Abstract

The utility model relates to an outer elastic trigger alarming switch which is characterized in that the inner wall of a metal pipe cylinder is lined with an insulation layer; an opening at the upper end of the metal pipe cylinder is shrunk, and an opening at the lower end of the metal pipe cylinder is connected with a nonmetal end cover; a spring and a metal globe body are arranged in the metal pipe cylinder, and the diameter of the metal globe body is more than that of the upper opening of the metal pipe cylinder; the metal globe body is tightly pushed in the upper opening of the metal pipe cylinder by the spring; the metal pipe cylinder and the spring are respectively connected with a conducting wire joint. The electric switch is matched and connected with various alarms. The switch is arranged on a door leaf or a door frame of a house door, a vehicle door, a safe door, etc., or the switch is arranged at various positions, such as the bottom of a valuable article, etc., and the functions that when the door is opened, the switch gives an alarm, or when the article is moved, the switch gives an alarm, etc. can be realized. The theft behaviors that a thief enters a room, a thief enters a vehicle, a box is opened, an article is moved, etc. are reduced. The utility model promotes the harmony and the stability of a society.

Description

The outer trigger-type alarm switch that plays

Technical field

The utility model relates to a kind of electric switchgear, specifically a kind of outer trigger-type alarm switch that plays.

Technical background

Because the wildness of stealthy activity, the installation of burglar alarm is also more and more general.And daily that what see is exactly the car alarm alarm is more.The warning trigger switch of this class alarm mostly is wireless trigger switches such as the vibration or the sound, and for improving the burglar alarm performance, also has to transfer the sensitivity of trigger switch higher.Though therefore the burglar alarm performance increases, the situation that triggers warning because of misoperation also takes place repeatedly.Typically be exactly that firecracker rings, cause auto alarm in blocks.This has formed not only comparatively that severe noise disturbs residents, and the more important thing is and has also benumbed the car owner simultaneously, makes its vigilant reduction.Though thereby much vehicle has been installed car alarm, loses the car phenomenon and still happens occasionally.

Common electric switch is normally pressed the operator scheme that the back is connected, cocked back disconnects.And the burglar generally needs in the inlet chamber, in the car, promptly illegally opens door (window), car door, chamber door etc. when committing theft, and this is most things that this type of will be done before committing theft.Thereby, if can in time trigger warning during illegal the unlatching when door and window, then can obviously improve the warning performance, draw back the burglar with fear, the generation of reducing the loss.But being burglar alarm, this prerequisite need connect the electric switch that a kind of outer bullet is connected trigger-type.At present owing to there is not this electric switch, and switch in general can not realize that outer bullet connects the mode of operation of triggering, thereby has influenced the normal use of burglar alarm, makes larceny succeed repeatedly.

The utility model content

The purpose of this utility model just provides a kind of outer bullet trigger-type alarm switch that can realize outer bullet connection triggered mode of operation, reaches the generation of stealing cases such as car to suppress burglary effectively, promotes stabilizing with harmonious of society.

The utility model is achieved in that the outer trigger-type alarm switch that plays is that the inwall of the metal pipe barrel that closes up in the upper end is lined with insulating barrier, the lower port of metal pipe barrel is connected to nonmetal end cap, spring and the diameter metal ball body greater than the metal pipe barrel back cut diameter is housed in the metal pipe barrel, metal ball body by spring top clamping in metal pipe barrel suitable for reading; On metal pipe barrel and spring, connect respectively to draw terminal is arranged.This electric switchgear is that to bump pearl with the door leaf that the carpenter uses always be citation form.By in metal pipe barrel, installing the inwall insulating barrier additional, metal ball body is insulated mutually with barrel with spring; By reequiping nonmetal end cap, insulated mutually in the spring and the tube end.Realized thus with metal pipe barrel be a utmost point, with metal ball body and spring electric switch for another utmost point.This electric switch is by the clutch on metal ball body and metal pipe barrel upper brim edge, as the break-make form of electric switch.When the upper portion pressurized of metal ball body, when bouncing back in the metal pipe barrel, electric switch disconnects, and the alarm that is connected is failure to actuate.After the upper pressure of metal ball body disappeared (open as door and window or article are moved away from), metal ball body promptly popped up, and held out against suitable for reading at metal pipe barrel, and electric switch is connected, and can trigger the alarm that is connected, and sends audible alarm.Realized the working method of the outer bullet connection triggering of electric switch thus.This electric switch and various alarms are connected, and be installed on the door leaf or doorframe of room door, car door, safe door etc., perhaps be installed in the bottom equipotential postpone of valuables, can realize open alarm or remove functions such as thing warning, thereby reduce the generation of entering the room, advancing car, unpacking, removing larcenies such as thing, promote stabilizing of society with harmonious.

Description of drawings

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

Fig. 2 is the fundamental diagram that the utility model connects alarm.

Embodiment

As shown in Figure 1, close up in the upper end of metal pipe barrel 2, in order to block metal ball body.The inwall of tiny metal pipe barrel 2 can in apply dielectric film, but thicker metal pipe barrel 2 in the lining plastic bushing, with formation insulating barrier 3.Plastic end cover 5 is screwed in the lower port of metal pipe barrel 2 by screw thread, and the top of the spring 6 in the metal pipe barrel 2 holds out against metal ball body 1, and the spring bottom withstands on the plastic end cover 5.Have central small hole on plastic end cover 5, a line conductor joint penetrates from the hole, and is connected with spring 6 solderings; Another line conductor joint 4 direct solderings are on the outer wall of metal pipe barrel 1.Form two connection electrode of electric switch thus.

For the electric switch of larger volume, preferably be provided with the fixed flat planar 7 with the metal pipe barrel one in the outside suitable for reading of metal pipe barrel 2, in order to electric switch firmly is fixed on door leaf or the doorframe.Both can play door leaf and bump pearl, and have outer bullet again and connect the switch effect that triggers warning.For the electric switch of tiny volume, then can not establish this fixed flat planar, directly electric switch is pressed on the fan or frame that is pressed into door and window, or in the hole of article base.

Though this electric switch realized that outer bullet is connected and triggered the switching function of reporting to the police, then can not trigger warning for the normal unlatching of door and window.For this reason, when using this electric switch, also must additional control switch.As shown in Figure 2, in the electric loop that connects this electric switch T and alarm M, be connected in series a K switch.This K switch can be selected the comparatively hidden switchtypes of form such as pad pasting switch or touching switch for use, is installed in more hidden parts such as door and window.At ordinary times, this K switch disconnects, and alarm M does not work; When needing to set burglar alarm, Closing Switch K, electric switch T promptly starts working, the folding of monitoring door and window or the situations such as displacement of article.

Fit form for metal door and window and metal frame, can strike next pitting at the fan of door and window or the position relative of frame with electric switch, stick adhesive tape or other nonmetal attached layers, form the insulation of metal ball body and door and window contact site thus, thereby prevent the generation of false alarm situation.
