[0029] First embodiment

[0030] See Figure 1 and 2 This embodiment provides a lever-type quick connector with a deflection angle, which includes a quick-change male connector 110 and a quick-connect female connector 120 connected by a lever, wherein the tail section of the quick-change male connector 110 is provided with an expansion pipe section inclined downward, so that the quick-connect female connector 120 connected thereto has a deflection angle inclined downward, which is convenient for connecting the water pipe.

[0031] Specifically, the connection section between the quick-change male connector 110 and the water inlet is a horizontal section 111. The portion entering the water inlet has a first notch 112 angled downward from top to bottom. This first notch 112, which enters the water pump, is less prone to leaks than conventional vertically oriented connectors. First notch 112 is tilted 5-15 degrees downward from the connecting lug, a slightly inclined surface that facilitates assembly and prevents leaks while also minimizing material waste.

[0032] The outer wall of the horizontal section 111 is also fixed with a connecting ear 113, which is distributed in a circular array based on the axis of the horizontal section 111. The connecting ear 113 and the connection point of the outer shell are connected by bolts. At the same time, a sealing ring is also provided between the horizontal section 111 and the water inlet of the water pump to further prevent water leakage.

[0033] The tail of the horizontal section 111 is provided with a second cutout 114 inclined from top to bottom to ensure smooth water flow. The inclination angle of the second cutout 114 is 15-30°. In this embodiment, the deflection angle of the expansion section is 18°. The second cutout 114 exists inside the quick-change male connector 110 and is used to distinguish the expansion section 115 from the horizontal section 111. The expansion section 115 and the horizontal section 111 are made by one-piece molding or welding technology. Therefore, the second cutout 114 cannot be seen from the outside of the quick-change male connector 110.

[0034] The tail section of the quick-change male connector 110 is an expansion section 115, whose inner diameter is larger than that of the horizontal section 111. In this embodiment, the ratio of the inner diameters of the horizontal section 111 to the expansion section 115 is 1:1.2-1.4. A downward deflection angle exists between the expansion section 115 and the horizontal section 111, ensuring that the water flow from the quick-connect female connector 120 can quickly and stably enter the quick-change male connector 110. The outer wall of the expansion section 115 is provided with an annular groove 116 for mounting a lever, which allows the quick-connect female connector 120 and the quick-change male connector 110 to be quickly connected.

[0035] Specifically, the quick-connect female connector 120 includes an assembly section 121 and a drainage section 122. The assembly section 121 is covered on the outside of the expansion section 115. The assembly section 121 is equipped with a lever 123. The rotating handle of the lever 123 can be inserted into the annular groove 116 to lock the quick-connect female connector 120 and the quick-change male connector. A sealing gasket 130 is provided between the quick-change male connector and the quick-connect female connector; the inner diameter of the drainage section 122 is the same as the inner diameter of the expansion section 115, and part of the pipe section of the drainage section 122 is inserted into the expansion section 115 to prevent water leakage while enhancing the positioning effect during connection, thereby achieving quick assembly.

[0036] The assembly section 121 and the drainage section 122 are an integral pipe section, wherein the assembly section 121 is cylindrical in shape. The outer wall of the assembly section 121 is provided with a plurality of assembly seats distributed in a circumferential array for assembling the lever 123. The center of the assembly seat is provided with a hollow, so that the rotating portion of the lever 123 handle can be snapped into the hollow. The thickness of the pipe section at the assembly seat position is thinner than the thickness of the pipe sections at the front and rear ends, and reinforcing ribs are also provided at equal intervals at this pipe section position. A core shaft is mounted on the assembly seat, and the lever 123 is provided on the core shaft. When the lever 123 is lowered, the rotating portion of the lever 123 presses against the annular groove 116, thereby quickly pressing the quick-change male and quick-connect female connectors 120. The cross-section of the annular groove 116 is a tapered arc groove, which provides locking space and release space during the rotation of the lever 123. The rotating portion of the lever 123 is an eccentric cam operating arm, and the specific principle is the same as other lever 123-type quick connectors on the market. The handle of the lever 123 is further provided with a connecting ring.

[0037] In the improvement of the quick-connect female connector 120, the pipe section of the drainage section 122 is lengthened, and the outer wall of the drainage section 122 is provided with equally spaced assembly shallow grooves 124. The spacing of the assembly shallow grooves 124 is widened to prevent the water pipe from falling.

[0038] See Figure 3 The lever-type quick connector with a deflection angle in this embodiment can be applied to water pumps or mud water pumps, seawater pumps and other pump bodies. It is only necessary to connect the lever-type 123 quick connector with a deflection angle to the water inlet end of the pump body.

[0039] In summary, the advantages of the improved 123-type quick connector with a deflection angle in this embodiment are:

[0040] 1. To address the inconvenience of existing quick connectors, the present invention has redesigned a new quick connector. The male end of the quick connector is configured with a downward deflection angle. At the same time, the long drainage section 122 of the female quick connector is used to connect the water pipe. This allows the water pipe to be assembled by simply lifting it upwards during docking. Compared to the original horizontal connector, this eliminates the need for excessive time spent adjusting the connection between the water pipe and the connector.

[0041] 2. The quick-change male connector 110 is simultaneously configured with a horizontal section 111 and an expansion section 115 so that when a large amount of water enters from the quick-change female connector, it can be pressurized and accelerated in the horizontal section 111, thereby increasing the flow rate and preventing sediment-prone media such as mud from causing sedimentation and blockage in the water pump.
