Abstract
The utility model discloses a long-acting clamping mechanism of a vibrating-string type sensor string wire, which comprises a vibrating string and end heads at both ends; a pipe body is sleeved between the end heads and the vibrating string is located in the pipe body; one end of each end head is provided with a fixing hole, the inner part of the fixing hole is embedded with a needle rod, and the vibrating string is riveted on the end head through the needle rod. According to the long-acting clamping mechanism, the design is novel, the structure is simple; and by using the axial force, the rod pier of an inner nail of an end head hole is mounded to be rough and formed to be a nail head to be connected with the vibrating string and the end heads, so that the condition of loose string wire of ordinary vibrating-string type sensor caused by the clamping of a screw is avoided, and the service life of the entire sensor is prolonged.
Description
Technical field
The utility model relates to the vibrating string type sensor technology, relates in particular to a kind of long-acting clamping device of vibrating string type sensor string wire.
Background technology
With the metallic cord of tension as the resonant transducer of sensitive element.After the length of string was confirmed, the variable quantity of its natural vibration frequency can characterize the size of the suffered pulling force of string, through corresponding metering circuit, just can obtain becoming with pulling force the electric signal of certain relation.
At present, vibrating string type sensor all is clamped in two chucks centres as induction installation with the vibratory string of tension, and vibratory string selects tungsten filament, violin string or iron wire to process.In the middle of long-term use, owing to receive the vibratory string inner tensions by the effect in the middle of two side direction, the inside contraction that vibratory string can be slowly, final vibratory string is loosening to cause sensor to be scrapped until the clamping that breaks away from chuck, and influence records the degree of accuracy of data.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of long-acting clamping device of vibrating string type sensor string wire.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of long-acting clamping device of vibrating string type sensor string wire; The termination that comprises vibratory string and two ends is arranged with body between the termination and vibratory string is positioned at body, and an end of termination has fixed orifice; Fixed orifice inside is embedded with the nail bar, and vibratory string is through following closely the bar rivet clasp on the termination.
As preferably, vibratory string is that steel wire is processed.
As preferably, follow closely bar, termination and vibratory string and be positioned on the same horizontal line.
Compared with prior art; The advantage of the utility model is: modern design, and simple in structure, through utilizing axial force; Nail bar pier in the end holes is thick and form ailhead; It is connected with vibratory string, termination, the string wire relaxation cases of having avoided common vibrating string type sensor to utilize the screw clamping to produce, thus prolonged the serviceable life of whole sensor.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, termination; 2, nail bar; 3, body; 4, vibratory string; 5, fixed orifice.
Embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of embodiment as the utility model; Consult Fig. 1; The utility model comprises the termination 1 at vibratory string 4 and two ends, is arranged with body 3 between the termination 1 and vibratory string 4 is positioned at body 3, and an end of termination 1 has fixed orifice 5; Fixed orifice 5 inside are embedded with nail bar 2, and vibratory string 4 is through following closely bar 2 rivet clasps on termination 1.Vibratory string 4 is processed for steel wire.Nail bar 2, termination 1 and vibratory string 4 are positioned on the same horizontal line.
Through utilizing axial force; Nail bar 2 piers in the fixed orifice of termination 1 one ends 5 are thick and form ailhead; It is connected with termination 1 with vibratory string 4, the string wire relaxation cases of having avoided common vibratory string 4 formula sensors to utilize the screw clamping to produce, thus prolonged the serviceable life of whole sensor.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiment shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
