Referring now to Figure 9. A conventional water flow coupling device 30 comprises a body 31 having the upstream section defined by multiple orifices 311 on each of which an insert block 32 is received. Also, a spring 321 is mounted to abut elastically against the insert blocks 32 and fit a coupling tube 33 movable in the upstream-downstream direction, forming an inlet end in this way. The body 31 also has the downstream section defined by an externally threaded section 311 and multiple engaging teeth 312 extending outwardly therefrom to fit on a locking sleeve 34 defined by a tapered inner diameter forming an outlet end for the outward transport of the water supply in this way. However, the coupling device 30 does not have a water pressure reduction arrangement. In the event of unstable water pressure coming from the water supply, the fluid can be ejected incoherently outwards by the connecting device 30, alternating a sudden or sudden strong flow, which can cause a great deal of inconvenience and inconvenience in its application. It is therefore a principal object of the present invention to provide an easy-to-type water pressure reducing coupling device, in which a coupling body has an end equipped with an abutment section for mounting on an end sheath. and forming a separate type assembly, whereby a movable member can be readily received in an inlet chamber disposed within the connector body to control the amount of water flow in this manner, providing a simple and easy assembly structure to reduce the cost of materials and adapt to the economic benefits for a greater competitive breakthrough in the market.

Referring to Figure 1 (with Figures 2 to 6 inclusive), it can be seen that an exploded perspective view of the present invention has been shown. The present invention relates to an easy-to-use water pressure reducing coupling device comprising a coupling body 10 having an elastic connection (not shown in the drawing), mounted on one side to accommodate a coupling tube 101, movable in the upstream-downstream direction, and form an inlet end 11 with it.

The connecting body 10 also has the other end defined by a guide section 129, an outwardly projecting flange 122, and a smaller diameter and tapered tapered abutment section 121 extending over it for mounting on an attachment groove 123 of an end sheath 124. The end sheath 124 has an outlet port 125 extending through the center thereof, and a defined lower section by an externally threaded section 126 and multiple engaging teeth 127 extending outwardly thereon to be attached to a locking sleeve 128 defined by a tapered internal diameter and forming an outlet end 12 with him. The connecting body 10 has the internal middle section equipped with an annular seat 13, and an inlet chamber 14 of smaller diameter extending in one piece and projecting on both sides thereof for s adapt to a movable member 20 in this way. The inlet chamber 14 has the opening end located on the same side as the guide section 129 of the connecting body 10, and multiple inlet openings 141 annularly cut at the outer periphery of the other side. corresponding to the inlet end 11 of the connector body 10. The inlet chamber 14 also has multiple oblique guide slopes 142 spaced annularly at the internal middle section thereof. The movable member 20 has a central water inlet passage 21 extending therethrough and a middle section equipped with a cross-shaped stop block 211 defined by multiple openings 212 thereon for a fluidic connection to the water inlet passage 21 in this way. A spring member 22 is mounted on one side of the water inlet passage 21 to be precisely restricted in position by the stop block 211 thereof. The movable member 20 also includes oblique guide surfaces 23, each provided with a locating projection 231 extending at the outer periphery of an end edge thereon to be respectively guided toward the guide slopes. obliquely 142 of the inlet chamber 14 and forced into it, allowing the positioning projections 231 to be introduced accurately into the inlet ports 141. Then, the spring element 22 will abut against the end surface of the inlet chamber 14 and push the movable member 20 to move it towards the guide section 129, allowing the inlet ports 141 to connect fluidically to the inlet passage 21 of this way. The movable member 20 also has the average section defined by an annular groove 25 on which a watertight ring 24 is mounted to seal against the inner surface of the inlet chamber 14 and to form a gap space. restriction 26 movable back and forth with the positioning projections 231 thereof. The movable member 20 also has the other end equipped with a larger diameter watertight section 27 with a watertight ring 271 mounted thereon to closely abut the section. 129 in this way. The watertight section 27 has a ring groove 272 pressed thereon for receiving the water-tight ring 271, and an arc-shaped groove area 273 defining the surface of the watertight ring 271. end of coupling body 10.

Referring to FIG. 7, it can be seen that as the flow of water flows into the inlet end 11 of the connector body 10, the flow of water will be blocked by the annular seat 13 and the inlet chamber 14 to enter each inlet port 141 of the inlet chamber 14 and pass through the water inlet passage 21 and the openings 212 of the stop block 211 of the movable member 20. Next, the flow of water will be discharged through the outlet port 125 of the end sheath 124 to be transported out through the outlet end 12 of the this way. In the meantime, the reciprocable restriction space 26 formed between the watertight ring 24 and the locating projections 231 of the movable member 20 is used to fit the orifices of inlet 141 of the connecting body 10 and being supported by the elasticity of the spring element 22. In the case where the water pressure coming through the outlet end 12 is greater than that coming from the end of the At the inlet 11, the flow of water blocked by the watertight section 27 will discharge back along the arc-shaped groove area 273 to generate a pushing force which will press then the movable member 20 to slide towards the inlet end 11 and compresses the spring member 22 with it. Then, the inlet ports 141 blocked by the movable member 20 will taper sequentially to reduce the amount of water supply, thereby achieving the reduction and stabilization of the water pressure in this manner. Also, when the watertight section 27 of the movable member 20 is forced backward by a high water pressure (see Figure 8), the movable member 20 will slide rapidly along the guide section 129 until it abuts against the end surface of the inlet chamber 14, allowing the restriction space 26 to accurately block the inlet ports 141 so as to reduce water flow and achieve a rapid reduction in water pressure in this way. When the water pressure from the outlet end 12 is less than the elasticity of the spring member 22, the spring member 22 will bounce through its elasticity, pushing the locating projections 231 into position. the movable member 20 to slide along the inlet ports 141 and the restriction space 26 to move to the outlet port 125 so as to recover the old position thereof. Therefore, the movable member 20 thereof can automatically slide back and forth in accordance with the amount of water pressure so as to reduce and stabilize the water pressure, ensuring that the water will be transported outward with a stable flow and achieving the best state of application in this way.
