The present invention is a circular water pump which allows the suction disk to be sucked and discharged by moving the sliding disc installed on the drive shaft connected to the motor shaft to the left and right and changing only the slope. The present invention relates to a circular water pump equipped with a safety device that prevents water leakage to the rotating shaft, removes the pressure, and effectively copes with foreign matter on the drive shaft.

As shown in FIG. 3, the conventional circular water pump has a surface 33 and a surface 33 and a fan on the inner surface of the body 35 in the water pump main body 35 in which the suction hole 31 and the discharge hole 32 are formed. The end inner thread 34 is formed, and the insertion groove 36 is formed on the inner side of the main body 5, and the needle bearings 40 and 40a of the eccentric shaft 39 are fixed to the rotating shaft 38. The incision groove 43 is formed in the sliding disc 42 formed integrally with the spherical body 41, and then the sliding rod 44 having the packing grooves 44a and 44b formed on the top is cut in the incision groove 43. ) And the fan-shaped diaphragm 37 was inserted between the insertion seed grooves 45 of the sliding rod 44, but both sides of the diaphragm 37 were installed to be inserted into each of the insertion grooves 36 and 36a.

Incision grooves 43 are formed in the sliding disc 42 formed integrally with the spherical body 41 formed on the needle bearings 40 and 40a, and then packing grooves 44a and 44b are formed on the upper end. The sliding rod 44 is inserted into the incision groove 43, and the fan-shaped diaphragm 37 is inserted between the insertion seed grooves 45 of the sliding rod 44, but both sides of the diaphragm 37 are inserted into the insertion groove 36 ( 36a) to be fitted in each.

Problems of the circular pump configured as described above are as follows.

First, when water is sucked out and discharged, water leaks toward the support bearing 46 between the eccentric shafts 39 inserted into the sliding disc 42, thereby lowering the pumping efficiency.

Secondly, when foreign matter is caught between the rotary shaft 38 and the support bearing 46, the foreign matter on the rotary shaft 38 and the support bearing 46 causes the wear and rotational force of the rotary shaft 38 to drop as a result of the foreign matter. .

Third, as water leaks between the eccentric shafts 39 inserted into the spherical body 41 of the sliding disc 48, an input is generated so that a separate device capable of releasing this pressure is not provided.

Therefore, the present invention has been devised to solve the above-mentioned problems, and prevents water leakage during suction and discharge of water, and efficiently discharges the pressure generated therein, and includes a shock absorber in the drive shaft. The purpose is to maximize the pumping efficiency.

In order to achieve the object of the present invention, as the drive shaft rotates by one rotation, the rotating shaft tilted at a certain angle (about 12 °) rotates so that the inclination of the sliding disc is changed so that the left and right movements are performed so that the water is discharged at the same time as the suction. To attach a bellows to prevent leakage between the sliding disc and the front cover; Constituting a discharge hole for discharging the pressure leaked between the rotating shaft inserted into the sliding disk; It is characterized in that it is to maximize the pumping efficiency by having a safety device that can protect the rotating shaft from the foreign matter in the area where the drive shaft and the rotating shaft is fitted.

Hereinafter, with reference to the accompanying drawings the technical configuration and preferred embodiments of the present invention will be described in detail.

It will be described in detail with reference to the accompanying drawings.

The front cover (3) and the sliding disk (4) formed on the end of the drive shaft (1) connected to the shaft of the motor to have an inclination of a predetermined angle (about 12 °), and arranged on the rotating shaft (2) fastened thereto Installing and configuring a bellows 5 in between; Forming a discharge hole (3a) to one side of the front cover (3) in order to remove the pressure leaked when water leaks during the pumping between the sliding disk (4) and bellows (5); Is it erased to the drive shaft (1)? When the foreign material is caught in the rotary shaft (2) is configured to the grounding (6) and the shock absorbing spring (7) coupled to the shock absorber so as to mitigate the shock generated during the rotation.

Reference numeral 8 is a cylinder cover, 9 is a rear cover, 10 is a body, 11 is a tightening screw.

1 is an exploded perspective view showing the configuration of the present invention and Figure 2 is a cross-sectional view illustrating the operating state of the present invention. After connecting one end of the drive shaft 1 to the shaft of the motor, the motor is started.

Accordingly, as the drive shaft 1 rotates, the rotating shaft 2 rotates, but the sliding disc 4 moves in a zigzag state because the rotating shaft 2 is inclined at a predetermined angle (12 °). That is, between the inlet port 8a and the outlet port 8b in accordance with the zigzag movement of the sliding disc 4 installed inside the cylinder cover 8 located between the rear cover 9 and the front cover 3, Make a wave motion.

Accordingly, only the inclination of the sliding disk 4 is changed to suck and discharge water.

At this time, when water is sucked and discharged, water leakage occurs between the sliding disk 4 and the inner surface of the cylinder carver 8.

Although the connection part of the drive shaft 1 to which the rotation shaft 2 is fastened in the shape of leakage may be leaked, the body in which the rotation shaft 2 and the drive shaft are connected by the bellows 5 installed in the front cover 3 ( 10) Shut off water leakage to the inside.

In addition, the leaked water from the inside of the front cover (3) to the outside so that the bellows (5) is prevented from bursting by the pressure of the water leaked toward the front cover (3), the bellows (5) is installed, the discharge hole of the front cover ( It is discharged to the outlet 8b through 3a).

In addition, as the rotary shaft 2 inserted and inserted into the end of the drive shaft 1 is inclined at a predetermined angle (about 12 °) as the foreign material is trapped, water intake and discharge is not smooth, but at the end of the drive shaft 1 It is cushioned by the grounding hole 6 and the shock absorbing spring 7.

That is, the present invention is inserted into the front cover (3) by inserting the bellows (5) on the rotating shaft (2) to prevent water leakage toward the rotating shaft (2) connected to the drive shaft (1) when absorbing and discharging water It is also provided with a discharge hole (3a) through the one side of the front cover (3) to be discharged toward the discharge port (8a) in the pressure generated by the leakage of the bellows (5) side, the rotary shaft (2) and the drive shaft (1) The grounding hole 6 and the shock absorbing spring 7 are contacted with the fastened rotating shaft 2 of the drive shaft 1, which can distribute the force evenly from the foreign matter to the connection part of the drive shaft 1 and act as a noise and cushioning body. It is the summary that it was installed and configured on one side of).
