Abstract
This utility model discloses a limit protection mechanism using in mechanism project comprises a machine body having a door cover which pin joint to the machine body, a guide rail is set on the machine body along the direction of opening door, the guide rail is fixed to the machine body, the end of pin joint seat and the door cover which is neared by the guide rail has a gap, the medial surface of the door cover has a slide rod whose one end links to the door cover and the other end covers over the guide rail. The slide rod slides to the gap of the end of the guide rail along the guide rail when the door cover is open; the slide rod is locked automatically so as to avoid the accidents such as the blowing and the colliding which leads to the situation of closing the door cover.
Description
Technical field
The utility model relates to a kind of engineering machinery position limitation protection mechanism.
Background technology
The maintenance personal need open door closure on the machine with the inside near machine, for preventing that these door closures are closed by unexpected factor affecting such as wind, collision and needed stopping means usually when engineering machinery was safeguarded.The stopping means of existing engineering machinery exists structure complicated, the shortcoming that reliability is not high.
The utility model content
Technical problem to be solved in the utility model is that existing machine body door closure is subject to unexpected factor affecting such as wind, collision when opening and the problem of closing, and a kind of engineering machinery simple in structure, good reliability position limitation protection mechanism is provided.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise body, body is provided with door closure, door closure is articulated on the body, the body upper edge direction of opening the door is provided with a guide rail, guide rail is fixedlyed connected with body, the medial surface of door closure is provided with sliding bar, and an end of sliding bar links on door closure, and the other end is sleeved on the guide rail.
Above-mentioned engineering machinery is with in the position limitation protection mechanism, and described guide rail is provided with breach near the termination of door closure and body pivoting support.
The utility model has the advantages that: sliding bar slided into the breach of guide rail termination along guide rail when door closure was opened in the utility model, automatically locked sliding bar, and the situation of closing door closure like this with regard to having avoided unexpected factor affecting such as wind, collision takes place.The utility model is simple in structure, reliably good simultaneously.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model middle guide.
The specific embodiment
Referring to Fig. 1, the utility model is by body 1, guide rail 2, sliding bar 3, sliding bar pivoting support 4, door closure 5, hinge 7 is formed, body 1 is provided with door closure 5, door closure 5 is articulated on the body 1 by hinge 7, the body 1 upper edge direction of opening the door is provided with a guide rail 2, guide rail 2 is fixedlyed connected with body 1, the medial surface of door closure 5 is provided with sliding bar 3, sliding bar 3 is a stock, respectively there is a vertical minor axis at two ends, one end minor axis of sliding bar 3 links on door closure 5 through sliding bar pivoting support 4, and can be around this minor axis rotational, and the other end of sliding bar is taken on the guide rail 2 and can be slided on guide rail slide plane 8.As shown in Figure 2, the one side that guide rail contacts with sliding bar is set to smooth guide rail slide plane, and the termination of guide rail is provided with breach 6.
During use, open door closure 5, because the effect of gravity can be fallen down locking in this breach 6, sliding bar 3 can not do relative motion with guide rail 2 and became a stopping means sliding bar 3 this moment when guide rail 2 moves to guide rail 2 and do not hold, thereby the accident that prevents door closure 5 is closed.When closing door closure 5, needs only need not end with sliding bar 3 be raised up to the guide pass height and rotate door closure 3 to make sliding bar 3 touch the guide rail slide plane to get final product.
Claims (2)
1, a kind of engineering machinery position limitation protection mechanism; body is provided with door closure; door closure is articulated on the body; it is characterized in that: the body upper edge direction of opening the door is provided with a guide rail; guide rail is fixedlyed connected with body; the medial surface of door closure is provided with sliding bar, and an end of sliding bar links on door closure, and the other end is sleeved on the guide rail.
2, engineering machinery according to claim 1 position limitation protection mechanism is characterized in that: described guide rail is provided with breach near the termination of door closure and body pivoting support.
