Abstract
The utility model discloses an alarm device of a guide rod, which comprises a power supply, a switch and an alarm which are connected in series, the alarm is a buzzer, the power supply adopts a dry battery, a switch structure comprises a spring, one end of the spring is connected with a negative electrode of the dry battery, the other end is connected with a leading-out wire to connect the buzzer, a positive electrode of the dry battery and a positive electrode connecting piece constitute the switch, when the guide rod is vertically placed, the spring and the negative electrode of the dry battery are positioned at the lower end, and the positive electrode of the dry battery and the positive electrode connecting piece are positioned at the upper end. When the guide rod is vertically placed, the switch is disconnected, so that the buzzer does not alarm; when the guide rod falls onto the ground, the switch is connected. The switch, the alarm and the dry battery are connected in series to form a circuit channel, and the buzzer sends alarm sound to prompt the position of the guide rod to a user, thereby facilitating the user to rapidly find the guide rod.
Description
Technical field
This utility model belongs to electronic technology field, relates to a kind of blind guiding bar alarm device.
Background technology
Common blind guiding bar, owing to there is not a specific alarm device, when blind guiding bar drops to the ground because of carelessness, the searching that user will not stop on the ground brings inconvenience to user.
The utility model content
The technical problems to be solved in the utility model is at the deficiency of existing blind guiding bar, and a kind of blind guiding bar alarm device is provided.
This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of blind guiding bar alarm device is characterized in that, comprises power supply, alarm, spring and by this spring controlled switch, this alarm, switch and power supply all insert in the circuit pathways.
Described power supply is an aneroid battery, spring connects the negative pole of this aneroid battery and is in the lower end of aneroid battery, anode and be arranged on the upper end that positive strap on the blind guiding bar constitutes a switch and is in aneroid battery, when blind guiding bar is vertically placed (or near vertical placement), aneroid battery is because the action of gravity pressuring spring, therefore, the positive pole of aneroid battery does not contact with positive strap, being equivalent to switch disconnects, when blind guiding bar fall down to the ground (be horizontal positioned or near horizontal positioned time), spring does not bear the gravity of aneroid battery basically, and the elastic force of spring promotion aneroid battery makes the positive pole of aneroid battery compress positive strap, thereby connects switch.Switch, alarm and aneroid battery series connection form circuit pathways.
Described alarm is buzzer or loudspeaker or vibrator.
The beneficial effects of the utility model have:
This utility model has been used the gravity characteristic of object and the resiliency characteristics of spring cleverly, with spring and the synthetic switch of dry cell batteries, during switch connection (when blind guiding bar falls down to the ground), then start alarm, the Position Approximate of prompting user blind guiding bar brings very big facility to user.
Description of drawings
Fig. 1 is the overall circuit structural representation of this utility model embodiment 1;
Switch work sketch map when Fig. 2 vertically places for the blind guiding bar of this utility model embodiment 1;
Switch work sketch map when Fig. 3 is the blind guiding bar horizontal positioned of this utility model embodiment 1.
Drawing reference numeral explanation: 1-positive strap, 2-aneroid battery, 3-spring.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
Shown in Fig. 1,2 and 3, the alarm device of this blind guiding bar comprises a power supply, a switch and an alarm series connection, alarm is a buzzer, power supply adopts aneroid battery, construction of switch as shown in Figures 2 and 3, comprise a spring 3, one end of spring 3 connects the negative pole of aneroid battery, the other end connects lead-out wire and connects buzzer, the positive pole of aneroid battery 2 and positive strap 1 constitute switch, when blind guiding bar was vertically placed, the negative pole of spring 3 and aneroid battery 2 was in the lower end, and the positive pole of aneroid battery 2 and positive strap 1 are in the upper end.
Spring 3, aneroid battery 2, positive strap 1 all are arranged in as shown in Figures 2 and 3 the box structure.
The operation principle of this blind guiding bar alarm device is as follows: when blind guiding bar was vertically placed (or near vertical placement), aneroid battery was owing to the action of gravity pressuring spring, therefore, the positive pole of aneroid battery does not contact with positive strap, the switch that is equivalent in Fig. 1 circuit disconnects, and therefore, buzzer is not reported to the police; When blind guiding bar drops on the ground (be horizontal positioned or near horizontal positioned time), spring does not bear the gravity of aneroid battery basically, and the elastic force of spring promotes aneroid battery and makes the positive pole of aneroid battery compress positive strap, thereby connects switch.Switch, alarm (buzzer) and aneroid battery series connection form circuit pathways, and buzzer sends alarm sound, and the position of prompting user blind guiding bar makes things convenient for user to find blind guiding bar rapidly.
Claims (3)
1. a blind guiding bar alarm device is characterized in that, comprises power supply, alarm, spring and by this spring controlled switch, this alarm, switch and power supply all insert in the circuit pathways.
2. blind guiding bar alarm device as claimed in claim 1, it is characterized in that, described power supply is an aneroid battery, spring connects the negative pole of this aneroid battery and is in the lower end of aneroid battery, anode and be arranged on the upper end that positive strap on the blind guiding bar constitutes a switch and is in aneroid battery, described switch, alarm and aneroid battery series connection.
3. blind guiding bar alarm device as claimed in claim 1 or 2 is characterized in that, described alarm is buzzer or loudspeaker or vibrator.
