Description

Technical Field

[0001] The utility model relates to the field of water pipe connection structures, more specifically to a novel water pipe connection piece. Background Art

[0002] The external water pipe quick connector is mainly used to connect two external water pipes, or to connect an external water pipe to a water pump, or to connect an external water pipe to other equipment. The existing snap-on quick connector has certain limitations. After the elastic part is fatigued, the snap-on quick connector will be damaged. Therefore, a new type of water pipe connector is designed. Summary of the invention

[0004] In order to solve the above technical problems, the utility model relates to the field of water pipe connection structures, more specifically, a new type of water pipe connector, including a first connection part, the first connection part is provided with a flange, an external threaded part and a step part;

[0005] The second connecting part is provided with an internal threaded part, an extension part, a polygonal part and a protruding part; the extension part is located on the side of the polygonal part; and provides a fulcrum when rotating the second connecting part.

[0006] The external threaded portion cooperates with the internal threaded portion, and the axis lines of the first connection portion and the second connection portion coincide or are parallel, providing a water pipe quick connector that reinforces the connection position and avoids disconnection of the connection position.

[0007] As a further optimization of the technical solution, the step portion described in a new type of water pipe connector of the utility model is a rotating body structure formed around the axis line of the first connecting part, the protruding portion is a rotating body structure formed around the axis line of the second connecting part, and the outer circle diameter of the step portion is smaller than the inner circle diameter of the protruding portion.

[0008] As a further optimization of the technical solution, the step portion of a new type of water pipe connector of the utility model is provided with at least one step along the axis line to clamp the water pipe.

[0009] As a further optimization of the technical solution, in the utility model, the end of the first connecting part away from the step part described in the new water pipe connecting piece is a connecting female head or a connecting male head.

[0010] As a further optimization of the technical solution, the first connecting part and the second connecting part of the novel water pipe connecting piece of the utility model are integrally formed.

[0011] The beneficial effects of the novel water pipe connector of the utility model are:

[0012] The utility model discloses a novel water pipe connector, which provides a water pipe quick connector which can reinforce the connection position and avoid disconnection of the connection position. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example:

[0021] Combine the following Figure 1-4 To explain this embodiment, the utility model relates to the field of water pipe connection structures, and more specifically, to a new type of water pipe connector, including a first connection portion 1, on which a flange 11, an external threaded portion 12 and a step portion 13 are provided;

[0022] The second connecting portion 2 is provided with an internal thread portion 21, an extension portion 22, a polygonal portion 23 and a protruding portion 24; the extension portion 22 is located on the side of the polygonal portion 23; Figure 1 and Figure 2 As shown, the flange 11 can prevent the first connection part 1 from completely entering the second connection part 2 , and the extension part 22 increases the force point and torque for rotating the second connection part 2 , making it easier to rotate the second connection part 2 .

[0023] The external threaded portion 12 cooperates with the internal threaded portion 21, and the axis lines of the first connection portion 1 and the second connection portion 2 coincide or are parallel, providing a water pipe quick connector that reinforces the connection position and avoids disconnection of the connection position.

[0024] The step portion 13 is a body of revolution structure formed around the axis of the first connection portion 1, and the protrusion 24 is a body of revolution structure formed around the axis of the second connection portion 2, and the outer diameter of the step portion 13 is smaller than the inner diameter of the protrusion 24. The protrusion 24 cooperates with the step portion 13 to fix the water pipe S between the first connection portion 1 and the second connection portion 2.

[0025] The step portion 13 is provided with at least one step along the axis, which is convenient for clamping the water pipe, especially the PU rubber water pipe.

[0026] The first connection part 1 and the second connection part 2 are integrally formed. The end of the first connection part 1 away from the step part 13 is a female connection head or a male connection head. The connection body of the first connection part 1 and the second connection part 2 forms a "male head" or a "female head", which is convenient for the male and female heads to match, and then connect the two sections of water pipes. This technical solution has reliable and tight connection and is not easy to damage.

[0027] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
