Description

Water level sensor bracket diaphragm package assembly

Technical Field

The utility model belongs to the field of water level sensors, and particularly relates to a water level sensor bracket diaphragm assembling structure.

Background

At present, the connecting device of the water level sensor wood chip and the bracket mainly has three forms, the first form (shown in figure 2) is that 3 or 4 through holes are uniformly distributed in the bracket plate in 360 degrees, the corresponding diaphragm is provided with 3 or 4 bosses, the diaphragm bosses are in interference fit connection with the bracket through holes, when in production operation, the inner holes and the bosses can be assembled in an extrusion mode only by aligning, the production efficiency is low, and the assembly is not in place easily because the inner holes and the bosses cannot be completely aligned; the second (as shown in fig. 3) is that an inner hole is arranged at the center of the bracket, a boss is arranged at the center of the corresponding membrane, the boss is in clearance fit with the inner hole, the bracket is not arranged at the center of the coil, the frequency of the product is unstable, and the frequency is changed along with the vibration of the product; the third (as shown in fig. 4) is that on the basis of the second structure, the boss is in interference fit with the inner hole, the boss is extruded into the inner hole through pressure, the condition that the assembly is not in place due to improper alignment exists, the poor formed by pressure extrusion is not easy to be found, and the condition that the product quality is poor exists.

SUMMERY OF THE UTILITY MODEL

The utility model provides a water level sensor bracket diaphragm assembling structure aiming at the defects in the prior art.

In order to solve the problems, the technical scheme adopted by the utility model is as follows:

the utility model provides a level sensor bracket diaphragm package assembly, includes diaphragm and bracket, the diaphragm is the disk, and the bracket is the column body, the diaphragm center is thickening type disc, and the diaphragm center is equipped with the interior draw-in groove of type of falling T post, and the bracket tip is T type post, and the internal diameter of the interior draw-in groove of type of falling T post is less than bracket tip external diameter, diaphragm center interior draw-in groove and bracket tip interference fit.

Furthermore, the inner edge of the bottom of the inner clamping groove of the diaphragm and the outer edge of the end part of the bracket are both arc-shaped.

Furthermore, the inlet end of the inner clamping groove of the diaphragm is covered on the side of the bracket end, and the outer edge of the inlet end of the inner clamping groove is abutted against the side of the bracket end.

Detailed Description

The present invention will be described with reference to specific examples.

As shown in fig. 1, which is a schematic view of a water level sensor bracket diaphragm assembly structure of the present invention, the water level sensor bracket diaphragm assembly structure includes a diaphragm 1 and a bracket 2, the diaphragm 1 is in a disk shape, the bracket 2 is in a cylindrical shape, the center of the diaphragm 1 is a thickened disk, an inverted T-shaped column inner clamping groove 3 is arranged at the center of the diaphragm 1, the end of the bracket 2 is a T-shaped column, the inner diameter of the inverted T-shaped column inner clamping groove 3 is smaller than the outer diameter of the end of the bracket 2, the central inner clamping groove 3 of the diaphragm 1 is in interference fit with the end of the bracket 2, during the production process, the bracket 2 does not need to be punched, the production cost is reduced, the end of the bracket 2 is embedded and clamped in the inner clamping groove 3 of the diaphragm 1, the assembly mode is simple, the assembly efficiency is improved, no vibration deviation occurs, during the assembly process, the diaphragm 1 only has the condition of being assembled with the bracket 2 or not matched with the two conditions, the unqualified products can be conveniently screened out, and the quality of the assembled product is ensured.

The inner edge of the bottom of the inner clamping groove 3 of the diaphragm 1 and the outer edge of the end part of the bracket 2 are both arc-shaped 4, so that the diaphragm 1 and the bracket 2 are conveniently clamped and matched, the matching tightness is improved, and meanwhile, the outer edge of the bracket 2 is prevented from damaging the inner wall of the diaphragm 1 in the assembling process.

The inlet end of the inner clamping groove 3 of the diaphragm 1 is coated on the end part side of the bracket 2, and the outer edge of the inlet end of the inner clamping groove 3 is abutted against the end part side of the bracket 2, so that the assembling tightness of the diaphragm 1 and the bracket 2 is further improved, and the diaphragm 1 and the bracket 2 are prevented from being corroded and damaged by corrosive liquid in the using process.

Concentric annular elastic convex strips 5 are arranged at the bottom of the center of the diaphragm 1, the elastic convex strips 5 are uniformly distributed on the center face of the diaphragm 1, the anti-seismic performance of the combined structure of the diaphragm 1 and the bracket 2 is improved through the elastic convex strips 5, and the stability of a product is improved.

To sum up, a water level sensor bracket diaphragm package assembly, bracket 2 inlay card formula is installed in the interior draw-in groove 3 at diaphragm 1 center, and the assembly methods is convenient, and the cooperation is closely firm, and bracket 2 can obtain guaranteeing with diaphragm 1's cooperation precision, and in the assembling process, diaphragm 1 that bracket 2 can't pack into can be sieved out, has guaranteed the quality of product.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
