Abstract

The utility model discloses an earthquake alarm. The utility model is that a pendulum bob which is hung on a bracket is contacted or disconnected with a surrounding conductor block to make that an alarm acoustic circuit is switched on or off. The utility model has the advantages of simple structure, compactness, portability, low cost, practicality and beauty; the earthquake alarm is suitable for the application of various places such as families, offices, shops, recreation grounds, etc.

Description

Earthquake Alarm

The utility model relates to a kind of warning device, the small-sized alarm that reminds people is in time hidden during especially for the generation earthquake.

Seismic energy causes great disaster to the mankind.A lot of ruinous earthquakes are all begun by small earthquakes, in this case, if can in time hide, prevent, just can reduce the loss of a lot of lives and properties.In recent years, seismic activity was comparatively frequent, improved the whole people's the shockproof consciousness of combating a natural disaster, and helped to alleviate the loss that disaster is brought, and ensured people's normal production and living order.

The purpose of this utility model provides a kind of at the blanket small-sized earthquake alarming device of multiple occasion.

The utility model is made of pendulum, conductor block, pallet, support, base and alarm sound circuit, and pendulum is suspended on carriage center, and support overlays on the pallet, and a plurality of conductor block are arranged above the pallet, and conductor block is that the center evenly distributes on same surface level with the pendulum; The conductor block outside is connected with the adjustment screw, and is fixed on the edge of pallet by nut.Be connected with base below the pallet, the alarm sound circuit is arranged in the base, pendulum has lead to be connected with the alarm sound circuit respectively with conductor block.

The utility model is simple in structure, and is small and exquisite nimble, with low cost, both artistic and practical, can be fit to all places with stable environment and use.

Below in conjunction with drawings and embodiments structure of the present utility model is described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the alarm sound circuit theory diagrams.

Embodiment is to cover to put an arch support 8 on round tray 9, support 8 is made of eight arched ribs, the arched ribs lower end distributes uniformly and is connected a week of pallet 9, the upper end collects in culminating point, link together with nut 7, vertical adjustment screw 6 is arranged in the nut 7, vertically adjust screw 6 usefulness flexible cords and hang a conductor pendulum 4, have lead to be connected on the pendulum 4 with the alarm sound circuit; Also be fixed with the horizontal nut that the arched ribs with support 8 is intervally arranged at the edge of pallet 9, be installed with adjusted leveling screws 3 in each nut, the inner termination of adjusted leveling screws 3 has conductor block 11, and conductor block 11 tops have lead to be connected with the alarm sound circuit.There is straight up a pointer 10 at recessed pallet 9 centers, a vertical tube are arranged below the pallet, and vertical tube is located on the base 1, and a universal joint 2 is arranged between pallet 9 and the vertical tube; The alarm sound circuit is housed in the base 1, and the lead on pendulum 4 and the conductor block 11 is connected respectively to A, the B point in the acoustics circuit.During use, alarm is placed on the stability plane, ajusted pallet, make its center pointer align pendulum; Adjust each adjusted leveling screws, conductor block is equated apart from the distance of static pendulum, adjust then and vertically adjust screw, make pendulum and each conductor block be in same plane.Open the power switch on the base, alarm promptly is in suitable state.Pendulum 4 adopts permanent magnet to make, and when earthquake took place, pendulum was flapped toward a certain conductor block, i.e. adhesive is arrived together, and the acoustics circuit power supply is switched on, and then has chimes of doom to sound continuously.Distance between the conductor block of adjusting and the pendulum can be determined the sensitivity of alarm to earthquake magnitude.The utility model can be made exquisite handicraft attractive in appearance and put, and is fit to multiple place such as family, office, shop, public place of entertainment and uses.
