Description
Technical Field
[0001] This utility model relates to the field of white goods moving devices, specifically an adjustable movable bracket for refrigerators and washing machines. Background Technology
[0002] In recent years, with the continuous improvement of people's requirements for quality of life, integrated and large-capacity refrigerators and washing machines, such as drum washing machines with washer-dryer combos and large-capacity multi-door refrigerators, have been increasingly used. However, the weight and volume of these refrigerators and washing machines are constantly increasing with their functions and capacities, which makes it increasingly difficult to move and transport them during actual installation and use.
[0003] Currently, devices for facilitating the movement and transport of refrigerators and washing machines have also emerged in this field. For example, Chinese utility model patent CN214005161U discloses a portable washing machine trolley, which can be placed at the bottom of the washing machine and connected to the bottom of the washing machine through the first and second fixing holes. At the same time, the inner rail can be pulled out from the outer rail through the pull rod assembly, so that the wheels can be extended to facilitate the dragging of the washing machine. Although it can carry and move the washing machine, it has the problem of large overall structure, which is not convenient for the movers to carry. At the same time, since the positions of the first and second fixing holes on both sides are relatively fixed, it is often only suitable for moving and transporting washing machines with a single width dimension.
[0004] To address the aforementioned issues, separate movable supports have emerged in this field. For example, Chinese utility model patent CN217203262U discloses a hidden adjustable movable support for washing machines, which achieves a separate structure for easy carrying and application. However, in actual use, this separate movable support requires a significant external force to be applied to the handle to achieve the movement between its inner and outer tracks, making operation difficult. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides an adjustable movable bracket for refrigerators and washing machines, which solves the operational difficulties of existing handling and moving devices.
[0006] The technical solution is an adjustable movable bracket for refrigerators and washing machines, comprising an outer bracket, an inner bracket, a wheel assembly, and a drive component. The outer bracket directly supports and fixes the refrigerator and washing machine, and its bottom forms a longitudinally extending track cavity. The inner bracket is slidably disposed within the track cavity of the outer bracket. The outer and inner brackets are provided with mutually cooperating wheel state switching structures. The wheel assembly is movably mounted on the outer and inner brackets through the wheel state switching structures. The wheel assembly has a first state in contact with the ground and a state detached from the ground. In the second state, the driving component can drive the inner bracket and the outer bracket to form a relative longitudinal linear sliding. During this process, the wheel state switching structure drives the wheel assembly to switch between the first state and the second state. The driving component includes a handle and a driving link. The handle has a first connecting end and a second connecting end. The first connecting end and the second connecting end are set at an angle. The front end of the driving link is pivotally connected to the longitudinal rear end of the inner bracket, and the rear end is pivotally connected to the second connecting end of the handle. The first connecting end of the handle is pivotally connected to the longitudinal rear end of the outer bracket.
[0007] Furthermore, the longitudinal rear end of the inner bracket has a rearwardly downward sloping bent connection portion, which is pivotally connected to the front end of the drive linkage.
[0008] Furthermore, the top surface of the outer bracket is a support and fixing surface. The front and rear sides of the support and fixing surface are respectively provided with front fixing holes and rear fixing holes. The front feet and rear feet of the bottom of the refrigerator and washing machine pass through the corresponding front fixing holes and rear fixing holes from bottom to top and are connected and fixed to the bottom surface of the refrigerator and washing machine. The center of the front fixing hole and the center of the rear fixing hole are on the same longitudinal center line.
[0009] Furthermore, at least one of the front fixing hole and the rear fixing hole is an oblong hole that extends in a straight line along the longitudinal direction.
[0010] Furthermore, gaskets are provided between the top of the front fixing hole and the rear fixing hole and the bottom surface of the refrigerator and washing machine, and between the bottom and the support surface of the foot. The gaskets are provided with through holes for the screw of the foot to pass through. The through holes are round holes or waist-shaped holes extending in a longitudinal straight line.
[0011] Furthermore, the drive link is an arc-shaped link, and the center of the front fixing hole, the center of the rear fixing hole, and the pivot point between the front end of the arc-shaped link and the inner bracket are on the same longitudinal center line. The rear fixing hole is always located on one side of the arc-shaped inner circle of the arc-shaped link.
[0012] Furthermore, the arc-shaped connecting rod is provided with an arc-shaped pivot limiting groove, and the pivot limiting groove, the first connecting end of the handle, and the outer periphery of the pivot shaft of the outer bracket are matched and limited.
[0013] Furthermore, the wheel assembly includes an axle and a wheel mounted on the axle, the wheel being connected to the wheel state switching structure via the axle; the wheel state switching structure includes a vertical guide groove formed on the outer bracket and an oblique guide groove formed on the inner bracket, the oblique guide groove being inclined upwards from front to back along the longitudinal direction, the axle of the wheel assembly passing through the vertical guide groove and the oblique guide groove, and a wheel being mounted at each end of the axle.
[0014] Furthermore, the inclined guide groove includes a horizontal groove section and an inclined groove section, the inclined groove section sloping upwards from front to back, and the rear end of the horizontal groove section being connected to the front end of the inclined groove section.
[0015] Furthermore, a pin for longitudinal sliding limit is provided between the outer bracket and the inner bracket, and a limiting groove extending in a straight longitudinal direction is provided on the inner bracket, and the pin is disposed in the limiting groove.
[0016] The beneficial effects of this utility model are as follows: its driving component also includes a driving link, and the pivotal connection between the handle and the inner bracket is realized through the driving link. Since the handle is also pivotally connected to the outer bracket, when an external force drives the handle to rotate around the pivotal connection between the first connecting end and the outer bracket, the second connecting end of the handle drives the inner bracket to move relative to the outer bracket through the driving link, thereby increasing the force arm of the external force and making its operation more labor-saving and convenient.

[0029] Example 1:
[0030] See Figures 1-3 This utility model discloses an adjustable movable bracket for refrigerators and washing machines, comprising an outer bracket 10, an inner bracket 20, a wheel assembly 30, and a drive component 40. The outer bracket 10 directly supports and fixes the refrigerator and washing machine, and its bottom forms a longitudinally extending track cavity 11. The inner bracket 20 is slidably disposed within the track cavity 11 of the outer bracket 10. The outer and inner brackets are provided with mutually cooperating wheel state switching structures. The wheel assembly 30 is movably mounted on the outer bracket 10 and the inner bracket 20 through the wheel state switching structures. The wheel assembly 30 has a first state in contact with the ground and a second state detached from the ground. The drive component 40 can... The inner bracket 20 and the outer bracket 10 slide relative to each other in a longitudinal straight line. During this process, the wheel state switching structure drives the wheel assembly 30 to switch between a first state and a second state. The driving component 40 includes a handle 41 and a driving link 42. The handle 41 has a first connecting end 41a and a second connecting end 41b. The first connecting end 41a and the second connecting end 41b are set at an angle. In this embodiment, the angle is 90 degrees. The front end of the driving link 42 is pivotally connected to the longitudinal rear end of the inner bracket 20, and the rear end is pivotally connected to the second connecting end 41b of the handle. The first connecting end 41a of the handle is pivotally connected to the longitudinal rear end of the outer bracket 10.
[0031] Further details can be found here. Figure 5 The longitudinal rear end of the inner bracket 20 has a rearwardly downward sloping bent connection 21, which is pivotally connected to the front end of the drive link 42; thereby reducing the connection height between the drive link 42 and the inner bracket 20, and allowing the use of small-sized wheels to meet the requirements.
[0032] Further details can be found here. Figure 4 The top surface of the outer bracket 10 is a support and fixing surface. The front and rear sides of the support and fixing surface are respectively provided with front fixing holes 12 and rear fixing holes 13. The front feet and rear feet of the bottom of the refrigerator and washing machine pass through the corresponding front fixing holes 12 and rear fixing holes 13 from bottom to top and are connected and fixed to the bottom surface of the refrigerator and washing machine. The center of the front fixing hole 12 and the center of the rear fixing hole 13 are on the same longitudinal center line, which can ensure the stability of the refrigerator and washing machine in bearing and fixing during the adjustment process.
[0033] Furthermore, at least one of the front fixing hole 12 and the rear fixing hole 13 is an oblong hole extending in a longitudinal straight line; the oblong hole design allows for the selection of a suitable locking connection position according to different models and sizes of refrigerators and washing machines, thereby improving their versatility. In this embodiment, the front fixing hole 12 is a circular hole, and the rear fixing hole 13 is an oblong hole extending in a longitudinal straight line.
[0034] Furthermore, gaskets 14 are provided between the top of the front fixing hole 12 and the bottom surface of the refrigerator / washing machine, and between the bottom and the supporting surface of the feet. These gaskets can be moved to adjust the locking and connection positions of refrigerators / washing machines of different sizes and models. They also help to level uneven bottom surfaces and prevent deformation and twisting of the front and rear waist-shaped hole areas after prolonged use. The gaskets 14 have through holes for the screws of the feet to pass through; these through holes are either round or waist-shaped holes extending longitudinally.
[0035] In this embodiment, the drive link 42 is an arc-shaped link. The center of the front fixing hole 12, the center of the rear fixing hole 13, and the pivot point between the front end of the arc-shaped link and the inner bracket are on the same longitudinal center line. The rear fixing hole 13 is always located inside the arc-shaped inner circle of the arc-shaped link. This arrangement can avoid interference between the drive link 42 and the rear fixing hole 13. In actual use, installation and adjustment can be achieved without replacing the original feet of the refrigerator and washing machine.
[0036] The wheel assembly 30 includes an axle 31 and wheels 32 mounted on the axle. The wheels 32 are connected to a wheel state switching structure via the axle 31. The wheel state switching structure includes a vertical guide groove 15 formed in the outer bracket 10 and an inclined guide groove 22 formed in the inner bracket 20. The inclined guide groove 22 slopes upward from front to back longitudinally. The axle 31 of the wheel assembly passes through the vertical guide groove 15 and the inclined guide groove 22, and a wheel 32 is mounted at each end of the axle 31. With this configuration, when the inner bracket 20 can slide out relative to the outer bracket 10, the wheels 32 can move from the higher end of the inclined guide groove 22 to the lower end relative to the inner bracket 20. At the same time, the wheels 32 move from the upper end of the vertical guide groove 15 to the lower end relative to the outer bracket 10, so as to realize the transformation of the wheels 32 from the second state of being off the ground to the first state of being in contact with the ground, thereby facilitating the dragging and moving of refrigerator and washing appliances fixed on the outer bracket. A further technical solution is that the inclined guide groove 22 includes a horizontal groove section 22a and an inclined groove section 22b. The inclined groove section 22b slopes upward from front to back, and the rear end of the horizontal groove section 22a is connected to the front rear end of the inclined groove section.
[0037] A pin 16 for longitudinal sliding limit is provided between the outer bracket 10 and the inner bracket 20. A limiting groove 23 extending in a straight longitudinal direction is provided on the inner bracket 20, and the pin 16 is set in the limiting groove 23. In this way, when the inner bracket 20 slides relative to the outer bracket 10, the pin 16 and the limiting groove 23 can play an effective guiding and limiting role.
[0038] In practical application, this invention must be used in pairs. The two adjustable movable brackets of this invention are placed on either side of the bottom of the refrigerator / washing appliance. When the refrigerator / washing appliance is not moving (at this time, the inner bracket 20 is completely retracted into the track cavity 11 of the outer bracket 10), the wheels 32 on both brackets are in a second state of being out of contact with the ground (i.e., the wheels 32 are located at the highest end of the vertical guide groove 15 of the outer bracket 10 and the highest end of the inclined guide groove 22 of the inner bracket 20). At this time, the outer bracket 10 and the inner bracket 20 are directly in contact with the ground, while the wheels 32 are retracted to the side of the outer bracket 10 and not in contact with the ground. When the refrigerator / washing appliance is fixed on the two brackets and... When movement is required, an external force is applied to the handle 41, causing its first connecting end 41a to rotate around the outer bracket 10. This causes the second connecting end 41b of the handle 41 to drive the arc-shaped connecting rod 42 to move. The arc-shaped connecting rod 42 then drives the inner bracket 20 to slide out of the track cavity 11 of the outer bracket 10. During the extraction process, the axle 31 moves down along the inclined guide groove 22 from the highest end to the lowest end. At the same time, it moves down under the guidance of the vertical guide groove 15 of the outer bracket 10. As a result, the wheel 32 extends downward and gradually contacts the ground to reach the first state. The outer bracket 10 and the inner bracket 20 are then raised off the ground. Pushing or pulling the handle will make the wheel 32 roll, thus enabling the dragging and moving of the refrigerator and washing machine.
[0039] Example 2:
[0040] The difference between this embodiment and Embodiment 1 is that, see Figure 6 and Figure 7 The drive component 40 has an arc-shaped pivoting groove 42a on its arc-shaped connecting rod 42. The pivoting groove 42a, the first connecting end 41a of the handle 41, and the outer circumference of the pivot shaft of the outer bracket are engaged and limited. With this configuration, during the process of pushing and pulling the inner bracket 20, the pivoting groove 42a always contacts the first connecting end 41a of the handle 41 and the outer circumference of the pivot shaft of the outer bracket, and rotates around the pivot shaft. Thus, the pivot shaft also plays a radial support and limiting role on the rotation of the arc-shaped connecting rod 42, making the rotation and translation of the arc-shaped connecting rod 42 in the plane more stable and reliable. This improves the stability of the relative linear sliding between the inner bracket 20 and the outer bracket 10 (i.e., during the pulling process), avoids collision damage between the inner bracket 20 and the outer bracket 10 during the pulling process, and avoids the impact on the wheel axle 31, thereby improving the service life of the entire bracket.
[0041] The specific implementation of this utility model has been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
