Abstract
The utility model discloses a nut anti-theft alarm device, which comprises a fixed plate. One side of the fixed plate is provided with a shell. The inside of the shell is provided with an alarm trigger. The alarm trigger is connected with a contact switch positioned between the shell and the fixed plate. A spring is arranged between the shell and the fixed plate. The nut anti-theft alarm device is also provided with an alarm device connected with the alarm trigger. The utility model adopts the contact-type alarm device. The device is arranged between a nut and a fastening piece to make the nut and the fastening piece clamp the fixed plate and the shell and make the contact switch arranged on the shell in the compressing state, thus, once the nut is loosened, the nut between the fixed plate and the shell can jack up the fixed plate and the shell to make the contact switch bounced so that the alarm trigger is started and a signal is sent to the alarm device to alarm. Therefore, the nut anti-theft alarm device plays a role of preventing burglary and alarming, can also warn the problem that the nut is loosened and avoids causing the potential safety hazard. The nut anti-theft alarm device has the advantages of simple structure, easy implementation and good using effect.
Description
Technical field
The utility model relates to a kind of warning device, especially a kind of nut burglar alarm.
Background technology
At present, the parts of many machineries all are to adopt screw bolt and nut to carry out fastening, for example the fixed mount of automobile spare tire, fuel tank bottom baffle etc. all are to adopt this mode, the advantage of this mode is convenient the installation and dismounting, it is stolen easily that but simultaneous problem is exactly this fastening part, because the dismounting of nut is very simple, so the thief only need back out nut and get final product usually, even can not produce very big vibrations, the general alarm that is equipped with can not start yet, and is difficult to effectively avoid stolen.
Summary of the invention
The purpose of this utility model is: a kind of nut burglar alarm is provided, as long as it will report to the police when nut gets loose at once, can prevent effectively that fastening part is stolen, to overcome the deficiencies in the prior art.
The utility model is achieved in that the nut burglar alarm, comprise fixed head, be provided with shell, in shell, be provided with alarm trigger in a side of fixed head, be connected with the contact switch that is between shell and the fixed head on the alarm trigger, and between shell and fixed head, be provided with spring; And be provided with the warning device that is connected with alarm trigger.
On alarm trigger, be connected with the contact switch that contacts with the inwall of shell.
Contact switch is more than two.
Alarm trigger is wired connection or wireless connections.
Fixed head and shell are cirque structure.
Owing to adopted technique scheme, compared with prior art, the utility model adopts the warning device of contact, this device is installed between nut and the securing member, make nut and securing member be fixedly clamped plate and shell, make the contact switch that is installed on the shell be in impaction state, in case nut loosening, nut between fixed head and the shell just backs down them, and contact switch is upspring, thereby alarm trigger is started, signal is sent to warning device and reports to the police, play the effect of burglar alarm, the problem that also can remind nut loosening simultaneously avoids causing potential safety hazard.The utility model is simple in structure, implements easily, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: the structure of nut burglar alarm as shown in Figure 1, produce the fixed head 1 and the shell 2 of cirque structure, in shell 2, be provided with alarm trigger 3, on alarm trigger 3, be connected with 4 contact switchs 4, wherein two are in shell 2 bottoms, and two other is on the inwall of shell 2; Between shell 2 and fixed head 1, install spring 5; And make a warning device 6(and can adopt devices such as commercially available loudspeaker, display to reequip) with alarm trigger 3 wireless connections.
In use, pass shell 2 and fixed head 1 with bolt 7, the nut 8 of screwing on again makes the top of shell 2 be pressed on the bottom of securing member 9, and nut 8 is fixed plate 1, makes the top of fixed head 1 push down contact switch 4 and the spring 5 that is in shell 2 bottoms.When nut 8 is backed out or is loosening, under the effect of spring 5, fixed head 1 will be backed down downwards, the bottom that breaks away from shell 2, contact switch 4 is upspring, thereby the middle alarm trigger 3 of shell 2 is started, will send a signal in warning device 6 after alarm trigger 3 starts, warning device 6 sends chimes of doom or display alarm prompting.So not only can play antitheft purpose, also can learn the nut loosening of fastening part, in time handle it, avoid bringing potential safety hazard.If the thief thinks to destroy earlier alarm trigger 3; usually can destroy shell 2 earlier; destroy alarm trigger 3 again; so the utility model also inwall of shell 2 is provided with contact switch 4; when being out of shape in case shell 2 is damaged; then can make contact switch 4 pressurizeds and press, to start alarm trigger 3.Quantity is set can formulates according to concrete user demand of contact switch 4, generally at 2～8, this quantitative range is to have optimal result of use and rational production cost.The profile of fixed head 1 and shell 2 can be selected according to the situation of securing member 9, in the present embodiment, fixed head 1 and shell 2 is made as cirque structure, both can conveniently install, and the packing ring that can be used as nut again uses.
