[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8This utility model provides the following technical solution: A portable mine safety device, including a safety device body 1 and a mounting base 2. A locking protrusion 3 is fixedly connected to the side of the safety device body 1. A square rod 4 is inserted into the side of the mounting base 2. A baffle 5 is fixedly connected to one end of the square rod 4. A locking protrusion 6 is fixedly connected to one side of the baffle 5. A spring 7 is fixedly connected to the inner wall of the mounting base 2. An L-shaped rod 8 is fixedly connected to the upper surface of the baffle 5. A rear cover 9 is inserted into the inside of the mounting base 2. A locking seat 10 is fixedly connected to the lower surface of the mounting base 2. A connecting seat 11 is movably connected to the surface of the locking seat 10. A locking protrusion 3 12 is fixedly connected to the lower surface of the locking seat 10. A locking protrusion 4 13 is fixedly connected to the inner top of the connecting seat 11. A spring 2 14 is fixedly connected to the bottom of the connecting seat 11. A base plate 15 is fixedly connected to the lower surface of the connecting seat 11. A strap 16 is fixedly connected to the side of the base plate 15. A Velcro strap 17 is fixedly connected to the surface of the strap 16.

[0027] In this embodiment, the safety device body 1 can be slidably installed into the mounting base 2. The inclined surfaces of the first locking protrusion 3 and the second locking protrusion 6 correspond to each other, making it easier for the first locking protrusion 3 to push the second locking protrusion 6, the baffle 5, and the square rod 4 outward. The first spring 7 can push the baffle 5 to make the second locking protrusion 6 engage with the first locking protrusion 3, thereby preventing the safety device body 1 from sliding out in the opposite direction and improving its stability. By removing the rear cover 9, the safety device body 1 can be quickly separated by continuing to slide. The third locking protrusion 12, by interlacing with the fourth locking protrusion 13, can prevent the mounting base 2 from rotating on its own. By pressing, the mounting base 10 can be moved down, thereby separating the third locking protrusion 12 from the fourth locking protrusion 13. At this time, it is convenient for the mounting base 2 and the safety device body 1 to rotate, so that the angle of the safety device body 1 can be adjusted in time as needed. The second spring 14 is conducive to pushing the mounting base 10 upward, so that the third locking protrusion 12 and the fourth locking protrusion 13 interlaced again, mutually restricting each other and playing a directional role.

[0028] Specifically, the other end of spring 7 is fixedly connected to baffle 5, so that spring 7 can help to lift baffle 5 so that latch 6 can be engaged between latch 3, thus preventing the safety device body 1 from sliding out in the opposite direction.

[0029] Specifically, the mounting base 2 has a slot 18 on its inner side that is compatible with the back cover 9. Magnetic blocks 19 are fixedly connected to the bottom of the slot 18 and the lower surface of the back cover 9. The back cover 9 can be fixed by inserting into the slot 18 so that the magnetic blocks 19 can attract each other.

[0030] Specifically, anti-slip strips 20 are installed on the sides of both the safety device body 1 and the rear cover 9, which facilitates the sliding of the safety device body 1 and the lifting of the rear cover 9.

[0031] Specifically, a groove 21 is provided on the lower surface of the safety device body 1, and a protrusion 22 that matches the groove 21 is fixedly connected to the bottom of the mounting base 2. The groove 21 and the protrusion 22 play a limiting role to prevent the safety device body 1 from sliding off within the mounting base 2. A roller 23 is movably installed inside the protrusion 22. The setting of the roller 23 can reduce the friction between the protrusion 22 and the safety device body 1, making it easier for the safety device body 1 to slide.

[0032] Specifically, the three protrusions 12 and the four protrusions 13 are arranged in an alternating manner, so that the three protrusions 12 and the four protrusions 13 can restrict each other and play a directional role for the card holder 10, the mounting base 2 and the safety device body 1.

[0033] Specifically, the height of spring 14 is greater than the height of the card holder 10, and the top of spring 14 is not connected to the mounting base 2. When the card holder 10 moves down, it can compress spring 14, and spring 14 can push the card holder 10 up to reset.

[0034] The working principle or usage process of this utility model is as follows: When using this utility model, firstly, the mounting base 2 is fixed to the miner's limb by tightening the lower strap 16 and attaching the Velcro 17. Then, the safety device body 1 can be slidably installed into the mounting base 2. Because the inclined surfaces of the first locking protrusion 3 and the second locking protrusion 6 correspond, the first locking protrusion 3 can more easily push the second locking protrusion 6, the baffle 5, and the square rod 4 outwards. The spring 7 can push the baffle 5 to make the second locking protrusion 6 engage with the first locking protrusion 3, thereby preventing the safety device body 1 from sliding out in the opposite direction and improving its stability. The third locking protrusion 12, by intersecting with the fourth locking protrusion 13, can prevent the mounting base 2 from rotating on its own. The device can be moved by pressing down to move the card holder 10 downwards, thereby disengaging the card protrusion 3 12 and card protrusion 4 13. At this time, the mounting base 2 and the safety device body 1 can be adjusted in time as needed. After releasing, the spring 2 14 can push the card holder 10 upwards, causing the card protrusion 3 12 and card protrusion 4 13 to interlock again and restrict each other, playing a directional role. When it is necessary to remove the safety device body 1, simply lift the back cover 9 and continue to slide the safety device body 1 to achieve quick separation. Another way is to push the L-shaped rods 8 on both sides to move towards the middle, so that the L-shaped rods 8 can drive the baffle 5 to move outwards, causing the card protrusion 2 6 to disengage from the card protrusion 1. At this time, the safety device body 1 can be removed by sliding in the opposite direction.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
