Description

Technical Field

[0001] This utility model belongs to the field of municipal facility connection technology, and in particular relates to a quick docking connection structure for municipal drainage pipe networks. Background Technology

[0002] In the construction and maintenance of municipal drainage pipe networks, rapid and efficient pipe connection is a key link to ensure construction progress and project quality. Traditional pipe connection methods mostly use flange connection or welding process. Flange connection requires precise alignment of multiple bolt holes and tightening of bolts one by one, which is not only time-consuming and labor-intensive, but also prone to bolt corrosion in underground damp and confined working environments, leading to difficulties in subsequent maintenance. Welding process requires a high level of technical skills from construction personnel, and the welding quality is greatly affected by factors such as ambient temperature and humidity. In addition, the sparks generated during welding may cause safety hazards. Furthermore, the welded pipe joints are difficult to disassemble, which brings great inconvenience to later pipe inspection and replacement.

[0003] With the acceleration of urbanization, the number of municipal drainage pipe network laying and renovation projects is increasing, and the requirements for pipe connection efficiency and reliability are also constantly increasing. Although some existing quick connection structures have simplified the operation process to a certain extent, there are still problems such as insufficient connection accuracy, poor sealing performance or insufficient connection strength, which make it difficult to meet the drainage needs of complex municipal environments.

[0004] The invention patent with publication number CN219866750U discloses a pipe connection device for municipal water supply and drainage. This device uses a snap ring with its front end tilted so that one end of the pipe body presses against the snap ring and enters a circular groove. The snap ring compresses a spring. When a second circular groove on one end of the pipe body aligns with the first circular groove, the snap ring, under the action of the spring, enters the second circular groove, thus completing the connection between the pipe body and the snap ring. While this method appears simple and quick in operation, it reveals many problems in practical applications. The connection between pipes using this device is not very tight, and leaks easily occur at the pipe joints under high water pressure, failing to effectively guarantee the stability and sealing of drainage. Furthermore, its installation is not convenient, and the installation speed cannot meet the pace of rapid construction in large-scale municipal projects. In complex construction environments, such as narrow underground passages or densely populated areas, its low installation efficiency is even more pronounced.

[0005] Therefore, it is necessary to provide a new quick-connection structure for municipal drainage pipe networks to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a quick docking connection structure for municipal drainage pipe networks that uses the meshing transmission of a rotating ring and gears and threaded connection to achieve synchronous fastening of multiple sleeves and T-shaped rods. Therefore, it is not necessary to operate the connecting parts one by one, which can greatly shorten the docking time. At the same time, the tight fit between the insert ring and the sealing ring can ensure the sealing performance of the pipe connection.

[0007] To solve the above-mentioned technical problems, the municipal drainage network pipeline quick docking connection structure provided by this utility model includes: pipeline one, pipeline two and connection mechanism. Pipeline one and pipeline two are docked through the connection mechanism. The connection mechanism includes a first fixed collar, a second fixed collar, multiple T-shaped rods, a sliding collar and multiple sleeves.

[0008] The first and second fixed collars are respectively fixedly sleeved on the ends of pipe one and pipe two that are close to each other. Multiple T-shaped rods are installed in a ring array on the first fixed collar. The second fixed collar has multiple through holes, each of which corresponds to one of the multiple T-shaped rods. One end of each T-shaped rod passes through a through hole and is slidably connected to the through hole.

[0009] The sliding collar is slidably sleeved on the second pipe. Multiple sleeves are installed on the sliding collar in a ring array. Each sleeve corresponds to a multiple T-shaped rod. The inner wall of the sleeve near the second fixed collar is provided with an internal thread. The end of the T-shaped rod away from the first fixed collar is provided with an external thread. The external thread on one end of the T-shaped rod is screwed into the internal thread on one end of the sleeve.

[0010] As a further embodiment of this utility model, the connecting mechanism further includes a rotating ring, which is rotatably sleeved on the outer wall of the sliding collar.

[0011] As a further embodiment of this utility model, the connecting mechanism also includes a plurality of gears, which are respectively fixedly sleeved on the ends of the plurality of sleeves away from the fixed collar.

[0012] As a further embodiment of this utility model, the length of the rotating ring is greater than the length of the sliding collar, and the inner wall of the rotating ring is equipped with multiple teeth, which mesh with multiple gears.

[0013] As a further embodiment of this invention, the outer wall of the rotating ring is equipped with a plurality of friction blocks.

[0014] As a further embodiment of this utility model, a plug ring is installed at one end of the first pipe near the second pipe, and a sealing groove is opened at one end of the second pipe near the first pipe. A sealing ring is installed in the sealing groove, and one end of the plug ring is adapted to the sealing groove and the sealing ring.

[0015] Compared with related technologies, the quick-connection structure for municipal drainage pipe networks provided by this utility model has the following advantages:

[0016] 1. This utility model can achieve synchronous fastening of multiple sleeves and T-shaped rods through the meshing transmission of rotating ring and gear and threaded connection. Therefore, it is not necessary to operate the connecting parts one by one, which can greatly shorten the docking time. It is especially suitable for underground narrow space operations and reduces the labor intensity of construction workers.

[0017] 2. This utility model forms multiple symmetrically distributed mechanical connection points with the fixing collar one, fixing collar two, T-shaped rod, and sleeve, which disperses the axial and radial forces during pipeline operation, improves the overall connection strength, and effectively resists the loosening of the interface caused by water flow impact or soil pressure.

[0018] 3. This utility model ensures the sealing performance of the pipe connection through the tight fit between the insert ring and the sealing ring. Attached Figure Description

Figure 1 ; Figure 2 This is a three-dimensional illustration of the present invention. Figure 2 ; Figure 3 for Figure 2 A magnified structural diagram of part A in the middle; Figure 4 This is a cross-sectional structural diagram of the present invention; Figure 5 This is a schematic diagram of pipe separation in this utility model. The quick-connection structure for municipal drainage network pipes includes: pipe one 1, pipe two 2, and a connecting mechanism. Pipe one 1 and pipe two 2 are connected through the connecting mechanism, which includes a first fixed collar 3, a second fixed collar 4, multiple T-shaped rods 5, a sliding collar 6, and multiple sleeves 7.

[0027] The first fixed collar 3 and the second fixed collar 4 are respectively fixedly sleeved on the close ends of the first pipe 1 and the second pipe 2. Multiple T-shaped rods 5 are installed in a ring array on the first fixed collar 3. The second fixed collar 4 has multiple through holes, which correspond one-to-one with multiple T-shaped rods 5. One end of the T-shaped rod 5 passes through the through hole and is slidably connected to the through hole.

[0028] The sliding collar 6 is slidably sleeved on the pipe 2. Multiple sleeves 7 are installed on the sliding collar 6 in a ring array. Each sleeve 7 corresponds to a multiple T-shaped rod 5. The inner wall of the sleeve 7 near the fixed collar 4 is provided with an internal thread. The end of the T-shaped rod 5 away from the fixed collar 3 is provided with an external thread. The external thread on one end of the T-shaped rod 5 is screwed into the internal thread on one end of the sleeve 7.

[0029] The connecting mechanism also includes a rotating ring 8, which is rotatably sleeved on the outer wall of the sliding collar 6.

[0030] The connecting mechanism also includes a plurality of gears 9, which are respectively fixedly sleeved on the ends of the plurality of sleeves 7 away from the fixed collar 4.

[0031] The length of the rotating ring 8 is greater than the length of the sliding collar 6. The inner wall of the rotating ring 8 is equipped with a plurality of teeth 10, which mesh with a plurality of gears 9.

[0032] The outer wall of the rotating ring 8 is equipped with a plurality of friction blocks 11.

[0033] A plug ring 12 is installed at one end of the pipe 1 near the other end of the pipe 2. A sealing groove is opened at one end of the pipe 2 near the first pipe. A sealing ring 13 is installed in the sealing groove. One end of the plug ring 12 is adapted to the sealing groove and the sealing ring 13.

[0034] The working principle of the quick-connection structure for municipal drainage pipe networks provided by this utility model is as follows:

[0035] First step: Push pipe 1 and pipe 2 closer to each other so that T-shaped rod 5 passes through the corresponding through hole. At the same time, the insertion ring 12 at the end of pipe 1 is inserted into the sealing groove of pipe 2 and fits with the sealing ring 13 to achieve pipe positioning and sealing.

[0036] The second step: The sliding collar 6 slides on pipe 2, aligning the sleeve 7 with the corresponding T-shaped rod 5 and initially inserting the T-shaped rod 5 into the corresponding sleeve 7. Then, the rotating ring 8 is rotated, and the teeth 10 on its inner wall mesh with the gear 9, thereby driving multiple sleeves 7 to rotate synchronously. Since the internal thread on the inner wall of the sleeve 7 is screwed into the external thread at the end of the T-shaped rod 5, the sleeve 7 will move along the axial direction of the T-shaped rod 5 during rotation, gradually closing the distance between the fixed collar 3 and the fixed collar 4 until the docking ends of pipe 1 and pipe 2 are tightly fitted, completing the fastening connection. As the fixed collar 3 and the fixed collar 4 approach each other, the insertion ring 12 further squeezes the sealing ring 13 to ensure the sealing effect of the pipe connection.
