Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal water supply pipe fixing structures, in particular to a municipal water supply pipe fixing structure. Background Art
[0002] Municipal water pipes are an important part of the urban water supply system. They are responsible for transporting clean drinking water from the water source to every corner of the city for residential, industrial and commercial use.
[0003] The construction of municipal water pipes needs to follow strict specifications and procedures, including trench excavation, pipeline installation, construction of ancillary facilities, functional testing, and maintenance and repair. During the construction process, special attention should be paid to the position, slope, and interface sealing of the pipeline to ensure the normal operation of the pipeline system. Municipal water pipes are made of a variety of materials, the most common of which are thin-walled stainless steel pipes, PPR pipes, copper pipes, aluminum-plastic pipes, and PVC pipes.
[0004] In the prior art, most of the current water supply pipes are prefabricated pipes. When laying, multiple pipes need to be connected to complete the laying of the entire water supply line. Then, when connecting the pipes, a connecting structure is required. In the prior art, two pipes are mostly connected by flange structure and threaded connection. However, the pipe connected by the flange structure is directly affected by the pressure of the soil at the connection between the two pipes when buried, which can easily lead to loosening of the bolts at the flange connection. The threaded connection will also cause changes in the thread gap due to uneven pressure at the threaded connection, causing water leakage. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a fixing structure for a municipal water supply pipeline so as to solve the technical problems mentioned in the above background technology.
[0006] The above technical objectives of the utility model are achieved through the following technical solutions:
[0007] A fixing structure for a municipal water supply pipeline comprises a pipeline base, positioning rings are arranged on both sides of the upper end of the pipeline base, a connecting outer pipe is arranged inside the two positioning rings, an annular platform is fixedly arranged inside the connecting outer pipe, a guide inner pipe is fixedly arranged inside the annular platform, sealing rings are filled in the gaps between the two ends of the guide inner pipe and the inner wall of the connecting outer pipe, and sealing rings are arranged at both ends of the inner part of the connecting outer pipe.
[0008] Furthermore, an inner groove is provided at the bottom end of the pipeline base, and both sides of the pipeline base are conical.
[0009] Furthermore, the outer walls at both ends of the guide inner tube are provided with external threads, and the spiral directions of the two sections of the external threads are the same.
[0010] Furthermore, the cross section of the sealing ring is U-shaped, the sealing ring is inserted in the gap between the guiding inner tube and the connecting outer tube, and the opening end of the U-shaped cross section of the sealing ring faces away from the annular platform.
[0011] Furthermore, the positioning ring is rotatably connected to the connecting outer tube, and a plurality of positioning holes are formed on the outer wall of the connecting outer tube.
[0012] Furthermore, the diameter of the inner wall of the connecting outer tube gradually increases from the position of the annular platform to the end.
[0013] Furthermore, a pressure dividing plate is commonly provided at the top ends of the two positioning rings.
[0014] In summary, the present invention includes at least one of the following beneficial technical effects:
[0015] 1. The fixing structure of a municipal water supply pipeline is used to support the connection of the pipeline through the pipeline base and the positioning ring. When the pipeline is buried, the positioning ring and the pipeline base can effectively support the soil or concrete buried on the upper part. The setting of the pressure dividing plate is used to increase the support area of the two positioning rings. When the pipeline is buried, the pressure of the soil on the pipeline is further reduced, so that the pressure of the soil is directly transmitted to the soil at the bottom of the municipal water pipe through the positioning ring and the pressure dividing plate, which can effectively prevent the connection of the municipal water pipe from being subjected to excessive pressure, thereby achieving the effect of increasing the service life of the municipal water pipe;
[0016] 2. The fixing structure of the municipal water supply pipe has both sides of the bottom end of the pipe base set in a conical shape. Therefore, when the pipe base is installed at the bottom of the pipe, both ends of the pipe base can be embedded in the soil, and the soil can be fixed inside the inner groove by setting the inner groove, which can effectively prevent the bottom of the pipe base from sinking and can effectively avoid the skewness of the pipe base, thereby improving the stability of the municipal water pipe;
[0017] 3. This is a fixing structure for a municipal water supply pipe. When the municipal water pipe is connected to the connecting outer pipe and the guiding inner pipe, the outer walls of the municipal water pipe and the guiding inner pipe are connected to each other through external threads and internal threads, and the sealing ring will be squeezed when the threads between the external threads and the internal threads are matched, so that the sealing ring is in close contact with the municipal water pipe and the guiding inner pipe, thereby effectively avoiding the problem of water leakage at the contact position between the municipal water pipe and the guiding inner pipe.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0026] Example:
[0027] Reference Figure 1-Figure 5 The utility model discloses a fixing structure of a municipal water supply pipeline, comprising a pipeline base 1, positioning rings 2 are arranged on both sides of the upper end of the pipeline base 1, a connecting outer pipe 3 is arranged inside the two positioning rings 2, an annular platform 4 is fixedly arranged inside the connecting outer pipe 3, a guiding inner pipe 5 is fixedly arranged inside the annular platform 4, the gaps between the two ends of the guiding inner pipe 5 and the inner wall of the connecting outer pipe 3 are filled with sealing rings 6, and sealing rings 7 are arranged at both ends of the inner part of the connecting outer pipe 3.
[0028] In this embodiment, the pipe base 1 and the positioning ring 2 are used to install the connecting outer pipe 3. When laying the pipe, the connecting outer pipe 3 and the guiding inner pipe 5 are used to fix two municipal pipes. After the pipe is installed, the two positioning rings 2 are used to connect the connecting outer pipe 3 and the pipe base 1 to each other, so that the pipe base 1 and the positioning ring 2 are used to support the connection of the pipe. When the pipe is buried, the positioning ring 2 and the pipe base 1 can effectively support the soil or concrete buried on the upper part, which can effectively avoid the problem of fracture at the connection due to pressure on the pipe, thereby achieving the effect of protecting the pipe.
[0029] Specifically, when installing two municipal water pipes, firstly, one end of the connecting outer pipe 3 and the guiding inner pipe 5 is aligned with one end of the municipal water pipe, and then the open end of the sealing ring 6 is sleeved on one end of the municipal water pipe, such as Figure 5 As shown, in Figure 5 In the figure, A is a municipal water pipe. After the sealing ring 6 is sleeved on one end of the municipal water pipe, the connecting outer pipe 3 is inserted into the other end of the municipal water pipe so that the sealing ring 6 is inserted into the position corresponding to the outer wall of the guiding inner pipe 5 and the inner wall of the connecting outer pipe 3. At this time, the outer wall of the sealing ring 6 is in contact with the outer wall of the guiding inner pipe 5, the inner wall of the connecting outer pipe 3 and the side wall of the annular platform 4 respectively, so that the contact positions of the municipal water pipe and the guiding inner pipe 5, the connecting outer pipe 3 and the annular platform 4 are in close contact under the influence of the sealing ring 6. At this time, the tightness of the connection between the two municipal pipelines can be effectively improved.
[0030] In a further preferred embodiment of the present invention, Figure 1-5 As shown, an inner groove 8 is provided at the bottom end of the pipe base 1, and both sides of the pipe base 1 are conical.
[0031] In this embodiment, since both sides of the bottom end of the pipe base 1 are tapered, when the pipe base 1 is installed at the bottom of the pipe, both ends of the pipe base 1 can be embedded in the soil, and the soil can be fixed inside the inner groove 8 by setting the inner groove 8, which can effectively prevent the bottom of the pipe base 1 from sinking and can effectively avoid the skewing of the pipe base 1, thereby improving the stability of the municipal water pipe.
[0032] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the outer walls at both ends of the guide inner tube 5 are provided with external threads 9, and the spiral directions of the two sections of the external threads 9 are the same.
[0033] In this embodiment, through the external threads 9 provided on both sides of the outer wall of the guide inner tube 5, when the guide inner tube 5 and the connecting outer tube 3 are connected to the municipal water pipe, the guide inner tube 5 can be effectively screwed into the interior of the municipal water pipe by rotating the connecting outer tube 3, and the inner wall of the municipal water pipe is provided with an internal thread matching the external thread 9 to achieve the purpose of fixing the municipal water pipe and the guide inner tube 5. When installing another municipal water pipe, the water pipe is aligned with the guide inner tube 5 and the connecting outer tube 3, and the water pipe is rotated to gradually screw in, so that the water pipe and the guide inner tube 5 and the connecting outer tube 3 contact each other, thereby achieving the purpose of connecting the two water pipes to the guide inner tube 5 and the connecting outer tube 3. Moreover, since the thread directions of the two external threads 9 are the same, when the water pipe is rotated, the water pipe that has been installed will not loosen due to rotation.
[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the cross section of the sealing ring 6 is U-shaped, and the sealing ring 6 is inserted into the gap between the guiding inner tube 5 and the connecting outer tube 3 , and the opening end of the U-shaped cross section of the sealing ring 6 faces away from the annular platform 4 .
[0035] In the present embodiment, since the cross-section of the sealing ring 6 is U-shaped, and when the sealing ring 6 is connected to the municipal water pipe, the open end of the U-shaped cross-section corresponds to the end of the municipal water pipe, the sealing ring 6 can be sleeved on the end of the municipal water pipe, and when the municipal water pipe is connected to the connecting outer pipe 3 and the guide inner pipe 5, the outer walls of the municipal water pipe and the guide inner pipe 5 are connected to each other through the external thread 9 and the internal thread, and when the threads between the external thread 9 and the internal thread are matched, the sealing ring 6 will be squeezed, so that the sealing ring 6 is in close contact with the municipal water pipe and the guide inner pipe 5, thereby effectively avoiding the problem of water leakage at the contact position between the municipal water pipe and the guide inner pipe 5.
[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the positioning ring 2 is rotatably connected to the connecting outer tube 3 , and a plurality of positioning holes 10 are formed on the outer wall of the connecting outer tube 3 .
[0037] In the present embodiment, since the positioning ring 2 is rotatably connected to the connecting outer tube 3, and since the water pipes are connected in sequence, and the municipal water pipe connected to the water outlet cannot be rotated, the positioning ring 2 and the connecting outer tube 3 are rotatably connected. When the connecting outer tube 3 is installed on one side of the municipal water pipe, the connecting outer tube 3 can be rotated to fix the connecting outer tube 3 and the municipal water pipe. Moreover, the positioning hole 10 can be used to insert a rod-shaped object such as a crowbar to rotate the connecting outer tube 3, so as to facilitate the tight connection between the connecting outer tube 3 and the municipal water pipe. When another municipal water pipe is installed on the other side of the connecting outer tube 3, the municipal water pipe can be rotated to achieve the effect of fixed connection with the connecting outer tube 3.
[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the inner wall diameter of the connecting outer tube 3 gradually increases from the position of the annular platform 4 to the end.
[0039] In this embodiment, since the inner wall diameter of the connecting outer tube 3 gradually increases from the inside to the two ends, the pressure on the sealing ring 6 will gradually increase during the process of inserting the municipal water pipe into the interior of the connecting outer tube 3. Since the movement direction of the gas is from high pressure to low pressure, the gas inside the sealing ring 6 can be effectively squeezed out when the municipal water pipe is inserted, so as to prevent the appearance of air at the connection between the connecting outer tube 3 and the municipal water pipe, resulting in reduced sealing.
[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a pressure dividing plate 11 is commonly provided at the top ends of the two positioning rings 2 .
[0041] In this embodiment, the pressure dividing plate 11 is provided to increase the support area of the two positioning rings 2. When burying the pipeline, the pressure of the soil on the pipeline is further reduced, so that the pressure of the soil is directly transmitted to the soil at the bottom of the municipal water pipe through the positioning ring 2 and the pressure dividing plate 11, which can effectively prevent the connection of the municipal water pipe from being subjected to excessive pressure, thereby achieving the effect of increasing the service life of the municipal water pipe.
[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
