Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a leak-proof washing machine inlet pipe. Background Technology

[0002] A washing machine is a device that uses washing water and detergent to remove dirt from clothes, bedding, and other laundry items stored in its drum through washing, rinsing, spin-drying, and drying processes. Both top-loading and front-loading washing machines require a water inlet pipe connected to a tap. However, existing water inlet pipes, when connected to the tap with a connector, are prone to loosening under tension, causing leaks and affecting usability. To address this, patent application number 202323378937.6 discloses a leak-proof washing machine water inlet pipe, including an inlet pipe with a connector on its upper outer surface. A faucet is provided at the upper end of the faucet, and a fastening mechanism is provided at the lower end of the outer wall of the faucet. The fastening mechanism includes a fixing ring, a bearing, a threaded ring, a first ear plate, a plug rod, a second ear plate, a threaded ring, a sealing gasket, a first slot, a guide rod, a first groove, a second groove, a T-shaped rod, a spring, a moving groove, an arc-shaped plug, and a second slot. The threaded ring is located in the middle of the outer wall of the faucet, the threaded ring is located on the outer wall of the faucet, and the fixing ring is located at the lower end of the threaded ring. A leak-proof washing machine inlet pipe can easily fasten the inlet pipe to the faucet, making the connection more stable and avoiding the loosening and leakage caused by external pulling force, thus affecting the use. It has a leak-proof function and brings better application prospects.

[0003] The aforementioned patent discloses a leak-proof washing machine inlet pipe that improves the installation stability of the faucet and inlet pipe by fixing the connector to the first ear plate. However, it still has the following shortcomings in use: 1. The single-position fixing method cannot be adjusted when the sealing gasket needs to be squeezed to adjust the seal, thus affecting the leak-proof effect. In addition, the fixing structure is connected to the faucet by a threaded connection, which still cannot effectively fix the pipe when the thread is loose; 2. The method of fixing the connector to the inlet pipe means that the entire pipe needs to be replaced when it is damaged, which is costly. In view of the above, this application proposes a leak-proof washing machine inlet pipe. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a leak-proof washing machine inlet pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leak-proof washing machine inlet pipe includes a main body of the washing machine inlet pipe that cooperates with a faucet. The main body of the washing machine inlet pipe includes a pipe body, and a connector is fixedly connected to the top end of the pipe body. The connector and the faucet are equipped with the same sealing and leak-proof connection mechanism, and a limiting ring is fixedly sleeved on the faucet.

[0007] The sealing and leak-proof connection mechanism includes:

[0008] A round box with an open bottom, handles fixedly connected to both sides of the round box, and threaded holes on the inner wall of the top, into which the faucet is threadedly fitted.

[0009] The sealing and leak-proof component is adhesively fitted inside the circular box and threaded hole. By setting up the sealing and leak-proof component, a seal can be achieved between the faucet and the connector.

[0010] The connecting sleeve is sealed and rotated inside the circular box and is installed with the connector.

[0011] The anti-detachment component is installed on the circular box and the limiting ring. The anti-detachment component is used to limit the mutual pulling between the circular box and the limiting ring.

[0012] Preferably, the inner wall of the connecting sleeve is bonded and fixed to the outer side of the connecting head.

[0013] Preferably, the connecting sleeve and the connecting head are detachably connected.

[0014] Preferably, the connecting sleeve has a sealing sleeve inside, the inner wall of which is in close contact with the outer side of the connector. A fixing ring is fixedly fitted on the outer side of the connector. The bottom of the connecting sleeve has four threaded grooves in an annular shape. T-shaped fixing bolts are threaded in the threaded grooves, and the fixing ring is threaded on the four T-shaped fixing bolts. The connector can be separated from the connecting sleeve in the future by means of threaded connection between the T-shaped fixing bolts and the threaded grooves.

[0015] Preferably, the sealing and leak-proof assembly includes a first sealing ring adhesively fitted inside a circular box, the bottom of which is in movable contact with the top of the connector and the top of the connecting sleeve; a second sealing ring movably fitted inside a threaded hole, which is in movable contact with and communicates with the top of the first sealing ring; the top of the second sealing ring movably contacts the bottom of the faucet; the first and second sealing rings achieve a sealed connection between the connector and the circular box; a third sealing ring, which is in movable contact with the threaded hole, is fixedly fitted to the top of the circular box; the top of the third sealing ring is in close contact with the bottom of a limiting ring; the cooperation of the third sealing ring and the limiting ring seals the gap between the threaded hole and the faucet.

[0016] Preferably, the limiting anti-detachment component includes a mounting ring movably fitted onto a circular box. Multiple first slots are provided on both sides of the circular box. A first locking rod is movably fitted into one of the first slots on the same side of the circular box. Second slots are provided on both sides of the limiting ring, and a second locking rod is movably fitted into each second slot. The mounting ring is slidably fitted onto two first locking rods and two second locking rods. Pull rods are provided on both sides of the mounting ring. The sides of the two pull rods that are close to each other are fixedly connected to the corresponding first and second locking rods, respectively. Two springs are fixedly connected between the side of the pull rod closest to the mounting ring and the outer surface of the mounting ring. Four springs are movably fitted onto the corresponding first and second locking rods, respectively. When the springs are in a stretched state and the tension is released, the corresponding pull rods drive the first and second locking rods.

[0017] Preferably, the outer side of the connecting sleeve has an annular groove with an open top, and two sealed bearings are fixedly fitted inside the circular box. The inner side of the inner ring of the sealed bearing is fixedly connected to the inner wall of the annular groove, and the sealed bearing serves to allow the connecting sleeve to rotate and be installed.

[0018] Preferably, a threaded limiting groove is provided on the bottom left side of the connecting sleeve, and a T-shaped limiting bolt is threadedly embedded on the left side of the circular box. The threaded limiting groove is adapted to the T-shaped limiting bolt. By cooperating with the T-shaped limiting bolt and the threaded limiting groove, the connecting sleeve can be limited and fixed to prevent the tube from rotating during use.

[0019] Compared with existing technologies, the beneficial effects of this utility model are:

[0020] 1. By setting up a sealing and leak-proof component, two seals can be made when the water inlet pipe is connected to the faucet through the connector. The two-point sealing method can effectively improve the sealing effect and reduce the risk of leakage.

[0021] 2. By setting up the anti-detachment component, after the water inlet pipe is connected to the faucet through the connector, the circular box and the limiting ring can be pulled and restricted, thereby achieving the pull restriction of the faucet and the circular box. Even if the threads between the faucet and the threaded hole become loose, the pull restriction can effectively prevent the faucet and the circular box from separating, further improving the sealing and leak-proof effect. In addition, by setting multiple first slots, when it is necessary to continue to rotate the circular box upward to squeeze and adjust the sealing of the second sealing ring, the first locking rod can still be locked into an aligned slot, without affecting the pull restriction or the adjustment of the sealing. Furthermore, by locking and simultaneously pulling and restricting the circular box and the limiting ring, the risk of loosening of the threaded connection restriction can be avoided, improving its pull restriction and fixing effect.

[0022] 3. By using T-shaped fixing bolts, threaded grooves, and retaining rings, subsequent replacements only require replacing the connector and pipe body, eliminating the need to replace the entire connecting component and reducing replacement costs.

[0023] This utility model, through a series of structural designs, achieves a seal between the pipe body and the faucet via two sealing points, effectively improving the sealing effect and reducing the risk of leakage. Furthermore, the clamping and pulling mechanism after sealing effectively reduces the risk of leakage caused by loose threads, further enhancing the leak-proof effect. Additionally, the multiple first-slot design does not affect the pulling restriction or the adjustment of the seal, while also avoiding the risk of loosening due to threaded connections. Moreover, during replacement, only the connector and pipe body need to be replaced, eliminating the need to replace the entire connecting component, thus reducing replacement costs.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figure 1-3 A water inlet pipe for a washing machine that prevents leakage includes a main body of the washing machine water inlet pipe that cooperates with a faucet 102. The main body of the washing machine water inlet pipe includes a pipe body 100. A connector 101 is fixedly connected to the top of the pipe body 100. The same sealing and water-proof connection mechanism 2 is installed on the connector 101 and the faucet 102. A limiting ring 103 is fixedly sleeved on the faucet 102.

[0033] The sealing and leak-proof connection mechanism 2 includes:

[0034] The circular box 201 has an opening at the bottom. Both sides of the circular box 201 are fixedly connected to handles, which can be used to rotate the circular box 201. A threaded hole 202 is opened on the inner wall of the top. The faucet 102 is threaded into the threaded hole 202. The bottom of the outer side of the faucet 102 has an external thread, which is threaded to the threaded hole 202.

[0035] A sealing and leak-proof component is adhesively fitted into the circular box 201 and the threaded hole 202;

[0036] The connecting sleeve 204 is rotatably installed in the circular box 201. The inner wall of the connecting sleeve 204 is bonded and fixed to the outer side of the connector 101. The outer side of the connecting sleeve 204 has an annular groove with an open top. Two sealed bearings are fixedly installed in the circular box 201. The inner side of the inner ring of the sealed bearing is fixedly connected to the inner wall of the annular groove. The sealed bearings serve to allow the connecting sleeve 204 to be rotatably installed.

[0037] The sealing and leak-proof assembly includes a first sealing ring 203 adhesively fitted inside a circular box 201. The bottom of the first sealing ring 203 is in movable contact with the top of the connector 101 and the top of the connecting sleeve 204. A second sealing ring 207 is movably fitted inside a threaded hole 202, in movable contact with and communicating with the top of the first sealing ring 203. The top of the second sealing ring 207 is in movable contact with the bottom of the faucet 102. The first sealing ring 203 and the second sealing ring 207 achieve a sealed connection between the connector 101 and the circular box 201. The top of the box 201 is fitted with a third sealing ring 208 that communicates with the threaded hole 202. The inner side of the threaded hole 202 is provided with an annular fitting groove with an open top. The inner wall of the annular fitting groove is fixedly connected to the outer side of the third sealing ring 208. The third sealing ring 208 is movably fitted on the faucet 102. The top of the third sealing ring 208 is in close contact with the bottom of the limiting ring 103. Through the cooperation of the third sealing ring 208 and the limiting ring 103, the gap between the threaded hole 202 and the faucet 102 can be sealed.

[0038] A limiting anti-detachment component is installed on the circular box 201 and the limiting ring 103. The limiting anti-detachment component is used to restrict the mutual pulling of the circular box 201 and the limiting ring 103.

[0039] The anti-detachment component includes a mounting ring 219 movably fitted onto a circular box 201. Multiple first slots 212 are provided on both sides of the circular box 201. A first locking rod 214 is movably fitted into one of the first slots 212 on the same side of the circular box 201. Second slots 209 are provided on both sides of the limiting ring 103. A second locking rod 210 is movably fitted into the second slot 209. The mounting ring 219 is slidably fitted onto two first locking rods 214 and two second locking rods 210. First sliding holes and second sliding holes are provided on the inner walls of both sides of the mounting ring 219. The inner walls of the first sliding holes and the second sliding holes... The inner wall slides in contact with the outer side of the first locking rod 214 and the outer side of the second locking rod 210 respectively. Both sides of the mounting ring 219 are provided with pull rods 211. The side of the two pull rods 211 that is close to each other is fixedly connected to the corresponding first locking rod 214 and the second locking rod 210 respectively. The side of the pull rod 211 that is close to the mounting ring 219 is fixedly connected to the outer surface of the mounting ring 219 with two springs 213. The four springs 213 are movably sleeved on the corresponding first locking rod 214 and the second locking rod 210 respectively. When the springs 213 are in the stretched state and the tension is released, the first locking rod 214 and the second locking rod 210 are driven through the corresponding pull rods 211.

[0040] The bottom left side of the connecting sleeve 204 is provided with a threaded limiting groove 205, and the left side of the circular box 201 is threaded with a T-shaped limiting bolt 206. The left side of the circular box 201 is provided with a first bolt hole that is threadedly connected to the T-shaped limiting bolt 206. The T-shaped limiting bolt 206 can move laterally while rotating in the first bolt hole. The threaded limiting groove 205 is adapted to the T-shaped limiting bolt 206. Through the cooperation of the T-shaped limiting bolt 206 and the threaded limiting groove 205, the connecting sleeve 204 can be limited and fixed to prevent the tube body 100 from rotating during use.

[0041] This embodiment can achieve sealing of the pipe body 100 after it is connected to the faucet 102 through the connector 101 by two sealing methods, which can effectively improve the sealing effect and reduce the risk of water leakage. After sealing, the clamping and pulling method can effectively reduce the risk of water leakage caused by loose threads, further improving the water leakage prevention effect. In addition, by setting multiple first grooves 212, the pulling restriction is not affected, nor is the adjustment of the sealing performance, and the risk of loosening of the threaded connection restriction can be avoided.

[0042] The method of use in this embodiment is as follows: When the pipe body 100 is sealed and connected to the faucet 102, the anti-detachment component is separated from the circular box 201 and the limiting ring 103. The threaded hole 202 on the circular box 201 is aligned with the faucet 102, and the threaded hole 202 is screwed onto the faucet 102 by rotating the circular box 201. During the screwing process, the third sealing ring 208 is gradually fitted onto the faucet 102. When the top of the third sealing ring 208 is in close contact with the bottom of the limiting ring 103, the bottom of the faucet 102 is in close contact with the top of the second sealing ring 207. Through the cooperation of the first sealing ring 203 and the second sealing ring 207, the pipe body 100 is sealed and connected to the faucet 102 through the connector 101. In addition, the third sealing ring 208 and the limiting ring 103 further wrap and seal the outside of the faucet 102, which can effectively improve the sealing effect and reduce the risk of leakage.

[0043] After connection, pull the two levers 211 in a direction away from each other. The levers 211 cause the corresponding first locking lever 214 and second locking lever 210 to retract outward. While the levers 211 are moving, they stretch the corresponding two springs 213. Then, the mounting ring 219 is fitted onto the circular box 201, aligning the second locking lever 210 with the corresponding second locking groove 209. At this time, the second locking lever 210 is aligned with one of the first locking grooves 212. Then, the tension on the levers 211 is released. The elastic force of the springs 213, which are in a stretched state, drives the first locking lever 214 and second locking lever 210 to move through the corresponding levers 211. The first locking lever 214 and second locking lever 210 respectively engage with the corresponding second locking groove 209 and first locking groove 212. At this time, the engagement of the first locking lever 214 and the first locking groove 212, as well as the engagement of the second locking lever 210 and the second locking groove 209, are complete. With the cooperation of the two, the pull restriction between the circular box 201 and the limiting ring 103 can be realized, thereby realizing the pull restriction between the faucet 102 and the circular box 201. Even if the threads between the faucet 102 and the threaded hole 202 become loose, the pull restriction can effectively prevent the faucet 102 and the circular box 201 from separating, further improving the sealing and leak-proof effect. Moreover, by setting multiple first slots 212, when it is necessary to continue to rotate the circular box 201 upwards to squeeze and adjust the sealing of the second sealing ring 207, the first locking rod 214 can still be locked into an aligned first slot 212, without affecting the pull restriction or the adjustment of the sealing. In addition, by locking the circular box 201 and the limiting ring 103 to pull and restrict at the same time, the risk of loosening of the threaded connection restriction can be avoided, improving its pull restriction and fixing effect.

[0044] In addition, after connection, the T-shaped limiting bolt 206 can be rotated in the forward direction. The T-shaped limiting bolt 206 rotates and drills into the threaded limiting groove 205 to fix the connecting sleeve 204, which can effectively prevent the pipe body 100 from rotating during use.

[0045] Example 2

[0046] like Figure 4-5As shown, this embodiment differs from Embodiment 1 in that the connecting sleeve 204 and the connecting head 101 are detachably connected. A sealing sleeve 215 is adhesively fitted inside the connecting sleeve 204, and the inner wall of the sealing sleeve 215 is in close contact with the outer side of the connecting head 101. The sealing sleeve 215 achieves a seal between the outer side of the connecting head 101 and the inner side of the connecting sleeve 204. A fixing ring 216 is fixedly fitted on the outer side of the connecting head 101. Four threaded grooves 218 are annularly opened at the bottom of the connecting sleeve 204. T-shaped fixing bolts 217 are threadedly fitted inside the threaded grooves 218. The fixing ring 216 is threadedly fitted onto the four T-shaped fixing bolts 217. Four second bolt holes are annularly opened at the top of the fixing ring 216, and the second bolt holes are threadedly connected to the corresponding T-shaped fixing bolts 217. Through the threaded connection of the T-shaped fixing bolts 217 and the threaded grooves 218, the connecting head 101 and the connecting sleeve 204 can be separated subsequently.

[0047] This embodiment allows for replacement of only the connector 101 and the tube body 100, eliminating the need to replace the entire connecting component and reducing replacement costs.

[0048] The usage method of this embodiment is as follows: Unlike Embodiment 1, this embodiment also has the following functions: the connector 101 and the connecting sleeve 204 are detachable. When the tube body 100 is subsequently replaced, the circular box 1 can be separated from the connector 101. The four T-shaped fixing bolts 217 can be rotated forward. As the T-shaped fixing bolts 217 rotate, they move out of the corresponding threaded grooves 218, releasing the restriction between the connecting sleeve 204 and the connector 101. At this time, the connector 101 on the new tube body 100 can be fitted into the connecting sleeve 204 and moved upward until it is in close contact with the bottom of the first sealing ring 203. Then, the four T-shaped fixing bolts 217 can be rotated in the reverse direction and screwed into the corresponding threaded grooves 218, thus achieving the connection between the connector 101 and the connecting sleeve 204. The connector 101 and the tube body 100 are detachable, so only the connector 101 and the tube body 100 need to be replaced during replacement, without needing to replace the entire connecting component, thus reducing replacement costs.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
