Description
Technical Field
The utility model particularly relates to a connecting structure for a water pump.
Background
The existing water pump connecting structure is fixed together by two common flanges through bolts, and the inner ring edge of the flange structure has a gap, so that corrosive liquid or gas can easily permeate out, and the service life is shortened.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to overcome the defects of the prior art, a connecting structure for a water pump is provided.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a connecting structure for a water pump comprises a main connecting disc and an auxiliary connecting disc, wherein the main connecting disc and the auxiliary connecting disc are both circular, the main connecting disc and the auxiliary connecting disc are coaxially arranged, an annular groove is formed in the annular side face, opposite to the auxiliary connecting disc, of the main connecting disc, a rubber ring with a semicircular section is arranged in the annular groove, the area of the semicircular section of the rubber ring is larger than that of the rectangular section of the annular groove, a connecting cylinder is arranged on the inner ring of the main connecting disc, the outer wall of the connecting cylinder is connected with the inner wall of the main connecting disc, one end of the connecting cylinder is fixed in the main connecting disc, and the other end of the connecting cylinder extends into the inner ring of the auxiliary connecting disc;
the main connecting disc is connected with the auxiliary connecting disc through bolts.
Preferably, the length of the connecting cylinder is smaller than the total thickness of the main connecting disc and the auxiliary connecting disc.
The connecting structure for the water pump has the advantages that the rubber ring is tightly attached after being deformed by extruding the main connecting disc and the auxiliary connecting disc, so that a sealing effect is formed, the connecting cylinder can well cover the joint of the main connecting disc and the auxiliary connecting disc, and the sealing property is further improved.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of a connection structure for a water pump of the present invention;
in the figure: 1. the connecting device comprises a main connecting disc, 2 an auxiliary connecting disc, 3 a rubber ring and 4 a connecting cylinder.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, a connection structure for a water pump comprises a main connection disc 1 and an auxiliary connection disc 2, wherein the main connection disc 1 and the auxiliary connection disc 2 are both circular rings, the main connection disc 1 and the auxiliary connection disc 2 are coaxially arranged, an annular groove is formed in the annular side face, facing the auxiliary connection disc 2, of the main connection disc 1, a rubber ring 3 with a semicircular section is arranged in the annular groove, the area of the semicircular section of the rubber ring 3 is larger than that of the rectangular section of the annular groove, a connection cylinder 4 is arranged on the inner ring of the main connection disc 1, the outer wall of the connection cylinder 4 is connected with the inner wall of the main connection disc 1, one end of the connection cylinder 4 is fixed in the main connection disc 1, and the other end of the connection cylinder 4 extends into the inner ring of the auxiliary connection disc 2;
the main connecting disc 1 is connected with the auxiliary connecting disc 2 through bolts.
Preferably, the length of the connecting cylinder 4 is less than the total thickness of the main connecting disc 1 and the auxiliary connecting disc 2.
The area of the semicircular section of the rubber ring 3 is larger than that of the rectangular section of the annular groove, and the rubber ring 3 is guaranteed to have partial overflow of the annular groove and improve the sealing property under enough extrusion degree when the main connecting disc 1 and the auxiliary connecting disc 2 are attached.
Compared with the prior art, this a connection structure for water pump passes through main connection pad 1 and auxiliary connection pad 2 quotation extrusion for 3 deformations of rubber circle post-tightening, and then form sealing effect, and connecting cylinder 4 also can better cover main connection pad 1 and auxiliary connection pad 2's seam, further improves the leakproofness.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
