[0018] Preferably, the linkage component includes a support one fixedly connected to the side wall of the movable block, a connecting rod rotatably connected to the end of the support one away from the movable block, a support two rotatably connected to the end of the connecting rod away from the support one, a sliding block fixedly connected to the end of the support two away from the connecting rod, a fixed rod movably passing through the side wall of the sliding block, and the fixed rod being fixedly connected to the inner wall of the positioning frame.

[0021] By adopting the above technical solution, the vertical component drives the buffer assembly to move horizontally, thereby making the contact component fit against the side wall of the pipe. The horizontal movement of the bottom sliding block drives the bottom sliding block to move vertically upward, thereby making the contact component fit against the outer wall of the pipe from the bottom. The knob is rotated and limited by the positioning pin.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

It has stronger stability than foam boxes or foam boards.

[0024] 2.

[0039] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0040] This application discloses a water pump box for a washing machine.

[0041] Reference Figures 1-3 A water pump box for a washing machine includes a housing 1, which includes a base and a cover plate detachably connected to the top of the base. A positioning mechanism 2 is pre-assembled inside the base. The positioning mechanism 2 is provided inside the housing 1, and an abutment 3 is provided inside the positioning mechanism 2. Mounting holes are provided on the side wall and bottom of the housing 1, and mounting covers 4 are fixedly installed in the mounting holes to adapt to the pipe connections of different pump bodies. A positioning hole 5 is provided on the top of the housing 1 for installing the housing 1 inside the washing machine. A water pumping device 6 is installed inside the housing 1 to drive the water flow. The water pumping device 6 adopts a common drain pump for washing machines. The positioning mechanism 2 is used to drive the abutment 3 to perform centering movement.

[0042] The positioning mechanism 2 drives the contact element 3 to move in the center, thereby fixing the pipeline and improving the stability of the pipeline during the pumping process. When the pipeline shakes, the contact element 3 cancels out the vibration force generated by the shaking, making the entire housing 1 more stable in the equipment.

[0043] Reference Figures 3-5 The positioning mechanism 2 includes a rotating rod 21 rotatably connected to the side wall of the housing 1. A knob 22 is fixedly connected to one end of the rotating rod 21 located on the outer wall of the housing 1, and the knob 22 fits against the outer wall of the housing 1. A bevel gear 23 is fixedly connected to one end of the rotating rod 21 located inside the housing 1. A fixed plate 24 is rotatably connected to the outer wall of the rotating rod 21 via a bearing. A bevel gear 25 is meshed with the side of the bevel gear 23 away from the rotating rod 21. A rotating rod 26 is fixedly passed through the middle of the upper end of the bevel gear 25. The rotating rod 21 and the rotating rod 26 are perpendicular to each other. The lower half of the outer wall of the rotating rod 26 is fixedly connected to a limiting ring 27. The lower end of the rotating rod 26 is fixedly connected to a threaded rod 28. The lower half of the outer wall of the rotating rod 26 is movably connected to a positioning frame 29. The rotating rod 26 is rotatably connected to the positioning frame 29. The middle section of the outer wall of the threaded rod 28 is threaded through a moving block 210. A buffer assembly is provided at the bottom of the moving block 210. The bottom of the fixed plate 24 is fixedly connected to the top of the positioning frame 29. The limiting ring 27 is symmetrically arranged on the outer wall and the inner wall of the positioning frame 29. The vertical direction of the rotating rod 26 and the threaded rod 28 is limited by the limiting ring 27.

[0044] When the operator rotates knob 22, knob 22 will drive rotating rod 21 to rotate, rotating rod 21 will drive bevel gear 23 to rotate, bevel gear 23 will drive bevel gear 25 to rotate, bevel gear 25 will drive rotating rod 26 to rotate, rotating rod 26 will drive threaded rod 28 to rotate, threaded rod 28 will drive moving block 210 to move vertically, and moving block 210 will drive the buffer assembly to fit against the outer wall of the pipe.

[0045] Reference Figure 6 The buffer assembly includes a sliding post 211 fixedly connected to the bottom of the movable block 210. A sliding plate 212 is slidably connected inside the cavity of the sliding post 211. A damping element 213 is fixedly connected to the top end of the sliding plate 212 away from the contact member 3. A spring 214 is sleeved on the outer wall of the damping element 213. A sliding rod 215 is fixedly connected to the end of the sliding plate 212 away from the damping element 213. The end of the sliding rod 215 away from the sliding plate 212 is fixedly connected to the top of the contact member 3. A linkage assembly is provided on the side wall of the movable block 210. The movable end of the damping element 213 is connected to the movable block. 210 is fixedly connected to the bottom. The damping component 213 is a friction damping sleeve. It generates a small displacement between the inner and outer cylinders, thereby directly and efficiently converting harmful structural vibration energy into heat energy and dissipating it. The spring 214 is made of spiral steel and is used to provide the main static support force. The two are set in parallel to perform shock absorption and buffering. The end of the spring 214 near the moving block 210 is fixedly connected to the bottom of the moving block 210. The sliding rod 215 is rotatably connected to the inside of the positioning frame 29. The bottom of the lower end of the positioning frame 29 is fixedly connected to the bottom plane of the inner wall of the housing 1.

[0046] When the moving block 210 moves downward, it will drive the sliding column 211 to move vertically downward. The sliding column 211 will drive the sliding rod 215 to move downward. The sliding rod 215 will drive the contact member 3 to fit against the outer wall of the pipe. As the sliding column 211 continues to move downward, the sliding rod 215 will drive the sliding piece 212 to slide vertically inside the sliding column 211, thereby compressing the damping member 213 and the spring 214, thus damping the vibration transmitted by the pipe through the contact member 3, thereby reducing the vibration of the pipe.

[0047] Reference Figure 7 , Figure 8 The linkage assembly includes a support 216 fixedly connected to the side wall of the movable block 210. A connecting rod 217 is rotatably connected to the movable end of the support 216. A support 218 is rotatably connected to the end of the connecting rod 217 away from the support 216 via a shaft. A sliding block 219 is fixedly connected to the mounting end of the support 218. A fixed rod 220 is horizontally movable through the side wall of the sliding block 219. The two ends of the fixed rod 220 are fixedly connected to the inner wall of the positioning frame 29. The positioning frame 29 is limited by the fixed rod 220, so that the sliding block 219 can only move horizontally. A vertical member 221 is fixedly connected to the lower end of the outer wall of the sliding block 219. A buffer assembly is disposed on the outer wall of the vertical member 221. The moving block 210 is symmetrically disposed inside the positioning frame 29. The middle of the moving block 210 located at the lower end of the positioning frame 29 is movably connected through a limiting rod 222. A spring 223 is sleeved on the outer wall of the limiting rod 222. The upper and lower ends of the limiting rod 222 are fixed to the inside of the positioning frame 29. The end of the spring 223 near the moving block 210 is fixedly connected to the bottom of the moving block 210. A positioning pin 224 is slidably connected to the side wall of the housing 1. The side wall of the positioning pin 224 fits into the groove of the side wall of the knob 22, so that when the positioning pin 224 is connected to the housing 1, the knob 22 is rotated and limited.

[0048] When the moving block 210 moves downward, it will drive the support 216 to move vertically downward. The support 216 will pull the connecting rod 217, which will drive the sliding block 219 to move horizontally. The sliding block 219 will drive the vertical member 221 to move horizontally in sync, so that the vertical member 221 drives the contact member 3 to fit against the outer wall of the pipe. The vertical member 221 drives the lower sliding block 219 to move synchronously, so that the contact member 3 located at the bottom of the pipe fits against the outer wall of the pipe. The contact member 3 is reset by the spring 223, and then the knob 22 is rotated and limited by the positioning pin 224.

[0049] The implementation principle of a water pump box for a washing machine in this application embodiment is as follows:

[0050] The positioning mechanism 2 drives the contact element 3 to move in the center, thereby fixing the pipeline and improving the stability of the pipeline during the pumping process. When the pipeline shakes, the contact element 3 cancels out the vibration force generated by the shaking, making the entire housing 1 more stable in the equipment.

[0051] When the operator rotates knob 22, knob 22 causes movable block 210 to move vertically. Movable block 210 causes buffer assembly to fit against the outer wall of the pipe. When movable block 210 moves downward, it causes sliding column 211 to move vertically downward. Sliding column 211 causes sliding rod 215 to move downward. Sliding rod 215 causes contact member 3 to fit against the outer wall of the pipe. As sliding column 211 continues to move downward, sliding rod 215 causes sliding piece 212 to slide vertically inside sliding column 211, thereby compressing damping member 213 and spring 214, thus compressing the pipe as it passes through the contact member. 3. The vibration transmitted is damped, thereby reducing the vibration of the pipeline. When the moving block 210 moves downward, the moving block 210 will drive the support 216 to move vertically downward. The support 216 will drive the sliding block 219 to move horizontally. The sliding block 219 will drive the vertical member 221 to move horizontally in sync, so that the vertical member 221 drives the contact member 3 to fit against the outer wall of the pipeline. The vertical member 221 drives the lower sliding block 219 to move synchronously, so that the contact member 3 located at the bottom of the pipeline fits against the outer wall of the pipeline. The contact member 3 is reset by the spring 223. Then, the knob 22 is rotated and limited by the positioning pin 224.
