Description
Technical field
The present invention relates to a kind of family expenses finishing detecting instrument, be specifically related to a kind of frequency conversion from cavity, tremolo fork floor detector.
Background technology
The ground paving ceramic tile, the wall tiling, finishing has become fashion, finishing has changed people's life, finishing has beautified living environment, give people's Beautiful treat, but have many problems in the finishing implementation process, for the material saving, often packing material is unreal between ground and ceramic tile during such as tiling, stay many empty hidden danger, because lack examination criteria and cheap apparatus, it is very difficult to detect empty hidden danger, so that the householder finds it hard to tell about one's suffering, construction party is but felt reassured and emboldened on account of the support, be further intensified, its harm is: made many rubbish engineerings on the one hand, caused the social resources waste, aggravated on the other hand interpersonal contradiction, affect social harmonious development, so design this detector.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, provides a kind of frequency conversion from cavity, tremolo fork floor detector.
Solution of the present utility model realizes by following technological means: a kind of frequency conversion is from cavity, tremolo fork floor detector, comprise that tuning fork, frequency conversion are from shaking device, sucker, it is characterized in that: frequency conversion tightens up from shaking on device is enclosed within tuning fork by entry the yoke and with screw, and the fork handle of tuning fork is inserted in the dish handle of sucker.
The yoke of described tuning fork can be one or two.
On the fork handle of described tuning fork projection is arranged, the end of fork handle and the diaphragm of sucker connect together, and fork handle can move up and down in the dish handle of sucker.
Described tuning fork can be from vibrations, can knock vibrations with external force, the changing from vibration frequency of tuning fork.
Described frequency conversion is comprised of power supply, variable frequency oscillator, amplifier, loudspeaker, shell, screw from shaking device, has the frequency of the sound wave that entry, loudspeaker send to change on the shell.
Described sucker is comprised of dish handle, dish cover, diaphragm, and is porose on the dish handle.
The diaphragm of described sucker is with fork handle mobile generation deformation in the dish handle.
Described detector is combined with sensor, can detect the cavity size.
Embodiment: frequency conversion is tightened up from shaking on device is enclosed within tuning fork by entry the yoke and with screw, with sucker paster on the ceramic tile of floor or wall, pin on the other hand the sucker cover, one draws the fork handle of tuning fork on hand, make sucker tightly be adsorbed on the ceramic tile, knock the yoke of tuning fork with rubber mallet, the tuning fork vibrations, if between ceramic tile and ground or between ceramic tile and body of wall without the cavity, then can't hear the sound or the sound is very little, if between ceramic tile and ground or between ceramic tile and body of wall the cavity is arranged, can hear the larger sound, thereby in the middle of detecting floor or wall the cavity be arranged, if start frequency conversion from shaking device, tuning fork vibrations and vibration frequency change, and are combined with sensor, can detect the cavity size.
This method detects between ceramic tile and ground or the cavity between ceramic tile and body of wall, and simple, efficient, householder and construction party are reached common understanding easily, are convenient to timely rectification, eliminate empty hidden danger.
Its principle is, tuning fork is subject to knocking very faint of the rear sound that sends, usually only take in one's ear and just listen clearly, but after knocking, by sucker tuning fork is pressed on the ceramic tile, if between ceramic tile and ground or between ceramic tile and body of wall without the cavity, tuning fork and building body can not resonate, so sound is still very weak, if between ceramic tile and ground or between ceramic tile and body of wall the cavity is arranged, there is resonant interaction in this cavity, significantly increased volume, so can hear the larger sound.Frequency conversion is from the loudspeaker sounding that shakes in the device, be actually the cone vibrations of loudspeaker, the vibrations of promotion surrounding air, reciprocity by the power effect, air is to retroaction of cone of loudspeaker, this retroaction, make the tuning fork of miniature deformation vibrations from vibrations, what loudspeaker sent is the sound wave of frequency change, air also just changes to the counteractive frequency of loudspeaker thereupon, and tuning fork is subjected to the retroaction of this frequency change, does forced vibration, the vibration frequency of tuning fork equals the frequency of sound wave that loudspeaker sends, thereby realizes frequency conversion function.The sympathetic response of certain empty big or small corresponding certain frequency sound wave goes out the frequency of sympathetic response sound wave with sensor measurement, knows that just the cavity is big or small.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
