Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, in particular to a water supply and drainage pipeline connection device. Background Technique
[0002] In water supply and drainage projects, a large number of pipelines are required. When connecting pipelines, pipeline connectors are often needed. Existing pipeline connectors are all fixed to the pipelines using threads. However, their shock absorption performance is poor. Since the water flow is likely to cause impact vibration to the pipelines during the water conveyance process, and the thread connection is likely to become loose under the action of long-term vibration, the sealing performance is reduced, resulting in water leakage. Therefore, in view of the above current situation, there is an urgent need to develop a water supply and drainage pipeline connection device with good sealing performance, good shock absorption performance, and more stable connection to overcome the deficiencies in current practical applications and meet the current requirements. Content of the Utility Model
[0003] The purpose of the utility model is to provide a water supply and drainage pipeline connection device to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A water supply and drainage pipeline connection device includes a connector, a drainage pipeline, a sealing mechanism, bolts, nuts and a shock absorption mechanism. One drainage pipeline is detachably fixed on each of the left and right sides of the connector. The connector includes: an inner pipe section, an outer pipe section and a positioning retaining ring. One outer pipe section is fixed on each of the left and right sides of the inner pipe section. A positioning retaining ring is fixed at the middle position inside the inner pipe section. One sealing mechanism is detachably fixed at each of the left and right ends of the connector. The sealing mechanism includes: a mounting ring and a sealing ring. The mounting ring and the sealing ring are fixed together. The outer shape of the sealing ring is frustum-shaped. The outer diameter of the left end of the sealing ring is smaller than the inner diameter of the outer pipe section, and the outer diameter of the right end of the sealing ring is larger than the inner diameter of the outer pipe section. The number of shock absorption mechanisms is two. The shock absorption mechanisms are fixed inside the outer pipe section. The drainage pipeline passes through the shock absorption mechanisms. The shock absorption mechanism includes: a vibration isolation pad, an outer housing and friction balls. The vibration isolation pad is fixed inside the outer pipe section. The outer housing is fixed on the inner side of the vibration isolation pad. A plurality of friction balls are movably installed inside the outer housing.
[0006] Preferably: The outer wall of the drainage pipeline is in sliding contact with the inner wall of the outer housing.
[0007] Preferably: Internal threads are provided inside the inner pipe section, external threads are provided at the front end of the drainage pipeline, and the internal threads and the external threads are meshed with each other.
[0008] Preferably: The diameter of the outer pipe section is larger than the outer diameter of the drainage pipeline.
[0009] Preferably, the mounting ring is detachably fixed to the outer pipe section by bolts and nuts.
[0010] Preferably, the mounting ring is made of a metal material, and the sealing ring is made of rubber.
[0011] Preferably, the inner diameter of the sealing ring is the same as the outer diameter of the drainage pipe.
[0012] The beneficial effects of the present utility model are as follows: When using this water supply and drainage pipe connection device, the drainage pipe is passed through the sealing ring and tightened into the inner pipe section until the front end of the drainage pipe abuts against the positioning retaining ring. Then, the sealing ring is inserted into the outer pipe section, and the mounting ring and the outer pipe section are fixed together by bolts and nuts. Since the outer diameter of the left end of the sealing ring is smaller than the inner diameter of the outer pipe section, the sealing ring can be inserted into the outer pipe section. And the outer diameter of the right end of the sealing ring is larger than the inner diameter of the outer pipe section. After the sealing ring is completely inserted into the outer pipe section, its right end is squeezed, so that the sealing ring fits tightly with the drainage pipe, thereby improving the sealing performance and preventing water leakage. When the water flow impacts the drainage pipe, the drainage pipe transmits the vibration to the outer housing, and through the outer housing, the vibration is transmitted to a plurality of friction balls, causing the plurality of friction balls to rub against each other, thereby converting the vibration force into frictional force and consuming it. At the same time, the vibration is isolated to a certain extent by the vibration isolation pad, thereby reducing the vibration transmitted to the connector and further improving the connection stability. In summary, the present utility model has good sealing performance, good shock absorption performance, and more stable connection. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] The following gives specific embodiments.
[0024] See Figures 1 to 7, in the embodiment of the present utility model, a water supply and drainage pipe connection device includes a connector 1, a drainage pipe 2, a sealing mechanism 3, bolts 4, nuts 5 and a shock absorption mechanism 6. A drainage pipe 2 is detachably fixed on each of the left and right sides of the connector 1. The connector 1 includes an inner pipe section 101, an outer pipe section 102 and a positioning retaining ring 103. An outer pipe section 102 is fixed on each of the left and right sides of the inner pipe section 101. A positioning retaining ring 103 is fixed at the middle position inside the inner pipe section 101. An internal thread 1011 is provided inside the inner pipe section 101. An external thread 201 is provided at the front end of the drainage pipe 2. The internal thread 1011 and the external thread 201 are meshed with each other, so that the drainage pipe 2 and the inner pipe section 101 are fixed together. The diameter of the outer pipe section 102 is larger than the outer diameter of the drainage pipe 2, so that there is a certain gap between the outer pipe section 102 and the drainage pipe 2 for installing other parts. A sealing mechanism 3 is detachably fixed at each of the left and right ends of the connector 1. The sealing mechanism 3 includes a mounting ring 301 and a sealing ring 302. The mounting ring 301 is detachably fixed to the outer pipe section 102 through bolts 4 and nuts 5. The mounting ring 301 and the sealing ring 302 are fixed together. The mounting ring 301 is made of a metal material. The sealing ring 302 is made of rubber. The inner diameter of the sealing ring 302 is the same as the outer diameter of the drainage pipe 2. The outer shape of the sealing ring 302 is frustum-shaped. The outer diameter of the left end of the sealing ring 302 is smaller than the inner diameter of the outer pipe section 102, so that the sealing ring 302 can be inserted into the outer pipe section 102. The outer diameter of the right end of the sealing ring 302 is larger than the inner diameter of the outer pipe section 102, so that after the sealing ring 302 is completely inserted into the outer pipe section 102, its right end is extruded, so that the sealing ring 302 is tightly attached to the drainage pipe 2, thereby improving the sealing performance. The number of the shock absorption mechanisms 6 is two. The shock absorption mechanisms 6 are fixed inside the outer pipe section 102. The drainage pipe 2 passes through the shock absorption mechanisms 6. The shock absorption mechanism 6 includes a vibration isolation pad 601, an outer housing 602 and friction balls 603. The vibration isolation pad 601 is fixed inside the outer pipe section 102. The outer housing 602 is fixed inside the vibration isolation pad 601. A plurality of friction balls 603 are movably installed inside the outer housing 602. The outer wall of the drainage pipe 2 is in sliding contact with the inner wall of the outer housing 602, so that the drainage pipe 2 can pass through the outer housing 602.
[0025] Working principle: When using this water supply and drainage pipe connection device, the drainage pipe 2 is passed through the sealing ring 302 and tightened into the inner pipe section 101 until the front end of the drainage pipe 2 abuts against the positioning retaining ring 103. Then, the sealing ring 302 is inserted into the outer pipe section 102, and the mounting ring 301 and the outer pipe section 102 are fixed together through bolts 4 and nuts 5. Since the outer diameter of the left end of the sealing ring 302 is smaller than the inner diameter of the outer pipe section 102, the sealing ring 302 can be inserted into the outer pipe section 102. And the outer diameter of the right end of the sealing ring 302 is larger than the inner diameter of the outer pipe section 102. After the sealing ring 302 is completely inserted into the outer pipe section 102, its right end is squeezed, so that the sealing ring 302 fits tightly with the drainage pipe 2, thereby improving the sealing performance and preventing water leakage. When the water flow impacts the drainage pipe 2, the drainage pipe 2 transmits the vibration to the outer housing 602, and the vibration is transmitted to a plurality of friction balls 603 through the outer housing 602, causing the plurality of friction balls 603 to rub against each other, thereby converting the vibration force into frictional force and consuming it. At the same time, the vibration is isolated to a certain extent by the vibration isolation pad 601, thereby reducing the vibration transmitted to the connector 1 and further improving the connection stability.
[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
