Furthermore, the terms "mounted," "disposed," "provided," "connected," and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
The utility model provides a heavy quick detach fender structure of machine of wheeled has increased quick detach device 2 on original design basis, makes the fender can realize quick assembly disassembly under the condition with the help of not the instrument. The overall structure form figure is as shown in fig. 1, and the fender mainly comprises a fixed rod 1, a quick-release device 2 and a fender 3, and compared with the original structure form, the fender 3 can be quickly disassembled and assembled by adding the quick-release device 2. The main connection mode is the same as the original structure, the fixed rod 1 is fixedly connected with the axle through a bolt, and the quick-release device 2 is connected with the mudguard 3 through a bolt.
The specific structure of the quick release device 2 is shown in fig. 2, and the device mainly comprises a tension pressing sheet 21, a cotter pin 22, a screw 23, a buckle 24, a pin shaft 25 and a mounting base 26. The fender 3 is connected with a mounting base 26 through a bolt, the tensioning pressing sheet 21 is hinged with the mounting base 26 through a pin shaft 25, the tensioning pressing sheet 21 can rotate around the axis of the pin shaft 25, and the opening pin 22 is inserted into a pin hole of the pin shaft 25 to prevent the pin shaft 25 from axially jumping out. The hasp 24 is connected with the mounting base 26 through the screw 23, and during normal mounting, the hasp 24 enables the fixing rod 1 to be tightly pressed with the mounting base 26 through tightening the pressing sheet 21, so that the fixing rod 1 and the mounting base 26 are connected.
The other end of the tension pressing sheet 21 is bent upward smoothly to form a mounting buckle position 27 which is matched and buckled with the buckle 24.
Two lugs 28 are oppositely arranged on the mounting base 26, two opposite shaft holes are respectively arranged on the two lugs 28, a through hole is arranged on the tensioning pressing sheet 21, and the tensioning pressing sheet 21 is hinged on the mounting base 26 through a pin shaft 25 penetrating through the shaft holes and the through hole.
When the fender 3 is detached, the buckle 24 is firstly opened, the tensioning pressing piece 21 is unscrewed, the pressing force between the fixing rod 1 and the mounting base 26 is released, and the fender 3 is directly detached from the fixing rod 1, so that the quick-detaching function is realized. When the splash guard 3 is installed, the splash guard 3 with the installation base 26 thereon is placed below the fixing rod 1, the tensioning pressing sheet 21 is pressed on the fixing rod 1, and the installation base 26 and the fixing rod 1 are pressed through the hasp 24, so that the splash guard 3 can be installed quickly without the aid of tools.
