Description

Technical Field

[0001] The utility model belongs to the technical field of flatbed trucks and relates to a flatbed truck with a cargo stabilizing mechanism. Background Art

[0002] When a truck is transporting goods, if the cargo compartment is not fully loaded, the goods in the cargo compartment will shift when the truck is driving on a bumpy road or turning, and the goods are easily damaged during the movement. Even more, when a truck is driving at high speed on a road, especially a highway, the center of mass of the truck will shift to the inside of the curve at the bend, and the cargo compartment will also tilt to the inside of the curve, causing the objects in the cargo compartment to move to the side of the cargo compartment corresponding to the inside of the curve, thereby aggravating the tilt of the center of mass of the truck to the side corresponding to the inside of the curve, thus causing the truck to overturn at the bend, causing a traffic accident;

[0003] In the prior art, there is a cargo compartment stabilizing mechanism that can stabilize cargo by reducing the cargo compartment space; for example, a Chinese patent discloses a cargo stabilizing device for a truck [application number: 201410727135.8], which includes a guide rail, two of which are respectively arranged on two side walls of the cargo compartment of the truck; a sliding plate, two of which are respectively arranged on the two guide rails in a manner that allows them to slide back and forth, and the two sliding plates are parallel to the side walls of the cargo compartment; a locking mechanism, which is used to lock the sliding plates to stay at any position on the guide rails; a cargo baffle, two of which are respectively pivotally connected to the front ends of the two sliding plates in a manner that allows them to swing back and forth; and a fixing mechanism, when the two cargo baffles are swung to a position perpendicular to the two sliding plates, the two cargo baffles are respectively fixed by the two fixing mechanisms;

[0004] However, multiple items cannot be placed completely close together in the cargo compartment. The cargo compartment stabilization mechanism cannot limit the position of the items placed in the middle, and the gaps between the items will cause the items to shake in the cargo compartment.

[0012] In the above-mentioned flatbed truck with a cargo stabilizing mechanism, a number of left and right limit plates corresponding to a number of front and rear limit plates are connected in a wave shape, the cross-section of the left and right limit plates is an isosceles trapezoid, the outward ends of the left and right limit plates are vertical surfaces, and the tops of the inward ends of the left and right limit plates have inclined limit surfaces.

[0013] In the above-mentioned flatbed truck with a cargo stabilization mechanism, the No. 2 lifting assembly includes two No. 2 lifting drives symmetrically arranged on the lower side of the vertical slide groove, the output shaft end of the No. 2 lifting drive is fixedly connected to the bottom of the left and right limit plates, and two No. 2 limit rods are symmetrically arranged at the bottom of the left and right limit plates, and the No. 2 limit rods are inserted into the front and rear limit plates and slidably cooperate with the front and rear limit plates.

[0014] In the above-mentioned flatbed truck with a cargo stabilizing mechanism, three sets of rebound-type stabilizing structures are also provided on the front and rear limit plates.

[0021] 3. Arranging a plurality of left and right limit plates along the length direction of the cargo chassis in a wave shape can adjust the width of the cargo placement area separated by two left and right limit plates. For cargoes of different widths, the left and right limit plates on different front and rear limit plates are used for limiting.

[0022] 4. After the front and rear limit plates with goods placed on them sink, there may be a gap between the front and rear limit plates adjacent to the goods and the goods. The gap can be filled by the rebound stabilizing structure to prevent the goods from shaking due to the gap. The spring on the horizontal limit rod can exert an outward thrust on the elastic limit plate to make the elastic limit plate and the goods offset each other, filling the gap that may exist between the front and rear limit plates and the goods. The horizontal limit rod can limit the elastic limit plate. The guide surface at the bottom of the elastic limit plate can offset the adjacent front and rear limit plates when the front and rear limit plates sink, and can exert a force on the elastic limit plate to move into the horizontal slide groove.
