[0006] The hose has connecting rings fixed at both its bottom and top ends. Sealing rings are glued to the opposing sides of the two connecting rings. The upper sealing ring is squeezed into contact with the bottom end of the faucet. An internal threaded connector is movably sleeved on the outer side of the bottom end of the hose.
[0007] The internal threaded sleeve is fitted on the outside of the threaded protrusion and is movably fitted on the outside of the top of the hose. Two connecting rings are respectively connected to the inner wall of the internal threaded sleeve and the internal threaded connector on the side that are close to each other.
[0008] A rotating assembly is installed on the outside of the internal threaded sleeve; the rotating assembly is used to drive the internal threaded sleeve to rotate and to slide vertically on the outside of the internal threaded sleeve when a vertical force is applied.
[0009] The locking assembly consists of two sets, which are respectively installed on the inner walls of the two sides of the internal threaded sleeve and fixedly connected to the rotating assembly, and in movable contact with the top of the threaded protrusion. The locking assembly is used to lock with the top of the threaded protrusion to enhance the anti-disengagement effect, and to release the locking with the top of the threaded protrusion when the rotating assembly slides upward.
[0010] Preferably, the upper connecting ring of the two connecting rings is bonded and fixed to the bottom inner wall of the internal threaded sleeve, while the lower connecting ring is in movable contact with the top inner wall of the internal threaded joint.
[0011] Preferably, the upper connecting ring of the two connecting rings is in movable contact with the bottom inner wall of the internal threaded sleeve, and the lower connecting ring is bonded and fixed to the top inner wall of the internal threaded joint.
[0012] Preferably, the two connecting rings are in active contact with the inner wall of the inner threaded sleeve and the inner threaded joint on the side adjacent to each other.
[0013] Preferably, the rotary assembly includes a rotating sleeve movably fitted on the outside of the internal threaded sleeve. The outer top of the rotating sleeve is integrally provided with an outer edge. Multiple anti-slip strips are fixedly connected in a ring at equal intervals on the outer side of the rotating sleeve.

Slide blocks are fixedly connected on the inner walls of both sides of the rotating sleeve, and the slide blocks are slidably connected in the corresponding slide grooves.
[0014] Preferably, the locking assembly includes a locking block that movably contacts the top of the threaded protrusion. Rectangular through holes are provided on both inner walls of the internal threaded sleeve, and these rectangular through holes communicate with corresponding sliding grooves. The locking block is slidably fitted into the corresponding rectangular through hole. A support ring is fixedly installed inside the rectangular through hole. A spring is fixedly connected between the adjacent sides of the two support rings and the corresponding locking block. A rotating sleeve that movably contacts the bottom of the corresponding slider is rotatably installed between the front and rear inner walls of the sliding groove. A soft steel wire rope is fixedly connected to the opposing sides of the two locking blocks. One end of the soft steel wire rope passes around the bottom of the corresponding rotating sleeve and is fixedly connected to the bottom of the slider. The support ring and the spring are both movably fitted onto the corresponding soft steel wire rope.

[0019] This utility model incorporates a series of structures that allow for threaded connection with the threaded protrusion of a faucet and a locking mechanism at its top. This locking mechanism prevents the thread from easily rotating downwards, reducing the risk of the thread loosening and disengaging due to vibration. The combination of threaded connection and locking mechanism creates a double-locking, double-stable, and secure connection to prevent disengagement. This enhances the anti-disengagement effect, reduces the risk of disengagement due to water pressure vibration and other factors during prolonged use, and improves operational stability.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 4As shown, this embodiment proposes a three-layer explosion-proof double-lock reinforced washing machine inlet pipe, including a washing machine inlet pipe body installed on a faucet 100. The outer bottom of the faucet 100 is provided with a threaded protrusion 200. The washing machine inlet pipe body includes:
[0027] The hose 1 has connecting rings 105 fixed at both its bottom and top ends. Sealing rings 106 are glued to the opposing sides of the two connecting rings 105. The upper sealing ring 106 is squeezed and in contact with the bottom end of the faucet 100. An internal threaded connector 2 is movably sleeved on the outer side of the bottom end of the hose 1. The hose 1 includes a flexible waterproof tube body 101, a wear-resistant layer 103 set inside the flexible waterproof tube body 101, an anti-corrosion layer 104 sprayed inside the wear-resistant layer 103, and a wire mesh protective layer 102 fixed on the outer side of the flexible waterproof tube body 101. The wear-resistant layer 103 is used to enhance the wear resistance of the inner side. The anti-corrosion layer 104 is an anti-corrosion coating used to enhance the anti-corrosion effect. The wire mesh protective layer 102 is used to enhance the wear resistance and scratch resistance of the outer side and reduce the risk of bursting due to accidental scratches and abrasions.
[0028] The internal thread sleeve 3 is threaded outside the threaded protrusion 200 and movably sleeved outside the top of the hose 1. Two connecting rings 105 are respectively connected to the inner wall of the internal thread sleeve 3 and the internal thread connector 2 on the same side.
[0029] A rotating assembly is installed on the outside of the internal threaded sleeve 3; the rotating assembly is used to drive the internal threaded sleeve 3 to rotate and to slide vertically on the outside of the internal threaded sleeve 3 when a vertical force is applied.
[0030] The locking assembly consists of two sets, which are respectively installed on the inner walls of both sides of the internal threaded sleeve 3 and fixedly connected to the rotating assembly, and in movable contact with the top of the threaded protrusion 200. The locking assembly is used to lock with the top of the threaded protrusion 200 to enhance the anti-disengagement effect, and to release the locking with the top of the threaded protrusion 200 when the rotating assembly slides up.
[0031] Specifically, the upper connecting ring 105 of the two connecting rings 105 is bonded and fixed to the bottom inner wall of the internal thread sleeve 3, and the lower connecting ring 105 is in movable contact with the top inner wall of the internal thread connector 2. Under this connection environment, the internal thread sleeve 3 needs to be rotated and threadedly connected to the faucet 100 first, and then the lower movable contact forms an internal thread connector 2 that can be rotated independently and screwed onto the washing machine water inlet thread head.
[0032] Furthermore, the upper connecting ring 105 of the two connecting rings 105 is in movable contact with the bottom inner wall of the internal thread sleeve 3, and the lower connecting ring 105 is bonded and fixed to the top inner wall of the internal thread connector 2. In this connection environment, it is necessary to first screw the internal thread connector 2 to the washing machine water inlet thread head, and then use the upper movable contact to form the independently rotatable internal thread sleeve 3 to screw it to the faucet 100 thread, providing another application method.
[0033] Furthermore, the two connecting rings 105 respectively make movable contact with the inner wall of the inner threaded sleeve 3 and the inner threaded connector 2 on the side closest to each other. Under this connection environment, the inner threaded sleeve 3 and the inner threaded connector 2 can be connected in any order, providing another application method.
[0034] Furthermore, the rotating assembly includes a rotating sleeve 301 movably sleeved on the outside of the internal threaded sleeve 3. The top of the outer side of the rotating sleeve 301 is integrally provided with an outer edge. Multiple anti-slip strips are fixedly connected in an annular pattern at equal intervals on the outer side of the rotating sleeve 301. Slide grooves 3011 are opened on the top of both sides of the internal threaded sleeve 3. Slide blocks 3012 are fixedly connected on the inner walls of both sides of the rotating sleeve 301. The slide blocks 3012 are slidably connected in the corresponding slide grooves 3011. The rotating sleeve 301, anti-slip strips, slide blocks 3012 and slide grooves 3011 cooperate. When the rotating sleeve 301 is rotated, the rotating sleeve 301 drives the two slide blocks 3012 to rotate. The two slide blocks 3012 drive the internal threaded sleeve 3 to rotate as a whole through the two slide grooves 3011. The rotation of the internal threaded sleeve 3 realizes the screwing or screwing connection with the threaded protrusion 200. When an upward force is applied to the rotating sleeve 301, the rotating sleeve 301 drives the two slide blocks 3012 to slide vertically in the corresponding slide grooves 3011 respectively.
[0035] Furthermore, the locking assembly includes a locking block 3021 that movably contacts the top of the threaded protrusion 200. Rectangular through holes 302 are provided on both inner walls of the inner threaded sleeve 3. These rectangular through holes 302 communicate with corresponding sliding grooves 3011. The locking block 3021 is slidably fitted within the corresponding rectangular through hole 302. A support ring 3022 is fixedly installed within the rectangular through hole 302. A spring 3023 is fixedly connected between the adjacent sides of the two support rings 3022 and the corresponding locking block 3021. A corresponding slider 30 is rotatably mounted between the front and rear inner walls of the sliding groove 3011. 12 The bottom of the rotating sleeve 3024 is in contact with the sliding groove 3011. The inner walls of the front and rear sides of the sliding groove 3011 are fixedly connected to the support shaft. The inner side of the rotating sleeve 3024 and the outer side of the support shaft are fixedly fitted with a bearing, which has the effect of rotating the rotating sleeve 3024. The two locking blocks 3021 are fixedly connected to the opposing sides of the two locking blocks 3021 with soft steel wire ropes 3025. One end of the soft steel wire rope 3025 passes around the bottom of the corresponding rotating sleeve 3024 and is fixedly connected to the bottom of the slider 3012. The support ring 3022 and the spring 3023 are both movably fitted on the corresponding soft steel wire ropes 3025.
[0036] The locking block 3021, rectangular through hole 302, support ring 3022, spring 3023, rotating sleeve 3024, and soft steel wire rope 3025 are configured to work together. The two locking blocks 3021 are used to lock the top of the threaded protrusion 200, thereby restricting the internal thread sleeve 3 and reducing the risk of the thread loosening and disengaging due to vibration. The combination of threaded connection and locking restriction forms a double-locking installation connection, which enhances the anti-disengagement effect. When the rotating sleeve 301 is pushed up by the operator, the slider 3012 moves upward. The two sliders 3012 drive the two locking blocks 3021 to move repulsively through the two soft steel wire ropes 3025, disengaging from the top of the threaded protrusion 200 and releasing the locking function, allowing for rotation operation.
[0037] The usage method of this embodiment is as follows: When using the three-layer explosion-proof double-lock reinforced washing machine inlet pipe, when connecting it to the faucet 100, first screw the upper inner side of the inner threaded sleeve 3 onto the threaded protrusion 200 of the faucet 100. Then push the rotating sleeve 301 upward to drive the two sliders 3012 to slide upward in the corresponding sliding grooves 3011. At this time, the two sliders 3012 drive the two locking blocks 3021 to move repulsively through the two soft steel wire ropes 3025, and compress the two springs 3023. At this time, the locking blocks 3021 retract into the corresponding rectangular through holes 302 to avoid jamming with the threaded protrusion 200. In the upward state, directly rotate the rotating sleeve 301. At this time, the rotating sleeve 301 drives the inner threaded sleeve 3 to continue rotating through the two sliders 3012, so that it gradually screws into the outer threaded protrusion 200. The upper connecting ring 105 drives the upper sealing ring 106 to be squeezed and sealed to the bottom of the faucet 100. Then, the upward push force on the rotating sleeve 301 is released. At this time, the elastic force of the two springs 3023 in the compressed state drives the two locking blocks 3021 to repel and rebound out, and lock onto the top of the threaded protrusion 200. By using the two locking blocks 3021 to lock onto the top of the threaded protrusion 200, the inner thread sleeve 3 is locked and restricted, so that it cannot be directly rotated and moved down, reducing the risk of the thread rotating loose and moving down due to vibration. By using the threaded connection and locking restriction, a double-locking installation connection effect is formed, thereby achieving a double stable and safe connection with the faucet 100 to prevent separation. This strengthens the anti-separation effect, reduces the risk of separation due to water pressure vibration and other factors during long-term use, and improves the stability of use.
[0038] Then tighten the internal thread connector 2 to the water inlet thread of the washing machine. The wear-resistant layer 103 enhances the wear resistance of the inner side of the flexible waterproof pipe 101, the anti-corrosion layer 104 enhances the anti-corrosion effect of the inner side of the flexible waterproof pipe 101, and the wire mesh protective layer 102 enhances the wear resistance and scratch resistance of the outer side of the flexible waterproof pipe 101, reducing the risk of bursting due to accidental scratches or abrasions.
[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
