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 manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0025] The specific embodiments of the present utility model will be described below in conjunction with the drawings.

[0026] As Figures 1 to 7 shown, a washing machine towing base includes two towing brackets 1. The towing bracket 1 includes a support member 2, a sliding member 3, a lever member 4 and a roller assembly 5. A chute 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. The roller assembly 5 has rollers 6 with adjustable longitudinal height, and the longitudinal height of the rollers 6 changes when the position of the sliding member 3 changes. Support feet (not shown in the figure) are respectively provided at one ends of the two support members 2 close to the lever member 4. The support members 2 are fixed to the washing machine through the support feet. The support feet are commercially available and adjustable. Connectors 7 are provided at the other ends of the two support members 2. Both ends of the connector 7 are respectively connected to the support members 2. A hydraulically interconnected foot 8 is provided on the connector 7. The hydraulically interconnected foot 8 includes two hydraulic feet 9 provided at both ends of the connector 7 and a connecting pipe 10 for conducting the internal hydraulic medium to flow between the two hydraulic feet 9. In this embodiment, the hydraulic feet 9 are commercially available, and their working principle has been disclosed in the prior art, so no specific description will be made. In addition to providing an installation position for the hydraulically interconnected foot 8, the connector 7 can also connect the two support members 2 into an installation component. Only by aligning the position of one support member 2, it can be installed on the washing machine.

[0027] The connector 7 is vertically installed between the two support members 2. A placement groove 11 is provided along the length direction of the connector 7. The connecting pipe 10 is located in the placement groove 11, and the installation height of the connecting pipe 10 is lower than the end face of the placement groove 11 or flush with the end face of the placement groove 11.

[0028] Both ends of the connector 7 have insertion portions 12. Insertion slots 13 for the insertion portions 12 to be inserted are provided at the ends of the support members 2. The hydraulic feet 9 are limited in the insertion slots 13. Two L-shaped baffles 14 are spaced apart at one ends of the two support members 2 for the connector 7 to be inserted. The slot 13 is formed between the two baffles 14. The width of the slot 13 is adapted to the width of the insertion portion 12. The insertion and matching method is not limited, and other forms such as snap connection or welding can also be adopted.

[0029] The plug-in portion 12 is provided with a plurality of first through holes 15 around the hydraulic support, and the support member 2 is provided with a plurality of second through holes 16 corresponding to the first through holes 15 , and the two are connected as a whole by bolts.

[0030] Connecting ears 17 are provided at both ends of the support member 2, and connecting holes 18 for installing supporting feet are opened on the connecting ears 17. The supporting foot (not shown in the figure) installed on the left connecting ear 17 is lower than the hydraulic supporting foot 9, and the supporting foot (not shown in the figure) installed on the right connecting ear 17 is matched with the height of the hydraulic supporting foot 9.

[0031] Two groups of roller assemblies 5 are provided on each sliding member 3, and the two groups of roller assemblies 5 are located on both sides of the sliding member 3. The roller assembly 5 includes a roller 6, a first swinging member 19, a second swinging member 20, a connecting pin 21, a rotating pin 22 and a movable pin 23. The roller 6 is sleeved on the connecting pin 21. The upper ends of the first swinging member 19 and the second swinging member 20 are rotatably connected by the connecting pin 21. The lower end of the first swinging member 19 is rotatably connected to the support member 2 by the rotating pin 22. The inner wall of the sliding member 3 is provided with a first sliding groove 24 or a clearance area corresponding to the position of the rotating pin 22 (that is, the sliding member 3 does not interfere with the rotating pin 22 when sliding). The first slide groove 24 or the yield area moves relative to the rotating pin 22, and the lower end of the second swinging member 20 is provided with a movable pin 23 that penetrates the sliding member 3. The side wall of the support member 2 is provided with a second slide groove 25 for the movable pin 23 to slide. The movable pin 23 extends into the second slide groove 25. When the pull member 4 is pulled outward, the lower end of the second swinging member 20 slides from the left to the right (the side of the connecting member 7 is defined as the left side, and the side of the pull member 4 is positioned as the right side). At this time, the longitudinal position of the roller 6 becomes higher. When the pull member 4 is adjusted from the parallel state to the vertical state, the lower end of the second swinging member 20 slides from the right to the left, and the longitudinal position of the roller 6 becomes lower.

[0032] One end of the pull member 4 along the length direction is hinged to the support member 2 to form a first hinge point 26. The pull member 4 and the movable member are linked by a connecting rod 27. The two ends of the connecting rod 27 are respectively hinged to the sliding member 3 and the pull member 4 to form a second hinge point 28 and a third hinge point 29. In this embodiment, the connecting rod 27 is arc-shaped. When the pull member 4 is parallel to the support member 2, the roller is higher than the hydraulic support foot 9 and the support foot. When the pull member 4 is perpendicular to the support member 2, the roller is lower than the hydraulic support foot 9 and the support foot.

[0033] Working principle: The traditional washing machine towing base does not have the function of automatically adjusting the height. When the ground is uneven, it is very troublesome to manually adjust the height of the four supporting feet. In this application, a connecting piece 7 and a hydraulically interconnected foot 8 are provided on the washing machine towing base. Through two hydraulic feet and a connecting pipe 10, the adaptive adjustment of the washing machine is realized according to the hydraulic principle, which can automatically level the height of one side without adjusting all the supporting feet. Especially in the scene of setting up a laundry cabinet, a lever 4 is provided on one side of the washing machine towing base. Usually, the right side (i.e., the outside) is open when the cabinet is set up to provide an operation space for the lever 4. However, when the washing machine is installed in the cabinet, the left side (i.e., the inside) cannot be manually adjusted. The hydraulically interconnected foot 8 provided on the left side in this application can just adaptively adjust.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and do not limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
