Description

Technical Field

[0001] The utility model relates to the technical field of washing machine bases, in particular to a washing machine chassis assembly. Background Art

[0002] Washing machine pan assemblies are plastic support components designed specifically for washing machines and are manufactured using an injection molding process. This base is often used to raise the height of the washing machine, make it more stable, facilitate cleaning or maintenance, and help prevent ground moisture from damaging the bottom of the washing machine. These components are designed with non-slip feet or wheels to make them easy to move while ensuring the machine is quiet and stable during use. They are usually made of durable plastic or rubber that can withstand the weight of the washing machine and adapt to various floor surfaces.

[0003] An existing Chinese patent (publication number: CN218951763U) proposes a washing machine base, including: an angle seat body, four of which are arranged in a rectangular shape; a fixed suction cup is provided at the lower end of the angle seat body; an adjustment structure, four of which are provided, and the adjustment structure connects two adjacent angle seats, the adjustment structure includes an adjusting screw, a fixed seat and a threaded seat, the fixed seat and the threaded seat are respectively fixed to the two angle seats, the adjusting screw is rotatably connected to the fixed seat, and the adjusting screw is threadedly connected to the threaded seat.

[0004] The above technical solution adjusts the distance between the base bodies by turning the screw, so that it can adapt to washing machines of different sizes and specifications, thereby enhancing the practicality of the base. However, since the washing machine body is too heavy, it is inconvenient to move the washing machine for families with limited space or who need to frequently adjust the room layout. The washing machine cannot be moved in the chassis assembly of the above device, and a movable base is generally installed at the bottom of the existing washing machine. However, the washing machine will vibrate when it is running, which can easily cause the base to shake and cause the position of the washing machine to shift. Therefore, we propose a washing machine chassis assembly. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-2 As shown, a washing machine chassis assembly includes a washing machine base frame 1, a universal wheel 2 is arranged at the bottom of the washing machine base frame 1, a lifting assembly 3 is arranged on one side of the washing machine base frame 1, and the lifting assembly 3 includes a bracket plate 31, the bracket plate 31 is fixed on the washing machine base frame 1, a square groove 7 is opened at the bottom of the bracket plate 31, a tooth plate 32 is slidably connected in the bracket plate 31, a first rotating shaft 33 is rotatably connected to the side of the bracket plate 31 close to the tooth plate 32, a gear 34 is arranged on the first rotating shaft 33, the gear 34 is meshed with the tooth plate 32, a sleeve 35 is sleeved on the gear 34, a handle 36 is arranged in the sleeve 35, the handle 36 is fixedly connected to the gear 34, and a connecting rod is fixedly connected to the bottom of the tooth plate 32 8. A support plate 9 is provided on one side of the washing machine base frame 1 near the connecting rod 8. The connecting rod 8 is slidably connected to the support plate 9. Two lifting assemblies 3 are provided, and the two lifting assemblies 3 are respectively located on both sides of the washing machine base frame 1. Four supporting feet 6 are provided and are respectively located at the four corners of the bottom of the washing machine base frame 1. The washing machine can be moved by the universal wheels 2. When the washing machine does not need to be moved, the lifting assembly 3 is provided to rotate the handle 36 to drive the gear 34 to rotate, and the gear 34 drives the tooth plate 32 to slide and rise in the square groove 7. The tooth plate 32 drives the bottom supporting feet 6 to fix the washing machine to prevent the vibration generated when the washing machine is running from causing the washing machine to shake and shift in position;

[0027] Furthermore, Figure 2 As shown: the lifting assembly 3 also includes a second rotating shaft 37, which is rotatably connected to the inner wall of the bracket plate 31, and a torsion spring 38 is sleeved on the second rotating shaft 37. The torsion spring 38 is rotatably connected to a limiting member 39 on a side away from the second rotating shaft 37. By providing the torsion spring 38 and the limiting member 39, the tooth plate 32 can be prevented from being limited and fixed during the lifting operation;

[0028] The above solutions also have the problem that when the washing machine is running, vibration will be generated, which may easily cause the chassis assembly to be unstable and shake or even fall off. Figure 3As shown: a buffer assembly 5 is provided on the side of the connecting rod 8 away from the supporting plate 9, and the buffer assembly 5 includes a damper 51, a telescopic rod 52 is connected to the bottom of the damper 51, and a cross bar 10 is connected to the side of the telescopic rod 52 away from the damper 51, and a supporting foot 6 is provided at the bottom of the cross bar 10. By arranging the damper 51 and the telescopic rod 52, when the washing machine generates vibration during operation, a vibration reduction effect can be achieved;

[0029] In the above solution, there is still a problem that when the cross bar 10 and the bottom support foot 6 slide and rise, there is no auxiliary sliding, which may easily lead to insufficient sliding or even jamming. Figure 3 As shown: an auxiliary component 4 is provided on one side of the washing machine base frame 1 close to the cross bar 10, the auxiliary component 4 includes a slide rail 41, a screw 42 is threadedly connected to the slide rail 41, the screw 42 penetrates the slide rail 41 and is connected to the washing machine base frame 1, a slider 43 is slidably connected to the slide rail 41, and the side of the slider 43 away from the slide rail 41 is connected to the cross bar 10. By providing the auxiliary component 4, the lifting component 3 can be assisted to slide the cross bar 10 and the bottom support leg 6, so as to facilitate the bottom support leg 6 to be fixed on the ground;

[0030] There are two auxiliary components 4, which are respectively located on both sides of the washing machine base frame 1, and two sliders 43 are respectively connected to the two ends of the cross bar 10. The above arrangement enables the cross bar 10 and the supporting legs 6 to slide more smoothly.

[0031] Working principle: Figure 1 - Figure 4 As shown, the universal wheel 2 arranged at the bottom of the washing machine base frame 1 can be used to move the washing machine, which is very convenient for families with limited space or who need to frequently adjust the room layout. Since the washing machine will generate vibration when it is running, the universal wheel 2 will shake and drive the washing machine to shift. At this time, the lifting component 3 is set, and the handle 36 is rotated to drive the gear 34 to rotate. The gear 34 drives the tooth plate 32 to slide and rise in the square groove 7. The tooth plate 32 drives the bottom support foot 6 to fix the washing machine to prevent the position of the washing machine from shifting. The damper 51 and the telescopic rod 52 are set, and when the washing machine vibrates during operation, the vibration reduction effect can be achieved. When the cross bar 10 and the bottom support foot 6 slide and rise, there is no auxiliary sliding, which easily leads to insufficient sliding or even jamming. By setting the auxiliary component 4, the lifting component 3 can be assisted to slide the cross bar 10 and the bottom support foot 6, so as to facilitate the fixing of the bottom support foot 6 on the ground.

[0032] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
