Abstract
The utility model relates to a sensor diaphragm. A middle canvas layer is wrapped with rubber layers positioned at both sides; a convex point is arranged at the bottom of the sensor diaphragm; the convex point is in a three-layer structure, the innermost layer combined with the bottom of the diaphragm is a convex point rubber layer, the middle layer is a convex point canvas layer, and the outermost side layer is a plastic layer. According to the utility model, the convex point is arranged on the sensor diaphragm, and the canvas layer and the rubber layers are increased, so that the service life of the diaphragm is greatly prolonged.
Description
Technical field: the utility model relates to a kind of diaphragm of liquid sensor, the diaphragm on especially a kind of automobile engine oil sensor.
Background technology: sensor diaphragm, owing to often will promoting fluid, is therefore easy to wearing and tearing, and the life-span is very short.
Summary of the invention: for above-mentioned the deficiencies in the prior art, the utility model provides longer sensor diaphragm of a kind of life-span.
For achieving the above object, the technical solution adopted in the utility model is: sensor diaphragm, the canvas layer in the middle of the rubber layer of both sides is wrapped in, is provided with salient point in sensor diaphragm bottom.Salient point is three-decker, with the innermost layer of diaphragm bottom combination be salient point rubber layer, centre is salient point canvas layer, outermost is plastic layer.
The utility model is provided with salient point in sensor diaphragm, and has increased canvas layer and rubber layer, and greatly improve the service life of diaphragm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the cutaway view of embodiment 1.
Fig. 3 is the cutaway view of salient point.
Fig. 4 is the structural representation of embodiment 2.
Fig. 5 is the structural representation of embodiment 3.
The specific embodiment:
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, intactly description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Give the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3: sensor diaphragm, the canvas layer 3 in the middle of the rubber layer 1,4 of both sides is wrapped in, is provided with four salient points 1 in sensor diaphragm bottom.Salient point 1 is three-decker, with the innermost layer of diaphragm bottom combination be salient point rubber layer 6, centre is salient point canvas layer 7, outermost is plastic layer 5.
As shown in Figure 4: its structure is similar to embodiment 1, just salient point is 6.
As shown in Figure 5: its structure is similar to embodiment 1, just salient point is 7.
