Abstract
Description
Technical Field
[0001] The utility model relates to the field of counterweight blocks, in particular to a noise-reducing counterweight block for a washing machine. Background Art
[0002] There are counterweights inside the washing machine to give it a certain weight, which is used to reduce the vibration and shaking of the washing machine during operation and ensure its stability and balance. However, the washing machine will inevitably make noise during operation. When the washing machine is running, due to the collision between the washing drum and the outer shell of the machine body, a banging sound will be made;
[0003] In the prior art, the invention patent with publication number: CN 107556033 A proposes a noise reduction counterweight for washing machines, which is characterized in that, by weight, 10 parts of cement mortar, 0.5 parts of gypsum mortar, 10 parts of scrap metal particles, and 1 part of foaming agent are uniformly stirred and heated at a temperature of 50-270°C for 30 minutes, and poured into a mold, and the result is obtained after cooling and solidification; however, the counterweight is an integrated design and does not have the ability to be disassembled and assembled. After the counterweight is damaged, it needs to be replaced as a whole, which is costly and troublesome to maintain; at the same time, it does not have the ability to change the quality of the counterweight. When there is a matching deviation between the counterweight and the washing machine, its quality cannot be effectively adjusted and improved, which easily leads to a large noise in the later stage of the washing machine. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1 As shown in FIG. 4 , the present embodiment provides a noise reduction counterweight block for a washing machine, including a device body 1, wherein the device body 1 includes an upper shell 2, a lower shell 3 and an outer baffle 14, a center hole 4 is provided in the middle of the upper shell 2 and the lower shell 3, a plurality of positioning holes 5 are provided in the outer circle of the center hole 4, three groups of mounting holes 6 are provided in an annular array on the upper shell 2 and the lower shell 3, a filling port 10 is provided on one side of the upper shell 2 and the lower shell 3, and the two groups of filling ports 10 are symmetrically fitted, and a plurality of positioning holes 5 are provided inside the upper shell 2. A positioning sleeve 11 is provided, and a plurality of positioning columns 12 are provided inside the lower shell body 3, and the positioning columns 12 are correspondingly plugged into the positioning sleeve 11. A sealing plug 15 is provided on one side of the outer baffle plate 14, and the sealing plug 15 is plugged into the filling port 10. A movable groove 16 is provided inside the outer baffle plate 14, and a spring 17 is provided in the middle of the movable groove 16. The upper and lower ends of the spring 17 are connected to fixed columns 18, and a pushing block 19 is provided on the outer side of the fixed column 18. Fixed holes 20 are symmetrically opened on the upper shell body 2 and the lower shell body 3, and the fixed columns 18 are correspondingly plugged into the fixed holes 20.
[0024] Preferably, the mounting hole 6 is in a straight line structure, and the upper shell 2 and the lower shell 3 are both provided with an embedded groove 61 on the mounting hole 6. The embedded groove 61 facilitates hiding the bolts, and the straight line mounting hole 6 facilitates flexible adjustment of the mounting position. The center hole 4, the positioning hole 5 and the mounting hole 6 are all provided with a separation sleeve 7, and the upper and lower sets of separation sleeves 7 correspond to each other. The separation sleeve 7 facilitates shielding the poured cement to prevent it from extending into the hole.
[0025] Preferably, an upper sealing ring 9 is provided at the lower end of the upper shell 2, and a lower sealing ring 8 is provided at the upper end of the lower shell 3, and the lower sealing ring 8 corresponds to the upper sealing ring 9. The cooperation of the two sets of sealing rings facilitates the sealing and splicing of the upper shell 2 and the lower shell 3. A filling plate 13 is detachably installed inside the upper shell 2 and the lower shell 3, and a plurality of avoidance holes 131 are opened on the filling plate 13. The filling plate 13 made of foam material and the avoidance holes 131 can be used to adjust the amount of cement poured inside, so as to improve the overall quality and sound insulation effect of the counterweight block.
[0026] The use principle and use process of the utility model are as follows: when in use, firstly, the upper shell 2 and the lower shell 3 are correspondingly plugged in through the positioning sleeve 11 and the positioning column 12, so that the upper sealing ring 9 and the lower sealing ring 8 are correspondingly plugged in, and then cement is poured into the inside of the device through the filling port 10, and after the cement is dried, an outer baffle 14 is added to the filling port 10, so that the sealing plug 15 is filled in the filling port 10, and then the two groups of pushing blocks 19 are pressed, and the inner fixed column 18 is driven to shrink by the pushing blocks 19, and the fixed column 18 squeezes the spring 17 to shrink. At this time, the two groups of fixed columns 18 are placed in the movable groove 16, and then the outer baffle 14 is attached to the filling port 10. The two ends of the movable groove 16 correspond between the upper and lower groups of fixing holes 20. At this time, the push block 19 is released, the spring 17 elastically resets and pushes the two groups of fixing columns 18 to elastically expand and contract, so that the fixing columns 18 are clamped in the fixing holes 20. At this time, the internal sealing of the device is completed, which can effectively prevent water vapor from entering the cement block and causing its weight to change. When different mass counterweights are needed, filling plates 13 can be added inside the upper shell 2 and the lower shell 3, and then they are spliced and poured with cement, which can effectively improve the cement filling amount, change the counterweight of the device, and improve the sound insulation effect of the device, effectively increasing the practicability of the device.
