Detailed Description

Fig. 1 is a schematic view of a mounting foot 10 according to an embodiment of the invention. The mounting feet 10 of the present embodiment are adapted to be mounted to the bottom of the device for mounting the device in a set position. The mounting foot 10 of the present embodiment can be applied to various devices, such as a refrigerator 70, an air conditioner, a washing machine, and other household appliances, and can also be applied to any other devices, particularly to an embedded refrigerator 70.

The mounting foot 10 may generally include a roller, a bracket and an adjustment portion 400, and may further include a connector. Wherein, the gyro wheel is installed on the bracket. The adjusting part 400 is mounted on the bracket through a connecting member.

The bracket includes a pallet 210, an upper turnover preventing part 220, and a lower turnover connecting shaft part 230.

A portion of the bracket forms a pallet 210, and the pallet 210 may be a horizontal plank wall portion on the bracket. Wherein "horizontal" is relative to the actual state of use of the mounting foot 10. In some alternative embodiments, the walls of the pallet 210 may also be curved.

The pallet 210 may be generally rectangular, circular, triangular, or any other polygonal shape. In this embodiment, the pallet 210 is substantially rectangular. The pallet 210 is provided with a light hole 211 penetrating the thickness direction of the main body plate surface of the pallet 210.

An upper flip stop 220 extends upwardly from the pallet 210 for insertion into a corresponding slot of a device mounted on the mounting foot 10 to limit rotation of the pallet 210 relative to the device. Preferably, the upper-flipping rotation-preventing part 220 extends upward from a portion of the tray table 210 spaced apart from an adjustment dial 420 (to be described in detail later) of the adjustment part 400, which may prevent the upper-flipping rotation-preventing part 220 from obstructing the rotation of the adjustment dial 420.

The flip-down shaft 230 extends downward from the pallet 210 and has a shaft hole 231 for engaging with a wheel axle 310 (described in detail below) of the wheel so that the wheel axle 310 of the wheel is rotatably connected to the bracket. In this embodiment, the downward-turning shaft part 230 may be a vertical side wall part on the bracket. The two downward hinge portions 230 may be formed to extend downward from opposite edge portions of the pallet 210. Each of the downturned shaft portions 230 has a shaft hole 231. The shaft holes 231 of the two downward-turning shaft parts 230 are oppositely arranged. Each shaft hole 231 is engaged with one end of the axle 310 of the roller.

In alternative embodiments, the position and number of the flip-down shaft portions 230 may be varied. The hinge shaft 230 may be one and extend downward from a middle portion of the pallet 210. The shaft hole 231 of the flip-down shaft 230 may be engaged with the middle section of the axle 310 of the roller.

The roller is rollably disposed under the pallet 210. The roller includes a wheel shaft 310 extending in a horizontal direction and a wheel body 320 rotating around the wheel shaft 310.

The adjustment part 400 is located above the light hole 211. The adjusting portion 400 has a screw 410 and an adjusting dial 420. The screw 410 is rotatably disposed on the pallet 210. The adjusting dial 420 is fixedly connected to the screw 410 or is integrated with the screw 410 to drive the screw 410 to rotate.

In the use state, the mounting foot 10 is provided with a screw 410 which is in threaded connection with a threaded hole at the bottom of the device, and a roller is supported on a supporting surface of the mounting space of the device, such as the ground. During the installation process of the device, since the roller can roll along the supporting surface where the mounting foot 10 is located, the screw 410 can rotate relative to the saddle 210, so that the mounting foot 10 of the present embodiment is suitable for both the leveling process and the moving process of the device. By adopting the mounting bottom foot 10 of the embodiment, the mounting difficulty of the device can be reduced, the mounting efficiency is improved, and the labor cost is saved.

For example, during installation of the device, a moving step may be performed first, followed by a leveling step. In the moving process, the roller rolls along the supporting surface, so that the friction resistance in the moving process can be reduced, and the moving difficulty is reduced. In the leveling step, the adjusting dial 420 is used for driving the screw 410 to rotate, and the screwing depth of the screw 410 screwed into the threaded hole at the bottom of the device can be adjusted, so that the height and/or the parallelism of the bottom of the device can be adjusted, and the operation is simple and convenient.

Because the screw 410 can rotate relative to the saddle 210, when the driving adjusting rotary disc 420 drives the screw 410 to rotate, the saddle 210 can be fixed, thereby preventing the roller from rotating along with the rotation of the screw 410, not only ensuring the leveling process of the device to be simple and convenient to operate, saving time and labor, but also reducing or avoiding the abrasion of the roller and prolonging the service life of the mounting foot 10.

The rotational axes of the dial 420 and the screw 410 are coaxial with the central axis of the dial 420 and the central axis of the screw 410. An adjustment dial 420 extends radially outward from a bottom section of the screw 410. In this embodiment, the rotation axis direction of the adjustment dial 420 and the screw 410 may be a vertical direction. The screw 410 may be formed to extend upward from a middle portion of the adjustment dial 420.

The dial 420 may be disc-shaped and the outer periphery of the dial 420 is formed with at least one recess 421 or protrusion to engage with a wrench tool and/or a drive belt (e.g., timing chain, timing belt). The adjustment dial 420 may have a set thickness to facilitate the application of force to the adjustment dial 420 by a wrench tool and/or a conveyor belt. The set thickness can be designed according to the practical application condition, for example, the set thickness can be 0.5-10 cm, and can also be any value larger than 10 cm. In alternative embodiments, adjustment dial 420 may also be square, hexagonal, or any other shape.

Generally, when the installation space of the device is narrow, the installer cannot reach a part of the device, which restricts the installer to adjust the device at the part, and the leveling process is difficult.

The adjustment dial 420 of this embodiment can be fitted with a drive belt and an active member, such as a gear or a cylinder with a groove on its outer periphery, can be provided at a location that is easily handled by the installer. The mounting feet 10, the drive belt, and the active member may form a mounting system. The transmission belt is wound on the driving part and the adjusting rotary disc 420, and the adjusting rotary disc 420 can be driven to rotate by rotating the driving part, so that the leveling difficulty of the device can be greatly reduced.

For example, when the refrigerator 70 is inserted into a cabinet, the adjusting dial 420 and, therefore, the screw 410 may be indirectly rotated by a belt. Due to the limited interior space of the cabinet, the leveling difficulty of the refrigerator 70 when it is inserted into the cabinet can be reduced by using the above-described mounting system.

Fig. 2 is a cross-sectional view of the mounting foot 10 shown in fig. 1, and fig. 3 is an exploded view of the mounting foot 10 shown in fig. 1.

One end of the connecting member is fixedly connected to the adjusting portion 400 or is an integral member with the adjusting portion 400, and the other end passes through the light hole 211 and is engaged with the lower peripheral edge of the light hole 211 to limit the degree of freedom of linear movement of the adjusting portion 400 relative to the pallet 210 in the direction of the rotational axis thereof. That is, when the adjustment part 400 is rotated along its rotation axis during installation of the apparatus, the connection member prevents the adjustment part 400 from moving in a vertical direction with respect to the pallet 210, so that the adjustment part 400 is not displaced in the vertical direction with respect to the pallet 210.

The connecting member is not fixedly connected to the lower periphery of the aperture 211, and only the adjusting portion 400 itself can rotate without driving the pallet 210 to rotate together, thereby reducing the rotation resistance and improving the installation efficiency.

In this embodiment, a bottom hole 401 is formed in the center of the bottom of the adjusting portion 400. And the connection includes a screw and washer 620. The screw has a main body portion 611 screwed into the bottom hole 401, and a head portion 612 located below the main body portion 611 and engaged with the periphery of the hole wall of the unthreaded hole 211. The screw may be a self-tapping screw. In alternative embodiments, the bottom hole 401 may be replaced with a threaded hole. And a washer 620 disposed between the head 612 and the adjustment part 400.

Fig. 4 is an enlarged partial view of mounting foot 10 shown in fig. 2 at a.

The wall of the aperture 211 is formed with an upper annular flange 201 on the upper surface of the pallet 210. The lower surface of the regulating portion 400 is formed with an annular groove 402 into which the upper annular flange 201 is inserted and rotatably fitted. Through setting up rotationally complex upper ring flange 201 and annular groove 402, can improve the stationarity and the centering nature of regulating part 400 rotation in-process for regulating part 400 is difficult for skewing at the rotation in-process, has improved the reliability of the use of erection footing 10. An upper annular flange 201 may be formed on the lower surface of the adjustment dial 420.

The lower surface of the dial 420 may also be formed with an annular concave surface located at the periphery of the annular groove 402. The depth of the annular concavity is less than the depth of the annular groove 402. The annular concave surface and the annular groove 402 have an annular bearing surface therebetween. The annular support surface is pressed against the upper surface of the pallet 210. There is a gap between the annular concave surface and the upper surface of the pallet 210, which is advantageous in reducing frictional resistance during rotation of the adjustment part 400.

A filler may be disposed between the annular concave surface and the upper surface of the pallet 210. The dynamic friction coefficient of the filler on the surface connected with the annular concave surface is small, and the dynamic friction coefficient of the filler on the surface connected with the upper surface of the saddle 210 is large. The filler can improve the stability of the rotation process of the adjustment part 400 and reduce the friction force of the rotation process by contacting with the annular concave surface of the adjustment dial 420.

Fig. 5 is a cross-sectional view of a mounting foot 10 according to another embodiment of the invention, and fig. 6 is a bottom view of a partial region of the bottom of the mounting foot 10 shown in fig. 5.

In alternative embodiments, the coupling member may be converted to a pawl 500. The connecting piece is a hollow cylindrical claw 500 with a plurality of convex buckles 510 at the periphery of the lower edge. The connector may extend downward from the bottom wall of the adjustment dial 420 through the light hole 211 to mate with the lower peripheral edge of the light hole 211.

Each male snap 510 has a clearance opening between the peripheral wall sections of the jaws 500 where it is located, i.e., the male snaps 510 are arranged in sequence with clearance along the circumference of the lower edge of the jaws 500. When the lower edge of the latch 500 is inserted into the aperture 211, the outer circumference of the lower edge of the latch 500 is inwardly contracted by a radially inward force, thereby smoothly passing through the aperture 211.

The lower surface of each male snap 510 is a slope inclined upward in a radially outward direction, which facilitates the smooth passing of the lower edge of the latch 500 through the light hole 211. Here, "outward" is with respect to the actual usage state of the hollow cylindrical pawl 500.

The central axis of the hollow cylindrical jaw 500 extends in the vertical direction. The upper surface of each male snap 510 is a plane perpendicular to the peripheral wall of the pawl 500, which may be a substantially horizontal plane. The upper surface of each male snap 510 may form a snap fit with the aperture wall of the optical aperture 211. The wall of the aperture 211 is formed with a lower annular flange 202 on the lower surface of the tray 210 to form a snap fit with the upper surface of the male snap 510, which is advantageous for preventing the upper surface of the male snap 510 from contacting the body deck of the tray 210.

And the adjusting part 400 is pressed against the upper surface of the pallet 210 through an annular gasket or an annular protrusion 422 formed on the lower surface of the adjusting part 400, which can reduce the contact area between the adjusting part 400 and the upper surface of the pallet 210, and is beneficial to reducing the frictional resistance when the adjusting part 400 rotates. An annular gasket may be disposed between the lower surface of the adjustment dial 420 and the upper surface of the pallet 210. An annular protrusion 422 may be formed on the lower surface of the dial 420.

Fig. 7 is a cross-sectional view of a mounting foot 10 according to yet another embodiment of the invention.

In this embodiment, the adjusting portion 400 may not be provided with the annular washer and the annular protrusion 422, and the lower surface of the adjusting portion 400 may be planar and directly abut against the upper surface of the saddle 210, which is beneficial to improving the mechanical strength of the mounting foot 10.

Fig. 8 is a schematic view of a mounting foot 10 according to yet another embodiment of the invention. In this embodiment, the adjustment dial 420 has a disc shape. The number of the adjusting portions 400 is two, and the two adjusting portions are a first adjusting portion and a second adjusting portion. A plurality of first gear teeth are formed on the outer periphery of the adjusting dial 420 of the first adjusting portion, and a plurality of second gear teeth are formed on the outer periphery of the adjusting dial 420 of the second adjusting portion, and the second gear teeth are in transmission engagement with the first gear teeth. And the disc diameter of the regulating disc 420 of the first regulating part is larger than that of the regulating disc 420 of the second regulating part. The screw 410 of the first adjustment part has a screw thread opposite to the screw 410 of the second adjustment part, for example, the screw 410 of the first adjustment part may have an orthodontic screw thread and the screw 410 of the second adjustment part may have a counter-thread screw thread. The first gear teeth and the second gear teeth may each be engaged with a wrench tool and/or a drive belt.

The second gear teeth are in driving engagement with the first gear teeth such that the adjustment dial 420 of the second adjustment portion is drivenly rotatable with the adjustment dial 420 of the first adjustment portion. The disc diameter of the dial 420 of the first adjustment part is larger than the disc diameter of the dial 420 of the second adjustment part. Wherein, the disc diameter refers to the diameter of the circle on which the outer circumference of the disc is located. The disc diameter of the adjusting disc 420 of the first adjusting portion is larger than that of the adjusting disc 420 of the second adjusting portion, which is convenient for arranging a transmission belt on the mounting foot 10, and the transmission belt can be sleeved on the adjusting disc 420 of the first adjusting portion, so as to directly drive the adjusting disc 420 of the first adjusting portion to rotate. The adjusting dial 420 of the second adjusting portion may be passively disposed at one side of the adjusting dial 420 of the first adjusting portion and at an inner side of the transmission belt, so as to rotate along with the adjusting dial 420 of the first adjusting portion.

The installation footing 10 of this embodiment, in the installation of device, can also utilize spanner tool and/or drive belt to adjust the regulation capstan 420 of first regulating part to make the regulation capstan 420 of first regulating part drive the regulation capstan 420 of second regulating part and rotate, thereby adjust the screw rod 410 of first regulating part and the screw rod 410 screw in of second regulating part simultaneously and correspond the degree of depth of screw hole, this both can guarantee the regulation stationarity of device, can simplify the accommodation process of installation footing 10 again.
