Abstract
Provided is a key loss responder which comprises a housing, a battery, an alarm device, and a control switch. The battery and the alarm device are both mounted in the housing. A series circuit is formed by the battery, the alarm device, and the control switch through wires. The control switch comprises a pressure sensing metallic sheet and two contact sheets. The two contact sheets are respectively connected with a wire connected with one end of the control switch and do not contact each other. The pressure sensing metallic sheet is fixed over the two contact sheets. When not bearing external force, the pressure sensing metallic sheet is separated from the contact sheets. When bearing external force, the pressure sensing metallic sheet contacts the contact sheets. The key loss responder has beneficial effects of a simple structure, low cost, and very convenient use, resolving a problem of an indiscoverable lost key, timely retrieving the key, and easy popularization and generalization.
Description
Technical field
The utility model relates to a kind of key loss responsor.
Background technology
We are too little unshowy through the worried key of regular meeting, and on the key without any mark and contact method, just how can not find yet be difficult to be found at last when on the way losing yet, and can only join new key at last again even change lock.If the untimely lock that changes if these keys fall in lawless person's the hand, probably can financially cause a significant threat self.
Summary of the invention
The problem that the utility model is difficult to look for after at present key loss has proposed a kind of key loss responsor that can the perception key falls on the ground and give a warning.
Key loss responsor described in the utility model, it is characterized in that: comprise shell, battery, alarm device and gauge tap, described battery, alarm device is installed in described enclosure, described battery, described alarm device, described gauge tap forms series loop by lead, described gauge tap comprises pressure sensitive sheet metal and two contact chips, two described contact chips are connected on the lead of an end that is connected with gauge tap, and two described contact chips do not contact mutually, described pressure sensitive sheet metal is fixed on the top of two described contact chips, and described pressure sensitive sheet metal when not being subjected to external force and described contact chip break away from, when being subjected to external force, described pressure sensitive sheet metal contacts with described contact chip.
Described alarm device is made up of lamp pearl and calling set, and described lamp pearl, described calling set, described battery and the series connection of described gauge tap.
Described battery is miniature button cell.
The deformation time of described pressure sensitive sheet metal is 1 minute.
Described shell is a sphere structure.
During use, when key falls on the ground, the key loss responsor that hangs over key lands simultaneously, and this moment, shell was impacted, and the pressure sensitive sheet metal is subjected to being out of shape after the external force, contact with contact chip then, at this moment, battery, calling set, lamp pearl form path, make that the lamp pearl is luminous, calling set sends alert song simultaneously, reminds the owner of key in time to find; After external force disappeared, the pressure sensitive sheet metal restPosed gradually, and this moment, the metal induction metal plate broke away from contact chip, made whole series loop disconnection, and at this moment, that the lamp pearl stops is luminous, calling set stops sounding.
The beneficial effects of the utility model are: simple in structure, with low cost, to use very conveniently, and indiscoverable problem when having solved key loss is in time given key for change, is easy to popularize.
Description of drawings
Fig. 1 is a skeleton view of the present utility model.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing
With reference to accompanying drawing:
Key loss responsor described in the utility model, comprise shell 1, battery 2, alarm device 3 and gauge tap 4, described battery 2, alarm device 3 is installed in described shell 1 inside, described battery 2, described alarm device 3, described gauge tap 4 forms series loop by lead, described gauge tap 4 comprises pressure sensitive sheet metal 41 and two contact chips 42, two described contact chips 42 are connected on the lead of an end that is connected with gauge tap 4, and two described contact chips 42 do not contact mutually, described pressure sensitive sheet metal 41 is fixed on the top of two described contact chips 42, and described pressure sensitive sheet metal 41 when not being subjected to external force and described contact chip 42 break away from, when being subjected to external force, described pressure sensitive sheet metal 41 contacts with described contact chip 42.
Described alarm device 3 is made up of lamp pearl 31 and calling set 32, and described lamp pearl 31, described calling set 32, described battery 2 and 4 series connection of described gauge tap.
Described battery 2 is miniature button cell.
The deformation time of described pressure sensitive sheet metal 41 is 1 minute.
Described shell 1 is a sphere structure.
During use, when key falls on the ground, the key loss responsor that hangs over key lands simultaneously, and this moment, shell 1 was impacted, and pressure sensitive sheet metal 41 is subjected to being out of shape after the external force, contact with contact chip 42 then, at this moment, battery 2, calling set 32, lamp pearl 31 form path, make that lamp pearl 31 is luminous, calling set 32 sends alert song simultaneously, reminds the owner of key in time to find; After external force disappeared, pressure sensitive sheet metal 41 restPosed gradually, and this moment, metal induction metal plate 41 broke away from contact chip 42, made whole series loop disconnect, and at this moment, that lamp pearl 31 stops is luminous, calling set 32 stops sounding.
The described content of this instructions embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
