DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, the utility model provides a washing machine drain pipe, including:

[0031] The washing machine body 1 has a water outlet pipe 2 fixedly sleeved at the bottom end of the right rear side of the washing machine body 1, a connecting pipe 3 movably sleeved inside the water outlet pipe 2, and a drain pipe 16 fixedly installed at the right end of the connecting pipe 3;

[0032] A connecting mechanism is provided on the outer surface of the connecting pipe 3;

[0033] Among them, the connecting mechanism includes a limiting block 4, the outer surface of the limiting block 4 is fixedly connected to the outer surface of the connecting pipe 3, the outer surface of the left end of the limiting block 4 is movably connected to the inside of the water outlet pipe 2, the internal movability of the limiting block 4 is connected with a moving block 5, the left end of the moving block 5 is movably connected with a rack 6, the outer surface of the rack 6 is movably connected to the inside of the limiting block 4, the left end of the first spring 7 is fixedly installed with the inside of the limiting block 4, the outer surface of the rack 6 is meshed with a rotating gear 8, the internal movability of the rotating gear 8 is sleeved with an arc block 9, the bottom end of the arc block 9 is fixedly connected to the outer surface of the connecting pipe 3, the outer surface of the rotating gear 8 is fixedly installed with a rotating rod 10, the outer surface of the left end of the rotating rod 10 is movably connected with a fixing ring 11, and the inside of the fixing ring 11 is fixedly sleeved with the outer surface of the water outlet pipe 2.

[0034] Due to the design of the limit block 4, the movement of the moving block 5 will be limited. When the moving block 5 moves to the left along the inside of the limit block 4, the rack 6 will move to the left along the inside of the limit block 4 under the push of the moving block 5. Since the rack 6 is engaged with the rotating gear 8, the rack 6 will drive the rotating gear 8 to rotate with the arc block 9 as the axis. At the same time, the rack 6 will compress the first spring 7. Due to the elastic force of the first spring 7, the movement of the rack 6 will be well reset. Then the rotating rod 10 will rotate driven by the rotating gear 8. When the left ends of the four rotating rods 10 are released from contact with the fixed ring 11 during rotation, the rotating rod 10 and the fixed ring 11 will release the locking effect on the connection between the water outlet pipe 2 and the connecting pipe 3.

[0035] The outer surface of the connecting pipe 3 is fixedly sleeved with a threaded sleeve 12 , the outer surface of the threaded sleeve 12 is threadedly sleeved with a rotating block 13 , and the outer surface of the right end of the rotating block 13 is fixedly sleeved with a twisting block 14 .

[0036] Since the outer surface of the threaded sleeve 12 is engaged with the internal thread of the rotating block 13, the rotating block 13 will move left and right when it rotates along the outer surface of the threaded sleeve 12. Due to the design of the twisting block 14, the operator can drive the rotating block 13 to rotate by twisting the twisting block 14.

[0037] The outer surface of the left end of the rotating block 13 is movably sleeved with a moving ring 15 , and the interior of the moving ring 15 is fixedly connected to the outer surface of the moving block 5 .

[0038] Due to the limiting effect of the limit block 4, the moving block 5 can only move left and right. When the rotating block 13 moves left and right, since the interior of the moving ring 15 is movably connected to the outer surface of the rotating block 13, the rotating block 13 will drive the moving block 5 to move left and right along the interior of the limit block 4 through the moving ring 15.

[0039] A fixing block 18 is fixedly mounted on the top of the right side of the washing machine body 1 , a fixing shaft 19 is fixedly sleeved inside the fixing block 18 , and a rotating block 20 is movably sleeved on the outer surface of the fixing shaft 19 .

[0040] Since the rotating block 20 is movably connected to the fixed shaft 19 , the rotating block 20 can rotate around the fixed shaft 19 as the axis.

[0041] A rotating gear 21 is fixedly mounted on the bottom end of the rotating block 20 , and the interior of the rotating gear 21 is movably sleeved with the outer surface of the fixed shaft 19 .

[0042] Since the rotating gear 21 is movably connected to the fixed shaft 19 and the top end of the rotating gear 21 is fixedly connected to the bottom end of the fixed shaft 19, when the rotating gear 21 rotates around the fixed shaft 19, it drives the rotating block 20 to rotate.

[0043] The fixed block 18 is movably connected to an arc plate 22 inside, and a tooth plate 23 is fixedly mounted on the outer surface of the arc plate 22 . The outer surface of the tooth plate 23 is meshed with the outer surface of the rotating gear 21 .

[0044] Due to the limitation inside the fixed block 18, the arc plate 22 can only move left and right. When the arc plate 22 moves to the left, the toothed plate 23 will move to the left driven by the arc plate 22. Since the outer surface of the toothed plate 23 is meshed with the outer surface of the rotating gear 21, when the toothed plate 23 moves to the left, it will drive the rotating gear 21 to rotate.

[0045] A second spring 24 is fixedly mounted on the left end of the arc-shaped plate 22 , and the left end of the second spring 24 is fixedly connected to the interior of the fixing block 18 .

[0046] When the arc-shaped plate 22 moves to the left, the second spring 24 will be compressed. Due to the elastic force of the second spring 24, the overall movement of the arc-shaped plate 22 will be well restored.

[0047] The top of the fixed block 18 is fixedly mounted with a fixing frame 25 , the top of the fixing frame 25 is movably sleeved with a round rod 27 , the top of the round rod 27 is fixedly mounted with a pull block 26 , and the bottom of the round rod 27 is fixedly mounted with a round plate 28 .

[0048] Since the outer surface of the round rod 27 is movably connected to the inside of the fixing frame 25, the round rod 27 can move up and down along the inside of the fixing frame 25. Due to the design of the pull block 26, the operator can drive the round rod 27 to move up and down through the pull block 26. When the round rod 27 moves up and down, it will drive the circular plate 28 to move up and down.

[0049] A third spring 29 is fixedly mounted on the top end of the circular plate 28 , and the top end of the third spring 29 is fixedly connected to the inside of the fixing frame 25 .

[0050] When the circular plate 28 moves upward, the third spring 29 is compressed. Due to the elastic force of the third spring 29, the overall movement of the circular plate 28 is effectively reset.

[0051] The bottom end of the third spring 29 is fixedly mounted with a clamping block 17 . The outer surface of the clamping block 17 is movably connected to the inner portion of the fixed block 18 . The bottom end of the clamping block 17 is movably connected to the top end of the arc plate 22 .

[0052] When the top of the arc plate 22 moves to the bottom of the block 17, the circular plate 28 as a whole will move downward to reset under the elastic force of the third spring 29. When the bottom of the block 17 moves to the top of the arc plate 22, the movement of the arc plate 22 as a whole will be blocked by the block 17, thereby locking the movement of the arc plate 22 as a whole.

[0053] The working principle and use process of this utility model:

[0054] When the operator needs to assemble the connecting pipe 3 as a whole with the water outlet pipe 2, the operator twists the twisting block 14. At this time, the rotating block 13 will rotate along the outer surface of the threaded sleeve 12 under the drive of the twisting block 14. Since the interior of the rotating block 13 is threadedly sleeved with the outer surface of the threaded sleeve 12, when the rotating block 13 rotates along the outer surface of the threaded sleeve 12, it will move to the left. Due to the limitation of the moving block 5 by the limit block 4, the rotating block 13 will drive the moving block 5 to move to the left along the inside of the limit block 4 through the moving ring 15. At this time, the outer surface of the moving block 5 will squeeze and push the rack 6 during the left movement, so that the rack 6 moves to the left along the inside of the limit block 4. At this time, the first spring 7 will be in a compressed state, and since the outer surface of the rack 6 is meshed with the outer surface of the rotating gear 8, at the same time, the rack 6 will drive the rotating gear 8 to rotate with the arc block 9 as the axis during the left movement. In this process, the rotating rod 10 will be driven by the rotating gear 8 with the arc block 9 as the axis. When the cam 11 is in the closed position, the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position, and the cam 13 is in the closed position, so that the cam 13 is in the closed position,

[0055] When the washing machine body 1 stops running as a whole and needs to store the drain pipe 16 as a whole, the operator holds the drain pipe 16 and pushes the curved plate 22. At this time, the curved plate 22 will move to the left along the inside of the fixed block 18. At this time, the second spring 24 will become compressed under the movement of the curved plate 22. At the same time, the curved plate 22 will drive the toothed plate 23 to move to the left. Since the outer surface of the toothed plate 23 is meshed with the outer surface of the rotating gear 21, the toothed plate 23 will drive the rotating gear 21 to rotate with the fixed shaft 19 as the axis. Then the rotating block 20 will be driven by the rotating gear 21 to rotate with the fixed shaft 19 as the axis. The fixed shaft 19 rotates as the axis. When the outer surface of the rotating block 20 contacts the outer surface of the drain pipe 16 during rotation, the rotating block 20 will cooperate with the fixed block 18 to fix the drain pipe 16. At the same time, the inner part of the top of the arc plate 22 will move to the left to the bottom end of the block 17. Due to the elastic force of the third spring 29, the block 17 will move downward and reset under the drive of the third spring 29. When the bottom end of the block 17 moves to the inner part of the top of the arc plate 22, the block 17 will lock the overall movement of the arc plate 22, thereby realizing the function of convenient storage of the drain pipe 16.
