Description

Technical Field

[0001] The utility model relates to the technical field of three-way joint structures, in particular to a three-way joint which is convenient to install. Background Art

[0002] The three-way pipe joint is a common connector for pipe connection. It has three interfaces for dividing an extra branch in the pipe. In existing pipes for tap water or household water, the three-way joint is commonly used to connect water pipes by hot melting and gluing. These two connection methods are prone to leakage at the connection position, especially in the gluing method. The solidification process of the glue takes a while. If the installation operation continues during the solidification process, it is easy to cause unstable gluing. In view of the above problems, the present invention provides a solution. Utility Model Content

[0003] The utility model aims to provide a three-way joint which is convenient to install.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A three-way joint that is easy to install, includes a joint body and three interfaces, the outer wall of each interface is set to be conical, with a thick outer end and a thin inner end, an outer wall is provided with an external thread, and a locking screw cap cooperates with the external thread on the outer wall through an internal thread structure, and an adhesive section and a sealing deformation groove are provided in the installation cavity on the inner side of the interface, the adhesive section is a smooth cylindrical cavity, and the adhesive section is provided at the outer end of the installation cavity, the sealing deformation groove is provided inside the installation cavity, and a sealing ring is installed inside the sealing deformation groove, and the diameter of the installation cavity is larger than the diameter of the inner cavity of the joint body, so that the connection position of the two forms an installation positioning shoulder.

[0006] Furthermore, there are multiple sealing deformation grooves in the interface, and the multiple sealing deformation grooves are evenly distributed, and each sealing deformation groove is equipped with a sealing ring. By setting up multiple sealing deformation grooves, the locking screw cap can gradually squeeze the outer wall to deform when cooperating with the external thread, thereby improving the connection strength.

[0007] Furthermore, a glue groove is provided between the glue section and the sealing deformation groove. The setting of the glue groove can store excess glue applied on the glue section when installing the water pipe and form a reinforced closed loop at this position.

[0008] Furthermore, the bottoms of the glue groove and the sealing deformation groove are arc grooves. Setting the bottoms of the two grooves into an arc shape can reduce the local stress at the bottom of the groove and increase the life of the joint.

[0009] Furthermore, a joint flange is provided at the end of each interface, and the joint flange can thicken the opening thickness of the interface and increase its strength.

[0010] In summary, the utility model has the following beneficial effects: the three-way joint structure designed in the utility model can be quickly connected to the water pipe, and has the advantages of reliable connection and strong sealing, etc., improving the shortcomings of the traditional water pipe and three-way connection, such as long solidification time and easy leakage.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-3 As shown, a three-way joint that is easy to install includes a joint body 1 and three interfaces 6. The outer wall 5 of each interface 6 is set to be conical, with a thick outer end and a thin inner end. The outer wall 5 is provided with an external thread 4. The locking screw cap 3 cooperates with the external thread 4 on the outer wall 5 through an internal thread structure. An adhesive section 7 and a sealing deformation groove 9 are provided in the installation cavity on the inner side of the interface 6. The adhesive section 7 is a smooth cylindrical cavity, and the adhesive section 7 is provided at the outer end of the installation cavity. The sealing deformation groove 9 is provided inside the installation cavity. A sealing ring 10 is installed inside the sealing deformation groove 9. The diameter of the installation cavity is larger than the diameter of the inner cavity of the joint body 1, so that the connection position of the two forms an installation positioning shoulder.

[0017] Further, such as Figure 3 As shown, there are multiple sealing deformation grooves 9 in the interface 6, and the multiple sealing deformation grooves 9 are evenly distributed, and each sealing deformation groove 9 is installed with a sealing ring 10. The multiple sealing deformation grooves 9 can make the locking screw cap 3 gradually squeeze the outer wall 5 to deform when cooperating with the external thread 4, thereby improving the connection strength.

[0018] Further, such as Figure 3 As shown, a glue groove 8 is further provided between the adhesive section 7 and the sealing deformation groove 9. The setting of the glue groove 8 can store excess glue applied on the adhesive section 7 when installing the water pipe and form a reinforced closed loop at this position.

[0019] Furthermore, the bottoms of the glue groove 8 and the sealing deformation groove 9 are arc grooves. Setting the bottoms of the two grooves in an arc shape can reduce the local stress at the bottom of the groove and increase the service life of the joint.

[0020] Furthermore, a joint flange 2 is provided at the end of each interface 6, and the joint flange 2 can thicken the opening thickness of the interface 6 to increase its strength.

[0021] Working principle: During installation, apply glue evenly on the adhesive section 7 of the interface 6, and then insert the water pipe head into the installation cavity of the interface 6. During the insertion process, the outer wall of the water pipe contacts the outer wall of the adhesive section 7. At the same time, the outer wall of the water pipe squeezes excess glue into the glue groove 8. The sealing ring 10 inside the sealing phase-changing groove 9 contacts the outer wall of the water pipe and produces a certain deformation. Then rotate the locking screw cap 3, and the locking screw cap 3 rotates and squeezes the conical outer wall 5, causing it to shrink inward and fit tightly against the water pipe to generate a fixing force. There is no need to wait for the glue to solidify before proceeding to the next construction operation, thereby improving the installation efficiency.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
