Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and more specifically, to a quick pipe fitting. Background Technology

[0002] Pipe fittings are connecting tools between pipes. They are detachable connection points between components and pipes, allowing liquid in one pipe to flow into another. However, the positions of the two ends of existing pipe fittings are relatively fixed, resulting in a fixed connection angle. This means that the positions of the two pipes installed at both ends of the pipe fitting are relatively fixed, making it impossible to adjust the connection angle at both ends of the pipe fitting according to actual installation and connection requirements, which is quite inconvenient.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick pipe coupling.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick pipe connector, comprising a housing 1 and a housing 2, wherein the interior of housing 1 and the interior of housing 2 respectively form a cavity 1 and a cavity 2, the cavity 1 and the cavity 2 are interconnected, an inlet pipe connected to the outer wall of housing 1 and communicating with cavity 1 is fixedly connected, and an outlet pipe connected to cavity 2 is fixedly connected to the outer wall of housing 2, wherein housing 1 and housing 2 are relative to each other through an adjustment assembly, and the relative rotation of housing 1 and housing 2 is used to adjust the angle between the axial direction of the inlet pipe and the axial direction of the outlet pipe.

[0006] Preferably, an inner mounting ring that communicates with cavity one is fixedly connected to the side of housing one near housing two, and an outer mounting ring is fixedly connected to housing two. The inner mounting ring is rotatably mounted on the inner circumferential wall of the outer mounting ring and the two are coaxially arranged. One end of the inner mounting ring communicates with cavity two, and one end of the outer mounting ring abuts against the side of housing one near housing two. The adjustment components are respectively arranged on the outer mounting ring and housing one.

[0007] Preferably, the adjustment assembly includes a ratchet, a pawl, and a leaf spring. The ratchet is fixedly connected to the outer peripheral wall of the mounting outer ring and the two are coaxially arranged. The pawl is rotatably connected to the side of housing one near housing two. The leaf spring is disposed on the side of housing one near housing two and abuts against one side of the pawl to keep the pawl engaged with the ratchet.

[0008] Preferably, a rotating ring is fixedly connected to the outer peripheral wall of the mounting inner ring, the rotating ring being coaxial with the mounting inner ring, and a rotating groove is formed on the inner peripheral wall of the mounting outer ring to accommodate the rotation of the rotating ring.

[0009] Preferably, a sealing ring is fixedly connected to the inner wall of the rotating groove, and the sealing ring abuts against the rotating ring.

[0010] Preferably, an installation ring is fixedly connected to the inner peripheral wall of the liquid inlet pipe, a filter plate is provided on the installation ring, and an annular groove is opened on the side of the installation ring away from the cavity. An annular ring for embedding in the annular groove is fixedly connected to the filter plate.

[0011] In summary, this utility model has the following beneficial effects: This solution sets up a housing 1 and a housing 2, and forms interconnected cavities 1 and 2 within the housing 1 and housing 2 respectively. The inlet pipe and the outlet pipe are respectively installed on the housing 1 and housing 2. The user holds the housing 1 or housing 2 and rotates the housing 1 or housing 2 by adjusting the components. When the housing 1 rotates, it drives the inlet pipe to rotate, and when the housing 2 rotates, it drives the outlet pipe to rotate, causing the angle between the axial direction of the inlet pipe and the axial direction of the outlet pipe to change. The axial angle between the two can be gradually increased or gradually decreased. Thus, by rotating the housing 1 or housing 2, the angle between the axial direction of the inlet pipe and the axial direction of the outlet pipe can be adjusted, and the installation connection angle of the inlet pipe and the outlet pipe can be adjusted to meet the installation connection requirements of the two pipes at some different positions.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] A type of quick-connect pipe fitting, such as Figures 1 to 5 As shown, the device includes a housing 1 and a housing 2. The interiors of housing 1 and housing 2 respectively form cavities 3 and 4, which are interconnected. An inlet pipe 5, connected to cavity 3, is welded to the outer wall of housing 1. An outlet pipe 6, connected to cavity 4, is welded to the outer wall of housing 2. Housing 1 and housing 2 can rotate relative to each other via an adjusting assembly 7. This relative rotation adjusts the angle between the axial direction of the inlet pipe 5 and the outlet pipe 6. An inner mounting ring 8, connected to cavity 3, is welded to the side of housing 1 closest to housing 2. An outer mounting ring 9 is welded onto the housing 2. An inner mounting ring 8 is rotatably mounted on the inner circumferential wall of the outer mounting ring 9, and the two are coaxially arranged. One end of the inner mounting ring 8 is connected to the cavity 4. One end of the outer mounting ring 9 abuts against the side of the housing 1 near the housing 2. Adjustment components 7 are respectively arranged on the outer mounting ring 9 and the housing 1. An mounting ring 13 is welded onto the inner circumferential wall of the liquid inlet pipe 5. The mounting ring 13 is coaxially arranged with the liquid inlet pipe 5. A filter plate 14 is mounted on the mounting ring 13. An annular groove 15 is opened on the side of the mounting ring 13 away from the cavity 3. An annular ring 16 for embedding in the annular groove 15 is welded onto the filter plate 14.

[0021] The adjusting assembly 7 includes a ratchet 701, a pawl 702, and a leaf spring 703. The ratchet 701 is welded to the outer peripheral wall of the mounting outer ring 9 and the two are coaxially arranged. The pawl 702 is rotatably connected to the side of the housing 1 near the housing 2 via a rotating shaft. One side of the leaf spring 703 is partially bonded to the side of the housing 1 near the housing 2. The leaf spring 703 abuts against one side of the pawl 702 so that the pawl 702 and the ratchet 701 are engaged. The unbonded part of the pawl 702 abuts against the leaf spring 703. A rotating ring 10 is welded to the outer peripheral wall of the mounting inner ring 8. The rotating ring 10 is coaxially arranged with the mounting inner ring 8. A rotating groove 11 is opened on the inner peripheral wall of the mounting outer ring 9 to accommodate the rotation of the rotating ring 10. A sealing ring 12 is bonded to the inner wall of the rotating groove 11. The sealing ring 12 and the rotating ring 10 abut against each other.

[0022] The user holds housing 2 and rotates it clockwise. As housing 2 rotates clockwise, it drives the outer ring 9, ratchet 701, and outlet pipe 6 to rotate. During rotation, ratchet 701 drives pawl 702 to rotate. Pawl 702 rotates on the side of housing 1 closest to housing 2, initially moving away from ratchet 701 until it contacts leaf spring 703. At this point, pawl 702 pushes the unattached end of leaf spring 703, causing it to deform. This disengages pawl 702 from one of the ratchet teeth in ratchet 701, and then leaf spring 703... The elastic recovery pushes the pawl 702, causing it to rotate towards the ratchet 701 until it engages with other teeth in the ratchet 701. When housing 2 is not rotated, the engagement of the pawl 702 and ratchet 701 keeps both housing 1 and housing 2 stationary. As housing 2 rotates clockwise, it drives the outlet pipe 6 to rotate, gradually reducing the angle between the axial direction of the outlet pipe 6 and the inlet pipe 5 until they are on the same side of housing 2 and housing 1, and the axial direction of the inlet pipe 5 is relatively parallel to the axial direction of the outlet pipe 6. At this point, it can be used to install the pipe located on housing 1. Two pipes on the same side as housing 2 are installed. Then, housing 2 is rotated further, causing the outlet pipe 6 to rotate. At this point, the angle between the axial direction of the outlet pipe 6 and the axial direction of the inlet pipe 5 gradually increases until the outlet pipe 6 and the inlet pipe 5 are located on opposite sides of housing 2 and housing 1, and the axial direction of the inlet pipe 5 is relatively parallel to the axial direction of the outlet pipe 6. This is suitable for installing two pipes located on opposite sides of housing 1 and housing 2. Simultaneously, as housing 2 rotates clockwise, it causes the outer ring 9 to rotate. At this time, the rotating ring 10 and the sealing ring 12 are pressed together, and the rotating ring 10 rotates within the rotating groove 11. The rotation of the rotating ring 10 within the rotating groove 11 prevents the installation of the outer ring 9 from being obstructed. During rotation, the inner ring 8 disengages from the inner ring 9, increasing the stability of the housing 1 and housing 2 when they rotate relative to each other. The mutual abutment of the rotating ring 10 and the sealing ring 12 also increases the sealing between the outer ring 9 and the inner ring 8. Then, the two pipes are connected to the inlet pipe 5 and the outlet pipe 6 respectively. The user can adjust the position of the outlet pipe 6 by rotating the housing 2, and adjust the included angle between the axial direction of the inlet pipe 5 and the outlet pipe 6. This allows for convenient and quick adjustment of the installation connection angle of the inlet pipe 5 and the outlet pipe 6, meeting the installation connection requirements of the two pipes in different positions.

[0023] After the user connects the two pipes to the inlet pipe 5 and the outlet pipe 6 respectively, when liquid is introduced into the pipe connected to the inlet pipe 5, the liquid will gradually flow into the inlet pipe 5 and filter the impurities in the liquid through the filter plate 14. After the liquid is filtered by the filter plate 14, it flows from the inlet pipe 5 into cavity 3. Then the liquid flows from cavity 3 through the inner ring 8, cavity 4 and outlet pipe 6 in sequence. Then the liquid enters the pipe connected to the outlet pipe 6. When the filter plate 14 needs to be cleaned, first disconnect the pipe connected to the inlet pipe 5, and then move the filter plate 14 away from cavity 3. When the filter plate 14 moves, it drives the annular ring 16, causing the annular ring 16 to disengage from the annular groove 15. Then the filter plate 14 and the annular ring 16 are removed from the inlet pipe 5 and the filter plate 14 is cleaned.

All technical solutions falling within the scope of this utility model's concept are protected.
