Description

Technical Field

[0001] The present application relates to the technical field of pipeline connection, and in particular to a reducing tee pipe connector. Background Art

[0002] At present, in the field of pipeline connection technology, especially when dealing with the connection of pipelines with different diameters, there are many types of pipe connectors on the market. These connectors are usually used to ensure the sealing and stability of the pipeline system, reduce the risk of leakage, and improve the working efficiency of the system.

[0003] Under the relevant technology, in order to meet the connection requirements of pipes with different diameters, the existing solutions mainly include the following methods: first, using a standard-sized tee pipe fitting and installing a reducer to achieve the connection of pipes with different diameters; second, directly designing and manufacturing a reducing tee pipe fitting so that it can directly connect pipes with different diameters; third, using a hose or flexible connector to transition pipes with different diameters. These methods have their own characteristics in practical applications, but they still have limitations in certain specific situations.

[0004] Regarding the above-mentioned related technologies, although the above methods can solve the connection problem of pipes of different diameters to a certain extent, there are still some obvious defects. For example, the method of using a standard-sized three-way pipe fitting with a reducer not only increases the number and complexity of the connectors, but may also reduce the sealing of the connection parts and increase the risk of leakage. Although the directly designed and manufactured reducing three-way pipe fittings can simplify the connection process, their complex design, high cost, and difficulty in installation limit their widespread application. Therefore, how to design a simple and reliable reducing three-way pipe fitting to meet the connection requirements of pipes of different diameters has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to provide a structure that is convenient for connecting and installing a reducing tee pipe fitting with connecting pipes of different diameters, the present application provides a reducing tee pipe fitting connector.

[0006] The present application provides a reducing tee pipe connector, which adopts the following technical solution: A reducing tee pipe connector, characterized in that it comprises a pipe body, a connecting pipe and a connecting assembly; One end of the pipe body is in communication with the end of the connecting pipe, and the pipe body and the connecting pipe are connected via the connecting assembly; The connecting assembly includes a first connecting sleeve, an elastic member and a first tightening member. The first connecting sleeve is sleeved on the pipe body. A plurality of first tightening members are spaced apart along the circumference of the pipe body. The first tightening member is slidably connected to the first connecting sleeve along the radial direction of the pipe body. The first tightening member is tightly pressed against the inner wall of the connecting pipe. A first sealing ring is sleeved on the end of the pipe body. One side of the first sealing ring is in contact with the outer wall of the connecting pipe.

[0007] By adopting the above technical solution, by setting the first connecting sleeve and the first fastening member, when connecting tubes of different diameters (the diameter of the connecting tube is larger than the diameter of the pipe opening of the pipe fitting body) are connected to the pipe fitting body, the first fastening member slides along the radial direction of the pipe opening of the pipe fitting body until it fits against the inner wall of the connecting tube, so that one side of the first fastening member is pressed against the inner wall of the connecting tube to achieve the connection between the connecting tube and the pipe fitting body. By setting the slidable first fastening member, the connection and installation between the pipe fitting body and the connecting tubes of different diameters can be achieved.

[0008] Optionally, a side of the first retaining member away from the first connecting sleeve is arc-shaped, and an arc-shaped opening faces a side close to the first connecting sleeve.

[0009] By adopting the above technical solution, in order to improve the stability of the installation and fixation of the connecting pipe and the pipe fitting body, the first clamping member is arc-shaped on the side away from the first connecting sleeve, and the arc-shaped first clamping member fits against the inner wall of the connecting pipe, thereby increasing the contact area between the connecting pipe and the pipe fitting body, and further improving the stability between the connecting pipe and the pipe fitting body.

[0010] Optionally, the connecting assembly further comprises an elastic member, one end of which is connected to the first connecting sleeve, and the other end of which is fixedly connected to the first clamping member, and the elastic member has a force driving the first clamping member to move away from the first connecting sleeve under recoverable deformation.

[0011] By adopting the above technical solution, in order to enable the first clamping member to adapt to connecting tubes of different diameters (the diameter of the connecting tube is larger than the diameter of the tube opening of the pipe fitting body), that is, to enable the first clamping member to slide along the radial direction of the first connecting sleeve, an elastic member is arranged, and under the action of the elastic member, the first clamping member can always be in contact with the inner wall of the connecting tube, so that the connecting tube and the pipe fitting body are fixed.

[0012] Optionally, a first fixing ring is sleeved on the end of the connecting pipe close to the pipe body, and a second fixing ring is fixedly sleeved on the end of the first connecting sleeve away from the first clamping piece, the outer diameter of the first connecting sleeve gradually decreases toward the side away from the second fixing ring, and an oblique groove is provided on the side of the first fixing ring close to the second fixing ring along the length direction of the connecting pipe, and the wall of the oblique groove is in contact with the outer wall of the first connecting sleeve.

[0013] By adopting the above technical solution, when the pipe fitting body is inserted into the connecting pipe, in order to further improve the stability of the connection between the connecting pipe and the pipe fitting body and reduce the impact on the pipe fitting body when the water flow is too large, causing the pipe fitting body to be separated from the connecting pipe, for this purpose, a first fixing ring and a second fixing ring are set, and when the pipe fitting body is inserted into the connecting pipe, the groove wall of the inclined groove contacts and fits with the side wall of the first connecting sleeve, and the end wall of the first fixing ring abuts against the end wall of the second fixing ring. During the abutment contact between the first fixing ring and the second fixing ring, the connecting pipe will be further compressed to improve the tightness between the connecting pipe and the first connecting sleeve, thereby improving the tightness of the connection between the connecting pipe and the pipe fitting body.

[0014] Optionally, the first connecting sleeve is provided with a first opening along its length direction.

[0015] By adopting the above technical solution, when the first fixing ring and the second fixing ring are in contact with each other, in order to further improve the firmness of the connection between the first connecting sleeve and the pipe fitting body, the first connecting sleeve is penetrated and opened along its own axial direction with a first opening. When the distance between the first fixing ring and the second fixing ring is smaller, the second fixing ring is squeezed toward the side of the connecting pipe, and the first connecting sleeve is squeezed toward the side of the pipe fitting body, and the width of the first opening is smaller, so that the connection between the connecting pipe and the first connecting sleeve, and between the first connecting sleeve and the pipe fitting body is tighter and firmer, thereby further improving the firmness of the connection between the connecting pipe and the pipe fitting body.

[0016] Optionally, the second fixing ring is provided with a second opening along its length direction, and the second opening is arranged corresponding to the first opening.

[0017] By adopting the above technical solution, when the connecting tube is pressed toward one side of the first connecting sleeve, in order to make the second fixing ring follow the first connecting sleeve to synchronously press the pipe body, a second opening is opened on the second fixing ring, and the second opening is connected to the first opening, that is, the first opening and the second opening are arranged correspondingly, so that when the connecting tube is pressed toward one side of the first connecting sleeve, the width of the second opening becomes smaller accordingly.

[0018] Optionally, a locking assembly is further included, which includes a locking piece and a limiting piece. The locking piece is rotatably connected to the first fixing ring. The locking piece is perpendicular to the axial direction of the first fixing ring along the rotation axis of the first fixing ring. The locking piece is fixedly connected to the first fixing ring, and the limiting piece is fixedly connected to the outer side wall of the second fixing ring. The locking piece is provided with a slot for accommodating the limiting piece.

[0019] By adopting the above technical solution, by setting up a locking assembly, the locking piece is rotated, and the locking piece is rotated toward the side close to the limiting piece along the axial direction perpendicular to the first fixing ring until the limiting piece is located in the slot, so as to realize the locking of the first fixing ring and the second fixing ring.

[0020] Optionally, the connecting assembly is connected to the first connecting sleeve via a third fixing ring, the third fixing ring is sleeved on the first connecting sleeve, and the elastic member is fixedly connected between the third fixing ring and the first connecting sleeve.

[0021] By adopting the above technical solution, in order to facilitate the disassembly or replacement of the first pressing member, the connecting assembly is connected to the first connecting sleeve through the third fixing ring, and the first pressing member can be replaced or disassembled by removing the third fixing ring.

[0022] Optionally, the third fixing ring is provided with a third opening extending through the third fixing ring along its own axial direction.

[0023] By adopting the above technical solution, if the diameter of the connecting pipe is larger than that of the pipe body, in order to enable the first clamping piece to always be clamped against the inner wall of the connecting pipe, the third fixing ring is provided with a third opening along its own axial direction. Under the setting of the third opening, the third fixing ring can slide on the first connecting sleeve along the length direction of the first connecting sleeve. Since the outer diameter of the first connecting sleeve gradually decreases, the position of the third fixing ring on the first connecting sleeve can be adjusted according to the actual diameter of the connecting pipe, so that one side of the first clamping piece is always in contact with the inner wall of the connecting pipe.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application sets a connection assembly. When connecting pipes of different diameters (the diameter of the connecting pipe is larger than the diameter of the pipe opening of the pipe fitting body) are connected to the pipe fitting body, the first abutting piece slides along the radial direction of the pipe opening of the pipe fitting body until it fits against the inner wall of the connecting pipe, so that one side of the first abutting piece abuts against the inner wall of the connecting pipe to achieve connection between the connecting pipe and the pipe fitting body. By setting a slidable first abutting piece, the connection and installation between the pipe fitting body and connecting pipes of different diameters are achieved; 2. The present application sets a first opening of the first connecting sleeve and a second opening of the second fixing ring. When the distance between the first fixing ring and the second fixing ring is smaller, the second fixing ring is pressed toward the connecting pipe, and the first connecting sleeve is pressed toward the pipe body. The width of the first opening is smaller, so that the connection between the connecting pipe and the first connecting sleeve, and between the first connecting sleeve and the pipe body is tighter and firmer, thereby further improving the firmness of the connection between the connecting pipe and the pipe body. 3. The present application provides a locking assembly and rotates the locking member so that the limiting member is located in the slot of the locking member, thereby achieving locking and fixation of the first fixing ring and the second fixing ring.

In this embodiment, the pipe body 1 is provided with three pipe openings with different diameters. The first connecting sleeve 31 is sleeved on any pipe opening of the pipe body 1, and the pipe body 1 and the connecting pipe 2 are connected by the connecting assembly 3.

[0029] Reference Figure 1 and Figure 2When the diameter of the connecting pipe 2 is larger than the diameter of the pipe opening of the pipe body 1 connected thereto, that is, the pipe body 1 is located on the inner side of the connecting pipe 2, the first connecting sleeve 31 is also located on the inner side of the connecting pipe 2, the first connecting sleeve 31 is sleeved on the pipe body 1, and the first fastening member 32 slides along the radial direction of the pipe opening of the pipe body 1 until it fits with the inner wall of the connecting pipe 2, so that one side of the first fastening member 32 is pressed against the inner wall of the connecting pipe 2 to achieve the connection between the connecting pipe 2 and the pipe body 1; in order to further improve the sealing performance during water inflow, a first sealing ring 11 is sleeved on the end of the pipe body 1, and one side of the first sealing ring 11 fits with the inner wall of the connecting pipe 2, and the first sealing ring 11 seals the pipe body 1 and the connecting pipe 2. By setting the first fastening member 32, the first fastening member 32 improves the stability of the connection between the pipe body 1 and the connecting pipe 2, and reduces the shaking of the connecting pipe 2.

[0030] Reference Figure 3 In this embodiment, the first clamping member 32 is arc-shaped on the side away from the first connecting sleeve 31, and the arc-shaped opening is toward the side close to the first connecting sleeve 31. The arc-shaped first clamping member 32 fits against the inner wall of the connecting pipe 2, thereby increasing the contact area between the connecting pipe 2 and the pipe body 1, and further improving the stability between the connecting pipe 2 and the pipe body 1.

[0031] Reference Figure 2 and Figure 3 In order to enable the first clamping member 32 to adapt to connecting pipes 2 of different diameters (the diameter of the connecting pipe 2 is larger than the diameter of the pipe opening of the pipe fitting body 1), that is, to enable the first clamping member 32 to slide along the radial direction of the first connecting sleeve 31, the connecting assembly 3 also includes an elastic member 33, one end of the elastic member 33 is connected to the first connecting sleeve 31, and the other end is fixedly connected to the first clamping member 32. The elastic member 33 has a force to drive the first clamping member 32 to move away from the first connecting sleeve 31 under recoverable deformation. Under the action of the elastic member 33, the first clamping member 32 can always contact the inner wall of the connecting pipe 2 to fix the connecting pipe 2 to the pipe fitting body 1.

[0032] Reference Figure 4When the pipe body 1 is inserted into the connecting pipe 2, in order to further improve the stability of the connection between the connecting pipe 2 and the pipe body 1 and reduce the impact on the pipe body when the water flow is too large, causing the pipe body and the connecting pipe 2 to be separated, the end of the connecting pipe 2 close to the pipe body is coaxially sleeved with a first fixing ring 21, and the end of the first connecting sleeve 31 away from the first tightening member 32 is fixedly sleeved with a second fixing ring 311, and the outer diameter of the first connecting sleeve 31 gradually decreases in the direction away from the second fixing ring 311, and the first fixing ring 2 An inclined groove 211 is provided on one side close to the second fixing ring 311 along the length direction of the connecting pipe 2. When the pipe body 1 is inserted into the connecting pipe 2, the groove wall of the inclined groove 211 contacts and fits with the side wall of the first connecting sleeve 31, and the end wall of the first fixing ring 21 abuts against the end wall of the second fixing ring 311. During the abutting contact between the first fixing ring 21 and the second fixing ring 311, the connecting pipe 2 will be further compressed to improve the tightness between the connecting pipe 2 and the first connecting sleeve 31, thereby improving the tightness of the connection between the connecting pipe 2 and the pipe body 1.

[0033] Reference Figure 4 and Figure 5 When the first fixing ring 21 and the second fixing ring 311 are in contact, in order to further improve the firmness of the connection between the first connecting sleeve 31 and the pipe body 1, the first connecting sleeve 31 is penetrated and opened along its own axial direction with a first opening 312. When the distance between the first fixing ring 21 and the second fixing ring 311 is smaller, the second fixing ring 311 is pressed toward the side of the connecting pipe 2, and the first connecting sleeve 31 is pressed toward the side of the pipe body 1, and the width of the first opening 312 is smaller, so that the connection between the connecting pipe 2 and the first connecting sleeve 31, and the connection between the first connecting sleeve 31 and the pipe body 1 is tighter and firmer, thereby further improving the firmness of the connection between the connecting pipe 2 and the pipe body 1.

[0034] Reference Figure 4 and Figure 5 When the connecting pipe 2 is pressed toward the side of the first connecting sleeve 31, in order to make the second fixing ring 311 follow the first connecting sleeve 31 to synchronously press the pipe body 1, the second fixing ring 311 is penetrated along its own axial direction to open a second opening 3111, and the second opening 3111 is connected to the first opening 312, that is, the first opening 312 and the second opening 3111 are correspondingly arranged.

[0035] Reference Figure 6In order to further lock the pipe body 1 and the connecting pipe 2, the reducing tee pipe connector also includes a locking assembly 4. In some embodiments, the locking assembly 4 may be provided with one or more. In this embodiment, the locking assembly 4 is provided with one, and the locking assembly 4 includes a locking member 41 and a limiting member 42. The limiting member 42 is fixedly connected to the outer wall of the second fixing ring 311, and the locking member 41 is rotatably connected to the first fixing ring 21.

Specifically, the locking assembly 4 also includes a rotating shaft 43 and two mounting seats 44, each mounting seat 44 is fixedly connected to the outer wall of the first fixing ring 21, the rotating shaft 43 is rotatably connected between the two mounting seats 44, and the locking member 41 is fixedly connected to the rotating shaft 43. A slot 411 for accommodating the limiting member 42 is provided on the locking member 41; the locking member 41 rotates along an axial direction perpendicular to the first fixing ring 21 toward a side close to the limiting member 42 until the limiting member 42 is located in the slot 411, so as to realize the locking of the first fixing ring 21 and the second fixing ring 311.

[0036] Reference Figure 7 In order to facilitate the removal or replacement of the first clamping member 32, the connecting assembly 3 is connected to the first connecting sleeve 31 through the third fixing ring 5, the third fixing ring 5 is sleeved on the first connecting sleeve 31, and the first elastic member 33 is fixedly connected between the third fixing ring 5 and the first connecting sleeve 31.

[0037] Reference Figure 7 If the diameter of the connecting pipe 2 is larger than that of the pipe body 1, in order to enable the first fastening member 32 to always be in tight contact with the inner wall of the connecting pipe 2, the third fixing ring 5 is provided with a third opening 51 along its own axial direction. Under the setting of the third opening 51, the third fixing ring 5 can slide on the first connecting sleeve 31 along the length direction of the first connecting sleeve 31. Since the outer diameter of the first connecting sleeve 31 gradually decreases, the position of the third fixing ring 5 on the first connecting sleeve 31 can be adjusted according to the actual diameter of the connecting pipe 2, so that one side of the first fastening member 32 is always in contact with the inner wall of the connecting pipe 2.

[0038] In other installation scenarios, if the diameter of the connecting pipe 2 is smaller than the pipe body, the connecting assembly 3 can also be installed on the connecting pipe 2, and the first fixing ring 21 can be sleeved on the pipe body. The connecting pipe 2 is inserted into the pipe body so that one side of the first fastening member 32 abuts against the inner wall of the pipe body, which can also achieve the installation and fixation of the connecting pipe 2 and the pipe body.

[0039] The implementation principle of a reducing tee pipe connector in the embodiment of the present application is as follows: during installation, one pipe opening of the pipe main body 1 is inserted into the connecting pipe 2, and under the action of the elastic member 33, one side of the first tightening member 32 is fitted with the inner wall of the connecting pipe 2, and in the process of pushing the connecting pipe 2 toward the side of the pipe main body 1, the inclined groove 211 of the first fixing ring 21 further fits with the outer wall of the first connecting sleeve 31 until it cannot be pushed. During this process, the first connecting pipe 2 is pressed toward the side of the first connecting sleeve 31, and the first connecting sleeve 31 further presses the pipe main body 1, thereby realizing the tight fixation between the connecting pipe 2 and the first connecting sleeve 31, and the tight fixation between the first connecting sleeve 31 and the pipe main body 1, and rotating the locking member 41 so that the limiting member 42 is clamped in the clamping groove 411 of the locking member 41, so as to realize the locking fixation of the first connecting sleeve 31 and the first fixing ring 21, thereby realizing the connection and fixation between the pipe main body 1 and the connecting pipe 2.
