Abstract

The utility model relates to a water pipe connector. The utility model provides a pipe connecting terminal which is able to be conveniently and quickly disassembled and assembled. The utility model comprises at least a connecting pipe body and a lock ring which is combined on the convex pipe. An end of the connecting pipe body is convex pipe. The connecting pipe body is a pipe body provides a through hole. An inverted spine-shaped convex tooth ring is arranged at the outer circum ring of the extremity of the convex pipe. A reverse outer screw thread is arranged at the intermediate section of the convex pipe. A ring groove is formed between the reverse outer screw thread and the convex tooth ring. The lock ring provides a reserve inner screw thread corresponding to and combined with the reverse outer screw thread of intermediate section of the convex pipe of the connecting body.

Description

Waterpipe couplings

Technical field

The utility model belongs to pipe joint, particularly a kind of waterpipe couplings.

Background technique

Waterpipe couplings system prolongs in order to connect between the water pipe, or water pipe is connected in a kind of generation of water jetting apparatus.Traditional waterpipe couplings is known by popular, and its water pipe is to schedule on the pipe joint for sealed group to spiral way with conrotatory by lock ring.It is, all must earlier lock ring be separated the pipe joint cover and organize on water pipe when desiring the interlocking water pipe when each that right so institute brings inconvenience, treat the water pipe sleeve group behind pipe joint again with lock ring locking, it is inconvenient to cause assembling.

Summary of the invention

The purpose of this utility model provide a kind of tear open prescription just, waterpipe couplings rapidly.

The utility model comprises that at least one end is the connection body of protruding pipe and is screwed together in lock ring on the protruding pipe; Connecting body is the body that is provided with through hole, and the terminal peripheral ring of protruding pipe is established barb shape double wedge edge; Protruding pipe stage casing is provided with the reverse outside thread with the intermarginal formation ring groove of double wedge; Lock ring is provided with and connects the reverse internal thread that the reverse external thread section in the protruding pipe of body stage casing is corresponding and screw togather.

Wherein:

The two ends that connect body are all protruding pipe.

The other end that connects body is and the group connecting part of water jetting apparatus winding outer circumference diameter greater than protruding pipe diameter; Group connecting part is cylindrical, and week is provided with the water stop ring pad for being provided with the screw with the internal thread of water jetting apparatus lock group in the inner bolt hole bottom group in it.

The lock ring outboard end forms the interior ring inclined-plane that extends out.

The group connecting part peripheral ring is provided with on-slip roller line.

The group connecting part periphery forms the polygon fin.

The group connecting part peripheral ring is established outer spiral shell.

Because the utility model comprises at least one end and is the connection body of protruding pipe and is screwed together in lock ring on the protruding pipe; Connecting body is the body that is provided with through hole, and the terminal peripheral ring of protruding pipe is established barb shape double wedge edge; Protruding pipe stage casing is provided with the reverse outside thread with the intermarginal formation ring groove of double wedge; Lock ring is provided with and connects the reverse internal thread that the reverse external thread section in the protruding pipe of body stage casing is corresponding and screw togather.When the utility model and water pipe are carried out interlocking, be earlier lock ring to be put to deciding stop bit with the counter clockwise direction turn and toward intrinsic displacement, at this moment, can make the double wedge edge of protruding pipe end and ring groove position expose fully; Then with the water pipe sleeve group in double wedge edge periphery, and making water pipe be inserted in end, to overlap to the ring groove position be preferable; Then,, be packed in the terminal periphery of water pipe, promptly finish the interlocking action up to lock ring with lock ring turn and toward outer displacement in a clockwise direction; Lock ring needn't be separated the connection body in the interlocking mode of contrary rotation direction action, and directly turn can be with the water pipe packing; Otherwise when desiring to disassemble water pipe, water pipe can be separated, not only tear prescription open just, and tear group open rapidly, thereby reach the purpose of this utility model toward interior turn.

Embodiment

As shown in Figure 1 and Figure 2, the utility model comprises connection body 10 and lock ring 20.

Connect body 10 for being provided with the body of through hole, the one end is a group connecting part 11, and its other end is the protruding pipe 14 of diameter less than group connecting part 11 diameters.Also can be as shown in Figure 8, the two ends that connect body 10a are all protruding pipe 14.

As shown in Figure 1, group connecting part 11 is cylindrical, and its peripheral ring is provided with on-slip roller line 15; Also can be as Fig. 5, shown in Figure 6, group connecting part 11 is cylindrical, and its periphery forms polygon fin 16; Also can be as shown in Figure 7, group connecting part 11 is cylindrical, and its peripheral ring is established outside thread 17; Week is provided with water stop ring pad 13 for being provided with the screw with the internal thread 12 of water jetting apparatus lock group in the inner bolt hole bottom group in the group connecting part 11.

Protruding pipe 14 terminal peripheral rings are established barb shape double wedge edge 141, and protruding pipe 14 stage casing peripheries are provided with and 141 reverse external thread sections 142 that constitute ring groove 143 of double wedge edge.

Lock ring 20 is provided with and connects the reverse internal thread 21 that the protruding pipe of body 10 14 stage casing external thread sections 142 are corresponding and screw togather, and forms the interior ring inclined-plane 22 that extends out in lock ring 20 outboard ends.

When the utility model and water pipe 30 are carried out interlocking, as Fig. 2, Fig. 3, shown in Figure 4, system is moved to lock ring 20 earlier and decides stop bit and put with the counter clockwise direction turn and toward group connecting part 11, at this moment, can make the double wedge edge 141 of protruding pipe 14 ends and ring groove 143 positions expose fully; Then water pipe 30 covers are organized in double wedge edge 141 peripheries, and making water pipe 30 be inserted in end, to overlap to ring groove 143 positions be preferable; Then,, be packed in water pipe 30 terminal peripheries, promptly finish the interlocking action up to the interior ring inclined-plane 22 of lock ring 20 with lock ring 20 turn and toward outer displacement in a clockwise direction.

The utlity model has following effect and advantage:

The utility model provides a kind of interlocking mode of contrary rotation direction action, and lock ring 20 needn't be separated and be connected body 10, and directly turn can be with water pipe 30 packings; Otherwise when desiring to disassemble water pipe 30, water pipe 30 can be separated, tear, organize all convenient, the practical progress rapidly of water pipe open so reach toward interior turn.
