Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0033] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0034] Example 1, with reference to Figures 1 to 8 , which is a first embodiment of the present invention, provides a pneumatic lifting platform, which includes a platform unit 100, including a main platform 101, extension platforms 102 arranged on both sides of the main platform 101, a horizontal control component 103 arranged inside the main platform 101, and a telescopic component 104 arranged on the horizontal control component 103 and connected to the extension platforms 102;

[0035] The airbag 201e lifting unit 200 includes an airbag 201e connecting component 201 arranged on the extension platform 102, a winding component 202 arranged on the main platform 101, an air pipe connecting component 203 arranged on the winding component 202 and connected to the airbag 201e connecting component 201, and a storage and positioning component 204 arranged on the winding component 202 and coordinated with the airbag 201e connecting component 201.

[0036] The main platform 101 is hollow, and the position of the entire extension platform 102 on the main platform 101 can be adjusted by the telescopic assembly 104, thereby adjusting the position of the two sets of airbags 201e connecting the assembly 201, so that the device can be supported and used on steps of different spans, thereby enhancing the applicability of the device;

[0037] During use, the air pipe connecting component 203 is connected to the air compressor, and air is input into the two groups of airbag 201e connecting components 201 using the air compressor and the air pipe connecting component 203, so that the two groups of airbag 201e components are expanded and raised. The horizontal control component 103 can ensure the horizontal stability of the main platform 101 and the extension platform 102 when the airbag 201e connecting component 201 is expanded and raised. When the device is finished using, the storage and positioning component 204 can be used to shrink the airbag 201e connecting component 201 to connect with the winding component 202, thereby reducing the space occupied by the device and facilitating the movement and carrying of the device.

[0038] Example 2, reference Figures 1 to 8 , which is a second embodiment of the present invention, differs from the first embodiment in that: the horizontal control assembly 103 includes a center plate 103a disposed inside the main platform 101, a trigger ball 103b disposed inside the center plate 103a, a sliding cavity 103c disposed inside the center plate 103a and cooperating with the trigger ball 103b, and contact points 103d disposed on both sides of the sliding cavity 103c; wherein, the center plate 103a is fixedly connected to the center position inside the main platform 101, the sliding cavity 103c is opened inside the center plate 103a, the trigger ball 103b is slidably connected to the sliding cavity 103c, the number of contact points 103d is at least four, respectively, two groups on the left and right, disposed on both sides of the sliding cavity 103c, and the trigger ball 103b is configured as a copper ball with conductive properties. When the horizontal control component 103, i.e., the center plate 103a and the main platform 101, tilts slightly, the trigger ball 103b will roll to the end, turning on the contact point 103d, and controlling the solenoid valve 203a-3 in the air pipe connection component 203 to stop supplying compressed air to the group of air bags 201e supported at the high tilt, and continue to supply compressed air to the group of air bags 201e supported at the low tilt until the tilt is eliminated. The trigger ball 103b disengages from the contact point, and the actuated solenoid valve 203a-3 returns to its original position, restoring the compressed air supply to both groups of supporting air bags 201e at the same time, so that the main platform 101 can be lifted up in a horizontal state. Similarly, the horizontal descent of the main platform 101 is also achieved by triggering the trigger ball 103b to control the solenoid valve 203a-3 that controls the compressed air inlet and outlet of the left and right groups of supporting air bags 201e.

[0039] Furthermore, the telescopic assembly 104 includes a U-shaped extension plate 104a arranged inside the main platform 101 and connected to the extension platform 102, and a cylinder 104b arranged on both sides of the median plate 103a and connected to the U-shaped extension plate 104a; wherein, the U-shaped extension plate 104a and the main platform 101 are slidably connected, and the U-shaped extension plate 104a and the extension platform 102 are fixedly connected, and the two cylinders 104b are respectively fixedly connected to the middle of both sides of the median plate 103a, and the opposite ends of the two cylinders 104b are respectively fixedly connected to the two U-shaped extension plates 104a. The positions of the two extension platforms 102 on the main platform 101 can be adjusted by the cylinder 104b, thereby adjusting the spacing between the two groups of airbags 201e, so that the two strings of airbags 201e can be supported and used on steps with different spans, further enhancing the applicability of the device.

[0040] Furthermore, the airbag 201e connecting assembly 201 includes an upper support plate 201a provided on the extension platform 102, and a lower support plate 201b provided below the upper support plate 201a, and a support frame 201c is provided on the opposite side of the upper support plate 201a and the lower support plate 201b, and a rope threading hole 201d is provided on the support frame 201c; wherein, the top of the upper support plate 201a is fixedly connected to the bottom of the extension platform 102, and the support frame 201c is fixedly connected to the upper support plate 201a. , and the lower support plate 201b are fixedly connected, and the support frame 201c is arranged in a criss-cross pattern, and there are multiple rope holes 201d. Through the arrangement of the upper support plate 201a and the lower support plate 201b, the stability of the two groups of airbags 201e can be enhanced. Since the airbag 201e is a soft support, through the arrangement of the lower support plate 201b, the support on the step is a hard support such as the lower support plate 201b, and the airbag 201e support will not be unstable.

[0041] Furthermore, the airbag 201e connecting assembly 201 further includes a plurality of airbags 201e arranged between the upper support plate 201a and the lower support plate 201b, square positioning holes 204d201f arranged on the airbag 201e, and a binding rope 201g arranged on the airbag 201e and connected to the rope hole 201d and the square positioning holes 204d201f, and an airbag 201e joint is provided on the airbag 201e; wherein the number of the square positioning holes 204d201f is set in a plurality, and the support frame 201c is arranged in a crisscross pattern around the plurality of square positioning holes 204d201f, and adjacent two airbags 201 The square positioning holes 204d201f between the two groups of airbags 201e are fixed by multiple binding ropes 201g, and the top and bottom two airbags 201e are fixedly connected to the rope holes 201d on the upper support plate 201a and the lower support plate 201b respectively by multiple binding ropes 201g. Since the airbags 201e and the airbags 201e are connected and fixed by the square positioning holes 204d201f and the binding ropes 201g, when the gas input to the two groups of airbags 201e increases, there will be no skewing, thereby ensuring the supporting strength of the two groups of airbags 201e and the stability of the main platform 101 and the extension platform 102.

[0042] Furthermore, the winding assembly 202 includes a U-shaped fixing plate 202a arranged on the main platform 101, a winding drum 202b arranged on the U-shaped fixing plate 202a, and a main air pipe arranged on the winding drum 202b; wherein, the U-shaped fixing plate 202a is fixedly connected to the middle part of the bottom of the main platform 101, the winding drum 202b is rotatably connected to the middle position of the U-shaped fixing plate 202a through a bearing, and the main air pipe is wound on the winding drum 202b.

[0043] Furthermore, the trachea connection assembly 203 includes two annular trachea 203a provided on the U-shaped fixing plate 202a, a trachea connector 203b provided on the annular trachea 203a, and a gas hose 203c provided on the trachea connector 203b and connected to the airbag 201e connector, and a control valve 203d is provided on the trachea connector 203b; wherein the number of the trachea connector 203b is provided, and is evenly distributed in an annular manner and connected to the annular trachea 203a, and the gas hose 203c is provided on the trachea connector 203b. One end of c is connected to the trachea connector 203b, and the other end of the gas hose 203c is connected to the air bag 201e connector. Since the two groups of air bags 201e can be connected by the binding rope 201g to increase or decrease the number, they are suitable for operations at different heights. Since the number of trachea connectors 203b that need to be connected to different numbers of air bags 201e will also change accordingly, the gas can be controlled to be delivered only to the trachea connector 203b connected to the gas hose 203c through the setting of the control valve 203d.

[0044] Furthermore, a transverse pipe 203a-1 is provided on the annular air pipe 203a, and both transverse pipes 203a-1 are connected to the main air pipe through a gas branch pipe 203a-2. Both gas branch pipes 203a-2 are provided with a solenoid valve 203a-3. The transverse pipe 203a-1 is fixedly connected to the U-shaped fixing plate 202a through a fixing block 203a-4; wherein, the transverse pipe 203a-1 is connected to the annular air pipe 203a, one end of the gas branch pipe 203a-2 is connected to the transverse pipe 203a-1, and the other end is connected to the main pipe, and the two solenoid valves 203a-3 are respectively controlled by the left and right contact points 103d inside the sliding cavity 103c.

[0045] When in use, since the two sets of air bags 201e are in a soft state in the initial state of the device before use, the positions of the two extension platforms 102 and the two sets of air bags 201e are adjusted to fit the span of the step currently in use by controlling the air cylinder 104b, the main air pipe is pulled out of the winding drum 202b to a suitable length, and connected to the air compressor, and the air compressor is started. Because when the device is placed on the steps, the main platform 101 and the extension platform 102 are in an inclined state as a whole due to the different spans and heights of the steps, and when the main platform 101 is in an inclined state, the trigger ball 103b is in the sliding cavity. The interior of 103c is in contact with the contact point 103d at the lower part of the slope, thereby triggering the corresponding solenoid valve 203a-3, so that the air compressor can only provide compressed air to a group of air bags 201e at the lower part of the slope, so that the group of air bags 201e starts to lift. When the trigger ball 103b breaks away from the contact point 103d, it means that the main platform 101 and the extension platform 102 are horizontal. At this time, another solenoid valve 203a-3 opens, and the air compressor starts to synchronously deliver compressed air to the two groups of air bags 201e, so that the two groups of air bags 201e are synchronously lifted until they are lifted to the appropriate height.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the storage positioning component 204 includes two connecting plates 204a arranged on the U-shaped fixing plate 202a, and a threaded rod 204b arranged on the connecting plate 204a; wherein, the connecting plate 204a is fixedly connected to the U-shaped fixing plate 202a, and the threaded rod 204b is threadedly connected to the connecting plate 204a.

[0048] Furthermore, the storage positioning assembly 204 also includes a vertical plate 204c arranged on the lower support plate 201b, and a positioning hole 204d opened on the vertical plate 204c and cooperating with the threaded plate; wherein, the vertical plate 204c is fixedly connected to the top side of the lower support plate 201b close to the main platform 101.

[0049] During use, after the device has been used, all the gas inside the two groups of air bags 201e is extracted through the air compressor, and then the lower support plate 201b is moved upward to squeeze multiple air bags 201e. After the lower support plate 201b moves up to a certain position, the threaded rod 204b is rotated to make it enter the positioning hole 204d to complete the storage of the device.

[0050] The remaining structures are the same as those of Example 2.
