Abstract
A kind of Self-adsorptive type sensor fixed device, it comprises sensor, corrugated vacuum sucker, supporting tube, back-moving spring and seal chamber; Described sensor is fixed on the upper end of supporting tube, and the end face for accepting physical state information on sensor exposes and a little more than the end face of corrugated vacuum sucker; Seal chamber is fixed on the bottom of corrugated vacuum sucker, communicates between the two; Supporting tube is arranged in corrugated vacuum sucker, and the bottom of it and corrugated vacuum sucker is for being slidably matched.Sensor can be fixed on the measured object surface of shell of any material by the present invention quickly and easily, and has very high reliability.
Description
Technical field
The present invention relates to a kind of device that can be fixed on by sensor easily on any material measured object surface of shell, belong to detection technique field.
Background technology
Many physical state detection sensors obtain signal from measured object surface, and this sensor must be fixed on measured object on the surface in use.At present, the state detection sensor fixing means generally adopted both at home and abroad mainly contains two kinds, and one is mechanical means, and one is magnetic suck fixed form.Mechanical means comprises that screw clamp is fixed, bandage is fixing, and this fixing means operation is very loaded down with trivial details, inefficiency, and is difficult to ensure that sensor and measured object intimate surface are fitted, and reliability is poor.Magnetic suck fixed form utilizes magnetic force that sensor is adsorbed on measured object surface, this fixing means simple and fast, reliability is high, but is only applicable to the measured object of magnetic material housing, the aluminum hull that equipment extensively adopts, stainless steel case, plastic housing then cannot be installed, and the scope of application is less.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Self-adsorptive type sensor fixed device that can be fixed on by sensor easily on the measured object surface of shell of any material is provided.
Problem of the present invention realizes with following technical proposals:
A kind of Self-adsorptive type sensor fixed device, it comprises sensor, corrugated vacuum sucker, supporting tube and seal chamber; Described sensor is fixed on the upper end of supporting tube, and the end face for accepting physical state information on sensor exposes and a little more than the end face of corrugated vacuum sucker; Seal chamber is fixed on the bottom of corrugated vacuum sucker, communicates between the two; Supporting tube is arranged in corrugated vacuum sucker, and the bottom of it and corrugated vacuum sucker is for being slidably matched.
Above-mentioned Self-adsorptive type sensor fixed device, sets up back-moving spring and arrange sliding sleeve between corrugated vacuum sucker and supporting tube; Described sliding sleeve is tubular, is fixed on the bottom of corrugated vacuum sucker; Described supporting tube to insert in sliding sleeve and and be slidably matched between sliding sleeve; Described back-moving spring is sleeved on supporting tube, its one end and sensor contacts, and other end top is pressed on sliding sleeve.
Above-mentioned Self-adsorptive type sensor fixed device, described supporting tube is hollow tubular, and described seal chamber is provided with signal output terminal, the signal transmssion line of described sensor through after supporting tube with signal output part sub-connection.
Above-mentioned Self-adsorptive type sensor fixed device, arranges capping at the afterbody of seal chamber.
The present invention is by corrugated vacuum sucker, supporting tube, cooperatively interacting between back-moving spring and sliding sleeve, sensor stabilization is pressed at testee on the surface, make to remain constant pressure between sensor and testee surface, thus signal transmission has very high reliability.Use corrugated vacuum sucker to provide absorption affinity, the various interference introduced from testee can be completely cut off preferably, improve the signal to noise ratio (S/N ratio) of sensor.Sliding sleeve is set between corrugated vacuum sucker and supporting tube, except the compression travel needs that can meet corrugated vacuum sucker, also can, by sensor definition in the central authorities at corrugated vacuum sucker, be conducive to avoiding the asymmetric of various undesired signal.In addition, this device is easy to operate, quick, not only can increase work efficiency, and not by the restriction of measured object shell material, applied widely.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention.
In figure, each label is: 1, sensor, 2, supporting tube, 3, back-moving spring, 4, sliding sleeve, 5, spacing back-up ring, 6, corrugated vacuum sucker, 7, seal chamber, 8, signal output terminal, 9, capping.
Embodiment
Referring to Fig. 1, the sensor 1 for input is fixed to the upper end of supporting tube 2; The back-moving spring 3 of supporting tube 2, overcoat matches with sliding sleeve 4, forms moving part; Spacing back-up ring 5 pairs of supporting tubes 2 carry out spacing, prevent supporting tube 2 from extracting out in sliding sleeve 4 under the effect of back-moving spring 3; Corrugated vacuum sucker 6 is fixed on seal chamber 7 by sliding sleeve 4.Signal transmssion line guides to signal output terminal 8 through supporting tube 2.End face signal detection sensor accepting physical state information exposes and a little more than the end face of corrugated vacuum sucker 6.
The principle of work of this device: during use, corrugated vacuum sucker 6 aimed at the planar section of measured object shell and press, by the cooperation of the flexible of corrugated vacuum sucker 6 with seal chamber 7, the partial air of its inside is extruded, corrugated vacuum sucker 6 inside is made to produce negative pressure, thus be adsorbed on testee surface securely, the reacting force of back-moving spring 3 makes signal detection sensor 1 keep constant pressure with measured object surface, and then makes sensor detection signal more stable.Seal chamber 7 provides roundabout space except for returning supporting tube 2 except installing signal output terminal 8, is convenient to the compression of corrugated vacuum sucker 6, further improves its absorption property.
The capping 9 arranging sealing can provide convenient for assembling or maintenance.
