Anti-falling folding engineering cart

Abstract

The invention discloses an anti-falling folding type engineering cart. The cart comprises a goods conveying plat. A transmission cavity which is through front and back portions is formed in the goodsconveying plate; a screw rod is arranged in the left side in the transmission cavity in an up-down sliding manner; a threaded cylinder is in sliding connection with the outer thread of the screw rod;the lower end of the threaded cylinder is rotatably connected with the inner wall of the lower side of the transmission cavity; a large gear is fixedly connected to the periphery of the lower end of the threaded cylinder; a left rotating rod is arranged on the right side of the threaded cylinder; and the lower end of the left rotating rod is rotatably connected with the inner wall of the lower side of the transmission cavity. When small scattered goods are transported, the goods can be prevented from falling off from the cart; when stacked box-type goods are transported, the goods can be prevented from collapsing and falling off during turning, the whole cart can be folded when the cart is not used, and an occupied space is saved; and compared with other anti-falling carts, the cart body is smaller and more flexible, and the flexibility of the cart is not sacrificed.

Description

technical field [0001] The invention relates to the field of engineering carts, in particular to a drop-proof folding engineering cart. Background technique [0002] Warehouse trolleys are often used to carry bulk goods in daily life. They are light and flexible. The disadvantage of existing common warehouse trolleys is that the goods are easy to drop, and when handling stacked box goods, it is easy to bump the goods slightly. Collapse, a kind of anti-drop folding engineering cart set forth in the present invention can solve the above-mentioned problems. Contents of the invention [0003] This example designs a kind of anti-drop folding engineering trolley. The anti-falling folding engineering trolley of this example includes a delivery board, and a transmission cavity through which the front and back are opened in the delivery board. There is a screw that slides up and down on the left side of the transmission chamber, and the external thread of the screw is slidingly co...
