DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be further described in detail below in combination with the preferred embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2This invention discloses a multifunctional foldable transport platform, comprising a load-bearing transport frame 1, a front rotary folding frame 2 and a rear rotary folding frame 3 symmetrically distributed on both sides of the load-bearing transport frame. One side of each of the front and rear rotary folding frames is rotatably connected to the load-bearing transport frame, allowing the transport platform to be in a folded or unfolded state. In this embodiment, one side of each of the front and rear rotary folding frames is rotatably connected to the load-bearing transport frame via a rotary pin 4. The slewing pins are respectively inserted into pin holes on the load-bearing frame and the front slewing frame, and into pin holes on the rear slewing frame, allowing the front and rear slewing frames to rotate 180° around the slewing pins. Furthermore, the ends of the slewing pins on the front and rear slewing frames are provided with limiting holes, and type B cotter pins are fitted into these limiting holes to prevent the slewing pins from dislodging from the aforementioned pin holes during use. This affects the use of the transport platform; locking components 8 are provided between the load-bearing transport frame and the front rotating folding frame, and between the load-bearing transport frame and the rear rotating folding frame, to maintain the transport platform in its folded or unfolded state after it has been folded or unfolded. Specifically, the load-bearing transport frame has two symmetrically distributed first locking holes 106 and two symmetrically distributed second locking holes 107, and the front rotating folding frame and the rear rotating folding frame both have a third locking hole 12 and a fourth locking hole 107. Hole 13: When the transport platform is in the unfolded state, the locking components are respectively installed in the first locking hole 106 and the third locking hole 12. When the transport platform is in the folded state, the locking components are installed in the second locking hole 107 and the fourth locking hole 13. In this embodiment, the locking component is a limit locking quick release pin, and one end of the limit locking quick release pin is provided with a stop block to prevent the limit locking quick release pin from coming out of the pin hole; the other end is provided with a loop handle equipped with an anti-loss rope to prevent the limit locking quick release pin from being lost when it is taken out.

[0025] Please see Figure 3The load-bearing transport frame includes angle steel 101, rectangular welded pipes, and circular welded pipes, and is manufactured by welding. Specifically, the load-bearing transport frame includes symmetrically distributed angle steels extending in the front-to-back direction, a frame body 102 located between the angle steels, and a set of connecting pipe groups (rectangular welded pipes) spaced apart between one side of the frame body and one side of the corresponding angle steel. Each connecting pipe group includes two adjacent sub-connecting pipes 103 and a clearance hole formed by the sub-connecting pipes. Specifically, the connecting pipe group near the front rotating folding frame forms a first clearance hole 104, and the connecting pipe group near the rear rotating folding frame forms a second clearance hole 105. Weight-reducing holes are provided on the horizontal surface of the angle steel to reduce the weight of the transport platform. In this embodiment, elliptical weight-reducing holes are used. Symmetrically distributed limiting handles 7 are provided on the vertical surface of the angle steel for limiting the self-locking tightening straps 9 when the goods 10 are fixed. (Cargo can be locked in both folded and unfolded states), and meets the needs of operators for hand-carrying; the angle steel is provided with two symmetrically distributed first locking holes and two symmetrically distributed second locking holes, and the angle steel is also provided with four limiting plates 108 spaced apart along the length direction. The limiting plates and the vertical surface of the angle steel form limiting grooves for the edge parts of the front frame and the rear frame to be placed when the platform is folded or unfolded, so as to enable the front rotary folding frame and the rear rotary folding frame to quickly fold to the corresponding positions in the folded or unfolded state; the limiting plates are provided with fifth locking holes 1081 that cooperate with the corresponding first locking holes and corresponding second locking holes; it is beneficial for the aforementioned locking parts to quickly pass through the first locking holes, third locking holes and fifth locking holes to achieve quick locking in the unfolded state of the transport platform, or the second locking holes, fourth locking holes and fifth locking holes to achieve quick locking in the folded state of the transport platform.

[0026] Please see Figure 4 and Figure 5 The front and rear rotating folding frames are both made of rectangular and circular welded pipes and manufactured by welding. Symmetrically distributed wheels are provided on both the front and rear rotating folding frames. Please refer to [further details omitted]. Figure 3 The load-bearing frame is provided with clearance holes for the aforementioned traveling wheels to pass through when the transport platform is folded. Specifically, the front rotating folding frame is provided with heavy-duty directional wheels 5 that pass through the first clearance hole. In this embodiment, the heavy-duty directional wheels include caster mounting brackets and directional casters. The directional casters are fastened to the caster mounting brackets by bolts and nuts. The rear rotating folding frame is provided with heavy-duty universal brake wheels 6 that pass through the second clearance hole. The heavy-duty universal brake wheels include caster mounting brackets and universal brake casters. The universal brake casters are fastened to the caster mounting brackets by bolts and nuts and have 360° rotation and locking braking functions, so that the transport platform of the present invention can move and turn on the ground in both the unfolded and folded states.

[0027] As a preferred embodiment of the present invention, the aforementioned limiting handle 7 is U-shaped and has threads at the end, and is fastened to the load-bearing frame, the front rotating folding frame and the rear rotating folding frame by means of nuts.

[0028] Please see Figure 6 As an embodiment of the present invention, when the goods 10 are placed on the transport platform of the present invention and the transport platform is in the unfolded state, the self-locking tightening straps 9 can pass through the limit handles on the load-bearing transport frame, the front rotating folding frame, and the rear rotating folding frame to achieve a fixed and limited function; when the transport platform is in the folded state, the self-locking tightening straps can pass through the upper limit handles on both sides of the load-bearing transport frame that are not rotatably connected to the front rotating folding frame and the rear rotating folding frame to achieve a fixed and limited function, so that the transport platform of the present invention can meet the needs of goods binding and limiting in both the unfolded and folded states.

[0029] Please see Figure 7 As an embodiment of the present invention, when the transport platform of the present invention is performing the operation of hoisting goods (after the goods have been fixed), the net-type hoisting net 11 can be used to gather the items for easy hook mounting, so as to prevent the goods from falling off the transport platform.

[0030] In other embodiments of the present invention, the slewing pin in this embodiment can be replaced by a stepped bolt.

[0031] In other embodiments of the present invention, other locking components may be used instead of the limit locking quick-release pin in this embodiment, such as a spring positioning pin.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the design and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
