[0038] Example

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, this embodiment provides a transfer device, including a bracket 10 and a wheel frame 20, the front part of the top surface of the bracket 10 is provided with a placement groove 11, the rear part of the bracket 10 is provided with a plurality of mounting holes 12, and the bottom surface of the bracket 10 is provided with a slide 13; the wheel frame 20 is arranged in the slide 13, and the wheel frame 20 is provided with at least one wheel unit 21 and a driving rod 30 that drives the wheel frame 20 to slide and pushes out or retracts the wheel unit 21, and the driving rod 30 is arranged at the front part of the wheel frame 20.

[0040] During manufacturing, the transfer device can be installed on the bottom surface of the home appliance and used when it needs to be moved, so that manual transportation can be carried out more easily; the dedicated or adapted design will not cause damage to the home appliance during transportation, and also protects the transporters from accidental injuries.

[0041] Specifically, the transfer device can be adapted for use with a washing machine. The mounting hole 12 is designed to allow for the installation of legs and / or power cords, etc., through the mounting hole 12. The placement slot 11 accommodates the transverse protrusion on the front bottom of the washing machine, and is secured with bolts to achieve a secure installation. Subsequently, the drive rod 30 drives the wheel frame 20 to slide along the slide 13, causing the wheel unit 21 to extend and lift the washing machine on the bracket 10. This allows the appliance to be easily moved and stored on the bottom surface of the washing machine. This provides excellent practicality and prevents damage to the appliance.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the drive rod 30 has a rotating shaft 301 hingedly mounted at the front end of the wheel frame 20. The drive rod 30 is provided with a positioning rod 302 eccentrically disposed relative to the rotating shaft 301. The front portion of the wheel frame 20 is provided with a strip-shaped hole 22 that slidably engages with the positioning rod, i.e., it is driven by a cam structure. Thus, when the drive rod 30 is moved, the positioning rod 302 rotates about the rotating shaft 301, and the strip-shaped hole 22 in the front portion of the wheel frame 20 securely engages with the positioning rod, allowing the wheel frame 20 to slide along the slideway 13, thereby lowering or extending the wheel assembly unit 21 from the wheel frame 20, thereby effectively retracting and extending the wheel assembly unit 21.

[0043] Furthermore, if Figure 5 、 Figure 6 and Figure 7 As shown, in this embodiment, the wheel assembly unit 21 includes a roller 211, and a fixed rocker arm 212 and a sliding rocker arm 213, one end of which is rotatably arranged on the wheel axle of the roller 211, the other end of the fixed rocker arm 212 is hingedly provided with a first fixed rod 214, and the other end of the sliding rocker arm 213 is hingedly provided with a second fixed rod 215; the first fixed rod 214 is arranged on the bracket 10, and the wheel frame 20 is provided with a first sliding groove 23 for sliding of the first fixed rod 214; the second fixed rod 215 is arranged on the wheel frame 20, and the bracket 10 is provided with a second sliding groove 14 for sliding of the second fixed rod 215.

[0044] When the driving rod 30 is rotated, causing the wheel frame 20 to move forward along the slideway 13 of the bracket 10, the first fixing rod 214 fixed to the bracket 10 does not move, while the second fixing rod 215 slides along the second slideway 14 with the wheel frame 20. In this way, the fixed rocker 212 and the sliding rocker 213 clamp and push the roller 211 out of the wheel frame 20 for use. Conversely, when the driving rod 30 is rotated in the opposite direction, the fixed rocker 212 and the sliding rocker 213 are stretched into a straight line (i.e., the first fixing rod 214 and the second fixing rod 215 are moved away from each other), and the roller 211 is stored in the wheel frame 20, thereby forming an "L" shape with the bracket 10, so that it can be hidden in the bottom surface of the home appliance without affecting the normal use of the home appliance, thereby improving its practicality.

[0045] Furthermore, if Figure 5 、 Figure 6 and Figure 7As shown, in this embodiment, the wheel assembly unit 21 also includes a third fixed rod 216 arranged on the wheel frame 20 and in contact with the top surface of the fixed rocker arm 212, and a third sliding groove 15 is provided on the bracket 10 for the third fixed rod 216 to slide; the top surface of the fixed rocker arm 212 is provided with a first limiting groove 2121 and a second limiting groove 2122 that are engaged with or separated from the third fixed rod 216, and the fixed rocker arm 212 is provided with a raised arc surface 2123 between the first limiting groove 2121 and the second limiting groove 2122. The first limiting groove 2121 is provided on the fixed rocker arm 212 on the side close to the roller 211, and the second limiting groove 2122 is provided on the fixed rocker arm 212 on the side close to the first fixed rod 214.

[0046] Specifically, the third fixing rod 216 is located between the first fixing rod 214 and the second fixing rod 215, and is designed to abut against the fixed rocker 212. When the driving rod 30 is rotated to move the wheel frame 20 toward the front along the slideway 13 of the bracket 10, the third fixing rod 216 moves synchronously with the second fixing rod 215. During the movement process, the distance between the second fixing rod 215 and the first fixing rod 214 gradually decreases, and the third fixing rod 216 moves from the first limiting groove 2121 to the second limiting groove 2122. During the movement process, the third fixing rod 216 moves along the raised arc surface 2123, pressing the fixed rocker 212 outward, causing the fixed rocker 212 to swing outward, thereby easily ejecting the roller 211 from the wheel frame 20. The engagement of the third fixing rod 216 with the second limiting groove 2122 also improves the stability of the structure.

[0047] In this embodiment, the arc length of the sliding rocker 213 driving the roller 211 to swing is equal to the length of the first chute 23. Therefore, when the roller 211 is fully extended, the sliding rocker 213 and the roller 211 are vertically supported, ensuring a stable support force for the roller 211 after it is extended from the wheel frame 20, thereby improving safety. Furthermore, the first chute 23, the second chute 14, and the third chute 15 are configured with the same length, allowing the first fixed rod 214, the second fixed rod 215, and the third fixed rod 216 to move synchronously, ensuring smooth structural coordination.

[0048] In this embodiment, the depth of the placement groove 11 is greater than the diameter of the roller 211, and the depth of the placement groove 11 is greater than or equal to the height of the wheel frame 20. Therefore, when stored, the roller 211 can be completely stored in the wheel frame 20, achieving the purpose of hiding the roller 211. At the same time, the size of the installation itself can be reduced so that it can be installed on the bottom surface of the home appliance, which has good practicality.

[0049] like Figure 1As shown, in this embodiment, the bracket 10 is located at the placement slot 11 and is provided with a first leg locking hole 16 side by side. The support leg can be installed on the bottom surface of the home appliance through the first leg locking hole 16, which meets the installation requirements of the leg. At the same time, the transfer device can be locked and installed through the leg.

[0050] Furthermore, in this embodiment, the plurality of mounting holes 12 include a second leg locking hole 121, at least one auxiliary fixing hole 122, and a power cord avoidance hole 123 arranged side by side. Similarly, the second leg locking hole 121 can be used to install a leg at another location. The auxiliary fixing hole 122 can form a through hole required for bolt locking, or serve as an avoidance hole for home appliances; and the design of the power cord avoidance hole 123 facilitates the routing of the power cord of the home appliance, forming an avoidance design purpose at a primary location to adapt to the installation requirements between the home appliance and the transfer device, avoiding damage to the bottom of the home appliance, and having good practicality.

[0051] like Figure 1 As shown, in this embodiment, the second leg locking hole 121, the auxiliary fixing hole 122 and the power cord avoidance hole 123 are long holes, which can improve adaptability and have a higher fault tolerance rate, making it easier to install home appliances.

[0052] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
