[0002] About half of the earthquakes we experience in our lifetime occur while we are asleep. It is very difficult for people who are asleep to take protective measures quickly and effectively, which is even more dangerous for us to protect human life. Even though mobile phones or televisions can often provide early warning, they cannot always provide early warning. Utility Model Content

[0003] The problem to be solved by the utility model is to provide an early warning device for convenient family use in view of the above-mentioned deficiencies existing in the prior art.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an early warning device, comprising a clock body and a hanging part, the hanging part is fixed on the wall, the lower end of the hanging part is connected to a vertical plate, the upper end of the clock body is connected to a connecting rod, the connecting rod passes through the vertical plate to hang the clock body on the vertical plate, the upper end of the clock body is connected to a first spring, the first spring is connected to a first sphere, the upper end of the first sphere is cut to form a table top, a second sphere is placed on the table top, a groove is provided on the hanging part, the first sphere and the second sphere are located directly above the groove, a horizontal plate is provided in the groove, the horizontal plate is connected to a vertical rod, the vertical rod extends into a blind hole provided at the bottom of the groove, a second spring is wound on the vertical rod, two ends of the second spring are respectively connected to the horizontal plate and the bottom of the groove, a first contact piece is provided on the side of the blind hole, when the second sphere falls on the horizontal plate, the second contact piece provided at the lower end of the vertical rod contacts the first contact piece, and the clock body has a buzzer, and the buzzer connects the second contact piece with the first contact piece.

[0005] Furthermore, the connecting rod is connected with a nut, and the nut and the clock body are located on both sides of the vertical plate.

[0006] Furthermore, the first contact piece and the second contact piece constitute a sliding rheostat in the prior art, a controller is connected between the buzzer and the sliding rheostat, and the sound of the buzzer becomes louder as the second contact piece moves downward.

[0007] Furthermore, when no external force acts on the transverse plate, the lateral distance between the transverse plate and the groove is smaller than the maximum diameter of the second sphere.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model combines the traditional hanging clock with the pendant, and the clock body is hung on the pendant fixed on the wall through the connecting rod through the vertical plate. When an earthquake or the like occurs, the clock body swings around the connecting rod, thereby driving the first spring to move so that the second sphere located on the first sphere falls onto the horizontal plate in the groove. Under the action of gravity, the vertical rod moves downward to make the first contact piece and the second contact piece contact, so that the buzzer sounds.

[0009] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
