Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a metal connector for building water heating pipelines. Background Art

[0002] Pipeline connectors are connecting tools between pipelines and are detachable connection points between pipes. They play an indispensable and important role in pipeline connections and are one of the main components of the pipeline network.

[0003] The pipe connectors currently on the market require multiple cumbersome steps to be performed when used. For example, the utility model with patent number CN221004146U requires the user to first align the pipes on both sides during installation, and then rotate and fix them to the connector. Subsequently, the user also needs to manually operate the upper ring sleeve and the lower sleeve to ensure that the two parts are correctly and firmly fixed in the corresponding positions to complete the entire connection process. A significant disadvantage of this design is that when the pipe cannot rotate freely for some reason, such as when the pipe is fixed or there are obstacles blocking it, the connection operation cannot be completed smoothly. This not only increases the difficulty of work, but may also affect work efficiency, and even cause connection failure in some emergency or special circumstances, thereby affecting the reliability and safety of the system.

[0006] The openings at both ends of the opening are of different sizes, and the opening at one end of the opening close to the middle of the ring in which the protrusions are arranged is smaller, so as to facilitate the clamping of the buckle bead.

[0007] Preferably, grooves matching the support rods are provided on both sides of the middle ring at the position of each support rod, so as to facilitate the inward movement of the support rods and prevent the middle ring from hindering the movement of the support rods.

[0008] Preferably, sealing rings are fitted between the two sides of the middle ring and the connector, and the sealing rings are used to enhance the sealing between the pipes.

[0009] Preferably, a slope is provided in the limiting groove, and when the connector needs to be installed or detached, it is only necessary to push the buckle ring to drive the slope to move so that the slope is above the buckle bead, so that the buckle bead can move up and down.

[0010] Preferably, each connector is provided with a plurality of thrust rings to prevent the water pipe from detaching from the connector when the water pipe is sleeved on the connector.

[0011] Preferably, an annular groove is provided on the outer side of one end of each connector close to the middle ring to facilitate the buckle bead to clamp the connector.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-4 The utility model provides a technical solution: a metal connector for building water heating pipes, including an intermediate ring 3, a plurality of connectors 1 are arranged on both sides of the intermediate ring 3, a plurality of protrusions 5 arranged in a ring are fixed on the outer side of each connector 1 at both ends of the intermediate ring 3, a retaining ring 8 is fixed on the end of the protrusion 5 away from the intermediate ring 3, and an opening 11 is opened in the middle position of each protrusion 5, a buckle bead 6 is built in each opening 11, a plurality of springs 9 are arranged between the protrusions 5, and each spring 9 rotates a circle There are support rods 10 inside, and the middle ring 3 divides the support rods 10 into two groups. A buckle 2 is fixed to the end of each group of support rods 10 away from the middle ring 3. Several sliders 13 are evenly arranged on the inner side of the buckle 2. The outer side of the sliders 13 is provided with a limited groove 14 on the buckle 2. The buckle 2 is pushed to make the buckle beads 6 active. At this time, the connector 1 can be inserted between the buckle beads 6, and then the buckle 2 is loosened. The buckle 2 is pushed back by the spring 9, and the buckle beads 6 are pushed downward by the buckle 2 to clamp the connector 1. The opening sizes of the two ends of the opening 11 are different. The opening of the opening 11 at the middle of the ring arranged near the protrusion 5 is smaller, which is convenient for clamping the buckle beads 6.

[0023] Furthermore, grooves matching the support rods 10 are provided on both sides of the middle ring 3 at the position of each support rod 10 to facilitate the support rods 10 to move inward and prevent the middle ring 3 from hindering the movement of the support rods 10 .

[0024] Furthermore, sealing rings 4 are fitted between the two sides of the middle ring 3 and the connector 1, and the sealing rings 4 are used to enhance the sealing between the pipes.

[0025] Furthermore, a slope is provided in the limiting groove 14. When the connector 1 needs to be installed or detached, the buckle ring 2 only needs to be pushed to drive the slope to move so that the slope is above the buckle bead 6, so that the buckle bead 6 can move up and down.

[0026] Furthermore, each connector 1 is provided with a plurality of thrust rings 7 to prevent the water pipe from being separated from the connector 1 when the water pipe is sleeved on the connector 1 .

[0027] Furthermore, an annular groove is provided on the outer side of one end of each connector 1 close to the middle ring 3 to facilitate the buckle bead 6 to clamp the connector 1 .

[0028] Working principle: When in use, first connect the pipe to the connector 1, then push the buckle 2, and several sliders 13 located in the buckle 2 cooperate with the slide groove 12 to limit the moving direction of the buckle 2 to prevent the buckle 2 from rotating. When the buckle 2 moves, it also drives the limit groove 14 and the support rod 10 to move until the limit groove 14 is directly above the buckle bead 6. At this time, the buckle bead 6 can move up and down in the opening 11, and then fit the gasket to both sides of the middle ring 3, and insert the connector 1 between the buckle beads 6, and then release the buckle 2. The buckle 2 moves to the initial position under the push of the spring 9. At this time, the limit groove 14 will leave the top of the buckle bead 6, and the buckle 2 will block the buckle bead 6, making it unable to move, and the bottom of the buckle bead 6 will jam the connector 1.

[0029] When the connector 1 needs to be removed, the buckle ring 2 can be pushed to make the buckle bead 6 active, and then the connector 1 can be pulled out. After the buckle ring 2 is released, the spring 9 will push the buckle ring 2 to return to its original position.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
