1, Figure 5-Figure 8 As shown, it also includes a pushing mechanism for pushing away objects around the power strip 1, and the pushing mechanism includes a blocking rod 2, a fixed block 21, a linear spring 22, a guide block 23, a sliding rod 24, a blocking plate 25, a guide column 26, a coil spring 27, a guide member 28 and a triangular block 29.

[0038] When the power strip 1 catches fire, the temperature around the power strip 1 will increase, which can easily ignite objects placed around the power strip 1 and cause a fire. As mentioned above, when the power strip 1 catches fire, the connecting piece 14 will move upward, and the upward movement of the connecting piece 14 will drive the first rack 15 to move upward. The upward movement of the first rack 15 will block the rod 2 from moving upward, and the upward movement of the blocking rod 2 will squeeze the inclined surface of the guide block 23, and the guide block 23 will move in a direction close to the fixed block 21, and the guide block 23 will drive the sliding rod 24 to move in a direction close to the fixed block 21. The movement of the sliding rod 24 will be pulled out of the blocking plate 25, and the sliding rod 24 will no longer restrict the blocking plate 25. At this time, the coil spring 27, which was originally in a compressed state, will extend, and the extension of the coil spring 27 will drive the guide piece 28 to move upward, and the upward movement of the guide piece 28 will squeeze the triangular block 29. Under the squeezing action of the triangular block 29, the guide The guide member 28 will move outward, the guide member 28 will move both upward and outward, the guide member 28 will drive the blocking plate 25 to move both upward and outward, the movement of the blocking plate 25 will push the objects around the storage box 11 away from the storage box 11, after the fire is extinguished, the rack 15 will move downward and reset, the blocking rod 2 will also move downward and reset, the blocking rod 2 will no longer squeeze the guide block 23, at this time the linear spring 22 is in an extended state, people need to move the blocking plate 25 downward and inward to reset, the blocking plate 25 will drive the guide member 28 to move inward and downward to reset, the extended coil spring 27 will be compressed again, people need to insert the sliding rod 24 into the blocking plate 25 to limit the blocking plate 25, in this way, the distance between the burning power strip 1 and the surrounding objects can be increased, the surrounding objects can be better isolated from the power strip 1, and the surrounding objects can be prevented from being ignited.

[0039] like Fig. 9 and Fig.10 As shown, it also includes a trigger mechanism for turning off the power of the power strip 1, and the trigger mechanism includes an extrusion block 3, a pressing piece 31, a fixed plate 32 and a reset spring 33. The extrusion block 3 is fixedly connected to the bottom of the telescopic end of the telescopic piece 114, and inclined surfaces are arranged on the left and right sides of the extrusion block 3. The fixed plate 32 is fixedly connected between the front and rear inner sides of the storage box 11, and the pressing piece 31 is slidably connected to the fixed plate 32. The pressing piece 31 is pressed and matched with the power button of the power strip 1. The reset spring 33 is wound on the pressing piece 31, and one end of the reset spring 33 is fixedly connected to the pressing piece 31, and the other end of the reset spring 33 is fixedly connected to the fixed plate 32. The inclined surface of the extrusion block 3 is pressed and matched with the pressing piece 31.

[0040] When the socket 1 catches fire, it is necessary to cut off the power supply in time. If the power supply continues to be energized when the socket 1 catches fire, electric arcs and high temperatures will be generated, which may easily cause electric shocks to people around and cause serious harm to people and objects around. As mentioned above, the telescopic end of the telescopic member 114 will move to the right to seal the square door above the storage box 11, and the telescopic end of the connecting member 14 will move to the right, which will drive the extrusion block 3 to move to the right. During the movement of the extrusion block 3 to the right, the inclined surface on the right side of the extrusion block 3 will squeeze the pressing member 31. Under the extrusion action of the extrusion block 3, the pressing member 31 will move downward. The downward movement of the pressing member 31 will press the power button of the socket 1, so that the socket 1 is powered off. When the pressing member 31 is pressed, the power button of the socket 1 is pressed. During the downward movement of 31, the reset spring 33 will extend. As mentioned above, after the fire is extinguished, the telescopic end of the telescopic member 114 will move to the left and reset. When the telescopic end of the telescopic member 114 moves to the left, it will drive the extrusion block 3 to move to the left and reset. During the movement of the extrusion block 3 to the left, the inclined surface on the left side of the extrusion block 3 will squeeze the pressing member 31 downward, and the pressing member 31 will move downward, and the reset spring 33 will be compressed again. Because the power strip has been burned out at this time, the pressing member 31 cannot turn on the power switch of the power strip when it moves downward. In this way, the power switch of the power strip 1 can be turned off while the fire is being extinguished, so as to better protect the surrounding people and objects.

[0041] like Fig.11 and Fig.12 As shown, a lifting mechanism for lifting the storage box 11 is also included, and the lifting mechanism includes a second rack 4, a connecting frame 41, a support frame 42 and a guide rod 43.

The connecting frames 41 are fixedly connected to the right side of the support frame 42, and the second racks 4 are fixedly connected to the left side of the connecting frame 41. The second rack 4 is meshed with the gear 16.

[0042] When the power strip 1 inside the storage box 11 catches fire, the temperature at the bottom of the storage box 11 will be very high. In daily life, the power strip 1 is often placed on flammable objects such as sofas and quilts. The high temperature at the bottom of the storage box 11 will ignite these flammable objects and cause a fire. Therefore, a lifting mechanism is required to isolate the storage box 11 from the objects at the bottom of the storage box 11. As mentioned above, when the power strip 1 catches fire, the telescopic rod of the electric push rod 13 will extend. The extension of the telescopic rod of the electric push rod 13 will drive the connecting member 14 to move upward, so that the gear 16 will rotate inwardly. The inward rotation of the gear 16 will drive the second rack 4 to move downward. The downward movement of the second rack 4 will drive the connecting frame 41 to move downward. The downward movement of the connecting frame 41 will drive the supporting frame 42 to move downward relative to the guide rod 43. The guide rod 43 will move upward relative to the support frame 42, and the upward movement of the guide rod 43 will drive the storage box 11 to move upward as well. As mentioned above, after the fire of the power strip is extinguished, the connecting piece 14 will move downward to cause the gear 16 to rotate outward, and the outward rotation of the gear 16 will drive the first rack 4 to move upward and reset. The upward movement of the first rack 4 will drive the connecting rod 41 and the connecting plate 42 to move upward, and the guide rod 43 will move downward relative to the support frame 42, and the downward movement of the guide rod 43 will drive the storage box 11 to move downward and reset.
