Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a lifting and dragging base for a washing machine. Background Art

[0002] In a warehouse environment or a home use environment, there are two ways to move heavy household appliances (such as washing machines or refrigerators): using a transfer forklift and manual handling. In between the two methods, there is also a method of using a portable and easy-to-assemble lifting device to perform the transfer operation.

[0003] During use, the lifting device is inserted under the large household appliances, and the large household appliances are lifted up by operating the trailer. Further transfer of the large household appliances requires the cooperation of a trailer, but this method depends on the size of the site. If the space is relatively small, it is inconvenient to carry out trailer operations. In addition, considering user needs, it is sometimes necessary to change the position of household appliances (such as washing machines and refrigerators). At that time, it is inconvenient to find a lifting device and a trailer. Utility Model Content

Detailed implementation mode

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0026] The specific embodiments of the present utility model will be described below in conjunction with the drawings.

[0027] As Figures 1 to 7 shown, a lifting and dragging base of a washing machine includes a dragging bracket 1. The dragging bracket 1 includes a support member 2, a sliding member 3, a lever member 4 and a roller assembly 5. A chute 6 for the sliding member 3 to slide is provided on the support member 2. One end of the lever member 4 is hinged to the support member 2 and the lever member 4 is linked with the sliding member 3. When the lever member 4 rotates, it can drive the sliding member 3 to move along the length direction of the chute 6. The roller assembly 5 includes a lifting bracket 7 and a roller 8 rotatably installed on the lifting bracket 7. The lifting bracket 7 is hinged to the support member 2 and has a storage state in which at least part of it can be received in the chute 6 and a lifting state in which it can rotate relative to the support member 2 to move the roller 8 away from one end of the chute 6. The lifting bracket 7 has a guiding portion 9, and an inclined groove 10 or a guiding inclined surface 11 is formed on the guiding portion 9. The height of the inclined groove 10 or the guiding inclined surface 11 gradually decreases from the end where the lifting bracket 7 is hinged to the sliding member 3 to the end away from the sliding member 3. A guiding portion 12 that moves along the path of the inclined groove 10 or the guiding inclined surface 11 is fixedly or integrally provided on the sliding member 3.

[0028] When the lever member 4 is close to or perpendicular to the sliding member 3, the guiding portion 12 is located at the upper end of the inclined groove 10 or the guiding inclined surface 11. When the lever member 4 is close to or parallel to the sliding member 3, the guiding portion 12 is located at the lower end of the inclined groove 10 or the guiding inclined surface 11.

[0029] As Figure 2 shown, Embodiment 1: The lower end surface of the guiding portion 9 is a guiding inclined surface 11. The guiding inclined surface 11 and the bottom wall of the sliding member 3 form a movable area 13. The guiding portion 12 is a guiding rod or a guiding convex block, and the guiding portion 12 is placed in the movable area 13.

[0030] Two dragging brackets 1 are provided, and the two dragging brackets 1 are symmetrically arranged in structure at the bottom of the washing machine.

[0031] The lifting bracket 7 includes a lifting plate 14. The guiding portion 9 is formed by downward extension on both sides of the lifting plate 14. The two ends of the lifting plate 14 are respectively an installation end 15 of the roller 8 and a hinged end 16 that rotates and cooperates with the support member 2.

[0032] The slider 3 has a bottom plate 17 and two side plates 18. At least two long slots 19 penetrating the two side plates 18 are arranged at intervals along the length direction of the slider 3. The support member 2 is adapted to the shape of the slider 3 and the slider 3 is placed inside the support member 2. At least two sets of lifting brackets 7 are provided, and the lifting brackets 7 are rotatably connected to the support member 2 through a pin shaft 20. The positions of the long slots 19 correspond to those of the pin shaft 20, and the sliding plate will not interfere with the pin shaft 20 when moving.

[0033] Connection grooves 21 are provided at both ends of the support member 2. The connection grooves 21 are L-shaped and one end of the connection grooves 21 is provided with an opening 22. Bolts or support feet with external threads can be used. By loosening the bolts or support feet, the opening 22 of the connection groove 21 of the support member 2 can be aligned with the bolts or support feet and snapped in from the side without completely removing the bolts or support feet, making the operation more convenient.

[0034] One end of the lever 4 along the length direction is hinged to the support member 2 to form a first hinge point 23. A connecting rod linked with the slider 3 is arranged at a position of the lever 4 adjacent to the first hinge point 23. Both ends of the connecting rod are respectively hinged to the lever 4 and the slider 3 to form a second hinge point 24 and a third hinge point 25 at both ends.

[0035] Working principle: Install the towing base at the bottom of the washing machine. During use, operating the lever 4 can lift the rollers 8 downward so that they are higher than the support feet of the washing machine, facilitating the movement of the washing machine. The operation is convenient. Specifically: In the initial state, the lever 4 is perpendicular to the slider 3. At this time, the guiding portion 12 is located at the upper end (right end) of the inclined slot 10 or the guiding inclined surface 11. Operating the lever 4 outward makes it parallel to the slider 3. At this time, the guiding portion 12 is located at the lower end (left end) of the inclined slot 10 or the guiding inclined surface 11. When the guiding portion 12 moves from the upper end to the lower end (that is, when the lever 4 changes from the vertical state to the parallel state and the slider 3 moves from right to left), since the right end of the lifting bracket 7 is the hinged end 16, the lifting bracket 7 will gradually rotate outward to move the rollers 8 away from the sliding slot 6. The above-described structure is based on the case where the lever 4 is hinged to the left end of the support member 2. Similarly, the lever 4 can be arranged at the right end, and only the left-right relative position of the above structure needs to be changed. Embodiment

[0036] As Figure 8 shown, the difference between the second embodiment and the first embodiment is that: an inclined slot 10 is formed on the guiding portion 9 and the guiding portion 12 is a guiding rod, and the guiding portion 12 is fixed or integrally formed on the slider 3.
