The invention discloses a tail plate structure with an exhaust-free piston cylinder. The tail plate structure comprises a support frame, a force arm, an inclined plate, a lifting oil cylinder, a turning plate oil cylinder and a balance oil cylinder. The force arm is installed on the support frame, a crank arm connected with the inclined plate is arranged at the end of the force arm, the upper end of the crank arm is connected with the inclined plate, the lower end of the crank arm is connected with the lifting oil cylinder, and the turning plate oil cylinder is connected with the support frame and the inclined plate. The force arm, the turning plate oil cylinder and the lifting oil cylinder are installed through the support frame, the force arm is connected with the support frame and the inclined plate, the turning plate oil cylinder drives the inclined plate, the lifting oil cylinder drives the force arm to drive the inclined plate to be turned upwards and lifted and placed downwards for unloading, and the end of the inclined plate is provided with a certain inclination angle to be attached to the ground, so that cargo loading and unloading are more convenient and labor-saving; the balance oil cylinder balances the pressure of the turning plate oil cylinder and the pressure of the lifting oil cylinder, the effect of balancing the actions of the turning plate oil cylinder and the lifting oil cylinder is achieved, the turning plate oil cylinder and the lifting oil cylinder are provided with exhaust-free pistons, an exhaust structure does not need to be arranged, and the overall structure of the oil cylinder is simplified.
Description
technical field [0001] The invention relates to the field of logistics equipment, in particular to a tailgate structure with an exhaust-free piston cylinder. Background technique [0002] According to related technologies, the tail lift can improve the efficiency of loading and unloading. It is a hydraulic lifting device installed at the rear of a truck or other vehicles, which can save labor for loading or unloading goods. However, the hydraulic cylinder needs to be equipped with an exhaust and pressure relief circuit. , the structure is complex, therefore, in order to avoid the shortcomings in the prior art, it is necessary to improve the prior art. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a tailgate structure with an exhaust-free piston cylinder, which can work without exhausting, lift and lower the tailgate, and facilitate loa...
