Description

Technical Field

[0001] This application belongs to the field of connector technology, specifically relating to an adjustable angle connector. Background Technology

[0002] In actual use, due to the tolerance of the client's pipeline length, the angle of the existing L-type connector may not meet the actual connection requirements after leaving the factory. In this case, in order to connect the pipeline quickly and easily, the client will loosen the nut and forcefully rotate the connector to make it rotate to the appropriate angle for connection. However, for connectors with a sealing coating, this method will cause the solidified sealant coating to be rotated and squeezed after the connection angle is changed by forcefully rotating the connector, which will lead to the failure of the seal. When a pressure medium passes through the middle of the pipe joint, gas or liquid medium will leak outward through the thread gap. Utility Model Content

[0003] This application provides an adjustable angle connector, which solves the problem of poor sealing effect caused by the failure of the sealing coating due to compression after the connector is adjusted for connection angle.

[0004] The technical solution adopted in this application is as follows:

[0005] An adjustable angle connector includes an interface end adapted for threaded connection, the outer wall surface of the interface end being provided with connecting threads, the connector further including a nut, the nut being rotatably connected to the interface end via the connecting threads, an extension end of the interface end being provided with a communication port for a medium to pass through, and the connector further including a sealing component movably connected to the interface end, the sealing component being located on the side closer to the communication port relative to the nut, and the sealing component abutting against the nut.

[0006] Preferably, the sealing assembly includes an elastic sealing ring, the inner wall of which is provided with a sealing thread that mates with the connecting thread, so that the elastic sealing ring is rotatably connected to the interface end.

[0007] Preferably, the elastic sealing ring includes a connecting portion with the sealing thread and a reinforcing portion disposed along the axial direction of the elastic sealing ring, wherein the reinforcing portion is at least disposed on the side of the elastic sealing ring near the nut and abuts against the nut.

[0008] Preferably, the connecting part and the reinforcing part are integrally formed.

[0009] Preferably, a clearance is provided between the reinforcing part and the connecting thread.

[0010] Preferably, the sealing assembly further includes a rigid sealing ring disposed radially outside the elastic sealing ring, and the rigid sealing ring abuts against the nut.

[0011] Preferably, the axial height of the elastic sealing ring is greater than the axial height of the rigid sealing ring.

[0012] Preferably, the elastic sealing ring and the rigid sealing ring are an integral structure.

[0013] Preferably, the diameter of the sealing assembly is smaller than the diameter of the nut.

[0014] Preferably, the connecting thread is provided with sealant.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0016] (1) This application sets a nut that is rotatably connected to the interface end of the connector, so that the nut can be rotated and loosened when the angle of the connector cannot meet the actual connection angle, thereby adjusting the angle of the connector. At the same time, a sealing component that is movably connected is set at the interface end. When the angle of the connector needs to be adjusted, the sealing component is moved after the nut is loosened, so that the sealing component always abuts against the nut. The nut presses the sealing component to achieve the sealing of the interface end, preventing the medium from seeping out or escaping through the gap of the connecting thread.

[0017] Meanwhile, since the sealing component and the interface are movably connected and have a detachable assembly relationship, if the connector fails or cannot be used again, the sealing component can be removed and reused, which helps to reduce the cost of connector replacement and improve the utilization rate of the sealing component.

[0018] (2) The joint is sealed by setting an elastic sealing ring. The flexible deformation of the elastic sealing ring enables it to form a good sealing effect under the pressure of the nut. The elastic sealing ring is provided with a sealing thread, so that the elastic sealing ring can be directly connected by rotation to achieve a sealing connection with the connecting thread. On the basis of end face sealing between the elastic sealing ring, the nut and the interface end, it can also achieve radial sealing with the interface end. At the same time, compared with the method of directly using a sealing ring with a smooth inner wall for sealing, the connection of the elastic sealing ring with a sealing thread is beneficial to improving the connection position stability of the elastic sealing ring.

[0019] (3) By setting a connecting part in the elastic sealing ring, a threaded connection between it and the joint is achieved. At the same time, a reinforcing part is set to provide deformation space for the elastic sealing ring under pressure. Since the elastic sealing ring is threadedly connected to the joint, if the entire elastic sealing ring is threadedly connected to the joint, the elastic sealing ring cannot effectively deform after being squeezed by the nut pressure due to its connection limit. The part extending outward from the connection position will deform more. Over time, the elastic sealing ring is prone to damage, which is not conducive to its stable use. Or, if the connection position deforms under force and the pressure is large, it may cause the elastic sealing ring to partially separate or shift from the connecting thread, affecting the sealing effect.

[0020] Therefore, by providing a sealing thread only at the connection part and an additional reinforcing part without a sealing thread in its axial direction, the reinforcing part and the connecting thread are not locked together. The reinforcing part is located on the nut side and abuts against the nut. When the joint is connected, the reinforcing part is in direct contact with the nut and is under pressure. Its deformation will not cause the above situation, which is conducive to the long-term effective sealing of the elastic sealing ring.

[0021] (4) By further setting a rigid sealing ring, a double seal is formed in conjunction with an elastic sealing ring. The elastic sealing ring is connected to the connecting thread for radial limiting seal, and the rigid sealing ring abuts against the nut to achieve end face seal. Since the rigid sealing ring will not deform when subjected to nut pressure, it can effectively ensure the overall positional stability of the sealing component and avoid the elastic sealing ring from shifting when subjected to large force, resulting in insufficient sealing. This is beneficial to improving the sealing effect.

[0022] (5) By setting the height of the elastic sealing ring to be relatively high, the elastic sealing ring will be subjected to pressure first when it is under pressure. As the elastic sealing ring is compressed, it will be compressed until it is level with the height of the rigid sealing ring. Then the nut will finally contact the rigid sealing ring. Since the rigid sealing ring will not be compressed and deformed under pressure, the elastic sealing ring will not be excessively deformed and the connection will be unstable. This is beneficial to the overall connection and positioning stability of the sealing assembly. Attached Figure Description

[0034] This application provides an adjustable angle connector, such as Figs. 1 to 3 As shown, the connector 1 includes an interface end 100 adapted for threaded connection, the outer wall surface of the interface end 100 is provided with a connecting thread 110, the connector 1 also includes a nut 200, the nut 200 is rotatably connected to the interface end 100 through the connecting thread 110, the extended end of the interface end 100 is provided with a communication port 120 for the medium to pass through, the connector 1 also includes a sealing component 300 movably connected to the interface end 100, the sealing component 300 is located on the side closer to the communication port 120 relative to the nut 200, and the sealing component 300 abuts against the nut 200.

[0035] This application provides a nut 200 that is rotatably connected to the interface end 100 of the connector 1. This allows the nut 200 to be rotated and loosened when the angle of the connector 1 cannot meet the actual connection angle, thereby adjusting the angle of the connector 1. At the same time, a movable sealing component 300 is provided at the interface end 100. When it is necessary to adjust the angle of the connector 1, the sealing component 300 is moved after the nut 200 is loosened, so that the sealing component 300 always abuts against the nut 200. The nut 200 presses the sealing component 300, thereby sealing the interface end 100 and preventing the medium from seeping or escaping through the gaps in the connecting threads 110.

[0036] Meanwhile, since the sealing component 300 and the interface end 100 are movably connected, the sealing component 300 and the interface end 100 are detachable. If the connector 1 fails or cannot be used in other ways, the sealing component 300 can be removed separately for reuse, which helps to reduce the replacement cost of the connector 1 and improve the utilization rate of the sealing component 300.

[0037] In one embodiment, such as Fig. 2 , Fig. 3As shown, the sealing assembly 300 includes an elastic sealing ring 310, the inner wall of which is provided with a sealing thread 311 that mates with the connecting thread 110, so that the elastic sealing ring 310 is rotatably connected to the interface end 100.

[0038] The joint 1 is sealed by setting an elastic sealing ring 310. The flexible deformation of the elastic sealing ring 310 enables it to form a good sealing effect under the pressure of the nut 200. A sealing thread 311 is provided on the elastic sealing ring 310, so that the elastic sealing ring 310 can directly achieve a sealing connection by rotating with the connecting thread 110. In addition to the end face sealing between the elastic sealing ring 310, the nut 200, and the interface end 100, it can also achieve radial sealing with the interface end 100. At the same time, compared with the method of directly using a sealing ring with a smooth inner wall for sealing, the connection with the sealing thread 311 is beneficial to improving the connection position stability of the elastic sealing ring 310.

[0039] Furthermore, the elastic sealing ring 310 includes a connecting portion 312 with the sealing thread 311 and a reinforcing portion 313 arranged in the axial direction of the elastic sealing ring 310. The reinforcing portion 313 is at least disposed on the side of the elastic sealing ring 310 near the nut 200 and abuts against the nut 200.

[0040] By providing a connecting part 312 to the elastic sealing ring 310, a threaded connection between it and the connector 1 is achieved. Simultaneously, a reinforcing part 313 is provided to allow for deformation space under pressure. Since the elastic sealing ring 310 is threaded to the connector 1, if the entire elastic sealing ring 310 is threaded to the connector 1, under the pressure of the nut 200, the connection point will be limited, preventing effective deformation. The portion extending outward from the connection point will deform more significantly. Over time, this can easily damage the elastic sealing ring 310, hindering its stable use. Alternatively, if the connection point deforms under pressure, it may partially detach or shift from the connecting thread 110, affecting the sealing effect.

[0041] Therefore, by providing a sealing thread 311 only in the connecting part 312 and an additional reinforcing part 313 without a sealing thread 311 in its axial direction, the reinforcing part 313 and the connecting thread 110 are not locked together. The reinforcing part 313 is located on the nut 200 side and abuts against the nut 200. When the joint 1 is connected, the reinforcing part 313 is in direct contact with the nut 200 and is compressed. Its deformation will not be as described above, which is beneficial to the long-term effective sealing of the elastic sealing ring 310.

[0042] Preferably, the connecting portion 312 and the reinforcing portion 313 are integrally formed. Integrating the connecting portion 312 and the reinforcing portion 313 helps ensure the sealing stability of the overall structure of the elastic sealing ring 310, preventing the reinforcing portion 313 from shifting under stress, thereby improving the overall structural positional stability of the elastic sealing ring 310 under stress. Even if deformation occurs, it will not affect the overall sealing effect.

[0043] Preferably, a clearance gap 314 is provided between the reinforcing part 313 and the connecting thread 110.

[0044] It should be noted that the clearance 314 mentioned here means that the reinforcing part 313 does not need to extend radially to abut against the connecting thread 110. When the reinforcing part 313 is compressed, it will extend into the clearance 314 when it deforms, preferentially filling the space of the clearance 314. This helps to reduce the deformation of the connecting part 312 and can achieve a good sealing effect between the clearance 314 and the outside.

[0045] In one embodiment, such as Fig. 2 , Fig. 3 As shown, the sealing assembly 300 further includes a rigid sealing ring 320 disposed radially outside the elastic sealing ring 310, and the rigid sealing ring 320 abuts against the nut 200.

[0046] By further setting a rigid sealing ring 320, a double seal is achieved in conjunction with an elastic sealing ring 310. The elastic sealing ring 310 is connected to the connecting thread 110 for radial limiting seal, and the rigid sealing ring 320 abuts against the nut 200 to achieve end face seal. Since the rigid sealing ring 320 does not deform when subjected to the pressure of the nut 200, it can effectively ensure the overall positional stability of the sealing assembly 300, and prevent the elastic sealing ring 310 from shifting under large force, resulting in insufficient sealing, which is conducive to improving the sealing effect.

[0047] Preferably, the axial height of the elastic sealing ring 310 is greater than the axial height of the rigid sealing ring 320.

[0048] By setting the height of the elastic sealing ring 310 to be relatively high, when under pressure, the elastic sealing ring 310 is the first to be subjected to pressure. As the elastic sealing ring 310 is gradually compressed, when it is compressed to the same height as the rigid sealing ring 320, the nut 200 finally contacts the rigid sealing ring 320. Since the rigid sealing ring 320 will not be compressed and deformed under pressure, the elastic sealing ring 310 is prevented from being over-deformed and the connection is unstable, which is beneficial to the overall connection and limiting stability of the sealing assembly 300.

[0049] Preferably, the elastic sealing ring 310 and the rigid sealing ring 320 are an integral structure. Specifically, the elastic sealing ring 310 and the rigid sealing ring 320 can be vulcanized into a whole to achieve the overall structural stability of the sealing assembly 300. This ensures that when the rigid sealing ring 320 is compressed, its position remains unchanged, while the elastic sealing ring 310, which is integrated with it, will not continue to be compressed and will not shift. This also helps to stabilize the relative position between the elastic sealing ring 310 and the rigid sealing ring 320, avoiding gaps between the elastic sealing ring 310 and the rigid sealing ring 320 that would result from separate connections, thus improving the sealing effect of the sealing assembly 300.

[0050] In one embodiment, the diameter of the sealing component 300 is smaller than the diameter of the nut 200. With a smaller diameter, the sealing component 300 has a smaller bearing surface when the nut 200 compresses it. Under pressure, it is less prone to dispersion and more easily deforms to achieve a good sealing effect.

[0051] In one embodiment, a sealant is provided at the connecting thread 110. The sealant enhances the coating's sealing effect, and in conjunction with the sealing assembly 300, further improves the sealing reliability of the joint 1.

[0052] It should be noted that the elastic sealing ring in this application can be any existing technology, such as an O-ring or a lip seal.

[0053] For any parts not mentioned in this application, existing technologies may be used or referenced.
