Description

Technical Field

[0001] This utility model relates to a mobile tool for household appliances, and more particularly to a universal mobile base suitable for household appliances. Background Technology

[0002] Currently, household appliances such as washing machines, freezers, and refrigerators are inconvenient to move or time-consuming to move due to their large size and weight. To solve the problem of moving large household appliances such as washing machines, there are currently two main types of washing machine moving bases on the market. One type is a concealed washing machine moving base that is fixed together with the machine's mounting bolts. The drawback of this type is that different brands and models of washing machines require a different type of moving base to match, even if the mounting bolt positions are different. This results in high mold costs and a large number of corresponding part numbers for brand manufacturers, which is not conducive to product management, warehousing, and sales. Another type of movable washing machine base is not fixed to the washing machine's mounting bolts. It is inserted into the bottom of the washing machine when needed and pulled out and stored away after use. Its drawback is that raising the rollers requires turning the handle horizontally. Because the base is not fixed to the washing machine's mounting bolts, turning the handle causes the entire base to rotate, making it difficult to raise the rollers. A lot of force is needed to push the base against the front panel of the washing machine to turn the handle, which is inconvenient. Furthermore, the handle connection is prone to deformation under stress, affecting the product's lifespan. On the other hand, if this type of movable washing machine base were fixed to the mounting bolts, it would require designing specific movable washing machine bases for different brands and models of washing machines, which would be detrimental to product management, warehousing, and sales.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, this utility model discloses a universal movable base suitable for household appliances, including an outer groove plate 1, an inner groove plate 2, a front hinge seat 3, a front connecting shaft 4, a connecting rod 5, a wrench 6, a rear connecting shaft 7, a rear hinge seat 8, a rear hinge shaft 15, a left lifting plate 9, a right lifting plate 10, movable wheels 11, a left connecting shaft 12, a right connecting shaft 13, and a central shaft 14. The outer groove plate 1 supports the household appliance and has a U-shaped cross-section. During use, the household appliance is placed directly on the outer groove plate 1 without bolt fixing. The inner groove plate 2 has a U-shaped cross-section and is located inside the outer groove plate 1. The inner groove plate 2 can slide relative to the outer groove plate 1. A wrench assembly is connected to the end of the inner groove plate 2, which drives the inner groove plate 2 to slide relative to the outer groove plate 1. Multiple movable components are evenly distributed along the outer and inner groove plates. These movable components are used to lift the household appliance, causing its feet to leave the ground, allowing the appliance to be moved.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the wrench assembly includes a front hinge seat 3, a front connecting shaft 4, a connecting rod 5, a wrench 6, a rear connecting shaft 7, and a rear hinge seat 8. The front hinge seat 3 is located on the inner wall of the inner groove plate. The front end of the connecting rod 5 is hinged to the front hinge seat 3 via the front connecting shaft 4, and the rear end of the connecting rod 5 is hinged to the wrench 6 via the rear connecting shaft 7. The rear hinge seat 8 is located on the outer wall of the outer groove plate 1. The outer groove plate 1 has a slot 101. The wrench 6 passes through the slot 101 of the outer groove plate and is hinged to the rear end of the connecting rod 5. The wrench 6 is hinged to the rear hinge seat 8 via the rear hinge shaft 15. Rotating the wrench 6 vertically, i.e., rotating the wrench 6 up and down, causes the inner groove plate 2 to move along the outer groove plate 1 via the connecting rod 5. The rear hinge seat 8 includes a flat part 801 connected to the outer groove plate 1 and a U-shaped blocking part. The blocking part prevents the handle from hitting household appliances when moving upwards, thus providing a certain limiting function.

[0024] The moving assembly includes a left lifting plate 9, a right lifting plate 10, a moving wheel 11, a left connecting shaft 12, a right connecting shaft 13, and a central shaft 14. The left end of the left lifting plate 9 is hinged to the two side walls of the outer groove plate 1 through the left connecting shaft 12, and the left lifting plate 9 can rotate around the left connecting shaft 12. When the inner groove plate 2 moves along the outer groove plate 1, the left connecting shaft 12 remains stationary. The inner groove plate 2 is provided with a clearance groove 201, which is used to avoid the left connecting shaft 12. The right end of the right lifting plate 10 is hinged to the two side walls of the inner groove plate 2 via the right connecting shaft 13, and the right lifting plate 10 can rotate around the right connecting shaft 13. The right lifting plate 10 can slide together with the inner groove plate 2. When the inner groove plate moves along the outer groove plate, the right connecting shaft 13 moves together with the inner groove plate. The two side walls of the outer groove plate 1 are provided with travel grooves 102, which are used to prevent the right connecting shaft 13 from moving. The travel grooves 102 have arc-shaped notches 103 that serve as limiters. When the right connecting shaft 13 moves to the arc-shaped notch 103 of the travel groove 102, the arc-shaped notch 103 limits the right connecting shaft 13, so that the right lifting plate 10 is in an arched state. The right end of the left lifting plate 9, the left end of the right lifting plate 10, and the moving wheel 11 are mounted on the same central shaft 14. The right end of the left lifting plate, the left end of the right lifting plate, and the moving wheel are coaxially hinged. When the wrench assembly is rotated vertically, the inner groove plate 2 slides relative to the outer groove plate 1, causing the right lifting plate 10 to move to the left. The left lifting plate 9 and the right lifting plate 10 simultaneously arch upward to lift the moving wheel 11.

[0025] The working principle of this utility model is as follows: when it is necessary to move a household appliance, place the movable base directly on the bottom of the appliance, and pull the lever vertically, that is, pull the lever downward, which causes the inner groove plate to slide out relative to the outer groove plate, causing the right lifting plate to move to the left. At the same time, the left and right lifting plates arch downward to lift the moving wheels. The extended moving wheels contact the ground, and the outer surface of the bottom plate of the outer groove plate contacts the bottom of the household appliance. At the same time, the feet of the household appliance are lifted off the ground, making it easy to move the household appliance.
