Description

Technical Field

[0001] This utility model relates to the technical field of pipe joints, and in particular to a quick-release wear-resistant pipe joint. Background Technology

[0002] In the field of industrial pipeline connections, traditional quick-release couplings generally suffer from problems such as cumbersome operation and insufficient sealing reliability. In existing technologies, some couplings rely on rigid structures for forced unlocking, which can easily lead to wear or jamming of the seals. Moreover, single-seal designs are prone to leakage under high-pressure or high-frequency disassembly and assembly conditions. At the same time, couplings lacking flexible linkage mechanisms require additional force or tools to complete the connection, resulting in low efficiency and difficulty in meeting the needs of chemical, metallurgical, and engineering machinery fields for rapid pipeline connection, stable sealing, and convenient maintenance. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this utility model is to propose a quick-release wear-resistant pipe joint. When two pipes are connected, the sealing structure can be quickly pushed open through the linkage design to open the channel. The operation is convenient and does not jam. The connection is stable and leak-proof. It automatically resets after disconnection. It is suitable for scenarios that require frequent disassembly and assembly, making the pipe connection fast and stable.

[0005] To achieve the above objectives, this utility model proposes a quick-release wear-resistant pipe joint, comprising: a pipe inner sliding shaft disposed within a first connecting pipe, the pipe inner sliding shaft being connected to the inner wall of the first connecting pipe via an inner sliding shaft spring; a first sliding shaft channel disposed within a second connecting pipe, a clamping head shaft being slidably mounted within the first sliding shaft channel via a clamping head spring; a convex head disposed within the inner wall of the second connecting pipe, the inner sidewall of the convex head having a first sealing ring groove and a second sealing ring groove, the end of the clamping head shaft having a first sealing ring seal adapted to the first sealing ring groove, and the outer ring of the first sealing ring seal having a second sealing ring seal adapted to the second sealing ring groove; a pusher disposed within the opening of the first connecting pipe, the pusher being fixed inside the first connecting pipe via an extension rod, the pusher contacting and sealing the pipe inner sliding shaft.

[0006] This utility model's quick-release wear-resistant pipe joint allows for rapid opening of the sealing structure and passage through a linkage design when two pipes are connected. It is easy to operate without jamming, provides a stable and leak-proof connection, and automatically resets after disconnection. It is suitable for scenarios that require frequent disassembly and assembly, making pipe connections both quick and stable.

[0007] In addition, the quick-release wear-resistant pipe joint proposed in the application may also have the following additional technical features:

[0008] Furthermore, the chuck shaft is provided with a second sliding cavity, and the push rod is slidably installed in the second sliding cavity by a push rod spring.

[0009] Furthermore, a connector is connected to the end of the push rod, and the shape of the connector is adapted to the shape of the inner groove of the push head.

[0018] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] The quick-release wear-resistant pipe joint of this utility model is described below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, the quick-release wear-resistant pipe joint of this utility model includes: an inner sliding shaft 15 is provided inside the first connecting pipe 1, and the inner sliding shaft 15 is connected to the inner wall of the first connecting pipe 1 through an inner sliding shaft spring 16.

[0021] The second connecting pipe 2 is provided with a first sliding shaft channel 4, and a clamping shaft 5 is slidably installed in the first sliding shaft channel 4 through a clamping spring 18.

[0022] The inner wall of the second connecting pipe 2 is provided with a convex head 14. The inner side wall of the convex head 14 is provided with a first sealing ring groove 12 and a second sealing ring groove 13. The end of the clamp shaft 5 is provided with a first sealing ring 10 that is adapted to the first sealing ring groove 12. The outer ring of the first sealing ring 10 is provided with a second sealing ring 11 that is adapted to the second sealing ring groove 13.

[0023] A pusher 3 is provided on the inner wall of the opening of the first connecting pipe 1. The pusher 3 is fixed inside the first connecting pipe 1 by an extension rod, and the pusher 3 contacts and seals with the sliding shaft 15 inside the pipe.

[0024] When the first connecting pipe 1 and the second connecting pipe 2 are axially connected, the pusher 3 acts as an active pusher, and its end contacts the clamp shaft 5 and applies a pushing force. The clamp shaft 5 overcomes the elastic force of the clamp spring 18 and retracts into the first sliding shaft channel 4, causing the first sealing ring 10 to disengage from the first sealing ring groove 12, and the second sealing ring 11 to disengage from the second sealing ring groove 13. The seal of the second pipe 2 is released, and the internal channel is opened.

[0025] At the same time, the convex head 14 of the second pipe contacts the inner sliding shaft 15 of the first pipe → applying a reverse thrust, the inner sliding shaft 15 compresses the inner sliding shaft spring 16, slides backward, and disengages from the contact sealing surface of the push head 3, thus opening the internal channel of the first pipe 1.

[0026] During the disconnection process, the docking thrust is removed, the clamp spring 18 pushes the clamp shaft 5 to extend, and the first sealing ring 10 and the second sealing ring 11 are re-embedded into the first sealing ring groove 12 and the second sealing ring groove 13, thus sealing the second pipeline.

[0027] In one embodiment of this application, the chuck shaft 5 is provided with a second sliding cavity 6, and the push rod 7 is slidably installed in the second sliding cavity 6 by a push rod spring 9.

[0028] Specifically, during docking, the pusher 3 of the first connecting pipe 1 pushes the push rod 7 to compress the push rod spring 9, causing it to slide within the second sliding cavity 6 and transmit the thrust to the clamp shaft 5. This drives the clamp shaft to overcome the elastic force of the clamp spring 18 and retract into the sliding shaft channel 4, thus separating and unlocking the sealing rings 10 and 11 from the annular groove. Upon disconnection, the push rod spring 9 and the clamp spring 18 rebound synchronously, and the push rod 7 and clamp shaft 5 return to their initial states. This design, through the sliding cavity guidance and spring linkage, achieves buffered transmission of docking force and precise control of the unlocking action, avoiding rigid contact damage to the sealing components and improving the stability and durability of the joint operation.

[0029] In one embodiment of this application, a connector 8 is connected to the end of the push rod 7, and the shape of the connector 8 is adapted to the shape of the inner groove of the push head 3.

[0030] Specifically, the external shape of the connector 8, such as bosses, tenons, hemispheres, etc., and the internal shape of the groove of the pusher 3, such as slots, mortises, concave spherical surfaces, etc., are geometrically interlocked to form a precise fit. When the first connecting pipe 1 and the second connecting pipe 2 are connected, the groove of the pusher 3 can quickly snap into the connector 8, ensuring that the axial thrust is transmitted to the push rod 7 without deviation along the center line, and avoiding jamming of the clamping shaft 5 or uneven wear of the sealing ring due to tilting under force.

[0031] In one embodiment of this application, the length of the circumference of the first sealing ring 10 is less than the length of the circumference of the second sealing ring 11.

[0032] Specifically, a stepped sealing structure is formed. During docking, the short ring edge is first embedded into the first sealing ring groove 12 for guidance and positioning, and the long ring edge is then embedded into the second sealing ring groove 13 to enhance the sealing depth. The graded sealing improves the anti-leakage capability, while avoiding excessive installation resistance caused by the simultaneous extrusion of the two rings, thus ensuring sealing reliability and ease of operation.

[0033] In one embodiment of this application, the first connecting pipe 1 is provided with an internal thread head 17 at its mating end, and the outer wall of the second connecting pipe 2 is provided with an external thread that mates with the internal thread head 17.

[0034] Specifically, the internal thread 17 at the mating end of the first connecting pipe 1 and the external thread at the mating end of the second connecting pipe 2 form a threaded mating structure, and mechanical locking is achieved by rotating and tightening during mating.

[0035] In actual use, when the first connecting pipe 1 and the second connecting pipe 2 are axially connected, the pusher 3 acts as the active pusher. The pusher 3 of the first connecting pipe 1 pushes the push rod 7 to compress the push rod spring 9, causing it to slide in the second sliding cavity 6 and transmit the thrust to the clamp shaft 5. Its end contacts the clamp shaft 5 and applies the thrust. The clamp shaft 5 overcomes the elastic force of the clamp spring 18 and retracts into the first sliding shaft channel 4, causing the first sealing ring 10 to disengage from the first sealing ring groove 12, and the second sealing ring 11 to disengage from the second sealing ring groove 13. The seal of the second pipe 2 is released, and the internal channel is opened.

[0036] In summary, the quick-release wear-resistant pipe joint of this utility model embodiment can quickly push open the sealing structure and open the channel when two pipes are connected through the linkage design. It is easy to operate without jamming, the connection is stable and leak-proof, and it automatically resets after disconnection. It is suitable for scenarios that require frequent disassembly and assembly, making pipe connection both fast and stable.
