Description

Technical Field

[0001] This invention relates to the field of transfer device technology, and in particular to a lifting and moving mechanism. Background Technology

[0002] Household appliances such as washing machines, freezers, and refrigerators are often inconvenient to move due to their large size and weight, requiring both time and effort. Currently, there are two common methods for moving these heavy appliances: using a forklift or manual handling. However, forklifts are usually unsuitable for home environments, and relying solely on manual handling is extremely difficult. Therefore, existing technology proposes a solution: installing a moving bracket at the bottom of the appliance. This bracket is typically equipped with a wrench and casters. Users can lift the appliance off the ground by turning the wrench and then easily drag it using the casters, thus achieving effortless movement.

[0003] Chinese patent document CN223036032U discloses a movable support, including a fixed part, a movable part, a swing arm, and a ramp block. The movable part moves relative to the fixed part. The hinged end of the swing arm and the ramp block are connected to the fixed part and the movable part, respectively. Through the relative movement of the swing arm and the ramp block, after the swing arm rotates, the ramp block cooperates with the roller to raise or lower the roller.

[0004] In the aforementioned prior art, a set of lifting mechanisms needs to be installed at both ends of the fixed bracket, and then the lifting mechanisms at both ends are lifted synchronously through a mechanical linkage component. Since the bracket size is fixed, different sizes need to be manufactured to meet the installation requirements of different types of household appliances, which results in higher production costs and is also more inconvenient for users when selecting and replacing them. Summary of the Invention

[0005] To address the aforementioned problems, this invention discloses a lifting and moving mechanism that uses a switch in conjunction with a hydraulic mechanism to drive rollers to raise or lower the device. This allows for synchronous operation of the lifting mechanisms at both ends without relying on supports or linkage components, thus solving the problem that existing moving supports have fixed dimensions and cannot be applied to various sizes of household appliances.

[0006] The specific technical solution is as follows:

[0007] A lifting and moving mechanism, comprising:

[0008] Lifting mechanisms are installed at both ends of the electrical appliance base plate to lift and move the electrical appliance;

[0009] Infusion tubing is used to deliver hydraulic fluid to each lifting mechanism;

[0010] A hydraulic drive mechanism is used to drive hydraulic medium to be delivered to each lifting mechanism through multiple infusion pipes, so as to drive it to lift or lower.

[0011] Switching assembly used to drive the hydraulic drive mechanism.

[0012] Furthermore, the hydraulic drive mechanism includes at least one hydraulic pump, one end of each hydraulic pump is connected to an infusion pipe via a connector, and the other end of the infusion pipe is connected to a lifting mechanism; each hydraulic pump is equipped with a piston, one end of which is connected to a piston rod, and the other end of the piston rod is driven by a switching assembly.

[0013] Furthermore, it also includes a mounting plate, which includes a first mounting plate and a second mounting plate disposed at both ends of the electrical base plate. The bottom of the first mounting plate and the second mounting plate are respectively provided with at least one lifting mechanism. The hydraulic drive mechanism and the switch assembly are disposed on the first mounting plate.

[0014] Furthermore, the switch assembly includes a first wrench, a connecting rod, and a push block. One end of the first wrench has a first connection point and a second connection point, wherein the second connection point is closer to the end of the first wrench than the first connection point. The first connection point is hinged to the first mounting plate 51, and the second connection point is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to the push block, and one end of the push block is fixedly connected to the ends of two piston rods. When the first wrench is rotated, the first wrench drives the push block and piston rod to move through the connecting rod, and causes the piston in the hydraulic pump to drive the hydraulic medium to be delivered to each lifting mechanism through the infusion pipe.

[0015] Furthermore, the switch assembly includes a second wrench and a push block. One end of the second wrench is provided with a hinge point and is hinged to the first mounting plate 51, and the end of the second wrench extends outward to form a lever portion. One end of the push block is connected and fixed to the ends of two piston rods, and the other end of the push block is fitted against the side wall of one end of the second wrench. When the second wrench is rotated, the second wrench pushes the push block and piston rods to move through the lever portion, and causes the piston in the hydraulic pump to drive the hydraulic medium to be delivered to each lifting mechanism through the infusion pipe.

[0016] Furthermore, the lifting mechanism includes a base, a lifting seat, and rollers. The upper end of the base is fixed to the electrical base plate, and the lower end of the base is open. A connector for connecting an infusion tube is also provided on the outer wall of the base, which is connected to the upper end of its inner cavity. The lifting seat is longitudinally slidably arranged inside the base. The upper end of the lifting seat is closed, and the lower end of the lifting seat is open and allows the rollers to rotate horizontally. The bottom end of the rollers is lower than the bottom end of the lifting seat. At least one receiving groove is provided on the outer wall of the upper end of the lifting seat, and a sealing element that fits tightly against the inner wall of the base is fitted in the receiving groove.

[0017] When the hydraulic medium enters the top of the base cavity through the connector, the hydraulic medium presses down against the lifting seat, causing the lifting seat and rollers to extend downwards, so that the rollers are supported on the ground, thereby lifting the electrical appliance and moving it through the rollers.

[0018] Furthermore, at least two guide blocks are provided on the inner side wall of the base, and at least two guide grooves are longitudinally opened on the outer side wall of the lower end of the lifting seat. The longitudinal sliding connection between the lifting seat and the base is realized by the cooperation of the guide grooves and guide blocks, and the upper end of the guide groove is closed and limits the movement of the guide block.

[0019] Furthermore, the lifting mechanism includes a base, a lifting sleeve, a lifting seat, and rollers. The upper end of the base is fixed to the electrical base plate, and the lower end of the base is open. A connector for connecting an infusion tube is also provided on the outer wall of the base, which is connected to the upper end of its inner cavity. The lifting sleeve is longitudinally slidably arranged inside the base, with openings at both the upper and lower ends. The lifting seat is longitudinally slidably arranged inside the lifting sleeve, with a closed upper end and an open lower end. The rollers are horizontally rotatable, with the bottom end of the rollers lower than the bottom end of the lifting seat. At least one receiving groove is provided on the upper outer wall of both the lifting sleeve and the lifting seat, and a sealing element is fitted in the receiving groove. The sealing element on the lifting sleeve is tightly fitted with the inner wall of the base to achieve a seal, and the sealing element on the lifting seat is tightly fitted with the inner wall of the lifting sleeve to achieve a seal.

[0020] When the hydraulic medium enters the top of the base cavity through the connector, the hydraulic medium presses down against the lifting seat, causing the lifting seat to move downward and drive the lifting sleeve to descend. At this time, the rollers extend downward and support the ground, thereby lifting the electrical appliance and moving it through the rollers.

[0021] Furthermore, a casing is fitted around the base, and at least two guide blocks are provided on the inner wall of the bottom end of the casing and the inner wall of the bottom end of the lifting sleeve. At least two guide grooves are longitudinally formed on the outer wall of the lower end of the lifting sleeve and the outer wall of the lower end of the lifting seat. The longitudinal sliding connection between the lifting sleeve and the base is realized by the cooperation of the guide groove of the lifting sleeve with the guide block of the base; the longitudinal sliding connection between the lifting seat and the lifting sleeve is realized by the cooperation of the guide groove of the lifting seat with the guide block of the lifting sleeve; and the upper end of the guide groove is closed and limits the movement of the guide block.

[0022] Furthermore, the mounting plate, the lifting mechanism, the hydraulic drive mechanism, and the switch assembly are all directly mounted on the electrical base plate.

[0023] The beneficial effects of this invention are reflected in:

[0024] (1) The present invention adopts a switch-controlled hydraulic drive mechanism, which replaces the traditional mechanical support and linkage components, realizes the automatic synchronous operation of the front and rear lifting mechanisms, and ensures that they remain synchronized during operation, eliminating complex structural components and reducing production costs.

[0025] (2) The present invention uses hydraulic drive to make the rollers in the base extend downward smoothly and support the ground, thereby lifting the electrical appliance to a predetermined height. The operation is controlled by only a wrench, which is simple and convenient, effectively reducing the labor intensity of users and realizing labor-saving and efficient movement.

[0026] (3) Compared with the prior art, the present invention does not rely on the overall support structure. Its front and rear lifting mechanisms can be installed independently on the bottom of the appliance, which can flexibly adapt to different sizes and types of household appliances. This design eliminates the need to customize mobile supports for different appliances, effectively reducing production costs. Attached Figure Description

[0048] Example 1

[0049] Please see the appendix Figure 1-5This embodiment provides a lifting and moving mechanism. Two lifting and moving mechanisms are symmetrically arranged on both sides of the electrical appliance's base plate. By using these two mechanisms to lift both sides of the appliance, the entire appliance can be moved. The lifting and moving mechanism includes a lifting mechanism 1, an infusion pipe 2, a hydraulic drive mechanism 3, and a switch assembly 4. Two lifting mechanisms 1 are respectively located at the front and rear ends of one side of the electrical appliance's base plate and are used to lift and move the appliance. Two infusion pipes 2 are used to transport hydraulic medium. Each infusion pipe 2 is connected at both ends to the hydraulic drive mechanism 3 and one lifting mechanism 1, respectively. The hydraulic drive mechanism 3 is used to deliver hydraulic medium through the infusion pipes 2 to each lifting mechanism 1 to drive it to lift or lower. The switch assembly 4 is used to drive the hydraulic drive mechanism 3.

[0050] This embodiment also includes a mounting plate. The lifting mechanism 1, the hydraulic drive mechanism 3, and the switch assembly 4 are all mounted on one side of the electrical base plate via the mounting plate. The fixing method between the lifting mechanism 1 and the hydraulic drive mechanism 3 and the mounting plate includes any one or more of the following: integral integration, screw fixing, adhesive bonding, riveting, and snap-fit ​​connection. The mounting plate includes a first mounting plate 51 and a second mounting plate 52 disposed at the front and rear corners of the electrical base plate. A lifting mechanism 1 is respectively disposed at the bottom of the first mounting plate 51 and the second mounting plate 52. The hydraulic drive mechanism 3 and the switch assembly 4 are also disposed on the first mounting plate 51 located at the front end.

[0051] In this embodiment, through holes are reserved at the corners of the first mounting plate 51 and the second mounting plate 52 for mounting feet, so that electrical appliances can be supported by the feet 53 when stationary.

[0052] In this embodiment, the first and second mounting plates 52, the lifting mechanism 1, the hydraulic drive mechanism 3, and the switch assembly 4 can all be made of metal or plastic.

[0053] In this embodiment, the hydraulic drive mechanism 3 includes two hydraulic pumps 31, which are integrated into the mounting plate and are horizontally arranged and distributed left and right. One end of each hydraulic pump 31 is connected to a fluid inlet pipe 2 via a connector 21, and the other ends of the two fluid inlet pipes 2 are connected to two lifting mechanisms 1 respectively. Each hydraulic pump 31 is equipped with a piston for driving the hydraulic medium. One end of the piston is connected to a piston rod 32, and the other end of the piston rod 32 is driven by a switch assembly 4. The hydraulic medium used in this embodiment can be water or hydraulic oil.

[0054] In this embodiment, the switch assembly 4 includes a first wrench 41, a connecting rod 42, and a push block 43. One end of the first wrench 41 is provided with a first connection point 411 and a second connection point 412. The second connection point 412 is closer to the end of the first wrench 41 than the first connection point 411. The first connection point 411 is hinged to the first mounting plate 51 through a hinge shaft, so that the first wrench 41 can rotate horizontally along the first mounting plate 51. The second connection point 412 is hinged to one end of the connecting rod 42, and the other end of the connecting rod 42 is hinged to the push block 43. One end of the push block 43 is connected and fixed to the ends of the two piston rods 32.

[0055] Before rotation, the first wrench 41 is positioned horizontally. When the first wrench 41 is rotated 90 degrees, the first wrench 41 drives the push block 43 and the piston rod 32 to move through the connecting rod 42, and causes the piston in the hydraulic pump 31 to drive the hydraulic medium to be delivered to the two lifting mechanisms 1 through the infusion pipe 2. At this time, the grip direction of the first wrench 41 is consistent with the direction of the roller 13, so that the household appliances can be moved back and forth by pulling or pushing the two first wrenches 41.

[0056] In this embodiment, the first mounting plate 51 has elongated grooves 511 on both sides of the push block 43. The grooves 511 are arranged along the movement direction of the push block 43. The bottom of both sides of the push block 43 are respectively provided with wing plates 431 extending to the grooves 511. Fasteners are used to longitudinally penetrate the grooves 511 and the wing plates 431 to guide the movement of the push block 43.

[0057] In this embodiment, the lifting mechanism 1 includes a base 11, a lifting seat 12, and rollers 13. The upper end of the base 11 is fixed to the mounting plate, and the lower end of the base 11 is open. A connector 21 for connecting the infusion tube 2 is also provided on the outer wall of the base 11, and the connector 21 is connected to the upper end of its inner cavity. The lifting seat 12 is longitudinally slidably arranged inside the base 11. The upper end of the lifting seat 12 is closed, and the lower end of the lifting seat 12 is open and equipped with rollers 13. The two ends of the rollers 13 horizontally penetrate the two side walls of the lifting seat 12, realizing the rotatable connection between the rollers 13 and the lifting seat 12. The bottom end of the rollers 13 is lower than the horizontal position of the bottom end of the lifting seat 12. A receiving groove 123 is provided on the outer wall of the upper end of the lifting seat 12. A sealing element 124 that fits tightly against the inner wall of the base 11 is sleeved in the receiving groove 123 to ensure the sealing of the upper and lower ends of the side wall of the lifting seat 12 and to prevent leakage of hydraulic medium from affecting the lifting of the driving rollers 13.

[0058] The hydraulic drive mechanism 3 is driven by the switch assembly 4 to pump the hydraulic medium into the top of the base 11. As the hydraulic medium in the base gradually increases and pushes the lifting seat downward, the lifting seat 12 and the roller 13 move downward and lift the electrical appliance.

[0059] In this embodiment, the base 11 is integrated on the mounting plate. A sleeve 101 is installed on the outside of the base 11 by fasteners. The bottom end of the sleeve 101 abuts against the bottom end of the base 11. Four guide blocks 111 extending horizontally inward are evenly distributed on the inner wall of the bottom end of the sleeve 101. Four corresponding guide grooves 121 are longitudinally opened on the outer wall of the lower end of the lifting seat 12. The longitudinal sliding connection between the lifting seat 12 and the base 11 is realized by the cooperation of the guide grooves 121 and the guide blocks 111. The upper end of the guide grooves 121 is closed and limits the movement of the guide blocks 111.

[0060] In this embodiment, the top of the lifting seat 12 is provided with several protrusions 122. The bottom of the protrusions 122 is not higher than the joint 21 on the outer wall of the base 11. The protrusions 122 are used to prevent the top of the lifting seat 12 from fitting with the top of the inner cavity of the base 11, so as to ensure that there is a sufficient gap between the top of the lifting seat 12 and the top wall of the inner cavity of the base 11, so as to ensure that the hydraulic medium can push the lifting seat 12.

[0061] By pulling the first wrench 41 outward, the first wrench 41 pushes the push block 43 and piston rod 32 forward through the connecting rod 42. At this time, the hydraulic medium enters the top of the inner cavity of the base 11 through the connector 21 under the drive of the hydraulic pump 31. The hydraulic medium presses the lifting seat 12 downward, causing the lifting seat 12 and the roller 13 to extend downward, so that the roller 13 supports the ground, thereby lifting the electrical appliance and moving it through the roller 13.

[0062] When the first wrench 41 is pushed inward, the first wrench 41 pulls the push block 43 and the piston rod 32 backward through the connecting rod 42. At this time, the hydraulic medium returns to the hydraulic pump 31 through the infusion pipe 2 under the suction of the hydraulic pump 31. At the same time, the electrical appliance is pressed down by gravity, causing the lifting seat 12 to retract into the base 11. The bottom of the roller 13 in the base 11 is not lower than the horizontal position of the bottom end of the base 11, and the bottom end of the sleeve 101 on the base 11 is not lower than the horizontal position of the bottom end of the electrical appliance support foot, so that the electrical appliance is supported by the support foot when it is stationary.

[0063] Example 2

[0064] The difference between this embodiment and Embodiment 1 is that the lifting mechanism 1, the hydraulic drive mechanism 3, and the switch assembly 4 are all directly mounted on the electrical base plate. This eliminates the need for a subsequent mounting plate installation step, improving the ease of moving the electrical appliance.

[0065] Example 3

[0066] like Figure 6-7As shown, the difference between this embodiment and embodiment 1 is that the switch assembly 4 includes a second wrench 44 and a push block 43. One end of the second wrench 44 is provided with a hinge point 441 and is hinged to the first mounting plate 51. The end of one end of the second wrench 44 extends outward to form a lever part 442. The side wall of the lever part 442 transitions from an arc surface to a plane. One end of the push block 43 is connected and fixed to the ends of the two piston rods 32. The other end of the push block 43 is fitted against the side wall of one end of the second wrench 44. When the second wrench 44 is rotated, the second wrench 44 pushes the push block 43 and the piston rods 32 to move through the lever part 442. The push block 43 is directly pushed by lever principle, and the piston in the hydraulic pump 31 drives the hydraulic medium to be delivered to each lifting mechanism 1 through the infusion pipe 2.

[0067] Before rotation, the second wrench 44 is also positioned horizontally. When the second wrench 44 is rotated 90 degrees, the second wrench 44 pushes the push block 43 and the piston rod 32 through its lever part 442, and causes the piston in the hydraulic pump 31 to drive the hydraulic medium to be delivered to the two lifting mechanisms 1 through the infusion pipe 2. At this time, the grip direction of the second wrench 44 is consistent with the direction of the roller 13, so that the household appliance can be moved back and forth by pulling forward or pushing the two second wrenches 44 backward.

[0068] To ensure the stability of the second wrench 44 when it rotates, the top of the push block 43 near one end of the second wrench 44 is provided with a baffle 432. The bottom of the baffle 432 is in contact with the top of one end of the second wrench 44, thereby positioning the second wrench 44 and ensuring that its lever part 442 is always in contact with the side wall of one end of the push block 43.

[0069] Example 4

[0070] like Figure 8-11 As shown, to meet the lifting height requirements of different electrical appliances, this embodiment differs from Embodiment 1 in that: the lifting mechanism 1 includes a base 11, a lifting sleeve 14, a lifting seat 12, and rollers 13. The upper end of the base is fixed to the bottom of the first mounting plate 51, and the lower end of the base 11 is open. A connector 21 for connecting the infusion tube 2 is also provided on the outer wall of the base 11, which is connected to the upper end of its inner cavity; the lifting sleeve 14 is longitudinally slidably arranged inside the base 11, and both the upper and lower ends of the lifting sleeve are open. The lifting seat 12 is slidably arranged, with its upper end closed and its lower end open. The roller 13 is horizontally rotatable and its bottom end is lower than that of the lifting seat 12. The upper outer walls of the lifting sleeve 14 and the lifting seat are each provided with at least one accommodating groove 123. A sealing element 124 is fitted in the accommodating groove 123. The sealing element 124 on the lifting sleeve 14 is tightly fitted with the inner wall of the base to achieve a seal. The sealing element 124 on the lifting seat 12 is also tightly fitted with the inner wall of the lifting sleeve to achieve a seal.

[0071] When the hydraulic medium enters the top of the inner cavity of the base 11 through the connector 21, the hydraulic medium presses down against the lifting seat 12, causing the lifting seat 12 to move downward and drive the lifting sleeve 14 to descend. At this time, the roller 13 extends downward and supports the ground, thereby lifting the electrical appliance and moving it through the roller 13.

[0072] In this embodiment, a housing 101 is fitted onto the outer side of the base 11. Four guide blocks 111 are evenly distributed on the inner wall of the bottom end of the housing 101 and on the inner wall of the bottom end of the lifting sleeve 14. Four corresponding guide grooves 121 are longitudinally formed on the outer wall of the lower end of the lifting sleeve 14 and the outer wall of the lower end of the lifting seat 12. The longitudinal sliding connection between the lifting sleeve 14 and the base is realized by the cooperation between the guide grooves 121 of the lifting sleeve 14 and the guide blocks 111 of the base. The longitudinal sliding connection between the lifting seat 12 and the lifting sleeve 14 is realized by the cooperation between the guide grooves 121 of the lifting seat and the guide blocks 111 of the lifting sleeve 14. The upper end of the guide groove is closed and limits the movement of the guide blocks 111.

[0073] In this embodiment, the top of both the lifting seat 12 and the lifting sleeve 14 is provided with a number of protrusions 122. The protrusions 122 are used to prevent the top of the lifting seat 12 and the lifting sleeve 14 from fitting with the top of the inner cavity of the base 11, so as to ensure that there is a sufficient gap between the top of the lifting seat 12 and the top wall of the inner cavity of the base 11.

[0074] In this embodiment, by adding a lifting sleeve 14 to the lifting mechanism 1, the extension length of the roller 13 is extended, thereby increasing the lifting height of the lifting mechanism 1 on the electrical appliances and meeting the height requirements of different electrical appliances.

[0075] Example 5

[0076] like Figure 12-13 As shown, the difference between this embodiment and Embodiment 4 is that the two lifting and moving mechanisms are symmetrically arranged on a movable base 6. The movable base 6 has a rectangular frame structure and includes four support seats 61 distributed at the four corners and a connecting rod 62 for connecting two adjacent support seats 61. The support seat 61 is sleeved on one end of the connecting rod 62 and can be telescopically adjusted. The support seat 61 is positioned by fasteners passing through and pressing against the connecting rod 62.

[0077] The lifting mechanism 1, the hydraulic drive mechanism 3, and the switch assembly 4 are respectively fixed to the support base 61 by screws and fasteners with the first mounting plate 51 or the second mounting plate 52. The two first mounting plates 51 are respectively disposed on the support bases 61 on both sides of the front end of the movable base 6, and the two second mounting plates 52 are respectively disposed on the support bases 61 on both sides of the rear end of the movable base 6. By providing lifting and moving structures on both sides of the bottom of the movable base 6, it can be used to support large objects.

[0078] Example 6

[0079] The difference between this embodiment and Embodiment 1 is that the hydraulic drive mechanism 3 includes a hydraulic pump. One end of the hydraulic pump 31 is connected to a delivery pipe 2 via a connector 21, and the other end of the delivery pipe 2 is connected to two branch pipes via a three-way connector. The two branch pipes are respectively connected to two lifting mechanisms. By using a three-way connector for the delivery pipe, hydraulic power can be provided to the two lifting mechanisms through a single hydraulic pump.

[0080] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
