Detailed Description
When the locking pipeline interface is connected with a pipeline, the sealing ring and the locking structure are arranged at the interface to be used as a locking connecting mechanism, so that the pipeline interface does not need to be welded or glued and other fixed connecting modes during connection, and has anti-seismic and anti-tensile properties.
Example 1: with reference to fig. 1, a sealing concave ring [4] is arranged in a connector of the existing water pipe connector [1] and is used for installing a sealing ring [6], and a blocking step [2] can be arranged in an outer thread [3] of the water pipe connector [1] to prevent a locking nut [8] from being excessively screwed; a locking nut (8) with a locking step (10) at the end is arranged, an inner thread (11) is arranged on the inner wall of the locking nut (8), an outer thread (3) is arranged at the joint of the water pipe joint (1) and is matched with the inner thread, and the outer wall of the locking nut (8) can be square or round; the locking sleeve [7] provided with a circular ring [13] as a circular cylinder [12] with a wedge-shaped outer wall longitudinal section at one side of the body (namely the inner wall of the locking sleeve [7] is straight, the outer wall is a wedge-shaped with one end combined with the body [13] and the other end is large), the locking sleeve [7] is preferably made of a flexible and elastic material, and the friction coefficient is preferably large. When the water pipe joint is installed, the sealing ring [6] is installed in the sealing concave ring [4], the water pipe [5] is inserted into the sealing concave ring [4] and the sealing ring [6] in the water pipe joint [1] at a proper distance, then the wedge-shaped circular cylinder [12] of the locking sleeve [7] is inserted into a gap between the water pipe [5] and the water pipe joint [1], and finally when the locking nut [8] is screwed up with the water pipe joint [1], the locking sleeve [7] is further pushed into the gap between the water pipe [5] and the water pipe joint [1] by the locking step [10] of the locking nut [8], so that the water pipe [5] is tightly combined with the water pipe joint [1], the water pipe [5] is difficult to slip or break loose from the water pipe joint [1] under high pressure, and the locking nut [8] and the locking sleeve [7] form a locking structure. The friction coefficient of the outer wall of the water pipe [5] and the inner wall of the interface of the water pipe interface [1] is preferably as large as possible. After the water pipe is installed, the water pipe [5] and the water pipe connector [1] are sealed by the sealing ring [6] to prevent water flow in the pipe from leaking, and the water pipe [5] and the water pipe connector [1] are locked by the locking step [10] of the locking nut [8] and the locking sleeve [7] to prevent the water pipe [5] from measuring the slippage from the water pipe connector [1 ]. Meanwhile, because the water pipe connector [1] is not fixedly connected with the water pipe [5] any more, when the connector is slightly loosened and slides, the sealing ring [6] still can play a good sealing effect and can not leak water, and the connector can not leak water due to expansion and contraction caused by heat and contraction of the fixture of the pipe network or vibration until the connector is loosened, so that the performance of the pipe network is better.
Further, referring to fig. 2, in this embodiment, the sealing concave ring [4] in the water pipe connector [1] may also be disposed on the outer wall of the water pipe [5], and during installation, the sealing ring [6] is first sleeved in the sealing concave ring [4], and the water pipe [5] and the sealing ring [6] are inserted into the water pipe connector [1] at the same time by a proper distance.
Further, with reference to fig. 3 and 4, in this embodiment, an opening [15] shown in fig. 3 is processed at the interface of the water pipe connector [1], and a wedge-shaped ring [17] shown in fig. 4, which is thick at the top and thin at the bottom (i.e., thin at the middle and thick at the outer end), is arranged in the lock nut [8] (the wedge-shaped ring [17] can also be processed into a whole with the inner wall of the lock nut [8], so that the aperture at the port of the inner cavity of the lock nut [8] is smaller than that at the middle part, and at this time, the wedge-shaped ring [17] can prevent the lock nut [8] from being completely sleeved at the interface of the. When the locking screw cap [8] is screwed down, the wedge-shaped ring [17] directly compresses each piece at the interface of the water pipe interface [1] of the opening inwards with the outer wall of the water pipe [5], so that the fastening effect is better.
Furthermore, when the friction coefficient between the inner wall of the water pipe connector (1) and the outer wall of the water pipe (5) is large enough to effectively prevent the water pipe (5) from slipping, the locking sleeve (7) can be omitted.
Furthermore, with reference to fig. 5, more than one raised transverse edge [16] can be transversely arranged in the pipe wall between the openings [15] at the interface of the water pipe interface [1], so that the friction coefficient between the inner wall of the interface of the water pipe interface [1] and the outer wall of the water pipe [5] is increased, and the water pipe [5] is more difficult to slip from the water pipe interface [1 ].
Furthermore, in the embodiment, the sealing ring [6] and the locking sleeve [7] can also be made of elastic materials, so that the sealing ring [6] and the locking sleeve [7] can be tightly stretched on the outer wall of the water pipe [5], the sealing ring [6] and the locking sleeve [7] cannot easily slide on the outer wall of the water pipe or the outer wall of the water pipe [5], and the sealing concave ring [4] can be omitted according to specific conditions.

In the embodiment, the inner wall of the sealing sheath [18] and the outer wall of the water pipe [5] can be processed into hydrophobic surfaces, so that water flow in the pipe is more difficult to leak from the inner wall of the sealing sheath [18] and the outer wall of the water pipe [5], and the sealing effect is improved.
