Locking mechanism used on tractor hood and having automatic centering function

Abstract

The invention discloses a locking mechanism used on a tractor hood and having an automatic centering function. The locking mechanism comprises a hood body, locking mechanism bodies and a centering mechanism. The hood body is arranged at the end of a tractor and comprises a top cover and a hood body, the top cover is located over the hood body, and the top cover is connected with the hood body through the locking mechanism bodies. The locking mechanism bodies are located on the two sides of the hood body, each locking mechanism body comprises a first locking piece and a second locking piece, wherein the first locking piece is installed on the side wall of the top cover, the first locking piece is of an L-shaped structure, the second locking piece is installed on the side wall of the hood body, the second locking piece is located under the first locking pieces, and the second locking piece is matched with the first locking piece. According to the locking mechanism, the tractor hood can be conveniently mounted and dismounted; and the safety when the tractor hood is assembled and disassembled is ensured.

Description

technical field [0001] The invention belongs to the technical field of tractors and relates to a locking mechanism, in particular to a locking mechanism which is used on a tractor hood and has an automatic centering function. Background technique [0002] Tractor is a kind of common mechanical equipment, and it can be provided with a tractor hood usually to protect engine, when people need to maintain the engine that is installed in the tractor hood, often need to open tractor hood. [0003] Reference document CN2936881 discloses an opening and locking device for a tractor hood, which includes a limiting plate fixed to the front end of the side of the tractor frame, a locking plate rotatably connected to the limiting plate, and a tractor hood A fixedly connected lock column; the upper part of the lock plate is provided with a first open groove extending in the transverse direction, and when the lock plate rotates, it has a locking position where the lock column snaps into th...

Problems solved by technology

[0005] The purpose of the present invention is to solve the existing tractor hood, one end of which is hingedly connected with the tractor frame, and the other end is connected with the tractor frame through threads, so that when the tractor hood is opened, frequent tightening and loosening are required. Screws, such a structure is not only inconvenient to operate, but also easy to damage the threads after long-term use, resulting in the inability to lock the tractor hood in the end, which seriously affects the normal use of the tractor hood. When the tractor hood is removed, the casing or The temperature of the operating position is too high, which affects the normal disassembly, and even the problem of burns due to poor protection. A locking mechanism with automatic centering function for the tractor hood is proposed
