Abstract
The utility model relates to a miniature alarm, which can be conveniently installed in wallets, etc. to make the wallets have theft-proof and alarming function. The drop type alarm is composed of a power supply, a sounder and a sensor, wherein, the sensor is positioned at one end of a spring connected with a switch, and is connected with a hanging chain to carry out sensing operation depending on the gravitational action of the hanging chain. Thus, the utility model has the characteristics of simple structure, reasonable structure, small volume, low cost, flexible configuration, convenient operation, etc.
Description
The utility model relates to a kind of alarm, especially a kind ofly is convenient to carry or is placed in wallet etc., makes it to have micro alarm antitheft, the warning effect.
The stolen problem of money and goods such as wallet causes people's attention for many years as a social concern always.Therefore the patented claim of various antitheft wallets emerges in an endless stream, and the technical scheme of its solution mainly contains drawing-type and touch-induction-type etc.Though the former structure is simpler, because of the other end of connection must be fixed on the clothing, make it to use the inconvenience of wallet connection, and alarm must fixed in position on wallet, purposes is single; Though the latter is to the no connection of taking of wallet, structures such as touch sensor are complicated, and device cost is higher, and uses accidentally, is easy to produce false alarm.Therefore, apply and be restricted.
The purpose of this utility model provides a kind of simple in structure, and is with low cost, easy to make, volume is less, reliable in action, be easy to carry and be not subjected to the bob formula alarm of connection.
Major scheme of the present utility model is: be made up of power supply, acoustical generator and sensor, it is characterized in that described sensor ties up to an end of the spring that links to each other with switch, is connected with one section stretched wire.Wherein, described spring can be a spiral fashion stage clip etc., also can be sheet or thread spring, and described switch can be made into integration with spring, also can be assembled.Described stretched wire generally can adopt the metal pelletron, or loop chain, and chain length is advisable with 5-25 centimetre.When adopting gently thin stretched wire, at the free-end of stretched wire, can be provided with a reinforcing clip, and be provided with the bolt clamping element at the middle part of described reinforcing clip.
Because each chain link got loose each other when the utility model had utilized chain to put more dexterously, to the weightless effect of spring; And when it was lifted from, the stack of the gravity of each chain link made this stretched wire when the free state of being cared for, and still overcame spring force reliably and Closing Switch, implemented to report to the police.Therefore, have simple in structurely, with low cost, volume is little, reliable in action easy to make, be convenient to a end with characteristics, especially stretched wires such as thing configuration such as wallet need not to care for other object, fixing, for the user has brought facility.
Below by embodiment, the utility model is further described.
Accompanying drawing 1 is a kind of structural representation that shows with partial cutaway of the present utility model.
Accompanying drawing 2 is structural representations that another kind of band partial cutaway of the present utility model is shown.
Embodiment 1 integrated package, toggle formula battery and acoustical generator adopt technique known to be connected and are installed in the box body (3), and be provided with the spring (1) (referring to accompanying drawing 1) that is bent into by phosphorus bronze sheet at an end of box body (3), one end of spring links to each other with the anode of power supply, the middle part of spring is connected with stretched wire (4), and the movable end of spring (1) below is provided with a power supply (2) cathode contact, constitute switch (K) thus, switch and spring are united two into one.All above-mentioned devices are arranged in the exquisite box body (3) of design, make stretched wire by being located at the aperture on the box body, outside being suspended at.
During use, box body (3) is placed in the wallet, stretched wire (4) stays outside wallet.At ordinary times, stretched wire (4) dish places in the pocket, to spring and the agravic effect of switch thereof, warning is not worked.When wallet was stolen, each chain link gravity stack of stretched wire (4) made camber of spring, K switch closure, acoustical generator warning work.
Shown in embodiment 2 accompanying drawings 2 is the structural representation of another kind of remodeling of the present utility model.It ties up to and is provided with spring base (10) in the box body (1), is built-in with steel spring (1); Be provided with the switch plate that becomes by the copper sheet punching out in the upper end of spring; Be provided with the bipod that links to each other with power anode or negative electrode respectively in the both sides of spring base (10), constitute switch (K) thus.One end of stretched wire (4) links to each other with the middle part of copper switch plate through connecting link; And the other end of stretched wire is connected with and fixes a reinforcing clip (5).In order to improve the clamping reliability of clip, can be provided with bolt clamping element (6) at the middle part of clamp.All the other structures can with embodiment 1 mutually roughly the same.
During use, reinforcing clip (5) can be sandwiched in the interlayer place of wallet.When needing, swivel bolt clamping element (6) again, it is more solid and reliable to make it clamping, and the box body (3) of the dexterity that links to each other through stretched wire then places outside the wallet.Wallet places in the trousers pocket at ordinary times, and spring is gravitate not, does not work.When oneself takes wallet, only need wallet and stretched wire (4) or box body (3) are together taken out, warning still is in normal condition, does not work.When surreptitiously the person stole wallet, stretched wire under action of gravity (4) compression spring (1) made switch (K) closure, and the acoustical generator buzzer siren is worked at once, thereby has realized aforementioned goal of the invention of the present utility model.
In addition, the appearance of described box body (3) or reinforcing clip (5) can design by requirements such as key card, billboards.
Claims (3)
1, a kind of bob formula alarm is made up of power supply, acoustical generator and sensor, it is characterized in that the end of described sensor at the spring (1) that links to each other with switch (K), is connected with one section stretched wire (4).
2, bob formula alarm as claimed in claim 1 is characterized in that described stretched wire (4) is the employing metallic bond, and chain length is 5-25 centimetre.
3, bob formula alarm as claimed in claim 1 or 2 is characterized in that the free-end of described stretched wire (4) being provided with reinforcing clip (5); The middle part of described reinforcing clip is provided with bolt clamping element (6).
