Abstract

The invention relates to the technical field of parking brake devices, and discloses a parking self-locking device for a transport trolley, which includes a first support rod and a second support rod slidably set on the first support rod, and the top end of the second support rod is connected to the first support rod. The bottom plate of the trolley body is fixedly connected; the side of the first support bar is provided with a first through hole, the first rotating shaft is in clearance fit with the first through hole, the supporting plate is respectively hinged with the two ends of the first rotating shaft, and the rear side of the supporting plate is welded with a buckle the steel bar; the side of the second support rod is provided with a second through hole, the second rotating shaft is in clearance fit with the second through hole, and the two ends of the second rotating shaft are respectively hinged with connecting plates; the supporting plate and the connecting plate are rotated through the third rotating shaft Connection; Relying on the force applied to the trip steel bar and the support plate, the two support rods move towards each other, and the locking surface on the support plate is locked and matched with the lower backing plate to realize the working state of the trolley and the locked state of parking, and can When the trolley is parked, the rollers are separated from the ground, which is beneficial to the protection of the rollers and the ground.

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.
