Abstract

A water pressure reduction connecting device comprises a connecting body 10 having an abutment section 121 to mount to a fixing groove 123 of an end sheath 124, and a smaller-diameter inlet chamber (14, Fig. 3) integrally extending therein for the accommodation of a movement element 20 having a water-influx passage therein 21. The inlet chamber 14 has inlet orifices (141, Fig. 3) corresponding to an inlet end 11 of the connecting body 10. The movement element 20 has restrictive protrusions 23 to be inserted into the inlet orifices 141, and an annular groove 25 with a watertight ring 24 to seal tight against the inlet chamber 14, forming a restrictive space therebetween. The movement element 20 also has a larger diameter water sealing section 27 to abut tight against the abutment section 121. Therefore, the movement element 20 can slide back and forth according to the change of water pressure from the inlet and outlet ends to alter the space revealed by the inlet orifices 141 and regulate the water flow, thus achieving water-pressure reduction and stabilization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to Fig. I showing an exploded perspective view of the present invention (accompanied by Figs. 2 to 6 inclusive). The present invention relates to * ** an easy-type water-pressure reduction connecting device, comprising a connecting body 10 having an elastic fitting (without shown in the illustration) mounted to one side to match to an upper-and-lower movable coupling tube 101 and form an inlet end 11 therewith. The connecting body 10 also has the other end defined by a guide * section 129, a stop flange 122 protruding outwards, and a smaller-diameter and conic tapered abutment section 121 extending thereon to moint to a fixing groove 123 of an end sheath 124. The end sheath 124 has an outlet port 125 extending through the center thereon, and a lower section defined by an external-threaded section 126 and multiple engaging teeth 127 extending outwards thereon to be fixed to a locking sleeve 128 defined by a conic tapered inner diameter, and form an outlet end 12 therewith. The connecting body 10 has the internal middle section equipped with a ringed seat 13, and a smaller-diameter inlet chamber 14 integrally extending and protruding to both sides thereon to match to a movement element 20 thereby. The inlet chamber 14 has the opening end situated to the same side of the guide section 129 thereof, and multiple inlet orifices 141 annularly cut at the outer circumference of the other side corresponding to the inlet end Ii thereof. The inlet chamber 14 also has multiple oblique guide slopes 142 annularly spaced out at the internal middle section thereon. The movement element 20 has a central water- influx passage 21 extending there-through, and a middle section equipped with a cross-shaped stop block 211 defined by multiple apertures 212 thereon to fluidly connect to the water-influx passage 21 thereby. A spring element 22 is mounted to one side of the water-influx passage 21 to be precisely restricted in position by the stop block 211 thereof. The movement element 20 also includes oblique guide surfaces 23 each equipped with a positioning protrusion 231 extending at the external circumference of one end edge thereon to be respectively guided to the oblique guide slopes 142 of the inlet chamber 14 and forced therein, permitting the positioning protrusions 231 to * .* precisely insert to the inlet orifices 141. Then, the spring element 22 will abut against the end surface of the inlet chamber 14 and push the movement element 20 to ***s e. * *

move towards the guide section 129, permitting the inlet orifices 141 to fluidly connect to the water-influx passage 21 thereby. The movement element 20 also has * the middle section defined by an annular groove 25 to which a watertight ring 24 is mounted so as to seal against the internal surface of the inlet chamber 14 and form a back-and-forth movable restrictive space 26 with the positioning protrusions 231 thereof. The movement element 20 also has the other end equipped with a larger-diameter water-sealing section 27 with a waterproof ring 271 mounted thereto to abut tight against the guide section 129 thereby. The water-sealing section 27 thereof has a ringed groove 272 depressed thereon for the accommodation of the waterproof ring 271 therein, and an arcuate grooved area 273 defining the end surface thereon.

Please refer to Fig. 7. When water flow flushes into the inlet end 11 of the connecting body 10, the water flow will be blocked by the ringed seat 13 and the inlet chamber 14 to enter each inlet orifice 141 of the inlet chamber 14, and pass through the water-influx passage 21 and the apertures 212 of the stop block 211 of the movement element 20. Then, the water flow will flush through the outlet port 125 of the end sheath 124 to be transported outwards via the outlet end 12 thereby.

Meanwhile, the back-and-forth movable restrictive space 26 formed between the watertight ring 24 and the positioning protrusions 231 of the movement element 20 is utilized to match to the inlet orifices 141 of the connecting body 10 and be supported by the elasticity of the spring element 22. In case the water pressure coming from the outlet end 12 is larger than that from the inlet end II, the water flow blocked by the water-sealing section 27 will flush backwards along the arcuate grooved area 273 to generate a pushing force which will then press the movement * ** element 20 to slide towards the inlet end 11 and compress the spring element 22 * SdS * therewith. Then, the inlet orifices 141 blocked by the movement element 20 will * S sequentially narrow down to reduce the amount of the water influx, achieving the reduction and stabilization of the water pressure thereby. And when the water-sealing section 27 of the movement element 20 is flushed backwards by strong water pressure (referring to Fig. 8), the movement element 20 will quickly slide along the guide section 129 till abutting against the end surface of the inlet chamber 14, permitting the restrictive space 26 to accurately block the inlet orifices 141 so as to reduce the water outflow and achieve quick reduction of the water pressure thereby.

When the water pressure from the outlet end 12 is lower than the elasticity of the spring element 22, the spring element 22 will rebound via its elasticity, pushing the positioning protrusions 231 of the movement element 20 to slide along the inlet orifices 141, and the restrictive space 26 to move towards the outlet port 125 so as to recover the former position thereof. Therefore, the movement element 20 thereof can automatically slide back and forth according to the amount of water pressure so as to reduce and stabilize the water pressure, ensuring the water to be transported outwards in a stable flow and achieving the best application state thereby. * ** ** . * S* S... * S
