Embodiment Construction

[0032] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] This embodiment proposes an automatic locking mechanism for doors and windows of special vehicles, its structure is as follows: figure 1 and 2 As shown, it mainly includes electric cylinder support 1, electric cylinder pin 2, electric cylinder 3, connecting rod pin 4, cotter pin 5, rotating arm assembly 6, connecting rod 7, locking mechanism assembly 8, rotating arm Support 9 and locking base 10.

[0034] Electric cylinder support 1 and two boom supports 9 (such as image 3 shown) welded at the set position on the top deck of the door frame, and the two locking bases 10 are respectively welded to the set position on the door panel, and ensure the centerlines of the two pivoting arm supports 9 and the centerline...

Abstract

The invention provides an automatic locking mechanism for special vehicle doors and windows. An electric cylinder is used as a power source, rotating arms are driven by connecting rods to rotate around supports, two rotating arm mechanisms are driven to rotate, and locking and unlocking of the two locking points and locking mechanisms are achieved. The connecting rods move along a straight line, and the rotating arms are driven to rotate around the rotating arm supports through the movement of the connecting rods, sleeves are designed at the matched parts of the rotating arms and locking structures so as to reduce resistance in the movement process, the connecting rods and the electric cylinder as well as the connecting rods and the rotating arms are connected and fixed by pin shafts and cotter pins, and a joint bearing is designed at the end part of each connecting rod mechanism, so that resistance in the movement process is reduced. The connecting positions of the connecting rods, the rotating arms and the connecting rods are connected and fixed by the pin shafts and the cotter pins. Locking seats are designed to be of a wedge-shaped structure, and locking and sealing of a door and a window can be achieved through adjusting gaskets. In addition, an emergency opening structure under the power failure condition is designed, and the locking and unlocking functions under the automatic failure condition can be achieved by releasing a pin shaft at the fixed seat end of the electric cylinder.

Description

technical field [0001] The invention belongs to the technical field of special vehicles, and in particular relates to an automatic locking mechanism for doors and windows of special vehicles. Background technique [0002] Existing doors and windows of special vehicles are mostly bolt-type or ratchet-type collision lock structure, and most of them are in the form of a single lock point. When the size of the door and window is large or the thickness of the door panel is small, the door panel will warp and deform, and the part without the lock point will be sealed. Lack of tightness, poor airtightness and other issues. Even if a small number of locking points are used, they are all locked manually and need to be locked separately. The efficiency is low, especially the position of most lock tongues is sliding friction, which needs to overcome a large friction force. The effect is not achieved by applying grease. Not good, it takes time and effort to use, when closing the door a...
