As shown in fig. 1, in one embodiment, there is provided a connecting pipe 10, including a pipe body 11 and a retaining member 13, as shown in fig. 4, the pipe body 11 is provided with a mounting groove 112 for mounting a pipe 20 to be connected, a bottom wall of the mounting groove 112 is provided with a channel 113 through which water flows, the pipe body 11 is provided with a detection hole 111 penetrating through a pipe wall of the pipe body 11, the detection hole 111 is located at a bottom end of the mounting groove 112, the retaining member 13 is mounted on the pipe body 11, and the retaining member 13 can be pressed on the pipe 20 to be connected.
The connecting pipe fitting 10 provided in the above-mentioned scheme is used to observe and judge whether the insertion depth of the pipe material 20 to be connected meets the installation requirement through the detection hole 111, and does not need to use complex manufacturing process or special materials, so that the cost is reduced on the whole, and the market competitiveness is improved. Specifically, on the one hand, whether the pipe 20 to be connected is installed in place can be judged by directly observing whether the pipe 20 to be connected passes through the position of the detection hole 111, and on the other hand, when an auxiliary member such as a guide member or a sealing member is further arranged at the front end of the pipe 20 to be connected, the auxiliary member moves synchronously with the pipe 20 to be connected, and whether the auxiliary member passes through or is positioned at the position of the detection hole 111 is observed through the detection hole 111, so that whether the pipe 20 to be connected is installed in place is judged. When the pipe 20 to be connected is installed in place, the retaining member 13 is pressed against the pipe 20 to be connected, so as to prevent the pipe 20 to be connected from exiting from the pipe body 11, thereby realizing the installation of the pipe 20 to be connected.
For example, as shown in fig. 1 and fig. 2, in one embodiment, a sliding ring 12 is further provided in the connecting pipe 20, as shown in fig. 5, an annular first sealing groove 121 is provided on the outer wall of the sliding ring 12, a first sealing ring 14 is installed in the first sealing groove 121, the sliding ring 12 is slidably disposed in the mounting groove 112, in the initial state, the sliding ring 12 is located on a side of the detecting hole 111 near the opening of the pipe body 11, the sliding ring 12 can be pushed by the pipe 20 to be connected in a direction near the bottom end of the mounting groove 112, when the insertion depth of the pipe 20 to be connected is enough, the first sealing ring 14 is located on a side of the detecting hole 111 far from the opening of the pipe body 11, and the first sealing ring 14 abuts against the side wall of the mounting groove 112.
In the initial state, the sliding ring 12 is positioned at the side of the detection hole 111 close to the opening of the pipe body 11. When the pipe 20 to be connected needs to be installed, the pipe 20 to be connected is inserted into the pipe body 11, and as the pipe 20 to be connected is gradually inserted, the pipe 20 to be connected pushes the sliding ring 12 towards the direction close to the bottom end of the installation groove 112, and when the insertion depth of the pipe 20 to be connected is enough, as shown in fig. 3, the sliding ring 12 covers the position where the detection hole 111 is located. Whether the sliding ring 12 is pushed by the pipe 20 to be connected is observed through the detection hole 111, so that whether the insertion depth of the pipe 20 to be connected meets the installation requirement is judged. Moreover, the first seal ring 14 also plays a role in preventing water leakage. Specifically, based on the connection pipe 10 having an external sealing structure, the pipe 20 to be connected needs to be inserted into the connection pipe 10 during use, and in order to observe whether the pipe 20 to be connected is in place, the problem of leakage caused by the provision of the detection hole 111 exists. I.e. if the pipe 20 to be connected is not in place, the water will leak out from the detection port after water is introduced. Even if the pipe 20 to be connected is installed in place, based on the characteristics of the materials of the pipe 20 to be connected and the connecting pipe 10, gaps exist between the pipe 20 to be connected and the connecting pipe 10, and water flows from the gaps to the detection holes 111 during water supply, so that leakage occurs. Therefore, by providing the first sealing groove 121 on the sliding ring 12, the first sealing ring 14 is provided in the first sealing groove 121, and when the pipe 20 to be connected is installed in place, the first sealing ring 14 is located at the side of the detection hole 111 away from the opening of the pipe body 11 and abuts against the side wall of the installation groove 112, so that water is prevented from flowing out from the gap between the end of the sliding ring 12 away from the pipe body 11 and the pipe body 11, and water is prevented from flowing out from the detection hole 111. Therefore, the purpose of judging whether the pipe 20 to be connected is installed in place can be achieved by observing whether water leaks or not. When the pipe 20 to be connected is installed in place, the retaining member 13 is pressed on the pipe 20 to be connected, so that the pipe 20 to be connected is prevented from exiting from the pipe body 11, and further, the pipe 20 to be connected and the sliding ring 12 are always kept in a communicating state, and the installation reliability of the pipe 20 to be connected in the connecting pipe 10 is also ensured.
And, when the pipe 20 to be connected is directly observed through the detection hole 111 to pass through the position of the detection hole 111, thereby judging whether the insertion depth of the pipe 20 to be connected meets the installation requirement. As described above, although the detection hole 111 can visually observe whether the insertion depth of the pipe 20 to be connected meets the requirement, a gap exists between the pipe 20 to be connected and the pipe 10 to be connected, so that there is a problem of leakage. At this time, an annular mounting groove for mounting the sealing ring can be formed in the inner wall of the mounting groove 112, and the annular mounting groove is located on one side of the detection hole 111 away from the opening of the pipe fitting body 11, when the pipe fitting 20 to be connected is mounted in place, the sealing ring abuts against the outer wall of the pipe fitting 20 to be connected, so that a sealing effect is achieved, and water leakage is prevented. So that it can be judged whether the pipe 20 to be connected is installed in place by observing whether there is water leakage in the water-passing state.
In addition, in order to further facilitate the observation of whether the sliding ring 12 reaches the position where the detection hole 111 is located, the sliding ring 12 may be made of a material having a color that is different from that of the pipe fitting body 11, or a bright material may be coated on the outer surface of the sliding ring 12. The first sealing ring 14 needs to have a sealing effect when passing through the position of the detection hole 111 during use, so that the first sealing ring 14 is pressed against the side wall of the mounting groove 112 when passing through the position of the detection hole 111. In order to prevent the first seal ring 14 from being scratched, it is necessary to provide a burr-free portion at a position where the detection hole 111 and the side wall of the mounting groove 112 are located in a boundary during the design process.
Further, as shown in fig. 1 and 5, in one embodiment, the outer wall of the sliding ring 12 is provided with an annular second sealing groove 122, the second sealing groove 122 is located at one side of the first sealing groove 121 close to the opening of the pipe body 11, a second sealing ring 15 is installed in the second sealing groove 122, a distance between the first sealing ring 14 and the second sealing ring 15 is greater than a diameter of the detection hole 111, when the insertion depth of the pipe 20 to be connected is enough, the second sealing ring 15 is located at one side of the detection hole 111 close to the opening of the pipe body 11, and the second sealing ring 15 abuts against a side wall of the installation groove 112.
By further arranging the second sealing groove 122 on the sliding ring 12, when the pipe 20 to be connected is installed in place, the first sealing ring 14 and the second sealing ring 15 are respectively abutted against two sides of the detection hole 111, so that the sealing performance of the connecting pipe 10 is improved under the condition that whether the pipe 20 to be connected is installed in place or not can be observed. Specifically, when the pipe 20 to be connected is installed in place, both sides of the detection hole 111 are in a sealed state based on the presence of the first sealing ring 14 and the second sealing ring 15, so that no water leakage occurs, and whether the pipe 20 to be connected is installed in place can be determined by observing whether the detection hole 111 leaks in a water-through state.
Further, in the above scheme, the pipe 20 to be connected is pushed to move the sliding ring 12 in the mounting groove 112, and the pipe passes through the detection hole 111 to determine whether the pipe is in place. Specifically, the sliding ring 12 may be a cylindrical hole having the same front-rear diameter at the position where the mounting groove 112 slides. Of course, the diameters of the different sections of the mounting groove 112 may be set differently to enhance the sliding and sealing effects of the sliding ring 12 in the pipe member body 11.
For example, as shown in fig. 4, in one embodiment, the mounting groove 112 includes a first groove 1121 and a second groove 1122, the first groove 1121 is a portion of the mounting groove 112 near the bottom end, the second groove 1122 is located at a side of the first groove 1121 near the opening of the pipe body 11, and the diameter of the second groove 1122 is larger than the diameter of the first groove 1121. By setting the diameter of the second groove 1122 to be larger than the diameter of the first groove 1121, the sliding process of the sliding ring 12 is ensured, and the sealing performance of the first sealing ring 14 is also ensured when the pipe 20 to be connected is installed in place. Specifically, based on the diameter of the second groove 1122 being larger than the diameter of the first groove 1121, the sliding ring 12 is easier to be pushed by the pipe 20 to be connected in the initial state, and when the sliding ring 12 reaches the position of the detection hole 111, the first groove 1121 with smaller aperture can ensure the sealing performance of the first seal ring 14 and the second seal ring 15.
Further, as shown in fig. 4, in one embodiment, the portion of the mounting groove 112 between the first-stage groove 1121 and the second-stage groove 1122 is a guide portion 1123, and a side wall of the guide portion 1123 is a tapered guide surface. Further guiding the sliding movement of the sliding ring 12 during use.
Further, as shown in fig. 3, in one embodiment, the length of the first slot 1121 along the axial direction of the pipe body 11 is a first length, and the length of the sliding ring 12 along the axial direction of the pipe body 11 is a second length, and the first length is equal to the second length. In this way, the first sealing ring 14 and the second sealing ring 15 are ensured to reliably realize sealing, and the sliding ring 12 is conveniently pushed into the first section groove 1121 by the pipe 20 to be connected. Specifically, if the first length is greater than the second length, if the outer diameter of the pipe 20 to be connected is greater than the diameter of the first section slot 1121, when the pipe 20 to be connected pushes the sliding ring 12, the pipe 20 to be connected cannot enter the first section slot 1121, and it cannot be well ensured that the sliding ring 12 is pushed in place. If the first length is smaller than the second length, it cannot be reliably ensured that the sealing process can be reliably implemented by both the first sealing ring 14 and the second sealing ring 15. Therefore, by setting the first length to be identical to the second length, it is also convenient for the pipe 20 to be connected to push the sliding ring 12 into the first-stage groove 1121 while ensuring that the first seal ring 14 and the second seal ring 15 can reliably achieve sealing.
Further, as shown in fig. 4, in one embodiment, the mounting groove 112 further includes a third groove 1124, the third groove 1124 is located on a side of the second groove 1122 close to the opening of the pipe body 11, the diameter of the third groove 1124 is greater than that of the second groove 1122, as shown in fig. 2, a third sealing ring 17 is installed in the third groove 1124, the inner diameter of the third sealing ring 17 is smaller than the outer diameter of the pipe 20 to be connected, and the inner diameter of the third sealing ring 17 is smaller than the outer diameter of the first sealing ring 14.
By arranging the third sealing ring 17, the pipe 20 to be connected and the pipe body 11 are sealed, and the inner diameter of the third sealing ring 17 is smaller than the outer diameter of the first sealing ring 14, so that when the sliding ring 12 is positioned in the second section groove 1122, the third sealing ring 17 also protects the sliding ring 12, and the sliding ring 12 is prevented from falling from the pipe body 11.
Furthermore, as shown in fig. 2 and 3, the presence of the second seal ring 15 and the third seal ring 17 can effectively prevent leakage of water flowing out from between the pipe 20 to be connected and the sliding ring 12. Specifically, the second seal ring 15 prevents water from leaking from the detection hole 111, and the third seal ring 17 prevents water from leaking from a gap between the pipe 20 to be connected and the pipe body 11, thereby realizing the sealing process of the connecting pipe 10.
Further, in the foregoing solution, by the arrangement of the sliding ring 12, only by pushing the sliding ring 12 by the pipe 20 to be connected, the sliding ring 12 will move into the first section slot 1121, as shown in fig. 1 to 3, in one embodiment, the connecting pipe 10 further includes a guide sleeve 16 for being inserted into the pipe 20 to be connected, as shown in fig. 6, an end portion of the guide sleeve 16 is provided with a sealing flange 161, as shown in fig. 10, one side of the sealing flange 161 can abut against an end face of the pipe 20 to be connected, and the other side of the sealing flange 161 can abut against an end face of the sliding ring 12 close to the opening of the pipe body 11, and the length of the guide sleeve 16 is longer than the distance between the stopper 13 and the first section slot 1121. And on the basis of the material characteristics of the pipe 20 to be connected, the guiding sleeve 16 plays a supporting role on the pipe 20 to be connected, and on the other hand, the length of the guiding sleeve 16 is set to be larger than the distance between the retaining member 13 and the first section slot 1121, so that the part, abutted by the retaining member 13, of the pipe 20 to be connected can be supported by the guiding sleeve 16. Further, the end of the guiding sleeve 16 away from the sealing flange 161 is provided with a guiding cone for guiding the pipe 20 to be connected, so as to facilitate the installation of the pipe.
And because the material of the pipe 20 to be connected is softer, the length of the guide sleeve 16 is set to be greater than the distance between the retaining member 13 and the first section slot 1121, so that when the pipe 20 to be connected is installed in place, the position where the third sealing ring 17 is abutted against the pipe 20 to be connected and the position where the retaining member 13 is abutted against the pipe 20 to be connected are supported by the guide sleeve 16, and the guide sleeve 16 is made of a material with higher strength, thereby improving the sealing performance of the third sealing ring 17 and the retaining reliability of the retaining member 13 on the pipe 20 to be connected. Specifically, the guide sleeve 16 may be injection molded from a plastic such as PPSU, high temperature nylon, or the like, which has high wear resistance and strength.
Further, as shown in fig. 4, in one embodiment, the diameter of the channel 113 is smaller than the diameter of the mounting groove 112, and the end surface of the sliding ring 12 away from the pipe member body 11 can abut against the bottom wall of the mounting groove 112. When the pipe 20 to be connected is installed in place, the sliding ring 12 is located at the position where the detection hole 111 is located, i.e. in the first section slot 1121, and when the sliding ring 12 is pushed into the first section slot 1121 by the pipe 20 to be connected, the sliding ring can be limited by the bottom wall of the mounting slot 112 in an abutting manner based on the fact that the diameter of the channel 113 is smaller than the diameter of the mounting slot 112. Specifically, when the pipe 20 to be connected is gradually inserted into the pipe body 11, the pipe 20 to be connected cannot be inserted inwards any more, so that the situation that the insertion depth of the pipe 20 to be connected is too large is avoided.
Further, when the first length and the second length are equal as described above, the sliding ring 12 abuts against the bottom wall of the mounting groove 112, it is verified that the sliding ring 12 is completely located in the first-stage groove 1121, that is, it is verified that the pipe 20 to be connected is mounted in place.
Further, in one embodiment, as shown in fig. 1 to 4, the number of the detecting holes 111 is plural, and a plurality of detecting holes 111 are arranged on the pipe body 11 in a spaced-apart ring. By providing a plurality of detection holes 111, the installation process can be more conveniently observed.
In the above-mentioned solution, the retaining member 13 may be a fastening structure disposed at an opening of the pipe body 11, and when the depth of insertion of the pipe 20 to be connected is sufficient, the pipe 20 to be connected is fixedly connected with the pipe 20 to be connected, so as to limit the pipe 20 to be connected in the pipe body 11. Or the retaining member 13 is a locking ring sleeved at the end part of the pipe fitting body 11, the locking ring can be contracted and tensioned, the end part of the pipe fitting body 11 can be compressed and deformed by the locking ring, when the pipe fitting 20 to be connected is installed in place, the locking ring is tensioned, so that the locking ring extrudes and deforms the end part of the pipe fitting body 11, and finally the pipe fitting body 11 to be connected is pressed on the pipe fitting 20 to be connected, and the purpose of limiting the pipe fitting 20 to be connected to be withdrawn is achieved.
Or specifically, as shown in fig. 1 and fig. 8 to fig. 10, in an embodiment, the connecting pipe 10 further includes a pressing ring 18 and a pressing sleeve 19, the retaining member 13 is an internal tooth locking ring, as shown in fig. 4, a closing groove is dug on an end surface of the pipe body 11, a portion of a pipe wall of the pipe body 11 corresponding to the closing groove is a closing section 114, the mounting groove 112 further includes a fourth section groove 1125 and a fifth section groove 1126, the closing groove, the fifth section groove 1126 and the fourth section groove 1125 are sequentially and adjacently arranged, and the internal tooth locking ring is installed in the fourth section groove 1125, the pressing ring 18 is installed in the fifth section groove 1126, the closing section 114 can be bent inwards and pressed on an end surface of the pressing ring 18, the other end surface of the pressing ring 18 can be pressed on the locking ring, the pressing sleeve 19 is inserted in the pressing ring 18, the pressing ring 19 is close to the pressing ring 18, and is far away from the pressing ring 18, and the pressing ring is far from the inner tooth locking ring 18, and the pressing ring is far from the pressing ring 18.
In use, as shown in fig. 7, the internal tooth locking ring is placed in the fourth segment slot 1125, then the pressing sleeve 19 is inserted into the pressing ring 18, and finally the pressing ring 18 is placed in the fifth segment slot 1126. Then, as shown in fig. 8, the closing-in section 114 is bent inward to be pressed against the end face of the pressing ring 18, thereby achieving the function of limiting and fixing the internal tooth locking ring, the pressing sleeve 19 and the pressing ring 18. Specifically, the bending process of the closing-in section 114 may be implemented by using a closing-in mold to press the closing-in section 114 of the pipe body 11, or by using a rotating process to press the closing-in section 114. To facilitate the bending process of the closing-in section 114, the pipe body 11 may be made of a metallic material with better toughness.
After the internal tooth locking ring, the press sleeve 19 and the press ring 18 are mounted in place, as shown in fig. 9, the pipe material to be connected 20 is sleeved on the guide sleeve 16, and then the pipe material to be connected 20, into which the guide sleeve 16 is inserted, is inserted into the mounting groove 112. And when the pipe 20 to be connected is inserted into the mounting groove 112, the internal teeth of the internal tooth locking ring are deformed by the pipe 20 to be connected, and are inclined in a direction away from the opening of the pipe body 11, so that the internal teeth of the internal tooth locking ring are pressed against the pipe 20 to be connected. At this time, the pipe 20 to be connected can be inserted into the pipe body 11 only and cannot be withdrawn in the opposite direction. As shown in fig. 10, as the insertion depth of the pipe 20 to be connected increases, the pipe 20 to be connected abuts against the sliding ring 12, and the sliding ring 12 is gradually pushed into the first section slot 1121, so as to implement the installation process of the pipe 20 to be connected.
If the pipe 20 to be connected, which is installed in the pipe fitting body 11, needs to be taken out, the pressing sleeve 19 is pushed into the pipe fitting body 11, so that the pressing end of the pressing sleeve 19 gradually expands the internal teeth of the internal tooth locking ring, and the pipe can be removed from the pipe fitting body 11 after the pipe with connection is separated from the locking of the internal tooth locking ring. Specifically, a semicircular pressing piece slightly larger than the outer diameter of the pipe can be sleeved on the pipe, and then the pressing sleeve 19 is pressed by the pressing piece along the axial direction of the pipe, so that the internal teeth are spread by the pressing end of the pressing sleeve 19, and the pipe 20 to be connected is taken out. When the pipe 20 to be connected is taken out, the spread internal teeth can be hooked out to a direction approaching the opening of the pipe body by a tool, so that the internal tooth locking ring is restored to the original state. Moreover, in order to facilitate the pressing end to press the internal teeth of the internal tooth locking ring, the pressing end of the pressing sleeve 19 can be set to be of a conical structure, adapt to the shape of the internal teeth, and facilitate the pressing end to open the internal tooth locking ring. This also enables recycling of the pipe 20 to be connected and the connecting pipe 10, thereby reducing costs.
Further, as shown in fig. 4, the mounting groove 112 further includes a sixth segment groove 1127, the sixth segment groove 1127 is disposed adjacent to the fourth segment groove 1125, the sixth segment groove 1127 is located at a side of the fourth segment groove 1125 away from the opening of the pipe body 11, a circular truncated cone-shaped hole is surrounded by a side wall of the sixth segment groove 1127, an aperture of a circular truncated cone-shaped hole near one end of the fourth segment groove 1125 is larger than an aperture of the other end of the circular truncated cone-shaped hole, and an inclination of a side wall of the sixth segment groove 1127 is adapted to a maximum inclination of internal teeth of the internal tooth locking ring. By adapting the inclination of the side wall of the sixth groove 1127 to the maximum inclination of the internal teeth of the internal tooth locking ring, the occurrence of damage caused by the transition of the internal tooth deformation of the internal tooth locking ring due to the excessive outer diameter of the pipe 20 to be connected is avoided.
Specifically, the connecting pipe 10 in each of the above embodiments may be a straight pipe, a bent pipe, a three-way pipe or other pipe with multiple ports, and it is within the scope of the above scheme as long as the corresponding structure of the connecting pipe 10 corresponding to any of the above embodiments is provided in the included pipe.
