Description
Technical field
The present invention relates to the secondary means of escape field, particularly a kind of electronic life-saving hamer.
Background technology
When the accidents such as vehicle burst big fire, blast, poison gas, vehicle possibly can't normally be opened car door, because tempered glass of automobile intensity is high, the passenger generally can't smash easily, at this moment just can smash with life-saving hamer the glass of vehicle window.But the life-saving hamer volume is little, and is lightweight, and unbred people is shattered glass easily, causes potential safety hazard.For this reason, need that a kind of volume is little, strength greatly, no matter women, child can use it to smash easily the electronic life-saving hamer of tempered glass of automobile.
Summary of the invention
The present invention is directed to the defective of background technology, proposed a kind of electronic life-saving hamer, can adjust as required the intensity of knocking, do not need too great strength, men and women, old and young all can use, and are not subjected to the restriction of muscle power, and are simple in structure, are fit to promote the use of.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of electronic life-saving hamer, comprise inductance coil, crushing head, retracing spring, iron core, shell, frequency changer circuit, battery pack and switch, wherein inductance coil, retracing spring and iron core are arranged at the inside of shell, one end of described crushing head is taper, the other end passes case head and enters enclosure, and be connected with an end of iron core, this end of described iron core also connects an end of retracing spring, the other end of iron core is fixed with a with it axial vertical iron block, and the other end of described retracing spring is fixed in the inwall of case head; Described inductance coil is wrapped on the iron core, and this inductance coil links to each other with the mouth of frequency changer circuit, and battery pack connects the input end of frequency changer circuit by switch.
As further prioritization scheme of the present invention, described electronic life-saving hamer also comprises damping spring, and described damping spring is positioned at the opposite side that iron block connects iron core, and an end of this damping spring connects iron block, and the other end is fixed on the inwall of shell afterbody.
As further prioritization scheme of the present invention, the outside of described case head is provided with the protection head of at least one projection.
As further prioritization scheme of the present invention, described frequency changer circuit also is connected with the intensity adjustment module of regulating this frequency changer circuit outgoing current.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
The first, employing is battery-powered, easy to use;
The second, electronic life-saving hamer is simple in structure, and reliability is high;
Three, knocking intensity can regulate, and can adapt to the case hardened glass of various thickness, is fit to promote the use of.
Description of drawings
Fig. 1 is electronic life-saving hamer constructional drawing;
Annotate: 1, inductance coil, 2, crushing head, 3, retracing spring, 4, iron core, 5, shell, 6, damping spring, 7, the protection head.
Fig. 2 is electronic life-saving hamer functional-block diagram.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in further detail:
A kind of electronic life-saving hamer, as depicted in figs. 1 and 2, comprise inductance coil 1, crushing head 2, retracing spring 3, iron core 4, shell 5, frequency changer circuit, battery pack and switch, wherein inductance coil 1, retracing spring 3 and iron core 4 are arranged at the inside of shell 5, one end of described crushing head 2 is taper, the other end passes shell 5 heads and enters shell 5 inside, and be connected with an end of iron core 4, this end of described iron core 4 also connects an end of retracing spring 3, the other end of iron core 4 is fixed with a with it axial vertical iron block, and the other end of described retracing spring 3 is fixed in the inwall of shell 5 heads; Described inductance coil 1 is wrapped on the iron core 4, and this inductance coil 1 links to each other with the mouth of frequency changer circuit, and battery pack connects the input end of frequency changer circuit by switch.
Electronic life-saving hamer also comprises damping spring 6; described damping spring 6 is positioned at the opposite side that iron block connects iron core 4; one end of this damping spring 6 connects iron block; the other end is fixed on the inwall of shell 5 afterbodys; the outside of shell 5 heads is provided with the protection 7 of at least one projection; crushing head 2 is hidden in wherein, but actv. protection user.
Retracing spring 3 provides extra elastic force for the shaping head upwards resets, accelerate homing action, damping spring 6 provides reverse elastic force for iron core 4, buffering iron core 4 impulse forces, reduce vibration, the intensity adjustment module is used for regulating the outgoing current of frequency changer circuit, and then intensity is knocked in change, the user can regulate according to oneself body weight and strength, so that faster with glass crushing.Damping spring 6 provides reverse elastic force for iron core 4, and buffering iron core 4 impulse forces reduce vibration.
When needs used electronic life-saving hamer, user's hand electric life-saving hamer was opened switch, battery pack is powered to frequency changer circuit, and frequency changer circuit drives inductance coil 1 with converting direct-current power into alternating-current power.Inductance coil 1 obtains understanding the electromagnetic field that produces high-frequency alternating behind the high-frequency currents, electromagnetic field can drive iron core 4 and produce motion up and down, iron core 4 drives crushing head 2 rapid movement, form hammer action, the user aims at tempered glass of automobile with crushing head 2, and is lower repeatedly knocking fast of crushing head 2, case hardened glass is smashed, realize the purpose of escape, but retracing spring 3 actvies prevent that iron core 4 from can not return to original position in the process of knocking, the progress that impact is knocked.
The above has done detailed description to embodiments of the present invention by reference to the accompanying drawings, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skills possess, can also make a variety of changes under the prerequisite that does not break away from aim of the present invention.
