Tight stud；Piezoelectric patches；Electrode slice；Insulation tube；Felt pad；Clamp nut；Tightening nut forms, wherein the processing work of locking stud
Skill is complicated, and yield rate is low, thus slow, complicated, of high cost for storehouse for production efficiency the shortcomings that caused sensor, is not suitable for advising
Modelling is produced in batches.
The content of the invention
In view of this, the utility model is directed to the signal transducer in a kind of Fork LIquid Level Switch, to change structure
It realizes and reduces difficulty of processing, improve efficiency, reduce cost.
In order to achieve the above objectives, the technical solution of the utility model is realized in：
Signal transducer in Fork LIquid Level Switch, including clamp nut, piezoelectric patches, electrode slice, compression stud and insulation
Sheath, the inside bottom for compressing stud and being arranged on insulating sheath, the alternating structure being made of piezoelectric patches and electrode slice are set
Stud upper surface is being compressed, is being fixed above alternating structure by the clamp nut installed with the top of insulating sheath；The insulation shield
The upper inner of set is equipped with latch hook structure, and the clamp nut is equipped with the self-locking groove structure with latch hook structure cooperation, described
Latch hook structure realizes the self-locking fixing knot structure of clamp nut and insulating sheath with self-locking groove structure.
Further, the protrusion extended to axle center that the latch hook structure of the insulating sheath is set for inside, the compression
Self-locking groove structure on nut is the annular groove of lateral surface circumferential direction.
Further, the insulating sheath is integrated injection molding structure.
Compared with the prior art, the utility model has the advantage that：
To need originally the sensor device being strained and fixed by locking stud and tightening nut be changed to insulating sheath and
The fixed mode of clamp nut self-locking, and insulating sheath is moulding, overall structure processing is simple, convenient, of low cost, is applicable in
In large-scale batch production, the efficiency of production is improved, it is simple for storehouse.

Specific embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Signal transducer in Fork LIquid Level Switch, as shown in Fig. 2, including clamp nut 1, piezoelectric patches 2, electrode slice 3, pressure
Tight stud 5 and insulating sheath 4, the inside bottom for compressing stud 5 and being arranged on insulating sheath 4, by piezoelectric patches 2 and electrode slice 3
The alternating structure of composition, which is arranged on, compresses 5 upper surface of stud, by the compression with the installation of the top of insulating sheath 4 above alternating structure
Nut 1 is fixed；
The upper inner of the insulating sheath 4 is equipped with latch hook structure, and the clamp nut 1 is equipped with to be coordinated with latch hook structure
Self-locking groove structure, the latch hook structure and self-locking groove structure realize the self-locking fixing knot of clamp nut 1 and insulating sheath 4
Structure.
As shown in Figure 3,4, the protrusion extended to axle center that the latch hook structure of the insulating sheath 4 is set for inside, it is described
Self-locking groove structure on clamp nut 1 is the annular groove of lateral surface circumferential direction.
The insulating sheath 4 is integrated injection molding structure.
The sensor device being strained and fixed by locking stud 1 and tightening nut 7 will be needed to be changed to insulating sheath 4 originally
With the fixed mode of 1 self-locking of clamp nut, self-locking hook structure is devised on insulating sheath 4, there is self-locking groove on clamp nut 1
Structure, clamp nut 1 and insulating sheath 4 are fixedly connected by self-locking groove with latch nook, and insulating sheath 4 uses Shooting Technique side
Formula is process, and processing is simple, convenient, of low cost, suitable for large-scale batch production, improves the efficiency of production, standby
Storehouse is simple.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model
Protection domain within.
