Structure enhances the ability of itself anti-vibration, improves reliable operation performance.
Description of the drawings
Fig. 1 is outer shell construction schematic diagram described in the utility model.
Fig. 2 is inner housing described in the utility model and a support base schematic view of the mounting position.
Fig. 3 is clamping support schematic diagram described in the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word.
As shown in Figure 1, the utility model provides a kind of safety device with frictional vibration monitoring function, including shell
Body, the outer housing are in hollow rectangular shape, vibrating sensor are fixed in the outer housing, for monitoring vibration feelings
Condition.Outer housing is generally fixed in equipment, therefore vibrating sensor is directly in contact with outer housing, can real-time monitor equipment
Vibration Condition.Binding post 11 there are two being set on the outer housing.
Inner housing is additionally provided in the outer housing, be provided in the inner housing 2 control chip, power supply and normally closed type after
Electric appliance, wherein, power supply is connected respectively with control chip and vibrating sensor, is powered for them, controls chip and vibrating sensor
Connection, the vibration signal of vibrating sensor detection pass to control chip, and the control chip is generally selected 51 microcontrollers, controlled
The threshold value of vibration signal is set in coremaking piece, when vibration signal is more than the threshold value, it is normal closing type relay to control chip
Coil power supply, disconnect two contacts of normal closing type relay.Above-mentioned setting is that conventional vibration signal judges that system is set,
By above-mentioned setting, after two contact series of normal closing type relay are linked into main circuit, when the generation for detecting equipment is shaken
When dynamic and vibration signal value is more than given threshold, chip is controlled to make normally closed type relay for the coil power supply of normal closing type relay
Two contacts of device disconnect, and then disconnect main circuit, avoid damaging equipment because vibration is excessive.
As described in Figure 2, the inner housing 2 is in hollow rectangular shape, external to have 8 vertex, in each apex
It is respectively provided with there are one support base 3, the support base is made of rubber material.As shown in figure 3, the support base 3 includes
Vertically arranged first panel 31,32 and the 3rd panel 33 of second panel two-by-two, the first panel 31, second panel 32 and
Three face pastes that three panels 33 are connected respectively with one vertex of inner housing are closed, and are carried out support base 3 and inner housing 2 using glue
It is fixed.
The first panel 31, the outside of 32 and the 3rd panel 33 of second panel are both provided with spring mounting hole, the bullet
Spring 4 is provided in spring mounting hole.One end of spring 4 is contacted with support base 3, and the other end is in contact with the medial surface of outer housing 1,
I.e. each face of inner housing 2 is supported on by four springs 4 on the medial surface of outer housing 1, so that inner housing 2 is in outer housing
In suspension in 1, when outer housing generates vibration, most vibratory impulse is absorbed by spring 4, so that inner casing is in vivo
Component is protected.
