Abstract
The utility model relates to a walking stick capable of calling for help automatically. The walking stick comprises a walking stick body and a handrail; an alarm device, an alarm switch and a piezoelectric sensor are arranged on the walking stick body; the alarm switch is arranged on the outer wall of the walking stick body; a power supply is arranged on the handrail; the power supply forms a loop with the alarm device by the alarm switch; the piezoelectric sensor is arranged on the outer wall of the walking stick body; and two electrical connection ends of the piezoelectric sensor are connected with two electrical connection ends of the alarm device respectively. The walking stick body is provided with the piezoelectric sensor, when the walking stick body falls on the ground, the piezoelectric sensor generates voltage to enable the alarm device to work and give an alarm to the outside, a user is assisted to call for help so as to fulfill the function of automatically calling for help.
Description
Technical field
The utility model relates to human body supplemental support instrument, is specifically related to a kind of automatic calling for help crutch.
Background technology
In the life with the crowd of crutch disadvantaged group often; These people meet accident when going out and the probability that oneself can't call for help is also big relatively; If just be not easy to cause danger by the timely attention of people; But traditional crutch only is made up of cane body and handrail, when the user meets accident when not having ability to call for help, does not have auxiliary effect of calling for help.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is to propose a kind of automatic calling for help crutch, and it can assist the user to call for help.
In order to achieve the above object, the technical scheme that the utility model adopted is following:
A kind of automatic calling for help crutch, it comprises cane body and handrail, and the cane body is provided with alarm device, alarm contact and piezoelectric transducer, and alarm contact is positioned on the outer wall of cane body; Handrail is provided with power supply; Power supply forms the loop through alarm contact and alarm device; Piezoelectric transducer is positioned on the outer wall of cane body, and two electric connecting terminals of piezoelectric transducer are connected with two electric connecting terminals of alarm device respectively.
Preferably, said piezoelectric transducer is a circulus, is socketed on the outer wall of cane body.
Preferably, also be provided with power switch on the handrail, power supply is positioned at handrail, and power switch is positioned at an end of handrail, and an end of the other end of handrail and cane body is spirally connected, and power switch, power supply, alarm contact, alarm device are connected in series.One electric connecting terminal of piezoelectric transducer is connected with an electric connecting terminal of alarm device through power switch.Said power supply is dry cell or rechargeable battery.
Preferably, said alarm device is a buzzer, and buzzer is positioned at the cane body.Perhaps, said alarm device is the LED lamp, and the LED lamp is positioned on the outer wall of cane body.Perhaps, said alarm device comprises buzzer and LED lamp, and buzzer is connected in series with the LED lamp, and buzzer is positioned at the cane body, and the LED lamp is positioned on the outer wall of cane body.
The utility model has compared with prior art been installed piezoelectric transducer on the cane body, when the cane body dropped to the ground, piezoelectric transducer produced voltage, makes alarm device work, externally gave the alarm, and auxiliary user calls for help, and realizes the function of automatic calling for help.
Description of drawings
Fig. 1 is the external structure sketch map of the automatic calling for help crutch of the utility model preferred embodiment;
Fig. 2 is the circuit structure block diagram of the automatic calling for help crutch of the utility model preferred embodiment.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
As depicted in figs. 1 and 2, a kind of automatic calling for help crutch, it comprises cane body 1 and handrail 2, cane body 1 is provided with alarm device, alarm contact 4 and piezoelectric transducer 3.
Alarm contact 4 is positioned on the outer wall of cane body 1; Handrail 2 is provided with power supply and power switch 5.
Power supply forms the loop through alarm contact 4 and alarm device; Piezoelectric transducer 3 is positioned on the outer wall of cane body 1, and two electric connecting terminals of piezoelectric transducer 3 are connected with two electric connecting terminals of alarm device respectively.Concrete, said piezoelectric transducer 3 is a circulus, is socketed on the outer wall of cane body 1.Power supply is positioned at handrail 2, and power switch 5 is positioned at an end of handrail 2, and an end of the other end of handrail 2 and cane body 1 is spirally connected, and power switch 5, power supply, alarm contact 4, alarm device are connected in series.One electric connecting terminal of piezoelectric transducer 3 is connected with an electric connecting terminal of alarm device through power switch 5.The power supply of present embodiment can adopt dry cell or rechargeable battery.More concrete, said alarm device comprises buzzer and LED lamp 6, and buzzer is connected in series with LED lamp 6, and buzzer is positioned at cane body 1, and LED lamp 6 is positioned on the outer wall of cane body 1.
Use makes, and with power switch 5 closures, when the user does not feel well, can manually press alarm contact 4, makes buzzer call, 6 flickers of LED lamp; When the user fell in a swoon or falls, piezoelectric transducer 3 contacted with ground, and piezoelectric transducer 3 work produce voltage and make buzzer and 6 work of LED lamp.
In addition, the alarm device of the foregoing description also can be merely buzzer, and buzzer is positioned at the cane body.Perhaps, alarm device can be merely the LED lamp, and the LED lamp is positioned on the outer wall of cane body.The foregoing description also can not be provided with power switch 5.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
