Abstract
Description
Technical Field
[0001] The utility model relates to a buckle ring structure, in particular to a pipe joint with the buckle ring structure. Background Art
[0002] See also Figure 1 As shown, the conventional buckle structure is constituted as an annular buckle 1 extending in the circumferential direction, and the buckle 1 has two free ends 10. There is a gap 12 between the two free ends 10, whereby the conventional buckle 1 is designed to be set at a corresponding position on the inner side or outer side of a corresponding tube body (not shown) through compression or expansion of the two free ends 10. Wherein, when the conventional buckle 1 is compressed, the gap 12 is narrowed by applying an external force of compression to the two free ends 10, so that the buckle 1 can be set into a corresponding position (for example, a slot hole) inside the tube body. At this time, the buckle 1 will be at the corresponding position of the tube body, so that the conventional annular buckle 1 is limited.
[0003] With the above structure, the conventional retaining ring 1 is used to axially fix the components contained in various pipe joints (for example, a spring disposed in a pipe body, etc.). However, the conventional retaining ring 1 is a flat and thin elastic member. In addition to being easy to cause the retaining ring 1 to rotate in the pipe joint and affect the stability of the installation, due to the influence of tolerances or specifications, the shape of the retaining ring 1 will affect the passage of fluid inside the pipe body, thereby causing the problem of unsmooth flow path. In addition, when the conventional retaining ring 1 is used to axially fix the components contained in the pipe joint, the inconsistent inner diameter tolerance of the retaining ring 1 may be unfavorable for the bearing of the spring, thereby affecting the axial fixing effect of the spring. As a result, it is necessary to further set an additional bearing element (such as a gasket) between the above-mentioned component and the retaining ring 1, which increases the number of components of the pipe joint.
[0004] Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the inventor of this case and related manufacturers engaged in this industry are eager to study and improve. Utility Model Content

DETAILED DESCRIPTION
[0021] The above-mentioned purpose and the structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings.
[0022] See also Figure 2 It is a three-dimensional exploded view of the pipe joint with a buckle ring structure of the utility model; Figure 3 It is a three-dimensional cross-sectional view of the pipe joint with a buckle structure of the utility model; Figure 4 It is a three-dimensional schematic diagram of a buckle ring of a pipe joint with a buckle ring structure according to the utility model.
[0023] like Figure 2 and Figure 3 As shown, the utility model provides a pipe joint with a buckle structure, comprising a pipe body 2, a movable valve head 3, a buckle 4 and a return spring 5. The two ends of the pipe body 2 are respectively provided with an opening 21 and a pipe interface 22, and a pipe passage 23 is provided through the pipe body 2. The pipe passage 23 is located between the opening 21 and the pipe interface 22 and is connected to each other, so that a fluid (such as water) can flow through the opening 21 and the pipe interface 22 in the pipe passage 23. In one embodiment, a conduit (not shown) can be sleeved with the pipe joint of the utility model from the rear end of the pipe body 2, and after the front end of the pipe body 2 is connected, the fluid from the conduit flows through the pipe interface 22 through the pipe passage 23 toward the opening 21. In addition, an annular groove 231 is provided circumferentially on the inner side of the pipe body 2 near the pipe interface 22.
[0024] like Figure 3 As shown, the movable valve head 3 is movably arranged in the tube channel 23 and seals the opening 21. In one embodiment, the movable valve head 3 is located in the tube channel 23 corresponding to the inner side of the front end of the tube body 2, and the movable valve head 3 and the tube body 2 are coaxially arranged, so that the outer periphery of the movable valve head 3 cooperates with the inner side of the tube channel 23 to seal the opening 21 and prevent the fluid from passing through. A water stop ring 31 is provided around the front end of the movable valve head 3 to enhance the sealing effect. When the front end of the movable valve head 3 is pushed by an external force, it can move toward the rear end of the tube body 2 to open the opening 21 and then conduct the tube channel 23.
[0025] The return spring 5 is disposed in the pipe passage 23 and is located between the movable valve head 3 and the buckle 4. In one embodiment, the two ends of the return spring 5 abut against the front end of the buckle 4 and the rear end of the movable valve head 3, respectively. Therefore, when the front end of the movable valve head 3 is subjected to an external force and moves toward the rear end of the pipe body 2, the return spring 5 will also be compressed along with the movement of the movable valve head 3. When the external force on the movable valve head 3 disappears, the compressed return spring 5 will release elastic potential energy, pushing the movable valve head 3 to move back to the front end of the pipe body 2 to seal the opening 21 again. In addition, the other end of the return spring 5 abuts against the buckle 4, and when the return spring 5 is compressed, it bears against the buckle 4, and transmits the force to the buckle 4.
[0026] The buckle ring 4 is disposed in the pipe passage 23 and adjacent to the pipe interface 22. Figure 3 and Figure 4 As shown, in one embodiment, the front end of the buckle 4 also has a bearing surface 44 facing the return spring 5. For example, the bearing surface 44 at the front end can be an annular plane between the outer diameter and the inner diameter of the buckle 4, and is perpendicular to the axial direction, and is used to be supported by the return spring 5. In the utility model, the return spring 5 directly bears against the bearing surface 44 of the buckle 4, thereby limiting its position and preventing axial movement from leaving the pipe channel 23.
[0027] The aforementioned buckle ring 4 is made of an elastic material, such as metal or non-metallic polymer, and is arranged coaxially with the tube body 2 in an annular shape. It has an annular portion 41 extending in the circumferential direction, and the annular portion 41 extends in the axial direction by an axial length 411, and has two radial free ends 412 and a contact surface 413 corresponding to the inner side of the tube body 2. A flange 4131 is convexly provided on the contact surface 413 in the circumferential direction, and the flange 4131 cooperates with the annular groove 231. For example, the flange 4131 is formed by the outer diameter step difference on the contact surface 413 of the annular portion 41, and the step difference formed can correspond to the annular groove 231. An elastic compression gap 42 is provided between the two radial free ends 412. When the buckle ring 4 is compressed by external force, the two radial free ends 412 will approach each other to narrow the elastic compression gap 42, so that the flange 4131 of the buckle ring 4 can enter the pipe interface 22 at the rear end of the tube body 2. In addition, the outer diameter of the buckle ring 4 is larger than the inner diameter of the rear end of the tube body 2. Therefore, after the buckle ring 4 enters the tube body 2 and the external force compressing the buckle ring 4 disappears, the buckle ring 4 will generate radial tension corresponding to the inner side of the tube body 2 and be set in the tube channel 23. At this time, the flange 4131 is set in the annular groove 231 to form a concave-convex fit. Therefore, when the return spring 5 is supported, the external force from the return spring 5 on the buckle ring 4 will be stopped by the flange 4131 against the annular groove 231 in the axial direction, thereby achieving the effect of axial fixing. In addition, by extending the axial length 411 to form the contact surface 413 , the contact area between the buckle ring 4 and the inner side of the tube body 2 is increased, thereby preventing the buckle ring 4 from rotating inside the tube body 2 , thereby achieving the effect of stabilizing the buckle ring 4 .
[0028] In addition, a through hole 43 is formed on the inner side of the buckle 4 and is located radially inside the pipe interface 22. Therefore, the fluid passing through the pipe interface 22 flows toward the opening 21 through the through hole 43. For example, the fluid from the above-mentioned conduit enters the tube body 2 after passing through the through hole 43 of the buckle 4 from the pipe interface 22, and then passes through the tube channel 23 and flows out from the opening 21. Further, the inner side of the annular portion 41 of the buckle 4 has a straight section 414 adjacent to the bearing surface 44 and a transition section 415 extending from the straight section 414 to the rear end of the buckle 4, and the transition section 415 gradually expands radially toward the rear end of the buckle 4. In detail, the through hole 43 is tapered on the radial inner side of the pipe interface 22 to guide the flow direction of the fluid. Therefore, due to the structures of the straight section 414 and the transition section 415 , the utility model can further improve the smoothness of the flow path in the tube channel 23 , and will not cause the above-mentioned problem of unsmooth flow path due to the provision of the buckle 4 .
[0029] In addition, in some embodiments, the two radial free ends 412 of the annular portion 41 are respectively provided with a lug 45. The lug 45 is for the user to more conveniently install or replace the buckle 4. The lug 45 is located at the rear end of the buckle 4. When the lug 45 is applied with an external force to move closer to each other, the lug 45 will drive the radial free ends 412 to move closer to each other, thereby compressing the elastic compression gap 42, so as to complete the setting of the buckle 4 as described above. In addition, the inner side of the rear end of the tube body 2 is also provided with a receiving groove 24 that matches the lug 45, and the receiving groove 24 is connected to the pipe interface 22. Therefore, when the buckle 4 is installed into the tube body 2, the lug 45 will also enter the receiving groove 24 from the connection between the receiving groove 24 and the pipe interface 22.
[0030] In summary, the present invention not only avoids the problem that the inconsistent inner diameter tolerance of the conventional retaining ring is not conducive to the bearing of the spring and affects the axial fixing effect of the spring, but also avoids the problem of the conventional need to add additional bearing components, resulting in an increase in the number of pipe joint components.
[0031] The above description has been a detailed description of the utility model, and the above description is only a preferred embodiment of the utility model, which should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made based on the concept of the utility model should still fall within the scope of the patent coverage of the utility model.
