[0023] Reference Figure 1-Figure 7 , which is the first embodiment of the equipment leveling structure of the present invention, the equipment leveling structure includes a supporting component 100, a double-threaded bolt 200 and a connecting and fixing component 300.

[0024] The support component 100 is used to support the equipment and support the equipment on the work platform. The support component 100 in this embodiment includes a bottom wheel assembly 110, and the bottom wheel assembly 110 specifically includes a bottom wheel mounting seat 111 and a rotatable bottom wheel 112 mounted on the bottom wheel mounting seat 111. A stud 130 is vertically arranged on the top of the bottom wheel mounting seat 111. The stud 130 can be an integral structure with the bottom wheel mounting seat 111, or the two components can be fixedly connected by welding or the like.

[0025] See also Figure 3, the outer wall of the double-threaded bolt 200 has an external thread 200a; the interior of the double-threaded bolt 200 has an axial channel, and the inner wall of the axial channel has an internal thread 200b. Among them, the external thread 200a of the double-threaded bolt 200 is opposite to the rotation direction of the internal thread 200b. The stud 130 passes through the axial channel, and the external thread of the stud 130 cooperates with the internal thread 200b of the double-threaded bolt 200. In this embodiment, the external thread 200a of the double-threaded bolt 200 is a left-handed thread, and the internal thread 200b of the double-threaded bolt 200 is a right-handed thread. The double-threaded bolt 200 has a head and a rod, the rod has an external thread 200a, and the axial channel runs through the head and the rod. The double-threaded bolt 200 is preferably a hexagonal head bolt, which is convenient for operation with tools.

[0026] The connecting and fixing component 300 is used to connect with the bottom of the device to assemble the device leveling structure on the device. The connecting and fixing component 300 is arranged above the supporting component 100, and has a mounting hole 311, and the mounting hole 311 has an internal thread. The double-threaded bolt 200 passes through the mounting hole 311, and the external thread 200a of the double-threaded bolt 200 cooperates with the internal thread of the mounting hole 311.

[0027] In this embodiment, the internal thread 200b of the double-threaded bolt 200 and the external thread of the stud 130 are right-handed threads, and the external thread 200a of the double-threaded bolt 200 and the internal thread of the connecting and fixing component 300 are left-handed threads.

[0028] According to the basic principle of thread: For right-hand thread, turn it in clockwise and turn it out counterclockwise, which means "turn clockwise to tighten and counterclockwise to loosen".

[0029] For left-hand thread, turn it counterclockwise to screw it in and turn it clockwise to screw it out, which means "turn clockwise to loosen and counterclockwise to tighten".

[0030] The working principle of the leveling structure is as follows: The double-threaded bolt 200 and the bottom wheel assembly 110 are assembled into an assembly in advance, and the double-threaded bolt 200 is installed in the mounting hole 311 of the connecting and fixing component 300. The double-threaded bolt 200 is turned clockwise to complete the assembly and reach the initial state. At this time, the connecting and fixing component 300 is in the lowest position, such as Figure 4 shown.

[0031] The double-threaded bolt 200 is turned counterclockwise, and the internal thread of the double-threaded bolt 200 plays the role of a nut ("reverse loosening"), and moves upward relative to the stud 130, and the upward movement distance is L1. Figure 6 and Figure 7 shown.

[0032] At the same time, for the external thread of the double-threaded bolt 200 and the internal thread of the connecting and fixing component 300, because both are left-hand threads, the internal thread of the connecting and fixing component 300 plays the role of a nut ("reverse looseness"), and moves upward relative to the double-threaded bolt 200, and the upward movement distance is L2. Figure 6 and Figure 7 shown.

[0033] Therefore, the distance L3 raised by the connecting and fixing component 300 = L1 + L2, achieving the effect of raising the device.

[0034] It should be noted that when the double-threaded bolt 200 rotates counterclockwise for one circle, the double-threaded bolt 200 moves upward for one circle relative to the stud 130, and the connecting and fixing component 300 moves upward for one circle relative to the double-threaded bolt 200. That is, when the double-threaded bolt 200 rotates counterclockwise for one circle, the distance L by which the connecting and fixing component 300 rises is L= ph1+ ph2 (where ph1 is the internal thread lead of the double-threaded bolt 200; ph2 is the external thread lead of the double-threaded bolt 200).

[0035] In another embodiment, the rotation directions of the internal thread and the external thread of the double-threaded bolt 200 are interchanged, that is, the internal thread of the double-threaded bolt 200 is a left-handed thread, and the external thread is a right-handed thread. The corresponding internal thread of the connecting and fixing component 300 is a right-handed thread, and the external thread of the stud 130 is a left-handed thread. At this time, the double-threaded bolt 200 needs to be twisted clockwise to achieve the effect of adjusting the equipment higher.

[0036] The above-mentioned equipment leveling structure adopts a hollow internal and external double-threaded bolt 200, and a thread structure with opposite internal and external threads, in conjunction with the stud 130 of the support component 100 and the internal thread of the connecting and fixing component 300, to realize the vertical lifting function of the bottom support component 100, and the adjustment does not affect the installation angle of the support component 100; it has a simple structure and low cost; it is easy to operate, and can be completed by one person with the help of tools, with high work efficiency. The equipment leveling structure can be applied to a variety of equipment and a variety of scenarios to realize the vertical lifting function.

[0037] In this embodiment, the equipment leveling structure further includes a locking nut 400, which is sleeved on the stud 130 and located at the lower side of the double-threaded bolt 200. The locking nut 400 plays a role in preventing the double-threaded bolt 200 from loosening under external forces such as vibration. Figure 5 , it is necessary to first place the anti-loosening nut 400 at the root of the stud 130 to release the anti-loosening effect, and then tighten the double-threaded bolt 200 for adjustment.

[0038] See also Figure 2 In this embodiment, a pre-positioning structure is also provided between the supporting component 100 and the connecting and fixing component 300 .

[0039] The pre-positioning structure specifically includes a positioning groove 320 provided on the connecting and fixing component 300 and a positioning member 140 provided on the supporting component 100. The positioning member 140 may be a plate-like structure or a columnar structure. The positioning member 140 is provided in the positioning groove 320 and slides up and down along the positioning groove 320 during the lifting process of the bottom wheel assembly 110.

[0040] During assembly, the double-threaded bolt 200 and the bottom wheel assembly 110 are assembled into an assembly in advance, and the assembly can be pre-installed on the connecting and fixing component 300 using the pre-positioning structure, and then the double-threaded bolt 200 is screwed to complete the assembly. During the adjustment process, the positioning member 140 slides up and down along the positioning groove 320, and the pre-positioning structure can play a guiding and fixing role.

[0041] In this embodiment, two positioning members 140 are provided, which are symmetrically arranged on both sides of the stud 130, so as to better play the role of positioning and guiding.

[0042] The connecting and fixing component 300 is a plate-like structure, and a protruding sleeve structure 310 is provided along the upper surface or the lower surface of the connecting and fixing component 300, and the hollow channel of the sleeve structure 310 forms a mounting hole 311. The connecting and fixing component 300 can be fixed to the bottom of the device by a structure such as a screw. In another embodiment, the connecting and fixing component 300 can also be a part of the device, such as a device base.

[0043] In this embodiment, the head of the double-threaded bolt 200 is located at the lower side of the connecting and fixing component 300. When the leveling structure is in the initial state (the connecting and fixing component 300 is at the lowest position), the head of the double-threaded bolt 200 abuts against the bottom surface of the connecting and fixing component 300. The head of the double-threaded bolt 200 is located at the lower side of the connecting and fixing component 300, which is convenient for adjustment operation from the outside. In other embodiments, when the head of the double-threaded bolt 200 is located at the upper side of the connecting and fixing component 300, it may be necessary to operate inside the device.

[0044] In this embodiment, the lead of the external thread of the double-threaded bolt 200 is equal to the lead of the internal thread of the double-threaded bolt 200, that is, when the double-threaded bolt 200 rotates counterclockwise for one circle, the double-threaded bolt 200 moves upward for one circle relative to the stud 130, the connecting and fixing component 300 moves upward for one circle relative to the double-threaded bolt 200, and the connecting and fixing component 300 moves upward for two circles relative to the supporting component 100, that is, it moves upward by double distance, achieving the effect of lifting the equipment. The external thread and internal thread of the double-threaded bolt 200 can be single-thread or double-thread.

[0045] The assembly and working process of the equipment leveling structure of this embodiment are specifically as follows: like Figure 2The double-threaded bolt 200 and the bottom wheel assembly 110 are assembled into an assembly in advance, and then the assembly is pre-installed on the connecting and fixing component 300 using the pre-positioning structure, and the double-threaded bolt 200 is turned clockwise to complete the assembly. Figure 4 shown.

[0046] like Figure 5 As shown, the anti-loosening nut 400 is placed at the root of the stud 130 to release the anti-loosening effect. Then the double-threaded bolt 200 is turned counterclockwise, and the double-threaded bolt 200 moves upward relative to the stud 130. At the same time, the connecting and fixing component 300 also moves upward relative to the double-threaded bolt 200, as shown in FIG. Figure 6 shown.

[0047] The distance L that the double-threaded bolt 200 rotates inversely for one circle and the connecting and fixing component 300 moves upward is = ph1 + ph2, where ph1 is the internal thread lead of the double-threaded bolt 200 and ph2 is the external thread lead of the double-threaded bolt 200.

[0048] When the required position is reached, the anti-loosening nut 400 is set upwardly against the head of the double-threaded bolt 200.

[0049] This embodiment also includes a clothing processing device, which can be a washing machine, a dishwasher, a shoe washing machine, a clothes dryer, etc. In particular, when the device is an embedded or drawer-type structure, the bottom wheel assembly also has a guiding sliding function, and the above-mentioned device leveling structure can realize the vertical lifting function without affecting the installation angle of the bottom wheel and its guiding function. It should be pointed out that the device leveling structure in this embodiment can also be applied to any product equipment that needs to be lifted and leveled, and has universal applicability.

[0050] Embodiment 2 Reference Figure 8 , which is the second embodiment of the equipment leveling structure of the present invention, and the difference between this embodiment and the first embodiment is that the supporting component structure is different. Specifically, the equipment leveling structure in this embodiment includes a supporting component 100, a double-threaded bolt 200 and a connecting and fixing component 300.

[0051] The support component 100 is used to support the device and support the device on the work platform. The support component 100 in this embodiment includes a foot 120, and a stud 130 is vertically arranged on the top of the foot 120. The stud 130 can be an integral structure with the foot 120, or the two components can be fixedly connected by welding, threaded connection, etc.

[0052] The outer wall of the double-threaded bolt 200 has an external thread; the interior of the double-threaded bolt 200 has an axial channel, and the inner wall of the axial channel has an internal thread. Among them, the external thread of the double-threaded bolt 200 is opposite to the rotation direction of the internal thread. The stud 130 passes through the axial channel, and the external thread of the stud 130 cooperates with the internal thread of the double-threaded bolt 200. In this embodiment, the external thread of the double-threaded bolt 200 is a left-handed thread, and the internal thread of the double-threaded bolt 200 is a right-handed thread. The double-threaded bolt 200 has a head and a rod, the rod has an external thread, and the axial channel runs through the head and the rod. The double-threaded bolt 200 is preferably a hexagonal head bolt, which is convenient for operation with tools.

[0053] The connecting and fixing component 300 is used to connect with the bottom of the device to assemble the device leveling structure on the device. The connecting and fixing component 300 is arranged above the supporting component 100, and has a mounting hole 311, and the mounting hole 311 has an internal thread. The double-threaded bolt 200 passes through the mounting hole 311, and the external thread of the double-threaded bolt 200 cooperates with the internal thread of the mounting hole 311.

[0054] In this embodiment, the internal thread of the double-threaded bolt 200 and the external thread of the stud 130 are right-handed threads, and the external thread of the double-threaded bolt 200 and the internal thread of the connecting and fixing component 300 are left-handed threads.

[0055] According to the basic principle of thread: For right-hand thread, turn it in clockwise and turn it out counterclockwise, which means "turn clockwise to tighten and counterclockwise to loosen".

[0056] For left-hand thread, turn it counterclockwise to screw it in and turn it clockwise to screw it out, which means "turn clockwise to loosen and counterclockwise to tighten".

[0057] The working principle of the leveling structure is as follows: The double-threaded bolt 200 and the base 120 are assembled into an assembly in advance, and the double-threaded bolt 200 is installed in the installation hole 311 of the connecting and fixing component 300. The double-threaded bolt 200 is turned clockwise to complete the assembly and reach the initial state. At this time, the connecting and fixing component 300 is in the lowest position.

[0058] The double-threaded bolt 200 is turned counterclockwise, and the internal thread of the double-threaded bolt 200 plays the role of a nut ("reverse loosening"), and moves upward relative to the stud 130.

[0059] For the external thread of the double-threaded bolt 200 and the internal thread of the connecting and fixing component 300, since both are left-hand threads, the internal thread of the connecting and fixing component 300 plays the role of a nut ("reverse looseness") and moves upward relative to the double-threaded bolt 200.

[0060] When the double-threaded bolt 200 rotates counterclockwise for one circle, the double-threaded bolt 200 moves upward for one circle relative to the stud 130, and the connecting and fixing component 300 moves upward for one circle relative to the double-threaded bolt 200, thereby achieving the effect of lifting the equipment.

[0061] The distance L that the double-threaded bolt 200 is raised by rotating the double-threaded bolt 200 in the opposite direction and the connecting and fixing component 300 is equal to ph1+ph2, where ph1 is the internal thread lead of the double-threaded bolt 200 and ph2 is the external thread lead of the double-threaded bolt 200.

[0062] It should be pointed out that in another embodiment, the rotation direction of the internal thread and the external thread of the double-threaded bolt 200 are interchanged, that is, the internal thread of the double-threaded bolt 200 is a left-handed thread, and the external thread is a right-handed thread, the corresponding internal thread of the connecting and fixing component 300 is a right-handed thread, and the external thread of the stud 130 is a left-handed thread. At this time, the double-threaded bolt 200 needs to be twisted clockwise to achieve the effect of adjusting the equipment higher.

[0063] In this embodiment, the equipment leveling structure further includes a locking nut 400, which is sleeved on the stud 130 and located at the lower side of the double-threaded bolt 200. The locking nut 400 plays a role in preventing the double-threaded bolt 200 from loosening under external forces such as vibration. When adjustment is required, the locking nut 400 needs to be placed at the root of the stud 130 to release the locking effect, and then the double-threaded bolt 200 is screwed for adjustment.

[0064] In this embodiment, a pre-positioning structure is further provided between the supporting component 100 and the connecting and fixing component 300 .

[0065] The pre-positioning structure specifically includes a positioning groove 320 provided on the connecting and fixing component 300 and a positioning member 140 provided on the supporting component 100. The positioning member 140 may be a plate-like structure or a columnar structure. The positioning member 140 is provided in the positioning groove 320 and slides up and down along the positioning groove 320 during the lifting and lowering process of the base 120.

[0066] During assembly, the double-threaded bolt 200 and the foot 120 are assembled into an assembly in advance, and the assembly can be pre-installed on the connecting and fixing component 300 using the pre-positioning structure, and then the double-threaded bolt 200 is screwed to complete the assembly. During the adjustment process, the positioning member slides up and down along the positioning groove, and the pre-positioning structure can play a guiding and fixing role.

[0067] In this embodiment, two positioning members are provided, which are symmetrically arranged on both sides of the stud 130, so as to better play the role of positioning and guiding.

[0068] The connecting and fixing component 300 is a plate-like structure, and a protruding sleeve structure 310 is provided along the upper surface or the lower surface of the connecting and fixing component 300, and the hollow channel of the sleeve structure 310 forms a mounting hole 311. The connecting and fixing component 300 can be fixed to the bottom of the device by a structure such as a screw. In another embodiment, the connecting and fixing component 300 can also be a part of the device, such as a device base.

[0069] In this embodiment, the head of the double-threaded bolt 200 is located at the lower side of the connecting and fixing component 300. When the leveling structure is in the initial state (the connecting and fixing component 300 is at the lowest position), the head of the double-threaded bolt 200 abuts against the bottom surface of the connecting and fixing component 300. The head of the double-threaded bolt 200 is located at the lower side of the connecting and fixing component 300, which is convenient for adjustment operation from the outside. In other embodiments, when the head of the double-threaded bolt 200 is located at the upper side of the connecting and fixing component 300, it may be necessary to operate inside the device.

[0070] In this embodiment, the lead of the external thread of the double-threaded bolt 200 is equal to the lead of the internal thread of the double-threaded bolt 200, that is, when the double-threaded bolt 200 rotates counterclockwise for one circle, the double-threaded bolt 200 moves upward for one circle relative to the stud 130, the connecting and fixing component 300 moves upward for one circle relative to the double-threaded bolt 200, and the connecting and fixing component 300 moves upward for two circles relative to the supporting component 100, that is, it moves upward by double the distance, thereby achieving the effect of lifting the equipment.

[0071] The assembly and working process of the equipment leveling structure of this embodiment are specifically as follows: The double-threaded bolt 200 and the foot 120 are assembled into an assembly in advance, and then the assembly is pre-installed on the connecting and fixing component 300 using a pre-positioning structure, and the double-threaded bolt 200 is turned clockwise to complete the assembly.

[0072] The anti-loosening nut 400 is placed at the root of the stud 130 to release the anti-loosening effect. Then the double-threaded bolt 200 is turned counterclockwise, and the double-threaded bolt 200 moves upward relative to the stud 130. At the same time, the connecting and fixing component 300 also moves upward relative to the double-threaded bolt 200.

[0073] The distance L that the double-threaded bolt 200 rotates inversely for one circle and the connecting and fixing component 300 moves upward is = ph1 + ph2, where ph1 is the internal thread lead of the double-threaded bolt 200 and ph2 is the external thread lead of the double-threaded bolt 200.

[0074] When the required position is reached, the anti-loosening nut 400 is set upwardly against the head of the double-threaded bolt 200.

[0075] The equipment leveling structure of this embodiment is suitable for situations where the equipment needs to be fixed on the use platform. The equipment is fixed on the use platform through the base 120. Through the above-mentioned equipment leveling structure, the equipment can be lifted vertically without rotating the base 120, thereby realizing the lifting and leveling functions.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
