Abstract
This utility model provides a travel switch rotating mechanism used for an explosion-proof switch, which comprises a travel switch and a rotating shaft, wherein one end of the rotating shaft is provided with a cam corresponding to the travel switch; and the other end corresponding to the rotating shaft is provided with a travel switch status mark. The travel switch rotating mechanism can be adopted for marking the work status of the travel switch on a panel of the explosion-proof switch clearly and reliably, meet the use conditions of the explosion-proof switch under a mine; and the travel switch rotating mechanism has the advantages of scientific design, simple panel, compact structure, convenient use, good security performance and high reliability.
Description
Technical field
The utility model relates to a kind of whirligig of flame-proof switch, specifically, has related to a kind of flame-proof switch travel switch rotating mechanism.
Background technology
At present, Chang Yong flame-proof switch is directly to control by the button spindle that is provided with on the shell with the travel switch using method; Button spindle is pressed, produced straight-line stroke, and then the control travel switch, make spring reset; But on the panel of flame-proof switch, the location status of button spindle is not obvious, and the sign difficulty easily produces potential safety hazard.
In order to overcome above problem, people are seeking a kind of technical solution always.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing flame-proof switch with difficult sign in the travel switch use, thereby a kind of design science, compact conformation, performance easy to use, safe flame-proof switch travel switch rotating mechanism good, that reliability is high are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of flame-proof switch travel switch rotating mechanism, comprise travel switch and rotating shaft, and described rotating shaft one end is equipped with cam, and described cam correspondence course switch is provided with; The corresponding rotation axle other end is provided with the travel switch state and indicates.
The utility model has substantive distinguishing features and progress with respect to prior art, specifically, adopts this mechanism, can identify the operating state of travel switch clear on the panel of flame-proof switch, reliably, satisfies the condition of using under the flame-proof switch coal mine; It has that design science, panel are succinct, compact conformation, performance easy to use, safe is good, reliability is high advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A-A of cam described in Fig. 1 is to the sectional structure schematic diagram.
Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of flame-proof switch travel switch rotating mechanism comprises travel switch 1 and rotating shaft, and described rotating shaft one end is equipped with cam 2, and described cam 2 foreign steamer walls contact with travel switch 1 to satisfy the purpose of cam 2 control travel switches 1; The corresponding described rotating shaft other end is provided with the travel switch state and indicates; Described rotating shaft is installed in the axle bed on the flame-proof switch shell wall, and described travel switch state indicates and is installed on the flame-proof switch shell wall panel; The shape of described cam designs according to the on off state needs of travel switch.
On the shell wall of explosion-resistant enclosure, rotating shaft is installed in the axle bed, and the operating state sign of panel upper stroke switch is clear; In inside, shell chamber, rotating shaft has a cam, and cam has the shaft shoulder, cam control one stroke switch, and have spacing on the cam.When needs travel switch transition status, the rotation rotating shaft, the cam of interior of rotating shaft produces rotation, and rotatablely moving of cam offers the travel switch rectilinear path, thus the control travel switch; Rotate rotating shaft, drive cam 1 rotation, generation rotatablely moves, and is converted to the impulse stroke that travel switch 2 needs; It is the stroke of limitation travel switch 2 that platform on the cam 1 provides stroke, cylindrical when rotating.
Claims (2)
1, a kind of flame-proof switch travel switch rotating mechanism comprises travel switch and rotating shaft, it is characterized in that: described rotating shaft one end is equipped with cam, and described cam correspondence course switch is provided with.
2, flame-proof switch according to claim 1 travel switch rotating mechanism is characterized in that: the corresponding described rotating shaft other end is provided with the travel switch state and indicates.
