[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a municipal water supply pipeline sealing structure, comprising:

[0005] A water baffle, wherein a ring sleeve is coaxially provided on one side of the water baffle;

[0006] A sealing ring is fitted onto the outside of the annular sleeve and abuts against the water baffle.

[0007] An extrusion plate is slidably disposed on the outside of the annular sleeve along the axial direction of the annular sleeve, and the sealing ring is located between the extrusion plate and the baffle plate;

[0008] A pushing component is used to push the extrusion plate toward the direction of the baffle plate;

[0009] The positioning rods are arranged at even intervals along the circumference of the annular sleeve, and their length direction is arranged along the radial direction of the annular sleeve. The positioning rods are threadedly connected to the side wall of the annular sleeve.

[0014] In one possible implementation, the sliding plate includes a plurality of connecting arms arranged radially along the annular sleeve, and the abutting portion is mounted on the connecting arms.

[0015] In one possible implementation, the inner side of the contact portion is an arc-shaped surface that slides in conjunction with the outer wall of the annular sleeve.

[0016] In one possible implementation, the sidewall of the annular sleeve is provided with a clearance groove for avoiding the connecting arm, and the connecting arm is located inside the clearance groove.

[0017] In one possible implementation, a U-shaped component is fixedly installed on the inner wall of the annular sleeve, and a connector for installing the positioning rod is fixedly installed on the U-shaped component. The positioning rod is threadedly connected to the connector, and the positioning rod passes through the side wall of the U-shaped component and the annular sleeve.

[0018] In one possible implementation, a plurality of positioning rods are also installed on the sidewall of the annular sleeve, the plurality of positioning rods being evenly spaced along the circumference of the annular sleeve, and the positioning rods extending outward from the outer side of the annular sleeve.

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Please refer to the following: Figure 1 and Figure 2 The municipal water supply pipeline sealing structure provided by this utility model is described below. The municipal water supply pipeline sealing structure includes a baffle plate 1, a sealing ring 3, a pressing plate 4, a pushing assembly 5, and positioning rods 6. An annular sleeve 2 is coaxially arranged on one side of the baffle plate 1; the sealing ring 3 is fitted onto the outer side of the annular sleeve 2 and abuts against the baffle plate 1; the pressing plate 4 is slidably disposed on the outer side of the annular sleeve 2 along its axial direction, and the sealing ring 3 is located between the pressing plate 4 and the baffle plate 1; the pushing assembly 5 is used to push the pressing plate 4 towards the baffle plate 1; there are multiple positioning rods 6, which are evenly spaced along the circumference of the annular sleeve 2, and the length direction of the positioning rods 6 is arranged radially along the annular sleeve 2, and the positioning rods 6 are threadedly connected to the side wall of the annular sleeve 2.

[0028] The municipal water supply pipeline sealing structure provided in this embodiment, compared with the prior art, features a baffle plate 1, which is a circular structure smaller than the inner diameter of the pipe. An annular sleeve 2 is fixedly installed on one side of the baffle plate 1, and the annular sleeve 2 is coaxially arranged with the baffle plate 1. A sealing ring 3 is fitted on the outer side of the annular sleeve 2, with the inner ring of the sealing ring 3 abutting against the outer wall of the annular sleeve 2, and the sealing ring 3 is located between the baffle plate 1 and the compression plate 4. In this application, when sealing the pipe port, the baffle plate 1 can be first placed inside the pipe port. By rotating the positioning rod 6, the relative positions of multiple positioning rods 6 are adjusted, causing them to abut against the inner wall of the pipe to fix the annular sleeve 2 and the baffle plate 1 inside the pipe. Then, the pushing component 5 pushes the compression plate 4 to move, squeezing the sealing ring 3 between the baffle plate 1 and the compression plate 4. The sealing ring 3 deforms and abuts against the inner wall of the pipe, thus sealing the pipe port. When removal is required, simply loosen the pushing component 5 and the positioning rod 6 to remove the baffle 1 from inside the pipe. The operation is simple, and sealing and disassembly are convenient.

[0029] Specifically, in this embodiment, the positioning rod 6 is a bolt.

[0030] In some embodiments, the aforementioned actuating component 5 may employ, for example... Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 The pushing assembly 5 includes a fixed rod 51, a sliding plate 52, and a pushing member 53. The fixed rod 51 is fixedly mounted on the baffle plate 1, and its length direction is perpendicular to the baffle plate 1. The sliding plate 52 is slidably mounted on the fixed rod 51, and the sliding plate 52 is provided with a contact portion 522 for abutting against the extrusion plate 4. The pushing member 53 is threadedly connected to the fixed rod 51 and can abut against the side of the sliding plate 52. The sliding plate 52 is coaxially mounted with the fixed rod 51, and a sleeve that is slidably mounted on the fixed rod 51 is fixedly mounted in the middle of the sliding plate 52, thereby enhancing the stability of the sliding plate 52 sliding on the fixed rod 51. The contact portion 522 is provided on the outer side of the sliding plate 52 in the direction close to the extrusion plate 4. When the sliding plate 52 slides in the direction close to the extrusion plate 4, multiple contact portions 522 abut against the extrusion plate 4 at the same time, and push the extrusion plate 4 to move in the direction close to the sealing ring 3. The pusher 53 is a nut, which is threadedly connected to the fixed rod 51. The pusher 53 abuts against the side of the sliding plate 52 away from the pressing plate 4, so that the pusher 53 can be rotated to drive the sliding plate 52 to move.

[0031] In some embodiments, the sliding plate 52 may be adopted as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2The sliding plate 52 includes a plurality of connecting arms 521 arranged radially along the annular sleeve 2, and abutting portions 522 are mounted on the connecting arms 521. The sliding plate 52 includes a plurality of fixedly connected connecting arms 521, which are evenly spaced along the circumference of the fixed rod 51, and the ends of the plurality of connecting arms 521 extend out of the outer side of the annular sleeve 2. The abutting portions 522 are mounted on the ends of the connecting arms 521. When the plurality of connecting arms 521 move toward the extrusion plate 4, the abutting portions 522 can abut against the extrusion plate 4, thereby pushing the extrusion plate 4 to move.

[0032] Specifically, in this embodiment, the arrangement of multiple connecting arms 521 reduces the overall weight of the sliding plate 52, facilitating installation by on-site operators. Simultaneously, the positioning rod 6 is located between two adjacent connecting arms 521, providing sufficient operating space between the two connecting arms 521 for manipulating the positioning rod 6.

[0033] Preferably, in this embodiment, a reinforcing rib is provided at the bottom of the connecting arm 521 to enhance the strength of the connecting arm 521, and a support sleeve is fixedly installed at the connection of multiple connecting arms 521. The support sleeve is slidably disposed on the fixed rod 51, and the reinforcing rib is fixedly installed between the support sleeve and the connecting arm 521.

[0034] In some embodiments, the aforementioned contact portion 522 may be as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 The inner side of the contact portion 522 is an arc-shaped surface that slides in conjunction with the outer wall of the annular sleeve 2. The contact portion 522 is slidably disposed on the outer wall of the annular sleeve 2. Through the sliding engagement between the contact portion 522 and the annular sleeve 2, the position of the sliding plate 52 can be guided, thereby improving the stability of the sliding plate 52's position. Simultaneously, the annular sleeve 2 can support the contact portion 522, preventing it from deforming or bending when pressed against the compression plate 4.

[0035] In some embodiments, the aforementioned annular sleeve 2 can be adopted as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 The annular sleeve 2 has a clearance groove on its side wall to allow the connecting arm 521 to pass. The connecting arm 521 is located inside the clearance groove. Multiple clearance grooves are provided at the end of the annular sleeve 2 away from the baffle plate 1, and these grooves are evenly spaced along the circumference of the annular sleeve 2. The connecting arm 521 is installed inside the clearance groove. This saves installation space between the connecting arm 521 and the annular sleeve 2. Simultaneously, the clearance groove limits the movement of the sliding plate 52 on the fixed rod 51, preventing the sliding plate 52 from rotating with the pushing member 53 when it is rotated, thus avoiding interference with on-site operation.

[0036] In some embodiments, the aforementioned annular sleeve 2 can be adopted as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 A U-shaped component 61 is fixedly installed on the inner wall of the annular sleeve 2. A connecting component 62 for installing the positioning rod 6 is fixedly installed on the U-shaped component 61. The positioning rod 6 is threadedly connected to the connecting component 62 and passes through the U-shaped component 61 and the side wall of the annular sleeve 2. The U-shaped component 61 is made of channel steel, and the two legs of the channel steel are fixedly installed on the inner wall of the annular sleeve 2 by welding. The connecting component 62 is fixedly installed on the waist of the channel steel by welding, and a clearance hole for avoiding the positioning rod 6 is provided on the waist of the channel steel. A clearance hole for avoiding the positioning rod 6 is provided on the side wall of the annular sleeve 2. The two clearance holes are spaced apart along the axis of the positioning rod 6, which can play a certain guiding role in the installation of the positioning rod 6. The structure is simple and facilitates the installation of the connecting component 62.

[0037] Specifically, in this embodiment, the connector 62 is a nut. The connector 62 can be welded to the U-shaped part 61 first, and then the U-shaped part 61 can be welded to the inner wall of the annular sleeve 2. This completes the installation of the connector 62 on the annular sleeve 2.

[0038] In some embodiments, the aforementioned annular sleeve 2 can be adopted as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 Multiple guide rods 7 are also installed on the side wall of the annular sleeve 2. These guide rods 7 are evenly spaced along the circumference of the annular sleeve 2 and extend beyond the outer side of the annular sleeve 2. When the baffle plate 1 is placed inside the pipe, the outer surfaces of the guide rods 7 abut against the end of the pipe to position the annular sleeve 2, thereby positioning the baffle plate 1. This prevents the baffle plate from tilting and affecting the sealing effect.

[0039] In some embodiments, the guide rod 7 described above can be as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2The guide rod 7 has two threaded fasteners 71, located on opposite sides of the side wall of the annular sleeve 2. The guide rod 7 passes through the side wall of the annular sleeve 2, and the two fasteners 71 are threaded onto it; each fastener 71 is a nut. The two fasteners 71 secure the guide rod 7 to the side wall of the annular sleeve 2. The position of the guide rod 7 on the annular sleeve 2 is adjusted by changing the position of the two fasteners 71, allowing the guide rod 7 to abut against the end of the pipe.

[0040] In some embodiments, the guide rod 7 described above can be as follows: Figure 1 ,like Figure 2 The structure shown. See also... Figure 1 , Figure 2 The guide rod 7 has a guide portion 72 at its center, with an outer diameter larger than that of the guide rod 7. The guide portion 72 is coaxially arranged with the guide rod 7. When the guide rod 7 abuts against the end of the pipe, the guide portion 72 on the guide rod 7 abuts against the end of the pipe. Because the outer side of the guide rod 7 has a threaded portion that is threaded to the fixing member 71, and the guide portion 72 is provided, the threaded portion can be prevented from abutting against the end of the pipe, thus avoiding damage to the threads on the outer side of the guide rod 7. This prevents thread damage from affecting the normal use of the guide rod 7.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
