Lifting longitudinal capturing mechanism for opening and closing truck bucket shield

Abstract

The invention provides a lifting longitudinal capturing mechanism for opening and closing a truck bucket shield. The lifting longitudinal capturing mechanism is applied to a truck. The truck is provided with a bucket and a swing arm in a square n shape. Free ends are formed at the two ends of the swing arm. A pivot is fixedly arranged between the positions, below the bucket, of the two free ends. The lifting longitudinal capturing mechanism comprises a shield net raising device and a shield net downward-pressing and covering device. The shield net raising device comprises a first elastic element, one end of the first elastic element is combined to the bottom side of the bucket, and the other end of the first elastic element is combined to an arm rod. A first distance is formed at the position, connected with the shield net raising device and the pivot, of the arm rod. The shield net downward-pressing and covering device comprises a second elastic element, one end of the second elastic element is combined to the bottom side of the bucket, a swing piece is connected with the second elastic element, and a second distance is formed between the connecting position of the swing piece and the second elastic element and the center of the pivot.

Description

technical field [0001] The invention is applied to the technical field of truck equipment, in particular to an elevating escapement mechanism for opening and closing the truck body cover that can effectively and stably open and close the truck body cover. Background technique [0002] At present, in order to improve the safety of the truck and the positioning effect of the goods, such as sand or goods, it is necessary to install a layer of cover on the body of the truck when the truck is running to prevent the sand or goods from flying out, but generally It is known that the opening and closing of the cover of the truck body is mostly rotated by a ㄇ-shaped swing arm pivoted on the periphery of the truck, and cooperates with the linkage of an elevating and retracting mechanism and an elevating mechanism to link the opening or setting of the cover. Among them, the lifting mechanism mainly uses the spring to directly pull the arm bar, and cooperates with the lifting and retract...

Problems solved by technology

[0004] In view of the actual use of the lifting mechanism for the opening and closing of the known truck body cover, there are still problems that the cover cannot effectively and stably cover the vehicle body and cause the service life of the lifting and retracting mechanism to be poor. The purpose of the present invention is to Provides a lifting escapement mechanism for the opening and closing of the cover of the truck body, which can stably and effectively open the cover or cover the vehicle body under strong wind force, overcome the situation of sailing when the cover occurs, and at the same time reduce the number of trucks.
