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.
Fig. 2 is a cross-sectional view of the mounting foot 10 shown in fig. 1.
The mounting foot 10 may generally include a post 200, a ball 300, and a screw 410, and may further include a screw head 420. Wherein the ball 300 is mounted on the post 200. The screw 410 is fixedly connected to the post 200 or is integrated with the post 200.
The post 200 may be cylindrical, square (with top and bottom walls each rectangular), or any other form of post. In this embodiment, the post 200 may be cylindrical. The post 200 has a bottom wall, a top wall and a cylindrical body connected between the bottom wall and the top wall. The bottom wall and the top wall of the support column 200 are both circular and are both located on the horizontal plane. The center of the bottom wall, the center of the top wall and the central axis of the column of the support column 200 are collinear and all located on the same vertical line.
A portion of the bottom wall of the post 200 is recessed to form a plurality of ball pockets 210. Here, "inward" is relative to the actual usage state of the post, and may be generally upward. The ball portion 210 defines a moving space of the ball 300. The ball 300 is spherical and is plural, and each ball 300 is rollably fitted in one of the ball portions 210.
The number of the ball portions 210 is not less than 3, and may be 3 or 4, for example. The plurality of ball socket portions 210 are uniformly distributed at intervals on the same circumference centered on the center of the bottom wall of the cradle 200.
In the situation of use, a device is carried above the mounting foot 10, the mounting foot 10 acting as a support device. The ball socket portions 210 are arranged to be evenly distributed at intervals on the same circumference with the center of the bottom wall of the support column 200 as the center of a circle, which is beneficial to improving the distribution uniformity of the balls 300, thereby improving the stability of the mounting foot 10 in the supporting device.
The ball portion 210 is a hollow cylindrical hole whose central axis extends in the vertical direction. For example, the ball portion 210 may be a hollow cylindrical bore. The depth of the ball portion 210 is referred to as the hole depth. From top to bottom, the socket portion 210 may have a socket top, side walls, and a socket bottom. Wherein the socket top is located at the top end of the socket portion 210, which may be circular. The socket bottom is located at the bottom end of the socket portion 210 and is formed with an opening so that the ball 300 can protrude from the opening and contact a supporting surface (e.g., the ground) on which the device is located when being inserted into the socket portion 210.
In the horizontal direction, there is a gap between the periphery of the sidewall of the socket portion 210 and the ball 300, that is, the diameter of the circle of the cross section of the sidewall of the socket portion 210 is greater than the diameter of the ball 300, which is beneficial to improving the flexibility of the ball 300 during the movement of the socket portion 210 and reducing or avoiding the ball 300 from being jammed.
In the vertical direction, the socket portion 210 is configured such that at least a portion of the ball 300 protrudes from the bottom end of the socket portion 210 when the ball 300 is embedded therein, i.e., the socket bottom of the socket portion 210, so that the ball 300 can be pressed against the supporting surface of the device during the installation of the device and roll along the supporting surface of the device.
The socket portion 210 is formed with a lower annular flange 211 below the bottom wall of the post 200. A lower annular flange 211 extends radially inward from a bottom section of the socket portion 210. That is, the lower annular flange 211 is formed on the bottom section of the socket portion 210 and is located below the bottom wall of the post 200. The lower annular flange 211 is annular.
The inner diameter of the lower annular flange 211 is smaller than the diameter of the ball 300, which prevents the ball 300 fitted in the socket portion 210 from being separated from the socket portion 210.
And the ratio between the diameter of the ball 300 and the inner diameter of the lower annular flange 211 is greater than a set threshold, so that the protruding proportion of the ball 300 protruding out of the bottom end of the ball socket portion 210 can be limited, and the purpose of proper amount of protrusion is achieved, which is not only beneficial to improving the support stability of the mounting foot 10, but also beneficial to improving the rolling flexibility of the mounting foot 10. The setting threshold can be set according to actual needs, and can be any value within the range of 1.1-1.8, for example.
The depth of the socket portion 210 is smaller than the diameter of the ball 300. When the device is carried over the mounting foot 10, the balls 300 can abut against the ball socket top of the ball socket portion 210 on the one hand and the ground on which the device is located on the other hand, which is advantageous for improving the structural strength of the mounting foot 10.
The ball 300 may be a universal ball, for example, a steel ball, and may rotate along 360 degrees horizontally, so that the device mounted with the mounting foot 10 may slide flexibly, the moving difficulty of the refrigerator 70 is reduced, and the rotating difficulty of the screw 410 of the mounting foot 10 is also reduced, thereby greatly reducing the labor intensity of the mounting process, and making the leveling process of the device easy and simple to operate, and saving time and labor.
The screw 410 is fixedly connected with the support column 200 or is an integral piece with the support column 200 and is rotatably screwed in a threaded hole at the bottom of the device provided with the mounting foot 10. The screw 410 has external threads that can be threaded into a threaded hole in the bottom of the device. When the screw 410 rotates, the depth of the screw 410 screwed into the threaded hole at the bottom of the device can be adjusted.
In the installation foot 10 in the use state, the screw 410 is screwed with the threaded hole at the bottom of the device, and the ball 300 is supported on the support surface of the installation space where the device is arranged, for example, the ground. During the installation of the device, since the balls 300 can roll along the support surface where the mounting foot 10 is located, the screw 410 can rotate relative to the threaded hole at the bottom of the device, 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 ball 300 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 screw 410 is driven 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 ball 300 protrudes out of the bottom end of the ball socket portion 210 of the support column 200 and is directly pressed against the supporting surface, the screw 410 can rotate synchronously with the support column 200, when the screw 410 is driven to rotate, the ball 300 can rotate horizontally by 360 degrees, the rotation difficulty of the screw 410 of the mounting foot 10 can be reduced, the labor intensity in the mounting process can be greatly reduced, the abrasion of the support column 200 due to the contact with the supporting surface can be reduced or avoided, and the service life of the mounting foot 10 is prolonged.
The rotation axes of the screw 410 and the post 200 are coaxial with the central axis of the screw 410 and the central axis of the post 200. And a screw 410 is formed to extend upward from the post 200. In this embodiment, the rotation axis directions of the screw 410 and the post 200 may be vertical directions. For example, the screw 410 may be formed to extend upward from a middle portion of the top section of the post 200.
In some alternative embodiments, the mounting feet may also include a threaded head 420. The screw head 420 and the screw 410 are one piece. The screw head 420 is embedded in the post 200, for example, may be embedded in the middle of the top section of the post 200. And the screw head 420 extends radially outward from the bottom section of the screw 410, the central axis of the screw head 420 being coaxial with the central axis of the screw 410.
The screw head 420 and the screw 410 may form a bolt. That is, the head 420 of the bolt may be directly embedded in the top section of the post 200, which may simplify the process of forming the mounting foot 10 and may improve the connection strength between the screw 410 and the post 200.
The outer periphery of the top section of the post 200 is formed with at least one groove 220 or protrusion to mate with a wrench tool and/or a drive belt (e.g., timing chain, timing belt). The recess 220 or protrusion may have a set height to facilitate the application of a force to the recess 220 or protrusion by a wrench tool and/or a conveyor belt. The set height can be designed according to the practical application condition, for example, the set height can be 0.5-10 cm, and can also be any value larger than 10 cm. The outer circumference of the top section of the post 200 may form an annular spline to engage with the teeth of the timing belt. The outer periphery of the top section of the post 200 may form an annular toothed disc to mate with the tooth slots of the timing chain.
The groove 220 or the protrusion is directly formed on the top section of the support pillar 200, and the groove 220 or the protrusion is used as an adjusting part for rotating the adjusting screw 410, so that the structural integrity of the mounting foot 10 can be improved, the structure of the mounting foot 10 is simplified, and the manufacturing cost is saved.
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 post 200 of this embodiment is capable of engaging a belt and may be provided with an active member, such as a gear or a cylinder having a groove 220 on its outer periphery, at a location that is easily accessible to an 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 top section of the support column 200, the support column 200 can be driven to rotate by rotating the driving part, and then the screw 410 can be driven to rotate, so that the leveling difficulty of the device can be greatly reduced.
For example, the refrigerator 70 may be equipped with the above-described mounting system. When the refrigerator 70 is inserted into the cabinet, the supporting post 200 may be rotated by a driving belt, thereby indirectly rotating the screw 410. 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.
In some further embodiments, the number of screws 410 may be varied. For example, the two screws 410 may be symmetrically disposed on the post 200. Each screw 410 is adapted to be rotatably threaded into a threaded bottom hole of the device to which the mounting foot 10 is mounted. The two screws 410 have the same thread direction. When the driving support post 200 rotates, the two screws 410 can be driven to rotate at the same time, so that the depths of the two screws 410 screwed into the corresponding threaded holes can be adjusted at the same time, which is beneficial to improving the adjustment stability of the device.
Fig. 3 is a schematic diagram of a refrigerator 70 according to one embodiment of the present invention. The bottom of the refrigerator 70 is provided with at least one mounting foot 10 of any of the embodiments described above. And the bottom of the refrigerator 70 is provided with a threaded hole, and the screw 410 of the mounting foot 10 is in threaded connection with the threaded hole.
Since the mounting foot 10 of the refrigerator 70 of the present embodiment has both the leveling function and the moving function, it is possible to reduce or avoid mounting other auxiliary structures on the bottom of the refrigerator 70, thereby simplifying the mounting structure of the refrigerator 70 and reducing the manufacturing cost.
The number of mounting feet 10 can be four, two of which can be disposed on the bottom front side of the refrigerator 70 and the other two of which can be disposed on the bottom rear side of the refrigerator 70.
In other alternative embodiments, there may be two mounting feet 10, each disposed on the bottom rear side of the refrigerator 70. The bottom front side of the refrigerator 70 may be provided with a front wheel that can be rolled.
Fig. 4 is a schematic view of a bottom plate 710 and mounting feet 10 of a refrigerator 70 according to one embodiment of the present invention. Fig. 5 is another schematic view of the bottom plate 710 and mounting feet 10 of the refrigerator 70 according to one embodiment of the present invention, showing a specific mounting scenario. The key tool is shown for rotating the post 200 to rotate the screw 410.
The screw hole is formed on the bottom plate 710 of the refrigerator 70. The bottom plate 710 may be a bottom plate 710 of the cabinet of the refrigerator 70, or a bottom plate 710 additionally provided on the cabinet. A screw cylinder extending upward from a plate surface where the bottom plate 710 is located is formed on the bottom plate 710 of the refrigerator 70, and a screw hole is formed inside the screw cylinder.
The mounting foot 10 and the refrigerator 70 with the same of the present embodiment, wherein the mounting foot 10 comprises a support pillar 200, a plurality of balls 300 and a screw 410. Each ball 300 is rollably inserted into one of the ball sockets 210 of the post 200, and the screw 410 is fixedly connected to the post 200 or is an integral part of the post 200, and is adapted to be rotatably screwed into a bottom threaded hole of the device to which the mounting foot 10 is attached. In the installation process of the device, because the ball 300 can roll along the supporting surface where the installation footing 10 is located, the screw 410 can rotate relative to the threaded hole at the bottom of the device, so that the installation footing 10 of the embodiment is suitable for both the leveling process and the moving process of the device, and has the advantages of small volume, simplicity and easiness in adjustment, large adjustment range and low manufacturing cost. 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.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
