Abstract

The utility model relates to the technical field of garbage disposal vehicles, in particular to a garbage can anti-falling device with a self-locking system, which comprises a guide mechanism, a can hanging mechanism for fixing a can body is movably arranged on the guide mechanism, and a can turning mechanism for turning the can body to pour materials after the can body is lifted is hinged to the can hanging mechanism. A self-locking mechanism for preventing the barrel body from falling off is fixedly arranged at the joint of the barrel overturning mechanism and the barrel hanging mechanism; the self-locking mechanism comprises a hinge block fixedly connected to the can hanging mechanism, and a self-locking hook is hinged to the hinge block. According to the garbage can anti-falling device with the self-locking system, if the can body swings back and forth when toppling over, the can body tends to turn over forwards at the moment, then a can hanging frame and a can pressing plate move relatively, but a fixing pin at the bottom of a pull rod tends to tension a self-locking hook backwards along a strip-shaped hole, and therefore the garbage can is prevented from falling off. And the hook part at the bottom of the self-locking hook can hook and lock the self-locking pin on the barrel hanging mechanism, so that self-locking is realized, and the barrel body can be prevented from falling off.

Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal vehicles, in particular to a garbage can anti-falling device with a self-locking system. Background Art

[0002] At present, the anti-falling device for trash cans includes a bucket pressing mechanism, a bucket hanging mechanism, a lower roller group and a first roller group. Rectangular tubes are arranged on both sides of the bucket hanging mechanism, a bucket hanging plate is arranged on the bucket hanging mechanism, and the lower roller group is installed on the rectangular tube of the bucket hanging mechanism through a fixed block. The bucket pressing mechanism includes a guide groove and a bucket pressing plate. The bucket pressing plate is installed on the upper part of the guide groove, and a waist-shaped groove is opened on the guide groove. The first roller group is installed on the upper part of the guide groove, and the lower roller group is installed in the waist-shaped groove on the guide groove. When the bucket is flipped at an angle greater than 45 degrees, the bucket hanging mechanism and the bucket pressing mechanism have no relative movement, which eliminates the safety hazard of the trash can falling to a certain extent. However, in actual use of the device, since the trash can will swing back and forth during the lifting and flipping process, the problem of relative movement between the bucket hanging mechanism and the bucket pressing mechanism will still occur when dumping garbage due to the trash can tipping forward. Therefore, the trash can is still easy to fall off when dumping. Utility Model Content
