Description

Technical Field

[0001] The utility model relates to the technical field of water pump joints, in particular to a rotary buckle type water pump joint structure. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, so that the liquid energy output increases. The blades of the axial flow pump are generally immersed in the pool of water being sucked. Due to the high-speed rotation of the impeller, the lift generated by the blades continuously pushes the water upward, causing the water to flow out along the outlet pipe. As the impeller rotates continuously, the water is continuously pressed to a high place. In order to achieve a quick and convenient connection, the outlet of the water pump currently adopts a screw-on connection design, and a sealing ring is set at the joint after the screw-on connection is squeezed. However, this sealing method is affected by the tightening force and water pressure. When the water pressure is too high (the higher the output head, the greater the pressure at the pump outlet), it is easy to leak. Utility Model Content

[0003] The purpose of the utility model is to provide a screw-on water pump joint structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screw-on water pump joint structure, including a water outlet and a female joint, a screw-on groove is provided on the outer side of one end of the female joint, the end of the water outlet is engaged with the screw-on groove to realize axial constraint, and after the water outlet and the screw-on groove are connected, a sealing groove with a V-shaped cross-section is formed at the contact position, and a matching V-shaped sealing ring is installed in the sealing groove, and the opening of the V-shaped sealing ring faces inward and is pressed tightly against the sealing groove under the action of water pressure.

[0005] Preferably, an axial positioning pin is inserted between the screw groove and the end of the female connector, and the positioning pin is used to circumferentially fix the water outlet and the female connector.

[0006] Preferably, a radial set screw is screwed inwardly into the outer side of the screw groove, and the front end of the set screw abuts against the side surface of the positioning pin.

[0007] Compared with the prior art, the beneficial effect of the present invention is that a V-shaped sealing ring is arranged at the joint of the joint, and the water pressure of the water outlet pushes the V-shaped sealing ring to expand outward and fit tightly with the sealing groove, thereby achieving better sealing. Therefore, the present joint structure is conducive to improving the sealing and preventing leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0014] See also Figure 1-4 The utility model provides a technical solution: a spin-on water pump joint structure, including a water outlet 1 and a female joint 2. A spin-on groove 3 is provided on the outer side of one end of the female joint 2. The female joint 2 is provided with a plurality of evenly distributed protrusions along the circumference. The end of the water outlet 1 is snap-fitted with the spin-on groove 3 to realize axial constraint. After the water outlet 1 is butt-jointed with the spin-on groove 3, a sealing groove with a V-shaped cross section is formed at the contact portion. A matching V-shaped sealing ring 4 is installed in the sealing groove. The V-shaped sealing ring 4 is annular. The opening of the V-shaped sealing ring 4 faces inward and is pressed tightly against the sealing groove under pressure. The greater the water pressure, the tighter the V-shaped sealing ring 4 is pressed against the sealing groove, and the sealing effect is improved accordingly.

[0015] An axial positioning pin 5 is inserted between the screw groove 3 and the end of the female connector 2, and the positioning pin 5 is used to circumferentially fix the water outlet 1 and the female connector 2. A radial set screw 6 is screwed inwardly from the outer side of the screw groove 3, and the front end of the set screw 6 abuts against the side of the positioning pin 5. The set screw 6 is arranged vertically relative to the positioning pin 5, and the diameter of the positioning pin 5 is larger than the diameter of the set screw 6.
