With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Example 1:

referring to fig. 1 to 3, as a preferred embodiment of the present invention, there is provided a fork lift truck with adjustable fork carrying height, comprising a fork 1, a raising plate 3 and a locking mechanism 4, wherein the raising plate 3 is a plate-shaped structure with a contour matching the contour of the fork 1, two forks 1 are each provided with a raising plate 3, the raising plate 3 is rotatably disposed above the fork 1 and can be turned over and raised (as shown by a solid line in fig. 1 and 2) or laid down on the upper top surface of the fork 1 (as shown by a dotted line in fig. 1 and 2) relative to the fork 1, and the locking mechanism 4 is configured to lock the raising plate 3 in the raised state, so that, when the fork 1 needs to be raised in carrying height, the locking mechanism 4 is unlocked to turn over the raising plate 3 downward and lay down on the fork 1, i.e. raise the carrying surface of the fork 1, and increase the ground clearance of the fork 1, thereby making up the deficiency of the lifting height; when the heightening plate 3 is not needed, the heightening plate 3 is turned over and erected, and the locking mechanism 4 is used for locking the heightening plate 3, so that the heightening plate 3 can be folded. This embodiment has not only realized the adjustment of the bearing height of fork 1 through setting up as above, also makes the bed hedgehopping board 3 can be folded up when not using, neither influences the normal work of fork 1, also can reduce the space occupation of bed hedgehopping board 3.

The battery box 2 is provided at the rear side of the fork 1, and in this embodiment, the raising plate 3 is rotatably connected to the fork 1 at a rear position of the upper surface thereof by a hinge 5. In other embodiments, the step-up plate 3 may be hinged to the battery box 2, or a bracket may be provided above the fork 1, and the step-up plate 3 is hinged to the bracket, but this embodiment may rotatably connect the step-up plate 3 hinge 5 to the upper side of the rear end of the fork 1 to facilitate the assembly of the step-up plate 3. In addition, in this embodiment, when the raised plate 3 is turned over and erected, it can also be attached to the battery box 2, so as to protect the battery box 2.

The locking mechanism 4 is fixedly arranged on the battery box 2, the locking mechanism 4 comprises a rotating frame 41, a locking frame 42, a rotating shaft 43, a nut 44, a bolt 45 and a gasket 46 sleeved on the bolt 45, the rotating frame 41 and the locking frame 42 are fixedly connected on the battery box 2 at intervals, the rotating shaft 43 is rotatably connected on the rotating frame 41, the nut 44 is fixedly welded on the peripheral surface of the rotating shaft 43 (other embodiments can also adopt fixed connection means such as bonding and the like), the bolt 45 is screwed on the nut 44, so that the bolt 45 can swing relative to the rotating frame 41 through the rotating shaft 43, the locking frame 42 is arranged on the swing path of the bolt 45, and a clamping groove for the bolt 45 to swing and clamp is arranged on the locking frame 42. When the bolt 45 is clamped on the locking frame 42, the bolt 45 can be clamped and fixed with the locking frame 42 by screwing the bolt 45, and further the locking and buckling of the locking mechanism 4 are realized, and the bolt 45 can be unlocked from being clamped and fixed with the locking frame 42 by unscrewing the bolt 45. The washer 46 and the threaded connection of the bolt 45 and the nut 44 enable tightness adjustment of the locking mechanism 4. The locking mechanism 4 adopted in the embodiment has the advantages of low cost, easy manufacture, small occupied space and convenient implementation.

In this embodiment, the lock mechanism 4 is fixed to the battery box 2 at the rear end of the fork 1. However, in other embodiments, the locking mechanism 4 may be disposed at other positions, such as on the pallet fork 1 and on the side of the forklift, and the specific structure of the locking mechanism may be flexibly selected according to the specific installation position, and besides the locking mechanism 4 provided in this embodiment, any other locking mechanism in the art may be adopted, such as a locking pin (shift pin) mechanism, a clamping type locking mechanism (such as pneumatic clamping, electric clamping, and the like), a magnetic type locking mechanism, a friction type locking mechanism, and the like, which can limit the rotation of the bed plate 3, is feasible. The locking mechanism 4 is provided on the battery case 2 in this embodiment to facilitate the installation thereof.

As shown in fig. 2, a first opening 31 and a second opening 32 are provided on the raising plate 3, so that the raising plate 3 correspondingly exposes the push rod mechanism and the carrier wheel of the pallet fork 1 when laid down, and the maintenance of the push rod mechanism and the carrier wheel is facilitated. The first opening 31 and the second opening 32 are adjacently arranged and separated by a rib 33, and the locking mechanism 4 locks the elongated rib 33 to lock the raised plate 3 in the standing state. The arrangement is such that the locking of the raised plate 3 is easily achieved, and in conjunction with fig. 3, the first opening 31 and the second opening 32 can also correspondingly give way for the rotating frame 41 and the locking frame 42, respectively.

Example 2:

referring to fig. 4, the present embodiment provides a forklift with adjustable fork carrying height, which has a structure similar to that of embodiment 1 and has the same technical effects as the same structure, and the only difference is that the body of the raised board 3A of the present embodiment is further provided with a folding hinge 6, so that the raised board 3A can be folded into a multi-layer structure, thereby further accommodating the raised board 3A.
