Description

Technical Field

[0001] The utility model belongs to the technical field of dredges, in particular to a plugging device for dredges and a plugging connecting pipe. Background Art

[0002] Clogged drains and toilets are common everyday problems, and plumbers can help solve this problem. Existing plumbers, such as the pneumatic toilet dredge proposed in prior patent CN218881073U, typically pump air into a gas storage device to generate energy. The gas is then released from a plug mounted at the outlet. This powerful gas flow unclogs the clogged drain or toilet.

[0003] At present, the connection structure of most flushing tools and plugging devices is complicated during the connection process. For example, a flexible toilet flushing head proposed in CN219471116 U has a first connecting component and a second connecting component respectively connected to the flushing tool air storage device and the air bag. The first connecting component and the second connecting component each include multiple components. The multiple components are connected together, which is not only complex in structure and not convenient to install, but also more likely to fail. Summary of the Invention

[0031] <Example 1>

[0032] This embodiment proposes a plugging device 5 for a dredge, such as Figure 1 and Figure 2 As shown, the plug device 5 includes: a plug connecting pipe 50, a bladder 54, a nut 55 and a washer 56. The plug connecting pipe 50 is used to connect the gas outlet end of the gas storage device and the bladder 54, as shown in FIG. Figure 3 As shown, the plug connection pipe 50 includes an air inlet connection portion 51, a flexible tube portion 52, and a bladder mounting portion 53. The air inlet connection portion 51 is used to connect to the air outlet end of the air storage device, which has an external thread structure. The bladder mounting portion 53 is used to mount the bladder mounting end 541 of the bladder 54. The flexible tube portion 52 connects the air inlet connection portion 51 and the bladder mounting portion 53. The flexible tube portion 52 is relatively soft and can deform and bend under external force to adapt to different pipe shapes to be cleared. A nut 55 is mounted on the outside of the bladder mounting portion 53 to secure the bladder 54 to the bladder mounting portion 53. A washer 56 is placed between the bladder 54 and the nut 55.

[0033] The air inlet connecting portion 51, the flexible tube portion 52 and the bladder mounting portion 53 are integrally formed, and an exhaust passage 57 is provided inside. The bladder 54 is hollow and has a bladder mounting end 541 with a mounting hole and a bladder air outlet end 542. The bladder mounting end 541 is mounted on the bladder mounting portion 53, and the bladder air outlet end 542 is provided with an air outlet 5421. The gas from the air outlet end of the gas storage device enters the bladder 54 through the exhaust passage 57 and is finally discharged from the air outlet of the bladder 54.

[0034] Specifically, the bladder mounting portion 53 includes an inner wall abutting section 531 and a threaded fixing section 532. The inner wall abutting section 531 is used to abut against the inner wall of the bladder mounting end 541, and the threaded fixing section 532 is used to install the nut 55. The inner wall abutting section 531 is an annular convex ring or a plurality of convex blocks distributed circumferentially, such as Figure 4As shown, the annular protrusion cooperates with the nut 55 to position the bladder mounting end 541 therebetween. The bladder mounting portion 53 also includes a bladder support segment 534, located on the side of the inner wall abutment segment 531 away from the threaded fixing segment 532. Several reinforcing ribs 535 are circumferentially disposed on the bladder support segment 534, connecting to the inner wall abutment segment 531. The bladder support segment 534 is hollow and cylindrical, inserted into the bladder 54, providing support for the bladder 54 and preventing it from being crushed and malfunctioning.

[0035] like Figure 4 As shown, the outer diameter D1 of the air intake connection part 51 is less than the outer diameter D2 of the threaded fixing section 532 and less than the outer diameter D3 of the inner wall abutting section 531. Since D1 is less than D2 and less than D3, during installation, the nut 55 passes through the end where the air intake connection part 51 is located, and is inserted into the threaded fixing section 532 along the flexible tube part 52 for fixing, and the bladder 54 is fixed on the inner wall abutting section 531.

[0036] The inner side of the air inlet connection part 51 is provided with an internal thread 513 for fixed connection with the air outlet end of the air storage device, and the outer side is provided with a clamping structure. The clamping structure can be a polygonal tool clamping structure or a plurality of anti-slip ribs 514. In this embodiment, the anti-slip ribs 514 are preferably provided, which are convenient for the user to hold the air inlet connection part 51 and rotate the plug device 5 to fix the plug device 5 to the air outlet end of the air storage device.

[0037] An inner convex ring 511 protruding toward the other end is also provided inside the end where the air intake connection part 51 is connected to the flexible tube part 52, and a receiving groove 512 is formed between the inner convex ring 511 and the side wall of the air intake connection part 51. The receiving groove 512 can be used for the port of the air outlet end of the air storage device to be inserted, so that the inner convex ring 511 is embedded in the air outlet end. On the one hand, it can strengthen the connection between the air intake connection part 51 and the air outlet end of the air storage device, and on the other hand, it can also strengthen the sealing between the two.

[0038] The air intake connection part 51, the flexible tube part 52 and the bladder mounting part 53 are all injection molded by flexible materials. The flexible material can be rubber or plastic, preferably PP material. The PP material has certain strength and flexibility. Its flexibility can ensure that the flexible tube part 52 can bend and deform, and adapt to different shapes of pipelines to be cleared. Its strength can ensure the connection reliability of the air intake connection part 51 and the bladder mounting part 53.

[0039] like Figure 4 As shown, the bladder mounting end 541 extends outward (ie, toward the end where the flexible tube portion 52 is located) with a mounting protruding ring 543, and the washer 56 is sleeved on the outer periphery of the mounting protruding ring 543. Figure 5 and Figure 6As shown, a plurality of stop protrusions 561 are provided on the side of the washer 56 close to the nut 55, and a plurality of stop grooves 551 are correspondingly provided on the nut 55. When the nut 55 is installed on the threaded fixing section 532, the stop protrusions 561 are inserted into the stop grooves 551, thereby strengthening the connection between the nut 55 and the washer 56, and being able to firmly fit the washer 56 on the bladder mounting end 541.

[0040] <Example 2>

[0041] In this embodiment, based on the above-mentioned embodiment 1, a spring 58 is additionally provided in the exhaust passage 57 inside the flexible tube portion 52 to facilitate the flexible tube portion 52 to return to its original state.

[0042] <Example 3>

[0043] In this embodiment, based on the above embodiments, the air intake connection part 51 and the bladder mounting part 53 are made of hard materials and are secondary injection molded with the flexible tube part 52. This can further improve the connection reliability of the air intake connection part 51 and the bladder mounting part 53, especially ensure the size of the internal thread 513 of the air intake connection part 51, thereby improving the sealing of the connection.

[0044] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
