Abstract
The utility model relates to a water pressure door opening auto-alarm for general doors and windows in hotel rooms and capable to be used as a flashlight, which is characterized in that the utility model is mainly composed of an alarm part capable to be used as a flashlight, a water pressure pipe plug and a water pressure flexible pipe; when the water pressure flexible pipe is put in the door slot, the internal pressure of the pipe increases so that a steel ball of the water pressure pipe plug bulges; once the door is opened, the internal pressure of the water pipe suddenly decreases, a pressure switch is turned on, and the alarm gives a warning alarm; only when a small round bar is inserted into a small hole on the alarm, the warning alarm stops.
Description
The utility model relates to a kind of automatic alarm, and particularly a kind of hydraulic type automatic alarm that opens the door can be worked as electric torch usefulness, is applicable to general door and window.
Along with modern technologies and growth in the living standard, anti-theft warning device is more and more to be applied to daily life, and volume is little, and is easy to carry, and multi-functional alarm device just arises at the historic moment, and progressively enriches the alarm kind.
The purpose of this utility model is exactly the hydraulic type that will provide a kind of double as electric torch the to use automatic alarm that opens the door.
The technical solution of the utility model is such: it comprises shell, direct supply, alert speaker, pilot lamp, suspender, power switch and alarm circuit, it is characterized in that it also comprises hidden outage aperture, hydraulic pressure switch and hydraulic pressure switch device, above-mentioned other parts are all assembled and are fixed on the shell except that the hydraulic pressure switch device, make it to interconnect by alarm circuit.
The hydraulic pressure switch device is by the penstock plug, hydraulic pressure flexible pipe and steel ball are formed, wherein the hydraulic pressure flexible pipe is connected on the afterbody of penstock plug, and steel ball is arranged in the penstock plug, when the penstock internal pressure increases, steel ball can be ejected in the penstock plug, and pressure diminishes suddenly, and steel ball can set back.
Do detailed description below in conjunction with drawings and Examples:
Fig. 1 is a stereographic map of the present utility model;
Stereographic map when Fig. 2 is the flattening of the utility model hydraulic pressure flexible pipe.
Wherein: 1-direct supply, the hidden outage aperture of 2-, 3-alert speaker, the 4-pilot lamp, the 5-suspender, 6-hydraulic pressure switch, 7-power switch, 8-alarm circuit (not marking among the figure), 9-penstock plug, 10-hydraulic pressure flexible pipe, 11-steel ball, the A-shell, B-hydraulic pressure switch device.
As shown in Figure 1, the utility model is by shell (A), direct supply (1), hidden outage aperture (2), alert speaker (3), pilot lamp (4), suspender (5), hydraulic pressure switch (6), power switch (7) and hydraulic pressure switch device (B) are formed, and connect by alarm circuit.The utility model is hung on the handle for doors and windows by suspender (5), penstock plug (9) is inserted hydraulic pressure switch (6), again hydraulic pressure flexible pipe (10) is placed the door and window seam, door and window is shut, utilized the door and window seam that hydraulic pressure flexible pipe (10) is flattened (as shown in Figure 2), the water pipe internal pressure increases, the interior steel ball of plug (9) is ejected, switch (7) is opened, pilot lamp (4) is bright again, expression electric power abundance.This lamp (4) also can be used as night illumination.
When door and window was opened, the penstock internal pressure diminished suddenly, the penstock reinstatement, and promptly steel ball is got back to original position, and hydraulic pressure switch (6) is connected, and alert speaker is sent the sound.Alarm is stopped, needing to plug little garden rod at aperture (2) and make its outage, because open the door in the dark, the people can't find aperture (2) to make its outage smoothly at short notice, so reach the alarm effect.
Can pull up hydraulic pressure switch device (B) at ordinary times, the utility model promptly can be used as general electric torch, in the time of working as warning horn, derailing switch (B) is plugged again.
In sum, the utility model volume is little, and is simple to operation, has the advantage multi-functional, that cost is low, and once alarm bell sounds, is difficult for found position of cutting off the electricity supply, and strengthened alarm function.
Claims (2)
1, a kind of automatic alarm, it comprises: shell (A), direct supply (1), alert speaker (3), pilot lamp (4), suspender (5), power switch (7) and alarm circuit (8), it is characterized in that it also comprises hidden outage aperture (2), hydraulic pressure switch (6) and hydraulic pressure switch device (B).
2, automatic alarm according to claim 1 is characterized in that hydraulic pressure switch device (B) is by penstock plug (9), and hydraulic pressure flexible pipe (10) and the steel ball (11) that is arranged in the penstock plug are formed.
