Description

Technical Field

[0001] The utility model relates to the technical field of leakage prevention, in particular to an injection-molded water inlet pipe joint leakage prevention device. Background Art

[0002] During the use of the washing machine, the injection molded water inlet pipe provides the washing machine with the required water. The water inlet pipe is usually made of plastic material. Although it has a certain strength, it may still break in some cases.

[0003] For example, in daily use, if the water inlet pipe is squeezed or pulled by external force, it may cause it to rupture. Especially during the installation or movement of the washing machine, if excessive physical damage is accidentally caused to the water inlet pipe, it is easy to cause the water inlet pipe to rupture;

[0004] During the operation of the washing machine, water leakage will not only cause a waste of water resources, but may also affect the normal use of the washing machine and increase maintenance costs. The existing injection-molded water inlet pipe has achieved a certain degree of anti-leakage effect by applying rubber sealing rings in multiple places. However, in actual application, the sealing effect of the sealing ring is not absolutely reliable. Due to the changes in water pressure in the water inlet pipe and the impact of water flow, the sealing ring may not always maintain a tight fit, resulting in tiny gaps and leakage. For example, when the washing machine is in strong washing mode, the water pressure in the water inlet pipe suddenly increases, and the sealing ring may be briefly flushed open, causing water to seep out from the gap. Utility Model Content

[0005] The utility model aims to provide an anti-leakage device for an injection-molded water inlet pipe joint to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molded water inlet pipe joint anti-leakage device, comprising an extension shell and a connector, wherein a plugging component is arranged on the extension shell;

[0007] The sealing assembly includes an inner shell, to which water-absorbing and swelling cotton is fixedly connected, to which a rotating shaft is fixedly connected, to which a transmission rod is rotatably connected, to which a sliding block is fixedly connected, to which a rubber seal is fixedly connected, and the rubber seal is slidably connected to the inner shell.

[0008] As a preferred implementation manner, the extension shell is fixedly connected to the connecting head, and a threaded groove is provided on the connecting head.

[0009] The above technical solution is adopted: by providing a threaded groove on the connecting head, the device can be installed on the water inlet pipe through the threaded groove by rotating the entire device during use, and then the device can be connected to the joint through the threaded groove in the extension shell at the other end.

[0010] As a preferred embodiment, the water-swellable cotton is slidably connected to the transmission rod, the rotating shaft is slidably connected to the transmission rod, and the rubber seal is slidably connected to a side of the inner shell close to the connector.

[0011] The above technical solution is adopted: by setting a water-absorbing and swelling cotton and a sliding connection with the transmission rod, when in use, when the inner shell ruptures and leaks water and penetrates into the interior of the extension shell, the side of the transmission rod away from the connecting head can be lifted up by the expansion of the water-absorbing and swelling cotton, so that it can rotate on the rotating shaft, so that the end of the transmission rod close to the connecting head slides inward, driving the sliding block and the rubber seal to slide inward, and the inner shell is blocked. The rubber seal usually has good elasticity and can fit tightly to the surface of the inner shell when contacting and sliding with the inner shell. Even in the sliding process, due to its elastic deformation ability, it can always maintain close contact with the inner shell, thereby preventing water leakage. For example, high-quality rubber materials can deform when subjected to a certain pressure, fill tiny gaps, and ensure sealing performance.

[0012] As a preferred implementation, a thread groove is provided inside the extension shell.

[0013] By adopting the above technical solution: by providing a thread groove inside the extension shell, when in use, the joint can be turned into the extension shell through the thread groove inside the extension shell, so that the joint is tightly connected with the inner shell.

[0014] As a preferred implementation, four transmission rods are provided, and the four transmission rods are all slidably connected to the transmission rod.

[0015] The above technical solution is adopted: by setting four transmission rods, when in use, the expansion of the water-absorbing and expandable cotton can drive one end of the transmission rod to rotate, so that the rubber seal slides in the inner shell, and the four rubber seals seal the inside of the inner shell, thereby stopping the water flow and avoiding further leakage and waste.

[0016] As a preferred implementation, the water-swellable cotton is slidably connected to an end of the transmission rod away from the sliding block.

[0017] The above technical solution is adopted: by arranging a water-absorbing and swelling cotton to be slidably connected to the end of the transmission rod away from the sliding block, when the inner shell leaks, the water-absorbing and swelling cotton quickly absorbs water and expands, driving one end of the transmission rod to tilt up, thereby realizing the transmission of the rubber seal, so that the rubber seal can seal the inner shell.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, when the inner shell is cracked and water seeps, the water-absorbing and swelling cotton in the device can quickly absorb water and swell, thereby triggering the subsequent blocking mechanism, and taking timely measures at the early stage of leakage to avoid continuous leakage of water, effectively saving resources, and preventing additional production costs due to leakage. Under the action of the water-absorbing and swelling cotton, the rubber seal can be driven to slide inward at the same time, so that the rubber seal is evenly stressed and the inside of the inner shell is more tightly blocked. The multi-directional sealing structure greatly improves the anti-leakage stability of the device. Even when the water pressure in the water inlet pipe suddenly increases, it will not be briefly opened like a traditional sealing ring. At the same time, the structural design of the device is relatively universal, and can adapt to various water inlet pipe sizes and industrial production scenarios, solving the problem that the prior art in the background technology only uses sealing rings for anti-seepage, and the anti-seepage effect is not ideal.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 4 As shown, an injection molded water inlet pipe joint anti-leakage device comprises an extension shell 1 and a connector 12, and a plugging component 2 is arranged on the extension shell 1;

[0029] The plugging assembly 2 includes an inner shell 23, to which a water-absorbing swelling cotton 26 is fixedly connected, to which a rotating shaft 21 is fixedly connected, to which a transmission rod 22 is rotatably connected, to which a sliding block 24 is fixedly connected, to which a rubber seal 25 is fixedly connected, and to which the rubber seal 25 is slidably connected.

[0030] In the utility model, when the inner shell 23 ruptures and leaks water, the water-absorbing and swellable cotton 26 in the device can quickly absorb water and swell, thereby triggering the subsequent blocking mechanism, and taking timely measures at the early stage of leakage to avoid continuous water leakage, effectively saving resources, and preventing additional production costs due to leakage. Under the action of the water-absorbing and swellable cotton 26, the rubber seal 25 can be driven to slide inward at the same time, so that the rubber seal 25 is evenly stressed and the inside of the inner shell 23 is more tightly blocked. The multi-directional sealing structure greatly improves the anti-leakage stability of the device. Even when the water pressure in the water inlet pipe suddenly increases, it will not be briefly opened like a traditional sealing ring. At the same time, the structural design of the device is relatively universal and can adapt to various water inlet pipe sizes and industrial production scenarios, solving the problem that the prior art in the background technology only uses sealing rings for anti-seepage and the anti-seepage effect is not ideal.

[0031] Further, such as Figures 1 to 4 As shown, the extension shell 1 is fixedly connected to the connector 12, and a thread groove is provided on the connector 12. By providing the thread groove on the connector 12, the device can be installed on the water inlet pipe by rotating the device as a whole during use through the thread groove, and then the device can be connected to the joint through the thread groove in the extension shell 1 at the other end;

[0032] The water-absorbing and swelling cotton 26 is slidably connected to the transmission rod 22, the rotating shaft 21 is slidably connected to the transmission rod 22, and the rubber seal 25 is slidably connected to the side of the inner shell 23 close to the connector 12. By setting the water-absorbing and swelling cotton 26 and the transmission rod 22 in a slidable connection, when in use, when the inner shell 23 is broken and water seeps into the interior of the extension shell 1, the expansion of the water-absorbing and swelling cotton 26 can lift up the side of the transmission rod 22 away from the connector 12, so that it can rotate on the rotating shaft 21, so that the end of the transmission rod 22 close to the connector 12 slides inward, driving the sliding block 24 and the rubber seal 25 to slide inward, and the inner shell 23 is blocked. The rubber seal 25 usually has good elasticity and can fit tightly to the surface of the inner shell 23 when contacting and sliding with the inner shell 23. Even in the sliding process, due to its elastic deformation ability, it can always maintain close contact with the inner shell 23, thereby preventing water leakage. For example, high-quality rubber materials can deform when subjected to a certain pressure to fill small gaps and ensure sealing performance.

[0033] A thread groove is provided inside the extension shell 1. By providing the thread groove inside the extension shell 1, when in use, the joint can be turned into the extension shell 1 through the thread groove inside the extension shell 1, so that the joint is tightly connected with the inner shell 23;

[0034] There are four transmission rods 22 in total, and the four transmission rods 22 are all slidably connected to the transmission rod 22. When in use, the expansion of the water-absorbing and swelling cotton 26 can drive one end of the transmission rod 22 to rotate, so that the rubber seal 25 slides in the inner shell 23. The four rubber seals 25 block the inside of the inner shell 23, thereby stopping the water flow and avoiding further leakage and waste.

[0035] The above solution also has the problem that the position of the water-absorbing and swelling cotton 26 is not specified, and the water-absorbing and swelling cotton 26 may cause the rubber seal 25 to expand outwards during use. Figure 4 As shown, the water-absorbing and swelling cotton 26 is slidably connected to the end of the transmission rod 22 away from the sliding block 24. By arranging the water-absorbing and swelling cotton 26 to be slidably connected to the end of the transmission rod 22 away from the sliding block 24, when the inner shell 23 leaks, the coefficient swelling cotton quickly absorbs water and expands, driving one end of the transmission rod 22 to tilt up, thereby realizing the transmission of the rubber seal 25, so that the rubber seal 25 blocks the inner shell 23.

[0036] Working principle: Figure 1 - Figure 4 As shown, a thread groove is provided on the connector 12, and the device can be installed on the water inlet pipe by rotating the device as a whole, and a thread groove is also provided inside the extension shell 1, and the connector can be turned into the extension shell 1 through the thread groove, so that the connector is tightly connected to the inner shell 23;

[0037] When the inner shell 23 ruptures and leaks water, and the water seeps into the interior of the extension shell 1, the water-absorbing and swelling cotton 26 quickly absorbs water and expands, lifting the side of the transmission rod 22 away from the connector 12, causing it to rotate on the shaft 21, thereby causing the transmission rod 22 to drive the sliding block 24 and the rubber seal 25 to slide on the inner shell 23. Since the rubber seal 25 has good elasticity, it can fit tightly to the surface of the inner shell 23 during the sliding process and will not leak water when sliding. The rubber seals 25 driven by the four transmission rods 22 block the inside of the inner shell 23, thereby stopping the water flow and avoiding further leakage and waste.

[0038] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
