As shown in fig. 1, the utility model provides a fork truck fender frame with adjustable height explains on taking this fork truck fender frame to install one of them type tray truck in the fork truck as an example in this embodiment, because the tray truck does not have lifting formula fork truck's portal to exist, when consequently carrying high goods, the goods takes place to empty more easily. But is not limited to pallet jacks and may be used with other types of forklifts.

Referring to fig. 1 to 3, the height adjustable forklift truck fender includes a fender rack body 10 and at least one lifting device 20, wherein the lifting device 20 is fixedly installed to a fork carriage 30 of a pallet truck, and the lifting device 20 has a lifting rod 200 capable of performing a telescopic motion with respect to the ground, the fender rack body 10 is fixedly installed to the lifting rod 200 to adjust the height of the fender rack body 10 as the lifting rod 200 is capable of performing a telescopic motion with respect to the ground, so that the height of the fender rack body 10 can be adjusted according to the actual height of a carried cargo to eliminate the risk of the cargo of different heights falling backwards, ensure the safety of a driver, and only one pallet is required to carry the cargo of different heights, and a plurality of pallets need not be provided, thereby reducing the cost. The fork carriage as referred to herein is a generic term for the battery box and the fork leg weld.

The shelf body 10 in this embodiment is shown in fig. 2, and includes a U-shaped frame 100 and a baffle plate 102 located in the frame, the baffle plate 102 is provided with a plurality of through holes to prevent the baffle plate 102 from blocking the view of the driver, and the baffle plate 102 is welded and fixed to the frame 100. The lifting device 20 may be an electro-hydraulic ram, a lead screw lift, a screw-type lifting mechanism, or the like. In order to ensure the stability of the goods shelf body 10 during the lifting process, the forklift goods shelf in this embodiment includes two lifting devices 20, the two lifting devices 20 are respectively and fixedly mounted on two sides of the fork frame 30 of the forklift in the width direction, and two sides of the goods shelf body 10 in the width direction are respectively and fixedly connected with one lifting rod 200.

Specifically, referring to fig. 1 to 3, in this embodiment, from the viewpoint of cost, a screw-type lifting mechanism is used, and the screw-type lifting device 20 includes a screw rod pipe 210, a screw rod body 200' as the lifting rod 200, and a driving member 220, the screw rod pipe 210 is fixed to the fork frame 30 of the forklift, the screw rod pipe 210 is a hollow pipe body, and an upper end portion thereof is a sealing end surface 2100 having a screw hole 2102 therein. The outer peripheral wall of the threaded rod body 200 ' is provided with an external thread, the external thread of the threaded rod body 200 ' is matched with the internal thread of the screw hole 2102, so that the threaded rod body 200 ' is directly screwed on the threaded rod pipe 210, the lower end part of the threaded rod body extends into the threaded rod pipe 210, the driving piece 220 is respectively in driving connection with the two threaded rod bodies 200 ' through the two bevel gear pairs 230, the threaded rod body 200 ' is driven to extend out or retract from the threaded rod pipe 210, and therefore the goods blocking frame body 10 is driven to do telescopic motion relative to the ground, and the height of the goods blocking frame body 10 is adjusted.

Preferably, in order to achieve synchronous adjustment of the two lifting devices 20 so as to maintain the adjustment of the height level of the retaining rack body 10, the two lifting devices 20 are synchronously adjusted by a synchronous rod 240. Specifically, referring to fig. 1 to 4, the bevel gear pair 230 includes a first bevel gear 2300 and a second bevel gear 2310 that are matched with each other, the first bevel gears 2300 on the two lifting devices 20 are respectively and fixedly mounted on opposite sides of the synchronization rod 240, and two ends of the synchronization rod 240 are supported on the frame 100 of the goods shelves body 10, the second bevel gears 2310 on the two lifting devices 20 are respectively and fixedly mounted on upper end portions of the two threaded rod bodies 200 ', the bevel teeth of the first bevel gear 2300 and the second bevel gear 2310 on the same bevel gear pair 230 are vertically arranged to convert horizontal rotation of the synchronization rod 240 into rotation of the threaded rod bodies 200' in a vertical direction, and the driving member 220 drives the synchronization rod 240 to rotate, so as to adjust the height of the goods shelves body 10.

The driving member 220 may be a stepping motor to automatically adjust the height of the shelf body 10. However, in view of cost, the driving member 220 of the present embodiment is preferably a manually adjustable crank. Specifically, a crank is mounted on an end portion of one side of the synchronization lever 240, and the height of the shelf body 10 is adjusted by manually rotating the crank. Preferably, the crank is detachably mounted on the synchronization rod 240, and after the height of the fender rack body 10 is adjusted, the crank can be removed to prevent the crank from colliding with a foreign object to cause a danger. The crank in this embodiment includes a sleeve having a non-circularly disposed cavity therein, and a handle secured to the sleeve. The end of one end of the synchronizing rod 240 is a non-circular structure matched with the cavity of the sleeve, when the height of the shelf body 10 needs to be adjusted, the sleeve of the crank is sleeved on the non-circular structure at the end of the synchronizing rod 240 to drive the synchronizing rod 240 to rotate, and after the adjustment is completed, the crank is directly taken down.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
