Description

Technical Field

[0001] This utility model relates to a quick-connect tee for water pipes, specifically a bamboo-joint type quick-connect tee with clamping mechanism. Background Technology

[0002] Quick-connect tees, also known as tee quick couplings, are a common type of pipe fitting in industrial piping systems. They are mainly used for the rapid assembly of three pipes. Their core function is to split or merge fluid media, and they are suitable for scenarios involving the transmission of liquids, gases, and other media. Some quick-connect tees have the tee pipe located at and connected to a ball-type quick-connect assembly, such as the Chinese patent document CN215950723U, authorized announcement date 2022.03.04, utility model title "A quick-connect structure for a tee pipe"; and the Chinese patent document CN222925133U, authorized announcement date 2025.05.30, utility model title "Modible quick-connect fitting". However, the aforementioned ball-type quick-connect assembly or movable quick-connect fitting has a structure design with a ball head at one end and a quick connector at the other. It is difficult to use the ball-type quick-connect assembly or movable quick-connect fitting of the branch pipe on one side of the tee as a ball-type universal joint to connect with an atomizing nozzle with a ball head, resulting in inconvenience in extending the number of sections, inconvenience in angle adjustment, and inconvenience in installation. At the same time, the bottom or side of the tee corresponding to the ball head connection at the top of the tee lacks clamping facilities, making installation and fixing inconvenient. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a bamboo-joint quick-connect tee with clamping mechanism, thereby solving the technical problems of existing similar products where the middle branch pipe is rarely connected to the top quick-connect tee via a ball-type universal joint, resulting in inconvenience in extending the number of sections, inconvenience in angle adjustment, inconvenience in installation and construction, and inconvenience in fixing due to the lack of clamping. This objective is achieved through the following technical solution.

[0004] A clamp-on bamboo-joint quick-connect tee connector is disclosed. The tee body is T-shaped, with quick-connect fittings at both ends and the top protruding port in the middle. The key structural design features quick-connect fittings located at the openings of the quick-connect ball seat at the top center of the tee body and at both ends of the tee body. The ball head at the other end of the quick-connect ball seat is press-fitted into the quick-connect ball head groove at one end of the ball head connector, with a first sealing ring at the connection point. The ball head connector serves as a universal joint between the quick-connect ball seat and the tee body. At least one ball head connector is provided between the tee body and the quick-connect ball seat, and the internal channel of the quick-connect ball seat communicates with the internal channel of the tee body through the ball head connector. The top protruding port in the middle of the tee body is the ball head groove of the valve body, and the quick-connect ball head at the other end of the ball head connector is press-fitted into the ball head groove of the tee body, with a second sealing ring at the connection point. Therefore, after the top port of the three-way valve body is convex in the middle and connected in series with ball head connectors as needed, it can finally be connected to the quick ball seat with pipe quick connector.

[0005] The main body of the three-way valve is rectangular. The bottom or at least one side of the main body has symmetrically arranged protruding lugs along its edges. One lug has a locking bolt with a threaded portion passing through the gap between the lugs. The end of the threaded portion of the locking bolt within the gap between the lugs may have a nut washer. This structure facilitates the use of the quick-connect tee by securing it with a clamp on the bottom or one side.

[0006] The ball joint groove of the valve body is omitted at the top center of the three-way valve body, and the quick-connect fitting is located at the protruding top center of the three-way valve body. The above is an embodiment of a three-way valve body structure with a clamp.

[0007] Two or more ball head connectors are provided between the ball head of the quick-connect ball seat and the ball head groove of the valve body in the middle of the top of the three-way valve body; after the quick-connect ball head at one end of the ball head connector and the quick-connect ball head groove of the other ball head connector are sequentially press-fitted together, the quick-connect ball head and quick-connect ball head groove at the ball head connectors at both ends are respectively connected to the ball head groove of the valve body of the three-way valve body and the ball head at the ball head seat of the ball head atomizing component.

[0008] The first sealing ring is disposed in the first sealing ring groove on the outer diameter of the ball head of the quick-connect ball seat, and the second sealing ring is disposed in the second sealing ring groove on the outer diameter of the quick-connect ball head at one end of the ball head connector.

[0009] The quick-connect fitting includes a fixing component and a connecting component. The connecting component has equidistantly spaced and protruding fixing tabs on one side of the pipe hole. These fixing tabs are interference-fitted into and confined at one end of the fixing component's hole. The outer diameter of the connecting component's pipe hole on the other side protrudes beyond the inner diameter of the fixing component's hole, allowing the connecting component to move within the fixing component. The inner diameter of the locking port formed by the fixing tabs within the fixing component has protruding sealing ribs. The ends of the fixing tabs within the fixing component extend beyond the fixing component and are inserted into the holes at both ends of the three-way valve body and the quick-connect ball seat. The fixing component is fastened and fixed to the valve body fastening ribs at the outer diameter of the holes at both ends of the three-way valve body and the ball seat fastening ribs at the outer diameter of the quick-connect ball seat's hole. The port face of the fixing component has equidistantly spaced arc-shaped holes. The above is a specific structural embodiment of a quick-connect fitting. It can also be fixed by a knob-type end cap, i.e., by connecting the internal thread of the end cap to the external thread of the hole.

[0010] The inner diameter of the connector's opening increases from the outside towards the sealing rib end. As the pipe is inserted into the connector's opening and sealed, the orifices at both ends of the three-way valve body and the orifice of the quick-connect ball seat are respectively provided with stepped inner diameters to limit the insertion of the pipe into the connector. Above the stepped inner diameter, the end of the connector's fixing clip abuts against the third sealing ring. The inner side of the sealing rib of the fixing clip is respectively provided with a steel plate. The aforementioned third sealing ring and the steel plate inside the fixing clip are provided as needed, so that the pipe is sealed through the third sealing ring or the sealing rib of the fixing clip after insertion. The steel plate inside the fixing clip prevents the pipe from being pulled out arbitrarily.

[0011] This utility model has a reasonable structural design, is easy to use, and has various forms and structures. In particular, it is convenient and quick to connect water pipes, has a wide range of applications, and is easy to promote and use. It is suitable for use as a bamboo-joint quick-connect tee with clamps, and is an improvement on similar products. Attached Figure Description

The quick-connect fittings are respectively located at the openings of one end of the quick-connect ball seat 3 at the top middle of the three-way valve body and the openings at both ends of the three-way valve body. The ball head at the other end of the quick-connect ball seat is press-fitted into the quick-connect ball head groove 202 at one end of the ball head connector 2, and a first sealing ring 6 is provided at the connection. The ball head connector serves as a universal joint between the quick-connect ball seat and the three-way valve body. At least one ball head connector is provided between the three-way valve body and the quick-connect ball seat. The internal channel of the quick-connect ball seat is connected to the internal channel of the three-way valve body through the ball head connector. The top protrusion in the middle of the three-way valve body is the valve body ball head groove 101. The quick-connect ball head 201 at the other end of the ball head connector is press-fitted into the valve body ball head groove of the three-way valve body, and a second sealing ring 7 is provided at the connection. The main body of the three-way valve body is rectangular. The bottom or at least one side of the main body of the three-way valve body is provided with symmetrical protruding side ears 102. One side ear is provided with a locking bolt 9 with a screw portion passing through the gap between the side ears. The end of the screw portion of the locking bolt in the gap between the side ears may be provided with a nut washer.

[0021] Two or more ball joint connectors are provided between the ball head of the quick-connect ball seat and the ball head groove of the valve body in the middle of the top of the three-way valve body; after the quick-connect ball head at one end of the ball joint connector is sequentially press-fitted with the quick-connect ball head groove of the other ball joint connector, the quick-connect ball head and quick-connect ball head groove at both ends of the ball joint connector are respectively connected to the valve body ball head groove of the three-way valve body and the ball head at the ball head seat of the ball head atomizing assembly. A first sealing ring is provided in the first sealing ring groove on the outer diameter of the ball head of the quick-connect ball seat, and a second sealing ring is provided in the second sealing ring groove on the outer diameter of the quick-connect ball head at one end of the ball joint connector.

[0022] The aforementioned quick-connect fittings include a fixing component 4 and a connecting component 5. The connecting component has equidistant and protruding fixing clips 501 on one side of the pipe hole. The fixing clips of the connecting component are interference-fitted into and limited to one end of the fixing component's hole. The outer diameter of the connecting component's pipe hole on the other side protrudes larger than the inner diameter of the fixing component's hole. The connecting component moves within the fixing component. The inner diameter of the locking port formed by the fixing clips in the fixing component is provided with protruding sealing ribs 5011. The ends of the fixing clips in the fixing component protrude from the fixing component and are inserted into the holes at both ends of the three-way valve body and the holes of the quick-connect ball seat. The fixing component is fastened and fixed to the valve body fastening ribs 103 on the outer diameter of the holes at both ends of the three-way valve body and the ball seat fastening ribs 301 on the outer diameter of the quick-connect ball seat's hole. The port ring surface of the fixing component is provided with equidistant arc-shaped holes. The inner diameter of the connector's pipe opening increases from the outside towards the sealing rib end. While the pipe is inserted into the connector's pipe opening and sealed, the orifices at both ends of the three-way valve body and the orifice of the quick-connect ball seat are respectively provided with stepped inner diameters to limit the insertion of the pipe into the connector.

[0023] like Figures 5-6 In the second embodiment shown, the ball head groove of the valve body is omitted at the middle top of the three-way valve body. The quick-connect pipe is set at the protruding pipe opening at the middle top of the three-way valve body. The fixing buckle end of the connector above the inner diameter of the step abuts against the third sealing ring 10.

[0024] In use, one or more ball joint connectors are provided between the ball head of the quick-connect ball seat and the ball head groove of the valve body in the middle of the top of the three-way valve body. After the quick-connect ball head at one end of one ball joint is press-fitted into the quick-connect ball head groove of another ball joint, the quick-connect ball heads and quick-connect ball head grooves at both ends of the ball joint are respectively connected to the ball head groove of the valve body of the three-way valve body and the ball head of the quick-connect ball seat. Finally, water pipes are inserted into the orifices on both sides of the three-way valve body and the orifice of the top quick-connect ball seat, and the pipe ends are respectively inserted into the orifices on both sides of the three-way valve body and the orifice of the top quick-connect ball seat. The quick-connect tee is then ready for use. When removing the water pipe, press the connector, and the water pipe can be pulled out.

[0025] In summary, this quick-connect tee is an upgraded design based on the specific usage environment required by the customer. Its key feature is that the number of universal joint sections can be extended according to actual needs. The multiple sections allow for a wider adjustable angle. During the initial pipe installation, there is no need to consider the consistency of a row. After the pipe is fixed, the angle can be quickly and easily adjusted by rotating the universal joint, thus saving time and effort. This avoids the situation where, in the past, when multiple nozzles were arranged over a long distance with different nozzle angles, it was necessary to repeatedly turn the nuts at both ends of the corresponding tee, which was time-consuming and laborious to adjust.
