DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0048] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] like Figures 1 to 8 As shown, a portable adjustable and detachable mobile bracket of the present invention is used for washing machines as an example, and includes a bracket assembly 2, a rolling module 3 movably mounted on the bracket assembly 2, a lifting mechanism 223 movably mounted on the bracket assembly 2, and an adjustment mechanism connected to the lifting mechanism 223. The rolling module 3 has a first position and a second position relative to the bracket assembly 2. The distance that the rolling module 3 protrudes from the lower surface of the bracket assembly 2 in the second position is greater than the distance that the rolling module 3 protrudes from the lower surface of the bracket assembly 2 in the first position. That is to say, when the rolling module 3 is in the second position, the bracket assembly 2 is supported to rise. When the rolling module 3 is in the first position, the raised bracket assembly 2 is lowered to the height before the bracket assembly 2 is raised. The adjustment mechanism is used to provide a force to drive the lifting mechanism 223 to drive the rolling module 3 to move between the first position and the second position. On the one hand, the lifting and lowering of the bracket assembly 2 is realized, and on the other hand, it is convenient for the bracket assembly 2 to lift the washing machine box 1 supported by the foot 11 and move it to a specified position.

[0051] Further, the lifting mechanism 223 can be a screw. The adjustment mechanism includes a worm wheel 222 and a worm 221. One side of the inner ring of the worm wheel 222 extends outward along the inner ring wall. The inner ring of the worm wheel 222 is provided with an internal thread that matches the peripheral side of the screw, and preferably, the inner ring of the worm wheel 222 coincides with the axis of the peripheral side of the screw, and the outer ring of the worm wheel 222 is provided with an external thread that matches the worm 221. The worm 221 is used to provide a force to drive the worm wheel 222 to rotate, and further drive the screw matched with the inner ring of the worm wheel 222 to move along a preset path.

[0052] A bearing 227 is also fixedly mounted on the bracket assembly 2. The bearing 227 is sleeved on the portion of the worm wheel 222 extending outward along the inner ring wall. On the one hand, it supports the bracket assembly 2, and on the other hand, it prevents the worm wheel 222 of the adjustment mechanism from moving relative to the bracket assembly 2.

[0053] The rolling module 3 includes a rolling portion 31 and a base 32, wherein a portion of the rolling portion 31 is rollably mounted on one side of the base 32 moving in the direction of the second position, and another portion is in rolling contact with the ground, and the lifting mechanism 223 is disposed on the other side of the base 32 opposite to the rolling portion 31. The rolling portion 31 of the present invention may be a ball mounted on the base 32, or may be a roller.

[0054] On the lifting mechanism 223, a limit block 2231 is provided at the end away from the base 32. When the limit block 2231 is at the end of the lifting mechanism 223 away from the base 32, the lifting mechanism 223 is restricted from continuing to move toward the ground, thereby preventing the lifting mechanism 223 from disengaging from the adjustment mechanism when driving the rolling module 3 to move to the second position.

[0055] The support assembly 2 includes two main supports 224 and at least one connecting frame 225. The lifting mechanism 223 and the adjusting mechanism are both installed in the main supports 224. The rolling module 3 drives the support assembly 2 to move along the length direction of the main supports 224. The two ends of at least one connecting frame 225 are respectively connected to a main support 224, and the two main supports 224 are arranged side by side. The connecting frame 225 and the main support 224 can be independent structures, or they can be an integral structure formed by connecting the two ends of the connecting frame 225 to the main support 224. In order to facilitate the installation and disassembly of the support assembly 2, it is preferably an integral structure formed by connecting the connecting frame 225 and the main support 224. Three connecting frames 225 of the present invention are provided to improve the overall stability of the support assembly 2, and the space between the main supports 224 at both ends of the connecting frame 225 is divided into four parts.

[0056] The main support 224 includes an upper frame 21 and a lower frame 22, wherein the upper frame 21 is installed with the lower frame 22 by snapping or pulling. The present invention takes the installation of the upper frame 21 and the lower frame 22 by snapping as an example. A through hole is provided on one side of the lower frame 22, and a plurality of through holes are evenly arranged, and a preset gap is left between the through holes. The number of the bases 32 corresponds to the number of through holes. The lower frame 22 has an upwardly open mounting groove, and the adjustment mechanism is rotatably arranged in the mounting groove. One end of the worm 221 of the adjustment mechanism protrudes from the mounting groove, and the cross section of the portion of the worm 221 protruding from the mounting groove can be set to a polygon, that is, the portion of the worm 221 protruding from the mounting groove is a three-dimensional structure formed by extending along the length direction of the worm 221 with a polygonal cross section as the bottom surface, so that the user can hold the portion of the worm 221 protruding from the mounting groove and rotate the worm 221 to provide a force. Preferably, the worm 221 can be connected to a driving motor.

[0057] The lifting mechanism 223 is installed in cooperation with the adjusting mechanism, and one end of the lifting mechanism 223 connected to the rolling module 3 is arranged through the through hole of the lower frame 22. When the adjusting mechanism provides a force to drive the lifting mechanism 223 to move in a direction close to the ground, and the base 32 passes through the through hole, until the rolling portion 31 provided on the base 32 rolls in contact with the ground, the lifting mechanism 223 is reciprocated between the first position and the second position along the radial direction of the lifting mechanism 223 by the limitation of the through hole.

[0058] The lower frame 22 includes a first mounting portion 226, which is disposed on the same side of the lower frame 22 as the through hole, and a plurality of first mounting portions 226 are evenly arranged in a row. The first mounting portion 226 of the present invention may be a groove.

[0059] The upper frame 21 includes a connecting portion and a second mounting portion 212, wherein a plurality of second mounting portions 212 are evenly arranged in a row, arranged opposite to the first mounting portion 226, and located on a side close to the first mounting portion 226. The second mounting portion 212 is buckled with the first mounting portion 226 up and down to form a space that can accommodate the connecting portion. The connecting portion is arranged in the space formed by the mutual buckling of the first mounting portion 226 and the second mounting portion 212, and is used to connect the first mounting portion 226 and the second mounting portion 212, so as to realize a detachable connection between the first mounting portion 226 and the second mounting portion 212. The second mounting portion 212 of the present invention is a groove corresponding to the first mounting portion 226, and the connecting portion is a magnet block adapted to the groove.

[0060] A rubber pad is provided at the end of one side of the second mounting portion 212 of the upper frame 21 to improve the sealing performance of the connection between the upper frame 21 and the lower frame 22 on the one hand, and to prevent the upper frame 21 and the lower frame 22 from sliding relative to each other when the box body 1 is placed on the bracket assembly 2 on the other hand.

[0061] The upper frame 21 is also provided with a protrusion 211, which is arranged at one end of the upper frame 21 on the side away from the base 32 toward the moving direction of the second position, and is used to be clamped with the bottom of the washing machine case 1 to fix the case 1. After the bracket assembly 2 composed of the upper frame 21 and the lower frame 22 is installed, the bracket assembly 2 is placed at the bottom of the case 1, and the lifting mechanism 223 is driven by the adjusting mechanism to drive the rolling module 3 to move between the first position and the second position. When the rolling module 3 is in the second position, the bracket assembly 2 is raised until the protrusion 211 of the upper frame 21 is clamped with the bottom of the case 1, and a force is applied to push the case 1 to move, so as to drive the bracket assembly 2 clamped with the case 1 to drive the case 1 to move to the specified position.

[0062] The invention also provides a device which can be applied to a portable and detachable mobile bracket.

[0063] When the portable adjustable and detachable mobile support of the present invention is used, it is determined whether the height of the support assembly 2 is lower than the height of the foot 11 of the washing machine housing 1. When the height of the support assembly 2 is lower than the height of the foot 11 of the washing machine housing 1, the installed support assembly 2 is placed at the bottom of the washing machine housing 1 supported by the foot 11, and the lifting mechanism 223 is driven to move the rolling module 3 between the first position and the second position by providing a force through the adjustment mechanism. When the rolling module 3 is in the first position, the height of the support assembly 2 supported by the rolling module 3 is reduced until the height of the support assembly 2 after the descent is lower than the height of the foot 11 of the housing 1, and the support assembly 2 is placed at the bottom of the washing machine housing 1 supported by the foot 11. When the rolling module 3 is in the second position, the height of the support assembly 2 supported by the rolling module 3 is increased until the height of the support assembly 2 after the rise is higher than the height of the foot 11 of the housing 1. When the housing 1 is lifted, the support assembly 2 contacts the bottom of the washing machine housing 1, providing another force acting on the washing machine housing 1. Since the washing machine housing 1 is engaged with the support assembly 2, the movement of the support assembly 2 drives the washing machine housing 1 to move smoothly to the designated position. The rolling module 3 is controlled to be in the first position again through the adjustment mechanism, and the height of the bracket assembly 2 supported by the rolling module 3 is lowered. The height of the bracket assembly 2 after the lowering is lower than the height of the foot 11 of the case 1. A force is applied to pull out the bracket assembly 2 at the bottom of the case 1, and the bracket assembly 2 is taken out and the upper frame 21 is removed. When the height of the bracket assembly 2 is higher than the height of the foot 11 of the washing machine case 1, the rolling module 3 is controlled to be in the first position through the adjustment mechanism, and the height of the bracket assembly 2 supported by the rolling module 3 is lowered. The height of the bracket assembly 2 after the lowering is lower than the height of the foot 11 of the case 1, and the bracket assembly 2 is placed at the bottom of the washing machine case 1 supported by the foot 11. The subsequent operation steps are the same as the steps when the height of the bracket assembly 2 is lower than the height of the foot 11 of the washing machine case 1, and will not be repeated.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
