Abstract
The utility model relates to a balance type displacement sensor, which comprises a shell, and a magnet and a reed switch are arranged in the shell, and are respectively movably connected with the shell. When the displacement sensor needs to be used, the magnet and the reed switch are pulled to an appropriate position by straining a first connecting piece and a second connecting piece, at the moment, the contacts of the reed switch are closed under the effect of the magnetic force of the magnet, the sensor is then connected with an alarm device, the relative position between the magnet and thereed switch can be changed when the first connecting piece or the second connecting piece is cut off, torn or broken by other ways, as a result, the magnetic force applied on the reed switch disappears, the closed contacts of the reed switch are opened, and an alarm signal is sent to the alarm device. The sensor increases the precision of the alarm device and reduces the false alarm rate of the alarm device, and moreover, the sensor has the advantages of convenient mounting and low cost, and is worth popularizing and appling.
Description
Technical field
The utility model relates to a kind of balanced type displacement transducer, belongs to electronic technology field.
Background technology
At present, on irregular circumferences such as green house of vegetables, fish pond, orchard, irregular plant area, all be provided with burglar alarm usually, these burglar alarms mainly comprise Infrared Detectors, infrared correlative detector and reveal three kinds of cable fault locators, wherein Infrared Detectors has the advantage highly sensitive, that price is low, but Infrared Detectors has shortcomings such as rate of false alarm height, transmission range be near; Infrared correlative detector rate of false alarm is lower, moderate cost, but the difficulty of construction of infrared correlative detector is big; Reveal cable fault locator and have that rate of false alarm is low, the precision advantages of higher, but revealing cable fault locator costs an arm and a leg, the cost height is not suitable for large scale application.
The utility model content
Problem to be solved in the utility model is at above problem, and a kind of precision height, rate of false alarm is low, easy for installation, cost is low balanced type displacement transducer are provided.
For addressing the above problem, the technical scheme that the utility model adopted is: a kind of balanced type displacement transducer, comprise housing, and be provided with magnet and tongue tube in the described housing, described magnet and tongue tube flexibly connect with housing respectively.
As a kind of prioritization scheme, be provided with first elastic component between one end of described magnet and the housing, the other end is provided with first connector, the other end of described first connector stretches out outside the housing, be provided with second elastic component between one end of described tongue tube and the housing, the other end is connected with second connector, and the other end of described second connector stretches out outside the housing.
A kind of concrete prioritization scheme, described first elastic component is fixedly connected on an end of housing, and described second elastic component is fixedly connected on the other end of housing.
The utility model is taked above technical scheme, have the following advantages: when using, by straining first connector and second connector, magnet and tongue tube are pulled to suitable position, make the contact of tongue tube be in closure state this moment under the effect of magnet magnetic force, then transducer is inserted warning device, when first connector or second connector are cut off, pull and drag or first connector or second connector are disconnected with other modes, the capital changes the relative position between magnet and the tongue tube, the magnetic force that acts on the tongue tube is disappeared, the contact of tongue tube becomes off-state by closure state, send alarm signal to warning device, this transducer has improved the precision of warning device, has reduced the rate of false alarm of warning device, and it is easy for installation, cost is low, is suitable for large scale application.
The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment
Embodiment: as shown in Figure 1, a kind of balanced type displacement transducer, comprise housing 1, be provided with relatively-movable magnet 2 and tongue tube 5 in the housing 1, the right-hand member of magnet 2 is connected with first elastic component 3, and the left end of magnet 2 is connected with first connector 7, and the left end of tongue tube 5 is connected with second elastic component 6, outside being connected with second connector, 4, the first connectors 7 and second connector 4 stretches out housing respectively, the right side of tongue tube 5 is connected with warning device.
First elastic component 3 and second elastic component 6 are spring, and first connector 7 and second connector 4 are connection cord.
When using, by straining first connector 7 and second connector 4, magnet 1 and tongue tube 5 are pulled to suitable position, then transducer is inserted warning device, make the contact of tongue tube 5 be in closure state this moment under the effect of magnet 1 magnetic force, when first connector 7 or second connector 4 are cut off, pull and drag or first connector or second connector are disconnected with other modes, the capital changes the relative position between magnet 1 and the tongue tube 5, the magnetic force that acts on the tongue tube 5 is disappeared, the contact of tongue tube 5 becomes off-state by closure state, sends alarm signal to warning device.
As shown in Figure 2, first connector 7 and second connector 4 are cut off simultaneously, magnet 2 is positioned at the right side of housing 1 under the effect of first elastic component 3, tongue tube 5 is positioned at the left side of housing 1 under the effect of second elastic component 6, the magnetic force that acts on the tongue tube 5 disappears, the contact of tongue tube 5 becomes off-state by closure state, sends alarm signal to warning device.
As shown in Figure 3, second connector 4 is cut off, and tongue tube 5 is positioned at the left side of housing 1 under the effect of second elastic component 6, and the magnetic force that acts on the tongue tube 5 disappears, the contact of tongue tube 5 becomes off-state by closure state, sends alarm signal to warning device.
As shown in Figure 4, first connector 7 is cut off, and magnet 2 is positioned at the right side of housing 1 under the effect of first elastic component 3, and the magnetic force that acts on the tongue tube 5 disappears, the contact of tongue tube 5 becomes off-state by closure state, sends alarm signal to warning device.
