As an improvement of the invention, the horizontal direction outside of the panel and the vertical direction top are provided with a limit groove, the door handle is L-shaped formed by steel pipe rings, and the free end of the door handle is clamped in the limit groove.
As an improvement of the invention, the size of the inlet of the limiting groove is less than or equal to the diameter of the steel pipe.
As an improvement of the invention, the arc-shaped plate is a spring steel plate.
As a modification of the invention, the cross section of the catch plate is shuttle-shaped.
As an improvement of the invention, the spring is arranged in the limiting pipe.
The invention has the beneficial effects that:
according to the side door locking device for the engineering truck operating room, the clamping plate can be locked by the spring plate through the revolving door handle, the revolving door handle cannot rebound upwards under the action of gravity, the structure is simple, the operation is convenient and safe to open and close, the manufacturing cost is low, and the application and popularization values are good.

Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in the figure, the side door locking device for the engineering vehicle operation room comprises a lock and a locking fixture block, wherein the lock comprises two panels 1 which are symmetrically arranged, the two panels are respectively matched with a door handle 2, mandrels 3 of the two door handles are connected, the mandrels are connected with a clamping plate 4, the locking fixture block comprises two fixing plates 5 which are symmetrically arranged, a vertical arc-shaped plate 6 is arranged on one fixing plate, a baffle 7 is arranged below the arc-shaped plate 6, a gentle slope 8 is arranged above the arc-shaped plate 6, an abrupt slope 9 is arranged below the arc-shaped plate 1/3, the joint of the gentle slope 8 and the abrupt slope 9 props against the other fixing plate, a spring 10 is arranged in an inner cavity of the arc-shaped plate 6, the lower end of the arc-shaped plate is connected below the spring 10, and the clamping plate 4 is clamped between the abrupt slope 9 and the baffle 7.
According to the side door locking device for the engineering vehicle operation room, the clamping plate 4 is arranged in the 45-degree direction of the side face of the mandrel 3, the lockset is arranged on an engineering vehicle door, the locking fixture block is arranged in a door frame, the door handle 2 is rotated (from the horizontal direction to the vertical direction, as shown in the figure 1), the mandrel 3 drives the clamping plate 4 to press downwards, the clamping plate 4 penetrates through the arc-shaped plate 6 and is arranged between the abrupt slope 9 and the baffle 7, the switch is flexible, 2/3 above the arc-shaped plate 6 is a gentle slope 8, when the clamping plate 4 enters the position, a gap is opened between the arc-shaped plate 6 and another fixing plate (the lower end of the arc-shaped plate 6 moves downwards under the action of the spring 10), and the clamping plate penetrates through the gap and smoothly enters between the abrupt slope 9 and the baffle 7; however, if the clamping plate 4 moves reversely, the abrupt slope 9 is arranged below the arc-shaped plate 1/3, and the clamping plate 4 is difficult to open a gap facing the abrupt slope 9 without external force, so the clamping plate 4 is stably arranged between the abrupt slope 9 and the baffle 7; the direction of the clamping plate 4 is inclined downwards, and the clamping plate cannot rebound upwards under the action of gravity, so that the side door of the engineering vehicle operating room is stable once being closed, and when the door needs to be opened, the door handle 2 is rotated from the vertical direction to the horizontal direction.
The invention is characterized in that a limiting groove 11 is arranged on the outer side of the panel 1 in the horizontal direction and above the panel in the vertical direction, as shown in figure 1, the door handle 2 is L-shaped formed by steel pipe coils, as shown in figure 2, the free end of the door handle 2 is clamped in the limiting groove 11 (the door handle 2 is fixed by adopting a structure of interference fit or spring clamping balls), and the false action is avoided when the engineering truck vibrates violently.
If interference fit is adopted, the size of the inlet of the limiting groove 11 is smaller than or equal to the diameter of the steel pipe, the door handle is held by a hand when the door handle 2 is rotated, the tail end of the door handle 2 is bent into an L shape, and the tail end of the door handle 2 is clamped into the limiting groove 11 when the door handle is in place.
The arc-shaped plate 6 is a spring steel plate and has certain elasticity, and resistance is reduced when the clamping plate 4 enters or exits the arc-shaped plate.
The cross section of the clamping plate 4 is shuttle-shaped, and the resistance can be reduced when the clamping plate enters and exits the arc-shaped plate.
The spring 10 is vertically arranged in the limiting pipe 12, so that the lower end of the arc-shaped plate can only move up and down, and cannot deform due to left and right twisting.
