Technical Field
The utility model relates to a mechanism based on handle bidirectional rotation, which is used in the field of limit switches.
Background
In the existing limit switch, an operating rod can move up and down, and different signals can be respectively output in two moving directions. When the limit switch is combined with the existing operating handle, the limit switch can only generate the effect of enabling the operating rod to move in one direction, and the limit switch has larger use limitation.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides a mechanism based on bidirectional rotation of a handle, which can enable an operating rod to move in different directions and output different signals when the handle is rotated in two directions.
The technical scheme for achieving the purpose is as follows: a mechanism based on bidirectional rotation of a handle comprises a rotary handle, a rotating shaft and a trigger assembly;
the trigger assembly comprises a pressing block, a pressing block spring, a sliding block, an operation rod and an operation rod spring, wherein a step structure is arranged on the pressing block, the sliding block is abutted on the step structure, a connecting structure of the pressing block and the sliding block is sleeved outside the operation rod, the sliding block covers the top of the operation rod, the pressing block is connected with the pressing block spring, the operation rod is connected with the operation rod spring, and the pressing block spring and the operation rod spring are compressed by pretightening force;
the rotating handle is connected with the rotating shaft, and the rotation of the rotating shaft generates downward pressure on the trigger assembly; when the rotating shaft rotates to one side, the rotating shaft only generates downward pressure on one side of the step structure of the pressing block, so that the pressing block moves downwards, and at the moment, the sliding block and the operating rod are not stressed and move upwards under the action of the spring of the operating rod to form an upward signal; when the rotating shaft rotates to the other side, the rotating shaft generates downward pressure on one side of the sliding block on the pressing block, and drives the pressing block and the operating rod to move downwards together to form a downward signal.
Further, the outer sides of the rotating shaft and the triggering component are covered with a shell, and the rotating handle is inserted into one side of the shell and connected with the rotating shaft.
Still further, the shell passes through the screw and is connected with below switch body.
Further, a supporting table is arranged on the operating rod and supports the sliding block.
According to the mechanism based on the bidirectional rotation of the handle, when the handle rotates leftwards or rightwards, the corresponding operating rod moves upwards or downwards, so that bidirectional control operation is realized, and the application range of the handle operating limit switch is enlarged.

Detailed Description
In order to better understand the technical solution of the present utility model, the following detailed description is given by way of specific examples:
referring to fig. 1, the mechanism based on bidirectional rotation of a handle of the present utility model includes a rotary handle 1, a rotary shaft 2 and a trigger assembly.
The trigger assembly includes a press block 31, a press block spring, a slider 32, an operating lever 33, and an operating lever spring 34. The pressing block 31 is provided with a step structure, the sliding block 32 is abutted on the step structure, the connecting structure of the sliding block 32 and the step structure is sleeved outside the operating rod, the sliding block 32 covers the top of the operating rod 33, the operating rod 33 is provided with a supporting table, and the supporting table supports the sliding block 32. The pressing block 31 is connected with a pressing block spring, the operating rod 33 is connected with an operating rod spring 34, and the pressing block spring and the operating rod spring 34 are compressed by pretightening force.
The rotating handle 1 is connected with the rotating shaft 2, and the rotation of the rotating shaft 2 can generate downward pressure on the trigger assembly. The outer sides of the rotating shaft and the triggering component are covered with a shell, and the rotating handle is inserted into one side of the shell and connected with the rotating shaft. The shell is connected with the lower switch body through a screw.
Referring to fig. 2, when the rotating shaft rotates to the right, the rotating shaft only generates a downward force on one side of the step structure of the pressing block, so that the pressing block 31 moves downward, and at this time, the sliding block 32 and the operating rod 33 are not pressurized and move upward under the action of the operating rod spring 34, so as to form an upward signal.
Referring to fig. 3, when the rotating shaft 2 rotates to the left, the rotating shaft 2 generates a downward force on one side of the upper slider 32 of the pressing block, so as to drive the pressing block 31 and the operating rod 33 to move downward together, thereby forming a downward signal. When the rotating handle 1 is not forced, the whole structure is reset under the action of the pressing block spring and the operating rod spring.
The installation orientation of the sliding block and the pressing block is adjustable, so that the corresponding relation between the rotation of the rotating shaft and the movement of the operating rod is adjustable, and the signal direction triggered by the rotating handle is adjustable. The utility model expands the application range of the handle rotation limit switch, realizes the operation of bidirectional control (upward movement and downward movement) in actual use, and can also realize the function that only one side rotates to have signal output and the other side rotates to have no action.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
