Technical Field

[0001] The utility model relates to the technical field of drainage pipe straight-through pieces, in particular to a drainage pipe straight-through connecting piece. Background Art

[0002] Drain pipe straight connector is a pipe fitting used to connect two straight drain pipes. Its function is to achieve direct access of indoor drainage to the drainage pipe system without damaging obstacles. This type of pipe fitting generally adopts a socket connection method, and is provided with an upper socket joint, a short straight pipe, a swirl body and a lower socket joint from top to bottom. Drain pipe straight fittings are very important in the process of house decoration and construction, especially when obstacles such as walls or roofs block the connection between other indoor areas and outdoor drainage pipes. Drain pipe straight fittings are particularly important. It can not only improve drainage efficiency and reduce sewage retention time, but also reduce the difficulty and cost of maintaining and repairing sewage pipes inside the house.

[0003] However, during the drainage process, impurities in the water cannot be filtered out by the current drain pipe straight-through fittings, which can easily cause blockage at one end of the drainage. At the same time, when the water discharged from the drain pipe can be reused, many drain pipes currently do not have enough water pressure, and the water pressure is insufficient when used for spraying, which affects the spraying effect. Utility Model Content

[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a drainage pipe straight-through connector, which can effectively solve the technical problems that the current water pipe straight-through connector cannot filter impurities and cannot adjust water pressure.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, the utility model provides a drain pipe straight-through connector, which is mainly used for connecting between drain pipes, and through the connector, impurities in the water pipe are filtered and the water pressure of the water pipe is increased. Its specific structure mainly includes a hollow pipe body 1, one end of the pipe body 1 is connected to an inlet flange 2, and the other end is connected to an outlet flange 3, the inlet flange 2 and the outlet flange 3 are both connected to the inside of the pipe body 1, the inlet flange 2 is used to connect one end of the inlet pipe, and the outlet flange 3 is used to connect one end of the outlet pipe, and the outer diameters of the inlet flange 2 and the outlet flange 3 at both ends are smaller than the outer diameter of the pipe body 1. In order to better connect with the corresponding water pipe, an external threaded portion 11 that is convenient for connection is provided on the outside of the inlet flange 2 and the outlet flange 3, and the outer side surface of the pipe body 1 adopts a hexagonal structure for convenient connection and anti-slip.

[0026] According to the position of water flow inside the pipe body 1, a structure with one end larger than the other end is adopted to automatically adjust the water pressure. The inner diameter of the pipe body 1 gradually decreases from the water inlet flange 2 to the water outlet flange 3, that is, the water flows from the end with a larger opening of the pipe body 1 to the end with a smaller opening. After the water flows converge in the pipe body 1, a greater water pressure is formed and then flows out. Therefore, after using this connector, the situation of insufficient water pressure during inflow can be met.

[0027] A card slot 4 is coaxially arranged on the inner wall of the water inlet flange 2, and the card slot 4 is communicated with the open end of the water inlet flange 2. A filter screen 5 is also arranged in the water inlet flange 2, and the filter screen 5 is connected with a snap ring 6 fixed in the card slot 4 around it. The filter screen 5 is assembled at one end of the water inlet flange 2 to filter the water flowing through, and the water enters the end of the water outlet flange 3 with a smaller opening after filtering to prevent clogging by impurities. The filter screen 5 is fixed in the card slot 4 by the snap rings 6 around it, and a circular ring 9 is added at the open end of the card slot 4 to reinforce the position of the filter screen 5, and effectively prevent the filter screen 5 from falling off along the open end of the card slot 4.

[0028] At the position where the snap ring 6 is fixed in the slot 4, the snap ring 6 is provided with two through holes 7. Correspondingly, at the connection between the slot 4 and the snap ring 6, two protrusions are inserted into the corresponding through holes 7 to fix the snap strips 8. After the filter 5 is fixed in the corresponding snap strips 8 by the snap ring 6, it will not fall off or move at will. At this time, the height of the through hole 7 should be equal to the length of the snap strip 8, and the snap strip 8 will not be pushed out to cause the filter 5 to move.

[0029] The clamping ring 6 is fixed inside the clamping groove 4, and a circular ring 9 is also installed at the opening of the clamping groove 4, which is pressed and fixed to one end of the clamping ring 6 against the inner wall. After the circular ring 9 is assembled, it is pushed out toward the open end of the water inlet flange 2. The pushed-out position is also provided with a plurality of grooves 12 distributed on the side. The user can use the grooves 12 to pull out the circular ring 9 for maintenance or replacement.

[0030] An anti-idiot part 10 is provided between the circular ring 9 and the slot 4, which provides a designated connection direction on the one hand and tightens the fixation between the two on the other hand. The specific structure of the anti-idiot part 10 mainly includes at least one anti-idiot groove 1001 provided on the inner wall of the slot 4 and at least one anti-idiot block 1002 protruding from the surface of the snap ring 6, and the anti-idiot block 1002 is clamped into the corresponding anti-idiot groove 1001 and fixed.

[0031] Compared with the traditional technology, the present technical solution adds a filter screen 5 inside the water inlet flange 2 at the water inlet end of the pipe body 1. The filter screen 5 filters the water flow before it rolls into the pipe body 1, effectively removing the impurities remaining in the water flow and avoiding the blockage of the pipe body 1 and the water outlet flange 3. At the same time, the pipe body 1 adopts a structure in which the opening gradually becomes smaller, which has the effect of increasing the water pressure.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
