[0026] The utility model embodiment provides a hardware structure of a passive lock, including a passive lock body 1, and a protective shell 2 is arranged outside the passive lock body 1. Figure 1 to Figure 2 The passive lock body 1 is an existing device and is a passive lock commonly used in mines. The model of the passive lock body 1 is not limited in this application. The staff can open all the passive lock bodies 1 inside the mine with one key, which can make it more convenient for the staff to work. The protective shell 2 can provide preliminary protection for the passive lock body 1 to reduce the damage to the passive lock body 1.

[0027] Two mounting plates 9 are fixedly connected to the outer surface of the passive lock body 1, and a mounting hole 10 is provided on the front of each mounting plate 9. The outer surfaces of the two mounting plates 9 are fixedly connected to the inner wall of the protective shell 2. The passive lock body 1 can be installed to the required position through the mounting plates 9 and the mounting holes 10, which can make it more convenient for the staff to install the passive lock body 1, can achieve the purpose of fixing the passive lock body 1, and can effectively increase the stability of the device.

[0028] A through hole 11 is provided on the front of the protective shell 2, and a closing disk 12 is rotatably connected to the front of the protective shell 2. The through hole 11 can make it more convenient for the staff to open the passive lock body 1. The through hole 11 can be closed by the closing disk 12 to prevent outsiders from causing damage to the passive lock body 1, which can effectively increase the safety of the device.

[0029] A protective mechanism 3 is arranged on the outside of the protective shell 2, and the protective mechanism 3 includes four protective plates 301, and the inner wall of each protective plate 301 is fixedly connected to two slide rails 302, and the inner wall of the slide rail 302 is slidably connected to a first slider 303, and the inner wall of the slide rail 302 is fixedly connected to a first telescopic spring 304, and the other end of the first telescopic spring 304 is fixedly connected to the outer surface of the first slider 303, and the outer surface of the first slider 303 is hinged with a hinge column 305 through a pin shaft, and the other end of the hinge column 305 is hinged to the outer surface of the protective shell 2 through a pin shaft.

[0030] See also Figures 1 to 3 When the protective plate 301 is hit, the protective plate 301 will move, and then the slide rail 302 and the first slider 303 will move, so that the first slider 303 can be driven to slide through the hinge column 305, and the sliding of the first slider 303 will squeeze the first telescopic spring 304, which will cause the first telescopic spring 304 to deform. The deformation of the first telescopic spring 304 can absorb the external impact force, and reduce the damage to the passive lock body 1.

[0031] The outer surface of the first slider 303 is polished, which can reduce the wear caused by the sliding of the first slider 303 and effectively increase the service life of the device. The protective plate 301 is made of a material with higher hardness and can withstand greater impact without breaking, which can effectively increase the safety of the device.

[0032] The inner wall of each slide rail 302 is fixedly connected with a first slide bar 5, and the outer surface of the first slide bar 5 is slidably connected to the inner wall of the first slider 303. The first slide bar 5 can limit the first slider 303 to avoid dislocation of the first slider 303 when sliding, thereby ensuring the normal operation of the device and increasing the safety of the device.

[0033] Four first elastic components 7 are arranged on the outside of the protective shell 2. The two ends of the first elastic components 7 are respectively hinged to the side surfaces of the two protective plates 301 close to each other through pins. The four protective plates 301 can be connected as a whole through the first elastic components 7. When one protective plate 301 is hit, the four protective plates 301 can move at the same time, which can increase the protection effect of the device on the passive lock body 1.

[0034] The inner wall of each protective plate 301 is hinged with two second elastic components 8 through a pin, and the other end of the second elastic component 8 is hinged to the outer surface of the hinge column 305 through a pin. When the second elastic component 8 is deformed, elastic force can be generated, which can make the device better protect the passive lock body 1 and effectively increase the practicability of the device.

[0035] Eight slideways 306 are fixedly connected to the outer surface of the protective shell 2, and a second slider 307 is slidably connected to the inner wall of the slideway 306. A rotating wheel 308 is installed on the outer surface of the second slider 307. The rotating wheel 308 is rotatably connected to the hinge column 305, and a second telescopic spring 309 is arranged inside the slideway 306.

[0036] See also Figure 3 The movement of the hinged column 305 will squeeze the rotating wheel 308, which will cause the rotating wheel 308 to rotate and move. The rotation of the rotating wheel 308 can make the movement of the hinged column 305 smoother. The movement of the rotating wheel 308 can drive the second slider 307 to slide inside the slideway 306, which can drive the second telescopic spring 309 to deform. The deformation of the second telescopic spring 309 can absorb external impacts, which can provide good protection for the passive lock body 1.

[0037] The inner wall of each slide 306 is fixedly connected with a second slide bar 6, and the outer surface of the second slide bar 6 is slidably connected to the inner wall of the second slider 307. The second slider 307 can be guided by the second slide bar 6, so that the slide 306 can slide along the second slide bar 6, and at the same time, the second telescopic spring 309 can be limited to avoid bending of the second telescopic spring 309 during deformation, thereby increasing the stability of the device.

[0038] Four connecting frames 3010 are arranged on the outside of the protective shell 2, and two connecting slide columns 3011 are slidably connected to the inner wall of the connecting frame 3010, and the outer surface of the connecting slide column 3011 is fixedly connected to the outer surface of the second sliding block 307, and two third telescopic springs 3012 are fixedly connected to the inner wall of the connecting frame 3010, and the other end of the third telescopic spring 3012 is fixedly connected to the outer surface of the connecting slide column 3011.

[0039] See also Figures 1 to 4 The movement of the second slider 307 will squeeze the connecting slide column 3011, which will cause the third telescopic spring 3012 to deform. The deformation of the third telescopic spring 3012 can absorb external impact. The device can be connected as a whole through the connecting frame 3010, the connecting slide column 3011 and the third telescopic spring 3012. When one side of the device is hit, the device can move as a whole, and the external impact force can be dispersed to different positions of the device, which can increase the protection effect of the device on the passive lock body 1 and effectively prevent the passive lock body 1 from being damaged.

[0040] Two guide rods 4 are fixedly connected to the inner wall of each connecting frame 3010, and the outer surface of the guide rod 4 is slidably connected to the inner wall of the connecting slide column 3011. The guide rod 4 can limit and guide the connecting slide column 3011, which can make the sliding of the connecting slide column 3011 smoother and avoid displacement of the connecting slide column 3011 during sliding, which can effectively increase the stability of the device.

[0041] Working principle: The device first needs to install the passive lock body 1 on the electronic fence in the mine, which can prevent outsiders from entering the electronic fence to damage the equipment. When the passive lock body 1 needs to be opened, the electronic key can be inserted into the passive lock body 1 through the through hole 11, and then the passive lock body 1 can be opened. When the passive lock body 1 is hit, the protective plate 301 will move, and the movement of the protective plate 301 can drive the slide rail 302 to move, and then the hinge column 305 can push the first slider 303 to slide inside the slide rail 302, and the movement of the first slider 303 can drive the first telescopic spring 304 to deform, and the deformation generated by the deformation of the first telescopic spring 304 The elastic force can absorb the impact force. The movement of the hinged column 305 will squeeze the rotating wheel 308, which can drive the second slider 307 to move. The movement of the second slider 307 can drive the second telescopic spring 309 to deform. The elastic force generated by the deformation of the second telescopic spring 309 can also absorb the impact force. The movement of the second slider 307 will squeeze the connecting sliding column 3011, which will cause the third telescopic spring 3012 to deform. The elastic force generated by the deformation of the third telescopic spring 3012 again absorbs the impact force, thereby protecting the passive lock body 1 and preventing flying gravel from colliding with the passive lock during mining.
