Abstract
The utility model relates to a movable rear lower portion guard apparatus which belongs to a rear lower portion guard apparatus for a motor truck. A lower guard rail 1 is fixedly connected with a rotating rod 2 rotationally connected with a mounting plate 3 through a hinge 4. One end of an extension spring 6 is fixedly connected with the mounting plate 3, and the other end is fixedly connected with the rotating rod 2. One end where the rotating rod 2 is fixedly connected with the hinge is fixedly connected with a spacing block 5. The utility model has the advantages that the structure is novel, the usage is convenient, the utility model avoids the phenomenon that when the motor truck runs downwards or runs downwards along steps, a rear guard rail and the ground or objects on the ground collide, the utility model prevents an accident from happening and the utility model ensures the safety travel of the motor truck.
Description
Technical field
The utility model belongs to the defensive device of goods carrying vehicle rear lower.
Background technology
At present, in order to prevent that car from large-scale goods carrying vehicle generation rear-end collision the time, creeping into the lorry back, require the afterbody of goods carrying vehicle to add and load guard rail, its structure adopts stationary structure basically, promptly is the mode of being rigidly connected between this time guard rail and the car chassis.Since in the national standard strict regulations time guard rail terrain clearance, so the position of this fixed type guard rail always places in the automobile departure angle, shortcoming is, lorry travel at descending or be easy to when getting out of a predicament or an embarrassing situation with ground or on it object collide, thereby accident appears.
Summary of the invention
The utility model provides a kind of movable rear lower protective device, to solve because the lorry that causes for the mode of being rigidly connected between time guard rail and the car chassis travels at descending or when getting out of a predicament or an embarrassing situation and ground or on it object collide, thereby the problem of accident appears.The technical scheme that the utility model is taked is: following guard rail 1 is captiveed joint with dwang 2, this dwang 2 is rotationally connected by hinge 4 and adapter plate 3, one end of extension spring 6 is captiveed joint with adapter plate 3, the other end is captiveed joint with dwang 2, captives joint an end captive joint limiting stopper 5 with hinge at dwang 2.Adapter plate 3 can adopt split type or Contiuum type.During use, adapter plate is fixedly connected on truck chassis left-right longeron tail end place, deadweight produces torque to hinge axis by guard rail at ordinary times, closed contact between dwang and the adapter plate, when if obstacle is collided on following guard rail and the ground, following guard rail and dwang make down guard rail rotate avoiding barrier along the direction of raising around hinge axis.After having crossed obstacle, be returned to original position by the deadweight and the pulling force of extension spring.If automobile need fall back and travel when needing avoiding barrier, so the protection breast board is got up, following guard rail leans on the elastic force of crossing the extension spring that rotates the dead point, and can not fall voluntarily.
Advantage of the present utility model is: novel structure, easy to use, avoided lorry to travel at descending or when getting out of a predicament or an embarrassing situation rear portion guard rail and ground or on it object collide, prevented the generation of accident, guaranteed vehicle safe driving.
