Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a method for constructing drainage pipes. Background Technology

[0002] Drainage pipes are an important building facility, mainly used to collect and discharge liquid waste such as rainwater, wastewater and domestic sewage. They are usually made of corrosion-resistant and wear-resistant materials. The design of drainage pipes takes into account the principles of fluid mechanics to ensure that wastewater can flow smoothly and efficiently, avoiding blockage and water accumulation. Their structures are diverse, including straight pipes, elbows, tees, crosses, etc., to adapt to different installation requirements and spatial layouts.

[0003] Because drainage pipes are laid through multiple building structures, existing plastic drainage pipes, when connected via multi-way pipes, are typically connected by simply applying glue to one end of a straight pipe and inserting it into one end of the multi-way pipe. However, this method creates a strong bond between the straight and multi-way pipes, making them difficult to separate. If a section of the pipe is damaged, the entire pipe needs to be replaced, rather than just the damaged part, increasing maintenance costs and difficulty. Furthermore, some pipes, even with threaded connections and sealing rings, may leak due to the aging of the sealing rings. Utility Model Content

[0004] The purpose of this utility model is to provide a method for constructing drainage pipes that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drainage pipe is constructed, including an elbow and a straight pipe. The elbow has two slots on its inner side, and the two slots are respectively close to one end of the elbow. Pipe edges are fixedly installed at both ends of the elbow. A first fixing ring is movably installed on the outer side of the straight pipe. A threaded groove is opened on the inner side of the first fixing ring. A collar is movably installed in the first fixing ring near the threaded groove. A second fixing ring is fixedly installed on the outer side of the collar. A top ring is provided on one side of the second fixing ring. Multiple fixing shafts are fixedly installed on the top ring relative to the side of the second fixing ring, and the multiple fixing shafts are inserted into corresponding through holes in the second fixing ring.

[0007] As a further preferred embodiment of this utility model, one end of the straight pipe is inserted into a slot at one end of the elbow, and a sealing ring is also inserted between the straight pipe and one side of the slot. Inserting the straight pipe into the slot can achieve the initial connection between the straight pipe and the elbow, and the sealing ring can achieve the first seal between the straight pipe and the slot.

[0008] As a further preferred embodiment of this utility model, a first inclined groove is provided on the inner side of the pipe.

[0009] As a further preferred embodiment of this utility model, a second inclined groove is also provided in the first fixing ring near the screw groove, and the first fixing ring is inserted through the outside of the straight pipe.

[0010] As a further preferred embodiment of this utility model, a first rubber ring is fixedly installed on one side of the collar, and a second rubber ring is fixedly installed on the other side of the collar. The upper surfaces of the first rubber ring and the second rubber ring are respectively provided with inclined surfaces, and the collar, the first rubber ring, and the second rubber ring are also inserted through the outside of the straight pipe.

[0011] As a further preferred embodiment of this utility model, the sides of the plurality of second fixing rings away from the top ring are respectively fixedly installed in the screw groove. A compression spring is also fitted on the outside of the fixing shaft. One side of the compression spring abuts against one side of the second fixing ring, and the other side of the compression spring abuts against one side of the sealing ring. One side of the first fixing ring is threaded to the pipe edge through the screw groove. The outer side of the second rubber ring is inserted into the first inclined groove. After the first fixing ring is threaded to the pipe edge through the screw groove, the compression of the first rubber ring by the second inclined groove and the compression of the second rubber ring at the bottom of the first inclined groove can be used to make the first rubber ring and the second rubber ring respectively subject to pressure in the direction of the straight pipe. This pressure is used to fix one end of the straight pipe in the slot and to achieve the second and third seals.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a first fixing ring is provided on the outside of the straight pipe, which includes a collar, a second fixing ring, a top ring, and a fixing shaft. First and second rubber rings are provided on both sides of the collar. After the straight pipe is inserted into the elbow slot, the first fixing ring is connected to the pipe thread through a screw groove. The two rubber rings are squeezed by the inclined groove to achieve sealing and fixing. At the same time, the compression spring pushes the second fixing ring, which, together with the collar, continuously pushes the second rubber ring into the first inclined groove to prevent the rubber ring from forming gaps due to deformation, ensuring long-lasting sealing, facilitating pipe section replacement, and extending service life.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-4 As shown, the present invention provides a drainage pipe, including an elbow 1 and a straight pipe 2. Two slots 3 are opened on the inner side of the elbow 1, and the two slots 3 are respectively close to one end of the elbow 1. Pipe edges 4 are fixedly installed at both ends of the elbow 1. A first fixing ring 5 is movably installed on the outer side of the straight pipe 2. A screw groove 6 is opened on the inner side of the first fixing ring 5. A collar 7 is movably installed in the first fixing ring 5 near the screw groove 6. A second fixing ring 8 is fixedly installed on the outer side of the collar 7. A top ring 9 is provided on one side of the second fixing ring 8. Multiple fixing shafts 10 are fixedly installed on the top ring 9 relative to the side of the second fixing ring 8, and the multiple fixing shafts 10 are inserted into the corresponding through holes in the second fixing ring 8.

[0021] like Figures 2-3 As shown, one end of the straight pipe 2 is inserted into the slot 3 at one end of the elbow 1, and a sealing ring 16 is also inserted between the straight pipe 2 and one side of the slot 3. Inserting the straight pipe 2 into the slot 3 can achieve the initial connection between the straight pipe 2 and the elbow 1, and the sealing ring 16 can achieve the first seal between the straight pipe 2 and the slot 3. A first inclined groove 11 is opened on the inner side of the pipe edge 4.

[0022] like Figures 1-4As shown, a second inclined groove 12 is also provided inside the first fixing ring 5 near the screw groove 6, and the first fixing ring 5 is inserted through the outside of the straight pipe 2. A first rubber ring 13 is fixedly installed on one side of the collar 7, and a second rubber ring 14 is fixedly installed on the other side of the collar 7. Inclined surfaces are provided on the upper surfaces of the first rubber ring 13 and the second rubber ring 14 respectively. The collar 7, the first rubber ring 13, and the second rubber ring 14 are also inserted through the outside of the straight pipe 2. The sides of multiple second fixing rings 8 away from the top ring 9 are respectively fixedly installed in the screw groove 6. A compression spring 15 is also fitted on the outside of the fixing shaft 10. One side of the compression spring 15 abuts against one side of the second fixing ring 8. 5. On the other side, it abuts against the inner side of the sealing ring 16. One side of the first fixing ring 5 is threaded to the pipe edge 4 through the screw groove 6. The outer side of the second rubber ring 14 is inserted into the first inclined groove 11, and the outer side of the first rubber ring 13 is inserted into the second inclined groove 12. After the first fixing ring 5 is threaded to the pipe edge 4 through the screw groove 6, the first rubber ring 13 can be squeezed by the second inclined groove 12 and the second rubber ring 14 at the bottom of the first inclined groove 11, so that the first rubber ring 13 and the second rubber ring 14 are respectively subjected to pressure in the direction of the straight pipe 2. This pressure is used to fix one end of the straight pipe 2 in the slot 3 and to achieve the second and third seals.

[0023] It should be noted that this utility model is for constructing a drainage pipe. When connecting the elbow 1 and the straight pipe 2, a sealing ring 16 can be first inserted and installed on one side of the slot 3, and one end of the straight pipe 2 can be inserted into the slot 3. Then, the first fixing ring 5 is moved outside the straight pipe 2, and the first fixing ring 5 drives the second fixing ring 8 and the collar 7 to move synchronously outside the straight pipe 2 through multiple fixing shafts 10. This allows the first fixing ring 5 to be gradually screwed into the pipe edge 4 through the screw groove 6. When the first fixing ring 5 is gradually screwed into the pipe edge 4, the second inclined groove 12 on the inner side of the first fixing ring 5 moves on the first rubber ring 13 and applies pressure to the first rubber ring 13. Simultaneously, the first fixing ring 5 pushes the slot 3 and cooperates with the collar 7 to allow the second rubber ring 14 to be gradually inserted into the first inclined groove 11. Thus, the second inclined groove 12 and the first rubber ring 14 are used to achieve the desired effect. 3. The dimensional difference between the first inclined groove 11 and the second rubber ring 14 causes the first rubber ring 13 and the second rubber ring 14 to be subjected to pressure in the direction of the straight pipe 2. Thus, the pressure of the first rubber ring 13 and the second rubber ring 14 on the straight pipe 2 fixes the straight pipe 2 in the collar 7, the first rubber ring 13, and the second rubber ring 14. In conjunction with the second fixing ring 8, one end of the straight pipe 2 is fixed in the slot 3. Thus, the sealing ring 16, the second rubber ring 14, and the first rubber ring 13 achieve a triple seal while connecting the straight pipe 2 and the elbow 1. In addition, the compression springs 15 on the outside of the multiple fixing shafts 10 continuously apply a moving pushing force to the second fixing ring 8 in the direction of the pipe 4. Thus, in conjunction with the collar 7, the second rubber ring 14 is kept under a certain pressure in the first inclined groove 11, thereby ensuring the stability of the connection and sealing between the elbow 1 and the straight pipe 2.
