Description

Technical Field

[0001] This utility model relates to a mobile stand for household appliances, and more particularly to a mobile stand with an anti-fall-back function. Background Technology

[0002] Currently, household appliances such as washing machines, freezers, and refrigerators are inconvenient to move or require considerable time and effort due to their large size and weight. To address the issue of moving large household appliances such as washing machines, the applicant previously applied for a ramp-type moving bracket (CN217995582U). In use, when the appliance needs to be moved, the lever is rotated 90 degrees, causing the second groove plate to slide out relative to the first groove plate. The moving wheels then move and rise relative to the ramp surface, contacting the ground. The outer surface of the bottom plate of the first groove plate contacts the bottom of the appliance. Simultaneously, the appliance's feet are lifted off the ground, facilitating its movement. However, during use, it was found that when the casters are raised, they often fall back down and cannot be locked in the raised state; this can easily cause safety hazards, such as falling down and pressing on hands or feet; during the movement of household appliances, the casters may fall back down, causing the appliances to tip over, mainly because the casters fall back down and cause the appliances to stop suddenly, the feet of the appliances touch the ground, the appliances cannot be moved, or the appliances tip over due to inertia.

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

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, this utility model discloses a movable bracket with an anti-fall-back function, including an outer slot plate 1, an inner slot plate 2, and movable components. The outer slot plate 1 has a U-shaped cross-section and is provided with a rear slot for connecting to the rear feet of a household appliance, a front slot for connecting to the front feet of the household appliance, and connecting nuts fixed on the front and rear slots. The connecting nuts can be the original nuts of the household appliance. During use, the front feet of the household appliance are inserted into the front slot, and the rear feet are inserted into the rear slot, and are respectively fixed and tightened by the connecting nuts. The inner slot plate 2 has a U-shaped cross-section and is located inside the outer slot plate 1. The inner slot plate 2 can slide relative to the outer slot plate 1. A wrench assembly is connected to the end of the inner slot plate 2. The wrench assembly drives the inner slot plate 2 to slide relative to the outer slot plate 1. Multiple movable components are evenly distributed along the outer and inner slot plates. The movable components are used to lift the household appliance, so that the feet of the household appliance are off the ground, and then the household appliance can be moved.

[0027] like Figure 6As shown, the inner bottom surface of the outer groove plate 1 is fitted with the outer bottom surface of the inner groove plate 2. The inner bottom surface of the outer groove plate 1 has a protrusion 3, which can be integrally formed from the outer groove plate 1 or a rivet. A stop surface 4 is provided on the bottom surface of the inner groove plate 1 to stop the protrusion 3. Pulling the inner groove plate 2 causes it to slide relative to the outer groove plate 1, lifting the moving component. The protrusion 3 contacts the stop surface 4 to prevent the moving component from falling back. In one embodiment, a first groove 5 is provided on the outer bottom surface of the inner groove plate 2, with the groove edge forming the stop surface 4. The first groove 5 can be integrally formed from the inner groove plate 2. In some embodiments, the inner groove plate 2 has a reinforcing rib 6, which is integrally formed by extending upward from the outer bottom surface of the inner groove plate 2 and forming a first groove 5 on the corresponding outer bottom surface of the inner groove plate 2. The setting of the first groove 5 of this utility model utilizes the space formed on the corresponding outer bottom surface of the inner groove plate 2 by the integrally formed reinforcing rib 6, which saves manufacturing processes and further improves the performance of the mobile support.

[0028] like Figure 4 As shown, in some embodiments, the rear edge 7 of the bottom surface of the inner groove plate 2 forms a stop surface 4, which, with the existing structure of the inner groove plate and the protrusion, prevents the moving component from falling back.

[0029] like Figure 5 As shown, in some embodiments, the side edge of the wrench 16 of the wrench assembly forms a stop surface 4, which, using the original wrench structure and in conjunction with the protrusion, prevents the moving component from falling back.

[0030] like Figure 3 and Figure 4 As shown, in some embodiments, a through hole 8 is provided on the bottom surface of the inner groove plate 2. The groove edge of the through hole 8 forms a stop surface 4. The groove edge of the through hole, together with the protrusion, prevents the moving component from falling back. The through hole 8 can be a round hole, a square hole, a U-shaped hole, an elliptical hole, or a triangular hole, etc.

[0031] In some embodiments, a second groove 9 for accommodating the protrusion 3 is also provided on the outer bottom surface of the inner groove plate 2. In the initial state, the protrusion 3 is located in the second groove 9. Alternatively, in some embodiments, a second through hole for accommodating the protrusion 3 is also provided on the outer bottom surface of the inner groove plate 1. In the initial state, the protrusion 3 is located in the second through hole. This ensures that in the initial state, the inner bottom surface of the outer groove plate and the outer bottom surface of the inner groove plate 2 can fit tightly together, thus ensuring the stability of the movable support.

[0032] like Figure 5 , Figure 7 and Figure 8As shown, the moving assembly includes a connecting plate 10, a moving wheel 11, a ramp block 12, and a connecting shaft 13. One end of the connecting plate 10 is hinged to the two side walls of the outer groove plate 1 via the connecting shaft 13. Both ends of the connecting shaft 13 pass through the inner groove plate 2, and the connecting plate 10 can rotate around the connecting shaft 13. The moving wheel 11 is located at the other end of the connecting plate 10, and the ramp block 12 is located on the inner groove plate 2. The inner groove plate 2 has a connecting groove 14 for avoiding the connecting shaft 13. The tail end of the connecting groove 14, facing the direction of the moving wheel's extension, has an anti-fall groove 15. Figure 9 As shown; in the initial state, the moving wheel 11 is located at the lower part of the slope of the ramp block 12; when the inner groove plate 2 is pulled, the inner groove plate 2 slides relative to the outer groove plate 1, and the ramp block 12 moves together with the inner groove plate 2. The moving wheel 11 moves from the lower part to the higher part of the slope of the ramp block 12 and is lifted. The connecting shaft 13 falls into the anti-fall groove 15, which prevents the connecting shaft 13 from moving back and prevents the moving wheel from falling back. The ramp block 12 is integrally formed by extending upward from the outer bottom surface of the inner groove plate 2, and a second groove 9 is formed on the corresponding outer bottom surface of the inner groove plate 2. The second groove 9 can accommodate the protrusion 3 in the initial state, ensuring that the inner bottom surface of the outer groove plate and the outer bottom surface of the inner groove plate 2 can fit tightly in the initial state, ensuring the stability of the moving support.
