Description
Technical Field
The utility model relates to the technical field of station stoppers, in particular to a mechanical blocking structure.
Background
In an industrial production line, when a tray reaches a station, a stopper is required to block the tray; in the prior art, the stopper often uses pneumatics or electronic as the power supply, for this production line need dispose extra power device and transmission structure, has increased the construction cost and the running cost of production line, simultaneously because the structure is complicated breaks down easily, has reduced the stability of production line operation.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects in the prior art, the utility model provides a mechanical blocking structure which can realize the cargo blocking function through a mechanical structure without an additional power source.
The technical scheme is as follows: in order to achieve the purpose, the mechanical blocking structure comprises a blocking pin, a mounting seat, a first connecting rod, a second connecting rod, a third connecting rod, an optical axis and a stress plate; the stop pin is inserted into the mounting seat along the vertical direction, a convex rod is arranged at the bottom end of the stop pin, and the convex rod is exposed from a sliding groove at the side of the mounting seat; one end of the second connecting rod is rotatably connected to the convex rod, and the other end of the second connecting rod is rotatably connected to a first shaft end of the third connecting rod; one end of the first connecting rod is rotatably connected with a fixed rod on the side of the mounting seat, the fixed rod and the convex rod are positioned on the same straight line in the vertical direction, and the fixed rod and the convex rod are connected and provided with tension springs; the other end of the first connecting rod is rotatably connected to the first shaft end; and the second shaft end of the third connecting rod is rotatably connected to one end of the optical axis, and the other end of the optical axis is connected to the stress plate.
Furthermore, an upper mounting plate is arranged at the top of the mounting seat and connected to the station surface.
Further, a linear bearing is arranged on the periphery of the optical axis.
Has the advantages that: the mechanical blocking structure can realize the cargo blocking function through the mechanical structure without an additional power source, and comprises the following technical effects:

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figures 1-3: a mechanical blocking structure comprises a blocking pin 1, a mounting seat 2, a first connecting rod 31, a second connecting rod 32, a third connecting rod 33, an optical axis 4 and a stress plate 5; the blocking pin 1 is inserted into the mounting base 2 along the vertical direction, a convex rod 11 is arranged at the bottom end of the blocking pin 1, and the convex rod 11 is exposed from a sliding groove on the side of the mounting base 2; one end of the second link 32 is rotatably connected to the protruding rod 11, and the other end of the second link 32 is rotatably connected to the first shaft end 331 of the third link 33; one end of the first connecting rod 31 is rotatably connected to a fixing rod 21 on the side of the mounting base 2, the fixing rod 21 and the protruding rod 11 are located on the same straight line in the vertical direction, and the fixing rod 21 and the protruding rod 11 are connected and provided with a tension spring 111; the other end of the first link 31 is rotatably connected to the first shaft end 331; the second shaft end 332 of the third link 33 is rotatably connected to one end of the optical axis 4, and the other end of the optical axis 4 is connected to the stress plate 5; under the state of no external force, the convex rod 11 is pulled upwards under the action of the tension spring 111, so that the blocking pin 1 is in an extending state, and a tray on a station is blocked; when the tray needs to be taken away, an external force is applied to the stress plate 5, the stress plate 5 pushes the second shaft end 332 of the third connecting rod 33 through the optical axis 4, the first shaft end 331 of the third connecting rod 33 acts on the first connecting rod 31 and the second connecting rod 32, and since one end of the first connecting rod 31 is fixedly connected to the fixing rod 21, one end of the second connecting rod 32 connected with the protruding rod 11 pushes the blocking pin 1 downwards and stretches the tension spring 111.
An upper mounting plate 22 is arranged at the top of the mounting base 2, and the upper mounting plate 22 is connected to a station surface 23; the mounting plate 22 can better fix the blocking structure, so that the blocking pin 1 can stably block the tray.
A linear bearing 41 is disposed around the optical axis 4.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the utility model and these are intended to be within the scope of the utility model.
