Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to a safety helmet with a safety alarm structure. Background Technology

[0002] In the current safety helmet market, most helmets primarily focus on providing physical protection, such as impact and puncture resistance, to ensure that the wearer's head is protected in the event of an accident. These traditional safety helmets typically include a helmet body, straps, and other basic structures used to secure the helmet and protect the wearer's head. However, in actual use, workers may not wear the helmet correctly due to negligence or being in a hurry to work, especially failing to properly connect the chin strap, which greatly reduces the helmet's protective effect.

[0003] Currently, some high-end safety helmets on the market may be equipped with electronic alarm systems, but these systems usually require power and cannot function when not powered or when the power is depleted.

[0004] Therefore, to address the above issues, a safety helmet with a safety alarm structure is proposed. When the wearer is active, airflow is generated around them, and the airflow enters the whistle structure to emit a warning sound. This effectively reminds workers to wear the helmet correctly without relying on a power source. Utility Model Content

[0005] In order to overcome the problem that when workers do not wear and connect the chin strap of the helmet correctly during daily work, the alarm cannot be triggered in time, which greatly reduces the protective effect of the helmet.

[0006] The technical solution of this utility model is as follows: a safety helmet with a safety alarm structure, comprising a helmet body, a first strap, a second strap, a connecting component, a contact component, an alarm component, a reset component, a lighting component, and a transmission component. The first strap is located on the inner side of the helmet body, and the second strap is located on the inner side of the helmet body. A connecting component is located at one end of the first strap. A contact component is located on the inner side of the connecting component. The alarm component is located on the inner side of the helmet body, and a reset component is located on the inner side of the connecting component. A lighting component is located on the outer side of the helmet body, and a transmission component is located on the outer side of the helmet body. The connecting component includes a first strap, a second strap, a connecting component, a contact component, an alarm component, a reset component, a lighting component, and a transmission component. The system comprises a connecting frame, a connecting rod, a plug, a locking block, a second connecting frame, a locking groove, a connecting whistle, a connecting pipe, and a flow guide groove. A first connecting frame is attached to one end of a first strap, a connecting rod is attached to one side of the first connecting frame, a plug is attached to one end of the connecting rod, and a locking block is attached to one side of the first connecting frame (two sets of locking blocks are provided). A second connecting frame is attached to one end of a second strap, and a locking groove is provided on the inner side of the second connecting frame (two sets of locking grooves are provided). A connecting whistle is attached to the inner side of the connecting frame, and a connecting pipe is located below the connecting whistle, with the connecting pipe and the connecting whistle communicating with each other. A flow guide groove is provided on the side of the connecting pipe.

[0007] Preferably, by inserting the locking block into the slot of the second connecting frame, the locking block is secured by the slot to connect the first and second connecting frames, forming the chin strap structure of the helmet. When the first and second connecting frames are connected, the connecting rod is inserted into the connecting whistle of the second connecting frame, and the plug blocks the connection between the connecting whistle and the connecting tube, sealing the air intake end of the connecting whistle so that it cannot make a sound. When the worker wears the helmet and does not connect the chin strap correctly, that is, when the plug of the connecting rod does not block the connection between the connecting whistle and the connecting tube, airflow will be generated around the worker when the worker moves. The airflow enters the connecting whistle through the guide groove of the connecting tube, causing the connecting whistle to emit a hissing warning sound. Thus, even when the alarm structure is not powered on, the airflow generated by the worker's movement can be used to sound an alarm when the worker does not wear the helmet correctly.

[0008] Preferably, the contact assembly includes a contact block and a contact switch, with a contact block at one end of the card block, a contact switch on the inner side of the second connecting frame, and a relay below the second connecting frame.

[0009] Preferably, the alarm component includes a first mounting plate and a voice prompt plate. The first mounting plate is provided on the inner side of the helmet body, and the voice prompt plate is provided on one side of the first mounting plate. The voice prompt plate is electrically connected to a relay.

[0010] Preferably, the reset assembly includes a connecting ring and a first connecting block, with the connecting ring located on the outer side of the connecting rod and the first connecting block located on one side of the connecting ring.

[0011] Preferably, the reset assembly further includes a reset spring and a second connecting block. The reset spring is provided on one side of the first connecting block, and the second connecting block is provided on one end of the reset spring. The second connecting block and the locking block are connected to each other.

[0012] Preferably, the lighting assembly includes a second mounting plate and a light, with the second mounting plate located on the outer side of the helmet and a light located on one side of the second mounting plate.

[0013] Preferably, the transmission assembly includes a third mounting plate and a signal transmitter, with the third mounting plate located on the outer side of the helmet and the signal transmitter located on one side of the third mounting plate.

[0014] The beneficial effects of this utility model are:

[0015] By inserting a locking block into the slot of the second connecting frame, the locking block is secured by the slot to connect the first and second connecting frames, forming the chin strap structure of the helmet. When the first and second connecting frames are connected, the connecting rod is inserted into the connecting whistle of the second connecting frame. The plug blocks the connection between the connecting whistle and the connecting tube, sealing the air intake of the connecting whistle and preventing it from emitting a sound. When the worker wears the helmet but does not properly connect the chin strap, i.e., the plug of the connecting rod does not seal the connection between the connecting whistle and the connecting tube, airflow will be generated around the worker when the worker moves. The airflow enters the connecting whistle through the guide groove of the connecting tube, causing the connecting whistle to emit a hissing warning sound. Thus, even when the alarm structure is not powered on, the airflow generated by the worker's movement can be used to sound an alarm when the worker is not wearing the helmet correctly.

The connecting pipe 108 and the connecting whistle 107 are interconnected, and the side of the connecting pipe 108 is provided with a guide groove 109.

[0024] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the contact assembly includes a contact block 201 and a contact switch 202. One end of the locking block 104 is provided with the contact block 201, and the inner side of the second connecting frame 105 is provided with the contact switch 202. A relay 203 is provided below the second connecting frame 105. During use, when the first connecting frame 101 is inserted into the second connecting frame 105, the contact block 201 at one end of the locking block 104 and the contact switch 202 inside the second connecting frame 105 contact each other. The alarm assembly includes a first mounting plate 301 and a voice prompt plate 302. The inner side of the helmet body 1 is provided with a first mounting plate 301 and a voice prompt plate 302. A first mounting plate 301 is provided with a voice prompt board 302 on one side. The voice prompt board 302 is electrically connected to a relay 203. During use, when the chin strap structure is not properly connected by the operator, the contact block 201 and the contact switch 202 are not in contact, the relay 203 changes from normally open to normally closed, the intelligent voice prompt board 302 is powered on, and a voice alarm reminder is given. If the chin strap contact switch is in the closed state, that is, when the user wears the chin strap properly, the relay 203 changes from normally closed to normally open, the voice prompt board 302 loses voltage, and the voice alarm reminder stops.

[0025] The reset assembly includes a connecting ring 401 and a first connecting block 402. The connecting ring 401 is located on the outer side of the connecting rod 102, and the first connecting block 402 is located on one side of the connecting ring 401. The reset assembly also includes a reset spring 403 and a second connecting block 404. The reset spring 403 is located on one side of the first connecting block 402, and the second connecting block 404 is located at one end of the reset spring 403. The second connecting block 404 and the locking block 104 are connected to each other. In use, the reset spring 403 can be used to reset the locking block 104 when it is inserted into the second connecting bracket 105. 403 Reset fixes the card block 104 and the card slot 106. The lighting assembly includes a second mounting plate 501 and a light 502. The second mounting plate 501 is provided on the outer side of the helmet 1, and the light 502 is provided on one side of the second mounting plate 501. The transmission assembly includes a third mounting plate 601 and a signal transmitter 602. The third mounting plate 601 is provided on the outer side of the helmet 1, and the signal transmitter 602 is provided on one side of the third mounting plate 601. In use, the signal transmitter 602 is used to transmit the digital signal converted from the alarm record of the voice alarm to the terminal management device.

[0026] When working, firstly, when the worker wears the helmet correctly, the first connecting frame 101 at the end of the first strap 2 and the second connecting frame 105 at the end of the second strap 3 are connected by a buckle structure. In specific operation, the two sets of locking blocks 104 on the side of the first connecting frame 101 are aligned with the two sets of locking slots 106 on the inside of the second connecting frame 105 and inserted. The elastic force of the return spring 403 makes the locking blocks 104 and the locking slots 106 tightly engage, forming a stable chin strap structure. At this time, the connecting rod 102 on the first connecting frame 101 is inserted into the cavity of the connecting whistle 107 inside the second connecting frame 105. The plug 103 at its end tightly seals the passage between the connecting whistle 107 and the connecting pipe 108, blocking the external airflow from entering the whistle body. At the same time, the contact block 201 at the end of the locking block 104 contacts the contact switch 202 on the inside of the second connecting frame 105, triggering the circuit to conduct a signal.

[0027] If the chin strap is not properly connected, such as if the locking block 104 is not inserted or the engagement is loose, the connecting rod 102 and the plug 103 will not seal the air intake of the connecting whistle 107. When the wearer moves, the ambient airflow enters the connecting pipe 108 through the guide groove 109 and enters the resonant cavity of the connecting whistle 107 along the pipe. The airflow forms a vortex of a specific frequency in the whistle body, producing a hissing sound to attract the attention of people around. This passive whistle alarm does not require power support and is powered by human movement.

[0028] When the electronic system is working normally, if the chin strap is not properly connected, the contact switch 202 will not conduct the circuit, the relay 203 will change from normally open to normally closed, and the intelligent voice prompt board 302 will be powered on to provide a voice alarm reminder. If the chin strap contact switch is in the closed state, that is, when the user wears the chin strap properly, the relay 203 will change from normally closed to normally open, the voice prompt board 302 will lose voltage, and the voice alarm reminder will stop. At the same time, the lighting 502 will automatically turn on the strobe mode to enhance the warning effect. All alarm records are converted into digital signals through the signal transmitter 602 and transmitted to the management terminal.

[0029] Through the above steps, by inserting the locking block 104 into the slot 106 of the second connecting frame 105, the locking block 104 is secured by the slot 106 to connect the first connecting frame 101 and the second connecting frame 105, forming the chin strap structure of the helmet. When the first connecting frame 101 and the second connecting frame 105 are connected, the connecting rod 102 is inserted into the connecting whistle 107 of the second connecting frame 105, and the plug 103 blocks the connection between the connecting whistle 107 and the connecting pipe 108, thus sealing the air intake end of the connecting whistle 107. However, it cannot produce a sound. When the staff wears the helmet but does not properly connect the chin strap, that is, the plug 103 of the connecting rod 102 does not seal the connection between the connecting whistle 107 and the connecting pipe 108. When the staff moves, airflow will be generated around them. The airflow enters the connecting whistle 107 through the guide groove 109 of the connecting pipe 108, causing the connecting whistle 107 to emit a hissing warning sound. Thus, even when the alarm structure is not powered on, the airflow generated by the staff's movement can be used to sound an alarm when the staff does not wear the helmet correctly.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
