Description

Technical Field

[0001] The utility model relates to the field of vehicle accessories, in particular to a quick disassembly and assembly fastening device and a vehicle. Background Art

[0002] In the design of commercial vehicles, vehicle structure plays a vital role. Especially in those scenarios with harsh operating environments and complex road conditions, commercial vehicles face more severe challenges. When a vehicle is driving on an uneven road, gravel, sand and other debris on the road surface are often picked up by the wheels or splashed by the vibration of the road surface. These splashed debris are very likely to collide with key components on the frame, such as the engine, drive shaft, water tank, etc., posing a potential threat to the normal operation of the vehicle.

[0003] To deal with this problem, designers usually install various covering panels on the vehicle frame. These panels can not only effectively block flying debris and protect key vehicle components from damage, but also improve the appearance of the vehicle to a certain extent. However, the installation of the panels is not easy. In order to ensure that the panels can be firmly fixed on the frame, it is necessary to accurately open the corresponding threaded holes on the frame and tightly connect the panels to the frame with bolts.

[0004] However, when the vehicle is being inspected, these panels covering the vehicle components become obstacles. In order to expose the inspection object, the inspection personnel have to remove these panels. This means that they need to remove the bolts one by one and reinstall them after the inspection is completed. Since commercial vehicles are subject to various vibrations during driving, in order to ensure the stability of the panel, the bolts are usually tightened to a certain tightening torque. This causes a large mutual pressure between the threads. However, this fastening method also brings a problem that cannot be ignored-thread wear and deformation. With the repeated disassembly and assembly of the bolts, the wear of the threads will gradually increase, and even slippage will occur. This will not only lead to the failure of the panel mounting structure, but also may cause a serious hidden danger of panel falling off. Summary of the invention

The bracket plate is connected to the frame, and the hole position can be extended to a position that is convenient for operation through the shape design of the bracket plate, and the operation frequency of the frame hole position can be further reduced.

[0010] Preferably, a stopper is provided at the edge of the bracket plate, and the connecting plate between the first plate body and the second plate body is located in the stopper, so that the second locking member is more stably connected and prevents shaking.

[0011] Preferably, the first section of the locking rod is also provided with a hand-tightening structure, which makes the operation more convenient.

[0012] Preferably, the hand-tightening structure comprises a U-shaped rod, two ends of the U-shaped rod are oppositely provided with connecting posts, the outer periphery of the baffle is provided with connecting holes, and the connecting posts are inserted into the connecting holes.
