Description

Technical Field

[0001] The present invention relates to the technical field of household lifting equipment, and more specifically to a multi-purpose hanging pneumatic lifting mechanism and a lifting product thereof. Background Art

[0002] Pneumatic lifting mechanisms are widely used in household items. Their main function is to move the load in a straight line through their own expansion and contraction. As people's requirements for quality of life increase, home furnishings with lifting functions will develop by leaps and bounds.

[0003] The pneumatic lifting mechanism currently on the market generally uses an inner and outer sleeve and a gas spring to achieve lifting. However, there are some defects in the pneumatic lifting mechanism on the market: first, the structure is relatively complex, it is not convenient to assemble, and once damaged, it is also very troublesome to repair; second, due to the limitation of the gas spring stroke, the entire lifting distance is relatively small, and this structure is not applicable to household products that require a larger lifting distance; third, due to the limitation of the existing pneumatic lifting mechanism structure, its application range is very small, generally used for lifting tables and lifting chairs, not applicable to some suspended household products, and not applicable to some household products with slightly larger sizes. If multiple pneumatic lifting mechanisms are set as support, it is possible that the lifting cannot be completed stably due to asynchronous lifting. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a multi-purpose hanging pneumatic lifting mechanism with simple structure, convenient assembly and synchronous lifting at both ends. The pneumatic lifting mechanism can be applied to a variety of lifting products, and the lifting stroke is enlarged.

[0005] According to one aspect of the present invention, a multi-purpose hanging pneumatic lifting mechanism is provided, which includes a support tube, a lockable gas spring, a left steel wire rope, a right steel wire rope, a left roller pin shaft and a right roller pin shaft, the lockable gas spring is accommodated in the support tube, the left roller pin shaft and the right roller pin shaft are respectively arranged at the left and right ends of the support tube, the cylinder end of the lockable gas spring is provided with a left gas spring pin shaft, the piston rod end of the lockable gas spring is provided with a gas spring switch, the gas spring switch is connected to a switch handle through a switch control line, and the gas spring switch is installed with a right gas spring pin shaft, The right pin shaft of the gas spring is provided with a first roller and a second roller, the left pin shaft of the roller is provided with a third roller and a fourth roller, and the right pin shaft of the roller is provided with a fifth roller. The starting ends of the left steel wire rope and the right steel wire rope are connected to the left pin shaft of the gas spring. The left steel wire rope extends to the first roller and bypasses the first roller, and then extends to the third roller, bypasses the third roller, and passes upward through the support tube. The right steel wire rope extends to the second roller and bypasses the second roller, and then extends to the fourth roller and bypasses the fourth roller, and finally extends to the fifth roller, bypasses the fifth roller, and passes upward through the support tube. Therefore, when the support tube needs to be lowered, the switch handle is pulled to turn on the gas spring switch, and the support tube is pulled downward by hand, the piston rod of the lockable gas spring contracts, and the right pin shaft of the gas spring moves leftward, driving the first roller and the second roller to move leftward, the left steel wire rope and the right steel wire rope are shortened in the horizontal direction and lengthened in the vertical direction, and the support tube moves downward. When the support tube descends to the required position, the switch handle is released and the lockable gas spring is locked; when the switch handle is pulled again to turn on the gas spring switch, the piston rod of the lockable gas spring automatically extends outward, the left steel wire rope and the right steel wire rope are lengthened in the horizontal direction and shortened in the vertical direction. The support tube automatically moves upward, and after releasing the switch handle, the support tube can be locked in the desired position; since the left and right steel ropes have a folding design when passing around the first and second rollers, when the lockable gas spring piston rod is extended or contracted to a certain length, the moving distance of the left and right steel ropes in the horizontal direction is twice the length of the extended or contracted length of the piston rod. At the same time, the moving distance of the left and right steel ropes in the vertical direction is also twice the length of the extended or contracted length of the piston rod. Therefore, the multi-purpose hanging pneumatic lifting mechanism has the function of amplifying the lifting stroke, and the assembly structure of each component is convenient. The left and right steel ropes are synchronously controlled by a lockable gas spring to ensure the stability of the lifting of the support frame.

[0006] In some embodiments, the left steel wire rope and the first roller are located on a side close to the lockable gas spring, and a limit plate is provided outside the first roller and the second roller, and the limit plate is installed on the right pin of the gas spring, and the left pin of the roller, the right pin of the roller and the left pin of the gas spring are all provided with a limit short tube. Thus, the limit plate can prevent the left and right steel wire ropes from escaping from the annular grooves of the first and second rollers, and the limit short tube can prevent the third, fourth and fifth rollers from moving, and the position of the starting ends of the left and right steel wire ropes can also be limited to prevent movement.

[0007] According to another aspect of the present invention, lifting products based on the multi-purpose hanging pneumatic lifting mechanism are provided, and these lifting products include lifting clothes hangers, lifting clothes drying racks, lifting tables, and lifting cabinets. Therefore, the multi-purpose hanging pneumatic lifting mechanism has a very wide application range. In practical applications, some objects can be installed on the support tube of the multi-purpose hanging pneumatic lifting mechanism to achieve the lifting of objects; the support tube of the multi-purpose hanging pneumatic lifting mechanism can also be fixed to the top plate of an object, and another object can be installed on two left and right steel wire ropes extending downward, and the switch handle can be installed on the object, which can also achieve the lifting of objects; the multi-purpose hanging pneumatic lifting mechanism is suitable for objects that need to move up and down, can be installed in a hanging manner, and has the advantages of saving space, convenient to take, and easy to operate.

Therefore, the wardrobes used by families nowadays are generally high, and the space above the wardrobe is often idle because it is inconvenient to store and access items, resulting in waste. The lifting clothes hanger makes full use of the upper space of the wardrobe to bring convenience to life. The entire lifting clothes hanger is hung on the inner top plate of the wardrobe through the hanging ears, and the hook holes can be used to hang the hanger. The clothes hanging board and the support tube are synchronously lifted and lowered as a whole.

[0009] In some embodiments, the clothes hanging board is connected to two switch ropes, a crossbar is connected between the ends of the two switch ropes, a baffle is provided above the crossbar, a sleeve is provided on the switch rope between the baffle and the crossbar, a switch handle is located between the baffle and the crossbar, and a switch control line passes through the baffle and is connected to the switch handle. Thus, when it is necessary to hang or remove clothes, the switch handle is pulled downward, the lockable gas spring is opened, the piston rod of the lockable gas spring is contracted, the steel wire rope in the vertical direction is extended, and the clothes hanging board moves down to a convenient position for hanging and taking. After hanging or taking clothes, the switch handle is pulled again, and the support pipe, the clothes hanging board and the clothes automatically rise together, which is very convenient and light, avoiding the trouble of using a table or a stool to store and take clothes, and reducing safety hazards.

[0010] In some embodiments, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting clothes drying rack, the lifting clothes drying rack comprises a left transverse connecting plate, a right transverse connecting plate and a clothes drying rod, the left transverse connecting plate and the right transverse connecting plate are respectively connected to the two ends of the support tube, the clothes drying rod is provided with two, the two ends of the clothes drying rod are respectively connected to the left transverse connecting plate and the right transverse connecting plate, the clothes drying rod is provided with a plurality of hook holes, and the ends of the left steel wire rope and the right steel wire rope are both connected with a mounting cover plate. Therefore, the lifting clothes drying racks currently used are mostly hand-cranked clothes drying racks and electric clothes drying racks, the former are complicated to install, easy to get stuck, and the lifting speed of the handle is slow, and the latter has more functions, but a complex structure and a high price, while the lifting clothes drying rack has fewer parts, a compact appearance, and is easy to install, and only needs to fix the mounting cover plate on the ceiling, the lifting clothes drying rack does not require power, which improves the safety during use, the hook hole can be used for hanging clothes on the clothes hanger, and the clothes drying rod rises and falls synchronously with the support tube.

[0011] In some embodiments, the two ends of the clothes drying rod are connected to the quilt drying rod through the rod end connecting plates, the left transverse connecting plate and the right transverse connecting plate are both provided with a slot, the rod end connecting plate is provided with a guide hole, and the two ends of the quilt drying rod can be movably installed in the guide hole. Therefore, when the quilt drying rod is not in use, the quilt drying rod can be rotated and stored in the slot, and the guide hole of the rod end connecting plate is to provide a movement space for the quilt drying rod when it is stored.

[0012] In some embodiments, two left and right steel wire ropes are provided, two groups of the first roller, the second roller, the third roller, the fourth roller, and the fifth roller are provided, and are symmetrically arranged relative to the lockable gas spring, the two groups of the first roller and the second roller are installed on the same right pin of the gas spring, the two groups of the third roller and the fourth roller are installed on the same left pin of the roller, and the two groups of the fifth roller are installed on the same right pin of the roller. Therefore, in order to improve the load-bearing capacity and balance of the lifting clothes drying rack, two left and right steel wire ropes are provided and symmetrically located on both sides of the lockable gas spring in the support tube, and the same lockable gas spring synchronously controls the four steel wire ropes.

[0013] In some embodiments, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting table, which includes a desktop panel, a back panel and a linear optical axis. The two ends of the support tube are connected to a desktop support plate, the desktop panel is installed above the desktop support plate, the two ends of the linear optical axis are mounted on one side of the back panel through an optical axis mounting plate, the desktop support plate is slidably connected to the linear optical axis through a slider bearing, and the ends of the left wire rope and the right wire rope pass through the desktop and are connected to the optical axis mounting plate. Therefore, with the demand for healthy life and efficient work, more and more people choose to study and work in a sit-stand alternating manner, and various lifting tables and lifting platforms have emerged. In combination with the multi-purpose hanging pneumatic lifting mechanism, a wall-mounted lifting table can be formed. The lifting table has a simple structure and fewer parts. When the desktop panel needs to be raised, the switch handle is pressed, the gas spring switch is turned on, the piston rod of the lockable gas spring is automatically extended, the left and right wire ropes in the vertical direction are shortened, and the desktop panel moves upward relying on the guiding action of the slider bearing and the linear optical axis. When the desktop rises to an appropriate height, the switch handle is released, the gas spring switch is closed and locked, and the desktop can bear It will not drop even under a pressure of more than 100kg. When the desktop needs to drop, press the switch handle again, then press down the desktop, the piston rod of the lockable gas spring contracts, the left and right steel wire ropes in the vertical direction extend, the desktop drops, and when it drops to a suitable height, release the switch handle to lock the desktop. The lifting table can reduce deformation during use, extend its service life, and make the lifting operation smoother and more comfortable. The lifting table can lower the desktop to a position very low from the ground, but because the multi-purpose hanging pneumatic lifting mechanism has a stroke amplification effect and a large stroke, the desktop can still be raised to a higher position, which is suitable for more people.

[0014] In some embodiments, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting cabinet machine, which includes a cabinet body and a shelf. The two sides of the shelf are movably connected to the cabinet body through slide rails, and the support pipe is installed at the bottom of the shelf. The ends of the left and right steel wire ropes are connected to the cabinet body through the installation of hanging plates. The shelf is provided with a support plate, and the support plate is connected to a guardrail. Therefore, the cabinet machines on the market are now dominated by electric lifting, which has a complex structure and high cost. The lifting cabinet machine realizes lifting and locking through a hanging pneumatic lifting mechanism to reduce manufacturing costs and bring convenience to more families; slide rails are installed on both sides of the shelf to realize the lifting and guiding function of the shelf, and a guardrail is installed on the support plate to place different kitchen utensils and seasonings.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-purpose hanging pneumatic lifting mechanism provided by the present invention has a simple structure and a compact layout. The extension and contraction of the lockable gas spring piston rod is used to drive the roller on the piston rod to move, and the lifting function of the mechanism is realized by the movement of the left and right steel wire ropes wound around the rollers. Since the left and right steel wire ropes have a folding design when passing around the first and second rollers, when the lockable gas spring piston rod is extended or contracted to a certain length, the moving distance of the left and right steel wire ropes in the vertical direction is twice the extension or contraction length of the piston rod, which has the effect of amplifying the lifting stroke. The hanging pneumatic lifting mechanism can be applied to a variety of lifting products and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described below in conjunction with specific implementation modes.

[0034] Example 1

[0035] like Figures 1 to 5As shown, a multi-purpose hanging pneumatic lifting mechanism according to an embodiment of the present invention comprises a support tube 1, a lockable gas spring 2, a left steel wire rope 31, a right steel wire rope 32, a left roller pin 41 and a right roller pin 42. The left roller pin 41 and the right roller pin 42 are fixedly mounted on the left and right ends of the support tube 1, respectively, and the lockable gas spring 2 is accommodated in the support tube 1 and fixed by a fixing plate 11. The cylinder end of the lockable gas spring 2 is fixedly connected with a left gas spring pin 43, and the piston rod end of the lockable gas spring 2 is installed with a gas spring switch 21. The gas spring switch 21 is connected with a switch control line 22, and the end of the switch control line 22 is connected with a switch handle 20. The gas spring switch 21 is fixedly mounted with a right gas spring pin 44, and a first roller 51 and a second roller 52 are mounted on the right gas spring pin 44. The left roller pin 41 is installed with a third roller 53 and a fourth roller 54, and the right roller pin 42 is installed with a fifth roller 55. The starting ends of the left steel wire rope 31 and the right steel wire rope 32 are both connected to the gas spring left pin 43. The left steel wire rope 31 and the first roller 51 are located on the side close to the lockable gas spring 2. The left steel wire rope 31 extends to the right end to the top of the first roller 51, bypasses the first roller 51, then turns back to the left end from the bottom of the first roller 51, extends to the bottom of the third roller 53, bypasses, and passes upward through the support tube 1 from the left side of the third roller 53. The right steel wire rope 32 extends to the right end to the top of the second roller 52, bypasses the second roller 52, then turns back to the left end from the bottom of the second roller 52, extends to the top of the fourth roller 54, bypasses the fourth roller 54, and finally turns back from the bottom of the fourth roller 54 to the right end to extend to the fifth roller 55, bypasses the bottom of the fifth roller 55, and passes upward through the support tube 1 from the right side of the fifth roller 55.

[0036] A limit plate 56 is provided above the first roller 51 and the second roller 52. The limit plate 56 is U-shaped, and both ends of the limit plate 56 are mounted on the right pin shaft 44 of the gas spring. The limit plate 56 can prevent the left and right steel wire ropes (31, 32) from escaping from the annular grooves of the first and second rollers (51, 52). The left roller pin shaft 41, the right roller pin shaft 42 and the left gas spring pin shaft 43 are all provided with a limit short tube 45. The limit short tube 45 can prevent the third, fourth and fifth rollers (53, 54, 55) from moving, and can also limit the position of the starting ends of the left and right steel wire ropes (31, 32) to prevent moving.

[0037] The working process of this embodiment 1:

[0038] like Figure 2 and 5As shown, when the support tube 1 needs to be lowered, the switch handle 20 is pulled to turn on the gas spring switch 21, and the support tube 1 is pulled downward by hand, the piston rod of the lockable gas spring 2 is contracted, and the right pin shaft 44 of the gas spring moves to the left, driving the first roller 51 and the second roller 52 to move to the left, the length of the left steel wire rope 31 and the right steel wire rope 32 in the horizontal direction is shortened, and the length in the vertical direction is extended, and the support tube 1 moves downward. When the support tube 1 descends to the desired position, the switch handle 20 is released, and the lockable gas spring 2 is locked. When the switch handle 20 is pulled again to turn on the gas spring switch 21, the piston rod of the lockable gas spring 2 automatically extends outward, the length of the left steel wire rope 31 and the right steel wire rope 32 in the horizontal direction is extended, and the length in the vertical direction is shortened, and the support tube 1 automatically moves upward. After releasing the switch handle 20, the support tube 1 can be locked at the desired position.

[0039] Since the left and right steel wire ropes (31, 32) have a folding design when passing around the first and second rollers (51, 52), when the piston rod of the lockable gas spring 2 is extended or contracted to a certain length, the moving distance of the left and right steel wire ropes (31, 32) in the horizontal direction is twice the length of the extended or contracted piston rod, and at the same time, the moving distance of the left and right steel wire ropes (31, 32) in the vertical direction is also twice the length of the extended or contracted piston rod. Therefore, the multi-purpose hanging type pneumatic lifting mechanism has the function of amplifying the lifting stroke, and the assembly structure of each component is convenient, and the left and right steel wire ropes (31, 32) are synchronously controlled by a lockable gas spring 2 to ensure the stability of the lifting of the support frame.

[0040] The multi-purpose hanging pneumatic lifting mechanism is suitable for objects that need to move up and down, and has a very wide range of applications. Therefore, the present invention also provides some lifting products based on the multi-purpose hanging pneumatic lifting mechanism, and these lifting products include lifting clothes hangers, lifting clothes drying racks, lifting tables, lifting cabinets, lifting beds, commercial display cabinets, etc. In practical applications, some objects can be installed on the support pipe 1 of the multi-purpose hanging pneumatic lifting mechanism, and the lifting of objects can be realized. In addition, the multi-purpose hanging pneumatic lifting mechanism can also be installed upside down, the support pipe 1 of the multi-purpose hanging pneumatic lifting mechanism is fixed on the top plate of an object, and the other object is installed on two left and right steel wire ropes (31, 32) extending downward, and the switch handle 20 is installed on the object below, and the lifting function of the object can also be realized. The multi-purpose hanging pneumatic lifting mechanism is applied to homes or other fields, and can realize the hanging installation and lifting of objects, and has the advantages of saving space, convenient picking, and easy operation.

[0041] Example 2

[0042] like Figures 6 to 8As shown, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting clothes hanger, which includes a clothes hanging board 61 and a wardrobe 6. The clothes hanging board 61 is fixedly connected to the bottom of the support tube 1, and the clothes hanging board 61 is provided with a plurality of evenly arranged hook holes 611. The clothes hanging board 61 and the support tube 1 can be made into one piece with aluminum alloy material through an extrusion process. The ends of the left steel wire rope 31 and the right steel wire rope 32 are both connected with a lifting ear 62, and the lifting ear 62 is installed on the inner top plate of the wardrobe 6. The wardrobe 6 used in families is generally high now, and the space above the wardrobe 6 is often idle because it is inconvenient to store and access items, resulting in waste. The lifting clothes hanger makes full use of the upper space of the wardrobe 6 to bring convenience to life. The entire lifting clothes hanger is hung on the inner top plate of the wardrobe 6 through the lifting ear 62, and the hook hole 611 can be used to hang the hanger. The clothes hanging board 61 and the support tube 1 are lifted and lowered synchronously.

[0043] Two switch hanging ropes 201 are connected to the middle position of the clothes hanging board 61, and a cross bar 202 is connected between the ends of the two switch hanging ropes 201. A baffle 203 is provided above the cross bar 202, and a sleeve 204 is sleeved on the switch hanging rope 201 between the baffle 203 and the cross bar 202. The switch handle 20 is located between the baffle 203 and the cross bar 202, and the switch control line 22 passes through the baffle 203, and the core of the switch control line 22 is connected to the switch handle 20.

[0044] Working process of this embodiment 2: when it is necessary to hang or take off clothes, pull the switch handle 20 downward, the lockable gas spring 2 opens, the piston rod of the lockable gas spring 2 contracts, the right pin shaft 44 of the gas spring moves to the left, driving the first roller 51 and the second roller 52 to move to the left, the length of the left steel wire rope 31 and the right steel wire rope 32 in the horizontal direction shortens, and the length in the vertical direction lengthens, the clothes hanging board 61 moves down to a convenient hanging position, release the switch handle 20, and the lockable gas spring 2 is locked. After hanging or taking off clothes, pull the switch handle 20 again, the piston rod of the lockable gas spring 2 automatically extends outward, the length of the left steel wire rope 31 and the right steel wire rope 32 in the horizontal direction lengthens, and the length in the vertical direction shortens, and the support tube 1 and the clothes hanging board 61 automatically rise together with the clothes. The lifting clothes hanger is very convenient and light, avoiding the trouble of using a table or a stool to store and take clothes, and reducing safety hazards.

[0045] Example 3

[0046] like Figures 9 to 13As shown, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting clothes drying rack, which includes a left transverse connecting plate 71, a right transverse connecting plate 72 and a clothes drying rod 7. The left transverse connecting plate 71 and the right transverse connecting plate 72 are respectively fixedly connected to the two ends of the support tube 1. There are two clothes drying rods 7, and the clothes drying rod 7 is provided with a number of evenly distributed hook holes 701. The two ends of the clothes drying rod 7 are respectively connected to the left transverse connecting plate 71 and the right transverse connecting plate 72. The ends of the left steel wire rope 31 and the right steel wire rope 32 are both connected to the installation cover plate 73. The lifting clothes drying racks currently used are mostly hand-cranked clothes drying racks and electric clothes drying racks. The former is complicated to install, easy to get stuck, and the lifting speed of the handle is slow, while the latter has more functions, but a complex structure and a high price. The lifting clothes drying rack provided by the present invention has fewer parts, a compact appearance, and is easy to install. It only needs to fix the installation cover plate 73 on the ceiling with expansion screws. The lifting clothes drying rack does not require power supply, which improves safety during use. The hook hole 611 can be used for hanging clothes on the clothes hanger, and the clothes drying rod 7 rises and falls synchronously with the support tube 1.

[0047] The two ends of the clothes drying rod 7 are connected to the quilt drying rod 75 through the rod end connecting plate 74. Both the clothes drying rod 7 and the quilt drying rod 75 can be telescopic. The left transverse connecting plate 71 and the right transverse connecting plate 72 are provided with a clamping groove 76. The rod end connecting plate 74 is provided with a guide hole 741. The two ends of the quilt drying rod 75 can be movably installed in the guide hole 741. When the quilt drying rod 75 is not in use, the quilt drying rod 75 can be rotated and stored in the clamping groove 76. The guide hole 741 of the rod end connecting plate 74 is to provide a movement space for the quilt drying rod 75 when it is stored.

[0048] In this embodiment, in order to improve the load-bearing capacity and balance of the lifting clothes drying rack, the left steel wire rope 31 and the right steel wire rope 32 are both provided in two and symmetrically located on both sides of the lockable gas spring 2 in the support tube 1, and the same lockable gas spring 2 synchronously controls the four steel wire ropes. Accordingly, the first roller 51, the second roller 52, the third roller 53, the fourth roller 54 and the fifth roller 55 are each provided in two groups and are symmetrically arranged relative to the lockable gas spring 2. The two groups of the first roller 51 and the second roller 52 are both installed on the same gas spring right pin 44, the two groups of the third roller 53 and the fourth roller 54 are both installed on the same roller left pin 41, and the two groups of the fifth roller 55 are both installed on the same roller right pin 42.

[0049] In this embodiment, the lifting control method of the lifting clothes drying rack is consistent with the lifting control method of the lifting clothes hanging rack in Example 2, and the installation of the switch handle 20 is also the same. The only difference is that the extension and contraction of the lockable gas spring 2 of the lifting clothes drying rack simultaneously controls the synchronous lifting and lowering of the four steel wire ropes.

[0050] Example 4

[0051] like Fig.14 and 15As shown, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting table. The lifting table includes a desktop panel 8, a back panel 81 and a linear optical axis 82. The two ends of the support tube 1 are fixedly connected with a desktop support plate 84, and the desktop support plate 84 is L-shaped. The desktop panel 8 is installed above the desktop support plate 84, and the two ends of the linear optical axis 82 are mounted on one side of the back panel 81 through an optical axis mounting plate 821. The side of the desktop support plate 84 is connected with a slider bearing 83 by screws, and the slider bearing 83 can be slidably connected to the linear optical axis 82. The desktop panel 8 is provided with a small hole (not shown in the figure), and the ends of the left wire rope 31 and the right wire rope 32 pass through the small hole of the desktop panel 8 and are connected to the optical axis mounting plate 821. Switch handle 20 With the demand for healthy life and efficient work, more and more people choose to sit and stand alternate learning and working methods. Various lifting tables and lifting platforms have emerged. Combining the multi-purpose hanging pneumatic lifting mechanism can form a wall-mounted lifting table. The lifting table has a simple structure and fewer parts.

[0052] Working process of this embodiment 4: when the desktop 8 needs to be raised, press the switch handle 20, the gas spring switch 21 opens, the piston rod of the lockable gas spring 2 automatically extends, the length of the left wire rope 31 and the right wire rope 32 in the horizontal direction is extended, and the length in the vertical direction is shortened, and the desktop 8 moves upward by relying on the guiding effect of the slider bearing 83 and the linear optical axis 82. When the desktop rises to an appropriate height, release the switch handle 20, the gas spring switch 21 is closed and locked, and the desktop can withstand a pressure of more than 100kg without falling. When the desktop 8 needs to be lowered, press the switch handle 20 again, and then press the desktop 8 downward, the piston rod of the lockable gas spring 2 shrinks, the left and right wire ropes (31, 32) in the vertical direction are extended, and the desktop 8 descends. When it descends to an appropriate height, release the switch handle 20 and the desktop is locked. The lifting table can reduce deformation during use, extend its service life, and make the lifting operation smoother and more comfortable. The lifting table can lower the desktop to a position very low to the ground. However, since the multi-purpose hanging pneumatic lifting mechanism has a stroke amplification effect and a large stroke, the desktop can still be raised to a higher position, making it suitable for use by more people.

[0053] Example 5

[0054] like Fig.16 and 17As shown, the multi-purpose hanging pneumatic lifting mechanism is applied to a lifting cabinet machine. The lifting cabinet machine includes a cabinet 91 and a shelf 92, both sides of the shelf 92 are movably connected to the cabinet 91 through slide rails 93, a support pipe 1 is fixedly installed at the bottom of the shelf 92, the ends of the left steel wire rope 31 and the right steel wire rope 32 are connected to the top plate of the cabinet 91 by installing a hanging plate 94 and fixing with screws, and the shelf 92 is installed with a multi-layer support plate 921, and the support plate 921 is connected with a guardrail 922. The cabinet machines on the market are now dominated by electric lifting, with complex structures and high costs. The lifting cabinet machine provided by the present invention is lifted and locked by a hanging pneumatic lifting mechanism to reduce manufacturing costs and bring convenience to more families. The lifting control method of the lifting cabinet machine is the same as the lifting control method of the lifting clothes rack in Example 2. In addition, slide rails 93 are installed on both sides of the shelf 92 to realize the lifting and guiding function of the shelf 92. A guardrail 922 is installed on the support plate 921 to place different kitchen utensils and seasonings.

[0055] The multi-purpose hanging pneumatic lifting mechanism provided by the present invention has a simple structure and a compact layout. The extension and contraction of the piston rod of the lockable gas spring 2 is utilized to drive the roller on the piston rod to be displaced, and the left and right steel wire ropes 32 wound around the rollers move to realize the lifting function of the mechanism. Since the left and right steel wire ropes (31, 32) have a folding design when passing around the first and second rollers (51, 52), when the piston rod of the lockable gas spring 2 is extended or contracted to a certain length, the moving distance of the left and right steel wire ropes (31, 32) in the vertical direction is twice the length of the extension or contraction of the piston rod, which has the effect of amplifying the lifting stroke. The hanging pneumatic lifting mechanism can be applied to a variety of lifting products and has a wide range of applications.

[0056] The above are only some partial implementation methods of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the principle and spirit of the present invention and without realizing the creative concept, other modifications, improved products or products with equivalent replacement of some of the technical features therein can be made, which all fall within the scope of protection of the present invention.
