Description

Technical Field

[0001] This invention relates to the field of jack technology, and more specifically to a magnetic energy jack. Background Technology

[0002] A jack is a tool for lifting heavy objects. It is frequently used in fields such as automobile repair and construction. Jacks amplify small input forces through mechanical flow or fluid pressure transmission to lift or support heavy objects.

[0003] Traditional mechanical jacks rely on manual rotation of the handle, which is time-consuming and laborious, and their threaded transmission efficiency is low. After long-term use, the O-rings and oil seals of traditional hydraulic jacks will harden and wear, posing a risk of hydraulic oil leakage, which will eventually lead to a decrease in lifting capacity and oil leakage that pollutes the environment. In contrast, magnetic energy is a clean energy source that can be reused for a long time, and its use is environmentally friendly and will not pollute the environment.

[0004] Therefore, providing a time-saving, labor-saving, environmentally friendly, and pollution-free magnetic jack that uses magnetic energy to lift heavy objects is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a magnetic energy jack that solves the technical problems of existing mechanical jacks being time-consuming and laborious to use, and hydraulic jacks causing oil leakage and environmental pollution after long-term use.

[0006] To achieve the above objectives, the invention adopts the following technical solution:

The middle lifting assembly includes a middle fixing sleeve and a middle lifting housing. The middle fixing sleeve is fixed to the top of the first mounting housing, and the middle lifting housing slides through the middle fixing sleeve. The first magnet is fixed to the inner bottom of the middle lifting housing and is arranged opposite to the first driving magnet. The magnetic properties of the opposing surfaces of the first magnet and the first driving magnet are the same, causing the middle lifting housing to rise under magnetic force. The first stopper moves to change the magnetic flux between the first driving magnet and the second magnet, thereby changing their magnetic properties. The repulsive force between them; the second driving magnet is fixed to the inner top of the middle lifting housing; the second shielding mechanism includes a second mounting housing and a second blocker, the second mounting housing is fixed to the outer top of the middle lifting housing, and the second blocker can move horizontally to fully or partially open or close the magnetic path of the second driving magnet; the upper lifting assembly includes an upper fixing sleeve and an upper lifting housing, the upper fixing sleeve is fixed to the outer top of the second mounting housing, and the upper lifting housing slides through the upper fixing sleeve; the second magnet is fixed to the inner bottom of the upper lifting housing and is arranged opposite to the second driving magnet, the magnets on the opposite surfaces of the second magnet and the second driving magnet have the same magnetism, causing the upper lifting housing to rise under the action of magnetic force, and the second blocker moves to change the magnetic flux between the second driving magnet and the second magnet, thereby changing the repulsive force between them; the pusher is fixed to the outer top of the upper lifting housing, and the upper lifting housing rises to push the pusher to lift the heavy object.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] See appendix Figure 1 To be continued Figure 4A magnetic jack according to an embodiment of the invention includes a lower magnetic shell 01, a first driving magnet 02, a first shielding mechanism 03, a middle lifting assembly 04, a first magnet 05, a second driving magnet 06, a second shielding mechanism 07, an upper lifting assembly 08, a second magnet 09, and a pushing component 10; the first driving magnet 02 is installed inside the lower magnetic shell 01; the first shielding mechanism 03 includes a first mounting housing 031 and a first blocker 034, the first mounting housing 031 is fixed to the top of the lower magnetic shell 01, and the first blocker 034 can move horizontally to fully or partially open or close. The magnetic path of the drive magnet 02 is closed; the middle lifting assembly 04 includes a middle fixing sleeve 041 and a middle lifting housing 042. The middle fixing sleeve 041 is fixed to the top of the first mounting housing, and the middle lifting housing 042 slides inside the middle fixing sleeve 041; the magnet 05 is fixed to the inner bottom of the middle lifting housing 042 and is arranged opposite to the drive magnet 02. The magnets 05 and the drive magnet 02 have the same magnetism, causing the middle lifting housing 042 to rise under the action of magnetic force. The first stopper 034 moves to change the relationship between the drive magnet 02 and the magnet 05. The magnetic flux between them changes the repulsive force between them; the second driving magnet 06 is fixed to the inner top of the middle lifting housing 042; the second shielding mechanism 07 includes a second mounting housing 071 and a second blocker 074, the second mounting housing 071 is fixed to the outer top of the middle lifting housing 042, and the second blocker 074 can move horizontally to fully or partially open or close the magnetic path of the second driving magnet 06; the upper lifting assembly 08 includes an upper fixing sleeve 081 and an upper lifting housing 082, the upper fixing sleeve 081 is fixed to the outer top of the second mounting housing 071. The upper lifting housing 082 is slidably inserted into the upper fixed sleeve 081; the second magnet 09 is fixed on the inner bottom of the upper lifting housing 082 and is arranged opposite to the second driving magnet 06. The magnetism of the opposite surfaces of the second magnet 09 and the second driving magnet 06 is the same, which makes the upper lifting housing 082 rise under the action of magnetic force. The second stopper 074 moves to change the magnetic flux between the second driving magnet 06 and the second magnet 09, thereby changing the repulsive force between them; the pusher 10 is fixed on the outer top of the upper lifting housing 082. The upper lifting housing 082 rises and pushes the pusher 10 to lift the heavy object.

[0028] The present invention discloses a magnetic energy jack. A first stopper 034 moves horizontally between a driving magnet 02 and a magnet 05 to open and close the magnetic path between them, thereby controlling the magnitude of the magnetic flux between the driving magnet 02 and the magnet 05, and thus controlling the repulsive force between the driving magnet 02 and the magnet 05. Under the action of magnetic repulsion, the magnet 05 can drive the middle lifting shell 042 to rise. Similarly, a second stopper 074 moves horizontally between a driving magnet 06 and a magnet 09 to open and close the magnetic path between them, thereby controlling the magnitude of the magnetic flux between the driving magnet 06 and the magnet 09, and thus controlling the repulsive force between the driving magnet 06 and the magnet 09. Under the action of magnetic repulsion, the magnet 09 can drive the upper lifting shell 082 to rise. The rise of the upper lifting shell 082 can drive the jacking member 10 to lift the heavy object. The present invention ultimately achieves the lifting of the heavy object through magnetic energy.

[0029] Specifically, protective shells are fixedly fitted around the drive magnet 102, magnet 105, drive magnet 206, magnet 209, drive magnet 315, and magnet 316.

[0030] like Figure 1 As shown, the opposing magnetic poles of drive magnet 02 and magnet 05 are the same (N pole), the opposing magnetic poles of drive magnet 06 and magnet 09 are the same (N pole), and the opposing magnetic poles of magnet 05 and drive magnet 06 are the same (S pole).

[0031] It should be noted that this jack uses an iron stopper and a magnetic stopper. The two magnets used in the iron stopper and the magnetic stopper can be either traditional magnets or new types of magnets.

[0032] like Figure 6 As shown, a traditional magnet has 6 magnetic poles, namely 3 N poles and 3 S poles. Traditional magnets with this polarity can be rectangular, square, cylindrical, arc-shaped and other various shapes.

[0033] like Figure 7 As shown, the new magnet has 6 magnetic poles, namely 1 S pole and 5 N poles or 1 N pole and 5 S poles. The new magnet has rectangular, square, arc, cylindrical and many other shapes.

[0034] In some embodiments, the first shielding mechanism 03 further includes a first fixed shaft 032, a first sliding block 033, a core wire puller 035, and a first return spring 037; there are two first fixed shafts 032, which are parallel to each other and both are fixed inside the first mounting housing 031; there are two first sliding blocks 033, which are respectively slidably disposed on the two first fixed shafts 032, and a first stopper 034 is fixed between the two first sliding blocks 033; the core wire puller 035 is arranged outside the first mounting housing 031, and the working end of the core wire puller 035 is connected to the first stopper 034 through a first core wire 036; by pulling the first core wire 036 through the core wire puller 035, the first stopper 034 can slide on the first fixed shaft 032; the first return spring 037 is sleeved on the first fixed shaft 032 near the core wire puller 035.

[0035] The first core wire 036 is pulled by the core wire puller 035, which in turn pulls the first stopper 034 to move horizontally. The horizontal movement of the first stopper 034 can open the magnetic path between the drive magnet 02 and the magnet 05. When the core wire puller 035 is not in use, the first stopper 034 can move and reset under the elastic action of the first reset spring 037.

[0036] The stopper is composed of two types of stoppers: a magnetic stopper and an iron stopper. The magnetic force of the basic magnet of this jack and the iron stopper can achieve the purpose of control through the two types of stoppers.

[0037] The following is a brief introduction to the blocking mode's opening and closing: Mode 1: The blocker completely exits the working area between the two magnets, with no obstruction, achieving 100% full opening.

[0038] Mode 2: The blocker completely closes between the two magnets, completely blocking the magnetic pole's action surface and achieving 100% complete closure.

[0039] Mode 3: The blocking part is inserted between the two magnets, blocking 50% of the magnetic pole action surface, and the blocked area and the unblocked area are evenly distributed.

[0040] Mode 4: The blocker opens from 50% to 60% to 70% to 80% to 90% to 100%. The blocker gradually moves out from between the two magnets from a half-blocked state, and the blocking area decreases from 50% to 0%.

[0041] Mode 5: The blocker closes from 50% to 60% to 70% to 80% to 90% to 100%. The blocker gradually inserts between the two magnets from a half-blocking state, and the blocking area continuously increases from 50% to 100%.

[0042] Mode 6: The blocker opens from 1% to 10% to 20% to 30% to 40% to 50%, and gradually exits from between the two magnets as it approaches complete closure, with the blocking area continuously decreasing from 99% to 50%.

[0043] Mode 7: The blocker closes from 1% to 10% to 20% to 30% to 40% to 50%, and the blocker gradually inserts between the two magnets from almost fully open, with the blocking area continuously increasing from 1% to 50%.

[0044] Mode 8: The blocker is fully closed and enters between the two magnets, completely blocking the magnetic pole action surface to achieve 100% complete closure. The magnetic force of the magnetic blocker and the thickness of the iron blocker can be adjusted up and down.

[0045] The magnetic force changes according to different modes, with two magnets of the same name facing each other as the power source.

[0046] The following details eight functions of variable magnetic force technology that can be generated by iron stoppers: The first function is that the iron stopper completely exits the working area between the two magnets, without any obstruction, achieving 100% full opening. The two magnets are magnetic poles of the same name, naturally repelling each other. When there is no obstruction, the repulsive force reaches its maximum value, presenting a state of strong mutual repulsive magnetic force.

[0047] The second function: The iron blocker completely closes between the two magnets, completely blocking the magnetic pole action surface and achieving 100% complete closure. The iron blocker transforms the repulsive force between the two magnets into the attractive force between the two magnets on the iron. The original mutual repulsion is transformed into a strong mutual attraction, and the attractive force reaches its maximum value.

[0048] The third function: The iron blocking part is inserted between the two magnets, blocking 50% of the magnetic pole action surface. The blocked area and the unblocked area are evenly distributed. The unblocked area maintains the repulsive force of the same magnetic pole of the magnet, while the blocked area generates the attractive force of the magnet on the iron. The two are equal in size and opposite in direction, and the repulsive force and attractive force are balanced, so the two magnets do not interact.

[0049] The fourth function: The iron blocker opens from 50% to 60% to 70% to 80% to 90% to 100%. The iron blocker gradually moves out from between the two magnets from a half-blocked state. The blocking area continuously decreases from 50% to 0%. As the blocking area decreases, the attraction of the magnet to the iron gradually weakens, and the repulsive force of the like magnetic poles gradually becomes dominant, eventually reaching the maximum repulsive force. Overall, it presents a continuous change in which the mutual repulsive force gradually increases.

[0050] The fifth function: The iron blocker is closed from 50% to 100%. The iron blocker is gradually inserted between the two magnets from a half-blocking state. The blocking area continuously increases from 50% to 100%. As the blocking area increases, the attraction of the magnet to the iron gradually increases, and the repulsion of the like magnetic poles is gradually canceled out, eventually reaching the maximum attraction. The whole shows a continuous change in the mutual attraction gradually increasing.

[0051] The sixth function: The iron blocker opens from 1% to 10% to 20% to 30% to 40% to 50%. The iron blocker gradually moves out from between the two magnets from near complete closure. The blocking area continuously decreases from 99% to 50%. In the initial state, the attraction is dominant. As the blocking area decreases, the attraction gradually weakens and the repulsion gradually strengthens. Finally, when it is 50% open, it reaches a force balance. The overall result is a continuous change in which the mutual attraction gradually decreases.

[0052] The seventh function: The iron blocker closes from 1% to 10% to 20% to 30% to 40% to 50%. The iron blocker is gradually inserted between the two magnets from almost fully open. The blocking area continuously increases from 1% to 50%. In the initial state, the repulsive force is dominant, approaching the maximum repulsive force. As the blocking area increases, the repulsive force gradually weakens and the attractive force gradually strengthens. Finally, when it is closed at 50%, a force balance is reached. The overall result is a continuous change in which the mutual repulsive force gradually decreases.

[0053] The eighth function: The iron blocker completely closes between the two magnets, completely blocking the magnetic pole action surface and achieving 100% complete closure. When the iron blocker is thinner than the specified size, it cannot completely counteract the repulsive force between the two magnets. Some of the repulsive force will penetrate the blocker and act on the two magnets, forming an uncounted residual repulsive force. Its magnitude is directly related to the extent of insufficient thickness. If the amount of iron-based material used in the iron blocker is reduced, the effective adsorption area or adsorption strength of the two magnets will decrease, and it will not be able to generate enough adsorption force to completely replace the repulsive force. The thickness of the iron blocker can be gradually reduced to adjust its thickness. By closing the iron blocker 100%, the mutual repulsive force between the two magnets can be increased, reduced, or eliminated.

[0054] The thickness of the iron stopper is directly proportional to the repulsive force between the two magnets in the unobstructed state.

[0055] Specifically, the thickness of the iron stopper refers to the effective working thickness of the iron stopper (unit: millimeters), which needs to cover the magnetic pole action surface of the two magnets. The material is a high-permeability iron-based material, which is a key structural dimension for achieving magnetic force control.

[0056] Repulsive force: refers to the natural magnetic repulsion force (unit: Newton) between two magnets (with the same magnetic poles facing each other) when there is no obstruction. It is determined by the magnetic strength of the magnet itself, the area of ​​the magnetic poles, etc., and is the initial power source.

[0057] When the blocker is made of pure iron, its thickness is made of 0.013 mm, 0.13 mm, 1.3 mm, 13 mm and 39 mm respectively, depending on the repulsive force between the two magnets. When the blocker is made of low-purity iron, its thickness is thicker than the above standards.

[0058] When the repulsive force between the two magnets reaches 1 Newton, or 100 grams of pressure, the thickness of the iron stopper is 0.013 millimeters. When the repulsive force between the two magnets reaches 10 Newtons, or 1 kilogram of pressure, the thickness of the iron stopper is 0.13 millimeters. When the repulsive force between the two magnets reaches 100 Newtons, or 10 kilograms of pressure, the thickness of the iron stopper is 1.3 millimeters. When the repulsive force between two magnets reaches 1000 Newtons, or 100 kilograms of pressure, the thickness of the iron stopper will be 13 millimeters. When the repulsive force between the two magnets reaches 3000 Newtons, or 300 kilograms of pressure, the thickness of the iron stopper is 39 millimeters. When the thickness of the iron stopper is manufactured according to the standards specified above, the first seven functions of variable magnetic force technology can be realized.

[0059] When the thickness of the iron blocker is set to be less than the standard thickness, when the iron blocker is driven to the maximum magnetic shielding state, there is still a repulsive force between the two magnets. At this time, the eighth function of variable magnetic force technology can be realized.

[0060] Specifically, the core function of the iron blocker is to convert the repulsive force between two magnets into the attractive force of the magnet on the iron. The key is to completely block the magnetic pole action area with its own thickness, allowing the ferromagnetic material to fully adsorb the two magnets and cancel out the repulsive force. The greater the repulsive force, the higher the interaction strength of the magnetic poles of the two magnets. A thicker ferromagnetic material is needed to completely cover the magnetic pole action area, forming a sufficient adsorption area and adsorption force to completely replace the repulsive force.

[0061] When the iron stopper is made slightly thicker than the specified size, it has little impact on the variable magnetic force technology. However, when the iron stopper is made slightly thinner than the specified size, even when the iron stopper is 100% closed, the mutual repulsion between the two magnets cannot be completely eliminated. The mutual repulsion between the two magnets is clearly visible through the iron stopper. By gradually thinning the iron stopper beyond the specified size and keeping it 100% closed, the repulsion between the two repulsive magnets can be increased, decreased, or eliminated.

[0062] For example, when the repulsive force between two magnets reaches a pressure of 100 kg, a 13 mm thick iron barrier, when 100% closed, can control the repulsive force, causing the two magnets to attract each other very strongly. If the repulsive force reaches 100 kg, a 6.5 mm thick iron barrier, when 100% closed, will significantly reduce the repulsive force to 50 kg. When the iron barrier is slightly thinner than specified, the repulsive force can be clearly seen through it. Even when 100% closed, the iron barrier cannot completely eliminate the repulsive force between the two magnets when it is slightly thinner than specified. In other words, by gradually adjusting the thickness of the iron blocker to be slightly thinner than the specified size, the mutual repulsion force between the two magnets can be reduced to 1 kg or less, or even eliminated. This technology allows for arbitrary adjustment of the mutual repulsion force between the two magnets. This variable magnetic force technology is not limited by the use of double-door or single-door iron blocks. The iron blocker is made of high-purity iron.

[0063] like Figure 5 As shown, the magnetic blocking device is a combination of an iron block 0341 and auxiliary magnets 0342 and 0343 attached to both sides of the iron block 0341. The auxiliary magnets 0342 and 0343 have the same magnetic poles as the two magnets respectively.

[0064] Specifically, the magnetic strength of auxiliary magnets 0342 and 0343 is lower than that of the first driving magnet 02 and magnet 1 05, the second driving magnet 06 and magnet 2 09, and the third driving magnet 15 and magnet 3 16.

[0065] The following details eight functions of variable magnetic force technology that can be generated by magnetic stop devices: The first function is that the magnetic stopper completely exits the working area between the two magnets, without any obstruction, achieving 100% full opening. The two magnets are magnetic poles of the same name, naturally repelling each other. When there is no obstruction, the repulsive force reaches its maximum value, exhibiting a strong mutual repulsion state.

[0066] The second function is that the magnetic blocking device completely closes between the two magnets, completely blocking the magnetic pole action surface and achieving 100% complete closure. The auxiliary magnets 0342 and 0343 minimize the repulsive force between the two magnets through low magnetic repulsion. The mutual repulsive force between the two magnets is reduced to an extremely low level, with no attractive force generated and only a weak repulsive force remaining.

[0067] The third function: The magnetic blocking part is inserted between the two magnets, blocking 50% of the magnetic pole action surface. The blocked area and the unblocked area are evenly distributed. The unblocked area is a strong repulsion between the two magnets, while the blocked area is a low magnetic repulsion. After the two are superimposed, the mutual repulsion force is significantly reduced, resulting in an unbalanced state, but there is still a weak repulsion force.

[0068] The fourth function: The magnetic blocking device opens from 50% to 100%, gradually withdrawing from the two magnets from a semi-blocked state. The blocking area continuously decreases from 50% to 0%. The interaction between the auxiliary magnets 0342 and 0343 and the two magnets gradually weakens and eventually completely separates. The effect of low magnetic repulsion gradually disappears, and the natural repulsion of the two magnets gradually increases, eventually reaching the maximum repulsion force, showing a continuous change in the mutual repulsion force gradually increasing.

[0069] The fifth function: The magnetic blocking device is closed from 50% to 100% and gradually inserted between the two magnets from a semi-blocking state. The blocking area continuously increases from 50% to 100%. The correspondence between the auxiliary magnets 0342 and 0343 and the two magnets is gradually improved. The low magnetic repulsion effect is gradually enhanced, and the influence of the low magnetic repulsion is gradually strengthened. The natural repulsion force of the two magnets is gradually canceled out.

[0070] The sixth function: The magnetic blocking device opens from 1% to 10% to 20% to 30% to 40% to 50%. The magnetic blocking device gradually withdraws from between the two magnets from being almost completely closed. The blocking area continuously decreases from 99% to 50%. The low magnetic repulsion gradually disappears from its strongest point. Initially, it is an extremely low repulsion force. As the blocking area decreases, the repulsion force gradually increases, showing a continuous change throughout the process where the mutual repulsion force gradually increases.

[0071] The seventh function: The magnetic blocking device is closed from 1% to 10% to 20% to 30% to 40% to 50%. The magnetic blocking device is gradually inserted between the two magnets from almost fully open. The blocking area continuously increases from 1% to 50%. The low magnetic repulsion gradually increases from none to the strongest. Initially, it is the maximum repulsion force. As the blocking area increases, the repulsion force gradually decreases to an extremely low level, showing a continuous change throughout the process where the mutual repulsion force gradually decreases.

[0072] The eighth function: The magnetic blocking device is fully closed and enters between the two magnets, completely blocking the magnetic pole action surface and achieving 100% complete closure. When the magnetic force of the auxiliary magnets 0342 and 0343 is adjusted up and down, the mutual repulsion force of the two mutually repelling magnets will gradually decrease and gradually increase.

[0073] Specifically, the auxiliary magnet 0342 is fixed to the bottom of the iron block 0341, and it is connected to the first driving magnet 02, the second driving magnet 06, and the third driving magnet 15. The auxiliary magnet 0342 repels the first driving magnet 02, the second driving magnet 06, and the third driving magnet 15, minimizing their repulsive force and thus achieving a control function. By attaching a low-repulsive auxiliary magnet 0342 to the bottom of the iron block 0341, the repulsive force between the first driving magnet 02, the second driving magnet 06, the third driving magnet 15, and the auxiliary magnet 0342 is minimized, achieving the control purpose. The magnetic force of the auxiliary magnet 0342 attached to the bottom of the iron block 0341 is less than 1 Newton, its thickness is approximately 1 millimeter, and the opposite magnetic poles of the auxiliary magnet 0342, the first driving magnet 02, the second driving magnet 06, and the third driving magnet 15 are the same N pole. When two magnets of the same polarity, 0342 and 0343, are bonded together to form a purely magnetic barrier, the two magnets repel each other. The performance of this purely magnetic barrier is slightly lower than that of a magnetic iron barrier. Therefore, by adding an iron block 0341 between the two magnets to form a magnetic barrier, the magnets 0342 and 0343 will not repel each other, and a magnetic barrier with better control over the magnetic force can be created.

[0074] A secondary magnet 0343 is fixed to the top of iron block 0341 and is connected to magnets 1 (05), 2 (09), and 3 (16) for operation. The secondary magnet 0343 minimizes the repulsive force between magnets 1 (05), 2 (09), and 3 (16) by repelling them, thus achieving a control function. By attaching a low-repulsive secondary magnet 0343 to the top of iron block 0341, the mutual repulsion between magnets 1 (05), 2 (09), 3 (16), and the secondary magnet 0343 is minimized, achieving the control purpose. The magnetic force of the secondary magnet 0343 attached to iron block 0341 is equal to or less than 1 Newton, its thickness is approximately 1 mm, and the opposite magnetic poles of the secondary magnet 0343 and magnets 1 (05), 2 (09), and 3 (16) are all the same N pole.

[0075] Furthermore, the auxiliary magnets 0342 and 0343 used in the magnetic stopper are 1 mm thick, and their magnetic force can be made from 1 Newton to 0.1 Newtons. The lower the magnetic force of the auxiliary magnets 0342 and 0343, the better the repulsive force between the two basic magnets can be controlled. The thickness of the iron block 0341 can be the same as the thickness of the iron stopper, or it can be made thinner. Because the iron block 0341 has magnets attached to both sides, making the iron block 0341 slightly thinner than the above standards can also control the repulsive force between the two repelling magnets. For example: when the repulsive force between two magnets reaches 1 kg of pressure, the thickness of iron block 0341 should be 0.13 mm; when the repulsive force reaches 10 kg of pressure, the thickness should be 1.3 mm; when the repulsive force reaches 100 kg of pressure, the thickness should be 13 mm; and when the repulsive force reaches 300 kg of pressure, the thickness should be 39 mm. Slightly thinner than these standards is also acceptable.

[0076] The range of repulsive force between the two base magnets can be adjusted by regulating the overall magnetization of the magnetic stopper.

[0077] Specifically, the magnetic force of the two base magnets is extremely strong. If the magnetic force of the auxiliary magnet is too high, it will strongly repel the main magnet, causing the magnetic stopper to get stuck between the two magnets. The low magnetic force setting allows the magnetic stopper to be subjected to only a weak repulsive force, so that it slides without jamming and is suitable for the need for continuous reciprocating movement. The repulsive force of the main magnet is the power source.

[0078] By changing the magnetization-related parameters of the components, the magnetization intensity of the two auxiliary magnets can be increased or decreased, thereby directly altering the fundamental magnetization contribution of the magnetic stopper.

[0079] The magnetic strength of auxiliary magnets 0342 and 0343 is lower than that of the two base magnets.

[0080] Furthermore, iron or magnetic stoppers can be selected according to needs to meet the power output requirements in different scenarios. It has strong compatibility, effectively expands the application range, has high energy efficiency, and achieves high-precision adjustment.

[0081] The magnetic force of the jack's base magnet is controlled by an iron stopper and a magnetic stopper, which enables the jack to work normally.

[0082] This jack can be made in various sizes and models within its applicable range.

[0083] This jack is not limited in the use of one, two, or more lifting housings and can be manufactured in various ways as needed.

[0084] When manufacturing these small jacks, the jacks do not require the push frame 13 and the casters 12. However, when manufacturing large jacks, the jacks require the push frame 13 and the casters 12.

[0085] This variable magnetic force technology is not limited by the use of dual-door or single-door magnetic stoppers. This magnetic stopper uses a newly emerging type of magnet.

[0086] The second shielding mechanism 07 also includes a second fixed shaft 072, a second sliding block 073, a core wire puller 035, and a second return spring 077.

By pulling the second core wire 076 through the core wire puller 035, the second stopper 074 can slide on the second fixed shaft 072. The second return spring 077 is sleeved on the second fixed shaft 072 near the core wire puller 035.

[0087] The second core wire 076 is pulled by the core wire puller 035, which in turn pulls the second stopper 074 to move horizontally. The horizontal movement of the second stopper 074 can open the magnetic path between the second drive magnet 06 and the second magnet 09. When the core wire puller 035 is not in use, the second stopper 074 can move and reset under the elastic action of the second reset spring 077.

[0088] The structure and function of the second blocker 074 are the same as those of the first blocker 034, and will not be described in detail here.

[0091] The upper lifting housing 082 rises, which can drive the connecting rod 102 to rise. The rise of the connecting rod 102 can push the push plate 101 to lift the heavy object.

[0092] The connecting rod 102 is fixed in the nut of the lifting housing 082. The height of the jack can be adjusted by rotating the connecting rod 102.
