By rotating the first fork plate 223 to be coplanar with the second fork plate 224 by the transmission arm 225, the first fork plate 223 is pushed rearward, and the rotating wheel 226 moves rearward in the side wall of the second fork plate 224, so that the tenon 2231 on the first fork plate 223 is inserted into the mortise 2241 on the second fork plate 224. The engagement of the tenon 2231 with the mortise 2241 allows the first fork plate 223 to be stably fixed to the second fork plate 224, which facilitates the transportation of a pallet having a large size.

After the tenon 2231 is separated from the mortise 2241 by pushing the first fork plate 223 forward, the first fork plate 223 is rotated to make the first fork plate 223 fold over and fit on the bottom surface of the second fork plate 224, and the first fork plate 223 is pushed to make the plug-in rod 2242 be inserted into the plug hole on the tenon 2231, so that the first fork plate 223 is fixed on the second fork plate 224. On the one hand, the length of the fork 22 is reduced, the pallet with small size can be conveniently transported by forking, on the other hand, the folding and the storage of the fork 22 are realized to a certain extent, the space occupancy rate is reduced, and the safety is improved.

Referring to fig. 4, the connection member 33 includes a U-shaped plug 331, a fixing hole 2211 is formed in a sidewall of the horizontal section 221 for inserting one end of the plug 331, and the other end of the plug 331 is telescopically and rotatably disposed in a sidewall of the vertical section 222. When the fork 22 is folded, the horizontal section 221 is rotated to make one surface of the horizontal section 221 and the vertical section 222 fit with each other, and then the latch 331 is pulled and rotated to make the other end of the latch 331 inserted into the fixing hole 2211, thereby fixing the horizontal section 221 on the vertical section 222. When the pallet fork 22 needs to be used, the bolt 331 is pulled and rotated so that one end of the bolt 331 is separated from the fixing hole 2211, after the horizontal section 221 rotates 90 degrees relative to the vertical section 222, the bottom surface of one end of the horizontal section 221 abuts against the lower part of the rotating rod 311 on the connecting block 31, so that the horizontal section 221 is fixed, and meanwhile, the arrangement of the reinforcing rod 32 further increases the structural strength of the horizontal section 221 on the vertical section 222.

Further, referring to fig. 5, the connecting member 33 further includes an elastic member 332 and a thrust plate 333, and in this embodiment, the elastic member 332 is preferably a spring. A cavity 2221 is formed in the vertical section 222, a through hole 2222 for communicating the cavity 2221 with the outside is formed in the outer side wall of the vertical section 222, the thrust plate 333 is slidably disposed in the cavity 2221, and one end of the plug 331 passes through the through hole 2222 and is fixedly connected with the thrust plate 333. The elastic member 332 is sleeved on the plug 331 and disposed on the inner walls of the thrust plate 333 and the cavity 2221 close to the through hole 2222, and in a natural state of the elastic member 332, one end of the plug 331 away from the thrust plate 333 elastically abuts against the outer side wall of the vertical section 222.

When the horizontal section 221 is rotated to engage with one surface of the vertical section 222, the pin 331 is pulled outward, and the pin 331 drives the thrust plate 333 to move toward the through hole 2222, at this time, the elastic member 332 is compressed to store elastic force. The latch 331 is rotated such that the other end of the latch 331 is inserted into the fixing hole 2211, releasing the external force applied to the latch 331. The elastic member 332 naturally rebounds to provide power to drive the thrust plate 333 to move toward the cavity 2221 away from the through hole 2222, and at the same time, drives the other end of the plug 331 to abut against the fixing hole 2211 of the horizontal section 221, thereby further increasing the stability of the fixing of the horizontal section 221 on the vertical section 222.

The implementation principle of the embodiment is as follows: when the forklift is used for transferring goods, the forklift is driven to enable the pallet fork 22 to be inserted into the pallet, then the lifting oil cylinder 211 is driven to enable the goods blocking frame 23 to drive the pallet fork 22 to move up and down, and therefore the goods on the pallet can be conveniently conveyed to the designated position. According to the pallets with different sizes, the positions of the two forks 22 on the goods blocking frame 23 are adjusted, so that the transfer of the pallets can be met. When the forklift is not used, the horizontal section 221 is driven to rotate around the connecting block 31 in a direction close to the vertical section 222, one end of the reinforcing bar 32 slides on the sidewall of the vertical section 222, and the horizontal section 221 is fixed to the vertical section 222 by adjusting the connecting member 33 when the horizontal section 221 and one surface of the vertical section 222 are engaged with each other.

When it is desired to use the fork, the horizontal section 221 and the vertical section 222 are perpendicular to each other by opening the connecting member 33, and the reinforcing bar 32 increases the structural strength between the horizontal section 221 and the vertical section 222, so that the fork 22 can support a load having a large weight. The horizontal section 221 is rotatably arranged on the vertical section 222 through the connecting block 31, and the connecting piece 33 for fixing the horizontal section 221 is arranged at one end of the vertical section 222, so that the folding function of the pallet fork 22 is realized, the space occupancy rate of the forklift is reduced, and the safety is improved.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
