Technical Field

[0001] The invention relates to the technical field of pipeline connectors, and in particular to an indoor water supply and drainage pipeline connector. Background Art

[0002] The function of indoor water pipe connectors is mainly to ensure that some pipes above the room can be tightly connected with the sewer pipes to facilitate normal drainage work. For example, the drainage pipe at the bottom of the washbasin needs to be connected to the sewer pipe using a pipe connector.

[0003] However, the rubber sealing sleeve at the bottom of the existing pipe connector does not have the effect of adjusting the tightness, which makes the opening of the rubber sealing sleeve very tight, so that the entire pipe connector cannot be quickly connected to the sewer pipe during installation, and cannot be quickly disassembled when the sewer pipe is modified or replaced. Therefore, we propose a new indoor water pipe connector. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an indoor water pipe connector, which effectively solves the problem that the rubber sealing sleeve at the bottom of the existing pipe connector does not have the effect of adjusting the tightness, which causes the opening of the rubber sealing sleeve to be very tight, so that the entire pipe connector cannot be quickly connected to the sewer pipe during installation, and cannot be quickly disassembled when the sewer pipe is modified and replaced.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An indoor water pipe connector comprises a fixed shell with a rubber sealing sleeve fixedly connected at the bottom, a water pipe is sleeved on the rubber sealing sleeve, and further comprises a sealing sleeve tightness adjustment mechanism, a telescopic pipe connection mechanism, an angle-adjustable pipe connection mechanism and a detachable filtering mechanism;

[0007] The sealing sleeve tightness adjustment mechanism comprises a guide assembly, a mounting frame fixedly connected to the front outer wall of the fixed shell, a bidirectional screw rotatably mounted in the mounting frame, two movable rods symmetrically screwed on two opposite threaded ends of the bidirectional screw, and two C-shaped adjustment plates symmetrically fixed to the outer walls of adjacent sides of the two movable rods;

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Example 1, reference Figure 1-4 , an indoor water pipe connector, comprising a fixed shell 1 with a rubber sealing sleeve 2 fixedly connected at the bottom and a sealing sleeve tightness adjustment mechanism, wherein a water pipe 32 is sleeved on the rubber sealing sleeve 2;

[0035] Specifically, the sealing sleeve tightness adjustment mechanism includes a guide assembly, a mounting frame 3 fixedly connected to the front outer wall of the fixed shell 1, a bidirectional screw 4 rotatably mounted in the mounting frame 3, two movable rods 5 symmetrically screwed on two opposite threaded ends of the bidirectional screw 4, and two C-shaped adjustment plates 6 symmetrically fixed to the outer walls of the adjacent sides of the two movable rods 5;

[0036] Furthermore, the guide assembly includes a fixing frame 8 fixedly connected to the rear outer wall of the fixing shell 1, a guide shaft 9 fixedly connected to the fixing frame 8, and two guide sleeves 10 fixedly embedded in the two movable rods 5 in sequence, and the two guide sleeves 10 are both slidably connected to the guide shaft 9;

[0037] Furthermore, the outer walls of the adjacent sides of the two C-shaped adjusting pieces 6 are fixed to the outer wall of the rubber sealing sleeve 2, and the outer wall of one end of the bidirectional screw 4 is fixedly connected to a No. 1 rotating cap 7;

[0038] In the specific implementation of this embodiment: first, the bidirectional screw 4 is driven to rotate forwardly through the No. 1 rotating cap 7, and then under the guiding effect of the guide assembly, the two movable rods 5 threadedly connected with the bidirectional screw 4 will drive the two C-shaped adjustment pieces 6 to move away from each other. At this time, the two C-shaped adjustment pieces 6 can pull the rubber sealing sleeve 2 outward, and the tightness of the opening of the rubber sealing sleeve 2 can be flexibly adjusted, so that the entire pipe connector can be quickly sleeved on the sewer pipe 32;

[0039] Secondly, after the pipe connector is sleeved onto the sewer pipe 32, the bidirectional screw 4 is driven to rotate in the opposite direction through the No. 1 rotating cap 7. Subsequently, under the guiding effect of the guide assembly, the two movable rods 5 threadedly connected to the bidirectional screw 4 will drive the two C-shaped adjusting pieces 6 to move closer to each other. At this time, the two C-shaped adjusting pieces 6 can squeeze the rubber sealing sleeve 2 inward, which makes it easier for the rubber sealing sleeve 2 to be tightly connected to the sewer pipe 32, thereby helping to improve the sealing effect.

[0040] Example 2, reference Figure 1 , Figure 3 and Figure 5-8 , this embodiment is optimized on the basis of embodiment 1, specifically: an indoor water pipe connector, further comprising a telescopic pipe connection mechanism and an angle-adjustable pipe connection mechanism;

[0042] Furthermore, four annularly distributed sealing strips 17 are fixedly connected to the circumferential outer wall of the telescopic sleeve 16, and the inner wall of the fixed tube 11 is provided with sealing slots 18 adapted to the four sealing strips 17. The four sealing strips 17 are respectively movably inserted into the four sealing slots 18. The sealing cooperation between the four sealing strips 17 and the four sealing slots 18 can ensure the sealing performance of the telescopic sleeve 16 during the telescopic process in the fixed tube 11.

[0043] Furthermore, a slideway 19 is provided on one side of the positioning frame 12, the outer wall of the adjusting rod 14 is slidably connected to the inner wall of the slideway 19, and a second rotating cap 15 is fixedly connected to the outer wall of the bottom end of the adjusting screw 13;

[0045] Furthermore, the pawl 23 and the ratchet wheel 22 are meshed with each other, and a connecting spring 25 is fixedly connected between the pawl 23 and the connecting block 24;

[0046] Furthermore, the bottom end of the connecting pipe 21 is connected to the top inner wall of the telescopic sleeve 16 through a sealing bearing, and the top end of the connecting pipe 21 is fixedly connected to the upper water pipe 31 through a sealing clamp 26;

[0048] Secondly, after the height adjustment of the connecting pipe 21 is completed, the connecting pipe 21 can be rotated, and during the rotation process, the self-locking performance of the ratchet 22 and the pawl 23 can ensure the stability of the connecting pipe 21 after the angle adjustment is completed, so that the connection angle of the connecting pipe 21 can be flexibly adjusted, so as to facilitate better and more stable connection with the upper water pipe 31 at different angles, so as to better adapt to the pipeline connection requirements in different situations, and further improve the adaptability of the pipeline connector.

[0049] Example 3, reference Figure 2 and Fig. 9 , This embodiment is optimized on the basis of embodiment 1, specifically: an indoor water pipe connector, further comprising a detachable filtering mechanism;

At this time, the wastewater discharged into the sewer pipe 32 can be fully filtered through the filter element 28, which can effectively prevent the sewer pipe 32 from being blocked by impurities. After a period of use, the filter element 28 installed in the installation frame 27 can be pulled out by pulling out the iron plate 29 for regular cleaning or replacement.
