[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a mine safety helmet assembly with a double buffering structure, including a cap body 1, a fixed groove 2 is installed on the outer wall of the cap body 1 by screws, and an adjusting band 4 and a first protective cover 3 are arranged inside the cap body 1, and the first protective cover 3 is arranged above the adjusting band 4;
[0023] A slide cylinder 302 is welded above the first protective cover 3, a first spring 301 is welded inside the slide cylinder 302, a moving rod 303 is welded above the first spring 301, polystyrene foam 304 is glued to the middle of the first protective cover 3, a second protective cover 305 is glued above the moving rod 303, a second spring 306 is glued above the second protective cover 305, and a third protective cover 307 is glued above the second spring 306.
[0024] In this embodiment, as Figure 1 , Figure 2 and 3As shown in the figure, a threaded lead screw 203 is connected to the inside of the fixing groove 2 by internal threads. One side of the threaded lead screw 203 is rotatably connected to a pressing plate 204. One side of the pressing plate 204 is in contact with a headlamp 205. One side of the fixing groove 2 is installed with a locator 202 by screws. Above the locator 202, a photovoltaic panel 201 is connected by a cable. And the pressing plate 204 forms a rotating structure through the threaded lead screw 203. The internal groove of the fixing groove 2 is "U"-shaped. And the size of the internal groove where the pressing plate 204 presses against the fixing groove 2 is consistent with the external structure size of the headlamp 205. Rotate the threaded lead screw 203. The threaded lead screw 203 is consistent with the threaded hole groove on one side of the fixing groove 2. Since the size of the pressing plate 204 is not very large, it can rotate inside the fixing groove 2. The clamping force between the pressing plate 204 and the fixing groove 2 can quickly fix the headlamp 205. Rotate the threaded lead screw 203 in the opposite direction, and the clamping force between the threaded lead screw 203 and the pressing plate 204 disappears, and the headlamp 205 can be taken out. The photovoltaic panel 201 provides electrical energy for the headlamp 205 and the locator 202, which is convenient for using the headlamp 205 for lighting in the dark environment of the mine. The locator 202 (model: KG12) can accurately locate the position of personnel.
[0025] In this embodiment, as Figure 1 and Figure 5 shown, one side of the adjusting belt 4 is adhesively bonded with a pressing buckle 402. One side of the pressing buckle 402 is in contact with a limiting hole 403. One side of the adjusting belt 4 is provided with a buckle 404. One side of the buckle 404 is clamped with an elastic band 401. And a number of limiting holes 403 are arranged horizontally on the surface of the adjusting belt 4. And the internal structure size of the limiting hole 403 is consistent with the external structure size of the pressing buckle 402. The adjusting belt 4 can be adjusted according to the head circumference of the user. The pressing buckle 402 of the adjusting belt 4 is inserted into the limiting hole 403 to adjust the appropriate size to fix the adjusting belt 4 on the head. The elastic band 401 above limits and fixes the head.
[0026] In this embodiment, as Figure 4As shown in the figure, the moving rod 303 forms an elastic structure through the first spring 301; the second protective cover 305 is connected above the moving rod 303. When the second protective cover 305 is impacted and pressed down, it presses down the first spring 301 through the moving rod 303 for buffering. The first spring 301 has the characteristic of elastic deformation. When subjected to an external force, the first spring 301 will deform and store energy. In this process, the work done by the external force is converted into the elastic potential energy of the first spring 301. The deformation of the first spring 301 occurs gradually, which makes the force applied to the object in contact with it not reach the maximum value instantaneously, but increase gradually with the compression or stretching of the first spring 301, thus playing a buffering role and slowing down the instantaneous effect of the impact force. When the external force disappears, the elastic potential energy stored in the first spring 301 will be released, causing the spring to return to its original state and applying a reverse force to the contacting object. This process can also help disperse and weaken the subsequent impact of the impact force, protecting against impacts from ore and stones.
[0027] In this embodiment, as Figure 4 shown, the third protective cover 307 forms an elastic structure through the second spring 306; the second protective cover 305 and the third protective cover 307 are also provided with a sliding cylinder 302 and a moving rod 303. The first spring 301 supports and buffers the impact force driven by foreign objects.
[0028] In this embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, the first protective cover 3, the second protective cover 305 and the third protective cover 307 are vertically distributed, and the sliding cylinder 302 is annularly arranged around the central part of the first protective cover 3; the first protective cover, the second protective cover 305 and the third protective cover 307 are stacked in two layers, and buffer components are provided in both the upper layer and the lower layer to buffer the impact on the cap body 1 when it is impacted by foreign objects simultaneously. Polystyrene foam 304 is provided in the middle of the lower first protective cover 3 and the second protective cover 305. The polystyrene foam 304 has good energy absorption characteristics and can absorb and disperse the impact force by deforming when impacted. The second spring 306 is provided in the middle of the upper second protective cover 305 and the third protective cover 307 to disperse the impact force driven by the impact for buffering.
[0029] In this embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, the internal structure size of the cap body 1 is consistent with the external structure size of the third protective cover 307; the internal structure size of the cap body 1 fits with the third protective cover 307. The three protective covers are all fixed to the cap body 1 by arc-shaped fitting to protect the top of the cap body 1 and prevent the user's head from being injured.
[0030] Usage method and advantages of the present utility model: For the mining safety helmet assembly with a double buffering structure, during use, the working process is as follows:
[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, first, the headlamp 205 is placed between the fixing groove 2 and the pressing plate 204. The threaded lead screw 203 is rotated. The threaded lead screw 203 is threadedly connected to the fixing groove 2, and the pressing plate 204 is fixed to the fixing groove 2. The photovoltaic panel 201 is composed of multiple solar cells. When sunlight shines on the photovoltaic panel 201, the energy of photons is absorbed by the cells, causing the electrons in the cells to gain energy and be excited, forming free electrons and holes. Then, under the action of the internal electric field of the cells, the free electrons move to one end of the cell, and the holes move to the other end, thereby generating current and voltage. The direct current generated by the photovoltaic panel 201 is connected to the headlamp 205 and the locator 202 through wires for power supply. The locator 202 can accurately emit the accurate position. The cap body 1 is worn on the head, and the pressing buckle 402 on the adjustment strap 4 is adjusted so that the hole of the pressing buckle 402 is fixed into the limit hole 403 to adjust the appropriate size. When a stone hits the outside of the cap body 1, the inner moving rod 303 of the first protective cover 3, the second protective cover 305, and the third protective cover 307 moves through the first spring 301 inside the sliding cylinder 302 to disperse the impact force. The second spring 306 and the polystyrene foam 304 in the middle buffer the impact, thereby protecting the head.
[0032] The above shows and describes the basic principles, main features, and advantages of the present utility model. Technical staff in this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
