The invention relates to an automatic locking mechanism for a rear door of a light dump truck. The automatic locking mechanism comprises a pull rod seat, a pull rod, a lock hook and a pin shaft arranged on the pull rod seat, wherein the pull rod seat is fixed to a frame below a compartment of the light dump truck, one end of the pull rod is fixed to the pin shaft, and the other end of the pull rod is connected with a thread fork, the lock hook comprises a lock hook main body and a lock hook head, wherein a fixing hole A and a fixing hole B are formed in the lock hook main body, the fixing hole A is fixedly connected with the thread fork, and the fixing hole B is fixed to the bottom of the compartment through a fixing shaft. The automatic locking mechanism for the rear door of the light dump truck disclosed by the invention has the benefits that the lock hook takes rear overturn as the center to carry out a circular motion along the compartment, meanwhile, the lock hook carries out the circular motion by taking the pull rod seat as the circle center and the pull rod as the radius, and further carries out an irregular turnover movement by bearing two circle center forces to be automatically opened or locked, and the thread fork and the pull rod can adjust tightness degree of the locking mechanism through the thread fork and the pull rod to improve the flexibility while opening or closing the rear door of the compartment.
Description
Technical field [0001] The invention belongs to the technical field of auxiliary equipment for dump trucks, and relates to an automatic locking mechanism, in particular to an automatic locking mechanism for a rear door of a light dump truck. Background technique [0002] With the reform of my country's urbanization and social system transformation, heavy-duty semi-trailer and full-trailer trucks can no longer meet the requirements of a variety of diversified transportation modes, and relatively flexible and more practical light-duty dump trucks usher in development opportunities. [0003] The operability, stability and safety of the rear door locking device of a light dump truck are important manifestations of the vehicle's functions. In the current market, the forms of the rear door locking structure during the transportation of dump trucks mainly include: traditional chain locking plate type and forced push rod type locking mechanism. The structure is single and unstable, which c...
