Abstract

The invention relates to the technical field of parking braking devices, and discloses a self-lock device for carrying trolley parking. The self-lock device comprises a first supporting bar and a second supporting bar arranged on the first supporting bar in a sliding and sleeved mode. The top end of the second supporting bar is fixedly connected with a bottom plate of a trolley body. The side face of the first supporting bar is provided with a first through hole, a first rotating shaft is in clearance fit with the first through hole, supporting plates are hinged to the two ends of the first rotating shaft, and the back sides of the supporting plates are connected with tripping steel ribs in a welding mode. The side face of the second supporting bar is provided with a second through hole, a second rotating shaft is in clearance fit with the second through hole, and connecting plates are hinged to the two ends of the second rotating shaft respectively. The supporting plates are rotationally connected with the connecting plates through a third rotating shaft. The two supporting bars move in the reverse directions through the force exerted on the tripping steel ribs and the supporting plates, the trolley working state and the parking locking state are achieved through locking matching of locking faces of the supporting plates and a lower cushion plate, wheels can leave the ground when a trolley is parked, and the wheels and the ground can be protected.

Description

technical field [0001] The invention relates to the technical field of parking brake devices, in particular to a parking self-locking device for a transport trolley. Background technique [0002] The handling trolley is widely used in various production and assembly workshops. The bottom of the handling trolley is equipped with rollers to realize the movement of the trolley; when the trolley is stored, it needs to be fixed, such as figure 1 As shown, the existing technology usually relies on the brake clamp 2' on the roller 1' to block the roller to prevent it from rolling. This way, on the one hand, because the brake clamp 2' is mostly made of hard rubber material, it is easy to be deformed and damaged after long-term braking; There is a risk of damage to the ground. [0003] Therefore, those skilled in the art need to redesign the parking brake device of the transport trolley to facilitate the parking of the transport trolley and improve reliability.
