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.

[0033] like Figures 1 to 9 As shown, the present invention provides an emergency protection cabinet for abnormal operation of a smart terminal, comprising a cabinet body 1, a pair of cabinet doors 2 are hingedly connected to the front of the cabinet body 1, a blade lock 3 is fixedly installed on the front of the cabinet door 2, a locking component 4 is arranged inside the cabinet body 1, a pair of pulling components 5 are slidably connected inside the cabinet body 1, a pushing component 6 is arranged at the upper end of the cabinet door 2, flaps 7 are hingedly connected at both sides of the cabinet body 1, a main switch 8 is fixedly installed inside the cabinet body 1, and a counterweight block 9 is slidably connected to the upper end of the cabinet body 1;

[0034] The locking assembly 4 includes a sliding card seat 41, a tension spring 42 is fixedly connected to the bottom of the sliding card seat 41, a pair of memory wires 43 are fixedly connected to the top of the sliding card seat 41, a sliding card block 44 is slidably connected inside the cabinet 1, a pair of extrusion plates 45 are movably connected to the upper end of the sliding card block 44, a limited position seat 46 is slidably connected in the middle of the extrusion plate 45, and a pair of springs 47 are arranged in the middle of the limited position seat 46;

[0035] The pulling assembly 5 includes a first slider 51, a first limiting groove 52 is formed on the upper side of the first slider 51, a locking rod 53 is movably connected inside the first limiting groove 52, a pull rod 54 is slidably connected inside the first slider 51, and both ends of the pull rod 54 are fixedly connected to a limiting fork 55 and a handle 56 respectively.

[0036] The above solution is adopted: the memory wire 43 shrinks due to heat, so that the sliding seat 41 is pulled upward to release the engagement between the sliding seat 41 and the blade lock 3, and at the same time, the sliding block 44 is pulled downward to release the limit of the extrusion plate 45, so that the spring 47 is unlocked, and the extrusion plate 45 and the limit fork 55 are pushed to move to both sides, so that the limit fork 55 releases the limit of the locking rod 53, so that the locking rod 53 falls into the first limiting groove 52, and the bottom of the locking rod 53 enters the second limiting groove 62;

[0037] The personnel pulls the handle 56 to move to both sides, so that the limit fork 55 contacts the first slider 51, and then pulls the slide bar 61 to move. At the same time, the first slider 51 will drive the baffle 57 to move, so that the counterweight block 9 releases the limit and falls, and hits the switch of the main switch 8 to turn off the main switch 8. Then the slide bar 61 pushes the cabinet door 2 to flip outward, and the slide bar 61 slides inside the slide groove 63. After the slide bar 61 contacts the limit block 65, the opening process of the cabinet door 2 will stop to prevent the flame from directly rushing out and injuring people. Then continue to increase the force to pull the handle 56, so that the slide bar 61 squeezes and breaks through the limit block 65 and continues to slide inside the slide groove 63, and at the same time continues to push the cabinet door 2 to flip outward, so that the cabinet door 2 is fully opened to extinguish the fire inside the cabinet body 1.

[0038] like Figures 2 to 6As shown, the blade lock 3 is located in the middle of the cabinet door 2 and is on the same horizontal line as the sliding card seat 41. The blade lock 3 is clamped with the sliding card seat 41, and the sliding card seat 41 is slidably connected to the cabinet body 1. The tension spring 42 and the memory wire 43 are both fixedly connected to the cabinet body 1. The sliding card block 44 is located on the upper side of the sliding card seat 41 and is located between a pair of first sliders 51. The memory wire 43 is fixedly connected to the bottom of the sliding card block 44. The extrusion plate 45 is in a shape bent downward from the middle. The extrusion plate 45 is located inside the sliding card block 44 and is movably clamped with the sliding card block 44. The extrusion plate 45 is slidably connected to the two ends of the limit seat 46, and the ends of the extrusion plates 45 that are away from each other are respectively abutted against a limit fork 55. The spring 47 is fixedly connected to the extrusion plate 45, and the spring 47 is in a compressed state. The limit seat 46 is fixedly connected to the cabinet body 1.

[0039] The above scheme is adopted: by setting the blade lock 3 and the sliding card seat 41 to be on the same horizontal line and being engaged with the sliding card seat 41, the cabinet door 2 can be easily locked, the sliding card seat 41 is slidably connected to the cabinet body 1, and a tension spring 42 is set at the bottom of the sliding card seat 41 to keep the sliding card seat 41 stable. The memory metal wire 43 fixedly connected to the top of the sliding card seat 41 can, after shrinking due to heat, pull the sliding card seat 41 to release the engagement with the blade lock 3, and pull the sliding card block 44 downward to release the engagement with the extrusion plate 45, so that the cabinet door 2 can be easily opened. The design of the sliding card block 44 is used to limit and fix the extrusion plate 45, and the extrusion plate 45 is slidably connected to the two ends of the limit seat 46, and is fixedly connected to the spring 47, and the spring 47 is in a compressed state. By respectively contacting the extrusion plate 45 with the limit fork 55, the extrusion plate 45 can squeeze the limit fork 55 to both sides under the push of the spring 47.

[0040] like Figure 4 , Figure 5 and Figure 6 As shown, the pulling assembly 5 also includes a baffle 57, which is fixedly connected to the side of the first slider 51, the baffle 57 is located at the bottom of the counterweight 9, and the lower side of the baffle 57 is the switch of the main switch 8, the baffle 57 is slidably connected to the cabinet 1, the first slider 51 is slidably connected to the inside of the cabinet 1, the first limiting groove 52 passes through the first slider 51, and the shape of the first limiting groove 52 matches the locking rod 53, the limiting fork 55 is locked with the locking rod 53, and the handle 56 is located at one end of the pull rod 54 close to the flap 7.

[0041] The above scheme is adopted: by setting a baffle 57 fixed on the side of the first slider 51, the baffle 57 limits the counterweight 9, and the lower side of the baffle 57 is the switch of the main switch 8. After the baffle 57 moves, the counterweight 9 will fall and hit the switch of the main switch 8 to turn off the main switch 8. The design of the first slider 51 is used to pull the positioning rod 53 and the baffle 57 to move. The pull rod 54 slidably connected in the middle of the first slider 51, and the limit fork 55 and the handle 56 set at both ends of the pull rod 54 can pull the first slider 51 to move by pulling the handle 56. After the extrusion plate 45 pushes the limit fork 55 to move, the handle 56 will push the flap 7 to flip and extend to the outside of the cabinet 1, so that people can pull the pull rod 54 and the first slider 51 through the handle 56.

[0042] like Figure 7 and Figure 8 As shown, the pushing assembly 6 includes a sliding rod 61, one end of which is provided with a second limiting groove 62 and a fixed buckle 64, the upper end of the cabinet door 2 is provided with a sliding groove 63, and a limiting block 65 is fixedly connected inside the sliding groove 63, the sliding rod 61 is slidably connected inside the cabinet door 2, and the end of the sliding rod 61 away from the second limiting groove 62 is slidably connected inside the sliding groove 63, the second limiting groove 62 is located directly below the locking rod 53, the locking rod 53 is movably connected inside the second limiting groove 62, the fixed buckle 64 is locked with the cabinet door 2, the limiting block 65 abuts against the sliding rod 61, and an opening is provided in the middle of the limiting block 65.

[0043] The above scheme is adopted: by opening a second limiting groove 62 on the slide bar 61, and setting the second limiting groove 62 directly below the locking rod 53, it is convenient for the locking rod 53 to enter the second limiting groove 62 and collide with the slide bar 61. The design of the fixed buckle 64 is that the fixed buckle 64 is engaged with the cabinet door 2, so that the slide bar 61 can be fixed inside the cabinet door 2 when not in use. The slide groove 63 opened inside the cabinet door 2 facilitates the sliding of the slide bar 61. The limiting block 65 fixedly connected inside the slide groove 63 can collide with the limiting block 65 when the slide bar 61 moves to the limiting block 65. At the same time, the opening opened in the middle of the limiting block 65 allows the limiting block 65 to be conveniently squeezed and disconnected.

[0044] like Figures 2 to 9 As shown, when the memory wire 43 contracts, the sliding seat 41 is pulled upward to release the engagement between the sliding seat 41 and the blade lock 3, and the sliding block 44 moves downward to release the limit on the squeezing plate 45, and the spring 47 pushes the limit fork 55 to move to both sides through the squeezing plate 45, and the handle 56 pushes the flap 7 to flip and extend to the outside of the cabinet 1.

[0045] The above scheme is adopted: when the memory metal wire 43 contracts, the sliding seat 41 is pulled upward, so that the sliding seat 41 and the blade lock 3 are released, and at the same time, the sliding block 44 moves downward to release the limit on the squeezing plate 45, so that the spring 47 is unlocked, and then the squeezing plate 45 pushes the limit fork 55 to move to both sides, so that the handle 56 pushes the flap 7 to flip and extend to the outside of the cabinet 1.

[0046] like Figures 2 to 9 As shown, after the extrusion plate 45 pushes the limit fork 55 to move, the locking rod 53 falls into the first limit groove 52, and at the same time, the bottom of the locking rod 53 enters the second limit groove 62. At this time, the handle 56 is pulled to move to both sides. At this time, the limit fork 55 conflicts with the first slider 51, and the slide bar 61 is pulled to move by the first slider 51 and the locking rod 53. At the same time, the first slider 51 will drive the baffle 57 to move, so that the counterweight block 9 is released from the limit and falls to conflict with the main switch 8.

[0047] The above scheme is adopted: after the extrusion plate 45 pushes the limit fork 55 to move, the limit fork 55 releases the limit on the locking rod 53, so that the locking rod 53 falls into the first limit groove 52, and at the same time, the bottom of the locking rod 53 enters the second limit groove 62, and then the staff pulls the handle 56 to move to both sides, so that the limit fork 55 conflicts with the first slider 51, and then the slide bar 61 is pulled to move by the first slider 51 and the locking rod 53, and at the same time, the first slider 51 will drive the baffle 57 to move, so that the counterweight block 9 releases the limit and falls to conflict with the main switch 8, and the switch of the main switch 8 is smashed down to turn off the main switch 8.

[0048] like Figures 4 to 9 As shown, when the locking rod 53 moves inside the second limiting groove 62, the sliding rod 61 is squeezed and flipped by the first limiting groove 52. At this time, the locking rod 53 pulls the sliding rod 61 to move, and the sliding rod 61 will push the cabinet door 2 to flip outward while sliding inside the sliding groove 63. After the sliding rod 61 collides with the limiting block 65, continue to pull the handle 56 to make the sliding rod 61 squeeze and break through the limiting block 65 and continue to slide inside the sliding groove 63, while continuing to push the cabinet door 2 to flip outward.

[0049] The above scheme is adopted: when the locking rod 53 moves inside the second limit groove 62, the sliding rod 61 is squeezed and flipped by the locking rod 53. After the locking rod 53 moves to conflict with the sliding rod 61, it will pull the sliding rod 61 to move, so that the sliding rod 61 pushes the cabinet door 2 to flip outward. At the same time, the sliding rod 61 slides inside the sliding groove 63. After the sliding rod 61 conflicts with the limit block 65, continue to increase the force to pull the handle 56, so that the sliding rod 61 squeezes and breaks through the limit block 65 and continues to slide inside the sliding groove 63, while continuing to push the cabinet door 2 to flip outward.

[0050] The working principle and use process of the present invention are as follows: when a fire occurs inside the cabinet 1, the temperature inside the cabinet 1 will rise rapidly, causing the memory metal wire 43 to shrink due to the heat, pulling the sliding seat 41 upward, releasing the engagement between the sliding seat 41 and the blade lock 3, and pulling the sliding block 44 downward to release the limit on the extrusion plate 45, releasing the lock of the spring 47, and then the spring 47 pushes the limit fork 55 to move to both sides through the extrusion plate 45, and the handle 56 pushes the flap 7 to flip and extend to the outside of the cabinet 1, and at the same time, the limit fork 55 releases the limit on the locking rod 53, causing the locking rod 53 to fall into the first limiting groove 52, and the bottom of the locking rod 53 enters the second limiting groove 62;

[0051] Then the personnel pulls the handle 56 to move to both sides, so that the limit fork 55 conflicts with the first slider 51, and then pulls the slide bar 61 to move through the first slider 51 and the locking rod 53. At the same time, the first slider 51 will drive the baffle 57 to move, so that the counterweight block 9 releases the limit and falls to conflict with the main switch 8, and the switch of the main switch 8 is smashed down to turn off the main switch 8. The slide bar 61 then pushes the cabinet door 2 to flip outward, and the slide bar 61 slides inside the slide groove 63. After the slide bar 61 conflicts with the limit block 65, the opening process of the cabinet door 2 will stop to prevent the flame from directly rushing out and injuring people. Then continue to increase the force to pull the handle 56, so that the slide bar 61 squeezes and breaks through the limit block 65 and continues to slide inside the slide groove 63, and at the same time continues to push the cabinet door 2 to flip outward, so that the cabinet door 2 is fully opened to extinguish the fire inside the cabinet body 1.
