[0024] The following description, in conjunction with the accompanying drawings, further illustrates the adjustable mobile manual material lifting platform of this utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0026] See appendix Figure 1-7 As shown in the figure, this embodiment discloses a mobile manual material lifting platform with adjustable structure, characterized by including a lifting mast assembly 1, a hand crank mechanism 2 for adjusting the lifting of the lifting mast assembly 1, a rope 3 connecting the hand crank mechanism 2 and the lifting mast assembly 1, and a mobile base 4 installed at the bottom of the lifting mast assembly 1 to drive the lifting mast assembly 1 to move vertically or horizontally; the mobile base 4 includes a mobile base 401, a support frame 402 connecting the mobile base 401 and the lifting mast assembly 1, several universal wheels 403 installed at the bottom of the mobile base 401 to drive the lifting mast assembly 1 to move vertically, and large pulleys 404 and adjustable-angle horizontal wheels 405 installed at both ends of the support frame 402 to allow the lifting mast assembly 1 to move horizontally; by cranking the hand crank mechanism 2, the lifting mast assembly 1 is driven to move up and down, and the lifting mast assembly 1 drives the material to move up and down, thereby facilitating the lifting and lowering of the material.

[0027] The vertical movement of the lifting mast assembly 1 can be achieved by moving the casters 403 on the base 401. By flipping the base 401 and the lifting mast assembly 1, the large pulleys 404 and horizontal wheels 405 on the support frame 402 can be brought to the ground, which can drive the lifting mast assembly 1 to move horizontally. This makes it convenient to use in places of different sizes, expands the range of use, and also improves the ease of movement of the lifting mast assembly 1.

[0028] See appendix Figure 2 As shown, the support frame 402 is equipped with an adjustment plate 406 for adjusting the angle of the planar wheel 405 via pins, and mounting through holes 407 at different angles on the adjustment plate 406; the adjustment plate 406 is equipped with a mounting rod 408 for mounting the planar wheel 405; the two ends of the mounting rod 408 are also equipped with handles 409 for moving the platform; by using the handles 409, the movable base 401 and the lifting mast assembly 1 can be moved vertically, thereby facilitating the movement of the movable base 401 and the lifting mast assembly 1; by using pins to align the mounting rod 408 with the mounting through holes 407 at different angles on the adjustment plate 406, it is convenient for the planar wheel 405 to be installed at different angles, thus reducing the overall volume.

[0029] See appendix Figure 1 As shown, it also includes side legs 5 that are foldably mounted on both sides of the movable base 401 via a pivot, providing auxiliary support to the movable base 401; a fixing plate 501 mounted on the lifting mast assembly 1 for the side legs 5; a swing rod 502 rotatably mounted on the fixing plate 501; and a support rod 503 with one end passing through the swing rod 502 and movably connected to the side legs 5. Each side leg 5 is equipped with an auxiliary caster wheel 504. When the movable base 401 is in a large area, the side legs 5 provide auxiliary support. When the movable base 401 is in a narrow area, the side legs 5 can be folded and mounted on the movable base 401, reducing the footprint of the movable base 401 and thus expanding its range of use. By folding the side legs 5 along the pivot, while the swing rod and support rod 503 move along the direction of the swing rod 502, and the swing rod 502 is rotated, the swing rod 502 is made parallel to the folded side legs 5, thus facilitating the folding of the side legs 5.

[0030] See appendix Figure 3-5As shown, the lifting mast assembly 1 includes a fixed mast 101 connected to the support frame 402 and fixed to the hand-crank mechanism 2, a lifting mast 102 that can be lifted and lowered on the fixed mast 101, a short mast 103 that can be lifted and lowered on the lifting mast 102, and a material rack 104 installed on the short mast 103; pulleys 105 are installed on the fixed mast 101, the lifting mast 102, and the short mast 103 to facilitate the winding of the rope 3; a fixed end 106 for fixing one end of the rope 3 is also installed at the top of the lifting mast 102; one end of the rope 3 is fixed to the fixed end 106. The other end passes through pulley 105 and is wound around hand crank mechanism 2; guide pulleys 107 are installed on the fixed mast 101, lifting mast 102 and short mast 103; guide grooves 108 adapted to guide pulleys 107 are provided on the fixed mast 101 and lifting mast 102; by sliding the guide pulleys 107 on the lifting mast 102 and short mast 103 along the guide grooves 108 on the lifting mast 102 and fixed mast 101 respectively when the lifting mast 102 and short mast 103 are raised and lowered, the lifting mast 102 and short mast 103 are guided.

[0031] See appendix Figure 6 As shown, the hand-cranked mechanism 2 includes a fixed housing 201, a two-hand crank 202 rotatably mounted inside the fixed housing 201, a rope winding wheel 206, and a gear set connecting the rope winding wheel 206 and the two-hand crank 202. The gear set includes a drive gear 203 mounted on the two-hand crank 202, a transmission gear 204 meshing with the drive gear 203 and rotatably mounted on the fixed housing 201, and a driven gear 205 mounted on the rope winding wheel 206 and meshing with the transmission gear 204. By rotating the two-hand crank 202, the two-hand crank 202 drives the drive gear 203 to rotate, the drive gear 203 drives the transmission gear 204 to rotate, the transmission gear 204 drives the driven gear 205 to rotate, and the driven gear 205 drives the rope winding wheel 206 to rotate, thereby facilitating the winding or releasing of the rope 3 and raising or lowering the lifting mast assembly 1.

[0032] In the process of using this utility model, firstly, the material to be lifted is placed on the material rack 104. Then, the two-hand crank 202 is rotated, which drives the drive gear 203 to rotate. The drive gear 203 drives the transmission gear 204 to rotate, which in turn drives the driven gear 205 to rotate. The driven gear 205 drives the rope winding wheel 206 to rotate, winding the rope 3. The rope 3 pulls the short mast 103 to slide upward along the guide groove 108 on the lifting mast 102. The short mast 103 lifts the material rack 104 upward until the short mast 103 is raised to the highest point of the lifting mast 102. Continuing to rotate the two-hand crank 202, the short mast 103 pulls the lifting mast 102 upward along the guide groove 108 of the fixed mast 101. Raise the lifting mast 102 until it reaches the top of the fixed mast 101. When it needs to be lowered, simply rotate the two-hand crank 202 in the opposite direction. When the material lifting platform is moved to a different location, if it is too high during the movement, it will be impossible to maintain the material lifting platform at the corresponding height. In this case, flip the moving base 401 so that the large pulley 404 and the horizontal wheel 405 on the support frame 402 of the moving base 401 touch the ground. Then, the lifting mast assembly 1 can be moved horizontally. When moving horizontally, the mounting rod 408 of the fixed horizontal wheel 405 should be adjusted on the adjusting plate 406 to be at a 90-degree angle with the lifting mast assembly 1. When moving vertically, the mounting rod 408 can be adjusted on the adjusting plate 406 to be tilted and folded.

[0033] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
