Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, specifically to a double-seat rear door of a dump truck with a protective device. Background Technology

[0002] Existing technologies for double-seat rear doors on dump trucks typically lack protective designs, often leading to the following problems in practical applications: During unloading, when the double-seat flap flips up, foreign objects such as stones can enter the bottom of the flap, causing the rear door to fail to close properly after unloading. Furthermore, in this state, the manual lock hook pin and the manual lock hook anti-jump plate are not on the same horizontal plane; closing the rear door will cause it to impact the manual lock hook anti-jump plate, potentially resulting in the manual lock hook pin breaking.
