[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1 Reference Figure 1 to Figure 11 , which is the first embodiment of the present invention, and this embodiment provides an adjustable assembled mobile lifting work platform. The adjustable assembled mobile lifting work platform includes a limit assembly 200, a lifting assembly 300 and a main assembly 100. The cooperation of the three can ensure the safety of the platform during lifting and use.

[0032] The limiting assembly 200 includes a limiting member 201, including a limiting pin 201a, an anti-falling pin 201b, a movable plate 201c, a protrusion 201d, an extrusion rod 201e, a movable bar 201f and a movable plate 201g. The anti-falling pin 201b is arranged below the limiting pin 201a, the movable plate 201c is sleeved on the outside of the anti-falling pin 201b, the movable plate 201c and the anti-falling pin 201b are movably connected, the limiting pin 201a is hinged to the top of the movable plate 201c, the protrusion 201d is fixed on one side of the movable plate 201c, the extrusion rod 201e is arranged on one side of the protrusion 201d, the movable bar 201f is fixed on one side of the movable plate 201c, the movable plate 201g is sleeved on the outside of the movable bar 201f, and the movable plate 201g and the movable bar 201f are movably connected.

[0033] The limiting members 201 are provided in multiple groups, all of which are located on the support frame 101. When the main platform 102 needs to be lifted or lowered, in order to move the main platform 102 to a specified position and prevent the main platform 102 from moving excessively, it needs to be limited. By rotating the squeezing rod 201e, the squeezing rod 201e squeezes the protrusion 201d. Squeezing the protrusion 201d to move it can drive the moving plate 201c to move. The movement of the moving plate 201c will drive the limiting pin 201a and the anti-falling pin 201b to move, so that the two move to one side of the moving block 104. When the main platform 102 moves, the moving block 104 will be driven to move. The movement of the moving block 104 will squeeze the bottom of the anti-fall pin 201b. The bottom of the anti-fall pin 201b is set as an inclined surface. When the bottom of the anti-fall pin 201b is squeezed, the anti-fall pin 201b can be moved into the moving plate 201c. When the moving block 104 moves to separate from the anti-fall pin 201b, the anti-fall pin 201b will return to its original position, thereby supporting the bottom of the moving block 104 to prevent the moving block 104 from falling, thereby preventing the main platform 102 from falling after moving to the specified position.

[0034] A baffle is arranged on the top of the limit pin 201a, and the baffle is fixed to one side of the movable plate 201c. When the movable block 104 moves to the bottom of the limit pin 201a, the baffle can be used to limit the limit pin 201a to prevent the limit pin 201a from flipping upward, thereby limiting the movable block 104 and preventing the main platform 102 from continuing to move upward.

[0035] A driving groove corresponding to the movable bar 201f is opened on the movable plate 201g. When the movable plate 201c moves, the movable bar 201f will be driven to move. The movable bar 201f can squeeze the driving groove to drive the movable plate 201g to move. When the movable bar 201f moves to the limiting groove on one side of the driving groove, the movable plate 201g will return to its original position, so that the movable bar 201f is engaged with the limiting groove, so that the movable bar 201f can be limited to prevent the movable block 104 from returning to its original position. A return spring is fixed at one end of the movable bar 201f, and the return spring is fixed to the inner wall of the positioning box 202h. The movable bar 201f can apply a squeezing force to the return spring when moving. When the other movable plate 201c is moved to move the main platform 102 to other positions, the movable plate 201c will move. The movable bar 201f corresponding to it moves. At this time, the movement of the movable bar 201f will squeeze the corresponding driving groove to make the movable plate 201g move again, and then the movement of the movable plate 201g will separate the limiting groove from the engaged movable bar 201f, and then the rebound force of the reset spring will drive the movable bar 201f to return to its original position. At this time, the moved movable bar 201f will be engaged with the corresponding limiting groove, thereby completing the limitation of another movable plate 201c, so that the main platform 102 can be moved to other positions. When the main platform 102 squeezes the anti-fall pin 201b from above, the anti-fall pin 201b can be flipped downward, so that the moving block 104 moves to the bottom of the anti-fall pin 201b, thereby preventing the main platform 102 from moving upward, thereby completing the limitation of the movement of the main platform 102.

[0036] The lifting assembly 300 is arranged on the extrusion rod 201e, and includes a lifting member 301, including a lifting plate 301a, a threaded rod 301b, a first bevel gear 301c, a second bevel gear 301d, a first pulley 301e, a second pulley 301f, a belt 301g and a motor 301h.

[0037] When it is necessary to move the extrusion rod 201e to different heights to extrude the protrusion 201d, by starting the motor 301h, the motor 301h can drive the second pulley 301f to rotate, the second pulley 301f drives the belt 301g to rotate, the belt 301g drives the first pulley 301e to rotate, the rotation of the first pulley 301e drives the second bevel gear 301d to rotate, the rotation of the second bevel gear 301d drives the first bevel gear 301c to rotate, and the first bevel gear 301c drives The threaded rod 301b rotates, and the threaded rod 301b drives the lifting plate 301a to move. The movement of the lifting plate 301a can drive the extrusion rod 201e to move to different heights, so that the protrusions 201d of different heights can be squeezed. A positioning groove is provided on one side of the positioning box 202h, and a slider is provided on one side of the lifting plate 301a. When the lifting plate 301a moves, it will drive the slider to slide in the positioning groove, so as to support the lifting plate 301a and prevent the lifting plate 301a from shifting when moving.

[0038] Example 2 Reference Figure 1 to Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0039] Specifically, the limiting assembly 200 also includes a moving part 202, a first torsion spring 202a is fixed to one side of the limiting pin 201a, and the first torsion spring 202a is fixed to the inner wall of the moving plate 201c. A first spring 202b is fixed to one side of the anti-fall pin 201b, and the first spring 202b is fixed to the inner wall of the moving plate 201c.

[0040] A first torsion spring 202a and a first spring 202b are provided on each limit pin 201a and anti-fall pin 201b. When the limit pin 201a is squeezed and moved, a torsional force can be applied to the first torsion spring 202a, and the limit pin 201a can be driven to return to its original position by the rotational force of the first torsion spring 202a. When the anti-fall pin 201b is squeezed, a squeezing force can be applied to the first spring 202b, and the anti-fall pin 201b can be driven to return to its original position by the rebound force of the first spring 202b.

[0042] The positioning frame 202e is fixed to the top of the lifting plate 301a. When the lifting plate 301a moves, the positioning frame 202e is driven to move, and the positioning frame 202e drives the rotating wheel 202c to move. The movement of the rotating wheel 202c drives the squeezing rod 201e to move, so that the squeezing rod 201e moves to the corresponding side of the protrusion 201d. Then, the moving rope 202d can be pulled at this time, and the moving rope 202d can drive the rotating wheel 202c to rotate. When the rotating wheel 202c rotates, it drives the turntable 202f to rotate. The rotation of the turntable 202f can apply a torsional force to the second torsion spring 202g. The rotation of the rotating wheel 202c drives the squeezing rod 201e to move, so that the protrusion 201d can be squeezed. Then, when the moving rope 202d is released, the rotating wheel 202c can be driven to return to its original position through the rotation force of the second torsion spring 202g for next use.

The movement of the movable plate 201g can separate the limiting groove from the movable bar 201f engaged with it, and then the movable bar 201f is driven to return to its original position by the rebound force of the reset spring. When the extrusion bar 203a is pressed, the third spring 203b can be applied with an extrusion force. After the movable bar 201f returns to its original position, the extrusion bar 203a is released, and the rebound force of the third spring 203b drives the extrusion bar 203a to return to its original position for next use. The support sleeve 203c is used to support the extrusion bar 203a to prevent the extrusion bar 203a from shifting during movement.

When the supporting frame 101 moves to the target position, the electric supporting legs 108 are extended to lift the supporting frame 101 as a whole so that the wheels are off the ground. After the electric supporting legs 108 are extended to lift the supporting frame 101 as a whole so that the wheels are off the ground, the supporting frame 101 is completely out of the movable state of the wheels, thereby ensuring that it will not move due to unexpected external forces or uneven ground during operation. The supporting diagonal rods 107 are flipped over to contact the ground to further enhance the stability of the supporting frame 101. The supporting diagonal rods 107 and the ground form a triangular supporting structure, which has extremely high stability in mechanics. It can effectively resist external forces from all directions to prevent the supporting frame 101 from shaking or tilting during operation.

[0059] When in use, when the main platform 102 needs to be moved to a specified height, the height of the main platform 102 needs to be positioned first, and the motor 301h is started. When the motor 301h rotates, it drives the second pulley 301f to rotate, and the second pulley 301f drives the belt 301g to rotate, and the belt 301g drives the first pulley 301e to rotate. The rotation of the first pulley 301e drives the second bevel gear 301d to rotate, and the rotation of the second bevel gear 301d drives the first bevel gear 301c to rotate, and the first bevel gear 301c rotates. The wheel 301c drives the threaded rod 301b to rotate, and the threaded rod 301b drives the lifting plate 301a to move. The movement of the lifting plate 301a will drive the positioning frame 202e to move. The movement of the positioning frame 202e can drive the extrusion rod 201e to move to a specified height, and when the second pulley 301f rotates, the rotating rod 302b will be driven to rotate. The rotation of the rotating rod 302b will drive the winding drum 302a to rotate, and the moving rope 202d can be unwound by the rotation of the winding drum 302a.

[0060] After the squeezing rod 201e is moved to the specified position, the moving rope 202d is pulled, and the movement of the moving rope 202d will drive the rotating wheel 202c to rotate. When the rotating wheel 202c rotates, it can drive the turntable 202f to rotate. The rotation of the turntable 202f can apply a torsional force to the second torsion spring 202g. The rotation of the rotating wheel 202c drives the squeezing rod 201e to move, so that the protrusion 201d can be squeezed. Then when the moving rope 202d is released, the rotation force of the second torsion spring 202g can drive the rotating wheel 202c to return to its original position for the next use.

[0061] When the protrusion 201d is squeezed, the protrusion 201d can be moved, and the movement of the protrusion 201d will drive the moving plate 201c to move. The movement of the moving plate 201c will drive the limiting pin 201a and the anti-falling pin 201b to move, so that the two are moved to one side of the moving block 104, so that the moving block 104 can be limited, and when the moving plate 201c moves, it will drive the movable bar 201f to move, and the movable bar 201f can squeeze the driving groove to drive the movable plate 201g to move, and the movement of the movable plate 201g can apply a pulling force to the second spring 202j, and at the same time, the movement of the movable bar 201f can apply a squeezing force to the reset spring, and when the movable bar 201f moves to the limiting groove on one side of the driving groove, the movable plate 201g will return to its original position through the rebound force of the second spring 202j, so that the movable bar 201f and the limiting groove are in a fixed position. When the main platform 102 moves, the moving block 104 will be driven to move. After the moving block 104 moves to the bottom of the anti-fall pin 201b, the anti-fall pin 201b can be squeezed. When squeezing the anti-fall pin 201b, a squeezing force can be applied to the first spring 202b. When the moving block 104 moves to separate from the anti-fall pin 201b, the anti-fall pin 201b can be driven to return to its original position by the rebound force of the first spring 202b, thereby limiting the moving block 104 and preventing the main platform 102 from descending. At this time, the baffle at the top of the limit pin 201a will limit it, thereby preventing the main platform 102 from continuing to rise.
