The invention discloses a telescopic pallet fork, and relates to the technical field of storage. The telescopic pallet fork comprises a lower fork plate, a middle fork plate, an upper fork plate, a first chain, a second chain and a third chain, the middle fork plate is provided with hanging lugs, and the hanging lugs are in engagement with the first chain. One end of the second chain penetrates through the middle fork plate and is fixed to the end, connected with the middle fork plate, of the upper fork plate, and the other end of the second chain is fixed to the end, away from the middle forkplate, of the lower fork plate. One end of a third chain penetrates through the middle fork plate and is fixed to the end, away from the middle fork plate, of the upper fork plate, and the other endof the third chain is fixed to the end, connected with the middle fork plate, of the lower fork plate. When the pallet fork needs to extend, the first chain rotates reversely, and the hanging lug drives the middle fork plate to move in the direction away from the lower fork plate. When the pallet fork needs to be contracted, the first chain rotates in the forward direction, and the hanging lugs drive the middle fork plate to move in the direction opposite to the lower fork plate.
本发明公开了一种可伸缩货叉,涉及仓储技术领域,包括下叉板、中叉板、上叉板、第一链条、第二链条以及第三链条,所述中叉板设有挂耳,所述挂耳与第一链条啮合;所述第二链条的一端穿过中叉板并固定在上叉板与中叉板连接的一端,所述第二链条的另一端固定在下叉板远离中叉板的一端;所述第三链条的一端穿过中叉板并固定在上叉板远离中叉板的一端,另一端固定在下叉板与中叉板连接的一端。当货叉需要伸长时,第一链条反向转动,使挂耳带动中叉板向着与下叉板相离的方向运动;当货叉需要收缩时,第一链条正向转动,使挂耳带动中叉板向着与下叉板相向的方向运动。
