DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-8 , this utility model provides two technical solutions:

[0030] The first embodiment: a circulating frame, including a frame 1 for adapting to unloading ports of different heights, and a set of adjustment mechanisms 2 are provided above the frame 1 for adjusting the cargo loading space. The frame 1 includes:

[0031] The bottom frame unit 11 includes a bottom frame 111. A connecting seat 113 is fixedly mounted on one end of the bottom frame 111. A supporting rod 114 is rotatably mounted inside the connecting seat 113. The supporting rod 114 has a plurality of through holes 115 formed inside for supporting the top frame unit 12.

[0032] The top frame unit 12 is disposed above the bottom frame unit 11 and is used for loading goods.

[0033] In this embodiment, a plurality of support blocks 112 are fixedly mounted on the top of the bottom frame 111 , and a fixing ear 116 is fixedly mounted on the upper end of one end of the bottom frame 111 .

[0034] The user lifts one end of the movable frame 121 so that the movable frame 121 is connected to the bottom frame 111 and rotated and lifted. When the movable frame 121 is lifted, the supporting rotating rod 114 rotates, and the sleeve 125 slides on the outside of the supporting rotating rod 114. As the angle of the supporting rotating rod 114 changes, the rotation angle of the sleeve 125 changes accordingly, and the sleeve 125 and the supporting rotating rod 114 are fixed by pins to support the movable frame 121, so that the frame can adapt to unloading ports of different heights, thereby achieving the flexibility of the frame.

[0035] In this embodiment, the top frame unit 12 includes a movable frame 121 rotatably mounted above the bottom frame 111, and a sleeve 125 is rotatably mounted on one end of both sides of the movable frame 121, and the sleeve 125 is slidably inserted into the interior of the sleeve 125, and the sleeve 125 and the supporting rotating rod 114 are fixed by a pin passing through the sleeve 125 and inserted into the through hole 115.

[0036] The sleeve 125 slides outside the support rod 114 , and as the angle of the support rod 114 changes, the rotation angle of the sleeve 125 changes accordingly, and the sleeve 125 and the support rod 114 are fixed by pins to support the movable frame 121 .

[0037] In this embodiment, a plurality of reinforcing rods 123 are fixedly installed inside the movable frame 121 for strengthening the supporting force of the movable frame 121, and two first support plates 122 are fixedly installed above the movable frame 121 for supporting the goods. A group of connecting ears 124 are fixedly installed on the outside of one end of the movable frame 121.

[0038] The connecting ears 124 and 126 overlap and contact each other, and a pin penetrates through the connecting ears 124 and 126 to fix the movable frame 121 to the bottom frame 111 .

[0039] The second embodiment is mainly different from the first embodiment in that: the adjustment mechanism 2 includes a sliding unit 21, a cargo blocking unit 22 and a fixed unit 23, and the sliding unit 21 includes two sets of track bars 211 fixedly installed inside the movable frame 121, a socket 212 is opened inside the track bar 211, and a sliding plate 213 is slidably installed inside the socket 212, and a second support plate 214 is fixedly installed on the top of the sliding plate 213, and a rectangular groove 215, a limit groove 216 and a circular hole 217 are opened inside the sliding plate 213.

[0040] The sliding block 231 slides inside the limiting groove 216 , and the inserting post 232 slides inside the circular hole 217 .

[0041] In this embodiment, the cargo blocking unit 22 includes a set of fixing seats 221 fixedly mounted on the outside of the second support plate 214 , and a blocking seat 222 is fixedly mounted on the inner side of the fixing seat 221 via a latch 223 .

[0042] The blocking seat 222 is fixed to the fixing seat 221 via the latch 223 , and the fixed position between the blocking seat 222 and the fixing seat 221 is adjustable, thereby achieving an adjustable cargo blocking position.

[0043] The cam 238 is actuated to move the lever 232 in a direction of rotation so as to allow the lever 232 to move relative to the stopper 232 and to engage the stopper 233. The cam 238 is actuated to engage the stopper 233 so as to engage the stopper 233. When the cam 238 is engaged, the stopper 233 is engaged with the stopper 234 and engages with the stopper 235. When the cam 238 is engaged, the stopper 233 is engaged with the stopper 234 and engages with the stopper 235. When the cam 238 is engaged, the stopper 233 is engaged with the stopper 234 and engages with the stopper 235.

[0044] The user turns the handwheel button column 239, driving the rotating rod 238 to rotate synchronously. The rotating rod 238 pulls the two sliding blocks 231 to move synchronously toward each other through the linkage rod 237, and the baffle at one end of the sliding column 235 squeezes the spring 236. At this time, the plug 232 is pulled out from the inside of the socket 212 and slides inside the track bar 211 through the sliding plate 213 to adjust the overall position of the adjustment mechanism 2. Afterwards, the spring 236 pushes the sliding column 235 to move through its own elastic force, and the sliding column 235 pushes the sliding block 231 to move synchronously through the mounting ear 234, so that the plug 232 is inserted into the inside of the socket 212 to fix the position of the adjustment mechanism 2.

[0045] In this embodiment, a ramp plate 3 is disposed at one end of the vehicle frame 1 , and a support plate 4 is disposed on the top of the ramp plate 3 .

[0046] The ramp plate 3 is placed at the raised end of the movable frame 121 to facilitate loading of goods, and the support plate 4 is placed on the top of the movable frame 121 to increase the supporting area for the goods.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] During operation, first, according to the height of the unloading port, one end of the movable frame 121 is raised so that the movable frame 121 is connected to the bottom frame 111 and rotated and raised. When the movable frame 121 is raised, the support rod 114 rotates, and the sleeve 125 slides outside the support rod 114. As the angle of the support rod 114 changes, the rotation angle of the sleeve 125 changes accordingly. The sleeve 125 is fixed to the support rod 114 by a pin to support the movable frame 121.

[0049] Then, according to the specifications of the cargo, the user turns the handwheel button column 239, driving the rotating rod 238 to rotate synchronously, and the rotating rod 238 pulls the two sliding blocks 231 to move synchronously toward each other through the linkage rod 237, and the baffle at one end of the sliding column 235 squeezes the spring 236. At this time, the plug column 232 is pulled out from the inside of the socket 212 and slides inside the track bar 211 through the sliding plate 213 to adjust the overall position of the adjusting mechanism 2. Afterwards, the spring 236 pushes the sliding column 235 to move through its own elastic force, and the sliding column 235 pushes the sliding block 231 to move synchronously through the mounting ear 234, so that the plug column 232 is inserted into the inside of the socket 212 to fix the position of the adjusting mechanism 2 and complete the operation of adjusting the space on the frame. Afterwards, two ramp plates 3 are placed at the raised end of the movable frame 121 to facilitate loading of cargo, and a support plate 4 is placed on the top of the movable frame 121 to increase the support area for the cargo.
