DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 , a large-flow card sleeve ball valve manifold lower assembly quick-connect structure, including a manifold main body 1 and multiple floor heating pipes 4, multiple branch pipes 5 are fixedly connected to the bottom of the manifold main body 1, and a ball valve joint body 2 is installed under each branch pipe 5, and a first sealing ring 18 is fixedly installed in the branch pipe 5. An annular groove 20 is opened on the ball valve joint body 2, each branch pipe 5 is respectively connected to multiple bending rods 16 through multiple first springs, and one end of each bending rod 16 is fixedly connected to a clamping block 19, and each ball valve joint body 2 is fixedly connected to a second sealing ring 14 for connecting the corresponding floor heating pipe 4, and a circular ring 6 is sleeved on the outside of each branch pipe 5, and a fixing ring 9 is sleeved on the outside of each floor heating pipe 4. The inner wall of each fixing ring 9 is fixedly connected to a rubber ring 15, and a fixing rod 10 is fixedly provided on the fixing ring 9. The fixing rod 10 is connected to the corresponding circular ring 6 through a bolt 8, and each circular ring 6 is provided with a sliding assembly.

[0023] Each sliding assembly includes a plurality of moving blocks 12 fixedly mounted on the circular ring 6, each moving block 12 is provided with an opening 17 with a right-angled trapezoidal cross-section, one end of each bending rod 16 is in contact with the oblique inner wall of the corresponding opening 17, and each branch pipe 5 is provided with a plurality of sliding grooves for connecting the moving blocks 12, and the upper inner wall of each sliding groove is fixedly connected to a second spring 13, and the second spring 13 is fixedly connected to the moving block 12. When the external force applied to the circular ring 6 is removed, under the elastic force of the plurality of second springs 13, the plurality of moving blocks 12 will simultaneously move up along the corresponding sliding grooves, and the oblique inner walls of each opening 17 will move against the end faces of the corresponding bending rods 16, thereby causing the bending rods 16 and the branch pipe 5 to slide relative to each other, and the bending rods 16 extend toward the interior of the branch pipe 5, and the first spring is deformed.

[0024] Each ring 6 is provided with a plurality of threaded holes 11, which are arranged in a circular array. The surface of each branch pipe 5 is provided with a plurality of slots. One end of the bolt 8 is passed through the fixing rod 10 and is threadedly connected to the corresponding threaded hole 11, and one end of the bolt 8 is inserted into the slot, which can effectively prevent the ring 6 and the fixing rod 10 from sliding relative to the branch pipe 5. The lower end surface of each branch pipe 5 is fixedly connected to two positioning rods 3, and the end surface of each positioning rod 3 is in contact with the surface of the ball valve joint body 2. Each fixing rod 10 is fixed to the lower end surface of the branch pipe 5. There are two support bars 7 fixedly connected to the top, and the surface of each support bar 7 is in contact with the surface of the ball valve joint body 2. When the upper end surface of the ball valve joint body 2 is in close contact with the inner wall of the first sealing ring 18, the end faces of the two positioning rods 3 will be in contact with the surface of the ball valve joint body 2. The positioning rods 3 have a certain positioning effect on the installation of the ball valve joint body 2. When the surfaces of each support bar 7 are in contact with the surface of the ball valve joint body 2, one end of the bolt 8 passes through the fixing rod 10 and can be accurately docked with the threaded hole 11 to facilitate the locking of the ring 6.

[0025] In the present invention, during installation, first push the ring 6 downward, then insert the upper end of the ball valve joint body 2 into the corresponding branch pipe 5 until the upper end surface of the ball valve joint body 2 is tightly attached to the inner wall of the first sealing ring 18, then remove the external force applied to the ring 6, and under the elastic force of multiple second springs 13, multiple moving blocks 12 will move up along the corresponding slide grooves at the same time, and the inclined inner walls of each opening 17 will move against the end faces of the corresponding bending rods 16, thereby causing the bending rods 16 and the branch pipe 5 to slide relative to each other, and the bending rods 16 extend toward the inside of the branch pipe 5. Since one end of each first spring is fixedly connected to the corresponding bending rod 16 and the other end is fixedly connected to the branch pipe 5, the first spring is deformed, and each clamping block 19 will be clamped into the inside of the annular groove 20 after moving.

[0026] After that, place the fixing ring 9 under the ball valve joint body 2, and then pass one end of the floor heating pipe 4 through the fixing ring 9 and insert it into the lower end of the ball valve joint body 2. During this process, the surface of the floor heating pipe 4 will be tightly attached to the inner wall of the rubber ring 15 until the surface of the floor heating pipe 4 is tightly attached to the inner wall of the second sealing ring 14. At this time, there is an annular groove (not shown) on the surface of the floor heating pipe 4 and the rubber ring 15. The rubber ring 15 will be stuck into the inside of the annular groove and tightly attached to the rough inner wall of the annular groove. Finally, one end of the bolt 8 passes through the fixing rod 10 and is threadedly connected to the corresponding threaded hole 11, and one end of the bolt 8 is stuck into the inside of the card groove, so that the floor heating pipe 4, the ball valve joint body 2 and the branch pipe 5 can be firmly connected together, and the floor heating pipe 4, the ball valve joint body 2 and the branch pipe 5 can be quickly connected. Only one bolt 8 is needed to achieve the overall locking. The operation is relatively simple and quick, which is conducive to the quick connection of the branch pipe 5 and the floor heating pipe 4, and the assembly efficiency is high.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
