DETAILED DESCRIPTION

[0021] 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 of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 5 A long-life anti-corrosion and anti-rust straight-through joint comprises a first connection part 1 and a second connection part 2, a conical block 3 is fixedly mounted on one end of the second connection part 2, the maximum diameter of the conical block 3 is larger than the end diameter of the second connection part 2, a slot 4 for inserting the conical block 3 is opened at one end of the first connection part 1, a fixing ring 5 is fixedly mounted on the surface of the second connection part 2, and the fixing ring 5 has the same diameter as the first connection part 1;

[0024] The surface of the first connecting part 1 is symmetrically provided with through openings, in which an insertion rod 6 is slidably inserted, a trapezoidal locking block 7 is fixedly installed at the bottom end of the insertion rod 6, the insertion rod 6 is connected to the first connecting part 1 through a telescopic component, the telescopic component includes a first telescopic spring 8 sleeved on the insertion rod 6, a U-shaped block 9 is fixedly installed at one end of the insertion rod 6 located outside, and the two ends of the first telescopic spring 8 are respectively fixedly connected to the U-shaped block 9 and the first connecting part 1;

[0025] First, the first connecting part 1 and the second connecting part 2 are fixedly connected to the ends of the two metal water pipes to be connected, and then the conical block 3 at the end of the second connecting part 2 is controlled to be inserted into the slot 4 opened at the end of the first connecting part 1. The inclined surfaces of the two locking blocks 7 will slide in contact with the inclined surfaces of the conical block 3. Under the action of the inclined surface pressure, the two locking blocks 7 will move away from each other in the horizontal direction until the conical block 3 moves to the end and abuts against the groove wall of the slot 4. At this time, the end at the opening of the first connecting part 1 will abut against the surface of the fixing ring 5, and the locking block 7 will no longer abut against the inclined surface of the conical block 3. The pressing force of the conical block 3 on the locking block 7 disappears, and the conical block 3 will quickly move and reset under the elastic potential energy of the first telescopic spring 8, thereby abutting against the end face of the larger diameter of the conical block 3, thereby completing the connection between the first connecting part 1 and the second connecting part 2. When disassembling, it is only necessary to control the two insertion rods 6 to move away from each other from the outside so that the two locking blocks 7 no longer abut against the end of the conical block 3, which is convenient and quick.

[0026] A limiting assembly is provided at the U-shaped block 9, and the limiting assembly is used to limit the movement of the insertion rod 6. The limiting assembly includes an L-shaped connecting plate 10, a locking rod 11 and a second telescopic spring 12. A rotating shaft is installed in the U-shaped block 9 for horizontal rotation. The connecting plate 10 is fixedly sleeved on the rotating shaft, and a through hole is opened at one end away from the rotating shaft. The locking rod 11 is slidably inserted in the through hole, and a fixed block is fixedly installed at one end. The two ends of the second telescopic spring 12 are fixedly connected to the fixed block and the connecting plate 10, respectively. The surface of the fixing ring 5 is symmetrically provided with a locking groove 13 for inserting the end of the locking rod 11;

[0027] When the conical block 3 is pushed into the slot 4, it is necessary to align the positions of the two locking grooves 13 and the two connecting plates 10. When the first connecting part 1 and the second connecting part 2 are connected, the two connecting plates 10 are rotated. When the two connecting plates 10 are rotated to a horizontal state, the ends of the two locking rods 11 will correspond to the positions of the two locking grooves 13 respectively, and then the ends of the two locking rods 11 are controlled to be inserted into the two locking grooves 13 respectively, so that the restriction on the two insertion rods 6 can be completed. The insertion rod 6 cannot move at this time, which improves the stability of the connection between the first connecting part 1 and the second connecting part 2. When disassembly is required, it is necessary to first pull the two locking rods 11 in a direction away from the fixing ring 5 so that the ends of the two locking rods 11 are respectively moved out of the two locking grooves 13. Only then can the restriction on the two insertion rods 6 be released, and then the two insertion rods 6 are controlled to move away from each other so that the locking block 7 no longer contacts the end of the conical block 3, and the first connecting part 1 and the second connecting part 2 can be disassembled.

[0028] A straight rod is symmetrically fixedly installed on the surface of the first connecting part 1, and a U-shaped seat 14 is fixedly installed on one end of the straight rod away from the first connecting part 1, and the two U-shaped seats 14 are respectively located on the rotation paths of the two connecting plates 10;

[0029] When the connecting plate 10 is controlled to rotate until it rotates to abut against the U-shaped seat 14, the connecting plate 10 is in a horizontal state, and there is no need to manually spend time to adjust the connecting plate 10 to a horizontal state.

[0030] A semi-annular sealing strip 16 is fixedly mounted on the surface of the insertion rod 6 located in the slot 4 via an L-shaped connecting rod 15;

[0031] The sealing strip 16 will move with the insertion rod 6. When the end of the conical block 3 abuts against the wall of the slot 4, the two sealing strips 16 will also quickly move and reset during the movement and reset of the insertion rod 6, and abut against each other, thereby pressing and sealing the contact surface between the conical block 3 and the slot 4 to prevent water from flowing out of the contact surface when water leaks.

[0032] In the utility model, the first connecting part 1 and the second connecting part 2 are first fixedly connected to the ends of the two metal water pipes to be connected, and then the conical block 3 at the end of the second connecting part 2 is controlled to be inserted into the slot 4 opened at the end of the first connecting part 1. The inclined surfaces of the two locking blocks 7 will slide in contact with the inclined surfaces of the conical blocks 3. Under the action of the inclined surface pressure, the two locking blocks 7 will move away from each other in the horizontal direction until the conical block 3 moves to the end and abuts against the groove wall of the slot 4. At this time, the end of the opening of the first connecting part 1 will abut against the surface of the fixing ring 5, and the locking block 7 will no longer abut against the inclined surface of the conical block 3. The conical block 3 gives the locking block 7 a resistance When the pressure force disappears, the conical block 3 will quickly move and reset under the elastic potential energy of the telescopic component, thereby abutting against the end face of the conical block 3 with a larger diameter, thereby completing the connection between the first connecting part 1 and the second connecting part 2. Water will only flow in the first connecting part 1 and the second connecting part 2 and will not contact the structure in the slot 4, thereby preventing the locking block 7, the plug rod 6 and other connectors from being corroded or rusted due to long-term contact with water, thereby improving the service life and preventing the connection from being loosened due to water leakage. When disassembling, you only need to control the two plug rods 6 to move away from each other from the outside so that the two locking blocks 7 no longer abut against the ends of the conical block 3, which is convenient and quick.

[0033] 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.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
