Flexible pipe tools, due to their flexibility, can be used in a variety of water transport scenarios. In some water transport needs, openings are made at multiple locations on the flexible hose, and branch pipes are installed at the opening locations to meet the water transport requirements.

[0003] However, the relevant technology has at least one of the following problems: the branch pipe in the prior art includes a fixed base set on the pipe and a diversion pipe fitting outside the pipe. The fixed base and the diversion pipe fitting are fixed by a threaded connection. However, the threaded connection is prone to rotation, which causes the connection between the diversion pipe fitting and the base to loosen, resulting in water leakage. Utility Model Content

[0004] The technical problem solved by this utility model is that the branch pipe in the prior art includes a fixed base set on the pipe and a diversion pipe fitting outside the pipe. The fixed base and the diversion pipe fitting are fixed by a threaded connection. However, the threaded connection is prone to rotation, which causes the connection between the diversion pipe fitting and the base to loosen, resulting in water leakage.

[0005] To address the aforementioned problems, this utility model provides a quick-install pipe fitting for water supply pipelines, comprising: a base assembly including an upper base and a lower base, wherein a mating post is formed at the upper end of the lower base, and an external thread is provided on the outer side of the mating post; a mating groove is formed in the middle of the upper base, and an internal thread matching the external thread is provided on the inner side of the mating groove; an anti-reverse assembly comprising a first tooth and a second tooth that mesh with each other, wherein the first tooth is located on the outer side of the mating post, and the second tooth is located on the inner side of the mating groove; wherein, when the upper base and the lower base are fixedly clamped to the pipe wall of the water supply pipeline by a threaded connection, the first tooth and the second tooth mesh with each other to prevent the upper base and the lower base from rotating; and a branch pipe fitting fixedly disposed on the base assembly.

[0006] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the interlocking structure of the first and second teeth and the synergistic effect of the threaded pair keep the pipe clamping force constant, preventing rotational loosening between the upper and lower bases. This anti-retraction mechanism takes effect automatically during assembly, requiring no manual adjustment, and significantly improves the installation reliability of branch pipe fittings.

[0007] In one embodiment of this utility model, the first tooth portion includes a plurality of anti-retraction tooth protrusions evenly distributed along the outer side of the mating post, and the anti-retraction tooth protrusions are located at the upper end of the external thread; the second tooth portion includes a plurality of mating tooth protrusions evenly distributed along the inner side of the mating groove, and the mating tooth protrusions are located at the upper end of the internal thread.

[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution uses a mechanical interlocking structure between the toothed protrusion and the groove to add rigid limiting on the basis of threaded connection. It does not require the addition of independent anti-loosening parts and achieves the anti-loosening function under the same installation operation steps. At the same time, the uniform distribution design avoids tooth deformation failure caused by local stress concentration.

[0009] In one embodiment of this utility model, the branch fitting and the base assembly are detachably connected.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution, through its detachable connection design, allows branch pipe fittings to be installed and removed independently, simplifying the maintenance process while ensuring sealing and reducing the probability of leakage caused by loose connections.

[0011] In one embodiment of this utility model, a connecting groove is provided at the center of the mating column; the lower end of the branch pipe is the mating end, and the mating end is connected by inserting into the connecting groove.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: This solution completes the assembly through axial insertion linear motion, with a simple operation path, significantly reducing the complexity of installation.

[0013] In one embodiment of this utility model, the bottom of the connecting groove is provided with a mating part; the bottom end of the mating end is provided with a locking part; wherein the mating part and the locking part cooperate to lock the branch pipe fitting and the base assembly.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application effectively prevents the branch pipe fittings from shifting in the axial direction of the pipeline, avoiding misalignment of the sealing interface caused by displacement. The mechanical locking structure can maintain the connection state even when the threaded connection fails, improving the overall reliability of the connection.

[0015] In one embodiment of this utility model, the mating part includes two symmetrically arranged abutting bosses with a mating gap between them; the locking part includes two symmetrically arranged abutting buckles; wherein the mating gap is greater than or equal to the width of the abutting buckle in the horizontal direction, and when the abutting buckle and the abutting boss form a mating, the upper end of the abutting buckle and the lower end of the abutting boss abut against each other to restrict the branch pipe fitting from moving along the central axis of the connecting groove.

[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: This application effectively prevents axial displacement of branch pipe fittings after installation, ensuring that the connection interface is always in a tight fit. The mechanical limiting effect of the boss and the snap-fit ​​eliminates the wear of the sealing gasket caused by axial movement, and the symmetrical structural design avoids structural deformation caused by stress concentration on one side, thereby significantly improving connection stability and sealing durability.

[0017] In one embodiment of this utility model, the lower end face of the abutting boss is provided with a positioning groove; the upper end face of the abutting buckle is provided with a positioning protrusion that matches the positioning groove.

[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution forms a dual constraint mechanism through the geometric interlocking of the positioning groove and the positioning protrusion, which significantly improves the torsional resistance. At the same time, the resistance generated by the interlocking of the mechanical structure allows the user to clearly sense whether the abutment protrusion and the abutment buckle are properly engaged, thus avoiding improper installation.

[0019] In one embodiment of this utility model, the lower end face of the upper base is provided with a first convex ring group, which is composed of multiple first concentric convex rings with different radii spaced apart, and a first annular gap is formed between any two adjacent first concentric convex rings; the upper end face of the lower base is provided with a second convex ring group, which is composed of multiple second concentric convex rings with different radii spaced apart, and a second annular gap is formed between any two adjacent second concentric convex rings; wherein, the second concentric convex rings are correspondingly engaged with the first annular gaps, and the first concentric convex rings are correspondingly engaged with the second annular gaps, so that the first convex ring group and the second convex ring group mesh with each other.

[0020] Compared with existing technologies, the technical effects achieved by this solution are as follows: This solution uses multiple first concentric convex rings and multiple second concentric convex rings to form an interlocking structure, which provides a better waterproof sealing effect when the base assembly is clamped on the wall of the flexible pipe.

[0021] In one embodiment of this utility model, a sealing waterproof sleeve is disposed between the connecting groove and the mating end.

[0022] Compared with existing technologies, the technical effects achieved by this solution are as follows: By adding a sealing and waterproof sleeve, this solution superimposes an elastic sealing function on the basis of mechanical connection, which makes up for the defect that rigid structures cannot completely eliminate assembly gaps and improves the waterproof reliability of the connection.

[0023] On the other hand, this utility model also provides a water supply pipeline, including quick-install fittings as in any of the above examples.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the technical effects corresponding to any of the above examples, which will not be elaborated here.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0026] (1) This application integrates a toothed meshing structure at the threaded connection, which automatically locks when tightened, effectively preventing the base assembly from rotating and loosening, and maintaining a constant pipe clamping force;

[0027] (2) The branch pipe fitting adopts a connection method that combines axial insertion and snap locking, which simplifies the installation steps and avoids axial displacement through mechanical interlocking, thereby improving stability;

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] This utility model provides a quick-install pipe fitting for water supply pipelines, comprising: a base assembly 10, including an upper base 101 and a lower base 102, wherein a mating post is formed at the upper end of the lower base 102, and an external thread is provided on the outer side of the mating post; a mating groove is provided in the middle of the upper base 101, and an internal thread matching the external thread is provided on the inner side of the mating groove; an anti-reverse assembly, comprising a first tooth and a second tooth that match each other, wherein the first tooth is provided on the outer side of the mating post, and the second tooth is provided on the inner side of the mating groove; wherein, when the upper base 101 and the lower base 102 are fixedly clamped to the pipe wall 30 of the water supply pipeline by a threaded connection, the first tooth and the second tooth engage with each other to prevent the upper base 101 and the lower base 102 from rotating; and a branch pipe fitting 20, fixedly disposed on the base assembly 10.

[0042] Specifically, the water supply pipe is usually made of flexible material, and its pipe wall 30 has multiple openings.

[0043] Furthermore, the base assembly 10 refers to the main structure that clamps the pipe through the upper base 101 and the lower base 102. The base assembly 10 is set through the opening, and the cooperation of the external thread and the internal thread forms an axial clamping force, so that the base assembly 10 is clamped on the pipe wall near the opening.

[0044] Furthermore, the anti-retraction component refers to a mechanical structure that prevents rotation through tooth engagement, specifically achieved by alternating interlocking of oblique triangular protrusions and grooves. The first tooth refers to the anti-loosening structure located at the upper end of the external thread, specifically achieved by a ring-shaped array of wedge-shaped tooth blocks. The second tooth refers to the complementary structure located at the lower end of the internal thread, specifically achieved by tooth grooves that are mirror-symmetrical to the first tooth, with the groove depth matching the tooth block height.

[0045] Specifically, the upper base 101 and the lower base 102 generate axial pressure through threaded engagement, clamping the pipe wall 30 between them. When the threads are tightened to a preset torque, the toothed blocks on the outer side of the mating column and the toothed grooves on the inner side of the mating groove enter a meshing state. At this time, the contact pressure between the tooth surfaces creates additional friction, while the lateral constraint of the toothed block by the toothed groove sidewall creates a mechanical interlocking effect.

[0046] Optionally, the branch fitting 20 is fixed to the side of the base assembly 10 by welding or snap-fitting to form a stable diversion channel. When the pipeline is subjected to external vibration, the toothed meshing structure can prevent the threaded pair from rotating in the opposite direction and maintain the stability of the clamping force.

[0047] Optionally, branch fitting 20 can be a common tee or tee valve, elbow or elbow valve, or other straight-through type pipe or valve.

[0048] In one embodiment of the present invention, the first tooth portion includes a plurality of anti-retraction tooth protrusions 1021 evenly distributed along the outer side of the mating post, and the anti-retraction tooth protrusions 1021 are located at the upper end of the external thread; the second tooth portion includes a plurality of mating tooth protrusions 1011 evenly distributed along the inner side of the mating groove, and the mating tooth protrusions 1011 are located at the upper end of the internal thread.

[0049] Specifically, the anti-reverse tooth protrusion 1021 refers to the raised structure formed at the upper end of the external thread, which is implemented by a metal protrusion with a triangular cross-section, and the even distribution makes the circumferential direction form equal angle intervals. The mating tooth protrusion 1011 refers to the recessed structure opened at the upper end of the internal thread, and the groove depth can be set to be equal to the height of the anti-reverse tooth protrusion 1021.

[0050] Specifically, when the upper base 101 and the lower base 102 are tightened by threads, the engagement of the external and internal threads causes the anti-reverse tooth protrusion 1021 to automatically align with the mating tooth protrusion 1011. When the thread is screwed to the end, the anti-reverse tooth protrusion 1021 engages with the mating tooth protrusion 1011 to form a mechanical interlock, and the evenly distributed tooth protrusions and grooves form multiple contact points in the circumferential direction. Since the tooth protrusion is located at the top of the external thread and the groove is located at the end of the internal thread, the two form a horizontal limit when the thread is fully tightened. The torsional force generated by the pipe vibration is decomposed into axial pressure by the inclined contact surface of the tooth protrusion and the groove, thereby preventing the thread from rotating.

[0051] Preferably, the branch fitting 20 is detachably connected to the base assembly 10.

[0052] In one embodiment of this utility model, a connecting groove is provided at the center of the mating column; the lower end of the branch pipe 20 is the mating end 201, and the mating end 201 is connected by inserting into the connecting groove.

[0053] Specifically, the connecting groove refers to a channel structure that passes through the mating column along the axial direction of the base assembly 10, and its inner diameter forms a clearance fit or interference fit with the outer diameter of the mating end 201. This structure provides a guide channel for the axial insertion of the branch fitting 20, making the installation direction clear and eliminating the need for angle adjustment.

[0054] Furthermore, the mating end 201 refers to the connection part where the lower end of the branch fitting 20 matches the shape of the connecting groove. This design achieves rapid positioning through complementary shapes and enhances connection stability by utilizing the frictional force generated by axial insertion.

[0055] Specifically, when the branch fitting 20 needs to be installed, the mating end 201 is inserted vertically into the base assembly 10 along the axis of the connecting groove. The inner wall of the connecting groove forms a circumferential constraint on the mating end 201, preventing the branch fitting 20 from shifting radially. During insertion, the mating relationship between the mating end 201 and the connecting groove is self-aligned through precise dimensional control, ensuring the coaxiality of the connection.

[0056] In one embodiment of this utility model, the bottom of the connecting groove is provided with a mating part; the bottom end of the mating end 201 is provided with a locking part; wherein the mating part and the locking part cooperate to lock the branch pipe 20 with the base assembly 10.

[0057] Preferably, the mating part includes two symmetrically arranged abutment bosses 1022, with a mating gap between the abutment bosses 1022; the locking part includes two symmetrically arranged abutment buckles 202; wherein, the mating gap is greater than or equal to the width of the abutment buckle 202 in the horizontal direction, and when the abutment buckle 202 and the abutment boss 1022 are mated, the upper end of the abutment buckle 202 and the lower end of the abutment boss 1022 abut against each other to restrict the branch pipe fitting 20 from moving along the central axis of the connecting groove.

[0058] Specifically, the mating part refers to the symmetrical protruding structure located at the bottom of the connecting groove, which can be implemented by two opposing abutment bosses 1022, with a gap between the abutment bosses 1022 to allow the locking part to pass through. This structure restricts the axial movement of the branch pipe fitting 20 by the vertical abutment surfaces of the bosses and the locking part.

[0059] Furthermore, the locking part refers to the symmetrical snap-fit ​​structure at the bottom of the branch fitting 20, which can be implemented by using two snap-fits 202 that are spatially complementary to the abutment boss 1022. When inserted into the connecting groove, this structure passes through the gap between the bosses, and then, by rotating at a certain angle, the upper end face of the snap-fit ​​forms a surface contact limit with the lower end face of the boss.

[0060] Specifically, when the mating end 201 of the branch fitting 20 is inserted into the connecting groove, the abutment buckle 202 first passes through the mating gap between the abutment bosses 1022. After being inserted into place, it is rotated at a certain angle, and the upper end face of the buckle and the lower end face of the boss form a vertical contact plane, thereby generating a mechanical blocking effect.

[0061] Optionally, the width of the mating gap is set to be slightly larger than the horizontal width of the snap fastener to ensure that the snap fastener can pass through the gap smoothly during assembly.

[0062] In one embodiment of this utility model, the lower end face of the abutment boss 1022 is provided with a positioning groove 1023; the upper end face of the abutment buckle 202 is provided with a positioning protrusion 203 that matches the positioning groove 1023.

[0063] Specifically, the positioning groove 1023 refers to a recessed structure provided on the bottom surface of the abutment boss 1022, used to form a fitting relationship with the positioning protrusion 203. The positioning protrusion 203 refers to a protruding structure provided on the top of the abutment buckle 202, which restricts the relative rotation between the branch pipe fitting 20 and the base assembly 10 through geometric fit.

[0064] Specifically, when the branch fitting 20 is inserted into the base assembly 10 and rotated at a certain angle, the positioning protrusion 203 of the abutment buckle 202 is embedded in the positioning groove 1023 of the abutment boss 1022. The mechanical interlocking of the concave and convex structure causes the branch fitting 20 to generate resistance when rotating around the central axis of the connecting groove, thereby limiting axial displacement.

[0065] In one embodiment of this utility model, the lower end face of the upper base 101 is provided with a first convex ring group 1012, which is composed of multiple first concentric convex rings with different radii spaced apart, and a first annular gap is formed between any two adjacent first concentric convex rings; the upper end face of the lower base 102 is provided with a second convex ring group 1025, which is composed of multiple second concentric convex rings with different radii spaced apart, and a second annular gap is formed between any two adjacent second concentric convex rings; wherein, the second concentric convex rings are correspondingly engaged with the first annular gaps, and the first concentric convex rings are correspondingly engaged with the second annular gaps, so that the first convex ring group 1012 and the second convex ring group 1025 mesh with each other.

[0066] Specifically, this solution is applicable to flexible pipe fittings. The first concentric convex ring is circular in shape, and multiple first concentric convex rings spread outward from the center of the lower end face of the upper base 101 to form a concentric circle structure. Similarly, the second concentric convex ring is circular in shape, and multiple second concentric convex rings spread outward from the center of the upper end face of the lower base 102 to form a concentric circle structure. The positions of the first and second concentric convex rings are staggered and correspond to each other. When the upper base 101 and the lower base 102 are fixedly engaged with each other, the first concentric rings and the second annular gaps are engaged, and the second concentric rings and the first annular gaps are engaged, so that the base assembly 10 is firmly engaged with the pipe wall of the flexible pipe fitting, thereby improving the overall sealing and waterproofing effect.

[0067] Optionally, the bottom of the upper base 101 is provided with a plurality of evenly distributed trapezoidal grooves 1013. When the base assembly 10 is clamped on the pipe wall of the flexible pipe, the protrusion between adjacent trapezoidal grooves 1013 presses against the surface of the pipe wall, and the inclination angle of the trapezoidal side of one side of the trapezoidal groove 1013 along the rotation locking direction is greater than that of the trapezoidal side of the other side, so as to achieve the demolding effect.

[0068] Optionally, the outer side of the upper base 101 is provided with evenly distributed ribs 1014, which extend in the vertical direction and can provide a force point when tightening.

[0069] Optionally, the bottom of the lower base 102 is provided with two relatively parallel reference planes 1024, which can serve as a reference in the horizontal direction, making it easy to set the water supply direction of the branch pipe fitting 20 to be perpendicular to the water supply direction of the water supply pipe on the horizontal plane during installation.

[0070] In one embodiment of this utility model, a sealing waterproof sleeve 103 is disposed between the connecting groove and the mating end 201.

[0071] Specifically, the sealing and waterproof sleeve 103 refers to a ring-shaped fitting made of elastic sealing material, which can be rubber or silicone. Its inner diameter matches the outer diameter of the mating end 201, and its outer diameter matches the inner diameter of the connecting groove. During assembly, this fitting is compressed and filled in the gap between the outer wall of the mating end 201 and the inner wall of the connecting groove, eliminating gaps caused by assembly tolerances through elastic deformation.

[0072] The area between the connecting groove and the mating end 201 refers to the annular assembly area formed when the branch pipe fitting 20 is inserted into the base assembly 10. Specifically, axial positioning is achieved by inserting the mating end 201 of the branch pipe fitting 20 into the connecting groove of the base assembly 10. The sealing waterproof sleeve 103 forms a radial sealing interface in this area, covering the contact area between the outer surface of the mating end 201 and the inner surface of the connecting groove.

[0073] Specifically, during the assembly of the branch pipe fitting 20 and the base assembly 10, the sealing waterproof sleeve 103 is compressed and wrapped around the outer wall of the mating end 201, and its elastic deformation makes the sleeve fit tightly against the inner wall of the connecting groove. When the water pressure inside the pipe acts on the sealing waterproof sleeve 103, the sleeve expands further under pressure, enhancing the filling effect on the assembly gap. Thus, the sealing waterproof sleeve 103 forms a continuous circumferential sealing band, blocking the path of water flow to seep outward along the gap between the mating end 201 and the connecting groove.

[0074] In some specific embodiments, the axial length of the sealing waterproof sleeve 103 can cover the depth range of the mating end 201 inserted into the communicating groove, for example, extending from the top of the mating end 201 to the locking part installation position. The cross-sectional shape of the sealing waterproof sleeve 103 can be rectangular or trapezoidal to accommodate assembly gaps of different sizes.

[0075] On the other hand, this utility model also provides a water supply pipeline, including quick-install fittings as described in any of the above examples. Correspondingly, in this embodiment, the technical effects corresponding to any of the above technical solutions can be achieved, which will not be elaborated here.
