Detailed Description
Fig. 1 is a schematic view of a mounting foot 10 according to one 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 base 200, a movable bracket, a roller 400, and an adjustment portion, and may further include a first connector, a bushing 800, and a second connector. Wherein, the roller 400 is installed at the bottom of the base 200. The movable support can be covered on the base 200. The adjusting part is connected with the base 200 and the movable bracket at the same time. The shaft sleeve 800 is disposed on the base 200 and connected to the movable bracket through a second connecting member.
The movable frame is movably disposed on the base 200 and includes a supporting plate 310, a horizontal lug portion 320 and a downward-turned sidewall portion 330. At least a portion of the movable support forms a pallet 310, and the pallet 310 is positioned above the base 200. The support plate 310 may be a horizontal plate wall on a mobile rack. The support plate 310 is adapted to be coupled to the bottom of the device to which the mounting feet 10 are mounted to hold the bottom of the device against.
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.
The roller 400 includes a wheel shaft 410 extending in a horizontal direction and a wheel body 420 rotating about the wheel shaft 410.
The base 200 may be cylindrical, for example, a cylinder (the upper and lower surfaces of the cylinder are circular), a square column (the upper and lower surfaces of the square column are rectangular), or any other shape of column. For example, the base 200 may have a substantially rectangular parallelepiped shape. Both the upper surface (i.e., the top wall of the base 200) and the lower surface (i.e., the bottom wall of the base 200) of the base 200 may extend in the horizontal direction, and the side surfaces (i.e., the side walls of the base 200) of the base 200 may extend in the substantially vertical direction.
Fig. 4 is a schematic view of base 200 of mounting foot 10 shown in fig. 1, and fig. 5 is another schematic view of base 200 of mounting foot 10 shown in fig. 1.
The base 200 has a first end section 210, a second end section 220, and a middle section 230. The first end section 210, the middle section 230, and the second end section 220 may be arranged in sequence along the front-to-rear extension direction of the chassis 200. The dashed lines in fig. 5 generally show the dividing lines between the middle section 230 and the first end section 210 and the second end section 220. The "front-rear extending direction" is substantially horizontal with respect to the actual use state of the mounting foot 10. That is, the first end section 210 may be located at the front side of the base 200, the second end section 220 may be located at the rear side of the base 200, and the middle section 230 may be located between the first end section 210 and the second end section 220. In this embodiment, the base 200 has a length extending direction and a width extending direction. The front-rear extending direction may be substantially the longitudinal extending direction of the base 200.
Wherein at least a portion of the first end section 210 is recessed downward to form a first recess 211 to define an adjustment space 212 with the plate 310 of the movable bracket. Wherein "downward" is relative to the actual use of the mounting foot 10 and may be generally vertically downward. That is, the upper surface of the first recess 211 is lower than the upper surfaces of the second end section 220 and the middle section 230, and since the support plate 310 of the movable bracket is located above the base 200, there is a space between the first recess 211 and the support plate 310 of the movable bracket to form the adjustment space 212. The adjustment space 212 may be used to mount an adjustment dial 520 of the adjustment portion.
The shape of the adjustment space 212 may be adapted to the shape of the adjustment dial 520 so that the adjustment dial 520 may rotate within the adjustment space 212 without interfering with the sidewalls of the adjustment space 212.
The base 200 is formed with a screw hole 213 to be engaged with a screw 510 of the adjusting portion. The screw hole 213 is disposed in the first recess 211. The screw hole 213 may penetrate the middle of the first recess 211 and extend in a vertical direction. The screw hole 213 is located below the adjustment space 212. When the adjustment portion screw 510 is fully threaded into the threaded bore 213, the upper surface of the adjustment dial 520 may remain flush with the upper surfaces of the middle and second end sections 230, 220, or slightly below the upper surfaces of the middle and second end sections 230, 220.
Fig. 6 is a schematic view of the adjustment portion of the mounting foot 10 shown in fig. 1.
The adjustment portion has a threaded rod 510 and an adjustment dial 520, and may also have a first circular flange 530 and a second circular flange 540. The screw 510 is rotatably screwed to the screw hole 213. The adjusting dial 520 is disposed in the adjusting space 212 and is fixedly connected to the screw 510 or is integrated with the screw 510 to drive the screw 510 to rotate.
In the use state, the mounting foot 10 has a screw 510 screwed to the base 200 and a roller 400 supported on a support surface of the installation space, for example, the ground. When the screw 510 rotates, the adjusting dial 520 can drive the movable support to lift, thereby realizing the lifting and leveling of the device. In the installation and leveling process of the device, since the roller 400 can roll along the supporting surface where the installation foot 10 is located, the screw 510 can indirectly drive the movable bracket to move, so that the installation foot 10 of the embodiment is suitable for both the leveling process and the moving process of the device. By adopting the mounting footing 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 400 rolls along the supporting surface, so that the friction resistance in the moving process can be reduced, and the moving difficulty can be reduced. In the leveling step, the adjusting dial 520 is used to drive the screw 510 to rotate, so that the screwing depth of the screw 510 screwed into the threaded hole 213 of the base 200 can be adjusted, the height and/or the parallelism of the bottom of the device can be adjusted, and the operation is simple and convenient.
The rotational axes of dial 520 and screw 510 are coaxial with the central axis of dial 520 and the central axis of screw 510. An adjustment dial 520 extends radially outward from the top section of the screw 510. In this embodiment, the rotation axis directions of the adjustment dial 520 and the screw 510 may be vertical directions. The screw 510 may be formed to extend downward from a middle portion of the adjustment dial 520.
The dial 520 may be disc-shaped and the outer circumference of the dial 520 may be formed with at least one groove 521 or protrusion to engage with a wrench tool and/or a driving belt (e.g., a timing chain, a timing belt). The adjustment dial 520 may have a set thickness to facilitate the application of force to the adjustment dial 520 by a wrench tool and/or a conveyor belt. The set thickness may be designed according to the actual application, and may be, for example, 0.5 to 10cm or an arbitrary value larger than 10 cm. In alternative embodiments, the adjustment dial 520 may 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 520 of this embodiment can be engaged with a drive belt and can be provided with a driving member, such as a gear or a cylinder having a groove on its outer periphery, at a position where it is easy for an installer to operate. 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 520, and the adjusting rotary disc 520 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 adjustment dial 520 may be rotated by a belt, thereby indirectly rotating the screw 510. 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.
The upper surface of the adjustment dial 520 is formed with a first circular flange 530 and a second circular flange 540. The central axis of the first circular flange 530 and the central axis of the second circular flange 540 are coaxial with the central axis of the adjustment dial 520. The first circular flange 530 is higher than the second circular flange 540. First circular flange 530 and second circular flange 540 may be one-piece with adjustment dial 520. The first and second circular flanges 530 and 540 may be substantially cylindrical.
The supporting plate 310 has a first aperture 311 above the adjustment space 212, and the first aperture penetrates the supporting plate 310 in the thickness direction of the main body plate surface. Here, the "thickness direction" may be a substantially vertical direction. The central axis of the first unthreaded hole 311 may be coaxial with the central axis of the threaded hole 213. And the first light hole 311 is for the first circular flange 530 to extend into and rotatably fit. The diameter of the first circular flange 530 is slightly smaller than or equal to the inner diameter of the first light hole 311. The top end of the first circular flange 530 protrudes from the first light hole 311.
Through setting up first circular flange 530 and first unthreaded hole 311 of rotationally cooperating, can improve the stationarity and the centering nature of regulating part rotation in-process for the regulating part is difficult for skewly at the rotation in-process, has improved the reliability of the use of installation footing 10.
The second circular flange 540 is located below the lower periphery of the first aperture 311. The diameter of the second circular flange 540 is larger than the inner diameter of the first unthreaded hole 311. The second circular flange 540 abuts the support plate 310 at the lower periphery of the first aperture 311. And the area of the upper surface of the second circular flange 540 is smaller than the entire area of the upper surface of the adjustment dial 520, so that a gap exists between the portion of the upper surface of the adjustment dial 520 located outside the second circular flange 540 and the support plate 310. The second circular flange 540 is only used to directly contact the supporting plate 310, which is advantageous in reducing the contact area between the adjustment part and the supporting plate 310, thereby reducing the frictional resistance during the rotation of the adjustment part.
The center of the top section of the adjusting part is provided with a first connecting hole 501. The first connection hole 501 may penetrate through the first circular flange 530, the second circular flange 540, the adjustment dial 520, and extend downward into the screw 510.
The first connector has a first screw 610 and a first washer 620. The first screw 610 has a first body portion screwed into the first connection hole 501, and a first head portion located above the first body portion and clamped to the upper surface of the first circular flange 530. The first washer 620 is disposed between the first head and the first circular flange 530. The first gasket 620 may have a substantially circular shape with a diameter greater than an inner diameter of the first light hole 311. The first screw 610 may be a self-tapping screw. In alternative embodiments, the first connection hole 501 may be replaced with a threaded hole.
The first connecting member is not fixedly connected to the upper periphery of the first aperture 311, and only the adjusting portion itself can rotate without driving the movable bracket to rotate together, so that the rotational resistance can be reduced, and the installation efficiency can be improved.
The second end section 220 of the base 200 is opposite the first end section 210. The mounting foot 10 is formed with a second light hole 312 that extends through the second end section 220 and the thickness of the plate 310. Here, the "thickness direction" may be a substantially vertical direction. The second light aperture 312 is substantially cylindrical. The central axis of the second light hole 312 extends in the vertical direction.
The sleeve 800 is slidably disposed within the second optical aperture 312. The sleeve 800 may also be cylindrical, and the height of the sleeve 800 is the same as the height of the second light hole 312. A gap is formed between a sidewall of the shaft sleeve 800 and a wall of the second aperture 312, so that the shaft sleeve 800 is slidably disposed in the second aperture 312. The sleeve 800 inserted into the second light hole 312 may play a certain supporting role.
The center of the top section of the bushing 800 is opened with a second connection hole 801. One end of the second connecting member is engaged with the supporting plate 310, and the other end is fixedly connected with the shaft sleeve 800, so that the supporting plate 310 is connected with the shaft sleeve 800. The second connector includes a second screw 910 and a second washer 920. The second screw 910 has a second main body portion screwed into the second connection hole 801, and a second head portion located above the second main body portion. The second washer 920 is disposed between the second head and the support plate 310. In this embodiment, the upper surface of the second washer 920 abuts against the second head, and the lower surface of the second washer 920 abuts against the upper surface of the shaft sleeve 800 and the supporting plate 310 at the same time.
The middle section 230 of the base 200 is connected between the first end section 210 and the second end section 220. The upper surface of the first end section 210 and the upper surface of the middle section 230 are in the same horizontal plane.
At least a portion of the bottom wall of the middle section 230 is recessed upwardly to form a second recess 231 to define a rotation cavity 232 for receiving the roller 400. Here, "upward" is relative to the actual usage state of the mounting foot 10, and may be a substantially vertical upward direction. The shape of the rolling cavity 232 may be adapted to the shape of the roller 400, so that the roller 400 may rotate flexibly in the rolling cavity.
The first end section 210, the middle section 230, and the second end section 220 are sequentially arranged in a horizontal direction. In this embodiment, the first end section 210, the middle section 230 and the second end section 220 are arranged in sequence along the length direction of the base 200. The axle 410 extends perpendicular to the alignment of the first end section 210, the middle section 230, and the second end section 220. That is, the axle 410 extends in the width direction of the base 200. A shaft hole 233 is formed on a side wall of the rotation chamber 232 to be engaged with the wheel shaft 410 so that the wheel shaft 410 is rotatably coupled to the base 200. The side wall of the rotation chamber 232 may refer to two side walls of the rotation chamber 232 that are oppositely disposed in the width direction of the base 200.
The mounting feet 10 are such that, in use, the device is pressed against the mounting feet 10. When the adjusting dial 520 drives the screw 510 to rotate, the bottom end of the wheel body 420 is pressed against the supporting surface of the device, the shaft sleeve 800 forms an adjusting fulcrum, and the device moves up and down around the adjusting fulcrum.
The horizontal lug part 320 of the movable bracket is formed to protrude outward from the support plate 310 in a horizontal direction. The horizontal lug portion 320 is provided with a bolt hole 321 so that the movable bracket is fixed to the bottom of the device to which the mounting foot 10 is mounted by means of a nut. Since the support plate 310 is a horizontal plate wall portion of the movable bracket, the horizontal lug portion 320 may be formed to protrude horizontally outward from any edge portion of the support plate 310. In this embodiment, there may be two horizontal lug parts 320.
Because the screw 510 can rotate in the threaded hole 213, the movable bracket can be fixedly connected with the bottom of the device through the horizontal lug part 320, when the driving adjusting rotary disc 520 drives the screw 510 to rotate, the rotation of the base 200 can be reduced or avoided, and the roller 400 can be prevented from rotating along with the rotation of the screw 510, so that the leveling process of the device is simple and convenient to operate, time and labor are saved, the abrasion of the roller 400 can be reduced or avoided, and the service life of the mounting bottom foot 10 is prolonged.
The flip-down sidewall portion 330 of the mobile bracket extends downward from the support plate 310 and is disposed corresponding to the sidewall of the base 200 to define the mobile direction of the mobile bracket.
