DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the following further elaborates in combination with specific implementation manners.

[0023] A water supply network leakage plugging device, see Figures 1 to 4The utility model provides a water leakage sealing device, including main sleeve 1, outer sleeve 7, no. 1 rubber block 5 and no. 2 rubber block 8, main sleeve 1 is made of two identical half ring sleeve, and the inner side wall of two main sleeve 1 is fixedly connected with no. 1 rubber block 5, the left end of main sleeve 1 is fixedly connected with annular lug 101, and the right end of main sleeve 1 is provided with annular groove 102, the surface of annular lug 101 away from main sleeve 1 is fixedly connected with rubber ring 6, and the outer surface of annular lug 101 and the outer surface of main sleeve 1 outside annular groove 102 are provided with a plurality of no. 1 bolt hole 4 in circumferential array, the annular lug 101 of new main sleeve 1 is inserted into the annular groove 102 of last main sleeve 1, and at this time rubber ring 6 can block the gap of the contact position of two main sleeve 1, thereby keeping sealed, so that multiple main sleeve 1 can be closely attached together to seal the longer water leakage gap, and the practicability of the device is improved.

[0024] The outer sleeve 7 is made of two identical half ring sleeves, and the inner side wall of the outer sleeve 7 is fixedly connected with the no. 2 rubber block 8, and the outer surface of the outer sleeve 7 is provided with a plurality of no. 2 bolt holes 9 in circumferential array on the left and right sides. After aligning the outer sleeve 7 with the outer walls of the left and right main sleeves 1, screws are inserted into the no. 1 bolt holes 4 and the no. 2 bolt holes 9, and are fixed between the outer surfaces of the left and right main sleeves 1. At this time, the no. 2 rubber block 8 will press and fit the annular lugs 101 and the annular grooves 102 on the left and right sides, blocking the gap. Therefore, when the pipe surface has sharp protrusions that are not easy to fit, the outer sleeve 7 can shield and seal the part of the water pipe, enriching the use scenarios and improving the practicability.

[0025] Specifically, as shown in Figure 1 and Figure 2 , the no. 1 bolt hole 4 passes through the outer surface of the main sleeve 1 and communicates with the annular groove 102. The no. 1 bolt hole 4 and the no. 2 bolt hole 9 are identical in size and number and correspond one-to-one. Therefore, by twisting the screw into the no. 2 bolt hole 9, the screw can pass through the no. 2 bolt hole 9 and enter the no. 1 bolt hole, thereby fixing the main sleeve 1 and the outer sleeve 7 together.

[0026] It is worth noting that, as shown in Figure 1 and Figure 2 , the upper and lower edges of the main sleeve 1 are fixedly connected with the fixed plates 2. The fixed plates 2 of the two main sleeves 1 are detachably connected by the fixed bolts 3. The fixed plates 2 are attached together and connected together by the fixed bolts 3, so that the two parts of the main sleeve 1 are attached and press the surface of the water pipe, allowing the no. 1 rubber block 5 to seal the water leakage.

[0027] It is worth noting that, as shown in Figure 3As shown, the upper and lower ends of the outer sleeve 7 are provided with a slot 701 and a fixedly connected plug 702, respectively, and when the two parts of the outer sleeve 7 are installed, the plug 702 of each part is inserted into the slot 701 after the two outer sleeves 7 are inverted relative to each other, thereby completing the limiting and cooperating with the screw of the second bolt hole 9 to fix the outer sleeve 7 to the outer surface of the main sleeve 1, thereby increasing the stability and ensuring the integrity of the sealing effect.

[0028] As shown in Figure 1 and Figure 4 , the outer sleeve 7 is located between the left and right main sleeves 1, and the left and right ends of the second rubber block 8 are located inside the annular groove 102 and are in extrusion fit with the rubber ring 6, respectively. When the outer sleeve 7 is installed, the two ends of the second rubber block 8 will be in close contact with the two sides of the main sleeve 1 during the extrusion process, thus plugging the gap, thereby avoiding water leakage.

[0029] As shown in Figure 1 and Figure 2 , the outer surface of the annular protrusion 101 is fixedly connected with a positioning block 103, and the inner wall of the annular groove 102 is provided with a positioning slot 104. When the main sleeve 1 needs to be extended, in order to quickly align, the positioning block 103 is aligned with the positioning slot 104 during insertion. At this time, after insertion, it will automatically align, allowing the left and right adjacent two main sleeves 1 to quickly align and avoiding relative rotation, thereby improving the efficiency of installation and plugging.

[0030] In actual use, the main sleeve 1 is fixed to the outer wall of the water pipe by tightening the fixing bolt 3 on the fixed plate 2, at which time the first rubber block 5 will extrude the water leakage position, and then the annular protrusion 101 of the new main sleeve 1 is inserted into the annular groove 102 of the previous main sleeve 1, at which time the rubber ring 6 will block the gap between the two main sleeves 1, thereby maintaining the seal, allowing multiple main sleeves 1 to be closely fitted together to plug the longer water leakage gap, thereby improving the practicality of the device. The size and number of the second bolt and the first bolt are consistent, and after aligning the outer wall of the left and right main sleeves 1, the screws are inserted into the first bolt hole 4 and the second bolt hole 9, thereby fixing them between the outer surfaces of the left and right two main sleeves 1. At this time, the second rubber block 8 will extrude and fit the annular protrusion 101 and the annular groove 102 on the left and right sides, thereby blocking the gap, so that the outer sleeve 7 can shield and plug the part of the water pipe when the surface of the pipe has a sharp protrusion that is not convenient to fit, thereby further improving the practicality of the device.

[0031] In addition, the components designed in the utility model are all general standard components or components known by the person skilled in the art, the structure and principle of which can be known by the person skilled in the art through a technical manual or through a conventional experimental method, and the person skilled in the art can completely realize without redundancy, and the content protected by the utility model does not involve improvement of internal structure and method.

[0032] The utility model discloses the preferable embodiment, but is not limited to this, and the person skilled in the art, very easily according to the above -mentioned embodiment, the spirit of the utility model is appreciated, and different extension and change are made, but as long as not departing from the spirit of the utility model, all are within the protection scope of the utility model.
