[0015] In order to make the utility model purposes, technical scheme and advantages more clearly, the following is combined with the embodiment, and the utility model is further detailed.The specific embodiments described herein are merely used to explain the utility model and not used to limit the utility model.

[0016] As Figs. 1-2 The utility model discloses a kind of fork piece emergency stop pull mechanism suitable for mine telephone, including device body 1, still including cable socket 2, the cable socket 2 is worn in the both sides of device body 1, and cable socket 2 is connected in device body 1 by tension spring 21, dial plate 3 is arranged in device body 1, the dial plate 3 is L shape, and dial plate 3 is supported on the branch plate 11 in device body 1, one end of dial plate 3 is docked on the limiting plate 12 of device body 1, the other end of dial plate 3 is docked on cable socket 2, after cable socket 2 is stretched out, the rotation of dial plate 3 is pressed, and limiting plate 12 and micro switch 32 are contacted synchronously.

[0017] As preferred embodiment, hanging spring pin 22 is provided at the connecting place of cable socket 2 and tension spring 21.

[0018] As preferred embodiment, micro switch 32 is arranged on circuit board 33.

[0019] The utility model discloses a kind of fork piece emergency stop pull mechanism suitable for mine telephone, dial plate, flat plate, branch plate are built into main frame by fork piece emergency stop pull structure using sheet metal structure design.The dial plate is combined together by passing through the branch plate with long hole, and the combination of dial plate and branch plate is connected as a whole by two sets of flat plate.The motion of dial plate rotating around branch plate is completed ingeniously by relying on the features design of the associated slot width, slot hole, plate width, notch, bending, concave and convex of dial plate, branch plate and flat plate, and the mutual conversion of horizontal displacement and vertical displacement is realized, which provides mechanism guarantee for emergency stop and pull linkage function.

[0020] Specifically, press down emergency stop button, and limit plate 12 is moved to trigger micro switch 32 and send emergency stop locking signal.Among them, button and limiting plate 12 are integrated, and micro switch 32 on flat plate circuit board 33 is triggered by pressing button limiting plate, and emergency stop locking signal is triggered.

[0021] The pulling member pulls out the cable socket 2, drives the rotating plate 3 to rotate around the supporting plate 11, and the rotating plate 3 forces the limiting plate 12 to move down to touch the micro switch 32 to send the emergency stop locking signal. Among them, the remote pulling of the cable line pulls out the cable socket 2, overcomes the pulling force of the tension spring 21, and then the protruding end of the tail of the cable socket 2 drives the vertical concave end of the rotating plate 3 to move outwards, forces the rotating plate 3 to rotate around the supporting plate 11, the horizontal end of the rotating plate 3 presses the vertical displacement of the limiting plate 12, the limiting plate 12 touches the micro switch 32 installed on the flat plate circuit board 33, and triggers the emergency stop locking signal.

[0022] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the concept and scope of the present application. Various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art without departing from the design concept of the present application shall fall within the protection scope of the present application, and the technical content claimed by the present application has been fully recorded in the claims.
