Door locking mechanism for garbage transfer box

Abstract

The invention relates to a door locking mechanism, in particular to a door locking mechanism for a garbage transfer box, which comprises a box body (10) and an upper door plate (20), guide rails (11) are arranged at the two ends of the upper side of the box body (10), and the upper door plate (20) is clamped in the guide rails (11) and can slide along the guide rails (11). The door locking mechanism is further provided with a telescopic hinge (30) and a hydraulic cylinder (40), a hinged base (12) is arranged at one end of the box body (10) away from a feeding port, the cylinder head of the hydraulic cylinder (40) is hinged with the base (12), a piston rod of the hydraulic cylinder (40) is hinged with the telescopic hinge (30), and one end of the telescopic hinge (30) is connected with the upper door plate (20). The door locking mechanism has the benefits that the upper door plate is horizontally pushed in a way that the hydraulic cylinder is matched with the telescopic hinge to further open and close the feeding port, a larger opening space is realized by a smaller space, and the door plate can be reliably locked.

Description

technical field [0001] The invention relates to a door locking mechanism, which is especially suitable for the door locking structure of a garbage transfer box. Background technique [0002] The garbage station transfer box is a kind of garbage storage and transportation equipment used for urban concentration, storage of domestic garbage, and transfer to garbage treatment plants by vehicles such as vehicles. A door body is installed at the feeding port of the garbage truck. When dumping garbage into the garbage bin, the garbage transfer box automatically opens the door, and automatically closes the door body after dumping. The structures commonly used in the prior art are as figure 1 and figure 2 As shown, a switch mechanism 1-1 is installed on the fixed frame 1, and the switch mechanism 1-1 includes a connecting rod mechanism and a hydraulic cylinder, figure 2 It is a partial enlarged view of A. It can be seen that the hook of the switch mechanism 1-1 linkage mechanism...

AI Technical Summary

Problems solved by technology

[0006] 3. When the switch mechanism 1-1 is docked with the upper door panel 2-1 of the box, if figure 2 As shown, the hook needs to be completely hooked to the card slot on the upper door panel, which requires the operator to be very careful. If the connection is not complete, the operator needs to manually connect it, which not only increases the workload, but also has certain dangers.
