Background

The sucking disc handrail, through extruding the air between sucking disc and the adsorption plane, the inside vacuum state that forms of sucking disc, the inside atmospheric pressure of sucking disc is less than external atmospheric pressure this moment, under the effect of external atmospheric pressure, makes the sucking disc handrail be fixed in on the wall. The sucker handrail is popular with the public due to the flexible and simple installation. However, compared with the traditional handrail with holes, the safety performance of the handrail is relatively low, after the sucker handrail is used for a period of time, due to various external factors, the phenomenon of vacuum air leakage inside the sucker is easy to occur, so that the adsorption force of the handrail is reduced and the handrail is not firm any more, and the consequences are unreasonable if the handrail is used under the condition.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2, a sucker handrail with an air leakage alarm device comprises a handrail tube 1, suckers 2 fixed at two ends of the handrail tube 1, a buckle 3 for operating the suckers, and an air leakage alarm device, wherein the air leakage alarm device can comprise two pressure sensors 41, two position sensors 42, a control circuit board 43, a battery 44, an alarm 45, and the like. The pressure sensor 41 is hermetically installed on the suction cup 2 for detecting the degree of vacuum of the suction cup 2. A position sensor 42, a control circuit board 43, a battery 44 and an alarm 45 are installed in the cavity of the handle pipe 1. The pressure sensor 41, the position sensor 42, and the alarm 45 are electrically connected to the control circuit board 43, and the battery 44 supplies power to the control circuit board 43. A position sensor 42 is installed in the vicinity of the buckle 3 for detecting whether the buckle 3 is pressed or opened. Only if the buckles 3 on the two sides are all pressed down, namely the sucker handrail is in a use state, the air leakage alarm device works. That is, the position sensor 42 functions as a power switch of the air leakage alarm device. When clasp 3 is depressed, battery 44 supplies power, and when clasp 3 is open, battery 44 does not supply power. The control circuit board 43 drives the alarm 45 to operate when the pressure sensor 41 detects that the degree of vacuum is less than a preset value (i.e., when air leaks). The control circuit board 43 may be an FPC or a PCB.

Preferably, the pressure sensor 41 is mounted at the center of the suction cup 2 to avoid affecting the tightness of the suction cup 2. The detection head of the pressure sensor 41 should not normally protrude above the surface of the suction plate 2. Preferably, the pressure sensor 41 may be a diaphragm type pressure sensor.

The position sensor 42 may be a contact switch or a proximity switch. When the buckle 3 is pressed down, the position sensor 42 is on, and when the buckle 3 is opened, the position sensor 42 is off; and vice versa.

The alarm 45 may be a buzzer or an audible and visual alarm. Of course, the alarm 45 may also emit a warning voice. Since the alarm 45 is installed in the handle pipe 1, a plurality of sound holes 11 are formed in the handle pipe 1 at positions corresponding to the alarm 45 to allow sound to pass therethrough. The sound outlet holes 11 are usually located inside the handle pipe 1 to prevent foreign materials from entering.

In order to replace the battery conveniently, the handrail tube 1 is provided with a detachable battery bin cover 12. The battery compartment cover 12 is usually located inside the handle tube 1 for aesthetic reasons. The battery 44 may be a button cell or a 7-gauge dry cell battery or the like.

The working principle of the present invention is briefly described as follows: buckle 3 at handrail both ends is pressed, and the sucking disc is in adsorption state, and gas leakage alarm device opens sucking disc pressure monitoring, if detect the inside vacuum of sucking disc under this kind of state and be less than the default, then indicate the sucking disc gas leakage, outside air gets into sucking disc 3 promptly, leads to inside atmospheric pressure value grow (vacuum diminishes), and alarm circuit switches on, and siren 45 sounds to report an emergency and asks for help or increased vigilance. At the moment, the buckle needs to be opened again, the fixed sucker is pressed down by the buckle, the alarm is cut off, and the monitoring operation is continued. Buckle 3 is opened, and sucking disc 2 no longer adsorbs, and the alarm device that leaks gas cuts off the power supply, closes alarming function, and pressure sensor stops the pressure value of monitoring.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
